Description

[Detailed Description of the Invention] [Purpose of the Invention] Industrial Application Field The present invention relates to the surface finishing of structures such as buildings, and relates to a surface finishing structure whose surface is tiled.

In this specification, the term tile refers not only to the thin plate-shaped fired clay products that are usually applied to the surface of walls, etc., but also to all thin plate-shaped products made of other materials that are similarly applied to the surfaces of walls, floors, etc. . Therefore, it naturally includes not only ceramic tiles and glass tiles but also thin bricks.

Further, in this specification, the term "up and down" referring to a direction means a direction as a surface of a finished wall or the like. Further, the surface indicating the direction is the surface in the finished state, and the back surface means the opposite side.

BACKGROUND OF THE INVENTION It is well known that tiles are used to finish the surfaces of structures such as exterior walls, interior walls, and gates. Furthermore, thin plate tiles have been widely used in recent years because they can be used on the exterior walls of buildings to give the building a heavy appearance similar to masonry. The conventional finishing method using tiles requires the use of adhesives such as mortar, and therefore requires skill.

The present applicant has already provided a surface finishing structure that can easily obtain the surface of a tiled structure without such drawbacks of conventional construction (Utility Application No. 59-28311, Utility Application No. 59-124579). etc.). In all of these, tiles are engaged and fixed to a support made of a metal profile such as aluminum. The support body is provided with an engagement strip, the tile is formed with an engaged part that is engaged with the engagement strip, and the tile is fixed to the support body by engaging the engaged part with the engagement strip. It is.

Problems that the invention aims to solve By the way, the surfaces of structures are not only flat. Many have protruding corners and inward corners. The tiles must be supported by supports at these locations as well, but for this purpose, supports must be prepared for the outside corners and for the inside corners. However, although many of the exit angles and entrance angles are right angles, not all of them are necessarily right angles. Therefore,
Aside from the right angle ones, it would be quite uneconomical to prepare all the other angles as well. Therefore, it is conceivable to bend the support to match the protruding and entering angles on site, but it is difficult to bend the support because it has a protruding strip on its surface. To solve this problem, he devised the idea of making cuts at right angles to these strips (Utility Application No. 158306, 1983). However, even if the notch itself is straight, if the notch is wide, it may bend diagonally when folded.
Those that are bent diagonally are useless as they will not allow you to install tiles that must be installed horizontally. Further, there was a problem in that a material with a simple cut could be used for the application section, but it could not be used for the inside corner.

The present invention aims to improve these points.

[Structure of the device] Means for solving the problem The present invention is characterized in that a V-shaped notch is made in a direction perpendicular to the longitudinal direction of the engaging strip or other strip that protrudes from the surface, and the cut is made at the part where the cut is made. The support is bent at an angle corresponding to the angle of the corner and the inside corner, the bent support is attached to the outside corner and the inside corner, and a tile having an engaged portion on the back side is engaged with the support. It is characterized by: It is desirable that the opening angle of the V-shape is 90 degrees.

Function When a V-shaped notch is made at right angles to the engagement strip or other strips protruding from the surface of the support, the tip of the notch becomes thinner and has no width, so it can be bent horizontally without being diagonal. . Also, since the cut is V-shaped, it can be folded inward. Therefore, the support can be bent at any angle at that point, and there is no need to make special supports for the protruding or inward corners using a general support, and it can be bent on site to fit the width of the structure. It can be made compatible. Furthermore, the same tiles can be installed in the same way by simply changing the angles of the projecting corners.

Embodiment FIG. 1 is a front view of a wall surface according to an embodiment of the present invention, in which horizontal joints 1 are formed above and below tiles 2 to create a masonry-like wall. The right edge of the diagram is the end of the wall bent at 90 degrees. Although the example shown in the figure has only horizontal joints and no vertical joints, it is free to provide a space between the tiles 2 and provide vertical joints. Also,
Although this embodiment uses a wall, it can be similarly used for interior decoration, the surface of a gate, etc. In this embodiment, a tile is engaged and fixed to a later-described support attached to a wall structure, so the support, tile, etc. will be explained below.

The support body 3 is a long object formed from an extruded aluminum alloy member, and is a long object to which a plurality of tiles can be attached to one support body 3 side by side. As shown in FIG. 2, the side surface shape is as shown in FIG. Furthermore, the first engagement article 5
A spacing maintenance strip 7 is provided above. This spacing maintenance strip 7 is for separating the bottom surface of the tile 2 for a certain period of time so that it does not come into contact with the surface of the base 4 when the tile 2 is engaged and attached. Further, at the upper end of the base 4, there is provided a tip 8 that rises in the direction of the surface of the base by approximately the thickness of the base and extends upward from the tip in parallel with the base. A return line 9 is formed. This embodiment uses the first and second engaging strips 5, 6 and the spacing maintenance strip 7.
Three sets are formed on one support member 3 at predetermined intervals. Of course, it is not limited to three groups.

The first engagement strip 5 has a shape in which a tip 5b of a protruding strip 5a that protrudes slightly downward from the surface at approximately the center of the base 4 is bent obliquely upward. The reason why the protruding strip 5a is made to protrude slightly diagonally downward is to guide the water that has entered here to the base of the receiving tip 5b. The tile 2 is engaged with this upwardly directed tip 5b as described later. On the other hand, the first
The second engagement strip 6, which is provided on the lower side at a predetermined distance from the engagement strip 5, has an inclined section 6a that is inclined diagonally downward from the base 4, and a mounting section that extends downward parallel to the base 4 from its tip. 6b, an upright portion 6c that stands upright slightly diagonally downward from the tip of the mounting portion 6b, and a holding portion 6d provided at the tip of the upright portion 6c. The holding portion 6d is parallel to the base portion 4 together with the placing portion 6b. The distal end portion 8 having the water return strip 9 attached to the lower stage of the support is inserted between the mounting portion 6b of the second engagement strip at the lowest stage of the three sets of strips and the base portion 4. The surfaces of these placement portions 6b are formed to be flush with the surface of the spacing maintenance strips 7. That is, the inclined portion 6a and the mounting portion 6b constitute another interval maintaining strip.

The reason why the tiles 2 are separated from the surface of the support 3 by the spacing maintenance strip 7 as described above is that the water that has entered the back side of the tile 2 attached to the support 3 is allowed to flow over the surface of the support 3. This is to prevent it from getting inside. In order to allow water to flow over the surface of the support as described above, cutouts are provided at appropriate locations on each of the stripes.

The pin receiver 10 formed on the first engagement strip 5 in the middle in the figure is for inserting a pin (not shown) in order to make it easier to draw a straight line when connecting the supports 3 horizontally.

In the case 3B used for the protruding or inward corners of the support having the above structure, V-shaped cuts 11 are made linearly in each strip as shown in FIG. This incision is made by cutting a cutter such as a milling cutter whose cutting edge is formed at a 90 degree angle into the strip protruding from the surface of the base 4 up to its base, as shown by the dashed line in FIG.

As shown in FIG. 4, the tile 2 has at least a rectangular surface and a predetermined thickness. A protruding portion 12 that protrudes upward is formed on the back side of the upper surface, while a hanging portion 14 that protrudes downward is formed on the front side of the lower surface 13. As shown in FIG. 5, when the tile is engaged with and attached to the support 3, the protrusion 12 and the hanging part 14 are located in the space between the hanging part 14 and the support 3. 12 is positioned, and the hanging portion 14 covers the upper end. This polymerized structure forms the horizontal joint 1.

A first engagement strip 5 is located approximately in the center of the back surface of this tile 2.
A notched inclined groove 16 serving as a first engaged portion is provided, and an upwardly facing holding portion 6d of the second engaging strip 6 is inserted into the lower surface 13 and engaged. A groove 17 is formed to serve as a second engaged portion. The shape of the above-mentioned inclined groove 16 is determined by attaching the tile 2 to the support 3 from the surface side by applying it to the support 3 from above like the tile 2A in FIG. Any shape may be used as long as it can accommodate the above-mentioned elements and allow the tip end 5b of the first engagement strip 5 to come into contact with it.

The tile 2 is engaged with the support body 3 as described above, but in order to make this engagement stronger, as shown in the figure, the raised portion 6c of the second engagement strip 6 and the tile 2
An elastic retainer 18 is inserted between the tip of the protrusion 12 and the tip of the protrusion 12. As shown in FIG. 7, this retainer 18 is made of thin plate-like spring steel and has a shape parallel to both ends of an arc, but this shape is not particularly limited. Without,
Any type of material that presses the tile 2 downward may be used.

The tiles used for the projecting corners are as shown in FIG. 6, and the tiles shown in FIG. 4 mentioned above are cut at 45 degrees and joined together with adhesive or the like. In this example, an epoxy resin adhesive was used. Of course, it is also possible to form the shape from the beginning into the shape shown in the figure and then bake it. If the angle of the projecting corner is not a right angle, it is a matter of course that it should be at a corresponding angle. Needless to say, for the inside corner tiles, it is best to glue one side in the opposite direction. Ordinary tiles can also be used in the inner corners.

In order to construct a wall surface according to this embodiment, as shown in FIG. and lower the tile 2 from above to engage the support as shown in the figure.
It may be fixed with the retainer 18.

As shown in FIG. 7, a support member 3B having a V-shaped notch is bent and attached to the protruding corner according to the angle of the protruding corner, and the tile 2 is attached in the same manner as described above. The tile 2 is fixed to the support 3 after the support 3 is attached to the entire surface including the projecting corners.

A plurality of supports 3 are arranged in parallel so that the tip of the lower one rests on the base end of the upper one, partially overlapping, and is covered by the placing part 6b. It becomes like this.
Therefore, watertightness is extremely good. In addition, at the protruding corners, the same support is folded with the base 4 intact and only the protruding strips cut off, leaving the base intact, so there is no risk of creating gaps and watertightness is maintained. can do. For example, in the case where simple flat supports are brought together at their protruding corners, a gap is created at the joint, resulting in a decrease in watertightness.

Since the support 3B in FIG. 3 has a V-shaped cut, it can be bent inward. Therefore, by attaching it to the inner corner, it is possible to attach the tile to the inner corner using a support in the same manner as described above.

Although the above embodiment uses special tiles for the outside and inside corners, regular tiles may be used instead as shown in FIG.

[Effects of the Invention] As described above, according to the present invention, anyone can obtain a tile-finished surface extremely easily because the tile is simply engaged with and fixed to the flat strip support.

In addition, it is possible to correspond to the protruding corner portion and the inner corner portion without using a special support by simply making cuts and folding the stripes protruding from the surface of the same support. Handling is easy even at the inside corners.

Furthermore, in the present invention, since the notch is V-shaped, it does not bend when folded, and can be used for both an outside corner and an inside corner as described above.
