In order to meet the needs of their own personal decoration, the owners often make some structural changes to the original room to be renovated. However, both the decoration company and the owner should know that the following structural changes are not allowed, or must be approved by the relevant competent authorities:
1. Demolition or modification of load-bearing structures, such as the removal of load-bearing walls, the expansion of the original door and window dimensions on the load-bearing walls, and the removal of bricks and concrete walls connecting balconies;
2. Change the facade of the house and open doors and windows on non-load-bearing walls;
3. Demolition of gas pipelines and facilities;
4. Demolition of heating pipes and facilities;
5. Build buildings and structures;
6. Change the room or balcony without waterproof requirements to the bathroom and kitchen.
If the decoration company has the above-mentioned behavior during the demolition project, it can only be dealt with by the unqualified project when the quality of the interior decoration project is accepted. Therefore, readers who wish to prepare for decoration should be careful not to arbitrarily change the structure of the building or to make unreasonable demands for the demolition project to the decoration company. At the same time, we also hope that the decoration company will take the initiative to explain the situation to the owners and avoid disputes in the future.
The acceptance of the quality of concealed works of hydropower hidden projects is very important. It is the intrinsic quality of the entire residential renovation and must not be ignored. Owners can check the following requirements if they are not required to be tested by professional personnel. If necessary, leave a written record for the record.
The water supply pipeline is usually installed by the decoration company and the supplier shall be responsible for the installation. The supplier shall use the equipment for pressure leak detection and issue a certificate of inspection. The certificate shall be kept by the decoration company. At the end of the renovation, other materials, such as the actual direction of the pipeline Maps, etc., are handed over to the owner for retention. The fixing of the water supply pipes and valves is secure.
Wires should be laid with PVC pipe, and the total cross-sectional area of ​​the wire should not be greater than 40% of the PVC pipe (for example, 2.5 square millimeters of the six-way pipe can only be used for four wires). The wires must not be worn with telephone lines, cable television lines, and network cables. One tube. PVC pipe wall thickness is 1.2 mm or more, and the hand grip should not feel soft and not broken. Wires, hot water pipes, and gas pipes shall be kept in close proximity to each other and shall not abut.
The discharge of electric wires should be taken away from the wall. It should not be carried out under the floor, under the floor tiles or at high altitude. The position of the switch should be 130 centimeters from the ground, and the position of the socket should be about 20 centimeters from the ground.
The wire on the suspended ceiling shall not be placed on the keel, and the junction box, lamps and ceiling fans shall not be fixed on the keel, and the keel shall be fireproofed. The size of the keel shall meet the load-bearing requirements of the ceiling.
The decoration company shall submit the actual drawing of the wire and water pipe to the owner for preservation. At present, a considerable part of the decoration company does not provide the customer with the actual drawing of the pipeline, which brings great inconvenience to the maintenance of the owner in the future. The wooden joists should be dry, and the ground floor houses should also be protected from moisture on the ground and wooden joists, but it is forbidden to use asphalt as a moisture-proof treatment. After the wood joist is leveled, it must not be fixed with a wedge plug. The fixing of the wooden joists should use hammer-type special expansion nails, or use a nail and a screw, not only a nail or a screw. Floor noise, wooden joists laying a non-standard accounted for a considerable proportion.
In short, the family decoration must not underestimate the quality of hidden projects. If conditions permit, it is still necessary for professionals to check.
