PREFABRICATED STEEL BUILDING Russian patent published in 2024 - IPC E04B7/16 

FIELD: construction.

SUBSTANCE: invention relates to construction, namely to prefabricated light construction frameless buildings. Frameless building, comprising a plurality of basic structural sections, each of a shaped metal thin-sheet main panel formed with a given section based on one basic panel element, connected to each other by means of bolts in the coating structure, as well as in conjugated with the coating and with the foundation of the wall enclosure structure from the bearing longitudinal and end walls with the vertically arranged basic structural sections, made insulated and provided with an insulating layer on the inner side of the wall enclosure, combined with the walls by means of brackets rigidly fixed to the main panels and rigidly coupled with them fixing elements, is additionally equipped with at least one wall plate made of thin sheet metal located outside the same in profile and width, on at least two mating elements along the length and transversely there are matching holes, through which by means of bolts equipped with washers, they are rigidly fixed to each other and, thus, a composite structural section of bearing longitudinal walls is formed. Overlapping is made in the form of a folding structure, which consists of a lower belt containing horizontally located beams, in the upper part of which there are braces made along the entire length through equal distances, installed at an angle to each other and grouped in pairs to form identical paired links, which vertices are connected with horizontally located beams by movable connection by means of rotary hinges, paired links with angle of inclination to different sides are grouped in pairs in nodes, forming edges of inverted pyramids, in upper belt braces belonging to neighbouring beams are grouped together, forming identical paired links, which vertices are connected to the holder by a movable joint in the form of rotary hinges, paired links with an angle of inclination to different sides are grouped in pairs in nodes, forming edges of a tetrahedral pyramid with a vertex in the node, the overlap is made with possibility of expansion-shift along guides by means of hinged connections between structural elements.

EFFECT: increased speed of building erection.
