Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a double floor structure used for a floor surface of a computer room or the like.

(Prior Art) Conventionally, in laying a floor panel in this type of double structure, engagement between a pedestal screwed to a support leg and a floor panel is performed by four engaging projections formed on the pedestal. It was done with the recess formed at the lower end of the floor panel.

(Problems to be solved by the invention) However, in the case of forming four engaging projections on the pedestal of the support leg in this prior art, by cutting the lump having the height of the projection, Part 4 with the pedestal
Since it is necessary to form the individual engaging projections, there is a problem that it takes time and labor and the processing cost rises.

Further, as shown in FIG. 9, the details of the engagement between the pedestal and the floor panel are as shown in FIG.
And the projections (100 ') of the recesses (101') on the rear surface of the floor panel (101) which are just engaged.

Therefore, when setting the floor panel (101), the edge of the recess (101 ') at the lower end of the floor panel (101) is caught on the upper surface of the projection (100') to guide the projection (100 ') into the recess (101'). In some cases, it is necessary to perform fine adjustment work to move the floor panel (101) back and forth and left and right.

The present invention has been made in view of the above conventional circumstances, and its purpose is to provide a pedestal formed by adding a perforating process to a metal plate material, and a spacer interposed between the pedestal and the floor panel. By using it to support the floor panel on the pedestal, we aim to reduce the total cost and
Protect the floor panel from the pedestal by the buffering property of the spacer,
In addition, it is intended to smoothly and easily engage the concave portion provided on the back surface of the floor panel and the protrusion of the spacer to improve workability in positioning the floor panel.

(Means for Solving the Problems) The technical means taken to achieve the above technical problems are:
The pedestal has a positioning hole and is screwed into the supporting leg, and a spacer made of synthetic resin having hemispherical projections at the positions corresponding to the positioning hole in a vertically back-to-back shape. The gist is that the body-shaped protrusion is loosely fitted in the alignment hole, and the upward hemispherical protrusion is engaged with the recess formed in the lower end of the floor panel.

(Operation) According to the above technical means, the downward hemispherical projection is fitted into the positioning hole of the pedestal in which the positioning hole is opened by the boring process, and the spacer made of synthetic resin is attached to the pedestal. Place it,
The recesses at the lower end of the floor panel are engaged with the upward hemispherical projections of the spacers to support the floor panel on the pedestal.

Further, the edge of the recessed portion at the lower end of the floor panel is slid on the outer circumferential arc surface of the upward spacer of the corresponding spacer to lower the floor panel.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

First, the first embodiment shown in FIGS. 1 and 2 will be described. (A) is a base surface, (a) is a floating floor, (B) is a floor panel, (1) is a support leg, and (4) is It is a spacer.

The support leg (1) has a double nut (1) on the upper side of the screw strut (1a).
b) (1b) has a well-known structure in which the pedestal (2) is vertically movable, and the seat plate (1c) is integrally attached to the lower end, and alignment holes are provided at the four corners of the pedestal (2). (3) has been established.

The floor panel (B) is made of a metal material such as an aluminum alloy or any other desired material and has a conventionally well-known structure having a side of about 50 cm. The leg seats (8) are protruded at the four corners of the rear surface. Recesses (9) are formed in the lower surface of the leg seat (8).

As shown in FIGS. 4 to 7, the spacer (4) is made of polypropylene or the like having the same area as the pedestal (2) excluding the double nuts (1b) (1b) of the support leg (1). A thin plate made of resin material is divided into four pieces and has a cushioning function. Each spacer (4) ... has an upward hemispherical projection (5) and a downward hemispherical projection on the upper and lower surfaces, respectively. Division (6)
Are integrally molded.

The protrusions (5) and (6) each have a hemispherical shape, and the upward hemispherical protrusion (5) engages with the recessed portion (9) of the floor panel (B) to form a downward hemispherical protrusion. The portion (6) is provided so as to be vertically back to back so as to be loosely fitted in the alignment hole (3) formed at the corner of the pedestal (2).

Further, the upward hemispherical projections (5) ... do not need to be completely hemispherical, and the recesses (9) of the floor panel (B) are not required.
A substantially hemispherical shape having an arc of such a size that the edge does not get caught when sliding down the outer periphery of the upward hemispherical projection (5) ... It can be one.

Further, the respective spacers (4) ... Can be independently moved slightly forward, backward, leftward and rightward by connecting the end faces to each other via the expandable portion (7).

This is because the position of the alignment hole (3) of the pedestal (2) and the downward projection hemispherical projection (6) of each spacer (4) ... Even so, the downward hemispherical projections (6) of the spacers (4) ... Can be reliably fitted into the alignment holes (3) by following the error.

The expansion / contraction part (7) has a desired shape such as a thin V-shaped piece or W-shaped piece made of a synthetic resin material that can be expanded and contracted so that each spacer (4) can be independently moved slightly forward, backward, leftward and rightward. It is configured by connecting the formed connecting pieces (7 ') over the adjacent spacers (4) ... End surface.

It is also possible to mold the expandable portion (7) with the same synthetic resin material as the spacers (4). By doing so, molding can be performed at a lower cost.

This connecting piece (7 ') is formed to have a strength such that it can be separated by an artificial pulling action so that each spacer (4) can be used separately.
It can be as thick as ... or thick.

4 and 5 show the expansion / contraction portion (7) in a V-shape on the plane, and FIGS. 6 and 7 show the expansion / contraction portion (7) on the plane U.
In addition to being shaped like a letter, it is formed large and the range of expansion and contraction is enlarged.

Then, the case of laying a floating floor using the level adjusting device of the first embodiment will be explained. The support legs (1) erected on the base surface (A) are respectively formed at the four corners of the pedestal (2). Each of the downward hemispherical protrusions (6) is fitted into the aligned alignment hole (3), and four pieces of the spacer (4) are attached to the pedestal (2).
Place on.

Next, while sliding the edge of the recess (9) of the floor panel (B) from above to the upward hemispherical protrusion (5), the floor panel (B)
To lower the concave portion (9) into the upward hemispherical projection (5).
To form a floating floor (a).

Next, the second embodiment will be described with reference to FIG. 3. In this embodiment, the level of the floor panel (B) is finely adjusted by using a tool such as a driver (200) on the floor panel (B). This is an example of a level adjustment device having a fine adjustment mechanism (C) capable of performing the adjustment.

The fine adjustment mechanism (C) fixes the mounting nut (11) on the back surface of the floor panel (B) so as to communicate with the through hole (10) formed in the corner, and the height adjustment bolt is fixed to the mounting nut (11). (12) is screwed so that it can move back and forth, and the bolt (12) has the through hole (10).
It is possible to adjust the level of the floor panel (B) on the pedestal (2) separately from the pedestal (2) by inserting and retracting a tool such as a driver (200) from the
At the lower end of the height adjusting bolt (12) of the fine adjustment mechanism (C), a bag-like locking tool (13) having an upward recess (9) is provided.

The bag-like engaging member (13) is the base end of the upward hemispherical projection (5) of the corresponding spacer (4) placed on the pedestal (2) as in the first embodiment. The lower end open edge of the recess (9) is adapted to engage with the portion.

Then, the case of laying a floating floor using the level adjusting device of the second embodiment will be explained. As in the first embodiment, four pieces of spacers (4) are attached to the pedestal (2) of the spindle leg (1). To place.

Next, from above, the recess (9) in the bag-like locking device (13)
The floor panel (B) is moved down while sliding the lower open edge of the upper hemispherical protrusion (5) in the same manner as in the first embodiment, and the base end of the upper hemispherical protrusion (5) is lowered. The floor panel (B) is set on the pedestal (2) by engaging the recess (9) with the section.

Level adjustment is performed in this state.

Incidentally, (14) is a four-corner protection plate provided with a burring portion (14 ') which engages with the hole edge of the through hole (10).
By integrally mounting the mounting nut (11) on the corner protection plate (14), when the plate (14) is bonded to the back surface of the floor panel (B) with a strong instant adhesive (15), the burring portion (1
The guide function of 4 ') allows the mounting nut (11) to be reliably and easily aligned with the through hole (10).

Note that (16) is a border panel.

Thus, when the border panel (16) is placed on one side, the leg (17) of the border panel (16) fits into the alignment hole (3), so the spacer (4) is unnecessary. At this time, the unnecessary spacer (4) may be separated by cutting the stretchable portion (7).

(Effects of the Invention) As described above, the present invention relates to the pedestal in which the alignment hole is opened by the drilling process, the downward hemispherical protrusion that is fitted into the alignment hole, and the recess on the back surface of the floor panel. With a spacer made of synthetic resin and having an upward facing hemispherical protrusion, the protrusion for engaging the floor panel can be replaced with a conventional pedestal formed by cutting a lump. Therefore, the processing cost of the pedestal is low, and the spacer can be molded at a low cost by using the synthetic resin material, so that the total cost can be reduced.

Also, even if the floor panel is lowered while sliding the recessed portion at the lower end of the floor panel to the upward hemispherical protrusion of the spacer, the protrusion shape forms an arc surface, so the edge of the recessed portion at the lower end of the floor panel is Since the parts do not get caught and they engage smoothly, the floor panel can be easily positioned and the workability can be improved.

Further, since the buffer spacer made of a synthetic resin material is interposed between the floor panel and the pedestal, the floor panel does not come into contact with the pedestal, and there is no fear that the floor panel will be scraped by the pedestal due to weighting.
