FIELD: construction.
SUBSTANCE: method for construction of multistore buildings of three-dimensional blocks includes floor-by-floor installation of the blocks in the design position. The three-dimensional blocks are equipped with a floor, ceiling, enclosure panels, one- or two-level bearing columns and load-bearing walls. The last are set at the factory to ensure greater stiffness of the building frame. The following blocks are mounted via the one- or two-level bearing columns with different diameters depending on the floor level. One-level and two-level bearing columns are designed as pipes filled with concrete having rigidly welded shims arranged at both ends of the pipe and which have rib stiffeners made on them to ensure the joint rigidity. There are bolt holes on the shims. Guide pins are mounted in the transition places of the concrete-filled bearing columns and on the floor and ceiling of the three-dimensional blocks. The pins are arranged according to the bolt holes on the column strips which are then interconnected by nuts. The lower flange of the three-dimensional blocks and load-bearing framed walls are designed compositional and made of steel structures in which metal ropes are placed and strung for the building structural rigidity. Mortise-tenon fastenings are installed on the face ends of the three-dimensional blocks which serve for preliminary fixation of the enclosure panels and double-glazed windows. Magnets are fixed in the load-bearing walls, enclosure panels and bearing columns for pre-guidance of the structures. The blocks are mounted with the help of stiffening beams and a telescopic lift. The enclosure panels, double-glazed windows, bearing columns of the building are installed by tower mini cranes. The installation of three-dimensional blocks in automatic mode is performed by an automated tower hoist. The installation of three-dimensional blocks in robotic mode is carried out by a manipulating backhoe and a trans-robot with GPS, GLONASS receivers and other transmitters and marks for space coordination of mounted components. The multi-store building is installed on a pre-arranged foundation.
EFFECT: invention allows increasing seismic resistance of multi-store buildings of three-dimensional blocks, decreasing labor input and costs for their erection and enhancing architectural and design posibilities.
