Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a support member having a mounting surface for placing and supporting the corner portions of four panel-shaped floor members in a butt state, and a boss portion formed with a female threaded hole; a male threaded member screwed into the female threaded hole and having an engagement portion for a rotation operating tool on the upper end side; and a pedestal that rotatably supports the lower end side, and the male threaded member is screwed by operating a rotary operating tool from the upper surface side of the mounting surface of the supporting member, and the supporting member and the structural floor slab are connected to each other. The present invention relates to a floating floor support device configured to adjust the height between the floating floors.

Conventionally, as shown in FIG. 10, in order to support the corners of four panel-shaped floor members P in a butt state, a support device A' is provided at each corner of the floor members P. However, in this case, one support device A' is used for each corner of each floor member, so the number of support devices A' used for the entire floating floor is very large, which is not economical or workable. I was at a disadvantage.

On the other hand, in the case where the upper end support member is used to commonly place and support four floor members abutting each other as described above, a height adjustment tool is required for each common support member. Since only one is attached, it is very economical, and the height can be adjusted from above while the panel-shaped floor member is placed and supported on the support member, so it has the advantage of being advantageous in terms of workability.

However, in the above-mentioned floating floor support device, the four floor members are placed on one support member with their corners abutted, and then the height is adjusted by screwing the male threaded member from the top of the floor member. The following problems arose due to the fact that

Since the upper surface of the support member and the lower surface of the floor member are flat, relative slippage tends to occur in the horizontal direction, and as a result, relative positioning of each of the four floor members takes time and effort.

There is a strong tendency for adjacent floor members to be placed in contact with each other over the entire length of their edges, and in this case, walking vibrations cause relative rubbing of the contact edges, causing squeaks and noise, which impedes livability. do.

When screwing the male threaded member to adjust the height, the support member tends to rotate with it, so it is recommended to fix the floor member and the support member before adjusting the height to prevent the floor members from shifting. It is necessary to prevent the support member from rotating along with the support member, and if the floor member fixed to the support member is locally moved up and down, an unreasonable force is applied to the fixed portion between the floor member and the support member. Therefore, when a floor member and a support member are fixed with nails, for example, the nails tend to loosen and bend, and when fixed with adhesive, the height must be increased until both are completely adhesively fixed. Not only is adjustment impossible, but there is a risk that the adhesive may come off during height adjustment, causing the floor member to jump up from the support member.

It is an object of the present invention to solve such problems by adding only an extremely simple configuration, thereby making it possible to fully exhibit the above-mentioned advantages.

The characteristic structure of the present invention for achieving the above object is the above-mentioned floating floor support device, in which a support member is provided with a support member on a mounting surface of the support member between adjacent opposing edges of the panel-like floor member. A protrusion is provided to intervene and regulate the relative positions of the four panel-shaped floor members while leaving a small gap between these opposing edges, and the boss is placed above the mounting surface. and the upper end surface of the boss portion and the upper end surface of the protrusion are located at a lower position than the upper surface of the panel-shaped floor member mounted and supported by the support member, This configuration provides the following effects.

That is, with respect to the protrusion attached to the support member,
If the corners of each floor member are placed on the support member with their respective edges in contact with each other, the relative positioning of each floor member can be easily determined. Since a small gap corresponding to the width of the protrusion inevitably appears, generation of creaking noise due to relative friction can be prevented and the comfort of living can be improved. and,
The boss part into which the male threaded member is screwed is made to protrude above the mounting surface of the support member to ensure sufficient tightening margin between the male threaded member and the boss part, so the boss part is projected below the mounting surface. Compared to the case where the boss only protrudes from the mounting surface to secure the tightening margin, the amount of downward protrusion of the boss part is smaller than the mounting surface, and by appropriately selecting the length of the male thread member, the mounting surface can be placed at a lower position. It can also be positioned to support a floor member.

In addition, since both the protrusion and the boss are sized so that their upper ends are lower than the upper surface of the floor member, the upper surface of the group of floor members may be covered with floor materials such as tatami mats or carpets, or any portions intervening between the floor materials. There is no problem in laying the two floor member groups.

Furthermore, the protrusion attached to the mounting surface of the support part has a function of preventing the support member 1 from rotating when the male threaded member is screwed forward for height adjustment by coming into contact with the floor member. Therefore, there is no need to fixedly connect the floor member and the supporting member before adjusting the height, and the floor member and the supporting member can be reliably fixed after the floor member is adjusted to a predetermined height position. can.

As described above, according to the present invention, it is possible to prevent squeak noise and to speed up and facilitate the work of placing floor members, even though the addition of a very simple structure such as attaching a protrusion to the support member is sufficient. ,as a whole,
It has now been possible to fully utilize the economical and workability advantages expected of the support device having the above-mentioned configuration.

Embodiments of the present invention will be described below based on the drawings.

As shown in Fig. 1, in order to support the four panel-shaped floor members P above the structural floor slab B in a horizontal position, the support member places and supports the four floor members P with their corners butted against each other. 1 and a height adjuster 3 with a vibration isolator 2 interposed between the support member 1 and the floor slab B is used. As shown, four floor members P are placed on the mounting surface of the support member 1 with their corners abutted.
The upper end of the protrusion 4 is placed and supported on the support member 1, and the protrusion 4 is capable of coming into contact with the adjacent opposing edges t, t of the opposing edges t, t while leaving a small gap between the opposing edges t, t. It is attached in a state lower than the upper surface of the floor members P, P. There are many types of shapes of this protrusion 4, as will be described later.

The vibration isolating material 2 includes a glass fiber aggregate of 150 to 800
It is preferable to compress and shape the material to a high density of about Kg/m ² and cover the entire surface with a rubber film, but it may also be made entirely of hard rubber.
