Description

【０００１】
【発明の属する技術分野】
本発明は，外壁板を，その長手方向を上下方向にして，建物の構造躯体に胴縁を使用することなく直接に留め付けてなる縦張直張外壁施工構造及びこれに用いるスタータ金具並びに中間水切に関する。
【０００２】
【従来の技術】
従来より，外壁板を，その長手方向を上下方向にして，建物の構造躯体に留め付ける縦張外壁施工構造がある（特許文献１参照）。
該縦張外壁施工構造においては，例えば，図１６に示すごとく，外壁板２は，構造躯体９０に対して横胴縁９９を介して留め付けられている。これにより，上記外壁板２と構造躯体９０との間に，充分な空間を有する通気層９１を確保している。
【０００３】
そして，建物の土台部においては，図１６に示すごとく，上記外壁板２の下端部２１を支承するスタータ金具９３が配設されている。該スタータ金具９３は，断面略Ｌ字状の金具であって，上記構造躯体９０に固定する基板部９３１と上記外壁板２を支承する支承板部９３４とからなる。上記基板部９３１と支承板部９３４との間には，金属板を局部的に変形させることにより形成した補強リブ９３８が形成されている。
【０００４】
上記スタータ金具９３は，上記外壁板２の表側面２５を伝って流下してきた雨水を前方へ排出する土台水切９４と重ね合わせるようにして，土台部の土台柱９０３に，ビス９９２によって固定されている。
また，上記外壁板２の側端部は，上記横胴縁９９に固定された留め付け金具９６によって係止されている。また，上記構造躯体９０の前面には，防水紙９８を貼付してある。

【発明が解決しようとする課題】
しかしながら，上記従来の縦張外壁施工構造９は，上述のごとく，横胴縁９９を配設するため構成要素が多くなる。その結果，施工工数が多く，材料コストが高くなるという問題がある。
また，上記外壁板２の重量は，上記断面Ｌ字状のスタータ金具９３によって支えることとなるが，上記重量は，力学的な支点となるスタータ金具９３の支承板部９３４の基端部９３３から大きく前方に離れた位置にかかる。そのため，上記支承部９３４にかかる荷重のモーメントが大きくなり，上記外壁板２の重量が大きい場合には，上記スタータ金具９３の強度が不充分となるおそれがある。
【０００７】
また，上記外壁板２の前後位置は，側端部に配される留め付け金具９６によって位置決めされることとなるが，上記外壁板２の下端部２１には，特に位置決め用の部材がない。そのため，上記外壁板２の下端部２１の前後位置を正確に位置決めすることが困難となるおそれがある。
【０００８】
また，特許文献２の図３に示すような断面形状のスタータ金具を用いることも考えられるが，該スタータ金具の形状は複雑である。そのため，押出成形等を用いて上記スタータ金具を製作する必要があるなど，製造コストが高くなるという問題がある。
また，複数階建ての建物における上下に隣り合う階層の間の中間部に，２階部等施工のために，上記スタータ金具を配設する場合にも，上述したと同様の問題が起こる。
【０００９】
本発明は，かかる従来の問題点に鑑みてなされたもので，外壁板の重量に対する耐荷重性能に優れ，外壁板の前後位置の位置決めが容易であり，かつ，安価な縦張直張外壁施工構造及びこれに用いるスタータ金具並びに中間水切を提供しようとするものである。

【００１３】
また，上記スタータ金具の脚部は，上記土台水切の水平段部に載置されている。これにより，上記スタータ金具と土台水切とを，両者の上下位置関係を正確に維持しつつ，容易に施工することができる。そのため，土台水切と外壁板との上下位置関係を正確に保つことができる。
【００１４】
また，上記スタータ金具は，上記当接板部を有し，該当接板部が上記外壁板の裏側面に当接している。そのため，上記外壁板の前後位置の位置決めを，その下端部において容易に行うことができ，通気層を確実に形成することができる。

この場合において，外壁板の許容移動距離を２ｍｍと設定すると，スタータ金具に対する許容荷重は，上記試験における鉄板２９の移動距離２ｍｍのときの荷重である。従って，実施例１のスタータ金具３の許容荷重は４４５０Ｎであり，従来例のスタータ金具９３の許容荷重は１５１６Ｎである。
【００７６】
そして，上記外壁板として重量２３．５ｋｇのものを用いる場合，スタータ金具に掛かる荷重は約２３０Ｎである。

[Problems to be solved by the invention]
However, as described above, the conventional vertical outer wall construction structure 9 has a large number of components because the horizontal trunk edge 99 is disposed as described above. As a result, there are problems that the number of construction steps is large and the material cost is high.
The weight of the outer wall plate 2 is supported by the starter fitting 93 having an L-shaped cross section. However, the weight is determined from the base end portion 933 of the support plate portion 934 of the starter fitting 93 serving as a dynamic fulcrum. It takes a large distance away. For this reason, when the moment of the load applied to the support portion 934 is increased and the weight of the outer wall plate 2 is large, the strength of the starter fitting 93 may be insufficient.
[0007]
Further, the front and rear positions of the outer wall plate 2 are positioned by fastening metal fittings 96 arranged on the side end portions, but the lower end portion 21 of the outer wall plate 2 has no particular positioning member. Therefore, it may be difficult to accurately position the front and rear positions of the lower end portion 21 of the outer wall plate 2.
[0008]
Further, although it is conceivable to use a starter fitting having a cross-sectional shape as shown in FIG. 3 of Patent Document 2, the shape of the starter fitting is complicated. For this reason, there is a problem that the manufacturing cost becomes high, for example, it is necessary to manufacture the starter metal fitting using extrusion molding or the like.
In addition, the same problem as described above also occurs when the above-mentioned starter metal fitting is arranged for the construction of the second floor portion, etc., in the middle portion between the upper and lower adjacent levels in a multi-storey building.

DETAILED DESCRIPTION OF THE INVENTION
In the first invention (invention 1), as the outer wall plate, for example, a ceramic-based outer wall plate can be used.
Further, “directly fastening to the structural housing” means that the outer wall plate is directly secured to the structural housing without interposing a base material such as a trunk edge, and so-called direct installation is performed.
[0032]
Also, in this specification, the outside direction of the building is expressed as “front”, and the inside direction is expressed as “rear”. In addition, for each member in the above-mentioned vertical straight wall construction structure, the front, rear, top, and bottom directions in the construction state are respectively “front”, “rear”, “upper”, “lower”. It expresses.
[0033]
Moreover, it is preferable that the said leg part of the said starter metal fitting is made to contact | abut the back end to the said back-plate part of the said foundation draining (Claim 2).
In this case, the strength against the load of the outer wall plate applied to the support plate portion can be further increased.
[0034]
Next, in the second invention (invention 3), it is preferable that a rear end of the leg portion of the starter fitting is in contact with the back plate portion of the intermediate drainer (invention 4).
In this case, the strength against the load of the outer wall plate applied to the support plate portion can be further increased.
[0035]
Moreover, it is preferable that the said ventilation layer has a thickness of 10-20 mm.
In this case, the air permeability between the structural housing and the outer wall plate can be sufficiently ensured while ensuring the load bearing performance against the weight of the outer wall plate. If the thickness of the ventilation layer is less than 10 mm, the air permeability between the structural housing and the outer wall plate may be insufficient. On the other hand, if the thickness exceeds 20 mm, the load moment of the outer wall plate applied to the starter fitting increases, and it may be difficult to reliably support the outer wall plate by the starter fitting.
[0036]
Next, in the third invention (invention 6), it is preferable that the leg portion has a rear end thereof disposed substantially on the same plane as the rear surface of the substrate portion (invention 7).

As well as an intermediate drainer.
[0068]
(Example 2)
In this example, as shown in FIGS. 14 and 15, the load bearing strength with respect to the weight of the outer wall plate is measured for the starter fitting 3 according to the present invention shown in Example 1, and compared with the starter fitting 93 shown in the conventional example. This is an example.
[0069]
As the starter metal fitting 3 of Example 1, one having a height h = 35 mm, a front-rear width d = 24 mm, and a left-right width w = 150 mm was used (see FIGS. 8 and 9).
On the other hand, the conventional starter fitting 93 has a substantially L-shaped cross section with a height of 40 mm, a front-rear width of 27 mm, and a left-right width of 150 mm.
Each starter fitting is formed by bending a stainless steel plate (SUS304) having a thickness of 1.2 mm.
[0070]
In the test, as shown in FIG. 14, first, the starter fitting 3 as a sample is fixed to the C-shaped steel 19 having a thickness of 2.3 mm and a cross-sectional dimension of 100 × 50 mm together with the foundation drainer 4. The base drainer 4 has the shape shown in Example 1, and is formed by bending a plated steel plate having a thickness of 0.35 mm.
[0071]
The starter fitting 3 was fixed to the C-shaped steel 19 at two points with a tex screw 193 having a diameter of 4 mm and a length of 19 mm.
In this state, an iron plate 29 having a thickness of 10 mm is placed vertically on the support plate portion 34 of the starter metal fitting 3 so that the distance B from the C-shaped steel 19 is 15 mm. A load was applied downward (arrow F). The descending speed of the iron plate 29 at this time was 10 mm / min.
[0072]
Then, the load applied to the starter fitting 3 was measured at each time when the moving distance of the iron plate 29 after the start of applying the load to the starter fitting 3 was 1 mm, 2 mm, and 3 mm. This measurement was performed using three specimens.
Further, as shown in FIG. 15, the measurement was performed in the same manner as described above for the starter fitting 93 of the conventional example.
Table 1 shows the measurement results.
[0073]
[Table 1]

[0074]
As can be seen from Table 1, the load applied to the starter fitting 3 of Example 1 is much larger than the load applied to the starter fitting 93 of the conventional example at the same moving distance of the iron plate 29. This means that the starter fitting 3 of the first embodiment has an extremely large load bearing strength than the starter fitting 93 of the conventional example.
[0075]
In addition, assuming that the starter metal fitting is used at the lower end of the left and right joints of the outer wall plate at a pitch of 455 mm, that is, assuming that one outer wall plate is received by one starter metal fitting, the above results are obtained. Consider.
In this case, if the allowable moving distance of the outer wall plate is set to 2 mm, the allowable load on the starter fitting is the load when the moving distance of the iron plate 29 in the above test is 2 mm. Therefore, the allowable load of the starter fitting 3 of the first embodiment is 4450N, and the allowable load of the starter fitting 93 of the conventional example is 1516N.
[0076]
When the outer wall plate having a weight of 23.5 kg is used, the load applied to the starter fitting is about 230 N.
Therefore, the starter fitting 3 of the first embodiment can withstand a load that is 19.3 times the load received from the outer wall plate in the assumed specifications, particularly when no external force is applied. On the other hand, the load that can be withstood by the starter fitting 93 of the conventional example is stopped at 6.58 times the load received from the outer wall plate particularly when no external force is applied.
Thus, it can be seen from the results of this example that the starter fitting of Example 1 according to the present invention is excellent in load bearing strength.
[0077]
