Description

  The present invention relates to a metal exterior material having a metal surface material and a foamed resin layer, and a building exterior structure using the same.

  2. Description of the Related Art Conventionally, a metal exterior material in which a metal face material is used as a surface layer and a resin layer is disposed on the back surface thereof is known. For example, as shown in FIG. 6, the metal exterior material has various metal surface materials 1 made of aluminum, iron, or the like as a surface layer, and a foamed resin layer 2 is disposed on the back surface thereof. Further, an aluminum foil or a sheet 3 having a function equivalent to that of the aluminum foil is attached. As shown in FIG. 6, such a metal exterior material A is connected to other metal exterior materials B and C at the upper and lower positions by, for example, a ridge portion and a groove portion at the upper and lower ends in a laterally stretched structure. Wall surfaces and the like are formed.

  Metal exterior materials with foamed resin layer 2 on the back are lightweight and have good heat and fire resistance, insect proofing, moisture proofing, sound insulation, etc., and are used for the outer walls of residential buildings. Various devices for improvement have been promoted. For example, mixed ground charcoal of Bincho charcoal and white charcoal is placed on the back of the metal face material to remove moisture that causes mold, mites, etc., improving insect control and moisture resistance, and negative ion effect There has been proposed a metal exterior material that aims to achieve the above (Patent Document 1).

  However, with regard to conventional metal exterior materials, studies on adding various functions such as insect repellent properties have not progressed much.

  On the other hand, various attempts have been made to impart functionality to members and parts constituting a building. For example, a sound generator speaker is mounted on an aluminum sash frame to make a mosquito sash (Patent Document 2), or a vibration generation source is provided in the underfloor structure to transmit vibration sound to the underfloor structure to remove white ants. Repelling (Patent Documents 3 and 4) is known.

However, in the case of these conventional examples, all provide functionality such as insect repellent at a specific part of the building, and the degree of freedom in selecting a part in the building for providing functionality is low. Since the speaker and the vibration source are mounted in a state of protruding from the member, there is a problem that the design and construction restrictions are large.
