Description

  The present invention relates to a pavement method, and more particularly to a pavement method focusing on a coated floor using resin mortar.

  2. Description of the Related Art Conventionally, a coated floor method using a synthetic resin is widely known as a pavement method in a road environment in which landscape is important. The painted floor method is a method of finishing the pavement surface by applying resin mortar with a synthetic resin as a binder. The so-called `` wet method '' is to apply a liquid resin mortar at the construction site and dry it to finish the floor surface. "It is known as a" dry method "in factories, etc., where floor materials that have been pre-coated with resin mortar as unit members are transported to the construction site, and floors are formed by spreading the unit members. Yes.

  By the way, various patterns and patterns are often drawn on the pavement surface that places importance on the landscape. In particular, a grid-like joint pattern is widely applied as a natural cobblestone-like texture. In order to realize a grid-like joint pattern in the so-called “wet method”, for example, a formwork or a straight rod-like joint member formed in a grid-like joint pattern in advance is used. A method is adopted in which a resin mortar is applied to the construction surface and a resin mortar is applied thereon, and after the resin mortar is dried, a mold or the like is removed. By using such a method, since the resin mortar is applied only to a portion without the mold, it is possible to form a pavement surface having a joint pattern having the same shape as the mold.

  However, the above-described wet method has a problem that the quality of the finished floor surface is greatly affected by the climatic conditions of the construction site (especially outdoors) and the temperature and humidity conditions. Furthermore, it is necessary to limit the intrusion of pedestrians on the pavement surface until the applied resin mortar is completely cured, especially if multiple layers are required to be overcoated, the construction period is long and inconvenient. . On the other hand, according to the “dry construction method”, it is possible to produce a flooring having a grid pattern joint pattern in a place where quality control is easy, such as a factory, and has a uniform and high quality joint pattern. It has the advantage that a paved surface can be formed. In addition, at the construction site, it is possible to form the floor surface by simply spreading the floor material prepared in advance, so that the construction period can be shortened and the period for restricting pedestrian traffic can be minimized. It has excellent characteristics.

As such a dry construction method, for example, the one shown in Patent Document 1 is known. In Patent Document 1, a pattern layer made of polymer cement is formed on the surface of a nonwoven fabric impregnated with a resin, and a decorative sheet having a two-layer structure of the nonwoven fabric and the pattern layer thus formed is brought into the field and applied to the construction surface. A method of sticking is disclosed. Here, by applying a pattern having a grid-like joint pattern as the pattern layer, the invasion of pedestrians is limited until the formwork is pasted or the resin mortar applied as a paving surface is cured. There is no need, and there is a possibility that a paved surface having a uniform grid-like joint pattern can be quickly constructed.
Japanese Patent Application Laid-Open No. 7-171928

  However, according to the method of Patent Document 1, it is necessary to carry a two-layered decorative sheet formed in a large format to the construction site and cut it according to the size of the construction surface. The decorative sheet to be brought in has also been enlarged. That is, there is a problem that the risk of bending and cracking in the course of carrying in increases, making it unsuitable for construction on a large construction surface. In addition, the quality of joint pattern on the decorative sheet alone (the joint pattern is not distorted or displaced) is ensured to some extent by factory production, but the relative position between the construction surface and the decorative sheet It was difficult to adjust the relationship, and it was difficult to ensure the design.

  Specifically, for example, when the construction surface is curved, the decorative sheet attached thereto is also distorted, and the joint pattern may be curved in a form accompanying the curvature of the construction surface. Occurs (see FIG. 9A). In addition, when forming joint patterns on a straight and long construction surface like a platform of a station, the relative parallel relationship between the joint pattern drawn on the decorative sheet and the longitudinal direction of the platform is maintained. For example, if the end face of the platform and the joint pattern are not in a parallel positional relationship, even if the joint pattern itself is regularly arranged in a grid pattern, walking with an impression tilted obliquely with respect to the station platform (See FIG. 9B).

  Thus, when the joint pattern is curved or tilted with respect to the reference direction of the construction surface, it is necessary to redo the construction, which is extremely inefficient. In addition, if time is taken for redoing, the construction period becomes long, and there arises a problem that the merit as the dry construction method cannot be fully exhibited.

  Therefore, in view of the above-described problems, an object of the present invention is to provide a pavement method that is suitable for construction on a wide construction surface and that can form a pavement surface quickly and with a high degree of completion without requiring a skilled technique.

  The pavement method according to the present invention includes the following: “on the surface of the nonwoven fabric impregnated with a resin mainly composed of methyl methacrylate monomer, a straight vertical alignment line, a horizontal alignment line orthogonal to the vertical alignment line, and the vertical alignment A non-land adjustment layer forming step for forming a substantially square non-surface adjustment layer in which an oblique alignment line for confirming an orthogonal state between the line and the horizontal alignment line is formed, and a resin mortar comprising the resin and the aggregate A joint layer that is affixed to the surface of the unevenness adjusting layer, and a part of the joint layer that is formed on the surface of the joint layer and is visibly exposed. A pattern layer preparation step of preparing a pattern layer comprising a surface layer material configured to have a grid-like joint pattern, and a carry-in step of bringing the unevenness adjustment layer and the pattern layer into a construction site , Surface of construction surface A reference line marking step for drawing a reference line serving as a reference for the grid-like joint pattern, and the unevenness adjustment layer carried by the carrying step according to the reference line, the surface of the construction surface A non-land surface adjustment layer adhering step for continuously spreading and adhering to the substrate, and an alignment confirmation step for confirming that the vertical alignment line, the horizontal alignment line, and the diagonal alignment line are aligned in a straight line. And the pattern layer carried in by the carrying-in step on the surface of the non-land-adjusting layer stuck in the non-landing layer adhering step is continuously along the vertical alignment line and the horizontal alignment line. A pattern layer adhering step for adhering the seams between adjacent non-land surface adjustment layers continuously spread and the seams between the pattern layers so as not to overlap each other. "What to do" That.

  Here, “impregnation” includes not only the state in which the resin penetrates the entire interior of the fiber but also the state in which the resin penetrates only in the vicinity of the surface layer of the fiber.

  In addition, “nonwoven fabric” refers to fabrics that are made of fibers without using knitting and weaving methods. For example, inorganic fibers such as glass fibers, natural fibers such as cotton, and rayon and nylon. Examples thereof include those formed by combining synthetic resin fibers such as polyester and aramid by mechanical, chemical, heating or using a solvent to form a cloth.

  Furthermore, the “vertical alignment line” and the “horizontal alignment line” are not limited as long as the position where the pattern layer is applied is known. For example, ink drawing, oil-based pen, chalk, paint, and other methods for drawing with a known writing instrument. Examples thereof include engraving, quenching, and embedding an appropriate mark member. In short, any mark may be used as long as it is easily visible as a mark for the position where the pattern layer is stuck.

  The “aggregate” is not particularly limited as long as the particle size is 5 mm or less. For example, powdered selben, quartzite, calcium carbonate, titanium, cryolite, perlite, vermiculite, styrene resin foam Body, clay, kaolin, talc, barium carbonate, mica.

  Furthermore, the “non-land adjustment layer” is a layer that can absorb irregularities present on the base of the construction surface and form a smooth surface. In addition, “according to the reference line” means that the uneven surface adjustment layer is formed so that the joint pattern is formed in a desired alignment state on the surface of the pattern layer arranged along the vertical alignment line of the uneven surface adjustment layer. Shows the state of arranging. In other words, when vertical alignment lines are formed in a substantially parallel state with respect to the four sides of the square uneven adjustment layer, the four sides should be arranged in parallel along the joint pattern extending direction. It ’s fine. On the other hand, when the vertical alignment line or the like is inclined with respect to the four sides of the square-shaped uneven adjustment layer, the joint pattern of the pattern layer arranged thereon is in a desired alignment state. As described above, the arrangement angle of the uneven adjustment layer may be adjusted (tilted). As a method of arrangement, a state in which a non-land adjustment layer arranged along a reference line is used as a base point, and other non-land adjustment layers are continuously spread and pasted next to each other and the like. In other words, in addition to arranging all the non-land adjustment layers along the reference line, other non-land adjustment layers (not along the reference line) with the non-land adjustment layer arranged on the reference line as the base point Including the case of continuous arrangement.

  Further, “continuously spread along the vertical alignment line and the horizontal alignment line” indicates a state in which the pattern layer is spread along the vertical alignment line and the horizontal alignment line one by one. Furthermore, “so that the seams between the non-land surface adjustment layers and the seams between the pattern layers do not overlap each other” means that the pattern is continuously located almost directly above or very close to the seam between the non-land surface adjustment layers. The state where the seams between the layers are arranged is shown, and the state where the seams between the non-land adjustment layers and the seams between the pattern layers partially overlap each other, for example, the state where they intersect is not included.

  Therefore, according to the pavement method of the present invention, a large non-woven fabric is impregnated with a resin mainly composed of methyl methacrylate monomer (hereinafter simply referred to as “MMA resin”). And in the state which resin hardened substantially, it cut | disconnects in a substantially square unit shape, and forms the vertical alignment line, the horizontal alignment line, and the diagonal alignment line which become the mark of the sticking position of a pattern layer on the surface. Here, the “horizontal alignment line” may be a line orthogonal to the “vertical alignment line”, and does not need to be matched with the square outer shape of the non-land adjustment layer. That is, it may be formed parallel to the four sides of the uneven adjustment layer, or may be provided inclined at an arbitrary angle. However, if it is formed in a state substantially parallel to the four sides of the uneven adjustment layer, the correlation between the reference line and the grid-like joint pattern can be grasped when drawing the reference line in the “reference line marking process” described later. This is more preferable because the extending direction of the grid-like joint pattern and the extending direction of the reference line need only be aligned in parallel, and it is not necessary to consider the inclined state. In this way, a non-land adjustment layer is produced (“non-land layer production process”).

  On the other hand, a MMA resin is uniformly applied to form a joint layer having a desired unit shape, and a surface layer material having a grid-like joint pattern is formed on the surface thereof, thereby producing a pattern layer (“pattern layer”). Manufacturing process "). The joint pattern is formed by exposing a joint layer as a foundation from a gap between the surface layer members partitioned in a grid pattern. Then, the produced uneven adjustment layer and the pattern layer are carried into the construction site (“carrying-in process”).

  At the construction site, a reference line serving as a reference for a desired grid-like joint pattern is drawn on a layer (soil, asphalt, concrete, etc.) that is the foundation of the construction surface (“reference line marking process”). Then, the loaded non-land adjustment layer is continuously spread along the reference line (“non-land adjustment layer sticking step”). As a result, fine irregularities existing on the surface of the layer serving as the base are filled, and a smooth surface shape is formed. Then, the operator confirms the alignment state of these lines through the vertical alignment line, the horizontal alignment line, and the diagonal alignment line formed on the surface of the uneven adjustment layer (“arrangement confirmation process”). For example, if adjacent non-land adjustment layers are distorted or the shape of the non-land adjustment layer of the unit member is distorted, the vertical alignment line and horizontal alignment line are not aligned in a straight line and are distorted. Therefore, it is easy to visually check the degree of distortion.

  In addition, even if the vertical alignment line and horizontal alignment line are aligned on a straight line, if there are curves or steps on the construction surface, the grid-like joint pattern on the pattern layer placed on it will be slightly distorted. There is a fear. However, according to the present invention, since an oblique alignment line is further provided, it is possible to confirm not only the vertical and horizontal directions but also the degree of alignment in the oblique direction. As a result, it is possible to more accurately confirm the alignment state of the vertical alignment line and horizontal alignment line, and it is possible to easily find the step and curvature of the construction surface.

  Then, a pattern layer is continuously spread and pasted on the surface of the non-land adjustment layer (“pattern layer pasting process”) to complete the paved surface. Here, the seams between the continuous pattern layers are laid so as not to overlap the seams of the unevenness adjusting layer.

  As described above, according to the pavement method of the present invention, since a non-land adjustment layer can be formed by continuously laying a plurality of non-land adjustment layers produced in a substantially square unit shape, the non-land By adjusting the number of adjustments, the construction surface can be easily increased in size. Also, by optimizing the size of the uneven adjustment layer per sheet, it can be made more easily transportable and efficient.

  Furthermore, according to the present invention, since the vertical alignment line and the horizontal alignment line, which are the marking attention marks of the pattern layer, are formed in the uneven adjustment layer, the pattern layer can be attached only by arranging the uneven adjustment layer. The position can be known relatively accurately, and the labor required for attaching the pattern layer can be greatly reduced. In addition to the vertical alignment line and the horizontal alignment line, in addition to the vertical alignment line and the horizontal alignment line, the diagonal alignment line is further formed, so that the alignment relation of the grid-like joint pattern can be confirmed more accurately. Specifically, for example, even if the construction surface is curved or has a step, checking the diagonal alignment line is not only a vertical and horizontal parallel relationship but also a three-dimensional (raised or stepped Therefore, fine adjustment of the arrangement position of the pattern layer (accurately, the joint pattern formed on the pattern layer) to be pasted thereon can be performed more accurately and easily. Therefore, it is possible to provide a pavement layer having a high design property.

  Moreover, in the conventional wet method, in order to draw a desired joint pattern, an ink marking process is required for all joint lines. Here, the “inking process” means that the position of the pattern layer is adjusted so that a desired joint pattern can be drawn along the extending direction of the construction surface (in this case, the platform of the station). This is a process of drawing linearly on the surface, and it was necessary for the operator to draw one by one while visually checking. For this reason, when the construction surface is relatively wide and it is necessary to attach a large amount of pattern layer, the work time and labor required for the ink marking process increase, which has been a foothold for shortening the work period.

  On the other hand, according to the pavement method of the present invention, since the reference line marking process is provided, it is only necessary to perform marking of the reference line for attaching the non-land adjustment layer as the base point. And the vertical alignment line etc. drawn on the surface are regularly arrange | positioned only by spreading | laying the unevenness adjustment layer continuously along the said reference line. Therefore, the operator can attach the pattern layer with the vertical alignment line as a mark, and the labor and time required for the inking process can be greatly reduced.

  In addition, depending on the shape of the construction surface and the method of laying the unevenness adjusting layer, it may be possible that the continuous vertical alignment line is distorted. In such a case, it is necessary to correct the guidelines at the construction site. In such a case, in addition to the configuration of the present invention, “an ink that corrects the alignment state of the vertical alignment line, horizontal alignment line, or diagonal alignment line after the arrangement confirmation step and before the pattern layer application step” It is good also as a structure which further comprises a "leading correction process."

  By providing such a process, a pavement layer having a more beautiful joint pattern can be formed. In addition, although there is an aspect that increases the labor involved in the correction ink marking, it is a guideline (vertical alignment line, etc.) that serves as a mark in advance compared to the conventional ink marking process in which all guidelines are drawn on the construction site from the beginning. As a result of the drawing, the guideline can be completed in a very short time and effort, and a beautiful pavement layer can be produced with much less labor than the amount of work related to the conventional inking process.

  In addition, according to the present invention, since the non-land adjustment layer is prepared in advance in a factory or the like and is brought into the construction site and placed in a cured state, the time required for application and hardening of the non-land adjustment layer is greatly increased. Reduced. In addition, it is possible to create a non-land adjustment layer in advance in a place where the temperature, humidity, and finish perfection can be easily controlled, such as in factories, etc., so that it is not affected by climatic conditions at the construction site, and is continuous. By using a relatively simple method of laying down, it is possible to form the uneven adjustment layer quickly and with a high degree of completion.

  The pattern layer has a two-layer structure of a joint layer exposed as a joint pattern and a surface layer material forming the surface layer. Therefore, even if the unevenness adjusting layer that forms the foundation is made of a thin nonwoven fabric and cracks may occur in the carrying-in process, the unevenness adjusting layer cracked in the joint layer and the surface layer material. Therefore, there is no possibility of deteriorating the design of the paved surface. Thereby, a paved surface with high designability can be formed very quickly and easily. In addition, since the entire non-land adjustment layer can be configured by laying a non-land adjustment layer of a predetermined shape, there is no need for a process for producing a large non-land adjustment layer and cutting it according to the shape of the construction surface. It is also suitably applied to the construction surface.

  Furthermore, according to the present invention, since the seam between the non-land adjustment layer continuously spread and the pattern layer spread on the surface thereof is arranged so as not to overlap each other, the non-land adjustment layer expands due to heat or the like. Even in this case, the seam is difficult to spread by being pressed against the pattern layer, and it is possible to make the structure difficult to crack. In addition, since the uneven adjustment layer is difficult to crack, the pattern layer attached to the surface is not easily cracked, and a highly durable pavement surface can be provided.

  In addition, according to the present invention, since the MMA resin is used for the unevenness adjusting layer, the joint layer, and the surface layer material, the polymerization reaction proceeds at room temperature and is cured relatively quickly. Thereby, it is possible to shorten the time for preparing the unevenness adjusting layer and the pattern layer, which is effective. Moreover, since the same resin (MMA resin) is used mutually, it is excellent in adhesiveness and it is hard to raise | generate peeling after construction. Thereby, a long-life and economical pavement surface can be provided.

  The joint pattern appearing in the pattern layer is not particularly limited. However, if the joint layer is formed as a joint pattern in which the joint part is linearly arranged at the boundary part between the adjacent pattern layers, Since the joint pattern is located at the joint, it becomes difficult to understand the joint, and a more natural finished pavement surface can be obtained, which is more preferable.

  Moreover, in the pavement method of the present invention, “the oblique alignment line is formed with a width wider than the vertical alignment line and the horizontal alignment line”.

  By the way, the vertical alignment line, the horizontal alignment line, and the diagonal alignment line need to be formed with a width that is at least easily visible to the operator. Because the line has a different function, the required width may also vary. Specifically, the vertical alignment line and the horizontal alignment line function as sticking positions for the pattern layer disposed on the vertical alignment line, while the diagonal alignment line is the vertical alignment line and the horizontal alignment line. It functions as a confirmation line for confirming the alignment state (and eventually the alignment state of the joint pattern of the pattern layer disposed thereon).

  Here, if the vertical alignment line and horizontal alignment line are too wide, for example, if they are formed with a width wider than the width of one joint line, it will vary depending on where the end face of the pattern layer is aligned. May occur, and the adhering position between adjacent uneven adjustment layers may be shifted. Thereby, the vertical alignment line and the horizontal alignment line on the uneven surface adjustment layer in the entire construction surface may not be aligned on the straight line and may be distorted, but according to the present invention, the diagonal alignment line is the vertical alignment line. In other words, the vertical alignment line and the horizontal alignment line are formed with a width narrower than that of the diagonal alignment line. The wearing position is difficult to shift, and a large number of pattern layers can be aligned more accurately.

  On the other hand, since the diagonal alignment line mainly has a function of confirming the alignment state of the uneven adjustment layer, it is desirable that the diagonal alignment line is as wide as possible so as to be easily visible. Therefore, in the present invention, the diagonal alignment line is formed with a width wider than the vertical alignment line and the horizontal alignment line. By optimizing in this way, the difference between the vertical alignment line, the horizontal alignment line, and the diagonal alignment line is clarified, and consideration is given so as not to be confused, that is, confirmation is easy.

  Further, in the pavement method of the present invention, the "substantially square uneven adjustment layer has at least two vertices located on a diagonal line for confirming the orthogonal state of the vertical alignment line and the horizontal alignment line. An oblique confirmation marker is further formed ".

  Here, the "diagonal confirmation marker" is provided at least at two opposing points among the vertices of the uneven adjustment layer, and may be formed at all four vertices, or any one set The two points may be provided. The shape or form may be any shape as long as the position of the vertex of the non-land adjustment layer is known, and examples include marking by filling the vertex, embedding a ridge or a mark member, or engraving. However, it is preferable that the difference from the “oblique alignment line” is clearly understood.

  Therefore, according to the pavement method of the present invention, the oblique confirmation marker for confirming the orthogonal state between the vertical alignment line and the horizontal alignment line is further formed. Thereby, the confirmation operation | work of the orthogonal state of a vertical alignment line and a horizontal alignment line can be made more reliable and simple. Furthermore, the difference in function from the diagonal alignment line is that the seams between successive uneven adjustment layers can be easily confirmed.

  As described above, according to the pavement method of the present invention, by continuously laying a plurality of unevenness adjustment layers prepared in a substantially square unit shape, a total unevenness adjustment layer on a wide construction surface is formed. Therefore, it is possible to easily cope with the enlargement of the construction surface by adjusting the number of unit-shaped uneven adjustment layers to be spread. In addition, since the vertical alignment line, horizontal alignment line, and diagonal alignment line, which are the marking attention marks of the pattern layer, are formed on the uneven adjustment layer, the pattern layer application position can be obtained simply by arranging the uneven adjustment layer. Can be known relatively accurately, and the labor required for attaching the pattern layer can be greatly reduced. Thereby, a pavement layer having a beautiful grid-like joint pattern can be easily provided.

  Hereinafter, a paving method according to an embodiment of the present invention will be described with reference to FIGS. 1 to 8. FIG. 1 is a schematic cross-sectional view schematically showing a cross-section of a pavement surface produced by the pavement method of the present invention, FIG. 2 is a perspective view of a non-land adjustment layer, and FIG. 3 is a perspective view of a pattern layer. 4 is a perspective view of the formwork, FIG. 5 is an explanatory view for explaining the process of producing the pattern layer, FIG. 6 is an explanatory view showing the process for attaching the unevenness adjusting layer, and FIG. It is explanatory drawing which shows a layer sticking process, FIG. 8: is sectional drawing which shows the joint line of a non-land adjustment layer and a pattern layer.

  As shown in FIG. 1, the pavement surface 1 produced by the pavement method of the present embodiment includes a non-land adjustment layer 3 disposed on the surface of a construction surface 2 such as a station platform, and the surface of the non-land adjustment layer 3. And the pattern layer 4 disposed on the surface. A protective layer 5 is formed on the surface of the pattern layer 4.

  The unevenness adjusting layer 3 is a layer that fills in fine irregularities on the surface of the construction surface 2 to form a smooth surface, and is a resin having a methyl methacrylate monomer as a main component in a known nonwoven fabric (hereinafter simply referred to as “MMA resin”). It is formed by impregnating. Here, as a known non-woven fabric, for example, various fibers such as glass fiber, cotton, rayon, nylon, polyester, aramid, etc., which are bonded as they are without using a method such as knitting or weaving, are made into a cloth shape. The material and the bonding method are not particularly limited. Moreover, the soft thing is selected as the MMA resin used for the unevenness adjustment layer 3 of this example. Thereby, the followability with respect to the unevenness existing on the surface of the construction surface 2 is good, and it is possible to suitably perform the uneven treatment, and it has the effect that it is difficult to cause cracks during transportation.

  The shape of the non-land adjustment layer 3 may be any geometric shape that can be easily spread continuously without gaps. In this example, a square shape of about 600 mm square as shown in FIG. 2 is used. Has been. The thickness is not particularly limited and can be appropriately selected according to the material of the nonwoven fabric used and the surface state of the construction surface 2. In addition, in the cross-sectional schematic diagram shown in FIG. 1, in order to demonstrate the cross-sectional state of the pavement surface 1, the thickness of each layer is typically shown, and scales etc. are not specified in the state of drawing but are selected arbitrarily. The

  Further, on the surface of the uneven adjustment layer 3, a vertical alignment line 6 that becomes a mark when a pattern layer 4 to be described later is attached, a horizontal alignment line 7 formed so as to be orthogonal to the vertical alignment line 6, and An oblique alignment line 8 for confirming an orthogonal state between the vertical alignment line 6 and the horizontal alignment line 7 is formed.

  Here, as a method of forming the oblique alignment line 8 so as to “confirm the orthogonal state between the vertical alignment line 6 and the horizontal alignment line 7”, in this example, first, in the present embodiment, a square-shaped unevenness adjustment layer of about 600 mm square. 3, the vertical alignment line 6 is formed near the approximate center of one side (position of about 300 mm from the end face). Then, the horizontal alignment line 7 is formed so as to be orthogonal to the vertical alignment line 6 and in the vicinity of the approximate center of the other side (position of about 300 mm from the end face). By forming the respective lines as described above, the vertical alignment line 6 and the horizontal alignment line 7 intersect each other in the vicinity of the approximate center of the unevenness adjusting layer 3. Then, by crossing the vertical alignment line 6 and the horizontal alignment line 7 by drawing the diagonal alignment line 8 from an arbitrary vertex (for example, the vertex 9a) of the unevenness adjusting layer 3 to the vertex 9b opposite to the vertex 9b. Can be formed. Since the non-land adjustment layer 3 has a substantially square shape, the diagonal alignment line 8 is formed in a state inclined by approximately 45 degrees with respect to the vertical alignment line 6 and the horizontal alignment line 7.

  The vertical alignment line 6, horizontal alignment line 7, and diagonal alignment line 8 can be formed by, for example, drawing with ink, oil-based pen, chalk, paint, or other known writing tools, engraving, quenching, Examples of the method include embedding the mark member. In short, any material can be used as long as it is easily visible as a mark of the position where the pattern layer 4 is adhered. The vertical alignment line 6 and the horizontal alignment line 7 are formed with a substantially equal width W1, and the width W2 of the diagonal alignment line 8 is formed thicker than W1.

  Further, in the non-land adjustment layer 3, an oblique confirmation marker 11 is further formed at a vertex 10 different from the vertexes 9a and 9b facing each other. More specifically, the oblique confirmation marker 11 includes an oblique confirmation surface marker 11a formed on the surface of the non-land adjustment layer 3 and an oblique confirmation formed on the end surface where the apex 10 is located, as shown by a one-dot chain line circle. And an end face marker 11b for use. As a method for forming the oblique confirmation marker 11, the oblique confirmation surface marker 11a, and the oblique confirmation end face marker 11b, a method similar to that for the vertical alignment line 6 or the like can be adopted, and the description thereof is omitted.

  As shown in FIGS. 1 and 3, the pattern layer 4 includes a joint layer 12 and a layer made of a surface layer material 13. The joint layer 12 is a layer located in the lower layer of the surface layer material 13 and has a function as a layer expressing the color of the joint portion 14. Resin mortar is applied as a material used for the joint layer 12. Resin mortar uses resin as a binder and uses only aggregates with a particle size of 5 mm or less. Compared to general cement concrete using water as a binder, it has mechanical strength and water resistance. Excellent wear resistance, electrical insulation and chemical resistance. As the resin mortar binder used for the joint layer 12 of the present embodiment, MMA resin is particularly applied. The aggregate is not particularly limited as long as the particle size is 5 mm or less, for example, powdered selben, quartzite, calcium carbonate, titanium, cryolite, perlite, vermiculite, styrene resin foam, clay, Examples include kaolin, talc, and barium carbonate. Further, the joint layer 12 is blended with a pigment for expressing the color of the joint portion 14.

  The surface layer material 13 is a layer mainly constituting the pattern layer 4, and the same MMA resin mortar as the joint layer 12 is applied. The MMA resin is an acrylic resin having a methyl methacrylate monomer as a main component, and has characteristics such as excellent fast curing and low temperature curability and little change with time after curing. In addition, the surface layer material 13 of the present embodiment is blended with a wax having a function of blocking oxygen in the air by forming a film on the surface of the surface layer material 13 and protecting the polymerization reaction of the MMA resin. ing. The wax is not particularly limited, and examples thereof include higher fatty acids such as paraffin wax, polyethylene wax, stearic acid, and hydroxystearic acid. Further, the surface layer 13 is further added with a curing agent (benzoyl peroxide or the like) for inducing a curing reaction of the MMA resin, or a curing accelerator (amine-based curing accelerator or the like).

  Further, the surface layer material 13 is divided into rectangular shapes, and the joint layer 12 located on the base is exposed so as to be visible, thereby forming a grid-like joint portion 14.

  The protective layer 5 (see FIG. 1) is a layer that covers the surface of the surface layer material 13 and the joint portion 14, and may be any resin as long as it is a permeable resin. For example, a known skin-based resin whose main component is an acrylic resin emulsion, an acrylic resin (which may be the MMA resin of this embodiment used for the surface layer 13 or the like), or the like is applied.

  By the way, according to the pavement method of this embodiment, in order to produce the pattern layer 4, the formwork 15 as shown in FIG. 4 is used. The mold 15 functions as a mold material when the pattern layer 4 is produced by filling the interior with MMA resin mortar, and examples of the material include an appropriate metal such as stainless steel, wood, and ceramics. . As a shape, the bottom surface has a flat plate shape substantially equal to the joint layer 12, and the three directions around the bottom surface are surrounded by a plate-like support member 17 that is suspended from the bottom surface. The upper surface is open, and the support member 17 is provided with a joint fixing portion 18 capable of locking a joint member 16 to be described later. The support member 17 of the mold 15 of this example has a height of about 10 mm and a width of about 600 mm, and the joint fixing portion 18 has a height of about 2 mm and a width of 10 mm (from the joint member 16 of the joint member 16). It is formed by providing a notch having a shape substantially equal to the shape.

  Moreover, according to the pavement method of this embodiment, in order to produce the pattern layer 4, the joint member 16 as shown in FIG. 5 is used. The joint member 16 is a member for forming the joint portion 14, and details thereof are omitted. However, an adhesive layer made of a rubber-based adhesive is provided on the back side of the foamed resin body made of polyurethane, and on the front side. Is provided with a protective sheet made of polyethylene terephthalate so that moisture and resin mortar do not easily penetrate. The shape is a band-like object having a thickness of about 2 mm and a width of about 10 mm, and an object having an appropriate length (for example, about several tens of meters) is cut into a predetermined length and adhered onto the joint layer 12. Thus, it functions as the joint member 16.

  Next, the pavement method of the present invention will be described. In the non-land adjustment layer production step, the non-land adjustment layer 3 as shown in FIG. 2 is produced. First, in a production site such as a factory, a known nonwoven fabric is impregnated with MMA resin and waits until it is cured. Then, it is cut into a predetermined shape (approximately square of about 600 mm square in this embodiment).

  And the vertical alignment line 6 and the horizontal alignment line 7 are formed in the surface of the nonwoven fabric cut | disconnected by the square shape of about 600 mm. As a method of forming the vertical alignment line 6 and the horizontal alignment line 7, for example, ink drawing, oil-based pen, chalk, paint, a method of drawing with other known writing tools, engraving, quenching, embedding appropriate mark members, etc. In this example, a drawing method using a known oil-based ink is employed. The vertical alignment line 6 is a square-shaped non-woven fabric, from approximately the center of an arbitrary side (distance of about 300 mm from the apex) to approximately the center of the other side corresponding thereto (that is, the non-woven fabric is approximately halved). Drawn). The horizontal alignment line 7 is drawn so as to intersect the vertical alignment line 6 substantially vertically and so as to divide the nonwoven fabric into approximately half. By forming in this way, the vertical alignment line 6 and the horizontal alignment line 7 are formed in a cross so as to intersect in the vicinity of the approximate center of the square nonwoven fabric. The vertical alignment line 6 and the horizontal alignment line 7 are formed with substantially the same width, can be easily inspected by the operator, and have a width W1 that is approximately half or less of the width of one joint portion 14. Is formed.

  Here, the “joint portion 14” corresponds to the “joint line” of the present invention.

  And the diagonal alignment line 8 is formed toward the vertex 9b which opposes this from the arbitrary vertex 9a of a square-shaped nonwoven fabric. As a method of forming the diagonal alignment line 8, the same method as the vertical alignment line 6 and the horizontal alignment line 7 described above is employed. Further, the width W2 of the oblique alignment line 8 is formed to be thicker than the width W1 and equal to or less than the width of one joint portion 14. Here, since the nonwoven fabric has a substantially square shape, when the diagonal alignment line 8 is drawn from the vertex 9a to the vertex 9b, the vertical alignment line 6, the horizontal alignment line 7, and the diagonal alignment line 8 are close to each other in the vicinity of the approximate center of the nonwoven fabric. Cross at. By forming in this way, the vertical alignment line 6 and the horizontal alignment line 7 inevitably intersect substantially vertically. Further, the diagonal alignment line 8 is formed in an inclined state with respect to the vertical alignment line 6 and the horizontal alignment line 7 at approximately 45 degrees.

  In the unevenness adjustment layer manufacturing step, an oblique confirmation marker 11 (hereinafter simply referred to as “marker 11”) is further formed on the surface of the nonwoven fabric described above. As shown in FIG. 2, the markers 11 are formed in a pair on opposite vertices 10 different from the vertices 9 a and 9 b. Since the forming method is the same as that of the vertical alignment line 6 and the like, the description thereof is omitted. The shape of the marker 11 is not particularly limited and may be any shape as long as the position of the vertex 10 can be confirmed. In this example, the shape of the marker 11 is relatively simple and easy to form. In addition, a substantially triangular shape is used in which it is easy to confirm the alignment state of the continuous markers 11 during the sequence confirmation step (described later).

  More specifically, the marker 11 has an oblique confirmation marker 11a (hereinafter simply referred to as “marker 11a”) formed on the surface of the nonwoven fabric and a vertex 10 as shown in a one-dot chain line circle in FIG. An oblique confirmation marker 11b (hereinafter simply referred to as “marker 11b”) formed on the end face is provided. In FIG. 2, the marker b is shown only on one end face shown in the figure, but the same marker 11 b is also formed on the end face on the omitted side in a direction substantially perpendicular thereto.

  Subsequently, in the pattern layer manufacturing step, as shown in FIG. 5A, the mold 15 is filled with the MMA resin mortar of this example, and the surface is leveled with a trowel or the like so that the surface has a smooth and uniform thickness. I will do it. The support member 17 of the mold 15 of the present example has a joint fixing portion 18 provided as a cut portion having a thickness of about 2 mm at the upper end portion thereof. Therefore, by filling the MMA resin mortar with the vicinity of the bottom of the joint fixing portion 18 as a mark, the joint layer 12 having a thickness of about 8 mm as a whole is formed. In addition, as thickness of the joint fixing | fixed part 18 and the joint layer 12, it is not limited to this value, It can change suitably with the state of the construction surface 2, and the conveyance circumstances. For example, if the thickness of the joint layer 12 and the surface layer material 13 to be described later is reduced, the weight of the pattern layer 4 per sheet is reduced, so that a large amount of the pattern layer 4 can be transported at one time. Moreover, if the thickness of the joint layer 12 and the surface layer material 13 to be described later is increased, there is an effect that the possibility of cracking or chipping of these layers during transportation is reduced.

  Next, as shown in FIG. 5 (b), the joint member 16 is adhered to the surface of the joint layer 12 in a substantially cured state (at least cured so as not to deform the surface). Wearing process). Specifically, the rod-shaped joint member 16 is locked to the joint fixing portion 18, the adhesive layer of the joint member 16 is pressed against the surface of the joint layer 12, and the joint member 16 is arranged linearly.

  In the substantially square joint layer 12, the joint member 16 is attached to two peripheral sides, and the other two sides are opened (the joint member 16 is not attached). 14 and the periphery 20b (refer FIG. 3) which does not have the joint part 14 exist. With this configuration, when the plurality of pattern layers 4 are continuously spread, the periphery 20a having the joint portion 14 and the periphery 20b of the other pattern layer 4 not having the joint portion 14 are disposed adjacent to each other, The 14 seams can be made difficult to understand and can be constructed as natural and continuous.

  Next, as shown in FIG. 5C, MMA resin mortar to be the surface layer material 13 is applied to the surface of the joint layer 12 in a state where the joint member 16 is adhered. Then, the surface is smoothed so as to be substantially equal to the thickness of the joint member 16. By forming in this way, the surface layer material 13 substantially equal to the thickness of the joint member 16 (about 2 mm in this example) can be formed. At this time, since the thickness of the support member 17 is formed substantially equal to the thickness of the joint layer 12 and the surface layer material 13, by sliding a trowel along the upper end portion of the support member 17, The smooth surface material 13 can be formed more easily.

  Then, as shown in FIG. 5D, the joint member 16 is peeled off from the joint layer 12 in a state where the applied MMA resin mortar is substantially cured. Thereby, the pattern layer 4 which has the joint part 14 substantially the same as the shape of the bonded joint member 16 is completed (refer FIG.5 (e)).

  Subsequently, in the carrying-in process, the non-land adjustment layer 3 and the pattern layer 4 are carried into the construction site as separate bodies. The pattern layer 4 may be released from the mold 15 and carried into the construction site, or may be carried into the construction site in a state where it is not released from the mold 15 (FIG. 5E). Also good. When the mold 15 is released from the mold 15 and is carried into the construction site, the time required for the construction at the site can be shortened because the labor of releasing the mold at the construction stage can be saved. On the other hand, when carrying into the construction site without releasing the mold, it is possible to prevent the design layer from being deteriorated due to bending or chipping of the pattern layer 4 during transportation.

  Then, at the construction site, a “reference line marking process” is performed in which a reference line 21 serving as a reference for the joint pattern appearing on the pavement surface 1 is drawn on the construction surface 2. In the reference line marking process, a reference line 21 is drawn on the surface of the construction surface 2 as shown in FIG. In addition, as this construction surface 2, in this example, the platform of the elongate station in which the cap stone 22 and the braille block 23 were installed is illustrated. In addition, the method of drawing the reference line 21 is not particularly limited. In this example, the reference line 21 is substantially parallel (and vertical) to the Kasaishi 22 and the Braille block 23 (that is, the Kasaishi 22 and the Braille block 23 The method of drawing a reference line 21 (along the extending direction) is illustrated. More specifically, an octopus thread dipped in ink is fixed to an arbitrary end of the braille block 23, and the octopus thread is stretched along the extending direction of the braille block 23. Then, the octopus yarn is stretched by a desired construction range, and the yarn is pressed against the other end side in a state where the yarn is tightly tensioned, and the yarn is pressed against the construction surface 2. Then, the ink soaked into the thread falls on the construction surface 2 and a linear reference line 21 is drawn.

  Next, in the “non-land adjustment layer sticking step”, the non-land adjustment layer 3 is continuously spread according to the reference line 21 as shown in FIG. First, the one uneven adjustment layer 3 is stuck along the reference line 21. As a method of attaching, an appropriate pressure-sensitive adhesive layer is provided on the back side of the uneven adjustment layer 3 at the production stage in the factory, an adhesive is applied on the construction site, or resin mortar is applied on the construction surface 2. The method of apply | coating and mounting and sticking the unevenness adjustment layer 3 is mentioned.

  And according to the non-land adjustment layer 3 stuck along the reference line 21, the other non-land adjustment layers 3 are continuously spread. Here, “according to” indicates a state in which another non-land adjustment layer 3 is continuously attached to the non-land adjustment layer 3 attached along the reference line 21 without a gap. . Since the non-land adjustment layer 3 is cut into a substantially square shape, the other non-land adjustment layers 3 are attached one after another according to the non-land adjustment layer 3 attached along the reference line 21 in this way. By doing so, it is relatively easy to align a large number of the uneven adjustment layers 3 substantially in parallel with one reference line 21.

  Next, the process proceeds to the “sequence confirmation step”. In the arrangement confirmation step, as shown in FIG. 7, the vertical alignment line 6, the horizontal alignment line 7, the diagonal alignment line 8 and the marker 11 (hereinafter referred to collectively as “line etc.”) formed in the non-land adjustment layer 3. The alignment state of the non-land adjustment layer 3 is confirmed. More specifically, the operator drops the line of sight to a position as close as possible to the surface of the unevenness adjustment layer 3 (that is, a low position) and visually observes a line from one end side to the other end side of the construction surface 2. It is confirmed whether or not the lines between the consecutive uneven adjustment layers 3 are continuously connected on a straight line. By confirming in this way, it can be confirmed easily and surely whether or not a large number of the uneven adjustment layers 3 adhered to the construction surface 2 having a relatively large area are arranged in a grid pattern.

  Here, if the construction surface 2 is curved, or if deficiencies occur in the unevenness adjustment layer manufacturing process or the unevenness adjustment layer sticking process, the vertical alignment lines 6 of the many unevenness adjustment layers 3 are arranged. Since the alignment lines 7, the alignment lines 8, the diagonal alignment lines 8, and / or the markers 11 are discontinuously distorted and arranged, it is possible to immediately recognize the state of the curve and the incomplete state. In this case, redraw the correction vertical alignment line 6 or horizontal alignment line 7 or the like ("correction inking process") or redo the uneven adjustment layer attaching process, etc. Modifications may be made to align.

  By the way, when there exists a level | step difference in the construction surface 2, for example, when there is a difference in the sticking height position of the adjacent non-land adjustment layers 3, the following problems can be considered. That is, when the marker 11 of the non-land adjustment layer 3 attached to the high position is visually confirmed from the non-land adjustment layer 3 side attached to the low position, the non-land adjustment that is attached to the high position from the low position. It is conceivable that the marker 11a on the surface of the layer 3 (see FIG. 2; the same shall apply hereinafter) cannot be confirmed, and only the end face side of the non-land adjustment layer 3 attached to a higher position can be seen. At this time, assuming that only the marker 11a is present, even if the vertical and horizontal alignment states of the tail-rough adjustment layer 3 are in place, the alignment state may not be confirmed due to the marker 11a appearing broken. obtain. On the other hand, in the present invention, the non-land adjustment layer 3 further includes the marker 11b (see FIG. 2; the same applies hereinafter), so that the non-land adjustment layer 3 can be attached from the end surface side. A mark that can be confirmed is formed. Thereby, even when there is a step on the construction surface 2, an oblique alignment state can be confirmed, and therefore the alignment state of the unevenness adjusting layer 3 can be confirmed more easily and reliably. Moreover, since the diagonal alignment line 8 is configured to have a relatively thick width W2, it is more effective for the operator to easily perform the confirmation operation.

  Next, in a pattern layer sticking process, the pattern layer 4 is stuck along the vertical alignment line 6 and the horizontal alignment line 7 which were formed in the unevenness adjustment layer 3 (refer FIG. 7). As an adhesion method between the non-land adjustment layer 3 and the pattern layer 4, the same method as that described in the adhesion method between the non-land adjustment layer 3 and the construction surface 2 can be applied. That is, a known adhesive layer may be provided on the back side of the pattern layer 4, and resin mortar or the like may be applied to the back side of the pattern layer 4 at the construction site. It may be applied. However, it is preferable that the vertical alignment line 6 and the horizontal alignment line 7 be a color or coating method that does not completely obscure the line. At this time, since the vertical alignment line 6 and the horizontal alignment line 7 are drawn in the vicinity of the center of the non-land adjustment layer 3, as shown in FIG. It arrange | positions so that the seam 25 may not overlap continuously. Further, the joint portion 14 is provided on one side of the periphery of the pattern layer 4, and the joint portion 14 is not disposed on the other side opposite to the joint portion 24. Can be disposed at the boundary portion of the joint portion 14. Therefore, the seam 24 can be made inconspicuous, which is effective. The “seam 24” corresponds to the “seam between the unevenness adjusting layers” of the present invention, and the “seam 25” corresponds to the “seam between the pattern layers”.

  According to the present invention, since the vertical alignment line 6 and the horizontal alignment line 7 are arranged in an orderly manner, the pattern layer 4 can be aligned very simply by sticking along the vertical alignment line 6 and the horizontal alignment line 7. Along with this, the joint portions 14 formed in the pattern layer 4 can be beautifully aligned in a grid pattern.

  Then, it transfers to a protective layer application | coating process. In the protective layer application step, a transparent resin is applied to the surface of the pattern layer 4 stuck on the unevenness adjusting layer 3 and cured. Thereby, the protective layer 5 is formed in the surface of the pattern layer 4, and the pavement surface 1 is completed (refer FIG. 1). Thus, by forming the protective layer 5 on the surface of the pattern layer 4, it is possible to add a deep transparency to the pattern layer 4 to improve the design, and to reduce the pattern from scratches, dirt, and discoloration due to ultraviolet rays. The layer 4 can be protected and an economical pavement surface 1 can be provided.

  As described above, according to the pavement method of the present invention, the vertical alignment line 6, the horizontal alignment line 7, the diagonal alignment line 8, and the marker 11 are formed on the non-land adjustment layer 3. The layer 3 can be easily and reliably aligned, the time required for construction can be shortened, and the alignment status can be confirmed using the vertical alignment line 6, the horizontal alignment line 7, the diagonal alignment line 8, and the marker 11. The pattern layer 4 adhered in accordance with them can be accurately aligned, and the joint portion 14 expressed in the pattern layer 4 can be aligned to provide a beautiful pavement surface 1.

  In particular, according to this example, since the diagonal alignment line 8 is provided in addition to the vertical alignment line 6 and the horizontal alignment line 7, the alignment of the non-land adjustment layer 3 not only in the vertical and horizontal directions but also from the diagonal direction. You can check the situation. Furthermore, since the diagonal confirmation marker 11 is provided, the alignment state can be confirmed more reliably, which contributes to the provision of a more beautiful pavement layer 1.

  Moreover, according to this example, since not only the marker 11a but the marker 11b is provided, even when the construction surface 2 has a step or a curve, the alignment state of the unevenness adjusting layer 3 can be confirmed more easily. Thereby, since the pattern layer 4 can be easily aligned, the joint portions 14 drawn on a large number of the pattern layers 4 can be aligned orderly and reliably, which is more effective.

  Further, the vertical alignment line 6 and the horizontal alignment line 7 are optimized to have a relatively narrow width, that is, a width equal to or less than a half of the width W1 of one joint portion 14 while being visible. Thereby, it is hard to produce dispersion | variation by where the end surface of the pattern layer 4 etc. match | combine, and many pattern layers can be aligned 4 more correctly. On the other hand, the diagonal alignment line 8 is optimized with a width W2 that is wider than the width W1 of the vertical alignment line 6 and the horizontal alignment line 7. Therefore, the diagonal alignment line 8 is differentiated from the vertical alignment line 6 and the horizontal alignment line 7 and is not confusing. The arrangement status can be checked more smoothly. Thereby, the pavement surface 1 with high design property can be provided more simply.

  Moreover, according to this example, the process of apply | coating a primer and undercoat composition is unnecessary, and a smooth surface can be formed only by sticking the unevenness adjustment layer 3. Thereby, the time which hardening requires can be reduced compared with the case where a liquid resin mortar etc. are apply | coated at a construction site and a non-land adjustment layer is formed. Moreover, since it is the method of producing the unevenness adjustment layer 3 in the factory etc. where temperature and humidity are easy to control, the unevenness adjustment layer 3 of uniform quality can be formed without requiring a relatively skilled technique.

  Further, since the joint layer 12 is visibly exposed through the joint portion 14 and the pattern layer 4 is formed, the unevenness adjusting layer 3 is not exposed from the joint portion 14. Thereby, even if a crack or a defect occurs on the construction surface 2 or the uneven surface adjustment layer 3, it does not appear on the pavement surface 1, so that the pavement surface 1 with high design can be provided.

  Furthermore, according to this example, since the soft resin mortar is applied to the non-land adjustment layer 3, the non-land adjustment layer 3 can be easily folded and carried. Thereby, it is possible to fold as necessary, or to be folded and carried on a roll, which is effective because transportation becomes easier. Moreover, when the non-land adjustment layer 3 is configured as a unit member of 600 mm square, the construction surface 2 can be adapted to the shape and size of the construction surface 2 simply by laying down continuously. It is preferably applied to pavement of a large construction surface 2.

  In addition, since the guideline 8 serving as a mark of the attachment position of the pattern layer 4 is drawn on the surface of the uneven adjustment layer 3, the attachment position of the pattern layer 4 can be determined simply by attaching the uneven adjustment layer 3. I understand. Then, by simply sticking the pattern layer 4 along the guide line 8, the joint portions 14 expressed in the pattern layer 4 are arranged in an orderly manner, so that it has a very simple grid-like joint pattern. The pavement surface 1 can be provided.

  Furthermore, according to the pavement method of this example, since the joint fixing part 18 is provided in the mold 15 for producing the pattern layer 4, the position where the joint member 16 is pasted is easy to understand, and is difficult to slip after the pasting. It can be configured. Thereby, while being able to reduce the time which a pattern layer preparation process requires, the completeness of the pattern layer 4 can be improved. Moreover, since the pattern layer 4 with high designability can be produced without requiring a relatively skilled technique, an economical pavement method can be provided.

  The present invention has been described with reference to preferred embodiments. However, the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the present invention as described below. And design changes are possible.

  In the said embodiment, although the non-land adjustment layer 3 which comprises both the diagonal alignment line 8 and the diagonal confirmation marker 11 was illustrated, it is not limited to this structure. That is, the unevenness adjusting layer 3 having only one of the diagonal alignment line 8 and the diagonal confirmation marker 11 may be used. If both the diagonal alignment line 8 and the diagonal confirmation marker 11 are provided as in this example, the alignment status not only in the vertical and horizontal directions but also in the diagonal direction can be confirmed more firmly, so that more beautiful and beautiful grids can be obtained. A pavement surface 1 having a joint pattern can be provided. On the other hand, when the non-land adjustment layer 3 having only one of the diagonal alignment line 8 and the oblique confirmation marker 11 is used, the labor required for the production of the non-land adjustment layer 3 is reduced, and therefore a lower cost pavement method. Contribute to the provision of

  Moreover, in the said embodiment, although the MMA resin was impregnated in the large-sized nonwoven fabric, and the case where it cut | cured after hardening was illustrated, it is not limited to this method. For example, a method may be used in which the nonwoven fabric cut into a predetermined unit shape is impregnated with a resin to obtain the unevenness adjusting layer 3. According to this method, there is no possibility that a crack or the like is generated in the non-land adjustment layer 3 due to the impact of cutting when the nonwoven fabric that has been soaked with resin and cut is cut. Moreover, since it can cut | disconnect in the stage of a soft cloth (nonwoven fabric), the effort which a cutting | disconnection requires can be reduced. However, if a method of cutting after soaking MMA resin as in this example is adopted, the nonwoven fabric is less likely to shrink or warp and deform when the resin is cured. It is.

  Furthermore, in the said embodiment, although the method of filling the mold 15 with the MMA resin mortar used as the joint layer 12 was illustrated, in this process, the method of filling the mold 15 with the resin mortar after spreading a known release paper It is also good. Further, instead of the release paper, a method of applying a liquid or solid release agent to the mold 15 may be used. By adopting such a method, when peeling the pattern layer 4 from the mold 15, it is possible to prevent adhesion of the pattern layer 4 to the mold 15, deformation associated therewith, etc. It is.
