JP 2004-76332 A

従来の腰水切取付構造(図5)は、鉄筋又は鉄骨コンクリート造外断熱建築物に於いて、腰水切から笠木までの通気層内での空気貫流を保証し、傾斜天板上からも、底板下面からも、雨水の外壁内への浸入が阻止出来る、機能上優れたものではあるが、断熱パネル下端のセメント板下面への、下方からの受金具の当接及び長孔による位置調整止着は、セメント板下面を損傷する危険があり、煩雑、且つ困難な作業であった。   The conventional water drainage mounting structure (Fig. 5) guarantees air flow in the ventilation layer from the water drainage to the headboard in the reinforced steel or steel-concrete external heat insulation building. Although it is excellent in terms of function, it can prevent rainwater from entering the outer wall from the bottom surface. Has a risk of damaging the lower surface of the cement plate, and is a complicated and difficult operation.

また、共同住宅などの建築物のように、地盤面と1階床面との段差が大きい場合は好適ではあるが、事務所、店舗等の地盤面と1階床面との段差が小さい建物にあっては、積雪によって通気機能が低下する危険があった。
また、腰水切の上部(傾斜天板上部)と下部(底板下面)にシーリングが存在するので、美観上の問題もあった。
本発明は、新規な、腰水切金具、及び腰水切取付金具を採用することにより、これら従来技術の問題を一挙に解決、又は改善することを可能とするものである。
Moreover, it is preferable when the level difference between the ground surface and the first floor is large, such as a building such as a housing complex, but a building where the level difference between the ground and the first floor is small. In that case, there was a risk that the ventilation function would deteriorate due to snow accumulation.
In addition, since there is a sealing at the upper part (upper side of the inclined top plate) and the lower part (lower surface of the bottom plate) of the waist drainage, there was also an aesthetic problem.
The present invention makes it possible to solve or improve these problems of the prior art at once by adopting a novel waist drainage fitting and waist drainage fitting.

本発明の、外断熱建築物に於ける腰水切取付構造は、例えば、図1に示す如く、外壁1が、断面台形の条溝AG´を含む通気用の条溝AG,AG´群を内面に並列縦設した成形セメント板2Aと、断熱層2Bとを層着した断熱パネル2を外面に備え、セメント板2Aの台形条溝AG´は、断面形状が、最内部の平坦背面AFと、両側の等角度で内方に拡開形態で傾斜した傾斜側面ASとを備えた、左右対称の前部が開口する台形であり、固定部16A、可動部16B、ねじボルト16C及びナット16Dで構成する取付金具16を、セメント板2Aの下端2Dから台形条溝AG´内に、且つ固定部16A下部がセメント板下端2Dから下方に突出した形態に嵌入し、取付金具16の固定部16Aを平坦背面AFにボルト16Cで当接し、可動部16Bをナット16Dによってボルト16C上を前方に移動し、両側縁のアンカー片16B´を台形条溝AG´の傾斜側面ASに当接固定し、アンカー板15Pを垂下した座板15B、を備えた腰水切15の斜辺15U後端の立上り辺15Aを、台形条溝AG´内から垂下した固定部16Aに固着したものである。
As shown in FIG. 1, for example, as shown in FIG. 1, the outer wall 1 has an aerial groove AG, AG ′ group including inner grooves AG ′ including trapezoidal grooves AG ′. Are provided with a heat-insulating panel 2 formed by laminating a molded cement plate 2A and a heat-insulating layer 2B, and the trapezoidal groove AG ′ of the cement plate 2A has a cross-sectional shape of an innermost flat back surface AF, It has a trapezoidal shape with a symmetrical front part that has an inclined side surface AS that is inclined inwardly at equal angles on both sides, and is composed of a fixed part 16A, a movable part 16B, a screw bolt 16C, and a nut 16D. The fitting 16 to be fitted is inserted into the trapezoidal groove AG ′ from the lower end 2D of the cement plate 2A, and the lower portion of the fixing portion 16A protrudes downward from the lower end 2D of the cement plate, and the fixing portion 16A of the mounting bracket 16 is flattened. Abutting the back AF with a bolt 16C, a movable part 6B moved on bolts 16C forward by the nut 16D, abut secure the anchor piece 16B' of both side edges on the inclined side surface AS of the trapezoidal groove AG', comprising a seat plate 15B, hanging down the anchor plate 15P The rising edge 15A at the rear end of the hypotenuse 15U of the waist drainer 15 is fixed to a fixing portion 16A hanging from the trapezoidal groove AG ′.

尚、条溝AG,AG´の形状、配置形態は、少なくとも取付金具16を挿入固着するための条溝AG´を適所に散在すれば良く、全条溝が均一の断面台形条溝AG´であっても良いが、典型的には、図2(B)に示す如く、1枚のパネル2の幅2Awが490mmのセメント板2Aにあって、条溝AG´を両側、及び中央部に、その他を断面矩形の条溝AGとして配置したものである。   In addition, the shape and arrangement of the grooves AG, AG ′ may be such that at least the grooves AG ′ for inserting and fixing the mounting bracket 16 are scattered in place, and all the grooves are trapezoidal grooves AG ′ having a uniform cross section. Typically, as shown in FIG. 2 (B), the width 2Aw of one panel 2 is in a cement plate 2A having a size of 490 mm, and the groove AG ′ is formed on both sides and the center portion. Others are arranged as a groove AG having a rectangular cross section.

そして、本発明の腰水切取付構造は、図(A)に示す如く、取付金具16がセメント板2Aの条溝AG´内で、且つ固定部16Aをセメント板条溝AG´内に当接した状態での固定であるため、各散在固定する取付金具16は、前後位置調整せずとも、セメント板2Aの外面に対して前後方向均斉位置となり、腰水切15は、単に取付金具16に固定するだけで、セメント板2A前面からの突出寸法が均斉に保持出来、また、取付金具16のセメント板2Aへの取付けも、単に条溝AG´内への嵌入と、ねじボルト16C及びナット16Dによる可動部16Bの条溝AG´への圧着固定であるため、単にボルト・ナット操作によって取付作業が容易であり、しかも、セメント板2Aを何ら損傷せずに取付けられる。   In the waist drainage mounting structure of the present invention, as shown in FIG. (A), the mounting bracket 16 is in contact with the groove AG ′ of the cement plate 2A, and the fixing portion 16A is in contact with the cement plate groove AG ′. Since the fixing brackets 16 that are scattered and fixed are not adjusted in the front-rear position, the mounting brackets 16 are fixed in the front-rear direction with respect to the outer surface of the cement plate 2A, and the waist drainer 15 is simply fixed to the mounting bracket 16. As a result, the projecting dimensions from the front surface of the cement plate 2A can be maintained uniformly, and the mounting bracket 16 can be mounted on the cement plate 2A simply by fitting it into the groove AG 'and moving it with the screw bolt 16C and nut 16D. Since the portion 16B is crimped and fixed to the groove AG ′, the mounting operation is easy by simply operating the bolts and nuts, and the cement plate 2A can be mounted without any damage.

また、可動部16B両側縁のアンカー片16B´は、傾斜側面ASに圧接するだけで止着出来れば良く、典型的には、傾斜側面ASと同一、若しくは近似の傾斜側面を備えたものである
そして、条溝AG´が左右対称台形であるため、ねじボルト16Cとナット16Dによって移動する可動部16Bのアンカー片16B´は、両側の傾斜側面ASへの均等圧着が可能となり、ナット16Dによる強力なねじ締着によっても、セメント板2Aの損壊は生じることなく、取付金具16のセメント板2Aへの取付作業がスムーズに実施出来る
また、腰水切15の座板15Bのアンカー板15Pは、図1(A)の如く、セメント板2Aの外面に外壁タイル13を張設した場合は、外壁タイル上端の目隠しとなり、外壁タイル13を採用しない場合は、セメント板2Aと座板15B下面とのシールを隠蔽する作用を奏する。
従って、本発明の腰水切取付構造は、セメント板2Aを何ら損傷することなく、簡単な作業で腰水切15をセメント板2Aに対して均斉に取付けることが出来、外観も、腰水切15の下面はアンカー板15Pによってきれいに隠蔽出来、機能美に富み、均斉な形態の腰水切構造が簡単な作業で提供出来る。
Further, the anchor pieces 16B ′ on both side edges of the movable portion 16B only need to be brought into contact with the inclined side surface AS and are typically provided with inclined side surfaces that are the same as or similar to the inclined side surface AS. .
And since groove AG 'is a right-and-left symmetrical trapezoid, anchor piece 16B' of movable part 16B which moves with screw bolt 16C and nut 16D becomes possible to carry out the equal pressure-bonding to the inclined side surface AS of both sides, and strong by nut 16D Even when the screws are fastened, the mounting of the mounting bracket 16 to the cement plate 2A can be carried out smoothly without damaging the cement plate 2A .
Further, as shown in FIG. 1A, the anchor plate 15P of the seat plate 15B of the waist drainer 15 becomes blindfolded at the upper end of the outer wall tile when the outer wall tile 13 is stretched on the outer surface of the cement plate 2A. When not employed, the seal between the cement plate 2A and the lower surface of the seat plate 15B is concealed.
Therefore, the waist drainage mounting structure of the present invention can attach the waist drainer 15 to the cement plate 2A uniformly by a simple operation without damaging the cement plate 2A. Can be concealed neatly by the anchor plate 15P, is rich in functional beauty, and can provide a uniform form of waist drainage structure with a simple operation.

また、腰水切取付構造の発明にあっては、腰水切15は、断面形状が、後端の立上り辺15Aから前方への斜辺15Uと、斜辺15U前端からの立下り辺15Fと、立下り辺15F下端から水切り辺15Sを残して後方へ水平に延出する座板15Bとを有し、座板15Bが前端部に空気孔H15を、空気孔H15配置域の後部から垂下するアンカー板15Pを備えているのが好ましい。
この場合、腰水切15は、標準長4000mmとしておけば、目地幅を含めて標準幅500mmとなるセメント板2Aの割付けに好都合であり、空気孔H15は、座板15Bの剛性を損なわなければ良く、典型的には、図1(D)の如く、 細幅横長孔とし、50mm間隔で配置すれば良い。
Further, in the invention of the waist drainer mounting structure, the waist drainer 15 has a cross-sectional shape having a hypotenuse 15U forward from the rising edge 15A at the rear end, a falling edge 15F from the front end of the hypotenuse 15U, and a falling edge. 15F has a seat plate 15B extending horizontally rearward leaving a draining edge 15S, and the seat plate 15B has an air hole H15 at the front end and an anchor plate 15P hanging from the rear of the air hole H15 arrangement area. It is preferable to provide.
In this case, if the waist drainer 15 has a standard length of 4000 mm, it is convenient for the allocation of the cement plate 2A having a standard width of 500 mm including the joint width, and the air hole H15 may be used as long as the rigidity of the seat plate 15B is not impaired. Typically, as shown in FIG. 1 (D), narrow and long holes may be arranged at intervals of 50 mm.

そして、アンカー板15Pは、典型的には、水切り辺15Sより、16mm後方で15mm降下したものである。
従って、図1(A)の如く、セメント板2Aの外面に外壁タイル13を張設した際には、アンカー板15Pが腰水切15下面の外壁タイル13上端を挟持形態で隠蔽し、外壁タイル13を張設しない場合は、座板15Bとセメント板2A上端との隙間はシーリング充填となるが、アンカー板15Pは、セメント板2A上端のシーリングを隠蔽するため、アンカー板15Pを備えた腰水切15は、シーリングの露出が斜辺上部の1本のみとなり、アンカー板15Pが、腰水切下部で、すっきりした機能美を発揮し、外観の優れた腰水切取付構造となる。
The anchor plate 15P is typically lowered 15 mm behind the draining side 15S by 16 mm.
Therefore, as shown in FIG. 1 (A), when the outer wall tile 13 is stretched on the outer surface of the cement board 2A, the anchor plate 15P conceals the upper end of the outer wall tile 13 on the lower surface of the drainage drainage 15 in a sandwiched form, and the outer wall tile 13 Is not installed, the gap between the seat plate 15B and the upper end of the cement plate 2A is sealed, but the anchor plate 15P conceals the sealing at the upper end of the cement plate 2A. The seal is exposed only at the upper part of the hypotenuse, and the anchor plate 15P exhibits a clean functional beauty at the lower part of the waist drainage, resulting in a waist drainage mounting structure with an excellent appearance.

また、腰水切取付構造の発明にあっては、図1(A)に示す如く、外壁1の断熱パネル2のセメント板2Aのみに横断する開口部L6を切開し、該開口部L6に腰水切15を嵌合配置し、且つ腰水切座板15Bをセメント板上端2Tに、条溝AG,AG´を塞がないように載置するのが好ましい。
この場合、標準タイプの腰水切15にあっては、座板15Bの幅と斜辺15Uの幅とは同幅のW15であるため、斜辺15Uの後端の立上り辺15Aをセメント板条溝AG´内から垂下した固定部16Aに止着すれば、座板15Bの後端も、条溝AG´に掛らない状態でセメント板2A上端に着座出来る。
従って、建物設計によって、例えば、図4の如く、腰水切を積雪に配慮して地面GLよりかなり高い位置に配置することも可能であり、腰水切15の下面が見え易い位置での配置となっても、座板15Bから垂下するアンカー板15Pが下方セメント板2Aの上端2Tをきれいに隠蔽するため、腰水切15は、機能美に富む外観となる。
Further, in the invention of the waist drainage mounting structure, as shown in FIG. 1A, an opening L6 that crosses only the cement plate 2A of the heat insulating panel 2 of the outer wall 1 is cut open, and the waist drainage is cut into the opening L6. It is preferable that 15 is fitted and disposed, and the waist-water seat plate 15B is placed on the cement plate upper end 2T so as not to block the grooves AG and AG ′.
In this case, since the width of the seat plate 15B and the width of the hypotenuse 15U are the same width W15 in the standard type waist drainer 15, the rising edge 15A at the rear end of the hypotenuse 15U is used as the cement plate groove AG '. If fixed to the fixing portion 16A hanging from the inside, the rear end of the seat plate 15B can also be seated on the upper end of the cement plate 2A without being caught in the groove AG ′.
Therefore, depending on the building design, for example, as shown in FIG. 4, it is possible to place the waist drainer at a position considerably higher than the ground GL in consideration of snow accumulation, and the layout is such that the lower surface of the waist drainer 15 is easily visible. However, since the anchor plate 15P suspended from the seat plate 15B conceals the upper end 2T of the lower cement plate 2A, the waist drainer 15 has an appearance rich in functional beauty.

また、腰水切取付構造の発明にあっては、図1(A)の如く、セメント板2Aの外面に外壁タイル13を張設し、開口部L6の斜辺15U上の隙間は、バッカー14Bを介してシーリング14Aで閉止し、開口部L6の下部の外壁タイル13上端をアンカー板15Pで隠蔽するのが好ましい。
この場合、アンカー板15Pの垂下位置は、セメント板2Aの外面の外壁タイル13の外面に当接する寸法とすれば良い。
従って、腰水切の斜辺15U上部では、バッカー14Bの存在により、シーリング14Aが間隔をきれいに充填閉塞し、腰水切の座板15B下部では、アンカー板15Pが、外壁タイル13上端を、挟着形態できれいに被覆保護し、且つ、水切り辺15Sの存在によって、雨水の浸入の無い、空気arの貫流の可能な腰水切構造の、自由な高さ位置での配置が可能となる。
Moreover, in the invention of the waist drainage mounting structure, as shown in FIG. 1 (A), the outer wall tile 13 is stretched on the outer surface of the cement board 2A, and the gap on the hypotenuse 15U of the opening L6 passes through the backer 14B. It is preferable to close the upper end of the outer wall tile 13 below the opening L6 with an anchor plate 15P.
In this case, the hanging position of the anchor plate 15P may be set to a size that abuts on the outer surface of the outer wall tile 13 on the outer surface of the cement plate 2A.
Therefore, at the upper part of the hypotenuse 15U of the pelvic drainage, the sealing 14A is filled and closed due to the presence of the backers 14B, and at the lower part of the pelvic draining seat plate 15B, the anchor plate 15P and the upper end of the outer wall tile 13 are sandwiched. With the presence of the draining edge 15S, it is possible to arrange the waist drainage structure that allows the air ar to flow through without any intrusion of rain water and can be arranged at any height.

また、腰水切取付構造の発明に採用する取付金具は、図1(C)に示す如く、両側には圧着用の前辺16A”を、中央部にはねじ孔h16を有する突出板部16Fを両側の屈曲部16A´で形成した屈曲板状の固定部16Aと、中央にはボルト孔h16´を備え、両側縁には前方への拡開形態に突出する小幅Waのアンカー片16B´を備えた平板状の可動部16Bと、ねじボルト16Cと、ナット16Dとから成るものである。   Further, as shown in FIG. 1 (C), the mounting bracket employed in the invention of the waist drainage mounting structure has a crimping front side 16A "on both sides and a protruding plate part 16F having a screw hole h16 in the center. A bent plate-like fixing portion 16A formed by bent portions 16A ′ on both sides, a bolt hole h16 ′ at the center, and anchor pieces 16B ′ with a small width Wa projecting in a front-opening form on both sides. The plate-shaped movable portion 16B, a screw bolt 16C, and a nut 16D.

この場合、固定部16Aは、中央のねじ孔h16が突出部16Fに存在するため、ねじボルト16Cの螺入調整が可能となり、併せて突出部16Fが屈曲部16A´を介して前辺16A”に対する条溝AG´の背面AFへの弾性的押圧力付与が可能となって、条溝AG´内での完全な圧着力付与が可能となる。
また、可動部16Bは、ナット16Dの螺合回動によって、条溝AG´の傾斜(標準:60°)側面ASへの小幅Wa(標準:3mm)で同一傾斜角60°のアンカー片16B´による面圧着作用が発揮出来、ナット16Dの締着力によって、固定部16Aと可動部16Bによる条溝AG´内面に対する取付金具16の強固な、且つセメント板条溝AG´を損傷しない圧着保持が可能となる。
In this case, the fixing portion 16A has the central screw hole h16 in the protruding portion 16F, so that the screw bolt 16C can be screwed in, and the protruding portion 16F is also connected to the front side 16A "via the bent portion 16A '. Therefore, it is possible to apply an elastic pressing force to the back surface AF of the groove AG ′ with respect to the groove AG ′, and it is possible to apply a complete pressing force within the groove AG ′.
Further, the movable portion 16B has an anchor piece 16B ′ having a small width Wa (standard: 3 mm) to the side surface AS of the inclination (standard: 60 °) and the same inclination angle of 60 ° by screwing rotation of the nut 16D. The surface crimping action of the nut 16D can be exerted, and the fastening force of the nut 16D allows the fixing bracket 16 to be firmly attached to the inner surface of the groove AG 'by the fixed portion 16A and the movable portion 16B, and the crimping and holding without damaging the cement plate groove AG' is possible. It becomes.

また、取付金具の発明にあっては、図1(B)に示す如く、固定部16Aの長さL16が、セメント板条溝AG´の背面AFの長さL22より若干小であり、可動部16Bの長さL16´が、セメント板条溝AG´の開口部長さL22´より大で、固定部長さL16より小である。
この場合、条溝AG´の深さgdが13mm、背面AFの長さL22が44mm、開口幅L22´が30mmの標準セメント板2Aに用いる標準取付金具にあっては、固定部長さL16は40mm、固定部高さH16は35mm、可動部長さL16´は32mm、高さH16´は35mm、アンカー片16B´は3mm幅で60°傾斜したものであり、ねじボルト16Cは、径3mm、長さ10mmである。
Further, in the invention of the mounting bracket, as shown in FIG. 1 (B), the length L16 of the fixed portion 16A is slightly smaller than the length L22 of the back surface AF of the cement plate groove AG ′, and the movable portion The length L16 ′ of 16B is larger than the opening length L22 ′ of the cement plate groove AG ′ and smaller than the fixed portion length L16.
In this case, in the standard mounting bracket used for the standard cement plate 2A in which the depth gd of the groove AG ′ is 13 mm, the back face AF length L22 is 44 mm, and the opening width L22 ′ is 30 mm, the fixing portion length L16 is 40 mm.
