しかしながら、この外壁パネルでは、内部結露を生じやすい、ヒートブリッジによって室温が変動しやすい、パネル間の目地を湿式でコーキングしなければならないなどの不利な面を有していた。   However, this outer wall panel has disadvantages such as that internal condensation tends to occur, the room temperature tends to fluctuate due to a heat bridge, and the joints between the panels must be wet-coked.

本発明は、このような背景において、内部結露を生じにくく、ヒートブリッジを少なくして室温変動を小さく抑えることができ、パネル間を乾式目地材でシールすることができ、更に多くの利点を有する断熱外壁パネル及び断熱外壁構造を提供することを課題とする。   In such a background, the present invention is less likely to cause internal dew condensation, can reduce heat bridges to suppress room temperature fluctuation, can be sealed between panels with a dry joint material, and has many advantages. It is an object to provide a heat insulating outer wall panel and a heat insulating outer wall structure.

上記の課題は、パネルフレームの屋外側に板状の外断熱材が重ねられ、その外側に外壁材が備えられていることを特徴とする断熱外壁パネルによって解決される。   Said subject is solved by the heat insulation outer wall panel characterized by the plate-shaped outer heat insulating material being piled up on the outdoor side of a panel frame, and the outer wall material being provided in the outer side.

この断熱外壁パネルは、パネルフレームの屋外側に板状の外断熱材が重ねられた、いわゆる外断熱外壁パネルに構成されているものであるから、内部結露を生じにくい。しかも、外壁パネル間を外断熱材で断熱することもでき、ヒートブリッジを防いで室温変動を小さく抑えることができる。また、隣り合う外壁パネル間の目地の深さ寸法が外断熱材によって大きく確保され、乾式目地材で外壁パネル間をシールすることもできて、目地の防水施工の作業性向上を図ることが可能となる。   This heat insulating outer wall panel is configured as a so-called outer heat insulating outer wall panel in which a plate-like outer heat insulating material is stacked on the outdoor side of the panel frame, and therefore, internal condensation is unlikely to occur. In addition, it is possible to insulate between the outer wall panels with an outer heat insulating material, thereby preventing a heat bridge and suppressing a change in room temperature to be small. In addition, the depth of the joint between the adjacent outer wall panels is greatly secured by the outer heat insulating material, and the outer wall panels can be sealed with the dry joint material, so that the workability of the waterproof construction of the joint can be improved. It becomes.

のみならず、外断熱材を外壁パネルのパネルフレームに重ねるようにして外壁パネルに備えさせているから、外断熱材をパネルフレームで補強することができ、そのため、外断熱材から専用の補強枠材を排除することができて、外壁構造を簡素化することができる。即ち、外壁パネルと外断熱パネルとを別々のパネルに構成する場合には、外断熱材には、これを補強する専用枠材が必要であるが、外壁パネルに予め外断熱材を組み込むパネル構成とすることで、外断熱材に専用の枠材を排除することができ、外壁構造を簡素な構造にすることができる。   Not only that, the outer wall panel is provided with the outer heat insulating material so as to overlap the panel frame of the outer wall panel. Therefore, the outer heat insulating material can be reinforced with the panel frame. The material can be eliminated, and the outer wall structure can be simplified. In other words, when the outer wall panel and the outer heat insulating panel are configured as separate panels, the outer heat insulating material requires a special frame material to reinforce this, but the panel structure in which the outer heat insulating material is pre-installed in the outer wall panel By doing so, a frame material dedicated to the outer heat insulating material can be eliminated, and the outer wall structure can be made a simple structure.

外断熱材としては、例えば、ポリプロピレンフォーム、ポリスチレンフォーム、発泡ポリウレタン等の発泡樹脂、あるいは、これらにフェノール、イソシアヌレートなどの有機材料、ハロゲン等をブレンドして耐火性能を高めたもの、あるいは、耐火性能に優れた無機系の発泡材などが用いられる。また、外断熱材として、ポリプロピレンフォームなどの止水性を有するものを用いることにより、外断熱材それ自体でパネル内への雨水等の侵入を防ぐことが可能となる。   As an external heat insulating material, for example, a foamed resin such as polypropylene foam, polystyrene foam, and foamed polyurethane, or an organic material such as phenol or isocyanurate, a halogen blended with these, or a fireproof performance is improved. An inorganic foam material having excellent performance is used. In addition, by using a water-resistant material such as polypropylene foam as the outer heat insulating material, it is possible to prevent rainwater and the like from entering the panel with the outer heat insulating material itself.

パネルフレームに囲まれた内部に内断熱材が備えられている場合は、この内断熱材と外断熱材とで断熱性能を高めることができるのみならず、内断熱材を内部結露で濡らしてしまうのを防ぐことができる。しかも、内断熱材の使用により、外断熱材の厚さ寸法を小さくすることができ、建物外への外断熱材の突出を小さく抑えることができる。加えて、室内の冷暖房の立ち上がりを速くすることができる。内断熱材としては、グラスウール、ロックウール等の繊維系断熱材が用いられてもよいし、発泡ウレタンなどの発泡樹脂が用いられてもよい。   When the inner heat insulating material is provided inside the panel frame, the inner heat insulating material and the outer heat insulating material can not only improve the heat insulating performance but also wet the inner heat insulating material with internal condensation. Can be prevented. Moreover, by using the inner heat insulating material, the thickness dimension of the outer heat insulating material can be reduced, and the protrusion of the outer heat insulating material to the outside of the building can be suppressed to be small. In addition, the start-up of indoor air conditioning can be accelerated. As the inner heat insulating material, a fiber heat insulating material such as glass wool or rock wool may be used, or a foamed resin such as urethane foam may be used.

外断熱材の外面部に通気層を形成する凹所が形成されている場合は、外断熱材と外壁材との間に通気層を形成することができる。のみならず、外断熱材の内面側はパネルフレームで支えられて補強されているから、外断熱材の外面側に補強枠を備えさせる必要がなく、そのため、外断熱材の外面側に直接通気用の凹所を形成することができ、外断熱材と外壁材との間に通気層を有する外壁パネルを簡素な構造で実現することができる。しかも、予めこの凹所の形成された外断熱材を用いて外壁パネルを製作することにより、外壁パネルの製作を容易に行うことができる。   In the case where a recess for forming a ventilation layer is formed in the outer surface portion of the outer heat insulating material, it is possible to form a gas permeable layer between the outer heat insulating material and the outer wall material. Not only that, the inner surface side of the outer heat insulating material is supported and reinforced by the panel frame, so there is no need to provide a reinforcing frame on the outer surface side of the outer heat insulating material. Therefore, an outer wall panel having a ventilation layer between the outer heat insulating material and the outer wall material can be realized with a simple structure. Moreover, the outer wall panel can be easily manufactured by manufacturing the outer wall panel using the outer heat insulating material in which the recess is formed in advance.

外断熱材が発泡樹脂からなり、その内部に耐熱性を有するスペーサーが埋め込まれており、外壁材が、このスペーサーを通じてパネルフレームに連結されている場合は、火災などで外断熱材が焼失しても、外壁材の脱落を防ぐことができる。   If the outer heat insulating material is made of foamed resin, and a heat-resistant spacer is embedded inside, and the outer wall material is connected to the panel frame through this spacer, the outer heat insulating material will be burned down due to fire, etc. However, it is possible to prevent the outer wall material from falling off.

建物躯体の柱の両側に上記の断熱外壁パネルがパネルフレームで柱を両側から挟むように取り付けられ、各外壁パネルの外断熱材は柱の前面側に張り出して所定の間隔をおいて対向し、この対向面間に乾式目地材が嵌め込まれている断熱外壁構造の場合は、このように、乾式目地材で目地をシールすることができ、目地の施工を能率良く行うことができる。   The above-mentioned heat insulation outer wall panels are attached to both sides of the pillars of the building frame so that the pillars are sandwiched from both sides by the panel frame, and the outer heat insulating materials of each outer wall panel protrude to the front side of the pillars and face each other with a predetermined interval, In the case of the heat insulating outer wall structure in which the dry joint material is fitted between the facing surfaces, the joint can be sealed with the dry joint material in this way, and the joint can be efficiently constructed.

本発明は、以上のとおりのものであるから、内部結露を生じにくく、ヒートブリッジを少なくして室温変動を小さく抑えることができ、パネル間を乾式目地材でシールすることができるのみならず、その他、種々有利な効果を発揮することができる。   Since the present invention is as described above, internal condensation is unlikely to occur, the heat bridge can be reduced to reduce room temperature fluctuation, and not only can the panel be sealed with a dry joint material, In addition, various advantageous effects can be exhibited.

実施形態の外壁パネルを示すもので、図（イ）は断面平面図、図（ロ）は図（イ）のＩ−Ｉ線断面図である。The external wall panel of embodiment is shown, A figure (A) is a cross-sectional top view, A figure (B) is II sectional view taken on the line of FIG. 同外壁パネルの分解斜視図である。It is a disassembled perspective view of the same outer wall panel. 外壁パネルを建物に取り付ける前の状態を示す断面平面図である。It is a cross-sectional top view which shows the state before attaching an outer wall panel to a building. 図（イ）は外壁パネルを取り付けた状態を示す断面平面図、図（ロ）は柱部分を拡大した断面平面図である。FIG. 1A is a sectional plan view showing a state where an outer wall panel is attached, and FIG.

次に、本発明の実施形態を図面に基づいて説明する。   Next, embodiments of the present invention will be described with reference to the drawings.

図１及び図２に示す実施形態の断熱外壁パネル１において、２はパネルフレーム、３は外断熱材、４は外壁材としての外壁面材、５は内断熱材である。   In the heat insulating outer wall panel 1 of the embodiment shown in FIGS. 1 and 2, 2 is a panel frame, 3 is an outer heat insulating material, 4 is an outer wall surface material as an outer wall material, and 5 is an inner heat insulating material.

パネルフレーム２は、上下左右の鋼製溝形材を開口側を内向きにして方形環状に組んだもので、このパネルフレーム２に囲まれた内部には内断熱材５が備えられている。内断熱材５は、例えばグラスウールなどからなる。   The panel frame 2 is formed by assembling upper, lower, left and right steel channel shapes in a square ring shape with the opening side facing inward, and an inner heat insulating material 5 is provided inside the panel frame 2. The inner heat insulating material 5 is made of, for example, glass wool.

そして、このパネルフレーム２の屋外側に、板状の外断熱材３が重ねられて取り付けられている。外断熱材３は、例えば、断熱性、剛性、止水・防水性のいずれにも優れた、例えばポリプロピレンフォームなどの発泡樹脂成形品からなる。このように、外断熱材３を外壁パネル１のパネルフレーム２に重ねるようにして取り付ける構成とすることによって、外断熱材３をこのパネルフレーム２で補強することができ、外断熱材３から専用の補強枠材を排除して、外壁構造を図３に示すように簡素なものにすることができる。   And the plate-shaped outer heat insulating material 3 is piled up and attached to the outdoor side of this panel frame 2. FIG. The outer heat insulating material 3 is made of, for example, a foamed resin molded product, such as polypropylene foam, which is excellent in all of heat insulating properties, rigidity, water stop / waterproof properties. Thus, by setting it as the structure which attaches the outer heat insulating material 3 so that it may overlap with the panel frame 2 of the outer wall panel 1, the outer heat insulating material 3 can be reinforced with this panel frame 2, and it is exclusive from the outer heat insulating material 3. Thus, the outer wall structure can be simplified as shown in FIG.

この外断熱材３は、図１（イ）に示すように、その左右両側部がパネルフレーム２よりも側方に突出するように備えられており、この突出部分が、図３及び図４に示すように、建物躯体の柱６の前面側に張り出すようになされている。
また、外断熱材３の側面には、例えば図示面に示すように上下方向に延びる凹条７，７などによる凹凸が形成されている。この凹凸は、乾式目地材を係合させるものであり、外断熱材３の側面部に直接に形成されている。 As shown in FIG. 1 (a), the outer heat insulating material 3 is provided such that its left and right side portions protrude laterally from the panel frame 2, and this protruding portion is shown in FIG. 3 and FIG. As shown, it projects over the front side of the pillar 6 of the building frame.
Further, on the side surface of the outer heat insulating material 3, for example, as shown in the drawing surface, unevenness is formed by concave grooves 7, 7 extending in the vertical direction. The unevenness is for engaging the dry joint material and is formed directly on the side surface portion of the outer heat insulating material 3.

更に、この外断熱材３の外面部には、縦向きの延びる凹所８が横方向に複数列設されており、外壁面材４を外断熱材３の外面部に沿わせるように取り付けた状態で、外断熱材３と外壁面材４との間に通気層９…が形成されるようになされている。この通気部形成用の凹所８は、外断熱材３に直接形成されており、例えば外断熱材３を成形するときに同時成形で形成されたものであってよい。   Further, a plurality of vertically extending recesses 8 are arranged in the lateral direction on the outer surface portion of the outer heat insulating material 3, and the outer wall surface material 4 is attached so as to be along the outer surface portion of the outer heat insulating material 3. In the state, a ventilation layer 9 is formed between the outer heat insulating material 3 and the outer wall surface material 4. The recess 8 for forming the ventilation portion is formed directly in the outer heat insulating material 3, and may be formed by, for example, simultaneous molding when the outer heat insulating material 3 is formed.

そして、この外断熱材３の外面側に外壁面材４が備えられている。この外壁面材４は、次のようにして取り付けられている。即ち、外断熱材３には、金属や樹脂などによる筒状あるいはリング状の耐熱スペーサー１０が埋込み状態に備えられていて、ビスなどの取付け金具１１が、このスペーサー１０に通され、このスペーサー１０を介してパネルフレーム２に取り付けられており、外壁面材４とパネルフレーム２とは、外断熱材３がなくとも、このスペーサー１０を介して取付け金具１１によって適正な取付け状態を維持しうるようになされている。これにより、火災によって外断熱材３が万一焼失しても、外壁面材４が建物から脱落してしまうのを防ぐことができる。   An outer wall surface material 4 is provided on the outer surface side of the outer heat insulating material 3. The outer wall surface material 4 is attached as follows. In other words, a cylindrical or ring-shaped heat-resistant spacer 10 made of metal, resin, or the like is provided in the outer heat insulating material 3 in an embedded state, and a mounting bracket 11 such as a screw is passed through the spacer 10. The outer wall surface material 4 and the panel frame 2 can be maintained in the proper mounting state by the mounting bracket 11 via the spacer 10 even without the outer heat insulating material 3. Has been made. Thereby, even if the outer heat insulating material 3 should be burned down by a fire, it can prevent that the outer wall surface material 4 falls off from a building.

上記の外壁パネル１は、図３及び図４に示すように、建物躯体の柱６の両側に、パネルフレーム２，２で柱６を両側から挟むように取り付けられる。これにより、図４（ロ）に示すように、各外壁パネル１，１の外断熱材３，３は、柱６の前面側に張り出し、所定の目地幅間隔をおいて対向する。外断熱材３，３が柱６の前面側に張り出すことで、ヒートブリッジが抑えられる。そして、この対向面間に乾式目地材１２が嵌め込まれ、外壁パネル１，１間がシールされている。乾式目地材１２には、目地幅の変動に追従する弾力性あるゴム状のものを用いるとよい。このように、外断熱材３を組み込んだ外壁パネル１とすることにより、目地１３の深さ寸法をある程度大きくすることができ、目地１３のシーリングに乾式目地材１２を使用することができるようになり、目地の施工を能率良く行うことができるようになる。特に、外断熱材３の側面に形成した凹条７などによる凹凸との係合作用で乾式目地材１２をしっかりと目地１３内に保持することができる。この凹条７などによる凹凸は発泡樹脂製外断熱材３の側面に形成すればよいから、その形成も容易である。   As shown in FIGS. 3 and 4, the outer wall panel 1 is attached to both sides of the pillar 6 of the building frame so that the pillar 6 is sandwiched from both sides by the panel frames 2 and 2. As a result, as shown in FIG. 4B, the outer heat insulating materials 3 and 3 of the respective outer wall panels 1 and 1 project to the front side of the column 6 and face each other with a predetermined joint width interval. Heat bridge is suppressed by the outer heat insulating materials 3 and 3 projecting to the front side of the column 6. Then, a dry joint material 12 is fitted between the opposing surfaces, and the space between the outer wall panels 1 and 1 is sealed. As the dry joint material 12, it is preferable to use an elastic rubber material that follows the joint width variation. Thus, by setting it as the outer wall panel 1 incorporating the outer heat insulating material 3, the depth dimension of the joint 13 can be enlarged to some extent, and the dry joint material 12 can be used for sealing the joint 13. Thus, the joint construction can be performed efficiently. In particular, the dry joint material 12 can be firmly held in the joint 13 by the engaging action of the concave and convex portions 7 and the like formed on the side surface of the outer heat insulating material 3. Since the concave and convex portions due to the concave stripes 7 and the like may be formed on the side surface of the foamed resin outer heat insulating material 3, it can be easily formed.

図５及び図６に示す実施形態の外壁パネル１は、タイル貼り外壁パネルからなり、サイディングにタイルを接着剤やビスで取り付けたものを外壁材４とし、複数のこの外壁材４…が外断熱材３の外面部にサイディング固定金物１５…によって外断熱材３に対して取り付けられている。この場合、外断熱材３として、ポリプロピレンフォームなどのような、下地としての剛性が高く、しかも、止水性に優れる発泡樹脂を用いることにより、これら外壁材４…を外断熱材３にしっかりと保持させることができると共に、外断熱材３によって雨水等の侵入を防ぐことができる。外断熱材３の外面には、サイディング固定金物１５を取り付ける凹所１６を形成しておくとよい。サイディング固定金物１５をこの凹所１６内に突出させるようにして取り付けることで、外壁材４…と外断熱材３とを近接状態にすることができる。なお、図示しないが、サイディング固定金物１５用の凹所１６より幾分深い通気層形成用の凹所９…を外断熱材３の外面に縦向き延ばして形成しておくことにより、外壁材４の背面側に侵入した雨水等をスムーズに流下させることができる。   The outer wall panel 1 of the embodiment shown in FIGS. 5 and 6 is composed of a tiled outer wall panel, and a tile is attached to a siding with an adhesive or a screw as an outer wall material 4, and a plurality of these outer wall materials 4. The outer surface of the material 3 is attached to the outer heat insulating material 3 by siding fixing hardware 15. In this case, the outer heat insulating material 3 is firmly held by the outer heat insulating material 3 by using a foamed resin having high rigidity as a base, such as polypropylene foam, and having excellent water-stopping properties. In addition, the outer heat insulating material 3 can prevent intrusion of rainwater and the like. A recess 16 for attaching the siding fixture 15 may be formed on the outer surface of the outer heat insulating material 3. By attaching the siding fixed hardware 15 so as to protrude into the recess 16, the outer wall material 4 and the outer heat insulating material 3 can be brought into a close state. Although not shown in the drawings, the outer wall material 4 is formed by vertically extending the recesses 9 for forming the air-permeable layer somewhat deeper than the recesses 16 for the siding fixing hardware 15 on the outer surface of the outer heat insulating material 3. Rainwater that has entered the back side of the water can flow smoothly.

以上に、本発明の実施形態を示したが、本発明はこれに限られるものではなく、発明思想を逸脱しない範囲で、各種の変更が可能である。例えば、板状の外断熱材は、一枚物であってもよいし、上下方向及び／又は左右方向に断熱材を複数組んで構成されたものであってもよい。   Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made without departing from the spirit of the invention. For example, the plate-like outer heat insulating material may be a single piece, or may be configured by combining a plurality of heat insulating materials in the vertical direction and / or the horizontal direction.
