Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of an air-conditioning free access floor in which a space formed between a foundation floor and a floor panel is used as a chamber for supplying air for air-conditioning.

[0002]

2. Description of the Related Art Conventionally, as this type of air-conditioning free access floor, an elastic member is provided on a side surface of the floor panel in order to isolate an underfloor space of the floor panel (a chamber for supplying air for air conditioning) from an upper floor space. A structure in which a sealing material is attached and adjacent floor panels are sealed by compressive deformation between the sealing materials is used (for example, see Japanese Utility Model Laid-Open No. 5-92566).

[0003]

However, the floor panel in the free access floor is often detached after the construction due to the movement of the arrangement of the installation items such as electronic computers installed on the floor, In the case of the above-mentioned sealing structure, there is a problem that it is difficult to maintain the sealing effect for a long period of time, such that the sealing materials are rubbed with each other at the time of desorption and the sealing materials are damaged or come off.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems in the conventional air-conditioning free access floor, and provides a air-conditioning free access floor capable of maintaining a sealing effect for a long period of time. Is the main purpose.

[0005]

In order to solve the above-mentioned problems, the first invention of the present application is to provide a large number of support legs standing on the foundation floor in a base-like pattern, and the floor panel has four support legs at the four corners. In the air-conditioning free access floor where the underfloor space between the floor panel and the foundation floor is used as an air-conditioning air supply chamber, the floor panel is attached to the back surface of the floor panel, The flexible magnetic sheets projecting outward from the respective sides are sealed by the mutual magnetic force close contact action, so that the space above the floor and the space below the floor are separated from each other.

A second aspect of the present invention is that a floor panel having support legs provided at four corners is laid adjacently on a base floor.
In a free-access floor for air conditioning in which an underfloor space between the floor panel and the foundation floor is used as an air-conditioning air supply chamber, a flexible magnetic attached to the back surface of the floor panel and protruding outward from each side of the floor panel. The structure is such that the space above the floor and the space below the floor are isolated by sealing by the mutual magnetic close contact action of the sheets.

The flexible magnetic sheet used in the present invention is
For example, magnetic powders such as barium ferrite and strontium ferrite bonded by a binder such as thermoplastic resin or rubber are preferable. Further, in order to secure sufficient magnetic characteristics, the above-mentioned flexible magnetic sheet should preferably have about 70% of magnet powder, but this causes the amount of binder to decrease, and cracks occur due to repeated bending. there is a possibility. For this reason, it is advantageous to attach a synthetic resin film on one surface to reinforce it and improve durability.

[0008]

In the air-conditioning free access floor of the present invention, when the floor panels are laid side by side, a flexible magnetic sheet attached to the back surface of the adjacent floor panel and protruding outward from each side of the floor panel is provided. By overlapping each other and closely contacting with each other by magnetic force to seal, the gap between the adjacent floor panels is filled, and the underfloor air conditioning and the above floor air conditioning are isolated.

Further, in the air-conditioning free access floor of the present invention, since the flexible magnetic sheets attached to the back surface of the floor panel seal by magnetic attraction, the sealing materials rub against each other when detached. In this case, the sealing material is not damaged, and if the sealing material is firmly fixed to the floor panel with an adhesive or the like, the sealing material will not come off.

Further, in the case where the reinforcing metal plate is attached to the back surface of the floor panel, since it can be adsorbed and held by magnetic force when attaching the flexible sheet, it is not necessary to use an adhesive agent or the like, It is possible to easily attach and detach the flexible magnetic sheet. In this case, the magnetic sheet may come off when the floor panel is bonded,
Recovery work can be performed easily.

1 to 2 show an embodiment of the first invention. In the figure, reference numeral 1 is a floor panel which is laid adjacent to each other and has a dish-shaped reinforcing steel plate 2 on the back surface. A flexible magnetic sheet 3 protruding outward from each side of the floor panel is attracted to and held on the back surface of the floor panel 1 by magnetic force. The floor panel 1 is laid adjacently so that its four corners are supported by the support legs 4 arranged on the foundation floor.

The support leg 4 includes a fixed plate 4a fixed on the foundation floor, a height-adjustable post 4b standing on the fixed plate, and a panel seat 4c attached to the upper end of the post. It is composed of the panel seat 4
The c is provided with a ridge 5 for controlling the position of the floor panel, and a cushion material 6 is attached to the upper surface.

When the floor panels 1 to which the above-mentioned flexible magnetic sheets 3 are attached are laid side by side, the flexible magnetic sheets 3 and 3 attached to the adjacent floor panels 1 as shown in FIG. By overlapping with each other and adhering to each other by magnetic force, a seal portion is formed and the underfloor space and the above-floor space of the floor panel are isolated. Further, in this embodiment, the panel portion supported on the panel seat 4c of the floor panel 1 is sealed by the cushion material 6.

FIG. 3 to FIG. 4 show an embodiment of the second invention. The floor panel 1 in this embodiment is provided with support legs 7 whose heights are adjustable at four corners, and the flexible magnetic sheets 3 and 3 attached to the adjacent floor panel 1 are shown in FIGS. Similar to 2, the seal portions are formed by overlapping each other and adhering to each other by magnetic force, and the underfloor space and the above-floor space of the floor panel are isolated.

[0015]

As described above, according to the air-conditioning free access floor panel of the present invention, the following effects can be obtained.

(1) In the air-conditioning free access floor of the present invention, when the floor panels are laid side by side, they are attached to the back surface of the adjacent floor panels and project outward from each side of the floor panels. The magnetic sheets are overlapped with each other and closely adhered by magnetic force to form a seal portion, thereby filling the gap between the adjacent floor panels.

(2) Since the air-conditioning free access floor of the present invention has a structure in which it is sealed by the flexible magnetic sheet attached to the back surface of the floor panel, a seal member made of an elastic member is attached to the side surface of the floor panel. Unlike the conventional floor structure in which the sealing materials of the adjacent floor panels are compressed and deformed to each other, the sealing materials are not damaged by being rubbed against each other at the time of attachment / detachment. Further, by attaching a synthetic resin film to one surface of the flexible magnetic sheet to reinforce it, the durability of the flexible magnetic sheet can be improved.

(3) When the back surface of the floor panel is made of a steel material, it can be adsorbed and held by magnetic force when attaching the magnetic sheet. The seat can be easily attached and detached. Further, even if the flexible magnetic sheet comes off when the floor panel is bonded, the recovery work can be easily performed.
