Abstract: Devices and methods for controlled dispensation are described herein where such an assembly may generally comprise an index plate having one or more protrusions extending from a surface of the plate, a first actuator configured to translate the plate in a first direction, and a second actuator configured to translate the plate in a second direction different from the first direction. The one or more protrusions may define one or more rows which are arranged upon the plate in a collinear arrangement and may further define one or more columns which are arranged upon the plate at an angle relative to a proximal or distal edge of the plate such that each protrusion is off-set relative to an adjacent protrusion along the column.

Abstract: A chair for supporting and spacing post-tension cables having a generally tapered body with an upper receiving area for securing the cables and a planar base adapted to rest on a flat support surface. The body has inner and outer surfaces that are substantially complementary to one another to allow a plurality of chairs to be stacked together. The receiving area includes posts extending upwardly between notches. The posts define passageways for guiding the cables into the notches. Detents project inwardly from the tops of the posts and fixedly retain the bars within the passageways. The chair may be formed from a resilient polymeric material.

Abstract: A brace for use in tilt-up construction is disclosed. The brace includes a bottom surface and a vertical side surface. The bottom surface of the brace is affixed to a permanent horizontal surface (e.g., a slab) in a manner that allows the brace to be removed without damaging the permanent horizontal surface. The vertical side surface of the brace is attached to a concrete pour form. The bottom surface of the brace is affixed to the permanent horizontal surface using an adhesive. Alternatively, a shoe is attached to the permanent horizontal surface and the brace sits in the shoe. A flange is releasably securable with the brace to batter the form when the flange is place in contact therewith. Alternatively, the shoe has an upwardly extending inclined ramp that is operable to orient the brace so that the vertical side surface of the brace is disposed at a battering angle to batter the form.

Abstract: A void former or dowel sleeve adapted to be encapsulated in a hardened mass of concrete, which is collapsible upon the application of a tensile force longitudinally thereof to remove the void former from the concrete and provide a void for a load transferring dowel.

Abstract: A brace for securing concrete forms to a base has first and second triangularly-shaped sidewalls and a back wall extending between corresponding side edges of the sidewalls. A peripheral flange extends outwardly from the side edges of the sidewalls and the ends of the back wall and has apertures for facilitating fastening of the brace to the concrete forms and a casting surface. Advantageously, the brace can be formed as a unitary, molded component. A battering wedge is selectively attachable to the side edges of the sidewalls and cooperates with the brace to facilitate tilting the concrete form at an angle to the casting surface. The battering wedge is selectively frangible to permit use with braces of varying size.

Abstract: In a first aspect, a plurality of slab bolster elements, each including a bolster frame member having a male connector disposed on a first end and a female connector disposed on an opposite end, with the male connector including first and second outer prongs for engaging a complementary female connector and the female connector including first and second opposing side walls with first and second transverse slats extending between the side walls so as to form a socket, the male connector further including a flexible prong extending inwardly between the outer prongs, with the flexible prong including a free inward end and a wedge element configured to resiliently contact and lockingly engage the first transverse slat of another of the plurality of slab bolster elements. In a second aspect, a continuous slab bolster assembly.

Abstract: A multi-level chair for supporting a concrete reinforcement cable at a fixed height from the bottom of a concrete form is provided. The multi-level chair comprises a body having a plurality of receptacles at different heights. Each of the receptacles is adapted to retain a concrete post-tension reinforcement cable. In one embodiment, the body of the chair assumes an inverted V-shape including a pair of legs extending downwardly from an apex. Each of said legs has multiple receptacles to support a cable at a predetermined height from the bottom of the concrete form.

Abstract: An apparatus for combining adjacent concrete slabs including a dowel, an end cap, and a side frame. The end cap has a hood defining a curved channel extending at least partially around a dowel receiving end. The side frame has at least one wire received in the curved channel. Also, an end cap having an integrally formed supporting portion including first and second wire supports for supporting substantially parallel side frame cross wires. Also, an end cap including first and second sleeves positioned along opposing tangents of the outer peripheral surface of the end cap for receiving differing portions of a side frame, and further including a resilient protrusion for receiving a further differing portion of the side frame.

Abstract: A brace for securing concrete form members to a casting surface. First and second leg members are spaced to form an angle. A bridging member extends between opposing ends of the leg members and a strut extends between the joined ends of the leg members and the bridging member. The bridging member and strut form a truss, together with raised ribs along the legs and bridging member. The brace may be molded from plastic as a one-piece structure.

Abstract: A chair for supporting wire mesh while pouring concrete slabs. The chair has a generally tapered, hollow body with a receiving area for fixedly retaining the wire mesh. The receiving area includes walls extending upwardly between notches, with the walls defining passageways for guiding the mesh into the notches. Detents project inwardly from the tops of the walls to fixedly retain the mesh within the passageways. The body has inner and outer surfaces that are substantially complementary to one another to allow a plurality of chairs to be stacked together. One or more foot members are preferably attached to the lower base portion to provide for secure support of the chair on a variety of surfaces.

Abstract: A void former comprises a core assembly having at least two body members. The body members are removably coupled together to define the desired shape of a void to be formed in a concrete slab. After the void has been formed in the concrete slab, the body members may be selectively removed from the void.
