Renovation and acceptance must be divided into three steps to covert projects as key

The acceptance of decoration is divided into three stages: initial stage, middle stage, and late stage, and the acceptance items in each stage are different. Especially the acceptance of the hidden project in the middle stage is very important for the overall quality of home decoration.

Initial acceptance of decoration acceptance

The most important thing in the initial acceptance is to check whether the incoming materials (such as putty, glue, etc.) are consistent with the materials on the budget sheet of the contract, and in particular, whether the brands of the hydropower reform materials (electric wires, water pipes) belong to the special brand of the decoration company. Inclusion of other materials in the incoming materials affects the later construction.

If the owner finds that the incoming material is different from the brand in the contract, he can refuse to sign the material acceptance form until he negotiates with the decoration company and signs again.

General renovation can be carried out about 15 days for mid-term acceptance (villa construction time is relatively long), the mid-term acceptance is divided into the first acceptance and the second acceptance. The first acceptance involves items such as ceilings, water circuits, and wood products, and the second acceptance is specifically for the inspection of rooms that are waterproof. Therefore, the medium-term project is the most complicated step in the renovation and acceptance. The acceptance of the project will affect the performance of multiple renovation projects in the later period.

Ceiling: Acceptance ceiling should first check whether the wooden keel of the ceiling is coated with fireproof material, followed by inspection of the spacing of the boom. The distance between the boom cannot be too large or it will affect its bearing capacity. The spacing should be between 600mm-900mm. Again, check the stability of the boom and see if it is rocking. The boom should be fixed with expansion bolts. Some of the foremen use woodbolts for cost savings and it is difficult to guarantee the stability of the boom. The boom must be fixed with expansion bolts in the vertical direction and plastic bolts in the transverse direction. Finally, the flatness of the keel should be checked by means of a pull wire.

Waterway reconstruction: The test of the waterway reform is mainly to conduct pressure test. When the pressure is applied, the pressure should not be less than 6kg. The pressure can not be less than 15 minutes. Then check whether the pressure gauge has pressure relief. If there is pressure relief, check the valve. Close, if there is a problem of pipeline leakage, immediately notify the foreman and treat the leaking condition of the pipeline before proceeding to the next step.

Circuit Modification: When accepting the circuit, it must be noted whether the wire used is the brand of the decoration company and whether the wire is up to standard. The non-compliance of wires has the condition of thin blister cores or coarse copper cores. These two non-compliant wires have an impact on the current load, which leads to potential safety problems for the owners in future use.

When checking the circuit modification, check the closed condition of the socket. If the original socket has been displaced, carry out moisture-proof and waterproof treatment at the shifting position, and apply a waterproof tape over 3 layers for sealing. Also check that the circuit joints in the ceiling are also treated with waterproof tape.

Wood products: For wood products produced on site, first of all, it should be noted whether the shape of the wood products meets the design requirements and the dimensions are accurate. The wood doors produced on site should also be checked for the reasonable opening direction of the doors. The door joints above and below the wooden door can not exceed 3mm, and the bottom joints are generally 5-8mm. In addition to viewing the door joints, it is also necessary to check whether the joints of the door covers are tight.

Wall tiles, floor tiles: Walls and floor tiles are mainly used to check their emptying rate and color difference. The owner can use a small hammer to beat the corners of the wall and floor tiles to check for empty drums. The emptying rate of walls and floor tiles cannot exceed 5%, otherwise it will fall off. It is worth noting that the walls and floor tiles are not allowed to have hollows in the middle. The mortar is not full, the grassroots is not properly handled, and the time for the tiles is insufficient may cause hollowing in the middle of the tiles. If the middle hollows appear in the tiles, the owner should ask the foreman to Some tiles are eradicated and re-sticked.

When checking the color difference, pay attention to whether the brand of the tile is the same, whether it is the same batch number and whether it is paved at the same time. The owner can also check the aesthetic appearance of the wall and floor tiles. Under normal circumstances, seamless bricks and bricks are sewn around 1.5mm, which cannot exceed 2mm, and tile bricks with radian edges are about 3mm. In addition, you should also check whether there are missing corners in walls and floor tiles.

Wall surface, top surface: Acceptance wall surface, the top surface should check the flatness of the putty, you can use the ruler to check, the error is within 2-3mm as qualified. Owners should pay special attention to whether the yin and yang angles are square and straight when they are inspecting the wall surface and the top surface.

If the owner finds a problem during the mid-term acceptance, he shall immediately report to the supervisor for rectification. After the rectification is completed, the supervisor shall notify the owner of the re-acceptance.

Waterproof: Waterproof acceptance is another highlight of mid-term acceptance. In general, rooms with floor drains will be waterproofed. Whether or not waterproof is in place not only affects the daily lives of the owners, but also affects the interests of the owners downstairs. The water-repellent test is a common method of testing waterproofing in home improvement. When conducting the avoidance test, the foreman needs to confirm the time of avoidance with the owner and the occupants downstairs at the same time, and then close the drain hole of the room to put the water into the room (water level Not less than 3cm. After 24 hours, ask the owner of the downstairs if there is leakage.

In addition to checking the waterproof of the floor drain room, the owner should also check the waterproof of the shower wall. When inspecting the waterproof wall, you can check whether the paint on the wall is uniform and there is no brushing phenomenon. In particular, check whether the yin and yang angle leak brush. To avoid yin and yang leakage brush causing moldy mildew.

The waterproof height of the wall is also subject to acceptance. Upon acceptance, the owner can check whether the waterproof height of the wall has reached the height promised by the company. Generally, the waterproof height of the shower is about 1.8m, but from an economic point of view, the owner can take a shower. The area is set to a height of 1.8m and the other areas are set to a height of more than 1.5m.

Acceptance acceptance of the end of acceptance

The acceptance at the end of the period is relatively simple compared to the mid-term acceptance. It mainly tests the closing part of the medium-term project. Such as wood products, wall surface, top surface, the owner can test the smoothness of its surface paint, paint, whether there is flow phenomenon and the color is consistent.

The circuit mainly checks whether the wiring of the socket is correct and whether the power is on, and the socket of the bathroom should be provided with a waterproof cover.

The inspection of the waterway reform is still the focus. The owner needs to check whether there is a "back slope" in the room where there is a floor drain. The inspection method is very simple: open the tap or shower, and after a certain period of time, see whether the flowing water is smooth and whether there is local water accumulation. In addition, the smoothness of the floor drains, the toilet and the wash basin should be checked.

In addition to the acceptance of the last part of the medium-term project, the owner should also accept the renovation projects at the end of the floor, plastic steel window, etc. When inspecting the floor, you should check whether the color of the floor is the same, whether there is any warping or noise. Acceptance plastic window, you can check the edge of the plastic window is left with 1-2cm gap filled with styrofoam. In addition, the solidity of the steel window should also be checked. Under normal circumstances, every 60-90cm should be hit with a bolt to fix the plastic window. If the fixing bolt of the plastic window is too small, the use of the plastic window will be affected.

There is also a problem that should be paid attention to, such as whether the pipelines of the kitchen and the bathroom are left with inspection and backup ports, and whether the water meters and gas meters are easily accessible for reading.
