In the process of designing the aluminum alloy metal roof system, we should pay attention to its safety, functionality, building image and environmental protection, etc. In this paper, we first analyze the safety of the four elements of the aluminum alloy metal roof system, hoping to help the related construction projects.
1.Construction aspects:
Structural factors generally refer to the mechanical properties of aluminum alloy metal roofing systems, namely, compressive capacity and wind pull resistance. The compressive capacity of the roof panel can be calculated according to its section, but the overall bearing capacity is not the compressive capacity of the roof system. The compressive capacity of the roof system is also related to the strength of the roof fixed support connection points and the stability of the system. The wind pulling force of the roof system is directly related to the conditions of the roof panels, fixed support joints and occlusal joints.
2.Structural aspects:
Structural factors generally refer to the connection form and waterproof structure of aluminum alloy metal roof panels. In a long time ago, the main use of ordinary lock screws to fix the roof, and later slowly appeared a pile of nitrogen is not exposed, and these methods are not perfect in many aspects, and the use of the current support bite roof system is more common. The aluminum alloy metal roof plate is occluded between the bracket, which is connected to the structure by screws. Because the support in the system is closely connected with the roof board, the above problems are not only avoided, but also the learning force of the roof board substrate is well reduced, and the economy of the roof board is improved.
3.Waterproofing:
The waterproof performance of the roof system is directly related to the drainage performance and self-waterproof performance of the roof system. Under normal circumstances, the drainage energy of aluminum alloy metal roofing system is greatly affected by the slope of roof and the height of roof plate crest. The main factors to be considered in the self-waterproof performance of the roof system are the connection form of the aluminum alloy metal roof plate and the treatment method of the supporting system.
4.Auxiliary devices:
In order to ensure the normal use of aluminum alloy metal roofing system, the corresponding auxiliary structure should be well set according to different building characteristics and use environment, so as to keep the roof meeting the requirements of safety, function and image. The main auxiliary devices commonly used are: snow shielding, snow melting, wind protection, lightning protection and maintenance devices.
