The invention relates to L-shaped sheet metal parts 21 with an angled longitudinal recess 23 as well as a reinforced concrete/prestressed concrete component with at least one upper and at least one lower longitudinal reinforcement layer and a shear force reinforcement guided in its dimension over the upper-most and the lowermost longitudinal reinforcement, which is formed from the L-shaped sheet metal parts 21 according to the invention with stirrups 30 fastened in the longitudinal recess 23. The reinforced concrete/prestressed concrete component according to the invention is suitable for increasing the punching shear resistance in the region of slab columns of flat slabs.

A system for supporting and holding in place an object (for example and not by way of limitation, anchor bolts, steel plates and the like) to be embedded in concrete. A device having a shaft and a tower can be used to support the object, by inserting the shaft into an opening in the tower and rotatably locking the shaft in place at the desired height, an embed can be supported in the desired position. Concrete can be poured around the support to embed the object at the desired position within the concrete.

A reinforcement member is used with an insulated concrete ledge form including a straight inner form wall, a sloped outer form wall defining a longitudinal slot for receiving an elongate rebar member parallel to the inner form wall, and a plurality of form ties connected between the inner and outer form walls across a main concrete receiving cavity, in which each form tie defines at least one rebar chair for connection to a rebar member. The reinforcement member has i) a bridge portion to extend laterlly from an inner end to an outer end, ii) a hook portion depending from the outer end of the bridge portion so as to extend over and hook onto the elongate rebar member; and iii) a seat portion depending from the inner end of the bridge portion for mating connection with a respective rebar chair of a respective one of the form ties.

The preset invention relates to an apparatus for coupling arranged-reinforcement bars that can more precisely supply wires and bind and cut reinforcement bars, using a linkage member that longitudinally moves with rotation of a main shaft, and can stably operate by stably moving a guider for guiding wires.

A pocket former may include a pocket former body, the pocket former body having an outer surface. The pocket former may further include a collapsible element, the collapsible element formed on the outer surface of the pocket former body. The collapsible element may extend radially outwardly from the pocket former body.

The invention relates to a system for connecting textile-reinforced structural modules along a connecting edge (76) having an edge groove (74) comprising yarn loops (4). According to the invention, the system comprises a wedge element (410) and two shell elements (420) having a keyway (422) and is provided for insertion into the two edge grooves (74) having overlapping yarn loops (4), wherein further the wedge element (410) is provided for partial extraction from the two oppositely arranged keyways (422) so that the shell elements (420) can be spread away from each other by wedge action and the yarn loops (4) can be pulled together. The invention further relates to an apparatus and a method for producing a textile reinforcement (10) comprising a yarn (2) arranged within a base frame (100) or for producing a textile-reinforced structural module (72) comprising the textile reinforcement (10) and a curable material, wherein a freely formable shaping device (200) is provided on which the structural module is formed. According to the invention, the textile reinforcement (10) can be formed between yarn holding devices (130, 180) arrangeable on bendable frame strips (110). The invention also relates to a concrete component comprising connected concrete structural modules and a printer description file, and a yarn deposition file.

The present invention provides construction methods for a concrete structure integrated with a waveguide tube, including: installing formwork that conforms to the shape and size of the concrete structure (C), referred to as a formwork installation step; installing a form tie system, including waveguide tube (40), between first formwork and second formwork, referred to as form tie installation step; pouring concrete after the first formwork, the second formwork, and the form tie system are completely installed, referred to as concrete pouring step; and removing the formwork and the form tie system, excluding the waveguide tube (40), after the concrete has initially hardened, referred to as a formwork removal step.

A composite rebar, which may include a reactive surface coating for improvement of the performance of buildings, freeways, and other concrete structures or other structures using rebar, where increasing the life and safety as well as improving the lifetime cost of the structure is important. Leveraging manufacturing opportunities of composite materials with an understanding of the mechanical properties of geometric shapes improves the system strength and reliability at minimal extra cost.

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. In some examples, a crimp for mechanically joining rebar for use in a support system for a physical structure includes a body with at least two recessed surfaces each configured for receiving a respective first and second piece of rebar; and a pair of spaced-apart arms at least partially enclosing an interior space of the body including the at least two recessed surfaces, a first tip and a second tip of the respective spaced-apart arms each defining a respective first and second opening to the interior space, in a first configuration.
