A compensating element for extending a modular set of stairs in the area of its top and/or bottom step, comprising a tube with a longitudinal axis and with a first end section and a second end section, a bracket for the reception of a step element, wherein the bracket is connected to the tube in the region of the second end section and is arranged at an angle with respect to the longitudinal axis of the tube, connecting means for connecting the tube to a vertical post and/or a vertical post element, wherein the connecting means are connected to the tube in the region of the first end section and in the region of the second end section are each connected to the tube via bracket-like holders, and wherein the bracket-like holders are arranged at an angle with respect to the longitudinal axis of the tube.

A connecting disc for connecting at least two scaffold elements comprising a basic body having a first main surface and a second main surface which is disposed opposite of the first main surface, and having an edge surface which runs round the basic body and connects the first main surface and the second main surface to one another; at least one longitudinal connecting opening which passes completely through the basic body; and at least two transverse connecting openings each of which passes completely through the basic body, each transverse connecting opening being delimited by a peripheral contour in a plan view of the first main surface, said peripheral contour having a receiving region and at least one blocking region which interrupts the receiving region and is disposed outside of the receiving region.

A scaffold node for connecting scaffold elements extending in different spatial directions, comprising a connecting sleeve which is provided as a coupling point for two scaffold components, in particular for two vertical posts or for a vertical post and a spindle nut post, and at least one coupling element which is used to connect the scaffold node to further scaffold components or scaffold elements. A scaffold portion comprising a scaffold node and further scaffold elements.

The invention is a jack base 10 of construction scaffolding which includes a base plate 20 that is fixed to the ground surface 1 and has a hole 21 formed through the center thereof; a screw shaft 30 whose lower end is engaged in the hinges 22,31 on opposite side of the periphery of the hole 21 on the base plate 20 and whose upper end is connected to the lower end of the vertical pipe 4; a support member 40 that is screwed to the screw shaft 30 and supports the vertical pipe 4 of the scaffolding 3; and a fixing bar 50 that penetrates the hole 21 in a swingable manner and is fixed by being embedded in a ground surface 1.

A scaffolding assembly is provided. The scaffolding assembly comprises a base assembly and a support assembly. The base assembly and support assembly are associated with a first common end support. The support assembly includes a second end support and a user supporting deck extending between the first common end support and the second end support, and the base assembly includes a third end support and a second deck extending between the first common end support and the third end support. The decks may comprise movably interconnected floor members. The support assembly may be disassembled and located in a storage area defined by the base assembly for ease of transport.

A connector for a scaffolding system includes end portions and a central portion. The central portion includes raised upper and side regions that protrude outward. Raised side regions of the central portion also includes an indent disposed distally from the raised upper region. The end portions are securable to a support beam of the scaffolding system, where the raised upper region is substantially coplanar with an upper wall of the support beam when the support beam is coupled to an end portion.
