[0006] This problem can be solved by reducing the size of the floor support material. However, the work required for construction is increased, and even if the floor support material is small in size, one piece of floor support material must be installed in a horizontal state. Four to six support leg members (pedestals and bolts) must be used for the floor support, which requires a large amount of support leg members, resulting in an increase in cost.

Further, since the above-mentioned conventional floor panel supporting apparatus has an integrated structure in which a plurality of supporting leg members are attached to one floor supporting member, it is cut and used according to the size of a room to be laid. If you have to, cut off the unnecessary parts,
Work such as replacement of the supporting leg members according to the size of the floor support material after cutting is required, and the construction is troublesome.

FIG. 1 shows an example of the construction of a floor panel supporting apparatus according to the present invention. The pedestal 1, a column 2 supported by the pedestal 1 in an upright state, a supporting plate 3, and a fixed member fixed to the supporting plate 3. And a receiving seat 4 which is attached and engages the upper end of the support 2.

The pedestal 1 is made of an elastic material such as a rubber-based, foamed rubber-based, synthetic resin-based or foamed synthetic resin-based material, so that the impact force can be buffered and absorbed. The shape of the pedestal 1 is arbitrary, and is not limited to the illustrated one having a substantially trapezoidal cross section, and may be, for example, a rectangular shape or a square shape. When the bottom surface of the pedestal 1 is an uneven surface, when installed on the floor base, the void formed between the base and the floor base functions as a buffer layer, so that the impact force is more effectively buffered and absorbed. be able to. If it is not necessary to absorb and absorb the impact force by the pedestal 1, it may be made of wood, metal or the like.

The column 2 is made of metal, synthetic resin, or the like.

The support 2 has a round bar 6 at the lower end having an outer diameter corresponding to the diameter of the non-through hole 5 formed at the center of the upper surface of the pedestal 1. Through hole 5
A flange 7 having a diameter sufficiently larger than the diameter of the flange 7 and a bolt 8 extending above the flange 7 are integrally formed. A concave groove 9 is formed at the tip of the bolt portion 8. The column 2 is rotatably supported relative to the pedestal 1 by inserting the lower round bar 6 into the non-through hole 5 of the pedestal 1.

As the support plate 3, plywood (LVL, LVB)
Etc.), a fiber board, a particle board, a wood board, a synthetic resin board, or the like, and a rectangular shape having one side of 5 to 20 cm and an arbitrary thickness. The reason why one side is 5 to 20 cm is that if it is smaller than this, the holding area of a floor panel described later becomes insufficient, and if it is larger than this, the weight increases and it becomes difficult to handle.

The support plate 3 has a support 2 supported on the pedestal 1.
A through-hole 10 is formed at a position aligned with the bolt portion 8 of FIG. This through hole 10 has a diameter sufficiently larger than the bolt diameter.

On the support plate 3, an elastic protruding piece 27 made of an arbitrary elastic material such as rubber, foamed rubber, synthetic resin, and foamed synthetic resin is adhered. The elastic protruding piece 27 has a width dimension equal to or larger than the diameter of a floor plate height adjusting hole 14 described later.

The elastic protruding piece 27 has a hole 1 opened in the support plate 3.
4 and 4, for example, provided at positions as shown in FIGS. Then, an adhesive layer 16 whose surface is coated on a release paper 17 is laminated on the surface of the support plate 3 excluding the elastic protrusions 27.

The metal or synthetic resin seat 4 has a nut 11 at the lower end on which a female screw for screwing the bolt 8 of the column 2 is formed, and an enlarged diameter formed above the nut 11. And a cylindrical portion 1 at an upper end above the receiving flange 12 and fitted into the through hole 10 of the support plate 3.
3 are integrally formed. The upper end cylindrical portion 13 is bonded and fixed to the through hole 10 of the support plate 3 using an adhesive. Alternatively, after the upper end cylindrical portion 13 is inserted into the through hole 10, the upper end cylindrical portion 13 may be fixed by caulking from the upper portion and widening the front end opening. Adhesion and fixing by swaging may be used in combination.

A female screw for screwing the bolt 8 of the column 2 is formed in the nut 11 at least at the lower end, and a hole 14 opening to the upper surface of the flooring support device is formed in the upper cylindrical portion 13. Provided.

On the other hand, as the floor panel 20, materials such as plywood (including LVL and LVB), fiberboard, particle board, wood board, and synthetic resin board are used.

It is preferable to reduce the size of the floor panel 20 in order to make it easy to carry and improve the workability. However, if the size is too small, the number of sheets required for the work increases, and the work becomes complicated. Become. Further, if the length is too large relative to the width, bending in the longitudinal direction is likely to occur when a load is applied.
For these reasons, the floor panel 20 has a width of 30 to 7 mm.
It is preferable to be 5 cm x 90 to 300 cm in length,
More preferably 45-75 cm in width x 180-240 in length
cm.

The above-mentioned floor panel support device and floor panel 2
The procedure for constructing a floor by using a combination of zeros will be described below with reference to FIGS.

First, a joist 19 made of wood, plywood, or the like is nailed to a predetermined position on a wall surface of a room where a floor is to be constructed, using a bundle (not shown) as a support.

Next, several places (two places in the illustrated example) of the back surface along one side edge 21 in the longitudinal direction of the floor panel 20 and the back part of one end corner 22 thereof are respectively connected to the above-mentioned floor plate supporting device. Place on top. At this time, the release paper 17 at the portion where the floor panel 20 is placed is removed to expose the adhesive layer 16, and the floor panel 2 is placed via the adhesive layer.
By adhering to the required portion of the back surface of No. 0, the floor panel 20 and the floor panel support device are temporarily fixed to form one unit body, so that the work can be easily performed.

When the side edge portion of the floor panel 20 is placed on the support plate 3, the hole 14 opened on the upper surface of the support plate 3 must be prevented from being concealed by the floor panel 20, but in the present invention. Since the elastic protrusion 27 is provided on the support plate 3 and the adhesive layer 16 and the release paper 17 are provided on the surface of the support plate 3 excluding the elastic protrusion 27, the release paper 17 is provided.
When placing the floor panel 20 on the adhesive layer 16 that is exposed after removing the floor, the floor panel 20 can be positioned and abutted against the side surface of the elastic protruding piece 27 and positioned. it can. In other words, the elastic projection 27 is placed and adhered so as to match the side edge 21 of the floor panel 20, so that the work at a predetermined position can be easily performed.

As shown in FIG. 2, the floor panel 20 to which the support plate 3 of the floor panel support device is temporarily fixed is connected to the other side edge 23 in the longitudinal direction and one side edge 24 in the width direction. Place on 19. That is, the floor panel 20 is laid so that the corner 22 of the floor panel 20 to which the support plate 3 is temporarily fixed is positioned diagonally to the corner of the room.

After laying, the column 2 is rotated by inserting a screwdriver (not shown) through the hole 14 of the base plate 3 and engaging with the concave groove 9 so that the base plate 3 is at the same level as the joist 19. Is adjusted so that the floor panel 20 is horizontal.

With the above operation, the laying of the first one floor panel 20 is completed.

In the same manner, the back surface portion along the longitudinal side edge or the width direction side edge of the supporting plate 3 of the floor panel supporting device temporarily fixed to the joist 19 or the floor placing panel 20 laid earlier. The floor placing panels 20 are sequentially laid so as to be placed on the opposite side of the upper surface (FIG. 2). Regarding the floor panel 20 laid last in each row or each stage,
It is cut in accordance with the interval size, and one side edge is placed on the support plate 3 of the floor panel support device temporarily fixed to the floor panel 20 laid first, and the other side edge is cut with the joist 19
Place on top.

By repeating such laying work and laying the floor panel 20 over the entire room as shown in FIG. 3, nails, staples and the like are driven into each support plate 3 from above each floor panel 20. And fix them. Also, if necessary, by inserting a joint material into the gap between the joints between the floor placing panels 20, or by attaching a joint tape or the like,
Apply joint treatment.

Thus, the desired floor material is fixed directly on the floor panel 20 laid on the entire room using an adhesive or a nail or the like, or the discarded plywood is fixed using an adhesive or a nail. By doing so, a floor-standing structure is obtained. FIG.
Shows a floor placement structure obtained by fixing the floor material 26 on the floor placement panel 20 via the discarded plywood 25.
When the discarded laminated board 25 and the flooring material 26 are fixed, if the connecting portions thereof overlap with the butted portions at intervals of the floor placing panels 20, the strength against the load from the floor surface becomes insufficient. Therefore, they are arranged so that they do not overlap.

Examples of the floor material include a wooden floor, a wooden floor having a cushioning material adhered to the back surface, a rug such as a carpet, a floor tile, and a tatami mat.

Further, a floor can be formed by applying a floor coating material to the surface of the discarded laminated board 25.

FIG. 5 shows a modified example of the floor panel support device, in which the upper end cylindrical portion 13 of the seat 4 has a larger diameter than the nut portion 11, so that the bolt portion 8 of the support column 2 has the nut portion. 11 and the upper end cylindrical portion 13
A gap 15 is formed between the bolt and the bolt portion 8.

After adjusting the height of the support plate 3 and the floor panel 20 in the manner described above, the space 15 is filled with a room temperature-curable resin or adhesive (including a foaming adhesive and a foaming adhesive). ) Is injected. The injected resin fills the gap 15 and partially penetrates into the nut portion 11.
As the injected resin hardens, the bolt portion 8 is completely fixed to the receiving seat 4, and an additional effect that the support plate 3 is fixedly held at a predetermined height position is obtained.

[0037]

According to the present invention, since the floor panel support device and the floor panel are provided as separate members, the floor panel support device can be attached after cutting the floor panel to required dimensions during construction. The construction can be performed more efficiently and at lower cost than in the case where these floor plate supporting devices are of an integral type which is fixed to the back surface portion of the floor panel in advance.

Since at least a sufficient interval is provided between adjacent floor placing panels to expose through holes formed in the support plate of the floor plate support device for height adjustment, There is no room for the floor squealing problem due to the later contact of these lips.

Since the floor panel can be provided as a relatively small one, it is easy to transport and construct.

The floor panel supporting device supports the portion along the side edge of the floor panel, and furthermore, one floor panel supporting device supports the opposing side edge portions of two adjacent floor panels. The number of supporting devices used can be reduced, which contributes to a reduction in labor and cost for construction.

Since elastic projections having side surfaces are provided on the surface of the support plate of the floor plate support device at positions serving as alignment marks for the floor panel, it is easy to construct the floor panel on the support plate. is there.

The side edge of the floor panel is in contact with the side surface of the elastic protruding piece, but since it is made of an elastic material, it has a buffering effect.
