Raised floor gratings are used in computer rooms, communication equipment rooms, and electronic parts factories that require precision.
A large number of these are laid out and fixed on joists that are supported on support legs that are set up on a concrete floor surface. At this time, the level of the joist is maintained at approximately the same level using screw adjusters provided on the support legs, but if gratings are laid on top of this, it is inevitable that the heights will vary between the gratings. Conventionally, this difference in floor height has not been adjusted, but it is absolutely necessary to adjust this difference in height in order to improve the livability of a clean room with grating. Adjustment of the raised floor using panel materials is done between the floor surface and the panel, that is, on the underside of the panel, so it can only be adjusted at the time of laying the floor material, and it is not possible to adjust the fine height of the floor surface after the floor material is laid. .

The lower end of 8 comes into contact with the upper surface of the joist 50. Next, when a screwdriver is fitted into the cut groove 46 on the head of the adjustment bolt 38 and screwed in, the height adjustment device 32 is raised. Conversely, when the adjustment bolt 38 is unscrewed, the height adjustment device 32 is lowered. Since the main girder 12 of the grating 10 is supported from below by the locking piece 36, the grating 10 can be moved up and down by rotating the adjustment bolt 38, and the height of the gratings can be easily adjusted. can. As shown in FIG. 5, the grating 10 whose height has been aligned in this way is fitted with an L-shaped fixing bolt 52 inserted into the bolt insertion hole 28 of the fixing plate 30 of the fixing device attachment part 26, and the tip thereof is engaged with the joist 50. The grating 10 is fixed to the joist 50 by tightening with nuts 54. The assembly drawing of the double floor using the grating of this example is as shown in Fig. 6, where 56 is a column, 58 is a connecting beam,
60 is bracing.

As explained above, this invention provides mounting parts at the four corners of the grating, and when the grating is laid on the joists, the height adjustment device is inserted from below the mounting part of the grating to adjust the height between the grating and the joists. An adjustment device is attached to the grating, and after the grating is installed, the difference in height between the gratings can be adjusted by turning the adjustment bolt while visually observing the difference in height between the gratings from above. Therefore, the difference in height of the grating can be adjusted with an extremely simple operation compared to the conventional method of adjusting from the bottom of the panel.
Not only does it have excellent effects in terms of ease of work and precision of the floor surface, but it also has the advantage that the structure of the device is much simpler than conventional ones.
