Description

Technical Field

[0001] This utility model relates to the field of roof panel technology, and more specifically, to a screw-concealed roof panel. Background Technology

[0002] Roof panels are boards that can directly bear the roof load. They are located on the roof of a building and are generally made of metals such as aluminum, magnesium, manganese, or alloys. After the roof panels are assembled on the gable beams of the top floor of the building, the flanges overlap to cover the individual box-shaped roof panels, preventing vertical seams from being exposed to light and forming a well-integrated pitched roof.

[0003] With the widespread application of new building materials, technologies, and processes, laminated roof panels are widely used due to their advantages such as light weight, fast construction, good airtightness, strong performance, economy, aesthetics, and applicability. For example, Chinese utility model patent application number CN201320519878.7 discloses a laminated roof panel overlapping structure. However, the above solution uses screws for fixing, and the screws are directly exposed, which affects the integrity after installation. At the same time, rainwater can easily penetrate through the screws, resulting in the disadvantage that the joints are more prone to rust. Utility Model Content

[0004] The main objective of this invention is to provide a screw-concealed roof panel to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A screw-concealed roof panel includes a main body of the panel and inner and outer retaining edges integrally bent on both sides of the main body of the panel. The outer retaining edge is integrally provided with a horizontally extending bottom plate away from the main body of the panel. After the inner and outer retaining edges are interlocked, the horizontally extending bottom plate is located below an adjacent panel.

[0006] Preferably, the inner edge is formed by bending to create a positioning bending recess and a pressing bending portion.

[0007] Preferably, the outer edge is formed by bending in sequence to form a positioning bending protrusion, a limiting and tightening recess, and a horizontally extending bottom plate. The positioning bending protrusion is inserted into the positioning bending recess, and the tightening bending part is inserted into the limiting and tightening recess.

[0008] Preferably, the horizontally extending base plate is provided with at least one limiting ridge extending along the length direction of the main body of the plate.

[0009] Preferably, the edge of the abutting bend is provided with a limiting flange, which abuts against one side surface of the limiting ridge.

[0010] Compared with the prior art, the present invention has the following beneficial effects: This utility model uses nails to fix a horizontally extending base plate to the roof to complete the installation of the roof panel. Then, another roof panel is used to overlap with the inner and outer edges of the current roof panel. The main body of the panel can cover the fixing point to hide the screws. The positioning bending protrusion is inserted into the positioning bending recess for positioning the two roof panels during splicing. The clamping bending part is inserted into the limiting clamping recess to further strengthen the fixing effect. At the same time, the clamping end of the clamping bending part adopts an arc-shaped bend, which allows the inner edge to have a certain deformation, making it easy to clamp into the limiting clamping recess. The roof panel installation is more convenient, the screws are not exposed, the integrity of the laid surface is guaranteed, and it effectively waterproofs and prevents water ingress and corrosion problems at the bolt contact points.

[0013] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0014] like Figures 1-4As shown, a screw-concealed roof panel includes a main body 1 and inner and outer retaining edges 2 and 3 integrally bent from both sides of the main body 1. The outer retaining edge 3 has an integrally formed horizontally extending base plate 303 away from the main body 1. After the inner retaining edge 2 and the outer retaining edge 3 are interlocked, the horizontally extending base plate 303 is located below an adjacent main body 1. The horizontally extending base plate 303 can be fixed to the roof with nails to complete the installation of the roof panel. Then, another roof panel is used to overlap with the inner retaining edge 2 and the outer retaining edge 3 of the current roof panel. The main body 1 can be used to cover the mounting area to achieve the effect of concealing the screws.

[0015] The inner edge 2 is formed by bending to create a positioning bending recess 201 and a pressing bending portion 202.

[0016] The outer edge 3 is formed by bending in sequence to form a positioning bending protrusion 301, a limiting and tightening recess 302, and a horizontally extending base plate 303. The positioning bending protrusion 301 is inserted into the positioning bending recess 201 to position the two roof panels during splicing. The tightening bending part 202 is inserted into the limiting and tightening recess 302 to further strengthen the fixing effect. At the same time, the tightening end of the tightening bending part 202 adopts an arc-shaped bend, so that the inner edge 2 can have a certain deformation, which makes it easy to be inserted into the limiting and tightening recess 302.

[0017] The horizontally extending base plate 303 is provided with at least one limiting ridge 304 extending along the length of the main body 1 of the plate. The edge of the abutting bending part 202 is provided with a limiting flange 203. The limiting flange 203 abuts against one side surface of the limiting ridge 304. The limiting flange 203 can be used to tightly insert the abutting bending part 202 into the limiting abutting recess 302 to prevent the overlapping part from loosening.

[0018] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
