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.

Abstract: A cribwall comprising(A) a skeletal wall structure made up of components such that there is(i) a plurality of tiers of headers each substantially normal to the general plane of the wall, each header having front and rear end rebates top and bottom, and with each header of one tier being above and/or below a header of an adjacent header,(ii) wall wise extending stretchers each of which spans at least two headers of a tier and the corresponding at least two headers of an adjacent tier and is located between the tiers by the said front end top and bottom rebates of the proximate headers,(iii) rear end header spacing means selected from wall-wise extending stretchers or keyblocks which are interposed between each pair of adjacent tiered headers and are located by said rear top and bottom rebates thereof, and(iv) header support blocks interposed between at least some of the tiered headers between a stretcher and the rear end header spacing means so as to enhance the load carrying capability of the resultant struct

Abstract: An acoustic barrier comprises a free standing wall structure having an exoskeletal framework of gravity interlocked components (preferably of timber) and a filling of the exoskeletal framework. Ideally the structure is tiered and is of substantially constant cross section in each tier, although provision is made to step it up or down to take account changes in the contour on which it is located.
