Description

[0001]
BACKGROUND OF THE INVENTION
The present invention divides an underfloor space of a free access floor formed by laying a floor panel in a bridging manner over support legs that are regularly erected on a foundation floor surface between the support legs and the support legs. The present invention relates to a partition structure of an underfloor space in a free access floor that is partitioned by installing a board.
[0002]
[Prior art]
Conventionally, there has been a technical idea of using the underfloor space of the free access floor as an air chamber for air conditioning. However, the technology for partitioning the underfloor space of the free access floor with a partition plate is used for anything. There was no thought.
[0003]
[Problems to be solved by the invention]
The present invention has been made in view of the above-described conventional situation, and can easily partition the underfloor space of the free access floor with a partition plate with a certain degree of airtightness, as an air chamber or air duct for air conditioning. In addition, the present invention intends to provide an underfloor space partition structure on a free access floor that can also be used as an underfloor storage.
[0004]
[Means for Solving the Problems]
The partition structure of the underfloor space in the free access floor of the present invention that achieves such an object is a floor under the free access floor configured by laying a floor panel over support legs that are regularly erected on the foundation floor surface. The space is divided by installing a partition plate between the support legs, the upper part of the partition plate is fixed to the panel mounting base of the support leg, and the lower part of the partition plate is It is characterized by being fixed to an L-shaped angle member fixedly installed on the base floor or the base plate of the support leg.
At this time, it is preferable that a plate support is attached to the L-shaped angle member so that the height can be adjusted, and the lower portion of the partition plate is fixed to the plate support.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to the illustrated embodiments.
In the figure, 1 is a support leg regularly standing on the foundation floor 2, 3 is a floor panel laid in a bridge between adjacent support legs 1 and 1, and 4 is an adjacent support. The partition plates installed between the legs 1 and the support legs 1 are respectively shown, and an underfloor space 5 is formed between the foundation floor surface 2 and the lower surface of the floor panel 3.
[0006]
The support leg 1 is installed on a base plate 1a that is bonded and fixed on the base floor surface 2, a leg column 1b that is vertically installed on the base plate 1a, and an upper end of the leg column 1b that is vertically movable. A height adjusting nut for supporting the panel mounting base 1c by screwing with a panel mounting base 1c for mounting and fixing the four corners of the floor panel 3 and a male screw 1d formed on the outer peripheral surface of the leg support 1b. 1e, and the height of the panel mounting base 1c, that is, the height of the support leg 1 can be adjusted by screwing the height adjusting nut 1e.
[0007]
The partition plate 4 is made of a thin metal plate such as stainless steel or aluminum, or a synthetic resin plate, and has, for example, a width substantially the same as the distance between the adjacent support legs 1 and the support legs 1 from the lower surface of the floor panel 3. It is formed in a rectangular shape having a vertical width slightly shorter than the distance to the base floor surface 2, and its upper part (upper side) 4 a protrudes on the four sides of the panel mounting base 1 c of the support leg 1, specifically the panel mounting base 1 c. The formed plate mounting portion 1f is fixed with screws 7, and the lower (lower side) 4b is fixed to the base floor surface 2 or the base plate 1a of the support leg 1 with an adhesive or the like and screwed to an L-shaped angle member 8 installed. Secure it with etc.
In addition, 4c in the figure shows a stop screw for connecting the partition plates 4 to each other.
[0008]
Here, when the lower part (lower side) 4b of the partition plate 4 is fixed to the L-shaped angle member 8, it may be directly fixed to the L-shaped angle member 8 with a screw or the like. A plate support 9 is attached to the L-shaped angle member 8 so that the height can be adjusted so that the height difference and the unevenness of the foundation floor 2 can be accommodated, and the lower part of the partition plate 4 ( The lower side 4b is preferably fixed.
[0009]
There are various possible structures for the plate support 9, but in the illustrated embodiment, a thin metal plate such as stainless steel is used to sandwich the vertical portion 8 a of the L-shaped angle member 8 from above and sandwiching it. In addition, the lower end of the partition plate 4 is formed in a single body with a mounting portion 9b that supports and clamps the lower end from below, and a fastening screw 9c is attached to the clamping portion 9a. The clamping portion 9a is an L-shaped angle member. The plate support 9 is attached to the L-shaped angle member 8 so that the height thereof can be adjusted by engaging with the vertical portion 8a of the plate 8 in a vertically movable manner and fastening with a fastening screw 9c.
[0010]
When airtightness of the space partitioned by the partition plate 4 is particularly required, as shown in the illustrated embodiment, the space between the upper end of the partition plate 4 and the lower surface of the floor panel 3 or the lower end and the plate of the partition plate 4 is used. A seal material 10 having flexible elasticity is interposed between the support portion 9b of the support 9 and the L-shaped angle material 8 and the base plate 1a of the support leg 1 have a length equal to or longer than the lateral width of the partition plate 4. Form on a scale.
[0011]
Thus, when the partition plate 4 is installed in the underfloor space 5 of the free access floor, the height (upper side) 4a of the partition plate 4 is placed on the panel of the support leg 1 after adjusting the height of the support leg 1. The plate support 9 attached to the plate mounting portion 1f protruding from the base 1c with screws 7 is suspended in a suspended manner, and then the plate support 9 attached to the L-shaped angle member 8 is adjustable in the vertical direction. And the lower part (lower side) of the partition plate 4 is placed and clamped in the mounting part 9b of the plate support 9, and the clamping part 9a of the plate support 9 is fixed to the vertical part 8a of the L-shaped angle member 8 in this state. The plate support 9 is fixed to the L-shaped angle member 8 by fastening with fastening screws 9c.
Finally, floor panels 3 are installed over the support legs 1, and each floor panel 3 is fixed to the panel mounting base 1 c of the support legs 1 with screws 11.
[0012]
【The invention's effect】
According to the partition structure of the underfloor space in the free access floor of the present invention, the upper part of the partition plate is fixed to the panel mounting base of the support leg, and the lower part of the partition plate is fixedly installed on the base floor surface or the base plate of the support leg. Since it is fixed to the L-shaped angle member, the underfloor space of the free access floor can be partitioned easily and with a certain degree of airtightness by a partition plate. Therefore, the underfloor space of the free access floor can be used as an air chamber or air duct for air conditioning or as an underfloor storage.
[0013]
Moreover, according to the partition structure of the underfloor space in the free access floor according to claim 2 of the present invention, the plate support is attached to the L-shaped angle member so that the height can be adjusted, and the lower part of the partition plate is attached to the plate support. Since it is made to adhere, even if the foundation floor is somewhat uneven, it can be absorbed and the lower part (lower side) of the partition plate can be fixed securely and appropriately.
