Description

Technical Field

[0001] The utility model relates to the technical field of building engineering, in particular to a wind-resistant connection structure of a decorative metal plate on a roof. Background Art

[0002] Conventional roof decorative metal plate connection form is a two-layer connection. The first layer: the aluminum alloy angle code is connected to the metal plate through rivets. The second layer: the angle code is placed on the roof frame and then fixed to the roof frame through self-tapping screws or machine nails. Finally, the roof frame is fixed to the main structure.

[0003] The pull-out resistance of self-tapping screws or machine-made nails has a certain risk of wind-lifting in strong typhoons; self-tapping screws or machine-made nails are directly fixed, and cannot adapt to the displacement of the plate and frame caused by temperature deformation, resulting in uneven decorative board surface and affecting the appearance. Moreover, the reliability of self-tapping screws or machine-made nails during installation depends on the installation level of on-site workers. The installation level and installation speed will affect the degree of thread engagement and thus weaken the overall wind resistance to a certain extent. Utility Model Content

[0004] The purpose of the utility model is to provide a wind-resistant connection structure for decorative metal roof panels in order to overcome at least one of the defects of the above-mentioned prior art, which effectively solves the problem of directly fixing the metal decorative panels to the keel to limit the thermal expansion and contraction of the decorative panels, thereby solving the problem that the surface of the decorative panels becomes uneven with the increase of use time.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0011] The pressing block, the connecting assembly and the keel are mutually abutted in sequence, and the three are fixed by the bolt shaft screwed into the threaded hole of the pressing block. Among them, the metal decorative plate can also be any form of decorative plate with fasteners. The pressing block fixing the decorative plate will not limit the thermal expansion and contraction phenomenon of the decorative plate under the lighting of the roof, and can ensure that the plate surface is smoother.

[0012] Furthermore, the connection assembly includes an auxiliary frame and an angle code connector; the auxiliary frame is fixedly connected to the metal decorative plate; the angle code connector is L-shaped, one end of which is fixedly connected to the auxiliary frame, and the other end is arranged between the pressing block and the keel.

[0013] Furthermore, the auxiliary frame is connected to the metal decorative plate by welding; the corner code connector is connected to the auxiliary frame by welding or threading.
