Description

Technical Field

[0001] This utility model relates to the field of corrugated steel structure technology, specifically, a corrugated steel plate connection structure. Background Technology

[0002] Corrugated steel structure is a new type of structural material in modern times. It has the characteristics of high strength, light weight, good ductility, strong resistance to deformation, and low load on the foundation. Moreover, it is widely adaptable to various environments and complex terrains. Corrugated plate products are quick and easy to install, have a high secondary utilization rate, relatively short construction period, low cost, and are environmentally friendly.

[0003] Based on the advantages and benefits of corrugated steel structures, they are widely used in railway, highway, municipal, water conservancy, underground pipe gallery, old bridge and culvert reinforcement, tunnel reinforcement and other projects. More and more people are replacing conventional concrete structures with new corrugated steel structures.

[0004] Corrugated steel structures are composed of multiple corrugated steel plates connected and fastened with bolts. The connection methods between corrugated steel plates are usually lap joints and flange joints. Especially when corrugated steel structures use ordinary flat flanges for internal or external connections, bolts are often used directly after the flanges are butt-jointed. In this way, all the external forces on the corrugated steel structure are transferred to the bolts, which increases the shear force on the bolts and can easily lead to damage to the quality of the project and shorten its lifespan.

One side area is fixedly connected to the corrugated steel plate, and the other side area is suspended to cooperate with the corrugated steel plate edge shear flange assembly c4 of another corrugated steel plate.

[0035] III. Working Principle

[0036] Reference Figure 3 The corrugated steel plates are connected through a corrugated steel plate connection structure. The implementation method is as follows: Corrugated steel plate 1 is the main material of the corrugated steel structure; the two ends of corrugated steel plate 1 form a circumferential shear-resistant connecting flange with corrugated steel plate end shear-resistant flange assembly a2 and corrugated steel plate connecting flange assembly b3, and corrugated steel plate end shear-resistant flange assembly b8 via connecting holes 6 and bolts 7. This effectively controls the displacement of individual corrugated steel plates, increases the overall structural resistance of the corrugated steel plate components, and greatly reduces the shear force of the bolts.

[0037] Specific reference Figure 4The T-shaped structure formed by the corrugated steel plate end shear flange assembly b b plate 8 and the corrugated steel plate end connecting flange assembly b3, together with the corrugated steel plate end shear flange assembly a2, enables the application of part of the force to the corrugated steel plate after being subjected to shear force through the horizontal plane of the corrugated steel plate end shear flange assembly b b plate 8 and the corrugated steel plate end shear flange assembly a2, thereby reducing the shear force of the bolts.

[0038] The two sides of the corrugated steel plate 1 form a longitudinal shear-resistant connecting flange of the corrugated steel structure, consisting of the corrugated steel plate edge shear-resistant flange assembly c4 and the corrugated steel plate edge connecting flange assembly d5 and the corrugated steel plate edge shear-resistant flange assembly d baffle 9. The corrugated steel plate edge shear-resistant flange assembly c4 and the corrugated steel plate edge connecting flange assembly d5 and the corrugated steel plate edge shear-resistant flange assembly d baffle 9 are connected and fastened through the connecting holes 6 and bolts 7, which effectively controls the displacement of a single corrugated steel plate, increases the overall structural resistance of the corrugated steel plate component, and greatly reduces the shear force of the bolts.

[0039] Specific reference Figure 5 The T-shaped structure formed by the corrugated steel plate edge shear flange assembly d-baffle 9 and the corrugated steel plate edge connecting flange assembly d5, together with the corrugated steel plate edge shear flange assembly c4, enables the application of part of the force to the corrugated steel plate after being subjected to shear force through the corrugated steel plate edge shear flange assembly d-baffle 9, thereby reducing the shear force of the bolts.
