Lap joints and bridging joints are two key parts of water leakage. Compared with reinforced concrete roofs, the gutter depth of steel structure roofs is small, and there is no continuous waterproof structure between gutters and roofs. water leakage. The main reasons for water leakage at this part are: there are gaps in the welding joints of the inner gutter, causing water seepage; the design of the gutter and rainwater pipe diameter is too small, which does not match the slope length of the factory building; there is no head plate at the end of the gutter; If the length of the gutter is not enough, the water will flow back into the factory building.
The main reasons for water leakage in this part of the steel structure factory building are: improper handling of the interface between the awning and the attached room; no plug is installed between the awning and the outer wall or it is not extended into the outer wall panel according to the design requirements.
The waterproofing of the lighting panel is an important part of the maintenance system waterproofing. The cement laying and waterproof screws in the installation of the lighting panel are the main hidden dangers of roof leakage; the shape of the lighting panel does not match the shape of the roof panel, and the peaks on both sides of the lighting panel are higher than the roof panel After installation, the air pressure difference between the inside and outside of the lighting board is too tight, and the capillary water leaks into the roof from the gaps on both sides of the lighting board; the longitudinal lap length of the lighting board is not enough, and the glue loses its viscosity due to aging; There is a rigid overlap between them, and the gap in the middle is not sealed.
This part is easy to form a hidden danger of water leakage. Water leakage occurs at the joint between the roof panel and the cement wall. The main reason is that the stress is not synchronized, which causes the bonding surface between the structural wall and the steel plate to crack and cause water leakage.
The connection between the aluminum alloy window and the color steel wall and the brick wall is one of the waterproof problems. The main reasons for the leakage of this part are: there is a gap between the wall purlin and the aluminum alloy; the lower opening of the window and the steel structure, the brick wall and the window The seal between the glass and the profile is not tight; there is a large gap between the window sill and the platform or there is water back; the window top is not waterproof during the installation of the flashing edge.
The above is SAFS Steel Structure Space Frame Company’s specific analysis of the causes of water leakage in the factory building. I believe that after understanding it, it can bring substantial results to your project. If you have any relevant questions, please leave me a message below.
