A frame (100) of a formwork panel (200) is disclosed. The frame (100) includes at least one stiffener profile (204) formed between two opposite edges (214) of the frame (100) and having a slanted profile. The at least one stiffener profile (204) includes a first edge (216-1) adjacent to a flat portion (202) of the formwork panel (200), and a second edge (216-2) distal from the first edge (216-1). A surface (218) of the at least one stiffener profile (204) is sloping outwards from the first edge (216-1) towards the second edge (216-2) to form the slanted profile.

A compensation waler assembly (400) for connecting and aligning a pair of formwork panels (200) with each other is disclosed. The compensation waler assembly (400) includes a first bar (702-1), a second bar (702-2) disposed above the first bar (702-1), and a pair of hook sub-assemblies (704) disposed between the first bar (702-1) and the second bar (702-2). Each hook sub-assembly (704) is adapted to be engaged with one of the pair of formwork panels (200). Each hook sub-assembly (704) includes a hook-shaped portion (902) formed at one end of the hook sub-assembly (704) and adapted to be removably engaged with a slot formed in the respective formwork panel (200). The hook sub-assembly (704) further includes a distal portion (904) formed at the opposite end of the hook sub-assembly (704) and comprising a slot (706), and a locking component (708) adapted to be accommodated in the slot (706) to secure the hook sub-assembly (704) on the respective formwork panel (200).

Concrete form assemblies having insulating foam panels are created using locking members embedded within the insulating foam panels and ties each having a pair of side rails for coupling two insulating foam panels together at a predetermined distance apart, the locking members and side rails being adapted so that either side rail can be coupled to either locking member and either of the ends of the rails and locking members can be toward the top or bottom of the assembly when the rails are coupled to the locking members.

A concrete form apparatus and system for connecting opposing form sections at a desired distance from each other defining a space to receive poured concrete, the apparatus preventing the form section separation, the apparatus including a locking pin, form connector rotatably and releasably affixed to a form, and retainer affixed to arm defining a channel therein sized to be engaged within the slot whereby the locking pin is placed through corresponding holes in adjacent forms and engages a first form, extends through the relative distance between the forms, exits through a hole in the second form, and the channel of the retainer attached to the second form engages the locking slot on the locking pin maintaining a fixed distance between the forms and preventing form separation when pouring concrete. A system using the foregoing and also including clamps for affixing adjoining forms to one another is also claimed.

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.

Disclosed herein is a concrete formwork (1) for use in shuttering formwork. The formwork (1) comprises a base (2) and a plurality of clamping brackets (7). The clamping brackets (7) further comprise clamping members (10) engageable with the clamping brackets (7) to define a clamping portion aligned with openings (8) on the base (2). The base (2) is pivotally connected to a shuttering contact member (3) which is supported by two braces (4a, 4b). Also disclosed herein is a method of constructing a formwork (1).

A drophead nut for use with formwork building components is disclosed. The disclosed drophead nut maintains standard outward dimensions to allow interoperability with existing systems. The hitting surface of the drophead nut is typically used to align a gap in the nut with a retention pin and thus allow the nut to drop. This in turn allows a mid-plate to fall releasing pressure on a beam (joist and/or main) to allow that beam to be removed. The impact surface of the disclosed drophead nut has been enlarged, reinforced, and possibly repositioned to increase leverage. The resulting drophead nut may allow for reduction in number of impacts on an impact surface to provide alignment of the gap and retention pin, and thus activate compression of the drophead nut.
