Abstract
A building foundation form work arrangement in which a plurality of boxes 1 are located on a supporting level surface and are kept apart to leave channels 4 between the boxes 1, and spacers 22 engaging respective sides of each of the corners of the boxes 1 so as to hold these in position against substantial lateral dislodgement forces when concrete is poured into the channels 4.
Claims15
A building foundation form work arrangement comprising:
- (a) a plurality of boxes located on a supporting level surface in spaced relationship so as to provide channels between adjacent boxes, each of said boxes having a plurality of vertical sides and corners formed at the intersections of adjacent sides, said channels being formed between adjacent sides of adjacent boxes;
- (b) spacers within said channels, between adjacent boxes, each of said spacers including (1) outermost planar surfaces which are adapted to engage the sides of respective adjacent boxes, and (2) frame members for holding said outermost planar surfaces, the lowermost edge of each such frame member being substantially above the lowermost edge of each such outermost planar surface;
- (c) said spacers including at least one spacer having a first pair of outermost surfaces engaging against both sides adjoining a corner of a first box and a second pair of outermost surfaces for engaging against both sides adjoining a corner of a second box which is adjacent to said first box.
A spacer for a building foundation form work arrangement wherein a plurality of boxes are located in spaced apart relationship to define therebetween channels, said boxes having a plurality of sides and corners formed at the intersection of adjacent sides, the spacer being characterised by including (1) first outermost planar engaging surfaces adapted to engage against both sides adjoining a corner of a first box, (2) second outermost planar engaging surfaces adapted to engage at the same time against both sides adjoining a corner of a second box adjacent the first box but spaced therefrom, and (3) a frame member extending between said first and second outermost engaging surfaces, said frame member having a lowermost surface which is substantially above a lowermost edge of each of the engaging surfaces such that concrete can extend contiguously beneath said frame member.
A spacer for a building foundation form work arrangement wherein a plurality of boxes are located in spaced apart relationship to define channels therebetween, said boxes having a plurality of sides, and corners formed at the intersection of adjacent sides, the spacer being characterized by including (1) outermost planar surfaces engaging against the sides of respective adjacent boxes, and (2) frames members for holding said outermost planar surfaces, the lowermost edge of each such frame member being substantially above the lowermost edge of each such outermost planar surface.
