Description

【０００１】
【発明の属する技術分野】
本発明は、躯体を構成する壁体の外壁面側に断熱材を有する外断熱構造体における建築構造又は工法に関する。
【０００２】
【従来の技術】
従来から、外断熱構造における建築工法が提案されている。この外断熱構造は、内断熱構造に対して以下のような特徴を備えている。まず、建物を支える躯体が断熱材の内側におかれるために、年間を通じて安定した温度条件下に躯体をおくことができる。従って、躯体の夏季の日射による熱膨張や冬季の放射冷却による収縮を防ぐことができる。また、断熱材が外側にあるために、躯体側で内部結露を生じることがない。更には、躯体によって室内の熱容量が大きくなるため、室温変動を少なくし、冷暖房効果を高めることができる。
【０００３】
【発明が解決しようとする課題】
しかし、このような特徴を備えた外断熱構造であっても、共通廊下やバルコニーやベランダなどのような壁面から外方向に突出した構造体を有する場合には、この構造体によって断熱欠損箇所を生じてしまう。壁面から外方向に突出した構造体を有する外断熱構造の側面断面図を図２９に示す。同図に示すように、外断熱構造は、建物を支える構造体部１が断熱材２の内側に設けられ、外壁部３の外面には断熱材２が設けられている。上記の従来の外断熱構造では、外壁部３の外部に設けられた壁面突出構造体４は、壁面突出構造体４が外壁部３と接する全断面で建物に保持されるため、断熱材２が壁面突出構造体４で分断され、大きな面積の断熱欠損部分を生じる。図２９の鎖線は、壁面突出構造体４周囲の温度分布の状態を示す等温線である。外気温度と室内温度との差が著しい時には、断熱欠損部分で熱橋が生じ、この熱橋によって壁面突出構造体４から外壁部３に熱移動が生じて建物の断熱性能が低下する。
【０００４】
そこで本発明は、断熱材が壁面突出構造体で分断される断熱欠損部を最小限にした建物を提供することを目的とする。また本発明は、断熱材が壁面突出構造体で分断される断熱欠損部を生じない建物を提供することを目的とする。

【０００６】
【発明の実施の形態】
本発明の第１の実施の形態による外断熱構造体における建築構造は、壁面突出構造部を、載置面を構成する積載部と、積載部を躯体に保持する保持部にて構成し、積載部と壁体との間に断熱層を介在させ、保持部を壁体に連結し、保持部と積載部とを一体に形成し、保持部を積載部の下面に突出させて形成したものである。このように壁面突出構造部の一部で壁体に保持するため、断熱材が分断される断熱欠損部は、壁面突出構造部の一部となり、建物の外壁面からの熱損失は少なくなり、躯体の断熱性能を向上させることができる。また、保持部と積載部とを同時に施工できるとともに、保持部を積載部の下面に突出させて形成することで、壁面突出構造部の保持のための強度を有しつつ、断熱材が分断される断熱欠損部をより小さくでき、建物の断熱性能を向上させることができる。
【０００７】
また本発明の第２の実施の形態は、第１の実施の形態による外断熱構造体における建築構造において、保持部を複数本の梁で構成し、壁体の壁面に平行な梁の断面を、幅寸法よりも高さ寸法を大きくしたものである。このため、壁面突出構造部の保持のための強度を必要とする部分のみで、壁面突出構造部は建物の構造体部に保持され、断熱材が分断される断熱欠損部も小さくでき、建物の断熱性能を向上させることができる。特に梁の断面を、幅寸法よりも高さ寸法を大きくすることで、積載部によって保持部に加わるモーメントを、少ない断面積で支持することができる。
【０００８】
また本発明の第３の実施の形態は、第１又は第２の実施の形態による外断熱構造体における建築構造において、保持部と積載部とをコンクリート材にて形成したものである。
【０００９】
また本発明の第４の実施の形態による外断熱構造体における建築構造は、保持部を鉄骨材とし、保持部を壁体にボルト結合したものである。このため、壁面突出構造部の保持のための強度を有しつつ、断熱材が分断される断熱欠損部をより小さくでき、建物の断熱性能を向上させることができる。
【００１０】
また本発明の第５の実施の形態は、第４の実施の形態による外断熱構造体における建築構造において、保持部と壁体との間に断熱パッキンを介在させたものである。このように壁面突出構造部と壁体とが断熱パッキンを介して保持されるため、壁面突出構造部によって断熱材が分断される断熱欠損部がほとんどなくなり、建物の断熱性能が向上する。
【００１１】
また本発明の第６の実施の形態による外断熱構造体における建築工法は、第１から第５の実施の形態による外断熱構造体における建築構造にて施工するものである。この施工方法によって壁面突出構造部と壁体とのほとんどが断熱材を介して保持されるため、壁面突出構造部によって断熱材が分断される断熱欠損部が少なくなり、躯体の断熱性能が向上する。
