A configurable form system for creating precast concrete panels is disclosed. The configurable form system can be used to create precast panels for both commercial tilt panels and highway noise barrier walls, among other applications. A plurality of form system sections are preferably fabricated from steel plate bent into a J-channel member. The configurable form system can be designed in sections that are quickly assembled. To suit a particular application, a section can be extended by sequentially attaching extension members to a primary member. A plurality or faces or shoring apparatuses can be coupled to the section to circumscribe or form an inner diameter of an enclosure formed by the sections. The shoring apparatuses can vary in height, allowing for fabrication of panels of variable thickness using the same forms or framework. The shoring apparatuses can be configured to removably engage ends of sections to facilitate the formation of enclosures using the sections.

A connection system includes a turnbuckle having a first set of threads and a second set of threads disposed on an inner surface of the turnbuckle. The turnbuckle is configured to couple two threaded components to one another via rotation of the turnbuckle in a first direction. In addition, the connection system includes a compression washer configured to compress as the turnbuckle rotates in the first direction. The compression washer is configured to apply a longitudinal force to the turnbuckle while the compression washer is compressed to increase resistance to rotation of the turnbuckle in a second direction, opposite the first direction.

A turnbuckle-style support strut with tunable stiffness, wherein the turnbuckle-style support strut uses opposing stacks comprised of one or more Belleville spring washers to provide the tunable stiffness to support a given application.

The present disclosure relates to a formwork anchor receptacle for arrangement on a bearing element of a formwork element, having a receptacle element, which has a receptacle opening for insertion of an anchor rod and a ball section for mounting on the mounting element of the formwork element, and having a retaining apparatus for retaining the receptacle element on the bearing element of the formwork element, wherein the retaining apparatus has a spacer element for contacting the bearing element of the formwork element, wherein the spacer element has an mounting opening for mounting on the receptacle element and a formwork device having such a formwork anchor receptacle.

A holder for holding an object on a formwork panel, in particular for holding a railing component on a ceiling formwork panel, wherein the holder is configured for being affixed to the formwork panel, and the formwork panel has two longitudinal edge supports and two transverse edge supports,

wherein the holder has a first arm that is configured for engaging with a longitudinal edge support of the formwork panel and a second arm that extends transverse to the first arm, forms an angle space together with the first arm, and is configured for engaging with the second arm,

wherein the first arm has a first projection for being introduced into an opening of the longitudinal edge support on its side facing the angle space, and the second arm has a second projection for being introduced into an opening of the transverse edge support on its side facing the angle space.

Various implementations described herein are directed to a bracket of a formwork system. In one implementation, the bracket includes: a first member having a first plurality of openings; and a second member having a second plurality of openings. The first member and the second member are configured to: be perpendicular to each other; and provide lateral adjustment via the first plurality of openings and/or the second plurality of openings.

A connection assembly for formwork elements includes a counterplate, a bolt, and a bolt block. The counterplate can include a plurality of surfaces having differing heights that selectively engage with a waler during engagement or disengagement of the bolt from the formwork element. The formwork element can include a J-shaped waler that allows for easy climbing and/or hanging of objects on a site. The connection assembly can include a bolt block that removably engages a formwork element.

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.

This disclosure relates to a formwork panel assembly to mold upwardly extending building features such as columns or walls, that extend between adjacent floor slabs. In one aspect, the formwork panel assembly comprises at least two surface forming elements, and at least one connecting element adapted for removable location between the two surface forming elements, where adjacent edges of the surface forming elements abut against the connecting element so that the resulting formwork assembly forms a single, continuous casting surface, and wherein in use, the or each connecting element is separately releasable from the formwork assembly once a concrete surface has been formed.
