A support head mountable on a support post for supporting a beam in a formwork system is provided. The support head includes a top member for contacting and supporting the beam, a base member mountable on top of the support post, and a pin. Each of the top and base members has a tube with opposing pin holes. The tubes are configured to form vertically extending telescopic tubes, with the pin holes aligned along a horizontal axis. The pin is insertable into the pin holes, and has spaced apart depressions thereon. The pin is slidably moveable in the pin holes from a first position to a second position. In the first position, the depressions are offset from the pin holes. In the second position the depressions are aligned with the respective pin holes thus lowering the first tube and the top member in height.

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.

End fittings may be designed so that they connect to each other in more than two configurations. A first end fitting may be connected to an adjoining end fitting, removed, rotated ninety degrees and reconnected with the adjoining end fitting without jeopardizing stability of the position of each end fitting relative to the other. The first end fitting may be connected to the adjoining end fitting, removed, rotated an additional ninety degrees and reconnected with the adjoining end fitting without jeopardizing stability of the position of each end fitting relative to the other. The first end fitting may be connected to an adjoining end fitting, removed, rotated a yet further ninety degrees and reconnected with the adjoining end fitting without jeopardizing stability of the position of each end fitting relative to the other.

A clamp and universal wedge clamp system is provided. The system includes a rigid clamp that is formed to define first and second arms that extend from opposite ends of a central member. The first and second arms each comprise a finger that extends inwardly toward the finger extending inwardly from the opposite arm, and at least one of the first and second arms comprising a slot defined through the arm along a portion of a length of the arm. A wedge extends through the slot, wherein the clamp and the wedge are collectively configured to removably retain a beam upon either one of a substantially cylindrical shoring post, or a substantially rectangular shoring post.

The support 10 of the present invention resembles a conventional Acrow prop which may be used for temporarily supporting a load. In particular, the present invention is arranged to support a surface at a static position. For example, the surface may comprise a ceiling/beam/lintel within a structure wherein the usual permanent supports for the ceiling/beam/lintel are being replaced or deemed temporarily insufficient. However, the present invention can be used in numerous situations where a support 10 is required and for which the support 10 can be quickly and easily installed. The present invention provides (hydraulic) movement means to move the upper end relative to the lower end. In addition, the present invention provides retraction prevention means to prevent the upper end moving towards the lower end whilst supporting the load and prevents the inner core member 14 being forcibly retracted back into the outer sleeve member 12 due to the compressive force of the load. A hydraulic ram 22 has a maximum extension limit and the present invention uses an adjustable mounting/abutment mechanism which means that a relatively small hydraulic ram 22 can be installed in the outer sleeve member 12. This size of hydraulic ram 22 will then be suitable for all heights and the support is not limited to simply being moveable within a restricted range.

An adjustable strut that includes an outer housing configured to receive an extendable member, and an extending mechanism with a gear system configured to convert rotation motion of an input mechanism into linear translation of the extendable member.

Example aspects of an indicator for a compression post, a compression post for a building, and a method for using a compression post are disclosed. The indicator for a compression post can comprise a leg configured to engage a support plate of the compression post; and an indication portion supported by the leg and comprising; a first visual indicator configured to indicate that the compression post is in an uncompressed configuration; and a second visual indicator configured to indicate that the compression post is in a compressed configuration.

The present invention relates to a sensor device, system, and monitoring system for monitoring force and inclination of load supporting members, such as temporary support props. The sensor devices include a tubular member that interface with and slidably/detachably attached to the temporary support props, and sensors on the tubular member for measuring force, inclination and position of the temporary support props for construction and demolition work. The sensor device includes a controller for processing data from the sensors. The sensor system includes a wireless device that communicates with the sensor device. The sensor system further comprises positioning device, such that precise location or position of the sensor devices may be detected/calculated by the sensor system. The monitoring system includes a server that communicates one or more sensor systems to form a network.

Formwork support comprising an outer support part and a telescopic inner support part, wherein the inner support part comprises a twist-proof portion and the outer support part comprises a twist-proof region with a first inner contour, wherein during telescoping of the inner support part, the twist-proof region of the outer support part cooperates with the twist-proof portion of the inner support part in such a manner that a twisting of the inner support part about its longitudinal axis with respect to the outer support part is blocked, wherein the outer support part comprises a guide region with a second inner contour which differs from the first inner contour for guiding the inner support part.
