Description

Technical Field

[0001] The utility model relates to the technical field of steel structure cross beams, in particular to a steel structure cross beam which is convenient for disassembly and assembly. Background Technique

[0002] The steel structure cross beam is a key component in the building structure. It is mainly responsible for supporting horizontal loads such as roofs and floors and transmitting these loads to the vertical support structure. The steel structure cross beam is usually made of steel because steel has high strength, good ductility and seismic resistance. The design and manufacture of the steel structure cross beam are developing in the direction of higher efficiency, higher precision and better adaptability. By adopting advanced design concepts and technologies, modern steel structure cross beams can better meet the needs of various construction projects while ensuring the safety and reliability of the structure.

[0003] In the prior art, when installing the steel structure cross beam, it is generally directly welded or fixedly connected with angle codes using bolts, and then the angle codes are installed on the columns. When welding, the installation and disassembly are more troublesome. When directly using bolts for fixation, only using bolts for fixation lacks other limit fixation structures and is not firm enough. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is that when installing the steel structure cross beam in the prior art, the welding disassembly is very inconvenient, and when using bolts for installation, there is a lack of other limit fixation structures and it is not firm enough.

[0005] To solve the above technical problem, a technical solution adopted by the utility model is: to provide a steel structure cross beam which is convenient for disassembly and assembly, including a cross beam body. Angle codes required for fixing the cross beam body are arranged at both ends of the cross beam body. Both of the two angle codes include vertical plates and horizontal plates, and the horizontal plates are fixedly connected to one side of the surface of the vertical plates.

[0006] A first pressing block for limiting the cross beam body is fixedly connected to the top of the horizontal plate. An installation groove is formed on one side of the surface of the horizontal plate. A second pressing block is slidably installed inside the installation groove. A fastening component is arranged on one side of the surface of the second pressing block, and a pop-up component is arranged inside the installation groove.

[0007] Preferably, the fastening component includes an extended bolt located on one side of the surface of the second pressing block. A threaded hole is formed on the inner side wall of the installation groove. One end of the extended bolt movably penetrates through the second pressing block and is threadedly installed inside the threaded hole. Threadedly installing the extended bolt inside the threaded hole can fixedly install the second pressing block inside the installation groove.

[0008] Preferably, the pop-up component includes two cavities formed on the inner side wall of the installation groove. The inner side walls of the two cavities are both slidably connected with ejector rods. One end of each of the two ejector rods extends through and is fixedly connected to a cushion pad inside the installation groove. One end of each of the two ejector rods located inside the cavity is fixedly connected with a spring. One end of each of the two springs is fixedly connected to the inner bottom of the two cavities respectively. The elastic force of the spring can push the ejector rod and eject the second pressing block towards the outside of the installation groove.

[0009] Preferably, two sliders are fixedly connected to the inner bottom of the installation groove. Two sliding grooves are formed at the bottom of the second pressing block. The two sliders are respectively installed and slidably connected inside the two sliding grooves. The cooperation of the slider and the sliding groove can make it more convenient for the second pressing block to be slidably installed into the installation groove.

[0010] Preferably, the crossbeam body is fixedly installed on the top of the cross plate by bolts. Bolt installation is more convenient for installation and disassembly than welding.

[0011] Preferably, a plurality of installation holes for fixing are formed through one side of the surface of the vertical plate for fixing and installing on the vertical beam.

[0012] Preferably, shock-proof isolation washers are installed between both ends of the crossbeam body and the two vertical plates, which can improve stability and reliability and reduce noise.

[0013] The beneficial effects of the present utility model are as follows:

[0014] By setting components such as the second pressing block, extension bolt, spring and ejector rod, after installing the crossbeam body on the top of the corner bracket, rotating the extension bolt to make it rotate and tighten inside the threaded hole can make the second pressing block be slidably installed into the installation groove. The second pressing block can cooperate with the first pressing block to limit and fix the crossbeam body. When disassembling, rotating the extension bolt, the resilience of the spring will push the ejector rod towards the outside of the installation groove, so that the second pressing block slides out of the installation groove. Compared with the welding installation in the prior art, the disassembly and assembly are more convenient. Compared with simply using bolts for fixing, a limit fixing device is added, making it more firm. BRIEF DESCRIPTION OF THE DRAWINGS
