Description

【０００１】
【発明の属する技術分野】
本発明は、住宅の和室と洋室の境界の床面段差部の気密構造に関する。
【０００２】
【従来の技術】
住宅の床の気密施工に際しては、例えば、互いに平行に大引きに架け渡された複数の根太間に断熱材を配置し、この断熱材の上面を防湿層で被覆した後、隣接する根太間に複数枚の床板を配置し、隣接する床板間の目地を気密テープで塞ぐようにしていた。
【０００３】
ところが、上記施工方法では、根太、断熱材及び床板等の床の各構成部材を順次別個に施工するので、施工に手間が掛かる問題がある。そこで、図１に示すように、複数配設された根太１と、隣接するこれら根太１間に配設された断熱材２と、前記根太１と前記断熱材２上に前記根太１と前記断熱材２が形成する矩形に対して水平方向へ突出した凸部４ａと没した凹部４ｂを形成するように固定された矩形の床板３とを具備して一体化された床パネル組立体４を製作しておき、この床パネル組立体４を隣接する大引き（図示せず）間に架け渡しながら、順次縦横に敷設して、床の施工作業を簡素化することが行われている。
【０００４】
【発明が解決しようとする課題】
ところで、上記のような床パネル組立体４を用いる場合、住宅の和室と洋室の境界線の床面段差部では、前記床パネル組立体４どうしの間と、前記凸部４ａ及び前記凹部４ｂにおける凹凸部の気密性をいかにして確保するかが問題となる。気密テープは平面以外の凹凸部などに隙間なく密着させて貼り付けることが困難である。一方、ウレタンを吹きつけて隙間を塞ぐことも行われていたが、この方法も十分に気密性を確保するまで至らないのが実情である。
【０００５】
本発明は、上記課題に鑑みてなされたものであって、本発明の目的は、床板と根太と断熱材とを一体化した床パネル組立体を用いた住宅の洋室と和室の床面段差部において、気密性を確保することができる構造を提供することである。
【０００６】

【００１０】
【発明の実施の形態】
以下、第１の実施の形態に係る和室と洋室の境界線における床面段差部の気密構造Ａについて図面に基づいて説明する。和室と洋室の境界線における床面段差部の気密構造Ａは、図１及び図２に示すように、複数配設された根太１と、隣接するこれら根太１間に配設された断熱材２と、前記根太１と前記断熱材２上に前記根太１と前記断熱材２が形成する矩形に対して水平方向へ突出した凸部４ａと没した凹部４ｂが形成されるように固定された矩形の床板３とを具備して一体化された床パネル組立体４を用いて床施工を行った場合に、図３に示すように、前記根太１の長手方向と平行となった間仕切壁下部５の和室と洋室の境界線における床面段差部の気密構造である。
【００１１】
前記床パネル組立体４は、前記凸部４ａと前記凹部４ｂを嵌合させると共に、大引き（図示せず）間に架け渡しながら、図３に示したように、順次縦横に敷設することにより、根太１、断熱材２及び床板３を同時に施工するためのものである。
【００１２】
洋室においては、前記床パネル組立体４については、通常、隣接する２辺に前記凸部４ａが、他の２辺に前記凹部が形成されたもの（床パネル組立体４Ａ）を使用し、図４に示すように、前記床パネル組立体４を大引き６の上に根太１の端部をビス６ａ等で固定する。
【００１３】
一方、和室においては、前記床パネル組立体４については、図５及び図６に示すような３辺に前記凸部４ａ、残りの１辺に前記凹部４ｂを具備したもの（床パネル組立体４Ｂ）を使用し、図７に示すように、大引き６の上に前記床板３の前記凸部４ａをビス等で固定する。この結果、洋室の床面より和室の床面の方が低い位置に設けられる。このように施工されるのは、畳厚さを確保し、和室へ畳が敷設された後に洋室、敷居、そして畳のいずれの高さをも等しくすることで室内に段差を形成しないようにするためである。
【００１４】
以下、和室と洋室の境界線における床面段差部の気密構造Ａについて詳細に説明する。根太１の長手方向と平行となる間仕切壁下部５（図３）の和室と洋室の境界線は、図８に示すように、洋室側の床パネル組立体４Ａの一端部と該洋室側の床パネル組立体４Ａより低い位置にある和室側の床パネル組立体４Ｂの一端部で形成されている。前記洋室側の床パネル組立体４Ａの一端部には、根太１ａが床板３ａよりその半分幅突設され、前記和室側の床パネル組立体４Ｂの一端部にも、根太１ｂが床板３ｂよりその半分幅突設されている。なお、前記床パネル組立体４Ａ、４Ｂの下面全体に断熱材が取付けられている。
【００１５】
まず、図９に示すように、洋室側の根太１ａと和室側の床板３ｂの端縁の間隔と略同じ厚さ且つ前記和室側の根太１ｂの上面と前記洋室側の根太１ａの上面の段差に相当する高さを有する側面板７を該上面が前記洋室側の根太１ａの上面と同一面になるように前記洋室側の根太１ａの側面に取付ける。次に、該側面板７と前記洋室側の根太１ａの上面に洋室側の床板３ａの一端と接続すると共に前記側面板７の和室側の側面７ａまで達する床板３ａと同厚の床帯板８を取付ける。
【００１６】
そして、前記床帯板８と洋室側の床板３ａの隙間、前記床帯板８と前記側面板７の隙間、及び前記側面板７と和室側の床板３ｂの隙間を各々気密テープ９で塞いで気密性を確保する。なお、前記床帯板８と前記側面板７を一体物とした断面逆Ｌ字形の棒材を前記床帯板８と前記側面板７の代わりに取付けることも考えられるが、この場合は、上記した前記床帯板８と前記側面板７の隙間に前記気密テープを貼り付ける必要がなくなるため、作業能率が向上する。
【００１７】
前記気密テープ９は、例えばアルミテープのように片面に粘着材が塗布されたものであって、前記床板３ａ、３ｂなどの被貼付け物の表面に隙間なく密着するものであればよい。
【００１８】
以下、第２の実施の形態に係る和室と洋室の境界線における床面段差部の気密構造Ｂについて図面に基づいて説明する。和室と洋室の境界線における床面段差部の気密構造Ｂは、第１の実施の形態に係る和室と洋室の境界線における床面段差部の気密構造Ａのところで説明した床パネル組立体４Ａ、４Ｂを用いて床施工を行った場合に、図３に示すように、前記根太１の長手方向と平行となる出入枠下部１０の和室と洋室の境界線における床面段差部の気密構造である。
【００１９】
以下、和室と洋室の境界線における床面段差部の気密構造Ｂについて詳細に説明する。根太１の長手方向と平行となる出入枠下部１０（図３）の和室と洋室の境界線は、図１０に示すように、洋室側の床パネル組立体４Ａの一端部と、該洋室側の床パネル組立体４Ａより低い位置に且つ敷居幅に対応した間隔を該床パネル組立体４Ａとの間にあけて設けられた和室側の床パネル組立体４Ｂの一端部で形成されている。前記洋室側の床パネル組立体４Ａの一端部には、根太１ａが床板３ａよりその半分幅突設され、前記和室側の床パネル組立体４Ｂの一端部にも、根太１ｂが床板３ｂよりその半分幅突設されている。なお、前記床パネル組立体４Ａ、４Ｂの下面全体に断熱材が取付けられている。
【００２０】
まず、図１１に示すように、和室側の根太１ｂの側面に該根太１ｂと洋室側の根太１ａとの間隔と略同じ厚さ且つ前記和室側の根太１ｂの側面と略同形状の和室敷居下地１１を前記和室側の前記根太１ｂの側面にビス等を用いて取付ける。
【００２１】
次に、前記和室敷居下地１１と前記和室側の根太１ｂの上面に和室側の床板３ｂと接続すると共に前記洋室側の根太１ａに達する床板３ｂと同厚の第２の床帯板１２を取付け、さらに、洋室側の根太１ａの上面に床板３ａと接続すると共に前記根太１ａの側面に達する床板３ａと同厚の第３の床帯板１３をビス等を用いて取り付ける。
【００２２】
そして、洋室側の床板３ａと第３の床帯板１３の隙間、前記第３の床帯板１３と洋室側の根太１ａの隙間、前記洋室側の根太１ａと前記第２の床帯板１２の隙間、及び前記第２の床帯板１２と前記和室側の床板３ｂの隙間を各々気密テープ９で塞ぐことにより気密性を確保し、最後に敷居１４を所定の箇所に取付ける。なお、該気密テープ９は、第１の実施の形態に係る和室と洋室の境界線における床面段差部の気密構造Ａのところで説明した気密テープ９と同じものである。
【００２３】
以下、第３の実施の形態に係る和室と洋室の境界線における床面段差部の気密構造Ｃついて図面に基づいて説明する。和室と洋室の境界線における床面段差部の気密構造Ｃは、第１の実施の形態に係る和室と洋室の境界線における床面段差部の気密構造Ａのところで説明した床パネル組立体４Ａ、４Ｂを用いて床施工を行った場合に、図３に示すように、前記根太１の長手方向と垂直となる間仕切壁下部１５の和室と洋室の境界線における床面段差部の気密構造である。
【００２４】
以下、和室と洋室の境界線における床面段差部の気密構造Ｃについて詳細に説明する。根太１の長手方向と垂直となる間仕切壁下部１５（図３）の和室と洋室の境界線は、図１２に示すように、洋室側の床パネル組立体４Ａの一端部と、該洋室側の床パネル組立体４Ａの一端部と相対向すると共に、これより低い位置にある和室側の床パネル組立体４Ｂの一端部で形成されている。前記洋室側の床パネル組立体４Ａの一端部には、床板３ａより複数の根太１の端部と断熱材２が突設されていると共にこれらが大引き６の上に固定されており、一方前記和室側の床パネル組立体４Ｂの一端部には、前記大引き６の上に固定された前記凸部４ａが形成されている。なお、前記床パネル組立体４Ａ、４Ｂの下面全体に断熱材が取付けられている。
【００２５】
まず、図１３に示すように、洋室側の前記床パネル組立体４Ａの床板３ａに接続する床板３ａと同厚の床板部１６ａと、和室側の床板３ｂの上面に当接する下地部１６ｂとを有する断面逆Ｌ字形の第１のＬ形材１６をビス等を用いて取付ける。この第１のＬ形材１６として、２枚の板材をビス及び接着剤等を用いて直角に接合したものが使用されているが、一体物でもよい。なお、第１のＬ形材１６が、前記したように２枚の板材から構成される場合は、これら板材の間においても気密性が保たれるようにしっかりと接着させる。
【００２６】
そして、前記洋室側の床板３ａと前記第１のＬ形材１６の隙間及び前記第１のＬ形材１６と和室側の床板３ｂの隙間を各々気密テープ９で塞ぐことにより、気密性を確保する。なお、該気密テープ９は、第１の実施の形態に係る和室と洋室の境界線における床面段差部の気密構造Ａのところで説明した気密テープ９と同じものである。
【００２７】
以下、第４の実施の形態に係る和室と洋室の境界線における床面段差部の気密構造Ｄついて図面に基づいて説明する。和室と洋室の境界線における床面段差部の気密構造Ｄは、第１の実施の形態に係る和室と洋室の境界線における床面段差部の気密構造Ａのところで説明した床パネル組立体４Ａ、４Ｂを用いて床施工を行った場合に、図３に示すように、前記根太１の長手方向と垂直となる出入枠下部１７の和室と洋室の境界線における床面段差部の気密構造である。
【００２８】
以下、和室と洋室の境界線における床面段差部の気密構造Ｄについて詳細に説明する。根太１の長手方向と垂直となる出入枠下部１７の和室と洋室の境界線は、図１４に示すように、洋室側の床パネル組立体４Ａの一端部と、該洋室側の床パネル組立体４Ａの一端部と相対向すると共に、これより低い位置にある和室側の床パネル組立体４Ｂの一端部で形成されている。前記洋室側の床パネル組立体４Ａの一端部には、床板３ａより複数の前記根太１の端部と前記断熱材２が突設されていると共にこれらが洋室側大引き６Ａの上に固定されており、前記和室側の床パネル組立体４Ｂの一端部には、和室側大引き６Ｂの上に固定された前記凸部４ａが形成されている。なお、前記床パネル組立体４Ａ、４Ｂの下面全体に断熱材が取付けられている。
【００２９】
まず、図１５に示すように、前記和室側大引き６Ｂと前記洋室側大引き６Ａの上を跨ぎ且つ和室側の床板３ｂに接続されると共に該上面と同一上面を有する第２の和室敷居下地１９をビス等を用いて取付ける。
【００３０】
次に、洋室側の前記床パネル組立体４Ａの床板３ａに接続する該床板３ａと同厚の床帯部１８ａと前記第２の和室敷居下地１９の上面に当接する下地部１８ｂとを有する断面逆Ｌ字形の第２のＬ形材１８をビス等を用いて取付ける。この第２のＬ形材１８として、２枚の板材をビス及び接着剤等を用いて直角に接合したものが使用されているが、一体物でもよい。なお、第２のＬ形材１８が、前記したように２枚の板材から構成される場合は、これら板材の間においても気密性が保たれるようにしっかりと接着させる。
【００３１】
そして、洋室側の床板３ａと前記第２のＬ形材１８の隙間、前記第２のＬ形材１８と前記第２の和室敷居下地１９の隙間、及び前記第２の和室敷居下地１９と前記和室側の床板３ｂの隙間を各々気密テープ９で塞ぐことにより気密性を確保し、最後に、敷居１４を所定の位置に取付ける。なお、該気密テープ９は、第１の実施の形態に係る和室と洋室の境界線における床面段差部の気密構造Ａのところで説明した気密テープ９と同じものである。

BACKGROUND OF THE INVENTION
The present invention relates to an airtight structure of a stepped portion on a floor surface at a boundary between a Japanese-style room and a Western-style room in a house.
[0002]
[Prior art]
In the airtight construction of the floor of the house, for example, a heat insulating material is arranged between a plurality of joists spanned in parallel with each other, and the upper surface of this heat insulating material is covered with a moisture-proof layer, and then between adjacent joists. A plurality of floor boards were arranged, and the joints between adjacent floor boards were sealed with an airtight tape.
[0003]
However, in the construction method described above, each component of the floor, such as joists, heat insulating materials, and floorboards, is constructed separately in order. Therefore, as shown in FIG. 1, a plurality of joists 1 are disposed, a heat insulating material 2 disposed between the adjacent joists 1, and the joists 1 and the heat insulation on the joists 1 and the heat insulating materials 2. A floor panel assembly 4 integrated with a rectangular floor board 3 fixed so as to form a convex part 4a projecting horizontally with respect to a rectangle formed by the material 2 and a depressed concave part 4b is manufactured. In addition, the floor construction work is simplified by laying the floor panel assembly 4 vertically and horizontally while spanning between adjacent large pulls (not shown).
