WALL Russian patent published in 2003 - IPC

FIELD: construction industry, erection of walls of residential and public buildings. SUBSTANCE: proposed wall includes rectangular building blocks. Each block has central through hole, recesses in face surfaces and longitudinal protrusions and recesses in upper and lower surfaces. Each protrusion of upper surface of block has shape of scalene trapezium in cross-section which external side surface carries horizontal longitudinal bearing platform to accommodate overlying block and which internal surface forms open conduit of trapezoidal shape jointly with opposite internal side surface of trapezium of second protrusion and plane of upper surface of block. Internal surface of each protrusion of lower surface of block is made in the shape of double-step shoulder interacting with its steps correspondingly with horizontal longitudinal bearing platform and base of trapezium of protrusion of upper surface of underlying block. Lower surface of block and internal shoulder bordering on it with sides also form conduit of trapezoidal shape facing major base of trapezoidal conduit of underlying block with its major base and form longitudinal space with conduit of the latter. EFFECT: simplified technology of wall erection that secures more through grouting of joints, existence of clearances between protrusion and recess enables various blocks to be displaced and deviations in dimensions of blocks to be compensated by that. 5 dwg
