Description

Detailed Description of the Invention [Field of Industrial Application] The present invention is a method of constructing a lower floor by laying panels of standard dimensions in a gate shape, and supporting the corner abutting portions of the four panels on the lower floor by support legs. In order to make it easier to use the space under the panel floor, the equipment installed on this floor is installed on the free access floor where the flannel can be freely removed. It relates to a fixing jig for not only simply placing the product on the support leg, but also firmly fixing it to the support leg.

[Conventional technology]

Raised floors like the ones above can keep the floor surface simple by passing power wiring, piping, etc. for the equipment installed above the floor under the panels, and also allow the panels to be removed freely. Therefore, it has the advantage of easy maintenance and inspection of cables, etc., and easy layout changes, and has come to be used in a wide range of applications, such as for electronic computers and clean rooms for IC manufacturing. There is.

Such raised floor panels are simply supported at a fixed height above the lower floor by support legs.
It can be easily removed.

Therefore, in order to stably fix the equipment installed on the panel surface against earthquakes, etc., bury the lower ends of anchor bolts (foundation bolts) in the concrete floor below the panel, and attach the equipment to these bolts. I fixed it.

[Problem that the invention seeks to solve]

In order to secure equipment using the above method, it is necessary to drill holes for anchor bolts in the concrete floor, and this drilling process not only generates dust, vibrations and noise, but also causes the hardening of the concrete. The disadvantage is that it takes time to prepare.

[Means for solving problems]

In order to solve the above problems, the present invention fixes the equipment on the panel to the panel using long bolts, extends the long bolts downward, and provides a channel extending laterally at the end of the extension. It is mounted in a variable mounting position, and the extended end of the channel is fixed firmly with a device to a support leg that supports the spring hull on the lower floor.

〔Example〕

Next, the present invention will be explained by examples.

FIG. 1 is a perspective view for fully explaining an embodiment of the present invention. In the figure, square standard size panels 11 that serve as floorboards are lined up on a flat surface, and the corners of the four panels (only three panels are omitted in the figure) are connected to the concrete floor below. Support leg 1 fixed with fixing pin 13 to
2, it is supported at a constant height from the lower floor. Equipment 10 is installed on a panel 11, and the fixing part of the equipment 10 is fixed to the panel 11 with a nut on a long bolt 1 that passes through the panel 11, and the lower end of the long bolt 1 extending downward is , is fixed to the bent edge of the opening of the channel 2, which is a rectangular tube with an open upper surface, by means of a flat plate 3 and a nut 4, so that the mounting position in the lateral direction can be changed. channel 2
The horizontally extending end is a U-shaped screw 5 that is a fixing fitting.
It is fixed so that it can be read as follows. The positional relationship between the long bolt I and the support leg 12 is adjusted by rotating the channel 2 in the direction of arrow A and moving the mounting position of the channel 2 in the direction B with respect to the long bolt 1. Furthermore, channel 2 can also be moved in the vertical direction.

〔Effect of the invention〕

As explained above, when the fixing jig of the present invention is used when fixing equipment on a raised floor, it is possible to easily fix equipment without generating dust, vibration, or noise. . Since dust generation and vibration cause trouble to precision instruments in clean rooms, the present invention has a great effect in eliminating these troubles.
