4. WALL ENCLOSING STRUCTURES

4.1. In the practice of operating buildings and structures based on a metal frame, defects and damage to wall fencing are observed, which impair their performance and require their timely elimination in order to reduce in the future the more significant costs of work to strengthen and restore the load-bearing capacity and tightness of external walls.

Obvious and hidden defects in wall fencing, developing over time, can cause serious weakening of load-bearing structures and cause accidents in buildings and structures.

Timely strengthening and restoration of the load-bearing capacity and tightness of walls is an effective means of extending the period of normal operation and preventing accidents.

4.2. To correctly select and implement the most optimal option for strengthening or restoration, a qualified examination is necessary.

4.3. During operation and maintenance of wall enclosing structures, it is necessary to eliminate:

Deformations, damage and destruction caused by improper use of materials;

Deformations and damage to masonry and wall panel assemblies resulting from uneven settlement of foundations (cracks in masonry, destruction of seams in panels, displacement of support assemblies, etc.);

Deformations and damage resulting from the influence of thermal influences, especially in the walls of the main buildings of thermal power plants (cracks in the masonry along the axes of columns, spalling and destruction of vertical seams in panel joints, chipped bricks, spalling of mortar and other damage under the supports of beams, trusses, girders, jumpers, etc.);

Local destruction of masonry and wall panels in eaves and window sill areas, in places where drainage devices are installed;

Violations of the tightness of expansion joints;

Violations of connections between window and door frames and walls;

Displacements and distortions of wall panels in the plane and out of the plane of the walls;

Air permeability due to destruction of the sealing elements of the joints of wall panels (cement sealing, sealing gaskets, sealing mastics);

Detachment of protective layers in wall panels with exposure and corrosion of reinforcement;

Destruction and peeling of brick and mortar from the outside of brick walls;

Corrosion processes of embedded parts, support units and reinforcement of panels, as well as metal window frames, violation of anti-corrosion protection on these elements;

Destruction of the basement part of the walls due to soaking and defrosting, violation of the waterproofing in it.

4.4. If there are signs of unsatisfactory temperature and humidity conditions of enclosing structures (increased air humidity in the premises, local steam and destruction of walls from the outside in winter, massive swelling of the carpet on the roof, etc.), instrumental (including laboratory) checks of moisture accumulation in the building should be ordered. materials and environmental aggressiveness.

Sampling for analysis of the moisture content of materials should be carried out from areas with different temperature and humidity conditions of rooms and different fencing designs.

The simplest and most reliable way to determine humidity is the gravimetric method using the formula

Where W- material humidity, %;

R 1 - mass of raw material sample, g;

R 2 - mass of dried (to constant weight) sample at a temperature of 105 °C, g.

4.5. When monitoring the safety of wall enclosing structures, you must:

4.5.1. The facades of buildings should be periodically cleaned of dirt and dust, washed and painted (if there is a surface layer in the form of plaster) while simultaneously restoring the finishing layer, coatings of window sill drains, drainage devices, the outer sides of window sashes, and doors. Protruding parts of facades; Keep cornices, belts, plums, canopies in good condition.

4.5.2. The outer walls of buildings on the premises side should be periodically cleaned of dirt. For each individual room of a building or structure based on a metal frame, calendar periods for cleaning the walls must be established depending on the degree of contamination during the production process and the requirements for cleanliness of the room according to the conditions of the technological process and fire safety.

4.5.3. Periodically (once every five years) clean the temperature-sediment joints in the walls from clogging and restore all protective design coatings. Sealing joints with mortar or plastering is not permitted.

4.5.4. Do not allow the discharge of waste water and steam not provided for by the design through pipes passed through the external walls.

4.5.5. Do not allow snow to accumulate near the walls of buildings and structures in their basements, removing it at a distance of at least 2 m from the walls before the onset of a thaw.

4.6. The main operational quality of walls should be the constancy of their strength and heat-insulating properties. External wall enclosures must not accumulate moisture for one year. The humidity of building materials of external walls of buildings during operation should not exceed the permissible SNiP values.

Walls must meet the following requirements:

static- the walls must be sufficiently strong and stable when exposed to design forces and loads, and also meet fire resistance requirements;

thermotechnical- external walls must provide the temperature and humidity conditions required for sanitary conditions in the enclosed room.

4.7. External walls should be protected from moisture from condensation moisture, for which it is necessary:

4.7.1. Maintain the design heating and ventilation conditions in the premises. It is necessary to regularly ventilate the premises with outside air through window openings with control of the volume of air intake, its humidity and temperature in order to avoid violations of the design regime of the internal air environment. To automatically monitor environmental parameters (temperature, humidity), appropriate control systems are installed.

4.7.2. Avoid placing bulky equipment in the premises that impedes the free circulation of air near the walls, as well as storing industrial waste (slag, ash, shavings) and powdered chemical reagents (in the form of salt crystals, bulk, astringents) indoors or outside, directly against the outer walls. and etc.). All such waste must have special places for temporary storage (sites, containers, chests), and for chemical reagents - special cells or premises provided for by the project.

4.7.3. Periodically renew the vapor barrier layer on the surface of the walls as it wears out.

4.7.4. Additionally, insulate individual sections of walls moistened by condensation (in corners and at window sills) or install additional heating devices according to projects developed by the general designer or agreed with him.

4.7.5. Ensure constant removal of moisture accumulations in the interframe spaces of window openings.

In case of systematic accumulation of condensate, take measures to drain moisture into storm drains by installing appropriate drainage devices.

4.8. If wet areas or mold are found on the walls, the causes of their appearance should be identified, eliminated, and the specified areas of the walls should be dried.

The most common reasons for damp walls include:

Construction or condensation moisture;

Damage to technological, water supply or industrial and storm sewer underground, overhead or adjacent sections of networks and their devices;

Wetting associated with the operation of technological equipment.

4.9. To reduce the drying time of moistened walls, artificial drying of the walls should be used using additional heating or heating devices or devices. Drying the walls should be done based on the following conditions:

4.9.1. When using convective-type heating devices, the heated air near the surface to be dried should, as a rule, have a temperature no higher than 50-55°C.

4.9.2. When using radiation-type heating devices on heating surfaces, the temperature should be maintained at 65-70°C.

4.9.3. Heating and heating devices of the convective type should be used primarily for general drying of rooms, and of the radiation type - for drying individual sections of walls.

4.9.4. During the drying process, moisture must be removed from the premises using existing ventilation systems.

4.10. Increased wall moisture caused by surface or groundwater should be eliminated by:

Development and implementation of a special project to combat the wetting of walls by groundwater;

Streamlining the drainage of surface atmospheric water (repairing or widening the blind area, repairing gutters, etc.);

Replacement of failed waterproofing;

Additional waterproofing devices;

Laying new or additional drainage;

Drying walls using passive or active electroosmotic dehumidification;

4.11. It is necessary in all cases to eliminate increased moisture in walls caused by damage to technological equipment by:

Timely elimination of any sources of moisture;

Replacing wall material weakened by systematic waterlogging with a new one.

4.12. Do not allow, without agreement with the design organization or other specialized organization:

Changes in the thermal characteristics of walls moistened by condensate by installing external or internal plaster, increasing the insulation layer or other changes in the design of the walls adopted in the project; to correctly resolve such issues, calculations are required;

Punching holes in walls, creating additional openings for windows, doors and gates, adding walls, rearranging and dismantling walls and partitions without appropriate calculations and drawings, as well as punching continuous grooves or channels with a depth of more than 60 mm in stone walls with a thickness of less than 380 mm , with thicker walls, the depth of the channel should not exceed 1/3 of the wall thickness.

4.13. When maintaining walls made of large-sized panels, you must:

Ensure reliable fastening of the panels to the building frame and protection of embedded parts from corrosion by painting;

Ensure reliable sealing of panel joints.

4.154. The facade and internal surfaces of aluminum (metal) enclosing structures and window sashes that have a decorative or protective coating must meet the following requirements:

4.14.1. Enclosing structures should be systematically, at least once a year (in early spring), cleaned of dust and other contaminants.

4.14.2. When dry and wet cleaning of enclosing structures, it is not allowed to use chalk, sand, grated brick, soap containing free alkali, rough fabrics and other materials that can damage the surface of aluminum (metal) structures.

4.14.3. Enclosing structures should, as a rule, be wiped with soft cloths or sponges soaked in a solution of mild soap that does not contain free alkali, or in a solution of special detergents, and also wrung out.

4.14.4. Surfaces of structures covered with hard-to-remove dust or dirt should be cleaned with a neutral aqueous soap solution heated to a temperature of 50-60°C. After removing dirt, the entire surface should be wiped with a solution of mild soap or a solution of special detergents; internal surfaces - with soft cotton rags or a vacuum cleaner with hair brush attachments.

4.14.5. Cleaning and elimination of minor faults in enclosing structures, window frames and glazing should be carried out from cradles moving along the facade of the building along special guides using vehicles with retractable telescopic platforms or other similar devices with a folding cranked mast structure, and indoors - from stairs and service platforms.

4.15. Translucent enclosing structures and window openings made of glass block and glass profiles must:

4.15.1. Systematically (according to schedule) clean from dust and dirt with water and synthetic detergents.

The frequency of cleaning depends on the specific dust conditions of the environment, but should not be less than twice a year. For cleaning, brushes with soft synthetic fiber, rubber or foam sponges should be used.

Extension ladders used in this case, resting their upper ends on glass blocks or on glass profile elements, must have the ends wrapped in soft material (rubber, foam rubber, durable fabric with a cotton lining, etc.).

4.15.2. Temporary or permanent heating devices and other heat sources with temperatures above 70°C should be placed at a distance of at least 250 mm from the surface of glass block or profile glass fencing.

4.15.3. Elements of enclosing structures made of sheet or profile glass that have cracks, as well as broken glass blocks or glass blocks with significant cracks must be replaced. Glass blocks with small cracks may be left in the fence, but their condition must be monitored. Before carrying out repair work to replace damaged elements, it is necessary to fence off the dangerous area for safety reasons.

4.16. Plastered wooden surfaces of internal walls and partitions, painted with synthetic paints that are chemically resistant to alkalis, should be cleaned of contamination with warm soapy water, followed by rinsing with cold water. When washing, you can use a brush, brushes, sponges and rags.

Technical operation of public buildings and structures consists of a set of measures to ensure the functioning and trouble-free operation of all their elements and systems for at least the standard service life of the facility. Functioning is the direct use of a structure in accordance with its purpose. Let us consider further the basic requirements and rules technical operation of buildings and structures.

General information

The person supervising and caring for the object is appointed responsible for maintaining the document.

The technical journal is filled out in one copy for a separate large building/structure or a group of them.

Regulatory regulation

In the Russian Federation, the procedure for the technical operation of facilities is determined in federal laws and regulations adopted in accordance with them. For example, it is regulated by the Regulation POT R O-14000-004-98.

Some countries of the former USSR have similar regulations. Thus, the Technical Code of Standard Practice has been approved in the Republic of Belarus ( TKP) on the technical operation of buildings and structures.

Regulatory regulation of issues related to the use and operation of facilities is aimed at solving the following tasks:

• Ensuring the safety of the population, protecting the property of citizens and organizations, the state and municipalities.
• Preservation of the ecological situation at a level favorable for plants, animals and humans.
• Prevention of misleading owners about the safety of the physical parameters and properties of structures/buildings and premises in them.
• Ensuring the efficient functioning of facilities.

Repair

It can be current or planned. Ongoing work must be timely and systematic. They are aimed at restoring the surfaces of elements and structures and eliminating minor defects.

Scheduled repairs are carried out at least once every 3 years. If necessary, work can be carried out annually. The economic feasibility of frequent repairs is determined by engineers and financiers.

The need for unscheduled work is determined directly during the operation of the facility. It should be noted that delaying or delaying repairs may pose a threat to the health/life of workers (if the building is industrial) or residents (if the building is residential).

Overhaul

It can be of 2 types: selective and complex. In the latter case, all worn-out elements, equipment, and engineering structures are replaced.

During selective repairs, accordingly, work is carried out in relation to individual parts of the object. During this process, some structures may be strengthened.

Destructive factors

During the operation of the facility, it is necessary to take into account:

• External influence. Deformations and damage may be the result of man-made or natural disasters, or the influence of climatic conditions (constant wind, high humidity, low temperatures).
• Life cycle of an object. Each building has its own lifespan. It ends with the demolition of the facility.

The microclimate in the premises is of considerable importance for the efficient functioning of the building. A disorderly combination of temperature and humidity levels can lead to the destruction of materials and disruption of their adhesion to each other.

2.3.1.3. In order to protect the environment, it is necessary to ensure that landscaping is done on the territory of the power plant. In the absence of landscaping, organize its development and implementation. Monitor the condition of the landscaping.

2.3.1.4. Systematic monitoring should be organized, especially during rains and downpours, of the condition of culverts.

Places for passage of cables, pipes, ventilation ducts through the walls of buildings and structures in

within basements and plinths must be sealed with a waterproofing seal.

Malfunctions identified during the inspection must be eliminated by the production department of the enterprise that operates drainage networks and devices, or by specialized repair organizations involved.

2.3.1.5. The main tasks for organizing the operation of the territory of the energy enterprise directly near buildings, structures and in the adjacent territory are:

ensuring that the blind area is made without cracks or subsidence along the entire perimeter of the building or structure made of waterproof materials. If cracks appear at the junction of asphalt or concrete blind areas (sidewalks) to the walls, the cracks must be cleared and sealed with hot bitumen. If there is significant deformation of the blind area, it must be disassembled and rebuilt;

monitoring the serviceability of external water supply and heat supply networks, preventing their long-term operation with leaks in connections and through cracks in the walls of pipes, fittings and devices;

monitoring the serviceability of external networks of industrial stormwater and domestic sewerage, preventing their clogging, overflowing of control wells and spilling of sewage water throughout the territory.

2.3.2.9. If cracks are detected in stone, brick, concrete and reinforced concrete structures, observations of their development must be immediately organized using beacons. It is also necessary to conduct systematic observations of structures as a whole.

Diagrams of the location of cracks, dates of installation of beacons and the results of observations of cracks should be entered into the technical inspection logs of buildings and structures.

If cracks increase, take measures to temporarily reinforce structures.

2.3.2.10. A systematic check of the verticality of structures, building elements (walls, columns, overpass supports), chimneys and other building structures must be organized in a time frame coinciding with the measurement of foundation settlements. In case of increasing deviation from the vertical of individual structures or structures, or the appearance of a longitudinal deflection that threatens their stability, it is necessary to involve a specialized organization for examination.

2.3.2.11. Do not allow holes to be punched in supporting structures without written permission from the head of the enterprise.

3. INSPECTION OF THE TECHNICAL CONDITION OF BUILDING STRUCTURES OF INDUSTRIAL BUILDINGS AND STRUCTURES

3.1. Visual examination

3.1.1. The visual method of technical inspection of buildings and structures is the main method for performing technical inspections and identifying damage and defects in the building structures of buildings and structures of energy enterprises.

3.1.2. A visual inspection of a technical survey consists of inspecting structures or the object of inspection with an entry in the inspection log about noticed damages and defects, identifying the causes of their occurrence.

3.1.3. The results of visual inspections must be confirmed by measurements of all noticed damage and defects - deviations from the design, general and local deformations (deflections, shifts, curvatures, settlement, openings, length of cracks with probing of their depths, etc.).

3.1.4. In addition to a visual inspection of buildings and structures, the territory of the power plant with all its inherent structures and devices is also subject to a similar inspection.

3.2. Territory

3.2.1. When visually inspecting the territory of a power plant, it is necessary to identify the following violations of the rules of operation of buildings and structures, defects and damage;

storage of materials, reagents, garbage, scrap metal, equipment parts in bulk, release of waste water, steam, oils, fuel oil, spills of alkalis and acids directly at the walls of buildings and structures;

planting trees and shrubs in close proximity to buildings and structures (near walls);

the presence of flower beds, lawns, fountains in the area adjacent to buildings or structures;

all kinds of damage to road surfaces (potholes, subsidence, cracks, washouts, destruction or defects in the installation of curb stones, deformation of road surfaces from tracked vehicles, defects of builders, etc.);

damage to the subgrade of roads and driveways, roadsides, slopes (damage to the turf cover of slopes, landslides, gullies, subsidence, abysses, etc.);

malfunctions of external heating networks);

malfunctions of industrial storm sewerage within the territory of the energy enterprise (involve specialists from the heating supply area and underground communications to inspect);

destruction of structural elements of engineering road structures (overflow pipes, pressure walls, bridges, bridges, drainage ditches, ditches, etc.) within the territory of the power plant, blockages of ditches, ditches, overflow pipes, etc.;

malfunctions of drainage systems of embankments and excavations;

defects and damage to blind areas of buildings, structures and detached supports of structures; cracks, subsidence, reverse slopes, destroyed areas, cracks at junctions.

3.3. Buildings and constructions

In industrial buildings and structures, visual inspections must be carried out primarily on the most vulnerable places, which must be identified for each building and structure. The most vulnerable areas of buildings and structures include:

places where structures meet: joints of panels, walls, coverings, floors, interfaces between walls of buildings of different heights;

coupling of the roof with pipes crossing it, parapet walls, walls of adjacent high-rise rooms, protruding above the roof;

places where communications pass through walls: vapor pipes, exhaust pipes of safety valves;

3.4. Load-bearing reinforced concrete structures

3.4.1. The main task of a full-scale inspection of load-bearing reinforced concrete structures is to determine their technical condition by identifying damage, defects, deformations and the causes of their occurrence. Surveys of this type should include:

determination of defects and deformations, as well as actual physical and mechanical characteristics of materials and structures (concrete, reinforcement, rolled steel, etc.);

determination of the general spatial position, type of structure and compliance with its design;

checking the compliance of actual loads with design ones (their magnitudes and directions);

making engineering decisions on the maximum possible partial restoration of the load-bearing capacity of structures or their replacement.

3.4.2. A visual inspection should identify structures or areas thereof with visible defects, as well as the most vulnerable structures (those in the most unfavorable operating conditions). The results of visual examinations should reveal whether additional instrumental studies are required and, if necessary, determine their program.

3.4.3. Visual inspection and determination of the technical condition of reinforced concrete structures of buildings and structures should include identification of:

condition of protective coatings (paint and varnish, plaster, thermal insulation, protective screens, etc.);

presence of wet areas and surface efflorescence;

state of strength characteristics of the protective layer;

the presence of cracks and spalls of the protective layer;

violation of the adhesion of reinforcement to concrete;

the presence of corrosion of reinforcement (by control punctures of the protective layer);

the presence of visible defects in concreting structures remaining from the construction period.

3.4.4. If there are wet areas and surface gouges in the concrete, it is necessary to determine the size of these areas and the reason for their appearance.

3.4.5. During inspections, it should be taken into account that the following types of cracks are most often found in reinforced concrete structures:

in columns - vertical on the edges of the columns, horizontal;

in beams and purlins - inclined at the supporting ends, vertical and inclined in the span sections;

in slabs - in the middle part of the slab, directed across the working span with maximum opening on the lower surface of the slab; radial and annular in the middle with possible separation of the protective layer and destruction of the concrete slab; on supporting areas, directed across the working span with maximum opening on the upper surface of the slab.

3.4.6. Detection of cracks and destruction of concrete of load-bearing structures should be done by examining their open surfaces, as well as by selectively removing protective coatings from structures. In this case, it is necessary to determine the position of the cracks, their direction and the amount of opening, which is measured using a magnifying glass. The depth of cracks is determined using special probes.

To determine the degree of stabilization of cracks that do not pose a danger at the time of inspection, observations of them should be organized, for this it is necessary:

install gypsum or cement beacons on all the most characteristic cracks and organize monitoring of their condition;

Mark the boundaries of the observed cracks (beginning and end) with paint and clear, clear lines, and mark the date of observation along these lines;

Observe cracks for 20-30 days. If during this time the beacons turn out to be intact, and the length of the cracks does not increase, then their development should be considered complete;

A sketch of the cracks, their development and the installation of beacons should be included in the technical log for the inspection of building structures.

Vertical cracks on the faces of columns experiencing static loads may appear as a result of excessive bending of the working reinforcement bars. This phenomenon can occur in those columns and their areas where clamps are rarely installed.

The presence of such a reason should be verified by selective openings of the protective layer.

3.4.7. It should be borne in mind that horizontal cracks in reinforced concrete columns do not pose an immediate danger if their width and depth are small, but through such cracks air and moisture can enter the reinforcement and cause corrosion of the metal.

3.4.8. If inclined cracks are detected at the supporting ends of beams and girders, the latter must be classified as structures with insufficient load-bearing capacity along inclined sections, where shear stresses act. Vertical and inclined cracks in the spans of beams and girders also indicate their insufficient load-bearing capacity to absorb a bending moment. To confirm these signs, verification calculations should be performed.

3.4.9. Monolithic slabs with cracks in the supporting sections directed across the working span should be classified as structures with insufficient bearing capacity for bending support moment.

3.4.10. Cracks are often observed in reinforced concrete elements of buildings, the cause of which is corrosion of the reinforcement from the effects of penetrating moisture from the environment through pores and defects in the protective layer. When corroded, reinforcement bars increase in volume due to the formation of metal oxide crystals on their surface, and this causes cracks to appear in the protective layer of concrete, usually located along the bars. To identify this feature, selective opening of the protective layer is necessary.

3.4.11. It should be borne in mind that during operation, cracks appear at joints and on embedded connections due to shrinkage phenomena in the embedded concrete. The presence of such cracks indicates that the tightness of the solution to the metal is broken, which facilitates access to moisture and air and creates conditions for the process of corrosion of the reinforcement. Such areas of grouted joints should be classified as structures with insufficient concrete density and moisture-permeable structures that require corrosion protection.

3.5. Load-bearing metal structures

3.5.1 The main objectives of the inspection of metal structures should be: identification of their general technical condition, the possibility of their further operation, wear patterns in order to be able to develop optimal measures to reduce wear and determine the service life of structures.

3.5.3. The main defects and damage to metal structures, which should be identified primarily during field inspections, are:

in welds: defects in the shape of the weld - incompleteness, sharp transitions from the base metal to the deposited metal, sagging, uneven weld width, craters, breaks;

defects in the weld structure - cracks in the seams or near the seam zone, undercuts of the base metal, lack of penetration along the edges and along the cross-section of the seam, slag or gas inclusions or pores;

in rivet joints - notches, displacement from the axis of the rods and small dimensions of the heads, excess or lack of height of countersunk rivets, oblique rivets, cracking or rowan rivets, cutting of metal by crimping, loose filling of holes with the body of the rivet, ovality of holes, displacement of the axes of the rivets from the design position ; mobility of rivets, separation of heads, absence of rivets, loose connection of packages;

in structural elements - deflections of individual elements and the entire structure, helicality of elements, bulging, local deflections, bending of nodal gussets, corrosion of the base metal and metal of the joints, deviations from the vertical, cracks.

3.5.4. Deflections, bends, bulging and similar defects and damage to structural elements and structures in general must be detected visually. Their dimensions are determined using thin wire and a steel ruler. Deviations of structures from the vertical are determined using a theodolite or a plumb line and a steel ruler, and height displacement is determined using a level and a regular rod and steel tape measure.

insufficient sealing of production equipment, leading to excessive release of steam and moisture;

malfunctions of local and general ventilation devices;

absence or violation of hydro- and vapor barrier of walls in industrial and domestic premises with humid and wet operating conditions.

3.6.6. If there is delamination of the masonry, it is necessary to open the exfoliated layer and measure the depth and area of ​​the delamination. It is necessary to simultaneously identify the main causes of delamination (thermal effects, systematic wetting with liquids - atmospheric, mechanical, etc.).

3.6.7. When cracks are detected in wall structures, it is necessary to determine the nature and type of cracks, the reasons for their appearance, their number, opening width, length and depth.

3.6.8. All wall defects discovered during the inspection (delaminations, masonry, cracks, weathered areas, areas with corrosion of the textured reinforcement layer, panel fastening points significantly affected by corrosion, etc.) are plotted on drawings, which provide textual explanations containing information about identified defects.

3.10.1. Field examinations of foundations and foundations in visible areas of the latter (in basements) are periodically necessary as a preventive measure that facilitates timely detection of the initial processes of deformation of foundations and foundations due to uneven settlement or heaving of foundations. These deformations of bases and foundations affect the condition of all other structures of buildings and structures, and therefore protecting them from destruction and timely restoration is one of the main tasks of operation.
