Description

【０００１】
【発明の属する技術分野】
本発明は、建物付設物の床構造に係り、例えば、バルコニ、ベランダ、テラス、集合住宅用外階段や外廊下等の建物付設物における床に利用できるものである。
【０００２】
【背景技術】
建物の付設物となっているバルコニのデッキ材方式の床は、支持部材である複数の根太を平行に並設し、これらの根太の上に床部材であるデッキ材を載せ、デッキ材を根太に、デッキ材を貫通して根太まで達する固定ねじ等による止着具で固定することにより形成される。
【０００３】
この従来の床構造では、止着具はデッキ材を上下に貫通しているため、デッキ材には止着具が挿通する貫通孔が上下に形成される。このため、デッキ材上に降る又はデッキ材上を流れる雨水がこの貫通孔を通って根太から落下するのを防止するために、貫通孔の箇所を防水処理することが必要になり、貫通孔を防水シールで塞ぐことが行われている。
【０００４】
【発明が解決しようとする課題】
これによると、防水シールの施工作業が必要となり、それだけバルコニ施工作業にかかる手間が多くなり、作業効率の向上を阻害する要因ともなる。
【０００５】
本発明の目的は、デッキ材等の床部材に形成される止着具挿通用貫通孔についての防水処理作業を不要にできるように建物付設物の床構造を提供するところにある。
【０００６】
【課題を解決するための手段】
本発明に係る建物付設物の床構造は、建物付設物の床部材が支持部材の上に載せられるとともに、前記床部材を貫通して前記支持部材に達する止着具で前記床部材が前記支持部材に固定される建物付設物の床構造において、前記支持部材の上面における前記止着具による床部材固定箇所に排水用凹部が形成され、この排水用凹部の端部が樋部材に臨んで開口していることを特徴とするものである。
【０００７】
この建物付設物の床構造によると、支持部材の上面における止着具による床部材固定箇所には排水用凹部が形成されるため、止着具が挿通する貫通孔が床部材に形成されていても、この貫通孔を通って支持部材に達した雨水はこの排水用凹部に落下することになり、そして、この排水用凹部の端部は樋部材に臨んで開口しているため、雨水は排水用凹部から樋部材へと流下することになり、建物付設物の外部へ排出される。
【０００８】
このため、床部材を支持部材に固定するための止着具が挿通する床部材の貫通孔を防水シールで塞ぐなどの防水処理作業が不要になり、それだけ建物付設物の施工作業にかかる手間を削減できることになる。
【０００９】
以上において、前記支持部材は、根太のように細長状部材であって複数個が並設等されるものでもよく、また、比較的大きな面積を有するパネル状又は厚板状のものであって１個又は複数個で床部材を支持するものでもよい。
【００１０】
また、前記排水用凹部は、支持部材が根太のように細長状部材である場合には、この細長状部材の長手方向に延びる溝状のものでもよく、支持部材が比較的大きな面積を有するパネル状又は厚板状のものである場合には、溝状のものや支持部材の大きな面積に亘って窪んだ窪み状のものでもよい。
【００１１】
また、支持部材は中実のものでもよく、また、排水用凹部の下部における支持部材の内部に空洞部がある中空のものでもよい。
【００１２】
支持部材が後者の場合であって、前記止着具の先端がこの空洞部まで達するときは、前記空洞部の端部を前記樋部材に臨んで開口させるようにする。
【００１３】
これによると、止着具の先端が空洞部に達し、このため、支持部材に、排水用凹部からこの空洞部まで貫通して止着具が挿通する貫通孔があり、排水用凹部内の雨水がこの貫通孔を通って空洞部に落下することがあっても、この雨水は空洞部に案内されて樋部材へと流下し、建物付設物の外部へ排出されることになる。
【００１４】
また、排水用凹部から外れた箇所における支持部材の上面と床部材の下面とは直接接触させてもよく、あるいは、支持部材の上面と床部材の下面との間に防水部材を介設してもよい。
【００１５】
後者によると、床部材の止着具挿通用貫通孔から排水用凹部に落下した雨水が排水用凹部を越えて支持部材の外部へ落ちるのを防水部材によってより確実に阻止することができ、雨水の雨仕舞いを一層有効に行える。
【００１６】
また、前記排水用凹部や前記空洞部の端部が臨んでいてこれらの排水用凹部や空洞部を流下した雨水が落下する前記樋部材は、建物付設物に特別に設けたものでもよく、あるいは、樋部材を建物付設物に必要な部材、具体的には、支持部材が載せられて受けられる受け部材としてもよい。
【００１７】
樋部材を後者とすると、樋部材は建物付設物に必要な部材によって兼用化されることになり、それだけ必要とされる部材点数を削減でき、床構造の簡単化を達成できる。
【００１８】
また、前記樋部材は、建物付設物の構造材、すなわち、建物付設物の骨組み材でもよい。
【００１９】
これによると、樋部材は建物付設物の構造材で兼用化されることになり、これによっても部材点数を削減でき、床構造の簡単化を達成できる。
【００２０】
また、樋部材を支持部材が載せられて受けられる受け部材であって建物付設物の構造材とすると、一層の部材点数の削減、構造の簡単化を図ることができるとともに、構造材は充分の強度を有するため、支持部材を充分な強度で受けることができるようになる。
【００２１】
このように樋部材を建物付設物の構造材とする場合には、この構造材は桁材でもよく、妻材でもよい。
【００２２】
以上において、床部材を貫通してこの床部材を支持部材に固定するための前記止着具は、ボルトやビス等のねじでもよく、リベットでもよく、ピンでもよく、ステープルでもよく、任意な止着具でよい。
【００２３】
また、本発明に係る床構造が適用される建物付設物は、バルコニでもよく、ベランダでもよく、テラスでもよく、集合住宅の外階段でもよく、集合住宅の外廊下でもよく、任意な建物付設物に本発明に係る床構造を適用できる。
【００２４】
また、本発明に係る建物付設物がバルコニである場合には、前記床部材はデッキ材でもよく、防水パンでもよく、任意な床部材によって形成される床に本発明を適用できる。
【００２５】
【発明の実施の形態】
以下に本発明の一実施形態を図面に基づいて説明する。本実施形態に係る床構造が適用された建物付設物はバルコニであり、図１は、このバルコニ１の側面図である。
【００２６】
建物２の外壁２Ａからはアーム部材３が突設され、このアーム部材３にボルト・ナット４でバルコニの構造材である妻材５が結合されている。このようにアーム部材３を介して外壁２Ａに結合された妻材５は、建物１の桁方向（図面上、図１と直交する方向）に複数本あり、互い隣接する妻材５同士の間にバルコニ１の構造材である桁材６が架設されている。これらの妻材５及び桁材６にバルコニ１の手摺り７が立設され、これによってバルコニ１の輪郭構造が形成されている。
【００２７】
バルコニ１の床は、根太１０の上に床部材であるデッキ材１１を載せることにより形成されており、図２は、この床の部分を示す縦断面図である。複数のデッキ材１１をその上に載せて支持する支持部材となっている根太１０は、建物の桁方向、言い換えると桁材６の長手方向に複数並設されている。建物２の外壁２Ａにはアングル材による受け部材８が取り付けられ、この受け部材８の下端のフランジ部８Ａにそれぞれの根太１０の建物２側の端部が載せられて受けられている。
【００２８】
また、桁材６は内部が中空室Ｓ１となった中空材であるとともに、建物２と対向する側の側面には開口部６Ａが形成され、この開口部６Ａの下端は、建物２側へ屈曲突出する突出部６Ｂとなっている。それぞれの根太１０の桁材６側の端部はこの突出部６Ｂに載せられ、したがって、バルコニ１の構造材である桁材６は、根太１０の桁材６側の端部が載せられて受けられる受け部材として利用されている。
【００２９】
図４は、図２のＳ４−Ｓ４線断面図である。根太１０はアルミ合金製の引き抜き成形品又は押し出し成形品であり、長手方向に同一断面が連続したものとなっている。すなわち、根太１０は、下端のフランジ部１０Ａと、このフランジ部１０Ａから根太１０の幅方向に一定間隔離れて立ち上がった２個の立上部１０Ｂと、これらの立上部１０Ｂの上端の間にフランジ部１０Ａと平行に架設された蓋部１０Ｃと、それぞれの立上部１０Ｂを延長した箇所に蓋部１０Ｃを越えて上方へ少し延びて形成された延出部１０Ｄとからなる。
【００３０】
このため、根太１０には、蓋部１０Ｃより上の上面に相当する箇所において、延出部１０Ｄで両側の堤部が形成された排水用凹部としての排水用溝１２が設けられており、また、蓋部１０Ｃの下、言い換えると根太１０の内部には、フランジ部１０Ａと立上部１０Ｂと蓋部１０Ｃとで囲まれた空洞部Ｓ２が設けられている。
【００３１】
図２に示すように、根太１０は、フランジ部１０Ａが前記受け部材８のフランジ部８Ａと桁材６の突出部６Ｂとに載せられて建物２と桁材６との間に架設されるとともに、フランジ部１０Ａに螺入されるボルト１３でこれらの受け部材８のフランジ部８Ａと桁材６の突出部６Ｂとに結合されている。
【００３２】
また、図４に示すように、根太１０の上には前述したデッキ材１１が載せられ、このデッキ材１１は、根太１０の排水用溝１２の上部を塞いだ状態で止着具である固定ねじ１４により根太１０の蓋部１０Ｃに固定されている。
【００３３】
図３は、デッキ材１１を前記バルコニ１の妻材５側から見た斜視図である。合成樹脂製であるこのデッキ材１１は、下面部１１Ａと、上面部１１Ｂと、これらの下面部１１Ａと上面部１１Ｂとの間を繋ぐ複数の仕切り部１１Ｃとからなる中空品であり、幅方向の途中部には上面部１１Ｂが途切れた凹部１１Ｄが設けられているとともに、幅方向の一方の端部には上面部１１Ｂが設けられていない溝部１１Ｅが形成され、幅方向の他方の端部には上面部１１Ｂがそのまま延長した延長部１１Ｆが設けられている。
【００３４】
このような形状が根太１０の長手方向と直交する方向に連続している複数のデッキ材１１が、溝部１１Ｅの上に延長部１１Ｆが被せられた状態で幅方向（根太１０の長手方向）に並設され、図２に示すとおり、それぞれのデッキ材１１はそれぞれの根太１０の上に載せられるとともに、凹部１１Ｄにおいて下面部１１Ａを貫通した固定ねじ１４により根太１０に固定され、この固定ねじ１４の先端は根太１０の蓋部１０Ｃも貫通し、根太１０の内部の空洞部Ｓ２まで達している。
【００３５】
このように固定ねじ１４でそれぞれのデッキ材１１をそれぞれの根太１０に固定する作業を行った後、それぞれのデッキ材１１の凹部１１Ｄには、図３で示した下向きのコ字形状となっているカバー１５が嵌入され、これにより凹部１１は塞がれる。
【００３６】
図２で示された本実施形態では、根太１０は桁材６側への下り勾配をもって配設されており、したがって、図２で示したそれぞれのデッキ材１１も桁側６へ下り勾配で傾斜している。
【００３７】
また、根太１０の桁材６側の端部は桁材６の前記開口部６Ａから少し桁材６の内部に挿入されており、このため、根太１０の上面に形成されている前記排水用溝１２の端部は桁材６の内部の中空室Ｓ１に臨んで開口し、根太１０の内部に形成されている空洞部Ｓ２の端部も中空室Ｓ１に臨んで開口している。また、それぞれのデッキ材１１のうち、桁材６に最も近いデッキ材１１の桁材６側の端部も桁材６の開口部６Ａから少し桁材６の内部に挿入されている。
【００３８】
雨天時にデッキ材１１の上に降った雨水は、桁材６側への下り勾配となっているカバー１５の上面を含むデッキ材１１上を桁材６側へ流下し、そして桁材６の中空室Ｓ１に落下する。また、デッキ材１１上を流下している途中において、カバー１５との隙間から凹部１１Ｄへ落ちた雨水は、この凹部１１Ｄのそれぞれの妻材５側の端部が、桁材６と同じく内部が中空室となっている妻材５のこの中空室に臨んで開口しているため、凹部１１Ｄ内を流れてこの妻材５の中空室に落下する。
【００３９】
妻材５と桁材６との接合部の下面には、図１で示す接続管１６の一端部が接続されており、接続管１６の他端部には縦樋１７が接続されているため、妻材５の中空室へ落下した雨水は妻材５から接続管１６を経てこの縦樋１７へと導かれ、これによりバルコニ１の外部へ排出される。
【００４０】
また、それぞれデッキ材１１は、凹部１１Ｄにおいてこれらのデッキ材１１の下面部１１Ａを上下に貫通した固定ねじ１４で根太１０に固定され、図２及び図４に示すように、この下面部１１Ａには固定ねじ１４が挿通している貫通孔１８があるため、デッキ材１１上を桁材６側へ流下している途中でカバー１５との隙間から凹部１１Ｄへ落下した雨水のうち、一部の雨水は、貫通孔１８を通って根太１０の上面に達するが、この上面には排水用溝１２が設けられているため、根太１０の上面に達する雨水は排水用溝１２へ落下することになる。この後、雨水は排水用溝１２に沿って桁材６の中空室Ｓ１へ流下し、この後は、妻材５の中空室へ落下した雨水と同じく、接続管１６を経て縦樋１７からバルコニ１の外部へ排出される。
【００４１】
このため、本実施形態では、バルコニ１の全体強度を確保するための構造材となっている桁材６は、その内部に雨水が落下してこの雨水をバルコニ１の外部へ排出するための樋部材ともなっている。
【００４２】
また、排水用溝１２の底部を形成している根太１０の蓋部１０Ｃにも、空洞部Ｓ２に達している固定ねじ１４が挿通した貫通孔１９があり、排水用溝１２を流下する雨水の一部はこの貫通孔１９から根太１０の内部に達するが、この内部には、端部が桁材６の中空室Ｓ１に臨んで開口している空洞部Ｓ２が形成されているため、根太１０の内部に達する雨水はこの空洞部Ｓ２へ落下することになり、この後、雨水は空洞部Ｓ２に沿って桁材６の中空室Ｓ１へ流下し、接続管１６を経て縦樋１７からバルコニ１の外部へ排出される。
【００４３】
以上説明したように本実施形態によると、デッキ材１１が、このデッキ材１１の下面部１１Ａの貫通孔１８に挿通された固定ねじ１４で根太１０に固定され、雨水が貫通孔１８から根太１０の上面に達しても、この上面には排水用溝１２が形成されていて、排水用溝１２の端部は桁材６の中空室Ｓ１に臨んで開口しているため、雨水を排水用溝１２により案内流下させて中空室Ｓ１へ導くことができる。
【００４４】
このため、固定ねじ１４が挿通される貫通孔１８を防水シール等で防水処理する作業を行う必要がなくなり、それだけバルコニ１の施工作業についての手間や作業工数を削減することができる。
【００４５】
また、根太１０の内部に空洞部Ｓ２があり、この空洞部Ｓ２に達する固定ねじ１４が挿通された貫通孔１９が排水用溝１２の底部となっている根太１０の蓋部１０Ｃに存在し、排水用溝１２を流下する雨水の一部がこの貫通孔１９から根太１０の内部に達しても、空洞部Ｓ２の端部も桁材６の中空室Ｓ１に臨んで開口しているため、雨水を空洞部Ｓ２により案内流下させて中空室Ｓ１へ導くことができる。
【００４６】
また、本実施形態によると、根太１０の排水用溝１２や空洞部Ｓ２を流下した雨水は桁材６の中空室Ｓ１へ落下した後、この中空室Ｓ１に導かれてバルコニ１の外部へと排出されることになるため、桁材６を雨水をバルコニ１の外部へ排出するための樋部材としても利用することができる。
【００４７】
さらに、桁材６には、根太１０の桁材６側の端部が載せられて受けられる突出部６Ｂが設けられ、このため、桁材６は、図２で示す建物２に取り付けられた受け部材８と共に根太１０が載せられて受けられる受け部材ともなっており、バルコニ１の構造上、根太１０の端部を載せて受けるために必要な受け部材を桁材６が兼ねている。
【００４８】
このため、バルコニ１の床を組み立てるために必要な部材の点数を削減でき、また、この床の構造を簡単化することができる。
【００４９】
図５は、根太１０の排水用溝１２を多量の雨水が流下しても、この排水用溝１２から雨水が溢れるのを防止できるようにした実施形態を示す。この実施形態では、排水用溝１２の両側の堤部となっている根太１０の前記延出部１０Ｄの上部に防水部材２０が配置され、これにより、排水用溝１２から外れた箇所における根太１０の上面とデッキ材１１の下面との間に防水部材２０が介設されている。したがって、防水部材２０によって排水用溝１２から外れた箇所における根太１０の上面とデッキ材１１の下面とが水密に密接することになり、排水用溝１２を多量の雨水が流下しても、この排水用溝１２からの雨水が溢れることはない。
【００５０】
図６の実施形態では、根太１０及びそれぞれのデッキ材１１は建物２と桁材６との間に水勾配なしで水平に配置されている。このため、根太１０の建物２側の端部を載せて受けるための受け部材２８は、樋部材を兼ねたものとなっている。
【００５１】
すなわち、根太１０の建物２側の端部が載せられて受けられる受け部材２８の下端のフランジ部２８Ａには、受け部材２８の長手方向に延びる溝２９が形成され、この溝２９の両端部は蓋２９Ａで塞がれているとともに、受け部材２８の適所には溝２９に接続された縦樋３０が結合されている。このため、根太１０の排水用溝１２や空洞部Ｓ２を流れて根太１０の建物２側の端部に達した雨水は、溝２９へ落下し、この後、溝２９に案内されて縦樋３０からバルコニ１の外部へと排出される。
【００５２】
また、根太１０の排水用溝１２や空洞部Ｓ２を流れて根太１０の桁材６側の端部に達した雨水は、前記実施形態と同じく、接続管１６を経て縦樋１７からバルコニ１の外部へ排出される。
【００５３】
図６の実施形態のように樋部材を兼ねる建物２側の受け部材２８は、根太１０及びデッキ材１１が建物２側への下り勾配をもって配置される場合にも適用できる。
【００５４】
また、以上のそれぞれの実施形態におけるデッキ材１１は根太１０の長手方向と直交する方向に延び、根太１０の長手方向を幅方向とするものであったが、前述したそれぞれの実施形態は、デッキ材が根太１０の長手方向に延び、根太１０の長手方向と直交する方向をデッキ材の幅方向とする場合にも適用できる。
【００５５】
また、以上説明した実施形態において、根太１０の排水用溝１２や空洞部Ｓ２を流れる水は雨水であったが、この水がバルコニ１に降る雪が解けた融雪水である場合にも、以上と同様にこの水を排水処理できる。
【００５６】
【発明の効果】
本発明によると、デッキ材等の床部材に形成される止着具挿通用貫通孔についての防水処理作業を不要にできるという効果を得られる。

BACKGROUND OF THE INVENTION
The present invention relates to a floor structure of a building accessory, and can be used for a floor in a building accessory such as a balcony, a veranda, a terrace, an outer staircase for an apartment house, an outer corridor, or the like.
[0002]
[Background]
The floor of the deck material system of Balconi, which is an accessory of the building, has a plurality of joists as support members arranged in parallel, and deck materials as floor members are placed on these joists, and the deck material is joisted. Further, it is formed by fixing with a fastening tool such as a fixing screw that penetrates the deck material and reaches the joist.
[0003]
In this conventional floor structure, since the fastening tool penetrates the deck material vertically, a through hole through which the fastening tool is inserted is formed vertically in the deck material. For this reason, in order to prevent rain water falling on the deck material or flowing on the deck material from falling through the through hole, it is necessary to waterproof the portion of the through hole. Blocking with a waterproof seal is performed.
[0004]
[Problems to be solved by the invention]
According to this, the construction work of the waterproof seal is required, and the labor for the balconi construction work is increased accordingly, which becomes a factor that hinders the improvement of work efficiency.
[0005]
An object of the present invention is to provide a floor structure of a building accessory so as to eliminate the need for waterproofing work for a through hole for inserting a fastener formed in a floor member such as a deck material.
[0006]
[Means for Solving the Problems]
In the floor structure of a building accessory according to the present invention, the floor member of the building accessory is placed on the support member, and the floor member is supported by the fastening member that penetrates the floor member and reaches the support member. In the floor structure of a building attachment fixed to a member, a drainage recess is formed at a floor member fixing position by the fastening device on the upper surface of the support member, and an end of the drainage recess faces the trough member and opens. It is characterized by that.
[0007]
According to the floor structure of the building accessory, a drainage recess is formed at the floor member fixing portion on the upper surface of the support member, so that a through hole through which the fastener is inserted is formed in the floor member. However, the rainwater that has reached the support member through this through-hole will fall into this drainage recess, and the end of this drainage recess opens to the saddle member, so the rainwater is drained. It will flow down from the concave portion to the eaves member and is discharged to the outside of the building attachment.
[0008]
This eliminates the need for waterproofing work such as closing the through hole of the floor member through which the fastener for fixing the floor member to the support member is inserted with a waterproof seal. It can be reduced.
[0009]
In the above, the support member may be an elongated member such as a joist, and a plurality of the support members may be arranged side by side, or may be a panel or thick plate having a relatively large area. One or a plurality of floor members may be supported.
[0010]
Further, when the supporting member is an elongated member such as a joist, the drain recess may be a groove extending in the longitudinal direction of the elongated member, and the supporting member has a relatively large area. When it is in the shape of a plate or thick plate, it may be in the shape of a groove or a depression that is recessed over a large area of the support member.
[0011]
The support member may be solid, or may be a hollow member having a hollow portion inside the support member at the lower part of the concave portion for drainage.
[0012]
In the latter case, when the tip of the fastener reaches the cavity, the end of the cavity is opened facing the flange member.
[0013]
According to this, the tip of the fastening device reaches the cavity, and therefore, the support member has a through-hole through which the fastening device passes from the drain recess to the cavity, and rainwater in the drain recess Even if the water drops through the through hole and falls into the cavity, the rainwater is guided to the cavity and flows down to the eaves member and is discharged to the outside of the building attachment.
[0014]
Further, the upper surface of the support member and the lower surface of the floor member may be in direct contact with each other at a place removed from the drain recess, or a waterproof member is interposed between the upper surface of the support member and the lower surface of the floor member. Also good.
[0015]
According to the latter, the waterproof member can more reliably prevent rainwater that has fallen from the through hole for inserting the fastener of the floor member into the drainage recess to fall outside the drainage through the drainage recess. It is possible to more effectively perform the rain.
[0016]
Further, the drainage recess and the end of the cavity faced, and the dredging member from which the rainwater flowing down the drainage recess and cavity falls may be specially provided in a building accessory, or In addition, the eaves member may be a member necessary for a building accessory, specifically, a receiving member on which a support member is placed and received.
[0017]
When the saddle member is the latter, the saddle member is shared by the members necessary for the building attachment, so that the number of required members can be reduced and the floor structure can be simplified.
[0018]
Moreover, the said eaves member may be a structural material of a building attachment, that is, a framework material of a building attachment.
[0019]
According to this, the eaves member is shared with the structural material of the building attachment, and this can also reduce the number of members and achieve the simplification of the floor structure.
[0020]
Moreover, when the eaves member is a receiving member on which a support member is placed and is used as a structural material for a building accessory, the number of members can be further reduced, the structure can be simplified, and the structural material is sufficient. Since it has strength, the support member can be received with sufficient strength.
[0021]
In this way, when the eaves member is used as a structural material for a building accessory, the structural material may be a girder or a wife.
[0022]
In the above, the fastener for penetrating the floor member and fixing the floor member to the support member may be a screw such as a bolt or a screw, a rivet, a pin, a staple, or any other fastening. You can use dressing.
[0023]
Further, the building accessory to which the floor structure according to the present invention is applied may be a balconi, a veranda, a terrace, a staircase outside an apartment house, an outer corridor of an apartment house, or an arbitrary building accessory. The floor structure according to the present invention can be applied.
[0024]
When the building accessory according to the present invention is a balconi, the floor member may be a deck material or a waterproof pan, and the present invention can be applied to a floor formed by an arbitrary floor member.
[0025]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The building attachment to which the floor structure according to the present embodiment is applied is a balconi, and FIG. 1 is a side view of the balconi 1.
[0026]
An arm member 3 protrudes from the outer wall 2A of the building 2, and a wife 5 which is a balconi structural material is coupled to the arm member 3 with bolts and nuts 4. In this way, there are a plurality of wife members 5 coupled to the outer wall 2A via the arm member 3 in the girder direction of the building 1 (in the direction orthogonal to FIG. 1 in the drawing), and between the adjacent member members 5 adjacent to each other. Further, a girder 6 which is a structural material of the balcony 1 is installed. A handrail 7 of the balcony 1 is erected on the end member 5 and the girder 6, thereby forming a contour structure of the balcony 1.
[0027]
The floor of the balconi 1 is formed by placing a deck material 11 which is a floor member on the joists 10, and FIG. 2 is a longitudinal sectional view showing a portion of the floor. A plurality of joists 10 serving as support members for supporting a plurality of deck members 11 thereon are arranged side by side in the direction of the girder of the building, in other words, in the longitudinal direction of the girder 6.
