2.1 Marble floor

A, process flow

Try spelling number - grassroots repair - find the level, line - paving - inlaid copper - Sew - clean - maintenance.

B. Construction preparation

1), familiar with the design drawings, according to the drawings to understand the size of the various parts and practices, to clarify the relationship between the colors of the pattern.

2) According to the design drawings, to the site of the construction site to measure, and in combination with the actual situation, drawing blocks block diagram.

3), according to the horizontal baseline, pop up the ground elevation line, do a good job of ash cakes and ribs, the site of the drain should be made of radial ribs, gradient 0.5-1%, when the brick half brick appears, should be located in unobtrusive .

C, grassroots processing

The grassroots of the construction site shall be cleaned and rinsed, and the grassroots shall not shell, peel, sand, oil, etc. Grassroots treatment: Make the mortar, oil and garbage clean, rinse and dry, toilets and toilets to do waterproof treatment, such as 851 or two felt three oil, etc., the base layer may not shell, peeling, sand and other phenomena. Particular attention should be paid to corners, pipe files, etc., and we must splash water moist overnight. Toilets and toilets are self-sufficient at the bottom of the partition to make 150 high concrete walls waterproof.

D, material requirements

1) Block material acceptance, specification size should meet the requirements of the processing code list, require specifications Founder, smooth surface, can not have defects such as missing edges, falling angles, surface cracks and pollution discoloration.

2) The stacking and packaging of blocks and the light-colored stones are not bundled with straw ropes or straw curtains to prevent contamination. When stacked, store them according to specifications.

E, paving

1) Paving requirements: laying on concrete cushions and concrete floor slabs, construction should generally be carried out after plastering the walls of the ceiling. Shop the ground first, and then secure the skirting board.

2) Color numbering: Before the stone floor is laid, try to fight against the bulk material. Firstly, color, parquet, and number should be used to facilitate the registration.

3) Grassroots repair: check the leveling of the grassroots level. If the deviation is relatively large, it should be leveled and repaired beforehand, and the grassroots floor should be cleaned.

4) Find the level and the line: paste the horizontal ash cake on the plain concrete leveling layer and find the square in the line. One day before the construction, sprinkle the wetting base.

5), paving: Stone paving before the first water should be moist, dry after the reserve. First make a trial shop, in the leveling layer even brush a prime cement slurry, with the brush with the shop, with 20MM thick 1:3 dry cement mortar as a bonding layer. After the plate is installed, with rubber hammers and tapping, it is necessary to reach the laying height and to make the adhesive layer of the mortar even and dense.

6) Inlaid copper strips: After the stone veneers are laid and hardened, the garbage in the strips is cleaned, and the copper strips are fixed in the seams with epoxy resin. The upper strips of the copper strips are kept flat with the surface of the strips. Out of board.

7) Wipe the surface with a dry cloth to clean it.

8) After the construction is completed, do a good job of floor cleaning.

9) After installation, it is necessary to pay attention to product protection. After laying is completed, large-scale film covers shall be used, and cover plates shall be provided to prevent non-construction personnel from stepping on to prevent contamination and damage to the surface.

2.2 Floor tiles

A process flow

Grass-roots processing - ash cakes, marked bars - shop layer mortar (bottom layer) - brick laying line - pressing plate joints - caulking - curing.

B construction method

Shop-coating mortar (bottom layer): Brush the water evenly on the grass-roots level, and then use a broom to sweep it. A large area should be scanned to make a part of it, and the level, level, height, and level of Zi Cheng into a rough surface. Line: According to the test line or template, every three bricks, a control line, and pay attention to the road to be straight, uniform. Paving bricks: First, make the bricks soaked in water for 2 hours, remove them and wait for no water stains before paving. When paving from the outside to the inside, start from the doorway and spread evenly over the line of bullets. The board should not be too small to prevent sagging. Floor drain should be chiseled into corresponding shapes according to the shape of the floor drain, and the interface must be flush. Paving is flat and dense.

2.3 wooden floor

A process flow

The projectile horizontal line - the ball grid spacing line - adjust the joist to the horizontal level - lay the wool floor - lay the floor - sanding - paint.

B Construction preparation

The floor joists must be preserved before the pre-arrangement and the water content is up to standard.

C material requirements

Mouth plate: the board is not easy to decay, not easy to deform cracking, its width is not more than 120MM, the thickness should meet the design requirements.

D laying method

1) Construction of wood base layer

2) Wooden joists (keel)

The wooden joists are generally perpendicular to the ridge walls, and the distance between the joists is generally 300mm, and should be uniformly arranged according to the design requirements and the specific size of the room. There should be no less than 30mm gap between the wooden joists and the wall. The height of the wooden joists must be accurately measured using a spirit level meter, or they can be checked against the room's "50" standard line. Special attention should be paid to the relationship between the surface height of the wooden joist and the elevation of the lower edge of the door leaf and other ground. Check with a 2M ruler, and the gap between the ruler and the joist should not exceed 3 mm. If the surface is uneven, the backing plate can be flattened, flattened, or leveled at the bottom, but the cut depth should not exceed 10mm. The cut is treated with a preservative. When leveling with a backing plate, the backing plate is nailed with joists.

3) When the wood joists are leveled, nails shall be nailed with iron nails diagonally (450) on both sides of the joist and the joists shall be securely installed and kept straight. Wooden joists are treated with anti-corrosion treatment.

4) Surface coating construction

The surface layer construction mainly includes the firm and surface finishes of the surface slats. The fixing method is mainly based on nails. That is, the use of nails to fix the surface layer slats on the wool floor or the joists. The seams of the strip-shaped plates are generally formed in the flat mouth and in the form of a mouth.

5) The laying direction of the bar-shaped wooden floor should consider the convenience of nailing, firm fixing, and the use of aesthetic requirements. For walkways, aisles, etc., they should be laid in the direction of walking; while in the interior rooms, it is advised to ply along the river lines. For most of the rooms, follow the light, which is consistent with the direction of walking.

6) Starting from the side of the wall, the cores of the cored wood boards shall be arranged tightly in blocks, the gap shall not exceed 1 mm, the buckles of the boards shall be placed on the wooden joists, and the length of the nails shall be 2.0-2.5 of the thickness of the board. Times, hardwood boards should be drilled before nailing, the general aperture of 0.7-0.8 times.

6) Fix with nails. There are two kinds of nails: nails and dark nails. Clear nail method, the first to flatten the nail cap, the nail into the board, the same row of nail caps should be on the same line, and the nail cap must be punched into the board 3-5MM. The dark nail method first flattened the cap and pushed it diagonally from the concave corner of the plate. When nailing nails, the nails must have a certain angle with the surface, usually nailed 45 degrees or 60 degrees into the nail.

7) The wool floor under the double-layer wood surface layer can use blunt rib material whose width is more than 120mm. If nail planks or parquet are nailed on the floor, a layer of asphalt felt should be laid to prevent acoustic and moisture erosion during use.

8) After installation, it is necessary to pay attention to product protection. After laying is completed, large-scale film covers shall be used, and cover plates shall be provided to prevent non-construction personnel from stepping on and prevent damage to the surface.

9), wooden skirting construction

When nailing the skirting board, a long straight line should be played on the wall, and the surface of the skirting board should be planed, smooth, smooth, with tight seams, and the width of the gap between the floor surface and the floor should be no more than 1mm, and the flatness of the upper surface should not be greater than 3mm.

10) It is strictly forbidden to fix the wooden floor with steam gun nails, and the wooden floor fixing points are not allowed on the same straight line.
