Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a noise reduction ventilation structure provided in, for example, a room of a collective housing and a construction method for this noise reduction ventilation structure.

Conventionally, sashes used as windows on the outer wall of living rooms in buildings (for example, sashes defined as type 1 opening component materials defined in JISA0005) conform to the sound insulation grade defined in JISA4706. The sound insulation grade has four grades from T-1 to T-4. For example, T-4 requires sound insulation measures for the most noisy environment. Moreover, the above sound insulation grade may be applied not only to the sash but also to the surrounding structure to which the sash is attached.

For example, a soundproof hood or a duct-inserted sound deadening member made of foam material may be attached to the air supply port of a living room that penetrates the outer wall on the veranda side, but these alone do not provide sound insulation performance equal to or greater than T-4. Since it is difficult to secure such a space, a sound deadening box and a sound deadening flexible are installed on the interior side of the outer wall to obtain the desired sound deadening effect and ventilation effect. However, as the sound deadening box and sound deadening flexible protrude from the outer wall to the living room side, the distance between the outer wall and the inner wall to cover them (so-called "addition") increases, so there is a concern that the living room will become narrower. Ta.

On the other hand, Patent Literature 1 discloses a device that uses a curtain box to obtain not only a desired ventilation effect but also a silencing effect. Specifically, the above device includes an air flow path extending in the length direction of the curtain box, an outside air intake port that communicates the air flow path with the outside air, and an air outlet that communicates the air path with the interior of the room. , and since a porous humidity control material is installed in the air flow path, it absorbs a certain amount of outside noise while reducing the humidity of the air introduced into the room.

JP 2018-4231 A

In some buildings, in consideration of heat insulation, soundproofing, and air permeability, there are structures that have inner walls from the outer wall through additional walls (so-called double wall structures), and there are also structures that do not have additional walls and are used as finishing materials. Some structures have inner walls and some have only outer walls. In any structure, if an air supply port is formed on the wall surface to ventilate the room and a sound insulation performance of T-4 or higher is secured, a sound deadening box and a sound deadening flexible are effective, but such a device is not used. The location and range of storage should be considered.

Therefore, the inventors came up with the idea of installing a device that realizes silencing and ventilation by using the incidental equipment of the living room such as the curtain box described in Patent Document 1 and the basic structure of the living room such as the hanging ceiling. there was. However, if the space inside the curtain box itself is ventilated as in Patent Document 1, the structure for realizing ventilation and noise reduction becomes complicated. In other words, the feature of the inventors' idea is to obtain the desired effect from a device that realizes silencing and ventilation without reducing the area of the living room by effectively utilizing the ancillary equipment and the basic structure of the living room.

Therefore, the object of the present invention is to effectively utilize the ancillary equipment and basic structure of a living room to install a conventional device that realizes silencing and ventilation, and to avoid narrowing the area of the living room. To provide a construction method for
