Description

  The present invention relates to a tile sheet formed by connecting a plurality of tiles in a sheet and a method of manufacturing the tile sheet.

  Conventionally, a tile sheet formed by connecting a plurality of tiles in a sheet shape has been used for the purpose of improving the workability of exterior tiles. In such tile sheets, each tile is arranged vertically and horizontally through the joint space, and is adhered to the wall of the building through the adhesive mortar, and a plurality of tiles are attached at one time by embedding the mortar in the joint space. Can. Heretofore, as this type of tile sheet, there has been provided a sheet in which tiles are connected by paper pasted with starch paste on the tile surface. However, in the case of the conventional tile sheet, after bonding the tile sheet to the building wall, it is necessary to water the surface of the tile to remove the paper, and the peeled paper becomes a large amount of waste. In addition, such tile sheets are easily peeled off from the paper if they are left under high humidity conditions or wet with water due to rain etc. Therefore, they are packed in a cardboard carton and carried to the site so as not to hit the rain. After use, not only paper stuck to tiles but also cardboard cartons used for packaging will be generated in large quantities as waste on the site. For this reason, such a tile sheet has been strongly demanded by the field.

  Therefore, a tile sheet is proposed in which a plurality of tiles arranged longitudinally and laterally are connected by a non-woven fabric via an ultraviolet curable adhesive (for example, Patent Document 1). Specifically, a plurality of tiles are arranged vertically and horizontally through the joint space, and a plurality of non-woven fabrics are arranged on the back of the tile so as to bridge the joint space, and the back of each tile and the non-woven fabric are ultraviolet light A plurality of tiles are integrally connected by bonding with a curable adhesive. Such a tile sheet can be finished by embedding a mortar in a joint after adhering to the wall surface of the building, resulting in less waste at the construction site, and construction efficiency is greatly improved.

  By the way, since the conventional tile sheet formed by connecting a plurality of tiles by the non-woven fabric described above is one in which adjacent tiles are connected by the non-woven fabric which is relatively soft and easy to stretch, Depending on the tile weight, the vertical and horizontal arrangement of the tiles may be shifted, and the gap between the vertical and horizontal joints may be uneven. In particular, when attaching a tile sheet to a building wall surface, since the upper part of the tile sheet is used for work, the non-woven fabric supporting the weight of each tile is likely to be stretched, and the joint gap tends to be uneven. If the gap between the joints becomes uneven, work for correcting the gap is necessary, and construction work becomes complicated.

  Moreover, since the conventional tile sheet formed by connecting non-woven fabrics connects adjacent tiles with non-woven fabric of a predetermined size, many non-woven fabrics are required. Therefore, in the process of manufacturing the tile sheet, when arranging the non-woven fabric on the plurality of tiles arranged in the vertical and horizontal directions, it takes time and there is a limit in the reduction of the manufacturing cost.

  The present invention is an attempt to solve the above-mentioned problems, and it is possible to maintain the joint space of tiles arranged vertically and horizontally, and a tile sheet which can be easily applied to a building wall, and the tile It aims at providing a manufacturing method of a sheet.

  The present invention is a tile sheet in which a plurality of tiles arranged vertically and horizontally through a joint space are integrally connected, wherein the plurality of arranged tiles are attached to a back surface of each tile by a predetermined adhesive. The flexible thin film-like flexible connection pieces are connected to each other, and the flexible connection pieces are made of a synthetic resin sheet as a base material, and are substantially parallel at predetermined intervals. Adjacent to a plurality of long strip portions provided in a plurality of short connecting portions extending between the long strip portions and provided at predetermined intervals in the longitudinal direction of the long strip portions. And a plurality of openings formed between the short connecting portions, each long band portion connecting a plurality of tiles arranged in two rows along the longitudinal direction or the lateral direction for each row And each short joint portion connects adjacent two rows of tiles connected respectively by the long strip portions. It is a style sheet, which is a shall.

  Here, as the synthetic resin sheet, for example, a sheet of polyethylene, polypropylene, polyamide (nylon), polyethylene terephthalate, polystyrene, polyvinyl chloride, polycarbonate, acrylic resin or the like can be applied. Further, as the adhesive, solvents such as UV curable adhesive, hot melt adhesive, heat curable adhesive, acrylic polymer, vinyl ethyl acetate, ethylene-vinyl acetate copolymer, styrene-bradiene copolymer, acrylonitrile-butadiene copolymer, etc. A mold adhesive or an emulsion adhesive can be applied. In particular, an ultraviolet curable adhesive that contributes to the workability and efficiency in the manufacturing process is suitably used.

  In such a configuration, a plurality of tiles arranged in two rows in the longitudinal direction or the lateral direction are respectively connected by a flexible connection piece based on a synthetic resin sheet, and the flexible connection piece is Since the synthetic resin sheet is relatively difficult to stretch and has relatively high strength, the connected tiles are not easily displaced and a desired joint gap can be maintained. Thus, the tile sheet can be easily and stably attached to the wall of the building while maintaining the joint space. Therefore, the correction work required by the non-uniform joint gap as in the above-described conventional structure is not required in the structure of the present invention, and it is possible to suppress the complicated construction work accompanying the correction work.

  The flexible connecting piece connects a plurality of tiles arranged in a longitudinal direction or a lateral direction by a long strip, and connects two rows of tiles by a short connecting part, and the opening is Since it is formed, in the joint gap between the tiles, there are a region penetrating in the front and back direction and a region not penetrating by the flexible connection piece. And, in the penetration area in the front and back direction in the joint gap, when the tile sheet is attached to the wall of the building, the wall surface is exposed, so when mortar is embedded in the joint gap, the mortar and the wall face Directly bonded. On the other hand, there are a small number of cases where mortar is not embedded in the joint gap, but in this case, although the flexible connecting piece is exposed in a part of the joint gap, the opening is made relatively large. There is also an advantage that the number of exposed parts of the flexible connection piece can be reduced and the flexible connection piece can be made less noticeable.

  In addition, a single flexible connecting piece can connect a plurality of tiles arranged in two rows in the longitudinal direction or in the lateral direction. Therefore, compared with the conventional structure connected by the nonwoven fabric mentioned above, the workability of the manufacture operation which connects this tile can be improved.

  In addition, for the synthetic resin sheet, a sheet whose rear surface has been subjected to a predetermined surface treatment to modify the rear surface to enhance the adhesion to the adhesive is preferably used. Specifically, adhesion to the adhesive may be enhanced by appropriately roughening the back surface of the synthetic resin sheet by a predetermined surface treatment. Incidentally, as the surface treatment to be modified in order to enhance the adhesion as described above, for example, corona discharge treatment is suitably used.

  In the tile sheet of the present invention described above, the flexible connection piece is constituted by a laminated structure in which a non-woven fabric is attached to the back surface of the synthetic resin sheet, and the non-woven fabric is adhered to the tile via an adhesive A configuration is proposed.

  Here, since the non-woven fabric generally has good adhesion to the adhesive as compared to the synthetic resin sheet, according to the present configuration, the flexible connection piece makes the plurality of tiles relatively firm and It can be stably linked.

  In the tile sheet of the present invention described above, the flexible connection piece is constituted by a laminated structure in which paper is attached to the back surface of the synthetic resin sheet, and the paper is adhered to the tile through an adhesive. A configuration is proposed.

  Even in such a configuration, the flexible connection piece can connect the plurality of tiles relatively firmly and stably because the adhesion between the paper and the adhesive is good.

  In the tile sheet of the present invention described above, the flexible connecting piece is formed in a thin film form on the back surface of the synthetic resin sheet in which the adhesion property with the adhesive is higher than that of the synthetic resin sheet. A configuration is proposed in which the back side is adhered to the tile via an adhesive. Here, as the easily adhesive resin, for example, synthetic resins such as urethane resin, polyester, polyamide (nylon) and the like are suitably used. Then, the easy-adhesive resin can be formed into a thin film by attaching a film-like easy-adhesive resin by heat fusion or the like, or applying a liquid easy-adhesive resin.

  In such a configuration, since the easily adhesive resin can relatively adhere well to the tile through the adhesive, the flexible connection piece can connect the plurality of tiles relatively firmly and stably. .

  Further, according to the present invention, there is provided a tile sheet in which a plurality of tiles arranged vertically and horizontally through a joint space are integrally connected, and the plurality of arranged tiles have a predetermined adhesion on the back surface of each tile. Are connected to one another by a long thin film-like flexible connection piece adhered by an adhesive, and the flexible connection piece is made of a resin-impregnated sheet in which a non-woven fabric is impregnated with a synthetic resin, Two long strip portions provided substantially in parallel at intervals, and a plurality of short strips extending between the long strip portions and provided at predetermined intervals in the longitudinal direction of the long strip portions And a plurality of openings formed between adjacent short connecting portions, each long band portion having a plurality of tiles arranged in two rows along the longitudinal direction or the lateral direction. While being connected to each other, each short coupling portion is adjacently connected by each of the long strips. A tile sheet, characterized in that the two rows of tiles between are those respectively connected.

  Here, as a synthetic resin impregnated in the non-woven fabric, for example, polyethylene, polypropylene, polyamide (nylon), polyethylene terephthalate, polystyrene, polyvinyl chloride, polycarbonate, acrylic resin, etc. can be applied. Further, as the adhesive, an ultraviolet-curable adhesive, a hot melt adhesive, a heat-curable adhesive, an acrylic polymer, vinyl ethyl acetate, an ethylene-vinyl acetate copolymer, as in the configuration using the synthetic resin sheet described above Solvent type adhesives and emulsion type adhesives such as styrene-bradiene copolymer and acrylonitrile-butadiene copolymer can be applied. In particular, an ultraviolet curable adhesive that contributes to the workability and efficiency in the manufacturing process is suitably used.

  In this configuration, a plurality of tiles are connected by a flexible connection piece made of a resin-impregnated sheet in which a nonwoven fabric is impregnated with a synthetic resin, and the resin-impregnated sheet is relatively difficult to stretch and has relatively high strength. Since it has, it is hard to shift the connected tile and can maintain a desired joint gap. Thereby, even in the present configuration using a flexible connection piece made of a resin-impregnated sheet, the same function and effect as the configuration using the above-described synthetic resin sheet as a base can be exhibited.

  On the other hand, the present invention is a method of manufacturing a tile sheet in which a plurality of tiles arranged in rows and columns through a joint space are integrally connected, and an array in which a plurality of tiles are arranged in rows and columns through the joint space. A step of arranging a long thin film-like flexible connecting piece on a back surface of the tile via a predetermined adhesive so as to bridge the plurality of arranged tiles; And a bonding step of bonding the flexible connection piece to the back surface of each tile by curing, wherein the flexible connection piece is made of a synthetic resin sheet or impregnated with a synthetic resin.

  According to this manufacturing method, the tile sheet of the present invention described above can be manufactured, and the manufactured tile sheet can exhibit the above-described effects of the present invention. Then, a flexible connection piece is arranged to bridge a plurality of tiles arranged in rows and columns, and the tiles are connected, so that a tile sheet formed by arranging a plurality of tiles via the joint space is obtained. It can be manufactured easily and stably. Thereby, since the manufacturing method of this invention can improve the workability which a manufacturing process requires compared with manufacture of the conventional structure connected by the nonwoven fabric mentioned above, it is possible to reduce manufacturing cost significantly.

It is a reverse view of tile sheet 1 concerning the present invention. It is PP sectional drawing in FIG. It is the L section enlarged view in FIG. FIG. 6 is a plan view of the flexible connection piece 5; It is an explanatory view showing a manufacturing process of tile sheet 1. It is explanatory drawing which shows the arrangement | positioning process which comprises said manufacturing process. It is the elements on larger scale of the longitudinal cross-section of tile sheet 1 of another example.

An embodiment according to the present invention will be described using the attached drawings.
The tile sheet 1 is shown to FIGS. The tile sheet 1 is formed by connecting a plurality of tiles 2 vertically and horizontally arranged through a joint gap 4 by a flexible connection piece 5 and an outermost connection piece 6. The flexible connection piece 5 and the outermost connection piece 6 are adhered to the back surface of each tile 2 by a predetermined adhesive 19.

  Here, in the present embodiment, the tile sheet 1 is formed in a rectangular shape of about 300 × 300 mm by arranging eighteen 45 two-sided hanging tiles 2 in the vertical and horizontal directions. Specifically, each tile 2 has six rows in the horizontal direction, with the long side in the vertical direction and the short side as the horizontal direction, and further, the tile row group 9 in the horizontal direction is parallel to the vertical direction Are arranged in three rows to constitute the tile sheet 1. And each tile 2 is arranged so that joint gap 4 between tiles 2 adjacent to each other in vertical and horizontal directions becomes about 5 mm. In addition, the number and size of the tiles which comprise such a tile sheet 1 are variously changeable, and can be suitably set according to product specification.

  Then, with the plurality of tiles 2 arranged vertically and horizontally in this manner, between the upper row and the middle row of the upper row, the middle row, and the lower row of three row tile groups 9 along the horizontal direction And between the row group of the middle row and the lower row, the above-mentioned flexible connection pieces 5 and 5 are arranged along the lateral direction, respectively. Furthermore, in the upper row and the lower row, the outermost connection pieces 6 and 6 described above are arranged laterally along the upper edge of the upper row and the lower edge of the lower row, respectively. The flexible connection pieces 5 and 5 and the outermost connection pieces 6 and 6 thus arranged are respectively adhered to the back surface of each tile 2 to connect 18 tiles 2 arranged vertically and horizontally, respectively, A tile sheet 1 is formed.

  In addition, the flexible connection piece 5 and the outermost connection piece 6 use a thin film-like synthetic resin sheet 11 as a base material, and laminate the nonwoven fabric 12 to the back surface of the synthetic resin sheet 11. It consists of a structure. Here, the flexible connection piece 5 and the outermost connection piece are formed by bonding the synthetic resin sheet 11 and the non-woven fabric 12 by heat fusion, or by bonding through an adhesive formed in a thin film shape, or the like. It consists of six. In order to form the adhesive in the form of a thin film, it is possible to form the adhesive in the form of a film, apply the adhesive, and so on. As such a synthetic resin sheet 11, a sheet of polyethylene, polypropylene, polyamide (nylon), polyethylene terephthalate, polystyrene, polyvinyl chloride, acrylic resin or the like can be applied. The flexible connection piece 5 and the outermost connection piece 6 are relatively difficult to stretch by the synthetic resin sheet 11 and can exhibit relatively high strength.

  As shown in FIG. 4, the flexible connection piece 5 is provided with two elongated strip portions 15 and 15 substantially parallel to each other at a predetermined constant interval, and the elongated strip portions 15 and 15 are provided. A plurality of short length coupling portions 16 are passed between them and configured. Then, the short connection portions 16 are provided at predetermined intervals in the longitudinal direction, and a plurality of openings 17 are formed between the short connection portions 16, 16 adjacent to each other. Here, the distance between the two long strips 15, 15 is set to a dimension slightly longer than the above-mentioned joint gap 4, and two rows adjacent to each other through the joint gap 4 as shown in FIG. Are arranged on the mutually opposite side edges of the tile row groups 9, 9, respectively. That is, the long strip portion 15 is stretched in the lateral direction on the back surface of each short side edge of the six tiles 2 constituting the tile row group 9. Also, the plurality of short coupling portions 16 are provided at predetermined intervals in the longitudinal direction as described above, and the intervals are slightly longer than the joint gap 4 and slightly shorter than the short side of the tile 2 as the intervals. The short intervals are alternately set. Then, each short coupling portion 16 is disposed so as to cross the joint space between the two adjacent tile row groups 9 and 9. That is, the short joint portion 16 is bridged between the adjacent tiles 2 and 2 via the horizontal joint space 4 of the adjacent two tile row groups 9 and 9, respectively. In this manner, one flexible connecting piece 5 is disposed along the joint gap 4 between two adjacent tile row groups 9, 9, and constitutes twelve tile row groups 9, 9. The 12 tiles 2 are connected to the back of the tile 2 respectively.

  In addition, the outermost connection pieces 6 are formed in an elongated strip shape, and are respectively disposed at the upper edge of the upper tile row group 9 and the lower edge of the lower tile row group 9 as described above. That is, the six tiles 2 constituting the upper row tile group 9 are bridged in the lateral direction on the back surface of each short side edge forming the upper side edge. Similarly, the six tiles 2 constituting the lower row tile group 9 are bridged in the lateral direction on the back surface of each short side edge forming the lower side edge. Thus, as described above, the outermost connection pieces 6, 6 respectively arranged on the upper and lower sides are adhered to the upper row and lower row tile row groups 9, 9, as described above. The tile sheets 1 consisting of 18 tiles 2 connected by 5 are further connected at their upper and lower side edges.

  The adhesive 19 which adheres the flexible connection piece 5 and the outermost connection piece 6 to the back surface of the tile 2 includes an ultraviolet curable adhesive, a hot melt adhesive, a heat curable adhesive, an acrylic polymer, vinyl ethyl acetate, Solvent type adhesives and emulsion type adhesives such as ethylene-vinyl acetate copolymer, styrene-bradiene copolymer, acrylonitrile-butadiene copolymer and the like can be applied. Among them, in consideration of productivity, in the present embodiment, an ultraviolet curable adhesive which is cured from liquid to solid in response to ultraviolet light is used. Since this ultraviolet curable adhesive 19 can apply the general thing which has a photocurable component and a photopolymerization reaction initiator as an essential component, it abbreviate | omits about the detail.

  As described above, the tile sheet 1 of the present embodiment is one in which the plurality of tiles 2 arranged in the vertical and horizontal directions are connected by the flexible connection pieces 5 and 5 and the outermost connection pieces 6 and 6 and integrated. Therefore, in the construction site pasted on the building wall surface, etc., the connected tiles 2 are unlikely to be displaced, and the desired joint gap 4 can be stably maintained. Therefore, the tile sheet 1 can be easily and stably attached to the building wall surface at the construction site. This is because the synthetic resin sheet 11 which is the base material of the flexible connection piece 5 and the outermost connection piece 6 can be prevented from being stretched by the weight of the tile 2 or the like, and sufficient to support the weight of the tile 2 It is due to having strength. Since the joint gap 4 of the tile sheet 1 can be held as described above, the tile sheet 1 according to the present embodiment does not require the correction work required due to the non-uniform joint gap in the conventional configuration described above. It is possible to suppress the complication of construction work accompanying the work.

  Furthermore, the flexible connection piece 5 and the outermost connection piece 6 have a configuration in which the non-woven fabric 12 is attached to the back surface of the synthetic resin sheet 11, and the non-woven fabric 12 is bonded to the back surface of the tile 2 via an adhesive. Thus, the tile 2 can be stably and easily adhered. And, the adhered state can be held for a relatively long time. Non-woven fabric 12 is an adhesive (ultraviolet curable adhesive, hot melt adhesive, heat curable adhesive, acrylic polymer, vinyl ethyl acetate, ethylene-vinyl acetate copolymer, styrene-bradiene copolymer, acrylonitrile-butadiene copolymer, etc. Solvent-based adhesives and emulsion-type adhesives).

  In addition, since the flexible connecting piece 5 has the opening 17 formed between the adjacent short connecting portions 16 and 16, the tile sheet 1 has the tile row groups 9 and 9 in two adjacent rows. In the joint gap 4, there is a region penetrating to the front and back by the opening 17 and a non-penetrating region by the short coupling portion 16. In this penetration area, since the building wall surface is exposed in a state where the tile sheet 1 is attached to the building wall surface, when the mortar or the like is embedded in the joint gap 4, the mortar directly contacts the building wall surface Bonded together. As a result, the bondability between the mortar and the wall of the building can be improved, and the tile sheet 1 can be held more stably in the state of being attached to the wall of the building. On the other hand, in the case where mortar or the like is not embedded in the joint gap 4, the exposed portion (the non-penetration area) of the short joint 16 exposed in the joint gap 4 by the opening 17 is relatively small. The exposed site can be made inconspicuous. When the flexible connection piece and the outermost connection piece have the same color as that of the wall surface of the building, it is possible to make it even less noticeable when the mortar is not embedded in the joint gap 4.

  On the other hand, FIG. 5 shows an example of the process of manufacturing the tile sheet 1 of the present embodiment described above. Here, the manufacturing process mainly includes an arranging step (FIG. 5 (a)) in which a plurality of (18) tiles 2 are arranged vertically and horizontally, flexible connecting pieces 5 and 5 on the back surface of the arranged tiles 2 An arrangement step (FIG. 5 (b)) for arranging the outermost connection pieces 6, 6 and an adhesion step (FIG. 5) for adhering the flexible connection pieces 5, 5 and the outermost connection pieces 6, 6 to the respective tiles 2. And 5 (c).

  In the arranging step, as shown in FIG. 5A, a tile row group 9 in which six tiles 2 are laterally arranged in a row via the joint gap 4 is vertically arrayed via the joint gap 4. The 18 tiles 2 are arranged vertically and horizontally by arranging them in 3 rows, middle row and lower row. Further, in the arranging step, the tile 2 is arranged with the back surface up, and a UV curable adhesive 19 is applied to a predetermined portion of the back surface.

  In the next arrangement step, as shown in FIG. 5B, the joint gap 4 between the upper row and the middle row of tile row groups 9, 9 and the joint gap between the middle row and lower row tile row groups 9, 9 Along 4, flexible connection pieces 5, 5 are arranged on the back of each tile 2 respectively. Thus, in the tile row groups 9 and 10 in the upper row and the middle row, the two long strip portions 15 and 15 of the flexible connection piece 5 form six tiles that form the tile row group 9 in the upper row. The two lower edges and the upper edges of the six tiles 2 constituting the middle row tile group 9 are respectively bridged. Then, a plurality of short coupling portions 16 are respectively bridged between the tiles 2 and 2 facing each other in the vertical direction of the tile row groups 9 and 9 in the upper row and the middle row. Similarly, in the middle row and the lower row of tile row groups 9, 9, the two long strips 15, 15 are respectively lower edges of the six tiles 2 constituting the middle row tile row group 9, and the lower row The respective top edges of the six tiles 2 constituting the tile row group 9 of are respectively bridged. Then, a plurality of short connecting portions 16 are respectively bridged between the tiles 2 and 2 facing each other in the vertical direction of the tile row groups 9 and 9 in the middle row and the lower row. Furthermore, the outermost connection pieces 6, 6 are arranged from the back side of the tile 2 at the upper edge of the upper tile row group 9 and the lower edge of the lower tile row group 9, respectively. Thus, the outermost connection pieces 6 are formed on the upper edges of the six tiles 2 forming the upper row tile group 9 and the lower edges of the six tiles 2 forming the lower row tile group 9. , 6 are bridged respectively. The flexible connection pieces 5 and 5 and the outermost connection pieces 6 and 6 are disposed via an ultraviolet curable adhesive 19 applied to the back surface of the tile 2.

  In the next adhesion step, as shown in FIG. 5C, ultraviolet rays (UV) are irradiated from the back surface side of the tile 2 by an ultraviolet irradiation board (not shown) to cure the ultraviolet curable adhesive 19. Thereby, the flexible connection pieces 5 and 5 and the outermost connection pieces 6 and 6 are adhered to the back surface of the tile 2 and the eighteen tiles 2 are connected. Here, as described above, the flexible connection piece 5 and the outermost connection piece 6 have a laminated structure in which the non-woven fabric 12 is attached to the back surface of the synthetic resin sheet 11 (see FIG. 3). It adheres to the back of the tile 2. Therefore, the non-woven fabric 12 is well adhered to the tiles 2 via the UV curable adhesive 19, and the tiles 2 are stably connected by the flexible connection pieces 5 and the outermost connection pieces 6.

  Further, in the present embodiment, as shown in FIG. 6, in the arrangement step described above, the long thin film connection base material 25 wound around a predetermined core material has a predetermined length dimension and a predetermined width dimension. The flexible connection pieces 5 and 5 and the outermost connection pieces 6 and 6 are formed and disposed on the surface of the tile 2 as described above. Here, the connection base member 25 is in the form of a wide tape, and its width dimension is the sum of two flexible connection pieces 5 and 5 and two outermost connection pieces 6 and 6 in the width direction. It is set to be approximately equal to the dimension. And the dimension of the longitudinal direction of the connection base material 25 is set significantly longer than the transverse dimension of the above-mentioned tile sheet 1, and is wound around a predetermined core material.

  In this arrangement step, as shown in FIG. 6 (a), the connecting base member 25 wound around the core is drawn out, and as shown in FIG. 6 (b), a portion for forming two flexible connecting pieces 5 and 5 Further, the openings 17 are formed in a plurality of rows in a plurality of rows at predetermined intervals in the longitudinal direction. Then, as shown in FIG. 6C, the drawn connection base material 25 is cut at a predetermined length set in accordance with the horizontal dimension of the tile sheet 1, and is further divided along the longitudinal direction. Two flexible connection pieces 5, 5 and two outermost connection pieces 6, 6 are formed. The flexible connection pieces 5 and 5 and the outermost connection pieces 6 and 6 thus formed are arranged on the back surface of the tile 2 arranged in the vertical and horizontal directions as shown in FIG.

  The tile sheet 1 of the present embodiment described above can be easily and stably manufactured by sequentially performing the arranging step, the arranging step, and the bonding step described above. Then, in the disposing step, the step of forming the flexible connecting pieces 5 and 5 and the outermost connecting pieces 6 and 6 from the connecting base material 25 is performed, and a series of flow from the formation to the arrangement is formed. Therefore, the efficiency of these processes can be improved. Therefore, according to the manufacturing process of the present embodiment, the workability required for the manufacturing process can be improved as compared with the case of manufacturing the configuration in which the plurality of non-woven fabrics are arranged, and the cost required for manufacturing can be significantly reduced. It is possible.

  As a configuration of another example of the above-described embodiment, the flexible connection piece and the outermost connection piece can be formed into a laminated structure in which paper is attached to the back surface of the synthetic resin sheet. Even in such a configuration for sticking a paper, as in the case of the non-woven fabric, for example, the paper and the synthetic resin are made by thermally fusing the paper to a synthetic resin sheet or via an adhesive formed in a thin film. It can be formed by bonding with a sheet. As still another configuration, the flexible connecting piece and the outermost connecting piece are formed on the back surface of the synthetic resin sheet, and the adhesion to the ultraviolet curable adhesive is higher than that of the synthetic resin sheet. The resin may be formed into a thin film. Here, as the formation of the easy adhesion resin, a film-like easy adhesion resin may be attached to the back surface of the synthetic resin sheet by heat fusion, or a liquid easy adhesion resin may be synthetic resin. You may make it apply | coat to the back surface of the sheet | seat made. Alternatively, the back surface of the synthetic resin sheet may be subjected to a corona discharge treatment to improve the adhesion of the back surface, and the easily adhesive resin may be formed in a thin film on the back surface. As this easily adhesive resin, for example, synthetic resins such as urethane resin, polyester, polyamide (nylon) and the like are suitably used. The above-mentioned corona discharge treatment is applicable also when pasting a nonwoven fabric or paper on the back of a synthetic resin sheet. Even in the configuration of such another example, the flexible connecting piece and the outermost connecting piece can be stably and easily made of the tile 2 because the adhesiveness with the ultraviolet curable resin is good as in the above-described embodiment. It can be glued to the back. In addition, the structure of such another example is in FIG. 3, in which the flexible connection piece 5 has the above-mentioned paper stuck to the back surface of the synthetic resin sheet 11 instead of the non-woven fabric 12 or the non-woven fabric 12 Instead, the easily adhesive resin is formed into a thin film. That is, the configuration of another example can be described as one in which the nonwoven fabric 12 in FIG. 3 is replaced with the paper 12 or the easily adhesive resin 12.

  Furthermore, as a configuration of another example of the embodiment described above, the flexible connection piece 5 and the outermost connection piece 6 are made of a resin-impregnated sheet 31 in which a non-woven fabric is impregnated with a synthetic resin as shown in FIG. You can also In the configuration of such another example, the resin-impregnated sheet 31 in which the non-woven fabric is reinforced by the synthetic resin can be prevented from being stretched by the weight of the tile 2 or the like and has sufficient strength to support the weight of the tile 2 Thus, the flexible connection piece 5 and the outermost connection piece 6 made of the resin-impregnated sheet 31 can stably maintain the joint gap 4 of each tile 2 connected.
