UNIVERSAL CONSTRUCTION BLOCK Russian patent published in 2023 - IPC E04C1/00 

FIELD: construction.

SUBSTANCE: invention relates to the field of construction, namely to the construction of building blocks or bricks, and can be used in the erection of walls of buildings and structures. The universal building block has a symmetrical H-shape and consists of two walls with holes connected by a jumper. On each wall, ebbs are made asymmetrically to each other, directed at a right angle into the block. Three pairs of vertical grooves are made symmetrically on the bridge on both sides, one pair of grooves is located in the center of the bridge, and the other two are located at the edges. Chamfers are made at the junctions of the walls and the lintel; through holes are made in the web between the vertical grooves.

EFFECT: reduction of the range of building blocks for the construction of walls due to the use of one standard size of a universal building block of a certain shape with increased voidness, mechanical strength and the possibility of dividing it into parts, which also allows it to be used for cladding and filling with thermal insulation; ensuring high manufacturability of the universal building block due to its division into separate parts (two walls with ebbs and a lintel), ensuring the construction of various masonry walls, as well as the possibility of its manufacture by various methods, including the method for plastic molding and semi-dry pressing from ceramic masses, and also by the method for vibrocompression from various masses.
