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.

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.

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.

A formwork system for a wall element, comprising at least one formwork panel, at least one connection component, and at least one frame section, wherein the connection component comprises at least one frame interface, which is designed to be releasably connected to a frame section, and at least one formwork interface, which is designed to be releasably connected to the formwork panel. The at least one connection component is connected here with its frame interface to the frame section, and the connection component is connected with its formwork interface to the at least one formwork panel. The connection between the connection component and the formwork panel and/or the connection between the connection component and the frame section is designed to be releasable when the system is constructed, and the frame section can be separated from the formwork panel.

A formwork system for a wall element, comprising at least one formwork panel, at least one connection component, and at least one frame section, wherein the connection component comprises at least one frame interface, which is designed to be releasably connected to a frame section, and at least one formwork interface, which is designed to be releasably connected to the formwork panel. The at least one connection component is connected here with its frame interface to the frame section, and the connection component is connected with its formwork interface to the at least one formwork panel. When the system is constructed, the frame section supports and positions the formwork panel, and the system can be used in a free-standing manner. A method for producing a wall element using such a system.
