2. Description of the Related Art FIG. 5 shows a state in which a floor board (b) is supported by a conventional floor board support (a).
(A) is arranged at an appropriate position on the concrete floor surface (c) and stands upright and supports the talki (d) on which the floor board (b) is placed. The floor board support tool (a) has an adjusting screw (e), and the height H can be adjusted by rotating the adjusting screw (e). When the height H reaches a predetermined value, the fixing nut (f) is tightened and the adjusting screw (e) is locked so that the height H does not change.

By the way, a top plate (g) is integrally formed on the upper end of the adjusting screw (e).
A wooden square base (h) is attached to (g). If the adjusting screw (e) is rotated and raised, the square base (h) can abut the lower surface of the taluki (d) and support the load acting on the floor plate (b). And for soundproofing and antivibration, the floorboard
In order to stably support (b), several floor board supports (a), (a) ... Are generally used, depending on the length of the talki (d).

However, a floor board support for supporting the talki (d)
Even if the number of (a), (a), ... Is large, it is necessary that the square bases (h), (h), ... In other words, if the part is supported in one-sided contact,
The stability of (d) and floor board (b) is impaired, and vibration and soundproofing effects cannot be obtained.

The floor plate (b) must always be horizontal, and therefore the talki (d) on which the floor plate (b) rests must also be supported horizontally. However, in general, the concrete floor surface (c) has some unevenness, and the bottom surface is not always horizontal due to the dimensional error of the talki (d). In such a state, when the conventional floor board support (a) is placed on the concrete floor surface (c) to support the talc (d), the square base (ch ) Causes one-sided contact with the lower surface of the talc.

[0006]

As described above, the conventional floor board supports have the above-mentioned problems. The problems to be solved by the present invention are these problems, and provide a top plate of a floor plate support tool which stably supports a floor plate without causing a one-sided contact of a square base supporting the talc.

[0007]

The top plate of the floor plate support according to the present invention is attached to the upper end of the plate holder, and engages with the hole provided at the center of the pedestal integrally formed on the upper end of the plate holder. You can do it. A bearing curved surface is formed on the upper surface of the central portion of the pedestal, and a curved axial surface is formed on the lower surface of the central portion of the top plate. The shaft surface rests on the bearing surface and is supported, and since the curved surfaces are in contact with each other, the direction can be changed.

A plurality of claws project downward at the center of the top plate, and the claws can be fitted in the center holes of the pedestal and locked so as not to come off. A wooden square base is attached to the top plate as in the conventional case, and the plate holder can be raised to abut the lower surface of the talc to support the talc. Here, the concrete structure of the floor board support for raising the plate holder is not limited.

By the way, the top plate can be tilted with respect to the pedestal of the plate holder, and the wooden rectangular base is brought into contact with the lower surface of the talc on the entire surface without a single contact.
That is, even if the concrete floor surface is tilted and erected due to swelling, or even if the lower surface of the talc is not horizontal, the talque can be intimately contacted with the lower surface of the talc and entirely contact. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an embodiment showing a floor board support provided with a top plate according to the present invention, in which 1 is a support base,
2 is a plate holder, 3 is an adjuster screw,
4 is an insert nut, 5 is a lock nut, and 6 is a top plate of the present invention. The support base 1 stands on the concrete floor surface, the lower surface 7 is adhered with an adhesive so as not to be displaced, and the wooden rectangular base 8 attached to the upper end of the top plate 6 is as shown in FIG. It can be supported by touching the lower surface of the talc. Here, the mounting structure of the rectangular base 8 is free.

The plate holder 2 having the top plate 6 attached to the upper end can be expanded and contracted in the vertical direction, so that a spline is formed on the outer periphery of the plate holder 2, and this spline is fitted into the spline hole of the adjuster screw 3. ing. As shown in FIG. 2 when the plate holder 2 is fitted in the spline hole of the adjuster screw 3, (a) shows the adjuster screw 3 when the plate holder 2 is in a free state.
It can be expanded and contracted by fitting it into the spline hole.

In (b), the plate holder 2 is locked and cannot be expanded or contracted. That is, small tooth profiles 16, 16 ... Are formed at equal intervals on the spline projection 15 of the plate holder 2, and tooth profiles 18, 18 ... Are also provided at the same pitch on the projection 17 of the spline hole. Therefore, when the plate holder 2 is rotated from the state of (a) to the state of (b), both tooth shapes 16 and 18 are engaged with each other and locked, the plate holder 2 cannot be expanded and contracted, and it does not fall. .

Therefore, the plate holder 2 can be stretched in the free state (a) so that the upper rectangular support 8 can be brought into contact with or brought close to the lower surface of the talc. This can be quickly operated by lifting the plate holder 2 and stretching it so that it does not fall when it comes into contact (b).
Rotate as shown to lock. After the rectangular base 8 contacts the lower surface of the talc, the adjuster screw 3 is rotated to finely adjust the height of the plate holder 2 so that there is no gap between the lower surface of the talc and the rectangular base 8.

A screw 19 is formed on the outer periphery of the adjuster screw 3, and the screw 19 is screwed into the insert nut 4. Insert nut 4 is support base 1
It is fitted in the seat formed at the upper end of the through hole 9 provided at the center of the. Therefore, when the adjuster screw 3 is rotated, the plate holder 2 can be lifted as it is without rotating, and the rectangular base 8 can be brought into contact with the lower surface of the talc without changing its direction.

By the way, a pedestal 10 is integrally formed on the upper end of the plate holder 2 as shown in FIG.
A hole 11 is provided at the center of the. Then, the top plate 6 is attached to the hole 11, but the top plate 6 is attached so as to change its levelness without being fixed. Therefore, a bearing surface 12 formed of a curved surface is formed around the hole 11, and the bearing surface 12 is in contact with and supported by the shaft surface of the top plate 6.

FIG. 4 shows the top plate 6,
Four tabs 13, 13 ... Are provided on the lower side of the disk-shaped top plate 6, and a curved shaft surface 14 is formed around the tabs 13, 13. The top plate 6 is placed on the pedestal 10 as shown in FIG. In this case, the shaft surface 14 contacts the bearing surface 12 of the pedestal 10, and the claws 13, 13 ... Can be fitted in the holes 11 and locked so as not to come off. Four claws 13,
13 can be flexibly deformed and fitted into the hole 11.

By mounting the curved shaft surface 14 on the concavely curved bearing surface 12, the top plate 6 can be positioned at the center of the plate holder 2 and can slide in any direction along the bearing surface 12. To allow, the top plate 6 can be tilted. Therefore,
The rectangular base 8 attached to the top plate 6 is also inclined in the same manner, and when the floor board support is arranged to support the talc,
The bottom surface of the talc is in contact with the entire surface with a proper inclination without uneven contact.

By the way, the top plate 6 of the present invention is not limited to the form of the floor plate support, and can be attached as a top plate (g) of the adjusting screw (e) of the conventional floor plate support, for example. . As described above, the top plate of the present invention is attached to the pedestal of the plate holder, and the following effects can be obtained.

[0019]

The top plate according to the present invention is attached to the pedestal of the plate holder. That is, a tab is fitted and locked in a hole provided in the center of the pedestal, and the curved shaft surface of the top plate is placed on the bearing surface formed by curving around the hole. Therefore, the upper surface of the top plate is not a surface fixed perpendicularly to the plate holder but can be inclined.

Even if the concrete floor surface on which the floor board support is placed cannot stand upright due to undulations, or even if the bottom surface is not horizontal due to the dimensional error of the talc, the top The square base attached to the plate fits the bottom surface of the talc and hits the entire surface, never one-sided. That is, since the entire surface of the lower surface of the talc can be contacted and supported, the floor board and the talc can be stably supported, which is a great effect in terms of vibration and soundproofing.
