A joist for a formwork grid construction component system is disclosed. Typical joists (sometimes referred to as secondary beams) span a distance of approximately six feet (when fully connected). By strengthening the joist using an altered profile while maintaining interoperable external dimensions, the span distance may be increased. That is, by forming the joists with the disclosed profile, joists can be made longer (e.g., have an eight foot connected span) and maintain appropriate strength or even have an increased weight tolerance. Formwork grid systems are used in construction of buildings and other structures. Interoperability with existing components is maintained by the disclosed joist profile adhering to the same external functional form factor as existing joists. The external form factor being the same allows joists constructed in accordance with this disclosure to properly function with existing formwork grid construction components.

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.

The invention relates to a frame formwork element (100) for a frame formwork system (300) for producing a wall section in concrete construction, comprising: a plurality of, in particular four, edge profiles (101) which form a frame (102) having a frame inner side (103) and a frame outer side (104), wherein at least one edge profile (101) is a hollow profile and in the cross-section has a profile section on the frame inner side with a groove-forming fastening corrugation (107) and a profile section on the frame outer side with a groove-forming reinforcing corrugation (105), wherein in the cross-section of the edge profile (101) the fastening corrugation (107) and the reinforcing corrugation (105) lie opposite one another and have the same shape. The invention further relates to a frame formwork system (300) having such a frame formwork element (100) and a batten (200). Moreover, use of a batten (200) in a framed formwork system (300) is proposed.

A connecting system is for dismountably connecting two intersecting formwork beams. The system includes a resilient single-component structure having two intermediate arms joining together respective regions for pressing the two intersecting formwork beams together at support regions. The resilient single-component structure is configured to slide longitudinally over one of the two intersecting formwork beams. Pressure or impact on the resilient single-component structure produces elastic deformation of the resilient single-component structure so as to clamp or hold the two intersecting formwork beams and press them together. The two intermediate arms extend at their upper ends into respective extensions for pressing on support regions of one of the beams to be connected, while at the other end they extend into a U- or V-shaped bridge for pressing on the support region of the opposite beam to be joined. Each of the intermediate arms has double elbows joined to respective straight-parallel extensions.
