<p>PROBLEM TO BE SOLVED: To lay a rail for a track bogie on a grating floor in a simple construction work. SOLUTION: Bridges 37 are laid in several rows between grating support columns 16 by inserting them onto pins 16a on the columns 16, in a direction in which the bridges 37 cross a running track. Guide rail components 38 and running rail components 39 are positioned and assembled on the bridges 37 in the several rows through fitting, and floor panels 40 are arranged in two rows on opposite sides of the guide rail components 38 so as to fill the gaps between the rail components 38, 39. The rail components 38, 39 and the floor panels 40 are fixed to the bridges 37 by means of screws 42, 43, 44. The floor panels all have the same size, having their lengths in the direction of the track, which is set to a value which is a natural number (such as two) times as long as the length of one side of the grating. The lengths of the rail components 38, 39 are set to a value which is a natural number times as long as the length of the one side of the grating.</p> |
