Description

[Detailed Description of the Invention] The present invention relates to an anti-vibration support device for reinforced concrete floors, housing complexes, etc.

Generally, this type of vibration-proof support device for a floor is installed at a plurality of locations on a floor panel, and is used to adjust the horizontal level of the floor panel and construct a floor by laying a large number of floor panels.

Conventionally, as shown in FIG. 3, a conventional floor support device includes a pedestal 7 equipped with anti-vibration rubber 6 placed on a floor slab 4, a bolt 8 vertically integrated into the pedestal 7, and an upper end of the bolt 8. A nut 9 fitted into a through hole 51 of the floor panel 5 is screwed into the part, and the horizontal level of the floor panel 5 is adjusted by rotating the bolt 8.

However, with such a conventional support device, it takes time and effort to screw the bolt 8 into the nut 9 attached to the floor panel 5, resulting in poor workability, and the anti-vibration effect can only be expected from the anti-vibration rubber 6 at the lower end of the bolt 8. Therefore, there is a drawback that the anti-vibration effect is not sufficient.

In view of these conventional drawbacks, the present inventor has made extensive efforts to provide a vibration-proof support device for a floor that eliminates the above-mentioned drawbacks.

The present invention will be described below with reference to the drawings.

In the drawings, reference numeral 1 denotes a bolt, which has a screw 13 screwed into its lower end, a flanged seat 11 provided a predetermined distance below the upper end, and which engages the end of the bolt 1 above the flanged seat 11. A stop portion 12 is provided.
The brim-shaped seat 11 may be circular, rectangular, oval, etc., but is not particularly limited. The locking stepped portion 12 is formed by recessing the outer periphery of the upper end of the bolt 1 to have a small diameter. or,
The upper end surface of the bolt 1 is provided with a recess into which a screwdriver is locked.

2 is a leg member, and a pedestal 22 has a female thread 23 on a vibration-proof elastic material 21 made of rubber or synthetic resin.
is provided. Moreover, the pedestal 2 of the vibration-proof elastic material 21
An insertion hole for the bolt 1 is provided in a portion corresponding to the female thread 23 of No. 2.

Reference numeral 3 denotes a receiving member, which has a plate shape made of anti-vibration spring steel. The receiving member 3 has a bolt insertion hole 31 formed approximately in the center thereof, and the edge of the bolt insertion hole 31 is raised upward to provide a claw 32 as shown in FIG. A plurality of claws 32 are usually provided and have rebound resilience.

4 is a floor slab, 5 is a floor panel, and 51 is a through hole bored in the floor panel 5.

Therefore, in the vibration isolating support device of the present invention, the leg member 2 is placed on the floor slab 4 as shown in FIG. is vertical. Further, the upper end of the bolt 1 is fitted into the bolt insertion hole 31 of the receiving member 3 attached to the lower surface of the floor panel 5 in correspondence with the through hole 51 of the floor panel 5, and is received by the flanged seat 11 of the bolt 1. A member 3 is supported. At this time, the claw 32 of the receiving member 3 is locked to the locking stepped portion 12 of the bolt 1 due to its repulsive elasticity. Also, when adjusting the horizontal level of the floor panel 5,
The bolt 1 may be rotated using a screwdriver through the through hole 51.

As detailed above, in the support device of the present invention, the receiving member attached to the lower surface of the floor panel is fitted into the bolt,
Since the claw on the edge of the bolt insertion hole is locked to the locking step of the bolt due to rebound resilience, both can be attached by simply driving the bolt into the receiving member, improving work efficiency. .

In addition, the receiving member is made of anti-vibration spring steel, and the claws of the receiving member are locked to the locking steps of the bolts due to rebound resilience, so vibrations from the floor panel are weakened by the receiving member and transmitted to the bolts. The vibration-proofing effect can be improved together with the vibration-proofing effect of the leg member at the lower end of the bolt.

Furthermore, since the receiving member is rotatably locked to the locking step of the bolt by the repulsive elasticity of the claw, there is no problem in turning the bolt to adjust the height after installing the floor panel on the floor slab. do not have.
