Description

Technical Field

[0001] This utility model specifically relates to a structure for an anti-disengagement connector for steel structures in buildings, belonging to the field of building engineering. Background Technology

[0002] Bolted connections in steel structure engineering are one of the most common connection methods. They are widely used due to their quick construction and ability to withstand large tensile and shear forces. However, in actual construction applications, they also have some drawbacks and limitations. When connecting two steel structures, the bolt head is inserted into the bolt holes of both steel structures on one side, and the nut is tightened on the other side. This often results in the nut turning back and the bolt coming off the thread. It is necessary to use a tool to limit the bolt head on one side of the steel structure and then tighten the nut on the other side. The installation operation is relatively complicated, inefficient, time-consuming, and labor-intensive.

[0003] Therefore, in order to address the shortcomings of existing technologies, a structure for an anti-disengagement connector for building steel structures is proposed. Utility Model Content

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a steel structure anti-disengagement connector structure, comprising a column, a beam, and bolts, wherein the bolts connect the beam and the column. The column and the beam are both rectangular structures. The column is composed of a wall panel with multiple square and round holes. The bolt includes a nut, a locking bolt, and a bolt head. A square base shaft is provided between the bolt head and the threaded post. A cotter pin is provided on the end face of the threaded post. The locking bolt is inserted into and fixed in the cotter pin to lock the bolt.

[0006] Furthermore, the crossbeam is provided with symmetrically opened operating holes.

[0007] Furthermore, the bolt is pre-inserted into the square hole through the round hole, the square base shaft is engaged with the square hole, and the bolt head on one side of the bolt is in a fixed and restricted state.

[0008] Furthermore, the crossbeam is connected via a sleeve hole through the exposed threaded post.

[0009] Furthermore, the bolt nut is fixed to the threaded post through the operating hole.

[0010] The beneficial effects of this utility model are:

[0011] The utility model discloses a locking bolt is inserted into the split pin in the threaded column, thereby making the radial clearance state between threaded column and bolt head change into locking state, and the locking state can prevent bolt female from being unexpectedly tripped under the vibration or other adverse conditions of threaded column, and secondly, when the square base shaft of steel structure one side bolt and square hole limit are clamped, the bolt female can be tightened on the other side, and the installation operation is simple, and the efficiency is high, and the comprehensive cost cost is saved.
