<P>PROBLEM TO BE SOLVED: To provide a wing wall whose thickness dimension can be freely changed. <P>SOLUTION: A square pole-shaped laminate unit 1 is horizontally laminated to a sill 4 in a standing attitude composed of horizontal rails 5a, 5b and vertical bars 6a-6c. The outsides of the sill 4 and laminate units 1 are covered with surface members 10a-10c to form a wing wall 11. The thickness dimension of the wing wall 11 can be freely changed by the laminated number of the laminate units 1. Fixing of the sill 4 and the laminate unit 1 and mutual fixing of the laminate units 1 are performed by engaging dowel holes 2a-2d and 7-9 with dowels 3. Namely, the engagement of the dowel holes 7-9 of the sill 4 with the dowels 3 fitted to a laminated unit 1 and the engagement of the dowels 3 fitted to the laminate unit 1 with the dowel holes 2a-2d provided in other laminate unit 1 strengthen the structure of the wing wall 11. <P>COPYRIGHT: (C)2013,JPO&INPIT |
