Description

Technical Field

[0001] The utility model belongs to the technical field of metal roof improvement, in particular to a waterproof and heat-shrinkage-resistant structure around a metal roof panel structural column. Background Art

[0002] With the rapid development of society, metal roofing has become widely used in industrial plants and public buildings due to its low cost, easy shaping, efficient construction, and beautiful appearance. For applications requiring special insulation, heat insulation, and fire protection, the use of special chemical materials filled between multiple layers of metal panels is often effective.

[0003] Because metal roofing is assembled piece by piece during installation, and its construction is often carried out separately from wall construction, particularly in buildings with non-metal exterior walls, the overlap between metal roof panels, the connection between the metal roof and the wall, and the connection between the metal roof and the drainage system are all crucial. A key factor affecting the performance of such buildings is the rainproof performance of the metal roof after installation. With the practical implementation of numerous construction projects and the application of various technologies, the rainproof performance of conventional metal roofs has generally achieved good technical and theoretical results, which primarily depends on the quality of installation.

[0004] However, waterproofing is particularly challenging for rooftops with special functional requirements, such as those with structural columns extending beyond the roof. These buildings often have specialized functions and demand higher waterproofing requirements. Therefore, designers typically avoid metal roofing for these types of buildings, opting instead for traditional cast-in-place roofs with waterproofing. When metal roofing tiles are required for specific aesthetics or other requirements, internal gutters are often installed to address drainage, thermal shrinkage, and aesthetic issues.

[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 buildings to face certain risks of water leakage. Summary of the Invention

[0009] As a preferred solution, the fixed purlin is fixedly connected to the second supporting purlin, the second supporting purlin is fixedly connected to the third supporting purlin, and the second supporting purlin is fixedly arranged above the first supporting purlin.

[0010] As a preferred solution, the fixed angle iron is fixedly connected to one end of the bottom supporting steel plate through a first rivet, and the other end of the bottom supporting steel plate is fixedly connected to the fixed purlin through a fourth rivet.

[0048] Example 3

[0049] According to the structure described in Example 1-2, the installation method is as follows:

[0050] S1: Fixed angle irons 13 are provided on three sides of the structural column 1. A fixed purlin 5 is provided on the second supporting purlin 3 on the front side of the structural column 1. The two ends of the front bottom steel plate 8 are connected to the fixed purlin 5 and the fixed angle iron 13 respectively. The two ends of the bottom steel plates 8 on both sides are connected to the second supporting purlin 3 and the fixed angle iron 13 respectively.

After being collected, it flows to the centralized gutter downstream for discharge; when the temperature rises or drops, the metal roof panel will expand or contract, which is reflected in the position change of the telescopic panel 7 at the structural column. Due to the expansion space reserved for the overlap with the flashing board 9, the position change of the telescopic panel 7 will not be restricted, thereby avoiding local metal fatigue damage of the telescopic panel 7 caused by the thermal expansion and contraction of the metal roof panel.
