Abstract

PURPOSE:To reduce magnetic troubles by using a magnetic shielding member for a panel constituting a free access floor to magnetically connect the adjacent panels to each other. CONSTITUTION:There are provided a pair of supporting legs 2 installed on a floor 1 at a predetermined interval, a panel 5 made from a magnetic shielding material which also is an elastic material, insertion pieces 5a which are integrally formed on the four sides of the panel 5 so as to be inclined with respect to the sides of the panel. The pieces 5a are inserted into between a pair of the supporting legs 2 against elastic forces of the pieces 5a to be fixed thereto.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic shield structure for a free access floor.

[0002]

2. Description of the Related Art In a free access floor, panels are spread so as to have a predetermined space between the floor and the floor, and OA equipment is provided under the panel.
By laying wiring for telephones, it is possible to freely pull out the wiring from any panel, without exposing the wiring on the floor, and with a method that can easily change the wiring pullout in response to layout changes. is there.

By the way, during construction of buildings, magnetic materials such as steel frames, reinforcing bars and other metals in building structures such as slabs, walls and columns used electric welding and electromagnets during the manufacturing process in factories and construction of buildings. It may be magnetized by the carrier magnetism and exist as residual magnetism when the building is completed. If there is an electric room on the lower floor, a magnetic field may be generated by the current. as a result,
The OA device malfunctions due to the influence of the magnetic environment, the color shift of the CRT display of the computer occurs, the information in it is corrupted, etc., and the reliability of the system deteriorates, which seriously affects the business. . In particular, it is expected that this will become a serious problem as the definition and multicolor of CRT displays progress. To solve this problem,
Although it may be possible to repair the magnetized portion by destroying it, there is a problem in the strength of the building structure, and conventionally, no effective measure for solving this problem has been taken.

The present invention is to solve the above-mentioned problems, and to reduce magnetic interference by using a magnetic shield member for a panel forming a free access floor and magnetically connecting adjacent panels. It is an object of the present invention to provide a magnetic shield structure for a free access floor that enables

[0005]

To this end, the magnetic shield structure for a free access floor according to the present invention is made of a pair of support legs 2 installed on the floor 1 at a predetermined interval and a magnetic shield material and an elastic material. Panel 5 and panel 5
And the insert piece 5a integrally formed so as to incline on four sides of the insert piece 5a between the pair of support legs 2 and the insert piece 5a.
It is characterized by being inserted and fixed against the elastic force of. It should be noted that the numbers added to the above-mentioned configurations are for comparison with the drawings in order to facilitate understanding of the present invention, and the configurations of the present invention are not limited thereby.

[0006]

In the present invention, the panel 5 is mounted as shown in FIG.
As shown in (B), insert the insertion piece 5a of the panel 5 into the support leg 2
It is performed by forcibly inserting the panel 5 against the elastic force of the insertion piece 5a during this period, whereby the adjacent panels 5 can be reliably brought into contact with each other via the insertion piece 5a.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an embodiment of a magnetic shield structure for a free access floor according to the present invention. FIG. 1 (A) is a sectional view after laying a panel, and FIG. 1 (B) is for explaining a panel mounting method. An enlarged sectional view and FIG. 1C are perspective views of the panel.

In FIG. 1 (A), support legs 2 are installed on a floor 1 at a predetermined interval. The support legs 2 are provided on a frame 2a fixed to the floor 1. One support leg 2 is installed at a position facing the wall 3, and a pair of support legs 2 is installed at a position away from the wall 3. The panel 5 is made of a high magnetic permeability material such as a silicon steel plate and is made of an elastic material in order to shield the magnetism of the steel frame (about 2 G gauss) and the magnetic field of the alternating magnetic field (about 200 m Gauss). Four
The insertion piece 5a is integrally formed so as to be inclined to the side.

As shown in FIG. 1 (B), the panel 5 is mounted by inserting the insertion piece 5a of the panel 5 between the support legs 2 or between the wall 3 and the support leg 2 and elastic force of the insertion piece 5a. This is carried out by forcibly inserting and fixing the panels 5 against each other, whereby the adjacent panels 5 can be reliably brought into contact with each other via the insertion pieces 5a, and the electrical and magnetic connections between the panels 5 can be established. Can be planned.

[0010]

As is apparent from the above description, according to the present invention, a magnetic shield member is used for the panel forming the free access floor, and the adjacent panels are magnetically connected to reduce the magnetic interference. Can be made.
