Single bent and twisted color band and production method thereof

Abstract

The invention discloses a single bent and twisted color band, which comprises a bottom plate, transverse baffles, longitudinal webs, side plates, reinforcing bars and a face plate, wherein the transverse baffles are perpendicularly and fixedly arranged on the upper surface of the bottom plate; the longitudinal webs are perpendicularly and fixedly arranged on the transverse baffles and the bottom plate; the reinforcing bars are fixedly arranged on the front surfaces and the rear surfaces of the two ends of the side surfaces of the transverse baffles; the face panel is fixedly welded above the longitudinal webs; and the side plates are fixedly arranged on the two sides of the single bent and twisted color band and are fixedly welded with the bottom plate, the transverse baffles, the reinforcing bars and the face plate. Since the transverse baffles are combined with the longitudinal webs, the out-of-plane distortion of external plates is effectively constrained and the cross stress of members is enabled to be evenly distributed; and at the same time, since the section width of the members is large and the twist is high, the application scope is wider and large-span high-twist molding structures can be realized.

Description

technical field [0001] The invention relates to a large steel column, in particular to a single bent and twisted colored ribbon and a manufacturing method thereof. Background technique [0002] With the rapid development of construction engineering, many super-long-span structures and many new architectural shapes have appeared. These structures and shapes are very complicated. In order to make the structure meet the requirements of architectural shapes, some components in the structure need to change with the curvature of the structure. And changes, these changes include bending, torsion and abnormal shape of components. The concrete structure can no longer achieve these shapes alone due to its own weight and later bearing capacity. At present, the combination of steel structure and concrete structure is used to realize it, because steel structures are easy to weld during welding. Large stress is generated, and the curved panel is prone to local deformation. Therefore, the...

[0002] With the rapid development of construction engineering, many super-long-span structures and many new architectural shapes have appeared. These structures and shapes are very complicated. In order to make the structure meet the requirements of architectural shapes, some components in the structure need to change with the curvature of the structure. And changes, these changes include bending, torsion and abnormal shape of components. The concrete structure can no longer achieve these shapes alone due to its own weight and later bearing capacity. At present, the combination of steel structure and concrete structure is used to realize it, because steel structures are easy to weld during welding. Large stress is generated, and the curved panel is prone to local deformation. Therefore, the box-shaped curved members currently produced are generally thin-walled steel plates, and the box section is relatively small, and the twist is small, which cannot meet the long-span and high-twist shape structure.
