FRAMEWORK OF BUILDING AND METHOD OF ITS ERECTION

摘要

FIELD: construction engineering. SUBSTANCE: this relates to combination prefabricated and monolithic frameworks with flat disk-type flooring. It can be used for erection of single-storied and multistoried buildings for dwelling and public buildings in various areas including seismic. Framework has sectional columns with cutouts at level of flooring and with exposing their longitudinal working reinforcement at these points. Prefabricated flooring slabs provided with outlets of reinforcement at sides are located within cells of framework and are combined together according to outlets of reinforcement by means of rods. Monolithic sections of flooring disk slab have through reinforcement passing over length and width of building. This reinforcement passes after working reinforcement of columns in their cutouts. Prefabricated slabs are provided at ends with flat welded reinforcement frameworks which are located vertically in line with rods of working reinforcement of long sides of slabs above these rods. They are connected with them by means of lateral vertical reinforcement of flat welded frameworks. Flat welded frameworks are made with loop-like protrusions of their lower and upper rods over ends of slabs with width of each section in plan up to 0.20-0.30 of slab width as from its both corners. Slots are made in middle sections of slab ends and in side faces of prefabricated slabs. Faces of prefabricated slabs are bevelled with respect to plane of slabs: over ends of slabs, faces are inclined away from slab, and over sides they are inclined towards slab. Monolithic sections of flooring disk slab between ends of prefabricated slabs are made in the form of load-bearing span-pieces in which in overlapping manner are located loop-like protrusions of reinforcement from ends of oppositely located slabs. Passing through loop-like protrusions is upper working reinforcement of load-bearing span-pieces. Lower working reinforcement of span-pieces is located under loop-like protrusions of reinforcement. Upper and lower parts of
