Description

Technical Field

[0001] The utility model belongs to the field of prefabricated beam moulds, in particular to an auxiliary tooling for arranging transverse reinforcement bars of prefabricated beams. Background Art

[0002] In the process of prefabricated beam processing, it is usually necessary to build a mold first, and then place longitudinal and transverse steel bars in the mold to form cross-sectional steel bars, and then weld the vertical steel bars to the cross-sectional steel bars to form cage-type steel bars. When building the steel bars, the cross-sectional steel bars are usually positioned by a comb plate (also called a comb plate) to facilitate the subsequent steel bar welding and construction. However, the existing comb plate is usually fixed to the edge of the outer mold by bolts, which is cumbersome to replace, and the assembly and disassembly is time-consuming, labor-intensive, and inconvenient, and the strength of the comb plate is limited.

The entire comb plate 113 is an L-shaped steel plate structure and is provided with a groove 143. The groove can carry the second annular steel bar 132 in the positioning steel bar skeleton 130, but the overall structure of the steel plate is thin and the strength is low. It is impossible to know from the full text of the comparative document whether the comb plate can be quickly assembled, disassembled and replaced. From the figure, it is more likely to be connected by welding or bolts. Therefore, the comparative document still has the problem that the comb plate cannot be easily disassembled and has limited strength.
