MULTI-SEATER SHAPE AND TECHNIQUE OF SHAPING PILED CONCRETE STEEL MODULES Russian patent published in 2008 - IPC B28B7/24 B28B23/02 

FIELD: construction.

SUBSTANCE: multi-seater shape for shaping long-measuring concrete steel products with a square cross-section, including piled modules, consists of moulding compartments, formed by bottom plates, lateral boards and partition walls, bordered by the turning edges of the boards on the length of the moulding compartments. In at least one of the end boards, opposite each moulding compartment, there are shaping elements, installed with provision for displacement along their axis. The working end of each shaping element, designed for making a linear mortise in the concrete at the edge of the piled module, is placed in the opening of the end board with provision for moving into the moulding compartment. The tail end of the shaping element passes through the opening in the remote element, a coaxial opening on the butt end board and is equipped with a holder, designed for fixing the position of the shaping element. The remote element is in form of detachable bars with coaxial openings on the butt end board, rigidly mounted on the outer side of the butt end board parallel to it. Each shaping element is in form of a moveable bar. The technique of shaping long-measuring concrete steel objects with a square cross-section, including piled modules, with use of multi-seat shapes, involves assembling the shapes, installing the mesh reinforcement and shaping elements in the moulding compartments, their fixing into projected positions, laying the concrete mixture, holding it until it gains stripping strength and formwork removal for the formed piled modules. Before installing the mesh reinforcement into the moulding compartments, the shaping elements are not supposed to come out from the openings on the butt end board of the shape in the moulding compartment. In that case, the shaping elements used are in the form of moveable bars with nodes. Before installing the mesh reinforcement into the moulding compartments, at the ends of the mesh reinforcement, perpendicular to its axes, there is prior fastening of end plates with openings at the centre. The opening at the centre of the end plates of the mesh reinforcements are coincided with the openings at the butt end boards of the shape and the working ends of the moveable bars are inserted through them, with insertion of the later into the moulding compartment until the nodes of the moveable bars rest against the edges of the openings of the end plates, after which the bars are fixed.

EFFECT: perfection of the technology of making concrete piles under industrial conditions; increased quality of the concrete piles, with simultaneous lowering of labour intensiveness and material losses.
