    摘要: A retaining wall block having a false joint and a system of retaining wall blocks. The retaining wall block includes a body having a first textured surface and a second textured surface and a false joint dividing the first and second textured surface. The false joint can have a depth divided by the width greater than two inches. The false joint can have an interior angle of less than ten degrees. The system includes a plurality of retaining wall blocks and a first course of retaining wall blocks engaged with a second course of retaining wall blocks below. Each block in the system comprising a front face having a first textured surface and a second textured surface and a false joint dividing the first and second textured surface. The false joint can extend a predetermined depth of a third surface.

    摘要: A form for forming a modular pavement slab with long and short cavities alternatingly formed around its periphery includes a header and a plurality of short and long forming tools. The header includes an inner vertical surface that defines a portion of the periphery of the modular pavement slab. The short forming tool includes an elongate body defining a longitudinal axis and having a proximal end positioned against the inner vertical surface of the header. The elongate body has a longitudinal bore therethrough and a riser bore defining an axis that is noncollinear to the longitudinal axis. A riser is releasably coupled to the riser bore. The long forming tool is substantially similar to the short forming tool. The elongate body, however, is longer than the short forming tool and includes two riser bores. A riser is releasably coupled to each respective riser bore.

    摘要: A method for manufacturing a curable light-conducting body (21) in a casting method, in particular for the manufacture of light-conducting bodies (21) of a curable concrete material (36, 56), wherein a light-conducting mat (1) is embedded in a curable casting material (36, 56), and a casting mold (27) with a recessed mold cavity (18) open at the top is filled with the not-yet-cured casting material (36, 56), wherein, in a first method step, a plurality of molding punches (32) moveably arranged in the mold cavity (18) of the casting mold (27) are moved to at least the plane of the upper edge (43) of the mold cavity (18), 1. in a second method step, the space between the molding punches (32) in the mold cavity (18) is filled with a curable casting material (36), 2. in a fifth method step, the light-conducting mat (1) to be embedded in the casting material (36, 56) is placed on the end sides (61) of the molding punches (32) raised in the mold cavity (18), 3. and that, in a sixth method step, the light-conducting mat (1) is pressed into the casting material (36, 56) wherein, with the pressing movement of the light-conducting mat (1) into the casting material (36, 56), the molding punches (32) are approximately synchronously moved downwards out of the bottom surface of the mold cavity (18).
