Description

[Detailed description of the invention] [Purpose of the invention] <Industrial field of application> The present invention relates to a height adjustment device for a floating floor in a double-floor structure, and more specifically, it is used in rooms where electronic computers, office automation equipment, etc. are installed. This relates to a height adjustment device that adjusts (sets) the mounting support height of the floating floor in order to form a space (described later) that corresponds to the purpose between the floating floor (free access floor) and the foundation floor surface. .

In this kind of double floor structure, the space between the floating floor and the foundation floor is mainly connected to underfloor air conditioning, and networks such as signal cables and trunk cables for computers and office automation equipment installed on the floating floor. Because the floor panels are to be installed and supported at a height that creates a space corresponding to each of these uses between them and the foundation floor, it is also necessary to lay them adjacent to each other to form a floating floor. There is.

<Prior Art> Conventionally, the height of this type of floating floor has been adjusted by adjusting the length (height) of the supports of the support fittings that support the floor panels forming the floating floor above the base floor surface. In other words, the height of the floating floor is adjusted by mounting and supporting the floor panel by using several types of supporting metal fittings that are separately (individually) processed and formed (configured) using pillars with lengths that correspond to each of the above-mentioned uses. Was.

Therefore, we process and form (configure) several types of support metal fittings with different lengths for each purpose.
As a result, the processing costs rose, making it extremely uneconomical.

<Problem to be solved by the invention> The problem to be solved by the invention is to create a space corresponding to each of the above-mentioned uses by using a kind of support bracket with the same length for the pillars. It is to form between.

[Structure of the idea]

<Means for solving the problem> The technical means taken by the present invention to solve the problem is to lay floor panels adjacent to the supporting metal fittings arranged in a grid pattern on the foundation floor surface. In a double floor structure forming a floating floor, one or several height adjustment members are fitted and stacked on the support metal fittings, and a floor panel is laid adjacent to the height adjustment member to form a floating floor. It is characterized by forming.

<Function> This invention adjusts the height of the floating floor by the length of the pillar of the support metal fitting, the number of fitted and stacked height adjustment members interposed between the support metal fitting and the floor panel, and the wall thickness of the height adjustment member. A space corresponding to the purpose is created between the floating floor and the foundation floor surface.

<Example> An example of the present invention will be described based on the drawings.
In the figure, A is the concrete foundation floor of the building, B is the floating floor, 1 is the floor panel, 2 is the support fittings, and 3 is the height adjustment member.The support fittings 2 are arranged in a grid pattern on the foundation floor A. One or more height adjustment members 3 are fitted and stacked on the supporting metal fittings 2, and the floor panel 1 is laid adjacent to the height adjustment member 3 to form the foundation floor surface A.
A floating bed B is formed above.

The support fittings 2 hold the floor panel 1, which is rectangular in plane and forms the floating floor B, above the base floor surface A, and the height adjustment member 3
The pillar 2a is cut to a desired length and has screws carved on its outer periphery, the seat plate 2b is integrally fixed to the lower end of the pillar 2a, and the pillar 2a has a screw threaded on the outside. This is a well-known structure consisting of a pedestal 2c and a lock nut 2d which are fitted together, and the pedestal 2c is made of a metal plate having a desired thickness and is formed into a rectangular plane, and height adjustment members 3 are fitted to the four corners of the pedestal 2c. The locking convex portion 4 to be locked is formed in the same body.

The height adjustment member 3 is supported so that the space C formed between the floating floor B and the foundation floor A corresponds to the use of underfloor air conditioning, wiring of network cables such as signal cables, trunk cables, etc. This is to adjust the height of the floating floor B depending on the length of the support 2a of the metal fitting 2.

This height adjustment member 3 is formed in the shape of a spacer using a metal material, hard resin material, etc., and a support metal fitting 2 is provided at the center of the lower surface of the height adjustment member 3.
A recess 3a is formed in the center of the upper surface to fit and lock into the locking protrusions 4 provided at the four corners of the pedestal 2c, and to fit and lock when the height adjustment members 3 are stacked together. Convex portions 3b are formed for fitting and locking, and for fitting and locking the mounting recesses 5 provided in the lower surface of the four corners of the floor panel 1. Incidentally, the circumferential surfaces of the locking convex portion 4, the concave portion 3a, the convex portion 3b, and the mounting concave portion 5 are formed in a tapered shape so that they fit smoothly.

Further, the thickness of the height adjusting member 3 may be formed to an arbitrary thickness, but in the drawing, the thickness of the support metal fitting 2 is
The thickness is approximately 1/4 of the length of the pillar 2a, for example, assuming the length of the pillar 2a is 100 mm, the wall thickness is approximately 25 mm.
The height adjusting member 3 formed to have a thickness of about 100 mL is used.

Next, a method of adjusting the height of the floating floor B using the height adjusting member 3 and the support fitting 2 formed as described above will be explained. First of all, the space C required for wiring network cables such as signal cables and trunk cables is approximately 150mm below the floor, that is, the back side of the floor panel 1.
A space C of approximately 150 mm is required from a to the foundation floor surface A, and for example, the locking position of the support fittings 2, which are erected and arranged in a grid pattern on the foundation floor surface A, to the pillars 2a of the pedestal 2c is located at the foundation floor surface A. If the protrusion height of the mounting portions 1b, which are formed to protrude downward from the four corners of the floor panel 1 at a position (height) of about 75 mm from
One height adjustment member 3 formed to a thickness of mm is placed on the pedestal 2.
c By fitting and locking into the locking projections 4 at the four corners and interposing between the pedestal 2c and the floor panel 1, the height between the floating floor B and the foundation floor surface A is set to 150 mm. A space C can be formed (Fig. 1, Fig. 2). Incidentally, minute height adjustments of the floating floor B due to unevenness of the foundation floor surface A are performed by adjusting the height of the pedestal 2c relative to the support 2a, as is conventionally known.

On the other hand, if the space C required for underfloor air conditioning is approximately 200mm below the floor, three 25mm height adjusting members 3 are fitted onto the locking protrusion 4 of the pedestal 2c locked at the above-mentioned height. It can be formed by fitting and locking and stacking them (Fig. 4).

FIG. 5 shows an embodiment in which fine height adjustment of the floating floor B due to unevenness of the foundation floor surface A is performed by stacking height adjustment members 3 formed in a thin wall shape.

Note that the numbers detailed in the above embodiments are merely examples, and the present invention is not limited thereto.

<Function and Effect> As described above, the present invention creates a foundation floor for a floating floor by fitting and stacking one or several height adjustment members on support metal fittings that are arranged upright in a grid pattern on the foundation floor surface. Since the height with respect to the surface is adjusted, there is no need to separately (individually) process and form (configure) several types of support fittings corresponding to the application as in the past. Therefore, since it is sufficient to process and form (configure) only one kind of support metal fittings having the same length of pillars, the support metal fittings can be provided at low cost.

Thus, the intended purpose can be achieved.
