The invention concerns a method for production of reinforcement chairs in concrete for use in steel-armoured concrete structures, wherein the reinforcement chairs are cast in a mould (9) of a material which is elastic, preferably a two-component rubber mass, and that after hardening the reinforcement chairs are removed by elastically bending the mould's wall parts (11). The invention also concerns a mould for use in production of reinforcement chairs wherein the mould has walls adapted to the shape of the reinforcement chairs, which are made of an elastic material, especially a two-component rubber mass, and that a releasable metal rod (10) is provided perpendicularly through the mould's wall parts, for production of through-going mounting holes in the reinforcement chair. |
