Description

【０００１】
【発明の属する技術分野】
本発明は縦葺き或いは横葺きの屋根構造や壁構造として有用な外装構造に関する。
【０００２】
【従来の技術】
近年、建築物の外装構造として、隣接する縦葺外装材の接続部の屋内側に樋部材を添設する構造が多く提案されており、このような構造は、外装材の側縁部間の隙間からの侵入水を、外装面の屋内側に添設された樋部材で受け止めて軒側に排出するものである。しかしながら、風雨等により木の葉や枝、塵、埃等が外装面に頻繁に飛来してくるような環境の建築物では、経年の使用により侵入水とともに微細な木の葉や枝、塵、埃等が樋部材内に侵入し、排水面に堆積し、この堆積物が排水を妨げることがあった。
また、外装材間を隙間なく接続する方法として、シーム溶接が一般的に知られている。しかし、シーム溶接は、例えばステンレス板を溶接する場合、その溶接箇所はおよそ１５００℃程度になる。この高温により板の接合面を溶融して接合するのだが、同時に金属板がその高温で変形してしまうという問題が生じる。
このため、この方法で施工した金属板の屋根や壁は、溶接箇所を中心としてべコベコに変形してしまい、非常に美観を損ねていた。さらに、溶接部の組成が変化することにより、その部分から腐食し易くなってしまうという欠点もあった。
金属を溶融せずに隙間なく接続する方法として、特開平２０００‐３１４２１１号に「建築用材の接合構造」が提案されている。同構造は、金属薄板材に熱融着可能な合成樹脂フィルムを被覆した建築用材の側縁部同士を重合し、樹脂溶接により接合するものである。
詳述すると、前記樹脂溶接は、樹脂溶接機の溶接ホルダから溶融した樹脂を送り出し、溝状部分に溶融した樹脂を充填すると共に、合成樹脂フィルム部分を溶融接着するものである。このときの加熱温度は、使用する樹脂の種類にもよるが、およそ１００℃〜３００℃程度である。
しかし、同構造のものは、金属薄板の表面側にのみ合成樹脂フィルムを被覆しているので、経年変化により建築用材側縁部から合成樹脂フィルムが剥離する虞れがあった。また、樹脂溶接の樹脂で接続部の隙間を埋めることにより接続しているので、強固な接続とは言えなかった。また、樹脂溶接に於いて樹脂を均一に盛るには、樹脂の供給量と溶接ホルダの移動速度を一定にしなければならず、大型の機械を用いなければならなかった。さらに、樹脂溶接が万一不完全であった場合、直ちに建物内部への漏水へとつながる虞れがある等の問題点があった。
【０００３】
【発明が解決しようとする課題】
解決しようとする課題は、第１には、水密性そして美観に優れ、しかも施工作業を容易に行えて、工期の短縮及びコストの削減を図ることができる外装構造を、第２には、さらに、様々な外装面意匠に仕上げることができる外装構造を、第３には、さらに、対負圧強度が高い外装構造を、第４には、さらに、水密性が高い外装構造を、第５には、さらに、二重に排水能力を有して雨仕舞が高い外装構造を提供することにある。

BACKGROUND OF THE INVENTION
The present invention relates to an exterior structure useful as a vertical or horizontal roof structure or wall structure.
[0002]
[Prior art]
In recent years, many structures have been proposed as an exterior structure of a building, in which an eaves member is provided on the indoor side of a connecting portion of adjacent vertical eaves exterior materials, and such a structure is provided between the side edges of the exterior material. The intruding water from the gap is received by the eaves member attached to the indoor side of the exterior surface and discharged to the eaves side. However, in an environment where leaves, branches, dust, dust, etc. frequently fly to the exterior surface due to wind and rain, etc., fine tree leaves, branches, dust, dust, etc., together with intrusion water, are Intrusion into the member and accumulation on the drainage surface, and this deposit sometimes hinders drainage.
Further, seam welding is generally known as a method for connecting the exterior materials without gaps. However, in the seam welding, for example, when a stainless steel plate is welded, the welding location is about 1500 ° C. At this high temperature, the joining surfaces of the plates are melted and joined, but at the same time, the problem arises that the metal plates are deformed at the high temperatures.
For this reason, the roof and wall of the metal plate constructed by this method are deformed into a bevel around the welded part, which is very detrimental to the appearance. Furthermore, there has been a drawback in that the composition of the welded portion changes, and the portion tends to corrode.
As a method for connecting metals without melting without gaps, Japanese Patent Application Laid-Open No. 2000-314211 proposes a “joining structure for building materials”. In this structure, side edges of building materials coated with a synthetic resin film that can be heat-sealed to a metal thin plate material are polymerized and joined by resin welding.
More specifically, in the resin welding, molten resin is sent out from a welding holder of a resin welding machine, the molten resin is filled in the groove-shaped portion, and the synthetic resin film portion is melt-bonded. Although the heating temperature at this time is based on the kind of resin to be used, it is about 100 to 300 degreeC.
However, in the structure having the same structure, since the synthetic resin film is coated only on the surface side of the metal thin plate, there is a possibility that the synthetic resin film may be peeled off from the edge of the building material due to aging. Moreover, since it connected by filling up the clearance gap of a connection part with resin of resin welding, it could not be said that it was a firm connection. Further, in order to uniformly deposit the resin in the resin welding, it is necessary to make the supply amount of the resin and the moving speed of the welding holder constant, and it is necessary to use a large machine. Furthermore, in the unlikely event that the resin welding is incomplete, there is a problem that there is a possibility that water leaks into the building immediately.
[0003]
[Problems to be solved by the invention]
Problems to be solved are, firstly, an exterior structure that is excellent in water tightness and aesthetics, and that can easily perform the construction work, and can shorten the construction period and reduce the cost. The exterior structure that can be finished into various exterior surface designs, the third, the exterior structure having a higher resistance to negative pressure, the fourth, the exterior structure having a higher water tightness, the fifth Furthermore, it is to provide an exterior structure having a double drainage capacity and high rain performance.
[0004]
[Means for Solving the Problems]
In order to achieve the above-described problems, the present invention provides an exterior structure in which an exterior surface is formed by connecting a resin-coated exterior material coated with a synthetic resin to a metal plate material. The resin-coated exterior material is only a surface portion of the metal plate material. Is formed with a synthetic resin, and a connection part consisting of side edges coated with the synthetic resin is formed by folding or bending, and the synthetic resin at the connection part of the adjacent resin-coated exterior materials is connected to each other in a watertight state by fusion. And the connection part with the metal plate-material surface part and the adjacent resin coating | covering cladding | exterior_material is covered and formed by the said synthetic resin continuously, It is characterized by the above-mentioned.
In the present invention, the resin-coated exterior material is a decorative material covering a roof plate material or a wall plate material and side edge portions thereof.

And as a coating aspect of the metal board | plate material by the synthetic resin in a resin coating exterior material, it becomes the aspect which covered the resin coating exterior material which coat | covered only the surface part continuously to the back surface by shaping | molding, such as folding or bending. Specifically, only the surface portion of a flat metal plate material is covered with a synthetic resin, and one or two or more side edges of the upper, lower, left, and right side edges are folded or folded downward (synthesized by folding or folding) A side edge covered with a resin is formed), but at least a connection part between the surface portion of the metal plate material and the adjacent resin-coated exterior material may be continuously formed with a synthetic resin.
The metal plate covered with the synthetic resin may be a flat plate or a plate having an appropriate function and design such as irregularities. And the connection part currently coat-formed with the synthetic resin together with the metal plate surface part is an aspect that is a connection part of the side edge part bent to the back side in the flat plate or plate metal plate material, flat plate or plate Any of the aspect which is a connection part of the side edge part turned back to the back surface side in the shape-like metal plate material, and other aspects similar to these may be used. Moreover, the connection part is not limited to flat form, You may provide the shaping | molding part.
The connection by fusion of the connection parts includes connection by a surface contact portion that is performed at the overlapping portion of the surfaces or the surfaces. Connection by the surface contact portion is easier without requiring high accuracy for the fusion work. The fusing may be any fusing method such as heat fusing, ultrasonic fusing, high frequency fusing, etc., and also includes fusing that uses a solvent (adhesive) and is chemically melted and bonded. The synthetic resin coating on the metal plate material is formed by attaching a synthetic resin film to the metal plate material with an adhesive or the like, or by applying a thick film coating of the synthetic resin. As a coating method, any known method may be employed as long as a uniform film can be formed with a thickness that does not expose the underlying metal at the time of fusion. Further, the resin-coated exterior material may be formed by thickening the synthetic resin only at the part to be fused, that is, at the connection part.
The metal plate material may be a known metal material such as a stainless steel plate, an aluminum alloy plate, a titanium alloy plate, or a copper plate. Synthetic resins are polyethylene, polyolefin, polyurethane, polyvinyl chloride, etc., which can be fused at a heating temperature much lower than the welding temperature (eg, polyvinyl chloride: about 200 ° C.). Any known material may be used as long as it has elasticity and durability enough to follow. The method of attaching the resin-coated exterior material may be directly attached to the base with a screw or the like, a holding member such as a hanging member may be used, and any other known method may be used. The resin-coated exterior material may be formed with a flange on one or both side edges, and the shape of the flange may be any shape such as an inverted U shape, a U shape, or a V shape. Moreover, you may provide a collar member in the connection part lower surface of a resin coating | covering exterior material. The exterior structure is not limited at all, for example, another exterior material may be provided on the upper surface side to form a double-glazed structure, or a greening device may be provided to form a green roof.
When the decorative material is a cover material that covers between the side edges of the roof plate material or the wall plate material, the cross-sectional shape thereof may be a flat shape, a triangular shape, a quadrangular shape, a semicircular shape, or any other shape similar to these. The attachment of the resin-coated exterior material to the base by the holding member is not limited as long as it can withstand the negative pressure caused by blowing up. As with the resin-coated exterior material, the waterproof material may be a metal plate coated with a synthetic resin, a waterproof sheet of a synthetic resin alone, or an amorphous sealing material, etc. If there is no limitation. When the surface of the waterproof material is a synthetic resin, the connection with the resin-coated exterior material may be any fusion method such as thermal fusion, ultrasonic fusion, and high-frequency fusion, and a solvent (adhesive) is used. In addition, welding that is chemically melted and bonded is also included. The eaves member may have any shape, as long as water can be reliably discharged to the eaves.

【The invention's effect】
A. According to claim 1, the resin-coated sheathing material is formed by continuously covering at least the metal plate member surface portion and the adjacent resin-coated sheathing material with a synthetic resin and connecting the adjacent resin-coated sheathing materials. Since the synthetic resins are fused together, there is little risk of resin peeling due to changes over time, and an exterior structure with excellent water tightness can be obtained.
Since the resin-coated exterior material is formed by continuously coating at least the surface portion of the metal plate material and the connecting portion with the adjacent resin-coated exterior material with synthetic resin, it is excellent in water tightness and basically described in the prior art. There is no need to secure the drainage by installing a gutter member on the indoor side of the connecting part of the adjacent exterior material as in the prior application, which reduces the number of parts and makes the construction work simple and easy. .
Since the synthetic resins at the connection portions of the adjacent resin-coated exterior materials are fused together, the connection is more surely strong as compared to the case where the connection is made through resin welding as in the prior application.
Since the synthetic resins of the adjacent resin-coated exterior materials are fused together, a thicker fused portion is formed compared to the case of a prior application in which one is fused with a synthetic resin and the other is fused with a metal plate. This will ensure a more secure connection. In addition, there is little risk of exposing the underlying metal during fusion.
Since the heating temperature is much lower than that of welding, there is almost no deformation of the metal plate due to heating during connection.
When a solvent is used, there is no deformation due to heating.
The rapid temperature change is alleviated by the synthetic resin, and the amount of thermal expansion and contraction of the entire exterior material is alleviated.
Even if thermal expansion and contraction occurs due to changes in temperature, the deformation of the core metal plate can be absorbed by the external synthetic resin portion.
When all the metal plate material, that is, the end portion is covered with the synthetic resin, there is little possibility that the hand is cut at the end portion or the like during the operation.
B. According to the second aspect of the present invention, various exterior surface design exterior structures can be obtained by selecting the shape and color of the cover material.
C. According to the third aspect of the present invention, an exterior structure that is particularly excellent in strength against negative pressure can be obtained by further fitting the resin-coated exterior material to the fitting holding member.
D. According to the fourth aspect of the present invention, an exterior structure with excellent water tightness can be obtained.
E. According to the fifth aspect, the rain performance is ensured even if local damage occurs in the fused portion or there is a poorly constructed portion due to use over time. For example, in a green roof where trees are installed on the roof, when a fixing device for fixing the trees is provided on the resin-coated exterior material, the resin-coated exterior material is pierced with a fixing tool such as a screw and waterproofed by a waterproof seal, etc. Although the water-stop seal deteriorates due to secular change and the waterproof performance is reduced, if the collar member is arranged, even if the water-stop seal deteriorates, intrusion water can be easily removed. Can treat waste water.
