[Problems to be solved by the invention]
However, in such a deck material, it is necessary to use a mounting hardware to fix it to the locked member. In addition, if an expensive mounting hardware is used, There is a problem that the cost cannot be reduced sufficiently.
Therefore, as a method of fixing the deck material that can solve such a problem, it is conceivable to directly drive a nail or a screw from above the upper plate portion and fix it to the locked member.
However, it is empirically known that in this method, there is a high possibility that a nail or a screw will punch out the upper plate portion.
Therefore, in order to prevent punching of the upper plate portion of the nail or screw, it is conceivable to reinforce by thickening the entire upper plate portion or at least reducing the interval between the wall portions around the fixing portion of the nail or screw. .
However, even with these methods, since it is necessary to add a member for reinforcing a nail or a screw, the problem that the material cost cannot be sufficiently reduced still remains. In addition, in the method of reducing the interval between the wall portions around the fixed portion of the nail or screw, the area of the cross section perpendicular to the extrusion direction formed by the upper plate portion, the lower plate portion, and the wall portion is locally unevenly distributed. In other words, the speed of extrusion molding is slowed by that amount in order to adjust the balance in material supply when performing extrusion molding.
Accordingly, an object of the present invention is to provide a deck material that can save material while avoiding the inconvenience of punching an upper plate portion by a nail or a screw, and that does not slow down the extrusion molding speed.
