There is water leakage in later use during the installation of grid structure

The use of grid architecture is more and more extensive, which is quite common in our life. Because of the beautiful appearance of grid architecture, coupled with the characteristics of large available space, less investment and fast construction of grid architecture, more and more users tend to prefer grid architecture when choosing buildings. But the vast majority of workshops, production workshops, warehouses and other buildings cover a large area, and the space span of the building is large, which leads to the phenomenon of water leakage on the roof. What is the cause?

There are many reasons for this phenomenon. The detailed analysis is as follows:

     1. Material: it is very important to choose the right type of metal roof panel. Good products can eliminate the hidden danger of water leakage to a great extent.

     2. Unreasonable design: the roof slope is too small, which is easy to cause water collection. The diameter of the sewer pipe is too small, resulting in poor water flow. The waterproof level is not enough, and the difference of rainfall in different areas is not considered.

     3. Installation is not in accordance with the specification: the joints are not properly treated. The overlapping part between the   color plates is not firm, and it seeps when the rain falls. The nail made by the color board penetrates the rubber pad and penetrates through the gap of the nail. How to make the daylighting belt and the color plate arched roof. Construction personnel trample on it at will, causing uneven and long-term rain leakage. It is easy for the color steel structure workshop to leak rain at the gutter joint of cornice, the upper and lower openings of windows, the daylighting belt of roof, the 1.2m edge of wall and the air tower.

     In addition to the above reasons, the installation of grid structure may cause water leakage if some details are not done well: 1. The plug is not added; 2. There is no water stop strip; 3. The quality of sealant is poor; 4. The specification of purlin is too small; 5. It is not used properly, for example, in windy days; 6. The lap length of roof panel is not enough, or the drainage measures are not done; 7. The gutter is too small, leading to backwater pouring, or the spacing of downpipe is not enough or the pipe diameter is too small; 8. The beam The deflection is too large to meet the specification requirements, but it does not meet the use requirements, and it is not considered at the same time with the color steel plate
