Metallic network elevated floorboard structure

Abstract

Metallic network elevated floorboard structure composed a metallic elevated floorboard, leg members, base seats, wire channels, central cover boards and side cover boards. The metallic elevated floorboard is composed of a plane iron panel having multiple punch holes at equal intervals and a concave iron board having multiple concaves riveted with the plane iron panel. Four corners of the elevated floorboard are formed with bores in which the leg member is fitted. The periphery of the elevated floorboard is formed with a flange having notches in which the side cover board is inlaid.

What is claimed is:  
     
         1 . Metallic network elevated floorboard structure comprising an elevated floorboard, leg members, base seats, wire channels, central cover boards and side cover boards which are assembled with each other, the elevated floorboard being a square body with a certain dimension, a periphery of the elevated floorboard being stepped to form a flange, four corners of the elevated floorboard being formed with bores in which the leg member is fitted, the leg member being composed of a plastic collar, a metal nut, a fastening nut and a thread rod, four side of the base seat being formed with notches in which tenons of wire channels are inlaid, four corners of the base seat being provided with upward projecting hollow cylindrical bosses in which the leg member of the elevated floorboard is inserted, the elevated floorboards being interconnected to define cross grooves in which the central cover boards and side cover boards are locked.  
     
     
         2 . Metallic network elevated floorboard structure as claimed in  claim 1 , wherein the elevated floorboard is composed of a plane iron panel having multiple punch hole bosses at equal intervals and a concave iron board having multiple concaves each having a central through hole, the punch hole boss of the plane iron panel being fitted into the through hole and punched to firmly rivet the concave iron board with the plane iron panel.  
     
     
         3 . Metallic network elevated floorboard structure as claimed in  claim 1 , wherein the bores of the elevated floorboard are hexagonal.  
     
     
         4 . Metallic network elevated floorboard structure as claimed in  claim 1 , wherein the flange of the elevated floorboard is formed with notches at equal intervals.  
     
     
         5 . Metallic network elevated floorboard structure as claimed in  claim 1 , wherein the plastic collar of the leg member is a hexagonal collar corresponding to the bores of the elevated floorboard, a bottom of the plastic collar being formed with a flange.  
     
     
         6 . Metallic network elevated floorboard structure as claimed in  claim 1 , wherein outer circumference of the metal nut of the leg member is formed with a flange and sculptured stripes for inserting into the plastic collar, inner circumference of the metal nut being formed with an inner thread.  
     
     
         7 . Metallic network elevated floorboard structure as claimed in  claim 1 , wherein a C-shaped washer and a fastening nut are fitted on the thread rod of the leg member.  
     
     
         8 . Metallic network elevated floorboard structure as claimed in  claim 7 , wherein an upper end of the thread rod is cut with a split for a hand tool to drive the thread rod.  
     
     
         9 . Metallic network elevated floorboard structure as claimed in  claim 1 , wherein each of four corners of the central cover board is formed with a thread hole, recessed assistant locating plates being formed beside each thread hole for locating on two adjacent sides of a corner of the elevated floorboard.  
     
     
         10 . Metallic network elevated floorboard structure as claimed in  claim 1 , wherein two lateral sides of the side cover board are formed with downward bent arch locating plates and recessed assistant locating plates.  
     
     
         11 . Metallic network elevated floorboard structure as claimed in  claim 10 , wherein the locating plates of the side cover board are right engaged in the notches of the flange of the elevated floorboard.
