CONSTITUTION:A sleeper 3 is mounted on the part of the joist 1 in the floor of the upper floor through a shock absorbing rubber 8. A strap 5 is mounted on the part of a cradling 4 in the ceiling of the lower floor. A member 7 having a rubber material 73 adhered between brackets 71, 72 is mounted on the strap 5 and the sleeper 3 through the brackets 71, 72. Further, a shock absorbing rubber 9 is interposed between a floor board 2 and the joist 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling support structure for cutting off sound and vibration caused by a shock transmitted from a floor above a floor to a ceiling below a wooden house.

[0002]

2. Description of the Related Art In a ceiling support structure of a wooden house in which a Daihiki attached to a floor above the floor and a tie attached to a rim of a ceiling below the floor are connected to each other, they are added to the floor. Sounds and vibrations due to impacts are easily transmitted to the ceiling below, especially when a flooring type floor with a wooden floor board pasted on joists is used, the large noises and vibrations due to the impacts on the floors It is transmitted to the ceiling and has become a living environment problem.

For this reason, conventionally, the floor of wood is directly attached to the joists and has a special structure for absorbing shock, so that the floor itself is soundproofed and vibration-proofed.

[0004]

The problem to be solved is that the sound and vibration due to the impact applied to the floor can be obtained only by making the wooden floor board directly attached on the joists have a special structure for absorbing shock. The effect is not sufficient to cut off the sound, and sound and vibration leak to the ceiling downstairs.

Further, the members constituting the floor have contractibility, and dimensional deviation is inevitable over time, and the deviation causes the floor to squeak and produce a sound each time a person steps on the floor. It is not possible to prevent the generation of sound due to the squeaking of the floor itself by just using a special structure for shock absorption, and the squeaking sound of the floor is transmitted to the ceiling below.

[0006]

DISCLOSURE OF THE INVENTION The present invention relates to a wooden house in which a large haul attached to a joist portion of a floor above the floor and a lumber attached to an edge portion of a ceiling below the floor are connected to each other. In the ceiling support structure, in order to block the sound and vibration due to the impact applied to the floor and the squeaking sound of the floor itself at the part of the ceiling support structure, the two are pulled by the rubber shearing force between the Daihiki and the tree ties. The feature is that a member for connection is provided.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A ceiling support structure according to the present invention is shown in FIG.
As shown in FIG. 2 and FIG. 2, the timber house 3 is attached to the joist 3 attached to the joist 1 on the floor above and the hanging tree 5 attached to the nose 4 in the ceiling below the floor. In the ceiling support structure of No. 7, a member 7 for connecting the large pull 3 and the lumber 5 to each other by the shearing force of rubber.
Is provided.

As a floor on the upper floor, a wooden floor board 2 is attached on a joist 1. Further, as a downstairs ceiling, a ceiling board 6 is attached to the field edge 4.

The member 7 has a rubber material 73 adhered between the fittings 71 and 72.
1, 72 are mounted between the side surface of the joist 1 and the side surface of the fishing lumber 5 by screwing, and the joist 1 and the fishing lumber 5 are connected by the shearing force of the rubber material 73.

However, in order to cut off the sound and vibration transmitted from the floor above the floor to the ceiling below the ceiling through the ceiling support structure, it is necessary to make the natural frequency of the spring system in the ceiling support structure as low as possible. Since the spring constant of the rubber member 73 in the member 7 in the shearing direction is as small as about a fraction of that in the compressing direction, the member 7 effectively cuts off the sound and vibration transmitted from the floor above the floor to the ceiling below. It

By providing the member 7 in the ceiling support structure, the sound transmitted through the ceiling support structure can be reduced by about 20 dB as compared with the case where it is not provided, and the sound is transmitted from the floor above the floor to the ceiling below. It was confirmed by experiments that the sound was reduced to about 1/3.

A cushioning rubber 8 is interposed between the joist 1 and the haul 3.

The cushioning rubber 8 is a plate-shaped cushioning portion 81.
It is formed in a T-shape in cross section, and is formed by inserting the leg portion 82 into the groove portion 31 formed in the haul 3.

A cushioning rubber 9 is interposed between the floor board 2 and the joist 1.

The cushioning rubber 9 is a plate-like cushioning portion 91.
The leg portion 92 is formed in a T-shape in cross section, and is attached by inserting the leg portion 92 into the groove portion 11 formed in the joist 1.

However, the sound and vibration due to the impact applied to the floor above the floor, and the squeaking noise of the floor itself are effectively blocked by the cushioning rubbers 8 and 9.

Further, by using a sound insulation board as the ceiling board 6, the sound insulation effect is further improved.

[0018]

As described above, in the ceiling support structure according to the present invention, when connecting the Daihiki attached to the joist portion of the floor above the floor and the hanging tree attached to the edge portion of the ceiling below the floor. , A member that connects them by the shearing force of rubber is provided between the Daihiki and the fishing tree, and the sound and vibration transmitted from the floor above the floor to the ceiling below the floor through the ceiling support structure is effective by that member. It has the advantage that it can be cut off.
