[0001]
BACKGROUND OF THE INVENTION
  The present invention is a panel.the body'sIt relates to a manufacturing method.
[0002]
[Prior art and problems to be solved by the invention]
  For example, a pearlite water supply / drainage layer has been proposed as a water supply / drainage layer that drains excess water supplied to the bottom of the soil for planting plants during rooftop greening or supplies water to the soil during drying.
[0003]
  This pearlite water supply / drainage layer is formed by laying pearlite obtained by crushing pearlite, a kind of vitreous igneous rock, and baking and foaming at a high temperature of around 1000 ° C., because this pearlite is a porous substance. Water retention and drainage are demonstrated.
[0004]
  By the way, pearlite has low strength, and therefore has poor load resistance.
[0005]
  Therefore, when thickly cultivated soil is laid on the pearlite water supply / drainage layer, or when heavy trees are planted on the culture soil, the pearlite water supply / drainage layer is destroyed by the weight, and clogging occurs due to crushed pearlite, When water is excessively supplied to a greening site where a plant such as a tree is vegetated, the water is retained in the greening site for a long period of time, causing root rot.
[0006]
  On the other hand, special drainage panels (mats) have also been proposed for use in rooftop greening.
[0007]
  This special drainage panel is a synthetic resin mat with a plurality of ridges and ridges arranged alternately and in a grid pattern on the surface, and is arranged at the bottom of the greening part where plants are vegetated. It spreads gravel and uses the concave streak as a drainage route, exhibits good drainage, and can be used without worrying about root rot of plants.
[0008]
  However, this special drainage panel has too good drainage and drains the rain that has fallen on the greening site more than necessary, so that water supply to the upper soil of the special drainage panel is hardly performed and water is likely to be insufficient. There is a problem.
[0009]
  The present invention solves the above-mentioned problems, can exhibit excellent drainage and water retention over a long period of time, and can also exhibit superior strength as compared with the prior art. Extremely practical panelthe body'sA manufacturing method is provided.
[0010]

[Action and effect of the invention]
  Main departureManufactured by MingIn the flannel body 2, the mixing ratio of the cement 4 to the carbide 3 is 1 m of the amount of the carbide 3.^ThreeThe amount of cement 4 is set to 50 kg to 200 kg, and the mixing ratio of the carbide 3 and cement 4 is appropriate, so that the conventional pearlite water supply / drainage can be obtained while the panel body 2 is porous (porous). Demonstrates superior strength compared to the layer.
[0017]
  Therefore, for example, when used as a drainage layer when greening the rooftop, the panel body 2 can exhibit excellent load resistance because it has high strength, and thus the soil of the culture soil disposed on the panel body 2 Even if the thickness is set thick, the panel body 2 is not destroyed by the weight of the soil, and even if a heavy plant is vegetated on the soil, the panel body 2 is destroyed by the weight of the plant. Therefore, the panel body 2 is not clogged by crushed cement or the like, and can be used alone or in combination with other materials, for example, greening suitable for plant vegetation. The base can be formed well.
[0018]
  Moreover, since the panel body 2 is porous, it has a large number of voids 15 and 18 through which water can flow, whereby the panel body 2 can exhibit good drainage.
[0019]
  That is, even if the panel body 2 becomes excessive in water due to, for example, rain or water sprinkling, the excess water passes through the gaps 15 and 18 and is well drained out of the panel body 2.
[0020]
  In addition, since the carbide 3 is a porous material and has a large number of small voids 16, the small voids 16 have an effect of retaining moisture, and thus the panel body 2 exhibits good water retention. To do.
[0021]
  That is, for example, even when the panel body 2 is used for rooftop greening and it has not rained for a while, the moisture retained in the small gaps 16 of the carbide 3 is supplied to the culture soil and supplied to this culture soil. Plants can be well vegetated by moisture.
[0022]
  In addition, since the carbide 3 is a porous material and has excellent adsorptivity, it is possible to adsorb, for example, fertilizer in addition to water into the large number of holes, and thus the panel body 2 is excellent. Also exhibits fertilizer.
[0023]
  Further, since the neutralizing material is mixed in the panel body 2, for example, even if the panel body 2 is mixed with a large amount of carbide 3 to increase the alkalinity of the panel body 2, Since the panel body 2 is neutralized by the Japanese material, it is prevented that the panel body 2 becomes strongly alkaline and adversely affects the growth of plants, for example.
[0024]
  Moreover, since the panel body 2 is not a granular material like a conventional pearlite but a panel shape, it can form a layer that exerts a draining action or the like simply by placing it on a site where it is desired to be laid, and therefore the construction work is also easy It becomes.
[0025]
  In addition, this departureManufactured by MingAs described above, since the mixing ratio of the carbide 3 and the cement 4 is appropriate and excellent in durability, the flannel body 2 ensures the above-described drainage, water retention, and fertilizer retention over a long period of time. And it demonstrates well.
[0026]
  Further, since the carbide 3 can exhibit excellent adsorptivity as described above, for example, when the panel body 2 of the present invention is disposed in sewage, it adsorbs contaminants and contaminants in the sewage. In addition, the sewage can be purified.
[0027]
  Moreover, since the carbide | carbonized_material 3 can adsorb | suck not only the fertilizer mentioned above but an odor, the panel body 2 also exhibits the outstanding deodorizing property.

  In addition, the cement in a present Example is what mixed water with cement powder and solidified, and concrete is what contains gravel etc. as an aggregate in cement.
[0036]
  As the neutralizing material, superphosphate lime is adopted. In addition to lime superphosphate, when the inside of the panel body 2 becomes alkaline or acidic, a material that can neutralize it, such as ammonium sulfate, may be employed.
[0037]
  The polymer water-absorbing material 8 employs a synthetic resin-based water-absorbing material (for example, trade name: Glass Power G-300 manufactured by Kurita Kogyo Co., Ltd.).
[0038]
  As the thickener, water-soluble cellulose or the like (for example, trade name: SFCA2000 manufactured by Shin-Etsu Chemical Co., Ltd.) is employed. This thickener is added depending on the application.
[0039]
  Subsequently, each of the above materials charged in the stirrer is stirred and mixed in a dry state.

  That is, the panel body 2 has a permeability coefficient of 1.0 × 10.⁰cm / s to 1.0 × 10^-3Excellent drainage performance with cm / s.
[0061]
  The panel body 2 has a compressive strength of 10 t / m.²Excellent load resistance.
[0062]
  In the second embodiment, the manufacturing method of the panel body 2 containing the polymer water-absorbing material 8 as a whole using the mixture containing the polymer water-absorbing material 8 formed in the first embodiment has been described. In one embodiment, a mixture is formed without mixing the polymer water-absorbing material 8, and a panel body is formed using the mixture, thereby producing the panel body 2 not including the polymer water-absorbing material 8. Yes (see FIG. 2).
[0063]
    Third embodiment
  The third embodiment is a method for manufacturing the panel body 2 in which the polymer water-absorbing material 8 is disposed not in the whole panel body 2 but in an intermediate portion.
[0064]
  First, as in the second embodiment, an acrylic plate coated with an oil component is set on a mold frame arranged on a machine line, and a filter 6 is set thereon. The reason for setting the acrylic plate coated with the oil component and the filter 6 is the same as in the second embodiment.
[0065]
  Subsequently, a predetermined amount (for example, half of the total amount) of the mixture that does not include the polymer water-absorbing material 8 formed in the first embodiment is filled in the mold.
[0066]
  Subsequently, the mixture filled in the mold is spread and shaped using a trowel or the like to form a porous layer 19 constituting one surface side of the panel body 2.
[0067]
  Subsequently, the polymer water-absorbing material 8 is disposed on the molded mixture. In the third embodiment, the polymer water-absorbing material 8 is partially disposed on the molded mixture.
[0068]
  Subsequently, the polymer water-absorbing material 8 partially disposed on the mixture is thinly spread and the polymer absorbent material layer 10 is formed.
[0069]
  Subsequently, a predetermined amount (for example, half of the total amount) of the mixture containing no polymer water-absorbing material 8 formed in the first embodiment is placed on the polymer water-absorbing material 8 disposed on the mixture in the mold. Fill. As a result, the polymer water-absorbing material layer 10 is formed at an intermediate portion of the mixture not including the polymer water-absorbing material 8.
[0070]
  Subsequently, the mixture filled in the mold is spread and shaped using a trowel or the like to form a porous layer 19 constituting the other surface side of the panel body 2.
[0071]
  Subsequently, a pressure plate coated with an oil component is set on the molded mixture. The reason for setting the pressure plate is the same as in the second embodiment.
[0072]
  Subsequently, the mixture is pressurized at a predetermined pressure. The pressure at this time is set to the same pressure as in the second embodiment.
[0073]
  Subsequently, the acrylic plate is pushed upward by hydraulic pressure, so that the mixture retained in the mold is removed from the mold to obtain the panel body 2 (see FIG. 3).
[0074]
  According to the third embodiment, it is possible to manufacture the panel body 2 in which the polymer water-absorbing material 8 is partially disposed in the middle portion of the panel body 2 in the thickness direction.
[0075]
  Moreover, the panel body 2 which can exhibit the desired water absorption (water retention) can be manufactured by setting the amount of the polymer water-absorbing material 8 disposed in the middle part of the panel body 2 to a desired amount.
[0076]
  In the third embodiment, the polymer water-absorbing material 8 is partially disposed in the middle part of the panel body 2. However, the polymer water-absorbing material 8 is disposed in the whole middle part of the panel body 2. May be installed. Thereby, the panel body 2 in which the polymer water-absorbing material layer 10 is disposed in the entire intermediate portion of the panel body 2 can be manufactured.
[0077]
  Since the third embodiment is as described above, a panel body that can partially retain moisture at an intermediate portion of the panel body 2 by partially disposing the polymer water-absorbing material layer 10 between the porous layers 19. 2 can be easily manufactured.
[0078]
  That is, a good water retention effect can be exhibited at the site where the polymer water-absorbing material layer 10 is formed, and a good drainage effect can be exhibited at the 19 porous layer sites where the polymer water-absorbing material layer 10 is not disposed. An excellent panel body 2 can be easily manufactured.
[0079]
  Moreover, the water supply / drainage property of the panel body 2 can be adjusted by adjusting the amount of the polymer water-absorbing material 8 disposed between the porous layers 19.
[0080]
    Fourth embodiment
  The fourth embodiment is a method for manufacturing the panel body 2 in which the polymer water-absorbing material 8 is disposed only on one surface side of the panel body 2 to form the polymer water-absorbing material layer 10.
[0081]
  First, similarly to the second embodiment and the third embodiment, an acrylic plate coated with an oil component is set on a mold disposed on a machine line, and a filter 6 is set on the acrylic plate. The reason for setting the acrylic plate and the filter 6 is the same as in the second and third embodiments.
[0082]
  Subsequently, a predetermined amount (for example, half of the total amount) of the mixture including the polymer water-absorbing material 8 formed in the first embodiment is filled into the mold.
[0083]
  Subsequently, the mixture filled in the mold is spread using a trowel or the like and molded.
[0084]
  Thereby, the polymer water-absorbing material layer 10 including the polymer water-absorbing material 8 is formed.
[0085]
  Subsequently, a predetermined amount (for example, half of the total amount) of a mixture of the carbide 3 and the cement 4 that does not include the polymer water-absorbing material 8 formed in the first embodiment is filled into the mold.
[0086]
  Subsequently, the mixture containing the polymer water-absorbing material 8 filled in the mold is spread and shaped using a trowel or the like. Thereby, the porous layer 19 is formed on the surface of the polymer water-absorbing material layer 10.
[0087]
  Subsequently, a pressure plate coated with an oil component is set on the formed mixture (mixture not including the polymer water-absorbing material 8). The pressure plate is set for the same reason as in the second and third embodiments.
[0088]
  Subsequently, the mixture is pressurized at a predetermined pressure. The pressure at this time is set to the same pressure as in the second and third embodiments.
[0089]
  Subsequently, the acrylic plate is pushed upward by hydraulic pressure, so that the mixture retained in the mold is removed from the mold to obtain the panel body 2.
[0090]
  According to the fourth embodiment, it is possible to manufacture the panel body 2 in which the polymer water-absorbing material layer 10 is formed on one side and the porous layer 19 is formed on the other side (see FIG. 4).
[0091]
  Since this panel body 2 is provided with the polymer water-absorbing material 8 on one side, when the panel body 2 is laid in, for example, a greening site, the polymer water-absorbing material layer of the panel body 2 is placed on the bottom side of this greening site. By arranging 10, the water stored in the greening site can be absorbed and retained by the polymer water-absorbing material layer 10 reliably and satisfactorily.
[0092]
  Since the fourth embodiment is as described above, the polymer water-absorbing material layer 10 formed on the one surface side of the panel body 2 can absorb and retain moisture well. For example, the one surface side of the panel body 2 has more moisture. By using it in a place where it can easily come into contact with water, it is possible to exhibit even better water absorption (water retention).
[0093]
  In the first embodiment to the fourth embodiment, the product: Glass Power G-300 manufactured by Kurita Kogyo Co., Ltd. was adopted as the polymer water-absorbing material 8, but the effects as the water-absorbing material can be exhibited well. As long as it is a thing, you may employ | adopt suitably other than that, for example, you may employ | adopt the brand name: HT-50AA by a Habix company. Further, when adopting the trade name: HT-50AA manufactured by Habix Co., Ltd., the HT-50AA is disposed on an adhesive tape material or the like, and the tape material or the like on which the HT-50AA is disposed. The panel body in which the polymer water-absorbing material layer is formed on the intermediate part or one surface side of the panel body as described in the third embodiment or the fourth embodiment May be formed.
[0094]
    Example 5
  In the fifth embodiment, as shown in FIG. 5, a panel body 2 manufactured for greening by any one of the second to fourth embodiments is disposed on the rooftop 1, and this panel body for greening is arranged. This is a technique for greening the rooftop 1 using 2 as a drainage layer.
[0095]
  That is, a porous panel body 2 composed of a plurality of granular carbides 3, cement 4, a neutralizing material, a polymer water-absorbing material 8, and water is adopted as the panel body 2, and this panel body 2 is laid on the roof 1. Subsequently, the soil 7 is laid above the panel body 2 and the plant 12 is vegetated with the soil 7.
[0096]
  The panel body 2 may employ a material to which a thickener is added. At this time, the amount of the thickener is 1 m of carbide.^ThreeIt is better to set it to 0.8 kg or less. This is carbide 1m^ThreeThis is because when the amount is more than 0.8 kg, the viscosity increases so that it becomes difficult to handle.
[0097]
  The greening of the rooftop 1 first forms a partition wall 5 by surrounding a portion to be greened on the rooftop 1 with a frame formed of concrete or a synthetic resin panel or the like.
[0098]
  A drain hole 30 is provided at a predetermined location of the partition wall 5 for discharging excess water to the outside of the greening site when excessive water is supplied to the greening site.
[0099]
  Subsequently, a waterproof sheet 9 is laid in the partition wall 5, and any one of the panel bodies 2 manufactured by the manufacturing method described in the second to fourth examples is laid on the waterproof sheet 9. In the fifth embodiment, the panel body 2 manufactured in the second embodiment, that is, the panel body 2 containing the polymer water-absorbing material 8 as a whole is laid.
[0100]
  The thickness of the panel body 2 is set to 2 cm to 5 cm.
[0101]
  Further, the panel body 2 is set in a rectangular shape in plan view with one side of several tens to several hundreds cm.
[0102]
  The filter 6 of the panel body 2 is located on the upper part of the panel body 2. As described above, the filter 6 is for preventing the soil and sand of the cultivating soil 7 disposed on the filter 6 from flowing into the panel body 2 and causing clogging.
[0103]
  A culture soil 7 is disposed on the filter 6, and plants 12 are vegetated with the culture soil 7. The thickness of the soil 7 is preferably set to about 5 mm to 200 mm.
[0104]
  When the plant 12 is vegetated with the soil 7, the root of the plant 12 reaches the panel body 2.
[0105]
  In the figure, reference numeral 11 denotes a drain port (drain pipe), 13 denotes a wall portion provided around the rooftop 1, and 14 denotes a handrail.
[0106]
  According to the fifth embodiment, when raining, this moisture soaks into the soil 7 that vegetates the plant 12, and the excess water soaked in this soil 7 passes through the filter 6 to the panel body 2. A part of the water flows into the small gap 16 (see FIG. 6) of the carbide 3 constituting the panel body 2 and is held by the carbide 3. Further, the remaining excess water is a large number of voids formed in the porous solidified panel body 2 (the voids are voids 15 of the cement 4 and voids 18 formed between the carbide 3 and the cement 4). Both of them (see FIG. 6).
[0107]
  That is, the presence of the panel body 2 drains excess water from the greening site, and only the necessary water is retained in the carbide 3, so that the plant 12 is vegetated well.
[0108]
  Further, since the panel body 2 is provided with the polymer water-absorbing material layer 10 including the polymer water-absorbing material 8, the water absorption of the polymer water-absorbing material 8 can absorb and retain more water. Become.
[0109]
  On the other hand, when the moisture in the soil 7 where the plant 12 is vegetated decreases due to the clear weather, the roots of the plant 12 planted in the soil 7 are retained in the small gaps 16 of the carbide 3 of the panel body 2. Thus, the plant 12 can be vegetated well.
[0110]
  Even if the clear sky continues for a longer period of time, as described above, the polymer water-absorbing material 8 in the panel body 2 also retains sufficient moisture, so that the plant 12 vegetated on the soil 7 Can absorb the moisture retained in the polymer water-absorbing material 8, and thus the plant 12 can be vegetated without dying.
[0111]
  Further, when fertilizer is given to the plant 12, the surplus part flows into the panel body 2 through the filter 6 and is held in the small gap 16 of the carbide 3 of the panel body 2.
[0112]
  Further, when a heavy object such as a large plant is placed on the culture soil 7, the panel body 2 having a structure in which the carbide 3 is bonded with the hardened cement 4 securely supports the heavy object, and the panel body 2 No cracks or damage will occur.
[0113]
  Since the fifth embodiment is as described above, the panel body 2 includes the carbide 3 and the cement 4 at least in an amount of the carbide 3 of 1 m.^ThreeSince the cement 4 is mixed in a proportion of 50 kg to 200 kg and solidified in a porous shape, not only can it exhibit the excellent drainage required for greening the rooftop 1, but also water retention , The effect of fertilizer and the like can be sufficiently exhibited, and the excellent load resistance can be exhibited. As a result, the roof panel 1 can be well greened and a carbide panel body excellent in practicality can be obtained.
[0114]
  Moreover, since the panel body 2 can exhibit excellent water retention capability by holding moisture in the small gap 16 of the carbide 3 well, the moisture held in the small gap 16 of the carbide 3 is absorbed by the roots of the plant 12. Thus, for example, even if it does not rain for several days, the plant 12 can be vegetated well with the soil 7.
[0115]
  In addition, since the polymer water-absorbing material 8 in the panel body 2 can also absorb and retain moisture satisfactorily, the water retained in the polymer water-absorbing material 8 is absorbed by the roots of the plant 12, for example, for a longer period of time. Even if it doesn't rain, the plant 12 can be vegetated well with the soil 7.
[0116]
  Further, since the small gap 16 of the carbide 3 of the panel body 2 can hold the fertilizer well, it reliably adsorbs excess fertilizer from the soil 7 (upper soil) and wastes the fertilizer outside the partition wall 5. Can be suppressed very well.
[0117]
  Therefore, in the greening of the rooftop 1 where the greening space is limited to a predetermined range, the water and fertilizer once given to the plant 12 can be efficiently used without waste.
[0118]
