Abstract
A hollow core sheet having a plurality of channels and at least one bendable reinforcement rod adapted in width and thickness to a given channel dimensions for insertion inside a channel wherein the method of insertion consists in the steps of having the at least one bendable reinforcement rod having either or both of the width or the thickness having an outer dimension (OD) set between 0.50 0.75 of the given dimension of the channel with a variation of 5%.
Claims1
A plastic hollow core sheet comprising:
- a plurality of rectangular uniform channels having a channel length consisting of a top portion and a bottom portion, wherein the top portion and the bottom portion are parallel and the distance between the top portion and the bottom portion defining an internal width;
- a circular reinforcement rod having a rod length and an outer diameter 50%-75% of the internal width, wherein the circular reinforcement rod is inserted within a channel of the plurality of rectangular uniform channels;
- and,
- the circular reinforcement rod is bent at a minimum bend angle within the channel such that the rod length is less than the channel length and the circular reinforcement rod does not conform to a shape of the channel.
