[0007] On the basis of the above technical solution, the utility model can be further improved as follows.

[0008] Further, the suspension assembly includes four reinforcing plates, and the four reinforcing plates are arranged near the other two sides of both sides of the material injection groove.

[0009] The beneficial effect of adopting the above further solution is that the reinforcing plates can facilitate the function of support and fixation.

[0010] Further, circular openings are provided on one side of each of the four reinforcing plates, and two connecting columns are connected to one side of each of the four reinforcing plates through the four circular openings.

[0011] The beneficial effect of adopting the above further scheme is that the provided circular openings can facilitate the passing of the connecting columns, and the connecting columns can facilitate the lifting and moving of the hanging device.

[0012] Further, threaded strips are provided on both sides of each connecting column, and nuts are provided on the outer surface walls of each threaded strips.

[0013] The beneficial effect of adopting the above further scheme is that the provided threaded strips can facilitate the screwing of the nuts into and fixing on both sides of the connecting column, and the nuts can facilitate the restriction of the moving position.

[0014] Further, injection ports are provided near both sides of the top of the sealing plate, and two mounting plates are provided at the other two sides of the injection groove.

[0015] The beneficial effect of adopting the above further scheme is that the provided injection ports can facilitate the pouring of concrete, and the mounting plates facilitate the connection and fixation of both sides of the injection groove.

[0016] Further, mounting openings are provided on one side of each of the four mounting plates, there are multiple mounting openings, and the multiple mounting openings are arranged in a linear equidistant array on one side of the four mounting plates.

[0017] The beneficial effect of adopting the above further scheme is that the mounting openings can facilitate the mutual connection and fixation of the precast beams, and are fixed by screwing bolts.

[0018] Beneficial effects: By using the connecting steel bars inside the communicating opening and the connecting plates can be inserted at the socket, the concrete structure poured into the injection groove can be more stable. The connecting steel bars can connect and weld the two sides of the precast beam to enhance the stability. Using the hanging assembly facilitates the handling and installation by personnel.
