Abstract

Abstract

High-formwork supports' collapse always occur during the construction process.Through the field investigation and measurement of the supports for 15 m high-formwork, the erection parameters of high-formwork supports were obtained.It was found that there was a larger randomness during the erection of high-formwork supports, to implement full process management for the structure erection, and ensure the consistency of actual erection parameters and special construction scheme.The results show that the stress value of the pole is less than the pre-analysis pole stress, thus reflecting that the load combination proposed by Technical Code for Safety of Coupler Stell Tube Falsework in Construction of Buildings(JGJ 130-2011) is too conservative.the stress of the bottom is greater than the top on the same pole, which proved there is some regulation in horizontal bar and vertical double bridging.The pole stress associated with the height of the frame body, the higher the height of the formwork support, the greater the difference between the bottom and the top of the stress.The results provide data for the design of formwork supports.
