Specifically, in combination with Figure 1 , Figure 2The support component one 2 comprises a plurality of support bodies one 21 above the prefabricated slab body 1 and a plurality of support bodies two 22 inserted into the prefabricated slab body 1. The support bodies one 21 and the support bodies two 22 are arranged alternately along the extension direction of the support component one 2. The support bodies one 21 are welded and fixed with the support component one 2, and the support bodies two 22 are welded and fixed with the support component three 4.
[0025] As shown in Figure 1 , Figure 2 , a plurality of support components four 5 are installed on the prefabricated slab body 1. The support components four 5 are steel bars. A plurality of support components four 5 are arranged along the length direction of the prefabricated slab body 1. The length direction of the support components four 5 is arranged along the width direction of the prefabricated slab body 1. The support components four 5 are welded with the support component three 4 and the support body two 22 respectively. Figure 4 As shown in , when the prefabricated slab body 1 is installed on the stairs, the prefabricated slab bodies 1 are placed at intervals. The adjacent prefabricated slab bodies 1 are spliced by pouring concrete. The steel bars protruding from the prefabricated slab body 1 play a supporting role.
[0026] In combination with Figure 1 , Figure 3 , the prefabricated slab body 1 is provided with a groove 11. The grooves 11 are arranged in pairs. The grooves 11 are located on both sides of the width direction of the prefabricated slab body 1. The length direction of the grooves 11 is arranged along the width direction of the prefabricated slab body 1. The grooves 11 penetrate through both ends of the width direction of the prefabricated slab body 1. The grooves 11 are poured with a pouring body 6 which is concrete.
[0027] In combination with Figure 1 , Figure 3 , the prefabricated slab body 1 is provided with a hole 12. The upper end of the hole 12 penetrates through the top of the prefabricated slab body 1. The lower end of the hole 12 communicates with the groove 11. The upper end of the hole 12 has a smaller diameter and the lower end has a larger diameter. Specifically, the hole 12 is a tapered hole.
[0028] The pouring body 6 is provided with a support component five 7. The support component five 7 penetrates through the groove 11. The length direction of the support component five 7 protrudes from both ends of the width direction of the prefabricated slab body 1. The support component five 7 is connected with a connecting component 8. The connecting component 8 is arranged along the axial direction of the hole 12. The upper end of the connecting component 8 protrudes from the top of the hole 12. The lower end of the connecting component 8 extends into the groove 11. The support component five 7 penetrates through the bottom of the connecting component 8. The lower end of the support component five 7 abuts against the inner wall of the connecting component 8.
[0029] The groove 11 is reserved at the bottom of the prefabricated slab body 1. The connecting component 8 is placed in the hole 12. The support component five 7 is inserted into the groove 11. The support component five 7 penetrates through the bottom of the connecting component 8. The connecting component 8 pulls up the support component five 7.

The whole prefabricated floor can be lifted and hoisted by pulling the connecting head 81. Since the supporting component five 7 passes through the connecting component 8, the supporting component five 7 is integrated with the pouring body 6, and the whole prefabricated floor is lifted by pulling the pouring body 6 during lifting, and the pouring body 6 is located at the bottom of the prefabricated slab body 1. This structure is safer during hoisting, and there is no safety problem caused by low welding strength of the steel bar welding point during hoisting.
[0031] By arranging the channel 12, when the prefabricated slab body 1 is hoisted to the building body and the upper end of the prefabricated slab body 1 is poured subsequently, the concrete flows into the channel 12, and since the upper end of the channel 12 has a small diameter and the lower end has a large diameter, the bonding force between the prefabricated slab body 1 and the subsequent pouring floor above it is increased after the concrete solidifies. The improvement of this bonding force is more obvious when the prefabricated slab body 1 is poured in the inverted direction, that is, when the prefabricated slab body 1 is poured in the state that the upper end of the prefabricated slab body 1 faces downward. Figure 3 The prefabricated slab body 1 is inverted in the direction shown, that is, the prefabricated slab body 1 is poured in the state that the upper end of the prefabricated slab body 1 faces downward, and the structure has better performance in stability.
