Description

[Technical field]

[0001] The present invention relates to a tiled corner. [Background technology]

[0002] In the construction of the exterior walls of buildings, tiles are sometimes applied to the base material (base concrete) of the exterior wall by a wet construction method using an adhesive layer made of mortar or organic adhesive. Tiled exterior walls are used as exterior walls that give buildings a variety of designs 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, so it is expected that the tiles will not peel or fall off, and this results in a tiled exterior wall that has further improved durability and excellent seismic safety, and has become increasingly popular in recent years.

[0003] In general areas of tiled exterior walls, multiple flat tiles are arranged above, below, left and right on the surface of the base material via vertical and horizontal joints, and at the 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] Here, as an example of a wet tiling method, Patent Document 1 proposes a wet tiling method (here, wet tiling method) that can perform tiling at the protruding corners of the exterior walls of buildings at low cost while ensuring the required quality. Specifically, the method includes a step of assembling a form for the exterior walls of the building, and a step of placing a chamfered spacer having a cross section of a right-angled isosceles triangle at the protruding corner inside the form, and the hypotenuse of the chamfered spacer is selected so as to be substantially equal to the width of the tile to be applied to the protruding corner. The wet tiling method further includes a step of pouring concrete into the form, a step of removing the form after the concrete has hardened, a step of applying adhesive mortar to the concrete wall, a step of applying joint mortar to the tile surface so as to fill the joints, and a step of wiping off 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 the accessory tiles installed at the protruding corners even if the adhesive filling 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 for explaining a conventional tiled protruding corner, and is a horizontal cross-sectional view of a protruding corner of a building at an arbitrary level, and Fig. 2 is a view in the direction of the arrow II in Fig. 1, showing a part of the protruding corner of a building seen from the outdoor side. In the example shown in Fig. 1 and Fig. 2, the wall width of the side surface 11 in the Y direction is larger than the wall width of the side surface 12 in the X direction, for example, of the width directions of the side surfaces 11 and 12 in two mutually perpendicular directions, the Y direction and the X direction, and the deformation amount due to temperature change is relatively large when the side surface 11 deforms in the X direction. In Fig. 1, the side surfaces 11 and 12 before temperature deformation are shown by solid lines, and the side surfaces 11 and 12 after temperature change (here, after temperature drop) are shown by dashed and dotted lines.

[0008] At a projected corner D1 where two side surfaces 11, 12 of a base material 10 made of concrete (made of reinforced concrete) 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, a plurality of accessory tiles 20 that are L-shaped in plan view are attached in the vertical direction via horizontal joints 52, and a plurality of flat tiles 30 are attached to the left and right sides of the two pieces 21 of the accessory tile 20 via vertical joints 51. As a conventional general joint, the vertical joint 51 is a mortar joint 51A in which mortar, a cement-based material, is applied to the joint, and the horizontal joint 52 is also a mortar joint.

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

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

[0011] On the other hand, due to the deformation difference 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 side 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 M1 and shearing 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 of the two side surfaces 11, 12 is reversed, the direction of the generated bending and shearing forces will change, and cracks may occur in the other piece 21B instead of the one piece 21A. Furthermore, there has been no technology to date that suppresses or prevents cracks C that may occur in the accessory tile 20 due to the difference in deformation between the base material 10 as shown in Figures 1 and 2, including the wet tiling method described in Patent Document 1.

[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 present invention is a tiled corner that: A tiled protruding corner where two sides of a building intersect, with a first feature tile in an L-shape in plan view and a flat tile affixed to the surface of the base material of the protruding corner, Of the two surfaces of the base material at the corner portion of the protruding corner, one piece of the first accessory tile is attached to one of the surfaces via an adhesive layer, and the other piece of the first accessory tile is not attached to the other surface; The flat tiles are arranged on the left and right sides of the first feature tile via vertical joints, and the flat tiles are attached to the surface of the base material via an adhesive layer.

[0015] According to this embodiment, at the corner where the two sides intersect, one side of the first accessory tile, which is L-shaped in plan view, is attached to one surface of the base material via an adhesive layer, and the other side is not attached to the other surface of the base material. Even if there is a deformation difference between the first accessory tile and the base material due to temperature changes, this deformation difference prevents the base material from exerting a tensile force on the other side, thereby eliminating bending and shear forces caused by this tensile force. This makes it possible to suppress bending and shear forces generated in the first accessory tile, and to suppress or prevent the occurrence of cracks.

[0016] The adhesive layer that bonds one surface of the base material and one piece of the first component tile 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 tile from peeling or falling off.

[0017] In another aspect of the tiled corner according to the present invention, Of the left and right vertical joints, the vertical joint on the side of one piece is a mortar joint, and the vertical joint on the side of the other piece is an open joint or a sealing joint with deformation ability.

[0018] According to this embodiment, the vertical joint on the side of the other piece of the first feature tile that is not attached to the surface of the base material is an open joint or a sealing joint with deformation performance, so that the other piece is not restricted to the flat tile on the side, for example, through a mortar joint. In other words, in addition to the tensile force that the other piece of the first feature tile receives from the base material as described above being eliminated, the restrictive force from the flat tile on the side of the other piece is also eliminated through the mortar joint, so that it is possible to further suppress the occurrence of cracks in the other piece.

[0019] In this specification, the term "mortar joint" refers to a joint that is applied with mortar or a joint that is formed by the rise of mortar when a tile is pressed against the mortar that forms the adhesive layer, and means a joint made of cement-based materials. On the other hand, a sealing joint with deformation performance refers to a joint that has waterproofing and airtightness, which is formed by filling the joint with an indefinite elastic sealant or elastic sealant, or by fitting a fixed elastic sealant into the joint. Furthermore, an open joint is, as the name suggests, a joint that is formed by a gap without mortar or elastic sealant.

[0020] In another aspect of the tiled corner according to the present invention, The vertical joints on each side of the two pieces of the first feature tile are mortar joints.

[0021] According to this aspect, the vertical joints on each side of the two pieces of the first feature tile are mortar joints, which allows for construction in the same way as other vertical joints, resulting in good workability.

[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 multiple first accessory tiles that are L-shaped in plan view and have two pieces of different lengths, and, for example, arranging each first accessory tile above and below the protruding corner so that the long and short pieces alternate, it is possible to form a tiled protruding corner that creates a varied external design.

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

[0025] According to this embodiment, by using multiple first accessory tiles that are L-shaped in plan view, with two sides 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 mutually intersecting pieces and a flat tile or a first accessory tile that is L-shaped in plan view are affixed to the surface of the base material of a protruding corner where three side surfaces constituting a building intersect, One of the three surfaces of the base material at the corner portion of the protruding corner is attached to one piece of the second feature tile via an adhesive layer, and the other two surfaces of the base material are not attached to the other two pieces of the second feature tile, the flat tile or the first feature tile is arranged on the sides of the three pieces of the second feature tile via vertical joints and horizontal joints, the flat tile or the first feature tile is attached to the surface of the base material via an adhesive layer, and all of the vertical joints and horizontal joints on the sides of the second feature tile are mortar joints.

[0027] According to this embodiment, at a corner where three side surfaces intersect, one piece of the second accessory tile where the three pieces intersect with each other is attached to one surface of the base material via an adhesive layer, and the other two pieces of the second accessory tile are not attached to the other two surfaces of the base material. Even if there is a deformation difference between the second accessory tile and the base material when the temperature changes, this deformation difference prevents the base material from exerting a tensile force on the two pieces (the pieces not attached to the base material), and the bending and shearing forces caused by this tensile force can be eliminated. This makes it possible to suppress the bending and shearing forces generated in the second accessory tile, and to suppress or prevent the occurrence of cracks. Here, of the three pieces constituting the second accessory tile, two pieces correspond to the side surfaces (vertical surfaces) of the wall, and the other piece corresponds to the ceiling surface of the wall. And, on this ceiling surface, the vertical joints and horizontal joints change depending on the viewing direction, so when one joint is a vertical joint, the joint perpendicular to it is a horizontal joint. In this embodiment, the joints around the entire periphery of the second feature tile are mortar joints.

[0028] In another aspect of the tiled corner according to the present invention, A tiled protruding corner in which a second accessory tile with three mutually intersecting pieces and a flat tile or a first accessory tile that is L-shaped in plan view are affixed to the surface of the base material of a protruding corner where three side surfaces constituting a building intersect, Two of the three faces of the base material at the corner portion of the protruding corner are attached to the two pieces of the second feature tile via an adhesive layer, and the other face of the base material is not attached to the other piece of the second feature tile, the flat tile or the first feature tile is arranged on the sides of the three pieces of the second feature tile via vertical joints and horizontal joints, the flat tile or the first feature tile is attached to the surface of the base material via an adhesive layer, and of the vertical joints and horizontal joints on the sides of the second feature tile, at least the vertical joints and horizontal joints corresponding to the other piece are open joints or sealing joints with deformable properties.

[0029] According to this embodiment, at a corner where three side surfaces intersect, two pieces of the second accessory tile, whose three pieces intersect with each other, are attached to two sides of the base material via an adhesive layer, and the other piece of the second accessory tile is not attached to the other side of the base material, and the joint (vertical joint or horizontal joint) corresponding to the other piece is an open joint or a sealing joint with deformable ability.This prevents tensile force from acting on one piece (the piece not attached to the base material) from the base material due to deformation differences between the second accessory tile and the base material when the temperature changes, and therefore eliminates bending and shear forces caused by this tensile force, making it possible to suppress or prevent the occurrence of cracks. Here, "the vertical joints and horizontal joints corresponding to at least one of the other pieces are open joints or sealing joints with deformable ability" means that it includes a form in which only the joints around the other piece are open joints, etc., a form in which only the joints around two pieces including the other piece are open joints, etc., and a form in which the joints around the entire periphery of the second accessory tile are open joints, etc. Effect of the Invention

[0030] 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 protruding corners of buildings due to differences in deformation between the accessory tiles and the base material, which have different linear expansion coefficients.

[Figure 6] FIG. 11 is a perspective view of a portion of a tiled protruding corner according to a fourth embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0032] Hereinafter, an example of a tiled protruding corner according to each embodiment will be described with reference to the accompanying drawings. In this specification and the drawings, substantially identical components may be designated by the same reference numerals to avoid redundant description.

[0033] [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.

[0034] The tiled protruding corner 90A is formed by attaching a plurality of first accessory tiles 20 which 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.

[0035] At the corner portion of the protruding 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.

[0036] The first accessory tile 20 in the illustrated example has two pieces 21 that form an L shape and are the same length, but one of the two pieces may be relatively long and the other piece may be relatively short.

[0037] The adhesive layer 40 is formed from an organic adhesive, and examples of the organic adhesive include modified silicone resin adhesives, modified silicone-epoxy resin adhesives, etc. The adhesive layer 40 may be formed from mortar, but as described above, it is preferable to form it from an organic adhesive in order to prevent the tiles from peeling or falling off.

[0038] Both the vertical joints 51 and the horizontal joints 52 are mortar joints. The mortar joints are formed by adhering each of the first feature tiles 20 and each of the flat tiles 30 to the adhesive layer 40, and then applying mortar to the horizontal joints.

[0039] Of the two pieces 21 of the first accessory tile 20, one piece 21 is attached to the side surface 12 of the base material 10 via an adhesive layer 40, while the other piece 21 is not attached to the side surface 11 of the base material 10 via a non-adhesive layer 45.

[0040] In this manner, one of the two pieces 21 of the first accessory tile 20 is not affixed to the surface of the base material 10, which prevents the base material 10 from exerting a tensile force P (or a binding force) on one of the pieces 21 due to the difference in deformation between the first accessory tile 20 and the base material 10 when the temperature changes, as shown in Fig. 3, and this eliminates the bending and shearing forces caused by this tensile force P, thereby suppressing the bending and shearing 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 Figs. 1 and 2).

[0041] [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.

[0042] The tiled protruding corner 90B differs from the tiled protruding corner 90A shown in Figure 3 in that the vertical joint on the side of one piece 21 that is not attached to the side surface 11 of the base material 10 via the non-adhesive layer 45 is an open joint 51B.

[0043] By having the vertical joint 51 on the side of one piece 21 be an open joint 51B instead of the mortar joint 51A shown in Fig. 3, the one piece 21 and the flat tile 30 on its side are completely separated, and the first part tile 20 is prevented from receiving a binding force from the flat tile 30 on its side when the temperature of the first part tile 20 changes. Therefore, in addition to preventing the tensile force P from acting from the base material 10 due to the configuration in which the one piece 21 is not attached to the surface of the base material 10, the open joint 51B eliminates the binding force from the flat tile 30 on the side, further enhancing the effect of suppressing the occurrence of cracks that may occur in the first part tile 20.

[0044] In addition, a sealing joint with a deformable property may be applied instead of the open joint 51B. In this form, it becomes possible to absorb the binding force (tensile force) from the flat tile 30 by the deformation of the sealing joint, and the effect of eliminating the binding force from the flat tile 30 can be expected in the same way as with the open joint.

[0045] [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.

[0046] Unlike the tiled projection corners 90A, 90B already described with reference to Figures 3 and 4, the tiled projection corner 90C shown in Figure 5 is formed by attaching a second accessory tile 70 having three intersecting pieces 71, a plurality of first accessory tiles 20 which are L-shaped in a 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 projection corner D2 where the three side surfaces that make up the building intersect.

[0047] A second accessory tile 70 is arranged at the corner portion 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.

[0048] The vertical joints 51 and horizontal joints 52 around the entire periphery of the second feature tile 70, the joints between the first feature tiles 20, and the joints between the first feature tiles 20 and the flat tiles 30 are all mortar joints.

[0049] Of the three pieces 71 of the second feature tile 70, two vertical pieces 71A are not attached to the side of the base material 10 via a non-adhesive layer 45, and the other horizontal piece 71B is attached to the side of the base material 10 via an adhesive layer (not shown).

[0050] In this way, one piece 71B of the second accessory tile 70 at the corner of the protruding corner D2 where the three sides intersect is attached to one side of the base material 10 via an adhesive layer, and the other two pieces 71A are not attached to the other two sides of the base material. Even if there is a deformation difference between the second accessory tile 70 and the base material 10 due to temperature changes, this deformation difference prevents the tensile force P from acting on the two pieces 71A (the pieces attached to the base material 10), and the bending and shearing forces caused by this tensile force P can be eliminated, suppressing the bending and shearing forces occurring in the second accessory tile 70. This makes it possible to suppress or prevent the occurrence of cracks that may occur in the second accessory tile 70.

[0051] The two pieces 71 that are not attached to the side surface of the base material 10 via the non-adhesive layer 45 may be a horizontal piece 71B and one of the vertical pieces 71A, other than the example shown in the figure.

[0052] [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.

[0053] The tiled protruding corner 90D differs from the tiled protruding corner 90C shown in FIG. 5 in that one piece 71 (horizontal piece 71B in the illustrated example) is not attached to the side of the base material 10 via a non-adhesive layer 45, and in that the joints around this horizontal piece 71B are open joints 51B instead of mortar joints.

[0054] In this way, the two pieces 71A of the second accessory tile 70 at the corner of the protruding corner D2 where the three sides intersect are attached to one side of the base material 10 via an adhesive layer, and the other piece 71B is not attached to the other side of the base material, and the joint around this other piece 71B is an open joint 51B. Even if there is a deformation difference between the second accessory tile 70 and the base material 10 due to a temperature change, this deformation difference prevents the tensile force P from acting on one piece 71B (the piece attached to the base material 10), and the bending and shearing forces caused by this tensile force P can be eliminated, and the bending and shearing forces generated in the second accessory tile 70 are suppressed. This makes it possible to suppress or prevent the occurrence of cracks that may occur in the second accessory tile 70.

[0055] In addition, the piece 71 that is not attached to the side surface of the base material 10 via the non-adhesive layer 45 may be either one of the vertical pieces 71A other than the illustrated example, and in that case, the joint around the vertical piece 71A becomes the open joint 51B. Also, instead of the open joint 51B, a sealing joint with deformation performance may be applied.

[0056] The present invention is not limited to the configurations shown here, and may be implemented in other embodiments in which other components are combined with the configurations and the like set forth in the above embodiments. In this regard, the present invention may be modified without departing from the spirit of the present invention, and may be appropriately determined according to the application form.
