METHOD FOR CONSTRUCTION OF BUILDING STRUCTURES Russian patent published in 2022 - IPC E04B2/16 

FIELD: construction.

SUBSTANCE: invention relates to the field of construction, buildings and structures from prefabricated elements with a predetermined size. The method for erecting building structures consists in using ready-made elements, namely, building blocks with through holes, reinforcing bars with threaded end sections, which are placed in the specified through holes of the blocks. For centering the blocks, centering inserts and coupling nuts-sleeves are used, which are installed on at least one of the threaded ends of the reinforcing bars, with which the blocks are pulled together. The blocks are placed in a predetermined sequence to ensure alignment between them using centering inserts and the blocks are tightened using coupling nuts-sleeves, the assembly of the building structure is performed sequentially, pulling each subsequent block to the already installed block with a sleeve nut, the centering inserts are made in the form of a separate annular insert with a through hole and two opposite ledges, having centering surfaces in contact in the assembled structure with reciprocal centering recesses with centering surfaces in blocks located coaxially with the through holes of the blocks for reinforcing bars, while the centering inserts are placed between the connected blocks with the possibility of contacting its opposite centering surfaces with the corresponding centering surfaces of the recesses of both connected blocks. Before tightening the connected blocks, the centering insert is installed around the threaded end of the reinforcing bar, mating the centering surface of its protrusion with the centering surface of the recess of the attracted block. When the blocks are coupled with a nut-sleeve, the centering insert is pressed against the block, and the centering recess of the subsequent connected block is installed on the centering surface of the protrusion of the centering insert that has already been tightened, while the coupling nut-sleeve is made in the form of a threaded sleeve, into which the subsequent reinforcing bar is screwed, onto which the subsequent building block is inserted with a corresponding hole, while holes for reinforcing bars are made in the blocks.

EFFECT: increase in structural strength, decrease in the volume of construction material.
