Abstract

See full text

A positioning and fastening system for combining planks comprises at least two planks, each of which has a junction surface at one end plane and a clamping surface at the other end plane wherein the junction surface on each of the planks is designed to have a positioning counterbored hole, the clamping surface is designed to have a pre-burying counterbored hole opposite to the positioning counterbored hole, and both the positioning counterbored hole and the pre-burying counterbored hole allow a bolt hole to penetrate in between. For combining the two planks based on the opposite junction surfaces, the two positioning counterbored holes allow a positioning pin to be plugged in and between for positioning, the positioning pin develops a bolt passage centrally, the nut hole inside each positioning counterbored hole of the two planks pre-buried a nut in which a screw hole is prepared centrally, and a junction bolt penetrates from one nut at anyone of the two planks through the bolt passage and is fixed in the screw hole of the nut at the other plank. Based on above components, combining two planks is completed fastly and accurately.
