Description

Description: BACKGROUND OF THE INVENTION The present invention relates to a support leg of a panel board for flooring, and more particularly, to a flooring for converting a floor such as a mansion to a plate material, the panel board is formed of a concrete floor structure. The present invention relates to a support leg of a flooring panel board for supporting the body.

[Conventional technology]

Recently, flooring for changing floors such as mansions from carpets to boards has been increasingly used.
This is due to the uncomfortable feeling of laying carpets directly on concrete floor structures, namely the transmission of noise downstairs,
The floor is stiff against the feet, making it unsuitable for dwelling. It is also prone to mites and has no cleanliness. This is because there is a tendency to solve disadvantages such as troublesome cleaning.

Such flooring is performed by extending a floor using a plate material on an existing concrete floor structure, and is generally performed by adopting a structure as shown in FIG.

That is, a plurality of support legs are erected to support the flooring panel board with respect to the existing concrete floor structure.

Generally, as shown in FIG. 1, the support legs screw a support bolt 3 to a panel board receiver 2 and rotate the support bolt 3 from the upper surface of the panel board 2 to form a concrete floor structure. A cushion rubber 4 is fitted to the lower end of the support bolt 3 so as to absorb vibration such as walking applied to the panel board 1;
Thus, the transmission of vibration to the downstairs can be prevented.

In addition, Japanese Utility Model Laid-Open No. 55-109732 discloses that by providing a rubber elastic base material and a universal joint, the floor surface can be adjusted horizontally without considering the inclination of the base surface, and a support exhibiting an anti-vibration function is provided. An apparatus is disclosed. Furthermore, 48-8663
No. 0 discloses a configuration in which a column can be adjusted by penetrating a column through a through hole of a spherical projection and clamping the column with a nut.

[Problems to be solved by the invention]

However, the permissible error of concrete casting is recognized relatively large, and therefore, the surface of the concrete floor structure is in a state of relatively severe irregularities.

For this reason, when the panel boards are sequentially arranged from the corner of the room, it is possible to avoid positioning the cushion rubber 4 in a state in which the cushion rubber 4 partially rides on the unevenness of the concrete among the support legs (normally 4 to 5). Not often happens. The inclination of the panel board 1 due to such unevenness is corrected horizontally by turning the support bolt 3 of the support leg to adjust the length and balancing the height with the other support legs. When the bolt 3 is adjusted, the unevenness of the concrete is temporarily absorbed by the local portion of the cushion rubber 4 that comes into contact (the rubber is locally compressed).

That is, since the support bolt 3 itself is rigid and is connected to the panel board as a rigid body, it is necessary to support a part of the panel board 1 while only the cushion rubber 4 is in a distorted deformation state. I can't get it.

However, such a cushion rubber 4 deteriorates with time and lowers its elasticity. Further, since vibrations are applied to cause cracks, the cushion rubber 4 is further deformed into a strain as described above, and is further increased when a load is locally applied. Deterioration and crack generation increase.

As a result, the cushion rubber 4 contacting the irregularities
Of the panel board 1 is collapsed, and a gap is generated between the panel board 1 and the concrete floor surface F. The efficiency of absorbing vibration when walking or placing an object on the panel board 1 is deteriorated, and a large sink occurs when a load is applied. At the same time, there is a problem that the cushioning effect for the feet is deteriorated.

Further, according to the contents disclosed in Japanese Utility Model Application Laid-Open No. 55-109732, when the base surface is distorted more than horizontal, the floor surface is received in a state where the universal joint is largely bent in the shape of "ku". And does not have a sufficient supporting force on the panel board surface. Therefore, if vibration or pressure is applied to the panel board surface for a long period of time, even if the panel board is adjusted horizontally at the time of construction, over time, the degree of bending of the ukule It becomes even larger and eventually loses its supporting force, and the panel board becomes very unstable, so that the function as the flooring cannot be sufficiently exhibited.

Further, according to the contents disclosed in Japanese Utility Model Laid-Open Publication No. 48-86630, if the nut is excessively tightened, there is no flexibility in changing the angle of the support column, and floating occurs at a portion where the base surface is not horizontal, and the nut is tightened. If it is weak, the floating will be eliminated, but it will be more easily bent by long-term vibration or pressure, and will exhibit the same drawbacks as those disclosed in Japanese Utility Model Laid-Open No. 55-109732. In other words, although the occurrence of floating can be prevented for the time being, there is a disadvantage that the degree of tightening of the nut is difficult.

An object of the present invention is to adapt to the irregularities on the surface of the concrete floor structure, to sufficiently exert the function of the cushion rubber, and to maintain the vibration absorbing effect for as long as possible. .

[Means for solving the problem]

The present invention employs the following configuration to achieve the above object. First, the present invention provides a flooring panel board in which a supporting bolt is screwed into a panel board receiver for supporting the flooring panel board so that the height can be adjusted, and a cushion rubber is provided at a lower end of the supporting bolt. A support leg, wherein the support bolt includes a screw portion screwed into the panel board receiver and a holding portion attached to the cushion rubber, and a universal joint is interposed between the screw portion and the holding portion. It is premised on supporting legs for paneling for flooring.

In the support leg, the present invention provides the universal joint,
A spherical part is formed on the screw part side and a bowl part is formed on the holding part side, and a rotation restricting part for restricting the rotation of the bowl part and the spherical part to a predetermined angle is provided.

According to the above-mentioned configuration, floating does not easily occur at the time of construction, the labor required for the construction is reduced, and a stable supporting force can be maintained for a long period of time.

[Action]

With the above configuration, as shown in FIG. 2, even when the panel board 1 must be supported at a position where the supporting legs of the panel board 1 ride on the convex portion f1 of the concrete floor F, the cushion rubber 4 is supported by the convex portion f1. When you get on,
The holding portion 3b is inclined by the universal joint 5, and the cushion rubber 4 comes into contact with both the convex portion f1 and the flat portion f2 to support the load evenly.
