In fact, in home decoration, in order to select clean accessories or contractors, they should visit the decoration site. Even if they have already invited the decoration supervisor, they should go to the scene and look at the construction process and check the construction process. Workers' attitude towards work. Even if you don't understand it, it doesn't matter. I've listed some of the common field knowledge here.
Decoration site
As the saying goes, the insiders are looking at the door and the amateurs are watching. Especially the decoration, the construction process involves the laying of circuits, waterways and other complex hidden projects, most of the owners to the construction site often have a feeling of being unable to intervene, I do not know what to pay attention to?
One: decoration ceiling
The combination of ceilings and floor slabs and keels and veneers is not good, or the load-bearing weight is too large, which can easily cause "falling off."
According to the regulations, the ceiling keel can not be distorted and deformed. The installed keel should be firm and reliable. The horizontal deviation must not exceed 5mm. The chandelier or ceiling fan exceeding 3 kg in weight cannot be hung on the ceiling keel, but a separate hook should be provided. If the ceiling is made of gypsum board, the thickness should be about 9mm.
II: Decoration waterproof
Waterproofing is a covert work that is part of the home improvement process. Waterproofing is very important, because cities are now buildings. If water seepage occurs, not only will they have to be re-installed, but it will also affect the downstairs. The acceptance of waterproofing, of course, is to do a 24-hour closed water test, to ensure that the qualified waterproof case can be used for the next construction.
III: Wall and Keel
If the wall and keel violate the rules of operation, it will not be easy to find. For example, due to the collapse of the ceiling as a whole or in part, the ceiling becomes a "top drop."
Four: other small knowledge
1, the line does not have insulating tube
During construction, the line is buried directly in the wall. The conductor is not covered with an insulating tube, and the line connector is directly exposed. There are hidden dangers: This is very unsafe, and may cause a short circuit in the line after it is damaged due to a certain reason, such as the aging of the line; at the same time, once the line is broken, the line cannot be changed, and only the wall knocks on the ground.
Regulatory operation: The line must be laid with insulation bushings on the outside. At the same time, 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.
2. It is arbitrarily dismantled and changed the waterway. Under the circumstance that the owner does not understand the decoration, the owner is misled to dismantle the waterway at will 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.
3, strong and weak electricity placed together
Typical jerry cuts. Strong power? Such as lighting lines and weak electricity? If a telephone line or a network line is placed in a tube or in a box, a tube is placed less, saving 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.
4, the length is not enough without connection accessories
Because the length of the insulating tube is not enough, there is exactly a turn here, no connection fitting is placed, and a section is exposed at the junction with the junction box.
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.
5, the number of wiring
Because the decoration line price is calculated according to meters, a large number of repeated wiring, multi-use 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.
6, the line tube is damaged by the follow-up project
Typical barbaric construction. 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.
7. 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 line inside the threading pipe is liable to spark and fire.
Putty when the cement is used to make a rough 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.
Standard operation: The cement used to plug the trunking must be the same as the cement of the original structure to ensure its strength.
8, the line is not separated
All lines use a single 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.
9, water pipe mixed problem
White is a cold water pipe, red is a hot water pipe, and a cold water pipe and a hot water pipe 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.
10, the use of glue problems
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.
