Key points of acceptance of concealed works of dec

  • Detail

The acceptance of concealed works of decoration mainly includes decoration waterway, circuit, waterproof, balcony heightening, ceiling, guarantee, etc., which shall be participated in by the customer, decoration project supervisor and decoration construction person in charge. The construction can be continued only after the decoration acceptance is qualified and signed

concealed works in home decoration refer to pipeline works and structural works concealed inside the decoration surface. Pipeline engineering includes electrical circuit, water supply and drainage, gas pipeline, air conditioning system, etc; Structural engineering refers to the internal structure used to fix and support the load of the house. Although the once popular Fauvism and high-tech school took exposing the pipeline structure as the beauty, this method is not suitable for the decoration of ordinary people's homes

it is worth noting that at present, the quality problems of concealed works of decoration are widespread, and many hidden dangers are left due to inconvenient maintenance. Therefore, it is necessary to understand its structure and materials. The concealed works of home decoration mainly include six aspects:

1, floor base. There are two ways to decorate the base of solid wood floor: one is to brush cold primer oil on the cement floor, lay wooden keel, and finally nail the floor; Another method is to lay a layer of blockboard or rough floor on the keel, and then nail the floor. With this decoration method, the floor is evenly stressed and the structure is firm. The installation of composite floor is convenient, and there are two methods for the base: one is to make a leveling layer first, then lay PVC cushion, and then lay composite floor; The other is to lay wooden keel and rough floor on the cement leveling layer, and two composite floors

2. Electrical pipeline engineering. Generally, the power lines for decoration are divided into hard lines, flexible lines, sheathed lines, etc., and are divided into 1 mm2 lines, 1.5 mm2 lines, 2.5 mm2 lines according to the thickness of copper cores. For the sake of safety and easy maintenance, the power line should be sleeved. In addition, there are commonly used audio lines, signal lines, etc. Sockets are divided into 10a, 15a, There are also many kinds of brands and many counterfeits. Inferior sockets are easy to cause accidents. It is recommended to buy them in regular electrical appliance stores. For electrical circuit engineering, it is required that the construction of decoration should be standardized, and workers should work with certificates to ensure safety and eliminate hidden dangers

3. Water supply and drainage works. Galvanized pipes will be phased out because they are easy to rust, scale, do not keep warm, and freeze crack will occur. At present, plastic aluminum composite pipes, plastic steel pipes and PPR pipes are used most in decoration. These pipes have good plasticity and toughness, and the insulation does not crack or accumulate dirt. Special copper joints or thermoplastic joints are used, with quality assurance and less energy consumption

4. The base course of the retaining wall and the decoration of the retaining wall board are flat and concave convex. The decoration method is to brush a layer of cold primer oil on the wall first, then install 30mm*40mm wooden keel, nail multi-layer board or Blockboard on this basis, and finally nail veneer plywood. In order to prevent mildew, a series of pores with a diameter of 6mm are opened on the upper part of the parapet during decoration

5. Door and window sleeve base course. First arrange the keel, then nail the blockboard or density board, and nail the wood line with the veneer plywood on the surface. Note that the density board should be soaked in water in advance to avoid future expansion

6. Ceiling base. Ceiling decoration materials include gypsum board, gray board, plywood, aluminum alloy gusset, plastic gusset, ground glass, painted glass, etc. the keel is divided into wood keel and light steel keel. Ceiling cracks often occur, such as caulking with elastic putty and sticking nylon bandages, which can improve this situation

after the concealed works of decoration are completed, they need to be accepted to ensure that there are no hidden dangers, and the subsequent decoration construction can be carried out only after they are qualified. Otherwise, problems found in the future will need to be reworked, which will not only affect the quality of decoration, but also delay the construction period. Both the owner and the decoration contractor will suffer losses
