Description

Description: TECHNICAL FIELD The present invention relates to a floor panel support device that supports a plurality of floor panels on a reference floor surface by support legs.

(Prior art) A double floor with a large number of floor panels laid above a standard floor surface such as a concrete floor and a free space where cables and ventilation ducts can be placed between the floor panel and the standard floor surface. The structure, the free access floor, is known.

Among the free access floors, for the raised floor type,
Independent support legs that are separate from the floor panel are used. In addition, the floor of buildings such as buildings is not necessarily formed in a uniform plane, and there are uneven parts and sloped parts.Therefore, the height adjustment part and the upper part of the column base are loosely fitted to the support legs. A part is provided so that the floor panel can be laid horizontally.

(Problems to be solved by the invention) However, in the construction of the free access floor,
The base portion 9b of the support leg 9 and the column base 9a are integrally formed, and even if the base portion 9b is arranged in a blackened regular position, the reference floor surface 3 has an uneven portion or an inclination. If there is a part, the base part 9b
Since the column base 9a cannot be mounted horizontally, the column base 9a is inclined and the upper end portion is displaced from a predetermined position, so that the floor panel cannot be properly supported. Therefore, after temporarily fixing the base portion 9b to the blackened position, it was necessary to shift the position again while adjusting the stringer 20 (see FIG. 7).

Therefore, an object of the present invention is to provide a floor panel support device capable of forming a predetermined floor panel support frame regardless of the unevenness and inclination of the reference floor surface.

(Means for Solving the Problems) In order to achieve the above object, a floor panel support device of the present invention comprises a plurality of support legs standing on a reference floor surface, and the reference legs are provided by the support legs of the plurality of floor panels. In a floor panel support device, which is supported above a floor surface and fixes the floor panel to the support leg by a panel retainer that is tightened to the upper ends of the support legs, the support leg is a base fixed to the reference floor surface. It has a pedestal part and a cylindrical column base that is erected on the pedestal part, and a threaded part is provided on the pedestal part, and a height adjustment nut is screwed onto the threaded part, On the outer peripheral surface of the adjusting nut, a tapered cone-shaped column base loose fitting portion that reduces in diameter upward and a flange located at the lower end of the column base loose fitting portion are formed, and the lower end portion of the column base is By loosely fitting the column base loosely fitting portion and by the flange The floor panel is supported and fixed to the column base by fastening the panel retainer to the column base.

(Operation) In the floor panel support device of the present invention having such a configuration, since the column base is engaged with the height adjusting nut having a tapered cone shape that is reduced in diameter upward, in a loose fit state,
Even if the base part is inclined, the column base can be erected vertically. Therefore, when the floor panel is fixed to the upper ends of the support legs by the panel presser in this state, a rigid rigid frame structure is constructed by the two adjacent support legs and one side edge of the floor panel between these support legs. A double floor with extremely high rigidity can be constructed. In addition, since the height adjustment nut that supports the lower end of the column base is located near the base by screwing it into the threaded portion, even if a horizontal load acts on the floor panel that constitutes the double floor, A large moment that tries to separate the base unit from the reference floor does not act on the base unit. Therefore, it is possible to reduce the size of the base portion, and in addition to the fact that the column base is maintained vertically in place during the construction of the free access floor, the construction of the free access floor is facilitated.

Embodiments Embodiments of the present invention will be described below with reference to the drawings.

1 to 5 show an embodiment of the present invention. The free access floor 1 is constructed by laying a plurality of floor panels 2 on a reference floor surface 3 such as a concrete floor so as to be supported by support legs 4.

The supporting legs 4 are provided at the corners 2 of the four floor panels 2 adjacent to each other in the center of the free access floor 1.
a is arranged below a position where four corners 2a of two floor panels 2 adjacent to each other are arranged below the position where two corners 2a of the floor panel 2 are gathered together. .

As shown in FIGS. 2 to 4, the support leg 4 has a screw portion 10 provided upright at the center of the upper surface of the base 5 and a flange 11b for receiving the lower end of the column base 7 on the outer peripheral surface. The adjusting nut 11 described above is screwed together, and a cylindrical column base 7 having a stringer pedestal 8 at the upper end is erected upright via the adjusting nut 11. Here, the column base loose fitting portion 11a of the adjusting nut 11 is formed in a tapered cone shape whose diameter is reduced upward (see FIG. 3). In addition, the height of the support leg 4 is adjusted by loosening the tightening member 12 formed of bolts and nuts fixed to the lower end of the column base 7 and rotating the adjustment nut 11 to rotate the adjustment nut 11. It is carried out by moving vertically with respect to 10.

The stringers 20 are arranged so as to extend along the peripheral edges of the floor panel 2, and the ends of the stringers 20 are the stringer cradle 8 at the upper end of the column base 7 and the bottom and side surfaces of the stringer cradle 8. They are fitted with concavities and convexities. Therefore, the stringer 20 forms a right angle with the column base 7, and also keeps the interval between the adjacent column bases 7 constant.

At this time, the column base 7 is engaged with the height adjusting nut 11 screwed into the screw portion 10 of the base portion 5 in a loosely fitted state. Even if part 5 is tilted,
The column base 7, which is engaged with the stringer 20 which is kept horizontal, is erected vertically (see FIG. 4). Therefore, it is not necessary to adjust the base 5 and the column base 7, and the construction of the free access floor 1 becomes easy.

Here, an example of the construction procedure of the free access floor 1 is as follows (see FIG. 6).

A floor allocation reference line 32 is marked on the reference floor surface 3.

The base portions 5 are adhesively fixed to the marked positions.

Two threads are made orthogonal to the finished surface height of the floor panel 2 to set the construction reference line 31.

The supporting leg 4 serving as a reference is erected on the orthogonal portion of the construction reference line 31.

i) The column base 7 is erected on the height adjusting nut 11 of the base 5.

ii) Install the stringer 20 between the upper ends of the column bases 7,
Form a floor panel support frame.

iii) The floor panel 2 is placed, and two sides of it are the construction reference line 3
The height of the support leg 4 is adjusted so as to coincide with 1, and the column base 7 and the height adjustment nut 11 are fixed.

Similarly, the column base 7 is erected on the adjacent base portion 5, and
The stringer 20 is installed between the upper ends.

The floor panel 2 is placed and tightened and fixed by the panel retainer 15 to form the free access floor 1.

At this time, the floor panel supporting surface is kept horizontal and is formed in an accurate square shape. Therefore, the column base 7 is arranged at a fixed position and perpendicular to the base 5, so that the workability of the free access floor 1 is improved.

(Effect of the Invention) According to the floor panel support device of the present invention having such a configuration, the column base is engaged with the height adjusting nut having a tapered cone shape whose diameter decreases upward in a loosely fitted state. Therefore, the column base can be vertically erected even if the base is inclined. Therefore, if the floor panel is fixed to the upper end of the support leg by the panel presser in this state, the adjacent two
A rigid rigid frame structure is constructed by the supporting legs of the book and one side edge of the floor panel between the supporting legs, so that a double floor with extremely high rigidity can be constructed. Also,
Since the height adjustment nut that supports the lower end of the column base is located near the base part by being screwed into the screw part, even if a horizontal load acts on the floor panel that constitutes the double floor, the base part A large moment that tries to separate the part from the reference floor does not act on the base part. Therefore, it is possible to downsize the base part, and in combination with the pedestal being maintained vertically in place during the construction of the free access floor,
Free access floor construction becomes easy.
