| (57) 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 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 stretcher 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 of
keys 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 structure, and
(B) fill material at least substantially filling said skeletal wall structure.
The invention also consists in a header for a cribwall including header support blocks,
said header formed in wood of substantially rectangular cross-section and having top
and bottom (i) a lenghtwise extending groove and (ii) rebates adjacent each end that
extend fully across the transverse section.
