  Embodiments of the present invention will be described below with reference to the drawings.

  As shown in FIGS. 1 and 2, the tile support method for the building outer wall according to the present embodiment is a tile cassette in which the tile 1 is held by the tile holding frame 2 in the space constituting the finished surface using the tile 1. 3 and a plurality of tile cassettes 3 are sequentially attached (stacked) to the front surface of the base frame 4 so as to be continuous from the bottom to the top.

  Here, the tile cassette 3 is in a state in which the tile 1 and the tile holding frame 2 are bonded to each other by the elastic adhesive 5 and the tile holding frame 2 holds the tile 1 as shown in the encircled line in FIG. It is comprised as follows.

  Specifically, as shown in FIGS. 1, 3A and 3B, the tile 1 has a horizontally long plate shape, and grooves 6 and 7 are formed on the upper end surface and the lower end surface thereof, respectively. On the other hand, the tile holding frame 2 is made of an aluminum extruded profile, and has a downward claw 8 fitted in the upper groove 6 of the tile 1, a main body 9 that contacts the back surface (back surface) of the tile 1, and the tile. 1 has a receiving portion 11 that contacts the heel portion 10 on the rear side of the lower groove 7 and a bridge portion 12 that connects the downward claw 8 and the main body portion 9.

  Then, as shown in the encircled line in FIG. 1, the elastic adhesive 5 is applied to a region (see the broken line portion in the same figure) from the inside of the upper groove 6 on the outer surface of the tile 1 to the heel portion 10 through the back surface. Applying, the downward claw 8 of the tile holding frame 2 is fitted into the groove 6 on the upper side of the tile 1, the back surface of the tile 1 is brought into contact with the front surface of the main body 9 of the tile holding frame 2, and the heel of the tile 1 The tile cassette 3 can be obtained by bringing the portion 10 into contact with the receiving portion 11 of the tile holding frame 2 and bonding the tile 1 and the tile holding frame 2 together. The fitting of the tile 1 into the tile holding frame 2 does not need to be performed by sliding the tile 1 from the left and right ends of the tile holding frame 2, and can be performed from the front of the tile holding frame 2.

  In addition, as shown in FIG. 1, in the tile holding frame 2, an upward claw 13 extending upward is connected to the upper end portion of the downward claw 8 or the front end portion of the bridge portion 12. The nail | claw 13 is comprised so that it can insert in the groove | channel 7 below tile 1 when the several tile cassette 3 is laminated | stacked up and down.

  On the other hand, as shown in FIG. 2 and FIG. 3A, the base frame 4 is made of, for example, a hollow shape member made of aluminum, and is attached to a building frame outside the figure. A unit (outer wall unit) is formed.

  Next, a procedure for attaching the plurality of tile cassettes 3 to the base frame 4 will be described together with a more detailed description of each configuration of the tile cassette 3 and the base frame 4.

  First, the tile cassette 3 is attached to the lowermost part of the base frame 4. Specifically, first, as shown in the lower part of FIG. 2, the upward claw 13 provided at the lowermost part of the base frame 4 is fitted into the groove 7 on the lower side of the tile 1 in the tile cassette 3, A downward engaging piece 15 provided on the back side of the main body portion 9 of the tile holding frame 2 in the tile cassette 3 is engaged with the rear side of the upward engaging piece 14 provided in the lowermost part of the base frame 4. In this state, the upward extension 17 (see FIG. 1) connected to the upper end of the main body 9 of the tile holding frame 2 via the backward bridge 16 is connected to the bolt (for example, the bolt 18 and the locking function). It fixes to the front part of the base frame 4 by the joining using the U nut (brand name) 19 which has.

  Here, when performing a bolting operation on the upward extension 17 of the tile holding frame 2, it is preferable that the upward claws 13 of the tile holding frame 2 do not interfere with the bolting operation. The portion 17 may be extended upward from the upward claw 13 so that the bolting operation can be performed on a portion of the upward extension portion 17 positioned above the upward claw 13.

  Subsequently, another tile cassette 3 is attached on the upper side of the tile cassette 3 attached to the base frame 4. That is, as shown in the lower part of FIG. 2, the upward claws 13 provided in the tile holding frame 2 in the tile cassette 3 attached to the lowermost part of the base frame 4 are set as attachment targets (new attachment It fits into the lower groove 7 of the tile 1 in the tile cassette 3 and is continuously provided above the upward extension 17 of the tile holding frame 2 in the tile cassette 3 attached to the lowermost part of the base frame 4. Further, the downward engaging piece 15 provided on the back side of the main body 9 of the tile holding frame 2 constituting the tile cassette 3 to be attached is engaged with the rear side of the upward engaging piece 14. In this state, the upward extension 17 of the tile holding frame 2 constituting the tile cassette 3 to be attached is fixed to the front surface of the base frame 4 by bolting.

  After that, the operation of attaching another tile cassette 3 to the upper side of the tile cassette 3 that is most recently attached to the base frame 4 is repeated, and the tile cassettes 3 may be sequentially stacked. Each attachment operation can be performed in the same manner as the case where another tile cassette 3 is attached above the lowermost tile cassette 3 described above. As shown in the upper part of FIG. 2, the tile holding frame 2 constituting the tile cassette 3 attached to the uppermost part of the base frame 4 does not need to be provided with the upward claws 13 and the upward engagement pieces 14. The upward extension 17 may have a shape that can be bolted to the uppermost part of the base frame 4.

  In the present embodiment described above, the following effects can be obtained.

  As described above, the tile 1 is attached to the building frame via the base frame 4 while being held by the tile holding frame 2, and the tile holding frame 2 and the base frame 4 are bolted together. The followability to impacts and deformations (distortions) such as earthquakes is extremely high, and the separation and fall of the tile 1 are effectively suppressed.

  In addition, the tile cassette 3 is not fixed only by bolting to the base frame 4, but is fitted to the upper and lower tile cassettes 3 (the lower groove 7 and the upper claws 13 are fitted, the upper engaging pieces 14 and Since the elastic adhesive 5 is used in combination with these mechanical fixings, the tile 1 is prevented from dropping off and the safety is significantly improved.

  In addition, even if the base frame 4 is bent, the upper and lower tile cassettes 3 are fitted to each other (the lower groove 7 and the upward claws 13 are engaged, and the upward engaging pieces 14 and the downward engaging pieces 15 are engaged). It is possible to follow the deformation by a slight change of the angle, and the fitting angle can be changed greatly if the fitting shape is appropriately deformed, for example, the upward claws 13 are trapezoidal or inclined. . That is, FIG. 1 and FIG. 2 mainly describe the case where the front surface portion of the base frame 4 is a vertical surface, but this is not limiting, and the front surface portion of the base frame 4 is an inclined surface, a horizontal surface, and an R surface. If the amount of fitting is different between the left and right sides of the tile cassette 3, a cylindrical surface, a spherical surface, or the like can be handled. Further, in each tile cassette 3, the positions where the lower grooves 7 and the upward claws 13 are provided are not fixed, but are shifted in the front-rear direction of the tile cassette 3, so that the tile cassettes are positioned relative to the front surface of the base frame 4 that is not flat. 3 may be provided in a flat manner, or conversely, a plurality of tile cassettes 3 may be provided so as to have an uneven step with respect to the front portion of the flat base frame 4. Of course, it is possible to match the positions of the lower grooves 7 and the upward claws 13 so that the upper and lower surfaces of the tile 1 do not differ.

  The tile support method of this embodiment can also be used for high-rise buildings. Conventionally, when tile finishing is performed in a high-rise building, it is common to drive into a PC. However, in this embodiment, the tile 1 is attached to the base frame 4 (aluminum curtain wall), so that it is particularly compared with the tile driving RC. As a result, a significant weight reduction of the exterior can be achieved.

  In the present embodiment, as shown in FIG. 1, in the tile cassette 3, the tile holding frame 2 covers only a part of the lower end surface of the tile 1 (the heel portion 10). 2, even if the elastic adhesive 5 is excessively applied to the tile 1, the excessive elastic adhesive 5 is smoothly discharged below the tile holding frame 2 without accumulating wastefully. It will be. Therefore, the bonding operation between the tile 1 and the tile holding frame 2 using the elastic adhesive 5 can be easily performed.

  In the present embodiment, the heel portion 10 of the tile 1 is placed on the receiving portion 11 of the tile holding frame 2, and therefore, the weight (long-term load) of the tile 1 is surface-supported by the receiving portion 11 of the tile holding frame 2. A long-term shearing force is hardly applied to the elastic adhesive 5 that bonds the tile 1 and the tile holding frame 2, so that the weight of the tile 1 can be increased.

  In this embodiment, since the entire back surface of the tile 1 is bonded to the tile holding frame 2, not only the workability can be improved by integrating the tile 1 and the tile holding frame 2, but also the tile 1. It is possible to prevent scattering when cracks occur and reinforce the rigidity of the tile 1.

  In addition, in the present embodiment, as shown in FIG. 1, the inner corner (back side) of the tile 1 is chamfered to R, so that the tile 1 can be easily fitted into the tile holding frame 2 and an elastic adhesive is used. 5 can be prevented, and the local concentrated load at the time of deformation is changed so as to be adapted to the uneven distribution load on the surface by the R-type chamfering.

  In this embodiment, when the tile cassette 3 is attached to the base frame 4, as shown in FIG. 1, the upward extension 17 of the tile holding frame 2 is joined to the base frame 4 with the bolt 18, and the bolt 18 The front side is covered with the main body 9 of the tile holding frame 2 in another tile cassette 3 stacked on the upper side of the tile cassette 3 to which the bolt 18 is to be joined. In addition, when the bolt 18 is fastened to the upward extension 17, the extra length of the bolt 18 is set to be longer than the clearance between the bolt 18 and the main body 9 covering the front side thereof. Even if 18 is loose, it can be reliably prevented from falling off.

  In this embodiment, as shown in FIG. 1, a bolt 18 is attached to an upper portion of a planar upward extension 17 of the tile holding frame 2, and a downward engagement piece 15 is connected to an upper end of the upward extension 17. An upward engagement piece 14 used for engagement is provided continuously. That is, since the upward engaging piece 14 that exhibits the rib effect is provided in the vicinity of the mounting position of the bolt 18 in the tile holding frame 2, the strength burden on the upward extending portion 17 is reduced, and an economical sectional design is possible. It has become.

  In this embodiment, when the tile cassette 3 is attached to the base frame 4, as shown in FIGS. 3A and 3B, the two sides of the upward extension 17 of the tile holding frame 2 are grounded with bolts 18. It is made to join to the frame 4. If one of the holes through which the bolt 18 passes in the upward extending portion 17 is a loose hole that is long in the left-right direction, the accuracy error is absorbed, and even if it receives various loads (repetitive vibrations, temporary impacts, etc.), the position shifts. Is less likely to occur and is easy to follow the deformation. Of course, a plurality of washers having different thicknesses may be prepared, and a washer having an arbitrary thickness may be set on the bolt 18 for fine adjustment to absorb accuracy errors.

  Further, in the present embodiment, in the two tile cassettes 3 that are vertically connected, the groove 7 formed on the lower end surface of the tile 1 of the upper tile cassette 3 is the upward facing of the tile holding frame 2 of the lower tile cassette 3. The tile cassettes 3 are sequentially stacked from below and attached to the base frame 4. Therefore, each tile cassette 3 has an angle in a bellows-like manner, and if one of the holes through which the bolt 18 passes in the upward extending portion 17 is a loose hole, the tile is combined with the elasticity of the base frame 4 and the tile. Interlayer displacement between the cassettes 3 can be absorbed gently (absorption up to 1/100 has been confirmed by a full-scale test), and it is extremely resistant to bending and warping during wind resistance. When the tile holding frame 2 is connected to the base frame 4 directly attached to a highly rigid housing or the like, interlayer displacement absorption at the joint between the tile cassettes 3 can be expected.

  In addition, this invention is not limited to said embodiment at all, Of course, it can change and implement variously in the range which does not deviate from the summary of this invention. For example, the following modifications can be given.

  In the above-described embodiment, the tile 1 and the tile holding frame 2 are separated from each other. However, the present invention is not limited to this. For example, the tile holding frame 2 is embedded in the tile 1 and both 1 and 2 are baked integrally. Good.

  In the above-described embodiment, one tile holding frame 2 holds one tile 1. However, the present invention is not limited to this. For example, one tile holding frame 2 holds a plurality of tiles 1. Alternatively, one tile 1 may be held by a plurality of tile holding frames 2.

  In addition, as shown in FIG. 4, a plurality of tile cassettes 3 may be attached to one base frame 4 in a vertical row, but the present invention is not limited to this. For example, for one base frame 4 The tile cassettes 3 may be attached in two or more rows, or the tile cassettes 3 may be attached to the base frame 4 in a staggered manner.

  In the above embodiment, the tile holding frame 2 is an aluminum extruded shape. However, the present invention is not limited to this. For example, the tile holding frame 2 may be formed of other metals such as steel and stainless steel, resin, rubber, or the like. Good.

  A joint material may be provided in the gap between the tile cassettes 3 attached to the base frame 4 so as to be lined up and down, or a part of the tile holding frame 2 (upward claws 13,. It is good also as a specification which the downward nail | claw 8) can be seen outside.

  In the example shown in FIGS. 3A and 3B, the upper and lower grooves 6 and 7 of the tile 1 are not passed to the left and right ends of the tile 1, but the upper and lower grooves 6 and 7 are not limited to this. 1 may be evenly passed to the left and right ends, or the edge of the tile 1 may be processed to be different from the cross section of the center of the tile 1 provided with the upper and lower grooves 6 and 7.

  When stacking the tile cassette 3 by fitting the upward claw 13 of the tile cassette 3 attached to the base frame 4 into the lower groove 7 of the tile cassette 3 to be attached, the inside of the lower groove 7 The elastic adhesive 5 may be applied to the surface, or may be simply fitted without being applied.

  Here, when the elastic adhesive 5 is applied in the lower groove 7, the tile cassette 3 can be replaced as shown in FIG. That is, FIG. 5 shows a case where the third tile cassette 3 from the top is the replacement target. However, this is not a limitation, and unless the tile cassette 3 to be replaced is the top tile cassette 3, It is necessary to sequentially remove the uppermost tile cassette 3 to the tile cassette 3 to be replaced from the base frame 4. Each tile cassette 3 is removed by loosening and removing the bolt 18 that fixes the tile cassette 3 to the base frame 4 and is fitted in the groove 7 on the lower side of the tile cassette 3. 3 can be removed from the base frame 4 by cutting the upward claw 13 at the base.

  After removing from the base frame 4 the tile cassette 3 to be replaced from the uppermost tile cassette 3 in this way, the tile cassette 3 immediately below the tile cassette 3 to be replaced (the fourth tile cassette from the top). 3) The upward claws 13 of the tile holding frame 2 are also cut at the roots. Therefore, a bent plate-like attachment 20 provided with an upward claw 13 is provided from the upper surface of the bridge portion 12 of the tile holding frame 2 of the tile cassette 3 directly below the tile cassette 3 to the front surface of the upward extension portion 17. Attach to frame 4. This attachment can be performed using a connecting member 21 such as a tapping screw, for example, as shown in FIGS. And after attaching the attachment 20, what is necessary is just to attach to the base frame 4, laminating | stacking the tile cassette 3 on the upper direction sequentially.

  In the embodiment described above, the portion of the tile holding frame 2 that is joined to the base frame 4 by the bolt 18 is the upward extension 17 that extends upward from the main body 9, and the tile cassette 3 that is attached to the base frame 4 is located from the bottom to the top. However, the present invention is not limited to this. For example, the tile holding frame 2 is provided with a portion that extends downward from the main body 9, and this portion is joined to the base frame 4 with the bolts 18. The tile cassette 3 attached to the frame 4 may be stacked from the top to the bottom. In this case, the positions where the upward engagement pieces 14 and the downward engagement pieces 15 are provided in the tile holding frame 2 may be changed as appropriate, and the engagement pieces 14 and 15 may not be provided.

  Needless to say, the modifications described in this specification may be combined as appropriate.
