A guardrail for a scaffold, which has at least at one end a coupling section for coupling with a coupling element of a vertical post or vertical frame of the scaffold, wherein the coupling section is flat and is penetrated by an elongate opening which extends parallel to a longitudinal axis of the railing member and which has a constant width as far as an extension at the end.

A scaffold comprising a guardrail, a method for erecting a scaffold and a use of a guardrail.

The invention relates to a temporary scaffolding rest which temporarily supports a standby scaffolding component upon a scaffolding upright in a first temporary disconnected position which is laterally offset from the scaffolding upright for subsequent installation of said standby scaffolding component to a portion of said upright in a second installed position which is laterally inset from the first temporary disconnected position. The temporary scaffolding rest includes a temporary connector for temporarily connecting the temporary scaffolding rest to said portion of said scaffolding upright, and an elongated rest which extends laterally from the temporary connector in order to temporarily support a portion of said standby scaffolding adjacent said portion of said scaffolding upright in said first temporary disconnected laterally offset position ready for subsequent installation to said portion of said scaffolding upright in said second installed position. A method of erecting a row of scaffolding which is higher than the row of scaffolding upon which an installer is positioned is also provided.

A modular guard rail for construction scaffolding includes first and second vertical support members and horizontal rails defining a guard rail frame. Support brackets are provided for engaging respective vertical posts of the construction scaffolding and a horizontal supporting strut of the construction scaffolding.

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.

Preceding guardrail for a scaffolding system for buildup of a scaffold bay. The guardrail assembly comprises a guardrail, a base part, a mounting system for mounting of the base part to a part of the scaffold bay, at least a first post and a second post, and a lifting arm. The guardrail extends along a longitudinal axis. The base part extends substantially parallel to the longitudinal axis of the guardrail. The first and second post are each pivotably connected to the guardrail by a first pivoting point and pivotably connected to the base part by a second pivoting point, whereby the guardrail, the base part, the first, and the second post together form a parallelogram link system. The lifting arm is fixedly connected with the first post and extends in line with the first post from the second pivoting point away from the first pivoting point.

Preceding guardrail holder for a scaffolding system, configured for cooperation with guardrails provided with a fastening hook at a longitudinal end. The preceding guardrail holder includes a first and a second cross connection element extending perpendicular to a mounting plate and a retaining plate, which cross connection elements are mutually spaced apart and together bound a fastening hook receiving space for receiving in the fastening hook receiving space the fastening hook of a first guardrail. The distance between the first and the second cross connection element is such that, if the fastening hook is received in the fastening hook receiving space and the first guardrail is not supported otherwise, a recess on a radial inner side of the fastening hook rests on the first cross connection element, and a radial outer side of the fastening hook abuts against the second cross connection element, the first guardrail thereby being wholly supported by the single preceding guardrail holder.

A scaffolding element having a scaffolding pole, at least one fastening element being disposed or formed on the scaffolding pole. The fastening element preferably has a fastening element body. The fastening element body can be L-shaped. Preferably, the free end of the fastening element body points straight upwards when the scaffolding element is in the mounted state. A projection is disposed or formed below the free end on the fastening element body, in particular in a section parallel to the longitudinal axis of the scaffolding pole. The projection can be part of a U-shaped bead.

The invention relates to a scaffolding element having a scaffolding pole (12i), at least one fastening element being disposed or formed on the scaffolding pole (12i). The fastening element preferably has a fastening element body. The fastening element body can be L-shaped. Preferably, the free end of the fastening element body points straight upwards when the scaffolding element (22) is in the mounted state. A projection is disposed or formed below the free end on the fastening element body, in particular in a section parallel to the longitudinal axis of the scaffolding pole (12i). The projection can be part of a U-shaped bead.

An individual scaffolding post made of metal for facade scaffolding or of facade scaffolding has secured thereon a single rosette for detachably securing at least one horizontal bar. A railing securing device is secured above the rosette, on which a railing strut is detachably supported. The railing securing device includes a rigid bracket permanently secured to the post, which together with an outer surface of the post surrounds and engages around a vertical receiving slit through-opening. A railing rod end of the railing strut has a first recess on the underside, which is open to side surfaces of the railing rod end extending away from one another and is open downwards. The railing rod end has a mounting hook limiting a first recess and partially surrounding same with its free hook end extending to the rear. The free hook end engages behind the bracket contact part of the bracket.

During erection of a scaffolding use is made of a coupling device with a base part (20) which is connected temporarily, but reliably, to a distal section of a ledger element (10) and to a coupling part (30) extending from the base part (20). The coupling part (30) comprises at the outer end a hook (35) which is placed round a subsequent upright (5) of the scaffolding in order to thus make a secondary connection thereto, while a primary connection (9,11) between the ledger (10) and the upright (5) is only completed later.
