Description

Technical Field

[0001] The utility model belongs to the technical field of steel structures, and specifically relates to a spliced steel structure steel beam. Background Technique

[0002] A steel beam is a truss structure assembled by welding and bolting steel sections together. It is made of welded H-shaped steel or hot-rolled H-shaped steel, or can be welded from steel plates into a closed box shape. Concrete is poured outside the H-shaped steel or inside the box-shaped steel plate to form a steel-concrete beam. During the use of a steel beam, splicing is usually required to form a spliced steel beam.

[0003] The utility model patent with the publication number 202123401844.1 discloses a corrosion-resistant spliced steel structure steel beam, including a spliced connection column. One end of the spliced connection column is fixedly connected with a steel beam connection head. An upper fixing hole is opened at one end of the steel beam connection head, a lower fixing hole is opened at the other end of the steel beam connection head, a steel beam slot is opened at one end of the steel beam connection head, a steel beam is arranged inside the steel beam connection head, an upper steel beam fixing hole is opened above one end of the steel beam, and a lower steel beam fixing hole is opened below one end of the steel beam. The beneficial effects are as follows: By inserting the steel beam into the steel beam slot, aligning the upper steel beam fixing hole with the upper fixing hole, and aligning the lower steel beam fixing hole with the lower fixing hole, and then screwing in fixing bolts inside, the splicing and installation fixation of the steel beams can be completed. Corrosion-resistant agents and other auxiliary coatings can be applied to the steel beam slot during installation. The fully inserted installation can effectively protect the splicing joint of the steel beam and prevent rapid oxidation and corrosion when exposed to the air.

[0004] However, the above device still has disadvantages during actual use. The more obvious one is that when it is necessary to disassemble and assemble the spliced steel beam, it is necessary to rotate multiple groups of bolts to remove the bolts from the fixing holes before the steel beam can be disassembled, which is not convenient for the disassembly and assembly of the spliced steel beam and reduces the installation efficiency of the spliced steel beam. For this reason, we propose a spliced steel structure steel beam. Content of the Utility Model

The positioning plate 230 and the second steel beam 200 are limited by the limiting block 231 in cooperation with a limiting component. A sliding plate 220 is fixedly connected to the side wall of the positioning plate 230 close to the second steel beam 200. The sliding plate 220 is used to connect the positioning plate 230 and the second steel beam 200. A through groove 210 for the sliding plate 220 to slide is opened on the second steel beam 200, and a limiting component for limiting the sliding plate 220 is arranged on the second steel beam 200.

[0025] Please refer to Figure 1 and Figure 3 , the installation mechanism includes a connection groove 110. The connection groove 110 is opened on the side wall of the first steel beam 100 and is matched with the second steel beam 200. The second steel beam 200 is supported by the connection groove 110.

[0026] Please refer to Figure 1 and Figure 3, a positioning groove 120 for supporting the limiting block 231 is formed on the side wall of the first steel beam 100, and the limiting block 231 is supported by the positioning groove 120.

[0027] Please refer to Figure 1 and Figure 3 , a limiting groove 130 is formed in the inner cavity of the positioning groove 120. The limiting block 231 is in an L shape, and the extending end of the limiting block 231 is located in the inner cavity of the limiting groove 130. When the limiting block 231 moves to the inner cavity of the extending end limiting groove 130, the limiting block 231 is limited in cooperation with the positioning groove 120.

[0028] Please refer to Figure 1 , Figure 2 and Figure 4 , threaded holes 221 for limiting the sliding plate 220 are formed on both sides of the top of the sliding plate 220. The screw rod 241 limits the sliding plate 220 in the through groove 210 through the threaded holes 221.
