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.

An interlocking device is adapted to lock two modular building formworks. Each formwork includes a wall plate and a frame. Each frame has aligning and locking holes. The interlocking device includes a housing unit secured to the frame, a rotation transferring unit having intersecting input and output shafts, a transmitting unit movably coupled with the output shaft, and a locking member having a head portion, a positioning portion and a threaded portion. The locking member is insertable into the aligning hole of one frame to have the head portion abutting against the frame, and the threaded portion is matingly engageable in the locking hole of the other frame so as to lock the two formworks.

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.
