A utility scaffold is designed to be repeatedly broken down into straighter components to reduce the space requirement for storage and shipment. The scaffold has first and second ladder frames, each comprising a plurality of vertical supports, a plurality of horizontal supports, and a plurality of releasable connections. The horizontal supports are releasably connected to the vertical supports by the releasable connections to form a rigid ladder frame structure. The releasable connections include a male wedge protrusion and a female receiver configured to receive the male wedge protrusion. The female receiver has a passage therethrough, with the passage having a tapered interior surface. The male wedge protrusion and the tapered interior surface are configured to abut when the vertical support and the horizontal support are mounted together via the releasable connection. A fastener is optionally used to secure the releasable connection.

The invention relates to a pipe connection structure comprising a first component (2) and a second component (5). The first component (2) has a pipe portion (21) and the second component (5) is equipped with a pipe portion (51) and a pipe connector (7) which extends from a longitudinal end of the pipe portion (51) and can be arranged in the pipe portion (21) of the first component (2). The pipe portion (21) of the first component (2) and the pipe portion (51) of the second component (5) lie axially against each other when the pipe connector (7) of the second component (5) is arranged in the pipe portion (21) of the first component (2). The pipe connector (7) of the second component (5) is equipped with an actuatable locking clamping mechanism, which locking clamping mechanism of the pipe connector (7) of the second component (5) is designed to lock and clamp the pipe portion (21) of the first component (2) and the pipe portion (51) of the second component (5) together when the locking clamping mechanism is actuated while the pipe connector (7) of the second component (5) is arranged in the pipe portion (21) of the first component (2).

A crossmember (3) comprises an elongate rod portion (31) and two latching claws (32). The rod portion (31) has a central longitudinal axis, a first longitudinal end and a second longitudinal end substantially opposite the first longitudinal end. The first latching claw (32) is arranged at the first longitudinal end of the rod portion (31) and the second latching claw (32) is arranged at the second longitudinal end of the rod portion (31). The first latching claw (32) and the second latching claw (32) each comprise a gripping portion (321) shaped to correspond to a rod-shaped element (22, 31, 52) and are designed to be mounted on the rod-shaped element (22, 31, 52) without tools. The gripping portion (321) of the first latching claw (32) is offset from the gripping portion (321) of the second latching claw (32) with respect to the central longitudinal axis of the rod portion (31).

The invention relates to a system and method for determining and visualizing force flows in a bar supporting structure (1), which is preferably in the form of scaffolding, comprising a plurality of ladder or strut elements (5a-5c) which extend vertically and are set up in a disputed manner relative to one another and which are detachably connected via scaffolding couplings (7) to strut elements (6a-6d) extending diagonally and/or horizontally transversely thereto, wherein at least a load-critical part of the support elements (5a-5c) and/or strut elements (6a-6d) and/or scaffold couplings (7) of the bar structure (1) are provided with load sensors (8a-8c) for detecting static operating load values, the measured values of which are analysed in real time by a downstream analysis unit (9) for evaluating current load situations.

Disclosed is an arrangement including a staircase as well as walkway systems. The staircase includes a transitional member, and the walkways incorporate grate supports in order to facilitate the connection to adjacent structures. The arrangement also utilizes angled members which are configured with a reinforced flange existing in a dimension that has higher load requirements than the other flange. A novel step configuration is also disclosed.

An exemplary embodiment of the invention includes a first end section comprising a ladder section couple to a leg section by a horizontal extension coupling member, wherein the horizontal extension coupling member is in varying lengths to allow control over the width of the completed scaffold 10. Alternatively, the scaffold first end section may be coupled without the use of a horizontal extension coupling member. A completed scaffold may be accomplished by completing a first end section and a second end section and coupling the two with a cross-brass member that has been completed with the use of two loose brace members. Further completed scaffolds may be stacked upon each other. Planks or platforms may be utilized with the exemplary embodiments. Various kits are provided that provide for a full scaffold of varying widths. Kits may also contain additional materials such as planks, platforms, or additional horizontal extension coupling members to allow for a variety of widths of the finished scaffold.

A scaffold includes first and second ladder frames. Each ladder frame includes first and second vertical supports, and first and second horizontal supports mounted to the vertical supports. The first horizontal support is formed of tubular material, and has a base or central section and an asymmetric flattened end section. The end section is mounted to the first vertical support. The central section has a top centerline and a bottom centerline. The end section has a vertically elongated cross section compared to the central section. A top of the end section aligns with the top centerline of the central section; and a bottom of the end section is disposed below the bottom centerline of the central section. Related methods and tools are also disclosed.

A lightweight, multi-function scaffold includes an adjustable height platform that slidably mounts between two ladder frames. The side rails of the platform are reversible so that they can be mounted between the ladder frames in either a first orientation or in a second orientation. In the first orientation, the adjustable height platform is vertically movable between a first threshold and a maximum height. In the second orientation, the adjustable height platform is vertically movable between a second threshold and a minimum height. The ranges of movement in the first and second orientations may overlap.
