Abstract (en)

[origin: EP0136906A2] An adjustable arch support used for the laying of brickwork, lamination of timber beams, or other similar uses which incorporates a flexible band (3) supported by a number of telescopic struts (2) from a central hub (1). The shape of the arch is determined by adjustment of the struts (2), bending the band (3) to the desired configuration. The band (3) incorporates at least one lockable hinge (4) allowing the band to be set either to an even curve or to a discontinuous curve having a peak at the hinge for the formation of Gothic arches, etc.
