What problems in the design and construction of residential containers can cause water leakage?

The residential container is a kind of temporary building that is widely used now. It is recognized by people because of its convenient and quick installation and disassembly, energy saving and environmental protection, and flexible movement. What is the cause of the leak? In fact, the reason for the water leakage is caused by both design and construction. Today Wellcamp will take you to understand.

1. Design aspects

1. During the design of the roof rainwater system for residential containers, overflow measures were not set up in accordance with the requirements of the specification. Therefore, after the rainwater exceeds the discharge capacity of the system, the phenomenon of rainwater flowing over the lap joints may occur, resulting in the phenomenon of residential containers The roof has leaks. In particular, the roof connected with concealed buckles and nailed boards is more likely to have serious water leakage.

2. The purlins on the roof of the residential container have design defects that the section is too small and the spacing is too large. Therefore, under the action of wind load, the purlins and profiled plates are seriously deformed, and there are structural defects, which will lead to the roof. There is a problem of stagnant water.

3. There are no detailed design drawings for the edging of the upper and lower cornices of the window, the flashing board of the roof and the yin and yang corners, so that the inexperienced construction team cannot carry out strict construction, so there will be hidden dangers of water leakage.

Second, construction

1. The quality of gutter welding is not good enough, the material anti-corrosion treatment is not in place, and the insulation measures of the gutter are not done well, which will cause the leakage of the gutter. In addition, the temperature difference in summer is relatively large, which is also prone to condensation.

2. The key nodes in the construction of the residential container are not constructed according to the regulations, or the details are not handled properly, such as the short side end of the coil is not tightly sealed, the fixing points are scarce, the catchy white iron sheet is deformed, and the sealing The material is not tightly sealed, and there is no dark whistle at the inner corner of the root of the wall to make an arc or the arc is too small, thus causing leakage of the roof.

3. The wall purlins of the living container are not straight enough, there is a gap between the window frame, or there is a problem with the sealing under the window and between the steel structure and between the window glass, which will also cause panning above the window. There is water seepage in the water parts, and there is water storage under the eaves of the windows.

The above are some of the problems that are likely to cause water leakage in the design and construction of residential containers. After understanding the causes of water leakage, it is necessary to avoid these problems as much as possible when designing and constructing residential containers. Completely eliminate the hidden danger of water leakage.
