A modular building formwork apparatus includes a formwork wall and at least one interlocking device. The formwork wall includes a wall plate and a frame disposed on the wall plate. The frame has an aligning hole and a locking hole. The interlocking device includes a housing unit, a rotation transferring unit, a transmitting unit and a locking member. The rotation transferring unit has an input shaft and an output shaft. The transmitting unit is movable relative to and rotatable about the output shaft. The locking member has a head portion, a positioning portion and a threaded portion. The locking member is insertable into the aligning hole to permit the threaded portion to threadedly engage in the locking hole.

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.

A locking member is suitable for assembling two building formworks each including a positioning hole and a locking hole, and includes a driven portion, a shoulder formed on one end of the driven portion, a first tapered section connected to the shoulder and configured to be inserted into the positioning hole of one building formwork, and a second tapered section connected to the first tapered section and configured to be inserted into the locking hole of the other building formwork, and a threaded portion connected to the second tapered section and configured to threadedly engage with the locking hole.

The invention comprises a product. The product comprises a first removable concrete form having a concrete forming face and a first insulating panel insert having a first primary surface and an opposite second primary surface, wherein the second primary surface of the first insulating panel insert contacts the concrete forming face of the first removable concrete form. The product also comprises an elongate anchor member having an enlarged portion and an elongate portion, the elongate portion having a first end and an opposite second end, wherein the enlarged portion is disposed adjacent the first end and contacts the second primary surface of the first insulating panel insert and wherein the elongate portion extends through the first insulating panel insert and extends outwardly from the first primary surface of the first insulating panel insert. A method of using a removable insulated concrete form system is also disclosed.

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.

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.

The invention relates to a functional panel for receiving surface loads comprising a plurality of veneer layers that are arranged one on top of another and are connected together in a materially bonded manner, wherein a part of these veneer layers has an A-fibre direction, and another part of these veneer layers has a B-fibre direction oriented at more or less 90° to the A-fibre direction. The functional panel has a central plane defined substantially in the middle of the functional panel in the in the thickness direction. The cumulative thickness of the veneer layers with the A-fibre direction differs from the cumulative thickness of the veneer layers with the B-fibre direction on a first side of the central plane, and the cumulative thickness of the veneer layers with the A-fibre direction differs from the cumulative thickness of the veneer layers with the B-fibre direction on the second side located on the opposite from the first side of the central plane. As a result, the functional panel has an asymmetric structure in its thickness direction. The invention also relates to the use of a functional panel as a formwork shell for the formwork of a building part, and a method for producing the formwork of a building part with at least one functional panel.

The invention relates to a frame formwork element (1) with a frame (2) and a formwork shell (3) which can be attached to the frame (2). The frame (2) has at least two frame longitudinal parts (4) and at least two frame transverse parts (5). At least one transverse bracing (6) is fixed between the frame longitudinal parts (4), said transverse bracing having two transverse braces (7) which run parallel to each other in a mutually spaced manner and between which a through-gap (8) is formed for passing through anchor rods (9). At least one guide device (10) for forming an anchor point can be inserted into the through-gap (8). The guide device (10) has an anchor hole (11) for passing through one of the anchor rods (9) and a securing region (12) for securing the guide device (10) to the transverse bracing (6). In order to pass through the anchor rod (9), the guide device (10) has a conical guide part (13) which is flush with the anchor hole (11).

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.
