Description

本発明は、押出成形セメント板を用いて建物の外壁に外装仕上材を取り付ける外装仕上材の取付構造に関し、特に、外装仕上材を、簡素な構造で高強度かつ容易に取付けできるようにした改良技術に関する。   The present invention relates to an exterior finishing material mounting structure in which an exterior finishing material is attached to an outer wall of a building using an extrusion-molded cement board, and in particular, an improvement in which the exterior finishing material can be attached with high strength and easily with a simple structure. Regarding technology.

従来より、押出成形セメント板を外壁として建物躯体に取り付け、表面に各種外装仕上材を取り付けることが行なわれている。押出成形セメント板への仕上げとしては、塗装、タイル張り、石張りなどが行なわれている。押出成形セメント板は、中空で断面形状を自由にできることから、押出成形セメント板の表面に溝を設けて石やタイルなどの外装仕上材を引っ掛けて取り付けたり、中空部を利用して仕上材を留め付けたりすることも行なわれている。   Conventionally, an extrusion-molded cement board is attached to a building frame as an outer wall, and various exterior finishing materials are attached to the surface. Painting, tiles, stones, etc. are used to finish extrusion cement boards. Extruded cement board is hollow and can be freely shaped in cross section, so a groove is provided on the surface of the extruded cement board to attach exterior finishing materials such as stones and tiles, or the finishing material can be applied using the hollow part. They are also fastened.

例えば特許文献1には、溝を表面に設けた押出成形セメント板にセラミックタイル(外装仕上材)を引っ掛け、金具で留め付ける複合建材が開示されている。図7に示すように、押出成形セメント板1は片面蟻溝の凹部3を有し、この凹部3は一方の側壁は蟻溝5の形状であり、他方の側壁は垂直で、その側壁にはその外側端部に突起部7を有し、これにより側壁には該突起部7で囲まれた側壁凹部9がセメント板1の奥行きに沿って形成されている。凹部3にセラミックタイル11の裏面に形成された凸部13を嵌合する。ついでセメント板1とセラミックタイル11の間の空間に取付け金具15を配置する。この取付け金具15は、取付け金具の内側にはスプリングコイル型のバネ17が付設されている。このバネ17の自由端は、セメント板1の凹部3の側壁凹部9に嵌合され、突起部7により揺動が防止される。また金具15の他方の端部は、セラミックタイル11の上端に引っかけて係合している。   For example, Patent Document 1 discloses a composite building material in which a ceramic tile (exterior finishing material) is hooked on an extruded cement board having grooves provided on the surface and fastened with metal fittings. As shown in FIG. 7, the extrusion-molded cement board 1 has a concave portion 3 with a dovetail groove on one side, and this concave portion 3 has a shape of a dovetail groove 5 on one side wall, and the other side wall is vertical, A projection 7 is provided at the outer end thereof, whereby a side wall recess 9 surrounded by the projection 7 is formed along the depth of the cement board 1 on the side wall. The convex portion 13 formed on the back surface of the ceramic tile 11 is fitted into the concave portion 3. Next, the mounting bracket 15 is disposed in the space between the cement plate 1 and the ceramic tile 11. This mounting bracket 15 is provided with a spring coil type spring 17 inside the mounting bracket. The free end of the spring 17 is fitted into the side wall recess 9 of the recess 3 of the cement plate 1, and swinging is prevented by the protrusion 7. Further, the other end portion of the metal fitting 15 is engaged with the upper end of the ceramic tile 11.

また、特許文献2には、押出成形セメント板表面に凹部を設け、凹部内にアンカーボルトを介して金物により仕上材を取り付ける肉厚外装材の取付構造が開示されている。図8に示すように、石綿セメント中空板21の外表面23に凹部を形成し、この凹部の背部に補強金物25を配設するとともに、凹部内においてアンカーボルト27を介して補強金物25をファスナー29に固着し、ファスナー29に設けたダボピン31を肉厚外装材33の端面に穿設したダボ穴35に嵌入して取り付けている。   Patent Document 2 discloses an attachment structure for a thick exterior material in which a concave portion is provided on the surface of an extruded cement plate, and a finishing material is attached to the inside of the concave portion with a metal fitting via an anchor bolt. As shown in FIG. 8, a recess is formed in the outer surface 23 of the asbestos-cement hollow plate 21, and a reinforcement metal 25 is disposed on the back of the recess, and the reinforcement metal 25 is fastened to the fastener via an anchor bolt 27 in the recess. The dowel pin 31 provided on the fastener 29 is fitted into and attached to the dowel hole 35 formed in the end face of the thick exterior material 33.

しかしながら、特許文献1に開示される複合建材は、押出成形セメント板に蟻溝を設け、仕上材を引っ掛けるため、施工性は良いものの、取り付けることのできるものが、タイルや石など、仕上材裏面側に引っ掛けるためのリブ(凸部13)が設けられたものに限られてしまう。また、リブでタイルなど外装仕上材を固定することから、強度も要求され、大型のタイルなどではこの構造を用いることができなかった。さらに、一度取り付けると、破損した場合に取替えなどが困難であった。
一方、特許文献2に開示される肉厚外装材の取付構造は、押出成形セメント板の中空部を利用して仕上材を取り付けるのに、押出成形セメント板の表面に穴を開け、アンカーなどを設置して留付けを行なっていたため、表面に穴を開けることで、外装仕上材と押出成形セメント板の間の空間に浸入した水が、穴から中空部に浸入し、さらにそれが室内側にも浸入する恐れがあった。また、この穴が、熱や遮音性の低下を招くなど、外壁としての性能を低下させる要因となる恐れがあった。そして、一度取り付けると、破損した場合に取替えなどが困難であった。また、穴開け加工によるコストアップも避けられなかった。
本発明は上記状況に鑑みてなされたもので、外装仕上材を、簡素な構造で高強度かつ容易に取付けできる外装仕上材の取付構造を提供することにある。
However, the composite building material disclosed in Patent Document 1 is provided with dovetails on the extrusion-molded cement board and hooks the finishing material, so the workability is good, but what can be attached is the back of the finishing material such as tiles and stones. It will be restricted to what was provided with the rib (convex part 13) for hooking to the side. Further, since the exterior finishing material such as a tile is fixed with a rib, strength is required, and this structure cannot be used for a large tile or the like. In addition, once installed, it has been difficult to replace if it is damaged.
On the other hand, the attachment structure of the thick exterior material disclosed in Patent Document 2 uses a hollow portion of the extrusion-molded cement board to attach a finishing material. Since it was installed and tightened, the water that entered the space between the exterior finish and the extruded cement board entered the hollow part from the hole, and also entered the indoor side by making a hole in the surface. There was a fear. Further, this hole may cause a decrease in performance as an outer wall, for example, causing a decrease in heat and sound insulation. Once installed, it is difficult to replace it when it is damaged. In addition, cost increases due to drilling were inevitable.
The present invention has been made in view of the above situation, and it is an object of the present invention to provide a mounting structure for an exterior finishing material that can easily attach the exterior finishing material with a simple structure with high strength.

上記目的を達成するための本発明に係る請求項1記載の外装仕上材の取付構造は、押し出し方向を横方向にして建物躯体に張られる押出成形セメント板と、該押出成形セメント板の表面上部に、押し出し方向に延在して一体成形され上端面が前記表面に向かって下り勾配となる引っ掛け面で形成された上部凸条と、前記押出成形セメント板の表面下部に、押し出し方向に延在して一体成形され下端面が前記表面に向かって上がり勾配となる傾斜面で形成された下部凸条と、前記上部凸条の前記引っ掛け面に係止する鋭角に折り曲げられた掛止片が上辺部に沿って形成されるとともに、下部が前記下部凸条の前記傾斜面に螺合手段を介して係合される中継取付板と、背面の少なくとも横方向の二カ所に該中継取付板が固定される外装仕上材とを具備し、前記外装仕上材に固定された前記中継取付板の前記掛止片を前記上部凸条の引っ掛け面に掛止するとともに、該中継取付板の下部を前記螺合手段を介して前記下部凸条の傾斜面に係合させたことを特徴とする。   In order to achieve the above object, the exterior finishing material mounting structure according to claim 1 according to the present invention comprises an extruded cement board stretched on a building frame with the extrusion direction set in the lateral direction, and an upper surface of the extruded cement board. In addition, the upper ridge formed in the hooking surface extending in the extrusion direction and integrally formed and the upper end surface is inclined downward toward the surface, and the surface lower portion of the extruded cement board extends in the extrusion direction. The lower ridge formed by an inclined surface that is integrally formed and has a lower end surface that rises toward the surface, and a hook piece bent at an acute angle that engages with the hook surface of the upper ridge The relay mounting plate is formed along the portion, and the lower portion is engaged with the inclined surface of the lower ridge through screwing means, and the relay mounting plate is fixed at least in two lateral directions on the back surface. Exterior finishing materials And the latching piece of the relay mounting plate fixed to the exterior finishing material is hooked on the hooking surface of the upper ridge, and the lower part of the relay mounting plate is connected to the lower part via the screwing means. It is characterized by being engaged with the inclined surface of the ridge.

この外装仕上材の取付構造では、外装仕上材に中継取付板が取り付けられ、この中継取付板の掛止片が押出成形セメント板の上部凸条に引っ掛けられるとともに、中継取付板の下部が下部凸条の傾斜面に係合されることで、外装仕上材が中継取付板を介して押出成形セメント板に取り付けられる。したがって、外装仕上材には押出成形セメント板に直接取り付けするための凸部の形成されている必要がなくなる。これにより、凸部に十分な強度を得ることのできなかった大型のタイルなどが高い安全性で取り付け可能となる。また、中空部にアンカー等を設ける従来構造のように、押出成形セメント板の表面に穴を開ける必要もない。さらに、中継取付板と一体となった外装仕上材は、螺合手段の螺合解除を行うのみで取り外すことができ、また、新たな外装仕上材は中継取付板掛止片の引っ掛けと下部凸条への螺合のみで取り付けられる。   In this exterior finishing material mounting structure, a relay mounting plate is attached to the exterior finishing material, and the latching piece of this relay mounting plate is hooked on the upper ridge of the extruded cement plate, and the lower portion of the relay mounting plate is the lower convex. By being engaged with the inclined surface of the strip, the exterior finishing material is attached to the extruded cement board via the relay mounting plate. Therefore, it is not necessary for the exterior finishing material to be provided with a convex portion for direct attachment to the extruded cement board. This makes it possible to attach a large tile or the like that could not obtain sufficient strength to the convex portion with high safety. Further, unlike the conventional structure in which an anchor or the like is provided in the hollow portion, there is no need to make a hole in the surface of the extruded cement board. Furthermore, the exterior finishing material integrated with the relay mounting plate can be removed by simply unscrewing the screwing means, and the new exterior finishing material can be hooked on the relay mounting plate latching piece and the lower projection. It is attached only by screwing to the strip.

請求項2記載の外装仕上材の取付構造は、前記外装仕上材が、保水性を有するガーデンマットからなり、前記中継取付板の下部に支持板が設けられ、前記ガーデンマットの取り付けられた前記押出成形セメント板が上下方向に複数張られることで形成された前記ガーデンマット同士間の間隙には、所定の間隔で散水管と水切プレートが前記支持板に取り付けられたことを特徴とする。   The exterior finishing material mounting structure according to claim 2, wherein the exterior finishing material comprises a garden mat having water retention, a support plate is provided below the relay mounting plate, and the extrusion to which the garden mat is attached. In a gap between the garden mats formed by stretching a plurality of molded cement plates in the vertical direction, a water spray pipe and a draining plate are attached to the support plate at a predetermined interval.

この外装仕上材の取付構造では、外装仕上材を高強度に取り付けるための中継取付板が利用されて、支持板が付設可能となり、上下方向で隣接するガーデンマット同士間の間隙に、この支持板によって、散水管又は水切プレートが取り付け可能となる。   In this exterior finishing material mounting structure, a relay mounting plate for attaching the exterior finishing material with high strength is used, and a support plate can be attached, and this support plate is placed in the gap between adjacent garden mats in the vertical direction. By this, it becomes possible to attach a watering pipe or a draining plate.

本発明に係る請求項1記載の外装仕上材の取付構造によれば、外装仕上材に中継取付板を取り付け、この中継取付板を、押出成形セメント板の上部凸条に引っ掛け、下部凸条に係合させて取り付けるので、外装仕上材には押出成形セメント板に直接取り付けするための凸部の形成されている必要がない。これにより、凸部に十分な強度を得ることのできなかった大型のタイル等を高い安全性で取り付けることができる。また、中空部にアンカー等を設ける従来構造のように、押出成形セメント板の表面に穴を開ける必要がないので、漏水の発生を防止できるとともに、熱や遮音性の低下を招く等、外壁としての性能低下を防止することとができる。さらに、中継取付板と一体となった外装仕上材は、螺合手段の螺合解除を行うのみで取り外すことができ、また、新たな外装仕上材は中継取付板掛止片の引っ掛けと下部凸条への螺合のみで取り付けできるので、取り外し・取り付けを容易に行え、高い交換作業性を確保することができる。   According to the mounting structure of the exterior finishing material according to claim 1 of the present invention, the relay mounting plate is attached to the exterior finishing material, and the relay mounting plate is hooked on the upper ridge of the extruded cement plate, Since it is engaged and attached, it is not necessary for the exterior finishing material to have a convex part for direct attachment to the extruded cement board. Thereby, a large tile or the like for which sufficient strength could not be obtained at the convex portion can be attached with high safety. In addition, unlike the conventional structure in which an anchor or the like is provided in the hollow portion, it is not necessary to make a hole in the surface of the extrusion-molded cement plate, so that the occurrence of water leakage can be prevented and heat and sound insulation properties can be reduced. It is possible to prevent a decrease in performance. Furthermore, the exterior finishing material integrated with the relay mounting plate can be removed by simply unscrewing the screwing means, and the new exterior finishing material can be hooked on the relay mounting plate latching piece and the lower projection. Since it can be attached only by screwing to the strip, it can be easily removed and attached, and high replacement workability can be ensured.

本発明に係る請求項2記載の外装仕上材の取付構造によれば、外装仕上材を高強度に取り付けるための中継取付板を利用して、支持板を付設することが可能となり、上下方向で隣接する外装仕上材同士間の間隙に、この支持板によって散水管又は水切プレートを取り付けることができ、外装仕上材にガーデンマットを用いた緑化パネルの給排水構造を、少ない部品による簡素な構造で、容易にかつ効果的に構成することができる。   According to the mounting structure for an exterior finishing material according to claim 2 of the present invention, it becomes possible to attach a support plate using a relay mounting plate for attaching the exterior finishing material with high strength, and in the vertical direction. A watering pipe or draining plate can be attached to the gap between adjacent exterior finishing materials by this support plate, and the water supply / drainage structure of the greening panel using a garden mat as the exterior finishing material is a simple structure with few parts, It can be configured easily and effectively.

以下、本発明に係る外装仕上材の取付構造の好適な実施の形態を図面を参照して説明する。

DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of an exterior finishing material mounting structure according to the invention will be described with reference to the drawings.
1 is a longitudinal sectional view showing a mounting structure of an exterior finishing material according to the present invention, FIG. 2 is a view taken along the line AA in FIG. 1, FIG. 3 is a view taken along the line BB in FIG. Fig. 5 is a longitudinal sectional view showing a modified example of the mounting structure shown in Fig. 1.
As shown in FIG. 1, a bracket 35 is welded and fixed to an outer surface 33 of a steel column 31 that is a building frame. One piece 37a of an angle member 37 having an L-shaped cross section and extending vertically is fixed to the bracket 35 by welding. Therefore, the angle member 37 extends vertically with the other piece 37 b parallel to the outer surface 33 of the steel column 31.

このアングル材37の片部37bにはZクリップ39を介して押出成形セメント板41が取り付けられている。すなわち、押出成形セメント板41の中空部43にはプレートナット45が挿入され、押出成形セメント板41の背面47にはZクリップ39の一端を貫通したボルト49がプレートナット45に螺合されている。押出成形セメント板41は、背面47がパッキン51を介してアングル材37の片部37bに当接されている。つまり、押出成形セメント板41は、背面47と、この背面47に固定されたZクリップ39とで片部37bを挟持してアングル材37に取り付けられている。また、押出成形セメント板41は、上下に隣接する複数枚毎に、アングル材37に溶接固定された支持アングル53によって下端が支持されている。   An extrusion-molded cement board 41 is attached to a piece 37 b of the angle member 37 via a Z clip 39. That is, a plate nut 45 is inserted into the hollow portion 43 of the extruded cement plate 41, and a bolt 49 penetrating one end of the Z clip 39 is screwed to the plate nut 45 on the back surface 47 of the extruded cement plate 41. . The extruded cement board 41 has a back surface 47 in contact with a piece 37 b of the angle member 37 through a packing 51. That is, the extrusion-molded cement board 41 is attached to the angle member 37 with the piece portion 37 b sandwiched between the back surface 47 and the Z clip 39 fixed to the back surface 47. Further, the lower end of the extruded cement board 41 is supported by a support angle 53 that is welded and fixed to the angle member 37 for each of a plurality of vertically adjacent cement boards.

押出成形セメント板41は、押し出し成形方向に中空部43が形成されている。本実施の形態による取付構造では、押出成形セメント板41の押し出し方向が横方向となるように、押出成形セメント板41が建物躯体に張り付けられる(所謂「横張り」とも称す)。図4に示すように、押出成形セメント板41は、上辺部が凸部55,下辺部が凹部57に形成され、上下で隣接する押出成形セメント板41、41同士は、これら凸部55と凹部57とを嵌合させて連結される。押出成形セメント板41、41同士の間に形成される目地には、ガスケットG、シーリングSが設けられる。   The extruded cement board 41 has a hollow portion 43 formed in the extrusion molding direction. In the mounting structure according to the present embodiment, the extrusion-molded cement board 41 is attached to the building frame so that the extrusion direction of the extrusion-molded cement board 41 is in the horizontal direction (also referred to as so-called “horizontal tension”). As shown in FIG. 4, the extruded cement board 41 is formed with a convex portion 55 on the upper side and a concave portion 57 on the lower side, and the extruded cement plates 41 and 41 adjacent to each other on the upper and lower sides are formed with the convex portion 55 and the concave portion. 57 and are connected. A gasket G and a sealing S are provided at the joint formed between the extruded cement plates 41 and 41.

押出成形セメント板41の表面59の上部には、押し出し方向に延在して一体成形され、上端面が表面59に向かって下り勾配となる引っ掛け面61で形成された上部凸条63が設けられている。また、押出成形セメント板41の表面59の下部には、押し出し方向に延在して一体成形され、下端面が表面59に向かって上がり勾配となる傾斜面65で形成された下部凸条67が設けられている。引っ掛け面61及び傾斜面65は、表面59との成す角度αが略50度程度となるように形成される。   On the upper portion of the surface 59 of the extrusion-molded cement board 41, there is provided an upper ridge 63 formed by a hooking surface 61 that extends in the extrusion direction and is integrally formed, and whose upper end surface is inclined downward toward the surface 59. ing. Further, a lower ridge 67 is formed at the lower portion of the surface 59 of the extrusion-molded cement board 41 and is integrally formed by extending in the extruding direction, and the lower end surface is formed by an inclined surface 65 that is inclined upward toward the surface 59. Is provided. The hook surface 61 and the inclined surface 65 are formed so that the angle α formed with the surface 59 is about 50 degrees.

押出成形セメント板41の表面59には、これら上部凸条63、下部凸条67を利用して外装仕上材69が取り付けられる。外装仕上材69は、中継取付板であるアタッチメント71を介して取り付けられる。アタッチメント71は、上部凸条63の引っ掛け面61に係止する鋭角に折り曲げられた掛止片73が上辺部に沿って形成されるとともに、下部が下部凸条67の傾斜面65に螺合手段であるボルト75を介して係合される。   An exterior finishing material 69 is attached to the surface 59 of the extrusion-molded cement board 41 using the upper ridge 63 and the lower ridge 67. The exterior finishing material 69 is attached via an attachment 71 that is a relay attachment plate. The attachment 71 is formed with a hooking piece 73 bent at an acute angle that engages with the hooking surface 61 of the upper ridge 63 along the upper side, and the lower part is screwed to the inclined surface 65 of the lower ridge 67. Is engaged through a bolt 75.

本実施の形態において、アタッチメント71は、上下方向に長い短冊状に形成される。アタッチメント71は、外装仕上材69の背面の少なくとも横方向の二カ所に固定される。本実施の形態では、図2に示すように、外装仕上材69の背面に、5つのアタッチメント71が固定される。アタッチメント71の大きさは、押出成形セメント板41の大きさに合わせて作成する。ボルト75は、概ね300〜600mm間隔で押出成形セメント板41の幅に応じて留め付ける。また、アタッチメント71と外装仕上材69とは、ボルトやアンカーなどで直接留め付ける。   In the present embodiment, the attachment 71 is formed in a strip shape that is long in the vertical direction. The attachment 71 is fixed to at least two lateral positions on the back surface of the exterior finishing material 69. In the present embodiment, as shown in FIG. 2, five attachments 71 are fixed to the back surface of the exterior finishing material 69. The size of the attachment 71 is created in accordance with the size of the extruded cement board 41. The bolts 75 are fastened according to the width of the extruded cement board 41 at intervals of approximately 300 to 600 mm. Further, the attachment 71 and the exterior finishing material 69 are directly fastened with bolts or anchors.

外装仕上材(表面装飾材)69としては、石、タイル、太陽電池パネル、緑化パネルなどを取り付けることができるが、アタッチメント71で取り付けることができる外装仕上材69であればこれに限定されない。また、押出成形セメント板41の形状は、アタッチメント71を取り付けることのできる形状であれば図例の形状に限定されるものではない。   As the exterior finishing material (surface decoration material) 69, stones, tiles, solar battery panels, greening panels, and the like can be attached, but the exterior finishing material 69 that can be attached by the attachment 71 is not limited thereto. Moreover, the shape of the extrusion-molded cement board 41 is not limited to the shape of the example as long as the attachment 71 can be attached.

このようにして、外装仕上材69に固定されたアタッチメント71の掛止片73を、上部凸条63の引っ掛け面61に掛止するとともに、アタッチメント71の下部をボルト75を介して下部凸条67の傾斜面65に係合させることで、外装仕上材69は、アタッチメント71を介して押出成形セメント板41の表面59に取り付けられることになる。   In this way, the hooking piece 73 of the attachment 71 fixed to the exterior finishing material 69 is hooked to the hooking surface 61 of the upper ridge 63, and the lower portion of the attachment 71 is connected to the lower ridge 67 through the bolt 75. The exterior finishing material 69 is attached to the surface 59 of the extruded cement board 41 via the attachment 71 by being engaged with the inclined surface 65.

また、上記の取付構造では、アタッチメント71の下部に螺合したボルト75を、押出成形セメント板41に設けた下部凸条67の傾斜面65に直接係合させる例を説明したが、本発明に係る取付構造は、その他、図5に示すように、L字状の金具77を用い、アタッチメント71の下部を、ボルト75を介して螺合した金具77によって傾斜面65に固定するものであってもよい。このような取付構造の変形例によれば、アタッチメント71の下部を垂直状態に形成して下部凸条67に固定でき、下部に曲げ部79(図1参照)を形成する構造に比べ、ラフな寸法精度での取付けが可能となり、上下方向のアタッチメント71の製造精度を緩和することができる。   Further, in the above mounting structure, the example in which the bolt 75 screwed to the lower portion of the attachment 71 is directly engaged with the inclined surface 65 of the lower protrusion 67 provided on the extruded cement plate 41 has been described. In addition, as shown in FIG. 5, the mounting structure uses an L-shaped metal fitting 77 and fixes the lower part of the attachment 71 to the inclined surface 65 by a metal fitting 77 screwed through a bolt 75. Also good. According to such a modification of the mounting structure, the lower portion of the attachment 71 can be formed in a vertical state and fixed to the lower protrusion 67, which is rough compared to a structure in which a bent portion 79 (see FIG. 1) is formed in the lower portion. Mounting with dimensional accuracy is possible, and the manufacturing accuracy of the attachment 71 in the vertical direction can be relaxed.

したがって、この外装仕上材69の取付構造によれば、外装仕上材69にアタッチメント71を取り付け、このアタッチメント71を、押出成形セメント板41の上部凸条63に引っ掛けるとともに、下部凸条67に係合させて取り付けるので、外装仕上材69には押出成形セメント板41へ直接取り付けするための凸部を形成する必要がない。これにより、凸部に十分な強度を得ることのできなかった大型のタイル等を高い安全性で取り付けることができる。また、中空部43にアンカー等を設ける従来構造のように、押出成形セメント板41の表面59に穴を開ける必要がないので、漏水の発生を防止できるとともに、熱や遮音性の低下を招く等、外壁としての性能低下を防止することとができる。さらに、アタッチメント71と一体となった外装仕上材69は、ボルト75の螺合解除を行うのみで取り外すことができ、また、新たな外装仕上材69はアタッチメント掛止片73の引っ掛けと下部凸条67への螺合のみで取り付けできるので、取り外し・取り付けを容易に行え、高い交換作業性を確保することができる。   Therefore, according to the mounting structure of the exterior finishing material 69, the attachment 71 is attached to the exterior finishing material 69, and the attachment 71 is hooked on the upper ridge 63 of the extrusion-molded cement plate 41 and engaged with the lower ridge 67. Therefore, it is not necessary to form the convex part for attaching directly to the extrusion-molded cement board 41 in the exterior finishing material 69. Thereby, a large tile or the like for which sufficient strength could not be obtained at the convex portion can be attached with high safety. Further, unlike the conventional structure in which an anchor or the like is provided in the hollow portion 43, it is not necessary to make a hole in the surface 59 of the extrusion-molded cement plate 41, so that leakage of water can be prevented and heat and sound insulation properties are reduced. It is possible to prevent performance degradation as an outer wall. Further, the exterior finishing material 69 integrated with the attachment 71 can be removed simply by unscrewing the bolt 75, and the new exterior finishing material 69 can be attached to the attachment retaining piece 73 and the lower ridge. Since it can be attached only by screwing to 67, it can be easily detached and attached, and high replacement workability can be ensured.

次に、本発明に係る外装仕上材の取付構造の第2の実施の形態を説明する。
図6は本発明に係る取付構造の第2の実施の形態を表す縦断面図である。なお、図1〜図4に示した部材と同一の部材には同一の符号を付し、重複する説明は省略するものとする。
この実施の形態による取付構造では、外装仕上材69が、保水性を有するガーデンマット69Aからなる。このガーデンマット69Aは、例えばヤシノミ繊維を圧縮保形して作られる。また、アタッチメント71の下部には支持板81が設けられている。支持板81は、例えばガーデンマット69Aとアタッチメント71との間に挟着される。
Next, a second embodiment of the exterior finishing material mounting structure according to the present invention will be described.
FIG. 6 is a longitudinal sectional view showing a second embodiment of the mounting structure according to the present invention. In addition, the same code | symbol is attached | subjected to the member same as the member shown in FIGS. 1-4, and the overlapping description shall be abbreviate | omitted.
In the mounting structure according to this embodiment, the exterior finishing material 69 is composed of a garden mat 69A having water retention. The garden mat 69A is made, for example, by compressing and retaining palm flea fibers. A support plate 81 is provided below the attachment 71. For example, the support plate 81 is sandwiched between the garden mat 69 </ b> A and the attachment 71.

この取付構造では、ガーデンマット69Aの取り付けられた押出成形セメント板41が上下方向に複数張られることで、ガーデンマット69A同士間に間隙83が形成される。この複数の間隙83には、所定の間隔で散水管85が支持板81に取り付けられ、最下部には水切プレート87が支持板81に取り付けられる。散水管85の取り付け間隔は、緑化物の種類によって変えることができる。また、散水管85は、ガーデンマット69Aが取り付けられた押出成形セメント板(緑化パネル)毎に取り付けたり、緑化パネル複数枚(段)毎に取り付けるものであってもよい。 水切プレート87は、散水した水が押出成形セメント板41の下部から滴下し、下側の緑化していない押出成形セメント板41を汚すのを防止するよう、滴下水を受けて排水する。この水切プレート87は、基本的には、最下段の緑化パネルに取り付けられるが、中間部分に取り付けられるものであってもよい。   In this attachment structure, a plurality of extruded cement boards 41 to which the garden mat 69A is attached are stretched in the vertical direction, whereby a gap 83 is formed between the garden mats 69A. In the plurality of gaps 83, water spray pipes 85 are attached to the support plate 81 at predetermined intervals, and a draining plate 87 is attached to the support plate 81 at the lowermost part. The attachment interval of the water sprinkling pipe 85 can be changed depending on the type of the greenery. Moreover, the water spray pipe 85 may be attached to each extrusion-molded cement board (greening panel) to which the garden mat 69A is attached, or may be attached to every plurality of greening panels (stages). The draining plate 87 receives and drains the dropped water so as to prevent the sprinkled water from dripping from the lower part of the extruded cement board 41 and soiling the lower unextruded extruded cement board 41. The draining plate 87 is basically attached to the lowermost greening panel, but may be attached to an intermediate portion.

したがって、この取付構造によれば、ガーデンマット69Aを高強度に取り付けるためのアタッチメント71を利用して、支持板81を付設することが可能となり、上下方向で隣接するガーデンマット69A同士間の間隙83に、この支持板81によって散水管85又は水切プレート87を取り付けることができる。その結果、外装仕上材69にガーデンマット69Aを用いて構成した緑化パネルなどの給排水構造を、少ない部品による簡素な構造で、容易にかつ効果的に構成することができる。   Therefore, according to this attachment structure, it is possible to attach the support plate 81 using the attachment 71 for attaching the garden mat 69A with high strength, and the gap 83 between the garden mats 69A adjacent in the vertical direction is provided. Further, the water spray pipe 85 or the draining plate 87 can be attached by the support plate 81. As a result, a water supply / drainage structure such as a greening panel configured by using the garden mat 69A as the exterior finishing material 69 can be easily and effectively configured with a simple structure with few parts.
