The projecting corner structure includes an outer wall surface material 10, a projecting corner member 100, a caulking material 20, a tape member 30, a spacer 40, a rim 50, a heat insulating board 60, a pillar 70, and the like.

The outer wall surface material 10 forms the surface (outer surface) of the outer wall. A pair of outer wall surface materials 10 are provided so as to be orthogonal to each other. The ends of the pair of outer wall surface materials 10 are arranged with a gap between them. The projecting corner member 100 is installed vertically between the ends (projecting corners) of a pair of outer wall surface materials 10. The protruding corner member 100 is provided so as to extend from between the ends of the pair of exterior wall panels 10 to the respective back sides of the pair of exterior wall panels 10. Note that a detailed description of the configuration of the protruding corner member 100 will be given later.

The caulking material 20 is provided between the ends of the pair of outer wall surface materials 10 and the protruding corner member 100. The caulking material 20 forms a joint between the ends of the pair of outer wall surface materials 10 and the protruding corner member 100. The tape member 30 prevents the caulking material 20 from adhering on three sides. The tape member 30 is provided between the caulking material 20 and the protruding corner member 100.

The spacer 40 maintains a gap between the back side of the pair of outer wall surface materials 10 and the protruding corner member 100. The spacer 40 is provided between the back side of the pair of outer wall surface materials 10 and the protruding corner member 100. The furring 50 forms a wall base material. A pair of furring edges 50 are provided so as to be perpendicular to each other. The pair of furring edges 50 are brought into contact with the projecting corner members 100, respectively.

A pair of heat insulation boards 60 are provided so as to be orthogonal to each other. The pair of heat insulation boards 60 are brought into contact with the back sides of the pair of furring edges 50, respectively. The pillars 70 form the structural frame of the building. The pillars 70 are provided so as to abut on the pair of furrings 50 via the pair of heat insulating boards 60 .

Below, the configuration of the protruding corner member 100 will be described in detail using FIGS. 3 and 4.

The protruding corner member 100 is formed by appropriately bending one metal plate member. The protruding corner member 100 includes a first portion 110, a second portion 120, and a third portion 130.

The first portion 110 is disposed between the end portions of a pair of outer wall members 10 that are orthogonal to each other on the projecting corner member 100 side. The first portion 110 is formed in a substantially L-shape with two sides orthogonal to each other when viewed from above. In addition, below, the part extended forward among the said two sides is called the front extension part 111. Further, the portion extending to the right is referred to as a rightward extending portion 112. Here, the front extension part 111 and the right extension part 112 are the same except for the direction in which they are arranged (the direction in which they are extended). Therefore, unless otherwise specified, the configuration of the front extension part 111 will be described below, and the description of the configuration of the right extension part 112 will be omitted.

The front extending portion 111 is formed by bending a single plate-like member so that it becomes double. Specifically, the front end portion of the front extending portion 111 corresponds to a folded portion of the plate-like member. That is, the front extending portion 111 is formed such that two plate-like members extend rearward from a folded portion of the front end. Hereinafter, of the two plate-like members, the one disposed on the left side will be referred to as a first left-hand member 115. Moreover, the one disposed on the right side is referred to as a first right side member 116.

The first left side member 115 and the first right side member 116 are formed to have the same size and shape. Further, the first left side member 115 and the first right side member 116 are formed to face each other and be parallel to each other. Moreover, a slight gap is formed between the first left side member 115 and the first right side member 116, as shown in FIG. That is, the first left side member 115 and the first right side member 116 are not in close contact with each other.

Note that, as described above, in this embodiment, the first left side member 115 and the first right side member 116 are not in close contact with each other, but the present invention is not limited to this. That is, the first left side member 115 and the first right side member 116 may be in close contact with each other. Further, the first left side member 115 and the first right side member 116 do not need to be in close contact with each other, but may be in partial contact with each other.

The second portion 120 is located at the rear left of the first portion 110. The second portion 120 is formed by a second left front portion 121 that is located at the front left portion and has a substantially L-shape when viewed from above, and a second right rear portion 122 that is located at the right rear portion and is approximately L-shaped when viewed from above. be done. Here, the second left front part 121 and the second right rear part 122 are the same except for the orientation in which they are arranged. Therefore, unless otherwise specified, the configuration of the second left front portion 121 will be described below, and the description of the configuration of the second right rear portion 122 will be omitted.

The second left front portion 121 includes a second front member 125 and a second left side member 126. The second front member 125 is a plate-shaped member with a plate surface facing in the front-rear direction. The right end of the second front member 125 is connected to the rear end of the first left member 115 of the front extension 111 . The second front member 125 is formed to be perpendicular to the first left member 115. The second left side member 126 is a plate-shaped member with a plate surface oriented in the left-right direction. The front end of the second left side member 126 is connected to the left end of the second front side member 125. The second left side member 126 and the second front side member 125 are formed to be orthogonal to each other. The length of the second left side member 126 in the lateral direction is shorter than the length of the second front side member 125 in the lateral direction.

In this way, the second portion 120 is formed by the second left front portion 121 and the second right rear portion 122 to have a substantially rectangular shape in plan view. That is, in the second portion 120, the second left front portion 121 and the second right rear portion 122 form a space that is substantially rectangular in plan view and extends in the vertical direction. Further, in a plan view, the left rear portion of the second portion 120 is formed with a larger opening (see symbol H2 in FIG. 3) than the opening (see symbol H1 in FIG. 3) in the right front portion of the second portion 120.

The third portion 130 is located approximately to the rear left of the second portion 120. The third portion 130 is formed by a third left side member 131 extending leftward and a third rear side member 132 extending rearward. Here, the third left side member 131 and the third rear side member 132 are the same except for the direction in which they are arranged. Therefore, unless otherwise specified, the configuration of the third left side member 131 will be described below, and the description of the configuration of the third rear side member 132 will be omitted.

The third left side member 131 is a plate-shaped member with a plate surface facing in the front-rear direction. The right end of the third left member 131 is connected to the rear end of the second left member 126 of the second portion 120 . The third left side member 131 and the third rear side member 132 are formed to be perpendicular to each other.

The protruding corner member 100 is directly or indirectly connected to the structural frame (in this embodiment, the column 70) using the third left side member 131 and the third rear side member 132.

As described above, the protruding corner member 100 is formed by appropriately bending one metal plate member. Further, in the first portion 110, the front extending portion 111 and the right extending portion 112 are formed so that one plate-like member is bent to become double. This improves the rigidity of the protruding corner member 100, and can prevent it from easily deforming, for example, even when a force is applied in a twisting direction (clockwise in plan view). In this way, deformation of the protruding corner member 100 can be suppressed, so that work efficiency at the work site can be improved.

Below, the relationship between the projecting corner member 100 and other members in the projecting corner structure will be explained in more detail using FIG. 5.

As shown in FIG. 5, the end of the outer wall surface material 10 on the protruding corner member 100 side (hereinafter referred to as the "end part 10a") and the first part 110 of the protruding corner member 100 (the front extending part 111 ), and a gap is provided between them, and the caulking material 20 is filled in the gap. Here, although the end portion 10a of the outer wall surface material 10 does not come into contact with the first portion 110 of the projecting corner member 100, the second portion 120 of the projecting corner member 100 (specifically, the end portion 10a of the second left front portion 121 The two left side members 126) are in contact with each other. As a result, the outer wall surface material 10 cannot be moved further toward the protruding corner member 100 than the position shown in FIG. That is, since the width direction of the caulking joint is regulated, it is possible to secure the caulking allowance between the outer wall surface material 10 and the first portion 110, and to prevent the caulking allowance from disappearing. In FIG. 5, for convenience (specifically, to illustrate the tape member 30), it is shown that there is a gap between the end 10a of the outer wall surface material 10 and the second left side member 126 of the projecting corner member 100. However, in reality, there is no gap and they are in contact with each other (via the tape member 30).

Further, as shown in FIG. 5, the bottom of the gap between the end 10a of the outer wall surface material 10 and the first portion 110 of the projecting corner member 100 is formed by the second front side member 125 of the second portion 120. That is, the second front member 125 of the second portion 120 restricts the depth direction of the caulking joint.

Further, as described above, the first portion 110 of the protruding corner member 100 is formed into a substantially L-shape with two sides orthogonal to each other when viewed from above. In this way, on the opposite side of the caulking material 20 across the forward extending portion 111 of the first portion 110, a relatively large space in which no member exists is provided. Therefore, when the projecting corner structure is viewed from a certain angle, although the caulking material is visible, the projecting corner member 100 itself is hardly visible (see FIG. 6(a)). On the other hand, for example, when the protruding corner member is formed in a square shape instead of the L-shape of this embodiment, when the protruding corner structure is viewed from a certain angle, not only the caulking material but also the protruding corner member 100 itself is also visible. In this way, the projecting corner structure (projecting corner member 100) according to the present embodiment can give a smart and stylish impression to those who view the projecting corner structure.

Further, as shown in FIG. 5, the outer end portion 111a of the front extending portion 111 of the projecting corner member 100 is located on the outer side of the surface (outer surface) of the outer wall surface material 10. In this way, it is possible to prevent the caulking material 20 from overflowing. It can also give a smart and fashionable impression (it has excellent design).

In addition, in this embodiment, although the outer end 111a of the front extension part 111 is located outside the surface of the outer wall surface material 10, it is not limited to this. That is, the outer end portion 111a of the front extending portion 111 may be located at the same position as the surface (outer surface) of the outer wall surface material 10 in the front-rear direction (that is, the indoor-outdoor direction).

Note that when the projecting corner structure is vertically long, a plurality of projecting corner members 100 may be arranged vertically in series. In this case, if the positions of the upper and lower projecting corner members 100 are shifted from each other, it is not desirable because the appearance may deteriorate or rainwater may enter from the shifted locations.

Therefore, in the protruding corner member 100 according to the present embodiment, when a plurality of protruding corner members 100 are arranged vertically in a row, a joint J can be used as shown in FIG. 7 . The joint J is a substantially quadrangular prism-shaped member whose longitudinal direction is directed upward and downward. The joint J has approximately the same size as the inside of the second portion 120 of the protruding corner member 100.

In this way, as shown in FIG. 7(a), for example, when two projecting corner members 100 are arranged vertically in a row, the second portion 120 of one of them (lower in FIG. 7(a)) has a joint. Place J. Specifically, the lower half of the joint J is inserted into the second part 120, and the upper half is made to protrude upward from the second part 120. Then, as shown in FIG. 7B, the upper protruding corner member 100 is moved downward, and the upper half of the joint J is inserted into the second portion 120 of the upper protruding corner member 100. In this way, the two upper and lower projecting corner members 100 can be arranged so as to be vertically connected without shifting from each other.

Note that the part into which the joint J is inserted is not limited to the second part 120 of the projecting corner member 100. For example, the forward extending portion 111 of the first portion 110 (between two double plate members) may be utilized.
