Abstract
1500221 Ties for mine arches HANDELS-UND INDUSTR1EBEDARF GmbH & CO KG 27 March 1975 [3 April 1974] 13075/75 Heading E1E Apparatus for securing together a plurality of mine roof support frames 1 to 5 comprises a number of tie rods 6 to 9 whose ends partly encompass elements of neighbouring frames, means 19, 21 25, 29 for coupling the ends of adjacent tie rods at the same support frame so as to enclose it, and means 10, 11, 13, 16 for applying forces to said neighbouring frames longitudinally of the tunnel at locations adjacent said tie rods to tension them. The tie rod ends 6a, 6b etc. extend perpendicular to the length of the ties and are interconnected either by threaded sleeves 17, 18, 19 and spacers 20, 20a; or by a plate 21 or 25 respectively secured to the ends by nuts 22, 23 or by wedges 28 engaging slots 26, 27; or by a clamp plate arrangement 29. The force applying means may comprise wooden struts 10, mechanical jacks 11, 13 or hydraulic jacks, Fig. 1. When an hydraulic jack is used, Fig. 4 (not shown) it may have forked ends, which engage over the tie rod ends, and it may be suspended from the tie rod.
