An adjustable concrete reinforcement assembly includes a base member having a pair of open ends and an upper axial cavity defined along the length of the base member. A pair of frame members each include a horizontal extending portion and a vertical extending portion in which the horizontal extending portions are sized to engage the upper axial cavity of the base member. A hanger member is disposed at an upper end of the vertical extending portions of each frame member; wherein the frame members are axially movable within the base member to enable a horizontal dimension of the assembly to be selectively adjusted. At least one support is further provided to receive at least one concrete reinforcement member, such as rebar. In at least one version, adjustments can be to the horizontal dimension of the frame and optionally the vertical and horizontal positioning of the hanger members relative to a concrete form.

A reinforcement arrangement and a method for producing a construction material body using the reinforcement arrangement. The reinforcement arrangement comprises a reinforcement body and at least one holding anchor unit. Each holding anchor unit is arranged or attached at the reinforcement body by a foot section. A holding section adjoining the foot section is moveable between a storage position and a function position. In the storage position, the holding section extends directly adjacent along the reinforcement body and abuts the reinforcement body at one or more locations. In the function position, a free end of the holding section opposite the foot section is larger than in the storage position. The holding section can be moved manually or self-acting from the storage position into the function position. The reinforcement body, the holding section, and the foot section are preferably embodied as textile-reinforced elements.

Disclosed is an apparatus to reduce the amount of time required to assemble an array of construction reinforcing bars wherein a consistent gap is present between the reinforcing bars and the height of the exposed end of the reinforcing bars is substantially identical while simultaneously covering the exposed ends of the reinforcing bars to prevent injuries to nearby individuals that may come into contact with the exposed ends of the reinforcing bars.

The described Concrete Form Brace With Multi-Depth Rebar Positioning is comprised of opposing attachment members, which secure the brace to the concrete form elements. The attachment members have a first top end, and a second bottom end. The corresponding bottom ends of the attachment members are connected by a spanning element, which spans the width of the concrete form. The attachment members and spanning element are further connected by a plurality of reinforcing struts. Rebar attachment means at multiple vertical depths within the concrete form are integrated or connected to the reinforcing struts to provide rebar securement means at multiple depths within the poured concrete. The preferred embodiment also features vertical spacing between horizontally placed rebar to accommodate L shaped vertical rebar placement for applications where vertical rebar is specified.

A slab bolster element includes a frame member having a male connector at a first end and a female connector at an opposite second end. The male connector includes a substantially solid insertion body with a surface having a transverse locking groove. The female connector includes a receptacle body configured to receive the insertion body of a complementary male connector, and a resiliently flexible locking tab positioned and configured to resiliently deflect to allow the insertion of the insertion body of another slab bolster element into the receptacle body, and to resiliently engage with the transverse locking groove of the insertion body when the insertion body is received within the receptacle body. The resiliently flexible locking tabs can be oriented any direction to mate with similarly shaped male connectors, and material can be strategically removed from standoffs and connectors to minimize the use of materials.

A rebar support comprising: an elongate body have a first plurality of rebar cradles disposed along its length for holding rebars in a first direction; a plurality of chairs located along a back of the elongate body, each of the chairs including at least one cradle for holding steel reinforcement members in a second direction at right angles to the first direction; and first and second complementary engagement formations located at opposed ends of the elongate body for facilitating end-to-end fastening of two or more rebar supports.

A concrete spacer for use in supporting wire mesh for pouring concrete within a mold. The spacer includes a base portion and an arm portion to offer stability. The base portion is trapezoid shaped and includes a clip for attachment to the wire mesh. The arm portion offers stability and extends opposite the base portion for attachment to the wire mesh.

The reinforcement arrangement comprises a reinforcement body and at least one holding anchor unit. Each holding anchor unit is arranged or attached at the reinforcement body by a foot section. A holding section adjoining the foot section is moveable between a storage position and a function position. In the storage position, the holding section extends directly adjacent along the reinforcement body and abuts the reinforcement body at one or more locations.

The holding section can be moved manually or self-acting from the storage position into the function position. The reinforcement body, the holding section, and the foot section are preferably embodied as textile-reinforced elements.

A telescopic bar for load transmission which, if anchored in concrete slabs, creates a support between them, forming semi-rigid joints, and prevents differential settlement of the slabs, by enabling rotation in the vertical direction about a joint axis. The telescopic bar transmits a load from one slab to an adjacent slab, ensures perfect leveling of the slab surfaces, and enables removal and reuse of the slab at a later time. The telescopic bar may be used for constructing floors of easily manufactured prefabricated materials, and creates a new paradigm for the construction of roads, seaports, airports, railways, industrial areas, etc.
