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.

A slab bolster upper for supporting rebar in a reinforced concrete structure while the concrete is poured and thereafter cures, is of molded plastic construction and is formed with horizontal and vertical voids that facilitate concrete placement and break up potential shear planes. Opposite ends of each unit are provided with complementary buckles to interconnect with like units to form a continuous support of desired length.

A protective cover for a reinforcing bar including a collar structure defining a perimeter portion and having an open end for receiving the end of a rebar. A cap portion is connected to the collar structure oriented substantially perpendicularly to the collar structure and including a support portion formed integrally with the collar structure. The cap portion further includes a barrier plate supported on the support portion and defining an exposed upper surface of the cover. In one embodiment, a reinforcing plate is disposed beneath the barrier cover and defines an lower surface lower surface within an area defined by the perimeter portion of the collar structure.

Chair

The present invention is an improved high chair which positions and supports reinforcement members at a desired distance from a surface. The high chair has a body with a lower base portion, an upper connecting portion and an upper support surface. One or more supporting feet are preferably attached to the lower base portion to provide for secure support of the chair on a variety of surfaces, including harder surfaces such as a concrete mold or softer surfaces such as graded soil. The upper support surface includes a support structure configured to hold the reinforcement bars in a stationary position. The upper support surface also includes a plurality of holes which allows a head piece to be mounted to the chair. The head piece allows the height of the chair to be readily adjusted.
