And a suction cup removably fixed to the main body.
[0016]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
First, a double floor structure is shown in FIG.
Reference numeral 1 denotes a room of a building, which is surrounded by a base floor 1a, a wall 1b, and a ceiling 1c. An upper floor 2 is provided on the base floor 1a via a number of support legs (not shown), and a plurality of devices 3 are installed on the upper floor 2.
[0017]
When installing each device 3, the number of mounts 4 is prepared in advance, and these mounts 4 are fixed to predetermined positions on the upper floor surface 2 by, for example, bolting, and the devices 3 are mounted thereon. Various types such as a movable type with wheels are prepared for the gantry 4.
[0018]
An internal space 5 is secured below the upper floor 2, and an electric cable (not shown) of each device 3 is accommodated therein.
The upper floor surface 2 is formed by an array of a large number of panels (panel main body 11 described later), and since each panel can be freely attached and detached as needed at the time of maintenance and inspection, it is generally called a free access floor. Is done. Hereinafter, the upper floor 2 is referred to as a free access floor 2.
[0019]
The air conditioner 6 is installed on the free access floor 2. The air conditioner 6 sucks the air in the room 1 from the upper intake port 6a to cool it, and sends out the cooled air from the lower outlet port 6b as cooling air. The electric cables and pipes of the air conditioner 6 are also housed in the internal space 5.
[0020]
On the free access floor 2, ventilation holes 2 a are respectively formed at locations where the devices 3 are installed and where the air conditioner 6 is installed. The cooling air sent from the air conditioner 6 flows into the internal space 5 through the ventilation port 2a, and flows from the internal space 5 to each device 3 (each gantry 4) through each ventilation port 2a.
[0021]
Each mount 4 has a vent 4a on the lower surface and a vent 4b on the upper surface. Each device 3 has a vent 3a on the lower surface of the housing, a vent 3b on the upper surface of the housing, and a fan 3f inside the vent 3b. The fan 3f operates during operation of the device 3 to form a ventilation path from the ventilation port 3a to the ventilation port 3b.
[0022]
Therefore, when the air conditioner 6 is operated, the cooling air sent from the air conditioner 6 flows into the internal space 5 through the vent 2a of the free access floor 2. The cooling air that has flowed into the internal space 5 receives the blast pressure of the air conditioner 6 and the suction pressure of the fan 3f, flows into the gantry 4 from the vent 2a on the floor surface, and flows into the housing of the device 3. The cooling air that has flowed into the housing of the device 3 is released into the room 1 after cooling the heat source in the housing. The released air is sucked into the air conditioner 6 and becomes the cooling air again.
[0023]
In such a double floor structure, the free access floor 2 is formed by the arrangement of the panel main bodies 11 shown in FIG.
A large number of panel bodies 11 are provided, each having an opening 12 for ventilation and member insertion, and one having no opening 12. Among these panel bodies 11, the panel bodies 11 are arranged such that the panel body 11 having the opening 12 corresponds to the installation position of each device 3 and the air conditioner 6. That is, the opening 12 functions as the ventilation port 2a.
[0024]
Then, as shown in FIG. 1, a plate-like body composed of a plurality of panel pieces 21 is placed at a position corresponding to the opening 12 of each panel body 11, and an arbitrary area of the opening 12 is closed by the placement. Is done.
[0025]
In the opening 12, a region not closed by each panel piece 21 serves as an insertion hole for supplying air-conditioning air to the device 3 and for inserting a member such as an electric cable 31 of the device 3 or a pipe of the air conditioner 6. Used.
[0026]
As shown in FIG. 3, each panel piece 21 is square and has a convex portion 21 a and a concave portion 21 b which can be freely joined and separated from each other at four edges.
The protruding portion 21a protrudes from the peripheral edge so as to expand in a trapezoidal shape. The concave portion 21b is concave so as to expand in a trapezoidal shape from the periphery to the inside, and receives the convex portion 21a of the other panel piece 21 exactly in dimension and securely engages with the convex portion 21a. It is made in size. This engaging action exerts a sufficient holding force so as not to be broken by the weight of each panel piece 21 or the wind pressure of the air for air conditioning.
[0027]
By connecting the panel pieces 21 to an arbitrary size and shape by the mutual engagement of the convex portions 21a and the concave portions 21b, the area and the shape of the closed area with respect to the opening 12 can be freely adjusted.
[0028]
That is, while taking into consideration the amount of heat generated by the equipment 3 to be installed, the insertion state of the electric cable 31 of the equipment 3 and the piping of the air conditioner 6, and the ventilation state of the internal space 5 (the electric cable 31 and the piping The panel pieces 21 are connected to each other in an appropriate size and shape while taking into consideration the ventilation resistance due to the degree of congestion, and the panel pieces 21 are placed in the openings 12. Thereby, the ventilation amount of the opening 12 can be easily adjusted to an optimum state for cooling the device 3.
[0029]
As shown in FIGS. 4 and 5, fixing means, for example, a rubber suction cup 22 is attached to the four corners of the lower surface of each panel piece 21 (the surface on the side corresponding to the panel body 11). FIG. 4 is a view of the panel piece 21 viewed from the lower surface side, and FIG. 5 is a view of the panel piece 21 viewed from the side.
[0030]
As shown in FIG. 6, each suction cup 22 functions to adsorb to the panel main body 11 by being pressed from the upper surface side of the panel piece 21, and to function to detachably fix the panel piece 21 to the panel main body 11. Even if the air pressure of the air-conditioning air passing through the opening 12 is applied to each panel piece 21 or the maintenance staff touches each panel piece 21 by mistake, the suction action of the suction cup 22 and the above-mentioned convex part 21a and concave part 21b are obtained. Of the panel pieces 21 is prevented from collapsing or scattering.
[0031]
The suction cups 22 may be attached to all the panel pieces 21 or may be attached to a predetermined number of the panel pieces 21 that will be located around the opening 12.
Therefore, it is not necessary to prepare various types of ventilation panels as in the related art, and it is not necessary to manufacture ventilation panels that meet the conditions, and it is possible to easily insert members such as the electric cable 31 and piping. Moreover, the cooling action for each device 3 on the double floor can always be set to an optimum state without being affected by the wind pressure of the air conditioning air. Thereby, each device 3 can be operated safely and stably, and furthermore, power consumption is reduced and the operating cost can be reduced.
[0032]
When the electric cable 31 and the pipe have already passed through the opening 12 of the panel main body 21, the respective panel main bodies 21 can be freely joined so as to surround the electric cable 31 and the pipe. By this free joining, it is possible to easily adjust the ventilation amount without moving the installed air conditioner 6, the electric cable 31, the piping, and the like.
[0033]
When adjusting the position of the electric cable 31 or the piping or replacing the panel body 11, the panel pieces 21 placed on the opening 12 are immediately removed, and necessary operations such as adjustment and replacement are performed. Can be done quickly. At this time, the removed panel pieces 21 can be separated and used again by connecting them. Each panel piece 21 can be utilized without waste.
[0034]
In the above embodiment, trapezoidal convex portions 21a and concave portions 21b are employed as means for connecting the panel pieces 21 in a separable manner, but the shape of the convex portions 21a and concave portions 21b is adopted. There is no limitation on itself, and other forms may be used as long as the same function is exhibited.
[0035]
In the above embodiment, the rubber suction cup 22 is used as the fixing means for fixing the panel piece 21 to the panel main body 11, but other means may be used as long as they exhibit a detachable fixing function. Good. The air pressure for air-conditioning does not impair the fixing function, and the maintenance function does not impair the fixing function if touched by mistake, and can be removed only by applying a certain level of artificial action, for example, The use of adhesives is possible.
[0036]
In the above embodiment, the case where the gantry 4 is installed on the free access floor 2 and the equipment 3 is mounted on the gantry 4 has been described as an example. However, the equipment 3 is moved to the free access floor 2 without using the gantry 4. The same applies to the case of direct installation.
In addition, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the invention.
[0037]
