Description

The present invention relates to an outer wall structure in which the lower ground of the outer wall panel is tiled or painted.

According to Patent Document 1, when an earthquake occurs, the joint portion is deformed due to the behavior of the outer wall base material, so that the tile covering the joint portion is chipped or cracked, and troublesome repair work involving replacement of the tile is required. It is pointed out that it will be. Then, in order to solve such a problem, it is disclosed that the joint portion between the outer wall base materials is covered with the tile unit for the joint portion. In addition, screws are inserted into the long holes for inserting screws formed in the fixing plate of the tile unit for joints, which causes the joints to be deformed by the behavior of the outer wall base material in the event of an earthquake, and is used for joints. Even if a load is applied to the tile unit, the load is absorbed by the misalignment of the joint tile unit with respect to the screw within the range of the slot for screw insertion, and the damage to the tile is reduced.

Patent No. 5387203

However, Patent Document 1 does not describe any measures against the case where the out-of-plane rigidity of the outer wall panel is different from each other. Since the conventional outer wall structure is a structure that is covered with a dedicated tile unit for joints, there is a drawback that such a dedicated tile unit for joints is required. Further, when a plaster wall is constructed on the outer wall panel, cracks may occur in the plaster wall at the joint portion between the outer wall panels, but the tile unit for the joint portion as described above is coated as described above. It is not a countermeasure against cracks in the wall.

In view of the above circumstances, the present invention is suitable for a structure used for adjacent outer wall panels having different out-of-plane rigidity, and in the case of a tiled finish, a tile unit dedicated to the joint portion can be eliminated. Further, in the case of finishing the plaster wall, it is an object of the present invention to provide an outer wall structure capable of suppressing the occurrence of cracks in the plaster wall at the joint portion between the outer wall panels.

The outer wall structure of the present invention is an outer wall structure in which the lower ground of the outer wall panel is tiled or painted in order to solve the above-mentioned problems. In the outer wall structure, adjacent vertical frames of adjacent outer wall panels having different out-of-plane rigidity are used. It is characterized in that it is located between them and is provided with a regulating means for regulating the misalignment of the adjacent vertical frames in the out-of-plane direction.

With the above configuration, even if a load in the out-of-plane direction is applied to adjacent outer wall panels having different out-of-plane rigidity, the vertical frames adjacent to each other due to the provision of the above-mentioned restricting means are provided. Since the displacement of the tiles in the out-of-plane direction is regulated, cracking of the tiles at the joints can be suppressed even if a tile unit dedicated to the joints is not used. In this case, it is possible to suppress the occurrence of cracks in the plaster wall at the joint portion.

The regulating means may be provided on the indoor side of the vertical frame. According to this, the above-mentioned regulatory means do not become an obstacle in the tiled finishing and the plastered wall finishing of the outer wall panel.

The regulating means is composed of a plate-shaped member, and the plate-shaped member may be supported by a support portion provided on the vertical frame. According to this, it is possible to regulate the misalignment of the adjacent vertical frames in the out-of-plane direction with a simple structure made of the plate-shaped member.

Alternatively, the regulating means may be composed of a hooking member having a hooking recess and may be hooked on a hook portion provided on the vertical frame. According to this, the restricting means can be attached to the vertical frame by a simple hooking operation.

Alternatively, the regulating means may be an extension portion extending from a vertically long frame reinforcing member fixed to a vertical frame of an outer wall panel having low out-of-plane rigidity among adjacent outer wall panels. According to this, it is possible to regulate the misalignment of adjacent vertical frames in the out-of-plane direction while also reinforcing the vertical frame of the outer wall panel having low out-of-plane rigidity.

The extension portion may be formed of a portion bent by making a notch in a part of the frame reinforcing member. According to this, the extension portion can be formed easily and inexpensively as compared with the case where another member is attached to the frame reinforcing member by welding or the like.

The regulatory means may allow in-plane movement of the outer wall panel. According to this, it is possible to suppress a defect caused by restraining the movement of adjacent outer wall panels in the in-plane direction.

One of the adjacent outer wall panels may be an outer wall panel having an opening, and the other may be an outer wall panel forming a corner portion.

According to the present invention, the misalignment of adjacent vertical frames of adjacent outer wall panels in the out-of-plane direction is regulated, so that the tiled finish can be achieved without using a tile unit dedicated to the joint portion. It is possible to suppress the cracking of the tile at the joint portion, and in the case of finishing the painted wall, it is possible to suppress the cracking of the painted wall at the joint portion.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
The outer wall structure according to this embodiment is a curtain wall type outer wall structure, and as shown in FIGS. 1 and 2, the outer wall panel 1 and the outer wall panel 2 have a structural portion adjacent to each other. For example, the outer wall panel 1 is a corner panel constituting a protruding corner of a building, and the outer wall panel 2 is an opening panel having an opening (window) 2a. The out-of-plane rigidity of the outer wall panel 2 which is the opening panel is smaller than the out-of-plane rigidity of the outer wall panel 1 which is the corner panel.

The outer wall panel 1, which is the corner panel, includes a vertical frame 11 having a substantially U-shaped cross section, a corner plate 12 having a substantially L-shaped cross section, and the like. Further, the outer wall panel 2 which is the opening panel includes a vertical frame 21 having a substantially U-shaped cross section, a horizontal frame 22 having a substantially U-shaped vertical cross section, and the like. No pillar is provided at a position closest to the indoor side of the outer wall panel 1, and a space portion on which a plate-shaped member can be arranged is formed on the indoor side of the vertical frame 11 of the outer wall panel 1. Has been done.

A base plate 13 is provided on the outdoor side of the outer wall panel 1, and tiles (not shown) are attached to the outdoor side surface of the base plate 13 by adhesion, hooking, or the like. In FIG. 2, a portion of the opening (window portion) 2a of the outer wall panel 2 is crossed, and a sash frame 2b provided at this portion appears. Similar to the outer wall panel 1, a base plate 23 is provided on the outdoor side of a portion other than the opening 2a, for example, an upper portion of the outer wall panel 2, and tiles are provided on the outdoor side surface of the base plate 23. Is attached by gluing or hooking. Then, tiles can be provided at the joint portion between the base plate 13 and the base plate 23 so as to straddle the joint portion. Therefore, for example, it can be a horse joint instead of a potato joint. If the opening 2a is small and a non-opening is formed between the left and right sides of the opening 2a and the vertical frame 21 of the outer wall panel 2, tiles are also attached to the non-opening. In addition, tiles may be provided across the joints.

As shown in FIGS. 3A and 3B, for example, the plate thickness is 3.2 mm so as to straddle the vertical frame 11 of the outer wall panel 1 and the vertical frame 21 of the outer wall panel 2 that are close to each other. The plate-shaped member 3 is arranged on the indoor side surface of the vertical frames 11 and 21. The plate-shaped member 3 serves as a regulating means for regulating the misalignment of the adjacent vertical frames 11 and 21 in the out-of-plane direction, and is a bolt screwed into the vertical frames 11 and 21. It is supported and fixed by the support portion) 41. The bolt 41 is screwed into a nut 42 fixed to the inside of the vertical frames 11 and 21 by welding or the like.

Further, the through hole 3a through which the bolt 41 is inserted in the plate-shaped member 3 is a loose hole, and is, for example, a long hole long in the lateral direction as shown in FIG. A washer is provided between the head of the bolt 41 and the through hole 3a of the plate-shaped member 3.

With the above configuration, even if a load in the out-of-plane direction is applied to the outer wall panel 2 having the opening 2a, the out-of-plane rigidity differs from each other due to the provision of the plate-shaped member (regulatory means) 3. The misalignment of the adjacent vertical frames 11 and 21 of the adjacent outer wall panels 1 and 2 in the out-of-plane direction is regulated, and the tiled finish is achieved without using a tile unit dedicated to the joint portion. Cracking of tiles at the joints of the case can be suppressed. Further, in the case of finishing the plaster wall, it is possible to suppress the occurrence of cracks in the plaster wall at the joint portion.

When the plate-shaped member 3 is provided on the indoor side of the vertical frames 11 and 21, there is an advantage that the plate-shaped member 3 does not become an obstacle in the tiled finish and the plastered wall finish of the outer wall panels 1 and 2.

Further, if the plate-shaped member 3 is used as the regulating means as described above and the plate-shaped member 3 is supported and fixed by the bolts (supporting portions) 41 provided on the vertical frames 11 and 21, the plate-shaped member 3 is supported and fixed. With a simple configuration using the shaped member 3, it is possible to regulate the displacement of the adjacent vertical frames 11 and 21 from each other in the out-of-plane direction.

When the through hole 3a of the plate-shaped member 3 is a loose hole, the adjacent outer wall panels 1 and 2 are allowed to move in the in-plane direction. According to this, it is possible to suppress a defect caused by restraining the movement of the adjacent outer wall panels 1 and 2 in the in-plane direction. Although a horizontally long long hole is shown as a loose hole, it may be vertically long. Further, instead of the hole, an inverted U-shaped cut portion that opens on the lower side and serves as an entrance may be used.

Next, other embodiments will be described. As shown in FIGS. 5, 6 (A) and 6 (B), in this embodiment, the regulating means comprises the hook member 5.

It has a substantially U-shaped cross section. The first surface portion 51 is formed with two inverted U-shaped hook recesses 51a having an opening on the lower side and serving as an entrance side by side. Further, a contact portion 51b that contacts the outer wall panels 1 and 2 is formed on the upper side of the first surface portion 51, and a flat plate is separated from the outer wall panels 1 and 2 on the lower side of the contact portion 51b. The portion is located, and the hook recess 51a is formed in the flat plate portion.

The neck portion of the hook bolt (hook portion) 43 can be engaged with the hook recess 51a. The hook bolt 43 is screwed into a nut 42 fixed to the inner side surfaces of the vertical frames 11 and 21 by welding or the like. Further, the distance between the first surface portion 51 and the second surface portion 52 is set to be about the same as the thickness of the head of the hook bolt 43. When the hook member 5 is attached to the hook bolt 43, the head of the hook bolt 43 and the flat plate portion of the first surface portion 51 come into contact with each other, and the contact with the contact portion 51b causes the hook to be hooked. The member 5 is attached to the hook bolt 43 without rattling.

Further, at the lower end of the second surface portion 52, a guide portion 52a that inclines downward so as to move away from the vertical frames 11 and 21 is formed, and the guide portion 52a causes the first surface portion 51 and the second surface portion 52 to be formed. It is easy to insert the head of the hook bolt 43 into the space. Further, a guide portion that spreads downward is formed at the entrance portion of the hook recess 51a, so that the neck portion of the hook bolt 43 can be easily inserted.
