A holder for holding an object on a formwork panel, in particular for holding a railing component on a ceiling formwork panel, wherein the holder is configured for being affixed to the formwork panel, and the formwork panel has two longitudinal edge supports and two transverse edge supports, wherein the holder has a first arm that is configured for engaging with a longitudinal edge support of the formwork panel and a second arm that extends transverse to the first arm, forms an angle space together with the first arm, and is configured for engaging with a transverse edge support, wherein the first arm has a first projection for being introduced into an opening of the longitudinal edge support on its side facing the angle space, and the second arm has a second projection for being introduced into an opening of the transverse edge support on its side facing the angle space.

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.

Disclosed herein is a method for erecting a shuttering framework. The method comprises the steps of a) mounting one end of a first support to the ground or other stationary object and mounting one end of a first brace to the ground or other stationary object, b) attaching the opposite end of the first brace to the opposite end of the first support or to a position between the two ends of the first support, c) repeating a) and b) for a second support and a second brace, and d) mounting a plurality of ties between the first and second supports. Also disclosed herein is a method of casting concrete.

A climbing support subsystem usable with a self-climbing system for multi-sided cores having three walls or an otherwise non-rectangular or non-square building core.

A structure construction apparatus according to one embodiment comprises: a frame unit provided on the ground on which a structure is to be constructed; a formwork unit which is mounted on the frame unit, and which maintains structural materials in a form to be constructed; and a compacting unit disposed to be adjacent to the formwork unit so as to compact the structural materials provided in the formwork unit, wherein the formwork unit and the compacting unit are moved by means of the frame unit so that the structure can be automatically constructed.

Various implementations described herein are directed to a modular ledger of an integrated construction system. In one implementation, the modular ledger includes a rail, having a first end and a second end. Each end of the rail is configured to receive a coupling component. The rail has a plurality of holes configured to couple to bracing components of the integrated construction system.

An independent self-climbing form system may be assembled at a work site to build, maintain, or repair vertical structures. The independent self-climbing form system may include a plurality of support towers. Additionally, at least two trusses may be connected to the plurality of support towers. The trusses may be spaced apart from each other. Further, one or more platforms may be formed within a perimeter delimited by the at least two trusses. The at least one or more platforms may be configured to extend or retract within the perimeter. Furthermore, screw jacks may be disposed at each connection point of the at least two trusses on the plurality of support towers. The screw jacks may be configured to vertically move the at least two trusses up and down the plurality of support towers.

A foldable brace assembly for supporting concrete formwork includes a ground brace member pivotably coupled with an end of a wall brace member, such that the wall brace member can pivot to be generally parallel or generally perpendicular relative to the ground brace. With the wall brace member perpendicular to the ground brace member in an erect position, a diagonal brace member detachably couples between an upper portion of the wall brace member and the other end of the ground brace member. The brace assembly may be locked in the erect position, such as by inserting a pin in aligned openings in the wall brace member and the ground brace member. When the brace assembly is not in use, the pin may be removed and the brace assembly can pivot to a folded position with the wall brace member can pivot to be generally parallel to the ground brace.

A holder for holding an object on a formwork panel, in particular for holding a railing component on a ceiling formwork panel, wherein the holder is configured for being affixed to the formwork panel, and the formwork panel has two longitudinal edge supports and two transverse edge supports,

wherein the holder has a first arm that is configured for engaging with a longitudinal edge support of the formwork panel and a second arm that extends transverse to the first arm, forms an angle space together with the first arm, and is configured for engaging with the second arm,

wherein the first arm has a first projection for being introduced into an opening of the longitudinal edge support on its side facing the angle space, and the second arm has a second projection for being introduced into an opening of the transverse edge support on its side facing the angle space.
