Latching structure for roof plate

Abstract

The invention discloses a buckling structure for roofing boards, and aims to provide a buckling structure with excellent windproof performance which buckles roofing boards firmly. The roofing board disclosed by the invention comprises a soleplate (1), a first buckling part (2), and a second buckling part (3). Two adjacent roofing boards are connected through the first buckling part (2) and the second buckling part (3). The first buckling part (2) comprises a first vertical side (21), a coronary head (23), and an inward curved buckle (24). The inward curved buckle (24) is curved toward the interior of the coronary head (23). The second buckling part comprises a second vertical side (31), a transverse side (32), a third vertical side (33), and a retroflex bevel edge (34). The head of the inward curved buckle (24) leans against the transverse side (32) and the third vertical side (33). One side of the inward curved buckle (24) leans against the retroflex bevel edge (34). The invention can be widely applied to the field of buildings in steel structure.

Description

Fastening structure of roof panels technical field The invention relates to a fastening structure of building roof panels. Background technique With the development of science and technology, various modern buildings are displayed in front of people, such as glass walls, metal packaging and so on. At present, many new buildings use metal plates as roof surfaces, that is, metal sheets are used to replace traditional roofing materials. Especially in the past 30 years, with the development of building metal materials and their processing and coating technology, metal roofing has become The dominant form of ground-floor non-residential buildings. This kind of roof has the characteristics of light weight, high strength, good thermal insulation performance, good durability and good waterproof performance. At the same time, it can play a certain shielding effect on the entire building and prevent the weak current system in the building from being interfered by other external sig...

AI Technical Summary

Problems solved by technology

The existing fastening structure has poor ability to resist wind pressure. When the wind blows, the negative pressure generated on the upper surface of the roof panel will easily cause the buckle to be released, making the connection of the roof panel unstable and causing instability.
