Description
【０００１】
【発明の属する技術分野】
本発明は木造並びに鉄骨造建築物の骨組み材の外側に連続して断熱を施す外張り断熱工法に関するものである。
【０００２】
【従来の技術】
従来から、外張り断熱通気工法が知られている。外張り断熱通気工法は、骨組材の外側に断熱材を釘等で仮止めし、更に窯業系サイディングや軽量気泡コンクリート薄型パネルなどの外壁材と断熱材との間に通気層が形成されるように、通気胴縁を配置してビスまたは釘で断熱材を貫通させて通気胴縁を骨組材に固定し、該通気胴縁上に外壁材を固定している（例えば特許文献１参照）。
【０００３】
しかし、上記の技術においては次のような欠点があった。即ち、通気胴縁に外壁材を固定し十分な支持力を得るために、通気胴縁を、断熱材を貫通させて骨組材に固定し構造的に安定させた後、更に外壁材を通気胴縁で固定する。そのため、ビス、釘等を数多く、しかも強固に固定する必要があり、結果として工期の遅延やコストアップの原因となる等の問題があった。さらに、通気胴縁を骨組材に固定する際、長いビスまたは釘を使用し、さらに仮止めは行われないため、ずれが生じやすく、施工精度が悪化するという欠点があった。
【０００４】
【特許文献１】
特開２００２−２４２３２４号
【０００５】
【発明が解決しようとする課題】
木造並びに鉄骨建築物において、断熱材を外張りで施工するに際し、外壁パネル、通気胴縁、断熱材を骨組材に容易にしかも施工精度よく固定できる外張り断熱通気工法を提供すること。
【０００６】
【課題を解決するための手段】
本発明者は、外張り断熱通気工法において、工法手順を工夫することにより、上記課題を解決しうることを見出し、本発明を完成した。本発明は下記のとおりである。
１．断熱材を骨組み材に仮止めし、外壁パネルに通気胴縁を仮止めして、その後、該外壁パネル表面から、釘、ビス、又はねじによって通気胴縁及び断熱材を貫通させて、骨組材へ外壁パネルを固定することを特徴とする外張り断熱通気工法。
２．断熱材が発泡プラスチック系断熱材であることを特徴とする１記載の外張り断熱通気工法。
３．外壁パネルとして軽量気泡コンクリート薄型パネルを用いることを特徴とする１又は２記載の外張り断熱通気工法。
【０００７】
ここで断熱材を仮止めするには、釘、両面接着テープ、接着剤等が用いられる。
通気胴縁を外壁パネルに仮止めするには釘、ビス、ねじ、ステープル等が用いられる。
使用する断熱材としては、発泡プラスチック系断熱材が好適に使用できる。
発泡プラスチック系断熱材としては、フェノールフォーム、ポリエチレンフォーム、スチレンフォーム（スチレンボード）、ポリウレタンフォーム（ウレタンボード）、ポリイソシアヌレートフォーム、塩化ビニールフォーム、ポリスチレンフォーム、ユリアフォーム等の合成樹脂発泡体から成る、板状の断熱材が好適に使用できる。
【０００８】
外壁パネルとしては釘、ビス、又はねじ留めできる物であれば良く、例えば軽量気泡コンクリート（以下、ＡＬＣという）外壁パネルを用いることにより、釘、ビス、ねじ打設の衝撃やねじ込みによるひび割れ防止、釘、ビス、又はねじ頭部の後仕上げが容易になる。
釘、ビス、又はねじ留めできるＡＬＣ薄型外壁パネルとしては、補強材としてメタルラス、鉄線及び溶接金網を用いたＡＬＣ薄型パネルが、釘、ビス、ねじ打設時の衝撃やビスにかかる力を分散させる点で好ましい。
【０００９】
ここにいうＡＬＣ薄型外壁パネルとは、厚み２０〜７５ｍｍで、補強材としてメタルラス、鉄線または溶接金網を用いたＡＬＣパネルをいう。そして、外壁材としてＡＬＣ薄型外壁パネルを用いることにより、より大きな支持力を得るために比較的径の大きな釘、ビス、ねじを用いてその外壁にめり込ませて固定しても、そのＡＬＣ薄型外壁パネル表面のビス穴は、建築用仕上塗材等によってそのＡＬＣ薄型外壁表面に防水仕上げを容易に行うことが出来るため、防水性や外観を悪化させることなく固定することができる。
さらに、断熱材を固定するための釘、ビス、ねじは、断熱材厚みによって、適した長さを選択する必要があるが、ＡＬＣの場合は、ＡＬＣ外壁パネルへのビスのめり込み深さを調節することで、断熱材厚みの変化を調整することが出来、部材を少品種化することができる。
【００１０】
【発明の実施の形態】
以下、本発明について、特にその好ましい態様を中心に、説明する。
図１は、本発明の木造建築物における外張り断熱通気工法の一例を示す模式図であり、６ａは骨組材（柱）、６ｂは骨組材（間柱）、４は断熱材、３は通気胴縁、２ａは釘、１は外壁材であるＡＬＣ薄型外壁パネル、５はビス、８は石膏ボード、９は建築用仕上塗材を示す。
【００１１】
この断熱材４を骨組み材６ａ、６ｂに釘２ａで仮止めし、次いで、外壁パネル１に通気胴縁３を釘２ａによって仮止めして、その後、該外壁パネル１表面から、ビス５によって通気胴縁３及び断熱材４を貫通させて、骨組材６ａ、６ｂへ外壁パネル１を固定する。通気胴縁３を外壁パネル１に仮止めするため、外壁パネル１をビス５によって骨組材に固定する際にずれが生じにくく、施工が良好になる。その後外壁材１表面のビス穴を建築用仕上塗材９によって防水仕上げを行う。
【００１２】
図２は、本発明の鉄骨建築物における外張り断熱通気工法の一例を示す模式図であり、２ｃは両面接着テープ、７は鉄骨骨組材、４は断熱材、３は通気胴縁、２ｂはステープル、１は外壁材であるＡＬＣ薄型外壁パネル、５はビスを示す。
この断熱材４を骨組み材７に両面接着テープ２ｃで仮止めし、次いで、外壁パネル１に通気胴縁３をステープル２ｂによって仮止めして、その後、該外壁パネル１表面から、ビス５によって通気胴縁３及び断熱材４を貫通させて、鉄骨骨組材７へ外壁パネル１を固定する。やはり通気胴縁３を外壁パネル１に仮止めするため、外壁パネル１をビス５によって骨組材に固定する際にずれが生じにくく、施工が良好になる。その後外壁材１表面のビス穴を建築用仕上塗材９によって防水仕上げを行う。
【００１３】
【発明の効果】
以上詳細に説明したように、本発明の外張り断熱通気工法は、断熱材、通気胴縁を貫通して、外壁パネルを木造、鉄骨建築物の骨組材に固定することにより、通気胴縁を骨組材へ強固に固定する必要がなくなるため、断熱施工がより容易に行える。
さらに、通気胴縁を外壁パネルに仮止めするため、外壁材を釘、ビス、又はねじによって骨組材に固定する際にずれが生じにくく、施工精度が良好になる。従って、外壁パネル、通気胴縁、断熱材を骨組材に容易にしかも施工精度よく固定できる。

BACKGROUND OF THE INVENTION
TECHNICAL FIELD The present invention relates to an outer-layer heat insulating method for continuously heat-insulating a frame material of a wooden structure or a steel structure building.
[0002]
[Prior art]
Conventionally, an outer heat insulating ventilation method has been known. The thermal insulation ventilation method of the outer layer temporarily fixes the heat insulating material with nails etc. on the outside of the frame material, and further, a ventilation layer is formed between the outer wall material such as ceramic siding and lightweight lightweight concrete thin panel and the heat insulating material. In addition, a ventilation trunk edge is disposed, a heat insulating material is penetrated with screws or nails, the ventilation trunk edge is fixed to the frame material, and an outer wall material is fixed on the ventilation trunk edge (see, for example, Patent Document 1).
[0003]
However, the above technique has the following drawbacks. That is, in order to fix the outer wall material to the ventilator edge and to obtain a sufficient support force, the ventilator edge is fixed to the frame material through the heat insulating material and is structurally stabilized. Secure with edges. For this reason, it is necessary to fix a large number of screws, nails, and the like firmly, resulting in problems such as a delay in the construction period and an increase in cost. Furthermore, when fixing the ventilator edge to the frame material, a long screw or nail is used, and further, temporary fixing is not performed.
[0004]

JP 2002-242324 A
[Problems to be solved by the invention]
To provide a thermal insulation ventilation method capable of easily fixing an outer wall panel, a ventilation trunk edge, and a thermal insulation material to a frame material with high construction accuracy when constructing the thermal insulation material in a wooden structure and a steel frame building.
[0006]
[Means for Solving the Problems]
The present inventor has found that the above-mentioned problems can be solved by devising the construction procedure in the outer-layer heat insulation ventilation method, and has completed the present invention. The present invention is as follows.
1. Temporarily fix the heat insulating material to the frame material, temporarily fix the ventilation trunk edge to the outer wall panel, and then penetrate the ventilation drum edge and the heat insulating material from the surface of the outer wall panel with nails, screws, or screws, Outer insulation ventilation method, characterized by fixing outer wall panels.
2. 2. The heat insulating aeration method according to
3. 3. The outer thermal insulation ventilation method according to 1 or 2, wherein a lightweight cellular concrete thin panel is used as the outer wall panel.
[0007]
Here, a nail, a double-sided adhesive tape, an adhesive, or the like is used to temporarily fix the heat insulating material.
Nails, screws, screws, staples or the like are used to temporarily fix the ventilator edge to the outer wall panel.
As the heat insulating material to be used, a foamed plastic heat insulating material can be suitably used.
The foamed plastic insulation is made of synthetic resin foam such as phenol foam, polyethylene foam, styrene foam (styrene board), polyurethane foam (urethane board), polyisocyanurate foam, vinyl chloride foam, polystyrene foam, urea foam. A plate-like heat insulating material can be preferably used.
[0008]
The outer wall panel only needs to be nail, screw, or anything that can be screwed. For example, by using a lightweight cellular concrete (hereinafter referred to as ALC) outer wall panel, it is possible to prevent cracking due to impact or screwing of nails, screws, screwing, Facilitates post finishing of nails, screws, or screw heads.
ALC thin panel that uses metal lath, iron wire and welded wire mesh as a reinforcing material to disperse impact and force applied to the nail, screw, screw, etc. This is preferable.
[0009]
The ALC thin outer wall panel as used herein refers to an ALC panel having a thickness of 20 to 75 mm and using a metal lath, iron wire, or welded wire mesh as a reinforcing material. And by using an ALC thin outer wall panel as the outer wall material, even if the outer wall is fixed by using a relatively large-diameter nail, screw, or screw to obtain a larger support force, the ALC The screw holes on the surface of the thin outer wall panel can be easily waterproofed on the surface of the ALC thin outer wall with an architectural finish coating material or the like, and therefore can be fixed without deteriorating the waterproof property and appearance.
In addition, for nails, screws, and screws for fixing the heat insulating material, it is necessary to select an appropriate length depending on the thickness of the heat insulating material. In the case of ALC, the depth of screw insertion into the ALC outer wall panel is adjusted. Thus, the change in the thickness of the heat insulating material can be adjusted, and the number of members can be reduced.
[0010]

[0013]
【The invention's effect】
As described above in detail, the outer insulation heat insulation ventilation method of the present invention penetrates the heat insulating material and the ventilation trunk edge, and fixes the outer wall panel to the frame material of the wooden or steel structure, thereby making the ventilation trunk edge. Since there is no need to firmly fix to the frame material, the heat insulation work can be performed more easily.
Furthermore, since the ventilator rim is temporarily fixed to the outer wall panel, the outer wall material is less likely to be displaced when the outer wall material is fixed to the frame material with nails, screws, or screws, and the construction accuracy is improved. Therefore, it is possible to easily fix the outer wall panel, the ventilator edge, and the heat insulating material to the frame material with high construction accuracy.
