[0002] The steel reinforced concrete formwork project is very different from the reinforced concrete formwork project. Since holes are not allowed to be drilled in the steel section, ordinary tie bolts cannot be used normally, resulting in the inability to form the formwork by conventional methods. Most of the existing steel reinforced concrete formwork supports use segmented tie bolts. For example, for the tie bolt connection structure of the steel reinforced concrete formwork of Qingjian Group Co., Ltd., connecting ear plates are set on the steel column or steel beam, and the tie bolt is fixed to the connecting ear plate (Chinese Patent CN201943356U); the steel reinforced concrete formwork reinforcement structure and construction method of Guangdong Zhongnan Construction Co., Ltd. (Chinese Patent CN108005381A); these support and reinforcement methods using tie bolts have a cumbersome installation process and slow speed, affecting the construction efficiency; a concrete steel formwork support device of China State Construction Engineering Corporation, the Second Construction Company (Chinese Patent CN205955194U) consists of components such as I-beam brackets, horizontal ribs, and diagonal braces.
