An apparatus for producing a metal grid reinforcement from metal profiles including longitudinal profiles and a winding profile, the apparatus having a welding unit for welding a longitudinal profile, and a winding profile guide guiding the winding profile, which can be fed from a provision location of the winding profile to the winding profile guide, to the welding unit. The winding profile guide has a contact side and a positioning side that are movable relative to one another, with the contact and positioning sides being matched such that a winding profile present between the contact and positioning sides is forced into a centered position when the positioning and contact sides are moved towards one another. The positioning side has a recess which is matched to the winding profile and into which a longitudinal portion of a centered winding profile engages.

A wire shaping tool and method of using the tool to reshape wire, including the discrete sections of wire in a wire mesh panel, is provided. The tool includes a pair of levers joined at a fulcrum positioned closer to one end of the levers, a pair of jaws on one side of the fulcrum, and a pair of handles on the other side. The first jaw can include an elongate body with a concave surface having a pair of opposing lateral edges. The second jaw can include a complementary convex surface configured to converge toward contacting the concave surface of the first jaw. The concave and complementary convex surfaces can transform the shape of a wire positioned between the jaws when they are actuated. The second jaw can include a third shaping component that allows for the simultaneous reshaping of two adjacent wire sections in a wire mesh panel.

The present disclosure relates to a jig for manufacturing a reinforcement cage, which comprises a base member, a plurality of rollers disposed on the base member and spaced at intervals, a trolley which is movable on the base member; a driving device for driving the trolley; and a member for positioning the main reinforcement disposed at the first end of the base member.

A device and method for making a wire basket, the device having a spinning fixture with a top plate with an outer periphery, arms attached at a top end at the periphery of the top plate and projecting downwardly, such that bottom ends of the arms collectively form a circular arrangement having a diameter greater than the diameter of the top plate, a means for guiding wire onto the spinning fixture such that the wire is wound onto the spinning fixture in a preselected pattern, and contacts to maintain the wire onto the spinning fixture in preselected locations, and the method including providing an apparatus for delivery of wire through a wire feed and for translating the wire feed lineally along a traverse, providing a spinning fixture for winding wire thereon, and winding a preselected pattern of wire onto the spinning fixture by translating the wire feed along the transverse.

Disclosed is a pressure vessel for storing and keeping fluid and a three-dimensional shell structure used therefor. The pressure vessel has a shell structure in which an inner part is divided and partitioned into two sub volumes which are twisted with each other, by the interface and sub volumes are continuous, as a main body of the pressure vessel, and two sub volumes are independently utilized as a storage space of a high pressure vessel or a space for receiving or moving a heat exchange medium.

There is proposed a reinforced concrete structure comprising a reinforcement assembly embedded therein, the reinforcement assembly including first and second lengths of chain, wherein the first and second lengths of chain being pretensionable prior to forming the concrete structure. The reinforcement assembly includes pretensionable member/s and/or resiliently deformable member/s intermediate of at least one tetherable end of the lengths of chain and a mounting block or link member.

A manufacturing assembly and method produce a wire mesh including a plurality of longitudinal members and a monolithic transverse member secured to the plurality of longitudinal members. The monolithic transverse member includes a plurality of transverse portions that define a first cross-sectional shape, and further includes a plurality of longitudinal portions that define a second cross-sectional shape different than the first cross-sectional shape.
