Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a floor panel support device with built-in electrical outlets for use on double floors such as raised floors, which allows floor panels to be supported by height adjustment. It is supported horizontally and has built-in electrical outlets, OA information terminals, communication sockets, and other outlets.

[Conventional technology]

When constructing a double floor such as a raised floor, a number of height-adjustable support legs are usually installed on a concrete slab, and the height of each support leg is adjusted to install floor panels. Wiring for electricity, information, communication, etc. is placed in the space formed between the top surface of the slab and the floor panel, and is taken out from the floor surface.

By the way, it is common for slab surfaces to have unevenness of up to about 20 mm, and the supporting legs are required to not only support the floor load but also have the ability to adjust this unevenness. 8th
The figure shows a conventional general floor panel support leg 22, in which the height of the leg part erected on a base plate 24 is adjusted with a screw, and a cushion material 22 is placed on an upper support plate 25.
3, the end of the floor panel 12 can be placed on it. Each support leg 22 is installed at a contact point between four adjacent floor panels 12, and the wiring is connected to an outlet box or the like installed by cutting out the floor panel 12.

Further, Japanese Patent Application Laid-open No. 102962/1983 discloses a device in which an outlet box is provided in advance on a floor panel.

[Problem that the invention seeks to solve]

In the case of the conventional support legs 22 described above, at each floor panel 12 support position, the - support legs 22 support the ends of the floor panel 12, resulting in poor stability, and due to the unevenness of the slab surface, the base plate 24 itself may become unstable. Moreover, it is necessary to arrange a separate outlet box in addition to the support legs 22, which takes time and effort to install. Furthermore, since the height of the legs must be adjusted from the side before laying the floor panel 12, it takes time to adjust the height, and adjustment after the floor panel 12 has been laid must be done by removing the floor panel 12. There is the inconvenience of not being able to do so.

This invention aims to solve the above-mentioned problems.
