Abstract
A shuttering system and a method for its assembly, employing metal uprights which are arranged to face each other in pairs and have fixing means spaced along the uprights on their sides facing the casting cavity. Stringers are inserted in removable hooked coupling elements attached to the fixing means, and panels are attached to the stringers to form two opposing shuttering surfaces. The panels are fixed to the stringers by nails or the like which are driven into parts of the stringers made from a soft material such as wood.
Claims10
In a shuttering system for casting a concrete wall or partition comprising:
- metal uprights arranged to face each other in two spaced-apart rows;
- respective panels fastened to said uprights of each said row to form a pair of flat opposing surfaces which define a casting cavity for said concrete;
- respective adjustable support means associated with each said upright in one row to maintain said uprights in their vertical positions of use and enable adjustment of the transverse perpendicularity of said uprights and the respective said surface supported thereby, and
- respective upper and lower transverse connecting members which interconnect the upper and lower parts of respective said uprights facing each other across said cavity, said transverse connecting members enabling adjustment of the spacing between said upper and lower parts of said uprights, whereby the perpendicularity of said surface supported by said uprights in the other said row is adjustable to ensure said surfaces are parallel,
- the improvements wherein:
- a plurality of fixing means are spaced along each upright on it side which, in use, faces said casting cavity;
- coupling elements are provided for fastening to said fixing means;
- stringers are engageable with at least two said coupling elements fixed at substantially the same level in respective said fixing means on adjacent said uprights, in such a way that a flat side of said stringer faces said casting cavity and defines a vertical plane with said flat sides of neighbouring stringers, each said stringer at least partially comprising a soft material which forms an exposed face of said stringer;
- fastening means are driven into and retained by said soft material of said stringers to fasten said panels to said flat side of said stringers, and
- said panels are elongate with arbitrary widths, and are fastened to said stringers side-by-side.

In a method of assembling a shuttering system for casting a concrete wall or partition, comprising the steps of:
- arranging metal uprights to oppose each other in two rows;
- interconnecting upper and lower parts of each opposing pair of said uprights by means of respective upper and lower transverse connecting members which permit the spacing between said upper and lower parts to be adjusted;
- attaching panels to said uprights of each row so that said panels are adjacent each other and define, between said rows, respective flat opposing surfaces delimiting a casting cavity for said concrete;
- adjusting the transverse perpendicularity of one said row of uprights so as to adjust the perpendicularity of said surface supported thereby, and
- adjusting the spacing between said upper and lower parts of said uprights to adjust the perpendicularity of said surface supported by said other row of uprights, to ensure said surfaces are parallel,
- an improvement wherein:
- stringers are attached at different levels to the sides of said uprights facing said cavity when said adjustments of said rows of uprights have been effected, so that each of said stringer interconnects at least two adjacent said uprights in a respective said row, and so that a flat side of said stringer faces said casting cavity and defines a vertical plane with said flat sides of neighbouring stringers, each said stringer at least partially comprising a soft material which forms an exposed face of said stringer, and
- said panels are fastened side-by-side to said flat sides of said stringers with fastening means driven into said exposed faces, said panels being elongate with arbitrary widths.
