Description

  The present invention relates to a tile floor finishing structure that is used for floor finishing of verandas, terraces, entrances, approaches, and the like, is less likely to cause cracks and chippings in tiles, and has excellent durability.

  Ceramic tiles that are widely used for various finishing surfaces are generally vulnerable to impact loads with bending stress. Therefore, if a dry construction method that easily generates bending stress is used as a floor finish that generates large stresses when a heavy heavy object is accidentally dropped on the floor, cracking is likely to occur and the appearance is reduced and repair work is performed. Needed to be done frequently. Therefore, the tile finishing of the floor is carried out by using a so-called wet method in which the entire back surface of the tile is fixed with a base mortar. When this wet construction method is used, even if it receives an impact load due to heavy load dropping or the like, it can be received in a distributed manner, so that bending stress hardly occurs. Furthermore, in order to improve the workability and strength in this wet method, a proposal has been made to use mortar containing special reinforcing fibers such as polyamide fibers (for example, see Patent Document 1).

JP 2003-97021 A

  However, tile construction by the wet method requires skill and variation in construction quality, and further includes complicated processes such as blending and curing of mortar, resulting in poor workability, prolonging the construction period and cost. There was a problem that became high.

  The present invention is based on the use of tiles having a water absorption rate of more than 1%, does not cause damage such as cracks, and provides a tile floor finish structure using a dry construction method with excellent workability. It is said.

  In order to solve the above-mentioned problems, the present inventor repeatedly performed trial manufacture and construction experiments regarding various tile finishing specifications. As a result, tiles with a water absorption rate exceeding 1% including porcelain tiles and porcelain tiles are excellent in impact resistance and may cause damage such as cracks even if they are used for floor finishing by the dry method. As a result, the present invention has been devised. The invention according to claim 1 is a tile floor finishing structure in which a plurality of plate-like tiles are laid on the surface of the floor substrate by a dry method, and the surface of the floor substrate is formed flat as a whole. In addition, a partial gap is formed between the surface of the floor base and the back surface of the tile, and the tile has a water absorption rate exceeding 1%.

  The invention according to claim 2 is an adhesive construction method in which the dry construction method adheres the tile to the floor foundation with a stick-like adhesive applied between the surface of the floor foundation and the back surface of the tile, It is characterized by being formed by gaps between the adhesives applied in the form of rods.

  The invention according to claim 3 is the unit construction method in which the dry construction method is a unit construction method in which a tile unit in which tiles are arranged in advance on a unit frame is fixed to a floor base and the tile is laid on the floor base. It is characterized in that it is formed by a gap between the tile back surface that is lifted and fixed by the body from the floor base and the floor base.

  In the invention according to claim 4, the gap is formed by a drainage groove that is recessed in at least one of the surface of the floor base and the back surface of the tile. In the invention according to claim 5, the tile is a waste glass tile. It is characterized by being.

  In the invention according to claim 1, since a partial gap is formed between the floor base surface formed entirely flat and the back surface of the tile, a large bending stress is applied to the tile due to an impact caused by falling object collision. Will occur. However, tiles with a water absorption rate exceeding 1% have high shock absorption capability due to their self-crashing properties. As a result, there is no damage such as cracking or chipping. Is possible.

  As in the invention according to claim 2, when the tile is adhered and fixed to the floor base with the adhesive applied to the back surface of the tile, the tile can be efficiently constructed without requiring skill. In addition, since the tile has a high impact absorption capability as described above, even if a falling object impact force is applied to the gap formed by the gap between the stick-coated adhesives, damage such as cracks is caused. It does not occur.

  As in the invention according to claim 3, adopting the unit construction method and laying the tile on the floor base by fixing the tile unit in which the tile is previously arranged on the unit frame to the floor base, the workability is improved. Therefore, complicated operations such as joint assignment can be performed without requiring skill. Moreover, since tiles with excellent water absorption capacity exceeding 1% are used, even if a gap is formed by the gap between the tile lifted from the floor base by the unit frame and the floor base, it will crack. No chipping occurs, and a highly sensitive appearance can be maintained over a long period of time.

  If the drainage groove is provided in at least one of the surface of the floor base and the back surface of the tile as in the invention according to claim 4, the drainage performance of the floor surface is improved, and water does not accumulate even during heavy rain. In addition, since tiles having high impact absorbing ability are used, cracks and chips are not generated even when the tile portion straddling the drainage groove is subjected to an impact drop at the time of loading.

  The waste glass tile employed in the invention according to claim 5 is rich in self-crash property of the surface layer because the water absorption exceeds 1%, and even if a gap is formed between the tile back surface and the floor base, the drop impact force Is relaxed and damage is less likely to occur. Moreover, the use of waste glass tiles can contribute to resource saving and energy saving by reusing glass resources such as glass bottles and building waste.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the tile floor finishing structure 1 is configured by laying a plurality of tiles 3 on the surface of a floor base 2 using a dry construction method.

  The floor base 2 varies depending on the part to be tiled. For example, in the entrance approach, it is a slab-like base made of cement concrete that extends continuously from the fabric foundation with the entrance opening in the upper part, or on the upper floor veranda from a building rectangle to a bowl shape. Veranda-structured rectangular body that extends outward. These floor bases 2 are formed flat on the entire surface in order to place tiles for finishing.

  The tiles 3 are generally rectangular plates, and a plurality of tiles 3 are arranged at the same height via joints and are continuously laid on the floor base 2. The tile 3 may be formed in a circle, an ellipse, a triangle, or the like.

  The tile 3 having a water absorption rate exceeding 1% is used. As the tile 3 having such a water absorption rate, a stoneware tile or a ceramic tile can be used. The porcelain tile is a tile baked at around 1200 ° C. and has a water absorption rate of 5% or less and has a property of absorbing water slightly. And it is generally colored and opaque, and has the property of producing a clear sound when tapped lightly. In addition, it is often used by making use of the characteristics of tiles with a natural texture that makes use of the simple color unevenness that can be made when baking earth like unglazed, without coloring with glaze.

  The porcelain tile is a tile fired at 1000 ° C. or higher, has the softest physical properties among the tiles, has a water absorption rate of 22% or less, and has high water absorption. It also has the property of producing muddy sound when hit. There are many glazed tiles finished with glaze, and they are widely used as decorative finish tiles because of their rich colors and designs and transparency. In addition, the stoneware tile and the earthenware tile where the water absorption rate exceeds 1% have a higher foaming rate than the porcelain tile whose water absorption rate is 1% or less. Accordingly, since a crash is likely to occur on the surface layer of the collision portion when receiving a drop impact, the drop impact force is absorbed and relaxed, and thus the generation of stress due to the impact is suppressed.

  Further, as the tile 3, a waste glass tile obtained by firing a raw material obtained by adding mineral fine powder such as fly ash and blast furnace water slag to waste glass at a relatively low temperature can be used. Since this waste glass tile has a water absorption rate of more than 1% and not more than 3%, it has an excellent ability to absorb shock due to self-crash compared to a porcelain tile having a water absorption rate of 1% or less as described above.

  A large amount of plate glass is used in buildings, automobiles, and the like, and it is also used in large quantities as glass for containers such as bottles that contain various types of drinking water. In other words, when rebuilding an aging building, one-way bins are discarded after being used once, and new products are also used for recycling bins due to the occurrence of damage or the inability to remove contaminants after several uses. Updated to Thus, by reusing a large amount of discarded materials as a raw material for waste glass tiles, it can greatly contribute to resource saving and energy saving.

  The said dry construction method which is a construction system which lays the tile 3 in the floor base 2 means what includes construction methods other than the wet construction method using the conventional cement mortar. In this embodiment, as shown in FIGS. 1 and 2, an adhesive 5 such as an epoxy-based adhesive, an acrylic emulsion-based adhesive, or a synthetic rubber latex-based adhesive is continuously provided in a meandering manner on the back surface of the tile 3. A stick-shaped coating is applied, and the adhesive 5 is used to bond the tile 3 to the floor base 2.

  In the bonding method using the bar-shaped application, the tile 3 is supported by the thickness 5 of the adhesive 5 floating from the surface of the floor base 2, and the surface of the floor base 2 is formed by the gap between the bar-coated adhesive 5. A partial gap 4 is formed between the back surface of the tile 3. When such a gap 4 is formed, impact bending stress is generated in the tile 3 when a hard heavy object is accidentally dropped. However, since the tile 3 having a water absorption rate exceeding 1% has a high foaming rate as described above, the impact absorbing ability by self-crash is large, and the impact load can be suppressed. As a result, breakage such as cracking and chipping is eliminated, and it can be used for a long time as a floor finish. In addition, in this embodiment, the tile 3 is bonded and fixed to the floor base 2 with an adhesive applied to the back surface of the tile 3, so that complicated management such as a wet method is unnecessary, so that it is skilled in work. Can be tiled efficiently without the need for

  3 and 4 illustrate other embodiments. Hereinafter, different contents will be described, and other than that, only the same reference numerals are given to the main components shown in the figure. As the dry construction method of this embodiment, a unit construction method in which tile finishing is performed by fixing the tile unit 7 in which the tiles 3 are previously arranged on the upper part of the unit frame 6 to the floor base 2 is used.

  As shown in FIG. 3, the unit frame 6 of the present embodiment has a plurality of small holes 21 regularly arranged in the vertical and horizontal directions and a rectangular plate-like substrate 6 </ b> A that is substantially the same size as the tile 3, and the small holes 21. In FIG. 2, the cylindrical leg portions 6B are suspended from the lower surface of the substrate 6A, and are integrally formed using a plastic material such as polyethylene resin, polypropylene resin, polystyrene resin, phenol resin, unsaturated polyester resin. . In addition, ring-shaped connecting portions 22 are provided on two continuous sides of the substrate 6A, and the legs 6B of adjacent tile units 7 are inserted and engaged so that they can be connected together. Yes.

  A tile 3 of the same size is fixed in advance on the unit frame 6 with an adhesive to constitute a tile unit. Then, as shown in FIG. 4, a plurality of tile units 7 are laid on the floor base 2 and connected to each other by the engagement of the connecting portions 22 and the leg portions 6B. As a result, the tile units 7 are connected to the floor base. 2 is fixed on. Further, when the tile unit 7 is bonded to the floor base 2, it is possible to prevent displacement. A tile unit 7 in which a plurality of tiles 3 are attached to one unit frame 6 may be used. The tile unit construction method is excellent in that workability is improved at the construction site and work requiring skill such as joint allocation can be easily performed, so that a finish without variations can be obtained.

  When the tile unit 7 is configured as described above, the tile 3 itself is lifted and fixed from the floor base 2 by the unit frame 6, so that the thickness of the back side of the tile 3 is from the floor base 2 to the unit frame 6. Is raised and arranged. Moreover, since the unit frame 6 is provided with many small holes 21 as described above, a gap 4 is formed between the back surface of the tile 3 and the floor base 2 inside the small holes 21. Accordingly, since such a gap 4 acts as a heat insulating space, a high temperature can be prevented on the rooftop or the like. However, if a heavy heavy object is accidentally dropped on the surface of the tile 3, a large impact stress is generated in the gap 4, and damage to the porcelain tile is likely to occur, but the impact absorption is more than 1%. Since the tile 3 having high ability is used, even if the gap 4 is formed by the gap with the floor base 2, cracks are not generated and a highly sensitive appearance can be maintained for a long period of time.

  5 and 6 illustrate still other embodiments. In the tile 3 of this embodiment, a plurality of drain grooves 8 extending in parallel to the back surface thereof are formed. And it adheres to the floor base 2 with the adhesive 24 applied to the convex part 23 except this drainage groove 8. Since the drainage performance of the floor surface is improved by the continuous drainage groove 8 as described above, a sufficient water drainage can be obtained even during heavy rain, so that no puddle is generated. Moreover, since the tile 3 having an impact absorption capacity exceeding 1% is used, even if a drop impact load is applied to the tile portion straddling the drainage groove during loading, there is no crack chipping. High durability is obtained.

  FIG. 7 illustrates an embodiment in which the drainage grooves 8 are recessed in the floor base 2. In this case, the flat tile 3 is fixed by applying the adhesive 24 to the convex portion 25 of the floor base 2.

  As shown in Table 1 as Examples 1 to 5, five types of tiles 3 having a water absorption rate exceeding 1% were made as an experiment. The water absorption rate of the tile was measured using JIS A5209. Then, various tiles 3 coated with a synthetic rubber latex adhesive were sticked on a floor base 2 formed by placing concrete and formed flat and flat, and the strength of the various tiles was tested after adhesion curing. The gap between the tile 3 and the floor base 2 (indicated by t1 in FIG. 2) by the adhesive layer is 1.25 mm, and the distance between the adhesives in which the adhesive is applied in a meandering rod shape (in FIG. 1). (indicated by d1) is 40 mm. At the same time, two types of porcelain tiles having a water absorption rate of 1% or less were prepared as comparative examples and subjected to a strength test in the same manner.

  The strength test method is to install the tile in the product state, drop a 225g steel ball from the height of 60cm in the approximate center of the tile, and visually and magnifier (15 times) the appearance abnormality such as cracking and peeling of the tile surface. confirmed.

  As a result, no damage was caused on the five types of tiles 3 of Examples 1 to 5. In the porcelain tiles of Comparative Examples 1 and 2, occurrence of cracks was observed in both bodies.

  The above description is an example of the embodiment of the present invention. Therefore, the technical scope of the present invention is not limited to this, and various modifications are included in addition to the above-described embodiment.
