Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and specifically to a connecting member and an assembled steel beam structure. Background Technique

[0002] The I-beam is also called a steel beam, which is a long steel bar with an I-shaped cross-section. The I-beam is divided into ordinary I-beams and light I-beams, which are steel sections with an I-shaped cross-section.

[0003] In the prior art, in order to improve the on-site construction efficiency, the traditional construction process of welding steel beams is abandoned. Currently, assembled connecting fasteners are used to fix the steel beam on the column, which greatly improves the on-site construction efficiency. Moreover, the connecting fasteners mostly use bolt structures for fastening, so the technical requirements for workers in construction are low, which is convenient for the promotion of the process.

[0004] However, the steel beam needs to be lifted by a hoisting device before the two ends of the steel beam can be fixed by a bolt structure. That is, before the bolt structure is fastened, the steel beam needs to be continuously suspended, which occupies the hoisting device. If a pre-fixing structure can be installed on the connecting fastener of the steel beam, the hoisting of the hoisting device can be cancelled, so that the hoisting device can be freed up for the next step of work, thereby improving the on-site construction efficiency.

At this time, the equipment for hoisting the steel beam 2 can be withdrawn, and then the screw rods on the surfaces of the clamping plate 1 and the fixing plate 26 are tightened to realize the reinforcement of the hanging installation of the clamping plate 1.

[0029] Embodiment Two

[0030] Refer to the appendix Figure 4 and Figure 5 , on the basis of Embodiment One, in order to realize the rapid assembly of the clamping plate 1 and the steel beam 2, the clamping plate 1 is in a "C"-shaped plate structure, the steel beam 2 is between the top plate and the bottom plate of the clamping plate 1, clamping screw rods are screwed on both the top plate and the bottom plate of the clamping plate 1, and the clamping screw rods pass through the plate body of the clamping plate 1 to clamp the steel beam 2.
