Definitions

  • This invention relates to a building arch support device and has been devised particularly though not solely as a modification of the arch support described in my Australian Patent No. 525,237.
  • DE-A-2 334 020 shows a configuration (particularly at Figure 10) wherein this problem is dealt with by providing a hinge in a flexible arch support band which is in turn supported by a number of telescopic struts from a central locking hub.
  • the invention consists in a device for supporting an arch during construction operations, comprising a hub member, a plurality of struts pivotally connected to the hub member and extending away from the hub member in one plane and in respective directions independently capable of adjustment relative to one another and relative to the hub member, an elongate load support band connected to the outer ends of the struts and adapted to support a load between the struts, said band being sufficiently flexible to permit alteration of the shape of the band upon adjustment of the struts and incorporating at least one hinge enabling the band to bend sharply through a predetermined angle in the said plane at the location of the hinge, characterised in that the hinge is lockable to retain said predetermined angle at the hinge.
  • said one or each lockable hinge is located in said band at the point of connection of the outer end of the strut to the band.
  • the lockable hinge comprises first and second hinge leaf members interconnected by a hinge pin allowing relative rotational movement along the axis of the pin between said hinge leaf members, an abutment extending from said first leaf member, and clamping means extending from said second leaf member adapted to engage and clamp said abutment to prevent relative rotation of said leaf members about said hinge pin.
  • said clamping means comprise two arms extending from said second leaf member on either side of said abutment and tension means adapted to draw said arms together to clamp said abutment therebetween.
  • said tension means comprise a bolt or stud extending between the free ends of said arms.
  • an arch support of the type described in my Australian Patent Specification 525,237 is constructed having a central hub or pin 1 (Fig. 3) from which radiate a plurality of struts 2 all substantially located in one plane.
  • Each strut is pivotally connected to the hub and is preferably telescopic or otherwise adjustable in length.
  • the outer ends of the struts are connected to an elongate load supporting band 3 which is typically a strip of sheet steel.
  • the elongate band 3 is provided with a hinge 4 at at least one point in the elongate band so that the hinge may be pivoted through a desired angle to achieve arch configurations in which the elongate band is discontinuous in its curve in at least one location.
  • a typical application is in the construction of a gothic arch as shown in Fig. 4 where the hinge 4 is located at the peak of the arch as can clearly be seen in Fig. 4. It is preferable although not essential that the hinge 4 be located at the free end of one of the struts 2 and preferably of the central strut 5.
  • the hinge comprises a first leaf member 11 and a second leaf member 12 which are typically formed by the ends of two segments of the elongate band 3.
  • the two lead members are interconnected by a hinge pin 13 at right angles to the plane of the struts allowing relative rotational movement along the axis of the pin between the hinge lead members 11 and 12 as is well known in conventional hinges.
  • the first leaf member is provided with an abutment 14 extending from the leaf member as shown in Fig. 1.
  • the abutment may be in the form of a section of steel bar welded to the first leaf member at 15 but in the preferred form of the invention the abutment is formed from two arms 16 and 17 solidly connected adjacent their free ends 18 by a pivot pin 19.
  • the second leaf member 12 is provided with clamping means in the form of two arms 20 and 21, typically welded to the second leaf member and extending outwardly therefrom on either side of the abutment 14.
  • the clamping arms 20 and 21 are provided with tension means in the form of a threaded bolt 22 and corresponding nut 23 interconnecting their free ends 24 so that the nut and bolt may be tightened causing the arms 20 and 21 to be drawn together and clamp the abutment 14 therebetween.
  • the nut and bolt 22 and 23 are loosened and the first and second hinge leaf members rotated relative to one another about the hinge pin 13 until the desired angle is reached.
  • the nut and bolt are then tightened, clamping the abutment between the arms 20 and 21 and preventing any further undesired rotation about the hinge pin 13. In this manner the desired angle for the hinge 4 may be preset in the elongate load supporting band 3.
  • the hinge 4 be located at the end of one of the struts 2 and to this end the typical strut 5 is pivotally engaged with the hinge by way of a hole 25 in one end of the strut engaging the pin 19 in the abutment 14. In this manner the end of the strut 5 is pivotally connected to the lockable hinge.
  • a modified arch support which enables a single arch support to be adapted by presetting the lockable hinge or hinges to give any desired configuration of arch.
