[0029] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0030] like Figure 1-Figure 7 As shown, a back rib structure for wall support includes a template 2 arranged on the outer surface of the wall 1, and a plurality of straight back ribs 3 are arranged on one side of the template 2, the template 2 is located between the straight back rib 3 and the wall 1, the plurality of straight back ribs 3 are arranged in sequence along the circumference of the wall 1, and the plurality of straight back ribs 3 are connected end to end in sequence, and a plurality of first back ribs 4 are also arranged on the template 2, the first back rib 4 is located on one side of the straight back rib 3, the first back rib 4 is detachably connected to the straight back rib 3 through a height difference platform 5, the first back rib 4 and the straight back rib 3 have the same structure, the straight back rib 3 is a square tube, and a plurality of connecting holes 31 are arranged along the axial direction on the straight back rib 3, as shown in FIG. Figure 1 As shown, it can also be formed by welding two square tubes side by side. The straight back rib 3 of this embodiment is formed by welding two 40*60*2.5mm square steel tubes side by side. The main function is to ensure the straightness of the wall surface. The back rib structure can be applied to different working conditions using only one back rib specification. When the back ribs need to be connected or connected in series, other standard accessories can be selected to complete it. All of them are installed on the back ribs for easy operation by the staff, simple construction, and few construction parts.

[0031] The two straight back ribs 3 are connected by a connecting member 6. The cross-section of the connecting member 6 is a U-shaped structure.

[0036] Two adjacent straight back ribs 3 or two first back ribs 4 are connected by an angled clamping piece 9, which is arranged at the corner of the wall 1, and each straight back rib 3 or first back rib 4 is equipped with an angled clamping piece 9, the cross-section of the angled clamping piece 9 is a U-shaped structure, the outer periphery of the straight back rib 3 or the first back rib 4 is located in the U-shaped structure, one end of the angled clamping piece 9 is provided with an oblique cut, two angled clamping pieces 9 are arranged opposite to each other, and the two oblique cuts are matched, and a fifth through hole is provided on the angled clamping piece 9, and a fifth positioning bolt passes through the fifth through hole and the connecting hole 31 respectively to fix the relative position of the angled clamping piece 9 and the straight back rib 3 or the first back rib 4. The angled clamping piece 9 is usually used for the inner corner of the return wall. The inner corner of the return wall may move inward due to the side pressure of the concrete. In this case, the use of the inner corner connector 7 will squeeze the inner corner due to excessive stress and cannot be removed from the wall.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
