Abstract
923,882. Shuttering for casting concrete. A. FELDMANN. May 20, 1959 [May 20, 1958; Jan. 16, 1959; Feb. 5, 1959], Nos. 16115/58, 1612/59 and 4118/59. Class 20 (2). [Also in Group XXV] In a method of casting concrete on to or before shuttering, the shuttering is supported by a tie-rod 5, Fig. 1, and a push 3 of elastomeric material is positioned between shuttering 2 and a nut 4 fixed to the tie-rod, and surrounds a bolt 1, the head of which engages the shuttering, and the thread of which engages nut 4. After casting, and when the concrete has set, the bolt and shuttering are removed and the bush can then be pulled out to leave an undercut socket. The bush has a softer resilient part 7 surrounding a screwed insert 8 which may be bonded thereto. To remove the bush, the bolt is re-engaged with the insert, and pulled. In another arrangement, bush 3, Fig. 4, contains a tube 45 with a head 46 at one end and an internal thread at the other. To remove, a screwed member is engaged with the internal thread, and pulled. In a modification, bush 3, Fig. 3, is partly lined by an insert 37 having bayonet slots to receive an extracting tool. In use, the bolt passes through a distance-piece 36 formed by a wire helix. Specification 733,784 is referred to. Reference has been directed by the Comptroller to Specification 866,164.
