BUILDING BLOCK Russian patent published in 2016 - IPC E04C1/40 

FIELD: construction.

SUBSTANCE: invention relates to structural elements in form of finished construction blocks for construction of bearing and enclosing structures of buildings and structures, and can be used for low-cost construction of pre-engineered low-rise objects with reinforced inner frame without using binding materials, hoisting mechanisms and without using skilled construction workers. Building block is made in form of panel in form of rectangular parallelepiped, consisting of three interconnected layers of two parts of panel and layer of filler between them. Both parts of panel are made in form of identical assemblies symmetrically arranged relative to horizontal axis of building block. Each assembly consists of two plates attached to each other in highest plane and parallel displaced relative to each other on both sides. Between internal plates of parts of panel at their opposite sides and flush with their outer edges there are two or more identical posts in form of rectangular parallelepipeds, oriented with their longitudinal axes parallel to vertical axis of building block. Between supports there is layer of panel filler. All parts of panels are attached to each other by means of glue or by means of fasteners. During assembly of building blocks of building structure projections formed with internal plates of opposite parts of assemblies construction unit are aligned in horizontal and vertical planes with appropriate recesses formed by outer plates of opposite parts of assemblies of building block in adjacent construction blocks, which allows construction blocks to self-center during assembly in two planes without extra appliances or auxiliary technological operations. At that, in vertical plane of post structure being built from building blocks each resting on building block of overlying stand underlying building block so that at end of vertical assembly of building structure inside it there is range of hidden multi-link vertical bearing stands, considerably increasing its load-carrying capacity, defined by the structure and material of posts.

EFFECT: low weight, ease of manipulations and simplicity of jointing of adjacent building blocks, assembly of building structures from them to carry out manually and in very short period of time.
