Description

Technical Field

[0001] The utility model relates to the field of building engineering accessories, in particular to a back rib structure common to inner corners and outer corners. Background Art

[0002] The existing aluminum mold back ribs at the positive corners of the tie rod building are composed of back ribs, angle brackets, threaded rods, nuts, and gaskets. The threaded rods are passed through the angle brackets and nuts are tightened on both sides to achieve the purpose of tightening the positive corners. However, since the angle brackets are generally connected to the back ribs by welding, the sizes of the angle brackets and the back ribs need to be designed in advance and cannot be adjusted after manufacturing, forcing the back ribs with angle brackets on the exterior wall to be determined only according to the size of the wall, and the length of the back ribs cannot be adjusted, which reduces the secondary utilization rate of the material; and, for the negative corners of the wall, the back ribs used need to be beveled, resulting in the same size, but the back ribs used for the negative corners and the back ribs used for the positive corners cannot be used interchangeably, which leads to labor costs and material production costs; in addition, when disassembling the back ribs at the positive corners, it is necessary to first unscrew the nuts and then take out the entire threaded rod before the two back ribs at the positive corners can be removed. Therefore, it has the disadvantage of inconvenient disassembly and assembly, which affects work efficiency. Summary of the invention

[0008] Both ends of the back rib 1 are processed with chamfered surfaces with an angle of 45 degrees, so that the cross-section of the back rib 1 is trapezoidal.

[0009] When installing the back rib structure at the internal corner, fit the chamfered surfaces between two adjacent back ribs 1 together to make the two back ribs 1 perpendicular to each other, then use the threaded rod 7 to penetrate between the upper and lower layers of the back rib 1 and pass through the wall panel, and finally use the nuts 8 to screw into the two ends of the threaded rod 7 to fix the back rib 1.
