A tooling for manufacturing a wall with two concrete walls, between which at least one insulation panel is trapped includes at least one system for positioning the insulation panel composed, on one hand of a dagger having a rod provided with a bearing stop and, on the other hand, of a lock provided with a counter-stop. The lock has at least two notches for receiving a first reinforcement, arranged locally on the circumference of the positioning system, extending set back from a first end of the rod, delimited on either side by retaining stops spaced apart so as to maintain in position the first reinforcement, and defines a housing with a profile converging in the opposite direction to their opening, and arranged according to the length of the positioning system to be able to adjust the position of the first reinforcement according to the length of the positioning system.

A module for the production of concrete parts has a row of displacement bodies that are adjacently arranged in a horizontal longitudinal direction (L) and that are clamped captively to a grid structure made of at least two individual grids running in the longitudinal direction (L). Surfaces of the grids are oriented in a transverse or inclined manner in relation to the horizontal. Each of the grids has at least a first and a second longitudinal bar arranged at a distance in parallel to one another and running in the longitudinal direction (L) and a plurality of transverse bars being arranged at a distance from one another and oriented in a transverse or inclined manner in relation to the horizontal. The transverse bars are respectively connected with the longitudinal bars. One of the displacement bodies for each grid has a first and a second retaining device.

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 invention relates to a concrete shaping insert, which is formed to be arranged in a formwork mold before a concreting process, comprising a first and second fixing element, between which at least one displacement body is arranged. The concrete shaping insert is characterized in that, the displacement body has an interstitial tube and that the first and second fixing element are connected to one another with at least one connecting component, which proceed through the interstitial tube.

A number of modular preformed skeletal steel panels are mounted side by side in a row on a building structure to form a composite panel assembly on the building structure. Each modular preformed skeletal steel panel comprises two mesh layers, namely a bottom mesh layer and a top mesh layer supported spaced-apart in parallel planes by intermediate spacers extending between the layers. The bottom layer has a plurality of spaced-apart outwardly projecting splice bars for interengagement with an adjacent preformed skeletal steel panel in the panel assembly thus facilitating interengagement of the modular preformed skeletal steel panels in the composite panel assembly. Each spacer comprises a cross member engaged with the top layer and having outwardly extending legs at opposite ends of the cross member. A lower end of each leg terminates in a foot which engages with the bottom layer. The cross member, legs and feet are all mutually perpendicular.

A system for use with a post-tensioning concrete anchor may comprise a connector anchor including a bore therethrough, the bore including a first frustoconical portion, the connector anchor adapted to bear on the post-tensioning concrete anchor, and a coupler. The coupler may comprise a coupler body including a bore therethrough, the bore including a second frustoconical portion that is oriented oppositely to the first frustoconical portion, and a connector having a bore therethrough and configured to receive the coupler body therein, the connector adapted to mechanically engage the connector anchor such that a tensioning force can be transmitted from the coupler body to the connector anchor via the connector. A method of using the system may allow a second concrete section to be poured adjacent to a first concrete section before the first concrete section has been stressed.

Connector for connecting rebar intersections of a foldable FRP rebar cage includes two channels for receiving the intersecting FRP rebar. One channel has a spherical member and the other has arms shaped to hold the spherical member, to allow the connected rebar to rotate in the X, Y and Z axes.
