Description

Technical Field

[0001] The present disclosure relates to the technical field of steel structure buildings, and in particular to a steel structure connection device and a steel structure building. Background Art

[0002] At present, in the field of construction, due to the need to fully utilize building space and the rapid increase in construction speed, traditional concrete structures have certain limitations in the construction field. Steel structure buildings have the advantages of light weight, high strength, high space utilization and fast construction speed. Therefore, in steel structure buildings, steel columns and steel beams are the main load-bearing structures, and the connection nodes between them are particularly important. In the early days, the full welding method was used to connect steel beams and steel columns, which easily led to cracks in the connection nodes under heavy loads. In the existing technology, a connecting mechanism is generally used to connect steel columns and steel beams. The connecting mechanism is set on the outer wall of the steel column and fastened by bolts. When the steel beam is under heavy load, it is easy for the steel beam to slip on the steel column, thereby affecting the safety of the steel structure building.

[0003] For example, Chinese patent number CN 114541595 A discloses a concrete column and steel beam connection structure, which includes a concrete column, a connection mechanism and a steel beam. The connection mechanism is sleeved on the outside of the concrete column, and the steel beam is fixedly connected to the connection mechanism. The connection mechanism includes two connection end plates symmetrically wrapped around the outside of the concrete column. There is a gap between the connection end plates and the concrete column, and a grouting layer is poured inside the gap. Two outer ring plates are symmetrically arranged on the upper and lower outer surfaces of the connection end plates, and connection ribs are evenly spaced between the two outer ring plates. The steel beam web and the connection ribs in the steel beam are fixedly connected by the connection plates, and the connection plates are fixedly connected to the steel beam web and the connection ribs respectively by connection bolts.

[0004] However, although the above-mentioned connection structure between the concrete column and the steel beam effectively improves the structural strength of the connection between the steel beam and the concrete column, when the steel beam is subjected to heavy load, the steel beam is prone to slip on the concrete column.

[0028] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure is further described in detail below with reference to specific embodiments:

[0029] like Figures 1 to 4 As shown, a steel structure connection device 10 of an embodiment includes a steel column 100 and a steel beam 200, wherein the steel column 100 includes a steel column body 1100 and a steel column connector 1200, wherein the steel column connector 1200 is provided on the steel column body 1100, and the steel beam 200 is fixedly connected to the steel column connector 1200, and the steel column connector 1200 includes an I-shaped support column 1210 and a pre-connected steel plate 1220, wherein the lower wing plate 1212 of the I-shaped support column 1210 is provided on the steel column body 1100, and the pre-connected steel plate 1220 is provided. 220 is vertically arranged on the web 1213 of the I-shaped support column 1210, and a connecting steel plate 300 corresponding to the pre-connected steel plate 1220 is arranged inside the steel beam 200. The pre-connected steel plate 1220 and the connecting steel plate 300 are detachably connected. The lower end face of the steel beam 200 is formed with a snap-fitting area 210 facing the steel column body 1100. The snap-fitting area 210 is used to snap-fit ​​and connect to the steel column body 1100, and the upper end face of the steel beam 200 is fixedly connected to the upper wing plate 1211 of the I-shaped support column 1210.

[0030] In this embodiment, since the lower wing plate 1212 of the I-shaped support column 1210 is provided on the steel column body 1100, the I-shaped support column 1210 is used to support and install the steel beam 200. Compared with the traditional connection mechanism directly sleeved on the outer peripheral wall of the steel column 100, the present disclosure avoids the situation where the steel beam 200 slips on the steel column 100 when the steel beam 200 bears a heavy load. In addition, since the pre-connected steel plate 1220 is vertically provided on the web 1213 of the I-shaped support column 1210, the connecting steel plate 300 provided inside the steel beam 200 is connected to the pre-connected steel plate 1220. The steel plate 1220 is detachably connected, ensuring the firmness of the connection between the steel beam 200 and the steel column 100. At the same time, a snap-fitting area 210 is formed on the lower end face of the steel beam 200 facing the steel column body 1100, and the steel column body 1100 is snap-fitted and connected to the snap-fitting area 210, and the upper end face of the steel beam 200 is fixedly connected to the upper wing plate 1211 of the I-shaped support column 1210, ensuring multiple connections between the steel beam 200 and the steel column 100, improving the firmness of the connection between the steel beam 200 and the steel column 100, and thereby improving the safety of the steel structure building 1.

In this embodiment, since one end of the support connection plate 400 is welded to the steel column body 1100 and the other end of the support connection plate 400 is welded to the upper end surface of the steel beam 200, on the one hand, it ensures that the upper end surface of the steel beam 200 is supported and prevented from deformation when the steel beam 200 is subjected to heavy loads, and on the other hand, it further improves the connection strength between the steel beam 200 and the steel column body 1100.

[0032] Furthermore, if Figure 4 As shown, in one embodiment, the number of the supporting connecting plates 400 is two, and the two supporting connecting plates 400 are respectively arranged on both sides of the connecting steel plate 300 to ensure that when the steel beam 200 is subjected to heavy loads, the supporting connecting plates 400 on both sides support it together, ensuring the uniformity of the force on the steel beam 200, thereby improving the bearing capacity of the steel beam 200.
