Description

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

When forming a pond for raising small fish such as goldfish and medaka in the garden, stonework or concrete is placed in a hollow formed by digging the garden to the desired shape and depth. Alternatively, it is common to embed a pre-molded water tank such as FRP (Fiber Reinforced Plastics) or vinyl chloride. Such a pond has a shape, area, and depth according 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 from 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 biotope (life; bio; bio and place; topos; living place of organisms in the composite word of topos), it is an effective measure to provide a water field in the green area. Yes. Also, the water field should not necessarily be formed on the rooftop or the green area of the veranda.

However, when forming 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 that forms the base of the green space. There is a problem that the pond that is formed becomes too heavy.

  Also, when installing a water tank pre-formed with FRP or vinyl chloride, the range that can be installed is limited, so it is difficult to find a tank that can match the required installation range, There is a problem that the thing of the depth cannot be obtained. Furthermore, when this water tank is used for building greening, there is no size that can be placed on the rooftop or veranda, and the water level cannot be controlled with a commercially available product, and the weight becomes too large. In addition, there is a problem that the load is large and 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 which forms a water field on the roof of a building.

In addition, when a water field is formed on the roof, a deep water field cannot be formed due to the limitation of the allowable load capacity on the floor. For this reason, it has been difficult to secure a place of refuge and a good night's sleep from foreign enemies such as birds and cats living in water.

  In addition, since the amount of water in the water field cannot be easily increased, the water quality is likely to deteriorate, and the change in the water temperature due to the influence of outside air becomes violent, which tends to be a severe growth environment for the organisms in the water field.

  Furthermore, since the water depth in the water field becomes shallow, the amount of water due to evaporation is drastically reduced, and water must be replenished frequently in summer.

The purpose of the present invention is to form a water field having a desired shape at a desired site using a photocurable resin sheet, to ensure an evacuation site for living organisms living in the water field, a resting place, Water that can alleviate changes in water temperature due to deterioration of water quality and the influence of outside air, form a favorable growth environment for organisms in the water field, suppress a decrease in the amount of water due to evaporation, and reduce the frequency of water supply even in summer It is to provide a method for forming a field.

In order to solve the above problems, the first configuration of the water field forming method according to the present invention is a step of forming a water field body by recessing a flexible uncured photocurable resin sheet, The method comprises a step of forming a culvert portion on the side surface of the water field main body, and a step of applying light to the uncured photocurable resin sheet to cure it.

The second configuration of the method of forming the water field according to the present invention, in the step of forming the underdrain portion on the side surface of the water field body of the first configuration, the photocurable resin sheet wherein the water in the uncured state The undercover portion is formed by applying light to the uncured photocurable resin sheet in a state in which a bag-like portion is formed on the side surface of the field main body to form the culvert portion .

Moreover, the 3rd structure of the formation method of the water field which concerns on this invention makes a part of side surface of the said water field main body protrude in the process of forming a culvert part in the side surface of the water field main body of the said 1st structure. A projection is formed, and the uncured photocurable resin sheet is cured by applying light in a state of covering the top of the projection to form a lid member, and the projection is formed by the lid member. The culvert part is formed by covering.

The fourth aspect of the method of forming a water-field according to the present invention, in the step of forming the underdrain portion on the side surface of the water field body of the first configuration, and drilling a hole in the side surface of the water field body, the The culvert part is formed by attaching an open end of a cylindrical member having one end opened to the hole and the other end closed.

In the first water field forming method (hereinafter, the water field forming method is simply referred to as “construction method”), the photocurable resin sheet is deformed into a desired shape, and light is applied to the deformed photocurable resin sheet. By irradiating and curing, a water field can be easily formed on the rooftop or the floor of the veranda. 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 addition, by providing a culvert section in the water area, it is possible to secure an evacuation place, a resting place, and a safe egg-laying place for organisms that inhabit the water area.

  In addition, the amount of water in the water field can be increased by the amount of water in the underdrain, and sudden changes in water quality can be mitigated. In addition, fluctuations in water temperature due to the effects of summer and winter temperatures can be reduced. Thereby, a water field can be made into the comfortable growth environment for the creature of a water field.

  Furthermore, the water in the culvert is not easily affected by the outside air due to the heat insulating effect of the soil and plants above it. For this reason, the fluctuation | variation of the water temperature by the influence of the temperature of summer and winter can be made small.

  In addition, the amount of water in the entire water field is increased by the amount of water in the underdrain while keeping the area of the water surface (evaporation surface) of the water field. As a result, it is possible to alleviate a rapid decrease in the amount of water due to evaporation and to create a water field that does not require frequent water replenishment even in summer.

In the second method for forming a water field, a light-curing resin sheet in an uncured state having flexibility is supported on the light-curing resin sheet in a state of being supported in a bag shape by a culvert portion forming structure, for example. Can be applied and cured, and the culvert part and the water field body can be easily formed integrally.

Moreover, in the 3rd water field formation method , a culvert part is easily formed by providing the cover member which applied and hardened the photocurable resin sheet so that the upper part of the protrusion part of a water field main body may be covered. I can do it. Since the lid member and the water field main body can be manufactured separately, even a photo-curing resin sheet having a high curing speed can secure a time for applying a complicated design before curing, so that workability is good.

Moreover, in the 4th formation method of a water field, the cylindrical member which obstruct | occluded the other end can be made into a culvert part, and a deeper culvert part can be manufactured easily.

Moreover, the person who constructs the magnitude | size, volume, and shape of the water field formed by said each construction method can select freely. For this reason, the completed water field has an original shape, and a so-called original design can be realized.

[First embodiment]
1st embodiment of the formation method of the water field which concerns on this invention is described using figures. 1-3 is explanatory drawing of the formation method of the water field concerning this embodiment. This embodiment demonstrates as a construction method at the time of forming a water field in the green space provided on the roof or veranda of the building.

  As shown in FIG. 3, the water field A is installed in a green space B that realizes greening of the building. As shown in FIGS. 1 and 2, the green space B has a finishing sheet 2 laid on the top of a waterproof sheet 1 provided on the top surface of a concrete slab such as a rooftop of a building or a veranda (rooftop). The curb member 3 is arranged at the upper part of 2 along the periphery of the green space B set in consideration of the conditions such as the target roof area, the planar shape, or the allowable load capacity of the building, and surrounded by the curb member 3 A material obtained by mixing granular material, flake-like material, kneaded material alone or 2 or 3 materials (in this embodiment, granular artificial lightweight soil containing crushed particles of lightweight aerated concrete) ) To form 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. Further, in order to form the underdrain 9, a horizontal hole-type depression can be dug using an instrument such as a hand or a scoop.

  1 and 2 show that a bag-like portion 11 is formed by using a culvert forming structure 10 on a portion that becomes a side surface of a water field main body 8 of an uncured photocurable resin sheet 5 having flexibility. It is a figure which shows the procedure which irradiates and hardens | cures the light-curing resin sheet 5 of the uncured state in the state which put the culvert formation structure 10 in the shape part 11. FIG.

  FIG. 1A shows a state in which depressions are formed in the base layer 4 in accordance with the shapes of the water main body 8 and the underdrain 9. Subsequently, a flexible uncured photocurable resin sheet 5 is prepared to be laid on the upper surface of the base layer 4. When an ultraviolet curable resin sheet is used as the photocurable resin sheet 5, as shown in FIG. 1B, a carrier sheet 7 such as polyethylene for preventing adhesion is detachably pasted on both surfaces of the photocurable resin sheet 5. Further, the ultraviolet shielding sheet 6 is detachably attached to the surface of the carrier sheet 7 on one side, and is carried in a state of being accommodated in the ultraviolet shielding bag.

  As 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, reinforcing fiber amount: 600 g per square meter of chopped land mat, Thickness: 1.5mm, weight: 1.8kg per square meter.

  The uncured photocurable resin sheet 5 taken out from the ultraviolet shielding bag is laid on the upper surface of the base layer 4 with the ultraviolet shielding sheet 6 side facing as shown in FIG. The water body 8 is formed by recessing the sheet 5. That is, the step of forming the water field main body 8 by performing the depression of the photocurable resin sheet 5 with the surface covered with the ultraviolet shielding sheet 6 is performed. At this time, with the ultraviolet shielding sheet 6 facing upward so that light does not strike the photocurable resin sheet 5, the upper ultraviolet shielding sheet 6 is pressed, and these sheets 5, 6, 7 and the base layer 4 are pressed. Deform.

  And the process of forming the underdrain part 9 in the side surface of the water body main body 8 is performed. Therefore, as shown in FIG. 1 (c), a portion that becomes the side surface of the water field main body 8 of the uncured photocurable resin sheet 5 is recessed using a culvert forming structure 10 to form a bag-shaped portion 11. To do. At this time, the culvert portion 9 is formed by inserting the culvert formation structure 10 into the culvert portion 9.

  At this time, the deformation shape and depth of each of the sheets 5, 6, 7 and the base layer 4 are completely free, and the preference of the person to be deformed is 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, the carrier sheet 7, and the base layer 4, and thus the resident However, by setting the shape of the water field A by itself, it is possible to improve the participation consciousness for making the water field A.

  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 a folded portion, and then shown in FIG. As described above, the photocurable resin sheet 5 is removed from the photocurable resin sheet 5 at a portion other than the undergrowth forming structure 10 and the photocurable resin sheet 5 is exposed to ultraviolet rays in the atmosphere. The resin sheet 5 can be cured.

After the photocurable resin sheet 5 is cured at a site other than the underdrain forming structure 10, the undercover forming structure 10 is removed and the photocurable resin is cured at the undercover forming structure 10 as shown in FIG. The ultraviolet shielding sheet 6 placed on the resin sheet 5 is removed, and the photocurable resin sheet 5 is cured. As a result, a water field A made of the cured photocurable resin sheet 5 is formed on the upper surface of the base layer 4.

  That is, with the culvert forming structure 10 placed in the bag-shaped portion 11 forming the culvert portion 9, the portions other than the bag-shaped portion 11 of the ultraviolet ray shielding sheet 6 on the surface are peeled off and light is applied to the uncured photocurable resin sheet 5. Is applied and cured, the culvert formation structure 10 is once taken out from the bag-shaped portion 11, the ultraviolet shielding sheet 6 of the bag-shaped portion 11 is peeled off, and the culvert formation structure is again formed for forming the culvert portion 9. 10 is returned to the bag-shaped portion 11 and light is applied to the photocurable resin sheet 5 of the uncured bag-shaped portion 11 to be cured.

As a method of deforming the uncured photocurable resin sheet 5 to form the water field A, the uncured photocurable resin sheet 5 is laid on the base layer 4 forming the water field A and pressed from above. Then, the shape of the water field A may be formed. Moreover, as shown to Fig.1 (a), a hollow may be formed in the base layer 4 previously and the uncured photocurable resin sheet 5 may be deform | transformed according to the hollow.

After the photocurable resin sheet 5 is cured, a plurality of holes (not shown) are formed at predetermined height positions in the photocurable resin sheet 5 to complete the water field A. The hole defines the maximum water level in the water field A. When the water level rises due to rainwater or water supply, excess water can be drained from the hole. In this way, by providing a hole 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 water overflow. It becomes possible. Further, when the water field A is formed on the roof or veranda of the building, it is possible to maintain the structural safety of the building by keeping the water level of the water field A below the allowable water level determined from the allowable load of the building.

  After the ultraviolet shielding sheet 6 is peeled off as described above and light is applied to the uncured photocurable resin sheet 5 to cure it, when the bag-like part 11 is cured, the underlay structure 10 is removed from the bag-like part 11. Take out. And as shown in FIG.2 (b), the hardened photocurable resin sheet 5 is once removed from the base layer 4, and the carrier sheet 7 stuck on both surfaces of this photocurable resin sheet 5 is peeled off, and again. The cured photocurable resin sheet 5 is returned to the base layer 4.

  After that, as shown in FIG. 2 (c), a double-sided tape 12 is stuck on the surface of the photocurable resin sheet 5, and as shown in FIG. A finishing sheet 13 made of vinyl chloride is adhered with a double-sided tape 12.

  As an example of the finishing sheets 2 and 13, a vinyl chloride sheet such as Nipolan water-impervious sheet CVT (product name) manufactured by Nippon Poly Products Co., Ltd. having a thickness of about 1.0 mm can be used.

The forming method of the present embodiment uses a photocurable resin sheet 5 that is flexible in an uncured state and exhibits sufficient strength and hardness and water tightness as a tank for storing water after curing. Thus, the formation of the water field A having a desired shape and volume at a desired site is realized. By implementing this formation method , the water field A that satisfies the structural conditions such as the allowable load capacity of the building can be installed on the roof or veranda of the building.

  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 addition, people can get on and perform tasks such as cleaning.

  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.

  The shape of the culvert portion 9 is not particularly limited, and is preferably set as appropriate according to the size and shape of the water field A and the water field installation location.

  The photocurable resin sheet 5 includes an ultraviolet curable resin sheet and an infrared curable resin sheet, both of which can be preferably used. These photo-curing resin sheets 5 are flexible so that a person can freely mold them in an uncured state, and exhibit sufficient hardness and strength when cured.

  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 5 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 the target water field A, a predetermined operation is performed with the ultraviolet ray shielding sheet 6 superimposed on the ultraviolet curable resin sheet. It is preferable to carry out. And after shaping | molding in a desired shape, it is possible to accelerate | stimulate hardening by removing the ultraviolet-ray shielding sheet 6. FIG.

  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.

  In addition, although this embodiment demonstrated an example at the time of sticking the finishing sheet 13 on the surface of the photocurable resin sheet 5, by changing the finish of the surface of the photocurable resin sheet 5 to coating etc., for example, It is also possible to produce a pond or river with a bottom like a rock collapsed, or a pond or river with a bottom of a soil, or a pond or river with a pebble bottom.

The lid member 15 is formed, and the culvert portion 9 is formed.

[Third embodiment]
Next, a third embodiment of the water field forming method according to the present invention will be described with reference to the drawings. 15 to 18 are explanatory diagrams of the water field forming method according to the present embodiment. The same parts as those in the above embodiments are denoted by the same reference numerals and the description thereof is omitted.

  In the present embodiment, as shown in FIG. 18 (c), a hole is formed in the side surface of the water body main body 8, and one end of the hole is opened, and the open end portion of the tubular member with the other end closed is formed. The culvert part 9 is formed by attaching. First, as shown in FIGS. 15A and 15B, an uncured photocurable resin sheet 5 taken out from the ultraviolet shielding bag is laid on the upper surface of the base layer 4 with the ultraviolet shielding sheet 6 side facing up. Then, the photocurable resin sheet 5 is recessed to form the water field main body 8.

  Thereafter, as shown in FIG. 15 (c), the ultraviolet ray shielding sheet 6 is peeled off and cured by applying light to the uncured photocurable resin sheet 5, and then cured as shown in FIG. 15 (d). The cured photocurable resin sheet 5 is removed from the base layer 4 and the carrier sheets 7 attached to both sides of the photocurable resin sheet 5 are peeled off, and as shown in FIG. The resin sheet 5 is returned to the base layer 4.

  Thereafter, as shown in FIG. 16 (b), a double-faced tape 12 is applied to the surface of the photocurable resin sheet 5, and as shown in FIG. 16 (c), soft chloride that protects against breakage due to the ingress of plant roots. A finishing sheet 13 made of vinyl is attached with a double-sided tape 12.

  Next, as shown in FIG. 16 (d), holes 5g are formed in the cured photo-curable resin sheet 5 with a forcible. The holes 5g may be drilled after the finish sheet 13 is adhered with the double-sided tape 12 with the cured photocurable resin sheet 5 removed from the base layer 4.

  On the other hand, as shown in FIG. 17 (a), a double-sided tape 12 is attached to the outer periphery of the open end of the pipe 19 that is a cylindrical member that is open at one end and closed at the other end, as shown in FIG. 17 (b). As described above, the connection sheet 20 is adhered to the outer periphery of the open end of the pipe 19 by the double-sided tape 12.

  The double-sided tape 12 used when connecting the pipe 19 made of vinyl chloride is a non-woven fabric base material sandwiched with an acrylic pressure-sensitive adhesive and can be about 1 mm to 2 mm thick.

  Next, as shown in FIG. 17 (c), a double-sided tape 12 is attached to the surface of the finishing sheet 13 around the hole 5g. Then, the connecting sheet 20 provided in the pipe 19 is inserted from the back side of the hole 5g formed in the photocurable resin sheet 5 to penetrate the hole 5g, and as shown in FIG. A cut is made along the axial direction of the pipe 19. Then, as shown in FIGS. 18 (a) and 18 (b), a finished sheet spread from the notch of the connection sheet 20 provided on the pipe 19 and adhered to the surface side of the photocurable resin sheet 5 by the double-sided tape 12. Stick it to 13.

  Further, as shown in FIG. 18 (b), a doughnut-shaped patch 21 having a size corresponding to the hole 5g and provided with an adhesive layer on the back side is attached to the connection sheet 20 and the finishing sheet 13 for waterproofing. The patch 21 may be attached to the finishing sheet 13, the connection sheet 20, and the double-sided tape 12 via the double-sided tape 12. Then, the photocurable resin sheet 5 provided with the pipe 19 is returned to the base layer 4, and the culvert portion 9 is formed by the pipe 19 connected to the water field body 8.

  The hole 5g is drilled in a portion of the photocurable resin sheet 5 that becomes the side surface of the water field main body 8. The hole diameter of the hole 5 g is smaller than the diameter of the pipe 19. Thereby, when the pipe 19 is fitted into the hole 5g, a gap is not formed between the photocurable resin sheet 5 and the pipe 19, and water leakage from the gap can be prevented.

  The pipe 19 is formed of a vinyl chloride pipe or the like with one end closed and the water body main body 8 side opened. The pipe 19 is disposed so as to lie on the base layer 4 in a substantially horizontal direction. The pipe 19 can be freely set in length and thickness, and can have various shapes such as a cylinder and a cylindrical shape having a polygonal cross section.

  The culvert part 9 is a horizontal hole formed by water entering the pipe 19. For this reason, living things such as small fish and aquatic insects inhabiting the water place A enter the culvert section 9 to become an evacuation place and a resting place where they can protect themselves from external enemies such as birds and cats. In addition, by growing aquatic plants in the underdrain 9, it is possible to provide a safe spawning place for organisms such as small fish and aquatic insects.

  In addition, although the said embodiment demonstrated the example in the case of installing the photocurable resin sheet 5 which provided the pipe 19 in the base layer 4, returning to the base layer 4, it hardened | cured the photocurable resin sheet 5 hardened | cured. After the hole 5g is formed, a retrofitting method in which the pipe 19 is inserted into the hole 5g from the water body body 8 side and inserted into the base layer 4 may be used. Accordingly, the material constituting the base layer 4 moves and deforms, and a horizontal hole having the shape of the pipe 19 is formed as the underdrain 9.

  As described above, by providing the culvert part 9 in the water area A, the culvert part 9 becomes a blind spot of birds, cats, etc., out of reach, and the evacuation area, resting place, and safety of living creatures in the water area A A safe spawning place.

  In addition, the amount of water in the water field A can be increased by the amount of water in the underdrain 9, and a sudden change in water quality can be mitigated. In addition, fluctuations in water temperature due to the effects of summer and winter temperatures can be reduced. Thereby, the water field A can be made into a comfortable growth environment for organisms in the water field A.

  Furthermore, the water in the underdrain 9 is not directly affected by the outside air due to the heat insulating effect of the soil and plants above it. For this reason, the fluctuation | variation of the water temperature by the influence of the temperature of summer and winter can be made small.

  In addition, the amount of water in the entire water field A increases by the amount of water in the underdrain 9 without changing the area of the water surface (evaporation surface) of the water field A. Thereby, it is possible to alleviate a rapid decrease in the amount of water due to evaporation, and to make a water field A that does not require frequent water replenishment even in summer.
