Board material structure and combination method of the board material structure

Abstract

A board material structure includes multiple boards and multiple embedded rods. The boards each respectively comprise a protrusion and a groove on their peripheral surfaces. The embedded rods each respectively comprise two side surfaces, wherein one of the two side surfaces is corresponding in shape to the protrusion and the other one of the two side surfaces is corresponding in shape to the groove. Furthermore, a melting point of the board is higher than a melting point of the embedded rod. To construct the board material structure, users can melt the embedded rod to connect and combine two boards. The embedded rods can increase structural rigidness of the board material structure and prevent moisture from permeating into the gaps between the two boards. In addition, the present invention can firmly construct a floor, a cabinet, or a drywall.

What is claimed is: 
     
         1 . A board material structure comprising:
 multiple boards each comprising a top surface, a bottom surface, a peripheral surface connecting the top surface and the bottom surface, a protrusion protruding from the peripheral surface, and a groove recessed into the peripheral surface and corresponding in shape to the protrusion; and   multiple embedded rods each mounted between two adjacent boards of the multiple boards and comprising two side surfaces; wherein one of the two side surfaces is corresponding in shape to the protrusion and the other one of the two side surfaces is corresponding in shape to the groove.   
     
     
         2 . The board material structure as claimed in  claim 1 , wherein each of the multiple boards is rectangular, and the peripheral surface has four side faces; the peripheral surface is formed by connecting the four side faces. 
     
     
         3 . The board material structure as claimed in  claim 2 , wherein the protrusion and the groove are respectively formed on two of the four side faces that are opposite each other. 
     
     
         4 . The board material structure as claimed in  claim 1 , wherein the protrusion is formed on the peripheral surface, and the protrusion longitudinally extends along the peripheral surface; the groove is also formed on the peripheral surface, and the groove longitudinally extends along the peripheral surface. 
     
     
         5 . The board material structure as claimed in  claim 1 , wherein the embedded rod is a U-shaped structure from a cross-sectional side view. 
     
     
         6 . The board material structure as claimed in  claim 1 , wherein a melting point of the board is higher than a melting point of the embedded rod. 
     
     
         7 . The board material structure as claimed in  claim 6 , wherein the board is made of aluminum, tin, and other metals or alloys; the embedded rod is made of plastic material. 
     
     
         8 . A method for constructing the board material structure as claimed in  claim 1  comprising:
 an assembling step: placing the embedded rod between the two adjacent boards; disposing the protrusion of one of the adjacent two boards opposite to the groove of the other one of the two adjacent boards; wherein the side surface of the embedded rod that corresponds in shape to the protrusion is mounted on the protrusion of one of the two adjacent boards, and the other side surface of the embedded rod that corresponds in shape to the groove is mounted on the groove of the other one of the two adjacent boards; 
 a hydraulic pressing step: pressing two sides of the two adjacent boards opposite to the embedded rod to press the two adjacent boards towards each other to engage with the embedded rod tightly; 
 a welding step: melting the embedded rod between the two adjacent boards at high temperature to combine the two adjacent boards closely, continuously pressing the two adjacent boards; wherein excess of the melting embedded rod overflows from interfaces between the two adjacent boards; and 
 a scraping step: removing the excess of the melting embedded rod from the interfaces between the two adjacent boards. 
 
     
     
         9 . The method as claimed in  claim 8 , after the scraping step further comprising:
 a polishing step: polishing and trimming the surfaces of the boards; and   a laminating step: laminating a wooden layer with textures on the polished surfaces of the boards.
