AI Technical Summary
Metal roofs of large factory buildings are prone to leaks due to deformation, and existing technologies are insufficient to effectively prevent rainwater from seeping into the interior, especially for buildings storing valuable equipment where rain protection is required.
Expansion joints are installed on the metal roof, filled with thermal insulation cotton, and fixed to the purlins through inner edge trim and outer cover plate to form a Z-shaped structure, which is then sealed with self-tapping nails and butyl tape.
Even after the metal roof deforms, it can still effectively prevent rainwater from entering the room, providing long-term rain protection and ensuring the safety of indoor equipment.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal roofing technology, specifically a rainproof device for metal roofs. Background Technology
[0002] Currently, most large factory buildings use metal roofs, and leakage is a persistent problem. Conventional metal panels are prone to deformation, allowing rainwater to seep into the interior through the deformed areas. Large factories store valuable equipment and therefore have high requirements for rain protection. This application aims to solve the problem of leaky metal roofs. Summary of the Invention
[0003] In view of the above-mentioned prior art, this utility model proposes a rainproof device for metal roofs.
[0004] This utility model provides a metal roof rainproof device, comprising:
[0005] Expansion joints are installed on metal roofs; the interior of the expansion joints is lined with thermal insulation cotton.
[0006] The inner edge is provided on the metal roof and is located at the lower end of the expansion joint;
[0007] An outer cover plate is installed on the metal roof and located above the expansion joint; both sides of the outer cover plate are fixedly connected to the metal roof via purlins.
[0008] Preferably, the width of the expansion joint is 100mm.
[0009] Preferably, the inner edge is configured as a V-shaped structure.
[0010] Preferably, the purlin has a Z-shaped structure.
[0011] Preferably, both sides of the inner edge are fixedly connected to the metal roof using self-tapping screws.
[0012] Preferably, the outer cover plate is fixedly connected to the purlin by self-tapping and rotating screws, and the periphery of the self-tapping and rotating screws is sealed with butyl tape.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model proposes a metal roof rainproof device, which can be used for a long time after construction. Even after the roof is deformed, it can still effectively prevent rainwater from entering and has a high degree of protection for indoor equipment. Attached Figure Description
[0014] Figure 1 This is a schematic diagram of the structure of the metal roof rainproof device in the embodiment of this utility model.
[0015] In the diagram, 1 is an expansion joint; 2 is a metal roof; 3 is thermal insulation; 4 is an inner edge trim; 5 is a self-drilling screw; 6 is an outer cover plate; 7 is a purlin; and 8 is a self-drilling screw. Detailed Implementation
[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0017] Example: Figure 1 The illustrated metal roof rainproof device includes an expansion joint 1, which is provided on the metal roof 2; the expansion joint 1 is 100mm wide and is filled with thermal insulation cotton 3 to prevent the metal roof 2 from leaking due to deformation.
[0018] The inner edge 4 is fixed to the metal roof 2 and located at the lower end of the expansion joint 1. The inner edge 4 is set as a V-shaped structure. Both sides of the inner edge 4 are fixedly connected to the metal roof 2 by self-tapping screws 5.
[0019] The outer cover plate 6 is fixed to the metal roof 2 and located at the upper end of the expansion joint 1. Both sides of the outer cover plate 6 are fixedly connected to the metal roof 2 via purlins 7. The purlins 7 adopt a Z-shaped structure. The outer cover plate 6 is fixedly connected to the purlins 7 via self-tapping screws 8, and the periphery of the self-tapping screws 8 is sealed with butyl tape. After the Z-shaped purlins 7 and the outer cover plate 6 are installed, they can effectively prevent outdoor rainwater from entering the room.
[0020] The rainproof device in this embodiment can be used for a long time after construction. Even after the metal roof 2 is deformed, it can still effectively prevent rainwater from entering and has a high degree of protection for indoor equipment.
[0021] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent solutions made using the contents of this utility model specification, whether directly or indirectly applied to other related technical fields, are also within the patent protection scope of this utility model.
