[0022] In the embodiments, the embedded part 1 comprises a first flat plate 11 and a second flat plate 12, the second flat plate 12 is connected perpendicularly to the bottom surface of the first flat plate 11, the first flat plate 11 and the second flat plate 12 are connected with each other to form a T shape, the support pole 2 is connected perpendicularly to the embedded part 1, specifically, the support pole 2 is connected to the top surface of the first flat plate 11, since the first flat plate 11 only supports the support pole 2 with the cooperation of the second flat plate 12, the bearing capacity is limited, therefore, some embodiments are provided, the middle of the bearing plate 4 is provided with an opening, the opening is connected with a screw rod 6 matched with the opening in screw threads, the screw rod 6 is parallel to the embedded part 1 and arranged below the embedded part 1, the side surface of the screw rod 6 is connected with a support pole 7, when the screw rod 6 is connected to the opening, the support pole 7 is below the support pole 2 and abuts against the bottom surface of the embedded part 1, when the screw rod 6 is screwed in, the top of the support pole 7 is pressed below the support pole 2 and tightly contacts the bottom surface of the second flat plate 12 of the embedded part 1, forming a three-point one-line stiffening support structure.

[0023] The T-shaped embedded part 1 itself has good bending resistance, combined with the multidirectional stress system of the screw rod 6-support pole 7, the overall bearing capacity is further improved, in the embodiments, the support pole 7 and the second flat plate 12 are below the bottom surface of the support pole 2, which can effectively avoid the early buckling of the first flat plate 11.

[0024] The connection strength of the embedded part 1 is strengthened by the screw rod 6, and the support rod 7 is used for targeted support of the support rod 2. Preferably, a nut 9 is arranged in the hole, the nut 9 is embedded in the wall body and does not contact the load-bearing plate 4, the screw rod 6 is in threaded connection with the nut 9, and the overall load-carrying capacity can be further improved.
