FACING BLOCK-ANCHOR FOR MORTARLESS BRICKWORK OF BACK WALL AND BACK WALL Russian patent published in 2008 - IPC E02D17/20 E02D29/02 

FIELD: construction.

SUBSTANCE: facing block-anchor for mortarless brickwork of the back wall in the form of a parallelepiped which upper face of the front surface contains a land for levelling by the lower edge of the higher situated block-anchor during its installation at the back wall. The block-anchor is made with vertical through channels in it and with a lateral gutter at the side of the upper surface of the block-anchor for the situated in it manifold with gutters and cogs for fixation to it of a net for soil reinforcing from polymer material. The depth of the lateral gutter is equal or more than the thickness of the manifold with the net. In the block-anchor there are holes for installation of connecting pins into it, some part of them are made dumb for providing a support for the pins during installation of blockes at the back wall, and the other part is performed through and dislocated relative to the dumb ones towards the facia of the block-anchor, and at the back side of the block-anchor cambs are made complete with the block-anchor and located in cantilever fashion at the both side ends, partially divided from it from the outside and the inside formed in one single vertical plane by technological gutters, providing the possibility of controllable disassembling of the cambs. Situated inside the block-anchor technological gutter is formed from the side of the through channel of the block-anchor made as an open cavity from the side end of the block-anchor, which size in the direction of the block-anchor rear side exceeds the respective size of the cavity of the through channel situated between the specified through channels having open cavities from the side ends of the block-anchor. The side ends of the facia limiting the specified open cavities are made at their height with the bevel formed by a vertical plane passing through the edge of the guiding bevel and through the outer or inner technological gutter. The back wall from facing block-anchors is described in the same way.

EFFECT: creation of reliable connection of the elements of the back wall and reduction of labour costs and materials consumption of the structure.
