Creation of Surface-Mounted Sills or Hobs on Cast-in-situ Concrete Building Slabs
Apparatus for the moulding of surface-mounted sills or hobs onto previously cast-in-situ concrete building slabs, said apparatus comprising two parallel, continuous side members, the upper and lower edges of each of which are turned inwardly through two 90* bends to create horizontally arranged upper first returns and lower first returns and vertically-arranged upper second returns and lower second returns, said side members being joined in a fixed spatial relationship by spacer elements welded to said upper and lower second returns to create a mould in the form of a long box more or less open at the top and bottom; said mould being secured to the upper surface of a previously cast-in-situ concrete building slab by a plurality of transversely-arranged clamping pieces in the form of flat strips of metal turned downwardly though 90* at each end to create legs of a length greater than the width of said side member lower second returns, the overall length of said clamping pieces being such that, when said clamping pieces are placed transversely within said mould, the outer end surfaces of said legs abut the inner surfaces of said side members, the lower edges of said legs abutting the upper surfaces of lower first returns; said clamping piece legs being urged against said lower first returns by a plurality of suitable masonry anchors, the lower parts of which are accommodated within suitable bores drilled into said concrete building slab, the upper threaded part of a wedging bolt of each said masonry anchor passing up through a complementary aperture in its complementary said clamping piece, nuts threaded onto said wedging bolt threaded upper parts being tightened against said clamping pieces, urging said mould side member lower first returns against the upper surface 5 of said concrete slab thereby securing said mould to said concrete slab.
