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.

Disclosed is a prop head for connecting a formwork prop to an elevated concrete slab formwork waler table or the like; said waler table having a plurality of support beams having a cavity or gap space adapted to receive an upper part of said prop head, said table being adapted to receive a bolt across said gap or cavity; wherein said prop head has: a central plate having a front end, a rear end and two sides, said sides having downwardly projecting lower L-shape angle brackets therefrom, said brackets being adapted to receive the top of said prop in a horizontally sliding manner from said front end; a downwardly projecting stop wall from the rear end of said central plate, adapted to abut the upper part of said prop; an upper turret, rising from said lower plate, adapted to fit in said cavity or gap space; and having one or more laterally located slots or holes adapted to correspond with the position of complementary holes or slots in said support beams; and a hole or slot in said central plate adjacent said front end and adapted to receive a locking pin, bolt or wedge thereby to prevent said prop being removed from said brackets. Also disclosed is a method of first securely connecting the prop to a support beam of a waler table and subsequently sliding the T-shaped end of a prop into connection with the prop head and then securing with a locking member.

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.
