The horizontal structural part (20), in the joining area thereof, is provided with at least a through-hole(21, 24, 25) for receiving the wedge body (30, 31). The wedge body (30, 31) is formed with an upper main section (35) and at least a lower leg section (40) comprising, respectively, a first wedge-shaped leg (43) for being inserted between the hook means (27) and the cage arrangement (13) and a second impact leg (50) which, after the wedge body (30, 31) has been inserted, protrudes from and is accessible in a lower area of the coupling (1).
Abstract:
A scaffolding comprises elongate vertical members (6), elongate horizontal members (8) provided with connection members (12) by which the horizontal members may be connected to the upright members, and elongate diagonal braces (10) comprising mounting formations (42) adapted to be interfitted with receiving formations (32, 34) of the connection members (12). The mounting formation (42) is generally cylindrical, and is located substantially wholly within a cylindrical envelope containing the elongate portion of the brace, the longitudinal axis of the mounting formation intersecting the longitudinal axis of the elongate portion substantially at right angles, generally centrally of the mounting formation. The mounting formation is connected to the elongate portion by a cranked connection portion (44). The receiving formations (32, 34) are provided by bores (36), recesses being provided which open into the bores, in which recesses the connection portions (44) are located when the mounting formations (42) are positioned in the bores (36). This allows forces to be transmitted between the connection member (12) and the diagonal brace substantially on the longitudinal axis of the brace, over a range of angular articulation of the brace relative to the cross member. The connection member also comprises spaced limbs (14, 16) adapted to embrace a supporting formation (18) on the upright member, the limbs and supporting formation being provided with openings through which a wedge may be inserted to retain the cross member securely connected to the upright member. The opening of the upper limb is provided with a recess into which a projection (22) on the lower portion of the wedge (20) may extend, and an opening (26) extending from the recess (24), into which the lower end of the wedge may be located, a notch (28) being provided on the wedge which may be engaged with a corner (34) on the interior of the limb (14), to restrain inadvertent movement of the wedge from an inoperative position.
Abstract:
A releasably engageable builders scaffolding assembly comprises an upright member (10), cross members (16 and 18) and brace members (12 and 14) wherein a cross member and a brace member are connected to the upright member by means of a wedge (40) securing both said members to a socket (20) on the upright member. A cross member is connected to the upright member by means of a channel shaped connector straddling a socket and affording a space therebetween for the reception of a grooved spigot (58) extending from a brace member which spigot is retainable by the wedge (40) passing through the cross member connector and a socket.
Abstract:
Die Erfindung betrifft ein Anschlusselement für ein Keiltaschenmodulgerüstsystem aus einem Gerüstknoten (10). Am Ständerrohr (14) sind die nur im Ansatz dargestellten und nicht näher bezeichneten Keiltaschen angeordnet, in welche die Horizontalriegel (11) mit dem Keil (1) eingeführt werden und auf Grund der optimierten Geometrie sicher arretiert sind.

Abstract:
A scaffold comprises vertical struts or spires (7) and horizontal struts, which may be jetting out struts, each supported by a diagonal strut (1) which, at each end thereof, is provided with a fastener (2) for connection to rims (6) on horizontal struts and spires (7) in the junction points of the scaffold, and wherein the interconnection between the diagonal strut fastener (2) and the rim (6) is secured by means of a locking means, which may have the shape of a wedge (4) or another interconnecting insertion means, e.g. a bolt, passing through registering hole portions of holes (3', 3'', 5) in diagonal strut fastener (2) and rim (6). One has aimed at providing a pressure force transferring arrangement wherein the wedge (4) is not loaded or is loaded minimally. To this end, the diagonal strut fastener (2) is formed with at least one first land area (10, 10') for resting pressure force transferringly against an opposing, adjacent face portion (7') on a spire (7) and at least one second land area (11) for resting pressure force transferringly against an opposing, adjacent face portion (6') on the rim (6) on the spire (7).
