A transmitter for predicting stress on a formwork element during and/or after pouring a building material, in particular concrete, into a space enclosed by a formwork including the formwork element, the formwork element comprising a form face and a support structure which is attached to the form face and supporting the form face, wherein the form face is separated from or integrated into the support structure, the system comprising data acquisition means, at least one sensor unit, a control unit and a transmission unit.

In a first aspect there is disclosed a support structure assembly (10). The support structure assembly includes a first wall panel (12) operatively associated with an opposing, spaced apart second wall panel. The first wall panel (12) including a channel (14) having two spaced apart channel walls (16) connected via a transverse channel base (18). The channel (14) encloses a resilient body (20).

Various implementations described herein are directed to a formwork system. In one implementation, the formwork system includes aluminum extrusions and aluminum castings. The aluminum castings and the aluminum extrusions can be assembled by being pressed and riveted together.

The described Concrete Form Brace With Multi-Depth Rebar Positioning is comprised of opposing attachment members, which secure the brace to the concrete form elements. The attachment members have a first top end, and a second bottom end. The corresponding bottom ends of the attachment members are connected by a spanning element, which spans the width of the concrete form. The attachment members and spanning element are further connected by a plurality of reinforcing struts. Rebar attachment means at multiple vertical depths within the concrete form are integrated or connected to the reinforcing struts to provide rebar securement means at multiple depths within the poured concrete. The preferred embodiment also features vertical spacing between horizontally placed rebar to accommodate “L” shaped vertical rebar placement for applications where vertical rebar is specified.

Concrete form assemblies having insulating foam panels are created using locking members embedded within the insulating foam panels and ties each having a pair of side rails for coupling two insulating foam panels together at a predetermined distance apart, the locking members and side rails being adapted so that either side rail can be coupled to either locking member and either of the ends of the rails and locking members can be toward the top or bottom of the assembly when the rails are coupled to the locking members.

A striking tool having a base element and a striking element configured to engage with a formwork panel. The striking tool has a plurality of struts, wherein the base element, the striking element, and the plurality of struts define a parallelogram configuration and an actuation mechanism configured to cause relative motion between the base element and the striking element.
