[0002] Air building machine is a new construction technology that has gradually emerged in the field of construction engineering in recent years. Its core concept is to significantly improve construction efficiency through mechanization and automation, and to achieve rapid construction of high-rise buildings and complex structures. The research of this technology involves multiple disciplines, including mechanical engineering, automation technology, construction engineering and robotics. At present, the technology of air building machine is still in the research and development stage, and has not been widely applied in large-scale construction projects. Most of the technology is still in the laboratory or small-scale prototype testing stage. Due to the lack of technology maturity, high equipment research and maintenance costs, and relatively general intelligence level, the improvement design of air building machine is particularly urgent, so it is particularly important to carry out research on intelligent mould frame platform.

[0003] The existing Bailey frame connection mainly relies on bolt connection, by setting bolt holes at the nodes, using high-strength bolts to fix adjacent Bailey frame units together. The Chinese patent application with document number CN109518813B discloses a reinforced standard Bailey frame assembly type jacking formwork platform, which is composed of a main beam, a secondary beam and a peripheral frame formed by mutual assembly of multiple standard Bailey frames. The main beams are connected longitudinally and transversely by Bailey frame connectors to form a main frame, and the secondary beams are connected longitudinally and transversely to form a truss platform frame structure on the main frame. Reinforcing devices are installed on the main beams, which include supporting members, steel wires, ear plates and tension sensors. The supporting members are vertically installed at the bottom of the lower chord of the Bailey frame of the main beam, and the ear plates are symmetrically installed at the bottom of the column head of the two ends of the main beam. The two ends of the supporting member are connected to the ear plates through steel wires. Tension sensors are symmetrically installed on the steel wires on both sides of the supporting member.

[0004] Although the above-mentioned patent realizes the reinforcement of the top formwork platform without changing the structure of the top formwork platform, the connection mode of each component is simple in structure and convenient to install, but in the high-altitude operation environment, the connection mode between components is mainly through bolts, which can easily lead to the problem of excessive number of bolts, and the tightening and disassembly of the bolts require a large amount of manual operation, which reduces the construction efficiency and may also cause potential safety risks. Therefore, there is an urgent need for a Bailey frame connecting piece that matches the application scenario of the intelligent mould frame platform steel platform. UTILITY MODEL CONTENTS
