Abstract
668,378. Clamps for shuttering and scaffolding. KWIKFORM, Ltd. Jan. 10, 1950. [Jan. 11, 1949] No. 789/49. Class 20(ii). [Also in Group XXV] A clamp for securing a flat sectioned bar or a flanged member 13, Fig. 2, to a transversely extending supporting member 17, comprises a channel or U-section member 19 clamped to the member 17 by a screw 23, the member 19, Fig. 4, carrying a pair of spaced lugs 25 receiving between them the web 15 of the member 13 which is secured by a screw 27 at varying angles of inclination to the supporting member. The screw 27 bears at one end on the web 15 or may pass through aligned holes in the lugs 25 and web 15. The clamp may be used in securing together members of a supporting structure for shuttering in the erection of a concrete arched roof as described in Specifications 668,371 and 668,379. Where a tube 36, Fig. 6, which may form part of a scaffolding structure, is required to be secured transversely to the supporting member which may be in the form of a tube, a jaw 34 carrying a clamping screw 35 is provided on the head 33 of a short T-member having its web 31 secured between the lugs 25 of the clamp as above described. The jaw 34 may be of rectangular form to receive a timber 39, Fig. 7 (not shown). Specification 574,457 is referred to. The Provisional Specification also refers to Specification 668,372.
