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 includes a method of building an offset scaffold platform to an existing scaffold structure by using pivoting horizontal scaffold truss members, where each truss has a first end with a pivoting connector that pivot vertically and second ends that have second connectors that pivot horizontally. Each pivoting connector has a movable latch that, when latched, restricts uncoupling from a coupled vertical scaffold member but allows the pivoting coupled truss to remain moveable about the pivoting connector. The method includes the step of connecting one truss to a vertical scaffold member in an existing frame about the vertically pivoting end and connecting the second truss to another vertical scaffold member in the existing scaffold structure about one of its pivoting ends. Each pivoting connector latch is moved to the latched position, each truss is pivoted about its coupled end, and the uncoupled ends are each connected to vertical scaffold members which are supported from an overhead structure. Scaffold boards are positioned between the pivoted trusses to create a working surface therebetween.

The invention relates to a support (1) for supporting a structure region, comprising a central part which has a hollow profiled rectangular tube (8) and two end parts (4), wherein each of the end parts (4) is arranged so as to be telescopable out of the central part from open ends (9) of the hollow profiled rectangular tube (8) in order to change the length of the support (1). Each of the end parts (4) has a hollow profiled round tube (2, 3), and inner wall regions (21) of the hollow profiled rectangular tube (8) form guides for the hollow profiled round tubes (2, 3). The hollow profiled round tubes (2, 3) can be guided in the central part in the longitudinal direction of the hollow profiled rectangular tube (8) by means of contact region (22) lying against the guides so as to achieve the telescopability of the end parts (4).

One embodiment of the invention is a horizontal scaffold truss that has upper and lower horizontal scaffold members offset but fixedly joined with braces. Each upper and lower members have a connector positioned on each end of the respective lower and upper members, where at least one of the connectors is pivotally mounted on the respective lower or upper connector, and the connecters are engageable with an annular member positioned on a vertical scaffold member.

An individual scaffolding post made of metal for facade scaffolding or of facade scaffolding has secured thereon a single rosette for detachably securing at least one horizontal bar. A railing securing device is secured above the rosette, on which a railing strut is detachably supported. The railing securing device includes a rigid bracket permanently secured to the post, which together with an outer surface of the post surrounds and engages around a vertical receiving slit through-opening. A railing rod end of the railing strut has a first recess on the underside, which is open to side surfaces of the railing rod end extending away from one another and is open downwards. The railing rod end has a mounting hook limiting a first recess and partially surrounding same with its free hook end extending to the rear. The free hook end engages behind the bracket contact part of the bracket.

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 fastening unit for attaching a first beam to a second beam is provided, 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.

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.

A connector for temporary scaffolding at an end of a lateral member, to be wedge-connected to a receiver around a strut, includes: a wedge body provided movably at the end of the lateral member upward and downward relative to the lateral member; a locking body including a claw formed such that, as a result of the wedge-body's moving downward, the claw could travel from initial to locking position with respect to the receiver; and a biasing body capable of pressing the locking body toward the wedge body, wherein the wedge body includes a shoulder protruding toward the locking body, the locking body includes an interfering portion protruding toward the wedge body, and when the claw is at the initial position, the shoulder is blocked by the interfering portion from moving upward, thereby preventing the wedge body from moving upward and the locking body from traveling toward the biasing body.

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).
