Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a floor plate supporting device used for a floor structure for constructing floor plates on a floor of an apartment house, an office, or the like at predetermined intervals.

[0002]

[Prior Art]

 Conventionally, for example, a method of constructing a floor using a floor board supporting device having a structure as described in Japanese Utility Model Publication No. 54-3542 is adopted. This floor board support device is provided with play holes in at least each corner of a rectangular floor support, and bolts are screwed or fitted into the play holes.On the other hand, on a pedestal placed in a proper place on the floor base such as mortar. The lower end of this bolt is screwed to support the bolt in an upright state.

In this way, the floor supports are sequentially attached and spread, and the height of the floor supports is adjusted by inserting a screwdriver from above the play hole and rotating the bolts. By placing a desired floor finishing material on the above-mentioned floor support material, the floor is constructed.

[0004]

[Problems to be solved by the device]

 The floor support materials used in the above-mentioned conventional floor board support equipment are laid and processed without gaps, so that the openings of the floor support materials may come into contact with each other during walking after construction. There was a problem that floor noise occurred.

Further, since it is assumed to be laid and installed, it is provided as a relatively large size, so that it is difficult for one person to carry and work alone, and workability is poor. there were.

This problem can be solved by reducing the size of the floor support material. However, as the construction work increases, even if the floor support material of a small size is installed, it is necessary to install one floor support material in a horizontal state. For the floor support, 4 to 6 support leg members (pedestal and bolt) must be used, and a large amount of support leg members is required, which causes an increase in cost.

Further, since the above-mentioned conventional floor board supporting device has an integral 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 the room to be laid. If it is necessary to do so, it is necessary to cut unnecessary parts and replace the supporting leg members according to the size of the floor support after cutting, which is troublesome for construction.

[0008]

[Means for Solving the Problems]

 Therefore, the present invention proposes a novel floor-standing structure that can solve the above-mentioned drawbacks of the prior art, and an object thereof is to provide a floor board support device used in this floor-standing structure.

That is, according to the present invention, the pedestal installed on the floor base and the pedestal supporting the supporting plate are connected by the supporting column, and the supporting column is relatively rotated through the through hole formed in the supporting plate. A floorboard support device configured to adjust the height interval between the pedestal and the pedestal, a flooring panel installed on the support plate of the floorboard support device, and a floor installed on the flooring panel. A floorboard supporting device used in a flooring structure in which materials are combined with each other, wherein abutting portions of a plurality of flooring panels adjacent to each other on a supporting plate of one floorboard supporting device conceal the through holes of the supporting plate. The elastic protrusions are mounted on the support plate at intervals so that the elastic protrusions have a width dimension equal to or larger than the diameter of the through hole. Is provided, and the side surface of the elastic protrusion faces the flooring panel. It is used as a reference plane for alignment.

[0010] Preferably, an adhesive layer having a surface coated with a release paper is provided on the surface portion of the support plate excluding the protruding piece.

[0011]

Embodiment FIG. 1 shows an example of the construction of a floor board supporting device according to the present invention. A pedestal 1, a column 2 supported by the pedestal 1 in an upright state, a support plate 3, and a support plate 3 are provided. It is composed of a receiving seat 4 which is fixedly mounted and engages the upper end of the support column 2.

By forming the pedestal 1 from an elastic body such as a rubber-based, foamed rubber-based, synthetic resin-based, or foamed synthetic resin-based material, the impact force can be absorbed and absorbed. The shape of the pedestal 1 is arbitrary and is not limited to the substantially trapezoidal cross section shown in the figure, and may be, for example, a rectangular shape or a square shape. Also, when the bottom surface of the pedestal 1 is made uneven, the space formed between the pedestal 1 and the floor base functions as a buffer layer when installed on the floor base, so it is more effective in absorbing and absorbing impact force. Can be done. If it is not necessary to absorb and absorb the impact force by the pedestal 1, it may be made of wood or metal.

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

The pillar 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 in the central portion of the upper surface of the pedestal 1, and a non-circular shape of the pedestal 1 formed above the round bar 6. A brim portion 7 having a diameter sufficiently larger than the diameter of the through hole 5 and a bolt portion 8 extending above the brim portion 7 are integrally formed. A groove 9 is formed at the tip of the bolt portion 8. The support rod 2 is supported so as to be rotatable relative to the pedestal 1 by inserting the round bar 6 at the lower end thereof into the non-through hole 5 of the pedestal 1.

As the support plate 3, materials such as plywood (including LVL, LVB, etc.), fiber board, particle board, wood board, synthetic resin board, etc. are used, and one side has a rectangular shape of 5 to 20 cm and an arbitrary thickness. It is said that. The length of one side is set to 5 to 20 cm, because if it is smaller than this, the holding area of the flooring panel described later becomes insufficient, and if it is larger than this, the weight increases and it becomes difficult to handle.

Through holes 10 are formed in the support plate 3 at positions aligned with the bolt portions 8 of the support columns 2 supported by the pedestal 1. The through hole 10 has a diameter sufficiently larger than the bolt diameter.

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

The elastic protrusion 27 is provided at a position outside the hole 14 opening in the support plate 3, for example, at a position shown in FIGS. 6 and 7. Then, on the surface portion of the support plate 3 excluding the elastic protrusions 27, the adhesive layer 16 surface-coated with the release paper 17 is laminated and formed.

The metal-made or synthetic-resin seat 4 has a lower-end nut portion 11 on which a female screw for screwing a bolt portion 8 of the support column 2 is engraved, and an enlarged diameter is formed above the nut portion 11. The receiving brim portion 12 and the tubular portion 13 at the upper end which is above the receiving brim portion 12 and is fitted into the through hole 10 of the support plate 3 are integrally formed. The upper end tubular portion 13 is adhesively fixed to the through hole 10 of the support plate 3 using an adhesive. Alternatively, after the upper end tubular portion 13 is inserted into the through hole 10, the upper end tubular portion 13 may be caulked from the upper portion and the tip end opening may be widened to be fixed. Adhesion and fixing by caulking may be used together.

At least the nut portion 11 at the lower end is internally engraved with a female screw into which the bolt portion 8 of the column 2 is screwed, and the upper end tubular portion 13 has a hole 14 that opens to the upper surface of the flooring support device. Is provided.

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

The size of the floor panel 20 is preferably small for easy carrying and good workability, but on the other hand, if it is too small, the number of sheets required for construction increases and the construction becomes rather troublesome. .. If the length dimension is too large with respect to the width dimension, bending in the longitudinal direction tends to occur when a load is applied. For these reasons, the flooring panel 20 preferably has a width of 30 to 75 cm and a length of 90 to 300 cm, more preferably a width of 45 to 75 cm and a length of 180 to 240 cm.

A procedure for constructing a floor by using the floor board support device and the floor panel 20 described above in combination will be described below with reference to FIGS. 2 and 3.

First, a joist 19 such as wood or plywood is nailed and fixed to a predetermined position on the wall surface of a room where flooring is to be performed, using a bundle (not shown) as a support.

Next, several places (two places in the illustrated example) of the back surface portion along one longitudinal edge 21 of the flooring panel 20 and the back surface portion of one end corner 22 thereof are respectively attached to the floor board supporting device described above. Place on top. At this time, the release paper 17 in the portion on which the floor placement panel 20 is placed is removed to expose the adhesive layer 16, and the adhesive layer 16 is adhered to the required back surface portion of the floor placement panel 20 via this adhesive layer, thereby providing the floor placement panel. Since the 20 and the floor board supporting device are temporarily fixed to form one unit body, the work can be easily performed.

When the side edge portion of the floor placement panel 20 is placed on the support plate 3, it is necessary to prevent the hole 14 that opens on the upper surface of the support plate 3 from being hidden by the floor placement panel 20. In the present invention, since the elastic projection piece 27 is provided on the support plate 3 and the adhesive layer 16 and the release paper 17 are provided on the surface portion of the support plate 3 excluding the elastic projection piece 27, the release paper 17 is removed. When the flooring panel 20 is placed on the adhesive layer 16 that is exposed later, the flooring panel 20 can be placed in contact with the side surface of the elastic protrusion 27 while being aligned. .. That is, the elastic protrusion 27 is placed on and adhered to the side edge 21 of the flooring panel 20 so that it can be easily installed at a predetermined position.

In this way, as shown in FIG. 2, the floor placement panel 20 to which the support plate 3 of the floor plate support device is temporarily fixed is attached to the other side edge 23 in the longitudinal direction and one side edge 24 in the width direction as a thick joist. Place on top of 19. That is, the floor placement panel 20 is laid so that the corners 22 of the floor placement panel 20 to which the support plate 3 is temporarily fixed are located diagonally to the corners of the room.

After laying, the pillar 2 is rotated by inserting a driver (not shown) into the hole 14 of the base plate 3 and engaging the groove 9 with each other. The height is adjusted so that the floor placement panel 20 is horizontal.

By the above work, the laying of the first one floor placement panel 20 is completed.

In the same manner, the back plate along the longitudinal side edge or the widthwise side edge is temporarily fixed to the thick joist 19 or the floor laying panel 20 laid previously, and the supporting plate 3 of the floor board supporting device. The floor placement panels 20 are sequentially laid so that they are placed on the opposite side of the upper surface (FIG. 2). The floor panel support device, which is finally laid in each row or each stage, is cut according to the space dimension and one side edge is temporarily fixed to the floor panel 20 laid first. It is placed on the support plate 3 and the other side edge is placed on the joist 19.

After laying down the flooring panels 20 in the entire room by repeating such laying work as shown in FIG. 3, nails, staples, etc. are driven into the respective support plates 3 from above each flooring panel 20. Then, fix them. If necessary, a joint material is inserted into the gap between the seams of the flooring panel 20 or a joint tape is applied to perform joint treatment.

Thus, the flooring panel 20 laid in the entire room is fixed directly or after a discarded plywood is fixed with an adhesive or a nail, and then a desired floor material is fixed with the adhesive or a nail. By putting on, a floor-standing structure is obtained. FIG. 4 shows a floor placing structure obtained by fixing a floor material 26 on a floor placing panel 20 via a bonding plate 25. When the discarding laminated plate 25 and the floor material 26 are fixed, if their connecting portions overlap the abutting portions of the floor placing panels 20 spaced apart from each other, the strength against the load from the floor surface becomes unsatisfactory. It will be sufficient so that they are arranged so that they do not overlap.

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

The floor can also be constructed by applying a floor coating material to the surface of the throw-off laminated plate 25.

FIG. 5 shows a modified example of the floor board supporting device, in which the upper end tubular portion 13 of the receiving seat 4 has a larger diameter than the nut portion 11, so that the bolt portion 8 of the column 2 is a nut. A gap 15 is formed between the upper end tubular portion 13 and the bolt portion 8 in a state of being screwed into the portion 11.

After the heights of the support plate 3 and the floor placement panel 20 are adjusted in the above-described manner, the void 15 contains a room temperature curable resin or adhesive (foaming adhesive, foaming adhesive). ) Is injected. The injected resin fills the space 15 and partly penetrates into the nut portion 11. By hardening the injected resin, the bolt portion 8 is completely fixed to the seat 4, and the support plate 3 is fixedly held at a predetermined height position, which has an additional effect.

[0037]

[Effect of the device]

 According to the present invention, since the floor plate supporting device and the floor placing panel are provided as separate members, the floor plate supporting device can be attached after cutting the floor placing panel to a required size during construction. Compared to the case where the device is an integrated type that is fixed to the back side of the floor panel in advance, construction can be performed more efficiently and at lower cost.

At least a sufficient space is provided between the adjacent floor placement panels so as to expose the through holes provided in the support plate of the floor plate support device for height adjustment. There is no room for the problem of floor ringing due to the contact of these cusps later.

Since the flooring panel can be provided as a relatively small size, it can be easily transported and processed.

The floor board supporting device supports a portion along the side edge of the floor placing panel, and since one floor board supporting device supports opposite side edge portions of two adjacent floor placing panels, The number of floor board support devices used is small, which contributes to reduction of construction labor and cost.

Since an elastic protrusion having a side surface is provided on the surface of the support plate of the floor plate supporting device at a position that serves as an alignment mark for the floor plate, it is possible to process the floor plate on the support plate. It's easy.

The side edge of the floor placement panel is brought into contact with the side surface of the elastic protrusion, but since it is made of an elastic material, it has a cushioning effect.
