Abstract
Description
Technical Field
[0001] The utility model relates to the field of steel structure buildings, in particular to a novel TPO fusion plate building eaves waterproof structure. Background Art
[0002] As a building system with a high degree of industrialization, steel structure buildings have been widely used in industrial buildings, but the material anti-corrosion problem is the key to affecting the performance of steel structure buildings. The overlap position of the roof and the gutter is an important node for building drainage, and the waterproofness and sealing are the key points to determine the anti-corrosion of steel structure buildings.
[0003] At present, the overlap between the roof panels and the gutters of existing steel structure buildings often has the following problems: if the fused roof panels are directly fixed to the purlins by self-tapping screws, when the temperature changes significantly, the roof panels will be subjected to temperature stress, which will cause the roof panels to curl or tear, affecting the waterproof effect and sealing performance of the roof panels. Therefore, the existing roof panel installation technology will shorten the service life of the metal roof panels and cannot effectively improve the waterproof level of the fused roof panels. Utility Model Content
[0004] In order to solve the technical problem that if the fused roof panel is directly fixed to the purlin by self-tapping screws, when the temperature change is obvious, the roof panel will be subjected to temperature stress, which will cause the roof panel body to curl or tear, thereby affecting the waterproof effect and sealing performance of the roof panel, the utility model provides a new TPO fusion board building eaves waterproof structure.
[0005] The utility model is implemented by the following technical scheme: a new type of TPO fusion board building eaves waterproof structure, including two main bodies of a fusion board roof and a fusion gutter, the two connected roof panel bodies are arranged in sequence along the width direction, the crest of the roof panel body is pasted with a crest cover, the end of the roof panel body extends outward along the long side direction to be flush with the inner wall of the gutter, and the eaves cover is used to cover the overlap between the eaves of the roof panel body and the inner wall of the gutter. According to the material properties of the waterproof base pad and the eaves cover, they are fixed by hot air welding. This method uses the physical heating and welding of the eaves cover to fix the end of the roof panel, so that the entire roof panel body and the gutter are connected as a whole. This utility model greatly improves the waterproof effect and sealing performance of the roof eaves, and at the same time strengthens the wind resistance of the roof eaves position.
[0006] As a further improvement of the above solution, the inner wall of the gutter is completely covered with a layer of waterproof base pad, which is beneficial to improving the waterproof performance of the gutter.
[0007] As a further improvement of the above scheme, a wave crest waterproof base pad is pasted on the wave trough of a single roof panel body, and the overlapping position of the roof panel body is covered with a roof wave crest cover sheet, so that the outer surface of the roof panel body is fully covered by the wave crest waterproof base pad, which is beneficial to improving the overall waterproof performance of the roof.
[0008] As a further improvement of the above scheme, the eaves cover plate is integrated with the outer surface of the fused roof panel and the inner wall of the gutter by hot air welding. This method completely seals the eaves, reduces the rust caused by the direct exposure of the inner side of the roof panel body, and improves the waterproofness and service life of the metal roof panel.
[0009] As a further improvement of the above scheme, the eaves position of the roof panel body is fixed by covering it with an eaves cover, which reduces the perforation rate of the roof panel body and the use of roof installation accessories. The entire metal roof system and drainage gutter, under the action of the waterproof base pad and the eaves cover, improves the waterproof level of the steel structure building and enhances the wind resistance of the roof eaves position.
[0010] Compared with the prior art, the beneficial effects of the present invention are:
[0011] 1. The utility model fixes the end of the roof panel by physically heating and welding the eaves cover plate, so that the entire roof panel body and the gutter are connected as a whole. This utility model greatly improves the waterproof effect and sealing performance of the roof eaves, and at the same time strengthens the wind resistance of the roof eaves.
[0012] 2. The utility model can fix the roof panel and strengthen the wind resistance of the roof eaves by pasting the eaves cover plate at the eaves position. On the other hand, it can reduce the number of perforations of the roof panel and eliminate the damage of the roof panel and the studs under the shear stress. The closed state of the eaves can prevent rainwater, wind, sand and gravel from penetrating from the eaves joints, and improve the waterproof tightness of the roof panel surface.
[0013] 3. The utility model fixes the roof eaves through a waterproof base pad, which can increase the plastic deformation capacity of the roof panel when the roof panel is affected by temperature, effectively reduce the extrusion of the roof panel due to temperature stress caused by thermal expansion and contraction, and extend the service life of the metal roof panel.

The two connected roof panel bodies 4 are arranged in sequence along the width direction, and the crest cover sheet 5 is pasted at the crest of the roof panel body 4. The end of the roof panel body 4 extends outward along the long side direction to be flush with the inner wall of the gutter 2. The eaves cover plate 1 is used to cover the overlap between the eaves of the roof panel body 4 and the inner wall of the gutter 2. According to the material properties of the waterproof base pad 3 and the eaves cover plate 1, they are fixed by hot air welding. This method uses the physical heating and welding method of the eaves cover plate 1 to fix the end of the roof panel, so that the entire roof panel body 4 and the gutter 2 are connected as a whole. This practice greatly improves the waterproof effect and sealing performance of the roof eaves, and at the same time strengthens the wind resistance of the roof eaves position.
[0023] Reference Figure 3 The inner wall of the gutter 2 is completely covered with a layer of waterproof base pad 3, which is beneficial to improving the waterproof performance of the gutter 2.
