Description

Technical Field

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

[0002] Prefabricated construction refers to transferring a large amount of on-site work from traditional construction methods to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are prefabricated in factories, transported to the construction site, and assembled on-site using reliable connection methods. Currently, steel structure beam-column joints are typically fixed by welding. However, due to varying welding skills among construction workers, the strength of these joints is often low, making them prone to weld detachment and deformation, thus affecting the safety of the steel structure. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the existing technology, the purpose of this utility model is to provide a prefabricated steel structure component for building, so as to solve the safety problem.

[0004] The technical solution to the technical problem is as follows: It includes a vertical beam with four frames evenly distributed around its circumference. A first limiting plate and a second limiting plate are fixed on the vertical beam. The frames are located between the first and second limiting plates. Each frame has a mounting groove, which is a recessed groove. Frames aligned horizontally are fixedly connected by multiple first bolts, and frames aligned front-to-back are fixedly connected by multiple second bolts. A horizontal beam is placed within the mounting groove. The horizontal beam has multiple mounting holes. A third bolt passes through the mounting holes on each frame. First gaskets corresponding to the mounting grooves are located at the front and back of the horizontal beam. Each first gasket has a through groove, and multiple mounting holes are located inside the through grooves. Second gaskets corresponding to the mounting grooves are located at the top and bottom of the horizontal beam.

[0005] Preferably, there are two first bolts, which are distributed in the left-right direction and fix the left and right frames to the vertical beam. There are also two second bolts, which are distributed in the front-back direction. The first and second bolts are staggered and fix the front and back frames to the vertical beam.

[0006] Preferably, both the first gasket and the second gasket are L-shaped.

[0007] This utility model has the following advantages over traditional equipment: Assembled steel structure components, multiple frames are placed in sequence, and then the first and second bolts are used to fix the multiple frames to the vertical beam in sequence. Then the horizontal beam is inserted into the installation groove, and the third bolt is tightened to fix it. It is simple to operate, easy to load and unload, small in size, easy to carry, flexible, and efficient. Combined with the first and second limiting plates, the safety and stability of the overall steel structure are guaranteed. Attached Figure Description

[0010] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0011] Depend on Figures 1 to 2 A prefabricated steel structure component for buildings is provided, including a vertical beam 1, four frames 2 evenly distributed around the circumference of the vertical beam 1, a first limiting plate 3 and a second limiting plate 4 fixed on the vertical beam 1, the frames 2 being located between the first limiting plate 3 and the second limiting plate 4, the frames 2 having an installation groove 5, the installation groove 5 being a recess, the left and right aligned frames 2 being fixedly connected by multiple first bolts 6, the front and back aligned frames 2 being fixedly connected by multiple second bolts 7, a crossbeam 8 being placed in the installation groove 5, the crossbeam 8 having multiple installation holes 9, the frames 2 having a third bolt 10 penetrating the installation holes 9, the front and back of the crossbeam 8 having first gaskets 11 corresponding to the installation groove 5, the first gaskets 11 having through grooves 12, the multiple installation holes 9 being located inside the through grooves 12, the top and bottom of the crossbeam 8 having second gaskets 13 corresponding to the installation groove 5.

[0012] There are two first bolts 6, which are distributed in the left and right direction. The first bolts 6 fix the left and right frame 2 to the vertical beam 1. There are two second bolts 7, which are distributed in the front and back direction. The first bolts 6 and the second bolts 7 are staggered. The second bolts 7 fix the front and back frame 2 to the vertical beam 1.

[0013] To facilitate the placement of the first gasket 11 and the second gasket 13 between the crossbeam 8 and the frame 2, both the first gasket 11 and the second gasket 13 are L-shaped.

[0014] In use, during construction, the position of the vertical beam 1 steel structure is first fixed. Then, the four frames 2 are placed sequentially within the first limiting plate 3 and the second limiting plate 4. The left and right aligned frames 2 are secured to the vertical beam 1 by multiple first bolts 6, which are then tightened. The front and back aligned frames 2 are secured to the vertical beam 1 by multiple second bolts 7, which are then tightened. The first bolts 6 and second bolts 7 are staggered to avoid interference. At this point, the four frames 2 are respectively fixed to the vertical beam 1 steel structure. Finally, the horizontal beam 8 steel structure is inserted into the mounting groove 5 of the frame 2. Based on the gap between the crossbeam 8 and the mounting groove 5, different numbers of first shims 11 and second shims 13 are placed to ensure that the crossbeam 8 is tightly attached to the frame 2. The first shim 11 has a through groove 12, and multiple mounting holes 9 are located inside the through groove 12 to avoid the through groove 12 interfering with the mounting holes 9. Then, a third bolt 10 is installed on the frame 2. The third bolt 10 passes through the mounting holes 9 and the through groove 12. Tightening the third bolt 10 fixes the crossbeam 8 in the mounting groove 5 of the frame 2. The steel structure of the crossbeam 8 is installed on the four frames 2 in sequence. The first limiting plate 3 and the second limiting plate 4 play a limiting role to further ensure the stability between the crossbeam 8 and the vertical beam 1. The prefabricated structure is easy to install and safe and stable.

[0015] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
