Abstract
A concrete block for the construction of retaining walls molded in a vertical position. The block having a width formed between a base and a forming shoe, a height formed between fixed opposite walls of a mold. The mold includes a mobile base member, a mobile intermediate closed form and a mobile top member. The mobile intermediate closed form is positioned on the base member to receive concrete therein and the top member is positioned on the intermediate closed form. A method for molding a concrete construction block for the construction of retaining walls in a vertical position, comprising providing a base and a shoe form, sitting a fixed closed form onto the base, molding concrete into the fixed closed form onto the base, and unmolding;
Claims34
A precast block for the construction of retaining walls molded in a vertical position, said block comprising a width formed between a base and a forming shoe, a height formed between fixed opposite walls of a mold.
A concrete block comprising:
- a top face and a bottom face of a generally trapezoidal shape, said top face and said bottom face having a width decreasing from a nominal width w of said block at a rear end surface thereof to a reduced width w′ at an edge of a rim extending to a front end surface of said block and having a length corresponding to said nominal width w of the block.
A precast block according to clam 13, wherein said two adjacent blocks are columns of adjacently mounted blocks 30 are in contact only at a location of their respective said rims and at a point at their respective near end surfaces.
A mold for molding block, said mold comprising:
- a mobile base member;
- a mobile intermediate closed form for positioning on said base member so as to receive concrete therein, said intermediate closed form including opposite walls;
- and
- a mobile top member opposite said base member for positioning on said intermediate closed form so as to apply pressure to concrete contained therein;
- whereby, when said intermediate closed form is positioned on said base member and contains concrete therein with said top member positioned thereon and when the concrete cools down, concrete blocks are formed of a width defined between said top member and said base member and of a height defined by said closed form opposite walls.
A method for molding a concrete construction block for the construction of retaining walls in a vertical position, comprising
- (a) providing a base and a shoe form;
- (b) sitting a fixed closed form onto the base;
- (c) molding concrete into the fixed closed form onto the base;
- and
- (d) unmolding.
