Description

本発明は、階段室を備える共同住宅に関する。   The present invention relates to an apartment house provided with a staircase.

共同住宅において、世帯間の仕切となる床と壁は耐火・遮音構法による界床と界壁で構成されている(例えば特許文献1参照)。
2階建て共同住宅では階段室が備えられており、その階段室は周りを界壁により囲まれていて上階居住者用の専用区域となっていた。
特開2000−110377号公報
In an apartment house, the floor and wall that serve as a partition between households are composed of a floor and a wall by a fireproof / sound insulation construction method (see, for example, Patent Document 1).
The two-story apartment house has a staircase, which is surrounded by a border wall and is a dedicated area for upper-floor residents.
JP 2000-110377 A

しかし、周りを界壁により囲まれた階段室の階段下スペースは何も利用されないデッドスペースとなっていた。   However, the space below the stairs in the staircase surrounded by the boundary wall was a dead space where nothing was used.

本発明の課題は、階段室を備える共同住宅において、階段下スペースを下階居住者用の占有区域として利用可能とすることである。   An object of the present invention is to make it possible to use a space under the stairs as an occupied area for a resident of a lower floor in an apartment house including a staircase.

以上の課題を解決するため、請求項1に記載の発明は、例えば図1及び図2に示すように、階段室1を備える共同住宅であって、階段室1において、階段5の段板54の下側に、当該階段5の勾配に沿った傾斜界壁8を形成し、
前記階段5の勾配に沿って前記段板54の下側に張られた耐火ボード(石膏ボード)56の下側に沿って前記傾斜界壁8が前記耐火ボード56と間隔を持って位置し、
前記階段室1の周囲に形成した界壁6・61に前記傾斜界壁8の上端および前記耐火ボード56の上端が接続され、
前記傾斜界壁8は上下の耐火ボード(石膏ボード)81の間に断熱材82を設けた構造であることを特徴とする。
In order to solve the above-described problems, the invention described in claim 1 is an apartment house including a staircase 1 as shown in FIGS. 1 and 2, for example. An inclined boundary wall 8 along the slope of the staircase 5 is formed on the lower side,
The inclined boundary wall 8 is located at a distance from the fireproof board 56 along the lower side of the fireproof board (gypsum board) 56 stretched below the stepboard 54 along the gradient of the staircase 5.
Top and the upper end of the refractory board 56 of the inclined boundary wall 8 is connected to Sakaikabe 6, 61 formed around the stairwell 1,
The inclined wall 8 has a structure in which a heat insulating material 82 is provided between upper and lower refractory boards (gypsum board) 81 .

このように、共同住宅の階段室において、階段の段板の下側に、当該階段の勾配に沿った傾斜界壁を形成することで、階段下スペースを傾斜界壁により仕切って下階居住者用の占有区域としての利用が可能になる。   As described above, in the staircase of the apartment house, by forming an inclined wall along the slope of the staircase below the staircase plate, the lower floor residents are partitioned by the inclined wall. Can be used as an occupation area.

このように、階段の勾配に沿って段板の下側に張られた耐火ボードの下側に沿って傾斜界壁を位置させることで、耐火・遮音性が高められる。   In this way, by positioning the inclined boundary wall along the lower side of the fireproof board stretched below the step board along the gradient of the stairs, the fire resistance and sound insulation are improved.

このように、階段室周囲の界壁に傾斜界壁を接続することで、階段下スペースを耐火・遮音上区画できる。   In this way, by connecting the inclined wall to the wall around the staircase, the space under the staircase can be partitioned for fireproofing and sound insulation.

請求項に記載の発明は、請求項1に記載の共同住宅であって、例えば図1及び図2に示すように、前記階段室1に、前記傾斜界壁8の下方に形成された下階居住者用スペースSへの出入りを可能とする開口部9を形成したことを特徴とする。 The invention according to claim 2 is the apartment house according to claim 1 , for example, as shown in FIGS. 1 and 2, the lower part formed in the staircase 1 below the inclined wall 8. An opening 9 that allows entry into and exit from the space S for floor residents is formed.

このように、階段室に、傾斜界壁の下方に形成された下階居住者用スペースへの出入りを可能とする開口部を形成することで、階段下スペースに下階居住者が出入りできる。   In this way, by forming an opening in the staircase that allows access to the lower floor occupant space formed below the inclined boundary wall, the lower floor resident can enter and exit the lower stairs space.

請求項1に記載の発明によれば、共同住宅の階段室の階段下スペースを傾斜界壁により仕切って下階居住者用の占有区域として利用できる。   According to the first aspect of the present invention, the space below the staircase of the staircase of the apartment house can be partitioned by the inclined boundary wall and used as an occupation area for the lower floor residents.

また、階段の段板下側に張られた耐火ボードの下側に沿って傾斜界壁を前記耐火ボードと間隔を持って位置させることによって、耐火・遮音性が高められるといった利点が得られる。 In addition , by placing the inclined wall at a distance from the refractory board along the lower side of the refractory board stretched on the lower side of the step board of the staircase, there is an advantage that the fire resistance and sound insulation can be improved.

また、階段室周囲の界壁に傾斜界壁および前記耐火ボードを接続することによって、階段下スペースを耐火・遮音上区画できるといった利点が得られる。 Further , by connecting the sloped wall and the fireproof board to the field wall around the staircase, there is an advantage that the space under the staircase can be divided in terms of fireproofing and sound insulation.

請求項に記載の発明によれば、請求項1の発明により得られる効果に加え、階段室に、傾斜界壁下方の下階居住者用スペースへの出入りを可能とする開口部を形成することによって、階段下スペースに下階居住者が出入りできるといった利点が得られる。 According to the second aspect of the present invention, in addition to the effect obtained by the first aspect of the present invention, the staircase is formed with an opening that allows access to the lower floor occupant space below the inclined wall. Thus, there is an advantage that a lower floor resident can enter and exit the space under the stairs.
