An enclosure system is provided for weatherproofing the work area on a standard scaffold structure adjacent a vertical wall surface and attachment thereto, comprising a framework consisting of a plurality of spaced apart base bars joined to an equal plurality of extension bars, and an overlying weatherproofing layer.

A scaffold cross-bar of metal with a round-tube carrier profile of steel includes a round tube and has an outside diameter, and a U-shaped reinforcing profile of steel sheet. The U-shaped reinforcing profile has a base profile and two parallel profile legs which extend away from the base profile in the same direction at a transverse spacing from one another. Each profile leg has at least one opening for fastening and/or securing scaffold components on the scaffold cross-bar. The transverse spacing of the profile legs is smaller than 0.6 times the outside diameter of the round-tube carrier profile.

The present invention provides a fastening unit for attaching a first beam to a second beam, wherein the second beam is arranged substantially perpendicularly to the first beam, the fastening unit having a first axis and a second axis, wherein the second axis is substantially perpendicular to the first axis. The fastening unit comprises a connecting member extending in a direction parallel to the first axis of the fastening unit and having a first edge portion, a second edge portion and a central portion, the connecting member further comprising a coupling element.

A scaffolding has a coupling which can be mounted at a connection location. The connection location in this instance has a recess in the form of a through-recess in which an angular portion of the coupling can be at least partially introduced. The angular portion engages partially behind the connection location. The coupling may have a half-coupling so that a simple connection to a scaffolding pipe, in particular for connecting to a facade, is produced. A method for connecting the scaffolding to such a coupling is also taught herein.

The present invention discloses a shoring apparatus, a system incorporating the apparatus, and a related method utilizing the apparatus in the system for an improvement in conducting concrete edge repairs in multi-story buildings. The shoring apparatus includes a structural member and attachment features that are configured to make the shoring apparatus attachable to the underside of a concrete structure that is to undergo edge repairs. The shoring apparatus is advantageous over shore poles in that they securely support the concrete form without relying on a lower structure to counter the load of the structural repair.

A scaffold transom, particularly for the horizontally oriented installation in a scaffold section, the scaffold transom comprising at least one transom support which is rod-shaped and extends in the direction of a longitudinal axis, the transom support having two opposing ends in the direction of the longitudinal axis, and a connection interface being located at each of these two ends, which connection interface is provided for the connection to a scaffold element, at least two brackets which each extend along a bracket axis, the brackets each having two opposing ends in the direction of their bracket axis, one of said ends of each bracket being connected to the transom support, and at least two closures respectively one of which is located at the end of a bracket opposite of the connection of said bracket to the transom support.

A scaffolding pipe of a structural scaffolding system extends from a first axial pipe end to an opposing second axial pipe end. A receiving portion is provided on the first axial pipe end and an insertion portion is provided on the second axial pipe end. The insertion portion has a reduced cross-section compared with the receiving portion and terminates with a radial shoulder which forms a support face. The receiving portion inner diameter is greater than the insertion portion outer diameter. The receiving portion at the first axial pipe end has one positioning groove which is interrupted or continuous in a peripheral direction which reduces the inner diameter of the receiving portion and which defines the minimum inner diameter of the receiving portion. A pipe wall of the scaffolding pipe has at the first axial pipe end a maximum wall thickness greater than the otherwise smaller wall thickness.

A coupling member includes a hook-shaped coupling part arranged to be hooked into a gripping part of an upright and a locking arrangement switchable between a locking position and a release position. Further, the locking arrangement includes a pivotally attached first clamping part and a wedge-shaped locking part, which is slidable between a locking position and a release position. The wedge-shaped locking part is arranged to push the first clamping part towards the upright and the gripping part by means of wedge action. Moreover, the first clamping part comprises two transversally spaced apart side parts which jointly define a cavity there between. The first clamping part is arranged externally on the hook-shaped coupling part, and is arranged partly within the cavity. Further, each of the side parts includes fastening means for pivotal attachment of the first clamping part to the hook-shaped coupling part.
