A keywell form retention assembly includes post that having a bottom end and a top end. The post has a front side and a back side. A plurality of mounting holes extends through the front and back sides. The mounting holes receive fasteners to mount the post to a cement form. A sleeve is attached to the top end of the post. An arm has a first end and a second end. The arm extends through the sleeve and is movable forward or rearward through the sleeve. A leg is attached to and extends downwardly from the arm adjacent to the first end. An anchor plate is attached to the leg. The anchor plate has a mounting aperture extending therethrough to receive a coupler to engage a panel. The anchor plate retains the panel such that that panel abuts and stabilizes a keyway form.

A panel attachment structure including a panel assembly having a channel member including a channel therein. The panel assembly further includes at least one reinforcing member directly or indirectly coupled to the channel member, and an insert assembly including an insert portion. The insert portion is configured to be closely slidably received in the channel member in an insertion direction, and the insert assembly is configured to be coupled to an underlying support structure.

Concrete coupling assembly comprises a base holder for being attached to a concrete forming surface, the base holder including a central opening; a coupler having one end disposed within the central opening, the coupler having an axis for being positioned substantially transverse to the forming surface, the coupler having first and second threaded bores through the one end for attachment of a threaded rod; and a separate anchor body threadedly attached to another end of the coupler.

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.

Provided are a foundation bolt pre-embedding positioning mold and a method for mounting a foundation bolt, including a centerline positioning assembly and a vertical positioning assembly for mounting on foundation steel bar, wherein the centerline positioning assembly includes a positioning template horizontally arranged, a positioning portion is formed on the positioning template, the positioning portion extends along a first direction, the positioning portion is used to overlap with a preset centerline in a vertical direction, and the first direction is a length direction of the positioning template; the positioning template is configured to be mounted on the vertical positioning assembly, so as to fix a position of the positioning template in the vertical direction; and a first mounting hole is formed in the positioning template, so as to vertically fix the foundation bolt to the positioning template.

A panel attachment structure including a panel assembly having a channel member including a channel therein. The panel assembly further includes at least one reinforcing member directly or indirectly coupled to the channel member, and an insert assembly including an insert portion. The insert portion is configured to be closely slidably received in the channel member in an insertion direction, and the insert assembly is configured to be coupled to an underlying support structure.

A system, method and apparatus include generating a building model of a building to be constructed at a construction site, identifying within the building model positional locations for installation of one or more anchor apparatuses within structural elements of the building model, transmitting the building model to a portable computing device at the construction site and identifying the location of the portable computing device to a given positional location. At least the generating, identifying, transmitting and identifying steps are implemented via at least one processing device comprising a processor and a memory.

An internally braced permanent formwork for concrete foundation construction is provided in order to achieve a quick and simple assembly. The formwork comprises a base member laid on the ground having a perimeter recess on an upper surface for receiving components of the formwork. One or more permanent outer boards forming an outer periphery of the foundation are provided and coupled to a plurality of spaced internal bracing components to prevent collapse under the pressure of wet concrete.

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 slab anchor that is resizable in the field to accommodate different thicknesses of slabs. The anchor may have a top assembly and a bottom assembly that are joined by pipe such as widely available PVC pipe. A contractor can simply determine the desired width of the slab (which determines the height of the anchor) and cut a PVC pipe to the length necessary to make a slab anchor of the needed height. This system allows contractors to keep on hand only a single type of slab anchor, and to customize this anchor easily at the last minute for each slab. The top assembly of the anchor may have a coil that a fastener screws into after the concrete is poured; a coil protector screw may be placed into the coil during pouring so that concrete does not fill the coil, and removed thereafter to install the fastener.
