This disclosure refers to a metallic support for rigging used in building industry systems, comprising a steel bar provided with “C”-shaped metallic supports welded to it, in order to deliver increased mechanical resistance, leading to easier use and decreasing losses causes by damage during use or transportation.

Rebar-based support assemblies that can be fabricated without the need for on-site welding. The assemblies include a number of differing sized and shaped crimps used in place of welds to provide rebar assembly-to-rebar assembly connections. Each crimp mechanically couples two or three pieces of rebar together, such as a border bar of one rebar assembly to a border bar of an adjacent rebar assembly. Each crimp includes a body with two or more arcuate recessed surfaces each for receiving a piece of rebar. In a first configuration of the crimp, a pair of spaced-apart arms (or extending members) extend from the body and define an opening through which the rebar is passed and set into the recessed surfaces. A deformation force is applied upon the two arms to deform the body into a second configuration with the arms in abutting contact or nearly so at an outer tip or end.

A weldment that is embedded in a precast concrete building member that is used to join the concrete building member to other concrete building members. The weldment has a top plate, side plate, and outstanding top and bottom legs. The surface of the top plate and side plate are not embedded in the precast concrete building member. The legs are integrally formed with the top plate and side plate. The top plate and side plate present weldable surfaces to join by welding the precast concrete building member to another building member.

The present invention provides a prefabricated floor panel system used in stay in place formwork for pouring concrete floors. The prefabricated floor panel system includes a top and has walls depending downwardly at an upper lateral edge of the wall from each outermost lateral edge of the top, a lower lateral edge of each wall having a ledge extending outwardly away from the top. A first ledge of one prefabricated floor panel system is capable of overlying another ledge of an adjacent prefabricated floor panel system to allow for the one prefabricated floor panel system to be joined to the adjacent prefabricated floor panel system to form a channel. The first ledge of the prefabricated floor panel system is provided with a reinforcing bar spaced away from the wall and the first ledge of the prefabricated floor panel system, the reinforcing bar being supported by a plurality of a reinforcing bar chairs spaced along the length of the prefabricated panel system, the reinforcing bar chairs being attached to the first ledge or wall such that there are no significant interfering structures projecting from a lower surface of the first ledge. The other ledge of the prefabricated floor panel system is free of interfering structures above the ledge to allow the first ledge of one prefabricated floor panel system to overlie the other ledge of an adjacent prefabricated floor panel system to allow for the one prefabricated floor panel system to be joined to the adjacent prefabricated floor panel system to form a channel.

A hybrid wall reinforcement wall anchoring system is described for use in masonry cavity walls. The reinforcement and anchor is hybrid device installed within the backup wall and interlocked with novel veneer ties. The novel veneer ties are wire formatives and are manually connected and interlocked with the anchor. Once interlocked and installed within the cavity wall, lateral, vertical and front-to-back veneer tie movement is limited, strengthening the cavity wall structure. The inclusion of a reinforcement wire within the veneer tie and the exterior wall provides a seismic structure.

The invention relates to a reinforcing element (1) comprising a first (2) and a second reinforcing mat (3) having metal mat rods (6), which are welded at angles to each other at junction points (7), which reinforcing mats (2, 3) are held spaced apart from each other at a normal distance (9) by rod-shaped spacers (8) with respect to the first mat plane (4) and the second mat plane (5) of the reinforcing mats. The spacers are metal (8) and are permanently connected to individual mat rods (6) of the first (2) and second reinforcing mat (3) by welding connections (10), preferably resistance welding connections, wherein at least individual spacers (8) protrude outward at least beyond the first mat plane (4) of the first reinforcing mat (2) in a direction (11) pointing away from the second reinforcing mat (3) by a first protrusion length. The invention further relates to a double wall furnished with the reinforcing element and a method for producing the reinforcing element and the double wall.

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.

Provided are an anchor pin for placing shotcrete and fixing a textile grid and a method of constructing textile grid reinforced shotcrete using the same, wherein the anchor pin allows a textile grid reinforcement to be precisely disposed at a required position and, when shotcrete is placed, prevents a textile grid reinforcement from moving due to a driving pressure for precise construction so as to increase durability and safety of the concrete structure, allows primary and secondary shotcrete to be constructed while placing thicknesses thereof are visually checked so as to increase precision of construction, and allows the textile grid reinforcement to be disposed and fixed to accurately correspond to a shape of the concrete structure even when a lower portion of a slab, a wall, and a structure with a curved surface, such as a lining of a tunnel, are built.
