Abstract

PURPOSE:To enhance bending strength and prevent the torsion of a horizontal rack by a method in which long (in the direction of fibre) thin plates are set in parallel and single plates shorter than the long thin plate are vertically arranged in the longitudinal direction of the long thin plate between the long thin plates. CONSTITUTION:Single parts 12 in which the direction of fibre is slant to the direction of fibre in a long thin plate 11 are vertically arranged in such a way that the direction of fibre is arranged in a waved form toward the longitudinal direction of the long thin plate 11 whose length is along the direction of fibre. The inclined angle in the direction of fibre in the part 12 is set up so that the bending strength of the the horizontal rack 1 is maximized, and the parts 12 are joined temporarily at the places as shown by marks 18. The plate 11 is lapped and bonded with the part 12 to form the horizontal rack 1. The bending strength of the rack 1 can thus be raised by slantly arranging the direction of fibre in the part 12, and the torsion of the rack 1 can also be prevented by vertically arranging the direction of fibre in a waved form.
