A configurable steel form system for creating precast concrete panels is disclosed. The configurable steel 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 steel form system sections are preferably fabricated from steel plate bent into a J-channel member. The configurable steel 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 quick-release mechanism can be implemented for ease and speed of connection. Each section can have the panel depth and contour fabricated into the steel form profile. Anchoring holes and corner miters can also be cut into the form's framework.

A holder for supporting a threaded rod for being embedded in concrete, comprising a central portion including a first opening for receiving an end portion of a threaded rod; a ring portion; arm portions connecting the central portion to the ring portion, the arm portions including respective base portions; leg portions attached to the ring portion; and the central portion extending above and below the base portions.

A filler panel assembly for use with a concrete forming system comprising one or more filler bar assemblies having a panel element disposed therebetween. Each of the filler bar assemblies is secured to the panel element. Each filler bar assembly includes a filler bar having a flange portion and a longitudinally extending and one or more bolt plate assemblies. Each bolt assembly includes a bolt plate having a main body that has an aperture formed therein and a pair of opposed flanges that are formed in a front surface of the main body and which extend outwardly from a rear surface thereof, a nut element, and a shoulder bolt element.

The present invention corresponds to a formwork mechanism for casting and molding concrete, comprising a coffer having a sheet and four plates arranged around the sheet perimeter. Each plate has holes arranged on its front face. Also, the formwork mechanism includes a structural element, connected to one of the plates by fixing means. On the other hand, the structural element has lateral perforations that are aligned with the holes of one of the coffer plates. Fixing means pass through the holes and side holes. The structural element may be a beam, a three or four-beam T, and combinations thereof. On the other hand, using several coffers interconnected with structural elements, formworks are constructed for casting flat reticular slabs; and also for curved reticular slabs with greater slab thickness near the beams supporting the slabs in comparison to the span of the slabs.

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.

Various implementations described herein are directed to a load bearing ledger fitting, a modular header beam, a perimeter safety deck, a multi-purpose bearing plate, and a mega-shore bearing plate of an integrated construction system.

A turnbuckle for tensioning frame formwork elements, the turnbuckle comprising a first clamping apparatus which has a crosspiece and a first clamping jaw. The crosspiece has a guide portion comprising a row of track teeth which are arranged behind one another and extend in parallel with one another. The turnbuckle also has a second clamping apparatus which has a second clamping jaw. The second clamping apparatus can be shifted in a tensioning direction along the longitudinal axis of the crosspiece towards the first clamping jaw. The track teeth extend in each case in an arc from a first longitudinal edge of the crosspiece towards a second longitudinal edge of the crosspiece. The second clamping apparatus has at least one support tooth which extends in an arc and can be rotated about a rotational shaft.
