X-shaped bent colored ribbon and making method thereof

Abstract

The invention discloses an X-shaped bent colored ribbon. The X-shaped bent colored ribbon is formed by crossing single bent steel columns; the X-shaped bent colored ribbon consists of three parts, namely a middle part, a left wing and a right wing; the middle part, the left wing and the right wing are made of the bent steel columns; and the middle part, the left wing and the right wing are spliced or welded to form the X-shaped bent colored ribbon. The X-shaped bent colored ribbon is skilful in structural design, and has strong bearing capacity; meanwhile, multiple bent steel columns can be organically combined into a whole to realize the three-dimensional effect of the bent colored ribbon; in a making method of the bent colored ribbon, the conventional assembly sequence of installing side plates and then installing a face plate is broken; and the sequence of installing the face plate and then installing the side plates is adopted in the method, so that more welding and assembly space is provided, the cross section of the X-shaped bent colored ribbon is not limited by assembly and welding, parts in a box can be assembled and welded from two sides by a worker, and efficiency and quality of assembly and welding are improved.

Description

technical field [0001] The invention relates to a large steel column, in particular to an X-shaped curved and twisted 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 box...

[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.
