Abstract
The object of the study is reinforced concrete modules used for high-speed construction of low-, medium- and multi-storey buildings and structures for various purposes. The subject of the study is the forces in the nodes of slinging of reinforced concrete modules. A sample with the distribution of forces of five hundred modules is taken to analyze the nature of force distribution, It’s sample is realized according to the patented technology of Group of companies “MonArch”. The sample was analyzed by the Brandon’s method. Analytical determination of forces in slinging node0s of the selected module was carried out by approximate method – by cargo areas. The character of the actual distribution of forces is conditioned by the sling length obtained as a result of the slinger’s adjustment, as well as by the difference between the tempering and design strength of concrete of the module load-bearing structures. According to the results of the calculation it was obtained that the most loaded are the corner nodes of slinging. Properly selected and adjusted length of slings allows to distribute forces more evenly over the structure and avoid overstressing of individual structural elements of the module.
