According to the statistical results of accident cases of housing and urban and rural construction departments, although a plurality of safety management files are provided in recent years, the number of collapse accidents of tall and big template supports is reduced, but major safety accidents still occur every year. If the flower bed is 1 month and 25 days in 2019, the flower bed collapse accident happens to 5 dead people and 5 seriously injured people in the garden household goods market in Dongyang city in Jinhua city, Zhejiang province; 6, 9 days in 2019, and the second-phase project of the second-class of the heyday city in the Bijie area of Guizhou province, the collapse accident of the template support occurs, 2 deaths occur, and 3 severe injuries occur. Therefore, a modern information technology is introduced in the aspects of high formwork design, construction and monitoring, and the technical level of construction safety management is inevitably improved.
Common formwork supports include a fastener-type steel pipe scaffold, a door-type steel pipe scaffold, a bowl-type steel pipe scaffold, a socket-type disc-type steel pipe scaffold, a socket-type wheel-type scaffold, a socket-type keyway-type scaffold and the like. The fastener type steel pipe scaffold is still the most widely applied formwork support frame in domestic construction engineering at present due to large market supply quantity, low price and flexible operation.

In developed countries such as europe, the fastener type steel pipe scaffold has been eliminated; the template collapse accident caused by using the bracket in China occurs at present. The bowl-buckled steel pipe scaffold and the socket-type disc-buckled steel pipe scaffold are large in steel amount, high in price, complex in construction, large in labor and limited in application range. Therefore, the popularization of a novel template bracket which is safe, reliable, advanced in technology, economical and reasonable in China is more urgent.
