The so-called hidden project refers to the part of the concrete situation that people are hidden from the surface after the decoration, and people can't see it from the surface. In recent years, with the repeated problems in the renovation and concealment projects, people have become more and more unsightly Pay attention, what are the specific parts of the hidden project, and what issues should be paid attention to when constructing the hidden construction project?
First, what is the hidden project
Concealed works refer to projects that need to be covered or covered by foundations, electrical pipelines, and water supply and heating pipelines. According to the renovation process, these "hidden projects" will be covered by the next process, so it is difficult to check whether the materials meet the specifications and whether the construction is normative.
What are the hidden works in home improvement?
The hidden works for home decoration mainly include six aspects: water supply and drainage engineering, electrical pipeline engineering, floor base layer, wall covering base layer, door and window cover base layer, ceiling base layer.
III. Precautions for Construction Acceptance 1. Water Supply and Drainage Engineering As galvanized pipes are prone to rust, fouling, non-insulation, and freezing, it will be phased out. At present, the most used are plastic aluminum composite pipes, plastic steel pipes and PPR pipes. These tubes have good plasticity and toughness, and the insulation does not crack or foul. The use of special copper joints or thermoplastic joints guarantees quality assurance and low energy consumption.
2. The general power line of electrical pipeline project is divided into hard line, soft line, sheath line, etc. According to the thickness of copper core, it is divided into 1 square millimeter line, 1.5 square millimeter line, 2.5 square millimeter line... For safety reasons, it is more convenient For maintenance, the power cord should be sleeved. In addition there are audio lines, signal lines and so on. Sockets are divided into 10A, 15A,... There are many brands, too many counterfeits. Poor outlets are prone to accidents, and it is recommended to purchase them in a regular electrical appliance store. Electrical wiring projects require construction regulations. Workers should hold certificates to ensure safety and eliminate hidden dangers.
3, floor base
There are two approaches for the base of solid wood flooring: brushing cold base oil on cement floors, laying wooden keels, and finally nailing floors; another method is to lay a layer of blockboard on the keel first, or a wool floor, and then nail Floor, using this method, the floor is evenly distributed and the structure is firm. Composite floors are easy to install and there are also two ways to do this: one is to make the leveling layer first, then lay the PVC cushion, and then lay the composite floor; the other is on the cement leveling layer, laying the wooden keel and the wool floor, and the two-storey composite floor.
4, retaining wall base wall panels are flat and bump type. The practice is to brush a layer of cold base oil on the wall first, then install a 30mm*40mm wooden keel, nail the multilayer board or blockboard on this basis, and finally nail the veneer plywood. In order to prevent mildew, a series of 6mm diameter courageous holes are opened on the upper part of the visor.
5. Doors, windows, doors, base layers The keels are arranged first, then the wood panel or the density board is nailed, and the surface is plywood nailed to the surface. Note that the MDF should be soaked in water to prevent it from expanding in the future.
6, ceiling base ceiling materials are gypsum board, gray board, plywood, aluminum alloy pinch, plastic pinch, milled glass, stained glass, keel wood keel and light steel keel. Cracking of ceilings often occurs, such as the use of elastic putty joints, and the application of nylon straps can improve this situation.
Xiao Bian concludes: We introduced the construction acceptance of concealed works for everyone. We hope to help everyone. For more relevant knowledge, please continue to pay attention to this website information platform. Follow-up will present more exciting content for everyone.
