Referring to fig. 1 and 2, an embodiment of the present invention provides a precast element, which includes a precast concrete layer 42 and a precast element connecting device 41.

The prefabricated part connecting device 41 includes a mounting box 20 and a connection member 10. The mounting box 20 includes a first side 23 and a second side 24 facing away from each other, and the second side 24 defines an opening 21 communicating with the inner cavity of the mounting box 20. Connecting piece 10 includes interconnect's pre-buried section 11 and linkage segment 12, and pre-buried section 11 is located the first side 23 of mounting box 20, and linkage segment 12 runs through the first side 23 of mounting box 20 to can accomodate in the inner chamber of mounting box 20 or wear out to the second side 24 of mounting box 20 by uncovered 21 through buckling. Alternatively, the connector 10 may be a steel bar.

The mounting box 20 is pre-buried in the precast concrete layer 42, and the second side 24 of the mounting box 20 is exposed to a side surface of the precast concrete layer 42.

In the prefabricated part connecting device, during the production process of the prefabricated part, the connecting section 12 of the connecting piece 10 is firstly accommodated in the inner cavity of the mounting box 20 in a bending mode. The mounting box 20 is then placed on the trolley with the second side 24 of the mounting box 20 abutting the trolley. And then, a precast concrete layer 42 is formed by pouring, so that the mounting box 20 and the embedded section 11 of the connecting piece 10 are embedded in the precast concrete layer 42. Due to the fact that the second side 24 of the mounting box 20 is attached to the surface of the trolley, concrete materials are prevented from entering between the mounting box 20 and the trolley when pouring is conducted, and the second side 24 of the mounting box 20 is exposed to the surface, facing the trolley, of the precast concrete layer 42.

When assembling the prefabricated component 40, the connecting section 12 of the connecting member 10 accommodated in the mounting box 20 is only required to be bent straight, so that the connecting section 12 penetrates out from the opening 21 to the second side 24 of the mounting box 20, at this time, the reinforcement cage in the cast-in-place concrete 43 can be connected with the connecting section 12 of the connecting member 10, and after the cast-in-place concrete 43 is poured, the connection between the prefabricated component 40 and the cast-in-place concrete 43 can be completed. It should be noted that the prefabricated components may be prefabricated wall panels, and the cast-in-place concrete 43 may be cast-in-place floor slabs.

The prefabricated part connecting device 41 and the prefabricated part 40 are used for accommodating the connecting section 12 positioned on the side, away from the trolley, of the prefabricated part 40 in the mounting box 20 in a bending mode, so that the mutual interference between the connecting section 12 and the trolley during pouring is avoided. Compared with the prior art, the connecting section 12 is prevented from being buried in the precast concrete layer 42 of the precast member 40 and dug out during assembly, so that the complexity and cost of the process are greatly reduced, and the installation efficiency is improved.

In the embodiment, the prefabricated part connecting device 41 further comprises a cover plate 30, and the cover plate 30 is detachably covered on the opening 21. In this way, covering the opening 21 by the cover plate 30 can prevent concrete from entering the installation box 20 from the opening 21 when the precast concrete layer 42 of the precast element 40 is poured, resulting in difficulty in cleaning.

In particular, in the embodiment, the connection member 10 includes a plurality of pieces, so that the cast-in-place concrete 43 and the prefabricated part 40 are connected by the plurality of connection members 10, and the connection strength between the cast-in-place concrete 43 and the prefabricated part 40 is ensured.

Further, the plurality of coupling members 10 are arranged in two rows at intervals along a first direction (i.e., an up-down direction in fig. 2) perpendicular to the longitudinal direction of the mounting box 20, and each row includes the plurality of coupling members 10 arranged at intervals along the longitudinal direction of the mounting box 20. The connecting sections 12 of the plurality of connecting pieces 10 are connected with the steel bars of the prefabricated part 40, so that the connecting strength between the prefabricated part 40 and the cast-in-place concrete 42 is further enhanced.

Further, the embedded sections 11 of the two rows of connecting pieces 10 are bent towards the direction away from each other, so that the anchoring strength of the embedded sections 11 of the connecting pieces 10 is enhanced, and the connecting strength between the prefabricated part 40 and the cast-in-place concrete 43 is further improved. Optionally, the extending direction of the embedded sections 11 is a gravity direction (i.e., an up-down direction in fig. 2), the embedded sections 11 of the upper row of the connecting members 10 extend longitudinally upward, and the embedded sections 11 of the lower row of the connecting members 10 extend longitudinally downward.

In an embodiment, the connecting section 12 of each connector 10 can be bent toward the longitudinal direction of the mounting box 20 to be received in the inner cavity of the mounting box 20. As described above, by bending the connection section 12 of the connector 10 in the longitudinal direction of the mounting box 20, the size of the mounting box 20 in the width direction perpendicular to the longitudinal direction can be reduced, and the volume of the mounting box 20 can be reduced.

In particular, in the embodiment, the outer surface of the mounting case 20 has a rough surface. Alternatively, the rough surface may be a concave-convex surface with regular or irregular texture to increase the bonding force between the mounting box 20 and the precast concrete layer 42 and prevent the mounting box 20 from falling off the precast concrete layer 42 of the precast member 40.

In the embodiment, the connecting member 10 is welded to the mounting box 20. So, with connecting piece 10 and mounting box 20 welded fastening, avoid pouring the relative movement of taking place for connecting piece 10 in the in-process mounting box 20 of formation precast concrete layer 42 for concrete material gets into between mounting box 20 and the platform truck.

Specifically, in the embodiment, the surface of the second side 24 of the mounting box 20 is flush with the surface of the precast concrete layer 42, so that the second side 24 of the mounting box 20 can directly abut against the trolley, concrete cannot enter between the mounting box 20 and the trolley during pouring, and after the precast concrete of the precast element 40 is poured and molded, the mounting box 20 is directly exposed on the surface of the precast concrete layer 42, thereby facilitating subsequent construction.

Further, a reinforcement cage is pre-embedded in the precast concrete layer 42, and the reinforcement cage is fixedly connected with the pre-embedded section 11. Therefore, the embedded section 11 of the connecting piece 10 is connected with the reinforcement cage in the precast concrete layer 42, the anchoring strength of the embedded section of the connecting piece 10 is further improved, and the connection strength of the cast-in-place concrete 43 and the precast element 40 is enhanced. It should be noted that, the structure and the installation manner of the reinforcement cage can adopt the mature prior art, and therefore, the detailed description thereof is omitted.

And then, connecting the embedded section 11 of the connecting piece 10 with the reinforcement cage of the prefabricated part 40, placing the reinforcement cage into the trolley after connection is completed, pouring concrete to form a prefabricated concrete layer 42, and exposing the second side 24 of the mounting box 20 to the surface of the prefabricated concrete layer 42 facing one side of the trolley.

Assembling process at construction site:

first, the cover 30 on the surface of the precast concrete layer 42 is opened, and the connecting section 12 bent in the mounting box 20 is bent straight, so that the connecting section 12 passes through the opening 21 to the second side 24 of the mounting box.

And then, connecting the reinforcement cage of the cast-in-place concrete 43 with the connecting section 12, pouring to form the cast-in-place concrete 43, and finishing the assembly construction of the prefabricated part 40 and the cast-in-place concrete 43 after the pouring is finished.

In the process that the prefabricated part 40 needs to be connected with the cast-in-place concrete 43, the structure and the trolley of the existing prefabricated part 40 do not need to be adjusted, the connecting piece 10 does not need to be embedded in the existing prefabricated part 40, the prefabricated part connecting device 41 can be directly installed on the reinforcement cage of the original prefabricated part 40, and the reinforcement cage after installation can be directly placed into a formwork for pouring. When prefabricated component 40 needs to be connected subsequently, the reinforcing steel bars stored in mounting box 20 only need to be restored, and then binding connection can be carried out on the reinforcing steel bars with cast-in-place concrete 43, and the surface concrete of prefabricated component 40 does not need to be chiseled. The prefabricated part 40 reduces the complexity of the production of the prefabricated part 40, improves the production efficiency of the prefabricated part 40, and simultaneously makes the installation and connection of the prefabricated part 40 and the cast-in-place concrete 43 simpler and more convenient.
