Definitions

  • This invention relates to structural members of the type which are formed with apertures therein and, in particular, it relates to a device for permitting connection of structural components to such structural members.
  • Soldiers are used in many different applications. In particular, they are employed to provide backing for formwork and are used in heavy-duty shoring applications, for side bracing, gantry support and cantilever parapet formwork.
  • soldiers have also been increasingly employed as scaffolding, a scaffold framework being constructed from interconnected horizontal and vertical soldiers.
  • other structural components need to be connected to the soldiers. For example, it is often desirable to provide bracing for the soldiers, particularly when they are used for scaffolding.
  • a flat plate is welded across a pair of aligned holes in the soldier.
  • the flat plate has a hole therein through which one end of a bracing rod can be passed, the bracing rod then being secured in position by attaching a nut to its end.
  • the bracing rod extends from the soldier between the webs thereof and its movement is constrained by these webs.
  • the arrangement therefore, only permits bracing of either two horizontal soldiers lying in different vertical planes, or of two vertical soldiers, the hole axes of which lie in different vertical planes. It does not permit bracing of two horizontal soldiers in the same horizontal plane, nor does it permit bracing of two vertical soldiers, the hole axes of which lie in the same vertical plane. The arrangement therefore does not permit full bracing of a structure composed of interconnected soldiers.
  • Arrangements which allow bracing of two vertical soldiers whose hole axes lie in the same vertical plane, known, and hereinafter referred to, as “facade bracing", or of two horizontal soldiers lying in the same plane, known, and hereinafter referred to, as "plan bracing".
  • fin bracing or of two horizontal soldiers lying in the same plane, known, and hereinafter referred to, as "plan bracing”.
  • a length of tube of the appropriate size is prepared for use as a brace by cutting its ends diagonally across so that it will fit between two soldiers to be braced. The ends are then welded to plates, which in turn, are bolted to the sides of the soldiers.
  • French Patent FR-A-745718 describes scaffolding or formwork for use in the construction of curved walls.
  • the scaffolding includes support members which, in use, are vertical and serve to support panels between which the wall is formed.
  • Tie rods can be secured between oppositely positioned support members by connectors comprising a pair of spaced wings which receive a bulb-shaped head secured to an end of the tie rod.
  • the head in turn has a slotted strip which extends therefrom between the wings and through a first wedge, a second wedge extending through the slot serving to press the first against the wing edges to thereby make the connection.
  • the support members are in the form of spaced beam pairs and, as in the first arrangement discussed above, the tie rods extend out from between the beams and are constrained thereby.
  • the invention comprises the combination of a support member having at least one hole therein, at least one rod member and at least one connector for securing the rod member to the support member, the connector comprising a body member and means for releasably mounting the body member to the support member at or adjacent a hole therein, the body member including a cavity and a bearing surface for a fixing means which, when releasably secured to the rod member and bearing against the bearing surface, connects the rod member to the body member with part of the rod member located in or passing through the cavity in the body member, characterised in that the support member is a soldier, i.e.
  • the rod member when secured to the soldier, extends through the hole at or adjacent which the body member is mounted at an angle to the axis of the hole and in that the fixing means is a nut, the location of which along the bearing surface sets the angular inclination of the rod member to the hole axis.
  • the combination allows bracing to be positioned in any desired diagonal orientation across a bay of a structure of which the soldier forms a part and further serves to ensure that bracing will not introduce secondary stresses into the structure. Furthermore, if the rod member is not to be used as a brace but instead forms part of some structural component to be connected to the soldier, it allows the structural component to be held in position at a particular desired angle relative to the soldier.
  • both facade bracing and plan bracing of a structure formed from interconnected soldiers are possible. Any length of brace may be employed and there is no need to specially shape the ends thereof.
  • a suitable rod member of approximately the correct length can be secured between two soldiers with the length between the attachment points being exactly as required for the particular bay to be braced, the ends of the rods being accommodated in the cavities in the connectors.
  • the bearing surface on the body member can be arranged so that the rod member can be set in any one of a number of particular different angular orientations relative to the soldier.
  • the bearing surface may be such that the rod member can be positioned at between 0° and 45° either side of the axis of the soldier hole, at or adjacent which the connector is secured, within the plane containing the axis of the hole and the axis of the soldier or, alternatively, within the plane to which the soldier axis is normal.
  • the body member may comprise a pair of wings spaced apart to define the cavity, a portion of the wings edges defining the bearing surface.
  • a rod member may be used as a brace whose length is greater than the required bracing length.
  • the wings serve to restrain the rod member whilst it is being secured in position by tightening down of a nut onto the bearing surface defined by the wings.
  • the body member is preferably mounted on the soldier in such a way that the wings lie on either side of a diameter of the main hole in the soldier at which the connector is mounted and are evenly spaced therefrom. Suitably the diameter is that which is parallel to the axis of the soldier.
  • the mounting means may comprise a plate to which the body member is attached and which, in turn, is connected to the soldier by the small holes either side of a main hole. thereof, suitably by bolting.
  • the mounting means may comprise a tubular member, to which the body member is attached, which locates in and bears against the walls of the main hole of the soldier at which the connector is mounted. The provision of a surface on the mounting means which bears against the main hole at which the connector is mounted gives good load transferal via the connector.
  • Whichever form the mounting means takes it suitably includes cutouts or slots so positioned as to allow passage of the rod member therethrough. This increases the size of the angle at which the rod member may be mounted relative the soldier hole axis.
  • the connector 2 comprises a body member 4 in the form of two wings 6.
  • Each wing 6 consists of a generally arc-shaped segment 8 and two leg sections 10.
  • the wings 6 are attached to a plate 12 by welding their legs 10 to the plate 12.
  • the plate 12 has a hole 14 therein and the wings 6 are mounted on the plate 12 across the hole 14 on either side of a diameter thereof so that they are spaced apart and define a gap therebetween.
  • the plate 12 has a second smaller hole therein 16 by which it can be mounted on a soldier, the plate 12 being secured to the soldier by passing a bolt through the hole 16 and one of the small holes provided by the soldier.
  • the dimensions and positions of the holes 14 and 16 in the plate 12 are so arranged that when the plate 12 is mounted on a soldier, the hole 14 aligns with and lies above a main hole of the soldier.
  • the wings 6 are so positioned that the diameter of the hole 14 on either side of which they are located is parallel to the axis of the soldier.
  • the connector 2 further comprises a tubular member 18 welded into the hole 14.
  • a tubular member 18 welded into the hole 14.
  • Figure 1 illustrates how a rod member 22 can be connected to a soldier by use of the connector 2.
  • One end of the rod member 22 is passed between the two wings 6 and through the hole 14 in the plate 12, the main hole of the soldier at which the connector 2 is mounted, and, the tubular member 18.
  • the rod 22 is moved until it is at the required angle relative to the axis of the soldier main hole through which it passes, the wings 6 serving to constrain it to move within a plane defined by the axis of the soldier and the axis of the main hole thereof.
  • the rod 22 is secured in place by tightening a nut 24 up against the curved surface of the arcuate sections 8 of the wings 6.
  • a washer 26 may be positioned between the nut 24 and the wings 6.
  • the rod 22 is held by the nut 24 by virtue of interlocking threads provided on the two parts.
  • the curved bearing surface defined by the arcuate portions 8 of the wings 6 allows the rod 22 to be secured to the connector 2, and hence the soldier on which this is mounted, at a number of different angles relative to the axis of the tubular member 18 and hence that of the soldier hole.
  • cutouts 28 and 30 are provided on the plate 12, intersecting with the holes 14, and in the tubular member 18, at either end thereof. With the rod 22 positioned at the extremities of the curved surfaces of the wings 6 a portion thereof passes through these cutouts 28 and 30 as is illustrated in Figure 1.
  • the rod 22 can be attached at other orientations relative to the soldier.
  • it can be connected at any angle between 0° and 45° on either side of the axis of the main hole of the soldier at which the connector 2 is attached within a plane at right angles to that defined by the axis of the soldier and the axis of the hole by turning the wings through 90° from the position shown in the Figures, i.e., within a plane to which the soldier axis is normal.
  • the rod 22 may be part of a structural component to be connected to a soldier. However, most suitably the rod is of suitable strength and size for it to be used to brace a scaffolding or other structure formed from interconnected vertical and horizontal soldiers.
  • the connector 2 permits both plan bracing and facade bracing of such structures, as is illustrated in Figures 4 and 5 respectively.
  • Figure 4 shows four horizontally positioned soldiers 32 interconnected by some suitable joint 34 which also serves to connect them to four vertical soldiers 36.
  • a rod 22 is connected between, and braces, two connectors 2.
  • the rod 22 can be releasably connected to the connectors 2 and that the connectors 2 allow the rod 22 to pass therethrough, any length of rod 22 can be used and its ends do not have to be specially shaped.
  • the arrangement further accommodates any discrepancies in the construction of the soldiers 32 or of the structure formed by these and soldiers 36, since the portion of the rod 22 which extends between the two connectors 2 can be set at exactly the required length. Thus the rod 22 will not either pull the two soldiers 32a and 32b, between which it is connected, together or push them apart and so will not cause secondary stresses to be introduced into the structure.
  • Figure 5 shows a similar arrangement to Figure 4, but this time the connectors 2 are employed for facade bracing.
  • Two horizontal soldiers 32c and 32d, which are vertically spaced, are braced by a rod 22 connected between them by way of two connectors 2.
  • Figure 5 additionally illustrates by dotted line 38 one of the alternative positions in which the rod 22 could have been placed due to the freedom of angular orientation relative to the soldiers 32c and 32d provided by the use of the connectors 2.
