Description

Technical Field

[0001] The utility model belongs to the field of assembled structural module buildings, in particular to a quick-assembly steel structural module building roof installation structure. Background Art

[0002] Steel-structured modular buildings are becoming increasingly popular due to their advantages, such as factory prefabrication, on-site installation, short construction periods, and reliable quality. This is especially true for temporary structures such as emergency relief and shelters, which require a large number of lightweight, easily disassembled and reusable modular products suitable for various application scenarios. However, modular buildings currently have a large number of joints, especially those in the top roof units, which are mostly sealed with local welding of steel components, making the top modules difficult to remove and reuse. Other existing technologies use steel components with waterproofing mortar, tape, and other methods to treat joints. While this solves the problem of removal and reuse, the roof's anti-aging and waterproofing properties are poor due to exposure to sunlight and deformation. The use of integral roofs also brings with it problems such as heavy overall weight, the need for large lifting equipment for installation, high requirements for construction personnel, and slow construction speeds.
