Concealed works of new house decoration

  • Detail

Finding out some hidden works of new house decoration is of great benefit to improving the quality of decorated houses. Otherwise, if it is ignored, it will bring the trouble of continuous cutting and chaos

the so-called "concealed works" are construction projects that are concealed after decoration and cannot be seen on the surface. According to the decoration process, these "concealed works" will be covered by the next process, so it is difficult to check whether the materials meet the specifications and whether the construction is standardized. Concealed works refer to the works laid inside the decorative surface

1. Water supply and drainage works

galvanized pipes will be phased out because they are easy to rust, scale, do not keep heat, and will freeze. At present, plastic aluminum composite pipe, plastic steel pipe and PPR pipe are used most. 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

2. Electrical pipeline engineering

general power lines are divided into hard lines, flexible lines, sheathed lines, etc. according to the thickness of copper core, they are also divided into 1 mm2 line, 1.5 mm2 line, 2.5 mm2 line... For the sake of safety and easier maintenance, the power line should be sleeved. In addition, there are commonly used audio lines, signal lines, etc. Sockets are divided into 10a, 15a, etc. there are also many brands and many fake ones. Inferior sockets are easy to cause accidents. It is recommended to buy them in regular electrical appliance stores. Electrical circuit engineering requires standardized construction, and workers should work with certificates to ensure safety and eliminate hidden dangers

3. Floor base

solid wood floor base has two methods: one is to brush cold primer oil on the cement floor once, 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. In this way, 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

4. Parapet base course

parapet board has flat type and concave convex type. The method is to brush a layer of cold primer oil on the wall first, then install 30mm*40mm wood 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

5. The base course of door and window sleeves

first arrange the keel, then nail the blockboard or density board, and nail the wood line with the veneer plywood on the surface. Notice that the density board should be soaked in water to avoid expansion in the future

6. Ceiling base

ceiling 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 completion of concealed works, acceptance is required to ensure that there are no hidden dangers, and subsequent construction can be carried out only after it is qualified. Otherwise, problems found in the future will need to be reworked, which will not only affect the quality, but also delay the construction period
