Description

[Technical Field]

[0001] The present invention relates to tiled overhang corners. [Background technology]

[0002] When constructing the exterior walls of buildings, tiles are sometimes applied to the exterior wall's base material (base concrete) using a wet construction method, with an adhesive layer made of mortar or organic adhesive interposed between them. Tiled exterior walls are used as exterior walls that give buildings a wide range of design options and high durability. When tiling is performed using an adhesive layer made of organic adhesive, the adhesive layer can absorb the differential movement (relative strain) that occurs between the tile and the base material, preventing tile peeling and falling off. This results in tiled exterior walls that are even more durable and have excellent seismic safety, and as such have become increasingly popular in recent years.

[0003] In the general areas of tiled exterior walls, multiple flat tiles are arranged on the surface of the base material, above, below, left and right, via vertical and horizontal joints, and at the protruding corners of the tiled exterior wall, multiple accessory tiles that are L-shaped in plan view are arranged above and below, via horizontal joints, and flat tiles are arranged on the left and right sides of each accessory tile via vertical joints.

[0004] As an example of a wet tiling method, Patent Document 1 proposes a wet tiling method (herein referred to as a wet tiling method) that enables tiling of the protruding corners of a building's exterior wall at low cost while ensuring the required quality. Specifically, the method includes the steps of assembling a formwork for the building's exterior wall and placing a chamfered spacer having a right-angled isosceles triangular cross section at the protruding corner inside the formwork, with the hypotenuse of the chamfered spacer selected to be substantially equal to the width of the tile to be applied to the protruding corner. The wet tiling method further includes the steps of pouring concrete into the formwork, removing the formwork after the concrete has hardened, applying adhesive mortar to the concrete wall, applying tile on the adhesive mortar, applying joint mortar to the tile surface so that it fills the joints, and wiping off any excess joint mortar remaining on the tile surface.

[0005] [Patent Document 1] Japanese Patent Application Publication No. 11-152876 Summary of the Invention [Problem to be solved by the invention]

[0006] For example, when tiles are attached to the surface of a base material via an adhesive layer made of an organic adhesive as described above, the inventors have identified that cracks may occur in accessory tiles installed at protruding corners, even if the adhesive fill rate, coating thickness, and adhesive strength are all good. This will be explained with reference to Figures 1 and 2.

[0007] FIG. 1 is a diagram illustrating a conventional tiled protruding corner, showing a horizontal cross-section taken at an arbitrary level of the protruding corner of a building, and FIG. 2 is a view taken in the direction of arrow II in FIG. 1, showing a portion of the protruding corner of a building as seen from the outdoor side. In the example shown in FIGS. 1 and 2, the wall width of side surface 11 in the Y direction is larger than the wall width of side surface 12 in the X direction, of the two width directions of side surfaces 11 and 12 that are perpendicular to each other, that is, the Y direction and the X direction, and the amount of deformation due to temperature change when side surface 11 deforms in the X direction is relatively large. In FIG. 1, side surfaces 11 and 12 before temperature deformation are shown by solid lines, and side surfaces 11 and 12 after temperature change (here, after temperature decrease) are shown by dashed dotted lines.

[0008] At a projected corner D1 where two side surfaces 11, 12 of a concrete (reinforced concrete) base material 10 intersect, accessory tiles 20 and flat tiles 30 are attached to the surface (side surfaces 11, 12) of the base material 10 via an adhesive layer 40, thereby forming a tiled projected corner 80. At the corner portion of the projected corner D1, multiple accessory tiles 20 that are L-shaped in plan view are attached vertically via horizontal joints 52, and multiple flat tiles 30 are attached to the left and right sides of the two halves 21 of the accessory tiles 20 via vertical joints 51. Conventionally, the vertical joints 51 are mortar joints 51A in which mortar, a cement-based material, is applied to the joint, and the horizontal joints 52 are also mortar joints.

[0009] Tiles are generally made by sintering stone, earth, clay, etc. at temperatures above 1000°C, but their linear expansion coefficient is smaller than that of concrete. Therefore, when temperatures change, such as the outside air temperature, there is a difference in the amount of deformation between the base material 10 and the accessory tiles 20 and flat tiles 30. For example, when the temperature drops as shown in the figure, a difference in deformation Δδ1 (shrinkage difference) in the X direction may occur between the base material 10 and the accessory tiles 20. Each of the two pieces 21 of the accessory tile 20 is adhered to the base material 10 via an adhesive layer 40 and is further adhered to the adjacent flat tiles 30 via mortar joints 51A.

[0010] Therefore, a tensile force (or restraining force) P1 in the X direction due to the difference in deformation Δδ1 between the side surface 11 to which the back surface of the accessory tile 20 is adhered acts on the one side 21A of the accessory tile 20. This tensile force P1 may cause bending M1 in the one side 21A of the accessory tile 20.

[0011] On the other hand, due to the difference in deformation Δδ1 with the base material 10, a thrust force (or reaction force) P2 acts on the other piece 21B of the accessory tile 20 from the lateral flat tile 30 through the mortar joint 51A, and this thrust force P2 and tensile force P1 can also generate a shear force S1 on one piece 21A of the accessory tile 20.

[0012] The inventors have determined that these bending forces M1 and shear forces S1 cause vertical cracks C, as shown in Figures 1 and 2, to occur in one piece 21A of the accessory tile 20. If the relative magnitude relationship of the deformation amounts due to temperature changes on the two side surfaces 11, 12 is reversed, the direction of the resulting bending and shear forces will change, potentially causing cracks to occur in the other piece 21B instead of the one piece 21A. Including the wet tiling method described in Patent Document 1, no technology has existed to date that can suppress or prevent cracks C that can occur in the accessory tile 20 due to differences in deformation between the base material 10, as shown in Figures 1 and 2.

[0013] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a tiled protruding corner that can suppress or prevent cracks that may occur in accessory tiles at the corners of buildings due to differences in deformation between the accessory tiles and the base material, which have different linear expansion coefficients. [Means for solving the problem]

[0014] In order to achieve the above object, one aspect of the tiled corner according to the present invention is as follows: A tiled protruding corner where two side surfaces that make up a building intersect, and a first accessory tile that is L-shaped in plan view and a flat tile are attached to the surface of the base material of the protruding corner via an adhesive layer, The first accessory tile is attached to the corner of the protruding corner, and the flat tiles are attached to the left and right sides of the first accessory tile via vertical joints, A cushioning material is provided in at least one of the left and right vertical joints.

[0015] According to this aspect, at the corner where the two side faces intersect, a cushioning material is placed in at least one of the two lateral vertical joints of the first feature tile, which is L-shaped in plan view. This causes a difference in deformation between the first feature tile and the base material due to temperature changes, and when this difference in deformation causes a butting force to act from the lateral flat tile, the cushioning material placed in at least one of the lateral vertical joints absorbs the butting force, thereby eliminating the bending and shearing force caused by this butting force. This reduces the bending and shearing force generated in the first feature tile, making it possible to suppress or prevent the occurrence of cracks.

[0016] Here, "a cushioning material is placed in at least one of the left and right vertical joints" refers to both a configuration in which a cushioning material is placed in one of the two vertical joints on each side of the two pieces of the first accessory tile, and a configuration in which a cushioning material is placed in both vertical joints. Furthermore, in this specification, joints where mortar is applied or joints formed by the mortar swelling up when the tile is pressed against the mortar forming the adhesive layer are referred to as "mortar joints," meaning joints made of cement-based materials. Meanwhile, joints where a cushioning material is placed are referred to as "flexible joints" (joints with deformation capabilities).

[0017] Furthermore, the adhesive layer may be made of a cement-based material (e.g., mortar) or an organic adhesive, but as mentioned above, an adhesive layer made of an organic adhesive is preferred from the standpoint of preventing the tiles from peeling or falling off.

[0018] Another aspect of the tiled corner according to the present invention is: The cushioning material is disposed in one of the left and right vertical joints, and the other is a mortar joint.

[0019] According to this embodiment, cushioning material is placed in one of the two vertical joints on each side of the two pieces of the first functional tile, and the other is a mortar joint, so that a tiled protruding corner can be formed while minimizing the amount of cushioning material used.

[0020] Another aspect of the tiled corner according to the present invention is: The cushioning material is disposed in both the left and right vertical joints.

[0021] According to this aspect, cushioning material is arranged in both of the two vertical joints on each side of the two pieces of the first accessory tile, so that even if a thrust force is applied from a flat tile on either side of either piece, the bending and shear forces generated in the first accessory tile can be suppressed, thereby effectively suppressing or preventing the occurrence of cracks in the first accessory tile.

[0022] In another aspect of the tiled corner according to the present invention, One of the two pieces forming the L-shape is relatively long and the other piece is relatively short.

[0023] According to this embodiment, by using a plurality of first accessory tiles that are L-shaped in plan view and have two sides of different lengths, and for example arranging each first accessory tile above and below the protruding corner so that the long and short sides of each tile alternate, it is possible to form a tiled protruding corner that creates a varied and stylish appearance.

[0024] In another aspect of the tiled corner according to the present invention, The two pieces forming the L-shape have the same length.

[0025] According to this embodiment, by using multiple first accessory tiles that are L-shaped in plan view and have two sides of the same length, and arranging them above and below the protruding corner, it is possible to create a tiled protruding corner that creates a unified external design.

[0026] In another aspect of the tiled corner according to the present invention, A tiled protruding corner in which a second accessory tile with three intersecting pieces and a flat tile or a first accessory tile with an L-shape in plan view are attached to the surface of the base material of a protruding corner where three side surfaces constituting a building intersect, via an adhesive layer. The second accessory tile is attached to the corner of the protruding corner, and the flat tile or the first accessory tile is attached to the side of the three pieces of the second accessory tile via vertical joints and horizontal joints, The present invention is characterized in that cushioning materials are provided in all of the vertical joints and horizontal joints on the sides of the second accessory tile.

[0027] According to this aspect, at the corner where three side faces intersect, cushioning material is provided in all vertical and horizontal joints on the side of the second feature tile where the three pieces intersect. Therefore, even if a butting force is applied from a flat tile on any side (in the mutually perpendicular X, Y, or Z directions) due to differential deformation between the second feature tile and the base material during temperature changes, the cushioning material absorbs the butting force, thereby eliminating the bending and shear forces caused by the butting force. This reduces the bending and shear forces generated in the second feature tile, thereby suppressing or preventing cracking. Here, of the three pieces that make up the second feature tile, two correspond to the side (vertical surface) of the wall, and the other corresponds to the ceiling surface of the wall. Furthermore, because the vertical and horizontal joints on this ceiling surface change depending on the viewing direction, when one joint is considered a vertical joint, the joint perpendicular to it is considered a horizontal joint.

[0028] In another aspect of the tiled corner according to the present invention, The cushioning material is characterized by being a resin-based material or a resin-based foam material having deformability.

[0029] According to this aspect, since the cushioning material is a resin-based material or a resin-based foam material with deformability, the first accessory tile can effectively absorb the thrust force acting from the flat tile on its side, and the second accessory tile can effectively absorb the thrust force acting from the first accessory tile or flat tile on its side.

[0030] In another aspect of the tiled corner according to the present invention, The cushioning material has a width equal to the entire width of the vertical joint or horizontal joint to be disposed.

[0031] According to this aspect, since the cushioning material has the full width of the vertical or horizontal joint to be installed, flexible joints can be quickly constructed by temporarily fixing the cushioning material to the side of the first or second accessory tile and then attaching flat tiles or the like to the side of those tiles, thereby improving workability.

[0032] In another aspect of the tiled corner according to the present invention, The buffer material has a width narrower than the width of the vertical joint or horizontal joint to be disposed, and mortar is applied to an area including the remaining width.

[0033] According to this aspect, the cushioning material has a width narrower than the width of the vertical or horizontal joint to be installed, and mortar is applied to the area including the remaining width, so that flexible joints can be constructed while minimizing the amount of cushioning material used as much as possible. [Effects of the Invention]

[0034] As can be understood from the above explanation, the tiled protruding corner of the present invention can suppress or prevent cracks that may occur in accessory tiles at the corners of buildings due to differences in deformation between the accessory tiles and the base material, which have different linear expansion coefficients.

[Figure 7] FIG. 10 is a perspective view of a portion of a tiled protruding corner according to a fifth embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0036] Hereinafter, examples of tiled protruding corners according to each embodiment will be described with reference to the accompanying drawings. Note that in this specification and drawings, substantially identical components may be designated by the same reference numerals to avoid redundant description.

[0037] [Tiled corner according to the first embodiment] First, an example of a tiled protruding corner according to the first embodiment will be described with reference to Fig. 3. Here, Fig. 3 is a perspective view of a part of the tiled protruding corner according to the first embodiment.

[0038] The tiled protruding corner 90A is formed by attaching a plurality of first accessory tiles 20 that are L-shaped in plan view and a plurality of flat tiles 30 via an adhesive layer 40 to the surface (sides 11, 12) of the base material 10 (base concrete) of the protruding corner D1 where the two side surfaces 11, 12 that make up the building intersect.

[0039] At the corner of the projected corner D1, a plurality of first accessory tiles 20 are arranged vertically via horizontal joints 52, and flat tiles 30 are arranged on the left and right sides of each first accessory tile 20 via vertical joints 51.

[0040] The first accessory tile 20 in the illustrated example has two L-shaped pieces 21 of the same length, but one of the two pieces may be relatively long and the other relatively short.

[0041] The adhesive layer 40 is formed from an organic adhesive, and examples of such organic adhesives include modified silicone resin adhesives, modified silicone-epoxy resin adhesives, etc. The adhesive layer 40 may be formed from mortar, but as mentioned above, it is preferable to form it from an organic adhesive in order to prevent the tiles from peeling or falling off.

[0042] The horizontal joints 52 are mortar joints. The mortar joints are formed by adhering each first feature tile 20 and each flat tile 30 to the adhesive layer 40, and then applying mortar to the horizontal joints.

[0043] On the other hand, with regard to the vertical joints 51, the vertical joints 51 between the flat tiles 30 are mortar joints 51A. In contrast, of the two vertical joints 51 between the first feature tile 20 and the left and right flat tiles 30, one vertical joint 51 is a mortar joint 51A, and the other vertical joint 51 is a flexible joint 51B with deformation capability, in which a buffer material having the full width of the joint is arranged.

[0044] The buffer material can be made of silicone, modified silicone, polysulfide, acrylic urethane, polyisobutyl, polyurethane, acrylic, butyl rubber, or other resins, including EPDM (ethylene propylene diene rubber), which is an example of synthetic rubber. Other examples include polyvinyl chloride resin, EVA resin (ethylene-vinyl acetate copolymer resin), polyethylene resin, and foams made from rubber.

[0045] Because the vertical joint 51 on one side of the first accessory tile 20 is a flexible joint 51B made of a cushioning material that has the full width of the joint, as shown in Figure 3, there is a difference in deformation between the first accessory tile 20 and the base material 10 when the temperature changes, and when a thrust force P2 is applied from the flat tile 30 on the side due to this difference in deformation, the cushioning material that forms the flexible joint 51B absorbs the thrust force P2, thereby eliminating the bending and shear forces caused by this thrust force P2 and suppressing the bending and shear forces that occur in the first accessory tile 20. This makes it possible to suppress or prevent the occurrence of cracks that may occur in the first accessory tile 20 (crack C shown in Figures 1 and 2).

[0046] [Tiled corner according to the second embodiment] Next, an example of a tiled protruding corner according to the second embodiment will be described with reference to Fig. 4. Here, Fig. 4 is a perspective view of a part of the tiled protruding corner according to the second embodiment.

[0047] The tiled protruding corner 90B differs from the tiled protruding corner 90A shown in Figure 3 in that the vertical joint 51 on one side of the first accessory tile 20 has a flexible joint 51C with a cushioning material 51B' that is narrower than the overall width of the vertical joint.

[0048] For example, a cushioning material 51B' having a width of about 10% to 50% of the total width of the vertical joint is attached in advance to the end face of one side 21 of the first accessory tile 20, and after the first accessory tile 20 and the flat tile 30 on its side are adhered to the adhesive layer 40, mortar is applied to the remaining width area of ​​the vertical joint 51, thereby embedding mortar 51A' on the side of the cushioning material 51B', and a flexible joint 51C formed by the cushioning material 51B' and mortar 51A' is formed.

[0049] Also because the vertical joint 51 on one side of the first feature tile 20 is a flexible joint 51C formed by cushioning material 51B' and mortar 51A', when a thrust force P2 acts from the lateral flat tile 30 due to the difference in deformation between the first feature tile 20 and the base material 10, as shown in Figure 4, the cushioning material 51B' forming the flexible joint 51C can absorb the thrust force P2, making it possible to suppress or prevent the occurrence of cracks that may occur in the first feature tile 20.

[0050] [Tile-protruding corner according to the third embodiment] Next, an example of a tiled protruding corner according to the third embodiment will be described with reference to Fig. 5. Here, Fig. 5 is a perspective view of a part of the tiled protruding corner according to the third embodiment.

[0051] The tiled protruding corner 90C differs from the tiled protruding corners 90A and 90B shown in Figures 1 and 2 in that the vertical joints 51 on both the left and right sides of the first accessory tile 20 have flexible joints 51B equipped with cushioning material spanning the entire width of the vertical joints.

[0052] With the tile protruding corner 90C, as shown in Figure 5, even if a thrust force P2 acts on either of the flexible joints 51B on the sides of the two pieces 21, the cushioning material forming the flexible joint 51B can absorb the thrust force P2, making it possible to suppress or prevent the occurrence of cracks that may occur in the first accessory tile 20.

[0053] Although not shown in the figures, both of the left and right flexible joints 51B of the first accessory tile 20 may be the flexible joints 51C shown in Figure 4, or either one of the left and right flexible joints 51B may be the flexible joint 51C.

[0054] Here, the effects specific to each of the tiled protruding corners 90A, 90B, and 90C shown in FIGS. 3 to 5 are as follows.

[0055] First, in the tiled protruding corner 90A shown in Figure 3, one of the vertical joints 51 is a flexible joint 51B, which reduces the material costs required for the cushioning material compared to when cushioning material is provided in both the left and right vertical joints 51. Furthermore, by attaching cushioning material 51B having the full width of the vertical joint to the end face of one side 21 in advance, after the first accessory tile 20 is installed on the adhesive layer 40, the flexible joint 51B is automatically installed when the side flat tile 30 is installed, improving workability.

[0056] On the other hand, with the tiled protruding corner 90B shown in Figure 4, the amount of cushioning material 51B' used is smaller than that of the cushioning material 51B of the tiled protruding corner 90A, making it possible to further reduce the material costs required for the cushioning material.

[0057] On the other hand, according to the tile protruding corner 90C shown in Figure 5, the left and right vertical joints 51 of the first accessory tile 20 are flexible joints 51B, so regardless of whether a thrust force P2 acts from the left or right direction, the thrust force P2 can be absorbed by the cushioning material 51B, thereby further enhancing the effect of suppressing the occurrence of cracks that may occur in the first accessory tile 20.

[0058] Incidentally, the combinations of vertical joints on the left and right sides of the first accessory tile 20, including each tile protruding corner according to the first to third embodiments described above, include (1) a flexible joint 51B (only buffer material) on one side and a mortar joint 51A on the other, (2) a flexible joint 51C (buffer material 51B' and mortar 51A') on one side and a mortar joint 51A on the other, (3) a flexible joint 51B on both sides, and (4) a flexible joint 51C on both sides. Furthermore, other combinations are also possible, such as (5) a flexible joint 51B on one side and a sealing joint on the other, (6) a flexible joint 51C on one side and a sealing joint on the other, and (7) a sealing joint on both sides.

[0059] [Tiled corner according to the fourth embodiment] Next, an example of a tiled protruding corner according to the fourth embodiment will be described with reference to Fig. 6. Here, Fig. 6 is a perspective view of a part of the tiled protruding corner according to the fourth embodiment.

[0060] Unlike the tiled projecting corners 90A to 90C already described with reference to Figures 3 to 5, the tiled projecting corner 90D shown in Figure 6 is formed by attaching a second accessory tile 70 having three intersecting pieces 71, a plurality of first accessory tiles 20 that are L-shaped in plan view, and a plurality of flat tiles 30 via an adhesive layer (not shown) to the surface of the base material (not shown) of the projecting corner D2 where the three side surfaces that make up the building intersect.

[0061] A second accessory tile 70 is arranged at the corner of the protruding corner D2, and a first accessory tile 20 is arranged on the left and right sides and below the second accessory tile 70 via joints.

[0062] Flexible joints 51B, in which cushioning material is arranged over the entire width of the vertical joint, are formed on the left and right sides of the two vertical pieces 71A of the second accessory tile 70. In addition, cushioning material 51B is also arranged in the horizontal joints below the two vertical pieces 71A, forming flexible joints 51B.

[0063] On the other hand, flexible joints 51B are also formed in the joints (one is a vertical joint and the other is a horizontal joint) between the horizontal piece 71B on the ceiling of the second accessory tile 70 at the projected corner D2 and the first accessory tiles 20 on either side of it, in which cushioning material having the full width of the joint is arranged.

[0064] In addition, the vertical joints 51 and horizontal joints 52 between the other first accessory tiles 20 and the first accessory tiles 20, and the joints between the first accessory tiles 20 and the flat tiles 30 are all mortar joints.

[0065] In this way, since the joints around the entire circumference of the second accessory tile 70 located at the corner of the protruding corner D2 where the three side surfaces intersect are flexible joints 51B, as shown in Figure 6, even if a thrust force P2 acts from any of the three directions, left and right, lateral and downward, the thrust force P2 can be absorbed by the cushioning material 51B, thereby suppressing or preventing the occurrence of cracks that may occur in the second accessory tile 70.

[0066] [Tiled corner according to the fifth embodiment] Next, an example of a tiled protruding corner according to the fifth embodiment will be described with reference to Fig. 7. Here, Fig. 7 is a perspective view of a part of the tiled protruding corner according to the fifth embodiment.

[0067] The tiled protruding corner 90E differs from the tiled protruding corner 90D shown in Figure 6 in that the side joints around the entire periphery of the second accessory tile 70 have flexible joints 51C equipped with cushioning material 51B' and mortar 51A' that are narrower than the overall width of the joint.

[0068] In this way, because the joints around the entire periphery of second accessory tile 70 at the corner of projected corner D2 where three side surfaces intersect are flexible joints 51C, even if a thrust force P2 acts from any of the three directions (left, right, lateral, and downward), the thrust force P2 can be absorbed by cushioning material 51C, as shown in Figure 7. Furthermore, because less cushioning material 51B' is used than cushioning material 51B at tiled projected corner 90D, it is possible to reduce the material cost required for the cushioning material.

[0069] The present invention is not limited to the configurations shown here, and other embodiments may be possible in which other components are combined with the configurations described in the above embodiments. In this regard, the present invention can be modified within the scope of the present invention, and can be appropriately determined depending on the application form. [Explanation of symbols]
