DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 to 3 , in the embodiments of the present utility model, an adjustable embedded fixing part for the steel-concrete joint includes an embedded frame 1. The bottom end of the embedded frame 1 is connected with an embedded support. Near the top end of the inner cavity of the embedded frame 1, an adjusting support is connected. A plurality of splicing blocks 2 arranged equidistantly around the circumference of its central axis member are slidably installed on the adjusting support. A through threaded hole 3 is opened in each group of splicing blocks 2. A rotating member for controlling the simultaneous movement of a plurality of splicing blocks 2 on the sliding support is rotatably installed at the center of the embedded frame 1.

[0022] When the embedded fixing part is buried into the concrete, both the embedded frame 1 and the embedded support are buried into the concrete. The top end of the embedded frame 1 faces the outside of the concrete member. When the steel structure member needs to be assembled with the concrete with embedded parts, after the installation hole is provided at the end of the steel member and is opposite to the threaded hole 3 in the splicing block 2, the two are assembled with bolts, and the position of the splicing block 2 is adjusted by the rotating member. A plurality of splicing blocks 2 arranged equidistantly around the circumference of its central axis member are convenient for assembling steel members such as round pipes and square pipes of different sizes, so that a certain support strength is maintained at the connection between the members.

[0023] In one embodiment, specifically, the adjusting support includes a connecting ring 4 located at the center of the embedded frame 1. A round rod 5 that slidably penetrates the splicing block 2 is welded between the outer ring of the connecting ring 4 and the inner wall of the embedded frame 1. A reinforcing plate 6 rotatably connected to the rotating member is welded to the bottom of the connecting ring 4. The overall support strength of the adjusting support is high and the stability is strong. Further, two parallel round rods 5 are slidably penetrated through each group of splicing blocks 2, which can conveniently further improve the support strength of the embedded fixing part. A through threaded hole 3 is opened at the center of each group of splicing blocks 2. Among them, two first fixing blocks 12 hinged to one end of the movable rod 9 are welded to the outer ring of the movable block 8, and two second fixing blocks 13 hinged to the other end of the movable rod 9 are welded to the bottom of the splicing block 2, which is convenient for the assembly between the members.

[0024] Correspondingly, the rotating member includes a control screw rod 7 rotatably connected to the inner wall of the embedded frame 1. A movable block 8 is threadedly connected to the control screw rod 7. The outer ring of the movable block 8 is connected to the bottom of the splicing block 2 through a movable rod 9. Rotating the control screw rod 7 drives the movable block 8 to move, and the movable block 8 drives the splicing block 2 to slide on the surface of the round rod 5 through the movable rod 9. Further, the top end of the control screw rod 7 extends into the inside of the connecting ring 4 and is welded with a turntable 10. A hexagonal groove 11 is formed inside the turntable 10, which can facilitate the staff to flexibly rotate the control screw rod 7 by using tools.

[0025] In one embodiment, specifically, the embedded bracket includes four groups of embedded rods 14 welded to the bottom of the embedded frame 1 and arranged at equal intervals in a circumferential manner around its central axis. The bottom ends of the four groups of embedded rods 14 are all welded to the same group of cross rods 15. The embedded rods 14 are fixed inside the concrete material to increase the fixing depth of the embedded parts. The overall fixing strength of the embedded fixing parts is high, and there are cross rods 15, which can further improve the support strength of the embedded fixing parts, etc. An outwardly turned retaining ring 16 is provided at the top end of the embedded frame 1, which can facilitate the overall embedding of the embedded parts into the concrete.

[0026] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
