Abstract

PURPOSE: To maintain the floor level the same as it was installed by a method wherein white marble grains or the like put for filling into a joint and a space between the outside of an inner cylinder of a seat and the inside of an outer cylinder of a base is made to flow into gaps produced by subsidence of ground. CONSTITUTION: A floorboard supporter is fixed, with adhesive 24 applied to the bottom of its base 2, to a specified position on a concrete slab 23, and after curing white marble grains or dried sand 15 are poured through an inlet on the top board of a seat 3 so that the poured material rises above the brim of the inlet. Then, adjustment is made to the level with the seat 3 turned by hand. After strips 25 are laid all over the circumference of a room, the strips 25 are laid lengthwise and breadthwise at specified intervals, and all of the seats are fixed with screws from the surface of the batten plates. Then, floor panels 26 and finishing materials 27 are stuck to the surface of the strips 25. When ground subsides uniformly, gaps produced between the floorboards and the bottom of joints are filled with white marble grains 15 dropping by gravity, and the level of the floor surface is maintained the same as it was constructed. In the case of uneven settlement, the seat 3 is kept upright by appropriate gaps produced between the outside of an inner cylinder of the seat 3 and the inside of an outer cylinder of the base 2.

儀なくされていた。2. Description of the Related Art Conventionally, a floor structure has been constructed by a conventional construction method which is constituted by flooring, daiki, joists and the like. According to this method, not only the skill level is required for the selection and processing of the material used for each part, but also the construction period is considerably long. In addition, the conventional direct-laying method of directly applying a floor material on a concrete slab poses a problem of noise leakage to the downstairs and the adjoining room due to insufficient sound insulation. Because of lacking in the body, problems such as fatigue to the body occurred.
On the other hand, with the conventional construction method, when the concrete slab tilts or the foundation lowers due to the subsidence of the ground, the floor surface also lowers accordingly, resulting in distortion of the building, resulting in part of the floor surface falling or tilting. It was happening. In order to solve this, there is a double floor construction method, but it requires more complicated steps than the conventional construction method, and it has been forced to increase the construction period and cost burden.

Therefore, a gap is formed between the bottom surface 19 of the joint screwed to the inner surface of the top 3 and the upper portion of the dry sand poured into the outer cylindrical body 6 of the base 2. Then, cold water stones or dry sand filled between the inside of the joint and the outside of the inner cylinder of the top 3 and the inside of the outer cylinder of the base 2 flows into the gap to maintain the floor level position installed during construction. . Further, since an appropriate gap is provided between the outside of the inner cylindrical body of the top 3 and the inside of the outer cylindrical body of the base 2, the ground is sunk unevenly and the central axis of the base 2 is inclined with respect to the central axis of the top 3. Even if it is peeled off, the top 3 is kept vertically installed during construction due to an appropriate gap provided between the outside of the inner cylinder of the top 3 and the inside of the outer cylinder of the base 2.

らの加重を常に均一に受けることができる。FIG. 8 is a front sectional view showing a construction state of the floor board support 1 according to this embodiment, and the construction procedure is as follows. Ink is placed on the concrete slab 23 to determine the installation position of the floorboard support 1. Adhesive 24 on the bottom of the stand 2
Is applied and the floor board support 1 is pressure-bonded to a predetermined position on the concrete slab 23. Then, the adhesive 24 enters into the adhesive hole 9 by the pressure from above and solidifies, so that a stronger adhesive force is obtained. In the case of a foundation that can be nailed instead of the concrete slab 23, the mounting hole 1
It can be fixed by driving a nail into 0. After curing for 1 to 2 days after adhering the base 2, the introduction port 1 of the top plate 11 of the top 3
Cold water stone or dry sand 15 is poured into the upper surface of the inlet 16 from 6 to the extent that it rises. Rotate top 3 by hand to adjust the level. After the strip 25 is stretched around the entire circumference of the room, the strip 25 is stretched at predetermined vertical and horizontal intervals. All the tops 3 are fixed with screws from the upper surface of the strip 25. An adhesive is applied to the upper surface of the strip 25 and the floor panel 26 is nailed after being bonded to the upper surface of the strip 25. The finishing material 27 is pasted on the floor panel 26 to complete the construction. If the floor board support 1 of the present invention is used, even if the concrete slab 23 is inclined at the time of construction, the top 3 and the platform 1 are separated,
Since the top 3 can always be installed horizontally, the weight from the floor surface can always be uniformly received.

The conceptual diagram which shows the state which inclined and settled. There are two types of subsidence after construction: uniform settlement and unequal settlement. In the case of uniform subsidence, a gap is created between the bottom plate 5 and the bottom surface 19 of the joint 4, so that cold water stone or dry sand 15 flows down by gravity and fills the gap. Therefore, the floor level set during construction is maintained without lowering.
In addition, in the case of unequal settlement, if the top 3 and the base 2 are integrated, there is a risk of inclining due to the inclination, but according to the floor plate support 1 of the present invention, the outer diameter of the inner cylindrical body 13 of the top 3 is reduced. Since an appropriate gap is provided between the base 2 and the inner diameter of the outer cylindrical body 6 of the base 2, even if the base 2 is slightly tilted with respect to its center axis due to uneven settlement, the gap causes the top 3 to be vertical during construction. It can be kept installed.

By automatically dropping and filling, the floor surface is always kept constant, so the effect of preventing floor distortion and inclination due to uneven settlement is remarkable, and problems such as difficulty in opening and closing fittings and squealing floors are eliminated. To be done. Furthermore, not only can noise be reduced by providing an appropriate gap between the floor surface and the concrete slab, but the floor surface can be made more elastic than direct tension, so fatigue to the body can be reduced. it can
