However, the above-mentioned adhesive pasting method has a problem that work for adjusting (suppressing) the unevenness of the base surface is required. Further, in the above-mentioned hooking method, there is a problem that rainwater easily infiltrates when an empty joint is adopted in which there is no overlapping allowance between adjacent tiles and a gap between joints is left between the tiles. Further, the tiled outer wall structure of Patent Document 1 has an advantage that rainwater does not easily infiltrate even in empty joints because there is a stacking allowance between adjacent tiles, but the outer wall tile material is used with a fixture (screw nail). Since the structure is fixed to the outer wall surface, the unevenness of the outer wall base is easily reflected, and there is a drawback that the finished surface of the outer wall tile is difficult to be flattened.

In view of the above circumstances, it is an object of the present invention to provide a tiled outer wall structure capable of forming a flat outer wall tile finished surface as much as possible by reducing the influence of non-landing of the outer wall base, which makes it difficult for rainwater to enter even in open joints. And.

In the tiled outer wall structure of the present invention, in order to solve the above-mentioned problems, an engaging protrusion having a neck portion and a head larger than the neck portion is provided on the back surface on the upper side of the outer wall tile, and the outer wall is described above. The outer wall base to which the tile is attached is provided with a recess in which the engaging protrusion is hung, and at least the upper side of the outer wall tile is covered with another outer wall tile provided on the upper side.

With the above configuration, the outer wall tile is attached to the outer wall base by hooking the engaging protrusions provided on the back surface on the upper side of the outer wall tile into the recess. That is, the outer wall tile is not fixed to the outer wall base with screws or the like, and positional flexibility (degree of freedom) can be obtained. Therefore, the influence of the non-landing of the outer wall base is reduced to form the outer wall tile finished surface as flat as possible. It becomes easy. Further, since at least the upper side of the outer wall tile is covered with other outer wall tiles provided on the upper side, it is difficult for rainwater to enter even if the joints of the upper and lower outer wall tiles are empty joints. Of course, if the tiles are overlapped not only on the upper side but also on the left and right sides, rainwater will not easily enter even if the joints of the outer wall tiles arranged on the left and right are empty joints.

A receiving member is mounted in the recess, and the head accommodating portion in which the head of the engaging protrusion is housed and the neck of the engaging protrusion are slid downward in the receiving member. A neck accommodating portion may be formed. According to this, since the load due to the outer wall tile is not directly applied to the recess, but is applied to the recess via the receiving member, it is possible to suppress chipping of the recess.

A plate-shaped member may be provided on the base of the outer wall, and a hole through which the engaging protrusion may be passed may be formed at a corresponding portion of the plate-shaped member where the recess is located. According to this, the outer wall tiles are arranged with reference to the surface position of the plate-shaped member. Since it is easy to form the surface of the plate-shaped member flatter than the surface of the outer wall base, it becomes easy to form a flat outer wall tile finished surface. Further, there is an advantage that the outer wall base is reinforced by the plate-shaped member.

An insertion portion through which the head of the engagement protrusion can be inserted is formed on the upper side of the hole, and the neck of the engagement protrusion can be slid downward on the lower side of the hole. A slide portion may be formed. According to this, the hole portion has a portion similar to the neck portion accommodating portion, and the outer wall tile can be supported more firmly.

A plurality of the plate-shaped members are provided at intervals in the horizontal direction, and each plate-shaped member may be formed with a plurality of rows in which the holes are vertically arranged at predetermined intervals. According to this, for example, one row of the plurality of rows is used for the engaging protrusions of the outer wall tiles on one side arranged adjacent to each other in the horizontal direction, and the engaging protrusions of the outer wall tiles on the other side are used. The exterior wall tiles can be attached using other rows for the part. Further, a gap corresponding to the plate thickness of the plate-shaped member is formed between the outer wall tile arranged horizontally between the horizontally adjacent plate-shaped members and the outer wall base, and rainwater is drained by this gap. can do.

The plate-shaped members are provided on both the left and right sides of the vertical joints so as not to block the vertical joints formed between the outer wall bases adjacent to the left and right, and the outer wall tiles are provided so as to close the vertical joints. It may be. According to this, even if there is some movement in and out of the outer wall bases adjacent to the left and right, the outer wall tiles are not fixed to the outer wall bases with screws or the like, and positional flexibility can be obtained. It can be attached, and the unevenness caused by the slight entry and exit of the outer wall bases adjacent to the left and right can be made inconspicuous. Further, the outer wall bases adjacent to the left and right may shift due to an earthquake or the like, but as described above, the outer wall tiles are not fastened to the outer wall base with screws or the like, and positional flexibility is obtained. Therefore, it is unlikely to be an obstacle to the in-plane displacement movement of the outer wall base, and the cracking of the outer wall tile due to the out-of-plane displacement movement can be reduced.

The plate-shaped member is provided so as to be continuous up and down so as not to block the horizontal joints formed between the outer wall bases arranged above and below, so that the outer wall tiles close the horizontal joints. It may be provided. According to this, even if there is some movement in and out of the outer wall bases arranged above and below, the outer wall tiles are not fixed to the outer wall bases with screws or the like, and positional flexibility can be obtained. It is possible to attach tiles, and it is possible to make the unevenness due to the slight entry and exit of the outer wall bases arranged above and below inconspicuous. Further, similarly to the above, since the outer wall tile is not fastened to the outer wall base with screws or the like and has a positional flexibility, it is unlikely to be an obstacle to the in-plane displacement movement of the outer wall base. In addition, cracking of the outer wall tile due to the displacement movement in the out-of-plane direction can be reduced.

According to the present invention, the outer wall tile is not fixed to the outer wall base with screws or the like, and the influence of the non-landing of the outer wall base can be reduced to form a flat outer wall tile finished surface as much as possible.

It has a head that has a truncated cone shape (smaller diameter toward the neck side). In this embodiment, a large-diameter portion having substantially the same shape as the head is formed at the end of the engaging protrusion 11 opposite to the head, and this large-diameter portion is formed on the upper side 1a. The large-diameter portion is exposed to the surface side of the above, and the large-diameter portion is fixed to the neck portion (shaft portion) and the upper portion 1a by, for example, an adhesive. Of course, the large diameter portion may be fixed to the neck portion (shaft portion) and the upper portion side 1a by caulking or the like instead of an adhesive.

A receiving member 25 is mounted in the recess 20a. The receiving member 25 is made by processing a metal plate, for example, and is hollow and has a substantially truncated cone shape. The receiving member 25, which is inserted from the upper side of the recess 20a and is located on the bottom side of the lower portion of the recess 20a, is in a state where it is difficult to separate from the recess 20a by the wall portion. Further, as shown in FIGS. 4 (A) and 4 (B), the receiving member 25 includes a head accommodating portion 25a in which the head of the engaging protrusion 11 is accommodated and the engaging protrusion 25 a. A head accommodating portion 25b is formed in which the neck portion of 11 can be slid downward to support the neck portion. A notch for inserting the head of the engaging protrusion 11 is formed on the upper side of the neck accommodating portion 25b.

As shown in FIGS. 5 (A), 5 (B) and 5 (C), a plate-shaped member 5 made of a steel plate is attached to the outer wall base 20 with an adhesive or the like. A hole 51 through which the engaging protrusion 11 is passed is formed at a corresponding portion of the plate-shaped member 5 where the recess 20a is located. The plate-shaped member 5 is made of, for example, a steel plate having a plate thickness of about 1.6 mm.

As shown in FIG. 6, a substantially circular insertion portion 51a through which the head of the engaging protrusion 11 can be inserted is formed on the upper side of the hole 51, and the lower side of the hole 51 is formed with the above. A substantially U-shaped slide portion 51b is formed so that the neck portion of the engagement protrusion 11 can be slid downward. That is, the hole 51 has a portion similar to that of the neck accommodating portion 25b of the receiving member 25. Of course, the hole 51 may be formed in a large circular shape so as to include the head accommodating portion 25a of the receiving member 25.

A plurality of the plate-shaped members 5 are provided at intervals in the horizontal direction, and each plate-shaped member 5 is formed with two rows in which the holes 51 are vertically arranged at predetermined intervals. Then, one of the two rows is used for the engaging protrusion 11 of the outer wall tile 1 on one side arranged adjacent to each other in the horizontal direction, and the engaging of the outer wall tile 1 on the other side is used. The outer wall tile 1 is attached using another row for the protrusion 11. Further, a gap corresponding to the plate thickness of the plate-shaped member 5 is formed between the outer wall tile 1 arranged horizontally between the plate-shaped members 5 adjacent to each other and the outer wall base 20.

The plate-shaped member 5 is provided on both the left and right sides of the vertical joint 28 so as not to block the vertical joint 28 formed between the outer wall bases 20 adjacent to the left and right, and the outer wall tile 1 is the vertical joint. It is provided so as to block 28.

Further, the plate-shaped member 5 is provided so as to be continuous vertically so as not to block the horizontal joints 29 formed between the outer wall bases 20 arranged vertically, and the outer wall tile 1 is described above. It is provided so as to close the horizontal joint 29.

An outer wall tile 1C having an L-shaped cross section is attached to a protruding corner of the outer wall. Then, the outer wall tile 1B is attached between the outer wall tile 1C and the outer wall tile 1. The outer wall tile 1B has a shorter width than the outer wall tile 1. Further, corresponding to this width, the distance between the two plate-shaped members 5 provided near the protruding corner is also narrowed.

In the above configuration, the outer wall tile 1 is attached to the outer wall base 20 by hanging the engaging protrusion 11 provided on the back surface of the upper side 1a of the outer wall tile 1 on the recess 20a. Become. That is, the outer wall tile 1 is not fastened to the outer wall base 20 with screws or the like, and positional flexibility (degree of freedom) can be obtained. Therefore, the influence of the non-landing of the outer wall base 20 is reduced and the outer wall tile finish is as flat as possible. It becomes easy to form a surface. Further, since the upper side 1a of the outer wall tile 1 is covered with another outer wall tile 1 provided on the upper side and the protrusion 12 and the recess 13 overlap each other, even if the joints of the outer wall tiles 1 arranged vertically are empty joints. It is difficult for rainwater to enter.

A receiving member 25 is mounted in the recess 20a, and the head accommodating portion 25a in which the head of the engaging protrusion 11 is housed and the neck portion of the engaging protrusion 11 are mounted on the receiving member 25. A neck housing portion 25b that can be slid downward may be formed. According to this, since the load due to the outer wall tile 1 is not directly applied to the recess 20a but is applied to the recess 20a via the receiving member 25, it is possible to suppress chipping of the recess 20a.

A plate-shaped member 5 is attached to the outer wall base 20, and a hole 51 through which the engaging protrusion 11 is passed is formed at a position where the recess 20a of the plate-shaped member 5 is located. May be good. According to this, the outer wall tile 1 is arranged with reference to the surface position of the plate-shaped member 5. Since it is easier to form the surface of the plate-shaped member 5 flatter than the surface of the outer wall base 20, it becomes easier to form a flat outer wall tile finished surface. Further, there is an advantage that the outer wall base 20 is reinforced by the plate-shaped member 5.

An insertion portion 51a through which the head of the engagement protrusion 11 can be inserted is formed on the upper side of the hole 51, and the neck portion of the engagement protrusion 11 is downward on the lower side of the hole 51. A slide portion 51b that can be slid may be formed. According to this, the hole 51 has a portion similar to the neck accommodating portion 25b of the receiving member 25, and the outer wall tile 1 can be supported more firmly.

When a plurality of the plate-shaped members 5 are provided at intervals in the horizontal direction, and each plate-shaped member 5 is formed with two rows in which the holes 51 are vertically arranged at predetermined intervals. One of the above two rows is used for one engaging protrusion 11 of the outer wall tile 1 on one side arranged adjacent to each other in the horizontal direction, and one engagement of the outer wall tile 1 on the other side is used. The outer wall tile can be attached using another row for the protrusion 11. Further, a gap corresponding to the plate thickness of the plate-shaped member 5 is formed between the outer wall tile 1 and the outer wall base 20 arranged between the horizontally adjacent plate-shaped members 5, and the gap causes the gap. Rainwater can be drained.

The plate-shaped member 5 is provided on both the left and right sides of the vertical joint 28 so as not to block the vertical joint 28 formed between the outer wall bases 20 adjacent to the left and right, and the outer wall tile 1 is the vertical joint. If it is provided so as to block 28, the outer wall tile 1 is not fixed to the outer wall base 20 with screws or the like even if the outer wall bases 20 adjacent to the left and right have some in and out, and the position flexibility is improved. Since it has been obtained, it is possible to attach the outer wall tile 1, and it is possible to make the unevenness due to the fact that the outer wall bases 20 adjacent to the left and right are slightly in and out. Further, the outer wall bases 20 adjacent to the left and right may shift due to an earthquake or the like, but the outer wall tile 1 is not fixed to the outer wall base 20 with screws or the like, and positional flexibility is obtained. Therefore, it is unlikely to be an obstacle to the in-plane displacement movement of the outer wall base 20.

The plate-shaped member 5 is provided so as to be continuous vertically so as not to block the horizontal joints 29 formed between the outer wall bases 20 arranged above and below, and the outer wall tile 1 is provided with the horizontal joints 1. If the tiles 1 are provided so as to block the 29, the outer wall tile 1 is not fixed to the outer wall base 20 with screws or the like even if the outer wall bases 20 arranged above and below have some ingress and egress, and the tiles 1 are not fixed to the outer wall base 20 by screws or the like, and are positionally flexible. Therefore, it is possible to attach the outer wall tile 1 and to make the unevenness due to the slightly coming and going of the outer wall base 20 adjacent to the upper and lower sides inconspicuous. Further, similarly to the above, since the outer wall tile 1 is not fixed to the outer wall base 20 with screws or the like and has a positional flexibility, it is an obstacle to the in-plane displacement movement of the outer wall base 20. It is hard to become.

In the above example, the adhesive is not used at all, but the present invention is not limited to this. For example, the head of the engaging protrusion 11 is the head accommodating portion 25a of the receiving member 25. An adhesive may be used so that the adhesive is fixed inside.

Although the embodiments of the present invention have been described above with reference to the drawings, the present invention is not limited to those of the illustrated embodiments. Various modifications and modifications can be made to the illustrated embodiment within the same range as the present invention or within the same range.
