Description

Technical Field

[0001] The utility model relates to the technical field of special-shaped steel, in particular to a special-shaped steel which is convenient to connect. Background Art

[0002] Special-shaped steel is the abbreviation of complex and special-shaped cross-section steel. It is a type of steel. Different from simple cross-section steel, the structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, galvanizing, etc., and is often used in building steel structures.

[0003] After searching, the existing Chinese patent with publication number CN202222311470.2 discloses a special-shaped steel structure splicing component. By providing a splicing component, the sliding block and the limit bar on one side of the special-shaped steel body are aligned with the sliding groove and the limit groove on the other side of the special-shaped steel body, and then the sliding block and the limit bar are inserted. The insertion of the limit bar causes the wedge to move up, and the upward traction spring of the wedge is compressed until the sliding block is completely inserted into the sliding groove. Under the action of the spring, the wedge bounces into the fixing groove, and the threaded rod is rotated to rotate the other set of wedges into the fixing groove. The two sets of wedges are arranged in opposite directions, thereby realizing the special-shaped steel body. The splicing between the bodies enhances the overall stability and anti-collision effect. By providing a splicing component, the sliding block and the limit strip on one side of the special-shaped steel body are aligned with the sliding groove and the limit strip on the other side of the special-shaped steel body, and then the sliding block and the limit strip are inserted. The insertion of the limit strip causes the wedge to move up, and the upward movement of the wedge pulls the spring to be compressed until the sliding block is completely inserted into the sliding groove. Under the action of the spring, the wedge bounces into the fixing groove, and the threaded rod is rotated to rotate the other set of wedges into the fixing groove. The two sets of wedges are arranged oppositely, thereby realizing the splicing between the special-shaped steel bodies and enhancing the overall stability and anti-collision effect.

[0004] The above technical scheme has the following defects: although such special-shaped steel structures can be connected by sliding grooves and limit grooves in cooperation with wedge-shaped pieces, in actual use, the steel structure connection requires not only horizontal and vertical splicing, but also folding connection, and a single set of bolt connections makes the overall strength general. In order to facilitate the rapid connection of special-shaped steel structures at corners, thereby facilitating the construction of steel structure projects, a special-shaped steel that is easy to connect is now proposed, which can quickly connect two groups of special-shaped steel materials, and is provided with an arc-shaped corner piece, so that the special-shaped steel can be quickly connected at the corner, and a positioning structure is provided, which can be used for rapid temporary connection of the special-shaped steel, and then reinforced connection, and the overall connection strength can be guaranteed without welding, and the special-shaped steel can be prefabricated and processed in the factory, and can be quickly connected on site, thereby speeding up the construction efficiency of the steel structure project.

[0005] In view of this, the author improves and solves the above problems, concentrates on research and cooperates with theoretical application, and finally proposes a technical solution with reasonable design and effective improvement of the above defects.

[0006] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to those skilled in the art.
