Abstract

<P>PROBLEM TO BE SOLVED: To provide an accessory outer facing material, hardly causing breakage of two outer facing pieces constituting the accessory outer facing material even if the bed of a building is deformed due to aging or an earthquake, and having good appearance. <P>SOLUTION: The inclined faces 1a, 2a of first and second outer facing pieces 1, 2 are coupled to each other through an elastic bonding raw material 3. In the first and second outer facing pieces 1, 2, the tip parts 1t, 2t where the inclined faces 1a, 2a and the surfaces 1s, 2s intersect make an acute angle. The elastic bonding raw material 3 is not extended to the tip parts 1t, 2t, so that a gap 12 is formed between the tip parts 1t, 2t. Therefore, the outer facing pieces 1, 2 follow up the deformation of the building, so that even if the tip parts 1t, 2t approach each other, the tip parts 1t, 2t are not subjected to stress by the elastic bonding raw material 3 to prevent damage to the tip parts 1t, 2t. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention provides an L-shaped accessory exterior in which a flat first exterior piece and a second exterior piece are joined together by an elastic adhesive material so that the plate surfaces of the exterior pieces are substantially perpendicular to each other. Regarding materials.

  As an L-shaped accessory exterior material to be constructed at the corners and corners of a building, there are two flat tiles joined with an epoxy adhesive, but the joint is rigid. The accessory exterior material is easy to break.

Japanese Patent Application Laid-Open No. 7-207813 discloses an accessory tile in which one side surface of a tile piece is inclined with respect to a plate surface, and the entire inclined surfaces of the two tile pieces are bonded to each other with an elastic adhesive. Is described. Since the accessory tile of the publication uses an elastic adhesive and the joint portion of the tile pieces has flexibility, the building frame is adjusted while adjusting the angle between the tile pieces of the accessory tile. It can be attached to the protruding corner. Further, paragraph 0016 of the same publication discloses that the tile pieces are not in direct contact with each other on the inclined surface, so that the loss is prevented.
Japanese Patent Application Laid-Open No. 7-207813

  In the above-mentioned accessory tile disclosed in Japanese Patent Application Laid-Open No. 7-207813, the inclined surfaces of the tile pieces are bonded to each other by an elastic adhesive. For this reason, when an external force is applied in the direction of narrowing the distance between the tip sides of the joints between the tile pieces, the amount of deformation of the elastic adhesive is small, and the deformation stress is applied to each tile piece tip side near the joints. Is easy to concentrate. Therefore, when the foundation of the building is greatly deformed due to aging or an earthquake, the tip side of the tile piece may be damaged.

  Further, in the accessory tile of the same publication, when an external force is applied so as to narrow the interval between the inclined surfaces, the elastic adhesive between the inclined surfaces is pressed and protrudes to the surface side, which impairs the beauty. There is also a fear.

  It is an object of the present invention to provide an accessory exterior material that is less likely to break the two exterior pieces constituting the accessory exterior material even when the foundation of the building is deformed due to aging, earthquake, or the like, and is excellent in beauty. Objective.

  The accessory packaging material according to claim 1 is an L-shaped accessory having an L-shaped corner portion in which the first exterior piece and the second exterior piece are joined so that the exterior pieces are substantially perpendicular to each other. It is an exterior material, and one side surface of the first and second exterior pieces is an inclined surface that obliquely crosses the front or back surface of the exterior piece, and the inclined surfaces are coupled to each other via an elastic adhesive material. In the accessory packaging material thus formed, the elastic adhesive material is not arranged up to the side of the convex corner portion of the L-shaped corner portion of the inclined surface. A gap is formed between the inclined surface of the exterior piece and the inclined surface of the second exterior piece.

  The accessory packaging material according to claim 2 is the depth of the gap when the length from the side on the convex corner portion side to the side opposite to the convex corner portion is L in claim 1. The length D is 0.5 mm or more and L / 2 or less.

  The accessory packaging material according to claim 3 is characterized in that, in claim 1 or 2, the width W of the gap is not less than 0.1 mm and not more than 2.0 mm.

  The accessory exterior material according to claim 4 is the tip portion according to any one of claims 1 to 3, wherein the first and second exterior pieces intersect at an acute angle between the inclined surface and the surface of the exterior piece. Is characterized by being chamfered.

  According to the accessory packaging material of the present invention, the gap is formed between the inclined surfaces on the convex corner portion side of the inclined surface. For this reason, when an external force is applied to the accessory exterior material so as to reduce the interval between the convex surfaces of the inclined surfaces, the elastic adhesive material between the inclined surfaces easily deforms following the external force. As a result, the stress generated in each exterior piece is relieved, and damage to the exterior piece is prevented. Further, since the gap exists, even if the elastic adhesive material is pressed and moved to the surface side, it is prevented from protruding from the gap.

  In the present invention, when the depth D of the gap is 0.5 mm or more, damage to the exterior piece and protrusion of the elastic adhesive material are more reliably prevented, and the elastic adhesive material is inconspicuous. When the depth D of the gap is L / 2 or less, the bonding force of the first and second exterior pieces by the elastic adhesive material is sufficient.

  In the present invention, when the width W of the gap is 0.1 mm or more, even if a large external force is applied to the accessory exterior material, these inclined surfaces do not contact and be damaged. Moreover, when the width W of the gap is 2.0 mm or less, the aesthetic appearance is excellent.

  In the present invention, it is preferable that the first and second exterior pieces have chamfered tip portions where the inclined surface and the plate surface intersect at an acute angle. In this case, it is possible to prevent injury when the human body touches the tip. Further, the tip portion is not easily damaged.
