Description

Technical Field

[0001] The invention belongs to the technical field of metal roof improvement, and in particular relates to a waterproof and heat-shrinkage-proof structure around a metal roof panel structural column and an installation method. Background Art

[0002] Metal roofs are widely used in industrial plants and public buildings due to their low cost, convenient shaping, efficient construction, and beautiful appearance. For some special requirements such as thermal insulation, heat insulation, and fire protection, they are often filled with certain special chemical materials between multiple layers of metal plates to achieve the purpose, with good results.

[0003] Since metal roofs need to be spliced ​​piece by piece during the laying process, and their construction is often carried out separately from the construction of the wall, especially in some buildings with non-metallic exterior walls, the overlap between metal roof panels, the connection between metal roofs and walls, and the connection between metal roofs and drainage systems are all very critical. One of the most critical factors affecting such buildings is the rainproof performance of metal roofs after installation. With the actual operation of a large number of construction projects and the application of various technologies, the rainproof performance of conventional metal roofs has basically achieved good results in terms of technology and theory, which mainly depends on the installation quality.

[0004] However, the waterproofing of the roofs of some buildings with special functional requirements such as structural columns that extend beyond the roof is particularly special. Such buildings often have special functions and have high requirements for waterproofing. Therefore, when encountering such buildings, designers usually do not use metal roofs, but traditional cast-in-place roofs for waterproofing. When encountering a building roof with a certain shape or other requirements that requires the use of metal roof tiles, a built-in gutter drainage form is often set to solve the series of problems it faces, such as drainage, heat shrinkage, and aesthetics.

[0005] As time goes by and due to objective factors such as material aging, built-in gutters often leak after several years of use, or the drainage capacity cannot meet the actual situation, resulting in the risk of water leakage inside the building.

[0006] The limitations of the above methods make it difficult to fundamentally solve customer demands, or may cause the building to face certain risks of water leakage. Summary of the invention

[0015] In another embodiment, the other end of the bottom steel plate is fixedly connected to the second supporting purlin by a fourth rivet.

[0016] As a preferred solution, the bottom steel plate is a spherical raised structure at the joint with the second rivet.
