A prong is configured for use with a concrete reinforcement element and includes first and second legs positioned opposite first and second sides of the prong and a bridge portion connecting distal ends the legs, where the bridge portion forms a first end of the prong. The legs extend from the bridge portion to a second end of the prong opposite the first end, and each of the legs has a proximal end at the second end of the prong. The proximal end of the first leg is bent toward the second leg, and the proximal end of the second leg is bent toward the first leg, such that the proximal ends of the legs overlap each other. Inner surfaces of the proximal ends of the legs define engagement surfaces configured to engage a tie wire, enabling the proximal ends to be connected to the tie wire.

Stay-in-place forms and methods and equipment for installing thereof. A concrete form includes a vertical component and a horizontal component, the vertical component located substantially perpendicular to the horizontal component. Also, the form includes an interior surface, at least a portion of the interior surface providing a form for supporting uncured concrete; wherein the uncured concrete forms a concrete structural portion upon curing of the uncured concrete; and wherein the interior surface remains attached to the concrete structural portion after curing. The form may include inserts and compatible form attachments. Also, forms including recesses may be utilized to reduce the weight thereof. Lifting equipment and accessories may be utilized to lift the form from a form holder and set same in place. Forms contain the work area as soon as it is installed to minimize fall hazards and the time, costs, and downtime associated with installation of safety measures.

A system for providing reinforcement to structures comprises a prefabricated rebar assembly, a first end plate and a second end plate. The prefabricated rebar assembly comprises multiple rods connected to each other. The prefabricated rebar assembly is held between the first end plate and the second end plate to form a block of rebar assembly.

Digital flexural materials are kits of discrete parts that can be assembled into a lattice structure to produce functionally useful assemblies. Digital flexural materials enable design of materials with many small and inexpensive flexures that combine in a lattice geometry that permits deformation without compromising the strength of the assembly. The number of types of parts in a kit is small compared to the total number of parts. A product constructed from digital flexural materials comprises a set of discrete units that are assembled into the structure according to a lattice geometry, with a majority of the units being reversibly connected to at least two other units in the set according to the lattice geometry, and wherein, in response to loading of the structure, a reversible deformation of at least part of the structure occurs. An automated process may be employed for constructing a product from digital flexural materials.

A self-furring welded wire mesh for reinforcing generally planar concrete and stucco structures is formed of a matrix of longitudinally and transversely extending wires disposed about a first common plane and welded together at their intersections. A selected plurality of the longitudinally extending wires each define a plurality of generally V-shaped spacing furrs therein extending generally perpendicular to the first plane with the bottoms of the furrs being disposed in a second plane spaced from the first plane a distance substantially equal to one-half of the predetermined thickness of the concrete panel. The spacing furrs in the selected longitudinally extending wires are located so as to be longitudinally and transversely staggered along the mesh. The spacing furrs are formed by pushing portions of the selected longitudinal wire perpendicular to the axis of the wires while holding an upstream portion thereof in a fixed disposition so as to form these without damaging or thinning the wires along the spacing furrs.
