It is necessary to connect them before pouring to transfer the force in one steel bar to another steel bar. The operation is complicated and reduces the connection efficiency of the joint." In combination with the use, this problem is obviously a real and difficult problem to solve.

[0031] Furthermore:

[0037] The I-beam column 103 and the mounting plate 111 are both fixedly installed on the surface of the fixing plate 201 by bolts 202. Multiple sets of fixing plates 201 are respectively fixedly installed on the end faces of the vertical precast beam column 101 and the horizontal precast beam column 102.

[0038] A plug 110 is fixed to one side of the mounting plate 111;

[0039] The two sides of the insert block 110 are designed with inclined surfaces. The connecting block 104 has a slot 109 on one side that is compatible with the insert block 110. The limiting slot 106 of the connecting block 104 is provided with symmetrically arranged screws 105. The screws 105 and the connecting block 104 are fixedly connected. The card plate 107 has a through hole that is compatible with the screws 105. The card plate 107 is inserted into the screws 105 through the through hole.
