Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a floor structure generally referred to as an OA floor.

(Prior art and its problems) An OA floor has a space between the floor surface of a concrete slab and a floor panel for passing various types of wiring. As for the floor structure,
Some are known that use a floor panel with legs integrally molded into a thick floor material, and others that support a thick single-plate floor panel with height-adjustable support metal fittings. However, it is not possible to use floor boards such as plywood used in conventional general floor structures, and special thick floor panels must be used, which not only increases costs but also requires the use of electrical outlet boxes. When providing mounting holes such as these in a floor panel, there were drawbacks such as difficulty in machining them.

(Means for Solving the Problems) The present invention proposes a floor structure that can solve the conventional problems as described above. A groove for fitting a floor plate is provided, and both sides of a rectangular floor plate that can cover the frame are fitted into both grooves so as to be freely inserted and removed, thereby forming a floor panel. The structure is raised above the floor using adjustable support metal fittings.

(Embodiment) An embodiment of the present invention will be described below based on the attached illustrative drawings. 1 is a floor panel with a rectangular planar shape, and is attached to a frame 2 made of aluminum or the like so that it can be inserted and removed. It is made up of a floor plate 3. The frame 2 is made up of two wooden side frame members 4 located on both sides along the longitudinal direction, which are integrally connected to each other by connecting members 5 at both ends and at the center position, and the both side frame members 4 include: A groove 6 for fitting a floor plate is formed along the longitudinal direction inside the portion projecting upward from the connecting member 5. The lower surface of this recess s6 is flush with the upper surface of the connecting member 5.

The floorboard 3 is made of commercially available plywood, and is inserted in the longitudinal direction of the frame 2 with its both sides fitted into the grooves 6 to cover the entire upper surface of the frame 2. At this time, so that the upper surface of the floor plate 3 is flush with the upper surface of the frame members 4 on both sides of the frame, cutout steps are preliminarily formed at the upper corners of both sides that fit into the grooves 6, as shown in FIG. It is being processed.

Reference numeral 7 denotes a support fitting in which a support plate 11 is connected to a ground plate 9 fixed on a slab floor surface 8 via a screw shaft 10 so that the height thereof can be adjusted. The supporting metal fittings 7 are installed on the slab floor surface 8 at positions where they can support a portion of each corner of the floor panel 1 arranged in a grid pattern, and all of the supporting metal fittings 7
The heights of the support plates 11 are adjusted so that they are located on the same horizontal plane. Then, the floor panel 1 is placed on this support fitting 7 via the frame 2.

12 is a carpet laid on the floor panel 1 laid as described above. This carpet 12 can also be covered with tiled carpet cut into rectangular shapes.
Any material can be used depending on the place of use.

When installing an outlet box or the like, a mounting hole is formed in the floor plate 3 of the floor panel 1 at a certain position. Various wiring etc. are constructed in a space 13 secured between the floor panel 1 and the slab floor surface 8.

(Operations and effects of the invention) The floor structure of the present invention, which can be implemented as described above, can utilize the space secured under the floor panel to install wiring, etc., and can be used as a so-called OA floor. Although it is a thing,
In particular, according to the configuration of the present invention, the floor panel installed via the height-adjustable support fittings is composed of a frame and a floor plate,
The frame has recessed grooves for fitting the floorboard on both parallel sides, and both sides of the floorboard can be inserted into and removed from the recessed grooves, so even if relatively thin commercially available general-purpose plywood is used as the floorboard, the frame will not fit. Due to the presence of this material, the floor panel as a whole can have sufficient strength.

Moreover, since the floor panel is assembled by inserting the floor plate into the groove of the frame, the floor plate can be stably positioned relative to the frame without fixing the floor plate to the frame, and can be handled in the same way as a one-piece floor panel. It is possible to easily perform the installation work. In addition, when drilling holes for mounting an outlet box, etc. in a floor panel, the processing work can be performed on the floorboard fitted to the frame, but if necessary, the processing may be performed with the floorboard removed from the frame. You can also do some work. Even if a processing error occurs, it is only necessary to replace the floorboard, and there is no need to replace the entire floor panel.

Furthermore, the floorboard can be made of any material depending on the installation location, such as a nonflammable material or a material with a high sound absorption effect.

Claims (1)

[Claims] Concave grooves for floor plate fitting are provided on both parallel sides of a frame having a rectangular planar shape, and both sides of a rectangular floor plate capable of covering the frame are fitted into both concave grooves so as to be freely inserted and removed, thereby forming a floor panel, A floor structure in which this floor panel is lifted off the floor using height-adjustable support fittings that support the frame.
