Abstract

1338660 Screw sockets FOSROC AG 30 June 1972 [1 July 1971] 30930/71 Heading F2M A method of securing a bolt 5 is a concrete railway sleeper 1 comprises securing a plastics sleeve 9 in a bore 3 in the sleeper using a settable resin composition 11, and then engaging the bolt 5 in the sleeve 9. As shown, the sleeve 9 replaces part of a rotten wooden plug 4, the upper portion of the wooden plug being removed and the hole in the remaining portion being covered by a thin disc 7 prior to introducing the resin. The sleeve may have external circumferential ribs, and has a thin wall 10 across its lower end. As the bolt 5 is driven into the sleeve, it pierces the wall 10 and the disc 7. The sleeve may be of a polyamide, polyacetal, polypropylene, or polycarbonate. The resin, which is introduced in a rupturable cartridge 8 or by direct injection, is preferably an unsaturated polyester resin with a redox catalyst system hardener, or an epoxy resin with an acid-free catalyst.
