A catwalk system having a pair of side trusses formed of a top chord and bottom chord connected by a plurality of vertical posts and diagonal posts. The bottom chords have a plurality of joints formed of a bottom plate, opposing side plates and wing plates that form a pocket. These pockets receive an end of floorbeams which are bolted to the side plates. The bottom plate also includes a wind brace section that receives an end of a diagonal wind brace therein. The fabricated side trusses are shipped to the job site where the catwalk is quickly and easily assembled by aligning a pair of side trusses in parallel space alignment and installing floorbeams in the pockets of opposing joints. To provide additional rigidity diagonal wind braces are installed in a zig-zag formation between diagonally opposite joints. This arrangement provides a quickly assembled catwalk that requires minimal assembly.

A kit for erecting a platform. The kit comprises a plurality of quad-chord trusses. Each truss is attachable to others of the truss by eyelets on the ends of the chords. When the chords are spaced horizontally, the eyelet apertures are vertical for receiving pins, which allows a single pin to be inserted in eyelet apertures on one side of the truss so that one truss is swingable horizontally into position for rigid attachment end-to-end by inserting another pin in eyelet apertures on the other side of the truss. Each truss comprises a plurality of connector members for attachment to the trusses along their lengths. The kit further comprises a plurality of cross beams having connector members at their ends to mate with and attach to the truss connector members, and a plurality of tie-up mechanisms attachable to the trusses and to which a supporting line from an overhead structure is attachable. The cross beams have overhangs at their ends for overhanging the upper ones of the chords to allow ease of movement along the chords and attachment. A track lies between the chords of each truss to allow movement of bolts along the track into position for insertion into decking apertures for attachment of the decking. The trusses may be foldable for transport and storage.

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 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.

A scaffold connection element for coupling two scaffold members, the scaffold connection element including: a first receiver configured to receive at least part of a first scaffold member; a second receiver configured to receive at least part of a second scaffold member with the first and second scaffold members substantially parallel with each other and/or co-axial with each other; and a depth adjustment arrangement configured to adjust a depth of the first receiver, such that the depth adjustment arrangement is useable to alter a distance between the first and second scaffold members received by the scaffold connection element.

The invention relates to a frame element (10) comprising a frame pipe (12) into which a threaded spindle (16) is partly introduced at one end. The threaded spindle (16) is guided in the frame pipe (12) by at least one spindle positioning groove (24, 26, 28), in particular multiple spindle positioning grooves (24, 26, 28). The frame pipe (12) is mechanically reinforced by the spindle positioning groove(s) (24, 26, 28) in the region of the threaded spindle (16) received in the frame pipe (12). At the same time, the maximum inclination of the threaded spindle (16) in the frame pipe (12) is reduced by the spindle positioning grooves (24, 26, 28). Overall, a force can thus be substantially more strongly applied to the frame element (10) in the direction of the longitudinal axis (23b) of the frame pipe (12). At the other end, the frame pipe (12) has at least one pin positioning groove (40, 42), in particular multiple pin positioning grooves (40, 42). Alternatively or in addition thereto, the frame pipe (12) can have at least one reinforcing groove in the region of a node point. Alternatively or in addition thereto, the frame pipe (12) can have at least one additional reinforcing groove between two node points.

An improved latchable scaffold board having a board like member with fixed clips or brackets fixedly attached at each end of the board. The brackets are shaped to engage and capture a horizontal scaffold member. The board also has a movable latch at least one end that moves to a latched position, and in the latched position, the movable latch has a portion that is positioned below the horizontal scaffold member, thereby trapping the scaffold board to the horizontal scaffold member.

A coupling system (10) for coupling together elongate members (6) is described. The coupling system (10) comprises a mounting member (1) having a mounting surface (8). A first locating member (2) is mounted on the mounting member (1) and a second locating member (2) is adapted to be mounted on the mounting member (1), in use. A number of support members (3) are provided and each support member (3) comprises two locating member engagement formations (31, 32), a mounting member engagement surface (27) and a first elongate member support formation (28). The engagement surface (27) of a support member (3) is adapted to be engaged with the mounting surface (8) of the mounting member (1) and one locating member engagement formation (31, 32) is adapted to be engaged with each locating member (2) to mount the support member (3) on the mounting member (1).
