Description

[Technical Field]

[0001] The present invention relates to a finishing material, a manufacturing method for the finishing material, and a method for finishing a wall surface. [Background technology]

[0002] A conventional wall finishing method involves attaching multiple tiles to the wall surface using an adhesive. For example, Patent Document 1 discloses a method of attaching multiple tiles, each connected to the backside with a connecting member, to the wall surface. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-265733 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the construction method of Patent Document 1, although each tile that makes up a tile unit is connected with a connecting member, the tiles between adjacent tile units are connected only with adhesive, so there is room for improvement in preventing tiles from falling off. [Means for solving the problem]

[0005] The finishing material that solves the above problem comprises a tile unit having a tile and a first connecting member that connects adjacent tiles, and a second connecting member that extends beyond the end of the tile unit and connects adjacent tile units.

[0006] A manufacturing method for finishing materials that solves the above problem includes a first connecting step of manufacturing a tile unit by connecting the back surfaces of adjacent tiles with a first connecting member, and a second connecting step of connecting a second connecting member to the tile unit so that it extends beyond the end of the tile unit.

[0007] A wall finishing method that solves the above problem involves adhering a finishing material having a tile unit with a tile and a first connecting member that connects adjacent tiles, and a second connecting member that extends beyond the end of the tile unit and connects adjacent tile units, to the wall surface with an adhesive.

[0008] This makes it possible to form a tile unit in which tiles are firmly connected to each other by the first connecting member, and to form a finishing material in which tile units can be firmly connected to each other by the second connecting member.

[0009] It is preferable that the surface area of ​​the finishing material be 60% or more of the back surface of each tile that is not covered by the first and second connecting members, thereby making it possible to make the surface area of ​​each tile that is directly adhered to the wall surface via an adhesive 60% or more.

[0010] The finishing material may have an overlapping portion between the first connecting member and the second connecting member, whereby when the finishing material is attached to the wall surface with an adhesive, the first connecting member and the second connecting member can be connected at the overlapping portion via the adhesive.

[0011] In the finishing material, it is preferable that the first connecting member and the second connecting member are net members, and that the porosity thereof is 40% or more and 80% or less. This ensures the strength of the first connecting member and the second connecting member themselves, while increasing the proportion of the area covered by the first connecting member and the second connecting member where the tile is directly adhered to the wall surface via adhesive.

[0012] In the above-described wall finishing method, a fastener may be hammered into the joints between the adjacent tiles, thereby more effectively preventing the tiles from falling off. [Brief explanation of the drawings]

[0014] An embodiment of a finishing material, a manufacturing method for a finishing material, and a method for finishing a wall surface will be described with reference to Figures 1 to 10. The finishing material is a member that is attached in order to a wall surface to which an adhesive has been applied, thereby covering the wall surface.

[0015] (Finishing materials) As shown in Fig. 1, the finishing material 10 has a tile unit 11. The tile unit 11 has a plurality of rectangular tiles 12 and a first connecting member 13. The length of one side of the tile 12 is 45 mm or more and 300 mm or less.

[0016] The tile unit 11 is formed into a rectangular shape as a whole by arranging a plurality of tiles 12 in a matrix. In this embodiment, the plurality of tiles 12 are arranged in a matrix of 6 rows and 3 columns. In FIG. 1, the top row is the first row and the bottom row is the sixth row. The leftmost column is the first column and the rightmost column is the third column.

[0017] The first connecting members 13 are adhered to the rear surfaces of the tiles 12, for example, with an organic adhesive. The first connecting members 13 cover a portion of the rear surfaces of the tiles 12. The first connecting members 13 connect adjacent tiles 12. In this embodiment, the first connecting members 13 connect the bottoms of the tiles 12 in odd-numbered rows to the tops of the tiles 12 in even-numbered rows. The first connecting members 13 also connect the tiles 12 in adjacent columns. The first connecting members 13 may be composed of one member that connects all the tiles 12, or may be composed of multiple members that connect, for example, a pair of tiles 12.

[0018] The finishing material 10 has second connecting members 15. The second connecting members 15 are adhered to the rear surfaces of the tiles 12 that form the periphery of the tile unit 11, for example, with an organic adhesive. The second connecting members 15 cover a portion of the rear surface of the tiles 12. The second connecting members 15 protrude from the ends of the tile units 11. The second connecting members 15 connect the tiles 12 between adjacent tile units 11. In the tile units 11 that are rectangular as a whole, as in this embodiment, the second connecting members 15 are provided so as to protrude from two sides that sandwich one corner. Specifically, the second connecting members 15 are provided so as to protrude upward from the tiles 12 that form the first row and to protrude to the right from the tiles 12 that form the third column. The second connecting members 15 may be composed of a single L-shaped member or multiple members.

[0019] The first connecting member 13 and the second connecting member 15 are arranged so that the ratio (adhesion rate) of the uncovered area (adhered area) of each tile 12 is 60% or more of the total area of ​​the back surface. The official pass / fail judgment for tiling is that the adhesive adhesion rate to the back surface of the tile is 60% or more and is evenly adhered to the entire surface of the tile. If the "ratio of the uncovered area is 60% or more," the tiling is considered safe. Furthermore, the first connecting member 13 and the second connecting member 15 are preferably flexible to prevent damage during transportation or handling. The finishing material 10 may also have an overlapping portion 17 where the first connecting member 13 and the second connecting member 15 overlap.

[0020] An example of the first connecting member 13 and the second connecting member 15 is a net member formed of glass fiber, polyamide fiber, polypropylene fiber, polyacrylic fiber, polyvinyl alcohol fiber, polyethylene fiber, vinylon fiber, carbon fiber, etc. Another example of the first connecting member 13 and the second connecting member 15 is a resin sheet.

[0021] When the first connecting member 13 and the second connecting member 15 are net members, the porosity thereof is preferably 40% or more and 80% or less, and more preferably 60% or more and 80% or less. A porosity of 40% or more makes it easier to ensure the proportion of the portion of the tile 12 that is directly adhered to the wall surface via adhesive in the covered portion by the first connecting member 13 and the second connecting member 15 (adhesion rate in the covered portion). A porosity of 60% or more makes it even easier to ensure the adhesion rate in the covered portion. Furthermore, a porosity of 80% or less can impart sufficient strength to the first connecting member 13 and the second connecting member 15 themselves.

[0022] As shown in FIG. 2 , an example of the first connecting members 13 is a net member with a triangular mesh portion. By using such a net member for the first connecting members 13, the tiles 12 can be connected in a manner in which a portion of the first connecting members 13 extends diagonally relative to the juxtaposition direction of the tiles 12. The lower limit of the connecting adhesive length L between the tiles 12 and the first connecting members 13 is approximately 20 mm, and the upper limit is approximately the length of the long side of the tile divided by two. An example of the upper limit is 50 mm. The connecting adhesive length L is the length in the juxtaposition direction of the tiles 12, and is the length from the edge of the tile 12 to the tip of the first connecting member 13 at the joint between the tile 12 and the first connecting member 13. Having the connecting adhesive length L of 20 mm or more facilitates the application of sufficient connecting strength between the tiles 12. Having the connecting adhesive length L of 50 mm or less facilitates the provision of an area in which the tiles 12 are directly bonded to the wall surface via an adhesive.

[0023] Such a net member can also be applied to the second connecting member 15. The protruding length of the second connecting member 15 from the end of the tile 12 is set to a length that takes into consideration the joints between the tile units 11 and that makes the connecting adhesive length L with the tile 12 of the adjacent tile unit 11 20 mm or more and 50 mm or less.

[0024] (Regarding connecting adhesive length) The above-mentioned connecting bond length L was derived based on the results of experiments conducted by the present inventors.

[0025] As shown in Figure 3(a), in this experiment, an adhesive 21 whose main component was a modified silicone resin was applied to an acrylic plate 20 with a film attached to its surface, and then a pair of tiles 12 (45 mm x 90 mm) connected with a test connecting member 23 was attached to the adhesive 21. The test connecting member 23 in this experiment was a net member made of polyamide fiber with a triangular mesh. An adhesive layer approximately 2 mm thick was formed between the acrylic plate 20 and the entire back surface of each tile 12, and approximately 3 mm thick was formed in the joint areas 26.

[0026] 3(b), after the adhesive 21 had sufficiently dried and hardened, the acrylic plate 20 was peeled off together with the film to obtain a test specimen 25. The tiles 12 were then pulled apart at a rate of 6 mm / min to measure the maximum load required to break the joints 26. A comparative specimen was made by connecting tiles 12 with only the adhesive 21.

[0027] FIG. 4 shows the shape of the test connecting member 23 used in this experiment. 4(a), the first test connecting member 31 is a rectangular net member. Of the test specimens in which tiles 12 were connected with this first test connecting member 31, the one with a connection adhesive length L of 20 mm was designated as test specimen 1-1, and the one with a connection adhesive length L of 50 mm was designated as test specimen 1-2.

[0028] As shown in Fig. 4(b), the second test connecting member 32 is a net member in the shape of a rectangular parallelogram frame. Of the test specimens in which tiles 12 were connected with this second test connecting member 32, the one with a connection adhesive length L of 20 mm was designated as test specimen 2-1, and the one with a connection adhesive length L of 50 mm was designated as test specimen 2-2.

[0029] The experimental results are shown in Figure 5. As shown in Figure 5, the maximum load of each test specimen was greater than the maximum load of the comparison specimen. Even for specimen No. 2-1, which had the smallest maximum load among the test specimens, its maximum load was approximately three times that of the comparison specimen.

[0030] For the first test connecting member 31, the maximum loads of the No. 1-1 and No. 1-2 test specimens were approximately the same. For the second test connecting member 32, the maximum load of the No. 2-2 test specimen was 1.5 times or more the maximum load of the No. 2-1 test specimen. In addition, the maximum load of the No. 2-2 test specimen was approximately the same as or greater than the maximum load of the No. 1-1 test specimen.

[0031] For this reason, the connecting adhesive length L should be set to 20 mm or more and 50 mm or less, taking into consideration the size of the tile 12, which has a side length of 45 mm or more and 300 mm or less, and the adhesion rate between the tile 12 and the wall surface, so that sufficient connecting strength can be obtained between the tiles 12.

[0032] (Example of the shape of the second connecting member) An example of the second connecting member 15 in this embodiment will be described with reference to Figures 6 and 7. Note that in Figures 6 and 7, the portions of the tile 12 whose back surfaces are covered by the first connecting member 13 and the second connecting member 15 are omitted. Also, only a portion of the first connecting member 13 is shown.

[0033] As shown in FIG. 6(a), the second connecting member 15 is composed of a rectangular net member 15a that is adhered separately to each tile 12 that makes up the first row and each tile 12 that makes up the third column.

[0034] As shown in Figure 6(b), the second connecting member 15 is composed of a rectangular frame-shaped resin sheet 15b that is separately adhered to each tile 12 that makes up the first row and each tile 12 that makes up the third column.

[0035] As shown in FIG. 7(a), the second connecting member 15 is composed of a cross-shaped net member 15c that is adhered to each of the tiles 12 that make up the first row and each of the tiles 12 that make up the third column.

[0036] As shown in Figure 7(b), the second connecting member 15 is composed of a pair of linear resin sheets 15d that are individually adhered to each tile 12 that makes up the first row and each tile 12 that makes up the third column.

[0037] The rectangular net member 15a, the square frame-shaped resin sheet 15b, the cross net member 15c, and the linear resin sheet 15d can also be applied to the first connecting member 13 after adjusting their sizes.

[0038] As shown in Figure 7(c), the second connecting member 15 is composed of a rectangular net member 15e that is adhered so as to straddle each tile 12 that constitutes the first row, and a rectangular net member 15f that is adhered so as to straddle each tile 12 that constitutes the third row.

[0039] As shown in Figure 7(d), the second connecting member 15 is composed of a ladder-shaped resin sheet 15g that is adhered so as to straddle each tile 12 that constitutes the first row, and a ladder-shaped resin sheet 15h that is adhered so as to straddle each tile 12 that constitutes the third row.

[0040] The ladder-shaped resin sheet 15g adhered to each tile 12 in the first row is composed of a rectangular outer frame and a pair of intermediate frames adhered to the intermediate tile 12, specifically the tiles 12 in the second row.

[0041] The ladder-shaped resin sheet 15h adhered to each tile 12 in the third row is composed of a rectangular outer frame and an intermediate frame adhered to the tiles 12 located in the middle, specifically the tiles 12 in the second to fifth rows.

[0042] (Finishing material manufacturing method) As shown in FIG. 8, the manufacturing method of the finishing material 10 includes a first connecting step (step S101) and a second connecting step (step S102).

[0043] In the first connecting step (step S101), tiles 12 are connected with first connecting members 13 to form tile units 11. Specifically, for example, after arranging a plurality of tiles 12 in a predetermined array, the first connecting members 13 are adhered to the rear surfaces of the tiles 12 with an adhesive so that adjacent tiles 12 are connected.

[0044] In the second connecting step (step S102), the second connecting member 15 is adhered to the tile unit 11. Specifically, the second connecting member 15 is adhered to the rear surface of the tile 12 with an adhesive so that a portion of the second connecting member 15 protrudes from the tile 12 that forms the peripheral edge of the tile unit 11.

[0045] (Wall finishing method) As shown in FIG. 9, the method for finishing a wall surface using finishing material 10 includes a base preparation process (step S201), a tiling process (step S202), a joint filling process (step S203), an expansion / contraction adjustment process (step S204), a curing process (step S205), and a cleaning process (step S206).

[0046] In the base preparation process (step S201), the wall surface is smoothed by applying a base preparation coating material to any unevenness or unevenness. In addition, dirt is removed from the wall surface, and laitance and other debris that has appeared on the wall surface are also removed.

[0047] In the tiling process (step S202), an adhesive is applied evenly to the surface of the wall using a metal trowel or the like, and then a comb trowel or the like is used to create a groove in the adhesive. Examples of the adhesive that can be used include organic adhesives whose main component is modified silicone resin, and cement-based adhesives such as mortar. The finishing materials 10 are then attached in order so that the tile units 11 are connected to each other with the second connecting members 15, and the finishing materials 10 are then vibrated using a hammer or the like. The finishing materials 10 are attached in order so that, in addition to the regular joints, expansion adjustment joints wider than the regular joints are formed in predetermined locations.

[0048] In the joint filling step (step S203), after confirming that the adhesive has hardened, the normal joints are filled with joint mortar. In the expansion adjustment joint sealing step (step S204), the expansion adjustment joint area is cleaned and a backup material is placed, and then an expansion adjustment primer is applied to the expansion adjustment joint area and a sealant is placed.

[0049] In the curing process (step S205), the wall surface to which the finishing material 10 is attached is cured so that the adhesive, joint mortar, and sealant for the expansion adjustment joints are sufficiently hardened. For example, if there is a risk of damage from strong direct sunlight, strong winds, rainfall, etc., a sheet is used for curing. Also, if there is a risk of sudden drying or freezing, for example, cold protection and heat retention equipment is used to prevent sudden drying or freezing.

[0050] In the cleaning step (step S206), the surfaces of the tiles 12 are cleaned by removing adhesives, joint mortar, and the like that have adhered to the surfaces of the tiles 12. Through this series of steps, the finishing material 10 is attached to the wall surface.

[0051] As shown in FIG. 10 , the wall finishing method may include a fastener driving step after the tiling step (step S202) or the joint filling step (step S203). In the fastener driving step, a driving hole extending into the wall is formed in the tile 12 or the joint 34 using a drill or the like, and then a fastener 35 such as an anchor pin is driven into the driving hole. While the fastener 35 is preferably installed in the joint 34 for aesthetic reasons, it may also be driven into the tile. Note that in FIG. 10 , the tiles 12 of each tile unit 11 are hatched with the same type of pattern. The lower reference numeral 15 indicates the second connecting member 15 of the finishing material 10 located at the bottom left. The upper reference numeral 15 indicates the second connecting member 15 of the finishing material 10 located at the top left.

[0052] The effects of this embodiment will be described. (1) In the finishing material 10, each tile 12 constituting the tile unit 11 is firmly connected to the other tiles 12 via the first connecting members 13. In addition, by attaching the finishing material 10 to the wall surface in order, each tile unit 11 is firmly connected to the other tile units 11 via the second connecting members 15.

[0053] As a result, the tiles 12 attached to the wall surface are all connected by the first connecting members 13 and the second connecting members 15, making it possible to make the tiles 12 less likely to fall off. (2) On the back surface of each tile 12, the area of ​​the portion not covered by the first connecting member 13 and the second connecting member 15 is 60% or more. This ensures that the area of ​​the portion on the back surface of each tile 12 that is directly adhered to the wall surface via the adhesive is sufficient. As a result, tiling using the finishing material 10 can be made safe.

[0054] (3) The finishing material 10 has an overlapping portion 17 where the first connecting member 13 and the second connecting member 15 overlap. As a result, by attaching the finishing material 10 to the wall surface with an adhesive, the first connecting member 13 and the second connecting member 15 can be firmly connected using the adhesive.

[0055] (4) The first connecting member 13 and the second connecting member 15 are net members with a porosity of 40% to 80%. This provides sufficient strength to the first connecting member 13 and the second connecting member 15, while also ensuring that the proportion of the portion of the tile 12 that is directly bonded to the wall surface via an adhesive is maintained in the portion covered by the first connecting member 13 and the second connecting member 15. This effect was confirmed through the above-mentioned experiments and the like.

[0056] (5) In the finishing material 10, the second connecting members 15 are provided so as to extend beyond two sides of one corner of the rectangular tile unit 11. This allows the finishing materials 10 to be attached to the entire wall surface by attaching them in order without the second connecting members 15 overlapping.

[0057] (6) By driving in the fixing device 35, the tile 12 becomes even less likely to fall off. This embodiment can be modified as follows: This embodiment and the following modifications can be combined and implemented within the scope of technical compatibility.

[0058] The finishing material 10 may have a removable temporary fixing sheet attached to the tile unit 11 so as to cover the front surfaces of all tiles 12. This configuration improves the handling and transportability of the finishing material 10.

[0059] The finishing material 10 does not need to have the overlapping portion 17 between the first connecting member 13 and the second connecting member 15. Also, the first connecting member 13 and the second connecting member 15 may be integrated. [Explanation of symbols]
