However, in the conventional carnival method, especially when the tile is made of pottery, the longer the width of the tile, the greater the warp that occurs when the tile is baked, and the rail does not fit in the back foot or rattles. May occur. Further, in the invention described in Patent Document 1, a metal fitting is attached to the back foot of the tile in advance and the metal fitting is fitted to the rail. However, if the warp of the tile itself becomes large, the position of the metal fitting also shifts. There is a possibility that it will not fit the rail.

Therefore, an object of the present invention is to provide a metal fitting for a back foot that can be locked by following the warp of a tile when the tile is dry-attached to the outer wall of a building.

In order to solve the above problems, the tile back foot metal fitting of the present invention has a vertically long self-weight receiver in which a plurality of tiles are intermittently arranged in the lateral direction so as to pass from the upper end to the lower end of the base material. A metal fitting and a horizontally long base metal fitting in which a plurality of pieces are intermittently locked to the self-weight receiving metal fitting in the vertical direction so as to pass from the left end to the right end of the base material are provided, and the base metal fitting is a tile. A plurality of upper locking pieces for hooking on the upper back of the back foot and lower locking pieces for hooking on the lower back of the back foot of the tile are intermittently formed in the lateral direction, and the upper locking pieces are formed. Each piece flexes independently so that it evenly contacts the hind legs in accordance with the warp of the tile.

In the metal fittings for the back legs of the tile, the base metal fittings are vertically locked from the middle front plate on the front surface in which the upper and lower face plates are projected forward so as to enter the back legs from the upper and lower rear plates that are in contact with the self-weight receiving metal fittings. A piece is cut out, and in the upper locking piece, the upper spring portion cut to the upper surface plate bends, so that the upper folding portion folded upward from the middle front plate is caught by the back foot and the lower locking piece is engaged. The piece is characterized in that the lower folded portion, which is shorter than the upper folded portion and is folded downward from the middle front plate, is caught on the back foot.

In the metal fittings for the back legs of the tile, the self-weight receiving metal fittings are characterized in that a plurality of upper and lower hooks are intermittently formed in the vertical direction so as to sandwich the upper and lower rear plates from above and below.

According to the present invention, when a tile is dry-attached to the outer wall of a building, it can be locked by following the warp of the tile.

FIG. 2 is an enlarged front view, (b) plan view, and (c) side view of a part of the skeleton to which tiles are attached by using the back foot metal fittings. FIG. 3 is (a) a front view, (b) a plan view, and (c) a side view showing the metal fittings for the back legs of the tile. FIG. 4 is a perspective view showing a metal fitting for the back foot of the tile.

In the front views of FIGS. 1 (a) and 2 (a), the tiles are shown in a transparent state. Further, in the front view, the front side is the front (front) and the back side is the back (back).

As shown in FIG. 1, the outer wall of the building is finished by attaching a tile panel to the skeleton 100 via the furring strip 110 or the like. The skeleton 100 is a frame that supports a building structure, and includes a wooden structure, a steel frame structure, and an RC (reinforced concrete) structure. The furring strip 110 is a member for fixing the tile panel to the skeleton 100 in a dry manner. For example, vertically extending C-shaped steel (C channel) or the like is intermittently arranged in the lateral direction at predetermined intervals. It also improves breathability.

A plurality of tiles 130 are attached to the tile panel using the back foot metal fittings on the base material 120. As the base material 120, a flexible board (a non-combustible board made of cement and reinforcing fibers as raw materials) or the like is used, and the base material 120 is fastened to the furring strip 110 with a base screw 150 or the like. Further, the back foot metal fitting is fastened to the furring strip 110 by penetrating the base material 120 with the screw 140.

The tile 130 is a finishing material for decorating the outer wall of a building, and is made of plate-shaped ceramics or the like, and has back legs (ant legs) on the back surface for improving adhesiveness. The back foot is formed with irregularities in an inverted C shape like an ant's foot. For example, when one back foot is formed on the horizontally long tile 130, the back foot metal fittings may be locked at intervals of the vertical width of the tile 130. It should be noted that the upper end of the lower tile 130 may be overlapped with the lower portion of the upper tile 130 so as to slip into the lower portion. Further, when a gap such as a joint is provided between the tile 130 and another tile 130 adjacent to the side, a joint material 160 such as mortar may be filled.

The back foot metal fittings are vertically long self-weight receiving metal fittings 200 in which a plurality of metal fittings are intermittently arranged in the lateral direction so as to pass from the upper end to the lower end of the base material 120, and pass from the left end to the right end of the base material 120. A plurality of horizontally long base metal fittings 300 are intermittently locked to the self-weight receiving metal fittings 200 in the vertical direction.

As shown in FIG. 2, in the self-weight receiving metal fitting 200, the upper hook 210 and the lower hook 220 are intermittently formed in the vertical direction at each position (interval) in which the plurality of base metal fittings 300 are locked. For example, the upper hook 210 may be provided with a downward claw, and the lower hook 220 may be provided with an upward claw to support the base metal fitting 300 so as to sandwich it from above and below.

The self-weight receiving metal fitting 200 is fixed to the base material 120, and the base metal fitting 300 is supported by the self-weight receiving metal fitting 200. In order to fasten the self-weight receiving metal fitting 200 to the base material 120 with the screw 140, a plurality of horizontally long loose holes 230 may be intermittently opened in the vertical direction.

The base metal fitting 300 is fitted to the back foot of the tile 130. In addition, since the tile 130 may be warped and the degree of hooking of the base metal fitting 300 differs for each portion, a filler 170 such as an elastic adhesive may be filled in the gap in order to improve the adhesiveness.

As shown in FIGS. 3 and 4, in the base metal fitting 300, the upper surface plate 320 and the lower surface plate 340 are projected forward so as to enter the back legs from the upper rear plate 310 and the lower rear plate 350 that are in contact with the self-weight receiving metal fitting 200. The upper locking piece 360 and the lower locking piece 370 are cut out from the middle front plate 330 on the front surface. The upper rear plate 310 and the lower rear plate 350 are sandwiched between the upper hook 210 and the lower hook 220 of the self-weight receiving metal fitting 200.

In the upper locking piece 360, the upper spring portion 360a cut into the upper surface plate 320 bends, so that the upper folding portion 360b folded upward from the middle front plate 330 is caught on the back foot, and the lower locking piece 370 is in the middle. The lower folded portion 370a, which is shorter than the upper folded portion 360b and folded downward from the front plate 330, is caught on the back foot.

In the base metal fitting 300, the upper locking piece 360 for hooking on the upper back of the back foot of the tile 130 and the lower locking piece 370 for hooking on the lower back of the back foot of the tile 130 are intermittent in the lateral direction. Multiple tiles are formed. By flexing the upper locking pieces 360 independently, the upper locking pieces 360 are evenly contacted with the back legs according to the warp of the tile 130.

In the upper locking piece 360, a notch 320a is made from the middle front plate 330 to the upper surface plate 320, and the vicinity of the folds of the middle front plate 330 and the upper surface plate 320 is folded back in reverse to provide the upper folding portion 360b. An upper hole 330a is formed in the 330, and an upper spring portion 360a is formed in the upper surface plate 320. Further, in the lower locking piece 370, the lower part of the middle front plate 330 is cut, and the vicinity of the folds of the middle front plate 330 and the lower surface plate 340 is folded back in reverse to provide the lower folded portion 370b, so that the lower part of the middle front plate 330 is lowered. Hole 330b is formed.

When the notch 320a does not reach the crease between the upper rear plate 310 and the upper surface plate 320, the elastic force of the upper spring portion 360a becomes stronger and is pressed against each part of the back foot. The middle front plate 330 is formed in a size that fits into the opening of the back foot, the lower folded portion 370b is formed in a length that reaches the lower back of the back foot, and the back is in a state where the upper spring portion 360a is urged. The upper folded portion 360b may be formed so as to reach the upper back of the foot.

According to the present invention, when a tile is dry-attached to the outer wall of a building, it can be locked by following the warp of the tile.

Examples of the present invention have been described above, but the present invention is not limited thereto.
