Description

Technical Field

[0001] This utility model relates to the field of roof waterproofing technology, specifically a leak-proof structure for steel structure metal roof skylights. Background Technology

[0002] With the rapid development of society and economy, steel structure buildings are widely used due to their advantages such as wide application range, lightweight construction, convenient manufacturing, fast construction speed, and low carbon footprint. Currently, waterproofing of steel structure metal roofs remains a challenge, and roof skylights are a weak link in waterproofing design and construction. Improving the anti-leakage capability of metal roof skylights plays a crucial role in enhancing the quality of steel structure buildings.

[0003] Existing technologies for various skylights and metal roofing products have relatively mature and complete systems and techniques. However, when skylights are installed on metal roofs, the integrity of the roof is inevitably compromised due to the openings. A common solution is to install flashing at the connection point, with one end fixed to the skylight base and the other to the roof panel. However, in actual use, due to various factors such as deformation of different materials under temperature, aging of sealant, and inadequate joint construction, leakage problems often occur at the connection between the metal roof and the skylight, allowing rainwater to seep directly through the joint. Therefore, there is an urgent need for a steel structure metal roof skylight waterproofing structure to solve these problems. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide a leak-proof structure for steel structure metal roof skylights to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A steel structure metal roof skylight leak-proof structure includes: a skylight, the bottom of which is connected to a skylight base, the skylight being connected to a skylight flashing, the skylight base being connected to the top of the roof flashing, the roof flashing being located between the skylight flashing and the skylight base, the bottom of the roof flashing being connected to the top of a C-shaped connector, and the bottom of the C-shaped connector being connected to a metal roof panel.

[0007] As a further embodiment of this utility model: the end of the metal roof panel near the C-shaped connector has an upward-curved structure.

[0008] As a further embodiment of this utility model: the skylight base is connected to the top of the roof flashing by self-tapping screws.

[0009] As a further embodiment of this utility model: the bottom end of the roof flashing is connected to the top of the C-shaped connector by rivets, and the bottom of the C-shaped connector is connected to the metal roof panel by rivets.

[0010] As a further embodiment of this invention, the end of the rivet is sealed with sealant.

[0011] As a further embodiment of this utility model: the C-shaped connector has an asymmetrical structure, with its short side connected to the bottom end of the roof waterproofing board and its long side connected to the upward-curved metal roof panel.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model, through the design of a C-shaped connector, avoids the metal roof panel and the roof flashing being connected by perforations at the same location. The C-shaped connector indirectly connects the metal roof panel and the roof flashing, preventing rainwater from directly leaking through the connection point after the sealant ages. At the same time, the buffer space formed by the C-shaped connector also prevents rainwater from leaking into the house to a certain extent, greatly improving the water-proof effect at the skylight joint.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] In this embodiment of the utility model, please refer to Figure 1 A steel structure metal roof skylight leak-proof structure includes: a skylight 3, the bottom of which is connected to a skylight base 1, the skylight 3 is connected to a skylight flashing 4, the skylight base 1 is connected to the top of a roof flashing 6, the roof flashing 6 is located between the skylight flashing 4 and the skylight base 1, the bottom of the roof flashing 6 is connected to the top of a C-shaped connector 8, and the bottom of the C-shaped connector 8 is connected to a metal roof panel 2.

[0018] The roof flashing 6 is connected to the skylight base 1 to form a whole. The end of the metal roof panel 2 is bent. One end of the C-shaped connector 8 is connected to the metal roof panel 2, and the other end is connected to the roof flashing 6. Waterproofing is achieved through the skylight flashing 4, the roof flashing 6, and the metal roof panel 2. The C-shaped connector 8 indirectly connects the metal roof panel 2 and the roof flashing 6 to avoid perforating the metal roof panel 2 and the roof flashing 6 at the same location, thus preventing rainwater from directly leaking from the connection point.

[0019] As one embodiment of this utility model, please refer to Figure 1 The end of the metal roof panel 2 near the C-shaped connector 8 has an upward-curved structure, which can prevent rainwater from entering the C-shaped connector 8 and then leaking into the house through the metal roof panel 2.

[0020] As one embodiment of this utility model, please refer to Figure 1 The skylight base 1 is connected to the top of the roof flashing 6 by self-tapping screws 5.

[0021] As one embodiment of this utility model, please refer to Figure 1 The bottom end of the roof flashing 6 is connected to the top of the C-shaped connector 8 by rivets 7, and the bottom of the C-shaped connector 8 is connected to the metal roof panel 2 by rivets 7; the ends of the rivets 7 are sealed with sealant.

[0022] The joints between rivet 7 and roof flashing 6, rivet 7 and metal roof panel 2, and rivet 7 and C-type connector 8 are sealed with sealant to ensure waterproof sealing effect.

[0023] As one embodiment of this utility model, please refer to Figure 1 The C-type connector 8 has an asymmetrical structure, with its short side connected to the bottom end of the roof waterproofing board 6 and its long side connected to the upward-curved metal roof panel 2.

[0024] The working principle of this utility model is as follows: the roof flashing 6 is connected to the skylight base 1 with self-tapping screws 5 to form a whole. The end of the metal roof panel 2 is bent up. The C-shaped connector 8 is connected to the metal roof panel 2 at one end with rivets 7 and to the roof flashing 6 at the other end. The end of the rivet 7 is sealed with sealant to improve the sealing effect. The C-shaped connector 8 indirectly connects the metal roof panel 2 and the roof flashing 6. Even if the sealant ages and leakage occurs at the rivet 7, the rainwater will be blocked by the buffer space created by the C-shaped connector 8 and the bent metal roof panel 2, preventing rainwater from directly leaking from the connection between the two and greatly reducing the risk of leakage.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
