Prefabricated buildings made of block modules with nonremovable formwork

Abstract

Introduction. The construction technology of prefabricated buildings, along with the high quality of construction, is widely used for all types of buildings and structures.Aim. To maximize the safety of people and equipment after impact. This is achieved by:1) development of a design solution for a thin-walled plate-membrane capable of obtaining significant deflections without collapse;2) technologies for assembling spatial block modules made of membrane plates without welding;3) working out technological issues of manufacturing plates-membranes; assembly of block modules; sealing joints between block modules.Materials and methods. In the manufacture of membrane plates, fine-grained concrete of the VSM B25 P2 F200 W4 brand was used with the use of a fine additive (barite), spiral reinforcement of spring wire d = 1.6 mm.Results. The proposed design solution has significant reserves of strength and deformability. This ensures the safety of people and equipment.Conclusions. The use of spiral reinforcement makes it possible to manufacture thin-walled structures with the further construction of block modules with them and, after filling with light concrete, to obtain prefabricated buildings and structures that can withstand significant loads by external shock forces.
