COMPOSITE WALL Russian patent published in 2008 - IPC E04B2/14 

FIELD: construction, particularly civil and industrial buildings, namely built in earthquake territories.

SUBSTANCE: composite wall comprises triangular blocks with two flat parallel support surfaces and side surfaces transversal to support ones. The blocks are laid so that alternating rows are created. Support surfaces are made as right-angled isosceles triangles of three dimension-types, which provide basic block, basic block half and basic block quarter. Composite wall corners are formed of alternating support surfaces of basic block and basic block quarter laid one onto another so that right angles face outside. Walls are created of basic block halves laid in alternating rows so that right angles thereof are oriented in different directions. Door and window openings are created of block half and block quarter. Support surface of any block has at least one through orifice so that orifice axis is in center of triangle attitude drawn from right angle thereof. Support surface has projection opposite to valley made in another surface. To construct walls having different thicknesses blocks having corresponding dimensions are created, wherein basic block half triangle attitude is equal to wall thickness or wall thickness is divisible by said triangle attitude. To increase block connection minimal necessary number of orifices for reinforcement bars receiving is formed in the blocks, wherein orifice coordinates are defined by dividing of support surface of each separate triangular block into smaller ones by lines drawn from right angle. Orifices are arranged in centers of said lines, which divide triangular block into said smaller ones. To increase block strength each block may have reinforcing grid. In particular cases, for example in the case of relatively small distance between window or other openings, blocks of other triangular shapes, for example unequal-sided ones, are used.

EFFECT: decreased weight and increased erection speed, possibility of wall usage in earthquake territories.
