The invention relates to a support head (20, 20.sup.(l)) for attachment to a formwork support (18a-18l) for creating the formwork for a floor (44) using a large number of floor formwork elements (14a-14u) which each have a form surface (22). The support head (20, 20.sup.(l)) has two support portions (32, 34) suitable for supporting at least one pair of adjacent floor formwork elements (14j, 14k) of the large number of floor formwork elements (14a-14u). The support head (20, 20.sup.(l)) has an adjustment device (46) for moving a first support portion (32) into an arrangement in which the floor formwork element (14j) which can be mounted on the first support portion (32) can be mounted thereon on at least one subjacent mounting point (P.sub.3) which is at a lower mounting height (h.sub.2) than a formwork mounting height (h.sub.1). The mounting point (P.sub.2) of the second support portion (34) remains at the formwork mounting height (h.sub.1).

Four types of telescoping modules are disclosed wherein the first type has a pair of opposed female ends, the second type has a pair of opposed female ends, and the third type has a female end and an opposed male end. The fourth type has two opposed male ends between which a positionable threaded rod and retaining components stably extend the length between the male ends of the telescoping module. Alternatively, the fourth type of telescoping module may have a female end and a male end. Each of the male ends of the second, third, and fourth types of telescoping modular components comprises a cylindrical body with one or more linear set(s) of two or more spaced-apart prongs on the circumferential surface of the cylindrical body. Each of the female ends has a cylindrical receptacle with one or more linear channels and/or prong-retaining slots for receiving therein the cylindrical body.

A support post for releasable fixation between a first and a second floor, comprising: a first and a second elongate member telescopically connected to one another, first floor and second floor engaging members positioned at the ends of the first and second elongate members, a displacement unit for displacing the first floor engaging member, a spring biasing the first floor engaging member in a direction away from the first elongate member, the first floor engaging member being moveable in towards the upper end of the first elongate member against the force of the spring, a first inspection window in the first elongate member, a second inspection window adjacent to the first inspection window, an indicator having a first marking arranged at the second inspection window in a relaxed state of the spring, and having a second marking arranged at the second inspection window in a loaded state of the spring.

The present disclosure relates to a prop (10) comprising a first tube (14) and a second tube (16). The first tube (14) is telescopically connected to the second tube (16) for axially displacing the second tube (16) between a retracted position and an extended position. The first and second tubes (14, 16) each comprise a loading end for receiving an axial load from opposing load surfaces (62, 64) in the extended position. The first tube (14) and the second tube (16) are made from a plastics material.

A collapsible barrier including a substantially rectangular sheet having a first telescopic post and a second telescopic post pivotably connected with hinges. Feet extend from the bottom of the first telescopic post and the second telescopic post. A first-bracing member and a second-bracing member respectively reinforce the first telescopic post and the second telescopic post in a perpendicularly oriented position with respect to each other. A metallic webbing integrated with the substantially rectangular sheet to provide suitable strength and load bearing capabilities. The telescopic posts are configured to extend and retract to a height of a ceiling with a twisting motion. When the feet are aligned parallel with the substantially rectangular sheet the lip of the substantially rectangular sheet allows multiple collapsible barriers to be stacked. The collapsible barrier is useful for providing a portable barrier without the need for drilling into a floor or ground surface.

A coupler comprises a first channel having a first axis of extension in a first horizontal direction and a second channel having a second axis of extension in the first horizontal direction. The second axis of extension is parallel to and spaced apart from the first axis of extension in a second horizontal direction. The second axis of extension has a pitch angle relative to the first axis of extension in a vertical direction, the pitch angle being less than 180 degrees. The first and second channels each include head-mounting features, the head-mounting features constructed and arranged to retain an elongated head to the coupler while permitting movement of the elongated head relative to the coupler in the first horizontal direction.
