发明名称 Block for retaining wall
摘要 A block for a retaining wall having a front face forming part of a visible side of a retaining wall, and a support face which supports at least one similar overlying block. The support face is angled with respect to the front face and traversed by a through opening which defines an internal abutment surface placed at a first predetermined distance from the front face. A reference element protrudes from the support face at a second predetermined distance from the front face, in order to abut, in use, against the at least one internal abutment surface of the similar overlying block and thus prevent the displacement thereof in only one of two directions which are transverse to the front face. The reference element includes a flattened engagement portion. An elongate slot is provided on the support face to receive the corresponding flattened engagement portion.

主权项 1. A block for a retaining wall, comprising a front face intended to form part of a visible side of a retaining wall and a support face intended to support and bear, in the production of the visible side, at least one similar overlying block, the support face being angled with respect to the front face and traversed by at least one through opening defining at least one internal abutment surface placed at a first predetermined distance from the front face, at least one flattened engagement plate protruding from the support face at least at a second predetermined distance from the front face in order to come into abutment, in use, against the at least one internal abutment surface of the similar overlying block and thus prevent displacement thereof in only one of two directions which are transverse to the front face, and at least one slot elongate in a direction transverse to the front face being provided on the support face to receive the at least one flattened engagement plate in order to produce a retaining wall having a configuration of the visible side selected from at least two possible configurations of that side, the at least one flattened engagement plate is upside down L-shaped and comprises a flattened leg and an outer reference portion coplanar with, but laterally protruding from, the flattened leg, the flattened engagement plate having opposite faces that are planar on opposite faces of the flattened engagement plate, each of the opposite faces including a portion of the flattened leg and the outer reference portion; the at least one slot being narrow and the flattened leg having a cross-sectional shape substantially corresponding to a cross-sectional shape of the at least one slot such that a cross-section of the flattened leg includes external surfaces that are slightly smaller than a continuous closed internal surface of the slot with substantially no space between the flattened leg and the internal surface of the slot when the flattened engagement plate is inserted into the slot.
