The present invention provides a fixture with which a plurality of grids can be definitely constructed in a short period of time even by an inexperienced worker without causing the worker to do heavy work. In substantially center positions in the lengthwise direction of bottom portions of first frame members, a pair of third frame members included in connecting means are provided. In the third frame member, a base portion is caused to stand on a bottom portion of the first frame member. One of arms of a U-shape of the base portion works as a holding portion included in the connecting means, and the end of the holding portion is bent inward of the base portion to form a connection bent portion having a function to engage with a circumferential surface of a vertical wire material or a lateral wire material of a second welded wire mesh, and a function to prevent the vertical wire material or the lateral wire material of the second welded wire mesh from coming off from the connecting means.

Systems and methods for forming insulated sandwich walls are provided. Outer and inner support members are located between inner and outer strongbacks. Structural material for an outer wall, such as concrete, is deposited between the outer strongback and outer support member. Structural material for an inner wall is deposited between the inner strongback and inner support member. An insulating material is deposited between the outer and inner support members to form an insulating core.

The present disclosure provides a concrete structure strengthened using a grid reinforcement material and non-shrink grout and a method of strengthening the same in which, when strengthening a concrete structure such as a concrete slab or a concrete wall body that is damaged or deteriorated, a grid reinforcement material is mounted on one side of the concrete structure, a formwork is formed on an outer side of the grid reinforcement material to have a required gap, and then the gap is filled with non-shrink grout so that the non-shrink grout is cured therein to strengthen the old concrete structure, thereby being able to automatically fill and repair cracks formed in the concrete structure just by injecting the non-shrink grout without separately performing crack repair on the old concrete structure. Also, the grid reinforcement material may be easily fixed or mounted using a grid fixing device and may be easily applied to strengthening of a concrete structure having a curved surface as well as a concrete structure having a flat surface such as a concrete slab or a concrete wall body. In addition, reinforcing bars may be additionally arranged in a gap between a surface of the concrete structure and the grid reinforcement material so that the grid reinforcement material increases a cover thickness, and thus the concrete structure is remarkably strengthened.

The disclosure relates to an apparatus (1) for applying a hardening building material against a formwork (2) for manufacturing a solid, load-bearing construction (3), for example a wall of a building, having at least one spray nozzle (4) for spraying the building material in a spraying direction (5), a manipulator (6) which guides the at least one spray nozzle (4) and provides the spraying direction (5), wherein the manipulator (6) is mounted on a movable carriage (7), wherein the formwork (2) is formed by a formwork panel (8) which can be moved together with the carriage (7) and is positioned relative to the spray nozzle (4) in the spraying direction (5) and is oriented substantially transversely to the spraying direction (5). The disclosure also relates to a recess formwork system (25), a reinforcement mat (46), a fastening element (51) and a method for manufacturing a solid, load-bearing construction (3), for example a wall of a building, from a hardening building material.

The disclosure presents a composite column formwork which utilizes a fiber reinforced polymer (FRP) stay in place container which incorporates horizontally coplanar support chairs bonded to the interior surface, closed ties bonded to the support chairs and a plurality of longitudinal rebar enforcements bonded to the closed ties. All of the components in a preferred embodiment are formed of a fiberglass material.

A system including a reinforcement positioner having a body with a longitudinally-extending spine and a plurality of legs coupled to the spine along a length thereof and at least partially extending away from the spine. The positioner further includes an opening or recess positioned in the body, and a clip configured to be received and retained in the opening or recess.

The disclosure presents a reconfigurable composite floor formwork which defined by a plurality of interlocking fiberglass panels formed into profiles which may be moved and adapted to provide a concrete form for a floor or ceiling. All of the components in a preferred embodiment are formed of a fiberglass material.

A concrete chair elevates rebar above an underlying surface. The chair includes a rectilinear rim having a length, width and height of different distance. The rim may be oriented so each side abuts the underlying surface so rebar can be supported at three different heights above the underlying surface. In a foundation pour, the chair supports rebar at three different elevations. In a tilt wall pour, the chair supports rebar at three different elevations and produces a mark on the cured wall of considerably reduced extent.

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.
