Abstract

1,141,631. Formwork. A. HAIDER. 4 Feb., 1966, No. 4937/66. Heading E1S. Formwork for forming window openings in concrete walls comprises corner pieces 1-4 and straight pieces 5-8. The various pieces are connected together by pins 9 and holes 16 and pivoted latches 11 co-operating with lugs 12. The end faces of the corner piece 1 are bevelled at 45‹ so that in disassembly of the formwork, the corner piece 1 is withdrawn in the direction of the arrow A. The end faces between all the pieces except 4 and 8 and 8 and 3, which are at right angles, are bevelled at 45‹. The formwork is provided with corner plates 13 by which it is secured to the main wall formwork. The formwork is stripped at 25 to provide a shoulder for the window frame to rest against and the portion 26 of the lower part of the formwork is inclined downwardly to assist withdrawal of the formwork.
