[0002] In the construction of concrete walls and columns, it is necessary to first build the casting formwork, and then reinforce the casting formwork through structures such as secondary keels and reinforcement back ribs to ensure the final designed forming effect of concrete casting. In the existing construction process, our company combines square pipes with screw rods and inner support round pipes to form reinforcement back ribs, and sets them in pairs. In order to ensure the use stability of the reinforcement back ribs, at the external corner, two sets of perpendicular reinforcement back ribs need to be further reinforced and fixed. The existing reinforcement and fixing method is to tighten and reinforce them through two split sleeves and the sleeve structures on the two sets of reinforcement back ribs. However, its structure is relatively bulky and has a high self-weight. It is not only difficult to reduce the overall weight of the external corner fixing piece of the built reinforcement back ribs, but also not conducive to transportation. Therefore, our company continues to research and design in order to design a product with a more compact structure and lower weight. Utility Model Content
