COMPOSITE BEARING BLOCK AND FIELD CONNECTION OF BEARING BLOCKS OF PREFABRICATED BUILDING STRUCTURE Russian patent published in 2014 - IPC E04C1/00 E04B2/08 

FIELD: construction.

SUBSTANCE: invention relates to erection of engineering structures with a bearing frame in the form of prefabricated composite structures with a shell, slab or shell and slab bulky structure. A composite bearing block of a prefabricated building structure represents a factory-built assembly element in the form of a spatial polyhedron or its fragments with faces of constant, piecewise-constant and alternate thickness, possibly, with through holes in faces for letting through personnel or communications, including concrete, reinforcement, embedded parts in the form of hollow tubular elements forming also through holes in faces, serving to connect bearing blocks to each other or to other structures of the facility with application of closing elements inserted in process of installation into coaxially arranged embedded hollow elements of touching faces. The block is made with closed or with opened cavities limited by diaphragms or protruding ribs, with opened, fully or partially closed one- and multi-link transverse cross sections or in the form of fragments, at least from one thick-walled shell or slab, and surfaces of external faces, internal cavities, ribs and diaphragms are given geometric shapes from a combination of flat, curvilinear or spherical surfaces, and also it has such geometric dimensions of connecting holes and such coordinates of location of such holes in joined blocks, which as a result of assembly provide for formation of a prefabricated building structure with required dimensions and specified spatial bulky structure of bearing faces, cavities and channels, and embedded tubular elements of faces are rigidly connected to additional reinforcement embedded parts, attached to them at the external side and embedded into concrete in process of factory manufacturing of a bearing block in a curb. Also the field connection of such blocks is described.

EFFECT: increased rates for erection of cost-effective materials of building structures in a bulky, including cellular one, facility with application of rigid and manufacturable field connections of blocks, provision of bearing capacity, durability and, if required, tightness of created structures, and also improvement of technology of assembly of prefabricated reinforced concrete building structures.
