Description

この発明は、地下室を換気するための、地下室の浮き床と二重壁の換気構造に関するものである。  The present invention relates to a basement floating floor and a double wall ventilation structure for ventilating the basement.

地下室は、建築基準法において容積率の緩和が認められているため、地価の高い土地や、または狭い土地に建物を建築する際、基準となる土地の容積率に対して建物の建築面積を大きく取ることが可能となると共に、音漏れが少ないので、夜遅くでも安心して大音量での楽器の練習や、音楽、ＤＶＤ鑑賞が出来るようになるため、日本のような、特に都市部の地価が高い土地や、建ペい率が狭い土地に住宅を建設する際には、最も適している構造形態であるといえる。  Basement rooms are allowed to relax in floor area under the Building Standards Act, so when building a building on land with high land prices or on narrow land, the building area of the building is larger than the floor area ratio of the standard land. Since it can be taken and there are few sound leaks, it is possible to practice musical instruments at high volume, enjoy music, and watch DVDs even at late nights. It can be said that it is the most suitable structure when building a house on high land or land with a low building ratio.

しかしながら、地下室は機密性が高く自然換気が期待できないため、接着剤に含まれるホルムアルデヒドや化学物質等のシックハウス症候群が問題となっている。そのため、地下室の換気に対する重要性は従来から指摘されている。  However, since the basement is highly confidential and natural ventilation cannot be expected, sick house syndrome such as formaldehyde and chemicals contained in the adhesive is a problem. For this reason, the importance of basement ventilation has been pointed out.

このように、従来から地下室の換気を目的とした発明は、特許文献１に記載されたようなものがある。この特許文献１には、地下室と１階室との間で空気を循環させて、地下室の温度変化の少ない安定した空気を利用して、冬の寒期には１階室の気温よりも暖かい地下室の空気で１階室の気温を高めることができる一方、夏には１階室の気温より冷涼な地下室の空気を１階室に循環させて、１階室の温度を下げる工法が記載されている。  As described above, there is a conventional invention for ventilating a basement as described in Patent Document 1. In this patent document 1, air is circulated between the basement and the first floor room, and stable air with little temperature change in the basement is used, and in the winter cold season, it is warmer than the temperature of the first floor room. While the air in the basement can be raised by the air in the basement, in summer, a method of lowering the temperature in the first floor by circulating the air in the basement cooler than the temperature in the first floor to the first floor is described. ing.

ちなみに、地下の地温は年間を通してあまり変化せず、屋外気温と比較して、夏は低く、冬は高いことがよく知られている。例えば、東京都足立区の当社の地下室が構築されている地下３ｍの深さの地温は、当社が長年に渡り実測した結果として、夏場で約２１度、冬場で約１４度である。  By the way, it is well known that the underground temperature does not change much throughout the year and is lower in summer and higher in winter than outdoor temperature. For example, the ground temperature at a depth of 3m, where our company's basement in Adachi-ku, Tokyo is built, is about 21 degrees in summer and 14 degrees in winter, as a result of our actual measurements over many years.

さらに、前記実施例とは別に、特許文献２には、地下室の床の鋼製床パネル上に根太を介して床仕上げをすると共に、床パネル内の空気と地下室の室内空間との空気を、換気装置で循環換気することにより、鋼製床パネルの下方の地温と近似した温度の床パネル内空間の空気を、地下室の室内空間に給気することになり、夏は戸外よりも冷たい空気が循環すると共に、冬には戸外よりも暖かい空気が室内空間に給気されるため、室内空間の空気は床パネル内空間に吸引排気されて夏は冷やされ冬は温められるものが記載されている。  Further, separately from the above-described embodiment, Patent Document 2 discloses that floor finishing is performed on the steel floor panel of the basement floor via joists, and the air in the floor panel and the air in the indoor space of the basement are By circulating ventilation with a ventilator, the air in the floor panel space with a temperature approximating the ground temperature below the steel floor panel is supplied to the indoor space of the basement. As it circulates and warmer air than the outdoors is supplied to the indoor space in winter, the air in the indoor space is sucked and exhausted to the space in the floor panel and cooled in summer and warmed in winter. .

このような状況の中で、建築基準法が平成１７年に改正され、居室の換気性能が強化された事により、地下室を居室として使用する場合、地下室内の空気を２時間で全て入換える能力が必要とされるため、地下室の換気に関する関心が高まってきている。  Under such circumstances, the Building Standard Act was revised in 2005, and the ventilation performance of the living room was strengthened, so when using the basement as a living room, the ability to replace all the air in the basement in 2 hours There is a growing interest in basement ventilation.

しかしながら、このような特許文献１や特許文献２のような、従来のものは、現在の建築基準法に適合できないため、居室として使用することが困難であった。  However, since the conventional thing like such patent document 1 and patent document 2 cannot adapt to the present building standard law, it was difficult to use it as a living room.

そこで、本出願人は特許文献３に記載された、建築基準法に対応できる地下室用床下換気構造を発明し出願した。この発明によれば、建物の地上部分の外壁に設けられた空気吸込み口と、地下室のスラブ上に一定間隔をおいて浮き床が配設され、その浮き床に地下室内から浮き床の下側に空気を導入する導入口が設けられ、外壁に設けられた空気吸込み口から導かれた外気が、地下室内から浮き床の下側に導かれ、その空気を排気通路を経由して地上部分の建物外壁より外に排気させている。
特開平１５−２１３８０９ 特開平１７−１２７１１７ 特開平１８−００２３８５ Therefore, the present applicant invented and filed an underfloor ventilation structure for a basement that can be applied to the Building Standard Law described in Patent Document 3. According to the present invention, the floating floor is arranged on the outer wall of the ground portion of the building and the slab of the basement at a regular interval on the slab of the basement. The outside air introduced from the air inlet provided in the outer wall is led from the basement to the lower side of the floating floor, and the air passes through the exhaust passage to the ground part. Exhaust outside the building exterior.

以下、この発明の実施の形態１について説明する。
［発明の実施の形態１］Embodiment 1 of the present invention will be described below.
Embodiment 1 of the Invention

図１及至図７は、この発明の実施の形態１を示す。  1 to 7 show Embodiment 1 of the present invention.

図１は防火区画が有る建物の斜視図である。この建物１は、１階に居室１１と、その居室壁１０が構成され、地下室２への階段部分は防火区画４で囲まれている。  FIG. 1 is a perspective view of a building having a fire prevention section. In this building 1, a living room 11 and a living room wall 10 are formed on the first floor, and a stairway portion to the basement 2 is surrounded by a fire prevention section 4.

居室壁１０には空気取入口１２が設けられ、その居室壁１０の内部に給気通路９が設けられ、地下室２の天井４８には天井ガラリ１３が取付けられ、さらに、地下室２の床１４の四隅には、排気を取込むための床ガラリ５が設けられている。  An air intake 12 is provided in the living room wall 10, an air supply passage 9 is provided in the living room wall 10, a ceiling gallery 13 is attached to the ceiling 48 of the basement 2, and a floor 14 of the basement 2 is further provided. In the four corners, floor gallery 5 for taking in the exhaust is provided.

このように構成された居室１１内の空気は矢印Ａで示すように、空気取入口１２から取込まれ、給気通路９を経由して天井ガラリ１３より矢印Ｂで示すように地下室２の室内に送り込まれる。  The air in the living room 11 configured as described above is taken from the air intake 12 as indicated by an arrow A, and the room of the basement 2 is indicated by an arrow B from the ceiling gallery 13 via the air supply passage 9. Is sent to.

さらに、このように送り込まれた空気は、地下室２の床１４の四隅に設けられた、排気を取込むための床ガラリ５より矢印Ｃで示すように床１４内の床下排気通路３１に導かれ、二重壁内に設けられた排気通路８を経由して矢印Ｆで示すように建物１外に排出される。  Further, the air sent in this way is led to an under-floor exhaust passage 31 in the floor 14 as indicated by an arrow C from a floor gallery 5 provided at the four corners of the floor 14 of the basement 2 for taking in the exhaust. Then, it is discharged out of the building 1 as shown by the arrow F through the exhaust passage 8 provided in the double wall.

図２及至図４は、浮き床２６と二重壁３０の構造と、地下室２内の排気方法を示す。  FIGS. 2 to 4 show the structure of the floating floor 26 and the double wall 30 and the exhaust method in the basement 2.

図２ａに示すように、地下室２の四隅に床ガラリ５が構成され、排気口３３と対向する位置に浮き床から二重壁への排気口２４が設けられている。さらに、図２ｃで示すように、浮き床２６は支持脚２８で支えられて床スラブ２７との間に床下排気通路３１を設けるように構成され、浮き床２６は壁スラブ２３と当接するように置かれ、その上部にフローリング２７が施工される。なお、排気口３３と浮き床から二重壁への排気口２４の位置関係は、二重壁内を流れる排気の量を二重壁内の何れの位置でも一定にするために、地下室の相対向する位置に配置するのが望ましい。  As shown in FIG. 2 a, floor louvers 5 are formed at the four corners of the basement 2, and exhaust ports 24 from the floating floor to the double wall are provided at positions facing the exhaust ports 33. Further, as shown in FIG. 2 c, the floating floor 26 is supported by the support legs 28 and is configured to provide an underfloor exhaust passage 31 between the floating floor 26 and the floating floor 26 so as to contact the wall slab 23. The flooring 27 is installed on the top of the floor. Note that the positional relationship between the exhaust port 33 and the exhaust port 24 from the floating floor to the double wall is such that the amount of exhaust flowing through the double wall is constant at any position within the double wall. It is desirable to arrange in the position to face.

また、図３に示すように、二重壁３０は、壁スラブ２３にスクリューパッキン２９を固定し、そのスクリューパッキン２９に石膏ボード２５を固定すると共に、該石膏ボード２５の下部は浮き床２６に当接するように置かれ浮き床２６下の空気が二重壁３０に直接流れ込まないように二重壁内排気通路３６を構成する。  As shown in FIG. 3, the double wall 30 has a screw packing 29 fixed to the wall slab 23, a gypsum board 25 fixed to the screw packing 29, and the lower part of the gypsum board 25 is connected to a floating floor 26. The double-wall exhaust passage 36 is configured so as to prevent the air below the floating floor 26 from flowing directly into the double wall 30.

図４は地下室内の空気を室外へ排気させるための構造に関する断面図である。  FIG. 4 is a cross-sectional view relating to a structure for exhausting air in the basement to the outside.

床スラブ６の上に支持脚２８を置くと共に、その上部に浮き床２６を固定し、さらに、その上部にはフローリング２７が構成される。石膏ボード２５は図３に示すようにスクリューパッキン２９により壁スラブ２３に固定される。このようにして構成された二重壁内排気通路３６の内部に排気ダクト８を取付けると共に、その排気ダクト８に排気ファン３２を取付け、建物の外側に排気口３３を取付ける。なお、排気通路カバー３４は排気ダクト８を保護するためのものである。  A support leg 28 is placed on the floor slab 6, a floating floor 26 is fixed on the upper part, and a flooring 27 is formed on the upper part. The gypsum board 25 is fixed to the wall slab 23 by screw packing 29 as shown in FIG. The exhaust duct 8 is attached to the inside of the double-wall exhaust passage 36 thus configured, the exhaust fan 32 is attached to the exhaust duct 8, and the exhaust port 33 is attached to the outside of the building. The exhaust passage cover 34 is for protecting the exhaust duct 8.

このように構成された、排気ファン３２を駆動することにより、地下室内の空気は矢印Ｃで示すように、床ガラリ５から吸い込まれ、矢印Ｄで示すように、床下排気通路３１を経由して浮き床から二重壁への排気口２４を通過して二重壁内排気通路３６に導かれ、排気ダクト吸込み口３７より吸い込まれ、排気ダクト８を経由して排気口３３より矢印Ｆで示すように建物外に排出される。  By driving the exhaust fan 32 configured as described above, the air in the basement is sucked from the floor gallery 5 as indicated by the arrow C, and passes through the underfloor exhaust passage 31 as indicated by the arrow D. It passes through the exhaust port 24 from the floating floor to the double wall, is led to the double wall exhaust passage 36, is sucked in from the exhaust duct suction port 37, and is indicated by the arrow F from the exhaust port 33 through the exhaust duct 8. So that it is discharged outside the building.

なお、湿度の高い空気は二重壁内の下部に滞留するため、排気ダクト吸込み口３７は、二重壁内排気通路３６のできるだけ下部に設けることが好ましい。  Since air with high humidity stays in the lower part of the double wall, the exhaust duct suction port 37 is preferably provided as low as possible in the double-wall exhaust passage 36.

また、浮き床から二重壁への排気口２４は、石膏ボード２５と壁スラブ２３との間の間隔が狭く、風切音が発生するため、横長にして開口面積を広く取ることが望ましい。実際に構成する場合においては、地下室内の広さにもよるが、浮き床から二重壁への排気口２４は縦３〜４センチメートル、横４０〜５０センチメートルとすることが望ましい。  Moreover, since the space | interval between the gypsum board 25 and the wall slab 23 has a narrow space | interval and the wind noise generate | occur | produces, it is desirable for the exhaust port 24 from a floating floor to a double wall to take a wide opening area widely. In an actual configuration, the exhaust port 24 from the floating floor to the double wall is preferably 3 to 4 cm in length and 40 to 50 cm in width, depending on the size of the basement.

図５は、地下室内の給気に関する地下室の断面図である。  FIG. 5 is a cross-sectional view of the basement for air supply in the basement.

１階の居室壁１０と石膏ボート５３で囲まれた空間の、１階床４７と１階天井４６の、概ね中間部分より上部に空気取入口１２を設けると共に、１階居室壁１０と石膏ボート５３で囲まれた空間に給気通路９を構成し、その給気通路９を地下室天井４８部分まで延長し地下室天井４８に天井ガラリ１３を取付ける。  In the space surrounded by the first-floor room wall 10 and the gypsum boat 53, the first-floor floor 47 and the first-floor ceiling 46 are provided with an air intake 12 approximately above the middle portion, and the first-floor room wall 10 and the gypsum boat An air supply passage 9 is formed in the space surrounded by 53, the air supply passage 9 is extended to the basement ceiling 48, and the ceiling gallery 13 is attached to the basement ceiling 48.

このようにして構成された給気通路９に対して、居間１１の室内空気が矢印Ａで示すように空気取入口１２より取込まれ給気通路９を経由して矢印Ｂで示すように地下室２に供給される。  The indoor air in the living room 11 is taken in from the air intake 12 as shown by the arrow A with respect to the air supply passage 9 configured in this way, and the basement as shown by the arrow B through the air supply passage 9. 2 is supplied.

なお、湿度の高い空気や、汚れた空気は居室内の低い位置に停滞するため空気取入口１２の位置は、居室の概ね中間部分より上部に設けることが望ましい。  In addition, since air with high humidity or dirty air stagnates at a low position in the living room, it is desirable that the position of the air intake 12 is provided above the middle part of the living room.

図７は、地下室内における湿度センサー付排気装置の断面図である。  FIG. 7 is a cross-sectional view of the exhaust device with a humidity sensor in the basement.

図１で示した床ガラリ５と同様に地下室２の四隅に排気口７０を設けると共に、湿気センサー６９と給気ファン６８並びに開閉式ダンパー６７で構成された排気装置６６を取付ける。  As with the floor gallery 5 shown in FIG. 1, exhaust ports 70 are provided at the four corners of the basement 2, and an exhaust device 66 composed of a moisture sensor 69, an air supply fan 68 and an open / close damper 67 is attached.

このように構成された湿度センサー付排気装置は、通常は、開閉式ダンパー６７が閉口した状態で、なおかつ給気ファン６８が停止した状態に置かれるが、湿気センサー６９が一定以上の湿度を感知することにより、開閉式ダンパー６７を開口し、給気ファン６８が運転を開始して地下室内の空気は矢印Ｋで示すように給気ファン６８により給気され矢印Ｌに示すように地下排気通路４０に導かれる。  The exhaust device with a humidity sensor configured as described above is normally placed in a state in which the open / close damper 67 is closed and the air supply fan 68 is stopped, but the humidity sensor 69 senses a certain level of humidity. As a result, the open / close damper 67 is opened, the air supply fan 68 starts to operate, and the air in the basement is supplied by the air supply fan 68 as indicated by the arrow K, and the underground exhaust passage as indicated by the arrow L. 40.
