Using color stainless steel or color titanium plate for the surface material,
The surface embossing is processed so that it looks like an acute angle (step difference of 0.8 mm or more), and the strength of the connecting part is strengthened to make it a sturdy structure. It is a thing.

ともに、現場施工の吹付材に比較するとフラットな模様
しか得られなかった。<Problems to be solved by the invention> However, since such a conventional one mainly uses a colored zinc drawn iron plate as a surface material, adhesion of iron powder generated during cutting on site or generation from a cut surface occurs. It had the drawback of a short service life in an environment where it rusted and sea salt particles scattered near the coast. In addition, since the surface embossing also has low processing accuracy and shallow carving, it is not useful for improving bending strength, and only a flat pattern was obtained compared to the sprayed material on site construction.
また、パネルとパネルの連結部についても、それぞれ工
夫はしてあるが、防水性が不充分であり、しかも連結部
が捩れ易く、連結部の強度や防水性に問題があった。Further, although the panel and the connecting portion of the panel have been devised respectively, the waterproofness is insufficient, and the connecting portion is easily twisted, so that there is a problem in strength and waterproofness of the connecting portion.
さらにパネル裏面には断熱性を目的として、ウレタンフ
ォームやイソシアヌレートフォームが使用されている
が、これらは燃焼性があり発煙量も多いという欠点があ
るとともに、表面材のエンボス加工の彫りが浅いもので
あるため、表面材と裏打材（断熱材）との接着力が弱
く、剥がれ易いという欠点があった。Furthermore, urethane foam and isocyanurate foam are used on the back surface of the panel for the purpose of heat insulation, but they have the drawback of being flammable and producing a large amount of smoke, and the surface material is not embossed for engraving. Therefore, there is a drawback that the adhesive force between the surface material and the backing material (heat insulating material) is weak and the material is easily peeled off.
〈問題点を解決するための手段〉 すなわち、従来のこような欠点を解消するためには、板
全体及び連結部の強度を上昇させる必要がある。<Means for Solving the Problems> That is, in order to eliminate the drawbacks of the related art, it is necessary to increase the strength of the entire plate and the connecting portion.

し、エンボス加工の彫りを深くすると、連結部に生じる
空隙も大きなものとなり、防水性能や耐火性能が劣るも
のとなってしまい、建築用外壁板として使用に適さない
ものとなってしまう。If the engraved carving is deep, they can be interlocked with each other at the time of connection to increase the connection strength, and the rib effect of the embossing can prevent twisting and reduce bending, thereby increasing the strength of the entire plate. However, if the embossing is deeply carved, the voids formed in the connecting portion also become large, resulting in poor waterproof performance and fire resistance performance, which makes it unsuitable for use as a building exterior wall board.
従って、エンボス加工の彫りの深いものを使用する場合
には、連結部の防水性能を確保するための工夫が必要で
ある。そして、連結部の防水性能を向上させるために
は、連結部に傾斜面を設けることが有効であることがわ
かった。Therefore, when using a deeply embossed product, it is necessary to devise a method for ensuring the waterproof performance of the connecting portion. Further, it has been found that it is effective to provide the connecting portion with an inclined surface in order to improve the waterproof performance of the connecting portion.
一方、傾斜面を設けると、その部分は板の厚さが薄くな
ることになり、従来のウレタンフォームやイソシアヌレ
ートフォームでは十分な耐火性能を確保できない。ま
た、連結部の空隙も大きいので、連結部の耐火性能を十
分なものとする必要がある。On the other hand, when the inclined surface is provided, the thickness of the plate becomes thin at that portion, and the conventional urethane foam or isocyanurate foam cannot secure sufficient fire resistance performance. Further, since the voids in the connecting portion are large, it is necessary to make the fire resistance performance of the connecting portion sufficient.

In the formed exterior wall board for lateral attachment, the backing material 3 is phenol foam, and the surface material 1 is a stainless steel plate or titanium plate that has been embossed on both sides with a step of 0.8 mm or more, and the lower edge part has a surface material. 1 is continuously bent so that the front side portion has a thickness of about half and a concave female connecting portion 4 opened downward is formed on the back side portion, and the plate thickness is increased by the inclined surface 8 at the upper edge portion. After making the thickness to match the connecting portion 4, the surface material 1 is continuously bent to form a convex insertion portion 9 slightly longer than the female connecting portion 4.
A male type connecting portion 5 is formed on the back side thereof and an inserting groove 10 opened upward so that the inserting portion 7 of the female type connecting portion 4 can be inserted.

強度も低下する。<Function> The strength of the joint portion and the strength of the entire plate are increased by using the color stainless steel plate or the color titanium plate which is embossed on both sides and has a step of 0.8 mm or more as the surface material. On the other hand, although the gap of the connecting portion becomes large, the inclined surface of the connecting portion prevents water leakage from the connecting portion. In addition, phenol foam ensures sufficient fire resistance even in thin-walled areas. From the viewpoint of both the strength of the connecting portion and the fireproof performance of the connecting portion, it is appropriate that the connecting portions each have a wall thickness of about half (upper plate and lower plate to be connected). Increasing the thickness of either the upper plate or the lower plate inevitably reduces the thickness of the other, resulting in poor fire resistance and weakening of the strength of that part alone, as well as easy twisting. As a result, the strength of the connecting portion also decreases.

A female connecting portion 4 is formed on the lower edge portion, and a male connecting portion 5 is formed on the upper edge portion. The surface material 1 is formed by embossing both sides of a thin plate of color stainless steel to have a step of 0.8 mm or more. Further, when the surface material 1 is a titanium plate, the corrosion resistance is further improved, and the weight can be remarkably reduced as compared with the stainless plate.

水対策及び捩れ防止のために裏側に曲折しておく。The female connecting portion 4 at the lower edge is formed by bending the surface material 1 as follows. The lower end of the surface material 1 is bent so as to have a thickness of about half and extended upward, and then bent downward and the insertion groove 6 is formed in the back side portion. Then, this is further extended to the lower end so as to have the same length as the insertion groove to form the insertion portion 7. Then, the lower end is bent back to prevent waterproofing and twist.

The surface material 1 has a thickness that matches the position of the insertion groove 6 of the female connecting portion 4 by the inclined surface 8. Then, the insertion portion 9 is formed by extending the female connecting portion 4 slightly longer than the length of the insertion groove 6, bending it to match the thickness of the insertion groove, and extending downward. Then, the insertion groove 10 is formed by extending the female connecting portion 4 for a length corresponding to the insertion portion 7 and then bending it. Further, it is extended to a position above the insertion portion 9 to form an extension portion 11, and the upper end of the extension portion is bent to the back side and attached to the waterproof portion 12.

Also, as shown in FIG. 4, the waterproof rib 13 may be formed by bending the insertion portion 7 of the female type coupling portion 4 in a mountain shape to the back side. In some cases, a plurality of waterproof ribs 13 may be formed as shown in FIGS. 6 and 7.
表面材１の表側の化粧面14には図示したように化粧溝15

明な模様を作り出すことが可能になった。Here, a method of performing deep embossing on the color stainless steel plate, that is, a double-sided embossing process with a step difference of 0.8 mm or more, which has been impossible in the past, will be described. With the conventional method, even if both sides are embossed, only a step difference of up to 0.6 mm can be embossed. In order to perform embossing on both sides with a step of 0.8 mm or more, a film original with a pattern that is repeatedly corrected so that the upper and lower rolls are bitten is produced, and a maximum depth of 1.5 mm is etched by etching. Re-hardening after etching extends the life of the roll and enables deep embossing. Since both sides are embossed with the deeply engraved rolls, it is possible to create a clear pattern on the color stainless steel material by double-sided embossing with a deep step difference of 0.8 mm or more.

工のリブ的効果により曲げ強さが向上するという効果も
ある。Moreover, since the unevenness increases due to the deep engraving, the bonding between the panels becomes strong and becomes difficult to come off, and the adhesiveness of the phenol foam is improved. There is also an effect that the bending strength is improved by the rib effect of the embossing.
なお、発明者が連結部の引き抜き試験及び曲げ強度試験
したところによれば、エンボス加工の段差0.8mmと0.6mm
と0.3mmを比較すると、0.3mmと0.6mmのものでは0.6mmも
のは0.3mmのものに比べて引き抜き試験，曲げ強度試験
ともに約１割値が上昇する。一方、0.6mmと0.8mmのもの
では0.8mmものは0.6mmのものに比べて引き抜き試験では
約３倍の値となり、曲げ強度試験でも約２倍の値とな
る。0.8mmと0.6mmの段差では段差の大きさは約３割しか
大きくなっていないのに、0.8mmの段差とすることによ
り顕著にこれらの値が上昇することがわかる。According to the inventor's pull-out test and bending strength test of the connecting portion, the embossed steps 0.8 mm and 0.6 mm
When comparing 0.3 mm and 0.3 mm, the values of 0.3 mm and 0.6 mm for 0.6 mm are about 10% higher in both the pull-out test and the bending strength test than those of 0.3 mm. On the other hand, in the case of 0.6 mm and 0.8 mm, the value of 0.8 mm is about three times the value in the pull-out test and about twice the value in the bending strength test as compared with the 0.6 mm one. It can be seen that the difference in size between the 0.8 mm and 0.6 mm steps is only about 30%, but these values increase significantly when the 0.8 mm step is used.

連結する。Then, as shown in FIG. 3, the outer wall plate on the lower side is attached so that the waterproof portion 12 is attached upward, and the extension portion 11 is attached to the attachment surface 18 such as a pillar, a stud, a wall foundation, and a furring strip by a nail 17 or the like. Fix it. Then, the insertion portion 7 of the outer wall plate on the upper side is inserted into the insertion groove 10 of the lower outer wall plate, and the insertion portion 9 of the upper outer wall plate is inserted into the insertion groove 6 of the lower outer wall plate and is connected by dropping.
