Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, and in particular to a prefabricated building steel structure. Background Technology

[0002] Prefabricated steel structure buildings are a modern industrialized building form that uses steel structure as the main structure and adopts standardized design, factory production, assembly construction, information management and intelligent application. Its core lies in the fact that steel structure components (such as steel columns, steel beams, supports, etc.) are prefabricated in the factory and transported to the site, and then quickly assembled by bolting or welding to form a complete building structure system.

[0003] However, when existing steel structure components, such as steel beams, need to be connected, they are mostly fixed directly with bolts. This not only lacks good guidance during steel beam splicing and installation, making installation inconvenient, but also lacks good support at the joints, affecting the stability of the steel beam connections.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] The main purpose of this utility model is to provide a prefabricated steel structure for buildings, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A prefabricated steel structure for buildings includes a connecting frame. A No. 1 steel beam is inserted and fixedly installed at the right end of the connecting frame, a No. 3 steel beam is inserted and fixedly installed at the left end of the connecting frame, a No. 2 steel beam is inserted and fixedly installed at the lower end of the connecting frame, and a No. 4 steel beam is inserted and fixedly installed at the upper end of the connecting frame. Support devices are inserted and fixedly installed at both the upper and lower ends of the connecting frame.

[0008] Preferably, the connecting frame has slots at its upper, left, lower, and right ends, and two No. 1 bolts are installed at the upper, lower, left, and right front ends of the connecting frame. Two No. 1 bolt holes are also provided at the upper and lower front ends of the connecting frame. The No. 1 steel beam can be inserted into the slots on the connecting frame via its plug-in bracket. Then, the No. 1 bolt on the connecting frame can be screwed into the No. 2 bolt hole on the No. 1 steel beam. Similarly, the No. 2, No. 3, and No. 4 steel beams are installed in the same way. This plug-in installation allows the steel beams to be installed quickly and conveniently on the connecting frame.

[0009] Preferably, the support device includes a mounting cylinder with two No. 2 bolts installed at its front end. Support seats are fixedly installed at both the left and right ends of the mounting cylinder. The mounting cylinder is fixedly installed at the lower end of the connecting frame by inserting the No. 2 bolts. The mounting cylinder is sleeved onto the No. 2 steel beam, with the two support seats on the mounting cylinder abutting against the No. 1 and No. 3 steel beams respectively. Then, the No. 2 bolts are screwed into the No. 1 bolt holes on the connecting frame, thereby fixing the mounting cylinder and further supporting the connection of the connecting parts and the steel beams.

[0010] Preferably, the left and right ends of the first steel beam are fixedly installed with plug-in brackets, and the front ends of the two plug-in brackets are each provided with two bolt holes.

[0011] Preferably, the positions of the No. 2 bolt hole and the No. 1 bolt hole are corresponding front to back, and the positions of the No. 1 bolt hole and the No. 2 bolt hole are corresponding front to back.

[0012] Preferably, the two support seats abut against the lower end faces of the No. 1 steel beam and the No. 3 steel beam, respectively.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The No. 1 steel beam can be inserted into the slot on the connecting frame through the plug-in bracket on it. Then, the No. 1 bolt on the connecting frame can be screwed into the No. 2 bolt hole on the No. 1 steel beam. Similarly, the No. 2, No. 3, and No. 4 steel beams are installed in the same way. Through plug-in installation, not only can the steel beams be installed on the connecting frame quickly and conveniently, but also, by adding connecting frames, multiple steel beams can be spliced ​​and installed as needed.

[0015] 2. After the steel beam is installed on the connecting frame, the support device mounting sleeve is connected to the No. 2 steel beam, and the two support seats on the mounting sleeve abut against the No. 1 and No. 3 steel beams respectively. Then, the No. 2 bolt is screwed into the No. 1 bolt hole on the connecting frame to fix the mounting sleeve, thereby further supporting the connection of the connecting parts and the steel beam, and further improving the stability of the device.
