Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to an exterior wall structure suitable for an outer wall of a building, for example, between openings of upper and lower floors of a high-rise building.

<Prior Art> The exterior wall of a building, in particular, a portion other than an opening such as a sash is provided with various designs as an exterior in view of the aesthetics of the building.

One of the exteriors is tiled.

FIG. 5 is a cross-sectional side view of essential parts showing a conventional tiled outer wall.

In the figure, reference numeral 1 is an appropriately large outer wall, which is supported by a predetermined frame or the like. Sash frames 2 and 3 for upper and lower floor openings are provided on the upper and lower ends of the outer wall body 1 via mounting frames 1a and 1b.

In the figure, the sash frame 2 on the upper floor shows the lower part of the frame, and the sash frame 3 on the lower floor shows the upper part of the frame.

Further, predetermined glass plates 4 and 5 are fitted into the outdoor side frame portions 2a and 3a of the sash frames 2 and 3, respectively. 6a, 6b, 6c are tiles, which are attached to the surface of the outer wall body 1 on the outdoor side through a mortar 7 in a required number.

Between the tiles 6a, 6b, 6c, joints are provided at appropriate intervals so as to be in close contact with the mortar 7. Further, between the outdoor side frame portions 2a, 3a of the sash frames 2, 3 and the adjacent tiles 6a, 6c are filled with a backup material 8, 8 and a sealing material 9, 9 in order to prevent rain. .

Thus, the color, size, shape, etc. of the tile 6a are variously set so that the outer wall portion other than the opening portion can be designed.

<Problems to be Solved by the Invention> However, the above-mentioned mortar 7 may cause a contraction action over time, and may cause a crack 10. When this crack 10 reaches the adhesion surface between the tile 6a and the mortar 7,
Due to the permeation of rainwater, the tile 6a or the like may be peeled off from its adhesive surface in extreme cases. Further, when the crack 10 extends from the outdoor side surface to the indoor side surface, there is a problem that rainwater leaks indoors. Furthermore, since the mortar is applied to the outdoor side surface of the outer wall body 1 and the surface such as the periphery of the sash frames 2 and 3, the tiles 6a and the like are attached after that, which is complicated in construction and requires skill together with mortar application. It was a thing. In short, there is still room for improvement as a means for exterior wall exteriors.

The present invention is provided in order to solve the above-mentioned conventional problems, and not only the durability is significantly improved without causing defects such as cracks, but also the workability of the outer wall exterior is improved. The purpose is to improve.

<Means for Solving the Problems> In order to achieve the above-mentioned object, the present invention has an outer wall exterior structure in which the exterior side of the outer wall body is covered with an exterior panel, and the exterior panel is attached to a metal plate and this metal plate. A plurality of tiles that have been subjected to joint processing and provided with a plurality of locking tools on the outer surface side of the metal plate, and the tiles having the locked portion are integrally attached to the metal plate by the locking of the locking tools. It is configured by.

<Operation> Since the outdoor side of the outer wall is covered with the metal plate, rainwater does not leak from the metal plate surface to the indoor side. Further, since the tile is locked to the metal plate surface by the locking tool, even if rainwater penetrates between the tile and the metal plate surface, the tile is prevented from falling off the metal plate surface.

<Embodiment> A preferred embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a sectional side view of a main part of an outer wall according to the present invention, and FIGS. 2 (A) and 2 (B) are front and side views showing the shape of a first embodiment of a tile, and FIG. 3 is a tile. FIG. 4 is a side view showing the shape of the second embodiment of FIG. 4 and FIG. It should be noted that the same members and the same means as those of the related art are designated by the same reference numerals.

In the figure, sash frames 2 and 3 for openings are provided at the upper and lower ends of the outer wall body 1. Reference numeral 11 denotes a metal plate, which is provided with stepped mounting flanges 11a and 11b on the upper and lower sides and is arranged on the outdoor side of the outer wall body 1 by means described later. This metal plate
The vertical dimension of 11 except for the mounting flanges 11a and 11b is substantially the same as the vertical dimension of the outer wall body 1.

Then, the metal plate 11 is attached to the standing pieces 2b and 3b formed on the lower surface and the upper surface of the sash frames 2 and 3, respectively, to attach the mounting flanges 11a and 11b.
Are fixed by joining them with screws. As a result, the outdoor side of the outer wall body 1 is covered. 12 is a tile, which is integrally attached to the metal plate 11. The metal plate 11 and the tile 12 form an exterior panel of the outer wall body 1.

The tile 12 is attached to the metal plate 11 by the structure shown in FIGS. 2 to 4, for example. The tile shown in Figure 2
The front contour 12 has a known shape, and projections 12a and 12b are formed on the upper side and the lower side thereof on one side in the plate thickness direction. The protrusions 12a and 12b have a function as a locked portion to which a locking tool of the metal plate 11 described later is locked.
In contrast to the projections 12a and 12b described above, FIG. 3 shows the tile 13 in which grooves 13a and 13b are formed to serve as locked portions. Further, although not shown, as the locked portion, in addition to the above, holes can be opened at an appropriate interval on the upper and lower sides of the tile.

The metal plate 11 for locking the tiles 12, 13 and the like has the structure shown in FIG. Reference numerals 14a and 14b are a pair of locking tools, which are formed in a substantially L-shaped cross section to lock the locked portions formed by the projections 12a and 12b and the grooves 13a and 13b of the tiles 12 and 13 and the like. .
The locking tools 14a, 14b support the tiles 12, 13 by hooking the upper and lower sides thereof. Therefore, the tiles 12 and 13 are arranged in pairs corresponding to the distance between the locked portions, and a plurality of pairs are fixed to the outer surface side of the metal plate 11 by welding or the like. In FIG. 4, the intermediate portion is omitted and only the locking tools 14a and 14b located on the upper end side and the lower end side of the metal plate 11 are shown. This locking tool 14a, 1
The length of 4b may be equal to the width of the tiles 12 and 13, or may be short so as to partially lock several places. Also,
If the locked portion of the tile has the above-described opening hole shape, the locking members 14a and 14b use bar members instead of the plate members in the illustrated example. Reference numeral 15 is a screw hole used when the sash frames 2 and 3 are joined by screwing.

The exterior panel composed of the metal plate 11 and the tile 12 is specifically completed by the structure shown in FIG.

That is, the joint treatment material 16 is filled as a tile joint between the tiles 12 that are locked and supported by the locking tools 14a and 14b. Then, backup materials 16a, 16 are provided at the joints between the mounting flanges 11a, 11b of the metal plate 11 and the vertical pieces 2b, 3b of the sash frames 2, 3.
It is filled with b and sealing materials 17a and 17b. This filling is to match the dimensions of the stepped portions of the mounting flanges 11a and 11b, and between the sash frames 2 and 3 and the tile 12, a backup material 8 and a sealing material 9 and 9 are provided as separate members. It is filled in the same way as before. Therefore, the former backup material 16
If the two members of a, 16b and sealing materials 17a, 17b are used as the primary filling material, the latter backup material 8, 8 and sealing materials 9, 9 can be said to be the secondary filling material, and the sealing effect is due to the two layers. It is preferable. However, the thickness of the primary filler may be increased to form a single layer without the secondary filler.

According to the above configuration, since the metal plate 11 is a single plate, rainwater does not leak from the surface of the metal plate to the indoor side. Similarly, since the sealing members 17a and 17b are used to seal the joints with the sash frames 2 and 3 as well, it is possible to prevent rainwater from penetrating from the joints to the indoor side.

Further, since the tile 12 is locked to the metal plate 11 by the locking tools 14a and 14b, even if the sealing effect of the joint filler 16 or the like is cut off, the tile 12 does not drop off.

Further, since the tile 12 is locked to the metal plate 11, it is possible to assemble them in the factory in advance. This enables uniform factory production as an exterior panel. Therefore, in the building construction site, the exterior panel can be completed by arranging the exterior panel prepared in advance on the outdoor side of the outer wall body and only sealing the joint portion. Therefore, it is possible to save labor in the construction work and shorten the construction.

Although the sash frame is used as the joining member when the metal plate 11 is arranged on the outdoor side of the outer wall body 1 in the above-described embodiment, the present invention is not limited to this. For example, in the case of an outer wall having no opening such as a sash, it is possible to provide brackets on the frame or the frame that supports the outer wall body 1 at predetermined intervals and to join them.

<Effects of the Invention> As described above, according to the present invention, since the panel in which the tile is locked to the metal plate is used as the exterior of the outer wall body, the tile is removed from the metal plate over the years. It does not cause the changes that occur. Therefore, the exterior structure having excellent durability can be obtained.

Further, since the tiles can be locked to the metal plate and completed as an exterior panel in advance, it is possible to provide an exterior wall exterior structure having excellent practicality, such as being able to perform on-site construction as an extremely simple work. it can.
