摘要：A prestressed plate-shaped building component (10) comprises a plurality ofelongate laminations (11) of wood, placed in side-by-side relationship and held in contactunder pressure with each other in an elastically compressed state by a plurality ofmutually spaced transverse tension bars (12) of metal, which extend each through onerow of through holes (13) in the laminations (11) and which, at their ends, are providedwith anchoring means (14), projecting in lateral directions therefrom and bearing underpressure against cooperating bearing surfaces (15) of the two outer laminations (11),provided at the outer sides of said laminations. The anchoring means are formed bymetal plates (14), welded to the tension bars (12) at the ends of said bars.
