Description

  The present invention relates to a pavement method, and more particularly to a pavement method having a grid-like joint pattern.

  Conventionally, a pavement method for forming a grid-like joint pattern is known as a pavement method in a road environment that places importance on the landscape. As such a pavement method, for example, a ground layer is formed by applying mortar or the like on a construction surface such as a road surface, and a plurality of bricks or tiles are adhered or laid on the surface of the ground layer, and a grid pattern is formed. A method of forming a joint pattern can be exemplified.

  In addition to the above method, a pavement method using a rod-shaped joint form member 60 as shown in FIG. Specifically, among the grid-like joint pattern, the longitudinal member 62 forming a joint portion in a predetermined direction (referred to as the longitudinal direction) and the direction substantially orthogonal to the longitudinal member 62 are disposed. A joint form member 60 composed of a transverse member 63 that forms a joint part in the horizontal direction is adhered onto the base layer 65. Next, the surface layer material is poured into the rectangular closed region R surrounded by the vertical member 62 and the horizontal member 63, and the surface of the surface layer material is adjusted so as to have a height substantially equal to the thickness of the joint form frame member 60. Level with a trowel or the like (hereinafter referred to as “surface layer coating process”). Then, after the surface layer material is cured, the joint form frame member 60 is peeled off from the base layer 65 (hereinafter referred to as “peeling process”) to form a pavement layer having a joint pattern substantially the same shape as the joint form frame member 60. This is a pavement method. According to this, it is possible to create a pavement layer having a beautiful grid-like joint pattern relatively easily without requiring the trouble of laying a plurality of bricks and tiles one by one in an orderly manner. Can do.

  On the other hand, when the rod-shaped joint form member 60 as described above is used, the adjacent horizontal members 63 (the horizontal members 63a and 63b) are separated by the vertical member 62 as shown in FIG. It has been done as a separate body. Assuming that the horizontal member 63a and the horizontal member 63b are composed of a single horizontal member 64, when the horizontal member 64 exceeds the surface of the vertical member 62 at the intersection B, it is between the base layer 65. This is because the gap S is easily generated. When a liquid surface layer material is poured into the closed region R (see FIG. 10; the same applies hereinafter) with such a gap S, the surface layer material enters the gap S and the square corners are distorted. In some cases, a desired quadrangular shape (tile pattern) may not be realized. Therefore, in order to suppress the generation of the gap S, the horizontal member 64 is divided at a predetermined interval in accordance with the interval between the adjacent vertical members 62.

  When the horizontal member 64 is used, the joint frame member height in which the thickness T1 of the horizontal member 64 and the thickness T2 of the vertical member 62 are superimposed at the intersection B between the vertical member 62 and the horizontal member 64. T is formed. In such a state, when the surface of the surface layer material poured into the closed region R is leveled with a trowel or the like in the surface layer material application step, the joint form member height T and thickness T1 (or T2) are unbalanced. There is a certain level, that is, a state having a level difference, so that the iron is caught in the level difference and it becomes difficult to smooth the surface of the surface layer material. Also from this, it is not preferable to apply the transverse member 64 formed continuously in one direction, and the divided transverse member 63a having a length substantially equal to the inner dimension between the adjacent longitudinal members 62 and The horizontal member 63b and the like are widely used.

  The above prior art is naturally performed by those skilled in the art, and the applicant is not aware of a document describing the prior art.

  By the way, it is common that a peeling process is performed before the surface layer material apply | coated at the surface material application | coating process completes hardening completely. This is because when the curing is completed in a state where the surface layer material is attached to the joint form frame member, the surface layer material and the joint form frame member are fixed, and it becomes difficult to peel the joint form frame member smoothly. . At this time, as shown in FIG. 10A, the vertical member 62 has a single shape that is continuous in the vertical direction, and therefore, one end side of the construction area of the pavement layer is peeled off from the base layer and pulled up. Thus, the other end can be peeled off at once.

  On the other hand, the transverse member 63 has a shape in which the transverse members 63 formed in the same row are divided like the transverse member 63a and the transverse member 63b (that is, a shape that is not the transverse member 64 continuously formed in one direction). Therefore, it is impossible to peel from the one end side to the other end side of the construction region at a stretch as when the vertical member 62 is peeled off. In particular, the lateral member 63 located on the inner side of the construction area requires the operator to enter the construction area and work on the surface of the surface material, so that the surface material is sufficiently cured, It was necessary to wait until the surface material was not damaged or distorted even when the work was performed on the surface. And when the peeling process of the horizontal member 63 is performed in such a state, the surface layer material and the horizontal member 63 are fixed, and it takes a very long time to peel, or the horizontal member 63 that cannot be completely peeled off. There was a problem of remaining in the joints.

  Therefore, by assembling a scaffold above the construction area and performing a peeling process from above the construction area, the operator peels off the lateral member 63 located inside the construction area without entering the surface of the surface layer material. A method is also conceivable. According to this, the transverse member 63 can be peeled off before being fixed to the surface material, but in order to create such a scaffold, cost and labor are required, and as a result, the cost required for pavement increases. There was a problem to do.

  Further, a method of applying a joint form frame member that is formed in advance in a lattice frame shape in a factory or the like and in which a vertical member and a horizontal member are integrally formed can be considered. According to this, it is not necessary to assemble a scaffold, and it is possible to perform the peeling step from the outside of the construction area (that is, without entering the surface of the surface layer material). However, according to such a pavement method, it is necessary to create a dedicated joint mold member in accordance with the shape of the construction surface for each site such as the bending / inclination of the construction surface, which is economically problematic. Further, when the grid frame-shaped joint mold member is used, there is a problem that the joint mold member is caught in the square corners of the surface layer material in the peeling process, and the corners are likely to be chipped. There was also a possibility that the designability of the would deteriorate.

  In view of the above, the present invention has an object to provide a pavement method that can form a beautiful grid-like joint pattern using a relatively simple method and is excellent in economy.

  The pavement method according to the present invention is composed of “a plurality of vertical joint patterns formed substantially parallel to a predetermined direction and a plurality of horizontal joint patterns formed in a direction substantially orthogonal to the vertical joint pattern. Is a pavement method for forming a pavement layer having a grid-like joint pattern in a predetermined construction area, a base layer application step of forming a smooth base layer, and on the surface of the base layer, A vertical line underground drawing line that draws a vertical line underground writing line that serves as a guideline for the vertical joint pattern, and a draft line drawing process that draws a horizontal line underground writing line that serves as a guideline for the horizontal joint pattern, along the vertical line underground writing line A vertical joint form frame attaching step for attaching a member to the surface of the base layer, a length substantially equal to the inner dimension of the adjacent vertical joint form member, and a thickness substantially equal to that of the vertical joint form member. Presenting rod-shaped horizontal joint form frame member, A horizontal joint form sticking step for sticking to the surface of the foundation layer along the joint line, a horizontal joint form member located on the end side of the construction area, and the same side as the horizontal joint form member A horizontal joint frame member connecting step for connecting a horizontal joint mold member disposed on the inner side of the construction area, and on the surface of the foundation layer, the vertical joint mold member and the horizontal joint A surface layer material application step of applying a liquid surface layer material so as to be substantially equal to the thickness of the mold frame member, and a horizontal joint mold member peeling that peels the connected horizontal joint mold member from the surface of the base layer A process and a vertical joint form member peeling process of peeling the vertical joint form frame member from the surface of the base layer.

  Here, “smooth” indicates a state in which relatively small irregularities existing on the construction surface are compensated to form a smooth surface shape. “Draw a draft line” refers to the process of creating a mark that serves as a guideline for the position where the joint mold member is pasted on the base layer, such as thread dipped in ink or graphite, white lime powder, etc. For example, an operation of drawing the sticking position on the base layer using an appropriate drawing means can be exemplified. Further, the “bar shape” indicates a shape of an object having an appropriate thickness and width and a straight shape, and examples thereof include a strip-shaped joint mold member having a thickness of approximately 2 mm and a width of 10 mm. . Furthermore, “stick” means that a vertical (horizontal) joint form frame member is disposed on the base layer and fixed to such an extent that it can be peeled off from the base layer in the subsequent vertical (horizontal) joint form frame peeling step. Indicates the state to be performed. For example, the joint mold member is fastened to the base layer with a small scissors, an adhesive substance such as glue is applied on the base layer, or the back side of the joint mold member (the side to be attached to the base layer) For example, a case where an adhesive layer is provided on the substrate.

  In addition, the “end side” indicates a region relatively close to the outer periphery of the construction region, and specifically, the extent to which the worker can peel the horizontal joint form frame member without entering the surface in the construction region ( That is, it shows what is disposed at a position where the hand can be extended from the outside of the construction area and the horizontal joint frame member on the base layer can be peeled off. On the other hand, “inner side” indicates a state of being arranged in an area inside the “end side”, and specifically, to the extent that the operator has reached out from the outside of the construction area, The state where it is arrange | positioned in the position which cannot perform a horizontal joint form peeling process easily is shown. “Connect” indicates a state in which at least two horizontal joint form members are connected among a plurality of horizontal joint form members arranged in the same row, and appropriate connection fittings and adhesive tapes are used. Any means may be used for connection, such as using.

  Therefore, according to the pavement method of the present invention, among the plurality of horizontal joint formwork members arranged in the same row, the horizontal joint formwork member located on the end side and the horizontal joint formwork member located on the inner side, Since these are connected, a horizontal joint formwork peeling process can be executed without an operator entering the construction area. In particular, in addition to the horizontal joint form frame member located on one end side and the horizontal joint form frame member arranged in the same row as this, the horizontal eye on the other end side arranged in the same row as this. When the ground frame member is integrally connected, it is preferable that a single row of horizontal ground frame members can be peeled at a time as in the case of peeling one vertical joint frame member.

  In addition, according to the pavement method of the present invention, since the vertical joint form frame member and the horizontal joint form frame member use a rod-like joint form frame member configured separately, when peeling from the base layer, The joint form member and the horizontal joint form member can be separated separately and independently. Furthermore, the spacing between adjacent vertical joint form members and / or horizontal joint form members can be changed flexibly according to the inclination or curvature of the construction surface, depending on the construction conditions at each site. A beautiful grid pattern joint pattern can be created without creating a dedicated joint form member.

By the way, in the above-mentioned pavement method, when a well-known connecting metal fitting such as a hook or a steer is used as a means for connecting a plurality of horizontal joint form members arranged in the same row, the surface of the joint form member is used. In some cases, a level difference is generated by the thickness of the connection fitting. In this way, when a level difference occurs, in the surface layer material application process, when the surface layer material is applied so as to have the same thickness as the joint mold member, the level difference becomes an obstacle, and a smooth surface shape cannot be formed. Can be considered.

In view of this problem, according to the pavement method of the present invention, “the horizontal joint formwork member includes an adhesive layer and a protective sheet attached to the surface of the adhesive layer, and the horizontal joint formwork member is connected. The process includes peeling the protective sheet from the surface of the adhesive layer, and then attaching a connecting sheet to the surface of the adhesive layer of the plurality of horizontal joint mold members to thereby form the plurality of horizontal joint mold members. It is characterized by being connected ".

Therefore, according to the pavement method of the present invention, the horizontal joint form frame members are connected using an integral connection sheet that is relatively thin and does not cause a step. Thereby, it is possible to easily connect the horizontal joint form frame members without hindering the workability of the surface layer material application step, which is effective. Moreover, with respect to the adhesive layer provided in the horizontal joint form frame member, a plurality of horizontal joint form frame members can be efficiently connected using a simple and reliable method of attaching a connection sheet, It is preferable because the efficiency of construction work can be promoted. Furthermore, since the horizontal joint form frame member can be peeled separately from the vertical joint form frame member by the connection operation, a pavement layer having a high design can be provided relatively easily. In addition, it is easy to simplify and reduce the weight of the members required for connection as compared with the case of using appropriate connection fittings and the like, and a more economical pavement method can be provided.

Further, in the pavement method of the present invention, “the vertical joint form frame member and the horizontal joint form frame member have a foam layer, and the surface layer material uses a resin mainly composed of methyl methacrylate monomer as a binder. It is characterized in that it is composed of a resin mortar.

Therefore, according to the pavement method of the present invention, a curing agent is added in order to apply a resin mortar containing a resin mainly composed of methyl methacrylate monomer (hereinafter simply referred to as “MMA resin”) as a binder. As a result, the polymerization reaction proceeds at room temperature and is cured relatively quickly. Thereby, construction time can be shortened and it is effective. Further, since the vertical joint form member and the horizontal joint form member (hereinafter, simply referred to as “example form member”) have a foam layer, the surface layer material in contact with the example form member is provided. That is, in the surface layer material located at the joint portion, the polymerization reaction is inhibited by oxygen contained in the voids in the foamed layer, and the curing reaction proceeds more slowly than the inside of the surface layer material. As a result, the mold member can be peeled off when the surface layer material is relatively soft (hardening is difficult to proceed), and the surface layer material and the mold member are difficult to stick together, so that the peeling is extremely smooth. There is a remarkable effect of being able to.

  Thus, according to the pavement method of the present invention, the horizontal joint formwork member can be peeled off without entering the construction area, so the horizontal joint formwork peeling process before the surface layer material is completely cured. Can be executed. Therefore, the present formwork member can be peeled off in a state where it is difficult to adhere to the surface layer material, so that the present formwork member can be cut off and remain in the joint portion, without forcibly deforming the shape of the surface layer material, The pavement layer having high design properties can be formed using a relatively simple method. In addition, since the vertical joint form member and the horizontal joint form member can be peeled separately and independently, the vertical joint form member and the horizontal joint form can be separated when the present form member is peeled from the base layer. The intersecting portion with the member does not get caught in the corner of the rectangular surface layer material partitioned in a grid pattern, and can be peeled off smoothly. In addition, it is possible to provide a pavement method capable of realizing a beautiful grid-like joint pattern more easily and inexpensively than in the case of using a dedicated joint form member corresponding to the construction conditions for each site.

  Hereinafter, a pavement method according to an embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a perspective view showing a pavement layer formed by the pavement method of the present invention, FIG. 2 is a schematic cross-sectional view schematically showing a cross-section of the pavement layer, and FIG. FIG. 4 is an enlarged cross-sectional view of the ground frame member, FIG. 4 is an explanatory view showing a draft line drawing process, and FIG. 5 is an explanatory view showing a vertical joint frame attaching process and a horizontal joint form attaching process, 6 is an explanatory view showing a horizontal joint formwork member connecting step, FIG. 7 is a perspective view showing a surface layer material applying step, and FIG. 8 is an explanatory view showing a horizontal joint formwork member peeling step. These are explanatory drawings which show a vertical joint formwork member peeling process.

  As shown in FIGS. 1 and 2, the pavement layer 1 created by the pavement method of the present embodiment has a plurality of tile pattern portions 3 partitioned and formed in a grid pattern on a base layer 2 such as concrete. The pavement layer 1 is formed. Specifically, a plurality of vertical joints 4a formed substantially parallel to a predetermined direction, and a plurality of horizontal joints formed in a direction substantially orthogonal to the vertical joints 4a. A plurality of tile pattern portions 3 are formed by the joint portion 4 constituted by the ground 4b. More specifically, the pavement layer 1 includes a smooth layer 5, a joint layer 6, a surface layer material 7, and a protective layer 8, as shown in FIG. The vertical joint 4a and the horizontal joint 4b correspond to the “longitudinal joint pattern” and the “horizontal joint pattern” of the present invention, respectively.

  The smooth layer 5 is made by filling the unevenness on the base layer 2 and smoothing, and publicly known concrete such as asphalt concrete or cement concrete can be applied, but in this example, resin mortar is applied. Concrete refers to a mixture mainly composed of cement, binder, and aggregate. Resin mortar refers to only a relatively fine aggregate having a particle size of 5 mm or less using a resin as a binder. Indicates the type of concrete used. Resin mortar has superior properties such as mechanical strength, water resistance, wear resistance, electrical insulation, and chemical resistance compared to common hydrating cement concrete with water and cement as binder. It is. Examples of the binder used for the smooth layer 5 include unsaturated polyester, epoxy, furan, polyurethane, and MMA resin. 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, kaolin , Talc, or barium carbonate.

  The joint layer 6 corresponds to a layer expressing the color of the joint part 4, and resin mortar is applied in this example. As the aggregate and the binder compounded in the joint layer 6, those exemplified for the smooth layer 5 can be applied, and a pigment for expressing the color of the joint part 4 is blended. The smooth layer 5 and the joint layer 6 correspond to the “underlying layer” of the present invention.

  The surface layer material 7 is a layer mainly constituting the tile pattern portion 3, and in this example, resin mortar is applied in the same manner as the smooth layer 5 and the joint layer 6. Note that MMA resin is particularly applied as the binder compounded in the surface layer material 7. The MMA resin is an acrylic resin having a methyl methacrylate monomer as a main component, and has features such as excellent fast curing and low temperature curing properties, and little change with time after curing. Further, the surface layer material 7 of the present embodiment further has a function of blocking oxygen in the atmosphere by forming a film on the surface of the surface layer material 7 and protecting it so as not to inhibit the polymerization reaction of the MMA resin. Is blended. Although it does not specifically limit as a kind of wax, For example, higher fatty acids, such as paraffin wax, polyethylene wax, a stearic acid, a hydroxy stearic acid, can be illustrated. Further, the surface layer material 7 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).

  The protective film 8 is a layer that covers the surface of the surface layer material 7 and the joint portion 4. For example, a known skin resin having an acrylic resin emulsion as a main component can be exemplified. In addition, in this example, the protective film 8 which has permeability | transmittance is applied especially, In addition to the function which protects the surface of the surface layer material 7 from a damage | wound and dirt, the high-quality texture with the depth is given to the said surface. Yes.

  On the other hand, in the pavement method of this example, a joint form member 9 as shown in FIGS. 3 and 5 is used as a method of forming the joint portion 4. The joint mold member 9 forms a vertical joint mold member 9a (hereinafter simply referred to as “vertical member 9a”) and a horizontal joint 4b (see FIG. 1) for forming the vertical joint 4a (see FIG. 1). For this purpose, it is composed of a horizontal joint form member 9b (hereinafter simply referred to as “transverse member 9b”). Specifically, as shown in FIG. 3A, the vertical member 9 a includes an adhesive protective tape 10, an adhesive layer 11, a foamed layer 12, and a protective tape 13. The adhesive protective tape 10 is a sheet-like substance that prevents dust and the like from adhering to the adhesive layer 11 and lowers the adhesive force, and has a softness that does not hinder cutting, bending, and peeling operations. For example, the material is not particularly limited. The pressure-sensitive adhesive layer 11 is for fixing the foam layer 12 to the joint layer 6 and is formed on the back side of the foam layer 12. As a material, a known adhesive means such as a rubber adhesive or an acrylic adhesive such as an acrylic ester is applied.

  The foamed layer 12 is a member that has a large number of voids K inside, is adhered to the joint layer 6 via the adhesive layer 11, and mainly partitions the surface layer material 7. The material may be any material as long as it has a large number of voids K, and examples thereof include foaming polyurethane resin, foaming polyethylene resin, and glass wool. It is more preferable to apply a soft material that can be easily cut by, for example, since the workability in the vertical (horizontal) joint form peeling process described later is improved. The protective tape 13 prevents the surface layer material 7 and the like from penetrating into the gap K of the foam layer 12 from the surface H side of the vertical member 9a, and the foam layer 12 and the surface layer material 7 are fixed. It is provided on the surface H side of the member 9a. As the material, a relatively thin material with low moisture permeability such as polyethylene resin, polypropylene resin, or polyethylene terephthalate is applied.

  The adhesive protective tape 10, the adhesive layer 11, the foamed layer 12, and the protective tape 13 have substantially the same surface shape. The vertical member 9a is a rod-like member having a thickness of about 2 mm and a width of about 10 mm as a whole, and a member having an appropriate length (several tens of meters, etc.) is wound in a ring shape to the construction site. Be transported. And it functions as the vertical member 9a by being cut | disconnected to predetermined length and sticking on the joint layer 6. FIG.

As shown in FIG. 3B, the horizontal member 9 b includes the same adhesive protective tape 10, an adhesive layer 11, and a foamed layer 12 as those of the vertical member 9 a, and an adhesive formed on the surface of the foamed layer 12. The adhesive protective tape 15 which protects the adhesive force of the layer 14 and the adhesion layer 14 is comprised. As the material of the adhesive layer 14 and the adhesive protective tape 15, the same material as that of the adhesive layer 11 and the adhesive protective tape 10 can be applied, and the overall shape is substantially equal to that of the vertical member 9a. The adhesive protective tape 15 corresponds to the “protective sheet ” of the present invention.

  Then, the pavement method of this invention is demonstrated. The pavement method of the present invention has eight steps, namely, “undercoat layer coating step”, “draft line drawing step”, “vertical joint form pasting step”, “horizontal joint form pasting step”, “horizontal joint” It can be broadly classified into a “formwork connecting step”, “surface layer material applying step”, “horizontal joint form peeling step”, and “vertical joint form peeling step”.

  First, in the “underlying layer application step”, as shown in FIG. 2, a smooth layer 5 and a joint layer 6 are formed on a base layer 2 such as a road, a plaza, a station concourse or a platform. Specifically, dust, dirt, dust and the like on the base layer 2 are removed, and the periphery of the base layer 2 is covered with a vinyl sheet (so-called “curing”) in order to prevent scattering of paint and the like. Then, a resin mortar is prepared by blending a resin as a binder and an aggregate, and the resin mortar is applied onto the base layer 2. Thereby, the fine unevenness which exists on the base layer 2 is made up, and the smooth layer 5 which has a smooth surface shape is formed. Here, the method for applying the resin mortar onto the base layer 2 is not particularly limited, and for example, an appropriate tool such as a roller, a brush, or a scissors is used.

  Subsequently, the joint layer 6 is formed on the surface of the smooth layer 5. That is, a resin, a pigment, and an aggregate are blended to create a colored resin mortar, and this resin mortar is uniformly applied to the surface of the smooth layer 5. At this time, it is more preferable to perform leveling (leveling the surface to be constructed) using a known surveying instrument, laser marking device, or the like. The joint layer 6 has a plurality of tile pattern portions 3 in a state in which the pavement layer 1 is looked down after the joint form member 9 is peeled in the “horizontal joint form peeling step” and the “vertical joint form peeling step” described later. It is a layer visible from above, and it is desirable to color a color contrasting with the color of the surface material 7. Naturally, it is possible to use natural colors as they are without blending pigments.

  In the “draft line drawing step”, a position for forming a predetermined joint pattern is set. Specifically, as shown in FIG. 4, using a well-known surveying instrument or laser marking device, a vertical line underground writing line 16 as a joint pattern along the shape of the joint layer 6 (whether curved or inclined). Then, the drawing position of the horizontal line underground writing line 17 is determined, and a mark is set at the position to be the drawing origin of the draft line. In general, marks are drawn with ink, paint, or the like on the end side of the construction area and the other end side opposite thereto. Next, when a yarn 18 soaked in pigment or ink is placed along the mark, and a portion of the yarn 18 is slightly pulled and tensioned from both ends, a portion of the yarn 18 is flipped with a tiptoe. The yarn 18 collides and the adhered pigment or the like falls on the joint layer 6, and the vertical joint underground writing line 16 and the horizontal joint underground writing line 17 which are drafts of a predetermined joint pattern are drawn.

  Subsequently, in the “longitudinal joint form attaching step”, as shown in FIG. 5, the vertical member 9 a is attached onto the joint layer 6. Specifically, the vertical member 9a is arranged along the vertical underground writing line 16, and the adhesive protective tape 10 (see FIG. 3) attached to the foam layer 12 constituting the vertical member 9a is peeled off to adhere The layer 11 is pressed onto the vertical grid line 16 (or in the vicinity; see the dashed line portion in FIG. 5) and stuck onto the joint layer 6. Then, if the construction area is 5 m × 3 m, for example, it is cut at a length of about 5 m. Thus, the vertical member 9 a is disposed on the joint layer 6.

  Next, in the “horizontal joint form sticking step”, the horizontal member 9b is arranged along the horizontal joint underground writing line 17 (see the two-dot chain line portion in FIG. 5), cut into a predetermined length, and then an adhesive protective tape. 10 (see FIG. 3) is peeled off from the adhesive layer 11 and stuck onto the joint layer 6. Here, the “predetermined length” in the horizontal member 9b indicates a state where the horizontal member 9b is divided into a length substantially equal to the inner dimension of the adjacent vertical member 9a. More specifically, when the vertical member 9a having a width of 10 mm is disposed on the joint layer 6 at an interval of 300 mm, a state in which the horizontal member 9b is divided by a length of 290 mm, or the like can be given. . In this way, the transverse member 9b is disposed on the joint layer 6. The interval amount is not limited to this numerical value, and can be appropriately changed according to construction specifications. Further, the order of the step of peeling the adhesive protective tape 10 from the plurality of vertical members 9a and the horizontal members 9b and the step of cutting the vertical member 9a or the horizontal member 9b to a predetermined length is not limited to this, but reverse It may be a simultaneous progress. However, as in this example, when the vertical member 9a is first disposed, and then the horizontal member 9b is disposed, the inner dimension of the vertical member 9a is slightly changed due to the shape change of the base layer 2 such as curvature or inclination. Even in this case, it is easy to divide the horizontal member 9b so as to have a length substantially equal to the inner dimension, and between the vertical member 9a and the horizontal member 9b in a state of being stuck on the joint layer 6. It is difficult to form a gap, which is more preferable.

  FIG. 6 schematically shows a state in which the vertical member 9a and the horizontal member 9b are attached and disposed on the joint layer 6 in the “vertical joint form attaching step” and the “horizontal joint form attaching step”. It is a cross-sectional schematic diagram shown in FIG. In the “horizontal joint form linking step”, as shown in FIG. 6A, first, the adhesive protective tape 15 of the horizontal member 9b arranged in the same row D (FIG. 7, one-dot chain line portion; the same applies hereinafter) is peeled off. . Then, the connecting sheet 19 is attached to the exposed surface of the adhesive layer 14, and the divided transverse members 9b are integrally connected (FIG. 6B). At this time, the connecting sheet 19 is disposed on the surface H of the vertical member 9a at the intersection between the vertical member 9a and the horizontal member 9b, but the horizontal member 9b is not provided with an adhesive layer on the surface H. Only is attached to the connecting sheet 19 and connected. The connecting sheet 19 is preferably relatively thin and flexible. For example, a sheet-like object having a thickness of 2 mm or less and a width of about 10 mm (a shape substantially equal to the joint mold member 9) is exemplified. it can.

  Next, in the “surface layer material application step”, a resin mortar using MMA resin as a binder is created and applied to the joint layer 6 to which the joint form member 9 is attached. The blending ratio of the resin mortar is not particularly limited. For example, when the ground temperature is 10 ° C., the MMA resin is approximately 5 kg and the aggregate is approximately 10 kg. Then, as shown in FIG. 7, the prepared resin mortar is filled in the substantially quadrilateral closed region R divided by the vertical member 9a and the horizontal member 9b, and the surface thereof is boiled flat with a rivet 20 or the like. To do. At this time, the surface layer material 7 having a uniform thickness is formed by leveling the joint mold member 9 so as to have a height substantially equal to the thickness of the joint form member 9. Since the surface layer material 7 of this example contains a wax, a wax having a relatively low specific gravity as compared with a resin or the like floats near the surface of the surface layer material 7 to form a film. For this reason, the inside of the surface layer material 7 is shielded from oxygen in the atmosphere, the polymerization reaction of the MMA resin is not inhibited, and curing proceeds rapidly.

  Then, in the “horizontal joint form peeling step”, as shown in FIG. 8, the connecting sheet 19 is pulled upward from the end side of the construction region, and the horizontal member 9 b is peeled from the joint layer 6. Here, as described above, only the lateral member 9b is adhered to the connecting sheet 19 by the adhesive layer 14 and the longitudinal member 9a is not adhered, whereby the lateral member 9b disposed in the same row D is provided. Only the chain will peel off. Then, the horizontal members 9b in the other rows are similarly peeled off, and all the horizontal members 9b are peeled off. In this step, the lateral member 9b located on the inner side of the construction region can be peeled by gripping one end side of the connecting sheet 19 from the outside (end side) of the construction region and pulling it upward. That is, the inner side lateral member 9b can be peeled without the operator entering the inner surface I (see FIG. 7) of the construction area. Therefore, after applying the surface layer material 7 in the closed region R of the entire surface of the construction area in the “surface layer material application step”, this process and the “longitudinal joint formwork peeling” described later can be performed without waiting for the surface layer material 7 to completely cure. It is possible to shift to “Process”.

  Subsequently, in the “longitudinal joint form peeling step”, as shown in FIG. 9, the plurality of vertical members 9 a are peeled off from the joint layer 6 (see FIG. 8, hereinafter the same). Basically, the procedure is the same as the procedure for peeling the connected horizontal member 9b, and a known tool such as a pin vise or a cone is inserted into the end of the vertical member 9a so as to protrude from the joint portion 4 and start out. The end of the vertical member 9a is lifted upward to peel off from the joint layer 6.

  Here, as already shown in FIGS. 2 and 3, there are a large number of voids K in the foamed layer 12 constituting the vertical member 9a and the horizontal member 9b. Further, since the wax blended in the surface layer material 7 has a relatively low specific gravity, it mainly floats to the vicinity of the surface H of the surface layer material 7, and the contact portion (joint portion) between the foam layer 12 and the surface layer material 7. 4) It is difficult to form a film in the vicinity. For this reason, the gap K and the surface layer material 7 are easily in direct contact with each other without passing through the wax film, the oxygen in the gap K inhibits the polymerization reaction of the MMA resin, and the surface layer material 7 of the joint portion 4 is cured. It is difficult. Therefore, for example, even if the construction area is relatively wide and the surface layer material 7 may be cured to some extent during the peeling work of the joint form member 9, the end surface portion of the surface layer material 7 located at the joint portion 4 is The vertical member 9a and the horizontal member 9b can be smoothly peeled while being kept in a relatively soft state.

  And the protective film 8 is apply | coated to the surface of the surface layer material 7 and the joint part 4 (refer FIG. 2) from which the joint mold member 9 was peeled. The protective film 8 is applied using an appropriate tool such as a roller, a brush, a scissors, or a spray gun. In this way, the pavement layer 1 having a plurality of tile pattern portions 3 as shown in FIG. 1 is completed.

  As described above, according to the pavement method of this example, the horizontal joint formwork connecting step is performed before the surface layer material application step, so that the construction can be performed without entering the surface of the applied surface material 7. The lateral member 9b located on the inner side can be peeled from the outer side of the region. Therefore, since the vertical member 9a and the horizontal member 9b can be quickly peeled off from the joint layer 6 without waiting until the surface layer material 7 is completely cured, the surface layer material 7 and the joint form frame member 9 are fixed. It is difficult to peel off smoothly. In addition to being able to peel smoothly, the working efficiency is increased, and the transverse member 63 that cannot be peeled off may be broken off and remain on the joint, or the tile pattern portion 3 may be caught by a part of the surface layer material 7. The possibility of causing a peeling failure such as chipping is reduced, and the pavement layer 1 having a high design property can be provided.

  Furthermore, according to the pavement method of this example, the cross member 9b is connected by using the connecting sheet 19. Therefore, not only is the connecting operation simple, but there is no possibility that a step or the like is generated in the connecting portion to obstruct the surface layer material coating process. Moreover, according to the pavement method of this example, a plurality of horizontal members 9b can be peeled at a time without securing a work space by assembling a scaffold or the like. For this reason, a more rapid and economical pavement method can be provided. Moreover, by applying the rod-shaped joint form member 9, the base layer 2 is curved or inclined, and walls, columns, and obstacles (ash trays, benches, vending machines, etc.) ), It is possible to quickly and economically form joint patterns according to the situation of the construction site without creating a dedicated joint form member. Moreover, since the vertical member 9a and the horizontal member 9b can be peeled separately from each other from the joint layer 6, the vertical member 9a and the horizontal member 9b do not get stuck in the corners of the tile pattern portion 3 and cause poor peeling. Therefore, there is little possibility of reworking due to poor peeling, and an economical pavement method can be provided.

  Moreover, by applying the resin mortar which uses MMA resin as the binder to the surface layer material 7, it can be cured very quickly and the construction time can be shortened. Furthermore, since MMA resin is excellent in weather resistance and abrasion resistance, it can be used without repair for a long period of time, and is extremely economical. Moreover, according to the pavement method of this example, the joint formwork member 9 which comprises the foaming layer 12 is applied. For this reason, the surface layer material 7 and the joint form frame member 9 are hard to adhere and can be peeled off smoothly. Furthermore, since the surface layer material 7 of this example is blended with wax, the surface of the surface layer material 7 is hard to come into contact with air and hardens quickly. For this reason, construction time can be shortened and it is effective. Moreover, according to the pavement method of this example, the joint form member 9 and the connecting sheet 19 are composed of a sheet-like object having flexibility, and therefore it is relatively easy to carry in and store at the construction site. Also, when peeling from the joint layer 6, it can be flexed freely and is excellent in workability and effective.

  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, as shown in FIG. 3, although what used the vertical member 9a which comprises the protective tape 13 on the surface H side, and the horizontal member 9b which comprises the adhesion layer 14 and the adhesion protective tape 15, was illustrated, It is not limited to this configuration. For example, the vertical member 9a and the horizontal member 9b may be shared, and a joint form member having the adhesive layer 14 and the adhesive protective tape 15 on the surface H side may be used. In this case, the joint form frame member 9 arranged in the vertical direction performs the horizontal joint form sticking process and subsequent steps without peeling off the adhesive protective tape 15. According to this configuration, the required joint form member can be simplified in common, which is more preferable.

  In the said embodiment, although what mix | blended MMA resin, a wax, and an aggregate was illustrated in the surface layer material 7, it is not limited to this structure, It is good also as a structure which does not mix | blend a wax. In addition to the above-mentioned blending, a known thixotropic agent may be blended. According to this, when the surface layer material 7 is applied and the joint form frame member 9 is peeled off in the vertical (horizontal) joint form frame peeling step, the surface layer material 7 is difficult to drip and is relatively stable. The shape is retained. Therefore, construction can be completed quickly, which is preferable.

  Moreover, in the said embodiment, although what formed the smooth layer 5 and the joint layer 6 only once in the base layer application | coating process was illustrated, it is not limited to this structure. For example, the coating operation of the smooth layer 5 and the joint layer 6 may be performed a plurality of times, or only the smooth layer 5 or only the joint layer 6 may be applied.
