Method of dry construction of prefabricated reinforced concrete building

Abstract

The existing systems of dry assembly of structures from prefabricated components still require the concreting of joints, which does not allow minimizing the number of technological processes and does not eliminate the need to wait until the concrete mixture hardens. Therefore, the period of erecting a building does not reduce significantly. The present paper describes the system of dry construction assembly from prefabricated components of reinforced concrete without application of any welding or casting-in-place while performing the above-ground works, which is feasible due to the bolt connection of all components. Since no welding or concreting is required, the duration and labor intensity of the erection process reduces. The present research is aimed at working out such a system of erecting a prefabricated building of reinforced concrete, which would allow moving away from welding and joint concreting, at the same time ensuring the structural reliability. This would reduce the duration and labor intensity of the construction process. The proposed system of prefabricated dry construction assembly of reinforced concrete structures that has a plenty of advantages by virtue of its nature can be easily implemented in low- and mid-rise residential construction and for erection of industrial, public and business buildings, buildings on railway transport intended for technical operation of Railways and maintenance of transport construction objects. Moreover, the system proposed could be a perfect choice for the erection of such temporary structures as sports facilities, hospitals, parking garages and warehouses, since it is easily disassembled.
