Description

  The present invention is intended to protect the landscape and the natural environment, and is built on the surface of retaining walls, revetments, dams, etc. constructed in the civil engineering field, multiple pseudo stones placed in parks and hydrophilic rivers, and walls and soil in the architectural field. The present invention relates to a method for producing a plurality of pseudo stones to be embedded in a surface such as a flower bed and a curb stone in a general household.

  Conventionally, in the civil engineering field, many artificial concrete products have been used for road retaining walls, residential land-building retaining walls, river revetments, riverbed maintenance, dams, and the like. However, since these concrete products have a simple artificial shape such as a rectangular shape, it is a problem to impair the natural scenery. Therefore, even if it is an artificial building object, as a form that is more natural and less uncomfortable, a block imitating a masonry / stone-clad pattern on the surface, a block embedded with natural stone, and the like have come to be used. In the architectural field, natural stones and artificial stones are embedded in buildings, exterior walls, and soils in consideration of the landscape, and natural stones are placed as curbs on flower beds in ordinary households. There are many.

  Natural stones used in such places are generally purchased from gravel collectors or imported from overseas, which requires a large amount of money for purchase or has the desired shape, size, and color. It may be difficult to secure the required amount of natural stone. Therefore, in recent years, many pseudo stones and their production methods have been proposed in place of these natural stones (for example, JP-A-6-339915 and JP-A-2002-361633).

  In the conventional method for producing pseudo stones, an elastic female frame is formed by applying silicon rubber or the like to natural stone that becomes a model of pseudo stone, and FRP resin or the like is applied to the outer surface of the elastic female die. After forming the holding mold frame by curing and removing these elastic female mold frame and holding mold frame from natural stone, sand, steel, etc. are further added so as not to easily deform these elastic female mold frame and holding mold frame. It is carried out by a process such as fixing with, and driving in pseudo stone material.

Here, since the elastic female mold is consumed by repeated use about 30 to 50 times, this process must be repeated every time it is consumed. If you do not have a natural stone that can be used as a model for the artificial stone, the elastic female formwork and the holding formwork cast from the natural stone will not be used as a formwork for manufacturing the artificial stone. A process of manufacturing a male mold that replicates the texture of natural stone by applying and curing is also performed. In this case, using this male mold as a prototype, a mold for producing pseudo stone is manufactured by the same process of forming an elastic female mold and a holding mold from natural stone. In addition to silicon rubber, urethane rubber, FRP resin, or the like may be used as a material used for the mold for manufacturing the pseudo stone. A pseudo stone is manufactured by a process such as driving a pseudo stone material into the mold for manufacturing pseudo stone.

  However, (1) In the prior art, there are many processes for producing the mold for producing pseudo-stone, and it takes much time to cure silicon rubber, FRP and the like. (2) The manufacturing cost of the mold for producing pseudo stones becomes large. (3) Although the number of times of repeated use differs depending on the material, the mold for producing pseudo-stones is consumed due to the production of pseudo-stones, and the exhausted objects cannot be recycled and become waste objects. (4) When manufacturing pseudo stones, it is necessary to apply a release agent that improves the separation from concrete to the molds for manufacturing pseudo stones. After use, the molds must be cleaned every time. ing.

  The present invention is an improvement of the above-mentioned conventional problems, and in consideration of landscape and natural environment conservation, a plurality of pseudo stones, parks and hydrophilic rivers embedded in the surfaces of retaining walls, revetments and dams constructed in the civil engineering field. It is possible to simplify the manufacturing method of pseudo stones that are placed on the surface such as walls and dirt in the building field, and to place multiple pseudo stones as curbs such as flower beds in general households, and provide pseudo stones at low cost An object of the present invention is to provide a method for producing an artificial stone.

  In order to solve the above problems, the present invention is configured as follows.

  1st invention considers scenery and natural environment conservation, retaining wall built in the civil engineering field, revetment, artificial stone embedded in the surface of dam, etc., pseudo stone arranged in parks and hydrophilic rivers, wall in construction field Or stones embedded in the surface of soil, soil, etc., and a method of producing a plurality of artificial stones arranged as curbs such as flower beds in ordinary households, such as natural stones such as cobblestones, round stones, calculus stones, and stones The male mold replicated on the basis of was pushed into a clay lump containing oil that had good releasability from other objects, and the mold was taken, and after removing the natural stone or male mold, the natural stone or male mold was pushed in Therefore, the concave part formed in the clay block containing the oil content has a good releasability from the object that contains moisture such as mortar that constitutes pseudo stone and dissipates the moisture after hardening, and it is used as a female mold for manufacturing pseudo stone as it is. , Pour a cement-type fluidity temporal solidification material such as ordinary mortar, and further embed a predetermined jig according to the use of the pseudo stone produced in the fluidity temporal solidification material. It is removed from the clay block containing the oil by lifting the tool upward, and further, the shape is changed using the excellent plasticity of the clay block containing the oil, and this is repeatedly used as the female mold. It is characterized by that.

  According to a second invention, in the first invention, a female die is completed by adding a concave surface processing by a spatula or / and a push die to a concave portion of a clay lump containing oil obtained by pushing a natural stone or a male die. This female mold is characterized by pouring a cement-based fluidity time-solidifying material.

3rd invention considers scenery and natural environment conservation, retaining wall built in the civil engineering field, revetment, artificial stone embedded on the surface of dam, etc., pseudo stone arranged in parks and hydrophilic rivers, wall in construction field A method for producing pseudo stones that are arranged in plural as a curbstone such as a flower bed in a general household,
A clay lump containing oil that forms an indentation that simulates the shape of a pseudo stone such as natural stone by applying concave surface processing to the clay lump containing oil that has good releasability from other objects with a spatula or / and a pressing die. The above-mentioned concave portion has a good releasability from an object that contains moisture such as mortar constituting pseudo-stone and dissipates moisture after hardening, as it is as a female mold for manufacturing pseudo-stone, and there is cement system such as mortar for pseudo-stone, normal mortar, etc. By pouring the fluidity time-solidifying material, and further embedding a predetermined jig according to the use of the pseudo stone produced in the fluidity-time solidification material, and pulling the jig upward after the fluidity-time solidification material is cured. It is characterized in that it is produced by removing from the oil-containing clay lump, further changing the shape by utilizing the excellent plasticity of the oil-containing clay lump, and repeatedly using it as the female mold.

  The present invention has the following effects.

  (1) Clay containing oil has excellent plasticity, easily deforms by pressing the object, and has the property of faithfully copying the shape of the pressed part of the pressed object. The natural stone or male texture can be faithfully transferred by pressing a natural stone such as cobblestone or a male mold, which is a model of a pseudo stone, into a clay lump containing oil, and performing molding.

  (2) By using the above-mentioned method, it is possible to easily form a concave portion that faithfully reproduces natural stone or male texture, and further, this concave portion can be used as it is as a female mold for manufacturing pseudo stones. In addition, it is possible to procure a female mold for producing pseudo stones in a short time. In this way, a pseudo-stone can be produced by directly placing a cement-based fluidity solidifying material directly into a female mold that can be easily made of clay containing oil, and it can be easily used for spatulas and pressing molds. Since the shape and texture can be changed, any number of various kinds of artificial stones can be easily manufactured with a limited number of natural stones or artificial male dies.

  (3) Since the oil-containing clay contains oil, it has a good property of peeling off from other objects as a whole, and the natural stone or male mold is pushed into the clay block containing oil to mold When taking a mold, it can be easily and neatly removed without applying a release agent or the like to natural stones or male molds, and does not require any special cleaning after the mold is taken.

  (4) Manufacture of pseudo stone can be easily manufactured by pouring a cement-based fluid temporal solidification material into the mold for producing pseudo stone and removing the fluid temporal solidification material from clay containing oil after hardening.

  (5) As described above, since the oil-containing clay has a good releasability, it has good releasability from an object that contains moisture such as mortar that constitutes pseudo stone and that dissipates moisture after curing. In the production of pseudo stone, a predetermined jig according to the use of the pseudo stone is embedded in the unsolidified fluid aging solidified material, and it is pulled up upwards by using the jig. It can be easily removed from the oily clay without disturbing the texture of the transferred natural stone, etc., without the need for special release agent application or cleaning after demolding.

  (6) Because the female mold formed of clay blocks containing oil has moderate hardness, flexibility and good peelability, it will not break easily even if repeated production of pseudo stones. It can also be used at any time, and it is also possible to perform partial repairs and shape changes using the excellent plasticity of oil-containing clay, re-kneading the whole, from the same or another natural stone or male mold etc. It is possible to mold again and use.

  (7) Since it can be used repeatedly as a female mold and can be recycled as a material, the generation of waste objects can be suppressed at low cost.

  (8) Since the female mold formed of a clay lump containing oil according to the present invention can be provided easily and at low cost, female molds of various shapes and textures can be easily procured. Can do.

  (9) Also, the pseudo-stone mortar can be easily changed in color, etc. depending on the type and composition of the aggregate to be blended and the use of pigments. Therefore, combining this technique with multiple female molds with different shapes and textures. This makes it possible to produce pseudo stones with a wide variety of shapes, textures, and colors.

  (10) Using these various types of pseudo stones, placing stone stones such as cobblestones, spar stones, and machinoku stones in a simulated manner, and using the joints of the pseudo stones as the boundary, the rear side in the thickness direction is used as the base part, The base portion has at least one uneven fitting portion that joins the members, and depending on the masonry form to be simulated, in addition to the above, in the upper and lower connecting portions, the rear side in the upper thickness direction of the lower precast member By exchanging and arranging the upper precast member shifted to the rear side, it becomes possible to construct a structure such as a retaining wall where the joint pattern of the joint portion between the precast members is not uniform, It is possible to faithfully reproduce (represent) masonry masonry and machima masonry.

  (11) Arbitrary planar shape in which the concave and convex fitting parts are formed in all directions in accordance with the shape and size of the pseudo stone arranged on the surface, the number of arrangements, the direction of arrangement, and the combination of members. Using a formwork such as a panel type or block type, a variety of pseudo stones, such as the shape, texture, and color of the pseudo stones to be placed, are placed on the surface to produce precast members, and multiple precast members are combined. By this, it is possible to construct various structures such as retaining walls that faithfully reproduce (represent) the traditional methods and aspects of various types of masonry such as cobblestones, field stone masonry, and machinari stone masonry.

  (12) There are two types of stones: (i) “no stones” (including cobblestones) that can be collected without collecting them from rivers, mountains, etc. (b) “round stones” obtained by breaking large stones. , (C) There are “Garishi” used without breaking the shape, and (D) “Machiishi” made by dividing it into the specified dimensions. There are (Iiteikoi) loading, (F) dredging, (G) Yaba misconduct. In the present invention, it is possible to manufacture any of the above-mentioned stones (i) to (d), and the stone structure imitation structure object using the stones (i) to (g) described above in various ways. It is what.

  After removing the pseudo stone 7, the product is usually washed with water to make the product, but if necessary, (1) washing with an acid-based washing agent, (2) Bishan finish, (3) coloring with paint, etc. There is also.

  2A to 2F show the mold making process according to the second embodiment. 2 (a) -1, FIG. 2 (b) -1, FIG. 2 (c) -1, FIG. 2 (d), FIG. 2 (e), and FIG. 2 (f) are the mold drawings according to the third embodiment. The process of is shown.

  First, in Steps 1 and 2 of Embodiment 2 shown in FIGS. 2 (a) and 2 (b), oil components in which natural stones such as cobblestones (or artificial male molds manufactured in separate steps) 3 are packed in a frame body are used. It is pressed against the clay lump 2 that contains it to make a mold. The pushing of the natural stone (or male mold) 3 into the clay block 2 containing the oil is the same as in the first embodiment. In step 3 of the second embodiment shown in FIG. 2 (c), a predetermined shape is partially added to the concave portion 4 made by mold making using a spatula 10 or the like, and an arbitrary shape and texture are changed.

  Steps 4, 5, and 6 of the second embodiment shown in FIGS. 2 (d), (e), and (f) are steps 3, 4, and 5 of the first embodiment shown in (c), (d), and (e) of FIG. The same. That is, the flowable solidifying material 5 is charged, the jig 6 is embedded, and the pseudo stone 7 is hardened / demolded in this order.

  Next, in steps 1 and 2 of the third embodiment shown in FIGS. 2 (a) -1 and (b) -2, the clay lump 2 containing the oil packed in the frame 1 is roughly shaped with a spatula 10 or the like. The concave part 4 to be a female mold is shaped and formed by performing a predetermined manual processing. Further, in the step 3 of the second embodiment shown in FIG. The pressing mold 11 is pressed, and the shape and texture are arbitrarily formed in the concave portion 4 which becomes a female mold through the combined process of the spatula 10 and the pressing mold 11, thereby making the clay female mold 8 containing oil. be able to.

  Steps 4 to 6 of Embodiment 3 are the same as Steps 4, 5, and 6 of Embodiment 2 shown in FIGS. 2D, 2E, and 2F, and these figures are incorporated. That is, the flowable solidifying material 5 is charged, the jig 6 is embedded, and the pseudo stone 7 is cured and demolded in this order.

  In the first, second, and third embodiments described above, the process of manufacturing the pseudo stone by one individual is shown, but it is also possible to connect and manufacture a plurality of pseudo stones at the same time depending on the method of stacking such as the masonry to be simulated. is there.

  Next, the manufacturing process of the precast member for a retaining wall structure simulating cobblestone using the pseudo stone 7 manufactured by any of the methods of Embodiments 1 to 3 will be described with reference to FIG.

  3A to 3D show the manufacturing steps 1 to 4 of the retaining wall structure precast member 16 simulating cobblestone.

  In step 1 shown in FIG. 3A, reinforcing reinforcing bars 14 are arranged via a support member 13 on a mold 12 having a predetermined shape according to the size of the cobblestone to be simulated and how to stack them. In step 2 shown in FIG. 3 (b), concrete 15 serving as a base portion of a precast member for retaining wall structure simulating cobblestone is driven.

  In step 3 shown in FIG. 3 (c), while the concrete 15 is not consolidated, the pseudo stone 7 (that is, the pseudo stone cobble 7a) manufactured by the pseudo stone manufacturing method described above is disposed (the pseudo stone cobble 7a in FIG. 3d). Is produced by the method of Embodiments 1 to 3 with a cobblestone of approximately the same size as this). As a result, a part of the pseudo stone 7 and the jig 6 protruding from the back side are embedded in the concrete 15, and the concrete 15 is cured, so that the pseudo stone 7 is firmly attached to the concrete 15 via the part of the pseudo stone 7 and the jig 6. And fixed. In addition, when arranging a plurality of pseudo stones 7 on the concrete 15, it is arranged from the lower side of the precast member 16 shown in FIG. 4, and joint portions 17 are formed between the pseudo stones 7. Expresses the state of cobblestones.

  Next, in step 4 shown in FIG. 3 (d), after the concrete 15 is hardened, the retaining wall building precast member 16 simulating the cobblestone removal is completed.

  FIG. 4 shows a perspective view and a cross-sectional view of the precast member 16 for retaining wall construction that simulates cobblestone manufacturing, which is manufactured in the process of FIG. 3, and a number of pseudo stones 7 on the front surface of the concrete base portion 15a. (Pseudo-stone cobblestone 7a) is fixed, and expresses a state where cobblestone is actually loaded.

Retaining wall construction precast member 16 simulating cobblestones is composed of a plurality of different types, textures, colors, etc. of pseudo stones 7 arranged on the surface, and each of pseudo stones 7 (pseudo stone cobble stones 7a). It is a precast member that can faithfully reproduce a conventional stone wall made of cobblestone because of the shape of the precast member that is deeply carved and has been devised so that the seam is not conspicuous. FIG. 4 is an example of a precast member that reproduces reciprocating stacking, which is the traditional method of cobblestone stacking.

  FIG. 5 (a) is a front view showing a masonry simulation precast member 16 that simulates cobblestones, and FIG. 5 (b) is an assembled front view in which a plurality of precast members 16 are assembled. These are examples of a longitudinal side view.

  5 (b) and 5 (c), the back surface of the concrete base portion 15a of the retaining wall construction precast member 16 simulating cobblestone is fixed to the inclined frame 20 of the support frame 19 so as to be independent. The pseudo stone retaining wall 21 simulating cobblestone construction is constructed by installing it so that it does not move to the surface and filling the back with concrete 23. In this case, the precast member 16 for a masonry simulated structure is made uniform as a whole assembled (that is, a pseudo stone retaining wall 21 simulating cobblestone masonry) by changing (changing) the surface masonry modeling for each precast member. It is not a natural thing, and it can faithfully reproduce the traditional natural masonry.

  Here, since the upper part of the precast member 16 is cut away from the rear side in the thickness direction, the uppermost pseudo stone 7 of the precast member 16 slightly extends from the upper end 22 of the concrete base portion 15a as shown in FIG. 5 (c). It will be protruding.

  Therefore, the lower end portion of the concrete base portion 15a of the upper-stage precast member 16 is slightly shifted to the rear side from the arrangement surface of the lower-stage precast member 16, and the concrete base portion 15a of the lower-stage precast member 16 is arranged. As shown in the front view of FIG. 5 (b), the upper and lower side precast members 16 are placed on and supported by the upper end 22 and further shifted to the side. It is possible to construct a retaining wall that simulates a cobblestone pattern that has been built up.

  FIGS. 6A and 6B are front views showing another example of the precast member 46 for a masonry simulated structure simulating cobblestone, and FIG. 6C is an assembly in which a plurality of precast members 46 are assembled. The front view and FIG. 6D are examples of the longitudinal side view.

  6 (a) and 6 (b), the surface layer of the precast member 46 has a plurality of pseudo stones 7 (pseudo stone boulders 7a) that are all different in shape, texture, color, etc. or are composed of a plurality of types. The base part 51 is the rear side in the thickness direction with the joints of the plurality of pseudo stones 7 as the boundary, and the base part 51 has a concave and convex fitting part for joining the precast members in at least one direction or all directions in plan view. It is the shape which has. The base portion 51 has a shape corresponding to the type of member such as a panel type or a block method.

  This planar shape can be a shape according to the shape and size of the pseudo stone to be placed, the number of placement, the orientation of the placement, and the way of combining the members, and the size is as shown in FIGS. 6 (a) and 6 (b). By changing it, when it is combined, the seam part will not pass, and it will be possible to faithfully reproduce the traditional natural masonry. The precast member 46 in FIGS. 6 (a) and 6 (b) is an example of a precast member that reproduces the saddle stacking, which is a traditional method of cobblestone stacking.

  This precast member 46 is formed in the same process as the precast member manufacturing process shown in FIG. 3 in accordance with the shape, size, orientation and number of placement of the pseudo stones, and the way of combining the members. Manufactured by making an arbitrary shape having uneven fitting portions in all directions in a plane. In addition, not only concrete but also mortar, porous concrete, glass fiber, carbon fiber reinforced mortar, concrete, or the like is used as the base portion of the precast member to be cast into the mold. good.

  6 (c) and 6 (d) show an example in which the precast member 46 is pasted as a member for repairing the existing retaining wall 52, and the basic crushed stone 53, the basic concrete 54, and the base block according to the portion to be repaired. 55, and in order, the adhesive wall material 56 such as polymer mortar is applied and adhered to both the surface of the existing retaining wall 52 and the back surface of the precast member 46. The landscape retaining wall 58 is constructed by installing and connecting the connection anchor 57 at the position. Here, a plurality of pseudo stones 7 (pseudo stone cobblestones 7a) that are all different in shape, texture, color, or the like or are composed of a plurality of types are arranged on the surface layer portion of the precast member 46 constituting the landscape retaining wall 58. Since the shape of the precast member 46 is devised so that the joint portion is not conspicuous, the entire assembly (that is, the scenic retaining wall simulating cobblestones) is not uniform and has been conventionally used. A natural masonry can be faithfully reproduced. In addition, the construction method of the landscape retaining wall 58 is not limited to the example shown here, and may be performed by various methods using existing technology.

  Further, the retaining wall can be constructed by fixing the precast member 46 by the same method as shown in FIGS. 5B and 5C and filling the back surface with concrete.

  FIG. 7A is a front view showing still another example of the precast member 66 for a masonry simulated structure simulating cobblestone, and FIG. 7B is an assembled front view in which a plurality of precast members 66 are assembled. FIG.7 (c) is an example of the vertical side view.

  In this example, two pseudo stones 7 (pseudo stone boulders 7a) having different shapes, textures, colors, etc. are arranged on the surface layer portion of a single precast member 66, and irregularities according to the shape and orientation of the pseudo stones to be arranged. The fitting portion has a shape that is planarly provided in at least one direction or all directions. In the example shown in FIG. 7A, the substantially hexagonal shape is different depending on the shape and arrangement direction of the pseudo stone 7 in order to reproduce the reciprocating stacking which is a traditional method of cobblestone stacking. As two types of planar shapes joined together in the direction, the rear side in the thickness direction is a block-type base portion.

  Since it is sufficient for the precast member 66 having such a shape to be configured so that a maximum of two pseudo stones 7 can be arranged, the overall weight can be reduced, and one person can use one heavy machine without using any heavy machinery. An operator can carry with both hands.

  This precast member 66 is formed in the same process as the precast member manufacturing process shown in FIG. 3 in accordance with the shape, size, orientation and number of arrangement of the pseudo stones, and the way of combining the members. Manufactured by forming a block-type base portion having uneven fitting portions in all directions in a plane. At this time, not only concrete but also any fluidity such as mortar, porous concrete, glass fiber, carbon fiber reinforced mortar and concrete, which is not limited to concrete, is driven into the mold as the base part of the precast member. An aging solidifying agent may be used, and the reinforcing bars need not be arranged.

  Further, here, the pseudo stone 7 is shown as manufactured by the pseudo stone manufacturing method described above, but a predetermined jig is embedded in advance on the back of the pseudo stone or natural cobblestone manufactured by other manufacturing methods. The member may be manufactured using a device such as a pressure vibration compaction device or a centrifugal pressure vibration compaction device.

FIGS. 7B and 7C are examples of cobblestone simulated retaining walls 68 in which the precast member 66 is constructed in accordance with the conventional method of constructing the common block retaining wall, and is disposed on each precast member 6. The pseudo-stone 7 is different in shape, texture, color, etc., or is composed of a plurality of types. Further, this cobblestone simulated retaining wall 68 is constructed on the base block 55, and the precast member 66 is disposed on the front surface of the back chestnut as shown in FIG. 7C. Since the shape of the precast member 66 is devised so that the seam portion is not conspicuous, the assembled whole (that is, the retaining wall simulating cobblestones) does not become uniform, and the conventional natural You will be able to faithfully reproduce the masonry.

  In addition, in the example mentioned above, although it explained about the case of the cognitive block type precast member 66 expressing the round trip of cobblestone arrangement where two pseudo stones 7 are arranged, it is not limited to such a case, It may be a precast member combined with a conventional block stacking technique such as a Satoshi block type in which only one pseudo stone 7 is arranged or a large block type in which three or more are arranged. In addition, in order to enable one worker to carry with both hands without using any heavy machinery, it is desirable to configure 1 to 3 pseudo stones.

  Furthermore, the shape may be changed depending on the type and shape of the stones, the way of stacking (such as piles), and the way they are combined, and not only the block type but also the panel type, the concrete retaining wall driving formwork It may be used as

  8 (a) and 8 (b), the surface layer of the precast member 71 has a plurality of pseudo stones 72 simulating a common knowledge composed of different shapes, textures, colors, etc. The base in the thickness direction with the joints of the plurality of pseudo stones 72 as a boundary is a base part, and the base part 51 has a concave and convex fitting part for joining the precast members in a plane at least in one direction or all directions. It is the shape which has.

  This planar shape can be changed depending on the shape and size of the pseudo stone to be arranged, the number of arrangement, the orientation of the arrangement, and the way of combining the members. By changing the size as shown in FIGS. 8A and 8B, When they are combined, the joints will not pass, and it will be possible to faithfully reproduce conventional natural masonry. The precast member 71 in FIGS. 8 (a) and 8 (b) is an example of a precast member that reproduces the Yawa masonry, which is a traditional method of machinite masonry.

  This precast member 71 is formed in the same process as the precast member manufacturing process shown in FIG. 3 in accordance with the shape, size, orientation and number of arrangement of the pseudo stones, and the way of combining the members. Manufactured by making an arbitrary shape having uneven fitting portions in all directions in a plane. In addition, not only concrete but also mortar, porous concrete, glass fiber, carbon fiber reinforced mortar, concrete, or the like is used as the base portion of the precast member to be cast into the mold. good.

  Moreover, although the pseudo stone 72 arrange | positioned at the surface layer part of the precast member 71 is preferably manufactured by the manufacturing process of the pseudo stone shown in FIG. 1 or FIG. 2, it may be manufactured by other existing manufacturing processes.

  FIGS. 8C and 8D show an example in which a hand-holding wall is constructed by using the precast member 71 as a casting form for the concrete retaining wall, and the concrete base portion 51 of the precast member 71 is inclined with respect to the support frame 83. It is fixed to the frame 84 so as to be self-supporting, and is installed so as not to move on the retaining wall foundation 86 provided on the foundation crushed stone 85. Further, the back form frame 87 is inclined by the back form frame support hardware 88. By connecting and supporting the frame 84 and filling the concrete 89 between them, a pseudo stone retaining wall 90 simulating Satoshi masonry is constructed. In this case, a plurality of pseudo stones 72 having different shapes, textures, colors, or the like or a plurality of types are arranged on the surface layer portion of the precast member 71 constituting the surface of the pseudo stone retaining wall 90. The shape of is designed so that the joints are not conspicuous, so the whole assembled (that is, the pseudo stone retaining wall simulating the Machinari stone masonry) will not be uniform, and conventional natural masonry Can be faithfully reproduced. In addition, the construction method of the pseudo stone retaining wall 86 is not limited to the example shown here, and may be performed by various methods using existing techniques.

  FIG. 9 is a perspective view and a cross-sectional view in which a pseudo stone cobblestone 24 is constructed with the pseudo stone 7 (pseudo stone cobble 7a). The shape, texture, color, etc. of the pseudo stone cobblestone 24 arranged in the flower bed 25 of a general household are all different or can be configured in multiple types. Can be built.
