Invisible hidden dangers in home improvement concealed projects

Right now, the weather is dry and it is a season of high decoration. Many new home buyers scrambled for the construction period and rushed to stay in the renovated house for the Spring Festival. The reporter visited found that due to the mixed materials of decoration materials and the quality of decoration workers, the sequelae caused by the decoration of the house often make the owners irritated.

Renovators reminded that compared to the visible minor repairs, many “invisible” hidden projects, such as waterproofing, circuit laying, etc., are not handled well, and the latter repairs are often large projects, and even need to chisel the walls. Therefore, in the home improvement, the quality of the “invisible” project should arouse the attention of the decoration owner.

Hidden troubles in repairing and repairing often require "chiseling a brick wall"

Recently, Miss Lin, who has been in the renovated house for just over two years, has been busy with the after-effects of the renovation. Because the bathroom was not properly waterproofed, a grayed-out wall was peeling off in a room adjacent to the bathroom. “The small repairs are not helpful. They need to open all the tiles in the bathroom and then re-waterproof them. Then they must be tiled for three or four days at the fastest.” The decoration company gave such advice. Since the whole family has already lived in, this kind of reloading directly affects the family's life.

Visits found that there are not a few encounters like Miss Lin. Problems such as seepage, wall cracking, and falling off of ceilings are not uncommon in the two or three years after the renovation. Among them, the phenomena of water-proof engineering and circuit installation problems are at the top. Fang Hui, a designer of the decoration company, introduced that in the construction of a lot of materials, many construction workers used cost-effective 1.5-millimeter square lines for grounding. In the event of a real circuit failure, the load was not enough. Some workers cut corners and connected to the dark lines, which are prone to oxidation short-circuiting. The repair of circuit faults is a very large project. Some non-standard companies do not even have circuit distribution plans.

In the process of renovation, the method of repairing failures of “invisible” projects such as water and electricity, in addition to the comprehensive treatment of the chiseled floor tiles, is currently not a very good solution.

Avoiding: Doing a Recessive Engineering Construction Supervision

So how do you avoid invisible hazards? Recently, the reporter visited a number of decoration companies in Foshan to provide a method for evading the hidden dangers of home improvement for the owners of new houses to be renovated.

Water hazard avoidance

Kitchens and toilets are the two major sources of household water and must be watched for waterproofing. Due to the serious water vapor in the bathroom, the waterproof work around the wall is a top priority. It is understood that the current waterproof material is generally no problem, the most important is the construction supervision. Some workers do not use matching ratios in accordance with the specification, and unevenness in the brushing of waterproof materials will result in poor waterproof performance. It is worth mentioning that the waterproofing of bathroom walls cannot be tested by the method of testing water, and special attention should be paid.

Second, the interface and layout of the water pipes are also not sloppy. After completion of the water pipe connection, the water should be checked. If conditions permit, it can be pressure tested as much as possible.

However, air-conditioning drainage is the most easily overlooked. Air-conditioning drainage is as simple as possible, easy to check, and there should be a certain slope from top to bottom to facilitate drainage. At the same time, the drain should not be too long, not to go through places such as wardrobes that require high moisture protection.

Circuit hazard avoidance

The hidden dangers of the circuit are mainly reflected in whether the wiring is reasonable and the packet line is not suitable for connection. To ensure the hidden dangers of the circuit, it is necessary to plan the room's electricity demand in advance. Especially for equipment that consumes large amounts of electricity, such as air conditioners, it is necessary to plan or reserve sufficient lines in advance.

There are several problems in the circuit that cannot be ignored. One is that the packet line cannot be connected; the other is that the wires should be properly categorized in the live line, neutral line, and ground line; the third is that the size of the wire must meet the demand of the power equipment. General use of 2.5 square millimeters of wire, and air conditioning, electric water heaters and other high-power electrical lines should use 4 square mm wire; Fourth, pay attention to the wire casing, should not be filled with wires, in order to avoid the use of high-power electrical appliances can not lead to heat dissipation Short circuit. It is generally required that the cross-section of the wire does not exceed 40% of the cross-section of the bushing; the fifth is that the strong and weak wires should not be put in the same bushing, and the two should be separated by 50 cm to prevent the weak signal of the TV circuit from being disturbed.
