PURPOSE:To make a large scale type of suction device unnecessary and to reduce costs by forming such a construction as sucking a polluted air in a room into an air collection pipe through a filter from the upper openings of a plurality of bearing columns to bear a floor panel. CONSTITUTION:A floor panel 5 is born by a plurality of raised floor bearing columns 4 provided with a receiver 18 to bear the floor panel 5, providing a filter 15 to the upper end opening 14a of a cylinder 12 of which the upper end is exposed to the surface of the floor panel 5, providing connection holes 23 connected to an air collection pipe 9 placed on the lower floor 2 to the lower part of the columns 14. A polluted air in a room is uniformly sucked into the air collection pipe 9 through the filter 15 from the surface opening 14a. According to the constitution, a uniform temperature distribution is maintained without flying dusts, a perforated floor board is not required, high strength panel can be used at a low cost and, at the same time, a small scale type of suction device can collect air.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a support column for supporting a floor board in a double floor for an office where wiring and air purification are easy to perform in order to use office automation equipment and the like.

Conventional technology Generally, air in an office is purified by installing an air conditioning outlet in the ceiling and letting it leak outside through a hallway, or by installing an air suction port in the ceiling to collect contaminated air inside the office. . However, such conventional air conditioning equipment has problems such as uneven temperature distribution and the raising of dust. Particularly in factories that manufacture precision parts, porous floorboards such as gratings are installed on the floor. Adopts a double floor using a ceiling supply floor suction system.

Problems that the invention aims to solve However, in offices that use OA equipment that does not require very precise air conditioning, there is a lot of movement of workers, equipment, chairs, etc., and porous floorboards such as gratings make it difficult to walk This may impede the movement of equipment and equipment.
Additionally, perforated floorboards that could withstand the weight of desks, people, and equipment were expensive. Furthermore, in order to uniformly suck indoor air from the entire surface of the floor, the air in the space under the floor must be sucked, which requires a large suction device.

The present invention solves the above-mentioned problems and solves a major problem at low cost.In order to solve the above-mentioned problems, the present invention provides support for floor panels arranged at regular intervals on a subfloor surface. A cylindrical body having a receiver and whose upper end surface is exposed on the upper surface of the floor panel is provided, a filter is provided at the upper end opening of this cylindrical body, and an air recovery pipe arranged on the lower floor surface is connected to the bottom of the cylindrical body. A connection hole is provided for connection.

Effect In the above configuration, indoor contaminated air is uniformly sucked into the air recovery pipe through the filter from the upper openings of the plurality of support pillars that support the floor panel, so the airflow formed indoors kicks up dust. Contaminated air can be collected uniformly and a uniform temperature distribution can be maintained. Furthermore, since there is no need to use a porous floorboard, there is no hindrance to walking or moving equipment, and a high-strength floor panel can be used at low cost. Furthermore, since indoor air is sucked through the air recovery pipe, air can be recovered using a small suction device.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 to 3.

As shown in FIGS. 2 and 3, this office 1 is formed into a double floor by a floor panel 5 supported by a plurality of support pillars 4 with a space 3 formed on a lower floor surface 2. A ceiling cassette 7 is installed on the ceiling 6 and is connected to an air purifier (not shown) to supply clean air into the office 1. A plurality of air recovery pipes 9 connected to a return duct 8 are provided. This return duct 8 is connected to an air cleaner or exhausted to the outside by an exhaust device (not shown).

The floor panel 5 consists of a plurality of square panel plates 5a,
As shown in FIG. 1, the support column 4 that supports the four corners of the panel board 5a has a cylindrical body 12 erected on a seat plate 11, and a flange 13 is locally provided at the upper end of the cylindrical body 12.
is formed, and the air suction passage 1 in the cylindrical body 12 is formed.
4 is opened in the opening 14a.

Further, a hexagonal screw 16 with a filter 15 is screwed into a female threaded portion 14b formed in an opening 14a at the upper end of the cylindrical body 12, and a male threaded portion 1 formed at the outer periphery of the cylindrical body 12
A receiver 18 for supporting the floor panel 5 is screwed into the member 7 . This receiver 18 has a female threaded part 19 formed on its inner circumferential surface to be screwed into the male threaded part 17, and a body part 21 having a rotating hexagonal flange 20 formed at its lower end.
The panel plate 5 of the floor panel 5 is provided protruding around the upper end of the panel 1.
It consists of a flange-shaped receiving plate 22 that supports the four corners of a,
The receiving plate 22 and the flange 13 of the cylindrical body 12 are configured to sandwich the four corners of the seven-panel plate 5a. Further, a connecting hole 23 communicating with the air suction channel 14 is formed in the lower part of the cylindrical body 12, and a flexible pipe 24 connected to the air recovery pipe 9 is connected to this connecting hole 23.

According to the above configuration, clean air is supplied into the office 1 from the ceiling cassette 7, and contaminated air such as cigarette smoke is passed through the filter 15 from the openings 14a at the upper ends of the support columns 4 arranged at the four corners of the panel board 5a. Air blowing channel 14 of cylindrical body 12
from the connecting hole 23 to the flexible pipe 24.
, is recovered into the return duct 8 via the air recovery pipe 9. Therefore, unlike conventional air conditioning equipment, there is no dust being stirred up or temperature unevenness occurs, and the panel board 5a, which does not have any pores, can be used, so it does not interfere with walking, and it is inexpensive and has high strength. It will be done. Furthermore, since the contaminated air is also sucked in by the air recovery pipe 9, a large suction device is not required, and the suction can be carried out using only the negative pressure of the return duct 8.

FIG. 4 shows an office 31 according to another embodiment, in which an air purifier 33 to which an air recovery pipe 32 is connected is provided in the office 31, and the ceiling cassette is omitted.

FIG. 5 shows an office 41 that is a combination of the above embodiments/another embodiment, in which an air recovery pipe 42 is connected to a fan coil unit 43 in the perimeter zone, and clean air is supplied from a ceiling cassette 44. , the air inside the office 41 is circulated to improve the air conditioning effect.

FIG. 6 shows an office 51 according to yet another embodiment, in which an air conditioning tower 52 with an air handling unit built inside is installed in place of the ceiling cassette 44 and fan coil unit 43 of the embodiment shown in FIG. An air recovery pipe 53 is connected to this air conditioning tower 52 to enhance the air conditioning effect and improve the aesthetic appearance.

Effects of the Invention As described above, according to the present invention, indoor contaminated air is sucked into the air recovery pipe through the filter from the upper surface openings of the plurality of support columns supporting the floor panel, so that the air flow formed indoors is reduced. polluted air can be collected uniformly without raising dust, and a uniform temperature distribution can be maintained.

Furthermore, since there is no need to use a porous floorboard, there is no hindrance to walking or moving equipment, and a high-strength floor panel can be used at low cost. Furthermore, since indoor air is sucked through the air recovery pipe, air can be recovered using a small suction device.
