[0013] Hereinafter, a building structure employing a corner member as a steel plate accessory according to one embodiment of the present invention will be described with reference to FIG.

[0014] The building structure 100 in this embodiment includes a skeleton 101, which is the structural component of the building, an eaves soffit material 102, four eaves soffit ventilation members 103 attached to the outer periphery of the eaves soffit material 102, and four corner members 1 installed at the corners of the building. The eaves soffit ventilation members 103 are members for ventilating the attic. The corner members 1 cover the ends of two adjacent eaves soffit ventilation members 103, connecting them together.

[0015] Next, the corner member 1 will be described below with reference to FIGS. 2 to 6. The corner member 1 (steel plate accessory) is manufactured by folding and assembling a single steel plate 90 (see FIG. 6). The steel plate 90 is formed by punching out a steel plate such as a stainless steel plate, a Galtite (registered trademark) steel plate, or a Galvalume (registered trademark) steel plate. As shown in FIG. 2, the corner member 1 is configured such that an end of one soffit ventilation member 103a is inserted from one side and an end of another soffit ventilation member 103b adjacent to the first soffit ventilation member 103a is inserted from the other side, thereby connecting and covering the ends of the two adjacent soffit ventilation members 103a, 103b. In this way, the corner member 1 is installed at the corner of a building.

[0016] The corner member 1 is divided into a left base portion 10L and a right base portion 10R shown in FIGS. 2, 3, and 5 by bending the steel plate 90 along a bending line 80 of the steel plate 90 shown in FIG. 6. The left base portion 10L shown in FIG. 2 is a portion in which a portion 50L (second portion) to the left of the bending line 80 of the steel plate 90 shown in FIG. 6 is formed into a generally U-shaped cross section that opens upward, as shown in FIG. 4. Thus, the left base portion 10L also corresponds to the "second portion" of the present invention. The right base portion 10R shown in FIG. 2 is a portion in which a portion 50R (first portion) to the right of the bending line 80 of the steel plate 90 shown in FIG. 6 is formed into a generally U-shaped cross section that opens upward. Thus, the right base portion 10R also corresponds to the "first portion" of the present invention. Then, each of the molded bases 10L, 10R is folded along the folding line 80 so that one side 50La (first side) of the periphery of the left portion 50L and one side 50Ra of the periphery of the right portion 50L shown in Figure 6 are aligned, thereby assembling the corner member 1. One ends of the sides 50La and 50Ra are connected to each other and also to the folding line 80. The method of assembling the corner member 1 will be described in detail later.

[0017] As shown in FIGS. 2 and 3, the base 10L has a bottom portion 11L, two folded portions 12L and 13L, a folded-back piece 14L, an overlapping piece 15L, and a guide piece 16L. As shown in FIG. 4, the bottom portion 11L has a horizontal bottom portion 11L1, a first inclined bottom portion 11L2, and a second inclined bottom portion 11L3. The horizontal bottom portion 11L1 extends horizontally. The first inclined bottom portion 11L2 is connected to the left end of the horizontal bottom portion 11L1 in FIG. 4 and is inclined upward. The second inclined bottom portion 11L3 is connected to the right end of the horizontal bottom portion 11L1 in FIG. 4 and is inclined upward. The horizontal bottom 11L1, the first inclined bottom 11L2, and the second inclined bottom 11L3 correspond, in order, to the regions 51L1 to 51L3 defined by the bending lines 81 to 84 in the left portion 50L of the steel plate 90 shown in Figure 6, and are formed by folding the left portion 50L along the bending lines 81 to 84.

[0018] As shown in Fig. 4(a), the bent portion 12L is bent from the left end of the bottom portion 11L so as to be positioned on the first inclined bottom portion 11L2. The bent portion 12L corresponds to the region 52L of the steel plate 90 shown in Fig. 6, and is formed by a valley fold along the bending line 83.

[0019] As shown in Fig. 4(a), the bent portion 13L is bent from the right end of the bottom portion 11L so as to be positioned on the second inclined bottom portion 11L3. The bent portion 13L corresponds to the region 53L of the steel plate 90 shown in Fig. 6, and is formed by a valley fold along the bending line 84.

[0020] As shown in FIG. 4(b), the folded piece 14L (engagement piece) is folded back from the right end of the bottom portion 11L so as to be positioned on the second inclined bottom portion 11L3. The folded piece 14L corresponds to the region 54L protruding from one side 50Lb (second side) of the periphery of the left portion 50L of the steel plate 90 shown in FIG. 6, and is configured by being valley-folded along the folding line 85. The folded piece 14L is configured so that its protruding length is longer than its connecting length with the side 50Lb. The side 50Lb is a side that continues to the other end (the end opposite the folding line 80) of the side 50La of the periphery of the left portion 50L.

[0021] 2 and 3, the overlapping filter piece 15L protrudes from the end of the bottom portion 11L on the base portion 10R side. More specifically, the overlapping filter piece 15L protrudes from the end of the horizontal bottom portion 11L1 on the base portion 10R side, and is overlapped on the horizontal bottom portion 11R1 of the base portion 10R. The overlapping filter piece 15L corresponds to a region 55L protruding from one side 50La of the periphery of the left portion 50L of the steel plate 90 shown in FIG. 6.

[0022] As shown in FIG. 2, the guide piece 16L protrudes from the end of the bottom 11L farthest from the base 10R. The guide piece 16L corresponds to the region 56L protruding from one side 50Lc of the periphery of the left portion 50L of the steel plate 90 shown in FIG. 6, and is configured by a valley fold along the folding line 86. The outline of the guide piece 16L is formed to match the outline of a specific soffit ventilation material 103. This makes it possible to prevent the end of a different type of soffit ventilation material 103 from being erroneously inserted into the left base 10L. The guide piece 16L also makes it possible to prevent the soffit ventilation material 103 from rattling relative to the left base 10L.

[0023] 2 and 3, the base portion 10R also has a bottom portion 11R, two folded portions 12R and 13R, two overlapping pieces 14R and 15R, and a guide piece 16R, similar to the base portion 10L. The bottom portion 11R has a horizontal bottom portion 11R1 and first and second inclined bottom portions 11R2 and 11R3 that are connected to the horizontal bottom portion 11R1 and inclined upward. The horizontal bottom portion 11R1, the first inclined bottom portion 11R2, and the second inclined bottom portion 11R3 correspond, in order, to regions 51R1 to 51R3 defined by folding lines 91 to 96 in the right portion 50R of the steel plate 90 shown in FIG. 6. The right portion 50R is formed by valley folding along folding lines 91 to 95 and mountain folding along folding line 96.

[0024] 2 and 3, the bent portion 12R is formed by bending the end of the bottom portion 11R so as to be positioned on the first inclined bottom portion 11R2, similar to the bent portion 12L. The bent portion 12R corresponds to the region 52R of the steel plate 90 shown in FIG. 6, and is formed by a valley fold along the bending line 93.

[0025] 2 and 3, the bent portion 13R is formed by bending the end of the bottom portion 11L so as to be positioned on the second inclined bottom portion 11R3, similar to the bent portion 13L. The bent portion 13R corresponds to the region 53R of the steel plate 90 shown in FIG. 6, and is formed by a valley fold along the bending line 94.

[0026] As shown in Figures 2 and 3, the two overlapping filter pieces 14R, 15R protrude from the end of the bottom portion 11R on the base 10L side. More specifically, the overlapping filter piece 14R protrudes from the end of the second inclined bottom portion 11R3 on the base 10L side and is overlapped on the second inclined bottom portion 11R3 of the base 10L. The overlapping filter piece 15R protrudes from the end of the first inclined bottom portion 11R2 on the base 10L side and is overlapped on the first inclined bottom portion 11R2 of the base 10L. The two overlapping filter pieces 14R, 15R correspond to regions 54R, 55R protruding from one side 50Ra of the periphery of the right portion 50R of the steel plate 90 shown in Figure 6. The overlapping pieces 14R and 15R are arranged apart from each other along one side 50Ra, and the overlapping piece 15L can be arranged between the overlapping pieces 14R and 15R.

[0027] The overlapping piece 14R is provided with an engaging claw 14Ra. The engaging claw 14Ra extends from the periphery of the overlapping piece 14R and is overlapped on the second inclined bottom portion 11R3 of the base 10L. The engaging claw 14Ra corresponds to a region 54Ra extending from the periphery of the region 54R, which is a boundary between one side 50Ra of the right portion 50R of the steel plate 90 shown in FIG. 6 and a side 50Rb (second side) continuing from the other end of the side 50Ra. As shown in FIGS. 2 and 3, the folded piece 14L is folded back so as to sandwich the engaging claw 14Ra between the second inclined bottom portion 11R3 and the folded piece 14L, so that the engaging claw 14Ra abuts against the inner side of the fold of the folded piece 14L and engages with the folded piece 14L. The engaging claw 14Ra and the folded piece 14L are arranged on the other end side opposite to the one end connected to the folding line 80 (the portion where the left base portion 10L and the right base portion 10R are continuously connected) of the sides 50La, 50Ra.

[0028] As shown in FIG. 2, the guide piece 16R, like the guide piece 16L, protrudes from the end of the bottom 11R farthest from the base 10L. The guide piece 16R corresponds to the region 56R partially protruding from one side 50Rc of the periphery of the right portion 50R of the steel plate 90 shown in FIG. 6, and is configured by a valley fold along the folding line 97. The outer shape of the guide piece 16R is also formed to match the outer shape of the specified soffit ventilation material 103. This makes it possible to prevent the end of a different type of soffit ventilation material 103 from being erroneously inserted into the right-side base 10R. The guide piece 16R also makes it possible to prevent the soffit ventilation material 103 from rattling relative to the right-side base 10R.

[0029] Next, a method for assembling the corner member 1 will be described below. First, a steel plate 90 having the shape shown in Fig. 6 is formed from a single steel plate by punching. Next, a left portion 50L of the steel plate 90 is valley-folded along bending lines 81 to 84, and 86 to form the left base portion 10L shown in Fig. 7. Furthermore, a right portion 50R of the steel plate 90 is valley-folded along bending lines 91 to 95, and 97, and mountain-folded along bending line 96 to form the right base portion 10R shown in Fig. 7.

[0030] Next, the steel plate 90 is folded along the folding line 80 to align one side 50La of the left portion 50L (left base portion 10L) shown in FIG. 6 with one side 50Ra of the right portion 50R (right base portion 10R) (folding process). At this time, as shown in FIG. 7, the overlapping piece 15L of the left base portion 10L is overlapped on the horizontal bottom portion 11R1 of the right base portion 10R, the overlapping piece 14R of the right base portion 10R is overlapped on the second inclined bottom portion 11L3 of the left base portion 10L, and the overlapping piece 15R of the right base portion 10R is overlapped on the first inclined bottom portion 11L2 of the left base portion 10L. As a result, the engaging claw 14Ra is positioned on the portion of the second inclined bottom portion 11L3 facing the folded-back piece 14L.

[0031] Next, as shown in FIGS. 2 and 4(b), the folded piece 14L (region 54L formed on one side 50Lb of the left portion 50L) is folded back along the folding line 85 so as to sandwich the engaging claw 14Ra between the folded piece 14L and the second inclined bottom portion 11L3, thereby assembling the left base portion 10L and the right base portion 10R (assembly process). At this time, the engaging claw 14Ra is abutted against the inside of the folded fold of the folded piece 14L, engaging the folded piece 14L with the engaging claw 14Ra. In this way, the corner member 1 shown in FIG. 2 is assembled.

[0032] As described above, in the corner member 1 of the building structure 100 of this embodiment, the engaging claw 14Ra abuts against the inside of the fold of the folded piece 14L, engaging the folded piece 14L with the engaging claw 14Ra, making them less likely to come apart. Therefore, even without using fasteners such as rivets, the left portion 50L (i.e., the left base portion 10L) and the right portion 50R (i.e., the right base portion 10R) of the steel plate 90 are less likely to come apart, making it possible to maintain the assembled state of the left portion 50L and the right portion 50R of the steel plate 90. In this way, a corner member 1 can be obtained that can maintain the assembled state of the left and right base portions 10L, 10R without using fasteners such as rivets.

[0033] The folding process of joining one side 50La of the left portion 50L (left base 10L) with one side 50Ra of the right portion 50R (right base 10R), and the assembly process of folding back the folded piece 14L (area 54L formed on one side 50Lb of the left portion 50L) so as to sandwich the engaging claw 14Ra between it and the second inclined bottom 11L3 are usually performed manually, but since the protruding length of the folded piece 14L is longer than the connection length with the side 50Lb (second side), it can be folded back relatively easily with fingers, which speeds up the assembly process.

[0034] Furthermore, the engaging claws 14Ra extend from the periphery of the overlapping filter piece 14R. This allows the engaging claws 14Ra to be formed when forming the overlapping filter piece 14R, rather than forming the engaging claws 14Ra separately from the overlapping filter piece 14R by protruding them from one side 50Ra of the right portion 50R, thereby improving the strength of the engaging claws 14Ra and facilitating their formation.

[0035] While preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments and various modifications are possible within the scope of the claims. For example, in the above-described embodiment, the overlapping filter pieces 14R and 15R are formed on the right base portion 10R, and the overlapping filter piece 15L is formed on the left base portion 10L. However, the overlapping filter pieces may be formed on only one of the base portions. Furthermore, the engaging claw 14Ra does not have to extend from the periphery of the overlapping filter piece 14R. In this case, the engaging claw 14Ra may be provided on one side 50Ra of the right portion 50R, protruding from the boundary between the side 50Ra and the side 50Rb.

[0036] Furthermore, the corner members as steel plate accessories in the above-mentioned embodiments may be installed at the corners of buildings, and can also be used between two adjacent flashing materials, between wall ventilation partition members, between overhanging flashing materials, between roof materials (ridges, etc.), etc. [Explanation of symbols]
