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.

An equalizing beam for receiving formwork elements, in particular formwork panels, having an outer beam having a support surface facing upwards when applied and a base surface facing downwards when applied, and at least one inner beam having an additional support surface facing upwards when applied and an additional base surface facing downwards when applied. The equalizing beam further includes at least one immobilizing element. The outer beam has a recess running in its longitudinal direction for receiving the inner beam and the inner beam is movably mounted in the recess of the outer beam. The immobilizing element is provided to secure the position of the inner beam relative to the outer beam. A ceiling formwork system including at least one equalizing beam and at least two supports which are arranged essentially at a right angle to the equalizing beam.

The invention relates to a system and method for determining and visualizing force flows in a bar supporting structure (1), which is preferably in the form of scaffolding, comprising a plurality of ladder or strut elements (5a-5c) which extend vertically and are set up in a disputed manner relative to one another and which are detachably connected via scaffolding couplings (7) to strut elements (6a-6d) extending diagonally and/or horizontally transversely thereto, wherein at least a load-critical part of the support elements (5a-5c) and/or strut elements (6a-6d) and/or scaffold couplings (7) of the bar structure (1) are provided with load sensors (8a-8c) for detecting static operating load values, the measured values of which are analysed in real time by a downstream analysis unit (9) for evaluating current load situations.

A ceiling formwork system having a formwork panel which may be placed on at least one vertical support via a mounting head. The mounting head has an anchoring cross-member which in the mounted state on the vertical support is oriented transverse thereto, the length of the anchoring cross-member corresponding to at least one side length of the ceiling formwork panel to be supported, whereby the anchoring cross-member is respectively affixable at its ends to lateral edges of the ceiling formwork panel.

A perimeter protection system for protecting operators against lateral falling when installing formwork panels in a horizontal formwork system. According to one embodiment the perimeter protection system includes a perimeter protection structure configured for being fixed, in a working position, to the horizontal formwork system, and at least one auxiliary device configured for being fixed to the horizontal formwork system and for fixing the perimeter protection structure to the horizontal formwork system. The auxiliary device includes guiding means collaborating with a guide of the perimeter protection structure for positioning the perimeter protection structure in an initial assembly position. In the initial assembly position the structure is configured to be raised up to an intermediate position where it is permitted to swing until it is positioned in the working position.

A formwork element of a ceiling formwork. The formwork element has a non-fully circumferentially closed, in particular U-shaped, frame onto which a formwork skin can be or is arranged. The frame preferably has at least a first leg, a second leg and a base strut in between. The base strut is preferably oriented at a right angle ±5° relative to the two legs. The legs are preferably each provided at their end regions opposite to the base strut with a fastening projection and/or a fastening recess. The formwork element can be suspended by a worker from below into a pillar head and is upwardly pivotable. It makes it possible to build around an obstacle in a simple manner while maintaining a grid-like imprint structure in the concrete surface to be created with the ceiling formwork.

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.

An anchoring head for formwork struts is intended for the implementation of inclined floor slabs, and includes a support, an erect region coupled to a strut to be mounted, wherein there are two separate positioning shafts transversely arranged with respect to the erect region, that are adjustable in height by means of a height adjusting system, the positioning shafts being configured to support a respective beam in a fixed way by means of releasable locking means. The support includes a visual indicating means for indicating the angular position of each beam to be supported, the indicating means being associated with the positioning shaft of the beam to be supported by means of a cam arrangement, the cam arrangement being provided with a cam member coupled to the positioning shaft, such that the position of the cam member is directly related to the height at which the positioning shaft is located.

A main beam for a formwork grid construction component system is disclosed. Typical main beams work with secondary joists (sometimes referred to as secondary beams to support a decking surface for pouring of concrete or cement. By strengthening the main beam using an altered profile while maintaining interoperable external dimensions, the span distance of each joist may be increased. By forming the main beam with the disclosed profile, joists can be made longer (e.g., have an eight foot connected span to increase grid size) and maintain appropriate strength (or increased weight tolerance). Formwork grid systems are used in construction of buildings and other structures. Interoperability with existing components is maintained by the disclosed main beam adhering to the same external functional form factor. The external form factor being the same allows main beams constructed in accordance with this disclosure to properly function with existing formwork grid construction components.

A prop head assembly is configured to be fixedly connected to a vertically-extending construction column, and also configured to support a horizontal construction beam assembly once the prop head assembly is fixedly connected to the vertically-extending construction column. The prop head assembly includes a first beam-locating feature and a second beam-locating feature. The first beam-locating feature is configured to selectively receive, at least in part, a beam-reference portion. The second beam-locating feature is also configured to receive the beam-reference portion once the beam-reference portion is inadvertently displaced away from the first beam-locating feature and from the vertically-extending construction column and toward the second beam-locating feature.
