Description

The present invention relates to a dry tile construction method for fixing tiles as an outer wall material to a building frame using metal fittings, a bracket rail for attaching tiles as metal fittings used therein, and a dry tile wall structure.

In recent years, as a method of constructing tiles for outer walls, a base material such as a ceramic siding board or a metal plate tile mounting plate having claws is fixed to the wall surface of a building, and the tile is locked or bonded to the base material. A dry method is known in which the tiles are fixed and attached with an agent.

However, ceramic siding boards have a useful life of about 20 to 30 years, which is relatively short compared to the useful life of tiles, and because they expand and contract significantly with temperature changes, the tiles are damaged or peeled off. There are drawbacks that occur. In addition, the method of fixing tiles with an adhesive cannot inspect the inside, cannot cope with the extension of the life of the house, and has problems such as falling off due to deterioration of the adhesive.

In order to solve this problem in the dry method, a method that uses an aluminum base material instead of the siding board (Patent Document 1), and a metal elastic clip or metal mounting instead of the adhesive. A method of fixing tiles using bracket rails (Patent Document 2) has been proposed.

Japanese Patent No. 326623969 Japanese Patent No. 4566280

However, an aluminum base material that can replace a siding board is expensive and causes an increase in construction cost, and also has a large expansion and contraction due to temperature changes, so that there is a problem of tile breakage and peeling like a siding board. Therefore, it is not possible to improve the durability.

In addition, when using a metal mounting bracket rail instead of an adhesive and an elastic clip, a metal mounting bracket rail is mounted on the unevenness of the siding board, which is the base material, and then the mounting bracket rail and tile are used. There is a problem that the work efficiency becomes poor because the troublesome tile mounting work of loading the tile while deforming the bow-shaped elastic clip between the upper end and the tile is required. In addition, since the elastic clip is compressed and locked to the dovetail-shaped slope of the mounting bracket rail fitted to the base material, the elastic clip is compressed and inserted by hand, which puts a heavy burden and pain on the operator's fingers. Will bring.

Moreover, the elastic clip inserted in the gap between the tile and the rail may come off in the event of an earthquake, and there is a drawback that it is difficult to insert the elastic clip into the gap between the tile and the rail. Since it is only pressed vertically by the elastic clip, the force of the elastic clip acts in the direction of dropping off when receiving a force in the direction away from the outer wall surface of the building frame in the event of an earthquake, so the back side of the middle part of the tile It is necessary to form a dovetail groove (a wedge-shaped convex part that serves as a hook) that engages with the dovetail-shaped slope of the mounting bracket rail, and the shape of the tile to be used is restricted.

The present invention provides a tile mounting bracket rail for dry tile construction in which the tile is stably fixed for a long period of time and the tile can be easily attached and detached at the time of repair or dismantling, and a dry tile construction method using the same. The purpose is.

Bracket rails for mounting tiles to achieve this purpose are the upper receiving part that supports the lower end of the tile and regulates the distance from the building skeleton by a certain distance or more, and the lower part that regulates the upper end side of the tile from the building skeleton by a certain distance or more. It is provided with a receiving portion, a rail main body that supports the upper receiving portion and the lower receiving portion and is attached to the building frame, and a horizontal spring portion that pushes the vicinity of the upper end of the tile forward from the back surface side of the tile.

Further, it is preferable that the lower receiving portion is provided with a vertical spring portion that presses the upper end of the tile to bring the lower end of the tile into close contact with the upper receiving portion of another tile mounting bracket.

Further, it is preferable that the horizontal spring portion is a claw having a spring property formed by cutting out a part of the rail body of the tile mounting bracket rail or a gasket separate from the rail body.

In addition, the vertical spring portion is a gasket that is separate from the claw or horizontal portion formed by cutting out a part of the horizontal portion that supports and supports the lower end of the tile in the upper receiving portion, and urges the upper end of the tile to be pushed down. It is preferable that it is a thing.

Further, the regulating portion of the lower receiving portion has a rear ridge line portion that contacts the surface of the upper end portion of the tile and a front ridge line portion that contacts the back surface of the lower end portion of the upper tile, and the upper end portion of the tile and the upper tile. The front and back movement between the upper tile and the lower tile is elastic by simultaneously contacting the front surface of the upper end of the tile and the back surface of the lower end of the upper tile with the lower end. The upper end of the tile is elastically sandwiched between the upper and lower tiles, and the movement in the front-back direction between the upper tile and the lower tile is moved horizontally with the lower and upper regulation parts. It is preferable that the tiles are elastically restrained in cooperation with the spring portion.

Further, in the method for constructing a dry tile according to the present invention, the tile mounting bracket rail according to claims 1 to 4 is horizontally placed on the vertical furring strip of the outer wall surface of the building frame or other base material at a predetermined interval in the vertical direction. The process of mounting multiple rows in the direction and the process of placing the lower end of the tile on the upper receiving part of the tile mounting bracket rail and sandwiching the upper end of the tile while crushing the horizontal spring part on the lower receiving part of the upper tile mounting bracket rail. For mounting the upper and lower tiles while elastically sandwiching the upper end of the tile between the regulating part of the lower receiving part and the horizontal spring part to prevent the tile from being lifted up due to frictional resistance. The tiles are locked between the bracket rails.

Here, the regulating portion of the lower receiving portion has a rear ridge line portion that contacts the surface of the upper end portion of the tile and a front ridge line portion that contacts the back surface of the lower end portion of the upper tile, and the lower end portion of the upper tile. With the front ridge supported by, the rear ridge is pressed against the front of the top of the tile at the same time, elastically restraining the back and forth movement between the upper and lower tiles and the horizontal spring. The upper end of the tile is elastically sandwiched between the parts, and the movement in the front-back direction between the upper tile and the lower tile is elastic by the cooperation of the lower regulation part, the upper regulation part, and the horizontal spring part. It is preferable that the tiles are supported.

Further, it is preferable that the surface of the tile to which the rear ridge line portion is pressed is a rough surface on which the rear side ridge line portion is caught, and a resistance against the movement of the rear side ridge line portion is given to brake the lifting movement of the tile.

Further, in the dry tile wall surface structure according to the present invention, a tile mounting bracket rail that is mounted in a plurality of rows in a horizontal direction at a predetermined interval in the vertical direction and an upper end portion and a lower end portion are attached to the tile mounting bracket rail. Bracket rails for mounting tiles, including the tiles to be held, support the lower end of the tile and regulate the distance from the building frame by more than a certain distance, and the upper end side of the tile from the building frame by more than a certain distance. It is provided with a lower receiving part, a rail body that supports the upper receiving part and the lower receiving part and attaches to the building frame, and a horizontal spring part that pushes the vicinity of the upper end of the tile forward from the back side of the tile to regulate the lower receiving part. The vicinity of the upper end of the tile is sandwiched between the portion and the horizontal spring portion and is elastically held, and the tile is engaged between the upper and lower tile mounting bracket rails while suppressing the tile from being lifted up due to frictional resistance. It is stopped to form the outer wall surface.

Here, the upper end and the lower end of the tile are provided with a portion that is hooked on the regulating portion of the upper receiving portion of the mounting bracket rail and the regulating portion of the lower receiving portion, and the regulating portion of the upper receiving portion of the tile mounting bracket rail is provided. It is preferable that the tile and the regulating portion of the lower receiving portion are hooked on the hooked portions at the upper end and the lower end of the tile to elastically hold the tile on the building frame.

Further, the regulating portion of the lower receiving portion of the tile mounting bracket rail has a rear ridge line portion that contacts the surface of the upper end portion of the tile and a front ridge line portion that contacts the back surface of the lower end portion of the upper tile, and has an upper portion. With the front ridge supported by the bottom of the tile, the rear ridge is simultaneously pressed against the front of the top of the tile, elastically moving back and forth between the top and bottom tiles. It functions as a restraint and elastically sandwiches the upper end of the tile between the horizontal spring part, and moves the upper tile and the lower tile in the front-back direction with the lower regulation part and the upper regulation part. It is preferable to elastically restrain the tile in cooperation with the horizontal spring portion.

According to the method for constructing the tile mounting bracket rail and the dry tile according to claim 1 and the dry tile wall structure, the upper receiving portion of the tile mounting bracket rail supports the lower end of the tile, while the lower receiving portion regulates the tile. Since the horizontal spring part holds the vicinity of the upper end of the tile, the tile can be fixed stably for a long period of time without deterioration over time like fixing with adhesive, and the tile can be easily fixed during repair or dismantling. Detachable from the tile mounting bracket rail.

Moreover, the tile mounting bracket rail can be easily mounted by fixing it to the base of the building frame or the furring strip with rivets or screws, and also with the regulation part of the lower receiving part of the tile mounting bracket rail on the upper stage. The tile can be fixed by simply fitting the lower end of the tile into the upper support of the tile mounting bracket rail on the lower stage while sandwiching the upper end of the tile between the horizontal springs, so workability of tile mounting work is improved. It will be improved.

In addition, the tile attached to the tile mounting bracket rail is pressed by the upper part of the tile being constantly sandwiched by the horizontal spring part that is pushed forward from the back side of the tile of the tile mounting bracket rail and the regulating part of the lower receiving part. Therefore, it is difficult to move even if an external force acts on the tile surface, and it is possible to obtain an excellent wall surface that does not generate noise or noise due to contact with the tile mounting bracket rail. That is, the mechanism of pushing the tile forward from the back surface side can prevent the tile from being lifted up due to frictional resistance.

Furthermore, since no adhesive is used to fix the tiles, not only can the tiles be easily attached to and detached from the tile mounting bracket rails during repairs and disassembly, but the tile mounting bracket rails and tiles can be easily separated again. It can be used.

If the bracket rail for mounting tiles of the present invention is further provided with a vertical spring portion that presses the tile from above, such as a claw or a gasket for pushing down the tile from above, it becomes more difficult to fall off and safety is enhanced.

Hereinafter, the configuration of the present invention will be described in detail based on the embodiments shown in the drawings. In this specification, the front-back, left-right directions are defined centering on the outer wall surface to which the tiles of the building frame are attached, and the "front" or "front" is the direction away from the outer wall surface, and the "back surface" or "Rear" is the direction closer to the outer wall surface. The horizontal direction is the left-right direction of the outer wall surface, and the vertical direction is the vertical direction along the outer wall surface. Further, the upper or lower tier is defined centering on the tiles to be inserted between the upper and lower arrangements of the horizontally arranged tile mounting bracket rail tiles, and the upper tile row is defined as the upper tier. The lower tile array is called the lower row.

FIG. 1 shows an example of an embodiment of a tile mounting bracket rail used in the dry tile construction method of the present invention. The tile mounting bracket rail 1 according to this embodiment has an upper receiving portion 7 that supports at least the lower end of the tile (that is, the lower edge) 22 and restricts the distance from the building frame by a certain distance or more, and the upper end of the tile (that is, that is). , Upper edge) 21 side is engaged so as to restrict the distance from the building skeleton by a certain distance or more. The lower receiving portion 6 and the rail body 4 that supports the upper receiving portion 7 and the lower receiving portion 6 and attaches to the building skeleton. A horizontal spring portion 8 that pushes the vicinity of the tile upper end 21 forward from the tile back surface side is provided, and the upper receiving portion 7, the lower receiving portion 6, the spring portion 8, and the rail body 4 are integrated. There is.

In addition, the tile mounting bracket rail of the present invention, the dry tile construction method using the same, and the dry tile wall structure are the tiles of the agreement (Aijakuri) (between the upper tile and the lower tile or the left and right tiles). It is suitable for applying to tiles in which the spaces are combined back and forth with each edge), but it is not necessarily applicable only to tiles that are in agreement, and at least the upper receiving part is at the end of the tile 20. Needless to say, it is applicable if there is a portion, for example, a groove that engages with the regulating portion 3 of 7 and the regulating portion 5 of the lower receiving portion 6. In the present specification, embodiments applied to the tiles of the agreement will be mainly described.

In the case of this embodiment, the tile mounting bracket 1 is integrally formed by continuously bending one metal plate. That is, the horizontal spring portion 8, the rail main body 4, the upper receiving portion 7, and the lower receiving portion 6 are configured like a single stroke by bending one metal plate. Here, the metal plate is not limited to a specific material, but for example, SUS304, which is also widely used as spring steel, other spring steel materials (SUP materials), and ZAM (hot dip galvanized aluminum / magnesium alloy plating). It is preferable to use a steel plate having high corrosion resistance that exhibits a certain degree of springiness, such as a steel plate / a registered trademark of Nittetsu Nissin Steel Co., Ltd.). This steel sheet has a thickness that combines ease of bending with strength that supports tiles and flexibility that exhibits springiness, for example, in the case of SUS304, about 0.3 mm to 1.0 mm, of ZAM (registered trademark). In some cases, it is preferably about 0.3 mm to 1.0 mm.

The upper receiving portion 7 is composed of a horizontal portion 2 that supports the lower end 22 of the tile and a regulating portion (hereinafter, referred to as an upper regulating portion 3) that regulates the tile so as not to be separated from the outer wall surface of the building frame more than a certain interval. .. Further, the lower receiving portion 6 is configured to include, for example, a regulating portion (hereinafter, referred to as a lower regulating portion 5) that bends the tip edge of the horizontal portion 2 downward. The lower receiving portion 6 is engaged with the tile in the front-rear direction and regulates so as not to be separated from the outer wall surface of the building frame more than a certain interval.

On the other hand, a spring portion 8 for urging the tile 20 from the back surface to the front surface is formed in the lower portion of the rail body 4. The spring portion 8 is formed by, for example, bending a part of the rail body 4 into a chevron shape.

Further, the tile mounting bracket rail 1 is not only formed of one metal plate as described above, but may also be formed of a plurality of plate materials. For example, as shown in FIG. 2, a spring portion 8, a rail body 4, a horizontal portion 2 constituting an upper receiving portion 7, and an upper regulating portion 3 are formed in a series by continuous bending with one metal plate. On the other hand, another metal plate may be crimped to the upper regulating portion 3 to form the lower receiving portion 6 and the lower regulating portion 5. In this case, the metal plate forming the spring portion 8, the rail body 4, and the upper receiving portion 7 requires rigidity, so that a thick metal plate is bent, but the bending angle is 90 ° at the maximum. Therefore, bending is easy. On the other hand, the metal plate forming the lower receiving portion 6 and the lower regulating portion 5 needs to be bent in the opposite direction, but the strength is ensured by superimposing them using a thin plate having a thickness of about half. Therefore, the bending process itself becomes easy. For example, 1 mm thick stainless steel is bent to continuously form the rail body 4, the claw-shaped spring portion 8, the receiving portion 2, and the upper regulating portion 3, while 0.5 mm stainless steel is folded back to form the upper regulating portion. The lower receiving portion 6 including the lower regulating portion 5 may be incorporated by covering and crimping the third. The lower receiving portion 6 is composed of a horizontal portion 2 and a lower regulating portion 5, and secures a space for accommodating the vicinity of the end portion including the upper end 21 of the tile.

Further, although not shown, in some cases, the rail body 4 and the upper receiving portion 7 (that is, the horizontal portion 2 and the upper regulating portion 3) are formed in a series by continuous bending with one metal plate. In advance, a spring portion 8, a rail body 4, and a lower receiving portion 6 (that is, a horizontal portion 2 and a lower restricting portion 5) are formed in a series by continuous bending with another metal plate. It may be integrated by welding, adhesion, rivet fastening, or the like, or it may be integrated by overlapping the four rail bodies and fixing them to the vertical furring strip or the base by the rivet 31 or the fastening screw.

As shown in FIG. 14, the tile mounting bracket rail 1 is provided so that the portion of the rail body 4 is directly mounted on the vertical furring strip 30 or the base by the rivet 31 or the fastening screw. The rail body 4 is provided with a hole 15 for passing a rivet or a screw. As shown in FIG. 5 or 7, for example, in the case of the long tile mounting bracket rail 1, the hole 15 has the pitch of the vertical furring strip 30 when, for example, the vertical furring strip 30 is arranged. By being provided at the same interval, or at least at both ends and in the center, consideration is given so that the vertical furring strip 30 or the base can be firmly attached. Further, in the case of a short tile mounting bracket rail 1 for example, a tile mounting bracket rail 1 for each tile, it is sufficient to provide the bracket rails 1 at both ends.

Further, since the regulating portion of the lower receiving portion 6, that is, the lower regulating portion 5 maintains the vicinity of the upper end 21 of the tile 20 with the horizontal spring portion 8 for pushing out the tile 20 from the back, it is preferable to enhance the spring property. .. For example, as shown in FIG. 3, the structure may be such that the tip end (lower end) side of the lower regulation portion 5 is offset (biased) toward the building skeleton side. In this case, the spring portion 8 having a right-angled triangle is not easily deformed, while the lower regulating portion 5 is easily deformed, so that the positioning and fixing of the tile 20 are more reliable.

Further, the upper regulation unit 3 and the lower regulation unit 5 are not limited to the case where they are continuously formed from end to end as shown in FIGS. 7 and 11, and are formed intermittently, for example, as shown in FIG. You may. In the case of the embodiment shown in FIG. 5, the upper regulation portion 3 and the lower regulation portion 5 are intermittently and alternately formed by alternately folding the tip edge of the horizontal portion 2 into a mountain fold and a valley fold by forming. ..

Further, in some cases, as shown in FIG. 2, FIG. 4 and FIG. 5, the spring portion 8 is formed from a side that is obliquely raised in a direction away from the building frame by, for example, valley folding the lower end edge of the rail body 4. It may be configured in the form of a claw. The spring portion 8 formed of the claws exerts springiness by pressing the tile 20 and crushing it toward the wall surface side. Further, as shown in FIGS. 6 and 7 or 8, the spring portion 8 may be configured as a claw whose lower end edge is folded back toward the lower receiving portion 6. The spring portion 8 composed of these claws may be continuously formed over the entire width of the tile mounting bracket rail 1, but in the case of the long tile mounting bracket rail 1, as shown in FIG. 7, it is intermittent. It may be formed in. As long as the tile 20 can be urged evenly, it does not matter whether it is continuous or intermittent.

Further, as shown in FIG. 3, the spring portion 8 may bend the lower end edge side of the rail body 4 into a right-angled triangular shape to support the back surface 26 of the tile. Further, the lower regulating portion 5 that regulates the front position of the tile on the surface side of the tile 20 is also a regulating plate by slightly bending the tip side inward to strengthen the structural springiness. The vicinity of the upper end of the tile may be pressed against the building frame side. Even in this case, the spring-like restricting plate and the folded-back portion can be fixed without rattling.

The spring portion 8 is not limited to the above-mentioned shape, for example, a claw that is folded back toward the lower receiving portion 6 so as to be inverted as shown in FIG. 6, or further separated from the tile 20 as shown in FIG. It is also possible to make the claws curved in the direction. In this case, for example, as shown in FIG. 16, even when an inclined surface exists on the convex side end portion 23 of the tile 20, the spring portion 8 abuts and pushes the tile 20 forward. It is possible to efficiently generate the force to force.

Further, as shown in FIG. 9 or FIG. 13, the spring portion 8 may be formed by a claw formed by cutting out a portion of the rail body 4 near the lower end edge. The claw-shaped spring portion 8 formed by cutting and raising is not limited to the one that is always arranged in the vertical direction, and may be arranged in the horizontal direction in some cases. For example, a U-shaped cutout causes U-shaped claws to be cut out side by side in the left-right direction. In this case, it is preferable that the lower end edge of the rail body is folded back to form the flange 14 so as to function as a spacer for restricting the position of the tile 20 toward the building frame side. At the same time, the flange 14 also functions as a rib, and the bending strength can be ensured.

Further, as shown in FIGS. 1 to 9 or 13, the spring portion 8 does not necessarily have to be formed by cutting out or bending a part of a metal plate, and is formed of another member, for example, a gasket 11 exhibiting rubber elasticity. You may. The gasket 11 is preferably a material exhibiting rubber elasticity excellent in durability, weather resistance, etc., and is not limited to a specific material, but more preferably, for example, ethylene propylene diene rubber (EPDM) is used. The shape of the gasket 11 is not limited to a specific one, but it is preferably a D-shaped cylinder having a flat surface portion as shown in FIG. 10, for example. In this case, the flat surface portion can be used as an adhesive surface and can be stably held by adhering to the metal plate / rail body 4 with an adhesive or an adhesive seal (not shown).

More preferably, the gasket 11 is provided with a claw 13 obtained by bending the lower end edge of the rail body 4 to form a flange 14 that also serves as a spacer, and a part of the rail body 4 is cut up, and a gasket is provided between the claw 13 and the flange 14. It is preferable to bond 11 with an adhesive or an adhesive tape to form a mounting structure that is difficult to peel off. Here, the height of the gasket 11 and the heights of the claw 13 and the flange 14 are higher than the height of the gasket 11, and the gasket 11 is crushed by coming into contact with the gasket 11 before the tile 20 hits the claw 13 and the flange 14. It is provided as follows.

The upper regulation part 3 and the lower regulation part 5 may be formed to have the same length (that is, height), but they do not have to be the same length, but rather the lower regulation part 5 is formed longer. Is preferable. For example, since the tile 20 is directly placed on the upper receiving portion 7, the position where the upper regulating portion 3 comes into contact with the tile 20 is naturally fixed and constant. That is, the upper regulation unit 3 can surely hit the tile. Further, when the tiles are loaded between the upper and lower tile mounting bracket rails 1, the tile lower end 22 must overcome the upper restricting portion 3 of the lower tile mounting bracket rail 1, so that the tiles are higher than necessary. Then it is not preferable. On the other hand, the lower regulation portion 5 is above the lower tile mounting bracket rail 1 when the tile is loaded between the upper end 21 of the tile to be fitted and the horizontal portion 2 which is the ceiling surface of the lower receiving portion 6. Since it is necessary to overcome the regulation unit 3, a gap for play is required. Then, after the tile 20 is loaded into the lower receiving portion 6, the lower end 22 of the tile is brought into close contact with the upper receiving portion 7 of the lower tile mounting bracket rail 1 and supported, so that the upper end 21 of the tile and the horizontal portion 2 are supported. Since a gap is generated again between the gaps, it is preferable that the lower regulating portion 5 is formed longer so that it can surely hit the tile.

Further, the upper regulation unit 3 and the lower regulation unit 5 are formed by being bent in opposite directions at the same position in the embodiment shown in FIGS. 1 to 12, but the upper regulation unit 3 and the lower regulation unit 5 are not particularly limited to this and are upwardly regulated. 3 and the downward regulating portion 5 facing downward may be formed at different positions as needed. For example, as shown in FIG. 13, the downward regulating portion 5 facing upward may be formed on the back side (that is, the wall surface side of the building frame) with respect to the upward regulating portion 3 facing upward. The offset upper and lower restricting portions 3 and 5 are suitable for application to tiles in which the upper end 21 of the tile and the lower end 22 of the tile have different engaging positions of the restricting portions 3 and 5 (see the lower portion of the tile in FIG. 15). Is. For example, since a gap 33 for avoiding interference is set between the convex side end portion 23 and the concave portion side end portion 24 of the tile that has been subjected to the phase-matching process, the downward regulating portion 5 facing downward is fitted. The grinding position or the position at the time of extrusion processing of the groove 27 to be fitted or the groove 25 to be fitted with the upward regulating portion 3 facing upward is appropriately set within the range of the gap 33. That is, the position of the groove 25 of the tile 20 is not limited to a specific position, and may be appropriately changed as necessary.

Further, the upper regulation portion 3 and the lower regulation portion 5 may be bent inward or outward to further enhance the springiness in the front-rear direction. For example, as shown in the tile mounting bracket rail 1 shown on the upper side of FIG. 19, the back side (that is, the building) including the portion where the upward regulating portion 3 is folded back and is continuous with the downward downward regulating portion 5. It may be formed so as to bulge toward the wall surface side of the skeleton) and the front side (that is, the side away from the wall surface of the building skeleton). The upper and lower restricting portions 3 and 5 spread in the front-rear direction between the convex side end portion 23 of the tile 20 and the concave portion side end portion 24 of the upper tile 20, for example, the upper tile. It acts to constrain the back and forth movement between the tile and the tile below. On the other hand, as shown in the tile mounting bracket rail 1 shown on the lower side of FIG. 19, the upper regulation portion 3 and the lower regulation portion 5 are the upper regulation portion 5 which extends downward and is folded back. The portion extending to the 3 side is abbreviated so as to incline to the back side (that is, the wall surface side of the building skeleton) and to the front side (that is, the side away from the wall surface of the building skeleton) again at the position of the upward regulating portion 3 facing upward. It may be formed so as to bulge in the shape of. Also in the upper and lower restricting portions 3 and 5, for example, a spring property that spreads in the front-rear direction between the convex portion side end portion 23 of the tile 20 that has undergone phase-matching processing and the concave portion side end portion 24 of the upper tile 20 is provided. As it presents, it functions to constrain the back and forth movement between the upper and lower tiles. If the vertical dimension of the tile becomes large, even if the upper side can be fixed, the lower side becomes unstable, and there is a risk that the tile will be retracted to the rear (building wall side). Therefore, in order to absorb the play between the upper tile and the lower tile and prevent rattling or retreat, the upper and lower regulation parts 3 and 5 themselves are angled to give a spring effect to the upper and lower tiles. By inserting it between the overlapping portions between the tiles, the back and forth movement of the upper tile and the lower tile can be restrained at the same time.

Further, as shown in FIG. 20, the lower regulating portion 5 of the lower receiving portion 6 is brought into contact with the front surface of the convex portion side end portion 23 of the tile 20 and the back surface of the concave portion side end portion 24 of the upper tile 20 at the same time. , The convex side end 23 of the tile 20 and the concave end 24 of the upper tile 20 spread in the front-rear direction, and the front-back movement between the upper tile 20 and the tile 20 is elastic. It may function to be constrained to. For example, as shown in FIGS. 20A and 20B, the lower regulating portion 5 is bent inward in the middle while bending a part of the tip edge of the horizontal portion 2 downward by forming processing or the like, and is near the tip edge again. Is folded outward and bulges outward in an abbreviated shape, and after contacting the front ridge line 28 that contacts the back surface of the concave end 24 of the upper tile 20 and the surface of the convex side end 23 of the tile 20. It is formed so as to include a side ridge line portion 29. The rear ridge line portion 29 is not necessarily required to be provided, but the tile 20 can be slid with respect to the surface of the convex portion side end portion 23 without being caught by the lower regulating portion 5, so that the tile 20 can be slid on the lower receiving portion 6. It is preferable to prevent it from becoming an obstacle when it is stored in the tile. On the other hand, a part of the tip edge of the horizontal portion 2 is bent upward to form the upper regulation portion 3.

On the other hand, the spring portion 8 pressed against the back surface of the tile 20 also bulges outward in an abbreviated shape and the vicinity of the tip edge is folded outward, similarly to the lower regulation portion 5. In the case of this spring structure, even if the normal spring bearing capacity is weak, the vertical furring strip is near the tip edge that is folded back when the tile is strongly pushed toward the building frame side and the spring portion 8 is deformed inward. By abutting on 30, it can function to increase the bearing capacity of the tile.

When the above-mentioned bracket rail 1 for mounting tiles is used, as shown in FIG. 21, the tile 20 is supported by the horizontal portion 2 of the upper receiving portion 7 and the lower apex 22 of the upper tile, and the rail. The tile 20 is held by the upper regulation portion 3 and the lower regulation portion 5 of 1, and the position in the front-rear direction is fixed. That is, the lower regulating portion 5 that bulges outward in an abbreviated shape urges the back surface of the concave end 24 of the upper tile 20 to be pushed forward, while the upper regulating portion 3 pushes the upper surface. Since the movement of the tile 20 to the front is restricted, the lower apex 22 portion of the upper tile 20 is positioned and held at a position corresponding to the upper restricting portion 3. On the other hand, the convex portion side end portion 23 inserted into the lower receiving portion 6 is elastically sandwiched and held by being pushed from the front by the lower regulating portion 5 and from the rear by the spring portion 8. Here, the lower regulating portion 5 simultaneously brings the front ridge line portion 28 and the rear ridge line portion 29 into contact with the front surface of the convex portion side end portion 23 of the tile 20 and the back surface of the concave side end portion 24 of the upper tile 20. The rear ridge line portion 29 of the tip is pressed against the front surface of the convex portion side end portion 23 while being supported by the concave end side end portion 24 of the upper tile. Therefore, the end portion of the tile 20, for example, the convex portion side end portion 23 can be elastically sandwiched and supported with the spring portion 8. In this way, the movement of the upper tile 20 and the lower tile 20 in the front-rear direction is restrained by the cooperation of the lower regulation portion 5, the upper regulation portion 3, and the spring portion 8, so that the upper tile 20 It is possible to absorb the play between the tile 20 and the tile 20 below and prevent rattling. Therefore, the tile 20 is held by a set of tile mounting bracket rails 1 that support the upper end and the lower end without rattling with respect to the vertical furring strip 4 or other base material at regular intervals.

Further, in the embodiment shown in FIG. 20, the upper regulation portion 3 and the lower regulation portion 5 are alternately formed as independent portions, but this is not essential, and as shown in FIG. 22, this is not essential. Needless to say, one spring material, for example, a spring steel plate, may be continuously bent from one end to the other of the rail.

In the case of the tile mounting bracket rail 1 of this embodiment as well, similarly to the tile mounting bracket rail 1 of the embodiment of FIG. 20, the tile 20 is provided by a set of tile mounting bracket rails 1 that support the upper end and the lower end. It is held without rattling at regular intervals with respect to the vertical furring strip 4 or other base material.

Further, the surface of the tile to which the rear ridge line portion 29 of the tip of the lower regulation portion 5 is pressed, for example, the surface of the convex portion side end portion 23 is roughened (provided with knurling) to form the regulation portion 5. It is preferable that the rear ridge line portion 29, that is, the claw is easily hooked. As the rough surface, for example, as shown in FIG. 24, a convex portion (in other words, a ginkgo leaf-shaped groove) 37 having a semicircular vertical cross section is preferably formed continuously. In this case, a braking mechanism can be configured between the convex portion (in other words, the leaf-shaped groove of the ginkgo tree) 37 and the rear ridge line portion 29 of the lower regulation portion 5. This braking mechanism gives resistance against the movement, and gives resistance so that the rear ridge line portion 29 of the lower regulation portion 5 is fitted into the groove between the convex portions 37 and the tile 20 is not lifted. , Suppresses the lifting of the tile 20. On the other hand, since the rear ridge line portion 29 allows the movement of the tile 20 by overcoming the convex portion 37, the movement of the tile 20 is allowed when a strong external force is applied, but the movement is blocked by the force of the spring otherwise. That is, it cannot be lifted. In the case of the wet manufacturing method in which the tile 1 is manufactured by extrusion molding, the uneven rough surface as illustrated in FIG. 24 is formed at the same time as extrusion, so that it becomes a groove / convex portion 37 penetrating in the extrusion direction. In the wet manufacturing method, a clay-like base material containing water is extruded into a plate shape by an extrusion molding machine and cut into a predetermined size to form a tile. Therefore, the convex portion (in other words, the groove) 37 is also arbitrary. The cross-sectional shape can be.

According to the tile mounting bracket rail 1 configured as described above, the tile lower end 22 is supported by the upper receiving portion 7 and is restricted from being separated from the building frame by a certain distance or more, while the tile upper end 21 side is restricted. The lower regulating portion 5 regulates the upper end side of the tile from being separated from the building skeleton by a certain distance or more, and the spring portion 8 as a horizontal spring portion that pushes the tile 20 forward (in the direction away from the building skeleton) from the back surface side of the tile 20. The front side of the tile 20 is pressed against the lower regulating portion 5 to give frictional resistance and prevent the tile 20 from being lifted. Further, according to the tile wall structure of FIGS. 21 and 23, the tile lower edge 22 is supported by the upper receiving portion 7 by the pair of tile mounting bracket rails 1 installed near the upper and lower ends of the tile 20. At the same time, the upper restricting portion 3 and the lower restricting portion 5 form the front surface of the convex side end portion 23 of the tile 20 and the back surface of the concave side end portion 24 of the upper tile 20 at the same time, The rear ridge line 29 at the tip of the lower regulation portion 5 supported by the concave end 24 of the upper tile is pressed from the front of the tile 20 by bringing the rear ridge 29 into contact with the spring portion 8. The end portion of the tile 20, for example, the convex portion side end portion 23, is elastically sandwiched and supported. Further, according to the tile wall surface structure of FIG. 24, the rear ridge line portion 29 of the lower regulation portion 5 is caught on the rough surface (convex portion 37) of the surface of the convex portion side end portion 23 of the tile, whereby the tile 20 is lifted. Is further blocked.

6 and 7 show other embodiments of the tile mounting bracket rails. The tile mounting bracket rail 1 is further provided with a vertical spring portion that presses the upper end 21 of the tile against the upper receiving portion 7 to prevent lifting. In the tile mounting bracket rail 1 of the present invention, the upper part of the tile is pushed from the back by the spring portion 8 and pressed against the lower regulation portion 5, so that the tile is prevented from being lifted by the frictional resistance generated. Therefore, by providing the vertical spring portion, it is possible to prevent the tile from being lifted more reliably.

The vertical spring portion is composed of, for example, a claw 9 having a spring property or a gasket 12 made of a rubber elastic material. In the case of the present embodiment, a claw 9 that is bent by cutting up a part of the horizontal portion 2 of the upper receiving portion 7 to form a claw 9 that protrudes toward the upper end 21 of the tile in advance, or after fitting the tile 20. It is integrally configured by providing. Of course, as with the horizontal spring portion 8 that pushes the back surface 26 side of the tile 20 forward, a rubber elastic material such as a gasket 12 may be interposed to urge the elastic force that constantly presses the tile upper end 21. good. As the rubber elastic material, not only an elastic material such as EPDM but also an adhesive material capable of retaining rubber elasticity such as an elastic adhesive may be used. Thereby, the rattling caused by the manufacturing error of the tile 20 can be absorbed.

The claw 9 as the vertical spring portion may be bent in advance, or may be bent after the tile is set. In the case of this embodiment, the claw 9 is formed by, for example, cutting up. For this reason, the claw 9 is cut up in the horizontal portion 2 and at the same time, a hole is formed thereafter, so that the claw 9 also serves as a draining hole. As a result, if there is rainwater flowing down the tile, it will fall down from the drain hole.

On the other hand, as shown in FIG. 10, when a gasket 12 of another member is used, the gasket 12 pressed against the upper end (koba) 21 of the tile 20 is pressed against and supported by the upper end 21 of the tile 20. Therefore, since the upper end 21 of the tile 20 is always supported, the gasket 12 is less likely to fall off even if the protective members such as the claws 13 and 14 are not present. Therefore, the gasket 12 can have a mounting structure that is difficult to peel off by simply adhering the gasket 12 with an adhesive or an adhesive tape.

The vertical spring portion composed of the claw 9 or the gasket 12 is deformed at the time of inserting the tile to facilitate the insertion of the tile 20, and after the insertion, the upper end 21 of the tile is pushed down and the lower end 22 of the tile is the lower tile mounting bracket rail. It is brought into close contact with the upper receiving portion 7 of 1. Therefore, the tile 20 is prevented from falling off. Further, since the vertical spring portion composed of the claw 9 or the gasket 12 has a spring property, even if the tile 20 moves upward, the tile 20 is immediately pushed down, so that the tile mounting bracket rail 1 below It won't come off.

The gaskets 11 and 12 may be used as a through material having a length corresponding to the entire width of the tile mounting bracket rail 1, but may be locally present as long as they are not unevenly distributed with respect to the tile 20. That is, the tiles 20 may be dispersedly arranged so that the back surface of the tiles 20 can be evenly pushed forward. Further, the gaskets 11 and 12 can be easily elastically deformed by, for example, having a hollow structure as shown in the drawing, but the gaskets 11 and 12 are not particularly limited to this, and may have a solid structure. ..

Further, the bracket rail 1 for mounting tiles of the above-described embodiment is composed of a bent product of a plate material such as stainless steel or ZAM (hot-dip zinc / aluminum / magnesium alloy plated steel plate / registered trademark of Nittetsu Nissin Steel Co., Ltd.). Although the above examples have been mainly described, the present invention is not particularly limited to this, and for example, an extruded product of an aluminum alloy may be used. In the case of an extruded aluminum product, it has less springiness than the above-mentioned metal plate and is formed with a thickness of, for example, about 1.5 mm, so that it is difficult to cut up a part to make a spring. By using the gaskets 11 and 12, it is provided so as to form a mechanism for urging the upper end 21 and the back surface 26 of the tile 20. For example, as shown in FIG. 12, it is preferable to fit the flange-shaped bases of the gaskets 11 and 12 by integrally molding the rectangular or groove-shaped engaging groove 10 at the time of extrusion processing. Here, in the case of an extruded aluminum product, it is easy to color it to an arbitrary color by alumite treatment or the like, so that it can be the same color as the tile 20. Therefore, as shown in FIG. 18, even if the end shape of the tile 20 is not fixed and the ends cannot be overlapped, the extruded aluminum product is colored in the same color as the tile, so that the tile is attached. Bracket rail 1 can be made inconspicuous.

The shape and end form of the tile 20 are not limited to a specific one, but at least the end of the tile 20 engages with the upper and lower restricting portions 3 and 5 of the upper receiving portion 7 and the lower receiving portion 6, respectively. It is desirable that there are irregularities and grooves, for example. For example, in the case of the present embodiment, as shown in FIGS. 14 to 16, the upper end side and the lower end portion of the tile 20 are formed into unevenness in which the upper end side and the lower end portion are combined with each other, that is, an unevenness called “aijakuri processing”. It is preferable to have. In the phase determination process, for example, as shown in FIG. 14, the upper end of the tile is a convex portion, and the lower end is a convex portion (roughly, hereinafter referred to as a convex side end portion 23). It is formed in each of the female seeds (aim, hereinafter referred to as the concave end side portion 24) to be the concave portion, and is used in combination so that the convex portion side end portion 23 overlaps the concave portion side end portion 24.

In the dry tile construction method using the above-mentioned bracket rail for mounting tiles and the dry tile wall structure, the tiles of the consensus (Aijakuri) (between the upper tile and the lower tile or between the left and right tiles, respectively. It is suitable for applying to tiles in which the edges are combined back and forth), but it is not necessarily applicable only to tiles that have a consensus, and at least at the end of the tile 20, the regulating part 3 of the upper receiving part 7 Needless to say, it is applicable if there is a portion that engages with the regulating portion 5 of the lower receiving portion 6, for example, a groove. Then, in the dry tile construction method and the dry tile wall surface structure according to the present embodiment, the tile mounting bracket rail 1 is previously mounted on the vertical furring strip of the building frame 21 or other base material, and the tile mounting bracket rail 1 is above the tile mounting bracket rail 1. The upper regulating portion 3 of the receiving portion 6 and the lower regulating portion 5 of the lower receiving portion 7 are hooked on the irregularities and grooves at the upper and lower ends of the tile, and the tile 1 as the outer wall material is attached to the building frame 21 to form the outer wall. It is a thing. That is, for example, as shown in FIGS. 14 to 17, the upper and lower restricting portions 3 and 5 are formed by providing the grooves 25 of one end portion of the phase determination process, for example, the convex portion side end portion 23 and the concave portion side end portion 24. It may be engaged by fitting, or as shown in FIG. 18, for example, by providing grooves 25 and 27 in the upper end 21 of the tile and the lower end 22 of the tile, respectively, the upper and lower restricting portions 3 and 5 are fitted. It may be engaged by matching.

Further, the tile 20 is not particularly limited in shape except for the portions that engage with the upper and lower regulating portions 3 and 5, and is hollow, solid wood, or the intermediate back surface side is scooped out. It is also possible if the back side of the corner is flat (vertical) or if it is tapered.

Next, the work procedure of the tile construction method using the tile mounting bracket rail 1 according to the present invention will be described.

First, the tile mounting bracket rail 1 is mounted directly on a base (not shown) of the outer wall of the building frame or by interposing a vertical furring strip, and the tile mounting bracket rail 1 is mounted at a predetermined position by marking or the like, for example, by riveting or screwing. For example, as shown in FIG. 21 or FIG. 23, the vertical furring strip 30 is placed on the outer wall of the building frame 36 at a predetermined position by marking or the like at a predetermined pitch, for example, the height-adjustable bolts 33 and nuts 34, Install at 35. The vertical furring strip 30 is, for example, a hat-shaped steel plate, and the anchor nut 32 for concrete is driven into the building frame 36 and then sandwiched between the adjusting bolt 33 and the two nuts 34 and 35 to adjust the non-landing. I try to fix it on the top. The required number of tile mounting bracket rails 1 are arranged at predetermined intervals in the vertical and horizontal directions.

Next, the upper and lower tile mounting bracket rails 1 are set as a set, and the tile 20 is inserted between them to mount the tile 20. The tiles 20 are mounted side by side from bottom to top. For example, in the case of the tile of FIG. 14, the convex side end portion 23 of the tile 20 is attached to the lower receiving portion 6 of the upper tile mounting bracket rail 1 with the spring of the horizontal spring portion 8 of the tile mounting bracket rail 1 and the lower receiving portion. Push the tile 20 diagonally into the space between the lower part 6 and the lower part 5 and lift the tile 20 in that state to place the upper part 3 of the upper part 7 of the lower tile mounting bracket rail 1 on the tile lower end 22. After getting over it, the tile lower end 22 is fitted into the upper receiving portion 7 of the lower tile mounting bracket rail 1 by dropping it. This tile mounting work can be carried out extremely easily and quickly. Then, the lower end 11 of the tile 20 is supported and locked by the tile mounting bracket rail 1 by fitting by dropping. At the same time, the upper end 21 of the tile 20 is sandwiched and pressed by the horizontal spring portion 8 that pushes forward from the back surface side of the tile 20 of the upper tile mounting bracket rail 1 and the lower regulation portion 5 of the lower receiving portion 6. Can be attached.

In the same manner, the tiles 20 are assembled side by side in order. After the installation is completed, move to the upper stage. When tiles are sequentially attached to the upper tile mounting bracket rail 1 in the same procedure, the front hanging portion 24 of the attached tile is weighted toward the front side of the step portion 23 of the lower tile 20, so that the tile mounting bracket rail 1 Shield the part fixed with. Then, the tile 20 is firmly fixed by the tile mounting bracket rail 1.

The tiles to be loaded between the set of tile mounting bracket rails 1 have the tile lower end 22 supported by the upper receiving portion 7 of the lower tile mounting bracket rail 1, and the upper tile mounting bracket rail. The vicinity of the upper end 21 of the tile is held by the lower receiving portion 6 of 1, and the position is restricted so as not to be separated from the building skeleton by a certain distance or more, and the tile is attached to the building skeleton. Then, it is difficult to move even if an external force acts on the tile 20, and it is possible to obtain an excellent tile outer wall surface that does not generate noise or noise due to contact with the tile mounting bracket rail 1. That is, the horizontal spring portion 8 can prevent the tile 20 from being lifted up due to frictional resistance. Further, if the claw 9 or the gasket 12 forming the vertical spring portion for pushing down the tile 20 from above is provided, the safety is further enhanced. Further, the tile 20 is held by the tile mounting bracket rail 1 so as not to fall off, but since it is not fixed to the tile mounting bracket rail 1, the tile mounting bracket rail 1 expands and contracts due to a change in the outside air temperature. However, no external force is applied to the tile 20.

The above-described embodiment is an example of a preferred embodiment of the present invention, but the present invention is not limited to this, and various modifications can be performed without departing from the gist of the present invention. For example, the above-described embodiment has been mainly described by giving an example of mounting the rail on the base material of the building frame via the furring strip, but the present invention is not particularly limited to this, and the tile mounting bracket is directly screwed to the base material. The rail 1 may be fixed.
