[0027] Please refer to Figures 1-5 , the present utility model provides a technical solution:

[0028] A prefabricated steel component convenient for splicing, including a connecting piece 1. Both side walls of the connecting piece 1 are provided with connecting grooves 2. An I-beam 3 is clamped inside the connecting groove 2. Connecting components 4 are fixedly arranged on both sides of the side wall of the connecting piece 1. The connecting component 4 includes a groove 401. A limiting plate 402 is slidably connected inside the groove 401. A moving rod 403 is fixedly arranged on the side wall of the limiting plate 402. A spring 404 is sleeved on the outer circumference of the moving rod 403. One end of the spring 404 is fixedly connected to the side wall of the limiting plate 402, and the other end of the spring 404 is fixedly connected to the inner wall of the groove 401. The moving rod 403 passes through the side wall of the connecting piece 1 and is fixedly provided with a pull ring 405. An insertion block 406 is fixedly arranged on the other side of the limiting plate 402. Slots 407 are opened at both ends of the side wall of the I-beam 3. A reinforcing component 5 is fixedly arranged on the top of the side wall of the connecting piece 1. In the present utility model, a worker pulls the pull ring 405 to move the moving rod 403 outwards, so that the limiting plate 402 drives the insertion block 406 to move, inserts the I-beam 3 into the groove 401, releases the pull ring 405, and the resilience of the spring 404 drives the insertion block 406 to enter the slot 407, thereby fixing the I-beam 3. Insert another I-beam 3 into the groove 401 on the other side and repeat the operation, which is convenient for connecting two I-beams 3 and improves the convenience of splicing the prefabricated steel component.

[0029] Specifically, the reinforcing component 5 includes a plurality of first screw holes 501 opened at the top of the side wall of the connecting piece 1. A plurality of second screw holes 502 are opened at both ends of the top of the I-beam 3. A splicing block 503 is threadedly connected to the top of the side wall of the connecting piece 1. A plurality of first through holes 504 are opened on the side wall of the splicing block 503, and a plurality of second through holes 505 are opened at the top of the splicing block 503. Bolts are passed through the first through holes 504 and screwed into the first screw holes 501, so that the splicing block 503 is fixedly connected to the connecting piece 1. Bolts are passed through the second through holes 505 and screwed into the second screw holes 502, so that the splicing block 503 is fixedly connected to the I-beam 3, which is convenient for sharing the pressure of the prefabricated steel component convenient for splicing and preventing the connection from breaking.

[0030] Furthermore, the size of the connecting groove 2 matches the size of the I-beam 3, and the two connecting grooves 2 are arranged in parallel. By arranging the connecting grooves 2 in parallel, it is convenient to make the connection of the two I-beams 3 neat and prevent it from affecting the construction and use of the prefabricated steel component.

[0031] It should be noted that the cross-section of the insertion block 406 is cross-shaped, and the size and position of the insertion block 406 match the size and position of the slot 407. With the cross-shaped insertion block 406, it is prevented that the insertion block 406 loosens in the slot 407, and the stability of the prefabricated steel component convenient for splicing is increased.

[0032] It should be noted that the size and position of the first screw hole 501 match the size and position of the first through hole 504, and the size and position of the second screw hole 502 match the size and position of the second through hole 505. The first screw hole 501 that matches the size and position of the first through hole 504 facilitates the installation of bolts, thereby making the connection between the connecting member 1 and the I-beam 3 more stable.

[0033] In addition, the cross-section of the splicing block 503 is L-shaped, and the height of the splicing block 503 is equal to the height of the top of the side wall of the connecting member 1. The L-shaped splicing block 503 reduces the volume of the splicing block 503 and reduces the cost of the prefabricated steel member.

[0034] Working principle: When the prefabricated steel members need to be spliced by this device, the staff pulls the pull ring 405 to move the moving rod 403 outwards, so that the limiting plate 402 drives the insertion block 406 to move, inserts the I-beam 3 into the groove 401, releases the pull ring 405, and the resilience of the spring 404 drives the insertion block 406 into the slot 407, thereby fixing the I-beam 3. Insert another I-beam 3 into the groove 401 on the other side and repeat the operation to facilitate the connection of the two I-beams 3 and improve the convenience of splicing the prefabricated steel members. The bolts pass through the first through hole 504 and are screwed into the first screw hole 501, so that the splicing block 503 is connected and fixed to the connecting member 1. The bolts pass through the second through hole 505 and are screwed into the second screw hole 502, so that the splicing block 503 is connected and fixed to the I-beam 3, which is convenient for sharing the pressure of the prefabricated steel members to be spliced and improving the stability. By setting the insertion block 406 to a cross shape, the insertion block 406 is prevented from loosening in the slot 407, and the stability of the prefabricated steel members to be spliced is increased.
