[First Embodiment]
As shown in FIGS. 1 and 2, the projected corner member 1 according to the first embodiment is arranged at the projected corner portion formed by the pair of wall members 2. The pair of wall materials 2 are arranged between the pillar material 6 as a skeleton in the building via a ventilation layer having thicknesses L1 and L2. A plurality of furring strips 4 as base materials are arranged on the ventilation layer. The furring strip 4 is fixed to the pillar member 6 by a fixing tool such as a nail or a screw. The wall material 2 is fixed to the furring strip 4 via the ventilation fitting 31.

As shown in FIG. 2, the protruding corner portion is formed by arranging a pair of adjacent side end faces 2a of the pair of wall materials 2 so as to form a predetermined angle. The pair of side end faces 2a are adjacent to each other without abutting against each other's back surfaces 2b. The pair of side end faces 2a are adjacent to each other with a predetermined interval without contacting the adjacent ends. The pair of side end faces 2a form a predetermined angle according to the shape of the skeleton. In the present embodiment, the pair of side end faces 2a are adjacent to each other at an angle of approximately 90 degrees in a concave shape in the direction of the pillar member 6.

The protruding corner member 1 is arranged so as to extend in the vertical direction so as to cover the pair of side end surfaces 2a at the protruding corner portion. The protruding corner member 1 is, for example, a long member made of a single member. As shown in FIG. 2, the protruding corner member 1 has first surfaces 13a and 13b, second surfaces 12a and 12b, and guide pieces 14a and 14b. The first surfaces 13a and 13b are continuous via the bent portion 15, and the bent portions 11a and 11b are provided at the tips of the second surfaces 12a and 12b. The protruding corner member 1 has a symmetrical structure in the cross section. The material constituting the projected corner member 1 is not particularly limited, and a known material used for the exterior of the building can be used.

The first surfaces 13a and 13b are surfaces arranged so as to face the pair of side end surfaces 2a, respectively. The first surfaces 13a and 13b are continuous at an angle similar to the angle formed by the pair of side end surfaces 2a via the bent portion 15. In the present embodiment, the first surfaces 13a and 13b are continuous at an angle of approximately 90 degrees. The ends of the first surfaces 13a and 13b in the building outer direction are continuous with the guide pieces 14a and 14b, respectively.

The first surfaces 13a and 13b extend from the side end surface 2a side to the ventilation layer side having the thicknesses L1 and L2 where the furring strip 4 is arranged and continue. The first surfaces 13a and 13b are used as a base material to be arranged in the ventilation layer from a position facing the end of the side end surface 2a in the building outer direction to a position facing the end of the side end surface 2a in the building inner direction. It extends to a position facing the side end surface of the furring strip 4 and continues. In the present specification, "opposing" includes a case where there is a certain distance between the surfaces and a case where the surfaces are in contact with each other without a space. As described above, the first surfaces 13a and 13b extend to the ventilation layer side and are continuous, so that the thickness of the wall material 2 is thicker than the length in the width direction of the side end surface 2a corresponding to the actual thickness of the wall material 2. It is visually recognized. The thickness of the wall material 2 is visually recognized as if it is the same thickness as the length of the first surfaces 13a and 13b in the width direction.

The second surfaces 12a and 12b are surfaces arranged so as to face each other of the pair of back surfaces 2b of the pair of wall materials 2. The second surfaces 12a and 12b are arranged at a predetermined distance from the pair of wall materials 2. The second surfaces 12a and 12b are arranged in contact with the furring strip 4. The second surfaces 12a and 12b may be fixed to the furring strip 4. Bent portions 11a and 11b are provided on the tip ends of the second surfaces 12a and 12b. The base end side of the second surfaces 12a and 12b is continuous with the first surfaces 13a and 13b.

The bent portions 11a and 11b are provided on the tip end side of the second surface 12a and 12b. The bent portions 11a and 11b are continuous with the second surfaces 12a and 12b and are bent substantially perpendicular to the second surfaces 12a and 12b in the direction of the wall material 2. By providing the bent portions 11a and 11b, spaces S1 and S2 are formed between the wall material 2 and the second surfaces 12a and 12b. The distance between the second surfaces 12a and 12b and the wall material 2, which is the bending length of the bent portions 11a and 11b extending in the direction of the wall material 2, is substantially equal to the thickness of the ventilation fitting 31. Therefore, the ventilation fitting 31 can be arranged in the spaces S1 and S2.

The tips of the bent portions 11a and 11b come into contact with the back surface 2b of the wall material 2. Moisture such as rainwater or moisture may enter the back surface 2b side from the front surface side of the wall material 2 through the gap between the wall material 2 and the guide pieces 14a and 14b. However, the invaded moisture is blocked by the bent portions 11a and 11b and flows downward without reaching the skeleton side including the column member 6.

The guide pieces 14a and 14b are formed by bending the ends of the first surfaces 13a and 13b in the building outer direction substantially perpendicularly to the wall material 2 directions. The guide pieces 14a and 14b are arranged so as to face the surfaces of the pair of wall materials 2. The guide pieces 14a and 14b regulate the arrangement of the wall material 2, and the wall material 2 can be easily positioned. The guide pieces 14a and 14b completely cover the pair of side end faces 2a so as not to be visible from the outside.

(Manufacturing method of protruding corner member)
The method for manufacturing the protruding corner member 1 is not particularly limited, but it can be manufactured, for example, by bending a single rectangular metal plate. The protruding corner member 1 can be manufactured, for example, by the following procedure. First, the metal plate is folded back at an angle of 180 ° to form the bent portion 11a. Next, the metal plate is bent at an angle of 90 ° from the folded portion to form the second surface 12a. Next, the metal plate is bent at an arbitrary position at an angle of 90 ° to form a part of the first surface 13a. Next, the metal plate is bent at an arbitrary position at an angle of 90 ° and folded back at an arbitrary position at an angle of 180 ° to form the guide piece 14a. Next, in order to form the guide piece 14a, the metal plate is bent at an angle of 90 ° from a portion bent at an angle of 90 ° to form the first surface 13a. Next, the metal plate is bent at the bent portion 15 at an angle of 90 ° to form the first surface 13b. In the same procedure, the guide piece 14b, a part of the first surface 13b, the second surface 12b, and the bent portion 11b are formed. In order to improve the weather resistance, corrosion resistance, and designability of the manufactured projected corner member 1, the surface treatment or coating may be performed with a known material.

The wall material 2 constitutes the outer wall of the building. The wall material 2 is not particularly limited, but is, for example, a panel-shaped outer wall material. As the wall material 2, for example, a ceramic siding material or a metal siding material is used.

The ventilation fitting 31 fixes the wall material 2 to the furring strip 4. The ventilation fitting 31 can be engaged with the wall material 2, and one or more fixing holes 31a are provided on the front surface. The wall material 2 can be fixed to the furring strip 4 by engaging the ventilation fitting 31 with the wall material 2 and inserting a fixing tool such as a screw or a screw through the fixing hole 31a to fix it to the furring strip 4. The ventilation fitting 31 and the heads such as screws and screws that are a part of the fixing tool are arranged in the spaces S1 and S2 provided between the wall material 2 and the furring strip 4. The thickness of the ventilation fitting 31 is, for example, about 5 mm.

The furring strip 4 as a base material fixes the wall material 2 to a skeleton such as a pillar material 6. In the present embodiment, the furring strip 4 is a vertical furring strip that is attached perpendicularly to a skeleton such as a pillar member 6. As shown in FIG. 2, the furring strip 4 and the ventilation fitting 31 form a ventilation layer having thicknesses L1 and L2 between the wall material 2 and the pillar material 6. With the above-mentioned ventilation layer, the ventilation of the building can be ensured, and deterioration due to internal dew condensation and water absorption of the wall material 2 can be suppressed.

According to the protruding corner member 1 according to the first embodiment, the following effects are achieved. The protruding corner member 1 is arranged between the protruding corner member 1 and the pillar member 6 as a skeleton via a ventilation layer, and is formed by a pair of wall members 2 having a pair of side end faces 2a adjacent to each other and forming a predetermined angle. In addition, it is assumed that they are arranged so as to extend in the vertical direction so as to cover the pair of side end faces 2a. The protruding corner member 1 is arranged so as to face the pair of side end faces 2a, and extends from a position facing the end of the pair of side end faces 2a in the building outer direction to a position facing the ventilation layer to form a predetermined angle. It is assumed that it has a pair of continuous first surfaces 13a and 13b. From the above, it is recognized that the thickness of the wall material 2 is thicker than the length in the width direction of the side end surface 2a corresponding to the actual thickness of the wall material 2 and is similar to the length in the width direction of the first surfaces 13a and 13b. To. In addition to the above, the protruding corners can be compactly configured by covering the pair of side end surfaces 2a adjacent to each other at a predetermined angle with the continuous first surfaces 13a and 13b at a predetermined angle. As a result, a preferable design property of the protruding corner portion on which the protruding corner member 1 is arranged can be obtained.

The protruding corner member 1 has a pair of second surfaces 12a and 12b arranged so as to face the back surfaces 2b of the pair of wall materials 2, respectively, and the pair of second surfaces 12a and 12b have the wall material 2 on the tip side. It is assumed that the bent portions 11a and 11b are in contact with the back surface 2b of the above. As a result, the moisture that enters through the gap between the protruding corner member and the wall material 2 is blocked by the bent portions 11a and 11b, so that it is prevented from entering the ventilation layer. Therefore, a waterproof effect can be obtained on the skeleton side including the pillar member 6 of the building. Therefore, waterproofing with a sealing material or the like can be omitted or minimized. In addition to the above, the bending length of the bent portions 11a and 11b extending in the direction of the wall material 2 can be adjusted to the same length as the thickness of the ventilation fitting 31. As described above, the ventilation fitting 31 having a desired thickness can be arranged between the furring strip 4 as the base material and the wall material 2.

The protruding corner member 1 is made of a single member. As described above, since the protruding corner member 1 can be configured without a gap, a waterproof effect on the skeleton side including the pillar member 6 of the building can be obtained. Further, the cost related to the manufacture of the protruding corner member 1 can be reduced.

Like the ventilation fitting 31, the ventilation fitting 32 can be engaged with the wall material 2, and one or more fixing holes 32a are provided on the front surface thereof. The wall material 2 can be fixed to the pillar material 6 by engaging the ventilation metal fitting 32 with the wall material 2 and inserting a fixing tool such as a screw or a screw through the fixing hole 32a to fix the wall material 2 to the pillar material 6. The thickness of the ventilation fitting 32 is thicker than the thickness of the ventilation fitting 31, for example, about 15 mm. The ventilation fitting 32 can form a ventilation layer having a sufficient thickness without providing a furring strip between the skeleton and the wall material 2.

The spacer 5 as a base material is arranged in a ventilation layer formed between the wall material 2 and the pillar material 6. The spacer 5 is used as a base when fixing the wall material 2 to the pillar material 6 by using the ventilation fitting 32. The spacer 5 is, for example, a member extending in the vertical direction, and is fixed in contact with the pillar member 6. The total of the thickness of the spacer 5 and the thicknesses of the bent portions 11a and 11b is the same as the thickness of the ventilation fitting 32. Therefore, by fixing the spacer 5 to the pillar material 6 and arranging the wall material 2 after arranging the protruding corner member 1, a space for arranging the ventilation fitting 32 is secured between the pillar material 6 and the wall material 2. it can.

The first surfaces 13a and 13b are ventilation layers having thicknesses L1 and L2, respectively, from a position facing the end of the side end surface 2a in the building outer direction to a position facing the end of the side end surface 2a in the building inner direction. It extends to the position facing the and continues. The bent portion 15 is arranged so as to be closer to the pillar member 6 than in the case of the first embodiment. The protruding corner member 1 can be arranged at the protruding corner by adjusting the distance between the bent portion 15 and the skeleton even when the thicknesses L1 and L2 of the ventilation layer of the building are slightly different.

As described in the first embodiment and the second embodiment, the protruding corner member 1 has bent portions 11a and 11b. As a result, the ventilation layer can be formed by combining the ventilation fitting 31 having the same thickness as the bending length of the bending portions 11a and 11b and the furring strip 4. At the same time, the ventilation layer can be formed by the ventilation fitting 32 having an arbitrary thickness.

The preferred embodiments of the present disclosure have been described above. However, the present disclosure is not limited to the above embodiment, and can be changed as appropriate.

The protruding corner member 1 according to the above embodiment has been described as having a symmetrical structure in a cross section. However, it is not limited to this. The structure of the protruding corner member 1 may be an asymmetric structure. For example, when the configurations such as the thickness of the adjacent wall material and the ventilation layer constituting the projected corner portion are different, the configuration of the projected corner member 1 may be changed accordingly to obtain the projected corner member 1 having an asymmetric structure.

The protruding corner member 1 made of a single member according to the above embodiment has been described as being manufactured by bending a metal plate. However, it is not limited to this. The protruding corner member 1 made of a single member may be manufactured by another method such as welding. The bent portions 11a and 11b, the guide pieces 14a and 14b, and a part of the first surfaces 13a and 13b of the protruding corner member 1 are formed to be thicker than other portions by bending, but other parts such as welding and the like are formed.
