Description

本発明は、表面に稜部と谷部とを交互に複数並設されたデッキプレート屋根又は折板屋根又は瓦棒屋根の何れかからなる屋根の上に、断熱パネルを載置して、前記屋根に対する固定金具を用いて前記断熱パネルを屋根に固定すると共に、その上方に防水層を設ける屋根断熱化方法に関する。   In the present invention, a heat insulating panel is placed on a roof made of either a deck plate roof, a folded plate roof, or a roof tile roof in which a plurality of ridges and valleys are alternately arranged on the surface. The present invention relates to a method for insulating a roof, in which the heat insulation panel is fixed to the roof using a fixing bracket for the roof, and a waterproof layer is provided above the heat insulation panel.

従来、この種の屋根断熱化方法としては、図11に示すように、前記断熱パネルPを、前記稜部6上に載置状態に配置し、断熱パネルPの上から、稜部6を目指して固定金具30をねじ込み、断熱パネルPを屋根rに固定して、その上から防水シート11等の防水層2を設置する方法を採っていた。
尚、この様な従来技術に関しては、当業者の間で広く知られているものであるが、該当する屋根断熱化方法に関して詳しく言及した特許文献などは見あたらないので、先行技術文献は示していない。
Conventionally, as this type of roof insulation method, as shown in FIG. 11, the heat insulation panel P is placed on the ridge portion 6 and the ridge portion 6 is aimed from above the heat insulation panel P. Then, the fixing bracket 30 is screwed in, the heat insulation panel P is fixed to the roof r, and the waterproof layer 2 such as the waterproof sheet 11 is installed thereon.
In addition, although such a prior art is widely known among those skilled in the art, since there is no patent document or the like that specifically refers to the applicable roof insulation method, no prior art document is shown. .

上述した従来の屋根断熱化方法によれば、前記断熱パネルを屋根に固定する際、屋根面の各稜部上にわたって載置された断熱パネルの上から、その下方に隠れた稜部を目指して固定金具をねじ込むことで実施されるから、図11(ロ)に示すように、稜部6に対する固定金具30のねじ込み位置が所定の位置からずれる危険性がある。そして、ねじ込み位置が狂うと、充分な固定強度が得られず、断熱パネルの固定に支障を来す問題がある。特に、稜部の幅寸法が小さい屋根に関してはその危険性が大きい。   According to the above-described conventional method for insulating a roof, when fixing the heat insulation panel to the roof, aiming at a ridge hidden under the heat insulation panel placed over each ridge on the roof surface. Since it is carried out by screwing the fixing bracket, there is a risk that the screwing position of the fixing bracket 30 with respect to the ridge portion 6 deviates from a predetermined position as shown in FIG. And if the screwing position goes wrong, sufficient fixing strength cannot be obtained, and there is a problem that hinders fixing of the heat insulating panel. In particular, the risk is high for a roof having a small ridge width.

従って、本発明の目的は、上記問題点を解消し、断熱パネルの固定をより確実に実施できる屋根断熱化方法を提供するところにある。   Accordingly, an object of the present invention is to provide a method for insulating a roof that can solve the above-mentioned problems and can more reliably fix the heat insulation panel.

本発明の第1の特徴構成は、表面に稜部と谷部とを交互に複数並設されたデッキプレート屋根又は折板屋根又は瓦棒屋根の何れかからなる屋根の上に、断熱パネルを載置して、前記屋根に対する固定金具を用いて前記断熱パネルを屋根に固定すると共に、その上方に防水層を設ける屋根断熱化方法において、前記断熱パネルの設置に当たって、予め、前記固定金具を前記屋根の稜部に上方に突出する状態に取り付け、前記断熱パネルに食い込み可能な食い込み部を前記固定金具の下端側に設けておき、それらの上から前記断熱パネルを載置すると共に、前記固定金具が断熱パネルの下面から上方へ突き刺さる状態に前記断熱パネルを押し下げて、その押し下げに伴って前記食い込み部を前記断熱パネルに下から食い込ませて前記固定金具周囲の断熱パネル部分を厚み方向に圧密させて設置するところにある。 A first characteristic configuration of the present invention is that a heat insulating panel is provided on a roof made of either a deck plate roof, a folded plate roof, or a roof tile roof in which a plurality of ridges and valleys are alternately arranged on the surface. In the roof thermal insulation method of mounting and fixing the heat insulating panel to the roof using a fixing bracket for the roof, and providing a waterproof layer above the roof, the fixing bracket is attached in advance to the installation of the heat insulating panel. Attach a state protruding upward in the ridge of the roof, the biting portion capable bite into the insulating panel may be provided on the lower side of the fixing bracket, with mounting the insulation panel over them, the the press down on the insulating panel in a state where the fixing bracket pierce upward from the lower surface of the insulation panel, the fixing bracket around by bite from under the biting portion to the insulating panel with the depressed its It is at the installation by the insulation panel portion was compacted in a thickness direction.

本発明の第1の特徴構成によれば、前記断熱パネルの設置に当たって、予め、前記固定金具を前記屋根の稜部に上方に突出する状態に取り付けておくから、固定金具の位置ずれの無い状態に目で確認して固定作業を進められる。その結果、より精度よく固定金具を屋根面の各稜部に取り付けることができるようになり、所定の固定強度を確保することが可能となる。この作用効果は、稜部幅寸法の大小に拘わらず期待することが可能となり、色々な寸法の屋根に広く適用させることができる。
更には、上述のように固定金具が固定された屋根の上から、前記断熱パネルを載置すると共に、前記固定金具が断熱パネルの下面から上方へ突き刺さる状態に前記断熱パネルを押し下げて設置するから、固定金具が突き刺さった断熱パネル部分の周囲は、固定金具との摩擦力によって上方へ盛り上がる状態に変形することはあっても、下方に凹むことが防止され易く、後工程で実施される防水層上に水溜まりが発生し難い状態に固定することが可能となる。因みに、防水層上に水溜まりが発生すると、防水層の劣化の原因になり易いから、防水層の下地に凹みが生じることは好ましくない。
また、屋根に取り付けられた断熱パネルには、例えば、風による押圧力や揚圧力等の外力が作用するから、飛ばされないようにするために安定した状態に固定する必要があり、固定金具を使用して屋根に固定されているが、その固定金具周囲の断熱パネル部分には、大きな力が特に集中する危険性がある。
本発明の第1の特徴構成によれば、圧密によって断熱パネルの被固定部分の強度向上を図ることが可能となり、前記固定金具によって、より安定した状態に断熱パネルを固定することが可能となる。
According to the first characteristic configuration of the present invention, when the heat insulating panel is installed, the fixing bracket is attached in a state of protruding upward to the ridge portion of the roof in advance, so that the fixing bracket is not displaced. The fixing work can be advanced with visual confirmation. As a result, the fixing bracket can be attached to each ridge of the roof surface with higher accuracy, and a predetermined fixing strength can be ensured. This effect can be expected regardless of the size of the ridge width, and can be widely applied to roofs of various sizes.
Furthermore, since the heat insulation panel is placed from above the roof on which the fixing metal fitting is fixed as described above, and the heat insulation panel is pushed down and installed in a state where the fixing metal metal sticks upward from the lower surface of the heat insulation panel. Even if the heat insulation panel portion where the fixing bracket is pierced may be deformed to rise upward due to the frictional force with the fixing bracket, it is easy to prevent it from being dented downward, and the waterproof layer is implemented in a later process It becomes possible to fix to a state where a water pool is unlikely to be generated on the top. Incidentally, when a water pool is generated on the waterproof layer, the waterproof layer is likely to be deteriorated. Therefore, it is not preferable that the dent is formed on the base of the waterproof layer.
In addition, the heat insulation panel attached to the roof is subjected to external forces such as the pressing force and lifting pressure caused by the wind, so it is necessary to fix it in a stable state so that it will not be blown off. Although it is fixed to the roof, there is a risk that a large force is particularly concentrated on the heat insulating panel around the fixing bracket.
According to the first characteristic configuration of the present invention, it is possible to improve the strength of the fixed portion of the heat insulating panel by compaction, and it is possible to fix the heat insulating panel in a more stable state by the fixing bracket. .

本発明の第2の特徴構成は、前記屋根の稜部に上方に突出状態に取り付けられた前記固定金具に、取り付けることで上方への突出長さが増加する延長部材を取り付けた状態で前記断熱パネルを押し下げて設置するところにある。   According to a second characteristic configuration of the present invention, the heat insulation is performed in a state in which an extension member that increases an upward projecting length is attached to the fixing bracket attached to the ridge portion of the roof in an upward projecting state. It is in the place where the panel is pushed down.

本発明の第2の特徴構成によれば、固定金具の長さが前記断熱パネルの厚み寸法より短く設定されていても、固定金具に取り付けた前記延長部材が断熱パネルを貫通(又はほぼ貫通)する状態となり、設置した断熱パネルの上方から固定金具の位置を一目瞭然に確認することが可能となる。そして、前記延長部材を取り外して断熱パネルの本固定を行えばよく、断熱パネル固定作業等の後工程を効率よく実施することが可能となる。また、固定金具そのものの長さを断熱パネルの厚み寸法より短く設定できるようになることで、断熱パネルの固定箇所の盛り上がりを抑えることができ、その上に設置される防水層の平坦性を向上させることができると共に、断熱化屋根としての意匠性の向上を図ることが可能となる。   According to the second characteristic configuration of the present invention, even if the length of the fixing bracket is set shorter than the thickness dimension of the heat insulating panel, the extension member attached to the fixing bracket penetrates (or substantially penetrates) the heat insulating panel. It becomes possible to confirm the position of the fixing bracket at a glance from above the installed heat insulating panel. Then, it is only necessary to remove the extension member and perform the main fixing of the heat insulating panel, and it is possible to efficiently carry out post-processes such as a heat insulating panel fixing operation. In addition, the length of the fixing bracket itself can be set shorter than the thickness dimension of the heat insulation panel, so that the rise of the fixing part of the heat insulation panel can be suppressed, and the flatness of the waterproof layer installed on it is improved. It is possible to improve the design as a heat insulating roof.

本発明の第3の特徴構成は、前記固定金具として、屋根に対して基端部を取り付けるボルト体と、そのボルト体の先端部に取り付けて前記断熱パネルを抑え固定可能な抑え体とを備えて構成したものを使用し、前記ボルト体は、屋根の上方から基端部を屋根に挿入して締結操作可能なワンサイドボルトを使用するところにある。   A third characteristic configuration of the present invention includes, as the fixing bracket, a bolt body that attaches a base end portion to a roof, and a restraining body that can be attached to a distal end portion of the bolt body and can hold and fix the heat insulating panel. The bolt body uses a one-side bolt that can be fastened by inserting a base end portion into the roof from above the roof.

本発明の第3の特徴構成によれば、本発明の第1〜2の特徴構成による上述の作用効果を叶えることができるのに加えて、屋根の上面からの施工のみで、固定金具取付作業や、断熱パネル固定作業を実施することが可能となり効率よく作業を進めることが可能となる。
そして、屋根断熱化施工に伴って屋根の下方空間への頻繁な立ち入りを行わずに一連の作業を実施することができるから、屋根の下方空間を開放した施工が可能となる。これは、新築においては、屋根の下方空間では、例えば、間仕切り工事や内装工事等の他の作業を、屋根断熱化施工と並行して進めることができる効果があり、既存建物を対象とした改修においては、建物を今まで通り使用しながら、屋根断熱化施工を進めることができる効果がある。
According to the third characteristic configuration of the present invention, in addition to being able to achieve the above-described operational effects according to the first and second characteristic configurations of the present invention, the fixing bracket mounting operation can be performed only by construction from the top surface of the roof. In addition, it is possible to carry out the fixing operation of the heat insulation panel, and it is possible to efficiently perform the operation.
And since a series of work can be implemented without performing frequent access to the lower space of the roof with the roof insulation construction, the construction that opens the lower space of the roof becomes possible. In new construction, in the space below the roof, for example, there is an effect that other work such as partitioning work and interior work can be carried out in parallel with the roof insulation construction work. Has the effect of being able to proceed with the heat insulation construction while using the building as before.

以下に本発明の実施の形態を図面に基づいて説明する。尚、図面において従来例と同一の符号で表示した部分は、同一又は相当の部分を示している。   Embodiments of the present invention will be described below with reference to the drawings. In the drawings, the parts indicated by the same reference numerals as in the conventional example indicate the same or corresponding parts.

従って、前記屋根rは、表面に稜部6と谷部7とが交互に複数並設された形状に形成されている。
As shown in FIG. 2, the roof r is disposed on a trapezoidal mountain-shaped tight frame 4 attached to a main building 3 made of a steel shape so that both side edges of each folded plate 5 overlap each other. Integration is achieved by bolting the combined ridges 6 to the tight frame 4. The folded plate 5 is formed such that the ridges 6 are located at both ends in the width direction, and the valleys 7 are located between the ridges 6.
Accordingly, the roof r is formed in a shape in which a plurality of ridges 6 and valleys 7 are alternately arranged on the surface.

一方、前記稜部6には、上方に突出する状態にボルト体8が取り付けられ、そのボルト体8と、そのボルト体8の先端部に取り付けられた抑え体9とによって前記断熱パネルPが固定されている。   On the other hand, a bolt body 8 is attached to the ridge portion 6 so as to protrude upward, and the heat insulating panel P is fixed by the bolt body 8 and a holding body 9 attached to the tip of the bolt body 8. Has been.

前記ボルト体8は、図3に示すように、所謂「ワンサイドボルト」であり、予め、稜部6に形成しておいた取付用ボルト穴6a内に、下端部を挿入した状態で、専用工具を用いて突出部8aを回転操作すると、下端部に備えてあるクサビ8bによって、座金部8cが拡径し、前記取付用ボルト穴6aの裏面側穴周囲に張り出して当接することで抜け止めを図るように構成されている。また、突出部8aには、ナット部材8dが螺合させてあり、拡径した座金部8cとこのナット部材8dとで、前記折板5の稜部6を挟持している。
また、前記ナット部材8dが螺合されている部分には、合成樹脂製の水密向上カバー10が被せてある。この水密向上カバー10は、外径が円錐形に形成してある。
As shown in FIG. 3, the bolt body 8 is a so-called “one-side bolt”, and is used in a state where a lower end portion is inserted into a mounting bolt hole 6 a formed in the ridge portion 6 in advance. When the projecting portion 8a is rotated by using a tool, the washer portion 8c is expanded in diameter by the wedge 8b provided at the lower end portion, and is prevented from coming off by protruding around the back side hole of the mounting bolt hole 6a. It is comprised so that it may aim. Further, a nut member 8d is screwed into the projecting portion 8a, and the ridge portion 6 of the folded plate 5 is sandwiched between the washer portion 8c having an enlarged diameter and the nut member 8d.
Further, a watertight improvement cover 10 made of synthetic resin is put on a portion where the nut member 8d is screwed. This watertight cover 10 has an outer diameter formed in a conical shape.

前記抑え体9は、金属で構成してあり、前記ボルト体8の突出部8aに螺合する雌ネジボルト9Aと、雌ネジボルト9Aの胴部分9Aaが挿通する挿通孔9Baを備えた抑え板9Bとを備えて構成してある。
そして、前記断熱パネルPの固定は、前記ボルト体8の突出部8aが貫通する状態に配置された断熱パネルPの上から、前記抑え板9Bを載置すると共に、挿通孔9Baに雌ネジボルト9Aを挿通させながらボルト体8に螺合させて締め付けることにより、雌ネジボルト9Aの拡径頭部9Abが抑え板9Bの挿通孔9Ba周りを押さえ、その結果、抑え板9Bが、断熱パネルPの上面を前記屋根rの稜部6との間で挟持することができ、安定的な固定を叶えることが可能となる。
また、上述の断熱パネル取付状態のまま、それらの上から防水シート11を被せ、前記抑え板9Bの上面に接着することで、安定した状態に防水層2を形成することができる。
The holding body 9 is made of metal, and includes a female screw bolt 9A that is screwed into the protruding portion 8a of the bolt body 8, and a holding plate 9B that includes an insertion hole 9Ba through which the body portion 9Aa of the female screw bolt 9A is inserted. It is configured with.
The heat insulating panel P is fixed by placing the holding plate 9B on the heat insulating panel P arranged in a state where the protruding portion 8a of the bolt body 8 penetrates, and the female screw bolt 9A in the insertion hole 9Ba. As a result, the enlarged diameter head portion 9Ab of the female screw bolt 9A presses around the insertion hole 9Ba of the restraining plate 9B, and as a result, the restraining plate 9B is attached to the upper surface of the heat insulating panel P. Can be held between the ridges 6 of the roof r and stable fixing can be achieved.
Moreover, the waterproof layer 2 can be formed in a stable state by covering the waterproof sheet 11 from above and attaching the waterproof sheet 11 to the upper surface of the holding plate 9B with the above-described heat insulating panel attached.

尚、前記断熱パネルPは、合成樹脂製の発泡体で構成されており、前記ボルト体8の突出部8aが貫通する程度の柔らかさを備えている。そして、当該断熱パネルPを屋根r上へ配置する際には、予め、前記ボルト体8は稜部6に設置されているから、それらの上から前記断熱パネルPを載置すると共に、前記突出部8aが断熱パネルPの下面から上方へ突き刺さる状態に前記断熱パネルPを押し下げることで実施できる。
そして、断熱パネルPを押し下げる際には、ボルト体8周囲の断熱パネル部分Paは、円錐形の前記水密向上カバー10が下方から食い込むことで他の部分より厚み方向に圧密され、その結果、その部分の強度が上がり、より安定した状態に固定することが可能となっている。即ち、前記水密向上カバー10は、屋根rの固定金具取付部の水密性の向上を図ることができると共に、断熱パネルPの被固定箇所の強度アップを促進する作用をも備えている(図3(ハ)参照)。
In addition, the said heat insulation panel P is comprised with the foam made from a synthetic resin, and is provided with the softness of the grade which the protrusion part 8a of the said bolt body 8 penetrates. And when arrange | positioning the said heat insulation panel P on the roof r, since the said bolt body 8 is installed in the ridge part 6 previously, while mounting the said heat insulation panel P from them, the said protrusion This can be carried out by pushing down the heat insulation panel P so that the portion 8a sticks upward from the lower surface of the heat insulation panel P.
And when pushing down the heat insulation panel P, the heat insulation panel part Pa around the bolt body 8 is consolidated in the thickness direction from the other parts by the conical watertight improvement cover 10 biting in from below, and as a result, The strength of the portion is increased, and the portion can be fixed in a more stable state. That is, the water-tightness improvement cover 10 can improve the water-tightness of the fixing bracket mounting portion of the roof r and also has an action of promoting an increase in strength of the fixed portion of the heat-insulating panel P (FIG. 3). (See (c)).

屋根断熱化方法の手順を説明する。尚、当該屋根断熱化方法は、既存の屋根rの断熱改修によって断熱屋根Rを形成することのみならず、新築による断熱屋根Rの形成にも適用することができる。
[1] 形成された屋根rの稜部6の所定位置に取付用ボルト穴6aを形成すると共に、そのボルト穴6aに、ボルト体8を取り付ける(図3(イ)参照)。その際、水密向上カバー10も取り付けておく。
[2] 屋根r上に断熱パネルPを配置して、前記ボルト体8の突出部8aが断熱パネルPの下面から上に突き刺さるように断熱パネルPを押さえる(図3(ロ)参照)。そして、断熱パネルPの下面が稜部6の上面に当接する程度まで下げる。この行為によって、水密向上カバー10がボルト体8周りの断熱パネル部分Paに下から食い込んで、断熱パネル厚み方向に圧密することができ、固定強度を向上させることができる(図3(ハ)参照)。
[3] ボルト体8に抑え体9を螺合させて断熱パネルPを固定する。
[4] 断熱パネルの上から防水シート11を敷設し、前記抑え体9に接着することで防水層2を形成する(図1参照)。抑え体9への防水シート11の接着は、例えば、接着材の塗布によって実施する方法や、予め、抑え体9の上面にホットメルト接着層を設けておき、被せた防水シート11の上方から、磁気誘導加熱によって抑え体9を加熱し、その熱で溶けたホットメルト接着層によって接着する等の方法を採用することができる。
The procedure of the roof insulation method will be described. In addition, the said roof heat insulation method can be applied not only to forming the heat insulation roof R by heat insulation repair of the existing roof r, but also to formation of the heat insulation roof R by new construction.
[1] The mounting bolt hole 6a is formed at a predetermined position of the ridge 6 of the formed roof r, and the bolt body 8 is attached to the bolt hole 6a (see FIG. 3 (A)). At that time, a watertight cover 10 is also attached.
[2] The heat insulation panel P is arranged on the roof r, and the heat insulation panel P is pressed so that the projecting portion 8a of the bolt body 8 sticks upward from the lower surface of the heat insulation panel P (see FIG. 3B). And it lowers to such an extent that the lower surface of the heat insulation panel P contact | abuts on the upper surface of the ridge part 6. FIG. By this action, the watertight improvement cover 10 can bite into the heat insulation panel portion Pa around the bolt body 8 from below and can be consolidated in the heat insulation panel thickness direction, and the fixing strength can be improved (see FIG. 3 (C)). ).
[3] The heat insulating panel P is fixed by screwing the holding body 9 onto the bolt body 8.
[4] The waterproof sheet 11 is laid from the top of the heat insulating panel and bonded to the holding body 9 to form the waterproof layer 2 (see FIG. 1). Adhesion of the waterproof sheet 11 to the restraining body 9 is performed, for example, by a method of applying an adhesive or by previously providing a hot melt adhesive layer on the upper surface of the restraining body 9 and from above the waterproof sheet 11 covered. A method of heating the suppressing body 9 by magnetic induction heating and bonding with the hot melt adhesive layer melted by the heat can be adopted.

本実施形態の屋根断熱技術によれば、固定金具の位置ずれの無い状態に目で確認して固定作業を進められ、より精度よく固定金具を屋根面の各稜部に取り付けることができる。従って、稜部幅寸法の大小に拘わらず、所定の固定強度をより確実に確保することが可能となる。また、断熱パネルの固定作業をも効率よく実施することが可能となる。   According to the roof heat insulation technology of the present embodiment, the fixing work can be proceeded by visually confirming that the fixing metal is not displaced, and the fixing metal can be attached to each ridge of the roof surface with higher accuracy. Therefore, it is possible to ensure a predetermined fixing strength more reliably regardless of the size of the ridge width. In addition, the fixing operation of the heat insulation panel can be performed efficiently.

〔第2実施形態〕
図4は、本発明の屋根断熱化方法の第2実施形態の施工によって断熱化が図られた断熱屋根Rを示している。
当該実施形態においては、断熱屋根Rは、折板屋根で構成された屋根rの上に、断熱パネルPを載置して、前記屋根rに対する固定金具1を用いて前記断熱パネルPを屋根rに固定すると共に、その上方に防水層2を設けて構成されている。
[Second Embodiment]
FIG. 4 shows a heat insulating roof R in which heat insulation is achieved by the construction of the second embodiment of the roof heat insulating method of the present invention.
In the present embodiment, the heat insulating roof R is configured such that the heat insulating panel P is placed on the roof r composed of the folded plate roof, and the heat insulating panel P is mounted on the roof r using the fixing bracket 1 for the roof r. And a waterproof layer 2 is provided above it.

前記屋根rは、図5に示すように、丸ハゼ継ぎの折板屋根で構成されており、形鋼からなる母屋3に取り付けた台形山型形状のタイトフレーム4上に、緊定金具17が取り付けられ、その緊定金具17を二枚の折板5のハゼ継ぎ部18に介在させて一体化が図られている。ハゼ継ぎ部18での緊定金具17の一体化は、例えば、緊定金具17を、接続する互いの折板5の両側縁部で挟んだ状態で電動締め機で巻き込んで締めることで実施することができる。そして、前記屋根rは、表面に稜部6と谷部7とが交互に複数並設された形状に形成されており、ハゼ継ぎ部18は、稜部6に位置している。
因みに、当該実施形態のようなハゼ継ぎの折板屋根を対象とした屋根断熱化方法は、従来、図12に示すように、補強用のベースプレート12を稜部6にビス止めしておき、そのベースプレート12上に断熱パネルPを載置し、断熱パネルPの上から、ベースプレート12を目指して固定金具30をねじ込み、断熱パネルPを屋根rに固定して、その上から防水シート11等の防水層2を設置する方法と採っていたが、固定金具30が、屋根rを傷つけ易く、防水性や強度の低下をまねく危険性があった。
As shown in FIG. 5, the roof r is formed of a folded-plate roof with a round goby joint. On the trapezoidal chevron-shaped tight frame 4 attached to the main building 3 made of shaped steel, a fastening bracket 17 is provided. The fasteners 17 are attached and integrated by interposing the goose joints 18 of the two folded plates 5. Integration of the tightening bracket 17 at the seam joint 18 is carried out, for example, by winding the tightening bracket 17 with an electric fastening machine while being clamped between both side edges of the folded plates 5 to be connected. be able to. The roof r is formed in a shape in which a plurality of ridges 6 and valleys 7 are alternately arranged in parallel on the surface, and the seam joint 18 is located on the ridge 6.
Incidentally, the roof thermal insulation method for the folded-plate roof of the seam joint as in the present embodiment has been conventionally screwed to the ridge 6 with the reinforcing base plate 12 as shown in FIG. The heat insulating panel P is placed on the base plate 12, and the fixing bracket 30 is screwed toward the base plate 12 from above the heat insulating panel P to fix the heat insulating panel P to the roof r. Although the method of installing the layer 2 was adopted, there was a risk that the fixing metal 30 easily damages the roof r, resulting in a decrease in waterproofness and strength.

これに対して、本実施形態の場合、前記稜部6には、前記ハゼ継ぎ部18に挟持状態に取り付けられたボルト体8が上方に突出する状態に設けられており、そのボルト体8と、そのボルト体8の先端部に取り付けられた抑え体9とによって前記断熱パネルPが固定されている。   On the other hand, in the case of this embodiment, the ridge portion 6 is provided with a bolt body 8 attached to the gouge joint portion 18 so as to protrude upward. The heat insulating panel P is fixed by a holding body 9 attached to the tip of the bolt body 8.

前記ボルト体8は、図6に示すように、前記ハゼ継ぎ部18を両側方から挟持することで嵌合する挟持片部19と、前記挟持片部19を挟持操作自在なボルト20aとナット20bからなる挟持ネジ部材20と、下端部が平板形状に形成された所謂『羽子板ボルト21』とを備えて構成されている。そして、羽子板ボルト21は、前記挟持片部19の上面部に、ボルト部21aを下方から挿通させて突出する状態にしてあると共に、下端の平板部21bを、両挟持片部19間に位置させた状態で、前記平板部21bのボルト挿通孔21cに、前記挟持ネジ部材20のボルト20aを挿通させて一体的に固定されている。   As shown in FIG. 6, the bolt body 8 includes a clamping piece portion 19 that is fitted by clamping the gouge joint portion 18 from both sides, and a bolt 20 a and a nut 20 b that are capable of clamping the clamping piece portion 19. And a so-called “wing plate bolt 21” having a lower end formed in a flat plate shape. And the battledore bolt 21 has a bolt part 21a inserted into the upper surface part of the clamping piece part 19 from below and protrudes, and a flat plate part 21b at the lower end is positioned between the clamping piece parts 19. In this state, the bolt 20a of the clamping screw member 20 is inserted into the bolt insertion hole 21c of the flat plate portion 21b and fixed integrally.

前記抑え体9は、金属で構成してあり、前記ボルト体8のボルト部21aに螺合する雌ネジボルト9Aと、雌ネジボルト9Aの胴部分9Aaが挿通する挿通孔9Baを備えた抑え板9Bとを備えて構成してある。
そして、前記断熱パネルPの固定は、前記ボルト体8のボルト部21aが貫通する状態に配置された断熱パネルPの上から、前記抑え板9Bを載置すると共に、挿通孔9Baに雌ネジボルト9Aを挿通させながらボルト体8に螺合させて締め付けることにより、雌ネジボルト9Aの拡径頭部9Abが抑え板9Bの挿通孔9Ba周りを押さえ、その結果、抑え板9Bが、断熱パネルPの上面を前記屋根rの稜部6との間で挟持することができ、安定的な固定を叶えることが可能となる。
また、上述の断熱パネル取付状態のまま、それらの上から防水シート11を被せ、前記抑え板9Bの上面に接着することで、安定した状態に防水層2を形成することができる。
The holding body 9 is made of metal and includes a female screw bolt 9A that is screwed into the bolt portion 21a of the bolt body 8, and a holding plate 9B that includes an insertion hole 9Ba through which the body portion 9Aa of the female screw bolt 9A is inserted. It is configured with.
Then, the heat insulating panel P is fixed by placing the holding plate 9B on the heat insulating panel P arranged in a state where the bolt part 21a of the bolt body 8 penetrates, and the female screw bolt 9A in the insertion hole 9Ba. As a result, the enlarged diameter head portion 9Ab of the female screw bolt 9A presses around the insertion hole 9Ba of the restraining plate 9B, and as a result, the restraining plate 9B is attached to the upper surface of the heat insulating panel P. Can be held between the ridges 6 of the roof r and stable fixing can be achieved.
Moreover, the waterproof layer 2 can be formed in a stable state by covering the waterproof sheet 11 from above and attaching the waterproof sheet 11 to the upper surface of the holding plate 9B with the above-described heat insulating panel attached.

尚、前記断熱パネルPは、合成樹脂製の発泡体で構成されており、前記ボルト体8のボルト部21aが貫通する程度の柔らかさを備えている。そして、当該断熱パネルPを屋根r上へ配置する際には、予め、前記ボルト体8は稜部6のハゼ継ぎ部18に挟持固定されているから、それらの上から前記断熱パネルPを載置すると共に、前記ボルト部21aが断熱パネルPの下面から上方へ突き刺さる状態に前記断熱パネルPを押し下げることで実施できる。
そして、当該実施形態においては、ボルト体8の高さ寸法は、設置した断熱パネルPの上面より下方に位置するように短めに設定してあることから、ボルト体8が断熱パネルPに突き刺さった状態では貫通せず、断熱パネルP上から抑え体9を取り付ける位置を確認できない為、予め、ボルト部21aに図に示すように長めの金属筒(延長部材に相当)22を外嵌させておき、そのまま、断熱パネルPを押し下げる。そして、断熱パネルP上に突出した金属筒22の上端を持って引き抜いた後に、抑え体9、及び、雌ネジボルト9Aを設置する方法で実施できる。因みに、ボルト体8の高さ寸法を短めに設定してあることで、断熱パネルP上へ突出する固定金具1の高さを少なくして、防水層2をより平坦に設置できる。
In addition, the said heat insulation panel P is comprised with the foam made from a synthetic resin, and is provided with the softness of the grade which the bolt part 21a of the said bolt body 8 penetrates. And when arrange | positioning the said heat insulation panel P on the roof r, since the said bolt body 8 is previously clamped and fixed to the gouge joint part 18 of the ridge part 6, the said heat insulation panel P is mounted from them. It can be implemented by pushing down the heat insulation panel P in a state where the bolt part 21a pierces upward from the lower surface of the heat insulation panel P.
And in the said embodiment, since the height dimension of the bolt body 8 was set short so that it might be located below the upper surface of the installed heat insulation panel P, the bolt body 8 pierced the heat insulation panel P. Since it does not penetrate in the state and the position where the holding body 9 is attached from the top of the heat insulating panel P cannot be confirmed, a long metal tube (corresponding to an extension member) 22 is externally fitted in advance to the bolt portion 21a as shown in the figure. The heat insulation panel P is pushed down as it is. And it can implement by the method of installing the control body 9 and the internal thread bolt 9A, after pulling out the upper end of the metal cylinder 22 protruding on the heat insulation panel P. Incidentally, since the height dimension of the bolt body 8 is set to be short, the height of the fixing bracket 1 protruding onto the heat insulating panel P can be reduced, and the waterproof layer 2 can be installed more flatly.

屋根断熱化方法の手順を説明する。尚、当該屋根断熱化方法は、既存の屋根rの断熱改修によって断熱屋根Rを形成することのみならず、新築による断熱屋根Rの形成にも適用することができる。
[1] 形成された屋根rのハゼ継ぎ部18の所定位置に、前記挟持片部19、挟持ネジ部材20、羽子板ボルト21からなるボルト体8を取り付ける(図6(イ)(ロ)参照)。
[2] 羽子板ボルト21のボルト部21aに金属筒22を外嵌させた状態で(図6(ハ)参照)、屋根r上に断熱パネルPを配置して、前記ボルト体8のボルト部21a及び金属筒22が断熱パネルPの下面から上に突き刺さるように断熱パネルPを押さえる(図6(ニ)参照)。そして、断熱パネルPの下面がハゼ継ぎ部18の上面に当接する程度まで下げる。
[3] 金属筒22を引き抜いた後、ボルト体8に抑え体9を螺合させて断熱パネルPを固定する(図6(ホ)参照)。
[4] 断熱パネルの上から防水シート11を敷設し、前記抑え体9に接着することで防水層2を形成する(図6(ヘ)参照)。抑え体9への防水シート11の接着は、例えば、接着材の塗布によって実施する方法や、予め、抑え体9の上面にホットメルト接着層を設けておき、被せた防水シート11の上方から、磁気誘導加熱によって抑え体9を加熱し、その熱で溶けたホットメルト接着層によって接着する等の方法を採用することができる。
The procedure of the roof insulation method will be described. In addition, the said roof heat insulation method can be applied not only to forming the heat insulation roof R by heat insulation repair of the existing roof r, but also to formation of the heat insulation roof R by new construction.
[1] A bolt body 8 including the clamping piece 19, the clamping screw member 20, and the battledore bolt 21 is attached to a predetermined position of the formed seam 18 of the roof r (see FIGS. 6A and 6B). .
[2] In a state in which the metal tube 22 is externally fitted to the bolt portion 21a of the battledore bolt 21 (see FIG. 6C), the heat insulating panel P is disposed on the roof r, and the bolt portion 21a of the bolt body 8 is placed. And the heat insulation panel P is hold | suppressed so that the metal cylinder 22 may stab up from the lower surface of the heat insulation panel P (refer FIG. 6 (D)). And it lowers to such an extent that the lower surface of the heat insulation panel P contacts the upper surface of the goby joint part 18.
[3] After pulling out the metal cylinder 22, the holding body 9 is screwed to the bolt body 8 to fix the heat insulating panel P (see FIG. 6 (e)).
[4] The waterproof sheet 11 is laid from the top of the heat insulating panel and adhered to the holding body 9 to form the waterproof layer 2 (see FIG. 6 (F)). Adhesion of the waterproof sheet 11 to the restraining body 9 is performed, for example, by a method of applying an adhesive or by previously providing a hot melt adhesive layer on the upper surface of the restraining body 9 and from above the waterproof sheet 11 covered. A method of heating the suppressing body 9 by magnetic induction heating and bonding with the hot melt adhesive layer melted by the heat can be adopted.

本実施形態の屋根断熱技術によれば、短いボルト体8を使用して屋根表面への出っ張りを少なくできながら、固定金具の位置ずれの無い状態に目で確認して固定作業を進められ、より精度よく固定金具を屋根面の各稜部に取り付けることができる。そして、ハゼ継ぎの折板屋根に対しても、簡単に屋根断熱化工事を実施できると共に、屋根に対して穴を明けずに固定金具を取り付けることができるから、屋根の強度低下を防止できると共に、屋根本体による防水層と、防水シートによる防水層との二重の防水層によって、より確実な防水性能を発揮することが可能となる。また、断熱パネルの固定作業を効率よく実施することも可能となる。   According to the roof heat insulation technology of the present embodiment, while using the short bolt body 8 to reduce the protrusion to the roof surface, the fixing work can be proceeded by visually confirming that there is no positional deviation of the fixing bracket. Fixing brackets can be attached to each ridge of the roof surface with high accuracy. And it is possible to easily carry out the roof insulation work even for the folded-plate roof of the seam joint, and since the fixing bracket can be attached without making a hole in the roof, the strength of the roof can be prevented from being lowered. The waterproof layer of the roof main body and the waterproof layer of the waterproof sheet can provide more reliable waterproof performance. In addition, the fixing operation of the heat insulation panel can be performed efficiently.
