PLASTERING AND PAINTING WORKS IN LARGE PANEL HOUSES

I... APPLICATION AREA

The technological map is developed on the basis of the application of methods of scientific organization of labor and is intended for use in the development of a project for the production of work and the organization of work and labor at the facility.

The map is compiled for plastering and painting works on a 60-apartment building series 1-467 A-2 and can be used when performing plastering and painting works in large-panel buildings of other types.

II... INSTRUCTIONS FOR WORK PRODUCTION TECHNOLOGY

a) Plastering work

1. Plastering works are performed at the beginning on the 1st floor, then on the 2nd, 3rd and subsequent floors with transitions within the floor from one plot to another. Plastering works are carried out in those sections where structures are not being installed.

Before plastering, brick and concrete surfaces are thoroughly cleaned of dust.

2. Support tables for the canopies of the entrances and niches above the canopies are plastered on a metal mesh with a mesh size of 10 × 10 mm or along weaving made of wire with cells not larger than 40 × 40 mm . Plinths, platbands and door frames are coated with a solution to smooth the surface.

3. When facing walls and ceilings in the vestibule with sheets of dry plaster on the insulation, the sheets are attached to wooden blocks with thin nails (roofing) with wide caps. Heads of nails are sunk into sheets and putty.

4. When cutting with a template of rustication on the ceilings, the grooves in the joint of the slabs are thoroughly cleaned of dust and abundantly moistened with water, and then filled with cement mortar to the full depth and smoothed out.

To accelerate the setting of the cement mortar, about 1-2% gypsum is added to it with thorough mixing of the mixture.

5. Due to the small volume, plastering works are intended to be carried out manually.

6. In winter, plastering work begins after the completion of installation, roofing and glass work. The air temperature inside the building must not be lower than +8 ° С (when measured at a height of 0.5 m from the floor).

7. Window sills should be plastered before the onset of cold weather. When plastering them in winter, it is necessary to protect the plasterboard from premature freezing by electric heating, insulation with felt, etc.

8. Plastering is carried out from a solid, stable platform or table. Moreover, you can work at the same time only in one tier in height.

9. Workers performing work must comply with the requirements of SNiP III - B .13-62 "Finishing coatings of building structures. Rules for the production and acceptance of work "and safety rules in accordance with SNiP III - A

b) Painting work

1. Prior to the commencement of painting work in the finished premises, all general construction, electrical and plumbing works must be completed, as well as glazed window sashes and balcony doors.

The quality of the assembled products must be such that their surface does not require additional finishing work, except for sealing joints, putty and painting.

On the surface of the products there should be no cracks, chips, grease and rust stains, mortar overflows, and exposed reinforcement.

2. The painting work should be started after the completion of the building installation, starting from the top floor.

3. The surfaces to be painted are pre-cleaned from dust. The moisture content of the plaster before painting should not exceed 8%, and for wooden surfaces - 12%.

4. Before painting, rough surfaces are putty and smoothed, and small cracks are embroidered and sealed with mortar to a depth of 2-3 mm. . Grinding of the putty and greased places and smoothing of the surfaces are performed using a pneumatic trowel.

5. Paints, pastes and putties are prepared in a color workshop and delivered to the construction site in finished form.

To supply compressed air to the power tool, pneumatic stands from solid-drawn gas pipes with air intake valves on each floor are installed in the stairwells. The pneumatic stands are connected to a compressor installed on the first floor of the staircase.

In turn, paint-injection tanks are connected to the pneumatic stand with rubber hoses, which supply painting compounds to spray guns, pneumatic rollers and fishing rods.

6. Priming and painting of ceilings is carried out using an electrospray gun with a universal fishing rod, and oil painting of walls and floors is performed using rollers with pneumatic supply of painting compositions.

Smooth foam rollers are used to paint doors, and profiled foam rollers are used for window sashes.

Pipes are painted with special brushes, and metal railings of staircases and balconies - with paired foam rollers.

The second time, the floors are painted with oil paint, heated to a temperature of 25-30 ° C.

7. In winter, the air temperature inside the building should not be lower than +8 ° С (when measured at a height of 0.5 m from the floor).

8. Workers performing painting work must comply with the requirements of SNiP III - B .13-62 "Finishing coatings of building structures. Rules for the production and acceptance of work "and safety rules SNiP III - A .11-62 "Safety in construction".

III. WORK PRODUCTION TECHNOLOGY

1. The technology for the production of works on painting metal structures with the help of an electro-paint manual installation UREG-1 consists in performing organizational and preparatory operations, as well as operations for applying a paint and varnish coating.

2. Organizational operations are performed prior to the start of painting. This requires:

• instruct workers on the rules for the production of work;
• check the presence of solvents and paints and varnishes for the entire scope of work. All materials must be of the same batch;
• arrange all the tools and devices necessary for work and elimination of possible malfunctions within the working radius of the workers;
• ensure delivery of materials To workplaces using hand carts.

3. It is forbidden to allow persons who have not undergone appropriate training and instruction to work on the UREG-1 installation.

4. Before starting work, it is also necessary to prepare the surfaces of metal products in the UREG-1 electric paint installation, prepare primer and paint compositions.

5. Surface preparation of the metal structure consists in removing rust and corrosion foci of the day to ensure proper adhesion of the paint layer to the base.

6. Work on preparing the surface of metal products for painting is performed in the following technological order:

• cleaning the surface from dust and dirt;
• cleaning the surface from rust;
• degreasing surfaces;
• grounding of products.

7. Before painting, the surfaces of metal structures must be cleaned of dust, dirt, splashes of solution and other contaminants using scrapers and rags.

8. Surfaces of metal structures 3-4 hours before painting should be cleaned from rust using steel brushes or by chemical means and degreased.

9. Cleaning from rust by chemical means and simultaneous degreasing are performed with washing composition N 1120, which includes (in %): phosphoric acid - 30-35; hydroquinone - 1; butyl alcohol - 5; ethyl (denatured) alcohol. twenty; water - 39-44.

10. Work on the chemical cleaning of metal surfaces with a washing compound consists in applying it with a rag, brush or roller to the surface to be treated, and after 30 minutes of holding - cleaning the surface with metal brushes and rinsing with N 107.

11. If there are cavities and solid rust on the surface of metal structures, it is chemically cleaned using a composition of three parts of hydrochloric acid and one part of sulfuric acid, followed by neutralization of the surface with an alkali solution (NaOH) and rinsing with water.

Degreasing of the surface in these cases is carried out according to the technology adopted at the enterprises of the Production Association Mospromelektrokonstruktsiya.

12. Metal products to be electrocoated must be grounded with a device with a resistance of at least 100 ohms.

13. It is forbidden to apply paints and varnishes on the surfaces of uncleaned and ungrounded metal products and structures.

14. Preparation of paints and varnishes for use in electro-painting consists in bringing priming and painting compositions to the required viscosity, checking their electrostatic properties (specific volume resistance, dielectric constant, etc.).

15. When preparing paints and varnishes, as well as controlling the painted surface, you should use:

• compressor СО-7А;
• kilovoltmeter type S-100;

32. In the process of work, having installed UREG-1, the paint or primer composition from the paint-injection tank under the action of compressed air enters the spray gun, where the compressed air for spraying is supplied. When you press the trigger of the spray gun with your finger, the channels open along which the movement of the paint composition x air begins.

Under the action of the dynamic air pressure, a high voltage circuit (10-14 kV) is closed using a pneumatic relay, in which the corona electrodes are located. The sprayed and electrically charged paint composition increases this charge in the flow of ionized air and settles on the grounded product to be painted.

33. The color of the painted metal structures must correspond to the project.

34. Painted surfaces should have a uniform texture. Translucence of underlying paint layers, as well as stains, splashes, bubbles, blockages, wrinkles, smudges, omissions, etc. not allowed.

35. After finishing the painting work, the spray tank, spray gun and the entire paint supply system must be rinsed out. Flushing of the spray system is carried out after the end of each work shift.

36. It is forbidden to leave the UTEG-1 unit in a non-washed state and with a paint-heating tank filled with paint.

IV. METHODS AND METHODS OF LABOR

1. Work on the preparation and painting of metal structures with a manual electric paint installation UREG-1 is carried out by a team of two people

• painter (operator) 3 digits (М1) 1
• painter (operator) 4 digits (М2) 1

Means of mechanization are serviced by an electrician of the 4th category, working in the shop.

2. Organization of the workplace when painting metal structures depends on the painting conditions.

3. The scheme of the organization of the workplace in the shops of centralized painting at a stationary post is shown in Fig. one.

4. The layout of the workplace when painting metal structures on the production line of centralized workshops is given in Fig. 2.

5. The layout of the workplace when painting metal structures in open areas is given in Fig. 3.

6. The performance of work on the organization of the workplace with this card and costing is not provided for, but is decided additionally in each specific case.

7. The technological process of staining with the help of a manual installation UREG-1 provides for a complex of technological operations that do not depend on organizational factors.

This complex includes operations for the preparation of metal structures, painting materials, installation and painting itself.

8. The calculation of labor costs and the schedule of the labor process are drawn up for painting 100 square meters of metal structures of medium complexity and are given in tables 5 and 6.

9. Time norms for individual technological operations are adopted according to ENiR, Sat. 8 with the introduction of coefficients reflecting additional costs, as well as based on the productivity of the UREG-1 unit.

10. Complex of operations: preparation of metal structures for painting, consisting in cleaning structures from dust, rust, scale, spray of solution, etc., are performed by painters M1 and M2. Clean surfaces from dust and dirt with a rag; from rust - with a metal brush or chemical agents, applying them to the surface with a rag, brush or roller, followed by removal. After removing the rust, finally wipe the surface with a rag.

11. The preparation of working paint compositions is carried out by painters M1 and M2 in an amount that does not exceed the replacement requirement. At the same time, the primer and paint compositions are diluted to the desired viscosity, which is controlled with a VZ-4 viscometer, then the volume resistivity is determined with the PUS-1 device and the dielectric constant - with an E-4-4 quality meter, if necessary, they are corrected by introducing the required amount into the composition emulsifier OP-7. The finished composition is filtered into an injection tank through a semi-compact mesh 05.

12. The preparation of the UREG-1 electric paint unit is performed by painters M1 and M2. At the same time, by external examination, they are convinced that there is no damage to the installation elements; all handles on the panel are set to the "Off" position, if necessary, remove the preservative grease from the surfaces of the installation with a cloth soaked in solvent. Remove the plugs from the fittings intended for connecting the spray gun, connect the spray gun hoses to the fittings according to the inscriptions, and the cable to the excitation unit, connect the unit to the compressed air network and the power supply network, ground the unit and products.

13. Check the operation of the agitator by turning the knob on the top cover of the agitator pneumatic motor by two turns, and then put the tap with the inscription "Agitator" in the "Open" position.

The frequency of switching on, the duration and intensity of the stirrer are set depending on the type of paint and varnish material.

If the air pressure in the network is 0.45-0.5 MPa, then for normal operation of the sprayer it is recommended to turn on the agitator during breaks in the operation of the sprayer.

14. Set the torch width required depending on the coloring of the products, for which the nozzle is removed from the sprayer and the diaphragm is placed in one of the positions marked with numbers on it.

15. Open the tap with the inscription "Air pressure", set the required spray pressure in the range of 0.45 - 0.6 MPa. Set the movable nut on the spray head in the position when the mark at its front end coincides with the mark on the union nut, on the first revolution from the last, the marks on the movable nut correspond to the optimal sprayer operation: at the front end - at an air pressure in the network of 0.45 MPa, at the rear - at 0.6 MPa.

16. Set the "Generator Power" switch to the "Mains" position - the green light comes on, turn on the sprayer. In this case, the red light should light up, then, by rotating the "High voltage" knob on the control panel, set the current 75 + 100 μA by the microammeter.

17. Set the required paint pressure, but not more than 0.4 MPa, using a valve with the inscription "Paint pressure" and a regulator.

18. Confirm the presence of the affect of coverage by testing a grounded metal cylinder with a diameter of up to 100 mm without turning it. The best coverage effect is achieved by turning the movable nut on the spray head in the forefathers of the marked area.

19. When drawing up a work schedule and calculating labor costs, it was taken into account the execution of an operation for the preparation of electro-paint equipment twice per shift (at the beginning of the shift and after a lunch break).

With a one-time preparation of the equipment, it is necessary to make adjustments to the table. 5 and 6.

20. Technological operations for applying primer and paint layers on the surface of metal structures using the UREG-1 unit are performed by painter M2; first, he checks the position of the "Paint supply" and "Paint pressure" valves on the installation (they must be open), then takes the spray gun in his right hand, holding it with his left, and by pressing the trigger creates a torch of paint, directing it to the product to be painted.

21. When applying the primer and paint layers, the spray gun must be kept from the surface to be painted at a distance of 250-350 mm, since with an increase in this distance, the loss of paint and varnish material increases.

22. At the end of each shift or at the end of painting work, the painter M2 pours paint from the spray tank and pours 3/4 l of solvent into it, connects the sleeves and closes the tank with a lid. Sets the "Paint supply" and "Paint pressure" taps to the "Open" position, opens the spray gun and, pouring the solvent into an arbitrary container, flushes the paint supply system until the traces of paint disappear. Then he wipes the surface of the sprayer with a cloth soaked in solvent.

23. When painting metal structures located higher than 3.5 m from the floor or ceiling mark, work must be performed from a mobile platform.

24. When calculating the time norm for painting metal surfaces, the work of the installation from the ground was taken into account, when working from the scaffold, the time norms and prices for priming and painting in table. 5 and 6 must be multiplied by a factor of 1.25 in accordance with ENiR, sb. 8, section III.

a) when painting with glue and oil compositions, the moisture content of the plaster or concrete before painting should not exceed 8%, and the moisture content of the wood of the painted parts should not exceed 12%;

b) surfaces painted with glue paints should not stain and change color tone; surfaces should have the same tone and careful shading; stains, streaks, drips, splashes, brush hairs, shallowing are not allowed;

c) surfaces painted with oil, enamel and varnish should have a uniform texture; not allowed: transillumination of the underlying paint layers, stains, wrinkles, drips, gaps, film pieces, putty irregularities and brush marks; local curvatures of lines and shading with improved quality of work should not exceed 2 mm,

9. When performing interior painting work, the following safety rules must be observed:

a) when removing old oil paint on the surfaces of walls and streams with devices with an open flame (blowtorches, etc.), continuous ventilation of the premises must be ensured.

Internal painting work with the use of compounds that emit volatile vapors harmful to human health should be performed with open windows or mechanical ventilation, which ensures at least two air changes per hour. It is not allowed for people to stay in rooms freshly painted with oil or nitro compounds for more than 4 hours.

Painting work in rooms with the use of nitro paints and nitro putties should be carried out with a fourfold air exchange per hour;

b) when performing painting works using pneumatic devices, as well as quick-drying paints and varnishes containing volatile solvents, workers are supplied with respirators and goggles;

c) in rooms where painting with water compositions is carried out, the electrical wiring must be de-energized during the painting work;

d) it is prohibited to use lead white separately and as an integral part of paints, as well as benzene and leaded gasoline as solvents;

e) when cooking or heating drying oil and its substitutes, as well as rosin, it is prohibited to fill the container by more than? its volume and add volatile solvents to the container without removing it from the heat;

Instructional technological map

Lesson topic: Painting the surfaces of walls and ceilings with lime compounds, brushes and rollers.

The task: To paint the surfaces of walls and ceilings with lime compounds.

Target: To develop skills and abilities for painting the surfaces of walls and ceilings with lime compositions.

Tool

Instructions on how to get the job done

Preparation of lime paint composition

Capacity, construction mixer

Lime dough is diluted in 6 liters of water, table salt dissolved in 0.5 liters of water is added, and everything is mixed. Then add water to 10 l and get a white color. If a color tint is needed, then a pigment soaked in water is added to the white composition and mixed thoroughly. For staining, various coloring compositions or colors are prepared.

Surface priming

Brush

The surfaces are cleaned, moistened with water and primed. When preparing a lime primer with table salt, the lime dough is diluted in 5 liters of water and table salt dissolved in boiling water is added to this solution. With constant stirring, pour in water up to 10 liters. Lime dough consumption - 2.5 kg, salt - 0.1 kg.

Surface painting

Brush

Lime paint is used both outside and inside buildings for covering porous surfaces and plastered with lime mortars, brick walls, as well as for painting damp and cold rooms. Apply the composition with a brush. When painting with a brush, put two or three thin layers on the still wet previous layer.

It must be remembered that lime paint is usually applied with horizontal movements, and shading is done vertically.

Safety precautions.

Before starting work, it is necessary to undergo a safety briefing, put on overalls, inspect the workplace, check the correct placement of materials and the serviceability of tools, inventory, devices. The tool must be used as intended. When painting surfaces with lime compounds, the painter must use personal protective equipment - goggles, cotton or rubber gloves, and a respirator. All operations of the technological process must be carried out in compliance with the rules of technical safety. When working, it is very important to choose the correct working position. This not only reduces fatigue, but also largely protects against injury of all kinds. After finishing work, clean the tool, clean the workplace, carry out personal hygiene.
