Description

[Detailed description of the invention] [Field of industrial application] This invention is a double floor (generally called a free access floor) installed in a room where heavy equipment such as a computer, telephone exchange, etc. is housed. Regarding the structure of

[Conventional technology]

A double floor is used in the room where computers and other equipment are housed, and wiring and piping are installed under the floor.

As shown in Fig. 2, as a conventional double floor structure, a plurality of columns 2 are erected on a floor surface 1,
There is a structure in which a floor panel 4 divided as appropriate is placed on a seat 3 attached to the pillar 2. However, this structure has the disadvantage of lacking earthquake resistance, and may not be able to withstand large seismic forces caused by mounting equipment during an earthquake, and cases of damage have been reported (Reference: Earthquake-resistant design of non-structural materials) Guidelines and Explanations and Seismic Design and Construction Guidelines, Architectural Institute of Japan, 1985).

Therefore, in consideration of the above-mentioned circumstances, when mounting heavy equipment, the support 2, seat 3, and floor panel 4 at the equipment mounting position are removed and the pedestal 5 is placed on the floor as shown in Figure 3. 1, and this pedestal 5 is used to mount and support the apparatus A to ensure earthquake resistance and also to receive the floor panel 4 around the pedestal.

[Problem that the invention attempts to solve]

However, in such a structure, when changing the arrangement or adding equipment, etc., it is necessary to
Vibration, noise, dust, etc. are likely to occur during the fixing work to the floor surface 1, and the work may be restricted due to the negative impact on existing equipment. There are disadvantages such as the need to relocate piping.

For this reason, there has been a problem in the past that when adding heavy equipment, construction work to ensure the necessary seismic resistance takes time, or is impossible in some cases. Furthermore, when installing the pedestal 5, the existing pillars 2, seats 3, and floor panels 4 are no longer necessary, which is also uneconomical.

This idea was created in view of the above circumstances.
Supports mounting of heavy equipment while ensuring earthquake resistance.
To provide an economical double-floor structure that can be quickly and easily constructed regardless of existing equipment, existing wiring, piping, etc.

[Means for solving problems]

For this purpose, the double floor structure of the present invention is such that a plurality of pedestals with legs are fixed to the floor in a straight line to form a row of trestles, and the rows of trestles are arranged at predetermined intervals. A plurality of racks were arranged in parallel, and a floor panel was spanned between the rows of racks.

[Effect]

As a result, devices can be mounted and supported quickly and easily on a row of pedestals that have been installed in advance, while ensuring earthquake resistance, regardless of existing devices, existing wiring, piping, etc.

Furthermore, since the floor panels are spanned between rows of pedestals, there is no need for supports on which to place the floor panels, making it possible to construct a double floor quickly and economically.

〔Example〕

Hereinafter, a double-bed structure according to an embodiment of the present invention will be described. FIG. 1 is a diagram showing one embodiment thereof.
In the figure, reference numeral 6 denotes a pedestal row formed by arranging an appropriate number of trestles 61 in a continuous straight line, and the plurality of rows are arranged parallel to each other and fixed to the floor surface 1.

Each frame 61 consists of a flat plate 61a and a leg part 61b formed on the lower side thereof.The lower end of the leg part 61b is fixed to the floor 1, and the device A is
can now be installed.

Therefore, a plurality of devices A can be arranged on the gantry row 6 along the arrangement direction thereof. Device A
The upper surface of the part where it is not installed can be used as a floor.

Reference numeral 7 denotes a floor panel that spans between adjacent rows of pedestals 6, and its upper surface is at the same height as the upper surface of the flat plate 61a.

[Effect of idea]

As described above, the present invention has a structure in which rows of pedestals capable of mounting and supporting devices are installed and a floor panel is spanned between adjacent rows of trestles, resulting in the following advantages.

(1) Since the equipment can be installed on a row of pedestals that are fixed to the floor in advance, there is no need for floor fixing work that can easily cause vibrations during equipment installation work, and there is no need to worry about wiring or piping under the double floor. You can proceed with the work, and even if the equipment is in a room where it is in operation, you can change the layout, make changes, etc. while ensuring earthquake resistance.
Alternatively, expansion and the like can be dealt with quickly and easily.

(2) Since the floor panel is stretched between frames, there is no need for a support to place the floor panel on, making it easy to conduct wiring, piping, etc. under the floor, and it is possible to quickly and economically construct a double floor.
