Abstract
Description
この発明は木造軸組工法の建物が地震の揺れによって倒壊する事を防ぐ仕口に関するものである。 The present invention relates to a joint that prevents a wooden frame construction method from collapsing due to an earthquake.
我国の木造の建物である軸組工法で重層の建物は主要な部分の柱を、通し柱にしなけれ
ける為に断面の欠損を生じ地震の揺れによって通し柱が折れて建物が倒壊し貴重な生命、財産が失われてきた。よってこの部分を金物で補強したり、筋かいを入れて耐震性を向上させていた、しかしこれらの工法は現在の建築基準法に規定された耐震強度を守って建てられた建物でも阪神大震災クラスの地震で倒壊する危険性のある事が国土交通省の外郭団体、建材試験センターに設けられた「木質構造建築物の振動試験研究会」の実物実験でも明らかになっている。In the wooden construction method of our country's wooden building, the multi-story building must be the pillar of the main part as a through pillar.
As a result, the loss of the cross section occurred, the pillar was broken by the shaking of the earthquake, the building collapsed, and valuable life and property were lost. Therefore, this part was reinforced with hardware or a brace was added to improve earthquake resistance, but these construction methods were also built in the Hanshin Earthquake class even in buildings built with the seismic strength stipulated in the current Building Standards Act The fact that there is a risk of collapse due to an earthquake in the country has also been clarified in the actual experiment of the "vibration test study group of the wooden structure building" established in the building material test center of the Ministry of Land, Infrastructure, Transport and Tourism.
この発明は鋼製の一体化した仕口にする事により剛性を高めて通し柱が折れたり、横架材が脱落して建物が倒壊しない、安全で安心な木造軸組工法の建物を提供する事である。 This invention is to provide a safe and reliable building with a wooden frame construction method that does not break through the pillars by breaking through the pillars by falling into the integrated joint made of steel, or falling off the horizontal member. It is.
この発明は上階、下階の柱9を鋼製の箱1と柱9に挿入する丸鋼2で接いで通し柱を形成し丸鋼2が貫通した水平ダイアフラム4とで一体化した鋼製の仕口とする事により仕口に
る事なく通し柱に架構する為のガセットプレート3を鋼製の箱1に溶接して横架材10をボールト6とナット7で締め付ける事により強固に通し柱に取り付けられて、鋼製仕口と木製の柱9、横架材10を一体的な軸組とする手段を講じたものである。In the present invention, upper and lower pillars 9 are connected by a steel box 1 and a round steel 2 inserted into the pillar 9 to form a through pillar, and a steel diaphragm integrated with a horizontal diaphragm 4 through which the round steel 2 passes. By making it a joint
The
この発明はこのような手段を講じたので地震の揺れで通し柱が折れたり、横架材10が脱落せず、架構体が変形する事がない。したがって筋かいや各種補強材も正しい位置に保持出来る為、建物が倒壊する事が無く、人命や財産を守る事が出来る。しかも構造的にも簡単な仕口で有るので木部の施工が従来の工法と比べて容易である、また鋼製耐震仕口の本体は木部の中に隠れるので純和風の木造建物にも使用できるし、この発明は最上階の仕口にも応用できる。 Since the present invention employs such means, the through column is not broken by the shaking of the earthquake, the
この発明は鋼材と木材を最良の方法で接ぐ為に発明した工法である。その実施形態を図1に示す。この発明の一番の特徴は、柱9を接ぐのに鋼製の箱1のみで無く、柱9の中に丸鋼2を挿入する事である。そうする事で上階と下階の柱9を強度的に一体化させてなお且、鋼製の箱1で柱9を包みネジ付き釘8で固定する事で丸鋼2と柱9を同一化させた又、丸鋼が水平ダイアフラム4を貫通する事で丸鋼2の位置を固定し、施工性を良くすると共に水平ダイアフラム4に横架材10の水平応力を負担させる。尚、鋼材と木材をより強固に接着する為エポキシ系等の接着剤を用いればより一体化する。
次に横架材を取り付ける為に、ガセットプレート3を上下の鋼製の箱1の側面に溶接する、このガセットプレート3には横架材10を締め付ける為に、ボールト6を差込む穴を設ける。横架材10の断面に溝を設けてこの溝にガセットプレート3を差込み、ボールト6とナット7で締め付ける。This invention is a construction method invented to make the best contact between steel and wood. The embodiment is shown in FIG. The most characteristic feature of the present invention is that not only the steel box 1 but also the round steel 2 is inserted into the pillar 9 to contact the pillar 9. By doing so, the upper and lower pillars 9 are integrated with strength, and the steel box 1 is wrapped with the pillars 9 and fixed with
