JPH07292942A - Support for double floor - Google Patents

Abstract

PURPOSE:To facilitate an adjusting operation by mounting studs upright on fixed plates secured on a foundation floor face, and mounting a panel mount to each stud. CONSTITUTION:Supports A are equally spaced on a foundation floor face B, and a level or the like is used for each support A in leveling a fixed plate 1 horizontally, that is, leveling a stud 2 vertically. Leveling bolts 6 installed on the fixed plate 1 are disengaged to form a space 8 for leveling between the bottom surface of the fixed plate 1 and the top surface of the foundation floor face B to match the inclination of the stud 2. A corner of each floor panel C is placed and supported on the panel mount 3 of each support A, and a height-adjusting nut 5 is adjusted to adjust the height of each floor panel C. Therefore, an adjusting operation for leveling each stud vertically can be easily and surely performed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a double floor support for supporting a floor panel by constructing a double floor (free access floor) in a grid pattern on a foundation floor surface. It's about the legs.

[0002]

2. Description of the Related Art Usually, as shown in FIG. 4, a support leg A of this type has a leg support 2 vertically attached to a fixed plate 1 fixed on a foundation floor B, and a panel is mounted on the leg support 2. The pedestal 3 is mounted so that its height can be adjusted, and the corners of the floor panel C are mounted and supported on the panel mounting pedestal 3.

Therefore, the panel mounting base 3 of each support leg A
Even if the heights of the support legs are aligned, if the leg columns 2 of the support legs are not vertically installed, a step is formed between the corner portions of the floor panels adjacent to each other placed on the panel mounting base 3. Will occur.

Therefore, in the prior art, after the horizontal of the fixing plate, that is, the vertical of the leg support is set by using a level, an adjusting liner a is provided between the fixing plate 1 and the foundation floor B as shown in FIG. It was inserted to adjust the horizontal of the fixing plate, that is, the vertical of the leg support. For this reason, there have been problems in that the work of vertical leveling of the leg columns is complicated and it is necessary to prepare liners for adjusting various thicknesses.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of such a conventional problem, and can easily and accurately perform vertical leveling of a leg column without using an adjusting liner as in the prior art. It is intended to provide a support leg for a double floor that can be carried out.

[0006]

According to the double floor support leg of the present invention which achieves the above object, a leg support is vertically mounted on a fixed plate fixed on the foundation floor, and the leg support is attached to the leg support. A double-floor support leg to which a panel mounting pedestal is attached is characterized in that one or a plurality of level adjusting bolts are installed on the fixing plate so as to be vertically screwed through. It is a thing.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. This example shows an example in which the foundation floor B for laying and constructing a double floor is a beam that is a combination of H-shaped steels. It can also be applied to slab floors or normal concrete foundation floors.

The double-floor support leg A according to the present invention is basically fixed in the same manner as in the conventional art, and is fixed to the foundation floor B to fix and support the leg support 2 in a vertical standing state, and the leg. A panel mounting pedestal 3 which is fitted and mounted on the upper end of the column 2 so as to be vertically movable, and a panel mounting pedestal 3 which is screwed into a male screw 4 formed on the outer peripheral surface of the leg column 2 so as to be screwed. And a height adjusting nut 5 for supporting the corners of the floor panel C on the pedestal 3 for mounting the panel.
The height of the panel mounting pedestal 3, that is, the height of the floor panel C can be adjusted by screwing.

Then, one or a plurality of level adjusting bolts 6 are attached to the fixed plate 1 fixed on the foundation floor B.
Is installed so that it can be screwed through vertically, and fixed plate 1
It is possible to adjust the horizontal of the column, that is, the vertical of the leg support 2.

That is, the fixed plate 1 is formed into a flat plate having a polygonal shape such as a substantially quadrangular plane or a triangular shape or a circular shape, and one or more places thereof, or four corners formed in a quadrangular shape in the embodiment. The level adjustment bolt 6 is screwed in the vertical direction so that it can be screwed through and installed,
The level adjustment bolt 6 is screwed to adjust the horizontal position of the fixed plate 1, that is, the vertical position of the leg support 2. Reference numeral 7 in the drawing is a double nut for fixing the level adjusting bolt 6 so as not to screw inadvertently.

Therefore, when laying and constructing a double floor, H
The support legs A, A, ... Are arranged at equal intervals on a foundation floor B made of shaped steel, and the support plate A, A ,. Put out the vertical level. That is, while looking at the level, etc., the level adjusting bolts 6, 6, ... Installed on the fixing plate 1 (at the four corners thereof) are screwed to make the tip end of the base floor B.
When it is brought into contact with the upper side, a space 8 is formed between the lower surface of the fixed plate 1 and the upper surface of the base floor surface B according to the inclination of the leg support (actually, the inclination of the upper surface of the base floor surface B made of H-shaped steel). Then, the horizontal of the fixed plate 1, that is, the vertical of the leg column 2 is adjusted. Next, after tightening the double nut 7 so that the level adjusting bolts 6, 6, ... Are not accidentally screwed, the fixing plate 1 is welded 9 or an adhesive onto the foundation floor B made of H-shaped steel. The support leg A is fixed to the base floor surface B by adhesion.

Then, the corners of the floor panels C, C, ... Are placed and supported on the panel mounting pedestals 3, 3 ,. The height adjustment nuts 5, 5, ... of the panel are screwed to operate the panel mounting pedestals 3, 3,
By adjusting the height of ..., that is, the height of each floor panel C, C, ..., the double floor laying work is completed.

[0013]

As described above, the double-floor support leg of the present invention has one or more level adjusting bolts mounted on the fixed plate so as to be vertically threadedly penetrated, and therefore, the conventional support leg is not required. The vertical leveling adjustment work of the leg support can be easily and surely performed only by screwing the level adjusting bolt without using the adjusting liner.

Moreover, as compared with the case where the adjustment liner is used as in the conventional case, the vertical level adjustment can be adjusted more accurately.
