Description

Technical Field

[0001] This utility model relates to a prefabricated steel structure connection component, belonging to the field of steel structure manufacturing. Background Technology

[0002] Prefabricated steel structure beams exhibit significant advantages in construction engineering due to their lightweight and high strength characteristics. Their relatively light weight effectively reduces the load on the foundation, thereby decreasing the amount of foundation work required. In practical engineering applications, steel structure beams often work in conjunction with vertical support components such as columns and load-bearing walls to form a highly efficient and stable spatial force-bearing system.

[0003] The utility model with patent number 202421787583.2 discloses a steel structure beam-column structure, which relates to the field of steel structures. It includes two sets of fixed beams and columns. Two sets of stabilizing mechanisms are symmetrically arranged at the bottom of the surface of the fixed beams and columns. A telescopic column mechanism is slidably connected inside the fixed beams and columns. A crossbeam A is fixedly arranged on one side of one set of telescopic column mechanisms, and a crossbeam B is fixedly arranged on one side of the other set of telescopic column mechanisms. A docking mechanism is fixedly arranged at one end of the crossbeam B. A support mechanism is fixedly installed on one side of the telescopic column mechanism.

[0004] The aforementioned patent describes a method for quickly connecting and installing beams A and B by inserting a connecting rod and a connector into beam A, thereby connecting beams A and B. The positioning bolts are then tightened for fixation. However, this method is not comprehensive and has the following drawbacks: This connection method only involves bolting at the end faces, resulting in poor overall constraint on the two adjacent composite beams. Under large load moments, the connection ends are prone to breakage, and the overall load-bearing capacity of the connected joint is poor.

[0005] To solve one of the above problems, there is an urgent need for a prefabricated steel structure connection component. Utility Model Content

[0006] Based on the shortcomings of the prior art, the technical problem to be solved by this utility model is: how to achieve stable reinforcement of adjacent ends between adjacent first and second crossbeams by means of prefabricated steel structure connecting components, so as to effectively ensure the stability of the entire steel structure assembly. To this end, a prefabricated steel structure connecting component is provided.

[0007] The prefabricated steel structure connecting component of this utility model is used to connect a first crossbeam and a second crossbeam. It is characterized by comprising a middle connecting plate, a first connecting bolt, and a second connecting bolt.
