Description

本発明は、フード部の天板の上に弾性支持体を介して水滴受板が設けられた構造を備えた換気口端末部材等に関する。 The present invention relates to a ventilation port terminal member or the like having a structure in which a water droplet receiving plate is provided on a top plate of a hood portion via an elastic support.

集合住宅、ホテル、事務所ビル等の建物においては、換気設備の設置が義務付けられている。当該換気設備としては、居室に換気口が設置されて、居室の外壁にベントキャップ等と呼称される換気口端末部材が設置されることが多い。
当該換気口端末部材は、フード部が外壁面よりも外側に突出するように建物の上下階の外壁の換気孔にそれぞれ取付けられ、上下階の各換気口端末部材が、垂直線上に位置されることが多い。
当該建物においては、降雨等の後に、上階の換気口端末部材から水滴が落下して下階の換気口端末部材のフード部の天板の上に衝突した際に、水滴落下衝突音が生じ、当該水滴落下衝突音が固体伝播音として居室内に伝播する。
当該水滴落下衝突音の低下対策を施した換気口端末部材としては、例えば、フード部の天板の上に弾性支持体を介して水滴受板が設けられた構造のものが知られている（特許文献１参照）。 Ventilation equipment is obligatory in buildings such as apartment houses, hotels, and office buildings. As the ventilation equipment, a ventilation port is often installed in the living room, and a ventilation port terminal member called a vent cap or the like is often installed on the outer wall of the living room.
The ventilation port terminal members are attached to ventilation holes on the outer walls of the upper and lower floors of the building so that the hood portion projects outward from the outer wall surface, and each ventilation port terminal member on the upper and lower floors is positioned on a vertical line. Often.
In the building, when water droplets fall from the ventilation port terminal member on the upper floor and collide with the top plate of the hood part of the ventilation port terminal member on the lower floor after rainfall, etc., a water droplet drop collision sound is generated. , The water droplet falling collision sound propagates in the living room as a solid-borne sound.
As a ventilation port terminal member for which measures are taken to reduce the sound of falling water droplets, for example, a member having a structure in which a water droplet receiving plate is provided on a top plate of a hood portion via an elastic support is known ( See Patent Document 1).

しかしながら、特許文献１に開示された換気口端末部材では、フード部の天板の上に弾性支持体を介して水滴受板が設けられた構造であるため、弾性支持体のばねによる減衰効果によって水滴落下衝突時における低周波数帯域の音を低減させる効果が得られるが、水滴受板の表面に対する水滴落下衝突時における中高周波数帯域の音を低減させる効果が十分ではないという課題があった。
本願発明は、水滴受板の表面に対する水滴落下衝突時における中高周波数帯域の音を低減させる効果を向上させた換気口端末部材等を提供するものである。 However, the ventilation port terminal member disclosed in Patent Document 1 has a structure in which a water droplet receiving plate is provided on the top plate of the hood portion via an elastic support, and therefore, due to the damping effect of the spring of the elastic support. Although the effect of reducing the sound in the low frequency band at the time of the water droplet drop collision can be obtained, there is a problem that the effect of reducing the sound in the middle and high frequency band at the time of the water droplet drop collision with the surface of the water droplet receiving plate is not sufficient.
The present invention provides a ventilation port terminal member or the like having an improved effect of reducing sound in the middle and high frequency bands at the time of a water droplet drop collision with the surface of a water droplet receiving plate.

本発明に係る換気口端末部材は、建物の外壁に形成された換気孔に取付けられる換気口端末部材であって、建物の外壁面より建物の外側に突出するフード部と、フード部の天板の上に弾性支持体及び制振層を介して設けられた水滴受板とを備え、制振層は、水滴受板の水滴を受ける表面とは反対側の裏面と対向するように設けられた弾性を有した弾性板と、弾性板の裏面と対向するように設けられた支持板とを備え、水滴受板の裏面と弾性板の表面、弾性板の裏面と支持板の表面、支持板の裏面と弾性支持体の表面とがそれぞれ接触するように、これら水滴受板と弾性板と支持板と弾性支持体とが連結手段により連結されたことを特徴とするので、水滴受板の表面に対する水滴落下衝突時における中高周波数帯域の音を低減させる効果を向上させた換気口端末部材を提供できる。
また、本発明に係る建物は、上述した換気口端末部材のフード部及び水滴受板が外壁面よりも外側に突出するように当該換気口端末部材が外壁に設けられた建物であって、建物の上下階の外壁に設けられた各換気口端末部材の各水滴受板の表面が、垂直線上に位置されたことを特徴とするので、換気口端末部材の水滴受板の表面に対する水滴落下衝突時における中高周波数帯域の音を低減させる効果を向上させた建物を提供できる。 The ventilation port terminal member according to the present invention is a ventilation port terminal member attached to a ventilation hole formed in an outer wall of a building, and has a hood portion protruding from the outer wall surface of the building to the outside of the building and a top plate of the hood portion. An elastic support and a water droplet receiving plate provided via a vibration damping layer are provided on the surface, and the vibration damping layer is provided so as to face the back surface of the water droplet receiving plate opposite to the front surface of the water droplet receiving plate. It is provided with an elastic plate having elasticity and a support plate provided so as to face the back surface of the elastic plate. The water droplet receiving plate, the elastic plate, the supporting plate, and the elastic support are connected by a connecting means so that the back surface and the front surface of the elastic support are in contact with each other. It is possible to provide a ventilation port terminal member having an improved effect of reducing the sound in the middle and high frequency bands at the time of a water droplet drop collision.
Further, the building according to the present invention is a building in which the ventilation port terminal member is provided on the outer wall so that the hood portion and the water droplet receiving plate of the ventilation port terminal member described above project outward from the outer wall surface. The surface of each water drop receiving plate of each ventilation port terminal member provided on the outer wall of the upper and lower floors of the ventilation port terminal member is located on a vertical line.

図１乃至図３に示すように、フード部３は、四角形状の前板３１と、天板（上板）３２と、左側板３３と、右側板３４と、後板３５とを備えた直方体函状に形成されており、下部が開口された室外側通風孔３６に形成されて、かつ、後板３５を形成する四角形状の板の中央側が開口された室内側通風孔３７に形成され、当該室内側通風孔３７の孔縁側に筒部２の一端開口縁側が接続されている。即ち、筒部２が、フード部３の後板３５に接続されて当該後板３５の後方に延長するように設けられた構成となっている。筒部２は、例えば、円筒部に形成される。
即ち、フード部３は、換気口端末部材１が換気孔９２に取付けられることによって、下部の室外側通風孔３６、及び、室内側通風孔３７を介して、建物９０の内側から建物９０の外側に、又は、建物９０の外側から建物９０の内側に空気を流通させることが可能な構成となっている。
また、室外側通風孔３６、及び、室内側通風孔３７のうち、少なくとも、一方の通風孔は、防虫対策等のためにメッシュ孔やガラリ等により形成されている。 As shown in FIGS. 1 to 3, the hood portion 3 is a rectangular parallelepiped including a square front plate 31, a top plate (upper plate) 32, a left side plate 33, a right side plate 34, and a rear plate 35. It is formed in a box shape, is formed in an outdoor ventilation hole 36 having an open lower portion, and is formed in an indoor ventilation hole 37 having an open central side of a square plate forming the rear plate 35. One end opening edge side of the tubular portion 2 is connected to the hole edge side of the indoor ventilation hole 37. That is, the tubular portion 2 is connected to the rear plate 35 of the hood portion 3 and is provided so as to extend to the rear of the rear plate 35. The tubular portion 2 is formed in, for example, a cylindrical portion.
That is, in the hood portion 3, the ventilation port terminal member 1 is attached to the ventilation hole 92, so that the ventilation port terminal member 1 is attached to the ventilation hole 92 from the inside of the building 90 to the outside of the building 90 through the lower outdoor ventilation hole 36 and the indoor side ventilation hole 37. The structure is such that air can be circulated from the outside of the building 90 to the inside of the building 90.

By doing so, the ventilation port terminal member 1 is fixed to the ventilation hole 92, and in the fixed state, the gap between the rear end edge 35a of the installation frame 35A of the hood portion 3 and the outer wall surface 93 is filled with a gap such as a sealing material. By filling the agent, the ventilation port end member 1 is attached to the ventilation hole 92 (see FIG. 5).
