process flow

Basic treatment → keel and floor construction → overall positioning and unreeling → lining and precast mosaic construction → surface construction → trimming and finishing → other finishing is completed.

Construction method

1, grass-roots treatment:

(1) On the wall surface requiring soft package, elastic lines shall be drawn according to the vertical and horizontal keel spacing required by the design. When there is no requirement in the design, the spacing should generally be controlled between 400-600mm ... Then punch holes with electric hammer according to the played lines, the hole spacing is less than 200mm, the aperture is greater than φ 12mm, and the depth is not less than 70mm, and then the wooden wedge after anti-corrosion treatment is driven into the hole.

(2) When the wall surface is plastered at the grass-roots level or the adjacent room is wet, the wall surface must be moistureproof after the wooden brick is finished, and then the next working procedure is carried out.

(3) The base surface of the soft package door leaf shall be painted with bottom oil at least twice, and then the handle and door lock shall be installed.

2, keel, floor construction:

(1) Install wooden keel with wooden screw on the embedded wooden brick, with the length of wooden screw >; Keel height +40mm. The wooden keel must be treated with anti-corrosion first, and then the surface must be treated with fire prevention. When installing the keel, it must be leveled with a guiding rule of not less than 2m. The gap between the keel and the wall should be filled with a wooden wedge that has been treated with anti-corrosion. The wedge spacing should not be greater than 200mm, and the surface roughness of the installed keel should be less than 2mm within 2m.

(2) Nail the bottom plate on the wooden keel. When there is no requirement in the design, the bottom plate should adopt environmental protection joinery board or environmental protection jiuli board, and the length of nails should be ≥ +20mm thick. When the wall is light steel keel gypsum board or light steel keel magnesium board, the wooden keel can not be installed, and the bottom plate can be directly glued to the wall, and the nails can be paved with self-tapping nails. Thickness of gypsum board or magnesium board after self-tapping nail length ≥ bottom plate+10mm, and self-tapping nail must be fixed on light steel keel of wall.

(3) The door leaf soft package does not need to be a bottom plate, and the next working procedure is directly carried out.

3, the overall positioning, elastic line:

According to the design requirements, such as decorative framing, modeling, etc. , on the installed floor for hanging straight, set square, find rules, elastic line control, etc. After the drawing size is combined with the actual size, the design framing and modeling will be reflected on the floor or door leaf of the wall and cylinder according to the ratio of 1: 1.

4, lining and precast mosaic construction:

(1) When making prefabricated embedded soft bags, make lining plates according to the played control lines and paste the lining materials. Liners should be selected according to the design requirements. If there is no requirement in the design, 5mm environmental protection multi-layer board should be adopted, and the material should be cut according to the size of the played frame line. When making, a circle of battens should be nailed around one side of the liner with hard edges. The specifications and chamfer forms of battens should be determined according to the design requirements. When there is no requirement in the design, the batten shall generally be not less than 10* 10mm, with a chamfer of not less than 5*5mm, with rounded corners or inclined surfaces. The battens should be treated with oil seal to prevent the logs from discoloring and polluting the cloth. The thickness of the slats should also be determined according to the thickness of the lining material. The lining board with soft edge and flat seam can be cut according to the size. After the liner is completed, it should be pasted on the wall first to determine whether its size is correct, whether the parting is straight, and whether the height of the batten is consistent and smooth. Then take it off and number it on the back of the lining board, mark the installation direction, and paste the lining material on the front. The material and thickness of lining material should be selected according to the design requirements. If there is no requirement in the design, the material must be rent-fired and environment-friendly, and the thickness should be greater than10 mm. The lining material of hard edge flat-fell seam should be cut according to the actual net size of the inner side of the batten nailed on the lining board, and the periphery must be seamless with the batten, and the height should be higher than the batten 1-2mm, and it should be uniformly pasted on the lining board with environment-friendly glue. The lining of soft edge flat-fell seam should be cut and cut according to the size of the lining board, and the periphery must be cut and pasted neatly, flush with the edge of the lining board, and finally pasted on the lining board with environmental protection glue.

(2) When paving and wrapping doors directly, the wall joinery decoration and framing should be completed, and the painting operation is basically completed, which basically meets the handover conditions. Then cut the lining according to the played line, and then stick the lining directly on the floor or door leaf. The surface of the lining material laid must be smooth, and the joints must be straight and tidy.

5, surface construction

(1) The color, texture and texture of masked fabric and artificial leather must meet the design requirements, and the same fabric must be used in the same place. Before the fabric is covered, the front and back, texture and direction of the fabric must be determined. In the case of vertical placement, the latitude and longitude lines of the fabric should be vertical and horizontal. All fabrics used in the same place must have the same texture direction, especially pile fabrics, and more attention should be paid. The fabric should be stretched and ironed before covering the wall.

(2) Sheltering and installation of prefabricated inlaid lining boards: when the fabrics have patterns and patterns, they are wrapped first, and then the adjacent lining boards are aligned and cut according to the numbers and patterns. Fabric cutting is determined according to the size of the lining board. After the plant fabric is cut, it should be stretched and ironed first, then covered with the attached lining, and fixed from the back of the lining with U-shaped air nails and adhesive. When covering the fabric, first fix the upper and lower sides (that is, the warp direction of the fabric), and then fix the other two sides after the four corners are folded in half. Covered lining board fabric should be tight and wrinkle-free, the texture should be smooth and straight, and the fabric tightness of each lining board should be consistent. Finally, inspect the lining plates wrapped with fabric one by one, and install them according to the lining plate number after confirming that they are qualified. After the trial installation is confirmed to be correct, fix it on the bottom plate of the wall by nailing (that is, brush glue on the back of the lining plate, and then use mosquito-repellent incense nails to pass through the gap of the cloth pattern, paying attention to the air nails not to interrupt the fabric fibers).

(3) Construction of directly paving soft covers for doors and windows: According to the bounced frame lines and design shapes, determine the positioning points of fabric frame, and cut the fabric according to the positioning dimensions. When cutting, pay attention to the fact that the patterns and patterns of two adjacent fabrics must match. Cover the cut fabric on the door leaf or wall with lining material. After adjusting the position of the lower end and sides, fix the upper end with wooden strips first, and then fix the lower end and sides. After fixing around, if layering or decorative nails are required by design, nail layering according to design requirements, and then fix them with anodized hat head nails or other plum blossom-shaped decorative nails. When wooden battens are used in the design, they must be painted and polished first, and then installed on the wall after they basically survive.

6. Trimming and trimming: clean the exposed fabric fibers at the seams and edges, and adjust the seams that are not straight. Open and trim the installation holes of various equipment, install side strips, install face sticking or decoration, repair the nail holes on each batten, repair the paint on the batten and side strips, and finally wipe off the floating ash.

7. Finishing other finishes: After the soft installation is completed, the wooden frame, wall surface and other surfaces of the door leaf around it should be painted or finished for the last time, so as to make the whole indoor decoration effect complete and tidy.
