Abstract

1469092 Work supports W G MOEHLENPAH 12 Dec 1975 [20 Dec 1974] 51098/75 Heading B4X Apparatus for use in the fabrication of wood structures such as roof trusses S. comprises a plurality of movable stands 9 having means 11 for clamping the wood members W together-for nailing at their intersections, at least one of the stands 9 having: a pair of legs 14a, 14b engageable with the floor surface 13 the legs being located adacent an "outside" face of the-stand and electromagnetic hold down means 17 also engageable with the floor surface and located. adjacent an "inside" face of the stand, the-floorsurface being of magnetizable material, e.g. of steel plates 13, and means, such as retractible ball castors 15, whereby the stand may be lifted so that the legs 14 and magnetic hold downs 19 are clear of the floor and the stand then moved to its required location. The location of the electromagnetic hold downs (of which there are two on each stand 9) adjacent the "inside" face of the stand is stated to be advantageous in resisting tipping forces exerted on the stand by wood members W. A guide rail 59 may be secured to the floor to assist in aligning those stands 9 which support the lower chord of a truss and a. power cable 55 supplies power for the electromagnetic hold downs, a switch (57) on each stand. providing for selective actuation of the hold-downs.
