wall construction technology

1. Check whether the concealed works within the scope of work meet the design requirements, whether the embedded pipes are qualified, and whether the position and quantity of ground outlets are in line with the drawings of various types of work.

2. Some wall bodies are constructed by dry hanging stone. The thickness of stone is standard 25; The thickness of dry paste is 21.

3. Adopt high-quality galvanized angle steel with corresponding bearing coefficient as the skeleton.

4. For the expansion screw holes installed in the skeleton, attention must be paid to avoid all kinds of pipelines embedded in concealed works.

5. Check the quality of the stone, with square specifications and smooth surface.

6. Trial paving, pre-arrangement, numbering and classification of stone with large area, many lines and great natural color changes will make the patterns, colors and textures even and smooth.

7. Before installation, look for horizontal lines, vertical lines and frame lines.

technical requirements for ground paving

1. Check whether the concealed works within the scope of work meet the design requirements, whether the embedded pipes are qualified, and whether the position and quantity of ground outlets are in line with the drawings of this type of work.

2. check whether the flatness, verticality and strength of the operation surface meet the design requirements, and whether it is necessary to make a second leveling.

3. Check the quality of the stone, with square specifications and smooth surface.

4. Trial paving, pre-arrangement, numbering and classification of stones with large area, many lines and great natural color changes make the patterns, colors and textures even and smooth.

5. Before paving, look for horizontal lines, vertical lines and frame lines.

6. 24 hours after paving, it is forbidden to trample or collide with the stone, so as not to cause damage and looseness.

7. The paving of granite ground should be carried out in two processes. First, C21 fine stone concrete leveling layer with a thickness of 41 (see the construction drawing for details when the building layer thickness is 51 or 71) should be adopted, and pipelines should be laid. After the leveling layer dries and shrinks stably, the granite should be paved with dry cement sand of 1: 2.5, and the paving can not be completed in one process.

8. Before paving, brush the cement slurry with water cement ratio of 1.4-1.5 on the base (or leveling layer) first, and spread the cement mortar layer with the brush;

9. Pave the hardened cement mortar binding layer (leveling layer). The length of the paving mortar should be more than 1 m, and its width should be 21- 31mm wider than that of the flat plate. The thickness of the paving mortar is 11-15mm, and the virtual paving mortar on the floor is 3-5mm higher than the elevation line.

(2). Wood veneer

Material and process requirements:

1. The main materials are rosewood, mahogany, etc. It is suggested that all wood veneers should be entrusted to professional manufacturers for construction. Surface decorative wood belongs to AA-class products that meet international standards.

2. The wood square, whether made in China or imported, should be grade A products with the same texture and color as the surface decorative board, and the moisture content should be controlled within 1.2%.

3. All base wood used for decoration shall be treated with fire prevention and moisture prevention.

4. The color of wood veneer shall be determined by both Party A and the designer.

(3). product requirements of porcelain vitrified brick

products must meet the requirements of national standard BG/T4111.1-1999, and the following indicators should be met:

water absorption: 1.18%

fracture modulus: 39Mpa

length and width:+1.8 mm < Vertical angle:+1.15%

Glossy: 65

Mohs hardness: 6

Radioactivity: A

Pollution resistance: 3

45-degree cutting according to design requirements

Tile construction technology:

1. The base to be tiled should be straight, and the surface is not harmful to decorative tiles.

2. Before tiling, you should choose tiles with uniform color and uniform size, so as to achieve uniform joints, pre-arrange bricks, and play the dividing line of color variation and vertical and horizontal control lines.

3. The tiling should start from the lowest layer, and hang the thread according to the benchmark, and spread it from bottom to top row by row. The back of the brick should be coated with cement paste, and the thickness should be generally controlled within 2-3 mm. After pasting the wall, use a rubber hammer to strike hard to make the brick stick firmly. At the same time, use a pressure ruler to level the brick and epithelium. After paving a row, you should re-check each brick. If you find an empty drum, you should lift it in time and paste it again.

4. After setting, after the initial setting of cement paste, clean the brick surface with clear water, fill in the joints with white cement slurry (colored bricks should be adjusted with mineral pigments according to design requirements), and wipe the surface with cotton yarn and cloth after completion until there is no residual ash trace.

5. Quality requirements: the varieties, specifications, colors and patterns of ceramic tiles must meet the design requirements, and the quality must meet the current standards; Tile inlay must be firm, without hollowing, skew, lack of stare blankly, corner drop and cracks; Surface tiles should be smooth, clean, uniform in color, free from alkali stains and obvious gloss damage, with dense joints, straightness, uniform in width and color, plates with yin and yang angles pressed to the right parts where the whole brick is used, cut and matched with the whole brick sleeve, with neat edges, smooth skirting, face sticking and other wounds, consistent in thickness of protruding walls, correct in slope direction of flowing water, and straight in drip line.

6. Allowable deviation: the verticality of the facade shall not exceed 2mm within 2111mm, the surface flatness shall not exceed 3mm within 2111mm, the square angle of yin and yang shall not exceed 3mm, and the joint height difference shall not be less than 1.5mm.

7. Finished product protection: the slurry and condensate shall be removed from the brick surface immediately after the construction, so as to make the brick surface clean and free of sundries; Make the finished surface clean, seamless, chip-free, undamaged, firmly bonded, or free from other defects; When the construction operation may damage the tiled wall, protect the tile wall with protective cardboard or other protective covering.

(4). Latex paint facing

Material performance requirements

1. Cooked rubber powder, using high-quality imported brands recognized by the owner and design institute.

2. Lide powder, which is smooth, white and free of impurities.

3. Gypsum powder, with natural gypsum as the main material.

4. latex paint must meet the design requirements, and imported or joint venture brands with fine texture and stable performance are preferred. Try to use the original color series latex paint (Dulux is recommended).

5. It is recommended to use matching putty and matching primer for latex paint.

Construction technology requirements

1. Repair the missing edges and corners of the base with 1: 2.5-1: 2 cement mortar, fill the surface pits and gaps with putty, and the base surface should be clean;

2. Scrape the putty at the grass-roots level with a scraper. It is required to scrape it thin, collect it cleanly, and be even and smooth without flying thorns. After the putty is dry, use No.1 sandpaper to polish it, pay attention to protecting the edges and corners, and ensure that the surface is smooth, the line angle is straight and uniform.

3. repeat step 2, which must be repeated twice, depending on the smoothness of the base;

4. Apply the primer, and brush it up and down, and the last row of brush strokes is immediately followed by the previous row of brush strokes, which are connected with each other. Pay attention to it.
