Description

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

  Conventionally, for the purpose of improving the workability of exterior tiles, tile sheets formed by connecting a plurality of tiles in a sheet shape have been used. In such a tile sheet, each tile is arranged vertically and horizontally through joint gaps, and it adheres to the wall of the building via adhesive mortar and embeds the mortar in the joint gap, so that multiple tiles can be pasted at once. Can do. Conventionally, as this type of tile sheet, a sheet in which tiles are connected by a paper pasted on the tile surface with starch paste has been provided. However, in the conventional tile sheet, after the tile sheet is bonded to the building wall, water is applied to the surface of the tile to peel off the paper, and the peeled paper becomes a large amount of waste. Also, such tile sheets can be easily peeled off from paper if left in high humidity conditions or wet with rain, etc., so they are packed in cardboard cartons and brought into the field to avoid rain. After use, not only the paper affixed to the tiles but also the corrugated cardboard cartons used for packaging are generated in large quantities as garbage. For this reason, such a tile sheet has been strongly demanded from the field for improvement.

  Therefore, a tile sheet has been proposed in which a plurality of tiles arranged vertically and horizontally are connected with a nonwoven fabric via an ultraviolet curable adhesive (for example, Patent Document 1). Specifically, a plurality of tiles are arranged vertically and horizontally through the joint gap, and a plurality of non-woven fabrics are arranged on the back surface of the tile so as to cross the joint gap, and the back surface of each tile and the non-woven fabric are bonded to each other with ultraviolet rays. A plurality of tiles are integrally connected by bonding with a curable adhesive. Such a tile sheet can be finished by embedding mortar in the joint after being bonded to the wall surface of the building, and there is little waste at the construction site, and the workability is greatly improved.

  By the way, since the tile sheet formed by connecting a plurality of tiles with a nonwoven fabric as described above is connected with adjacent tiles by a nonwoven fabric that is relatively flexible and easy to stretch, during transportation and construction, Depending on the tile weight, the vertical and horizontal arrangement of the tiles may be shifted, and the vertical and horizontal joint gaps may become non-uniform. In particular, when a tile sheet is attached to a building wall, the work is carried with the upper part of the tile sheet, so that the nonwoven fabric that supports the weight of each tile is likely to be stretched, and the joint gap is likely to be uneven. And if the joint gap becomes non-uniform, a work for correcting this is necessary, so that the construction work becomes complicated.

  Moreover, since the conventional tile sheet | seat connected with a nonwoven fabric connects adjacent tiles with the nonwoven fabric of predetermined size, many this nonwoven fabric is required. Therefore, in the process of manufacturing a tile sheet, it takes time and effort to place a nonwoven fabric on a plurality of tiles arranged vertically and horizontally, and there is a limit to the reduction in manufacturing cost.

  The present invention is an attempt to solve the above-described problems, and a tile sheet that can maintain a joint gap between tiles arranged vertically and horizontally and can be easily applied to a building wall, and the tile. It aims at providing the manufacturing method of a sheet | seat.

  The present invention is a tile sheet in which a plurality of tiles arranged vertically and horizontally are integrally connected via joint gaps, and the plurality of tiles arranged are attached to the back surface of each tile by a predetermined adhesive. The flexible connecting pieces are connected to each other by bonded thin thin film-like flexible connecting pieces, and the flexible connecting pieces are made of a synthetic resin sheet as a base material and are substantially parallel at a predetermined interval. Adjacent to the two long strips provided on the two strips, and a plurality of short coupled portions provided between the long strips and provided at predetermined intervals in the longitudinal direction of the long strips A plurality of openings formed between the short coupled portions, and each long belt portion connects a plurality of tiles arranged in two rows along the vertical direction or the horizontal direction for each row, respectively. In addition, each short coupled portion connects two adjacent tiles that are respectively connected by the respective 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. In addition, as the adhesive, solvents such as 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. A mold adhesive or an emulsion adhesive can be applied. In particular, an ultraviolet curable adhesive that contributes to workability and efficiency in the manufacturing process is preferably used.

  In such a configuration, a plurality of tiles arranged in two rows in the vertical direction or the horizontal direction are respectively connected by flexible connecting pieces using a synthetic resin sheet as a base material. Since the synthetic resin sheet is relatively difficult to stretch and has a relatively high strength, the connected tiles are not easily displaced, and a desired joint gap can be maintained. Accordingly, the tile sheet can be easily and stably attached to the building wall surface while maintaining the joint gap. Therefore, the correction work required when the joint gap becomes non-uniform as in the conventional structure described above is not required in the structure of the present invention, and the construction work associated with the correction work can be prevented from becoming complicated.

  The flexible connecting piece connects a plurality of tiles arranged in the vertical direction or the horizontal direction by a long belt portion, and connects two rows of tiles by a short coupling portion, and further has an opening. Since it is formed, the joint gap between the tiles includes a region penetrating in the front and back direction and a region not penetrating by the flexible connecting piece. And, in the penetration area in the front and back direction in the joint gap, the wall surface is exposed with the tile sheet attached to the wall surface of the building, so that when the mortar is embedded in the joint gap, the mortar and the wall face are exposed. Directly joined. On the other hand, there is a small number of cases where mortar is not embedded in the joint gap. In this case, although the flexible connecting piece is exposed in a part of the joint gap, the opening is formed to be relatively large. There is also an advantage that the exposed portion of the flexible connecting piece can be reduced and the flexible connecting piece can be made inconspicuous.

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

  In addition, as the synthetic resin sheet, a sheet obtained by performing a predetermined surface treatment on the back surface and modifying the back surface to improve the adhesiveness with the adhesive is preferably used. Specifically, the adhesiveness with the adhesive may be improved by appropriately roughening the back surface of the synthetic resin sheet by a predetermined surface treatment. For example, a corona discharge treatment is preferably used as the surface treatment that is modified in order to improve the adhesion.

  In the tile sheet of the present invention described above, the flexible connecting piece is configured by a laminated structure in which a nonwoven fabric is pasted on the back surface of a synthetic resin sheet, and the nonwoven fabric is bonded to the tile via an adhesive. A configuration is proposed.

  Here, since non-woven fabrics generally have better adhesiveness with adhesives than synthetic resin sheets, according to this configuration, a plurality of tiles are relatively firmly secured by flexible connecting pieces. It can be connected stably.

  In the tile sheet of the present invention described above, the flexible connecting piece is configured by a laminated structure in which paper is pasted on the back surface of the synthetic resin sheet, and the paper is bonded to the tile via an adhesive. A configuration is proposed.

  Even in such a configuration, since the adhesiveness between the paper and the adhesive is good, a plurality of tiles can be connected relatively firmly and stably by the flexible connecting piece.

  In the tile sheet of the present invention described above, the flexible connecting piece is formed of a highly adhesive resin having a higher adhesiveness with the adhesive than the synthetic resin sheet in the form of a thin film on the back surface of the synthetic resin sheet. A configuration is proposed in which the back side is bonded to the tile via an adhesive. Here, as the easily adhesive resin, for example, a synthetic resin such as urethane resin, polyester, polyamide (nylon) is preferably used. The easy-adhesive resin can be formed into a thin film by sticking a film-like easy-adhesive resin by thermal fusion or applying a liquid easy-adhesive resin.

  In such a configuration, the easily adhesive resin can be bonded relatively well to the tile via an adhesive, and therefore a plurality of tiles can be connected relatively firmly and stably by the flexible connecting piece. .

  Further, the present invention is a tile sheet in which a plurality of tiles arranged vertically and horizontally are integrally connected via joint gaps, and the plurality of arranged tiles are bonded to a back surface of each tile with a predetermined adhesion. Are connected to each other by a long thin film-like flexible connecting piece bonded by an agent, and the flexible connecting piece is made of a resin-impregnated sheet in which a nonwoven fabric is impregnated with a synthetic resin, Two long strips provided approximately parallel to each other at intervals, and a plurality of short strips provided between the long strips and provided at predetermined intervals in the longitudinal direction of the long strips A plurality of tiles arranged in two rows along the longitudinal direction or the lateral direction, each of which includes a plurality of openings formed between adjacent formed short portions and a plurality of openings. Adjacent to each other, and each short coupled portion is connected to each other by the long strip portion. A tile sheet, characterized in that the two rows of tiles between are those respectively connected.

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

  In such a configuration, a plurality of tiles are connected by a flexible connecting piece made of a resin-impregnated sheet in which a nonwoven fabric is impregnated with a synthetic resin. The resin-impregnated sheet is relatively difficult to stretch and has a relatively high strength. Thus, the connected tiles are difficult to shift, and a desired joint gap can be maintained. Thereby, even if it is in this structure using the flexible connection piece which consists of a resin impregnation sheet | seat, there can exist an effect similar to the structure which uses the synthetic resin sheet | seat as a base material mentioned above.

  On the other hand, the present invention is a tile sheet manufacturing method in which a plurality of tiles arranged vertically and horizontally through a joint gap are integrally connected, and the tile is arranged vertically and horizontally through a joint gap. A step of arranging a long thin film-like flexible connecting piece on a back surface of the tile with a predetermined adhesive so as to bridge the plurality of tiles arranged, and the adhesive A step of curing and adhering the flexible connecting pieces to the back surface of each tile, respectively. The flexible connecting pieces are made of a synthetic resin sheet or a nonwoven fabric impregnated with a synthetic resin. Two long strip portions provided in parallel at a predetermined interval, and are inserted between the long strip portions, and are predetermined in the longitudinal direction of the long strip portion. Between a plurality of short coupled portions provided at intervals and an adjacent short coupled portion A plurality of openings formed, and in the arranging step, each long belt portion is arranged so as to bridge a plurality of tiles arranged in two rows along the vertical direction or the horizontal direction. In addition, the tile sheet manufacturing method is characterized in that each short coupled portion is arranged so as to bridge two adjacent tiles spanned by each long belt portion.

  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, the flexible connecting pieces are arranged so as to bridge a plurality of tiles arranged vertically and horizontally, and the tiles are connected, so that a tile sheet in which a plurality of tiles are arranged through joint gaps, It can be manufactured easily and stably. Thereby, since the manufacturing method of this invention can improve the workability | operativity which a manufacturing process requires compared with manufacture of the conventional structure connected with the nonwoven fabric mentioned above, it can reduce manufacturing cost significantly.

  In the method for manufacturing a tile sheet of the present invention described above, a long thin film in which outermost connection pieces on both sides for connecting a plurality of tiles at both side edges of the tile sheet and a flexible connection piece are integrated. A plurality of openings are formed at the formation site of the flexible connection piece, and are divided along the longitudinal direction, and the flexible connection piece and the outermost connection piece formed by the division; In the arranging step, a manufacturing method is proposed in which a plurality of tiles arranged in the vertical and horizontal directions are arranged via an adhesive.

  According to this manufacturing method, in the tile sheet manufacturing process, the connection base material is divided to form the flexible connection piece and the outermost connection piece, and the flexible connection is made to a plurality of tiles arranged vertically and horizontally. A series of flows until the pieces and the outermost connecting pieces are arranged can be performed more easily and stably. And the workability | operativity of such a process can be improved further. Therefore, the above-described effect of the present invention for reducing the manufacturing cost is further improved.

  As described above, the tile sheet of the present invention connects a plurality of tiles arranged vertically and horizontally by a flexible connecting piece having two long strip portions, a plurality of short coupled portions, and a plurality of openings. Since the joints between the tiles can be stably maintained by the flexible connecting piece based on the synthetic resin sheet, it is easy to apply the work to the building wall surface. It can be implemented stably. Moreover, even if it is the structure using the movable connection piece which consists of a resin impregnation sheet | seat which the synthetic resin impregnated the nonwoven fabric, there exists the same effect.

  On the other hand, according to the tile sheet manufacturing method of the present invention, the above-described tile sheet of the present invention can be manufactured easily and stably.

FIG. It is explanatory drawing which shows the manufacturing process of the tile sheet. 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 the tile sheet 1 of another example.

Embodiments according to the present invention will be described with reference to the accompanying drawings.
1-3, the tile sheet 1 is shown. The tile sheet 1 is formed by connecting a plurality of tiles 2 arranged vertically and horizontally via joint gaps 4 by a flexible connecting piece 5 and an outermost connecting piece 6. The flexible connecting piece 5 and the outermost connecting piece 6 are bonded to the back surface of each tile 2 with a predetermined adhesive 19.

  Here, in this embodiment, the tile sheet 1 is formed in a rectangular shape of about 300 × 300 mm by arranging 18 45 double-cage tiles 2 vertically and horizontally. More specifically, each tile 2 is arranged in six rows in a row in the horizontal direction with the long side in the vertical direction and the short side in the horizontal direction, and the tile row group 9 in the horizontal row is parallel to the vertical direction. The tile sheet 1 is configured in three rows. The tiles 2 are arranged so that the joint gap 4 between adjacent tiles 2 in the vertical and horizontal directions is about 5 mm. Note that the number and size of tiles constituting such a tile sheet 1 can be variously changed, and can be appropriately set according to product specifications.

  Then, in a state where a plurality of tiles 2 are arranged vertically and horizontally in this manner, the tile row group 9 of the upper row, the middle row, and the lower row along the horizontal direction between the row groups of the upper row and the middle row. The flexible connecting pieces 5 and 5 are arranged along the lateral direction between the middle row and the lower row. Further, in the upper row and the lower row, the outermost connection pieces 6 and 6 are arranged along the lateral direction on the upper edge of the upper row and the lower edge of the lower row, respectively. The flexible connecting pieces 5 and 5 and the outermost connecting pieces 6 and 6 arranged in this way are bonded to the back surface of each tile 2, so that the 18 tiles 2 arranged vertically and horizontally are respectively connected. A tile sheet 1 is formed.

  The flexible connecting piece 5 and the outermost connecting piece 6 are based on a thin-film synthetic resin sheet 11, and are laminated with a nonwoven fabric 12 attached to the back surface of the synthetic resin sheet 11. Consists of structure. Here, the synthetic resin sheet 11 and the non-woven fabric 12 are bonded by thermal fusion or bonded through an adhesive formed in a thin film shape, etc., so that the flexible connection piece 5 or the outermost connection piece is obtained. 6 is constituted. For forming the adhesive in a thin film, it is possible to apply the adhesive in the form of a film or by applying the adhesive. 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. And the flexible connection piece 5 and the outermost connection piece 6 are comparatively hard to extend | stretch with the synthetic resin sheet | seat 11, and can exhibit comparatively high intensity | strength.

  As shown in FIG. 4, the flexible connecting piece 5 is provided with two elongated strips 15 and 15 that are substantially parallel to each other at a predetermined constant interval. A plurality of short coupled portions 16 are interposed therebetween. And the short continuous part 16 is provided in the longitudinal direction at predetermined intervals, and the several opening part 17 is formed between the short continuous parts 16 and 16 adjacent to each other. Here, the distance between the two long strips 15 and 15 is set to be slightly longer than the joint gap 4, and two rows adjacent to each other through the joint gap 4 as shown in FIG. The tile row groups 9 and 9 are arranged on the side edges facing each other. That is, the long belt portion 15 is bridged along the lateral direction on the back surface of each short side edge of the six tiles 2 constituting the tile row group 9. The plurality of short coupled portions 16 are provided at predetermined intervals in the longitudinal direction as described above. As the intervals, the intervals are slightly longer than the joint gap 4 and slightly shorter than the short sides of the tile 2. Short intervals are alternately set. Each short-length coupled portion 16 is arranged so as to cross the joint gap between the two adjacent tile rows 9 and 9. That is, the short coupled portion 16 is bridged between the adjacent tiles 2 and 2 through the joint spacing 4 in the horizontal direction of the adjacent two tile row groups 9 and 9. In this way, one flexible connecting piece 5 is arranged along the joint gap 4 between two adjacent tile row groups 9, 9, and constitutes 12 tile row groups 9, 9. The twelve tiles 2 are connected to the back surfaces of the tiles 2.

  Further, the outermost connection piece 6 is formed in an elongated strip shape, and is disposed on 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 tile row group 9 are bridged along the lateral direction on the back surface of each short side edge forming the upper edge. Similarly, the six tiles 2 constituting the lower tile row group 9 are spanned along the lateral direction on the back surface of each short side edge forming the lower side edge. As described above, the outermost connecting pieces 6 and 6 arranged on both the upper and lower sides are bonded to the tile row groups 9 and 9 in the upper row and the lower row, respectively. The tile sheets 1 composed of 18 tiles 2 connected by 5 are further connected at the upper and lower side edges.

  Examples of the adhesive 19 for bonding the flexible connecting piece 5 and the outermost connecting piece 6 to the back surface of the tile 2 include an ultraviolet curable adhesive, a hot melt adhesive, a heat curable adhesive, an acrylic polymer, vinyl ethyl acetate, Solvent adhesives such as ethylene-vinyl acetate copolymers, styrene-bradiene copolymers, acrylonitrile-butadiene copolymers, and emulsion adhesives can be applied. Among these, in consideration of productivity, in this embodiment, an ultraviolet curable adhesive that is cured from a liquid to a solid in response to ultraviolet rays is used. As the ultraviolet curable adhesive 19, since a general adhesive having a photocurable component and a photopolymerization reaction initiator as essential components can be applied, the details thereof are omitted.

  As described above, the tile sheet 1 of the present embodiment is obtained by integrating a plurality of tiles 2 arranged vertically and horizontally by connecting the flexible connecting pieces 5 and 5 and the outermost connecting pieces 6 and 6. Therefore, the tiles 2 connected to each other are difficult to shift at a construction site to be attached to the building wall surface, 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 that is the base material of the flexible connecting piece 5 and the outermost connecting piece 6 can be prevented from stretching due to the weight of the tile 2 and the like, and sufficient to support the weight of the tile 2. Due to having strength. Since the joint gap 4 of the tile sheet 1 can be held in this manner, the tile sheet 1 of the present embodiment does not require the correction work required due to the joint gap being non-uniform in the conventional configuration described above. Complicated construction work associated with work can be suppressed.

  Furthermore, the flexible connecting piece 5 and the outermost connecting piece 6 have a configuration in which a 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. Therefore, it can be bonded to the tile 2 stably and easily. And the state which adhere | attached can be hold | maintained over a comparatively long term. This is because the nonwoven fabric 12 is an adhesive (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. (Solvent type adhesive and emulsion type adhesive).

  Further, since the flexible connecting piece 5 has an opening 17 formed between the adjacent short coupled portions 16 and 16, the tile sheet 1 includes two adjacent tile row groups 9 and 9. In the joint gap 4, there are a region penetrating front and back by the opening 17 and a non-penetrating region by the short coupled portion 16. In this penetrating region, the wall surface of the building is exposed with the tile sheet 1 attached to the wall surface of the building. Therefore, when mortar or the like is embedded in the joint gap 4, the mortar directly contacts the wall surface of the building. Are joined together. Thereby, the bondability between the mortar and the building wall surface can be improved, and the tile sheet 1 can be held more stably in a state where the tile sheet 1 is attached to the building wall surface. 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-penetrating region) of the short coupled portion 16 exposed in the joint gap 4 by the opening 17 is relatively small. The exposed part can be made inconspicuous. In addition, when the mortar is not embedded in the joint gap 4 by making the flexible connecting piece and the outermost connecting piece have the same color as the wall surface of the building, it can be made more inconspicuous.

  On the other hand, FIG. 5 shows an example of a process for manufacturing the tile sheet 1 of the above-described embodiment. Here, the manufacturing process mainly includes an arranging step (FIG. 5A) in which a plurality (18) of tiles 2 are arranged vertically and horizontally, and flexible connecting pieces 5, 5 and 5 on the back surface of the arranged tiles 2. Arrangement step for arranging the outermost connection pieces 6 and 6 (FIG. 5B), and bonding step for bonding the flexible connection pieces 5 and 5 and the outermost connection pieces 6 and 6 to each tile 2 (FIG. 5 (c)).

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

  In the next arrangement step, as shown in FIG. 5 (b), the joint gap 4 between the tile row groups 9 and 9 in the upper row and the middle row and the joint gap between the tile row groups 9 and 9 in the middle row and the lower row. 4, flexible connecting pieces 5 and 5 are arranged on the back surface of each tile 2, respectively. Thereby, in the tile row groups 9 and 9 of the upper row and the middle row, the two long strip portions 15 and 15 of the flexible connecting piece 5 are the six tiles constituting the upper row of tile rows 9. 2 and the upper edge of each of the six tiles 2 constituting the tile row group 9 in the middle row. Then, a plurality of short coupled portions 16 are spanned between the tiles 2 and 2 facing each other in the vertical direction of the tile row groups 9 and 9 of the upper row and the middle row. Similarly, also in the tile row groups 9 and 9 of the middle row and the lower row, the two long strip portions 15 and 15 are arranged on the lower edge of each of the six tiles 2 constituting the tile row group 9 of the middle row and the lower row. Are spanned to the respective upper edges of the six tiles 2 constituting the tile row group 9. Then, a plurality of short coupled portions 16 are spanned between the tiles 2 and 2 facing each other in the vertical direction in the tile row groups 9 and 9 of the middle row and the lower row, respectively. Further, the outermost connection pieces 6 and 6 are arranged on the upper edge of the upper tile row group 9 and the lower edge of the lower tile row group 9 from the back surface side of the tile 2, respectively. As a result, the outermost connecting piece 6 is connected to each upper side edge of the six tiles 2 constituting the upper tile row group 9 and each lower side edge of the six tiles 2 constituting the lower tile row group 9. , 6 are overlaid. The flexible connecting pieces 5 and 5 and the outermost connecting pieces 6 and 6 are arranged via an ultraviolet curable adhesive 19 applied to the back surface of the tile 2.

  In the next bonding step, as shown in FIG. 5C, ultraviolet rays (UV) are irradiated from the back side of the tile 2 by an ultraviolet irradiation board (not shown) to cure the ultraviolet curable adhesive 19. Accordingly, the flexible connecting pieces 5 and 5 and the outermost connecting pieces 6 and 6 are bonded to the back surface of the tile 2 to connect the 18 tiles 2. Here, as described above, the flexible connecting piece 5 and the outermost connecting piece 6 have a laminated structure in which the nonwoven fabric 12 is pasted on the back surface of the synthetic resin sheet 11 (see FIG. 3). It adheres to the back surface of the tile 2. Therefore, the nonwoven fabric 12 is well bonded to the tile 2 via the ultraviolet curable adhesive 19, and each tile 2 is stably connected by the flexible connecting piece 5 and the outermost connecting piece 6.

  Further, in this embodiment, in the arrangement step described above, as shown in FIG. 6, the long thin film-like connection base material 25 wound around a predetermined core material has a predetermined length dimension and a predetermined width dimension. The flexible connecting pieces 5 and 5 and the outermost connecting pieces 6 and 6 are formed and arranged on the paper surface of the tile 2 as described above. Here, the connection base member 25 has a wide tape shape, and the width dimension is obtained by adding the two flexible connection pieces 5 and 5 and the two outermost connection pieces 6 and 6 in the width direction. It is set to be approximately equal to the dimension. And the connection base material 25 is set so that the dimension of the longitudinal direction is remarkably longer than the horizontal dimension of the tile sheet 1 described above, and is wound around a predetermined core material.

  In this arrangement step, the connection base material 25 wound around the core material is pulled out as shown in FIG. 6A, and the two flexible connection pieces 5 and 5 are formed as shown in FIG. 6B. In addition, a plurality of openings 17 are formed in two rows at predetermined intervals in the longitudinal direction. Then, as shown in FIG. 6C, the drawn connection base material 25 is cut with a predetermined length dimension set in accordance with the horizontal dimension of the tile sheet 1, and further divided along the longitudinal direction. Two flexible connecting pieces 5 and 5 and two outermost connecting pieces 6 and 6 are formed. The flexible connecting pieces 5 and 5 and the outermost connecting pieces 6 and 6 formed in this way are arranged on the back surface of the tiles 2 arranged vertically and horizontally as shown in FIG.

  By sequentially performing the above-described arrangement step, arrangement step, and adhesion step, the above-described tile sheet 1 of the present embodiment can be manufactured easily and stably. And in the arranging 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 carried out, and a series of flow from the forming to the arranging is made. Therefore, the efficiency of these processes can be measured. 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 described above are arranged, and thus the cost required for manufacturing is greatly reduced. It is possible.

  As a configuration of another example of the above-described embodiment, the flexible connection piece and the outermost connection piece may have a laminated structure in which paper is attached to the back surface of the synthetic resin sheet. Even in such a configuration where the paper is affixed, as in the case of the nonwoven fabric, for example, the paper and the synthetic resin may be made by heat-sealing the synthetic resin sheet or an adhesive formed in a thin film shape. It can be formed by bonding the sheet. Furthermore, as another example, the flexible connecting piece and the outermost connecting piece are easily adhered to the back surface of the synthetic resin sheet, which has higher adhesion to the ultraviolet curable adhesive than the synthetic resin sheet. The resin may be formed into a thin film. Here, as the formation of the easy-adhesive resin, a film-like easy-adhesive resin may be attached to the back surface of the synthetic resin sheet by thermal fusion, or a liquid easy-adhesive resin may be used as the synthetic resin. You may make it apply | coat to the back surface of a sheet made. Alternatively, the back surface of the synthetic resin sheet may be subjected to corona discharge treatment to improve the adhesiveness of the back surface, and the easily adhesive resin may be formed in a thin film shape on the back surface. As this easily adhesive resin, for example, a synthetic resin such as urethane resin, polyester, polyamide (nylon) is preferably used. In addition, the said corona discharge process is applicable also when sticking a nonwoven fabric and paper on the back surface of a synthetic resin sheet. Even in the configuration of such another example, the adhesiveness with the ultraviolet curable resin is good as in the above-described embodiment, so that the flexible connecting piece and the outermost connecting piece can be stably and easily attached to the tile 2. Can be glued to the back side. In addition, the configuration of such another example is shown in FIG. 3, in which the flexible connecting piece 5 has the above-mentioned paper pasted on the back surface of the synthetic resin sheet 11 instead of the nonwoven fabric 12, or the nonwoven fabric 12. Instead, an easy-adhesive resin is formed into a thin film. That is, the configuration of another example can be described as a case where the nonwoven fabric 12 in FIG. 3 is replaced with the paper 12 or the easily adhesive resin 12.

  Furthermore, as another configuration of the above-described embodiment, the flexible connecting piece 5 and the outermost connecting piece 6 are made of a resin-impregnated sheet 31 in which a nonwoven fabric is impregnated with a synthetic resin as shown in FIG. You can also In such another configuration, the resin-impregnated sheet 31 in which the nonwoven fabric is reinforced with synthetic resin can be prevented from stretching due to the weight of the tile 2 and the like, and has sufficient strength to support the weight of the tile 2. Therefore, the flexible connecting piece 5 and the outermost connecting piece 6 made of the resin-impregnated sheet 31 can stably keep the joint gaps 4 of the connected tiles 2.
