Description

[Detailed explanation of the idea]

[Industrial Application Field] The present invention is a floating floor support device used when constructing free access floors, soundproof floors, etc. and a fixture for fixing the floor member to a support member, and the floor member is provided with a hole for vertically operating the height adjuster and the fixture. . [Prior Art] As shown in FIG. 4, in this type of floating floor support device, the upper ends of the height adjusting tool 5 and the fixing tool 6 are connected to the upper surface of the peripheral portion of the operating holes 4 and 8. The operating hole 4,
It is known that the height adjusting tool 5 and the fixing tool 6 are configured to have a large diameter so that the height adjusting tool 5 and the fixing tool 6 can be assembled and operated with sufficient margin (I can't provide any literature). [Problems to be solved by the invention] In this conventional floating floor support device, each of the operation holes 4 and 8 is covered with a floor finishing material 7 such as a carpet laid on the floor member 2. Although used, between the floor finishing material 7, the inner circumferential surface of the operating hole 4, and the outer circumferential surface of the height adjuster 5, and
Since there are large recesses in the shape of an inverted concave between the floor finishing material 7, the inner peripheral surface of the operating hole 8, and the outer peripheral surface of the fixing device 6, the heel of the shoe is placed over these recesses. In particular, when the heel of women's shoes is positioned, only the portions of the floor finishing material 7 corresponding to these operating holes 4 and 8 support the large stepping load of the heel, and as a result, the floor finishing material 7 Not only does it become recessed and deformed into the operation holes 4 and 8, and debris and the like accumulate in the recessed deformed portion, but in extreme cases, the floor finishing material 7 may be penetrated and damaged. In particular, the height adjuster 5 is larger in volume than the fixture 6 because it needs to support not only the load of the floor member 2 but also the load of equipment and people. Since the diameter of the operation hole 4 also increases accordingly, the above-mentioned problem is likely to occur. The present invention was developed in view of the above-mentioned circumstances, and its purpose is to suppress the deformation and damage of the hole-equivalent portion of the floor finishing member by rationally modifying the height adjuster and fixing device. The point is to make it possible. [Means for Solving the Problems] The floating floor support device according to the present invention is configured such that each upper end of the height adjusting tool and the fixing tool is configured to have the same or almost the same height as the upper surface of the peripheral edge of the operation hole. It is characterized by certain things, and its actions and effects are as follows. [Function] By configuring the upper ends of the height adjuster and the fixing tool to be flush with the upper surface of the peripheral portion of the operation hole, the outer peripheral surface of the height adjuster and the operation The width of the recess formed between the inner circumferential surface of the hole and the floor finishing material such as carpet, and the inner circumferential surface of the operating hole facing the outer circumferential surface of the fixture and the floor finishing material. Since the width of the recessed part formed between the three parts can be made much smaller than that of conventional support devices, the shoe can be placed in the part of the floor covering material that corresponds to the operation hole. Even when the heel portion is positioned, the large stepping load of the heel portion can be received and supported by the height adjuster and the fixture via the floor finishing material. [Effect of the invention] Therefore, it is possible to suppress deformation of the floor finishing material into the operation hole and penetration damage caused by stepping on the heel portion of the shoe. Moreover, since it is only necessary to devise the height of the upper surface of the height adjuster and the fixture as described above, the support device is simpler than, for example, when using a spacer that closes the upper opening of the operation hole. The company was able to achieve its intended purpose while making efforts to improve the situation. [Example] Hereinafter, an example of the present invention will be described based on the drawings. As shown in FIGS. 1 and 2, when configuring a floating floor support device for arranging a plurality of panel-shaped floor members 2 in parallel above a floor base 1 such as a concrete slab, the floor members 2 A height adjuster 5 that can be operated to adjust the height through a vertical operation hole 4 formed between adjacent end edges of the floor member 2 on a support member 3 that is placed and supported at or near the edge of the floor member 2. A fixture 6 is provided to fix the vicinity of the edge of the floor member 2 to the support member 3, and a floor finishing material 7 such as a carpet is laid on the floor member 2. The support member 3 includes a mounting part 3a that is square in plan view and whose peripheral edge is bent downward, and a ground plate 3b that is also formed in a square shape in plan view, In addition, the upper surface of the mounting portion 3a positions the floor members 2 by coming into contact with the adjacent sides of the floor members 2 placed thereon, and also allows the space between the adjacent floor members 2 and 2 to be fixed. protrusion 3 that forms c and prevents the generation of squeaks
C is stamped and formed. The height adjuster 5 includes a first female screw member 5a that is fixed to a diagonal intersection of the mounting portion 3a in a penetrating state.
and a second female threaded member 5b having a thread opposite to that of the first female threaded member 5a, which is fixed to the diagonal intersection of the ground plate 3b, and both of these female threaded members 5a,
5b, and a male threaded member 5c which is screwed into the male threaded member 5b, and a groove 5d for rotational operation is formed at the upper end of the male threaded member 5c. The fixture 6 is mounted on the mounting portion 3a of the support member 3.
An operation hole 8 formed through near the edge of the floor member 2
A positioning convex portion 3d that fits into the operation hole 8 is formed in a bulging manner at a location corresponding to the convex portion 3d.
A presser member 6 having a countersunk shape and having a female thread formed at the center thereof and abutting on the upper surface of the periphery of the operation hole 8.
a, and a headed bolt 6b inserted into the holding member 6a from above is screwed into the female thread of the convex portion 3d, and by tightening the headed bolt 6b, the supporting member 3 and the holding member 6a are screwed together. The structure is such that the floor member 2 is clamped and fixed between them. The first female screw member 5 of the height adjuster 5
a, the upper surface of the adjacent end of the floor member 2 constituting the operation hole 4, and the headed bolt 6 of the fixture 6.
The upper surface of b and the upper surface of the peripheral portion of the operating hole 8 are located in the same horizontal plane, and the space is formed between the outer peripheral surface of the first female screw member 5a and the inner peripheral surface of the operating hole 4. S ₁ , the space formed between the outer circumferential surface of the headed bolt 6b and the inner circumferential surface of the pressing member 6a opposing thereto S ₂ , and the inner diameter d of the first female screw member 5a are each configured to be 10 mm or less, preferably 7 mm or less. Therefore, during use, the operation hole 4,
Even if the heel part H of the women's shoe is located on the top of the heel part 8, the large stepping load of this heel part H is transferred through the floor finishing material 7 to the first female screw member 5a of the height adjuster 5 and the head of the fixture 6. Since it can be reliably received and supported by the bolt 6b, deformation of the floor finishing member 7 into the operation holes 4 and 8 and penetration damage can be suppressed. The present inventor measured the loads of shoes and equipment acting on the floor finishing material 7.

[Table] Then, one side of the operation hole 4, which is rectangular in plan view, is 17
mm, inner diameter d of the first female threaded member 5a of the height adjuster 5
is 10 mm or less, and the distance formed between the outer circumferential surface of the first female threaded member 5a and the inner circumferential surface of the operation hole 4 is ₇ mm.
A comparative test was conducted between the supporting device of the present invention constructed as follows and the conventional supporting device shown in FIG. 4. As for the load conditions, we selected 10φ and 7φ of the pin heel, which are particularly problematic, and also the case where the center part of the carpet, which is an example of the floor finishing member 7, is located above the operation hole 4, and the case where the joint part of the carpet is located. I tested it separately.

[Table] As is clear from the above comparison test results,
Compared to conventional support devices, it is possible to suppress deformation of the carpet into the operating hole 4 and damage caused by penetrating the carpet. Next, another example will be described. (a) As shown in FIG. 3, the first female screw member 5
A bottom plate 5f having a hole 5e that only allows insertion of a rotary operating tool such as a screwdriver into the rotating operating groove 5d of the height adjuster 5 may be provided in series at the upper end of the height adjusting tool 5. (b) The shapes of the height adjuster 5 and fixture 6 are not limited to the structures of the above-mentioned embodiments, but can be changed to various shapes. In other words, in relation to the operation holes 4 and 8, if the structure is such that it is possible to suppress deformation of the floor finishing member 7 into the operation holes 4 and 8 and penetration damage,
It may be configured in any shape. Note that although reference numerals are written in the claims section of the utility model registration for convenience of comparison with the drawings, the present invention is not limited to the structure of the attached drawings by such entry.
