Reasons and maintenance methods of steel structure canopy leakage
The steel structure canopy is mainly to provide a shelter for the vehicle to protect the vehicle from heavy rain and exposure to the sun. The application fields of Nanjing steel structure canopy are also quite wide. In public places such as industrial plants, schools, shopping malls and other public places, various canopies for parking bicycles and electric vehicles can often be seen. Of course, there are also private rain canopies customized for cars shed. As a canopy, the most important thing is to have good rainproof performance, which is also a special concern of customers. Once the canopy is found to be leaking, the construction party will often be required to maintain it. So why does the steel structure canopy leak, and how to minimize the damage of the leak, it is necessary to find the crux of the leak. Generally speaking, there are two main factors for the rain leakage of steel structure canopy, one is caused by man-made reasons, which can be avoided in the construction, and the other is caused by the characteristics of the material itself, which is generally unavoidable. Maintenance after the fact. As far as human factors are concerned, the leakage of steel structure canopy is nothing more than unreasonable design, irregular construction and installation, and inadvertent operation of construction personnel. The unreasonable design is mainly manifested in, for example, the roof winding is too large or the slope is too slow, the water flow speed is slow, causing water accumulation, the diameter of the downspout is not satisfied, the panel selection is improper, the edge closing, the design of the gutter node is unreasonable; in terms of construction and installation , Improper handling of seams, insufficient care at joints, inadequate waterproofing materials, lax glue for closing edges, and careless installation of screws will all lead to cracks and leaks in the canopy. Therefore, everyone should find a relatively professional steel structure company to build it. E.g“Suzhou Hengguang Steel Structure Engineering Co., Ltd.”It's pretty good. There are also hidden dangers of water leakage caused by material characteristics. For example, the thermal conductivity of the metal plate itself is large. When the external temperature changes greatly, due to the large change in the ambient temperature difference, the material shrinks and deforms due to the temperature change, resulting in a large displacement at the interface. There is a hidden danger of water leakage; in the steel structure system, the structure itself is prone to elastic deformation under the action of external forces such as temperature change, wind load, snow load, etc., resulting in displacement at the connection part, resulting in hidden danger of water leakage. In order to solve the rain leakage of the steel structure canopy, it is necessary to comprehensively consider various factors such as roof slope and plate type in the design process to obtain the best solution; in the construction process, strictly abide by the construction specifications and be careful Seriously, reduce roof cracks; fully consider the climate characteristics of the area where the building is located, and adopt waterproof measures and materials suitable for the area; according to the characteristics of the material, a layer of strong adhesion, good followability and extreme weather resistance can be placed on the roof. It is the best sealing tape as a matching waterproof material for metal roof panels.
