The invention relates to 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. The invention also relates to a scaffold portion comprising a scaffold node and further scaffold elements.

Problem to be solved

To provide an aluminum pipe support having lighter weight and higher rigidity compared to an iron pipe support.

Solution

An aluminum pipe support 1 is configured with two pieces of pins 2A, an inner pipe 3 having an outer periphery formed in any one of a regular hexagonal shape, a regular octagonal shape, and a regular decagonal shape, and having, at a position not subjected to insertion of the pin 2A, a cross-sectional area of 1.96 times or larger than a cross-sectional area at a corresponding position of an inner pipe of a targeted-size iron pipe support, an outer pipe 2 having an inner shape allowing the inner pipe 3 to be inserted into, and having, at a position not subjected to the insertion of the pin 2A, a cross-sectional area of 1.35 times or larger than a cross-sectional area at a corresponding position of an outer pipe of the targeted-size iron pipe support. The upper limits of the cross-sectional areas of the inner pipe 3 and the outer pipe 2 are set so that the total weight of the inner pipe 3 and the outer pipe 2 is lighter than the total weight of the inner pipe and the outer pipe of the targeted-size iron pipe support.

Effects

The specified load bearing capacity is satisfied, and drastic reduction in weight and high rigidity are achieved.

A modular decking system comprising a decking panel, a plurality of vertical supports, at least two first horizontal supports, at least two second horizontal supports arranged perpendicular to the first horizontal supports, one or more third horizontal supports arranged between the first horizontal supports and parallel to the second horizontal supports, and a plurality of connectors for detachably coupling the first and second horizontal supports, is disclosed. The connectors include an elongate tube adapted for insertion into the vertical supports and a connection hub. The connection hub and the ends of the first and second horizontal supports include reciprocating formations to enable the respective ends of the first and second horizontal supports to slidingly engage with the connection hub.

A horizontal scaffold member having a primary end connector and a secondary end connector. Each end connector is configured to couple to a cup or rosette on a vertical scaffold member. Each end connector includes a wedge assembly having a handle and a wedge, movable with respect to the connector to a latched and unlatched position. The primary wedge assembly has a primary and tertiary handles, with the tertiary handles connected to the secondary wedge assembly by a cable, and configured so that moving the primary and tertiary handles simultaneously to an unlatched position also moves the secondary wedge assembly to an unlatched position.

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.
