Description

  The present invention relates to a laying method for laying a water field having a desired shape at a desired site by using an uncured photocurable resin sheet having flexibility.

  When laying a pond for breeding small fish represented by goldfish in the garden, stonework or concrete is placed in a hollow formed by digging the garden to a desired shape and to a desired depth, Alternatively, it is common to embed a pre-molded water tank such as FRP or PVC. Such a pond has an area and depth corresponding to the size and number of fish and aquatic insects to be grown.

  On the other hand, recently, so-called greening of buildings is being promoted to green the verandas, roofs, or walls in order to cope with the heat island phenomenon in the city. Even the roofs in urban areas are not all high-rise buildings, and the roof area of detached houses occupies an overwhelmingly large area. Therefore, realizing the greening of these detached houses will contribute to the mitigation of the heat island phenomenon.

  Building greening is realized by providing a soil layer on the rooftop or on the veranda floor, and then planting grass, flowers, and shrubs in this soil layer. In order to maintain the wet state of the soil layer provided on the rooftop or on the veranda, it is necessary to configure so as to be able to retain water supplied by rainwater or water. In order to achieve such an object, there is a technique (see, for example, Patent Document 1) in which a water retention layer is provided below the soil layer.

  Moreover, the technique which waterproofs a building using a photocurable prepreg sheet | seat is proposed (for example, refer patent document 2). In this technique, after fixing a plurality of strips to a waterproof base, a photocurable prepreg sheet is covered, temporarily bonded, and cured by irradiation with light to be waterproofed.

  When the rooftop and veranda are greened, it is expected that birds and insects will fly to the flowers and shrubs planted in the soil layer. In the case of greening for the purpose of such a biotope, it is desirable that there is a small water field in the green area. In addition, the water field should not necessarily be laid on the rooftop or on the veranda, but it has a high value even in the garden of the house.

  However, when laying a water field on the rooftop, it is necessary to satisfy the conditions such as the allowable load capacity on the rooftop and the floor of the veranda and the space used as the base of the green space. There is a problem that the weight of the pond to be laid becomes too large.

  In addition, when installing a water tank pre-molded with FRP or PVC, the place where it can be installed is limited, so it is difficult to find a tank that can match the required installation place, the desired shape and depth There is a problem that you can not get the right thing. Furthermore, when trying to adopt this aquarium for building greening, there is no size that can be placed on the rooftop or veranda, the problem is that the commercial product is too heavy, the bulkiness is large, There is also a problem that it cannot be carried into a desired installation place, and a plurality of artificial members are required for construction.

  Although the technique of Patent Document 1 has a function of retaining water below the soil layer, the water retaining layer is not open to the atmosphere and does not have the idea of a water field for small birds and insects.

  Although the technique of patent document 2 performs waterproofing construction of a building, there is no idea of laying a water field on the roof of a building.

  An object of the present invention is to provide a construction method for laying a water field having a desired shape at a desired site very easily using a photocurable resin sheet.

In order to solve the above problems, the first water field laying method according to the present invention is configured such that when a granular substance, a piece-like substance, or a kneaded substance is constituted and mixed and pressed. A water field is laid on a base layer that can be deformed according to the method, wherein a flexible uncured photocurable resin sheet is laid on a predetermined position of the base layer, and the uncured light is laid. Pressing the upper surface of the curable resin sheet to form depressions in the uncured photocurable resin sheet and the base layer, and then applying light to the uncured photocurable resin sheet to cure. It is what.

  Further, the second water field laying method according to the present invention is a method of laying a water field on a base layer composed of a granular material, a piece-like material, and a kneaded material, either alone or in combination. A depression is formed at a predetermined position of the base layer, and an uncured photocurable resin sheet having flexibility is laid on the surface of the depression, and then light is applied to the uncured photocurable resin sheet. It is characterized by being applied and cured.

Furthermore, a third water field laying method according to the present invention is a method for laying a water field on a base surface, and has a shape that matches the shape of the target water field at a predetermined position on the base surface. part established a Kariwaku members have a deformation the photocurable resin sheet laying a photocurable resin sheet uncured flexible in the forming portion into a shape along the surface of the molding section And then curing by applying light to the uncured photocurable resin sheet, and after the photocurable resin sheet is cured, the temporary frame member is removed and laid on the base surface. It is what.

  In the first water field laying method (hereinafter, the water field laying method is simply referred to as “construction method”), granular materials including soil and sand, flakes including wood chips, and kneaded materials including clay are used. A water field can be easily laid on the base layer in which the substances are individually or in a state where two to three substances are mixed. That is, when the base layer is pressed from the outside, it can be easily deformed according to the pressing force, and the uncured photocurable resin sheet has sufficient flexibility. For this reason, the photocurable resin sheet and the base layer are placed in a desired position in the base layer, and the photocurable resin sheet and the base layer are pressed by pressing from the top of the base photocurable resin sheet. It can be transformed into a shape.

  Therefore, a water field integral with the base layer can be laid by irradiating light to the photocurable resin sheet deformed into a desired shape and curing it. The cured photocurable resin sheet has sufficient strength and water tightness to retain water, and can sufficiently function as a water field for flying birds and insects.

  In particular, since the cured photocurable resin sheet is in a state of being laid on the surface of the base layer, a substance constituting the base layer is present on the lower surface of the photocurable resin sheet. The weight of the water field made of the conductive resin sheet can be supported by the base layer. For this reason, a distributed load acts on the base layer, and a large burden is not partially caused.

  Further, in the second construction method according to the present invention, a recess having a desired shape is formed in the base layer in advance, and a photocurable resin sheet is laid in the recess and cured, so that the base has a desired shape. A water field supported by the strata can be laid.

  Moreover, in the 3rd construction method which concerns on this invention, the shape of a temporary frame member is created in a desired shape previously, and this temporary frame member is installed in a base surface, and the water field according to this shape is laid. I can do it. In particular, by removing the temporary frame member after the photocurable resin sheet is cured, the water field composed of the cured photocurable resin sheet can be made into a single configuration and moved to a desired installation location. The water can be used as it is at the construction site.

  In each of the above methods, the position of the basement layer and the position of the temporary frame members are not limited, and when greening a building, it is possible to target the rooftop or veranda floor, or a part of the garden. There is no problem at all. Therefore, it is possible to easily lay the water field without limiting the installation site.

  The water fields in the above methods are not limited in size or volume. For example, when laid in a part of the garden, the area and volume are not limited at all, and small fish can grow. You can also lay a pond. In addition, when greening a building and laying it on a rooftop or a veranda, it is possible to lay a water field having an area and volume corresponding to the allowable load capacity of the floor. That is, in the construction method according to the present invention, it is possible to lay a water field having an area and a volume corresponding to the load condition of the site to be laid.

  The water field laid by each of the above-mentioned construction methods will determine what part the construction person will press with what level, what kind of dent will be formed in the base layer, and how the shape of the temporary frame member will be , Can be selected freely. For this reason, the completed water field has an original shape, and a so-called original design can be realized.

  In particular, since the work is performed when the photocurable resin sheet is in an uncured state, it does not require skilled skills, so for example, a resident of the house lays a water field on the rooftop or garden of the house himself Can be enjoyed with a sense of participation in housing construction.

  Moreover, the material carried into the water field laying site is a sheet-shaped or roll-shaped photo-curable resin sheet, and can be laid without causing any special problem regardless of the location of the water field. . In particular, since the material is in the form of a sheet or a roll, the volume is small and the weight is small. Therefore, the man-hours required for the work can be minimized, and depending on the size of the water field, one person can lay it well Work can be done.

  In addition, since the cured photocurable resin sheet has sufficient strength and rigidity, even if the ground is soft when laying in a garden or park, it can stand on its own without requiring reinforcement of the ground. Yes, there is no choice of where to put the water.

  Hereinafter, the preferable form at the time of implementing the construction method of the water field which concerns on this invention is demonstrated.

  The laying method of the present invention utilizes a photo-curable resin sheet that is flexible in an uncured state, and exhibits sufficient strength and altitude as a tank for storing water after curing and water tightness. A water field having a desired shape and volume is laid at a desired site. By implementing this laying method, it becomes possible to install a water field that satisfies the structural conditions such as the allowable load capacity of the building on the roof or veranda of the building, and the garden can be expanded according to the size of the garden. It becomes possible to install a water place with depth.

  The water field in the present invention is not limited to a particular size or function, but means a water bird or insect that can fly and bathe or drink. Therefore, it may be anything that can exhibit the above functions, and may have a sufficiently wide area and depth. In particular, although it is a water place, it is preferable that it has such a width and depth that it can grow aquatic insects such as turtles, gengoro or flax, larvae of insects such as larvae, and even small fish of about medaka. is there. Thus, the water field is not intended to assume the size of area, volume, planar shape, depth, and the like.

  The water basin according to the present invention can be laid on the rooftop or the floor of a veranda when realizing greening of a building, and the installation place such as a garden of a detached house or a green space of a park should be limited. It is possible to lay without. In particular, when laying a water field, an uncured photocurable resin sheet can be formed in a desired shape and volume, so when greening a building, the conditions including the allowable load in the target building must be met. It can be easily satisfied. Moreover, when installing in a garden, a park, etc., since the conditions of the allowable load load at the time of installing in a building are lose | eliminated, it becomes possible to improve freedom degree, such as an area, a depth, or a volume.

  In the first laying method, when the base layer is pressed from the outside, it is configured as a layer that can be deformed in response to the press, and the granular material, the flake material, and the kneaded material are each singly or mixed. Formed in a state.

  The granular material constituting the base layer does not limit the size of the material or grains, but soil, sand or small gravel, concrete crushed grains, slag crushed grains, and synthetic resin bead-shaped substances, etc. It is possible to use a substance selected from these granular substances alone or a mixture of a plurality of substances. Similarly, a piece of material does not limit the thickness and length of the piece and the piece, such as a piece formed of a flake like a wood chip or a piece of synthetic resin formed into a flake. It is possible to use a single substance or a mixture thereof. Similarly, the viscosity of the kneaded substance is not limited, and a paste-like substance such as clay can be used.

  When configuring the base layer, it is not limited at all whether to use a granular material, a piece of material, a paste-like material alone, or a mixture of a plurality of materials, and the flowers to be planted in this base layer And should be optimized according to the type and nature of the shrub.

  Since a depression is formed in advance in the base layer in the second laying method, it does not matter whether the base layer is deformed in response to external pressure. That is, by using the base layer as a granular material, a piece-like material, or a kneaded substance alone, or by mixing a plurality of materials, the base layer is pressed, scraped, and dug to obtain a desired It is possible to form a recess having the shape and depth.

In the first laying method and the second laying method, as roof including veranda or roof of a building, the bottom structure of the base layer as concrete slabs or concrete panel or lightweight concrete panel (ALC panels) When a water field is installed in a part formed by simple panels, metal plates, wooden structures, tiles, etc., the basement layer should not disturb the rooftop or veranda of the building.

  For this reason, a building protective layer that can prevent the structure from being damaged is provided below the base layer and between the building structure (for example, an ALC panel). Is preferred. As the building protective layer, it is preferable to use a synthetic resin dish-shaped member, a protective sheet formed by combining a waterproof sheet having high waterproofness and a root-proof sheet through which plant roots cannot pass, and the like. .

  In addition, when the basement layer itself is composed of ground, such as in a garden, it is possible to lay the waterfield directly on the basement layer without any special treatment on the lower side of the water base to be installed. .

  The base surface in the third laying method is not particularly limited, and may be the surface of the part where the water field is to be installed. As such a base surface, when applying a water field to building greening, set the roof of the building or the floor of the veranda, and when setting the water field in a garden or park, set the ground of the garden or park It is preferable.

  The temporary frame member used in the third laying method does not limit the material or the structure, but it is necessary to remove after the photocurable resin sheet is cured and a water field is formed on the base surface. . For this reason, it is necessary that the whole is configured as two or more separable members. Such a temporary frame member can be configured by a combination of a member that defines the periphery of the water field and a rising member that defines the depth.

  The container which comprises a water field is comprised with the hardened photocurable resin sheet. The photocurable resin sheet includes an ultraviolet curable resin sheet and an infrared curable resin sheet, both of which can be preferably used. In the uncured state, these photocurable resin sheets have flexibility that allows a person to freely mold them, and exhibit sufficient hardness and strength when cured.

  As the ultraviolet curable resin sheet or the infrared curable resin sheet constituting the photocurable resin sheet used in the present invention, a commercially available product can be used. Several thicknesses are standardized in such a photocurable resin sheet, and it is preferable to select a sheet having an optimum thickness corresponding to the size of the water field to be laid.

  The ultraviolet curable resin sheet is cured in response to ultraviolet rays, and the infrared curable resin sheet is cured in response to infrared rays. Therefore, it is preferable to select and use from these photocurable resin sheets according to climatic conditions such as the weather and temperature of the construction day. For example, when an ultraviolet curable resin sheet is used, it can be cured by ultraviolet rays contained in natural light.

  For this reason, when an ultraviolet curable resin sheet having flexibility in an uncured state is formed in a target water field, a predetermined operation is performed in a state where the ultraviolet ray shielding sheet is stacked on the ultraviolet curable resin sheet. It is preferable. And after shaping | molding in a desired shape, it is possible to accelerate | stimulate hardening by removing an ultraviolet-ray blocking sheet.

  When an infrared curable resin sheet is used, it is preferable to forcibly irradiate infrared rays with an infrared irradiation lamp in order to cure after molding. In this way, uniform irradiation can be realized without unevenness by irradiating with infrared rays.

  Next, an embodiment of the first laying method according to the present invention will be described with reference to FIG. The water field A shown in FIG. 1 (c) is installed in the green space B that realizes the greening of the building. Therefore, in this embodiment, the water field A is constructed as a construction method when laying the water field on the green space provided on the roof of the building or on the veranda. Has been.

  As shown in FIG. 5A, the green space B is formed on the rooftop of the building or on the top of the protective sheet 2 laid on the top surface of the concrete slab 1 such as a veranda (rooftop). Alternatively, the curb member 3 is arranged along the periphery of the green space B set in consideration of conditions such as the allowable load capacity of the building, and a granular material, a flake material, The base layer 4 is formed by filling a kneaded substance alone or a substance obtained by mixing two or three substances (in this embodiment, a granular artificial lightweight soil containing crushed grains of lightweight cellular concrete). Yes. Further, a water retention layer 7 in which a material such as a nonwoven fabric having water retention property is laid is formed below the base layer 4.

  When the base layer 4 is pressed from the upper surface side using an instrument such as a hand or a scoop, the material constituting the base layer 4 is moved and deformed in response to the press, and a depression having any shape is formed. It is possible to form.

  An uncured photocurable resin sheet 5 having flexibility is laid on the upper surface of the base layer 4, and preparation for laying the water field A is completed. When the photocurable resin sheet 5 is an ultraviolet curable resin sheet, the ultraviolet shielding sheet 6 is placed on the surface of the laid photocurable resin sheet 5. It is preferable that the ultraviolet shielding sheet 6 has an area larger than the area of the photocurable resin sheet 5 so that the photocurable resin sheet 5 can be reliably covered. However, if the ultraviolet shielding sheet 6 is too large compared to the photocurable resin sheet 5, the deformation state of the photocurable resin sheet 5 becomes difficult to understand when forming a water field, so that the size is moderate. is required.

  In this embodiment, an ultraviolet curable resin sheet is used as the photocurable resin sheet 5. As such an ultraviolet curable resin sheet, there is an AFR sheet M6 (sales company, Asahi Kasei Geotech Co., Ltd.). The specifications of this sheet are: resin main component: epoxy acrylate, reinforced fiber amount: chopped land mat per square meter 600 grams, thickness: 1.5 mm, weight: 1.8 kilograms per square meter.

  Next, as shown in FIG. 2B, a person presses the ultraviolet shielding sheet 6 covering the photocurable resin sheet 5 from above to deform the sheets 5 and 6 and the base layer 4. At this time, the deformation shape and depth of each of the sheets 5 and 6 and the base layer 4 are completely free, and the preference and skill of the person to be deformed are reflected. Therefore, it is possible for a person (for example, a child) who lives in the target building to perform the deformation of the photocurable resin sheet 5, the ultraviolet shielding sheet 6, and the base layer 4, and thus the resident himself can By setting the shape of the water field A, it is possible to improve the participation awareness for the greening of the building.

  After the photocurable resin sheet 5 is deformed into a desired shape and the periphery of the photocurable resin sheet 5 constituting the periphery of the water field A is folded downward to form the folded portion 5a, FIG. As shown, the ultraviolet curable sheet 6 is removed, and the photocurable resin sheet 5 is exposed to ultraviolet rays in the atmosphere to cure the photocurable resin sheet 5. The water field A made of the cured photocurable resin sheet 5 is laid on the upper surface of the base layer 4.

  After the photocurable resin sheet 5 is cured, a plurality of holes 5b are formed at predetermined height positions in the photocurable resin sheet 5 to complete the water field A. The hole 5b defines the water level in the water field A. When the water level rises due to rain water or water spray, the water can be supplied from the hole 5b to the water retention layer 7 through the base layer 4. is there. Thus, by providing the hole 5b that regulates the water level, it is possible to prevent water from overflowing from the water field A and to prevent the outflow of organisms such as small fish and aquatic insects that inhabit the water field A due to the overflow of water It becomes possible to do.

  The water field A configured as described above has sufficient rigidity to accommodate water and has high water tightness. For this reason, the water stored in the water field A does not leak, and can function as a drinking place for birds or a bird path. The stored water also enables the growth of small fish, such as medaka, aquatic insects, such as gengoro and flax, as well as larvae and aquatic plants such as tadpoles and gooses.

  In this embodiment, since the upper surface of the base layer 4 is covered with the photocurable resin sheet 5 and then deformed, it is suitable for forming a water field A having a relatively large area and a shallow depth.

  Next, an embodiment of the second laying method according to the present invention will be described with reference to FIG. In the drawing, the same reference numerals are given to the same parts and the parts having the same functions as those of the above-described embodiment, and the description thereof is omitted (the same applies hereinafter).

  As shown in FIG. 1A, first, the base layer 4 constituting the green space B is prepared. Next, as shown in FIG. 4B, a recess 10 is formed in the base layer 4 at the top. In forming the depression 10 in the base layer 4, it is not limited in what procedure and in what manner the depression 10 is formed, and the base layer 4 may be formed by pressing by a person, or a scoop or the like. Alternatively, the base layer 4 may be formed by removing the material constituting the base layer 4.

  Next, as shown in FIG. 2C, the photocurable resin sheet 5 covered with the ultraviolet shielding sheet 6 is laid in the depression 10 formed in the base layer 4, and the sheets 5 and 6 are placed on the surface of the depression 10. Deform along. After these sheets 5 and 6 are deformed along the depression 10 formed in the base layer 4, the ultraviolet shielding sheet 6 covering the photocurable resin sheet 5 is removed as shown in FIG. Thus, the photocurable resin sheet 5 is exposed to ultraviolet rays and cured, and the water field A is formed by the cured photocurable resin sheet 5.

  As described above, even when the depression 10 is formed in the base layer 4 in advance and the photocurable resin sheet 5 is laid in the depression 10 to form the water field A, the formed water field A is The shape of the recess 10 will be reflected. Therefore, it is possible to define the shape of the water field A depending on the shape of the depression 10 formed.

  In this embodiment, since the recess 10 is formed in the base layer 4 in advance, both the area and the depth can be formed in any way. Therefore, the shape which can be applied is various, and it is effective also when laying a water field in a garden or a park.

  Next, another embodiment relating to the first laying method and the second laying method will be described with reference to FIG.

  In the figure, the water field A is installed by adopting the above-described first laying method or second laying method, and is formed by bending the periphery of the photocurable resin sheet 5 downward. A portion 5c and a support portion 5d formed by bending horizontally from the leg portion 5c are formed. The support portion 5 d reaches the upper portion of the water retention layer 7 provided in the lower layer of the base layer 4 and is supported by the water retention layer 7.

  Therefore, the water field A can be independent regardless of the strength and vulnerability of the base layer 4. That is, when the water field A is installed on the roof of a building, the soil that constitutes the base layer 4 is hard and the place that may damage the protective sheet 2, or the soil that constitutes the base layer 4, particularly It is advantageous to adopt in a place where the surface soil is soft and it is difficult to support the water field A as shown in FIGS.

  In the above Examples 1 to 3, when the photocurable resin sheet 5 is directly laid on the base layer 4 to form a dent, or when the dent 10 previously formed on the base layer 4 is covered, a plurality of photocurable properties are obtained. The resin sheets 5 can be connected to each other and cured. For this reason, a small mountain is built in a large garden or park to produce a satoyama, and the photocuring resin sheet 5 is continuously laid from the satoyama in a desired route to produce a flowing stream. Is also possible.

  Furthermore, by changing the finish of the surface of the photo-curable resin sheet 5, a pond or river with a soil bottom is created, or a pond or river with a rocky bottom is created. It is also possible to do.

  Next, an embodiment of the third laying method according to the present invention will be described with reference to FIG. In this embodiment, when laying the water field A, the photocurable resin sheet 5 is supported and supported by the temporary frame member C installed on the concrete slab 1 on the roof or veranda of the building which becomes the base surface. The water frame A composed of the cured photocurable resin sheet 5 is laid on the slab 1 by curing and then removing the temporary frame member C.

  The temporary frame member C is composed of at least two temporary frames 15 that are divided in the vertical direction, and the temporary frame 15 is a plate-shaped molding part for supporting and molding the photocurable resin sheet 5 over the entire surface. 15a, and the molding portion 15a can be supported by a columnar support portion 15b.

  The molding portion 15a has a planar shape and depth that match the planar shape and depth of the target water field A. The forming portion 15a may be formed with a region for forming the water field A and a rising portion separately, and both (the region and the rising portion) are formed continuously. There may be. When the rising part is formed independently, when the photocurable resin sheet 5 is arranged in the region, there is a possibility that the curvature of the photocurable resin sheet 5 becomes large and is difficult to deform.

Therefore, the molding unit 15a in this embodiment is formed in a continuous curved surface shape, and constitute the molding portion 15a by a member using a plywood. Moreover, the support part 15b has the some rib 15c which supports the lower surface side of the shaping | molding part 15a, and is comprised so that the load which acts on the shaping | molding part 15a can be supported by this rib 15c. Further, a groove 15 d corresponding to the thickness of the photocurable resin sheet 5 is formed in the rib 15 c in order to form the folded portion 5 a at the periphery of the photocurable resin sheet 5.

As shown to Fig.4 (a), the some temporary frame 15 is made to oppose and mutually approach, and the shaping | molding part 15a becomes the shape of the water field A, The photocurable resin sheet 5 is shape | molded in this state It is possible. Further, as shown in FIG. 3C, the cured photocurable resin sheet 5 can be removed by separating the temporary frames 15 apart from each other.

  First, as shown in FIG. 5A, the divided temporary frames 15 are brought close to each other and combined so that the molded portion 15a has the shape of the water field A. Next, as shown in FIG. 4B, the photocurable resin sheet 5 covered with the ultraviolet shielding sheet 6 is laid on the molding portion 15a of the temporary frame member 15, and these sheets 5 and 6 are placed on the molding portion 15a. The shape is deformed along the surface, and the periphery is inserted into the groove 15d.

  After the photocurable resin sheet 5 is deformed along the molded portion 15a and the groove 15d and the ultraviolet shielding sheet 6 is deformed along the molded portion 15a, the ultraviolet shielding sheet 6 is removed as shown in FIG. The photocurable resin sheet 5 is cured by exposure to ultraviolet rays. After the photocurable resin sheet 5 is sufficiently cured, each temporary frame member 15 is moved in the direction of the arrow, and the cured photocurable resin sheet 5 is detached from the temporary frame member 15 as shown in FIG. Mold. Thereafter, a plurality of holes 5 b are formed at predetermined positions of the cured photocurable resin sheet 5.

  As described above, the present embodiment does not require a soil layer. For this reason, it becomes possible to form the water field according to this shape, regardless of the shape of the molding portion 15a of the temporary frame member 15. Therefore, in this embodiment, it is possible to lay not only the water place A installed in the green space formed on the roof but also the water place installed in the garden of a detached house, planting a park, or the like. .

  Next, another embodiment of the above-described third laying method will be described with reference to FIG. In FIG. 2A, reference numerals 16 to 18 denote temporary frames, and reference numerals 16a to 18a denote molding portions formed on the temporary frames 16 to 18, respectively. The temporary frames 16 and 17 function as a temporary frame member C of one water field A when opposed to each other and one or more temporary frames 18 are arranged between the temporary frames 16 and 17. When it functions as a temporary frame member C of the large water field A.

  The temporary frames 16 to 18 are molded from a foamed synthetic resin, and such a foam is preferable because it is lightweight and easy to process. The temporary frames 16 to 18 can be processed by the resident by setting the shape of the temporary frames 16 to 18, and the participation consciousness for the house can be exhibited. However, it is also possible to provide a standardized or semi-standardized temporary frame member for residents who are not concerned with the shape or who are not confident in the finish.

  FIG. 4B is a water field A configured using temporary frames 16 to 18, and a leg portion 5 c is formed along the periphery, and a support portion 5 d is horizontally formed from the lower end portion of the leg portion 5 c. Is formed. This configuration is the same as the shape of the third embodiment described above. In the third embodiment, the water field A is supported and laid by the base layer 4, whereas in this embodiment, it is supported by the temporary frames 16-18. And differ in the formation.

  The laying procedure of the water field A in the present embodiment will be described. The temporary frames 16 to 18 are continuously formed to form depressions made of the molded portions 16a to 18a, and the photocurable resin sheet 5 is laid along the molded portions 16a to 18a and along the outer peripheral surfaces of the temporary frames 16 to 18a. Further, the end portion is molded in the horizontal direction and then cured. After the photocurable resin sheet 5 is cured, the photocurable resin sheet 5 is lifted and removed from the mold, and the water field A can be formed by forming the hole 5b at a predetermined position.

  The water field A formed as described above does not require the base layer 4 (soil layer) serving as a support base. For this reason, it becomes possible to lay in any place without limiting the installation place of the water place A.

  In each of the above-described embodiments, an ultraviolet curable resin sheet is used as the photocurable resin sheet, and the photocurable resin sheet is deformed and then exposed to ultraviolet rays in the atmosphere to be cured. However, the present invention is not limited to this example, and after naturally curing the photocurable resin sheet, it is possible to positively promote curing by irradiating ultraviolet rays using an ultraviolet irradiation lamp. It is.

  Further, in each of the above-described examples, the case where an ultraviolet curable resin sheet is used as a photocurable resin sheet has been described, but the construction procedure is not changed even when an infrared curable resin sheet is used, In order to cure the infrared curable resin sheet, the difference is whether infrared rays are forcibly irradiated.
