On the flat plate; push the abutment ribs 721 toward each other, the abutment ribs 721 compress the elastic member 71, and at the same time the fixed ribs 722 slide in the sliding sleeve 723, so that the reinforcement mesh 3 is reduced in size in the direction perpendicular to the main beam 11, and the reinforcement mesh 3 Put it between two adjacent main beams 11, insert the positioning rib 8 into the positioning hole 21, then release the hand, the deformation of the elastic member 71 is restored, and the abutting ribs 721 are in contact with the vertical plate of the main beam 11, Weld the positioning rib 8 with the floor deck 2, bend the bottom end of the positioning rib 8 through the floor deck 2 to the direction close to the main beam 11, and cross the ends of the two positioning ribs 8 of the main beam 11. The elastic connectors are fixedly connected between the parts. When in use, the fixing rib 722 can only move along the direction of the sliding sleeve 723. The setting of the fixing rib 722 makes it difficult for the connecting part between the transverse rib 31 and the abutting rib 721 to be deformed in the vertical direction, so that the floor slab is not easy to break and strengthens. The vibration resistance of the floor slab is improved; the vibration transmitted to the transverse bar 31 can be removed by the elastic member 71, which reduces the impact of the floor slab on vibration and improves the seismic resistance of the floor slab; the vibration force transmitted to the positioning rib 8 can be transmitted by the elastic connecting piece. When removed, the elastic connecting piece can produce large deformation without breaking, so that the connected positioning ribs 8 are not easily broken, so that the connection between the floor slab and the steel beam 1 is not easily broken, and the seismic resistance of the floor slab is improved.

On the upper surface of the main beam 11, the first distribution rib net 6 is bound, so that the first distribution rib net 6 is welded with the main beam 11 and the connecting beam 12, and then the connecting rib 4 and the first distribution rib net 6 are welded and connected. The second distribution rib 5 is bound above the first distribution rib 6 , so that the second distribution rib 5 is fixedly connected with the connecting rib 4 . The first distribution rib net 6 and the second distribution rib net 5 play a strengthening and supporting role on the concrete filling layer 13 on the upper part of the steel beam 1, so that the concrete filling layer 13 is not easily deformed and fractured when it is subjected to vibration, and the seismic resistance of the floor slab is improved; The rib 4 and the second distribution rib net 5 are connected with the first distribution rib net 6 and the connecting component, which strengthens the integrity between the floor slab and the steel beam 1 .

The pouring formwork is supported under the main beam 11 and the connecting beam 12 , and concrete is poured to form a concrete filling layer 13 .
