BUTT SELF-LOCKING CONNECTION OF REINFORCED CONCRETE PANELS IN COLLAPSIBLE LARGE-PANEL ENERGY-EFFICIENT BUILDINGS Russian patent published in 2024 - IPC E04B1/38 E04B1/61 

FIELD: construction.

SUBSTANCE: invention relates to construction and can be used in erection of collapsible prefabricated energy-efficient buildings from large panels, namely in connection of panels of external and internal walls and floor panels. Butt self-locking connection of large panels in collapsible energy-efficient buildings includes embedded parts located in external and internal wall panels and in floor panels, external three-layer wall panel consisting of external protective and internal bearing layers of concrete connected by means of flexible connections with shift of vertical end faces relative to each other, and a layer of effective insulation located between them, has vertical anchors in the form of truncated cones on the upper horizontal face of the bearing layer, height of which exceeds thickness of floor panels, on lower horizontal face there are cone-shaped sleeves, inner cavity of which corresponds to the height of the projecting part of the vertical anchors located on the upper horizontal face of the bearing layer of the outer wall panel after the installation of the floor panels, and in the upper and lower parts in one of the vertical end faces of the bearing layer – niches with vertical anchors in the form of truncated cones, and its other vertical end face of the bearing layer and the end vertical face of the inner wall panel in the lower and upper parts have projecting horizontal embedded plates with horseshoe-shaped projections having inner through holes in the form of a truncated cone, at that, floor panels have embedded parts in places of support on the entire thickness of the panel with holes in the form of truncated cones, wherein vertical anchors, cone-shaped sleeves and through holes in horizontal horseshoe-shaped embedded plates of wall panels and embedded parts of floor slabs have the same taper, and diameters of abutting cone-shaped elements are calculated so that when they coincide during installation, self-fixation of large panels in design position takes place.

EFFECT: improving quality, speed and accuracy of assembling large panels, reducing labour intensity of assembling and dismantling buildings, improving heat-shielding properties of joints and energy efficiency of large-panel buildings.
