  However, in the finished structure obtained by the above construction method, it is difficult to have a sense of unity with other parts at the corner where the parting material and gasket exist, and this becomes a bottleneck in improving the design. There's a problem.

  The present invention has been made in consideration of the above-mentioned matters, and the purpose thereof is to use a corner spandrel that facilitates making the corner portion such as a wall or ceiling have a sense of unity with other portions, and the same. It is to provide a finishing structure.

  In order to achieve the above object, a corner spandrel according to the present invention includes a bent main body portion and engaging portions that are provided at both ends of the bent main body portion and engage with different span drels, respectively. The main body includes a corrugated portion that protrudes forward, and the corrugated portion is formed in a corrugated shape in which the traveling direction changes between the corrugated portions (claim 1).

  On the other hand, in order to achieve the above object, a finishing structure according to the present invention comprises the corner spandrel according to claim 1 and a straight spandrel. The straight spandrel includes a rectilinear main body portion and the rectilinear main body. The main body portion includes engagement portions that are provided at both ends of the main body portion and engage with different spandrels, and the rectilinear main body portion includes a corrugated portion that protrudes forward, and the corrugated portion is in the middle in the traveling direction. The left and right end portions of the corrugated portion of the bent main body portion of the corner spandrel have the same shape as the left and right end portions of the corrugated portion of the rectilinear main body portion. 2).

  The finishing structure includes a plurality of straight spandrels having different corrugated portions, and a left end portion of the corrugated portion of the bent main portion of the corner spandrels includes a plurality of the rectilinear body portions. Any one of the corrugated portions has the same shape as the left end portion of the corrugated portion, and the right end portion of the corrugated body portion of the corner spandrel has the corrugated portion of the straight main body portion. It may be the same shape as the right end of the mold part.

  In the finishing structure, the straight spandrel may be provided along one of two adjacent sides at the opening edge of the building, and the corner spandrel may be provided along the other.

  In the present invention, it is possible to obtain a corner spandrel and a finished structure using the same, which make it easy to provide a corner portion such as a wall or a ceiling with a sense of unity with other portions.

  That is, in the corner spandrel according to the first aspect of the present invention and the finishing structure according to the second aspect of the present invention, there is no need to use a parting material or the like for the corner portion such as a wall or ceiling, and a three-dimensional design using the spandrel. Can be realized.

  In the finishing structure of the invention according to claim 3, by using a plurality of types of straight spandrels, the design of the finishing structure can be varied.

  In the finishing structure of the invention according to claim 4, it is easy to give continuity to the spandrel existing at the opening edge of the building and to give the corner portion formed at the opening edge a sense of unity with other parts. Become.

(A)-(C) are explanatory drawings which show roughly the structure of the 2 types of straight spandrel used for the finishing structure which concerns on one embodiment of this invention, and a kind of spandrel for corners. (A) And (B) is the front view and cross-sectional view which show the structure of the principal part of the said finishing structure roughly. It is explanatory drawing which shows schematically the structure of the said span spandrel for corners. (A) And (B) is the front view and cross-sectional view which show schematically the structure of the principal part of the building which has the opening edge to which the said finishing structure is applied.

  Embodiments of the present invention will be described below with reference to the drawings.

  The finishing structure according to the present embodiment includes two types of straight spandrels A and B that are randomly arranged on the straight portion of the finished surface (outer wall, inner wall, ceiling, etc.) and a kind of corner that is arranged on the corner portion. And a spandrel C (see FIGS. 1A to 1C, FIGS. 2A and 2B). In addition, the finishing structure of this example provides spandrel AC as a double skin outside the wall which forms a water stop line, and is applicable also to the repair plan of the existing building.

  The spandrels A to C are made of, for example, an aluminum extrusion mold. As shown in FIGS. 1A to 1C, the spandrels A to C are provided at both ends of the main body 2 and the main body 2, respectively. And an engaging portion 3 to be joined.

  The body part 2 of the straight spandrels A and B is a straight traveling body including a corrugated portion that is formed in a wave shape that protrudes forward and does not change its traveling direction in the middle (the front end of each wave is located on the same plane). Whereas the main body 2 of the corner spandrel C protrudes forward, the traveling direction changes in the middle (the front ends of the waves are not located on the same plane). It is configured as a bent main body portion 2C including a corrugated portion formed in a wave shape.

  Here, although the shape of the corrugated portion of the two types of rectilinear main body portions 2A and 2B is different from each other, the adjacent main body portions 2 (straight-axis main body portion 2A) even if the two types of straight spandrels A and B are arranged randomly , 2B) is configured such that continuity is maintained at the boundary of the corrugated portion (the wave does not break).

  On the other hand, the engagement part 3 of each spandrel A to C includes a male part 4 formed on one end side of the main body part 2 and a female part 5 formed on the other end side of the main body part 2. 4 and the female part 5 are formed so as to engage with the female part 5 and the male part 4 of the adjacent spandrels A to C, respectively.

  Further, the main body portion (curved main body portion 2C) 2 of the corner spandrel C has a substrate portion 6 that covers the back surface of the corrugated portion, and the substrate portion 6 is bent or curved at an intermediate portion in the longitudinal direction thereof. The middle part is connected to the middle part of the corrugated part.

  Further, the left end portion of the corrugated portion of the curved main body portion 2C of the corner spandrel C has the same shape as the left end portion of any one of the straight main body portions 2A and 2B. The right end portion of the corrugated portion of the portion 2C has the same shape as the right end portion of one of the straight traveling main body portions 2A and 2B. In this example, as shown in FIG. 3, the left side of the corrugated portion of the bent main body 2C of the corner spandrel C has the same shape as the left side of the corrugated portion of the rectilinear main body 2B. The right side portion of the corrugated portion of the curved main body portion 2C has the same shape as the right side portion of the corrugated portion of the rectilinear main body portion 2A, and the left side portion of the corrugated portion of the main body portion 2C of the corner spandrel C The right side portions are configured so as to be smoothly connected to each other (so that no step is formed), and their extending directions are different from each other (in this example, orthogonal).

  As described above, the corrugated portions of the two types of rectilinear main body portions 2A and 2B are adjacent to the adjacent main body portions 2 (straight rectilinear main body portions 2A and 2B) even if the two straight spandrels A and B are arranged randomly. Since continuity is maintained at the boundary of the corrugated part, the same continuity is maintained between the corner spandrel C and the spandrels A and B connected to the left and right. Become.

  In the finishing structure of this example, the use of the corner spandrel C configured as described above eliminates the need to use a parting material or the like in the corner portion such as a wall or ceiling, and realizes a three-dimensional design using the spandrel. It becomes possible. Further, by using two types of straight spandrels A and B, it is possible to give diversity to the design of the finished structure.

  FIGS. 4A and 4B show an example in which a finishing structure including spandrels A to C is provided on the outer wall of a building having an opening O that is opened and closed by a shutter, for example. In this example, spandrels A to C extending in the vertical direction are arranged from the wall W1 on the left side of the opening O to the wall W3 on the right side of the opening O through the hanging wall W2 positioned above the opening O. Here, the corner spandrel C is provided only in the portions located on the left and right edges of the opening O, and two types of straight spandrels A and B are randomly arranged in the other portions. That is, the straight spandrels A and B are provided so as to be orthogonal to the direction in which the side extends along one side (the upper side in the example of FIG. 4A) of the two adjacent sides at the opening edge of the building. A corner spandrel C is provided so as to be parallel to the direction in which the side extends along the left and right sides in the example of FIG. In addition, the broken line in FIG.4 (B) shows spandrel A, B provided in the drooping wall W2.

  Thus, by providing spandrel A to C, the spandrel A to C existing at the opening edge of the building has continuity, and the corner formed at the opening edge has a sense of unity with other parts. It becomes easy.

  In addition, this invention is not limited to said embodiment at all, Of course, it can change and implement variously in the range which does not deviate from the summary of this invention. For example, the following modifications can be given.

  In the above-described embodiment, two types of straight spandrels A and B and one type of corner spandrel C are used, but not limited to this, three or more types of straight spandrels and two or more types of corner spandrels are used. You may do it.

  The wave shapes of the corrugated portions of the spandrels A to C are not limited to random ones, and may be waves having regularity such as rectangular waves and sine waves.

  In the above embodiment, the substrate portion 6 is provided only on the corner spandrel C, but the substrate portion may be provided on one or both of the straight spandrels A and B. However, the substrate portions provided on the straight spandrels A and B do not need to be bent or curved at the intermediate portion in the longitudinal direction as the substrate portion 6 does.

  The corner spandrel C of the above embodiment is configured so as to be suitable for a corner portion having a corner angle (an angle formed by two surfaces forming the corner portion) of 90 °. The corner spandrel C may be configured so as to be suitable for the included corner portion. For example, the corner spandrel C may be configured to be used not in the protruding corner portion but in the entering corner portion. Further, the substrate portion 6 may not be provided.

  In the example shown in FIG. 4 (A), the spandrels A to C are used upright (in a substantially vertical direction) on the inner wall of the building. In this way, the span drels A to C are used on the inner wall and the outer wall of the building. The spandrels A to C may be laid sideways (substantially in the horizontal direction). However, in particular, when the spandrels A to C are used for the outer wall, it is desirable that a portion in which rainwater or the like is accumulated is not formed in the corrugated portion of the span drels A to C. Of course, the spandrels A to C can be used not only for the inner wall and the outer wall of the building but also for the ceiling and the like.

  Needless to say, the above modifications may be combined as appropriate.
