Description

TECHNICAL FIELD

[0001] The utility model belongs to building connecting equipment technical field, more specifically, it relates to a kind of multidirectional connecting piece of intelligent mould platform. BACKGROUND

[0002] Air building machine is a new construction technology that has gradually emerged in the field of construction engineering in recent years, and its core concept is to significantly improve the construction efficiency through mechanization and automation, and to realize the 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 development 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 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 structure on the main frame. Reinforcing devices are installed on the main beams, which include a support, a steel wire rope, an ear plate and a tension sensor.
