Structural member |
摘要 |
A structural member formed from a billet, each member comprising a plurality of elongate corrugated paperboard sheets bonded together with an adhesive and disposed between a top and a bottom cap, each cap comprising at least one ply of a fiberboard sheet, a pair of side caps of a solid fiberboard sheet bonded to respective side faces of the paperboard sheet and to the respective edges of the top and bottom caps. The billet comprises a plurality of structural members each separated by a corrugated paperboard rip-out sheet. A method of manufacture is disclosed in which the billet is built up of structural members and rip-out sheets. The billet is then ripped into planks which are ripped along the rip-out sheets to separate the structural members for use as a substitute member for wood cleats or members.
