The hidden works in home decoration refer to the pipeline engineering and structural engineering concealed inside the decorative surface. Pipeline engineering includes electrical circuit, water supply and drainage, gas pipeline, and air conditioning system; structural engineering refers to the internal structure used to fix and support the load of the house. Although once fabulous beasts and high-tech factions exposed the structure of the pipeline as beautiful, this method is not suitable for the decoration of ordinary people.

The project acceptance should be noted that, of course, the leakage of the waterproof project can not occur.
In the first step, the acceptance personnel set up a 15 cm high retaining wall at the entrance to the room for acceptance;
In the second step, we put 10 centimeters of water in the room, and at the same time, we must mark the height of the water.
In the third step, after 24 hours, the inspectors checked whether the height of the water surface had changed, and at the same time checked whether the ceiling of the room at the same position in the downstairs had seepage.
In the fourth step, if the above phenomenon does not occur, the acceptance personnel can think that the acceptance of the waterproof construction is qualified; conversely, if the above phenomenon is found through inspection, the construction of the waterproof project can be considered as unqualified. If the acceptance is unqualified, the waterproof project must be reworked and re-inspected; for the acceptance of the light-weight wall waterproof construction, the water-drenching test shall be adopted, even if the water pipe is on top of the waterproof paint wall. Discontinuity spray for 3 minutes. After 4 hours, observe whether the other side of the wall will have a seepage phenomenon. If there is no penetration phenomenon, it can be considered that the wall waterproof construction is qualified.
Tip: For the first step of the ground work, we often say that the closed water test; due to the light wall is prone to leakage, and the routine inspection of this part is easy to omit, so I gave the reader a Small idea.
The inspection and acceptance of distribution engineering and the acceptance of waterproofing projects are to prevent leakage of water. The acceptance of distribution is to make the line unobstructed, and no short circuit or open circuit occurs. The inspection personnel should check the following items in order:
1, whether the various materials used meet the design requirements;
2. Is the line tube fixed?
3, whether the line pipe connection is firm;
4ã€Whether the wires have joints and joints are firm;
5, whether there is a connector for the TV cable, if any connector must be replaced, or use a disassembler at the connector;
6. If there is a connector on the telephone line, if any connector must be replaced;
7, whether the cassette is installed Founder, whether in the required height;
8. Whether the construction team makes marking on the site where the line pipe is laid;
9, whether the position of the cassette is reasonable, whether the line tube is reasonable, and whether the position of the line connector is reasonable.
Tip: There is one point that should be noticed in the acceptance of power distribution, that is, the problem of the ground line, the construction personnel should arrange the ground line according to the construction process.
Floor wood keel installation acceptance
1. Check whether the specifications of wood keel meet the design requirements (generally not less than 2 cm × 3 cm);
2. Check whether the spacing of the wooden keel meets the requirements for the installation of wooden floors (each floor requires at least two keels);
3, check whether the wooden keel loose phenomenon (can step on a step);
4. Check if the plane on the wooden keel is flat (use 2 meters by the ruler);
5. Check whether the gap between the wooden keel and the ground is replaced with a wood wedge instead of a wooden block;
6. Check whether the length of the nails used in the fixed wooden keel can meet the requirements of long-term use, and no loose phenomenon will occur;
7, check whether the high-grade installation meets the design requirements;
8. Check whether there is a telescopic gap at the junction of the wood keel and the wall (to avoid moisture deformation).
Tip: Some people believe that solid wood flooring is prone to deformation and its service life is relatively low. However, if it meets the above acceptance requirements, the service life will be greatly enhanced.
Acceptance of wall ceiling scraper
1, check the putty surface is dry (the putty does not dry, if you brush the paint, it is prone to cracking phenomenon);
2. Check the surface of the putty for cracks (crack must be treated in time);
3, check whether the putty surface is flat;
4, check putty surface is smooth;
5. Check the wall surface and the wall surface, and whether the wall surface and ceiling are straight forward;
6. Check whether there is any unclear boundary between the wall surface and the wood products (if the putty is hung on the wood products, it will affect the appearance quality of the wood products).
Tip: There is a problem with the construction quality of the wall putty, which will affect the construction of the paint, and it will also affect the future use of consumers.
Acceptance of upper and lower water construction
1. Check whether the water pipes and fittings meet the requirements of customers (if possible, use good quality water pipes and plumbing fittings);
2. Check whether the direction of the water pipe is reasonable, whether there are too many corners, too many joints;
3, check the hose is dead bent, the connection distance is greater than 1 meter (the hose connection distance should be as short as possible);
4. Check for leaks at all joints (visual inspection or use of soft white paper);
5, check the hose is installed at the door (to prevent the water pipe can not be replaced after cracking);
6, the inspection of the water is to take the drainage method.
