Definitions

  • the invention relates to a device for a scaffold of the kind comprising vertical struts or spires, horizontal struts which may be cantilever struts each supported by a diagonal strut which, at each end, is provided with fasteners for connection to rims on horizontal struts and spires in the junction points of the scaffold, and where the interconnection between diagonal strut fastener and rim is secured by means of a locking means, which may have the form of a wedge or another insertion means, e.g. a bolt passing through registering wedge/bolt accommodating hole portions of holes in diagonal strut fastener and rim.
  • the wedge acts as a force transferring means for pressure forces and accommodates the entire pressure load. Consequently, the wedge must be dimensioned correspondingly and, therefore, it becomes voluminous and heavy.
  • Each wedge is connected temporarily (prior to the mounting) to the diagonal strut fastener, and during the mounting the wedge is often operated manually from the opposite end of the diagonal strut, and a heavy wedge will then be rather unwieldy.
  • a primary object of the present invention has, therefore, been to design and shape the diagonal fastener such in relation to adjacent elements and members of the scaffold that transfer of pressure forces between diagonal strut and horizontal strut/spire is secured, without loading the wedge the bolt or a similar connecting insertion means in the junction point of the scaffold.
  • the diagonal strut fastener is formed with land areas adapted to come to rest pressure force transferringly against faces on the horizontal strut/spire and against a face on said rim.
  • a land area thereon is pressed against the rim with a contact creating pressure, in order to secure an efficient pressure force transfer.
  • the insertion means (wedge/ bolt) which is to secure the interconnection of the diagonal strut fastener and the rim and which, to this end, becomes inserted through their registering hole portions, is connected such with the diagonal strut fastener that said insertion means is carried by the diagonal strut fastener, following the same during the installation.
  • the invention does not require that a substantial real wedge action takes place, so that a bolt having a uniform cross-section may be used; the insertion means, e.g. the wedge, exhibiting a hook at the upper end in order to prevent that the wedge get stuck within the diagonal strut fastener prior to the latter being attached to a rim.
  • the opposite end of the wedge may have a lateral tube rivet which, in the connection position, is to accommodate a split pin.
  • the tube rivet has a larger axial length than the width of the upper hole in the bifurcated diagonal strut fastener, and the lower end of the wedge can, consequently, not get lost by being pulled upwardly.
  • the lower hole i.e. the hole in the lower branch of the bifurcated diagonal strut fastener, will, of course, have so large dimensions in the lateral direction of the wedge that the wedge's lower end and its tube rivet may pass therethrough.
  • a diagonal strut may be handled in such a way that the operator holds one end of the diagonal strut while he tries to interconnect its upper fastener carrying the wedge and an overlying rim on a spire, the lower end of the latter occupying a position above the ground and being connected to the outer end of a jetting-out strut.
  • the branches of the bifurcated strut fastener are to be placed one above and one below the rim, three wedge accommodating hole portions vertically aligned; moreover, the lower end of the wedge must simultaneously take a position immediately above said hole of the rim. This is very difficult to manage by traditional scaffold components.
  • the wedge, bolt or another connecting insertion means may be formed such that it has a first longitudinal portion forming an obtuse angle in relation to the another longitudinal portion.
  • Such an angled/curved wedge/bolt may, prior to the mounting, be tilted rearwardly and take a temporarily stable position of readiness, so that the lower end carrying the tube rivet occupies the desired position just below the upper branch of the bifurcated diagonal strut fastener.
  • the diagonal strut fastener through the strut may be subjected to an appropriate displacement movement, during which the diagonal strut fastener for instance impinges slightly against the adjacent spire portion, putting the upwardly extending, rearwardly swung portion into an adequate motion, so that the wedge falls into position within the registering hole portions of the holes in the bifurcated diagonal strut and the hole in the rim.
  • Figure 1 shows a perspective partial view illustrating adjacent components, respectively portions thereof, which may be incorporated in a scaffold junction point;
  • Figure 2 shows the diagonal strut fastener coupled to the end portion of the diagonal strut, seen separately in side elevational view;
  • FIG 3 shows the same as figure 2, seen from above;
  • Figure 4 shows the same as figure 2, but here the wedge is not only passed through the wedge accommodating hole in the upper branch of the bifurcated diagonal strut fastener, but also secured against being pulled out through said hole; additionally, the wedge's upper angled portion is tilted rearwardly so that the wedge takes a position of readiness, from where it may be put into motion forwardly, in order to get it to fall down into the hole of the rim as well as into the corresponding hole portion of the bottom branch of the bifurcated fastener.
  • a diagonal strut 1 is connected to a bifurcated diagonal strut fastener 2 by means of a lateral bolt 13.
  • the diagonal strut fastener's 2 upper branch is indicated at 2' and the lower one at 2".
  • the branches 2', 2" of the bifurcated fastener 2 are each formed with a wedge accommodating, vertically through-going hole 3' and 3", respectively, which in size and shape is adapted to accommodate a wedge, generally denoted by means of the reference numeral 4, said wedge 4, in the position of use, figure 1, takes a substantially vertical position.
  • the wedge 4 is curved repectively angled in the longitudinal direction and, in the position of use, has an upper portion 4' and a lower portion 4", said portions 4', 4" forming an obtuse angle with each other.
  • Figure 4 shows how the wedge's curvature/angular course can be utilized.
  • the wedge is tilted rearwardly (in relation to the junction point of the scaffold, figure 1) , taking a position of readiness, from where it with relative ease should be tilted forwardly in order to fall down into vertically registering hole portions of holes 3 ' , 3" in branches 2', 2" of the bifurcated fastener 2 and an intermediate hole 5 in a rim 6 on a scaffold spire 7, figure 1.
  • wedge 4 is provided with a lateral tube rivet 8 which is placed in a hole in the wedge subsequent to the passage of the lower portion 4" of the wedge 4" through the hole 3' of the upper branch 2' , so that the wedge 4 thereafter can not be pulled out of its engagement with the diagonal strut fastener 2, whereafter wedge 4 and diagonal strut 1,2 constitute an assembly facilitating the subsequent mounting operations.
  • the diagonal strut fastener 2 is formed with land areas 10, 10', 11, 11' adapted to rest pressure force transferringly partly against a face 7' on th spire 7 and partly against a face 6' on the rim 6.
  • first land areas 10, 10' on the diagonal strut fastener 2 are formed on the outer end edge of the two branches 2', 2" in the form of projecting mouldings engaging into vertical grooves or flutes formed in the opposing rim portion and the bottom portion thereof forming a land area.
  • Second land area 11 forms an angle differing from a right angle with a vertical plane through the wedge accommodating holes 3', 3" of the branches 2', 2".

Abstract

Un échafaudage est composé d'entretoises verticales ou flèches (7) et d'entretoises horizontales, qui peuvent être des entretoises formant saillie, portées chacune par une entretoise diagonale (1), dont chaque extrémité est pourvue d'un dispositif de fixation (2) servant à réaliser un accouplement aux bords (6) d'entretoises horizontales ou flèches (7) au niveau des points de jonction de l'échafaudage. L'accouplement entre le dispositif de fixation (2) de l'entretoise diagonale et le bord (6) s'effectue par l'intermédiaire d'un moyen de verrouillage, lequel peut se présenter sous la forme d'une clavette (4) ou d'un autre moyen d'accouplement par insertion, par exemple, un boulon s'introduisant à travers les perçages correspondants (3', 3', 5) du dispositif de fixation (2) de l'entretoise diagonale et du bord (6). Le but de l'invention est de réaliser un dispositif de transfert de forces de compression consistant à ne pas charger la clavette (4) ou à la charger au minimum. A cet effet, le dispositif de fixation (2) de l'entretoise diagonale comporte au moins une première zone d'appui (10, 10') de la force de compression, afin de la transférer contre une partie avant contiguë et opposée (7') d'une flèche (7), ainsi qu'au moins une deuxième zone d'appui (11) de la force de compression, afin de la transférer contre une partie avant contiguë et opposée (6') du bord (6) de la flèche (7).
