View 1: Waterproofing Project For the hidden waterproofing project, the most important thing is to do meticulous construction. First of all, before the renovation, the construction personnel must do a 24-hour water-retaining test. After confirming that there is no leakage, clean up the ground debris, remove the loose parts, and then use a cement mortar to smooth the uneven areas, and then the entire Flattened on the large surface. Closed water test can also play a role in distinguishing and determining the responsibility of the waterproofing project. There is a leakage phenomenon responsible for the developer; there is no leakage after the renovation and there is leakage, the responsibility is in the decoration company. If the bathroom is waterproof, the water will splash on the adjacent wall when bathing. If there is no protection of the waterproof layer, the partition wall and the diagonal wall of the corner will become mildewed, so be sure to prepare the wall surface before laying the wall tiles. Waterproofing, in general, the walls are to be treated with a waterproof height of 30 centimeters, but the non-load-bearing lightweight walls should be waterproofed at least to 1.8 meters high. Special attention should be paid to the corners and strictly prevent the occurrence of drip leaks. In fact, most of the waterproof layer leaks are corners. Therefore, if these places are properly prepared, the possibility of leakage will be reduced.
View 2: wall and keel if the wall and keel violated the operating procedures are also easily found. For example, due to the collapse of the ceiling as a whole or in part, the ceiling becomes a "top drop."
View 3: The combination of the suspended ceiling and the floor slab and the keel and the veneer is not good, or the load is too large, which can easily cause a "top drop". According to the regulations, the ceiling keel shall not be twisted or deformed. The installed keel shall be firm and reliable. The horizontal deviation shall not exceed 5 mm; a chandelier or ceiling fan exceeding 3 kg in weight shall not be hung on the ceiling keel, but shall be separately provided. If the ceiling is made of gypsum board, the thickness should be about 9mm.
View 4: Fragmentation 1. The hot and cold water pipes are mixed with white cold water pipes, red hot water pipes, and the cold water pipes and hot water pipes are mixed together. There are hidden dangers: the expansion and contraction rate of hot and cold water pipes is different. Due to thermal expansion and contraction, the cold water pipes burst and leak. Standard operation: distinguish hot and cold water pipes according to color and operate strictly. 2, use 107 glue decoration 107 glue. There are hidden dangers: As the 107 glue contains toxic substances such as formaldehyde and benzene, the state has banned it. Normative operation: At present, there is no natural and pollution-free glue on the market. The substitute is 108 glue. However, we must look for better brands and look for products with test reports. 3, the wire does not have a set of insulating tube in the construction of the wire directly buried in the wall, the wire is not covered with insulation tube, wire connector directly exposed. There are hidden dangers: This is very unsafe, and may cause short-circuit of the wires due to some reasons, such as the aging of the wires, resulting in wire breakage; at the same time, once the wire is broken, it cannot be changed at all, only the wall knocks on the ground. Standard operation: The wires must be laid with insulation sleeves on the outside, and the circuit joints should not be exposed on the outside. They should be installed in the line box. No joints are allowed between the distribution boxes. 4. It is arbitrarily dismantled and changed the waterway. If the owner does not understand the decoration, he misleads the owner to dismantle the waterway and waste money.
There are hidden dangers: waste of money is only one aspect. Once it is not sealed or lacks pressure during the demolition of the waterway, it will lead to burst of water pipes. Normative operation: When the pipeline is changed, it will move and it must not be moved when it is not. 5, strong and weak electricity placed together with typical jerry cuts. Put strong electricity, such as lighting wires and weak electricity, such as telephone lines and network cables, in a tube or in a box. Shop a tube less, save time and effort. There are hidden dangers: There will be interference when making a call or surfing the Internet. At the same time, too much threading in a pipe also creates a risk of fire. Normative operation: Strong and weak electricity should be routed separately. It is forbidden to share one pipe and one bottom box for strong and weak electricity. 6, the length is not enough no connection accessories due to the length of the insulation tube is not enough, here is exactly a turn, do not place the connection accessories, at the junction with the junction box to expose a section. There are hidden dangers: If you stay for a long time, it may cause leakage due to the aging of the line. Normal operation: There should be something connected between the nozzle and the junction box. 7, repeat the wiring a large number of repetitive wiring, multi-purpose materials, waste the owner's financial and material resources. There are hidden dangers: Once a problem arises in the line, it is difficult to detect it in a layout like "Tian Luo Di Network." Normative operations: Arranged closely, in the case of no more than 40% of the capacity of the pipe, the same trending line can be worn in a pipe. However, it is necessary to separate strong and weak electricity. 8. The typical brutal construction of the line pipe damaged by the subsequent project. After the pipeline was laid, it was slotted on the ground again and the pipeline was laid through. There are hidden dangers: After you check in, you may find that there is no electricity in a room in your home. You can only detect and re-thread all the wires in your home. Normative operation: The construction cannot be performed again in the place where the pipeline is laid. If it is damaged, it is forbidden to wire in the middle when changing lines. When the circuit load is large, the joint of the wire in the threading pipe is easily sparked and a fire occurs. 9, putty when the cement with a typical crude construction. On many construction sites, the mistakes of the construction team were well-known, and the horizontal slotting did not say that after the wiring of the line pipe was completed, the putty powder was used as cement. There are hidden dangers: The horizontal slotting during the decoration has destroyed the bearing weight of the entire building, and the original design's ability to resist earthquakes has decreased. Normative operation: The cement used to plug the trunk must be consistent with the cement of the original structure to ensure its strength. 10, wire regardless of the color of all lines with a color, for the sake of labor. There are hidden dangers: once the line is in trouble, the line of discordance is detected again. Normative operation: The bottom box wire wraps are wrapped with different signs. FireWire uses red wire and red cloth, neutral wire is blue, green and black, and it is wrapped with the same kind of color wire cloth. Yellow, green and blue wires are used for ground wire.
