Description

Technical Field

[0001] The utility model relates to the technical field of steel structure accessories, in particular to a tie rod for steel structure. Background Art

[0002] In steel structure buildings, many beam structures need to be connected by tie rods. The existing tie rods are generally welded with a fixed plate at the end of a steel pipe, the fixed plate is perpendicular to the axis of the steel pipe, and then a connecting plate is welded on the fixed plate, the connecting plate is perpendicular to the fixed plate. There is a tie rod with this structure, and another type of tie rod is composed of a steel pipe and a connecting portion flattened at both ends of the steel pipe, and a mounting hole is set on the connecting portion.

[0003] However, no matter which type of tie rod is used, the connecting plate (part) at the end cannot be rotated or disassembled, which makes it inconvenient to use. Specifically, the above problems will cause the following phenomena when the tie rod is connected to the beam body: first, if the tie rod installation position (threaded hole) on the two beam bodies is not in the same plane as the connecting plate of the tie rod, the tie rod cannot be installed smoothly; second, when the tie rod is damaged (commonly seen on the connecting plate), the tie rod must be completely removed when it needs to be disassembled, and parts cannot be replaced individually, which makes disassembly and assembly extremely troublesome, laborious and time-consuming. Utility Model Content

[0004] The utility model aims to provide a tie rod for a steel structure, so as to solve the problem that the connecting plate at the end of the existing tie rod cannot be rotated and disassembled, resulting in great inconvenience in use.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A tie rod for a steel structure comprises a round tube, a sealing plate, a threaded rod, a zipper plate, a nut and a connector, wherein the sealing plates are symmetrically mounted at both ends of the round tube, the zipper plate is located on the inner side of the sealing plate, the threaded rod passes through the sealing plate and is connected to the zipper plate, the nut is connected to the threaded rod via a threaded structure, one of the threaded rods is connected to one of the connectors, and another of the threaded rods is rotatably connected to another of the connectors.

[0007] A further technical solution is that: the sealing plate is provided with a through hole matched with the zipper plate.

[0008] A further technical solution is that the zipper plate is a cross plate.

[0009] A further technical solution is that the round tube is composed of two sleeves which are slidably connected and fixed by bolts.

[0010] A further technical solution is: one of the sleeves is provided with a plurality of threaded holes matched with the bolts.

[0011] A further technical solution is that a positioning mark is provided between the threaded rod and the sealing plate.

[0012] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0013] The utility model provides a tie rod for steel structure. When the tie rod is in use, the zipper plate at one end is first inserted into a round tube, and then the zipper plate is pressed against a sealing plate on the round tube with a nut. At this time, a connecting head is fixed and connected to a beam body. Then the zipper plate at the other end is inserted into the round tube, and the same operation is performed. Then, the connecting head at this end is rotated to adapt to the beam body, and the installation of beam bodies at different positions can be adapted. In addition, it is convenient to disassemble and replace the two connecting heads, and there is no need to remove the tie rod as a whole, which is extremely convenient to use.
