Abstract (en)
[origin: JPH02144459A] PURPOSE: To simplify manufacturing and storage by means of grids of the same form by providing inclined end surfaces on both side walls, and an oblong hole in which tongue pieces or mounting bolts penetrate in the other both side walls, and selectively assembling them with a lower support structure of a raised floor. CONSTITUTION: A raised floor is composed of height-adjustable supports 10, a grid girder 11, and floor plates 12, and two pairs of slits 15 are provided in the form of a cross in a head plate 14 of the support 10. An inclination surface 18 is provided on each side wall of the girder 11 formed of an angular pipe, an oblong hole 21 is provided in an upper side wall 19, and a tongue piece 22 is provided on a lower side wall 20. Next, in connecting the girder 11 to the support 10, the wall 19 or the wall 20 is selectively directed upward, and the surface 18 is inserted into one pair of the slits 15. When the wall 20 is directed upward, the tongue piece 22 is engaged in a hole 16 between the slits 15, and when the wall 19 is directed upward, it is connected by an installation bolt 27. By thus utilizing the girder 11 of the same form, manufacturing and storage of the girder 11 can be easier.
