IoT enabled monitoring scheme for scaffold-frame systems for transfer plate construction

Abstract

In recent years, several collapse accidents of the falsework frame system appear from time to time during construction. However, few studies are focused on the influence of eccentric loading from uneven concrete pouring on the falsework system. Finite element software ABAQUS is adopted to calculate the static force of a typical type of falsework which is commonly applied in practice engineering. The stress distribution pattern and deformation of steel falsework are considered under two working conditions - eccentric load and uniform load. The vulnerable points and vertical deformation of the top beam on falsework are indicated in this paper. The stress distribution of falsework is briefly analyzed from three aspects: modelling, loading and calculation results. To help improve the negative influence from eccentric loading during construction, a falsework monitoring system utilizing IoT to detect and report abnormalities prior to the occurrence of an accident is proposed. The research and design of special new sensor devices, communication means and the adopted IoT means to improve safety of falsework is briefly introduced.
