COLLAPSIBLE UTILITY SCAFFOLD
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.
HANDRAIL, SCAFFOLD, METHOD OF ERECTING A SCAFFOLD AND USE OF A HANDRAIL IN A SCAFFOLD
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.
CROSS BRACE AND MODULAR FURNITURE
The invention relates to a cross brace (4) comprising an elongate bar portion (41) and two clips (42). The bar portion (41) has two substantially opposite longitudinal ends. The two clips (42) are each arranged on one of the two longitudinal ends of the bar portion (41) and are designed to almost fully enclose a bar-shaped element (22, 52). Furthermore, the two clips (42) can each be brought into an opened position, in which the bar-shaped element (22, 52) can be received by the clip (42) and removed from the clip (42), and into a closed position, in which the bar-shaped element (22, 52) can be fully enclosed by the clip (42). The clips (42) have a lock (425) which locks the clip (42) in the closed position.
CROSSMEMBER, CROSSMEMBER SET, AND FURNITURE KIT
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).
Ladder cage latching members and methods of use
A rapid release and rapid install latching member for use with ladder cages to couple the cage rings is provided wherein the latching members are capable of retaining the cage ring connecting members thereon without the use of external fasteners. The latching members are designed such that they may be removed from or installed on the ladder cage while the ladder cage is installed at the work site or otherwise for quick and easy repair or replacement. An exemplary ladder cage contains a plurality of ring members having a plurality of latching members interspaced around the circumference thereof, with adjacent ring members being coupled to each other through the interaction of cage ring connecting members with the latching members.
SCAFFOLDING TRUSS
A scaffold truss comprising a hollow, rectangular upper horizontal member having vertical side walls and top and bottom walls; a hollow, rectangular lower horizontal member having vertical side walls and top and bottom walls, the lower horizontal member being separated from the upper horizontal member; a plurality of diagonal bracing members to fixedly join the upper horizontal member with the lower horizontal member, each of the plurality of diagonal bracing members forming an X-shape with another diagonal bracing member; and a plurality of vertical members to fixedly join the upper horizontal member with the lower horizontal member; wherein a thickness of the vertical side walls of the horizontal members is greater than a thickness of the top and bottom walls of the horizontal members.
Crimping Tool, Crimped Pipe with Flattened End, and Scaffold Ladder Frame
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.
Clamp for connecting ledger to shoring post
The disclosure is directed to a clamp for connecting a ledger to a shoring post. The clamp includes a base member, a ledger-connecting member, and a first jaw, which are fixed connected to each other. The clamp includes a rotatable member inserted into the base member, which is rotatable and slidable in the base member along a longitudinal axis. A portion of the rotatable member is accessible via the slot of the base member. The clamp includes a second jaw fixedly connected to the rotatable member. The clamp further includes a wedge, and when the wedge is inserted into the slot of the base member to engage the rotatable member in a lock position, the first and second jaws are locked to capture two sides of a shoring post.
