The basic idea of ​​prefabricated frame structures is to divide the frame structure into columns, beams and floor slabs, prefabricate the columns, beams and floor slabs in the prefabricated component factory, and then transport them to the construction site for installation and connection to form a prefabricated frame structure.

[0004] In order to ensure the connection strength between the plate and the beam, the existing technology generally uses a large number of bolts and bolt expansion agents, which is not conducive to achieving efficient assembly and disassembly of prefabricated buildings. Among them, the bolts in each hole must be reinforced with expansion agents, and the number of bolts themselves is large, which makes the construction complicated; disassembly is also inconvenient. After the expansion agent is applied, it will become impossible to disassemble and can only be forced to be pushed down; a large amount of bolt expansion agents, the number of bolt holes and the amount of concrete used will result in high costs and increased construction difficulty.

[0005] In order to solve the above problems, it is necessary to propose a new type of connecting device between the plate and the beam. Summary of the invention

[0020] The technical solution of the present invention is further described below through the accompanying drawings and embodiments.

[0021] Example like Figure 1-3As shown, a connection device for prefabricated steel beams and prefabricated panels for assembled buildings includes a prefabricated channel steel beam 1, a beam-slab connection clamp 2 and a prefabricated panel 3, and the prefabricated panel 3 is made of concrete. An upper mounting groove 4 and a lower mounting groove 5 are arranged corresponding to the top plate and the bottom plate of the prefabricated channel steel beam 1 on one side of the beam-slab connection clamp 2, and the upper mounting groove 4 and the lower mounting groove 5 are respectively connected to the top plate and the bottom plate through a convenient connection piece. The convenient connection piece includes two first bolts located at the ends of the prefabricated channel steel beam 1 and at least one bite stripe. In this embodiment, two bite stripes are provided and located between the two first bolts.

[0022] The bite stripes include a first stripe block 7 and a second stripe block 8 that are arranged opposite to each other. The first stripe block 7 is located on the top plate and the bottom plate of the prefabricated channel steel beam 1. The first stripe block 7 includes a plurality of grooves 71 that are evenly distributed along the length direction of the prefabricated channel steel beam 1, and the groove bottom of the groove 71 is provided with evenly distributed bite teeth 72. The second stripe block 8 is located in the upper mounting groove 4 and the lower mounting groove 5, and the second stripe block 8 includes a plurality of convex strips 81 that are evenly distributed along the length direction of the beam-slab connecting clamp 2. The convex strip 81 is provided with a bite groove 82 that is compatible with the bite tooth 72 structure. The matching connection between the bite tooth 72 and the bite groove 82 can generate a mechanical bite force to ensure that the prefabricated channel steel beam 1 and the beam-slab connecting clamp 2 have sufficient bending resistance and shear resistance.

[0023] The upper mounting groove 4 and the lower mounting groove 5 are both provided with a first sealing rubber pad 11 arranged alternately with the first stripe block 7, and the first sealing rubber pad 11 is provided with a first slot 12 adapted to the top plate or bottom plate structure. The upper mounting groove 4, the lower mounting groove 5, the prefabricated channel steel beam 1 and the first sealing rubber pad 11 located at the end are all provided with a first connecting hole 6 arranged corresponding to the first bolt. In this embodiment, the first connecting hole 6 on the prefabricated channel steel beam 1 is a hole groove with an internal thread, and the first connecting hole 6 on the upper mounting groove 4, the lower mounting groove 5 and the first sealing rubber pad 11 is a through hole, so that the first bolt can be screwed into the hole groove to achieve the tightening and fixing of the first bolt. After the first bolt is installed in the first connecting hole 6 and tightened, the first sealing rubber pad 11 can be pressed between the upper mounting groove 4 and the top plate, or between the lower mounting groove 5 and the bottom plate, filling the gap between the prefabricated channel steel beam 1 and the beam-plate connecting clamp 2.

[0024] The other side of the beam-slab connection clamp 2 is provided with a connection groove 9 corresponding to the prefabricated plate 3, and the connection groove 9 is connected to the prefabricated plate 3 through a plurality of second bolts and nuts. In this embodiment, five second bolts are provided and are evenly distributed along the length direction of the prefabricated plate 3. A second sealing pad 13 is provided in the connection groove 9, and a second slot 14 adapted to the structure of the prefabricated plate 3 is provided on the second sealing pad 13. The connection groove 9, the second sealing pad 13 and the prefabricated plate 3 are all provided with a second connection hole 10 corresponding to the second bolt. In this embodiment, all the second connection holes 10 are through holes, and nuts are needed to fix them after the second bolts are installed. After the second bolt is installed in the second connection hole 10 and the nut is tightened, the second sealing pad 13 can be pressed between the connection groove 9 and the prefabricated plate 3 to fill the gap between the prefabricated plate 3 and the beam-slab connection clamp 2.

[0025] When in use, the prefabricated channel steel beam 1, the beam-slab connecting clamp 2 and the prefabricated plate 3 in the device can be processed in advance by the factory. When assembling, first install the first sealing rubber pad 11 into the upper installation groove 4 and the lower installation groove 5 of the beam-slab connecting clamp 2, and then insert the top plate and the bottom plate of the prefabricated channel steel beam 1 into the corresponding first slot 12 of the first sealing rubber pad 11, and then screw the first bolt into the first connecting hole 6 and tighten it. After tightening, the first sealing rubber pad 11 is compacted, and the bite teeth 72 on the first stripe block 7 and the bite grooves 82 on the second stripe block 8 are tightened. Mechanical bite is achieved to ensure the sealing between the prefabricated channel steel beam 1 and the beam-slab connecting clamp 2 while achieving a stable connection between the two. Then, the second sealing pad 13 is installed in the connecting groove 9 of the beam-slab connecting clamp 2, and then the prefabricated panel 3 is inserted into the second slot 14 of the second sealing pad 13 and the second bolt is installed. After tightening the second bolt with a nut, a sealed connection and a stable connection between the prefabricated panel 3 and the beam-slab connecting clamp 2 can be achieved; when disassembling, only the first bolt and the second bolt need to be pulled out. After pulling out, the mechanical bite force will automatically loosen and the panel can be directly disassembled.

[0026] Therefore, the present invention adopts a connection device of prefabricated steel beams and prefabricated panels for prefabricated buildings with the above-mentioned structure, avoiding the use of a large number of bolts and expansion agents, thereby reducing construction costs and construction difficulty, and utilizing beam-slab connection clamps to ensure the connection strength between the prefabricated steel beams and the prefabricated panels, while enabling rapid assembly and disassembly.
