ABSTRACT:
A method for making a corner and a corner formed thereby for a crib wall having a setback includes preparing a base for the two walls to provide the required setback of each wall, laying on the base the wall headers and a corner header of the tier, laying on the wall headers and the corner header the required structures and keys and/or header support blocks to complete the first tier, thereafter laying on stretchers and keys and/or header support blocks of the first tier the wall headers and corner header of the second tier above the substantially corresponding components of the first tier, and continuing tiering of the wall, the arrangement being that each corner header includes a stretcher-receiving groove at the top and bottom thereof with respect to the tiering direction in which the ends of stretchers from the two walls can butt, or almost butt, the lower groove of each corner header being closer to the outside of the corner and the upper groove.
