Description

本発明は家屋や簡易建築物等の外壁や間仕切り、屋根などを構成する建築パネルおよびそれを用いた断熱壁体に関する。 The present invention relates to a building panel constituting an outer wall, a partition, a roof or the like of a house or a simple building, and a heat insulating wall body using the same.

家屋や簡易建築物等の外壁に使用される建築パネルは耐火性に優れていることが必要である。その規制値は、近年では、たとえば外壁の耐火構造においては、建築基準法第77条に基づく指定性能評価機関の防耐火性能試験・評価業務方法書により1時間の加熱を実施し、試験終了時まで試験体の裏面温度上昇が平均140Ｋ以下、最高で180Ｋ以下であることが要求されている。このような断熱性は基本的には、パネル本体を表側外装材と裏側外装材を対向させ、両外装材間に断熱材を充填させる際に断熱材の厚さを増加させることにより対応できる。 Architectural panels used for the outer walls of houses and simple buildings are required to have excellent fire resistance. In recent years, for example, in the fireproof structure of the outer wall, the regulated value has been heated for 1 hour according to the fireproof and fireproof performance test / evaluation work method of the designated performance evaluation organization based on Article 77 of the Building Standards Act, and when the test is completed It is required that the temperature rise of the back surface of the test specimen is an average of 140K or less and a maximum of 180K or less. Such a heat insulating property can be basically dealt with by increasing the thickness of the heat insulating material when the front side exterior material and the back side external material are opposed to each other and the heat insulating material is filled between the both exterior materials.

しかしながら、建築パネルは一般に上下、左右に連結されて使用されるものであり、そのため、家屋や簡易建築物等の全体の断熱性は、単にパネル本体の断熱性のみでなく、パネル接続部の断熱性能、特にパネル接合部からの火炎侵入の防止性能の良否によって大きく左右される。このような問題に対処するため、特許文献１には、表側外皮と裏側外皮とを平行に対向させ、両外皮間に断熱材を充填させてパネルを一体形成し、このパネルの一方端部に凸状の雄実部を突設すると共に他方端部に雌実部を凹設して隣合うパネルの雄実部と雌実部とを実結合し、表側外皮及び裏側外皮にビスのような固着具を貫通させて雌実部の近傍を取付け下地に固定し、パネル表面の雄実部側の端部から隣合うパネルの表面に向けてカバー部を延出させ、このカバー部により前記固着具を覆うという建築用パネルの取付け構造が提案されている。 However, architectural panels are generally used by being connected vertically and horizontally, so the overall thermal insulation of houses, simple buildings, etc. is not only the thermal insulation of the panel body, but also the thermal insulation of panel connections. It depends greatly on the performance, especially the quality of the prevention of flame penetration from the panel joint. In order to cope with such a problem, Patent Document 1 discloses that a front side skin and a back side skin are opposed to each other in parallel, a heat insulating material is filled between both skins, and a panel is integrally formed. A convex male part is protruded and a female part is recessed at the other end to actually connect the male part and the female part of the adjacent panel, and the front side skin and the back side skin are like screws. The fixing tool is penetrated to fix the vicinity of the female real part to the mounting base, and the cover part is extended from the end part on the male real part side of the panel surface toward the surface of the adjacent panel. A construction panel mounting structure that covers the tool has been proposed.

しかしながら、特許文献１に記載の手段におけるパネル接合部からの火炎侵入の防止手段は、パネル厚さ方向の中央部に設けた雄実部と雌実部による嵌合部で行なわれており、一方のパネルの表面材と他方のパネルの表側外皮と裏側外皮（表側外装材と裏側外装材）がそれぞれ外皮ごとには噛み合っていないため、これらの隙間から実結合部に火炎が入る危険がある。また、特許文献１記載の鋼板パネルは火災時に火炎により加熱される側の外皮（鋼板）が熱膨張する一方、火炎の当たらない側の熱膨張が少なく、これにより生ずる熱膨張量の差により加熱される側に外皮（鋼板）が反り返る。この反り返り量は、パネル接合部間の剛性の違いにより差があるので、結局パネル接合部に隙間が生じ、火災時にはその隙間からさらに火炎が侵入することになる。 However, the means for preventing the intrusion of flame from the panel joint in the means described in Patent Document 1 is carried out at the fitting part by the male and female parts provided at the center part in the panel thickness direction, Since the surface material of the panel and the front side skin and the back side skin (the front side exterior material and the back side exterior material) of the other panel are not meshed with each other, there is a risk that a flame enters the actual joint from these gaps. Further, in the steel sheet panel described in Patent Document 1, while the outer shell (steel sheet) heated by the flame is thermally expanded in the event of a fire, the thermal expansion on the side not exposed to the flame is small, and heating is caused by the difference in the amount of thermal expansion caused thereby. The outer skin (steel plate) warps to the side where it is done. Since there is a difference in the amount of warping due to the difference in rigidity between the panel joint portions, a gap is eventually generated in the panel joint portion, and a flame invades further from the gap during a fire.

本発明は、上記建築基準法第77条に基づく指定性能評価機関の防耐火性能試験・評価業務方法書により1時間の加熱を実施したとき、試験終了時まで試験体の裏面温度上昇が平均140Ｋ以下、最高で180Ｋ以下の耐火性能をもち、火災時にパネル接合部からの火炎侵入の原因となるパネル接続部の熱による変形分離を防止し得る建築パネルおよびそれを用いた断熱壁体を提案することを目的とする。 In the present invention, when heating is performed for 1 hour according to the fire resistance test / evaluation work method of the designated performance evaluation organization based on Article 77 of the Building Standards Act, the average temperature increase of the back surface of the specimen is 140K until the end of the test. In the following, we propose a building panel that has a fire resistance of 180K or less at the maximum, and that can prevent deformation separation due to heat of the panel connection part that causes flame intrusion from the panel joint in the event of a fire, and a heat insulating wall body using the same.

図１は、本発明に係る建築パネルの第１実施例の構造を示す断面図である。ここに示すように、本発明の建築パネル1は、本体Mの部分と接続体Jの部分，Kの部分から構成されている。本体Mは、表側外装材11に対向してほぼ平行に配置された裏側外装材21とその間に充填された断熱材31からなっている。この建築パネル1を構成する本体Mの端部に、隣接する建築パネルとの接続体Jの部分，Kの部分がつながるように構成されている。 FIG. 1 is a sectional view showing the structure of a first embodiment of a building panel according to the present invention. As shown here, the building panel 1 of the present invention is composed of a main body M portion, a connecting body J portion, and a K portion.

接続体Jは、本体Mを構成している表側外装材11と裏側外装材21の、図１でいえば上側の両端部に設けられ、接続体Kは、本体Mを構成している表側外装材11と裏側外装材21の、図でいえば下側の両端部に設けられ、これにより図２に示すように、一方の建築パネル1Aの端部に設けられた凸条部12、22が、表側外装材11と裏側外装材21側で、それぞれ他方の建築パネル1Bの端部に設けられた凹溝部13、23の中に入り込み、嵌合連結部（表側外装材側の嵌合連結部C1、裏側外装材側の嵌合連結部C2）が完成され、これにより一方の建築パネル1Aの表側外装材は他方の建築パネル1Bの表側外装材と、また、建築パネル1Aの裏側外装材は他方の建築パネル1Bの裏側外装材と、互いに結合することとなる。具体的には、表側外装材側の嵌合連結部C1は、一方の建築パネル1Aの嵌合連結方向に対して紙面垂直方向に延在する凸条部12と、これに接続される他方の建築パネル1Bの凹溝部18の結合部であり、裏側外装材側の嵌合連結部C2は、一方の建築パネル1Aの嵌合連結方向に対して紙面垂直方向に延在する凸条部22とこれに接続される他方の建築パネル1Bの凹溝部23の結合部である。なお、接続体Jの内側には石膏ボード32、クッション性断熱材33が充填されている。 The connection body J is provided at both upper ends of the front side exterior material 11 and the back side exterior material 21 constituting the main body M in FIG. 1, and the connection body K is the front side exterior material constituting the main body M. The material 11 and the backside exterior material 21 are provided at both lower ends in the figure, and as shown in FIG. 2, the protruding strips 12 and 22 provided at the end of one building panel 1A are provided as shown in FIG. The front side exterior material 11 and the back side exterior material 21 side enter into the recessed groove portions 13 and 23 provided at the end of the other building panel 1B, respectively. C1, the back-side exterior material-side fitting connecting part C2) is completed, so that the front-side exterior material of one building panel 1A is the front-side exterior material of the other building panel 1B, and the back-side exterior material of the building panel 1A is The backside exterior material of the other building panel 1B is bonded to each other. Specifically, the fitting connecting portion C1 on the front side exterior material side includes a protruding strip portion 12 extending in a direction perpendicular to the drawing surface with respect to the fitting connecting direction of one building panel 1A, and the other connected to the protruding strip portion 12. The connecting portion of the recessed groove portion 18 of the building panel 1B, and the fitting connecting portion C2 on the back side exterior material side is a protruding strip portion 22 extending in a direction perpendicular to the drawing surface with respect to the fitting connecting direction of one building panel 1A. This is a joint portion of the groove portion 23 of the other building panel 1B connected to this. The connecting body J is filled with a gypsum board 32 and a cushioning heat insulating material 33.

このような嵌合連結部C1、C2を形成するための凸条部12、22及び凹溝部13、23の形状は、嵌合連結関係が形成できる限り自由に選択できるものであり、本発明の技術的範囲はそれに拘束されるものではないが、その代表的な例を示すと、図１（第１実施例）、図２(第２実施例)のようになる。 The shape of the ridges 12 and 22 and the groove portions 13 and 23 for forming such fitting and coupling portions C1 and C2 can be freely selected as long as the fitting and coupling relationship can be formed. The technical scope is not limited thereto, but a typical example is shown in FIG. 1 (first embodiment) and FIG. 2 (second embodiment).

図１に示す第１実施例について説明する。この例では、凸条部12は、建築パネルの本体Mから延長された外装材11を内側に屈曲させた段部14、この段部14から表側外装材11と平行に立上げた立上り部15、この立上り部15の先端を外側に折り返して形成した係合片16およびこの係合片16の先端を本体M側に折り返した折り返し部121からなっている。そして、立上り部15、係合片16および折り返し部121により凸条122が形成されている。 A first embodiment shown in FIG. 1 will be described. In this example, the ridge portion 12 includes a step portion 14 in which an exterior material 11 extended from the main body M of the building panel is bent inward, and a rising portion 15 that rises in parallel with the front side exterior material 11 from the step portion 14. The engaging piece 16 is formed by folding the leading end of the rising portion 15 outward, and the folded portion 121 is formed by folding the leading end of the engaging piece 16 to the main body M side. The rising portion 15, the engaging piece 16, and the folded portion 121 form a ridge 122.

一方、裏側外装材21に形成される凸条部22は、建築パネルの本体Mから延長された外装材21を内側に屈曲させた段部25、この段部25に続く裏側外装材21と平行に立ち上げた立上り部26、立上り部26の先端を外側に折り返して形成した係合片27およびこの係合片27の先端を本体M側に折り返した折り返し部221からなっている。そして、立上り部26、係合片27および折り返し部221により凸条222が形成されている。 On the other hand, the ridge 22 formed on the backside exterior material 21 is parallel to the backside exterior material 21 following the stepped portion 25 obtained by bending the exterior material 21 extended from the main body M of the building panel inward. , A rising portion 26, an engaging piece 27 formed by folding the tip of the rising portion 26 outward, and a folded portion 221 in which the tip of the engaging piece 27 is folded back to the main body M side. A protruding line 222 is formed by the rising portion 26, the engagement piece 27, and the folded portion 221.

図１に示す例では、凸条122、222は平坦な係合片16、27とその本体側への折り返し部121、221からなっている。しかしながら、凸条の構成はこれに限るものではない。たとえば折り返し部121、221を省略することもできる。 In the example shown in FIG. 1, the ridges 122 and 222 include flat engaging pieces 16 and 27 and folded portions 121 and 221 toward the main body. However, the configuration of the ridges is not limited to this. For example, the folding parts 121 and 221 can be omitted.

表側外装材11に形成される凹溝部13は、建築パネル1の本体Mから表側外装材11が前記凸条部12と反対側に延長され、凸状部22の他端にて、さらに内側に折り返されて形成された二重折返し部18、この二重折返し部18を内方に折り曲げて形成した係合溝19およびその折り返し部131からなっている。この場合において、係合溝19は断熱材31を支持するようになっており、また、二重折返し部18、係合溝19および折り返し部131により凹溝132が形成されている。凹溝部23の構成も上記と同様である。 The concave groove portion 13 formed in the front side exterior material 11 extends from the main body M of the building panel 1 to the opposite side of the convex portion 12 from the main body M, and further on the inner side at the other end of the convex portion 22. It is composed of a double folded portion 18 formed by folding, an engagement groove 19 formed by folding the double folded portion 18 inward, and a folded portion 131 thereof. In this case, the engagement groove 19 is configured to support the heat insulating material 31, and a concave groove 132 is formed by the double folded portion 18, the engagement groove 19, and the folded portion 131. The configuration of the concave groove 23 is the same as described above.

なお、図１に示す例では、上側の接続体Jの内側にはクッション性断熱材33が充填され、下側の接続体Kの内側には石膏ボード32が充填されているが、本発明の建築パネルの構成はこれに限るものではなく、両方にクッション性断熱材のほかの断熱材が充填されるようにしてもよい。 In the example shown in FIG. 1, the upper connecting body J is filled with a cushioning heat insulating material 33, and the lower connecting body K is filled with a gypsum board 32. The construction of the building panel is not limited to this, and both may be filled with another heat insulating material other than the cushioning heat insulating material.

本発明の基本である接続体J，Kの構造は、上記に説明したとおりである。そして、この構造をとることにより、表側外装材および裏側外装材が、それぞれの端部において、隣接する建築パネルの表側外装材および裏側外装材と嵌合連結され、特許文献１記載の発明と異なり、各外装材はそれぞれ直接噛み合うことになる。それにより、火災時に火炎により加熱されてもこれら嵌合連結部で火炎により加熱される側とそうでない側の熱膨張量の差からくる表裏の外装材の反り返り量は低減されるとともにその表裏での差も小さくなり、この部位から火炎が侵入する危険が避けられる。 The structures of the connecting bodies J and K that are the basis of the present invention are as described above. And by taking this structure, the front side exterior material and the back side exterior material are fitted and connected to the front side exterior material and the back side exterior material of the adjacent building panel at the respective end portions, which is different from the invention described in Patent Document 1. Each exterior material is directly meshed with each other. As a result, even when heated by a flame in the event of a fire, the amount of warping of the outer and outer exterior materials resulting from the difference in thermal expansion between the side heated by the flame and the side not heated by these fitting joints is reduced and The difference between the two is also reduced, and the danger of a flame entering from this part is avoided.

このように構成された建築パネル1は、図２に示すように下地材3に取付けられ、壁体とされる。この例では、基礎材2の上に間柱4、下地材3を立設し、この下地材4に対して建築パネル1を建築パネル固定用ビス34（以下単にビス）によって固定し、これを下から上に向けて順次嵌合連結して断熱壁体を構築するようになっている。 The construction panel 1 configured as described above is attached to the base material 3 as shown in FIG. In this example, the stud 4 and the base material 3 are erected on the base material 2, and the building panel 1 is fixed to the base material 4 with building panel fixing screws 34 (hereinafter simply referred to as screws). A heat insulating wall body is constructed by sequentially fitting and connecting from top to bottom.

この取付けの際、ビス34が確実に下地材にねじ込まれるようにするためには、図１に示すように、表側外装材の凸条部12の立上り部15に、ビス34のガイド溝17を設けるとともに、裏側外装材を延長・折り返して形成した段部25を裏側外装材21から立上り部26にかけた斜辺とし、この斜辺を前記建築パネル固定用ビスの誘導斜辺とすることが望ましい。これにより、建築パネル1を下地材3に取付ける際のビス34の打込み位置を一定にすることができ、また打込みの際にビス34が斜行しても、その先端が誘導斜辺によって誘導され、下地3内に正しく固定されることになる（図２参照）。したがって、誘導斜辺には、裏側外装材の延在部24から比較的緩い立上り角（たとえば図１中のθ＝30°）を持たせるとともに、その存在範囲を前記ガイド溝17に対応する位置よりも嵌合するもう一つの建築パネル1Bとの接続部側にとるのがよい。なお、以上の説明では、便宜上、斜辺という言葉で表現しているが、実物では面になっていることはいうまでもない。 In order to ensure that the screw 34 is screwed into the base material at the time of mounting, as shown in FIG. 1, the guide groove 17 of the screw 34 is formed on the rising portion 15 of the convex portion 12 of the front exterior material. It is desirable that the step portion 25 formed by extending and folding the back side exterior material is an oblique side extending from the back side exterior material 21 to the rising portion 26, and this oblique side is the induction oblique side of the building panel fixing screw. Thereby, the driving position of the screw 34 when the building panel 1 is attached to the base material 3 can be made constant, and even if the screw 34 is skewed at the time of driving, the tip is guided by the induction hypotenuse, It will be correctly fixed in the base 3 (see FIG. 2). Therefore, the induction hypotenuse has a relatively loose rising angle (for example, θ = 30 ° in FIG. 1) from the extended portion 24 of the backside exterior material, and its existence range is determined from the position corresponding to the guide groove 17. Also, it is good to take it on the connection side with another building panel 1B to be fitted. In the above description, for the sake of convenience, the term “slope side” is used, but it goes without saying that it is actually a surface.

上記の図１に示す形態の建築パネル1を用いて断熱壁体を構築するためには、表側外装材側の凸条部12の高さH₁をその凹溝部13の深さH₂よりわずかだけ大きく、一方、裏側外装材側の凸条部22の高さH₃をその凹溝部23の深さH₄よりわずかだけ大きくとり、さらに、表側外装材側の凸条部12における係合片16の幅、裏側外装材側の凸条部22における係合片27の幅を、それぞれ表側外装材側の凹溝部13の幅、裏側外装材側の凹溝部23とほぼ同じかそれよりわずかだけ小さくとるのがよい。 In order to construct a heat insulating wall body using the building panel 1 having the form shown in FIG. 1, the height H ₁ of the ridge 12 on the front side exterior material side is slightly smaller than the depth H ₂ of the groove 13. On the other hand, the height H ₃ of the ridge 22 on the back side exterior material side is set to be slightly larger than the depth H ₄ of the groove 23, and the engagement piece on the ridge 12 on the front side exterior material side The width of 16 and the width of the engagement piece 27 in the ridge 22 on the backside exterior material side are approximately the same as or slightly the same as the width of the groove 13 on the front side exterior material side and the groove 23 on the backside exterior material side, respectively. It is good to take small.

具体的には、表側外装材側の凸条部12の高さH₁と凹溝部13の深さH₂、裏側外装材側の凸条部22の高さH_3と凹溝部23の深さH₄の間に以下のような関係をもたせるのがよい。
H₁-H₂=1〜7ｍｍ
H₃-H₄=1〜7ｍｍ Specifically, the height H ₁ of the ridge 12 on the front side exterior material side and the depth H ₂ of the groove 13, the height H _{3 of the} ridge 22 on the back side exterior material side _and the depth of the groove 23 good to impart the following as the relationship between the H _4.
H ₁ -H ₂ = ₁ ~ 7mm
H ₃ -H ₄ = 1 ~ 7mm

これにより、図２に示すように、建築パネル1Aに隣接して建築パネル1Bを建築パネル1Aの凸条部12、22と建築パネル1Bの凹溝部13、23を介して確実に嵌合連結することができる。また、その際、表側凹溝部13の二重折返し部18が表側凸条部12を外部から遮蔽できるようになり、同様に裏側凹溝部21の二重折返し部28が裏側凸条部22を外部から遮蔽できるようになる。 As a result, as shown in FIG. 2, the building panel 1B is securely fitted and connected to the building panel 1A via the ridges 12 and 22 of the building panel 1A and the groove portions 13 and 23 of the building panel 1B adjacent to the building panel 1A. be able to. Also, at that time, the double folded portion 18 of the front groove portion 13 can shield the front convex portion 12 from the outside, and similarly, the double folded portion 28 of the back concave portion 21 externally connects the back convex portion 22 to the outside. Can be shielded from.

図３は、本発明に係る建築パネルの他の実施形態を示す断面図である。この例では、凸条部12の立上り部15、26の先端を断面が山形になるように折り曲げた形状の凸条122、222とし、その先端を係合片16、27としている。この場合、山形の幅を嵌合される凹溝部の幅よりやや大きくすれば、凸条部12が凹溝部13と嵌合するとき、嵌合作業を容易にするとともに、凸条122、222のスプリングバックの作用により両者の嵌合関係がより確実になるという利点がある。 FIG. 3 is a cross-sectional view showing another embodiment of a building panel according to the present invention. In this example, the leading ends of the rising portions 15 and 26 of the projecting ridge portion 12 are convex ridges 122 and 222 that are bent so that the cross section has a mountain shape, and the distal ends thereof are engaging pieces 16 and 27. In this case, if the width of the chevron is made slightly larger than the width of the recessed groove portion to be fitted, when the protruding portion 12 is engaged with the recessed groove portion 13, the fitting operation is facilitated and the protruding portions 122, 222 are There is an advantage that the fitting relationship between the two becomes more reliable by the action of the spring back.

また、図３に示す例では、表側外装材11側に凸条部12を形成する立上り部15に凹溝151を設け、それにより裏側外装材の段部25と共同で石膏ボード32を支持するようにしている。また、表側外装材11の凹溝部13を形成する折り返し部131をさらに内側に折り返して石膏ボード支持片133を形成している。裏側外装材側の石膏ボード支持片233を形成して、共同で石膏ボード32を支持するようにしている。したがって、これら凸条部側の石膏ボード支持部（凹溝151と段部25）と凹溝部側の石膏ボード支持部（石膏ボード支持片133と石膏ボード支持片233）とにより、本体M表側外層材と裏側外装材との間に充填された断熱材31は石膏ボード32とともに長手方向に挟持されることになる。 Further, in the example shown in FIG. 3, a concave groove 151 is provided in the rising portion 15 that forms the ridge portion 12 on the front side exterior material 11 side, thereby supporting the gypsum board 32 in cooperation with the step portion 25 of the back side exterior material. I am doing so. Further, the folded portion 131 that forms the recessed groove portion 13 of the front side exterior material 11 is further folded inward to form the gypsum board support piece 133. The gypsum board support piece 233 on the back side exterior material side is formed so as to support the gypsum board 32 jointly. Therefore, the main body M front side outer layer is formed by the gypsum board support part (concave groove 151 and step 25) on the ridge part side and the gypsum board support part (gypsum board support piece 133 and gypsum board support piece 233) on the concave groove part side. The heat insulating material 31 filled between the material and the backside exterior material is sandwiched with the gypsum board 32 in the longitudinal direction.

さらに、図３に示す例では、表面外装材11が、本体Mと接続体Jとの境界において内側に屈曲されて段部111を形成し、さらに段部111に続けて立上げる形で隠し壁112を形成している。これにより、図４に示すように、隣接する建築パネルと嵌合したとき、隠し壁112がビス34を外部の視線から遮り、組立てたときの美観が維持できるようになる。 Further, in the example shown in FIG. 3, the surface sheathing material 11 is bent inward at the boundary between the main body M and the connection body J to form a stepped portion 111, and further concealed in the form of rising following the stepped portion 111. 112 is formed. As a result, as shown in FIG. 4, the hidden wall 112 shields the screw 34 from the outside line of sight when fitted to an adjacent building panel, and the aesthetic appearance when assembled can be maintained.

図２に示す形態の建築パネル1を用いて断熱壁体を構築し、本発明本来の機能とともに隠し壁としての機能を発揮させるためには、図４からも明らかなように、凹溝部13を形成する二重折返し部18を延長して、建築パネルの結合状態において隠し壁112をカバーするようにするのがよい。 In order to construct a heat insulating wall body using the building panel 1 of the form shown in FIG. 2 and to exhibit the function as a hidden wall as well as the original function of the present invention, as shown in FIG. It is preferable that the double folded portion 18 to be formed is extended so as to cover the hidden wall 112 in the combined state of the building panels.

このような隠し壁112を有する建築パネルの各部寸法を具体的に示すと次のとおりである。
H₅-H₂=1〜7ｍｍ
H₂-H₁≧0ｍｍ
H₃-H₄=1〜7ｍｍ
なお、図３に示す例においても、石膏ボード32に代えてクッション性断熱材ほかの断熱材33が充填されるようにしてもよい。 Specific dimensions of the building panel having such a hidden wall 112 are as follows.
H ₅ -H ₂ = 1 ~ 7mm
H ₂ -H ₁ ≧ 0mm
H ₃ -H ₄ = 1 ~ 7mm
In the example shown in FIG. 3, instead of the gypsum board 32, a heat insulating material 33 other than a cushioning heat insulating material may be filled.

本発明の建築パネルにおいても、断熱機能は対向して配置された外装材間に充填された断熱材により発揮される。この断熱材の選択はパネルの使用個所、要求性能に応じて定めればよいが、およそ次のようにするのがよい。まず、パネル本体部の断熱材31はイソシアネレートやウレタン樹脂、フェノール樹脂等の合成樹脂の発泡体あるいはこれらにガラス繊維等の無機質繊維を混合分散させた発泡体、あるいはロックウール保温板等の板状の無機質繊維体とするのがよい。 Also in the building panel of the present invention, the heat insulating function is exhibited by the heat insulating material filled between the facing materials arranged opposite to each other. The selection of the heat insulating material may be determined according to the place of use of the panel and the required performance. First, the heat insulating material 31 of the panel body is a foam of synthetic resin such as isocyanate, urethane resin or phenol resin, or a foam in which inorganic fibers such as glass fiber are mixed and dispersed therein, or a rock wool heat insulating plate or the like. It is preferable to use a plate-like inorganic fiber body.

これに対し、接続体Ｊ，Kの内側、すなわち、凸条部12、22間および凹溝部13、23間に配置される断熱材32は、たとえば石膏ボードのような比較的硬質のものとして建築パネルを嵌合接続するときの相互の面圧によって変形し難くするのがよい。なお、この断熱材32は上記凸条部12、27側では、少なくとも裏側凸条部22にある段部25によって支持されるようにするのがよく、一方、上記凹溝部13、23側では、折り返し部133，233によって支持されるようにするのが好ましい。また、建築パネルの嵌合連結を円滑に行い、かつ嵌合接続部位における断熱性を確保するために前記硬質の断熱材32の表面側（接続面側）には、たとえばガラスウール、スラグウール、セラミックファイバーブランケットなどのクッション性断熱材33を配するのも好ましい。 On the other hand, the heat insulating material 32 arranged inside the connecting bodies J and K, that is, between the ridges 12 and 22 and between the grooves 13 and 23 is constructed as a relatively hard material such as a plaster board. It is preferable to prevent deformation due to mutual surface pressure when fitting and connecting the panels. It should be noted that the heat insulating material 32 is preferably supported at least on the ridges 12 and 27 side by a step 25 on the back ridge 22 while on the concave grooves 13 and 23 side. It is preferable to be supported by the folded portions 133 and 233. In addition, in order to smoothly fit and connect the building panel and to ensure heat insulation at the fitting connection site, on the surface side (connection surface side) of the hard heat insulating material 32, for example, glass wool, slag wool, It is also preferable to provide a cushioning heat insulating material 33 such as a ceramic fiber blanket.

このように構成された建築パネル1は、図５に示すように下地材3に取付けられ、壁体とされる。この例では基礎材2上に間柱4、下地材3を立設し、この下地材4に対して建築パネル1をビス34によって固定し、これを下から上に向けて順次嵌合連結して断熱壁体を構築するようになっている。 The building panel 1 configured in this manner is attached to the base material 3 as shown in FIG. In this example, the studs 4 and the base material 3 are erected on the base material 2, and the building panel 1 is fixed to the base material 4 with screws 34, which are sequentially fitted and connected from bottom to top. Insulated walls are constructed.

図１に示す構造を有し、表１に記載の材料構成及び寸法を有する建築パネルを製作し、これを上下に連結して壁体として組立て、建築基準法第77条に基づく指定性能評価機関の防耐火性能試験・評価業務方法書により加熱を実施した。測温は、図１に示すように建築パネル裏面21の高さ方向中央部(A)及び建築パネル裏面の二重折返し部28の下端部近傍(B)にそれぞれ建築パネル紙面垂直方向8ヶ所に熱電対を取付けて行なった。 A construction panel having the structure shown in FIG. 1 and having the material composition and dimensions shown in Table 1 is manufactured and assembled as a wall by connecting it up and down. Heating was carried out according to the fire prevention and performance test / evaluation work method. As shown in FIG. 1, the temperature measurement is performed at eight positions in the vertical direction of the building panel paper surface in the center (A) in the height direction of the back 21 of the building panel and in the vicinity of the lower end (B) of the double folded portion 28 on the back of the building panel. This was done with a thermocouple attached.

その結果得られた耐火性能試験・評価結果は図６に示す試験時間に対する試験体の裏面上昇温度値の関係を示すグラフのとおりであった。図６に示すとおり、本発明による建築パネルは1時間の加熱を実施したとき、試験終了時まで試験体の裏面温度上昇が平均140Ｋ以下、最高で180Ｋ以下の耐火性能をもつことが確認できた。また、試験後、断熱壁体を解体して嵌合連結部の変形の有無を調査したところ、火災時にパネルの嵌合連結部からの火炎侵入の原因となる程度の大きな変形は認められず、火災時にもパネルの嵌合連結部での分離が十分防止し得る建築パネルであることが確認できた。 As a result, the fire resistance performance test / evaluation results obtained were as shown in the graph showing the relationship of the back surface rising temperature value of the specimen with respect to the test time shown in FIG. As shown in FIG. 6, when the building panel according to the present invention was heated for 1 hour, it was confirmed that the back surface temperature rise of the test specimen had an average of 140 K or less and a maximum of 180 K or less until the end of the test. . In addition, after the test, when the thermal insulation wall was disassembled and the presence or absence of deformation of the fitting connection portion was investigated, a large deformation that would cause flame intrusion from the fitting connection portion of the panel at the time of a fire was not observed, It was confirmed that the building panel can be sufficiently prevented from separating at the fitting connection part of the panel even in the event of a fire.

図３に示す構造を有し、実施例１と同様の材料構成を有する建築パネルを表２に示すパネル寸法により製作し、これを上下に連結して壁体として組立て、実施例１と同様の試験を行った。その結果得られた耐火性能試験・評価結果は図６に示す試験時間に対する試験体の裏面上昇温度値の関係を示すグラフのとおりであった。この場合においても、実施例１の場合と同様の効果を確認できた。 A building panel having the structure shown in FIG. 3 and having the same material structure as that of the first embodiment is manufactured according to the panel dimensions shown in Table 2, and is assembled vertically as a wall body, similar to that of the first embodiment. A test was conducted. As a result, the fire resistance performance test / evaluation results obtained were as shown in the graph showing the relationship of the back surface rising temperature value of the specimen with respect to the test time shown in FIG. In this case, the same effect as in Example 1 was confirmed.
