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外断熱コンクリート建物に改修出来、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 where there is a risk of contamination, and concrete buildings that have become dirty or obsolete, and as with newly constructed external insulation concrete buildings, it is possible to prevent dew condensation and to provide healthy exterior insulation concrete buildings It can be renovated into a concrete building that is energy-saving and durable.

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, “Standard Specification for Building Construction, Remarks (JASS5) Reinforced Concrete Construction” 1997 edition, the unevenness of the outer wall surface is less than 10 mm per 3 m for tiles and 10 mm per 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13)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)があっても、断熱複合パネルのコンクリート躯体外面に対する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 type cover repair method of Conventional Example 1 (Fig. 13), 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 (surface unevenness) on the outer surface of the concrete frame. However, since it is impossible to adjust the heat-insulating composite panel in the front-rear direction with respect to the outer surface of the concrete frame, 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 beat the projecting surface of the concrete frame prior to tensioning of the heat insulating composite panel. Moreover, it is difficult to make the surface of the concrete frame 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、内面の条溝群は密閉空気層としての断熱機能を奏するだけであり、密着層型のパネル内に通気層が存在しない。
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による断熱材の機能低下の問題を有する。
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 apparent from the above, the groove group on the inner surface only has a heat insulating function as a sealed air layer, and there is no air-permeable layer in the adhesion layer type panel.
Therefore, the outer wall of the panel is inferior due to heat stress due to the high temperature of the cement board due to solar radiation, and between the heat insulating layer and the cement board, the heat insulating material due to the interface dew condensation peculiar to the adhesion layer type outer heat insulating composite panel is used. Has the problem of functional degradation.

また、従来例2(図14)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は作業性が悪く、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。
Moreover, even in the dry-type cover repair construction method of the conventional example 2 (FIG. 14), the 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 It is also necessary to stretch the heat-insulating composite panel with the turning work, and the workability is poor, and it is difficult to make the outer wall surface uniform.
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. Provides a new outer wall structure that can be constructed with good workability and good workability. Moreover, it is an adhesion layer type heat insulating composite panel, but it penetrates the upper and lower continuous panels from the drainage of the lower end of the outer wall and penetrates the upper end of the top panel. The present invention provides an outer wall structure that allows air to be ventilated, and solves the problems of Conventional Example 1 and Conventional Example 2 at a time as described above.

本発明は、例えば、図2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、図3に示す如き、各水平片と垂直片のアングル形態の、下端一次ファスナー6及び中間一次ファスナー7と、図5に示す如き、各水平片形態の片面に突出片12aを備えた片面二次ファスナー10及び両面に突出片12a,12bを備えた両面二次ファスナー21とを含み、各一次ファスナー6,7は、垂直片をコンクリート躯体Cwの前面Scに固定し、片面二次ファスナー10は外壁の下端又は上端で、両面二次ファスナー21は外壁の上下のパネル接続部d4で、断熱複合パネルP端面のセメント板の条溝aに突出片12a,12bを介して係止すると共に、各二次ファスナー10,21の水平片10F,10F´,21Fを各一次ファスナー6,7の水平片6F,7Fに前後左右位置調整して止着し、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を閉塞して空気流通を阻止すると共に、該パネルP内の条溝a群の外壁下端から上端までの空気流通Afを保証したものである。 For example, as shown in FIG. 2, the present invention shows an adhesive layer type heat insulating composite panel P in which a cement plate Pa and a heat insulating layer Pb are arranged on the inner surface in parallel with the grooves a in the vertical direction, and FIG. 3. As shown in FIG. 5, a single-sided secondary fastener 10 and a double-sided fastener 10 having projecting pieces 12a on one side of each horizontal piece form as shown in FIG. Each of the primary fasteners 6 and 7 has a vertical piece fixed to the front surface Sc of the concrete frame Cw, and the single-sided secondary fastener 10 has a lower end or an upper end of the outer wall. The double-sided secondary fastener 21 is an upper and lower panel connecting portion d4 on the outer wall, and is engaged with the groove a of the cement board on the end surface of the heat insulating composite panel P via the protruding pieces 12a and 12b. 2 The horizontal plate 10F, 10F', lateral position adjusted by fastened longitudinal horizontal plate 6F, the 7F of each primary fastener 6,7 to 21F, closing the interface gap as between the panel insulation layer Pb and concrete building frame front Sc Thus, air flow is prevented and air flow Af from the lower end to the upper end of the outer wall of the groove a group in the panel P is guaranteed.

尚、本発明でコンクリート躯体Cwとは、コンクリート基礎からパラペットまでを含むものである。
また、本発明にあっては、コンクリート躯体Cw前面Scに垂直片で強固に固定した一次ファスナー6,7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10,21を前後位置も、左右位置も調整して一次ファスナー6,7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とは当接形態とするが、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。
In the present invention, the concrete frame Cw includes a concrete foundation to a parapet.
Moreover, in this invention, with respect to the primary fasteners 6 and 7 firmly fixed to the concrete housing Cw front surface Sc with the vertical piece, the heat insulating composite panel P is attached to the secondary fastener 10 so that the outer wall front surface is flush. , 21 is adjusted to both the front and rear positions and the left and right positions to be fixed to the primary fasteners 6 and 7, so that the maximum projecting portion of the front surface Sc of the concrete body and the heat insulating layer Pb of the panel P are brought into contact with each other. An interface gap as corresponding to the unevenness of the front surface Sc is generated between the inner surface (heat insulating layer) of each panel P and the concrete housing surface Sc.

しかし、界面隙間asに対しては、図10(A),(B)の如く、上下のパネル断熱層Pb間への現場発泡断熱材9の注入による閉塞によっても、図9(A),(B)の如く、パネル下端面でのシーリング19及び隙間追従シート23による閉塞によっても、図11(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による閉塞によっても空気流通阻止が達成されるが、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を閉塞するだけでも良い。
また、各二次ファスナー10,21の一次ファスナー6,7への前後左右位置調整の下での止着は、二次ファスナー10,21を一次ファスナー6,7の水平片上への、摺動形態での載置とするため、前後左右調整が容易であり、一次ファスナーと二次ファスナーの止着は、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, as shown in FIGS. 10A and 10B, the interface gap as is also blocked by injection of the in-situ foam heat insulating material 9 between the upper and lower panel heat insulating layers Pb, as shown in FIGS. As shown in FIG. 11B, the air flow is also caused by the sealing 19 and the gap following sheet 23 at the lower end surface of the panel, or by the asphalt roof coating 9c on the upper end surface of the panel as shown in FIGS. Although the prevention is achieved, the air flow prevention of the interface gap as may be merely closing the interface gap as at the upper end or the lower end of the panel P.
Further, the fastening of the secondary fasteners 10 and 21 to the primary fasteners 6 and 7 under the front / rear left / right position adjustment is performed by sliding the secondary fasteners 10 and 21 onto the horizontal pieces of the primary fasteners 6 and 7. Therefore, it is easy to adjust the front and rear, right and left, and the fastening of the primary fastener and the secondary fastener can be performed by using conventional bolt fastening, screw fastening, welding, or the like.

また、二次ファスナー10,21のパネルP上端及び下端の条溝aへの係止は、図10(A)の如く、条溝a内へ嵌入適合した突出片12a,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12a,12bとの適切な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10,21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10,21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12a,12bとをねじ締着すれば良い。
Further, the upper and lower ends of the panel P of the secondary fasteners 10 and 21 are locked to the groove a, as shown in FIG. 10A, the protruding pieces 12a and 12b fitted and fitted into the groove a are attached to the outer surface of the cement plate Pa. The panel P may be secured to the secondary fasteners 10 and 21 by setting appropriate cross-sectional shapes of the groove a and the fitting protrusions 12a and 12b.
Of course, when rattling occurs between the panel P and the secondary fasteners 10 and 21 in the locked state, the cement plate Pa and the secondary fastener protruding pieces 12a and 12b may be screwed together.

また、本発明にあっては、断熱複合パネルPは、図2の如く、セメント板Paが少なくとも両側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10,21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10,21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10,21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の面一化調整作業も容易となる。
Further, in the present invention, as shown in FIG. 2, the heat insulating composite panel P includes a group of vertical grooves a1 and a2 including cemented plates Pa including a trapezoidal groove a1 at least at both side ends, and a heat insulating layer Pb. However, it is preferable that the molded foam heat insulating material is laminated and integrated on the surface of each groove a1, a2.
The trapezoidal section a1 having the trapezoidal cross section can achieve the locking of the panel P by the secondary fasteners 10 and 21 only by inserting the protruding pieces 12b having the trapezoidal cross section of the secondary fasteners 10 and 21.
And since the latching holding | maintenance of the panel P by the secondary fasteners 10 and 21 becomes the right-and-left both ends of a panel, the equalization adjustment operation | work of each panel P becomes easy.

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2(A)に示す如く、上端及び内表面上部の全幅に亘って、切欠C1を一次ファスナーの水平片板厚に対応して配置し、且つ、該パネルP両端部では、該切欠C1上に、更に二次ファスナー止着用の切欠C2を配置するのが好ましい。   Further, in the present invention, the heat insulation layer Pb of the heat insulation composite panel P has a notch C1 having a horizontal plate thickness of the primary fastener over the entire width of the upper end and the upper inner surface as shown in FIG. It is preferable that a notch C2 for fastening a secondary fastener is further disposed on the notch C1 at both ends of the panel P.

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、パネル断熱層Pb上端に配置する一次ファスナー7の水平片及び垂直片が断熱層Pbと面一に配置出来、図11(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での後処理等、切欠C1に対する補修作業が均斉、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10,21締着ボルトの突出部の受け入れも可能となり、図10(A)、図11(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、断熱層Pbの欠損が最少に抑制出来ると共に、作業性も向上する。
The provision of the notches C1 and C2 is easy in uniform operation as a work in another place such as a factory, and the horizontal piece and the vertical piece of the primary fastener 7 arranged at the upper end of the panel heat insulation layer Pb are the heat insulation layer Pb. As shown in FIG. 11 (B), the repair work for the notch C1 is uniform, such as post-processing with a plate material 18 such as an asbestos-cement board for the notch C1 of the heat insulating layer Pb when the outer wall upper part is constructed, and Easy to implement.
Further, the presence of the deep partial cutout C2 allows the protrusion of the secondary fastener 10, 21 fastening bolt to be received. As shown in FIGS. 10 (A) and 11 (A), the universal nut 8 protruding on the lower surface. The primary fastener 7 provided with the heat insulating composite panel P can be arranged smoothly on the heat insulating composite panel P, the loss of the heat insulating layer Pb can be minimized, and the workability can be improved.

また、本発明にあっては、一次ファスナー6,7は、図3(A),(B)に示す如く、各水平片6F,7Fに長孔H6,H7を、垂直片6W,7Wにボルト挿入用孔H60,H70を有するアングル鋼材であって、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6W,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H60,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。   In the present invention, as shown in FIGS. 3A and 3B, the primary fasteners 6 and 7 have long holes H6 and H7 in the horizontal pieces 6F and 7F and bolts in the vertical pieces 6W and 7W. An angle steel material having insertion holes H60 and H70, and a bolt insertion hole H60 having a diameter larger than the diameter of the anchor bolt 7a disposed on the vertical pieces 6W and 7W with respect to the anchor bolt 7a driven into the concrete housing front surface Sc. , H70 is preferably bolted to the anchor bolt 7a under position adjustment via H70.

この場合、アンカーボルト7aは、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を打込んでも良い。
従って、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適用出来る実用性の高い発明である。
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.
Therefore, the present invention is a highly practical invention that can be applied to a new construction of a concrete building as well as an external insulation modification of an existing concrete building.

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。
そして、垂直片7Wのボルト挿入用孔H70は径が20mm位として、アンカーボルト径10mmより大とするため、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のボルト締着は、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.
Since the bolt insertion hole H70 of the vertical piece 7W has a diameter of about 20 mm and is larger than the anchor bolt diameter of 10 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, bolt fastening of the vertical piece 7W to the anchor bolt 7a exhibits sufficient support strength of the secondary fastener 10.
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、中間一次ファスナー7の水平片7Fが、図3(B)、図4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内には、ナット8Aを固定した座金8Bを摺動自在、且つ、共回り不能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4の如く、平面長方形の座金8Bが両側板8Sの規制を受けてナット8Aの共回りを抑制するため、中間一次ファスナー7に対する二次ファスナー10,21の位置調整の下でのボルト締着が可能となり、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上面には、図2(A)の切欠C2の如き自在ナット金具8のみの凹欠を施すことにより、パネルPに対して、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 intermediate primary fastener 7 is provided with a free nut fitting 8 on the lower surface of the long hole H7 as shown in FIGS. The washer 8B, to which the nut 8A is fixed, is preferably slidable and cannot be rotated together.
In this case, the slidable nut 8A, as shown in FIG. 4, has a flat rectangular washer 8B that is restricted by the side plates 8S and restrains the rotation of the nut 8A. Since the bolts can be tightened under the position adjustment 21 and the nut 8A is held in the universal nut fitting 8, a flexible nut fitting such as a notch C2 in FIG. By providing only 8 recesses, it is possible to attach the primary fastener 7 to the upper end of the panel P neatly with a small amount of heat insulation layer loss with respect to the panel P.

また、本発明にあっては、片面二次ファスナー10は、図5(A)の如く、長孔H10を有する水平片10Fの前端片面に断面台形の突出片12aを突出し、外壁下端、又は上端で、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12aを係止するのが好ましい。
片面二次ファスナー10は、外壁下端、又は外壁上端でのパネル端面を係止保持するものであるが、この場合、二次ファスナーの突出片12aは、セメント板条溝a1の断面形態と対応形態で係合し、且つ両者間にガタツキの生じない嵌合となるため、二次ファスナー10によるパネル下端、又は上端の係止が合理的に実施出来る。
そして、片面二次ファスナー10の長孔H10を一次ファスナー6,7の長孔H6,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. 5A, the single-sided secondary fastener 10 projects a trapezoidal protruding piece 12a having a trapezoidal cross section on one front end surface of a horizontal piece 10F having a long hole H10, and the lower end or upper end of the outer wall. Thus, it is preferable that the protruding piece 12a of the secondary fastener 10 is locked to the groove a1 having a trapezoidal cross section of the heat insulating composite panel P.
The single-sided secondary fastener 10 latches and holds the lower end of the outer wall or the panel end face at the upper end of the outer wall. In this case, the protruding piece 12a of the secondary fastener is a cross-sectional form and a corresponding form of the cement plate groove a1. Therefore, the lower end of the panel or the upper end of the panel can be reasonably implemented by the secondary fastener 10.
And if the long hole H10 of the single-sided secondary fastener 10 is provided in an intersecting form with the long holes H6 and H7 of the primary fasteners 6 and 7, bolt fastening under the positional adjustment between both fasteners can be carried out rationally. .

また、本発明にあっては、両面二次ファスナー21は、図5(B)に示す如く、長孔H21を有する水平片21Fの前端上下面に断面台形の突出片12a,12bを突出し、上下パネル間に配置して、上方及び下方の断熱複合パネルPの断面台形の条溝a1に上下面の突出片12a,12bを係止するのが好ましい。
両面二次ファスナー21は、下方の突出片12aを下方パネル上端のセメント板条溝a1に係止して一次ファスナー7に止着後、上方パネル下端を上方の突出片12bに係合すれば、図10(A)の如く、上下パネル接続部d4での、上下両パネルの断面台形条溝a1と、断面台形突出片12a,12bとにより、ガタツキの生じない係止保持が出来る。
Further, in the present invention, as shown in FIG. 5B, the double-sided secondary fastener 21 projects the trapezoidal protruding pieces 12a and 12b having a trapezoidal cross section on the top and bottom surfaces of the horizontal piece 21F having the long holes H21. It is preferable that the upper and lower protruding pieces 12a and 12b are engaged with the upper and lower heat insulating composite panels P in the trapezoidal cross section a1 of the upper and lower surfaces.
When the double-sided secondary fastener 21 is engaged with the lower protruding piece 12a in the cement plate groove a1 at the upper end of the lower panel and fixed to the primary fastener 7, the lower end of the upper panel is engaged with the upper protruding piece 12b. As shown in FIG. 10 (A), the upper and lower panel connecting portions d4 can hold and hold the upper and lower panels with the trapezoidal grooves a1 and the trapezoidal projecting pieces 12a and 12b.

この場合、上方の突出片12bは、図5(B)に示す如く、水平片21F上に配置した目地用の台板21a上に突出配置するのが好ましい。
上方突出片12bが台板21上に存在すれば、上方パネルPのセメント板Paの下端は、図10(A),(B)の如く、リブR(図2)下端の台板21上への載置形態となり、二次ファスナー水平片21Fの厚さに関係なく、台板21によって接続部d4に所定の目地寸法が確保出来、接続部d4からの現場発泡断熱材9の所定の注入施工作業が容易となる。
In this case, as shown in FIG. 5B, the upper protruding piece 12b is preferably arranged so as to protrude on the joint base plate 21a arranged on the horizontal piece 21F.
If the upper protruding piece 12b exists on the base plate 21, the lower end of the cement plate Pa of the upper panel P is moved onto the base plate 21 at the lower end of the rib R (FIG. 2) as shown in FIGS. Regardless of the thickness of the secondary fastener horizontal piece 21F, the base plate 21 can secure a predetermined joint size at the connection part d4, and the predetermined injection construction of the in-situ foam insulation 9 from the connection part d4. Work becomes easy.

また、本発明にあっては、各一次ファスナー6,7が、図3(A),(B)の如く、水平片6F,7Fに前後方向の長孔H6,H7を備え、各二次ファスナー10,21が、図5(A),(B)の如く、水平片10F,21Fに左右方向の長孔H10,H21を備え、前後方向長孔H6,H7と左右方向長孔H10,H21を介して二次ファスナー10,21を一次ファスナー6,7上に位置調整してボルト締着するのが好ましい。
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。
In the present invention, as shown in FIGS. 3 (A) and 3 (B), the primary fasteners 6 and 7 are provided with the long holes H6 and H7 in the front-rear direction in the horizontal pieces 6F and 7F, respectively. As shown in FIGS. 5A and 5B, the horizontal pieces 10F and 21F have left and right long holes H10 and H21, and the front and rear direction long holes H6 and H7 and the left and right direction long holes H10 and H21 are provided. The secondary fasteners 10 and 21 are preferably positioned on the primary fasteners 6 and 7 and fastened with bolts.
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.

そして、各一次ファスナー6,7のそれぞれは、必ず垂直片6W,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10,21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10,21は、片面の突出片12aか、両面の突出片12a,12bを備えているため、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6,7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10,21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の面一化配置作業は、作業性からも、不陸対応の前後位置調整の後に、必要量の左右位置微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化配置が合理的に実施出来る。
Each of the primary fasteners 6 and 7 is required to keep the vertical pieces 6W and 7W in contact with and fixed to the concrete frame surface Sc for strength maintenance. Each of the fasteners 10 and 21 requires different front and rear position adjustment amounts according to the flattening reference of the panel P.
And since the secondary fasteners 10 and 21 are provided with a single-sided protruding piece 12a or double-sided protruding pieces 12a and 12b, it is difficult to dispose a sufficiently long front and rear elongated hole. 7 can be arranged up to a considerably large hole, facilitating the measurement and arrangement of each of the secondary fasteners 10 and 21 for adjusting the longitudinal movement.
In view of workability, it is preferable to perform the necessary amount of fine adjustment of the left and right positions after the front and rear position adjustment corresponding to the unevenness.
Therefore, it is possible to rationally implement the flattening arrangement under the firm fixation of the primary fastener 7 and the necessary forward / backward movement adjustment of the panel P.

また、本発明にあっては、図3(A),(B)に示す如く、各長孔H6,H7を左右に設けた各一次ファスナー6,7を、断熱複合パネルPの左右接続部d3(図12)に配置し、各長孔H6,H7に個々に対応した、各二次ファスナー10,21の2個を1個の一次ファスナー6,7上の左右に配置するのが好ましい。   Moreover, in this invention, as shown to FIG. 3 (A), (B), each primary fastener 6 and 7 which provided each long hole H6 and H7 on the left and right is connected to the right-and-left connection part d3 of the heat insulation composite panel P. It is preferable to arrange two secondary fasteners 10 and 21 on the left and right on one primary fastener 6 and 7, respectively, which are arranged in (FIG. 12) and individually correspond to the long holes H6 and H7.

この場合、1個の二次ファスナー10,21が、1枚のパネルPの一端部毎の対応となるため、一次ファスナー上への二次ファスナーの位置決めの自由度が増し、パネルP毎の面一化調整が容易となると共に、各パネルPの二次ファスナー上への載置係合作業も容易となる。
しかも、外壁上端部にあっては、図11(A)、図12(A)の如く、中間一次ファスナー7上に載置止着した各片面二次ファスナー10間で、笠木3係止用のブラケット4を一次ファスナー水平片7Fにねじ26aによって固定出来、ブラケット4の所定位置への取付作業も容易となる。
In this case, since one secondary fastener 10, 21 corresponds to one end of one panel P, the degree of freedom in positioning the secondary fastener on the primary fastener is increased, and the surface of each panel P is increased. The unification adjustment becomes easy, and the placement engagement work of each panel P on the secondary fastener becomes easy.
Moreover, at the upper end of the outer wall, as shown in FIGS. 11 (A) and 12 (A), the caps 3 are locked between the single-sided secondary fasteners 10 placed and secured on the intermediate primary fastener 7. The bracket 4 can be fixed to the primary fastener horizontal piece 7F by the screw 26a, and the work of attaching the bracket 4 to a predetermined position is facilitated.

また、図9(A)に示す如く、外壁下端では、下端一次ファスナー6の水平片6F上面と、断熱複合パネルPの断熱層Pb下面との隙間G1に、隙間追従シート23をコンクリート躯体前面Scに当接形態で配置するのが好ましい。
この場合、隙間追従シート23は、該隙間G1を空密的に閉止出来るものであれば良く、典型的には、断熱性、機密性、防湿性、非吸水性に優れた、幅20mm、厚さ2mmのポリエチレン製形状回復発泡体のソフトロン(積水化学(株)商品名)である。
Further, as shown in FIG. 9A, at the lower end of the outer wall, the gap follower sheet 23 is placed in the gap G1 between the upper surface of the horizontal piece 6F of the lower primary fastener 6 and the lower surface of the heat insulating layer Pb of the heat insulating composite panel P. It is preferable to arrange in a contact form.
In this case, the gap follow-up sheet 23 is only required to be able to close the gap G1 in an airtight manner. Typically, the gap follow sheet 23 is excellent in heat insulation, confidentiality, moisture resistance, and non-water absorption, width 20 mm, thickness This is Softron (trade name of Sekisui Chemical Co., Ltd.), a 2 mm thick polyethylene shape recovery foam.

該ソフトロンは、張着後1日経過でシートが発泡し、下端一次ファスナー6、断熱層Pb下端、及びコンクリート躯体前面Scに当接充填形態で隙間を閉止する。
従って、図9(B)の如く、下端一次ファスナー6の存在しない部所でも、パネル断熱層Pb下端とコンクリート躯体前面Sc間の界面隙間asにシーリング19を施せば、シーリング19と隙間追従シート23とによって、断熱複合パネルPの断熱層Pbとコンクリート躯体Cw間に例え界面隙間asが生じても、外壁下端で完全に閉塞出来、該界面隙間asは、密閉空気層となって空気断熱層としての断熱性を発揮する。
In the softlon, the sheet foams after one day from the tensioning, and closes the gap in a contact and filling manner with the lower primary fastener 6, the heat insulation layer Pb lower end, and the concrete housing front surface Sc.
Accordingly, as shown in FIG. 9B, if the sealing 19 is applied to the interface gap as between the lower end of the panel heat insulating layer Pb and the concrete housing front surface Sc even in a portion where the lower end primary fastener 6 does not exist, the sealing 19 and the gap following sheet 23 are provided. Even if an interface gap as is generated between the heat insulating layer Pb of the heat insulating composite panel P and the concrete frame Cw, it can be completely closed at the lower end of the outer wall, and the interface gap as becomes a sealed air layer as an air heat insulating layer. Demonstrate heat insulation.

また、パネルPの上下接続部d4では、図10の如く、上下パネルの、断熱層Pb間には条溝aを閉止しないように、現場発泡断熱材9を充填すると共に、セメント板Pa間には、シーリング19を付与するのが好ましい。
この場合、吹付工具としてディスペンサー(日本ヒルティ(株)商品名)に一液性ポリウレタンのフォーム管(容量:750ml)をアダプターを介して取付け、ディスペンサーの吐出調整ノブの調整の下に接続部d4の空隙からウレタンを吐出すれば、セメント板条溝aを閉塞することなく、断熱層Pb間スペースへの適量のウレタン注入が可能である。
そして、接続部d4の内部でのウレタン充填と前部でのシーリング19とにより、接続部d4での断熱機能低下は抑制出来る。
In addition, in the upper and lower connection part d4 of the panel P, as shown in FIG. 10, the in-situ foam heat insulating material 9 is filled so as not to close the groove a between the heat insulating layers Pb of the upper and lower panels, and between the cement plates Pa. Is preferably provided with a sealing 19.
In this case, a one-component polyurethane foam tube (capacity: 750 ml) is attached to the dispenser (Nippon Hilti Co., Ltd.) as a spraying tool via an adapter, and the connection part d4 is adjusted under the adjustment of the dispenser adjustment knob of the dispenser. If urethane is discharged from the gap, an appropriate amount of urethane can be injected into the space between the heat insulating layers Pb without closing the cement plate groove a.
And the heat insulation function fall in the connection part d4 can be suppressed by the urethane filling inside the connection part d4, and the sealing 19 in the front part.

また、本発明にあっては、図9に示す如く、外壁下端では、底板2Dに空気孔H2を備えた腰水切2を、前部上方は前部取付板15を介して二次ファスナー下面に止着し、後部は底板2D後端を後部取付板16を介して一次ファスナー垂直片6Wに止着し、空気孔H2からセメント板条溝a内へ空気流入可能とするのが好ましい。
腰水切2は、前部と後部の2点支持で強固に保持出来ると共に、後部取付板16と底板の止着位置選定により、二次ファスナー10の前後位置調整に伴うパネル下端の前後位置調整にも適切に追従出来、均斉な外観を呈する取付けとなる。
In the present invention, as shown in FIG. 9, the lower end of the outer wall has a waist drainer 2 provided with air holes H2 in the bottom plate 2D, and the front upper portion is connected to the lower surface of the secondary fastener via the front mounting plate 15. It is preferably fastened, and the rear part of the bottom plate 2D is fastened to the primary fastener vertical piece 6W via the rear mounting plate 16 so that air can flow into the cement plate groove a from the air hole H2.
The waist drainer 2 can be firmly held by supporting the front and rear two points, and by adjusting the position of the rear mounting plate 16 and the bottom plate, it is possible to adjust the front / rear position of the lower end of the panel accompanying the front / rear position adjustment of the secondary fastener 10. Can follow up properly, and it has a uniform appearance.

この場合、図9(A)の如く、腰水切底板2Dと後部取付板16とを、アングル形態の化粧板17を挟着して止着すれば、腰水切立下り板2Wと化粧板17の垂直片17Wとの間隔寸法Wbが一定になるように止着出来、且つ、化粧板17が一次ファスナー6の垂直片6W下端を隠蔽出来るため、腰水切2下端の均斉、且つ、きれいな仕上げに有利である。
更に、化粧板垂直片17Wとコンクリート躯体前面Scとの間にシーリング19を付与することにより、腰水切2内部への空気の流出入は、底板2Dの空気孔H2とセメント板条溝aのみとなり、断熱複合パネルP内への空気孔H2からの上昇空気流がスムーズに発生する。
In this case, as shown in FIG. 9 (A), if the waist water draining bottom plate 2D and the rear mounting plate 16 are fastened by sandwiching the decorative plate 17 in the form of an angle, the waist water vertical falling plate 2W and the decorative plate 17 Since the distance Wb between the vertical piece 17W can be fixed and the decorative plate 17 can conceal the lower end of the vertical piece 6W of the primary fastener 6, it is advantageous for uniform and clean finishing of the lower end of the lower drainage 2 It is.
Further, by providing a sealing 19 between the decorative plate vertical piece 17W and the concrete housing front surface Sc, the air flows into and out of the waist drainer 2 only by the air holes H2 of the bottom plate 2D and the cement plate groove a. The rising air flow from the air hole H2 into the heat insulating composite panel P is smoothly generated.

また、本発明にあっては、外壁上端では、図11に示す如く、アングル形態の笠木3の前部を、パネルPの上端部に止着したブラケット4で係止し、該笠木3の後部をコンクリート躯体上端面Fcに止着し、コンクリート躯体上端面の防水層9a前端からパネル上端面に亘ってルーフコーティング9cを配置するのが好ましい。
ルーフコーティング9cは、典型的にはアスファルトであり、ルーフコーティング9cは屋上防水層9aの端末処理と共に、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も閉塞し、コンクリート躯体前面Scに対する断熱層Pbの断熱機能低下を防止する。
In the present invention, at the upper end of the outer wall, as shown in FIG. 11, the front portion of the angle-shaped headboard 3 is locked by the bracket 4 fixed to the upper end portion of the panel P, and the rear portion of the headboard 3 Is fixed to the concrete casing upper end face Fc, and the roof coating 9c is preferably arranged from the front end of the waterproof layer 9a on the concrete casing upper end to the panel upper end.
The roof coating 9c is typically asphalt, and the roof coating 9c closes the interfacial gap as between the concrete housing front surface Sc and the panel heat insulating layer Pb together with the end treatment of the roof waterproof layer 9a, and insulates the concrete housing front surface Sc. Prevents a decrease in the heat insulation function of the layer Pb.

また、本発明にあっては、断熱複合パネルPの左右接続部d3では、図12に示す如く、断熱層Pb相互の当接界面Bbをセメント板Pa面上とし、セメント板Pa間の接続部d3間隔に目地シーリングするのが好ましい。
この場合、図2(B)に示す如く、セメント板Paの幅W0(490mm)より断熱層Pbの幅W1(500mm)を目地幅となる分だけ大とし、セメント板Paと断熱層Pbとを、断熱層Pbが一側縁PLではd1(10mm)入り込み、他側縁PRではd2(20mm)突出する形態に層着しておけば、左右パネルの断熱層Pbを衝合当接するだけで、図12(C)の如く、接続部d3では、断熱層Pbの当接界面Bbがセメント板PaのリブR1面上となり、両側のセメント板Pa間には、d2(20mm)−d1(10mm)の目地d3(10mm)が形成出来る。
In the present invention, in the left and right connection part d3 of the heat insulating composite panel P, as shown in FIG. 12, the contact interface Bb between the heat insulating layers Pb is on the cement board Pa surface, and the connection part between the cement boards Pa is provided. It is preferable to perform joint sealing at intervals of d3.
In this case, as shown in FIG. 2 (B), the width W1 (500 mm) of the heat insulating layer Pb is made larger than the width W0 (490 mm) of the cement plate Pa by an amount corresponding to the joint width, and the cement plate Pa and the heat insulating layer Pb are made. If the heat-insulating layer Pb is layered in a form that protrudes d1 (10 mm) at the one side edge PL and protrudes d2 (20 mm) at the other side edge PR, the heat-insulating layer Pb of the left and right panels only abuts against each other. As shown in FIG. 12C, in the connection part d3, the contact interface Bb of the heat insulating layer Pb is on the rib R1 surface of the cement plate Pa, and d2 (20 mm) −d1 (10 mm) between the cement plates Pa on both sides. The joint d3 (10 mm) can be formed.

そして、目地d3には、慣用のシーリング19を施すことにより外部空気の断熱層Pb上への侵入が阻止出来、例え、目地d3から断熱層Pb面上に空気が侵入しても、断熱層Pbの当接界面Bbへの到達が抑制出来、外部空気の当接界面Bbを経由したコンクリート躯体表面Scへの侵入が防止出来る。
従って、パネルPの左右接続部d3でのパネル断熱層Pbのコンクリート躯体前面Scに対する断熱機能低下は阻止出来る。
Then, by applying a conventional sealing 19 to the joint d3, it is possible to prevent external air from entering the heat insulating layer Pb. For example, even if air enters the surface of the heat insulating layer Pb from the joint d3, the heat insulating layer Pb Can be prevented from reaching the abutment interface Bb, and can be prevented from entering the concrete housing surface Sc via the abutment interface Bb of external air.
Therefore, the heat insulation function decline with respect to the concrete housing front surface Sc of the panel heat insulation layer Pb in the right-and-left connection part d3 of the panel P can be prevented.

本発明は、コンクリート躯体前面Scに張設する断熱複合パネルPが二次ファスナー10,21に係止され、且つ、各二次ファスナー10,21が、コンクリート躯体前面Scに固定した各一次ファスナー6,7に対して前後左右の位置調整の下に止着出来るため、コンクリート躯体前面Scの不陸の有無に関わりなく、接続並設する各断熱複合パネルP群の外面、即ち、各セメント板Pa表面、の面一で均斉な取付けが可能となる。   In the present invention, the heat insulating composite panel P stretched on the concrete housing front surface Sc is locked to the secondary fasteners 10 and 21, and each secondary fastener 10 and 21 is fixed to the concrete housing front surface Sc. , 7 can be fixed under the front / rear / right / left position adjustment, so that the outer surface of each heat-insulating composite panel P connected in parallel, ie, each cement plate Pa, regardless of whether or not the concrete body front surface Sc is uneven. The surface can be installed evenly and evenly.

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も、空気流通を阻止したために、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。
そして、一次ファスナー6,7は、コンクリート躯体Cwへのアンカーボルト7aによる強固な固定であれば良いため、アンカーボルト7aは、コンクリート躯体構築時の埋設でも、既存コンクリート躯体Cwへのあと施工での打込みでも可能であり、本発明は、新築建物にも、既存建物の乾式被覆改修外断熱構工法にも好適に適用出来る。
In addition, since the interfacial gap as generated between the panel heat insulating layer Pb and the concrete housing surface Sc generated by stretching the panels P to be flush with each other, the air layer in the gap as is circulated. The air-insulating layer functions as an unsealed air layer, and has an outer heat-insulating function for the concrete frame Cw together with the panel heat-insulating layer Pb.
Since the primary fasteners 6 and 7 need only be firmly fixed to the concrete frame Cw by the anchor bolts 7a, the anchor bolts 7a can be embedded in the concrete frame Cw even after being applied to the existing concrete frame Cw. The present invention can also be applied to a newly built building and a dry insulation / exterior heat insulation construction method for an existing building.

更に、断熱複合パネルPは、密着層型でありながら条溝a群を介したパネルP内の空気流通Afを保証したため、セメント板Paと断熱層Pbとの界面が条溝a群によって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て、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 in the panel P through the groove a group even though it is an adhesion layer type, the interface between the cement board Pa and the heat insulating layer Pb is viewed from below by the groove a group. It becomes an upper air-permeable layer and can solve the problem of dew condensation at the interface between the exterior material such as a cement board and the heat insulating layer, which is peculiar to the conventional adhesive layer type 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 groove 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 uniform outer heat insulating function and durability over a long period of time.

更に、コンクリート躯体前面Scに当接固定した各一次ファスナー6,7に対して、各二次ファスナー10,21を前後左右位置調整して止着し、各二次ファスナー10,21の突出片12a,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を二次ファスナーに係合するため、各パネルPの位置調整の下で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コンクリート躯体Cwの前面Scの不陸に関わりなく容易に実施出来る。   Further, the secondary fasteners 10 and 21 are fixed to the primary fasteners 6 and 7 abutted and fixed to the concrete housing front surface Sc by adjusting the front and rear, left and right positions, and fixed to the protruding pieces 12a of the secondary fasteners 10 and 21. , 12b, the heat insulating composite panel P is engaged with the secondary fastener by the engagement of the cement plate Pa with the groove a, so that the tensioning operation under the position adjustment of each panel P is easy. It is possible to easily perform the grouping arrangement work of the group regardless of the unevenness of the front surface Sc of the concrete frame Cw.

また、各一次ファスナー6,7は、アングル形態の鋼材の垂直片6W,7Wの大径のボルト挿入用孔H60,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6,7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の前後左右方向不陸のみならず、上下方向不陸にも対処可能となる。
従って、本発明は、コンクリート躯体前面Sc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。
The primary fasteners 6 and 7 are firmly joined by fitting the large-diameter bolt insertion holes H60 and H70 of the vertical pieces 6W and 7W of angle-shaped steel materials to the small-diameter anchor bolts driven into the concrete frame Cw. The primary fasteners 6 and 7 can be fixed to the surface Sc of the concrete housing Cw under vertical and horizontal position adjustments, and the panel P can be stretched not only in the front-rear and right-and-left direction of the concrete housing Cw. It is possible to cope with unevenness in the vertical direction.

Further, since the intermediate primary fastener 7 has a universal nut fitting 8 that slidably holds a washer 8B having a nut 8A fixed to the lower surface of the horizontal piece 7F, each secondary fastener 10, 21 on the intermediate primary fastener 7 is provided. This position adjustment slide becomes the slide of the washer 8B in the universal nut fitting 8 of the bolt 13a in the temporarily fixed state, and the fine adjustment slide can be smoothly performed without damaging the heat insulating layer Pb.
In addition, each secondary fastener 10, 21 has a trapezoidal cross-sectional protrusion piece 12a, 12b fitted and locked in the trapezoidal section groove a1 of the panel cement plate Pa. It becomes easy to hold and hold the upper and lower ends of P.

また、各二次ファスナーの各一次ファスナー上での前後左右位置調整は、一次ファスナー6,7の前後方向長孔H6,H7と、二次ファスナー10,21の左右方向長孔H10,H21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の形成も、断熱層Pbの欠損の最少限の下に容易に出来る。   Further, the front / rear / left / right positions of the secondary fasteners on the primary fasteners are adjusted to the front / rear direction long holes H6 / H7 of the primary fasteners 6, 7 and the left / right direction long holes H10, H21 of the secondary fasteners 10, 21. Since the bolt 13a is inserted and temporarily fixed to the nut 8A in the universal nut fitting 8, it can be carried out smoothly without causing any trouble to the panel thermal insulation layer Pb, and on the thermal insulation layer Pb that houses the universal nut fitting 8 The notch C2 can also be a narrow notch corresponding to the width of the universal nut 8 from the inner surface of the heat insulating layer Pb, and the formation of the notch C2 can be easily made under the minimum of the defect of the heat insulating layer Pb.

また、1個の一次ファスナーに対して2個の二次ファスナー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4も、片面二次ファスナー10間で一次ファスナーに取付可能となり、ブラケット4の取付合理化と、ブラケット4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 two secondary fasteners are arranged in a divided form with respect to one primary fastener, the position of each panel P can be adjusted at the end, and the position of each panel P group can be adjusted under fine adjustment. Mounting work is easy, which is advantageous for proper panel placement.
In addition, the bracket 4 for locking the headboard 3 can also be attached to the primary fastener between the single-sided secondary fasteners 10, and it is possible to rationalize the mounting of the bracket 4 and to uniformly hold the headboard 3 by arranging the brackets 4 at equal intervals. .

〔外壁上部の構築(図1、図11)〕
外壁上端でのパネル取付けには、中間一次ファスナー7と片面二次ファスナー10とを用いる。
図11(A)に示す如く、アンカーボルト7aをコンクリート躯体Cwに打込み、下面に自在ナット金具8を備えた中間一次ファスナー7の垂直片7Wのボルト挿入用孔H70(孔径:20mm)を、外径10mmのアンカーボルト7aの突出部に嵌合し、中間一次ファスナー7の位置を微調整して径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。
[Construction of the upper part of the outer wall (FIGS. 1 and 11)]
The intermediate primary fastener 7 and the single-sided secondary fastener 10 are used for panel attachment at the upper end of the outer wall.
As shown in FIG. 11A, the anchor bolt 7a is driven into the concrete frame Cw, and the bolt insertion hole H70 (hole diameter: 20 mm) of the vertical piece 7W of the intermediate primary fastener 7 provided with the universal nut fastener 8 on the lower surface is removed. The nut 7c is firmly fastened through a washer 7b having a bolt hole with a diameter of 12 mm by finely adjusting the position of the intermediate primary fastener 7 by fitting to the protruding portion of the anchor bolt 7a with a diameter of 10 mm.

次いで、固定された中間一次ファスナー7の水平片7Fの一方の長孔H7上に、パネルP一側端の条溝a1に下方突出片12aを係止した片面二次ファスナー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、径10mmのボルト13aを、座金13bを介して中間一次ファスナー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、片面二次ファスナー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。   Next, the horizontal piece 10F of the single-sided secondary fastener 10 in which the downward projecting piece 12a is locked to the groove a1 on one side end of the panel P is placed on one elongated hole H7 of the horizontal piece 7F of the fixed intermediate primary fastener 7. Place the bolts H7 and H10 for bolt insertion of both fasteners 7 and 10, and insert a bolt 13a having a diameter of 10mm into a nut 8A in the universal nut 8 on the lower surface of the intermediate primary fastener 7 through a washer 13b. Then, after the position of the single-sided secondary fastener 10 is adjusted by the front / rear direction long hole H7 and the left / 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12(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. 12 (A), 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11(B)の如く、中間一次ファスナー水平片7F間の断熱層切欠C1には、該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11(A)、図12(A)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4の底板4D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4を各パネル間隔で配置する。
Then, as shown in FIG. 11B, an asbestos-cement board 18 (JISA5403 asbestos slate) having the same thickness as the primary fastener horizontal piece 7F is adhered to the heat insulation layer notch C1 between the intermediate primary fastener horizontal pieces 7F. Repair notch C1 on the upper surface of Pb.
Next, as shown in FIGS. 11 (A) and 12 (A), the bottom plate 4D of the bracket 4 is drilled at a predetermined position between the secondary fasteners 10 on both sides of the primary fastener horizontal piece 7F (Sanko Techno Co., Ltd.). The product is fastened to the primary fastener horizontal piece 7F with a screw 26a such as a product name), and the brackets 4 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11(A),(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、必要に応じて、セメント板Paを、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 housing upper end, as shown in FIGS. 11A and 11B, and the concrete housing front surface Sc and the panel. The interface gap as between the heat insulation layers 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, if necessary, the cement plate Pa is fixed to the face plate 12P of the secondary fastener protruding piece 12b by the screw 26.

次いで、笠木3は、図11(A)の如く、中間一次ファスナー水平片7F上に固定したブラケット4の水平片4U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。
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。
Next, as shown in FIG. 11A, 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 front end of the horizontal piece 4U of the bracket 4 fixed on the intermediate primary fastener horizontal piece 7F. Then, the rear part of the bottom plate 3D extending rearward is fixed to the concrete casing (parapet) Cw upper end face Fc from above the existing waterproof layer 9a with a screw 26b.
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.
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.

尚、図12に示す如く、外壁の下端から上端までの各断熱複合パネルPは、従来例1、2同様に上下方向中間で、且つ、両側端部適所をあと施工アンカー24でセメント板Paをコンクリート躯体Cwに打ち付ける。
この場合、各パネルPの左右両側面は、図2(B)の如く、セメント板Paに対して断熱層Pbが一側PLではd1(10mm)入り込み、他側PRではd2(20mm)突出しているため、パネル左右接続部d3では、図12(C)の如く、両側パネルの断熱層Pb当接界面Bbがセメント板Pa面で閉止出来、且つ、目地d3にバックアップ材19´を介してシーリング19を充填することにより、目地d3→断熱層Pb→コンクリート躯体への空気の流入が完全に防止出来、パネルPの接続部d3での断熱機能低下が抑制出来る。
In addition, as shown in FIG. 12, each heat insulation composite panel P from the lower end to the upper end of the outer wall is in the middle in the vertical direction as in the conventional examples 1 and 2, and the cement plate Pa is attached with the post-installed anchor 24 at appropriate positions on both side ends. It hits the concrete frame Cw.
In this case, as shown in FIG. 2 (B), the left and right side surfaces of each panel P protrude with d1 (10 mm) on the one side PL and d2 (20 mm) on the other side PR with respect to the cement board Pa. Therefore, at the panel left and right connection part d3, as shown in FIG. 12C, the heat insulating layer Pb contact interface Bb of both side panels can be closed on the cement plate Pa surface, and the joint d3 is sealed via the backup material 19 '. By filling 19, the inflow of air into the joint d3 → the heat insulating layer Pb → the concrete frame can be completely prevented, and the heat insulating function deterioration at the connecting portion d3 of the panel P can be suppressed.

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にあっては、パネルPの左右並列接続部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Pの上下の連結もパネル断熱層Pbとコンクリート躯体前面Scとの界面隙間asが、下端では隙間追従シート23及びシーリング19で、中間のパネル上下接続部d4では現場発泡断熱材9で、上端では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、断熱複合パネルPを張設した外壁は、下端の腰水切2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 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 at the cement plate Pa surface in the left and right parallel connection portion d3 of the panel P. As a result, air intrusion into the contact interface Bb is completely prevented, and a decrease in the heat insulation function at the connection part d3 can be prevented, and the upper and lower connections of the panel P are also performed at the interface gap as between the panel heat insulation layer Pb and the concrete housing front surface Sc. However, at the lower end, the gap follower sheet 23 and the sealing 19 are closed, and the middle panel upper and lower connection part d4 is closed with the in-situ foam heat insulating material 9, and the upper end is closed with the asphalt roof coating 9c. Therefore, the outer wall provided with the heat insulating composite panel P exhibits the outer heat insulating function as designed.
In the upper and lower connection part d4, air can flow from the lower panel groove a to the upper panel groove a. Therefore, the outer wall on which the heat insulating composite panel P is stretched is connected from the lower end drainage drainage 2 to the upper end headboard 3 The air flow Af to the outside via the is guaranteed.

また、各一次ファスナー6,7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コンクリート建築物に改修出来る。   Moreover, since each primary fastener 6 and 7 is all fixed to the front surface Sc of the concrete frame Cw, it can be firmly fixed by the anchor bolt 7a, and each panel P is based on the maximum uneven projection of the concrete frame front surface Sc. In the non-landic concave part of the concrete body surface Sc, the surface of the concrete body 15 m after construction is 1 m away from the surface of the concrete body, since it is stretched flush with the interface P between the panel P and the concrete body surface Sc. Even a concrete building with an unevenness of 10 mm or more can be repaired to a high-performance external heat insulating concrete building in which the outer wall surface, that is, the panel cement board Pa surface is cleanly aligned.

If the secondary fasteners 10 ′ and 21 ′ of the modified example are employed for renovation of a building having a low concrete surface Sc, the panel can be stretched with good workability.

また、上下パネル接続部d4で、界面隙間asが大きい場合は、両面二次ファスナー21への上方パネルPの係合載置に先立って、中間一次ファスナー7上、及び各中間一次ファスナー7間の断熱層Pb上に、隙間追従シート23やバックアップ材等を、コンクリート躯体前面Scに当接形態で配置しておけば、その後の現場発泡断熱材9の注入充填が合理的に実施出来る。
また、セメント板の条溝aを全て均一断面の矩形としておき、側端の二次ファスナー突出片を嵌入する条溝aにのみ、上下端でリブR間を鉄片で閉止すれば、嵌入係合用の二次ファスナーの突出片12a,12bも断面矩形と出来、セメントパネルPaの成形も、二次ファスナー10,21の突出片製作も合理化出来る。
Further, when the interface gap as is large at the upper and lower panel connecting portion d4, prior to the engagement mounting of the upper panel P on the double-sided secondary fastener 21, the intermediate primary fastener 7 and between the intermediate primary fasteners 7 If the gap following sheet 23, the backup material, etc. are arranged in contact with the concrete housing front surface Sc on the heat insulating layer Pb, the subsequent filling and filling of the in-situ foam heat insulating material 9 can be carried out rationally.
Moreover, if all the groove | channel a of a cement board is made into the rectangle of uniform cross section, and it closes between the ribs R with an iron piece only in the groove | channel a which inserts the secondary fastener protrusion piece of a side end, it is for insertion engagement. The protruding pieces 12a and 12b of the secondary fastener can also have a rectangular cross section, so that the molding of the cement panel Pa and the manufacturing of the protruding pieces of the secondary fasteners 10 and 21 can be rationalized.

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、コンクリート建物の新築に適用出来るが、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に、1mにつき10mm位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. The insulation composite panel P can be stretched on the surface and applied to new construction of concrete buildings. However, in the case of existing concrete buildings that have been built for more than 15 years, the outer surface of the concrete frame is about 10 mm per meter.
