Several points of waterproofing of steel structure factory roof

The construction technology of steel structure houses is a systematic project, in which the performance of the waterproof construction quality of the metal roof is not only related to the service life of the workshop, but also affects its use function. The reasons for the penetration and waterproofing technology of the steel structure factory roof should be carefully analyzed and studied.

There are several reasons for the penetration of the steel structure factory roof:

In the design stage of the roof waterproofing project, if the roof drainage slope is not properly designed, it will cause difficulties in the roof waterproofing, which is not conducive to the roof waterproofing. Drainage, when there is a lot of rainfall, the waste water on the roof will accumulate, and it will be too late to discharge, which will corrode the roof and reduce the waterproof ability of the roof. The scientific and reasonable design of the roof drainage system can prevent the occurrence of water seepage and water leakage and prolong the service life of the steel structure workshop. The roof drainage design must have a certain slope, and it is necessary to ensure that there are enough downpipes to combine leakage prevention and drainage to complement each other and quickly remove rainwater from the roof.

At present, the roof waterproofing materials used by domestic steel structure housing manufacturers have improved in technology and quality, but their waterproof performance still does not meet the standard of roof waterproofing. The material is easy to crack at low temperature, melted at high temperature, has poor water resistance and short life. In some construction projects, due to the influence of climate and poor quality waterproof materials, some projects see water as soon as they are completed. In addition, the problem of roofing materials is also a prominent problem in the waterproofing of steel structure workshops. Now there are new products of waterproof materials on the market, especially waterproof membranes, which account for more than 85% of waterproof materials. However, designers do not understand the performance and use environment of these new waterproof materials, so they will be affected by environmental factors and reduce the waterproof effect of the materials.

During the construction process, improper mixing ratio of roofing concrete, improper vibrating or insufficient maintenance in the later period will easily cause cracking of concrete, and the shell of the waterproof layer will cause the roof to penetrate. If there is a roofing membrane, due to careless construction and sloppy details of the structure, it will cause water seepage and water leakage. In order to improve the construction quality, we must pay enough attention to ensure that the quality of the steel structure house meets the standard and prolong the service life of the building surface of the steel structure factory.

For roof waterproofing, it must be strictly required in terms of design, construction and maintenance materials to ensure that each link can meet the quality requirements. All in all, as long as we pay attention to the construction details, use a suitable roof waterproofing system, and arrange for an experienced and qualified construction team to construct, we can effectively prevent and solve the problem of roof leakage.
