COLLAPSIBLE BUILDING STRUCTURE OF FRAME TYPE Russian patent published in 2025 - IPC E04B1/342 

FIELD: construction.

SUBSTANCE: invention relates to construction and can be used in simple and relatively fast erection of low-rise buildings. Collapsible building structure in the form of a volumetric sectional frame contains combined power extended elements of a unified type, which are divided into upper and lower ones, between which there are support intermediate ones, each of which is made in the form of a composite object, including a centrally located hollow metal frame and a core, at that, the hollow metal frame, on at least two sides, is fitted by joined to each other, made of a polymer or wood material, outer parts, said frame at the ends serves as seating recesses for the mating fixed fastening sections of said upper and lower power extended elements to enter them, separate combinations of the first of which and between each other of the second of which form comparable structures separated from each other, power extended elements of which consist of having said mating, oriented up/down, fastening sections of nodal connections of metal bearing core, wherein said separate assemblies are formed by laid power extended elements so that contours of said structure are defined by alignment between each other along end parts of longitudinally and transversely arranged power extended elements, part of which is not involved in the direct formation of the contour is located inside it along the length or width of the structure, superimposing with each other and/or with said contour longitudinally and transversely arranged power extended elements, wherein said alignment is provided by mating fastening sections of said nodal joints arranged at ends and sides.

EFFECT: simplified operation and higher reliability.
