DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soundproof structure capable of effectively suppressing vibration propagating from an upper floor to a lower floor in a wooden house.

[0002]

2. Description of the Related Art Noise (shock sound) generated in a house includes:
For example, a heavy floor impact sound due to the impact of heavy and soft objects such as a child jumping or running around, or a light floor impact due to the impact of a relatively light and hard object due to high heels walking, moving furniture or the sound of a spoon falling from a table, etc. There are air and sound propagating in the air, such as sound and television sound.

In a house, vibrations due to noise in the upper floor room are easily transmitted to the lower floor room. To suppress the vibration, the ceiling structure of the lower floor room is conventionally reduced by using various means. It is common practice to shield them from.

For example, in the technology disclosed in Japanese Patent Application Laid-Open No. 9-4202 (first known example), the rigidity of the floor structure of the upper floor room is increased to suppress the generation of impact itself, and the vibration absorption floor surface of the upper floor room is further increased. In combination with the sound-insulating ceiling of the lower-floor room, it is possible to reduce the impact sound generated in the upper-floor room to the lower-floor room.

In the technique disclosed in Japanese Patent Application Laid-Open No. 8-68145 (second known example), a buffer member is filled in a runner fixed to a lower flange of a beam supporting a floor structure of an upper floor room.
By attaching the vertical rail of the partition wall via the buffer member, vibration of the beam is absorbed by the buffer member and is not transmitted to the partition wall, so that sound insulation between the upper and lower floor rooms can be achieved.

[0006]

However, the first known example described above has a problem that the rigidity of the floor structure of the upper floor is increased to suppress the generation of impact itself, so that the structure is excessively designed and the cost is increased. In addition, although there is a soundproofing effect against heavy floor impact sounds, there is a problem that a sufficient soundproofing effect cannot be obtained against lightweight floor impact sounds.

In the second known example, a buffer member is filled and interposed between a runner fixed to a lower flange of a beam and a vertical bar (stud) of a partition wall, so that the number of parts such as a runner and a buffer member is reduced. However, there is a problem that the cost increases and the operation of filling the cushioning member takes time.

In the case of a concrete house,
Since the propagation of vibration is mostly from the ceiling, it is only necessary to take measures to shield the ceiling of the lower floor room, but in the case of a wooden house, there is a path of sound propagation from the wall other than the ceiling, and the experiment conducted by the applicant has According to the report, the main part of the propagation from this wall was found to be due to the structural materials that make up the wall, that is, pillars and studs at the corners of the room. I understood.

The present invention has been made to solve the above problems, and
The purpose is to reduce the number of parts and the construction work with a simple structure, and a wooden house that can exhibit a soundproof effect against any of heavy floor impact noise, lightweight floor impact noise and air propagation noise. In this regard, the soundproof structure of the present invention is provided.

[0010]

According to the present invention, there is provided a soundproof structure for a wooden house according to the present invention, comprising: a soundproof structure between an upper-floor room and a lower-floor room in a wooden house; The peripheral portion is supported by the peripheral portion of the lower floor room, and a plurality of intermediate portions of the ceiling portion are supported by the floor structure of the upper floor room via vibration isolating means, and are disposed at the peripheral portion of the lower floor room. The upper portions of the plurality of studs were connected to each other with cross members, and the ends of the cross members were connected to the column members arranged around the lower floor room without making the cross members contact the floor structure of the upper floor room. It is characterized by the following.

[0011] In the above structure, impact vibration and air vibration input to the floor structure of the upper floor room propagate through the floor structure and are radiated as sound from the ceiling and walls of the lower floor room. Most of the vibration propagates vertically below the floor structure of the upper floor room,
Since the middle part of the ceiling of the lower floor room is connected to the floor structure of the upper floor room via the vibration isolating means, vibration from the upper floor room is moved from the floor of the upper floor room to the ceiling of the lower floor room. Radiated sound generated by directly propagating to is sufficiently suppressed.

In each of the above-mentioned known examples, the vibration propagating from the peripheral portion of the floor structure in the upper floor room propagates downward from the column material in the upper floor room via the column material in the lower floor room, and the floor. It is roughly classified into a path that propagates downward through the studs of the lower-floor room connected to the beams. By connecting the end of the cross member connected to the column to the column located around the lower floor room without contacting the floor structure of the upper floor room, vibration does not propagate directly from the floor beam to the stud, Since the path propagates from the member to each stud via the cross member, the propagation distance is increased, and the vibration is effectively attenuated during the propagation, so that the sound radiated from the wall of the lower floor can be reduced.
