A fiber material inserted between the base material and the finishing material when a finishing material is attached to the base material,
A fiber material comprising a cotton-like base fabric and a yarn knitted into the cotton-like base fabric, and fibers of the cotton-like base fabric raised.

  In such a case, adjustment can be made to improve the surface accuracy by uniformly weaving the yarn at a portion having a large basis weight or a portion having a small basis weight of the cotton-like base fabric. When the finishing material is bonded to the fiber material adjusted in this way with improved surface accuracy with the adhesive for finishing material sticking, it is possible to obtain appropriate adhesiveness.

  Moreover, it is good also as raising the said fiber by the needle punch method or the stitch bond method.

  In such a case, the fibers of the cotton-like base fabric can be properly raised, and the anchor effect by the fiber material can be further enhanced.

Next, a fiber material tension adhesive application step of applying a fiber material tension adhesive to the surface of the substrate;

A finishing method characterized by comprising:

  In such a case, adjustment can be made to improve the surface accuracy by uniformly weaving the yarn at a portion having a large basis weight or a portion having a small basis weight of the cotton-like base fabric. When the finishing material is bonded to the fiber material adjusted in this way with improved surface accuracy with the adhesive for finishing material sticking, it is possible to obtain appropriate adhesiveness.

  In the fiber material tension adhesive application step, the fiber material tension adhesive may be applied to the surface of the base material in a comb shape.

  In such a case, a valley portion (that is, a void) in which the fiber material tension adhesive does not exist is generated, and the finishing material tension adhesive that has passed through the fiber material and moved to the lower side of the fiber material is The trough will be filled. Therefore, a sufficient amount of the adhesive for finishing material sticking is located on both the front side and the back side of the fiber material, and the connectivity between the fiber material and the adhesive for finishing material sticking is improved. (The degree of integration of both increases.) Therefore, the anchor effect by the fiber material is also increased, and therefore, the finishing material is hardly peeled off in the adhesive for finishing material sticking. Further, even if the finishing material is peeled off, the peeling of the finishing material is appropriately suppressed.

Further, the adhesive for sticking the fiber material is a cement adhesive,

  In such a case, since the fiber material tension adhesive is located on both the front side and the back side of the fiber material, the connectivity between the fiber material and the fiber material tension adhesive is high. (The degree of integration of both increases), and the fiber material is firmly fixed, so that peeling of the finishing material is more appropriately suppressed. In addition, it is possible to suppress the excessive absorption of the moisture of the adhesive for finishing material applied in the adhesive applying process for finishing material by the adhesive for fiber material tensioning, and the adhesive for finishing material tensioning. It becomes possible to suppress the deterioration of the adhesion performance.

It becomes possible to suppress degradation of performance.

=== Regarding the Finishing Method According to the Present Embodiment ===
First, the finishing method according to the present embodiment will be described with reference to FIGS. 1A to 3C. 1A to 1G are explanatory schematic diagrams for explaining a finishing method according to the present embodiment. 2 and 3A to 3C will be described later.

  The finishing method according to the present embodiment is applied to the surface finishing of the outer wall of a building, etc., and is a cement composition (in this embodiment, concrete, ALC panel, extrusion molding cement) as an example of a base material (underlying material). This is a method of attaching a tile 60 as an example of a finishing material to an underlying concrete 10) such as a board. This will be specifically described below.

  First, an operator applies the water absorption adjusting material 20 (a diluted liquid of the water absorption adjusting material) to the surface of the foundation concrete 10 (base material surface water absorption adjusting material application step, see FIG. 1A).

  Here, the water absorption adjusting material 20 plays a role of suppressing excessive absorption of moisture of the polymer cement mortar 30 applied in the next step (fiber material sticking adhesive application step) into the foundation concrete 10. .

  If the polymer cement mortar 30 is applied to the surface of the foundation concrete 10 without applying the water absorption adjusting material 20, the water content of the polymer cement mortar 30 significantly moves to the foundation concrete 10. Therefore, the adhesive performance of the polymer cement mortar 30 is deteriorated by losing moisture.

  Therefore, by applying the water absorption adjusting material 20 before the next step (fiber material sticking adhesive application step), the moisture of the polymer cement mortar 30 is prevented from being excessively absorbed by the base concrete 10, and the polymer cement mortar Thus, the deterioration of the adhesive performance of 30 is prevented.

  Next, the worker applies a fiber material tension adhesive to the surface of the foundation concrete 10 to which the water absorption adjusting material 20 is applied (fiber material tension adhesive application step, see FIG. 1B).

  In the present embodiment, as described above, a cement adhesive (more specifically, polymer cement mortar 30) is applied as the fiber material tension adhesive.

  Further, in the present embodiment, as shown in FIG. 1B, the operator applies the polymer cement mortar 30 in a comb pattern using a comb pattern. Thereby, on the foundation concrete 10 to which the water absorption adjusting material 20 is applied, a crest portion M (a portion where the polymer cement mortar 30 exists) and a trough portion V (a portion where the polymer cement mortar 30 does not exist) Will occur. Note that the pitch of the combs in the present embodiment (the width of the crest portion M and the trough portion V, indicated by the symbol W in FIG. 1B) is 5 mm. The reason why the application method is comb-like will be described later.

  Next, an operator sticks a fiber material to the polymer cement mortar 30 (fiber material sticking step, see FIG. 1C).

  In the present embodiment, as the fiber material (that is, the fiber material inserted between the foundation concrete 10 and the tile 60 when the tile 60 is attached to the foundation concrete 10), A composite fiber material 40 that includes a nonwoven fabric 42 and a yarn 44 knitted with respect to the nonwoven fabric 42 and in which the fibers of the nonwoven fabric 42 are raised is used. Here, the composite fiber material 40 will be described in detail.

  FIG. 2 is a perspective view showing the composite fiber material 40 according to the present embodiment. The composite fiber material 40 according to the present embodiment is obtained by combining a nonwoven fabric 42 and a yarn 44 (more specifically, a polyester filament) by weaving the yarn 44 into the nonwoven fabric 42.

  For both the nonwoven fabric 42 and the yarn 44, various fibers such as vinylon, nylon, polypropylene, polyester, acrylic, and aramid can be used as the material of the fibers used.

Moreover, in this Embodiment, the diameter of the nonwoven fabric 42 is 24 dtex, and a fabric weight is 40 g / m < ² >. The diameter of the yarn 44 is 84 dtex / 36f (single fiber: 2.33 dtexsi), and the basis weight is 20 g / m ² .

  FIG. 3A to FIG. 3C are conceptual diagrams showing a manufacturing procedure of the composite fiber material 40 according to the present embodiment.

  First, an operator prepares the nonwoven fabric 42 as a cotton-like base fabric (see FIG. 3A).

  Next, the operator knits the yarn 44 composed of long fibers into the nonwoven fabric 42 by the stitch bond method so that the yarn 44 becomes a knitted fabric for the nonwoven fabric 42 (see FIG. 3B). That is, the yarn 44 located on the front surface side of the nonwoven fabric 42, the yarn 44 located on the back surface side, and the yarn 44 penetrating from the front surface side (back surface side) to the back surface side (front surface side). So that the yarn 44 is sewn to the nonwoven fabric 42 in three dimensions (in other words, the yarn 44 sandwiches the nonwoven fabric 42). As shown in FIG. 2, in the present embodiment, the yarns 44 are knitted regularly at an equal pitch in the in-plane direction of the nonwoven fabric 42.

  Next, the operator raises the fibers of the nonwoven fabric 42 by the needle punch method or the stitch bond method (see FIG. 3C). As a result, as shown in FIG. 3C, only the fibers on the front surface side are fluffed (raised).

  Returning to the explanation of the finishing method, the explanation is continued. As shown in FIG. 1C, the operator applies the above-mentioned composite fiber material 40 to the polymer cement mortar 30 while impregnating the polymer cement mortar 30 while the polymer cement mortar 30 is uncured. At this time, it is pasted so that the back surface side where no raised fibers are present is the lower side (that is, the base concrete 10 side).

  Next, after curing for a predetermined period and curing the composite fiber material 40 and the polymer cement mortar 30, the operator applies the water absorption adjusting material 20 (diluted liquid of the water absorption adjusting material) to the surface of the composite fiber material 40 (fibers). Material surface water absorption adjusting material application step (see FIG. 1D). As a result, the moisture of the tile mortar 50 applied in the next step (finishing material application adhesive application step) is suppressed from being excessively absorbed by the polymer cement mortar 30, and adhesion of the tile mortar 50 is performed. It becomes possible to suppress degradation of performance.

  Next, the operator applies a cement adhesive for finishing material sticking onto the composite fiber material 40 to which the water absorption adjusting material 20 is applied (finishing material sticking adhesive application step, see FIG. 1E).

  In the present embodiment, as described above, the tiled mortar 50 is applied as the cement adhesive for finishing material application.

  When the tiled mortar 50 is applied onto the composite fiber material 40, the tiled mortar 50 is positioned on the upper side of the composite fiber material 40. However, a part of the tiled mortar 50 is part of the composite fiber material 40. (The water absorption adjusting material 20 also passes) and moves to the lower side of the composite fiber material 40. That is, the tiled mortar 50 is located on both the front side and the back side of the composite fiber material 40.

  Further, as described above, the hardened polymer cement mortar 30 is provided on the lower side of the composite fiber material 40. Since the polymer cement mortar 30 is applied in a comb shape, the valley portion V (that is, the void) ) Exists. Then, the tile attaching mortar 50 moved to the lower side of the composite fiber material 40 enters the valley portion V, and the tile attaching mortar 50 is filled in the valley portion V.

  Next, the operator attaches the tile 60 to the tile attaching mortar 50 (finishing material attaching step, see FIG. 1F).

  And the finishing method is completed by filling the joint mortar 70 in the gap between the tiles 60 for the purpose of preventing rainwater intrusion and deterioration due to ultraviolet rays (a joint mortar filling step, see FIG. 1G).

=== Effectiveness of the fiber material and the like according to the present embodiment ===
As described above, the fiber material according to the present embodiment, that is, the fiber material inserted between the foundation concrete 10 and the tile 60 when the tile 60 is pasted on the foundation concrete 10, is the nonwoven fabric 42 and the nonwoven fabric 42. And a yarn 44 knitted, and a composite fiber material 40 in which fibers of the nonwoven fabric 42 are raised.

  In addition, the finishing method according to the present embodiment includes an adhesive application process for attaching a fiber material to the surface of the foundation concrete 10 and a nonwoven fabric 42 and a yarn 44 knitted into the nonwoven fabric 42. A fiber material sticking step in which the composite fiber material 40 having the fibers of the non-woven fabric 42 raised is attached to the polymer cement mortar 30 and a finishing material sticking adhesive for applying the tile attaching mortar 50 on the composite fiber material 40 An agent application step and a finishing material attaching step of attaching the tile 60 to the tile attaching mortar 50.

  Therefore, it becomes possible to improve the adhesiveness when the tile 60 is bonded.

  The fiber material inserted between the foundation concrete 10 and the tile 60 when the tile 60 is attached to the foundation concrete 10 is already well known. Further, as a finishing method for attaching the tile 60 to the base concrete 10, the polymer cement mortar 30 is applied to the surface of the base concrete 10 and the fiber material is attached, and then the tile attaching mortar 50 is applied and the tile 60 is attached. It was already known how. However, conventionally, the following problems have arisen in the surface finishing (surface finishing formed by such a finishing method) formed using such a fiber material.

  That is, conventionally, a simple nonwoven fabric in which the yarn 44 is not knitted is used as the fiber material. However, when the nonwoven fabric alone is used as the fiber material, there is variation in the basis weight of the fibers constituting the nonwoven fabric. The nonwoven fabric was significantly uneven, and the surface accuracy was not good. Therefore, there has been a problem that proper adhesion cannot be obtained when the tile 60 is adhered to the nonwoven fabric with the tile mortar 50.

  On the other hand, in the present embodiment, as the fiber material, a composite fiber material 40 that includes a nonwoven fabric 42 and a yarn 44 knitted into the nonwoven fabric 42 and has raised fibers of the nonwoven fabric 42 is used. It becomes possible to improve the surface accuracy of the material. That is, the nonwoven fabric 42 can be adjusted to improve the surface accuracy by uniformly weaving the yarn 44 at a portion where the basis weight is large or small. When the tile 60 is bonded to the composite fiber material 40 that has been adjusted in this way and has improved surface accuracy with the tile-attaching mortar 50, it is possible to obtain appropriate adhesiveness.

  In the present embodiment, the fibers of the nonwoven fabric 42 of the composite fiber material 40 are raised by the needle punch method or the stitch bond method. Therefore, it becomes possible to raise the fiber of the nonwoven fabric 42 appropriately, and the anchor effect by the composite fiber material 40 can be further enhanced.

  In the present embodiment, the adhesive for sticking the fiber material is a cement adhesive (specifically, polymer cement mortar 30). And it decided to apply | coat the water absorption adjusting material 20 to the surface of the composite fiber material 40 before the adhesive agent application process for finishing material sticking.

  Therefore, as described above, the moisture of the tile mortar 50 applied in the finishing material application adhesive application step is suppressed from being excessively absorbed by the polymer cement mortar 30, and the adhesive performance of the tile mortar 50 is deteriorated. Can be suppressed.

  In the present embodiment, the base material (base material) is a cement composition (specifically, the base concrete 10). And it decided to apply | coat the water absorption adjusting material 20 to the surface of a base material (base material) before the adhesive material application process for fiber material sticking.

  Therefore, as described above, excessive absorption of moisture of the polymer cement mortar 30 applied in the fiber material tensioning adhesive application step into the ground concrete 10 is suppressed, and deterioration of the adhesive performance of the polymer cement mortar 30 is prevented. It becomes possible to suppress.

=== Other Embodiments ===
The above embodiments are for facilitating the understanding of the present invention, and are not intended to limit the present invention. The present invention can be changed and improved without departing from the gist thereof, and it is needless to say that the present invention includes equivalents thereof. In particular, the embodiments described below are also included in the present invention.

  In the above embodiment, the polymer cement mortar 30 is applied in a comb shape on the surface of the foundation concrete 10 in the fiber material tensioning adhesive application step. However, the present invention is not limited to this. For example, the polymer cement mortar 30 may be uniformly applied to the surface of the foundation concrete 10.

  However, when the polymer cement mortar 30 is applied in the shape of a comb on the surface of the foundation concrete 10, as described above, a valley portion V (that is, a void) where the polymer cement mortar 30 does not exist is generated, and the composite fiber material 40 is formed. The tiling mortar 50 that has passed through and moved to the lower side of the composite fiber material 40 is filled in the valley portion V. Therefore, a sufficient amount of the tiled mortar 50 is located on both the front side and the back side of the composite fiber material 40, and the connectivity between the composite fiber material 40 and the tiled mortar 50 is increased (both). The degree of integration becomes higher). Therefore, the anchor effect by the composite fiber material 40 is also increased, and therefore, the tile 60 is hardly peeled off in the tile attaching mortar 50. Further, even if the tile 60 is peeled off, the peeling of the tile 60 is appropriately suppressed. In this respect, the above embodiment is more desirable.

  Further, in the above embodiment, the adhesive for sticking the fiber material is a cement adhesive (specifically, polymer cement mortar 30), but is not limited to this. For example, Organic adhesives may also be used.

  When the adhesive for sticking the fiber material is a cement adhesive, a part of the cement adhesive passes through the composite fiber material 40 (and the water absorption adjusting material 20 also passes), and the composite fiber material 40 It can be expected to move upward (on the other hand, in the case of an organic adhesive, such an action cannot be expected. Note that such a phenomenon is not shown in FIGS. 1A to 1G). In such a case, since the adhesive for fiber material tension is located on both the front side and the back side of the composite fiber material 40, the composite fiber material 40 and the fiber material tension The adhesiveness of the adhesive is increased (the degree of integration of both is increased), and the composite fiber material 40 is firmly fixed, so that the peeling of the tile 60 is further appropriately suppressed. In this respect, the above embodiment is more desirable.

  In the above embodiment, the base material (underlying material) is a cement composition (specifically, underlaying concrete 10), but is not limited to this. It may be a board.

  Moreover, about the diameter of the nonwoven fabric 42, the value larger than 1 dtex and smaller than 500 dtex is preferable. If it is not larger than 1 dtex, the pulling resistance of the fibers entangled with the tiled mortar 50 cannot be secured, and if it exceeds 500 dtex, the fiber diameter is too thick, the fibers do not get entangled, and the fabric weight tends to be uneven. .

Also, the basis weight of the nonwoven fabric 42 is greater 600 g / m ² smaller value than 10 g / m ² is preferred. If it is not larger than 10 g / m ² , the surface shape is not formed as a nonwoven fabric, and if it exceeds 600 g / m ² , the basis weight is too fine and the tiled mortar 50 is not impregnated.

  The diameter of the yarn 44 is preferably a value larger than 10 dtex and smaller than 500 dtex. If it is not larger than 10 dtex, weaving cannot be performed, and if it exceeds 500 dtex, the fiber diameter is too large, the fibers do not get tangled, and the basis weight tends to be uneven.

Also, the basis weight of the yarn 44, large 50 g / m ² smaller value than 1 g / m ² is preferred. If not greater than 1 g / m ^2, can not weave the yarn 44 to the three-dimensional shape, if it exceeds 50 g / m ^2, and knit stitch is too fine, the tiles stuck mortar 50 because no impregnation.
