Description
Technical Field
[0001] The utility model relates to the technical field of building roof waterproofing, in particular to a ridge cover plate anti-leakage structure, which is used for preventing the installation of ridge cover plates of roofing projects from leaking. Background Art
[0002] Waterproofing the roof of a lightweight steel factory building is a key consideration for the quality of the roof panel installation. To prevent roof leaks, the ridge of large-span factories requires trimming. A water barrier is typically installed between the ridge cap and the roof panel. Roof panels are typically constructed from composite corrugated steel sheets, which are rolled using a press. The corrugated surface significantly increases flexural rigidity and offers advantages such as fast construction, light weight, high performance, and excellent airtightness. However, this also presents a common problem: roof leaks.
[0003] During the traditional construction of corrugated steel sheet roofs, ridges, eaves and other parts are often sealed with plugs made of steel plates or foam plastic plugs (water retaining boards). The material properties of the steel plate plugs themselves are greatly affected by the environment, temperature, etc. After thermal expansion and contraction, the integrity of the sealant and the steel plate is poor, which can easily cause gaps and leakage.
[0004] Therefore, there is an urgent need for a structure that can improve the anti-leakage performance and overall stability of the roof system and reduce the possibility of leakage at the connection between the ridge cover plate and the roof panel. Utility Model Content
[0005] The technical problem to be solved by the utility model is to provide a ridge cover plate anti-leakage structure, which improves the anti-leakage performance and overall stability of the roof system and solves the common problem that the ridge cover plate is prone to leakage.
[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:
[0007] A ridge cover plate anti-leakage structure includes a roof panel and a ridge cover plate, a butyl rubber plug is provided at the connection between the ridge cover plate and the roof panel, a butyl sealing tape is pasted below the butyl rubber plug, the outside is wrapped with a water retaining plate, and a Z-shaped metal gusset plate is provided on the top; the Z-shaped metal gusset plate includes an upper wing plate, a lower wing plate and a web plate vertically arranged between the upper wing plate and the lower wing plate, wherein the upper wing plate and the lower wing plate are located on opposite sides of the web plate; the upper wing plate is arranged between the lower end of the ridge cover plate and the upper end of the water retaining plate, and the butyl rubber plug is pressed and fixed by upper self-tapping screws passing through the ridge cover plate, the upper wing plate and the water retaining plate; the lower wing plate is connected to the ridge plate at the top of the wave crest on the inner side of the roof panel through lower self-tapping screws.
[0008] A further improvement of the technical solution of the present invention is that: the ridge cover plate is arranged on the expansion joint between the two roof panels; the ridge cover plate includes a top plate and a bottom plate inclined downward, and the bottom plate of the ridge cover plate is arranged along the entire length of the roof panels; an extension plate inclined downward is provided on the outer side of the bottom plate of the ridge cover plate.
[0009] A further improvement of the technical solution of the present utility model is that the overlapping length of the ridge cover plate and the Z-shaped metal gusset plate is not less than 200 mm.
[0010] A further improvement of the technical solution of the present utility model is that two layers of weather-resistant glue are applied between the water retaining plate and the roof panel for sealing.
[0011] A further improvement of the technical solution of the present utility model is that the butyl rubber plug is further designed according to the roof panel shape in combination with BIM technology, and BIM modeling is performed on the butyl rubber plugs in various parts.
[0012] A further improvement of the technical solution of the present utility model is that the thickness of the butyl rubber plug is 50 mm.
[0013] A further improvement of the technical solution of the present utility model is that: the roof panel is a corrugated roof panel.
[0014] A further improvement of the technical solution of the present utility model is that the butyl sealing tape is a butyl waterproof tape.
[0015] A further improvement of the technical solution of the present utility model is that the water retaining plate is a cold-bent profile.
[0016] A further improvement of the technical solution of the present utility model is that both the upper self-tapping screws and the lower self-tapping screws are waterproof rivets.
[0017] Due to the adoption of the above technical solution, the technical progress achieved by the present invention is:
[0018] 1. The utility model is designed in depth according to the roof panel type combined with BIM technology, and BIM modeling is performed on the butyl rubber plugs in various parts of the roof panel. Butyl sealing tape is pasted under the butyl rubber plugs, and the outside is wrapped with a water retaining plate. A Z-shaped metal gusset plate is arranged on the upper part to be connected to the roof panel through the lower self-tapping screws, and the butyl rubber plugs are pressed and fixed on the ridge cover plate through the upper self-tapping screws. The upper self-tapping screws pass through the ridge cover plate, the Z-shaped metal gusset plate, and the water retaining plate and are driven into the butyl rubber plugs without passing through the roof panel.

[0032] Furthermore, the ridge cover 5 is installed on the expansion joint between the two roof panels 9. The ridge cover 5 includes a top plate and a bottom plate that slope downward. The bottom plate of the ridge cover 5 extends along the entire length of the roof panels 9. An extension plate is installed on the outer side of the bottom plate of the ridge cover 5. Specifically, the lower end of the bottom plate of the ridge cover 5 contacts the upper end of the upper wing plate of the Z-shaped metal gusset plate 1, and the lower end of the upper wing plate contacts the upper end of the water retaining plate 8 (which is enclosed in a butyl rubber plug 2).

[0034] Furthermore, two layers of weather-resistant glue 3 are applied between the water retaining plate 8 and the roof panel 9 for sealing.
[0035] Furthermore, the butyl rubber plug 2 is further designed according to the plate shape of the roof panel 9 in combination with BIM technology, and BIM modeling is performed on the butyl rubber plug 2 in each part, that is, the butyl rubber plug 2 can fill the gap at the connection between the roof panel 9 (including the peaks and troughs) and the ridge cover plate 5.
