従来例1は、非特許文献1及び非特許文献2に開示されたものであり、図10に示す如く、内面に条溝を備え、適所にあと施工アンカー用の孔を配設したセメント板に断熱層を一体化層着した密着層型の外断熱複合パネルの断熱層を、接着剤でコンクリート躯体に接着し、アンカーをセメント板からコンクリート躯体に打ち付けて張着する。
There are a conventional example 1 shown in FIG. 10 and a conventional example 2 shown in FIG. 11 as a technique for sticking an adhesive layer type heat insulating composite panel to a concrete frame to form an external heat insulating building.
Conventional Example 1 is disclosed in Non-Patent Document 1 and Non-Patent Document 2, and as shown in FIG. 10, a cement plate provided with a groove on the inner surface and provided with holes for post-construction anchors at appropriate positions. The heat-insulating layer of the adhesion layer type outer heat-insulating composite panel with the heat-insulating layer integrally attached is adhered to the concrete case with an adhesive, and the anchor is driven from the cement plate to the concrete case to be stuck.

そして、コンクリート躯体に打込んだ、あと施工アンカーボルトに締着した重量受けアングルで断熱複合パネルの外壁下端を支承すると共に、外壁上部では、コンクリート躯体(パラペット)上端面に笠木取付下地をあと施工アンカーで固定し、笠木を取付下地に係止してパネル上端前面と笠木間、及びコンクリート躯体上面と笠木後端との間をシーリングするものであり、コンクリート建築物を外断熱に改修する技術である。   Then, the lower end of the outer wall of the heat-insulated composite panel is supported by the weight receiving angle that is driven into the concrete frame and fastened to the anchor bolts. At the upper part of the outer wall, the headboard is attached to the upper end of the concrete frame (parapet). This is a technology to fix the concrete building to external insulation by fixing it with an anchor and locking the headboard to the mounting base and sealing between the front end of the panel and the headboard, and between the upper surface of the concrete frame and the rear end of the headboard. is there.

また、従来例2は、非特許文献3に開示されたものであり、図11に示す如く、GFPC系外装材(厚さ13mmの両面ガラス繊維混入火山礫サンドアッシュフェノール樹脂板)と、断熱材とを接着一体化した密着層型の断熱複合パネル(岩倉化学工業(株)の商品名:オーマルYB−R)を外装材とし、外装材には、あと施工アンカー用の孔を適所に配設すると共に、断熱層表面にはだんご状の接着剤を適宜間隔に配設し、だんご状接着剤でパネルの断熱層をコンクリート躯体表面に貼着し、あと施工アンカーを外装材表面からコンクリート躯体へ打ち込んで張着するものである。   Conventional Example 2 is disclosed in Non-Patent Document 3, and as shown in FIG. 11, a GFPC-based exterior material (13 mm thick double-sided glass fiber mixed volcanic gravel sand ash phenol resin plate), and a heat insulating material Adhesive layer-type heat-insulating composite panel (trade name: Omar YB-R from Iwakura Chemical Industry Co., Ltd.) is used as the exterior material. At the same time, the surface of the heat insulation layer is provided with a dango-like adhesive at appropriate intervals, and the heat insulation layer of the panel is adhered to the surface of the concrete body with the dango-like adhesive, and the post-installed anchor is then attached from the exterior material surface to the concrete body.

既存建物の改修に於いて、従来例1や従来例2の乾式被覆改修外断熱構工法は、既存建物の外壁に取付金物によってパネルを乾式に取付けるもので、既存外壁の仕上材に剥離や剥落の恐れのあるコンクリート建築物や、汚れやデザインの陳腐化したコンクリート建築物の改修に多用されており、新築の外断熱コンクリート建築物と同様に、結露が防止出来て健康的な建物に改修出来、省エネルギー、且つ耐久性のあるコンクリート建物に改修出来る。   In the renovation of existing buildings, the dry insulation renovation external insulation construction method of Conventional Example 1 and Conventional Example 2 is a method of attaching panels to the outer wall of the existing building with mounting hardware, and peeling or peeling off the finishing material of the existing outer wall. It is often used for renovation of concrete buildings that are likely to be damaged, or that have become dirty or obsolete, and can be renovated to a healthy building that can prevent condensation, just like a newly-constructed external insulation concrete building It can be renovated into a concrete building with energy saving and durability.

しかし、日本建築学会編、「建築工事標準仕様書、同解説(JASS5)鉄筋コンクリート工事」1997年版では、外壁面の不陸は、タイルの圧着張りでは、3mにつき10mm以下、モルタル塗では1mにつき10mm以下、打放しコンクリートでは、3mにつき7mm以下となっているが、建築後15〜20年経過したコンクリート建築物にあっては、建築時の型枠精度等の問題から1mにつき10mm位の不陸の存在は普通である。   However, in the 1997 edition of the Architectural Institute of Japan, “Building Construction Standard Specification, Commentary (JASS 5) Reinforced Concrete Construction” 1997 edition, the unevenness of the outer wall surface is 10 mm or less for 3 m for tiles and 10 mm for 1 m for mortar coating. In the following, the concrete is less than 7mm per 3m, but for concrete buildings 15 to 20 years after construction, due to problems such as form accuracy at the time of construction, it is about 10mm per 1m. Existence is normal.

従来例1(図10)の乾式被覆改修構工法にあっては、既存建物の外壁のコンクリート躯体表面に断熱複合パネルを面接着するため、コンクリート躯体外面に不陸(面の不平坦)があれば、断熱複合パネルの前後方向調整が不可能であるため、断熱複合パネルの外壁面もコンクリート躯体の不陸に追従して不陸となる。
従って、外壁面をなるべく面一にするために、断熱複合パネルの張着に先立ってコンクリート躯体外面の突出面を斫る面一化作業が必要であり、斫り作業は作業性が悪く、しかも、コンクリート躯体表面の面一化は困難である。
In the dry coating repair method of Conventional Example 1 (Fig. 10), the thermal insulation composite panel is bonded to the surface of the concrete frame on the outer wall of the existing building, so there is unevenness on the outer surface of the concrete frame. For example, since it is impossible to adjust the heat-insulating composite panel in the front-rear direction, the outer wall surface of the heat-insulating composite panel also becomes uneven following the unevenness of the concrete frame.
Therefore, in order to make the outer wall surface as flat as possible, it is necessary to perform a leveling operation to crush the protruding surface of the concrete frame prior to the tensioning of the heat insulating composite panel. It is difficult to make the surface of the concrete body uniform.

また、該断熱複合パネルは、当初、該セメント板がコンクリート一体化用型枠として開発され、一体化コンクリートとの付着性向上のために条溝を付設したものであったが、コンクリート建築物に対する外断熱施工への関心の高まりと共に、該セメント板に断熱材を層着一体化して断熱複合パネル(商品名:アキレスKDパネル)とされたものであり、該条溝は、該パネルにあってはセメント板の軽量化の意義しかないものである。   In addition, the heat insulating composite panel was originally developed as a concrete integrated formwork, and was provided with a groove to improve adhesion to the integrated concrete. Along with the increasing interest in external heat insulation construction, a thermal insulation composite panel (trade name: Achilles KD panel) is formed by layering a heat insulating material on the cement board, and the groove is provided in the panel. Is only meaningful to reduce the weight of the cement board.

そして、従来例1の断熱複合パネルによる外壁は、重量受けアングルがパネル下端面を面当接で支承していること、及び笠木とパネル上端前面との間、笠木とパラペットとの間にシーリングを施していることからも明らかな如く、密着層型のパネル内に通気性が存在しない。
従って、該パネルの外壁は、セメント板が日射による高温化に伴うヒートストレスにより劣下し、且つ、断熱層とセメント板間には、密着層型外断熱複合パネル特有の界面結露の問題を有する。
And the outer wall by the heat insulation composite panel of the prior art example 1 is that the weight receiving angle supports the lower end surface of the panel by surface contact, and seals between the headboard and the front end of the panel, and between the headboard and the parapet. As is clear from the above, there is no air permeability in the adhesion layer type panel.
Therefore, the outer wall of the panel is inferior to the heat stress caused by the high temperature caused by solar radiation, and between the heat insulating layer and the cement plate, there is a problem of interfacial dew condensation peculiar to the adhesion layer type outer heat insulating composite panel. .

また、従来例2(図11)の乾式被覆改修構工法にあっても、断熱複合パネルのコンクリート躯体表面への張着は、接着剤のだんごを点在配置してパネルを押圧接着するため、だんご状接着剤の押圧変形がコンクリート躯体表面の不陸に若干対応出来るものの、不陸調整寸法が小であるため、やはり、パネルの張着に先立って、コンクリート躯体表面の突出面を斫る作業も必要であり、斫り作業を伴う断熱複合パネルの張着の作業性が悪く、しかも外壁面の面一化張着は困難である。
そして、該断熱複合パネルは、GFPC系外装材と断熱層との密着層型パネルであるが、該パネル自体は通気層が存在せず、断熱層と外装材間には、密着層型の外断熱複合パネル特有の界面結露を生ずるものである。
In addition, even in the dry coating repair construction method of the conventional example 2 (FIG. 11), the thermal insulation composite panel is stuck to the surface of the concrete frame because the adhesive balls are scattered and pressed to adhere to the panel. Although the pressure deformation of the dango-like adhesive can cope with the unevenness of the concrete body surface slightly, the unevenness adjustment dimension is small, so the work of rubbing the protruding surface of the concrete body surface before the panel is stuck This is also necessary, and the workability of tensioning of the heat-insulating composite panel accompanying the turning work is poor, and it is difficult to achieve uniform tensioning of the outer wall surface.
The heat insulating composite panel is an adhesion layer type panel of a GFPC-type exterior material and a heat insulation layer, but the panel itself does not have an air-permeable layer, and there is no adhesion layer type outer space between the heat insulation layer and the exterior material. Interfacial dew condensation peculiar to a heat insulating composite panel is generated.

本発明は、密着層型の断熱複合パネルでありながら、パネル内通気が可能な外壁となり、しかも、断熱複合パネルのコンクリート躯体表面への張着は、コンクリート躯体表面の不陸に関係なく外壁表面を面一に、且つ、作業性良く施工出来る新規な外壁の上部構造を提供し、しかも、密着層型断熱複合パネルでありながら、外壁下端の腰水切から上下連設パネル内を貫通して上端の笠木への通気も可能となる外壁の上部構造を提供するものであり、上述の如き、従来例1、従来例2の問題点を一挙に解決するものである。   The present invention is an adhesion layer type heat insulation composite panel, and becomes an outer wall capable of venting the panel, and the heat insulation composite panel is attached to the surface of the concrete frame regardless of the unevenness of the surface of the concrete frame. In addition to providing a new superstructure of the outer wall that can be constructed with good workability and good workability, it is an adhesive layer type heat insulating composite panel that penetrates the upper and lower panels from the lower drainage panel at the lower end of the outer wall. The upper structure of the outer wall that allows ventilation to the headboard is provided, and the problems of the conventional examples 1 and 2 are solved at a time as described above.

本発明は、例えば図1(A),(B)に示す如く、内面に条溝aを上下方向に並設したセメント板Paと断熱層Pbとを層着した密着層型の断熱複合パネルPと、一次ファスナー7と、二次ファスナー10と、笠木3とを含み、一次ファスナー7は、コンクリート躯体Cwの前面Scに固定し、二次ファスナー10は、断熱複合パネルP上端面のセメント板Paの条溝a内への二次ファスナー側の突出片12bの係合により係止すると共に、一次ファスナー7に前後左右調整して止着し、笠木3は、前部を該パネルP上端部に止着したブラケット15を介して支持し、後部を後方に延出した底板3Dを介してコンクリート躯体上端面Fcに止着し、該パネル断熱層Pbとコンクリート躯体前面Scとの界面隙間asの空気流通を阻止すると共に、該パネル内の条溝a群から笠木3を介した外方への空気流通を保証したものである。   In the present invention, for example, as shown in FIGS. 1 (A) and 1 (B), an adhesion layer type heat insulating composite panel P in which a cement plate Pa and a heat insulating layer Pb, in which the grooves a are arranged in the vertical direction on the inner surface, are layered. The primary fastener 7 is fixed to the front surface Sc of the concrete frame Cw, and the secondary fastener 10 is a cement plate Pa on the upper end surface of the heat insulating composite panel P. The protrusions 12b on the secondary fastener side are engaged with each other in the groove a, and are fixed to the primary fastener 7 by adjusting the front and rear, left and right, and the head 3 is fixed to the upper end of the panel P. It is supported via the fixed bracket 15 and is fixed to the concrete frame upper end surface Fc via the bottom plate 3D extending rearward, and the air in the interface gap as between the panel heat insulating layer Pb and the concrete frame front surface Sc. Stop distribution Is one that guarantees the air flow from the groove a group within the panel outwardly over the coping 3.

尚、コンクリート躯体Cwはパラペットを含むものである。
また、本発明にあっては、コンクリート躯体Cw前面Scに強固に固定した一次ファスナー7に対し、断熱複合パネルPを外壁前面が面一となるように二次ファスナー10を介して位置調整して一次ファスナー7に止着するため、コンクリート躯体前面Scの最大突出部とパネルPの断熱層Pbとは、図2(A),(B)の如く当接形態となるが、コンクリート躯体前面Scの不陸に対応した界面隙間asが大なり小なり各パネルPの内面(断熱層)とコンクリート躯体表面Sc間に生ずる。
The concrete frame Cw includes a parapet.
Further, in the present invention, the position of the heat insulating composite panel P is adjusted via the secondary fastener 10 so that the front surface of the outer wall is flush with the primary fastener 7 firmly fixed to the concrete housing Cw front surface Sc. In order to fix to the primary fastener 7, the maximum protrusion of the concrete housing front surface Sc and the heat insulating layer Pb of the panel P are in contact form as shown in FIGS. 2 (A) and 2 (B). The interfacial gap as corresponding to the unevenness is made larger or smaller between the inner surface (heat insulating layer) of each panel P and the concrete frame surface Sc.

しかし、界面隙間asに対しては、図9(A)の如く、パネル下端面への現場発泡断熱材9の注入によっても、図1(A),(B)の如く、パネル上端面へのアスファルトのルーフコーティング9cによっても空気流通阻止が達成され、界面隙間asの空気流通阻止は、パネルPの上端又は下端の界面隙間asを閉止するだけで良い。
また、二次ファスナー10の一次ファスナー7への前後左右調整の下での止着は、二次ファスナー10を一次ファスナー7に摺動形態で載置すれば前後左右調整が容易であり、両ファスナー10,7の止着は、慣用のボルト締着、ねじ止着、溶接等の採用が可能である。
However, for the interfacial gap as, as shown in FIG. 9 (A), injection of the in-situ foam heat insulating material 9 into the lower end surface of the panel also causes the upper end surface of the panel as shown in FIGS. 1 (A) and 1 (B). Air flow prevention is also achieved by the asphalt roof coating 9c, and the air flow prevention of the interface gap as only needs to close the interface gap as at the upper end or the lower end of the panel P.
Further, the fastening of the secondary fastener 10 to the primary fastener 7 under the front / rear / left / right adjustment is facilitated by adjusting the front / rear / left / right adjustment by placing the secondary fastener 10 on the primary fastener 7 in a sliding form. For the fastening of Nos. 10 and 7, conventional bolt fastening, screw fastening, welding or the like can be employed.

また、二次ファスナー10のパネルP上端の条溝aへの係止は、図1(A)の如く、条溝a内へ嵌入した突出片12bをセメント板Pa外面からねじ26で止着しても良く、或いは条溝aと嵌入突出片12bとの対応断面形状の設定によってパネルPを二次ファスナー10に確保しても良い。
勿論、係止状態でパネルPと二次ファスナー10とにガタツキが生じる場合は、セメント板Paと二次ファスナー突出片12bとをねじ締着すれば良い。
The secondary fastener 10 is locked to the groove a at the upper end of the panel P, as shown in FIG. 1A, by fixing the protruding piece 12b fitted into the groove a with a screw 26 from the outer surface of the cement board Pa. Alternatively, the panel P may be secured to the secondary fastener 10 by setting the corresponding cross-sectional shape of the groove a and the fitting protruding piece 12b.
Of course, if rattling occurs between the panel P and the secondary fastener 10 in the locked state, the cement plate Pa and the secondary fastener protruding piece 12b may be screwed together.

また、ブラケット15は、笠木3の前部を、笠木とパネルセメント板上端との間に空気流通スペースを介して支持出来れば良く、ブラケット15のパネルPの上端部への止着は、セメント板Pa上端面や、パネル上端に一体化固定した一次ファスナー7上面、二次ファスナー10上面等、に止着可能である。
また、笠木3は、前部がブラケット15で、後部が延出底板3Dのコンクリート躯体上面へのねじ26b止着で、前部と後部との2点支持で配置出来れば良く、アングル笠木形態でも十分な強度が付与出来、寸法、形状は、安価なアングル笠木形態で自在に設定すれば良い。
The bracket 15 only needs to be able to support the front portion of the headboard 3 via an air circulation space between the headboard and the upper end of the panel cement plate. It can be fastened to the Pa upper end surface, the upper surface of the primary fastener 7 integrally fixed to the upper end of the panel, the upper surface of the secondary fastener 10 or the like.
Further, the headboard 3 may be arranged with a bracket 15 at the front and a screw 26b fixed to the upper surface of the concrete frame of the extended bottom plate 3D at the rear, and can be arranged with two-point support of the front and rear. Sufficient strength can be imparted, and the dimensions and shape can be freely set in the form of an inexpensive angle headboard.

また、本発明にあっては、一次ファスナー7は、図4(A)に示す如く、長孔H7を有する水平片7F、及びボルト挿入用孔H70を有する垂直片7Wを備えたアングル鋼材であって、図1(A)の如く、コンクリート躯体前面Scに打込んだアンカーボルト7aに対し、垂直片7Wに配置したアンカーボルト7aの径より大径のボルト挿入用孔H70を介してアンカーボルト7aに位置調整の下でボルト締着するのが好ましい。
この場合、アンカーボルト7aをコンクリート躯体構築時に、コンクリート躯体に埋設しても良く、既存建物のコンクリート躯体へボルト孔を穿設して、あと施工アンカーボルト7aを打込んでも良く、本発明は、コンクリート建築物の新築にも、既存コンクリート建築物の外断熱改修にも有効に適用出来る。
In the present invention, the primary fastener 7 is an angle steel material provided with a horizontal piece 7F having a long hole H7 and a vertical piece 7W having a bolt insertion hole H70 as shown in FIG. As shown in FIG. 1A, the anchor bolt 7a is inserted into the anchor bolt 7a driven into the concrete body front surface Sc via a bolt insertion hole H70 having a diameter larger than the diameter of the anchor bolt 7a disposed on the vertical piece 7W. It is preferable to tighten the bolts under position adjustment.
In this case, the anchor bolt 7a may be embedded in the concrete frame at the time of construction of the concrete frame, or a bolt hole may be drilled in the concrete frame of an existing building and the post-installed anchor bolt 7a may be driven. It can be effectively applied to new construction of concrete buildings and renovation of existing concrete buildings.

また、乾式被覆外断熱構工法でのアンカーボルト7aは、典型的には径10mmのあと施工アンカーボルトであり、オールアンカー(サンコーテクノ(株)商品名)か、ネールアンカー(岡部建材(株)商品名)であって、アンカーボルト7a1本当り890kgfの引張荷重強度を発揮するものである。
また、垂直片7Wのボルト挿入用孔H70は径が20mm位であれば、アンカーボルト7aに対する一次ファスナー7の上下左右方向の位置調整機能が発揮出来る。
この場合、パネルP1枚当りの荷重は40kg弱であるので、アンカーボルト7aに対する垂直片7Wのボルト締着により、二次ファスナー10の十分な支持強度を発揮する。
また、水平片7Fの長孔H7は、一次ファスナー7上での二次ファスナー10のボルト止着の位置調整に有効である。
In addition, the anchor bolt 7a in the dry outer insulation method is typically a post-installed anchor bolt having a diameter of 10 mm, either an all anchor (trade name of Sanko Techno Co., Ltd.) or a nail anchor (Okabe Construction Materials Co., Ltd.). Product name), which exhibits a tensile load strength of 890 kgf per one anchor bolt 7a.
Moreover, if the diameter of the bolt insertion hole H70 of the vertical piece 7W is about 20 mm, the function of adjusting the position of the primary fastener 7 in the vertical and horizontal directions with respect to the anchor bolt 7a can be exhibited.
In this case, since the load per panel P is less than 40 kg, sufficient support strength of the secondary fastener 10 is exhibited by bolting the vertical piece 7W to the anchor bolt 7a.
Further, the long hole H7 of the horizontal piece 7F is effective for adjusting the position of the bolt fastening of the secondary fastener 10 on the primary fastener 7.

また、本発明にあっては、一次ファスナー7の水平片7Fが、図5の如く、長孔H7の下面に自在ナット金具8を備え、自在ナット金具8にはナット8Aを固定した座金8Bを摺動自在に保持させるのが好ましい。
この場合、摺動自在のナット8Aは、図5(A)の如く、座金8Bがナット8Aの共回りを抑制して一次ファスナー7の位置調整の下でのボルト締着を可能とし、ナット8Aが自在ナット金具8内に保持されているため、断熱層Pb上面に、図3(A)の切欠C2の如き自在ナット金具8のみの凹欠を施せば、少ない断熱層欠損で、且つ、きれいに一次ファスナー7のパネルP上端への取付けが出来る。
In the present invention, the horizontal piece 7F of the primary fastener 7 is provided with a free nut fitting 8 on the lower surface of the long hole H7 as shown in FIG. 5, and the free nut fitting 8 has a washer 8B to which a nut 8A is fixed. It is preferable to hold it slidably.
In this case, as shown in FIG. 5A, the slidable nut 8A allows the bolt 8 to be tightened under the position adjustment of the primary fastener 7 by the washer 8B suppressing the co-rotation of the nut 8A. Is retained in the universal nut fitting 8, so that if the concave portion of only the universal nut fitting 8 such as the notch C2 in FIG. The primary fastener 7 can be attached to the upper end of the panel P.

また、本発明にあっては、二次ファスナー10は、図4(B)の如く、長孔H10を有する水平片10Fの前端下面に断面台形の突出片12bを下方に突出し、断熱複合パネルPの断面台形の条溝a1に、二次ファスナー10の突出片12bを係止するのが好ましい。
この場合、二次ファスナーの突出片12bはセメント板条溝a1と対応係合し、且つ両者間にガタツキの生じない嵌合とすれば、二次ファスナー10によるパネル上端の係止が合理的に実施出来る。
この場合、条溝a1には、突出片12bの嵌入部下方で隣接条溝aとの境界のリブRに空気連通用の横断溝を配置すれば、係合用条溝a1内の空気流通Afが保証出来る。
そして、二次ファスナー10の長孔H10を一次ファスナー7の長孔H7と交差形態で設ければ、両ファスナー相互の位置調整の下でのボルト締着が合理的に実施出来る。
In the present invention, as shown in FIG. 4 (B), the secondary fastener 10 has a trapezoidal protruding piece 12b protruding downward on the lower surface of the front end of the horizontal piece 10F having the long hole H10. It is preferable that the protruding piece 12b of the secondary fastener 10 is locked to the groove a1 having a trapezoidal cross section.
In this case, if the protruding piece 12b of the secondary fastener is correspondingly engaged with the cement strip groove a1 and does not cause rattling, the upper end of the panel can be reasonably locked by the secondary fastener 10. Can be implemented.
In this case, if a transverse groove for air communication is arranged in the rib R at the boundary with the adjacent groove a below the fitting portion of the protruding piece 12b, the air flow Af in the engagement groove a1 is provided in the groove a1. Can be guaranteed.
And if the long hole H10 of the secondary fastener 10 is provided in the crossing form with the long hole H7 of the primary fastener 7, the bolt fastening under the positional adjustment of both fasteners can be implemented rationally.

断熱複合パネルPの外面を面一とする張設は、コンクリート躯体表面Scの不陸突出の最も大な部分でパネル断熱層Pb表面とコンクリート躯体表面Scとを当接形態とするのが両表面間での界面隙間asの発生を最少に抑えるために必要である。
Further, in the present invention, as shown in FIG. 4A, the primary fastener 7 has a longitudinal hole H7 in the horizontal piece 7F, and the secondary fastener 10 has a horizontal hole in the horizontal piece 10F. The secondary fastener 10 is preferably positioned on the primary fastener 7 and fastened with bolts through the longitudinal longitudinal hole H7 and the laterally elongated hole H10.
The tension of the heat insulating composite panel P to be flush with the outer surface of the heat insulating composite panel P is such that the surface of the panel heat insulating layer Pb and the surface of the concrete frame Sc are in contact with each other at the largest portion of the uneven surface of the concrete frame Sc. This is necessary in order to minimize the occurrence of the interfacial gap as.

また、各一次ファスナー7のそれぞれは、必ず垂直片7Wをコンクリート躯体表面Scに当接固定するのが強度保持上必要であり、コンクリート躯体表面Scの不陸対応により、各二次ファスナー10それぞれは、パネルPの面一化基準に沿って異なる前後位置調整量が必要となる。
そして、二次ファスナー10は突出片12bを備えておるため、十分な長さの前後長孔の配置は困難であるが、一次ファスナー7への前後長孔の配置は、かなり大寸の長孔まで配置可能となり、各二次ファスナー10のそれぞれの前後動調整の計測配置を容易にする。
そして、パネルPの面一配置は、前後位置調整の後に、必要量の左右位置調整をするのが好ましい。
従って、一次ファスナー7の強固な固着、及びパネルPの必要前後動調整の下での面一配置が合理的に実施出来る。
In addition, each primary fastener 7 must have the vertical piece 7W in contact with and fixed to the concrete housing surface Sc in order to maintain the strength. Due to the unevenness of the concrete housing surface Sc, each secondary fastener 10 is A different amount of front-rear position adjustment is required along the leveling standard of the panel P.
And since the secondary fastener 10 is provided with the protruding piece 12b, it is difficult to arrange the front and rear long holes with a sufficient length, but the arrangement of the front and rear long holes to the primary fastener 7 is a fairly large oblong hole. This makes it possible to easily measure and arrange the longitudinal movement adjustment of each secondary fastener 10.
And it is preferable to adjust the left-right position of the required amount after the front-back position adjustment.
Therefore, it is possible to rationally implement the firm fixing of the primary fastener 7 and the flush arrangement of the panel P under the necessary longitudinal movement adjustment.

また、本発明にあっては、断熱複合パネルPは、セメント板Paが少なくとも両端に断面台形の条溝a1を含む上下方向条溝a1,a2群を備え、断熱層Pbが各条溝a1,a2面上に成形発泡断熱材を積層一体化したものが好ましい。
断面台形の条溝a1は、二次ファスナー10の有する断面台形の突出片12bを嵌入するだけで二次ファスナー10によるパネルPの係止が達成出来る。
そして、二次ファスナー10によるパネルPの係止保持がパネルの左右両端となるため、各パネルPの面一化調整も容易となる。
Moreover, in this invention, the heat insulation composite panel P is provided with the vertical direction groove | channels a1 and a2 group in which the cement board Pa contains the groove | channel a1 of trapezoidal cross section at least at both ends, and the heat insulation layer Pb is each groove | channel a1, and. What laminated and integrated the molded foam heat insulating material on the a2 surface is preferable.
The trapezoidal groove a1 having the trapezoidal cross section can achieve the locking of the panel P by the secondary fastener 10 only by inserting the protruding piece 12b having the trapezoidal cross section of the secondary fastener 10.
And since the latching holding | maintenance of the panel P by the secondary fastener 10 becomes the right-and-left both ends of a panel, the equalization adjustment of each panel P becomes easy.

また、本発明にあっては、ブラケット15が、笠木3係止用の水平片15Uと、垂直片15Fと、底板15Dとを備えているのが好ましい。
この場合、ブラケット15は、図6(C)に示す如き形態となるため、垂直片15Fは、笠木3に対する空気流通Afの通気スペース確保が出来、底板15Dを二次ファスナー水平片10F上か、一次ファスナー水平片7Fかにねじ止着することによりブラケット15の固定が容易であり、笠木3の前部を、水平片15Uによって条溝a群からの空気流通可能に確保出来る。
そして、ブラケット15を二次ファスナー水平片10F上の定点位置に止着すれば、笠木3のコンクリート躯体前面Scに対する不陸対応となる。
In the present invention, it is preferable that the bracket 15 includes a horizontal piece 15U for locking the headboard 3, a vertical piece 15F, and a bottom plate 15D.
In this case, since the bracket 15 has a form as shown in FIG. 6C, the vertical piece 15F can secure a ventilation space for the air flow Af to the headboard 3, and the bottom plate 15D is placed on the secondary fastener horizontal piece 10F. The bracket 15 can be easily fixed by screwing it to the primary fastener horizontal piece 7F, and the front portion of the headboard 3 can be secured by the horizontal piece 15U so that air can flow from the groove a group.
And if the bracket 15 is fixed to the fixed point position on the secondary fastener horizontal piece 10F, it will become the non-land response | compatibility with respect to the concrete frame front surface Sc of the headboard 3. FIG.

また、本発明にあっては、2つの長孔H7を左右に設けた一次ファスナー7を断熱複合パネルPの左右接続部d3上に配置し、一つの突出片12b及び長孔H10を備えた二次ファスナー10の2個を1個の一次ファスナー7上の左右に配置するのが好ましい。
この場合、1個の二次ファスナー10が1枚のパネルPの一端部毎の対応となるため、一次ファスナー7上への位置決めの自由度が増し、パネルPの面一化調整及びパネルPの一次ファスナー7上への載置係合作業が容易となる。
In the present invention, the primary fastener 7 provided with two long holes H7 on the left and right sides is disposed on the left and right connection part d3 of the heat insulating composite panel P, and the two protrusions 12b and the long holes H10 are provided. Two of the secondary fasteners 10 are preferably arranged on the left and right on the primary fastener 7.
In this case, since one secondary fastener 10 corresponds to each one end portion of one panel P, the degree of freedom of positioning on the primary fastener 7 is increased, and the panel P is made uniform and adjusted. The placement engagement work on the primary fastener 7 becomes easy.

また、本発明にあっては、ブラケット15の底板15Dを2個の二次ファスナー10間に止するのが好ましい。
この場合、図7(B)に示す如く、2個の二次ファスナー10は一次ファスナー7上に分離形態で載置止着することとなり、各パネルPの左右接続部d3のそれぞれ両側パネル端に係止する二次ファスナー10間へのブラケット15の配置が可能となって、各ブラケット15は等間隔配置により笠木3の均斉確保が可能となり、パネル端部毎での前後左右位置調整の不要な一次ファスナー7上への止着作業となって取付けが容易である。
In the present invention, the bottom plate 15D of the bracket 15 is preferably stopped between the two secondary fasteners 10.
In this case, as shown in FIG. 7B, the two secondary fasteners 10 are placed and fixed on the primary fastener 7 in a separated form, and are attached to the respective side panel ends of the left and right connecting portions d3 of each panel P. The brackets 15 can be disposed between the secondary fasteners 10 to be locked, and the brackets 15 can be secured at equal intervals by arranging the brackets 15 at an equal interval. Mounting is easy because it is a fastening operation on the primary fastener 7.

また、本発明にあっては、笠木3は、図6に示す如く、立下り板3Fと、立下り板上端から後方に連なる天端水平板3Uと、天端水平板3U後部から立上り片3Bを介して後方に延出する底板3Dとを備え、図1(A)の如く、天端水平板3U下面と立下り板3F上部突起3Mで形成した係合溝3Gに、ブラケット先端を嵌入係止するのが好ましい。   Further, in the present invention, as shown in FIG. 6, the headboard 3 includes a falling plate 3F, a top end horizontal plate 3U continuous from the top of the falling plate to the rear, and a rising piece 3B from the rear of the top end horizontal plate 3U. And a bottom plate 3D extending rearward through the bracket, and as shown in FIG. 1A, the bracket tip is fitted into the engagement groove 3G formed by the lower surface of the top end horizontal plate 3U and the upper projection 3M of the falling plate 3F. It is preferable to stop.

この形態の笠木3にあっては、底板3Dによるコンクリート躯体Cw上面への固定と、天板3U先端のブラケット15による係止との前後2点保持となり、パラペットにも屋上にも適用可能な安価なアングル笠木形態でありながら、パラペットにしか適用出来ない高価なオープン笠木と同様の前後2点支持が達成出来、空気流通Afのためのスペースを備えたために、あおり風を受けてガタツキ易い笠木3が強固に保持出来る。
また、取付けに際しても、パネルPの上端部に止着したブラケット15に前部を係止した後の後部の固定となるため、笠木3の適正位置への止着が容易となる。
In the headboard 3 of this form, it is fixed to the top surface of the concrete frame Cw by the bottom plate 3D and is held at two points in the front and back by the bracket 15 at the tip of the top plate 3U, and can be applied to both the parapet and the rooftop. This is the shape of the angle headboard, but it can achieve two-point support similar to the expensive open headboard that can only be applied to parapets, and has a space for air circulation Af. Can be held firmly.
In addition, since the rear portion is fixed after the front portion is locked to the bracket 15 fixed to the upper end portion of the panel P, it is easy to fix the headboard 3 to an appropriate position.

また、本発明にあっては、断熱複合パネルPの断熱層Pbには、図3(A)に示す如く、上端及び内表面上部の全幅に亘る切欠C1を一次ファスナー7の板厚に対応して配置し、且つ、該パネルP両端部には、該切欠C1上に、更に自在ナット金具8等、二次ファスナー10止着対応の切欠C2を配置するのが好ましい。
該切欠C1,C2の付与は、工場等、別の場所での作業となって均質付与が容易であると共に、図1(B)及び図2(B)に示す如く、外壁上部施工時の断熱層Pbの切欠C1に対する石綿セメント板等の板材18での後処理作業が均斉、且つ容易に実施出来る。
また、深い部分切欠C2の存在により、二次ファスナー10締着ボルトの突出部の受け入れも可能となり、図1(A)の如く、下面に突出する自在ナット金具8を供えた一次ファスナー7の断熱複合パネルPへの配置もスムーズに実施出来、作業性が向上する。
Further, in the present invention, the heat insulating layer Pb of the heat insulating composite panel P has a notch C1 extending over the entire width of the upper end and the upper inner surface corresponding to the plate thickness of the primary fastener 7 as shown in FIG. Further, it is preferable to dispose a notch C2 corresponding to the fastening of the secondary fastener 10 such as a free nut fitting 8 on the notch C1 at both ends of the panel P.
The notches C1 and C2 are applied in a different place such as a factory so that uniform application is easy. In addition, as shown in FIGS. The post-treatment work with the plate material 18 such as asbestos-cement board can be performed uniformly and easily with respect to the notch C1 of the layer Pb.
Further, the presence of the deep partial cutout C2 allows the protrusion of the fastening bolt of the secondary fastener 10 to be received, and as shown in FIG. 1A, the heat insulation of the primary fastener 7 provided with the universal nut fitting 8 protruding on the lower surface. Arrangement on the composite panel P can be performed smoothly, and workability is improved.

本発明の通気性外断熱外壁の上部構造は、図1(A)及び図2(A)に示す如く、コンクリート躯体Cwの表面Scに一次ファスナー7を強固に当接固定し、一次ファスナー7に対してパネル上端に係止した二次ファスナー10を前後左右位置調整して固定するため、コンクリート躯体表面Scの不陸に関係なく、各断熱複合パネルP群を面一に張設出来る。
しかも、各パネルPを面一に張設したために生ずるパネル断熱層Pbとコンクリート躯体表面Scとの間に生ずる界面隙間asの空気流通を阻止したため、該隙間as内の空気層は流通しない密閉空気層となって空気断熱層の機能を奏し、パネル断熱層Pbと共にコンクリート躯体Cwに対する外断熱機能を奏する。
As shown in FIGS. 1 (A) and 2 (A), the upper structure of the breathable outer heat insulating outer wall of the present invention is such that the primary fastener 7 is firmly abutted and fixed to the surface Sc of the concrete housing Cw. On the other hand, since the secondary fastener 10 locked to the upper end of the panel is fixed by adjusting the front / rear / left / right positions, the heat insulating composite panels P can be stretched flush with each other regardless of the unevenness of the concrete housing surface Sc.
Moreover, since air flow in the interfacial gap as generated between the panel heat insulating layer Pb and the concrete housing surface Sc generated by stretching the panels P in a plane is prevented, the air layer in the gap as does not flow. It becomes a layer and has the function of an air insulating layer, and has an outer heat insulating function for the concrete frame Cw together with the panel heat insulating layer Pb.

更に、断熱複合パネルPは、密着層型でありながら条溝a群から笠木3を介した外方への空気流通Afを保証したため、セメント板Paと断熱層Pbとの界面が下方から上方への通気層となり、従来の密着層型パネル特有のセメント板等の外装材と断熱層との界面での結露を生ずる問題が解決出来る。
従って、断熱層Pbの吸湿による断熱機能低下が阻止出来ると共に、条溝aでの通気によるセメント板Paの日射による高温化も抑制出来、セメント板Paの耐用時のヒートストレスによる劣下も抑制出来、長期に亘る均質な外断熱機能、及び耐久性を備えた外壁の提供を可能にする。
Furthermore, since the heat insulating composite panel P guarantees the air flow Af from the groove a group to the outside through the headboard 3 while being an adhesion layer type, the interface between the cement board Pa and the heat insulating layer Pb is upward from the lower side. This can solve the problem of dew condensation at the interface between the heat-insulating layer and the exterior material such as a cement board peculiar to the conventional adhesive layer panel.
Accordingly, it is possible to prevent the heat insulation function from being deteriorated due to moisture absorption of the heat insulating layer Pb, to suppress the high temperature due to the solar radiation of the cement plate Pa due to the ventilation in the grooves a, and to suppress the deterioration due to the heat stress when the cement plate Pa is used. It is possible to provide an outer wall having a long-term uniform outer heat insulating function and durability.

更に、コンクリート躯体前面Scに当接固定した一次ファスナー7に対して、前後左右調整して止着する二次ファスナー10の突出片12bでのセメント板Paの条溝aへの係合によって断熱複合パネルPを張設するため、パネルPの張設作業が容易であり、パネルP群の面一化配置作業が容易である。
更に、笠木3も、前部をパネル上端部に止着したブラケット15を介して支持し、後部を後方に延出した底板3Dを介してコンクリート躯体Cwの上端面Fcに止着するため、パネル上端面に対して排気用の間隔を有し、あおり風を受ける笠木が、前後2点支持となって強固に保持出来、安価(オープン笠木の1/3)なアングル笠木形態の採用が可能となる。
Furthermore, with respect to the primary fastener 7 that is in contact with and fixed to the concrete housing front surface Sc, the heat insulating composite is achieved by engaging the cement plate Pa with the groove a in the protruding piece 12b of the secondary fastener 10 that is fixed by adjusting the front and rear, right and left. Since the panel P is stretched, the panel P is easily stretched, and the panel P group is easily arranged.
Further, the headboard 3 also supports the front portion via a bracket 15 fixed to the upper end portion of the panel, and fixes the rear portion to the upper end surface Fc of the concrete frame Cw via a bottom plate 3D extending rearward. It has a space for exhaust with respect to the upper end surface, and the headboard that receives the wind of the wind can be supported firmly at the front and rear two points, and it is possible to adopt an inexpensive angle headboard form (1/3 of the open headboard). Become.

また、一次ファスナー7は、アングル形態の鋼材の垂直片7Wの大径のボルト挿入用孔H70を、コンクリート躯体Cwに打込んだ小径のアンカーボルトに嵌合して強固に固定するため、一次ファスナー7のコンクリート躯体Cwの表面Scに対する上下左右の位置調整の下での固着が出来、パネルPの張設は、コンクリート躯体Cwの前後方向不陸のみならず、上下方向不陸にも対処可能となり、コンクリート躯体Cwの、不陸の特に多い既存コンクリート建築物の外断熱への改修施工に、特に有効である。   In addition, the primary fastener 7 is a primary fastener because the large-diameter bolt insertion hole H70 of the vertical piece 7W of the angle-shaped steel material is fitted and firmly fixed to the small-diameter anchor bolt driven into the concrete frame Cw. 7 can be fixed with respect to the surface Sc of the concrete frame Cw under vertical and horizontal position adjustments, and the panel P can be applied not only to the front / rear direction of the concrete case Cw but also to the uneven direction of the vertical direction. It is particularly effective for the renovation of the concrete frame Cw to the external insulation of existing concrete buildings that are particularly uneven.

また、一次ファスナー7は、水平片7F下面にナット8Aを固定した座金8Bを摺動自在に保持した自在ナット金具8を有するため、一次ファスナー7上での二次ファスナー10の位置調整摺動が、仮止め状態でのボルト13aの自在ナット金具8内での座金8Bの摺動となり、微調整摺動がスムーズに実施出来る。
また、二次ファスナー10は、下方突出の断面台形突出片12bを、パネルセメント板Paの断面台形の条溝a1内に嵌入係止するため、二次ファスナー10による断熱複合パネルP上端の係止保持作業が容易となる。
Further, since the primary fastener 7 has a universal nut fitting 8 that slidably holds a washer 8B with a nut 8A fixed on the lower surface of the horizontal piece 7F, the position adjustment sliding of the secondary fastener 10 on the primary fastener 7 can be performed. The washer 8B slides within the universal nut 8 of the bolt 13a in the temporarily fixed state, and fine adjustment sliding can be smoothly performed.
Moreover, since the secondary fastener 10 fits and locks the downwardly protruding cross-sectional trapezoidal protruding piece 12b into the cross-sectionally trapezoidal groove a1 of the panel cement board Pa, the secondary fastener 10 is locked at the upper end of the heat insulating composite panel P. Holding work becomes easy.

また、二次ファスナー10の一次ファスナー7上での前後左右位置調整は、一次ファスナー7の前後方向長孔H7と、二次ファスナー10の左右方向長孔H10とに、ボルト13aを挿通して自在ナット金具8内のナット8Aに仮止めして実施するため、パネル断熱層Pbに支障を生ずることなくスムーズに実施出来、自在ナット金具8を収納する断熱層Pb上の切欠C2も、断熱層Pbの内表面からの自在ナット金具8の幅に対応する細幅の切欠と出来、切欠C2の形成が断熱層Pbの欠損の最少限の下に容易に出来る。   In addition, the front / rear / left / right position adjustment on the primary fastener 7 of the secondary fastener 10 can be freely performed by inserting a bolt 13a through the front / rear direction long hole H7 of the primary fastener 7 and the left / right direction long hole H10 of the secondary fastener 10. Since it is temporarily fixed to the nut 8A in the nut metal fitting 8, it can be carried out smoothly without causing any trouble to the panel heat insulating layer Pb, and the notch C2 on the heat insulating layer Pb housing the universal nut metal 8 is also provided in the heat insulating layer Pb. A notch with a narrow width corresponding to the width of the universal nut fitting 8 from the inner surface can be formed, and the formation of the notch C2 can be easily performed under the minimum of the defect of the heat insulating layer Pb.

また、1個の一次ファスナー7に対して2個の二次ファスナー10を分割形態で配置するため、各パネルPのそれぞれが端部で位置調整可能となり、各パネルP群の位置微調整の下での取付作業が容易となって、パネルの適正配置に有利である。
しかも、笠木3係止用のブラケット15も二次ファスナー10間で一次ファスナーに取付可能となり、ブラケット15の取付合理化と、ブラケット15の等間隔配置による笠木3の均斉な保持が可能となる。
In addition, since the two secondary fasteners 10 are arranged in a divided form with respect to one primary fastener 7, the position of each panel P can be adjusted at the end, and the position of each panel P group can be adjusted finely. This facilitates the mounting work and is advantageous for proper panel placement.
In addition, the bracket 15 for locking the cap 3 can be attached to the primary fastener between the secondary fasteners 10, so that the mounting of the bracket 15 can be rationalized and the cap 3 can be held uniformly by arranging the brackets 15 at equal intervals.

The projecting pieces 12a and 12b are disposed at a position where the projecting length is about plus 20 mm.
The reason why the trapezoidal grooves a1 are arranged in pairs in the center is that the cement plate Pa is divided into two in the width direction on the center rib R to enable use in a 1/2 width size.

[Formation of the superstructure of the outer wall (FIGS. 1 and 8)]
The present invention is applied to a dry-coating repair outer heat insulating construction method for an existing concrete building.
First, the front end portion of the waterproof layer 9a on the upper surface of the concrete frame Cw of the existing building and the concrete frame front surface Sc are prepared so as to be able to be repaired, and the concrete frame Cw is marked with reference ink, and as shown in FIG. A hole with a diameter of 10.5 mm is drilled in the front surface Sc of the housing, and after 10 mm in diameter, a construction anchor bolt 7a (Sanko Techno Co., Ltd. trade name: All Anchor, Okabe Construction Materials Co., Ltd. trade name: Nail Anchor, etc.) is inserted. The core rod at the center of the post-installed anchor bolt 7a is driven with a hammer so that the tip of the post-installed anchor bolt is opened in the concrete, and a tensile load strength of 890 kgf is applied to each anchor bolt 7a.

次いで、図1(A)の如く、一次ファスナー7の垂直片7Wのボルト挿入用孔H70(孔径:20mm)をアンカーボルト7aの突出部に嵌合し、径12mmのボルト用孔を有する座金7bを介してナット7cを強固に締着する。
この場合、一次ファスナーの孔H70は径が20mmであり、アンカーボルト径が10mmであるので、アンカーボルト7aと一次ファスナー7とを、上下左右の必要位置微調整の下に強固に締着する。
Next, as shown in FIG. 1A, the bolt insertion hole H70 (hole diameter: 20 mm) of the vertical piece 7W of the primary fastener 7 is fitted into the protruding portion of the anchor bolt 7a, and the washer 7b having a bolt hole with a diameter of 12 mm. The nut 7c is firmly tightened via
In this case, since the hole H70 of the primary fastener has a diameter of 20 mm and the anchor bolt diameter is 10 mm, the anchor bolt 7a and the primary fastener 7 are firmly fastened under the necessary fine adjustment of the vertical and horizontal directions.

パネル1枚当りの負荷重量は45kg前後であり、一次ファスナー7は、図8(A)の如く、各パネルPの接続目地d3の位置に配置するので、各一次ファスナー7による各パネルPの適正支持が可能となる。
次いで、固定された一次ファスナー7の水平片7Fの一方の長孔H7上に、パネルP一端の条溝a1に下方突出片12bを係止した二次ファスナー10の水平片10Fを載置し、両ファスナー7,10のボルト挿入用孔H7,H10を重ねて径10mmのボルト13aを座金13bを介して一次ファスナー7下面の自在ナット金具8内のナット8Aに挿通仮止めし、二次ファスナー10を前後方向長孔H7、左右方向長孔H10によって位置調整した後、ボルト13aを一体化座金8Bで回動の制限されたナット8Aに強固に締着する。
The load weight per panel is about 45 kg, and the primary fastener 7 is arranged at the connection joint d3 of each panel P as shown in FIG. Support is possible.
Next, the horizontal piece 10F of the secondary fastener 10 in which the downward projecting piece 12b is locked to the groove a1 at one end of the panel P is placed on one elongated hole H7 of the horizontal piece 7F of the fixed primary fastener 7, The bolt insertion holes H7 and H10 of both fasteners 7 and 10 are overlapped, and a bolt 13a having a diameter of 10 mm is inserted and temporarily fixed to the nut 8A in the free nut fitting 8 on the lower surface of the primary fastener 7 through the washer 13b. After the position of the bolt 13a is adjusted by the front and rear direction long hole H7 and the left and right direction long hole H10, the bolt 13a is firmly fastened to the nut 8A whose rotation is restricted by the integrated washer 8B.

同様に、他方のパネル他端の条溝a1に係止した二次ファスナー10を一次ファスナー7の他方の長孔H7にボルト締着し、図8(A)の如く、パネル接続部d3上に配置した1個の一次ファスナー7上には、各パネルP端の上面を係止した二次ファスナー10の2個を締着する。   Similarly, the secondary fastener 10 locked in the groove a1 at the other end of the other panel is bolted to the other elongated hole H7 of the primary fastener 7, and as shown in FIG. 8A, on the panel connection portion d3. On the one primary fastener 7 arranged, two secondary fasteners 10 that lock the upper surface of each panel P end are fastened.

そして、図1(B)の如く、一次ファスナー水平片7F間の断熱層切欠C1には、一次ファスナー水平片7Fと等厚の石綿セメント板18(JISA5403石綿スレート)を接着して断熱層Pb上面の切欠C1を補修する。
次いで、図7(A),(B)に示す如く、一次ファスナー水平片7F上の両側の二次ファスナー10間には、所定位置にブラケット15の底板15Dをドリルスクリュー(サンコーテクノ(株)商品名)等のねじ26aで一次ファスナー水平片7Fに締着し、ブラケット15を各パネル間隔で配置する。
Then, as shown in FIG. 1 (B), the asbestos cement board 18 (JISA5403 asbestos slate) having the same thickness as the primary fastener horizontal piece 7F is bonded to the heat insulation layer notch C1 between the primary fastener horizontal pieces 7F, and the upper surface of the heat insulation layer Pb. Repair notch C1.
Next, as shown in FIGS. 7A and 7B, between the secondary fasteners 10 on both sides of the primary fastener horizontal piece 7F, the bottom plate 15D of the bracket 15 is drilled into a predetermined position with a drill screw (product of Sanko Techno Co., Ltd.). The first fastener horizontal piece 7F is fastened with a screw 26a such as a name), and the brackets 15 are arranged at intervals of each panel.

また、コンクリート躯体上端前面では、既存防水層9a前縁からパネルP上端後部に亘り、アスファルトのルーフコーティング9cを付与して、図1(B)、図2(B)の如く、コンクリート躯体前面Scとパネル断熱層Pb間の界面隙間asを閉止する。
この場合、界面隙間asの大な部所は、必要に応じてバックアップ材19´を充填してルーフコーティング9cを施工する。
また、図8(B),(C)に示す如く、従来例1,2同様に、セメント板(外装材)表面からあと施工アンカー24をコンクリート躯体Cwに打込む。
また、必要に応じて、セメント板Paを、図1(A)の如く、ねじ26によって二次ファスナー突出片12bの面板12Pに止着する。
Further, asphalt roof coating 9c is applied from the front edge of the existing waterproof layer 9a to the rear end of the upper end of the panel P on the front surface of the concrete casing upper end, as shown in FIGS. 1B and 2B, Sc. And the interface gap as between the panel heat insulating layer Pb is closed.
In this case, a large portion of the interfacial gap as is filled with the backup material 19 ′ as necessary to apply the roof coating 9c.
Further, as shown in FIGS. 8B and 8C, the post-construction anchor 24 is driven into the concrete frame Cw from the surface of the cement board (exterior material) as in the conventional examples 1 and 2.
If necessary, the cement plate Pa is fastened to the face plate 12P of the secondary fastener protruding piece 12b with a screw 26 as shown in FIG.

次いで、笠木3は、図1(A)の如く、一次ファスナー水平片7F上に固定したブラケット15の水平片15U先端に、天端水平板3U下面前端の係合溝3Gを嵌合係止し、後方に延出した底板3D後部を既存防水層9a上からコンクリート躯体(パラペット)Cw上端面Fcにねじ26bで固定する。
この場合、既存防水層9a上が不陸であれば、必要に応じて底板3Dと防水層9a間にパッキンを介在する。
Next, as shown in FIG. 1A, the cap 3 is fitted and locked with the engaging groove 3G at the front end of the lower surface of the top horizontal plate 3U at the tip of the horizontal piece 15U of the bracket 15 fixed on the horizontal piece 7F of the primary fastener. The rear portion of the bottom plate 3D extending rearward is fixed to the concrete casing (parapet) Cw upper end face Fc with screws 26b from the existing waterproof layer 9a.
In this case, if the existing waterproof layer 9a is not flat, a packing is interposed between the bottom plate 3D and the waterproof layer 9a as necessary.

また、笠木底板3D上には新規防水層9bを立上り片3Bと当接形態で張設し、防水層9bと天端水平板3Uの下面との間にはシーリング19を施す。
また、各パネル左右接続部d3では、図8(C)の如く、セメント板Paと断熱層Pbとの接着時に付与した段差d1(10mm)と段差d2(20mm)によって、断熱層Pbの当接界面Bbは、セメント板Pa面上に位置するが、両セメント板Pa端間は10mm幅の断熱層Pbむき出しの接続部d3となるため、該接続部d3には、バックアップ材19´を介してシーリング19を施す。
Further, a new waterproof layer 9b is stretched in contact with the rising piece 3B on the cap board bottom plate 3D, and a sealing 19 is provided between the waterproof layer 9b and the lower surface of the top end horizontal plate 3U.
Moreover, in each panel right-and-left connection part d3, as shown in FIG. 8C, the contact between the heat insulating layer Pb is caused by the step d1 (10 mm) and the step d2 (20 mm) applied when the cement plate Pa and the heat insulating layer Pb are bonded. The interface Bb is located on the cement board Pa surface, but since the space between both ends of the cement board Pa is a 10 mm-wide heat-insulating layer Pb-exposed connection part d3, the connection part d3 has a backup material 19 ′ interposed therebetween. Sealing 19 is applied.

尚、外壁の中間部、即ちパネルの上下接続構造も、上部構造同様に、一次ファスナー7と、変形二次ファスナー21で施工出来る。
図9は、各断熱複合パネルPの上下接続部の説明図であって、上下接続部d4にあっては、本発明のパネル上端取付けに採用したアングル鋼材の一次ファスナー7を、図9(A)の如く、アンカーボルト7aを採用してコンクリート躯体Cwの前面に固着し、二次ファスナーは、図9(B)の如く、水平片21Fの後端上下に、上方では、上下接続部d4の目地高さを確保するための高さh21を備えた台板21a上に上方視断面台形の突出片12aの一対を、下方では、上方突出片12aの対応位置で上方突出片12aと同形状の下方突出片12bの一対を備えたものである。
In addition, the intermediate part of the outer wall, that is, the upper and lower connection structure of the panel can be constructed by the primary fastener 7 and the modified secondary fastener 21 similarly to the upper structure.
FIG. 9 is an explanatory view of the upper and lower connecting portions of each heat insulating composite panel P. In the upper and lower connecting portion d4, the primary fastener 7 of the angle steel material adopted for the panel upper end mounting of the present invention is shown in FIG. As shown in FIG. 9 (B), the secondary fastener is fixed to the front surface of the concrete frame Cw using the anchor bolt 7a. A pair of protruding pieces 12a having a trapezoidal shape in an upper sectional view is provided on a base plate 21a having a height h21 for securing a joint height, and a lower portion has the same shape as the upper protruding piece 12a at a position corresponding to the upper protruding piece 12a. A pair of downward projecting pieces 12b is provided.

そして、二次ファスナ21は、上下突出片12a,12bによって、上方パネル下端と下方パネル上端とを係止し、二次ファスナー長孔H21を一次ファスナー長孔H7に合致させてボルト13aを挿通し、位置調整の下に一次ファスナー7にボルト締着する。
そして、接続部d4の二次ファスナー21の存在しない空間部から現場発泡断熱材9を上下断熱層Pb間に注入して条溝a群を閉止しないように充填し、接続部d4全長に亘って、条溝a群を閉止しないようにバックアップ材19´を介してシーリング19を施す。
そして、現場発泡断熱材9の注入は、最奥部から断熱層Pbの切欠C1を含む上下断熱層Pb間を充填埋設するため、パネルP間の上下接続部d4での断熱損失は生じない。
Then, the secondary fastener 21 is engaged with the upper panel lower end and the lower panel upper end by the upper and lower protruding pieces 12a, 12b, the secondary fastener long hole H21 is aligned with the primary fastener long hole H7, and the bolt 13a is inserted. The bolt is fastened to the primary fastener 7 under the position adjustment.
Then, the in-situ foam heat insulating material 9 is injected between the upper and lower heat insulating layers Pb from the space where the secondary fastener 21 of the connecting portion d4 does not exist, and is filled so as not to close the groove a group, over the entire length of the connecting portion d4. The sealing 19 is applied through the backup material 19 'so as not to close the groove a group.
And since the injection | pouring of the in-situ foam heat insulating material 9 fills and embeds between the upper and lower heat insulation layers Pb including the notch C1 of the heat insulation layer Pb from the innermost part, the heat insulation loss in the upper and lower connection part d4 between the panels P does not arise.

以上の如く、断熱複合パネルP群をコンクリート躯体前面Scに取付けた外断熱外壁の上部構造にあっては、並列接続部d3では、断熱層Pbの当接界面Bbがセメント板Pa面で閉止されて当接界面Bbへの空気侵入が完全阻止され、接続部d3での断熱機能低下が阻止出来、またパネル断熱層Pbとコンクリート躯体前面Scとの界面隙間asも、上端がアスファルトのルーフコーティング9cで閉止されて界面隙間as内は密閉空気層として断熱機能を発揮するため、断熱複合パネルPを備えた外壁は、設計値どおりの外断熱機能を発揮する。
そして、上下接続部d4では、下方パネル条溝aから上方パネル条溝aへの空気流通が可能であるため、外壁パネルの下端から上端の笠木3を介した外方への空気流通Afが保証される。
As described above, in the upper structure of the outer heat insulating outer wall in which the heat insulating composite panel P group is attached to the concrete housing front surface Sc, the contact interface Bb of the heat insulating layer Pb is closed on the cement plate Pa surface in the parallel connection portion d3. As a result, air intrusion into the contact interface Bb is completely prevented, the deterioration of the heat insulation function at the connection part d3 can be prevented, and the interfacial gap as between the panel heat insulation layer Pb and the concrete housing front surface Sc also has an asphalt roof coating 9c. The outer wall provided with the heat insulating composite panel P exhibits the outer heat insulating function as designed, because the inside of the interface gap as is closed and closed and exhibits the heat insulating function as a sealed air layer.
In the upper and lower connection part d4, since air can flow from the lower panel groove a to the upper panel groove a, the air flow Af from the lower end of the outer wall panel to the outside through the headboard 3 is guaranteed. Is done.

また、各一次ファスナー7は、全てコンクリート躯体Cwの前面Scに当接固定するため、アンカーボルト7aによって強固に固定出来、各パネルPは、コンクリート躯体前面Scの不陸突出最大部位を基準とし、コンクリート躯体表面Scの不陸凹部では、パネルPとコンクリート躯体表面Sc間に界面隙間asを形成しながら面一に張設するため、建築後15〜20年経過したコンクリート躯体表面に1mにつき10mm以上の不陸の存在するコンクリート建物であっても、外壁面、即ちパネルセメント板Pa表面がきれいに面一化された高性能外断熱建築物に改修出来る。   In addition, since each primary fastener 7 is abutted and fixed to the front surface Sc of the concrete frame Cw, it can be firmly fixed by the anchor bolt 7a. Each panel P is based on the maximum uneven protrusion of the concrete frame front surface Sc. At the uneven surface of the concrete body surface Sc, it is stretched flush with the panel P and the concrete body surface Sc while forming an interfacial gap as, so the surface of the concrete body 15 to 20 years after construction is 10 mm or more per meter Even in a concrete building where there is unevenness, it can be repaired to a high-performance external heat insulating building in which the outer wall surface, that is, the surface of the panel cement board Pa is cleanly made uniform.

本発明は、コンクリート建築物の新築時には、アンカーボルト7aをコンクリート躯体Cw前面に、コンクリート打設時に埋設すれば、打設コンクリート躯体Cwの前面Scに不陸が生じても、簡単、且つ合理的に断熱複合パネルPの面一張着が出来るが、建築後15年以上経過した、既存コンクリート建築物にあっては、コンクリート躯体外面の不陸が普通であるため、既存コンクリート建築物を乾式被覆改修で外断熱建築物に更生するために適用すれば特に有効である。
従って、本発明は、特に、コンクリート建築物の改修に極めて有利な、実用性の高い発明である。
In the present invention, when a concrete building is newly constructed, if the anchor bolt 7a is embedded in the front surface of the concrete frame Cw and embedded in the concrete, even if unevenness occurs on the front surface Sc of the cast concrete frame Cw, it is simple and rational. Insulating composite panels P can be installed on the same surface, but in existing concrete buildings that have been built for more than 15 years, the outer surface of the concrete frame is usually uneven, so the existing concrete buildings are dry-coated. It is particularly effective when applied to rehabilitate exterior heat-insulated buildings by renovation.
Therefore, the present invention is a highly practical invention that is extremely advantageous particularly for the repair of concrete buildings.
