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 joint form member (uneven pattern forming member) obtained by casting a joint pattern as shown in Patent Document 1 is also known. Specifically, the concavo-convex pattern forming member is fixed to the surface of the wall surface base that has been smoothed, and the spraying material is filled into the punched portion formed in the concavo-convex pattern forming member. And the uneven | corrugated pattern formation member is peeled from a wall surface base | substrate in the state which the spraying material fully dried and solidified. Thereby, a pavement surface having a pavement layer having the same shape as the plurality of punched portions and a joint pattern having the same shape as the uneven pattern forming member formed between the pavement layers is formed. By using such a pavement method, a pavement surface having a grid-like joint pattern can be formed relatively easily without laying a large amount of bricks one by one.

  By the way, the joint mold member as described above (hereinafter referred to as “form member”) is created by punching a synthetic resin material or the like into a predetermined joint pattern using a known punching machine or the like. . Therefore, it is necessary to design and determine the punching shape in advance, perform punching molding at a factory, etc., and then carry the created formwork member to the site. At this time, if the design and the situation at the actual construction site (inclination of the construction surface, curved shape, arrangement of obstacles such as walls and pillars) are different, the desired joint pattern cannot be formed, Since it is necessary to recreate the formwork member, there is a problem that the cost increases and the construction period increases. In addition, when the construction area is relatively large, it is divided into several small construction areas, but this is necessary depending on the shape of the construction surface and the position of the obstacle in each construction area. Since the shape of the formwork member is different, it is necessary to separately design a large number of formwork members separately, and there is a problem in that economic efficiency is reduced and the burden of member management is increased.

  Therefore, a pavement method using a rod-shaped joint mold member 60 as shown in FIG. 12A instead of the joint mold member formed in a lattice frame shape has been proposed. Specifically, among the grid-like joint pattern, the vertical member 62 of a rod-shaped joint form frame member that forms a joint portion in a predetermined direction (vertical direction), and substantially perpendicular to the vertical member 62 This is a method of forming the joint form member 60 with the transverse member 63 which is arranged in the direction to form the joint portion in the lateral direction. According to this method, at the construction site, the vertical member 62 and the horizontal member 63 can be appropriately arranged while checking the shapes of various construction surfaces and the arrangement of obstacles, so that the design can be changed flexibly. Can be efficient. Moreover, it is not necessary to create a form member individually designed as described above, and it is only necessary to manage the vertical member 62 and the horizontal member 63, so that the management burden of the member can be reduced and the economy can be improved. Contribute.

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. 12A) in a state where such a gap S is generated, the surface layer material enters the gap S to realize a desired rectangular shape (tile pattern). This is not preferable because it may not be possible. Therefore, in order to suppress the generation of the gap S, it is widely performed that the horizontal member 64 is divided at a predetermined interval in accordance with the interval between the adjacent vertical members 62.
No. 04-15484

  By the way, it is common that the peeling process which peels the joint mold member 60 is performed before the apply | coated surface layer material 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 60, the surface layer material and the joint form frame member 60 are fixed, and it becomes difficult to smoothly peel the joint form frame member 60. Because. At this time, as shown in FIG. 12 (a), the vertical member 62 has a single continuous shape in the vertical direction, and therefore, one end side of the vertical member 62 from the surface of the underlayer from the outside of the construction area. By peeling and pulling upward, the other end can be peeled 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, if the peeling is performed from the outside of the construction area as in the case where the longitudinal member 62 is peeled, it is not possible to peel from one end side to the other end side at a time. In particular, the lateral member 63 located on the inner side of the construction area was invaded into the construction area (that is, riding on the surface layer material) and divided using a known tool such as a cone or an iron skewer. It is necessary to roll off the horizontal members 63 one by one from the gaps in the surface layer material. At this time, it is necessary to sufficiently harden the surface layer material so that the surface layer material is not scratched or distorted even if the operator gets on the surface layer. The material and the horizontal member 63 are fixed, and it takes a lot of time and effort for the operator.

  In addition, there is a problem that the transverse member 63 that cannot be peeled off is cut off and remains in the joint portion, which deteriorates the appearance of the pavement layer. Furthermore, if the transverse member 63 is forcibly pierced from the gap of the surface material, that is, the joint, the tip of the tool may collide and scratch the surface material, and the tile pattern may be chipped. It was time consuming and inefficient because work had to be done.

  Then, this invention makes it a subject to provide the pavement method which makes the joint form peeling process efficient, and is excellent in design property and economical efficiency in view of said actual condition.

  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. A pavement method for forming a pavement layer having a grid-like joint pattern, the vertical layer underground writing line serving as a guideline for the vertical joint pattern on the surface of the base layer, and the guideline for the horizontal joint pattern, A draft line drawing step for drawing a horizontal line underground writing line, and the vertical joint formwork member, at least adjacent to the intersection portion disposed at the intersection of the vertical grain underground writing line and the horizontal line underground writing line A flip-up member attaching step for attaching a flip-up member that flips up an end of one horizontal joint form frame member, and a bar-like vertical joint form frame member on the surface of the base layer along the vertical line underground writing line. A stick-shaped horizontal joint mold member that exhibits a length substantially equal to the inner dimension of the adjacent vertical joint mold member and has a thickness substantially equal to that of the vertical joint mold member. A horizontal joint form frame sticking step for sticking to the surface of the foundation layer along the horizontal joint underground line, and the vertical joint form frame member and the horizontal joint form frame member on the surface of the foundation layer. A surface layer material application step for applying a liquid surface material so as to be substantially equal to the thickness, and in a state where the surface of the surface material is substantially cured, the vertical joint form frame member is peeled off from the surface of the base layer. The horizontal joint formwork stripping step from the surface of the base layer after the vertical joint formwork stripping step of flipping up the end of the horizontal joint formwork member via the flip-up member and the vertical joint formwork member stripping step And the Yokome local frame peeling process for peeling the member. "

  Here, “drawing a draft line” refers to an operation of creating a mark that serves as a guideline for the position where the joint formwork member is adhered to the surface of the underlayer, and includes a thread soaked in ink or graphite or white lime. For example, an operation of drawing the sticking position on the surface of the underlayer using an appropriate drawing means such as powder. “Splashing up” means that the end portion of the horizontal joint member is peeled off from the surface of the base layer and pulled upward, and is picked up from the gap between the plurality of surface layer members formed in a grid pattern, that is, from the joint portion. Indicates the status to be issued. On the other hand, the shape of the “bounce-up member” is not particularly limited, and may be any shape such as a circle or a regular polygon, but is thinner than the thickness of a relatively thin material such as a joint formwork member. When the surface material is applied in the “surface layer material application step”, the level difference generated at the location where the flip-up member is attached is reduced, and the application operation is not hindered.

  Further, “attaching” indicates a state of attaching to the vertical joint form frame member using a predetermined fixing method, for example, an appropriate fixing means such as adhesion, sewing, embedding, and locking. The “attachment” location may be any part of the vertical joint formwork member disposed at the intersection (hereinafter simply referred to as “intersection”) between the vertical underground writing line and the horizontal underground writing line. A place may be sufficient, for example, the case where it attaches to the intermediate | middle layer between the surface side of a vertical joint formwork member, a back surface side, a surface, and a back surface etc. can be illustrated. 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, “sticking” means that a vertical (horizontal) joint form frame member is disposed on the surface of the base layer and can be peeled off from the surface of the base layer in the subsequent vertical (horizontal) joint form frame peeling step. A state of temporary fixing to a certain extent is shown. For example, the joint mold member is fastened to the base layer with a small scissors, an adhesive substance such as glue is applied to the surface of the base layer, or the back side of the joint mold member (the side to be bonded to the base layer) ) And the like. The “substantially cured state” indicates that the surface layer material includes not only a completely cured state but also a state in the middle of curing (a so-called semi-cured state). Further, the “intersection placement position” indicates a vertical member at a position located near the intersection of the vertical underground writing line and the horizontal underground writing line when the vertical member is arranged along the vertical underground writing line. .

  Therefore, according to the pavement method of the present invention, the flip-up member for flipping up the end of the horizontal joint form member (hereinafter, simply referred to as “transverse member”) is used as the vertical joint form member (hereinafter, simply “ A vertical member). Thereby, in the vertical joint form peeling process, when the vertical member is peeled off from the surface of the base layer, the end portion of the horizontal member can be pulled up together via the flip-up member, and can be pierced from the joint portion. it can. In addition, the shape of the flip-up member is not particularly limited, and any member can be used as long as it is attached to the position where the vertical member intersects and raises at least one end of the adjacent horizontal member. However, it is particularly preferable that the two lateral members can be peeled off more efficiently if both ends of the adjacent lateral members are flipped up.

  By the way, in the above-mentioned pavement method, when the flip-up member is arranged on the surface of the vertical member, the tool is applied to the flip-up member when the surface layer material is applied using a tool such as a scissors in the surface layer material application step. May be caught and smooth application work may be hindered. In view of this problem, in the pavement method of the present invention, “the flip-up member is a first member disposed along the longitudinal direction of the vertical joint form member and the longitudinal direction of the horizontal joint form member. The first member is disposed on the back side of the vertical joint mold member, and has an adhesive layer at a portion in contact with the vertical joint mold member. Can be. "

  Therefore, according to the pavement method of the present invention, since the flip-up member is attached to the back side of the vertical member, it is not exposed to the front side of the vertical member, and it does not interfere with the coating operation in the subsequent surface layer material coating process. Is. Furthermore, when the flip-up member is attached to the back side of the vertical member, the adhesive state between the flip-up member and the vertical member is released when the vertical member is peeled from the surface of the underlayer in the vertical joint form peeling process. That is, the flip-up member may fall off from the back side of the vertical member, but according to the pavement method of the present invention, the flip-up member includes the adhesive layer, so that the vertical member and the flip-up member Can be firmly bonded, and there is no fear that the flip-up member falls off from the back side of the vertical member. Thereby, it becomes possible to reliably flip up the end portion of the transverse member via the flip-up member, and the ends of the plurality of transverse members can be more efficiently pierced from the gaps in the surface layer material. The stripping operation of the horizontal member is further simplified.

  On the other hand, in the above-mentioned pavement method, when the flip-up member is arranged on the front surface or the intermediate layer (layer between the front surface and the back surface) of the horizontal member, it may be considered that the end of the horizontal member does not jump up well. In particular, when the transverse member is a relatively soft material having flexibility, only the bonding surface (surface or intermediate layer) with the flip-up member is pulled upward, that is, only a part is torn and broken. For example, there may be a case where most of the remaining transverse members remaining on the joint remain in the joints. When such a problem occurs frequently, it is not possible to smoothly proceed to the horizontal joint form peeling work, which is not preferable.

  Therefore, in view of the above-described problem, the present invention provides that “the flip-up member includes a first member disposed along a longitudinal direction of the vertical joint form member and a longitudinal direction of the horizontal joint form member. The second member is disposed on the back surface side of the end portion of the horizontal joint form frame member.

  Therefore, according to the pavement method of the present invention, since the end of the horizontal member is flipped up from the back side by the flip-up member, there is no fear of tearing off from the surface or the intermediate layer, neatly from the joint part It is worn out. Therefore, only a part of the transverse member is cut off and pulled up together with the longitudinal member, and there is no fear that most of the other transverse members remain in the joint part, and the end part of the transverse member is efficiently removed from the joint part. Since it can be worn out, it is effective.

  In the pavement method of the present invention, “the flip-up member has a width substantially equal to or narrower than a width of the vertical joint form member, and is disposed along a longitudinal direction of the vertical joint form member. A first member and a second member having a width substantially equal to or narrower than the width of the horizontal joint form frame member and extending from the first member along the longitudinal direction of the horizontal joint form frame member In the step of attaching the flip-up member, the first member is disposed along the vertical underground line, and the second member is disposed along the horizontal underground line. It is characterized by "

  Therefore, according to the pavement method of the present invention, the vertical member and the horizontal member have substantially the same or narrow width, and a flip-up member having a cross shape arranged along the vertical member and the horizontal member is used. Compared with the case where a flip-up member having a shape such as a circle or a quadrangle is used, there is less possibility that a part of the surface layer material is chipped in the vertical (horizontal) joint mold peeling process. Specifically, for example, when the surface layer material is applied in the surface layer material application step after the circular spring members are disposed at the intersections, the spring member protrudes from the end surface of the vertical member or / and the horizontal member. The surface material is applied to the surface of the protruding member that protrudes. In such a state, when the vertical member is peeled from the surface of the base layer, the surface layer material applied to the surface is pulled upward together with the vertical member, and the corners of the surface layer material formed in a rectangular shape, etc. It may be possible to lack the. However, according to the paving method of the present invention, the flip-up member has a width equal to or less than that of the vertical (horizontal) member, and has a cross shape along the vertical member and the horizontal member located at the intersection. Thus, a part of the flip-up member can be attached without protruding from the end surfaces of the vertical member and the horizontal member. Therefore, the end portion of the horizontal member can be efficiently pierced without losing a part of the surface layer material, and the horizontal joint form peeling process is more efficient. Can be provided.

  Moreover, according to the pavement method of the present invention, since the flip-up member has a cross shape, the central portion of the flip-up member can be easily confirmed. Therefore, even when the flip-up member is attached before the vertical member and the horizontal member are attached to the surface of the base layer in the flip-up member attaching step, the center portion of the flip-up member and the approximate center of the intersecting portion are Since it is easy to visually confirm and align and arrange, the mounting position of the flip-up member is difficult to shift. Therefore, it is difficult for the flip-up member to protrude from the end face of the vertical (horizontal) member, and there is less risk of the surface layer material being chipped in the vertical (horizontal) joint mold release process. It becomes possible to provide.

  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 composed of a resin mortar and is characterized by being mixed with wax.

  Here, the “wax” refers to an ester of a fatty acid and a monohydric or dihydric alcohol, and examples thereof include a paraffin wax obtained by separating and extracting hydrocarbons having good crystallinity from a vacuum distillation distillate portion of crude oil. The “foamed layer” is not particularly limited as long as it is a material having bubbles inside, and examples thereof include a foamable polyurethane resin and a foamable polyethylene resin.

  Therefore, according to the pavement method of the present invention, a methyl methacrylate monomer resin (hereinafter, simply referred to as “MMA resin”), which tends to slow the curing reaction when contacted with air, is applied to the surface layer material and has a foam layer. Since the transverse member to be used is used as a joint form frame member, the curing reaction of the surface layer material in contact with the transverse member (that is, the surface layer material of the transverse joint portion) is slowed, and a relatively soft state is maintained for a long time. On the other hand, because the MMA resin contains a wax, the wax having a lighter specific gravity than the surface material floats near the surface of the surface material, and forms a film between the surface side of the surface material and the outside air. . Therefore, since the surface side of the surface layer material is difficult to come into contact with oxygen and the curing reaction is not hindered, the curing proceeds rapidly to a hardness that does not cause scratches or distortion even if the operator rides on the surface of the surface layer material. As a result, before the surface layer material of the horizontal joint portion is cured, that is, before the horizontal member and the surface layer material are fixed, they enter the construction area and easily peel the lateral member located on the inner side of the construction area. Therefore, more efficient construction can be realized. In addition, since a resin mortar having MMA resin as a binder is applied as a surface layer material, various features of MMA resin, such as high mechanical strength, compared to the case of using general hydrating cement concrete, etc. A pavement layer that enjoys excellent properties such as water resistance, wear resistance, high electrical insulation, and chemical resistance can be provided, and a more economical pavement method can be provided.

  As described above, according to the paving method of the present invention, it is not necessary to pierce the plurality of divided transverse members one by one from the joint portion, and the end portion of the transverse member can be jointed only by peeling the longitudinal member. Therefore, it is possible to effectively reduce the work time and labor required for peeling the horizontal joint form frame member. In addition, since it is possible to efficiently pierce the horizontal joint form frame member, it is not necessary to forcibly pierce using a tool, and the surface layer material is hardly damaged, so that a paving method with high design can be provided. . Furthermore, since it is possible to pull up the end of the horizontal member bounced up by the bounce-up member and peel it off from the surface of the underlayer, compared with the case of piercing with a sharp tool (cone, iron skewer, etc.) There is little possibility that a part of the horizontal member is broken and remains in the joint portion, and a pavement layer having a high design property can be provided more easily.

  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. 3 is an enlarged cross-section of a joint mold member 4 is a perspective view showing a flip-up member, FIG. 5 is an explanatory view showing a draft line drawing step, and FIG. 6 is a flip-up member attaching step, a vertical joint form attaching step, and a horizontal eye. FIG. 7 is a perspective view showing a surface layer material application process, FIG. 8 is an explanatory view showing a vertical joint form frame member peeling process, and FIG. 9 is a vertical joint form. It is a perspective view which shows the pavement layer of the state which the frame peeling process was complete | finished, and FIG. 10 is explanatory drawing which shows a horizontal joint form frame 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 up by smoothing relatively small irregularities existing on the base layer 2, and publicly known concrete such as asphalt concrete and cement concrete can be applied. In this example, resin mortar is applied. Has been. In addition, concrete indicates a mixture in which a binder and an aggregate are mainly blended, and resin mortar uses a resin as a binder and only a relatively fine aggregate having a particle size of 5 mm or less. A type of concrete. 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 mold member 9 as shown in FIGS. 3 and 6 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, the joint mold member 9 includes an adhesive protective tape 10, an adhesive layer 11, a foamed layer 12, and a protective tape 13, as shown in FIG. 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 used to stick and temporarily fix 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 joint mold member 9, and the foam layer 12 and the surface layer material 7 are fixed. , Provided on the surface H side of the joint formwork member 9. 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 joint form member 9 is a rod-like member having a thickness of about 2 mm and a width of about 10 mm as a whole, and a construction site in a state where an appropriate length (several tens of meters, etc.) is wound in a ring shape. It is conveyed to. And it functions as the vertical member 9a or the horizontal member 9b by cut | disconnecting to predetermined length and sticking on the joint layer 6. FIG.

  Further, in the pavement method of this example, a flip-up member 14 as shown in FIG. 4 is used as means for jumping up the end of the horizontal member 9b. The flip-up member 14 is a member that is attached to the vertical member 9a and that flips up the end of the horizontal member 9b in the vertical joint form peeling process. For example, aluminum, iron, hard vinyl chloride resin, polyethylene resin, polypropylene It is more preferable to apply a material that has a certain degree of hardness and toughness and is lightweight in a relatively thin state, such as a resin or a polybutene resin. The flip-up member 14 is a substantially cross-shaped member composed of a first member 15 disposed along the vertical member 9a and a second member 16 disposed along the lateral member 9b.

  More specifically, the first member 15 is a strip-like object having a thickness of about 0.5 mm, a length L in the major axis direction of about 50 mm, and a width W substantially equal to that of the vertical member 9a. An adhesive layer 17 is formed on a surface that contacts the vertical member 9a (hereinafter referred to as “the surface of the flip-up member 14”). The second member 16 is formed to extend from a substantially central portion of the length L of the first member 15 in a direction substantially perpendicular to the first member 15, that is, in a direction arranged along the horizontal member 9 b. It has substantially the same thickness, length in the major axis direction, and width, and the adhesive layer 17 is not provided. Note that the shape of the flip-up member 14 is not limited to this, and any shape may be used as long as it is a circle, a regular polygon, or any other shape that can flip up the lateral member 9b (details will be described later). However, it is more preferable to apply a relatively thin material, for example, a material thinner than the thickness of the joint formwork member 9, because the work efficiency in the surface layer material coating process described later is not hindered. Further, the length L and the width W in the major axis direction of the first member 15 and the second member 16 are not limited to the above-mentioned numerical values, but other sizes can naturally be applied. If the value of the width W is at least smaller than the width of the vertical member 9a (or the horizontal member 9b), there is little risk of missing a part of the surface layer material 7 in the vertical (horizontal) joint mold release process. Is effective.

  Then, the pavement method of this invention is demonstrated. The pavement method of the present invention has seven steps, namely, “draft line drawing step”, “bounce-up member attaching step”, “vertical joint form attaching step”, “horizontal joint form attaching step”, “surface layer material” It can be broadly divided into “application process”, “longitudinal form peeling process”, and “horizontal joint form peeling process”.

  First, a base layer serving as a base when the joint mold member 9 is attached is formed on the surface of the base layer 2. 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, the periphery of the base layer 2 is covered with a vinyl sheet, and measures are taken to prevent scattering of paint and the like (so-called “curing”). Then, a resin that is a binder and an aggregate are blended to create a resin mortar, which 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, a resin mortar colored by blending a resin, a pigment, and an aggregate is prepared, and the resin mortar is uniformly applied to the surface of the smooth layer 5, whereby a joint layer is formed on the surface of the smooth layer 5. 6 is formed. 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 is exposed from between the plurality of tile pattern parts 3 after the joint form member 9 is peeled from the joint layer 6 in the “vertical joint form peeling process” and “horizontal joint form peeling process” described later. It is desirable to color a color contrasting with the color of the surface layer 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. 5, using a known surveying instrument or laser marking device, as a draft of a joint pattern along the shape of the joint layer 6 (presence or absence of curvature, inclination, etc.) The drawing positions of the line 18 and the horizontal underground writing line 19 are 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 the yarn 20 soaked in pigment, ink, or the like is arranged along the mark, and the yarn 20 is lightly pulled from both ends and is strained, a part of the yarn 20 is flipped with a toe, and then on the joint layer 6. The yarn 20 collides and the attached pigment or the like falls on the joint layer 6, and the vertical grain underground writing line 18 and the horizontal mesh underground writing line 19 which are drafts of a predetermined joint pattern are drawn.

  Next, in the “bounce-up member attaching step”, as shown in FIG. 6, the bounce-up member 14 is disposed at the intersection B between the vertical underground writing line 18 and the horizontal underground writing line 19. At this time, when the intersecting center portion C (see FIG. 4) of the first member 15 and the second member 16 of the flip-up member 14 and the intersecting portion B are arranged so as to overlap each other, the joint mold member 9 can be seen. Since the spring-up member 14 does not protrude from the end face of the joint formwork member 9 when it is stuck on the formation 6, it is more preferable. Note that the flip-up member 14 of this example is provided with an unillustrated adhesive layer on the surface that is in contact with the joint layer 6 (hereinafter referred to as the “back surface of the flip-up member 14”). As the adhesive layer, one having an adhesive strength weaker than the adhesive strength of the adhesive layer 17 provided on the surface side is applied. This is because it is considered that the flip-up member 14 can be smoothly peeled together with the vertical member 9a in the “longitudinal joint form peeling step” described below, and by providing such an adhesive layer, The flip-up member 14 disposed on the joint layer 6 can be temporarily fixed so as not to be easily displaced by wind or the like, and the workability in the subsequent “vertical (horizontal) joint form attaching step” is improved.

  Subsequently, in the “longitudinal joint form pasting step”, the longitudinal member 9 a is stuck on the joint layer 6. Specifically, as shown in FIG. 6, the adhesive protective tape 10 provided on the back surface R side of the joint mold member 9 (see FIG. 3, the same applies hereinafter) is peeled off, and the adhesive layer 11 is replaced with the joint layer 6. The foam layer 12 is stuck along the vertical underground writing line 18. Therefore, the back surface R side of the joint form frame member 9 abuts on the surface side of the first member 15 of the flip-up member 14, and the first member 15 is adhered in a state where the joint form frame member 9 covers the first member 15. . And the joint mold member 9 is cut | disconnected by predetermined length along the area of a construction area | region, and the vertical member 9a is formed.

  Then, in the “horizontal joint form sticking step”, the horizontal joint 9 b is attached onto the joint layer 6. Specifically, the adhesive protective tape 10 provided on the back surface R side of the joint mold member 9 is peeled off and the adhesive layer 11 is pushed onto the joint layer 6 in the same manner as in the “vertical joint mold attachment process”. The foam layer 12 is adhered along the horizontal line 19 in the horizontal direction. The horizontal member 9b is divided into a predetermined length, that is, a length substantially equal to the inner dimension of the adjacent vertical member 9a, and is stuck on the joint layer 6. For example, when the vertical members 9a having a width of 10 mm are disposed on the joint layer 6 at intervals of 300 mm, a state in which the horizontal members 9b are divided and pasted every 290 mm in length can be exemplified. In addition, the above-mentioned interval amount is not limited to this numerical value, and can naturally be changed as appropriate 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.

  Next, in the “surface layer material application step”, a resin mortar using MMA resin as a binder is created and applied onto the joint layer 6 to which the vertical member 9a and the horizontal member 9b are 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 created resin mortar is filled in the substantially quadrilateral closed region R divided by the vertical member 9 a and the horizontal member 9 b, and the surface thereof is boiled flat with a rivet 21 or the like. To do. At this time, the vertical member 9a and the horizontal member 9b are formed with substantially the same thickness, the horizontal member 9b is divided, there is no portion overlapping the vertical member 9a, and the flip-up member 14 is relatively thin. By using this member, the surface layer material 7 having a uniform thickness is relatively easily and reliably formed. Further, since the surface layer material 7 of this example contains a wax, the wax having a specific gravity lower than that of the 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 “longitudinal joint form peeling step”, the plurality of vertical members 9 a are peeled off from the joint layer 6. Specifically, a known tool, such as a cone or an iron skewer, was pierced into the vertical member 9a, and the vertical member 9a located on the end side of the construction area was pierced from the joint portion 4 and pierced. The vertical member 9a is peeled off from the joint layer 6 by pulling upward.

  FIG. 8 is a diagram schematically showing a cross section of the vertical member 9 a and the horizontal member 9 b in the “vertical joint form peeling process”. FIG. 8A shows a state before the vertical member 9 a is peeled from the joint layer 6. FIG. 8B shows the state after peeling. As shown in FIG. 8 (a), by passing through the “bounce-up member attaching step”, “vertical joint form attaching step”, and “horizontal joint form attaching step”, the back side of the vertical member 9a A first member 15 is disposed, and a second member 16 is disposed on the back side of the transverse member 9b. In such a state, when the vertical member 9a is pulled upward and peeled off from the joint layer 6, the second member 16 pushes up the end of the horizontal member 9b as shown in FIG. 8B. Thereby, the edge part of the horizontal member 9b will be peeled off from the joint layer 6, and will be in the state rolled up upwards (refer FIG. 9).

  Here, MMA resin is blended in the surface layer material 7 and the longitudinal member 9a includes the foamed layer 12 (see FIG. 2; the same applies hereinafter), so that the inside of the surface layer material 7 is rapidly cured. However, the contact portion between the foam layer 12 and the surface layer material 7, that is, the surface layer material 7 located in the joint portion 4 is slowed down by the oxygen contained in the gap K. Therefore, since the vertical member 9a and the surface layer material 7 are difficult to adhere, the peeling operation can be performed smoothly.

  Then, in the “horizontal joint form stripping step”, as shown in FIG. 9, the end portion T of the horizontal member 9b pierced from the joint portion 4 is picked up and pulled up, and the horizontal member 9b is pulled up. The whole is peeled off from the joint layer 6. Similarly to the vertical member 9a, the horizontal member 9b also includes the foamed layer 12, so that the surface layer material 7 is difficult to adhere and can be easily peeled off. Further, since the surface layer material 7 is blended with wax, a wax film is formed on the surface I, and the curing reaction proceeds relatively quickly. In other words, the surface layer material 7 located at the joint portion 7 is maintained in a soft state and the surface I and the surface layer material 7 on the inner side are quickly cured, so that the operator enters the inside of the construction area at an early stage. Thus, the lateral member 9b can be peeled off, which contributes to further efficiency of the construction work.

  Moreover, since the end part T of the horizontal member 9b can be pinched and peeled off, it can be peeled off more smoothly and reliably. For example, when peeling starts from the center of the horizontal member 9b, as shown in FIG. 10A, when the operator pulls the horizontal member 9b upward with the force F, the force F is doubled, that is, The force F1 and F2 are dispersed and applied to the transverse member 9b. On the other hand, in the present invention, as shown in FIG. 10 (b), the end F of the transverse member 9b is pulled upward, so that the force F is concentrated and distributed in a certain direction (force F3). In addition to the horizontal member 9b, the horizontal member 9b can be efficiently peeled off. In addition, according to this example, in the longitudinal joint form peeling process, the end portions (T, T ′: see FIG. 9) on both sides of the horizontal member 9b can be punched out. Even if the transverse member 9b is torn off and remains on the transverse joint 4b in the middle of peeling from T, the remaining transverse member 9b remains by starting the peeling operation again from the other end T ′. Can be peeled cleanly. Further, when the peeling operation is started simultaneously from both ends T and T ′, the lateral member 9b can be peeled off very quickly, and more efficient construction is possible.

  And the protective film 8 is apply | coated to the surface layer material 7 and the joint part 4 (refer FIG. 2) from which the vertical member 9a and the horizontal member 9b were 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 paving method of the present example, by attaching the flip-up member 14, the end portion T of the horizontal member 9b can be flipped up only by peeling off the vertical member 9a. Thereby, since the edge part of the horizontal member 9b can be easily pierced from the joint part 4 without using a special tool, an operator's burden can be reduced significantly. Moreover, since the labor required for the horizontal joint form peeling process is reduced, the construction time as a whole can also be shortened, so that a more efficient and economical pavement method can be provided. In addition, since the end T of the transverse member 9b can be pierced without using a sharp tool such as a cone or an iron skewer, the surface layer material 7 may be damaged as compared with the case where the tool is forcibly rolled out. Can be reduced, and the pavement layer 1 having high design properties can be provided.

  Further, according to the pavement method of the present example, since the flip-up member 14 includes the adhesive layer 17, the flip-up member 14 is attached to the vertical member 9a without sewing or using a locking metal fitting. Can be simple. Further, since the flip-up member 14 is attached to the back surface side of the vertical member 9a, the surface layer 7 is smoothly applied without interference between the flip-up member 14 and the flange 21 when the surface layer material 7 is applied using the flange 21. Material 7 can be applied. Moreover, since the adhesive layer 17 on the front surface side of the flip-up member 14 has a stronger adhesive force than the adhesive layer on the back surface side, without increasing the burden on the peeling work of the lateral member 9b unnecessarily, The end portion T of the transverse member 9b can be surely punched, and an efficient pavement method can be provided.

  Furthermore, according to the pavement method of this example, since the flip-up member 14 is attached to the back side of the horizontal member 9b, a part of the horizontal member 9b is torn compared to the case where the flip-up member 14 is attached to the front surface or intermediate layer. There is little fear of tearing, and it can be peeled cleanly without remaining in the joint portion 4. Therefore, the pavement layer 1 with high designability can be provided using a simple method. Moreover, since the MMA resin mortar which uses MMA resin as a binder is applied as the surface layer material 7, the time required for curing can be shortened compared with the case where a hydrating cement mortar is used, and more quickly. Construction work can be realized. Further, since the joint mold member 9 includes the foamed layer 12, the portion that is in contact with the joint mold member 9, that is, the surface layer material 7 of the joint portion 4 is slowed to harden and is not easily fixed. It is. Therefore, the vertical member 9a and the horizontal member 9b can be smoothly peeled off without tearing in the middle of peeling or remaining on the joint portion 4, which is effective.

  Moreover, according to the pavement method of this example, since the flip-up member 14 has a cross shape having a width equal to or less than the width W of the vertical member 9a and the horizontal member 9b, the vertical member 9a and the horizontal member The flip-up member 14 can be attached without protruding from the end surface of 9b. Thereby, the joint mold member 9 can be peeled without impairing the shape of the beautiful tile pattern portion 3 of the surface layer material 7, and the pavement layer 1 with higher design 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 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, although the said embodiment illustrated what formed the smooth layer 5 and the joint layer 6 only once, 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.

  Moreover, in the said embodiment, although what performed the "vertical joint form attachment process" and the "horizontal joint form attachment process" after the "bounce-up member attachment process" was illustrated, it is limited to this order Instead, in short, any member may be used as long as the flip-up member 14 is attached to the vertical member 9a and the end T of the horizontal member 9b can be flipped up. Furthermore, the flip-up member 14 may be attached not only to the back surface side of the vertical member 9a and the horizontal member 9b but also to any part such as the surface or the intermediate layer.

  Moreover, in the said embodiment, although the substantially cross-shaped flip-up member 14 comprised by the 1st member 15 and the 2nd member 16 which exhibits the surface shape substantially the same as the 1st member 15 was illustrated, it is limited to this structure. Is not to be done. For example, a flip-up member having another shape as shown in FIG. 11 can be exemplified. In addition, the dashed-two dotted line part shown in FIG. 11 shows the arrangement position of the vertical member 9a and the horizontal member 9b. Specifically, as shown in FIG. 11A, a shape in which the adjacent horizontal member 9b is connected to the vertical member 9a disposed in a direction orthogonal to the rectangular flip-up member 22a. Alternatively, as shown in FIG. 11B, a cross-shaped flip-up member 14b to which a first member formed longer in the longitudinal direction than the second member is applied may be used. Moreover, as shown in FIG.11 (c), the 1st member and the 2nd member may be the flip-up member 22c formed in the substantially T shape, and other polygonal shapes, such as a circle, a triangle, a quadrangle, etc. It may be. However, when the shape is such that it does not protrude at least from the end surfaces of the vertical member 9a and the horizontal member 9b, the surface layer material 7 formed as the tile pattern portion 3 when the vertical member 9a and the horizontal member 9b are peeled off from the joint layer 6. Since the pavement layer 1 having a high design property can be provided without fear of causing a chipping, it is more preferable.
