[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor pan supporting structure in a unit room such as a unit bathroom, and more particularly to a vibration isolating supporting structure for a floor pan.

[0002]

2. Description of the Related Art Japanese Patent Application No. 1-262828 discloses a conventional technique similar to the present invention. As shown in FIG. 3, a schematic diagram of the floor pan vibration isolating support structure according to the same issue is shown in FIG. 3 in the installation structure of a floor pan 4 supported by a plurality of support legs 2 on an installation floor surface 1 of a building frame. An anti-vibration rubber 3 is provided in the middle of the leg 2.

[0003]

Since the floor pan is usually provided with a slope for drainage, the required height of the support leg also depends on the position where it is attached. In addition, since the height of the supporting legs differs depending on the unit bathroom model, when considering that it can be attached to all things, supporting legs with anti-vibration rubbers of various heights are required. There are many negative aspects in management.

[0004] Further, in the above-mentioned conventional anti-vibration support structure for a floor pan, there is a problem that the floor pan swings greatly.

[0005] That is, in general, in the case of a round rubber anti-vibration rubber, the spring constant in the horizontal direction is significantly smaller than the spring constant in the vertical direction. Incidentally, in the rubber 3 of FIG. 3, the vertical direction is about 600 kgf / cm and the horizontal direction is about 90 kgf / cm.

When such a rubber is used, the lateral sway becomes large due to a small spring constant in the horizontal direction. It is conceivable to increase the rubber hardness or the like in order to increase the spring constant in the horizontal direction so as not to cause lateral sway, but increasing the rubber hardness in this way is a negative factor in the vibration isolation effect.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned conventional problems and to provide a vibration-damping support structure for floor pans, which requires a small number of specially-shaped vibration-damping members and is easy to construct.

[0008]

According to a first aspect of the present invention, there is provided a floor pan anti-vibration support structure in which a floor pan is supported by a plurality of support legs. The vibration isolating member includes a rubber block, and a cap made of a high-rigidity material with a closed bottom and a bottom covered by the rubber block. A gap is provided between the surface and the rubber block such that the outer peripheral surface of the rubber block contacts the inner peripheral surface of the cap when the floor pan vibrates in the lateral direction. Things.

According to a second aspect of the present invention, in the vibration isolating support structure for a floor pan, the lower end surface of the support leg and the top surface of the cap are adhered with an adhesive. The peripheral portion is provided with a convex portion for preventing the adhesive from flowing out.

[0010]

According to the vibration isolating support structure of the floor pan of the present invention, the floor pan is supported by the vibration isolating member composed of the rubber block and the cap. To make the floor pan level (installation height) different, change the length of the support legs. Bolts are usually used for the support legs, and the floor pan level can be freely set by using bolts having different lengths. This bolt can be easily prepared in any length by simply cutting it.

In the vibration isolating support structure of the floor pan according to the present invention, the vibration isolating member comprises a rubber block and a cap mounted on the rubber block as described above. There is a predetermined gap between the inner peripheral surface and the outer peripheral surface of the rubber block. When the floor pan sways, the inner peripheral surface of the cap and the outer peripheral surface of the rubber block come into contact with each other, thereby reducing the lateral sway of the floor pan.

In the vibration isolating support structure for a floor pan according to the second aspect, since the supporting leg and the vibration isolating member are bonded, the supporting leg is firmly fixed to the vibration isolating member. In addition, since the convex portion is provided around the peripheral portion of the cap, the support leg can be easily bonded to the vibration isolating member without dripping of the adhesive.

FIG. 1 is a longitudinal sectional view showing the overall configuration of an embodiment.
FIG. 2 is a longitudinal sectional view of the vibration isolating member.

The floor pan 4 is supported on the floor 1 via support legs 5 and vibration isolating members 6. The vibration isolating member 6 includes a cylindrical rubber block 7 and a metal cap 8 having a closed bottom and a bottom and mounted on the rubber block 7. Is provided with a convex portion 9. The support leg 5 is made of a long bolt, and is adhered to the cap 8 with an adhesive 10. There is a predetermined gap between the inner peripheral surface of the cap 8 (with rubber coating) and the outer peripheral surface of the rubber block 7.

In the present embodiment, a metal plate 11 is adhered to the bottom surface of the rubber block 7.

In the floor pan vibration isolating support structure thus configured, the floor pan 4 is supported by a vibration isolating member 6 comprising a rubber block 7 and a cap 8.
In order to make the levels different, bolts having different lengths may be used as the bolts constituting the support leg 5. This bolt can be easily prepared in any length by simply cutting it.

In the vibration isolating support structure of the floor pan of the present embodiment, a vibration isolating member 6 comprising a rubber block 7 and a cap 8 mounted on the rubber block is used.
There is a predetermined gap between the inner peripheral surface of the cap 8 and the outer peripheral surface of the rubber block 7. When the floor pan 4 sways, the inner peripheral surface of the cap 8 and the outer peripheral surface of the rubber block 7 come into contact with each other, whereby the horizontal sway of the floor pan 4 is reduced.

The spring constant of the rubber block 7 used in this embodiment is 600 kgf / cm in the vertical direction and 90 kg in the horizontal direction.
kgf / cm, which is the same as the conventional one, but the rubber constant in the horizontal direction after the outer peripheral surface of the rubber block 7 hits the inner peripheral surface of the cap 8 is as extremely large as 190 kgf / cm. As a result, the floor pan 4 could be sufficiently prevented from laterally shaking.

Further, in the anti-vibration support structure of the floor pan of the present embodiment, since the support leg 5 and the cap 8 of the anti-vibration member 6 are bonded, the support leg 5 is It is fixed firmly. In addition, since the protrusion 9 is provided around the periphery of the cap 8, the adhesive 10 does not droop and the support leg 5 does not drop.
Can be easily bonded to the vibration isolating member 6.

When bonding the support leg 5 to the vibration isolating member 6, it is preferable to apply an adhesive 10 to the upper surface of the cap 8 and press the support leg 5 from above. In this case, the support leg 5 is fixed to the floor pan 4 in advance, and the vibration isolating member 6 is arranged at a predetermined position on the floor surface 1. It is preferable to bond with the vibration isolating member 6.

The floor surface 1 in the above embodiment may be a board surface such as a concrete floor surface or a laterally drawn member such as a joist. In the present embodiment, the plate 11 is adhered to the bottom surface of the rubber block 7 to increase the entire bottom area of the vibration isolator 6. Therefore, the floor pan 4 can be stably installed on the joist made of wood via the vibration isolating member 6 and the support leg 5. That is, even if a large weight is added to the vibration isolation member 6, the plate 11 does not bite into the wood.
