[0012] Preferably, the adjusting member a comprises two steel bars arranged in parallel, a mortar pad is provided at the gap between the two steel bars, and the radii of the two steel bars are different.

[0013] In actual use, steel bars of a specified radius can be selected according to actual conditions, and mortar pads can be filled in the gaps between the steel bars to form an adjustment piece a.

[0014] Preferably, the adjusting member b is a steel wedge block having a concave structure, and a filling cavity is preset inside the steel wedge block with the concave structure, and a partition is arranged inside the filling cavity for filling wood chips, and a pad is arranged on the top of the steel wedge block with the concave structure, and the top of the pad is arranged in an inclined state or in parallel.

[0015] In actual use, a partition can be set inside the filling cavity according to actual needs, and wood chips can be filled at the same time, and a pad of a specified shape can be selected according to actual needs to form an adjustment member b.

[0016] The beneficial effects of the utility model are:

[0017] When the utility model is in use, the staff can select the corresponding adjusting member a and the adjusting member b according to the actual needs, and adjust the balance between the box beam structure body and the bracket through the adjusting member a and the adjusting member b, so as to ensure the stability of the connection. The design of the two balancing mechanisms is suitable for construction sites in different environments. Such a design avoids the limitations of the user when using it, which is conducive to its popularization and use. BRIEF DESCRIPTION OF THE DRAWINGS
