  The first to third embodiments of the present invention are porous holes employed in new construction / landscape construction of concrete structures such as tide and sabo landscaping, landscape construction of steel sheet piles, steel pipe sheet pile revetments, and ecosystem development construction. This is a scenic panel using high quality natural stone, and lava is used as porous natural stone. Here, the scenery is to restore the scenery. The characteristics are summarized as follows.

  First, preserve the ecosystem. The surface of this landscape panel has a porous structure that makes it easy for living creatures in the natural world to live, so plants such as microorganisms, bryophytes (mosses, ferns), and flowers tend to adhere, and the ecosystem over time Let me recover. As a result, the structure surface does not block the ecosystem. In addition, a water purification effect can be expected near the waterside.

  Second, it shows beneficial environmental performance. The porous environment, which is the feature of this landscape panel, is excellent in moisture absorption and heat insulation, so it can reduce the reflection and humidity under the sun, prevent dryness in the winter, and contribute to the mitigation of the heat island phenomenon.

  Third, workability is good. Ultra-lightweight and ultra-thin panels, and a construction method that covers the surface without breaking existing structures, reducing waste materials due to demolition work, and can be constructed in a short period of time without the need for heavy machinery, thus reducing the overall construction cost be able to. There is also a variety that can be applied anywhere, such as concrete, iron, aluminum, and wood.

  Hereinafter, each embodiment will be described in detail.

  FIG. 1 is a diagram showing a configuration of a landscape panel according to the first embodiment of the present invention. Specifically, FIG. 1A is a plan view of a landscape panel, FIG. 1B is a top view of the landscape panel, and FIG. 1C is a side view of the landscape panel. The landscape panel 1 is particularly thin and light because a lava gravel (scoria) 3 is disposed on a panel substrate (cement board) 2 made of a cement-based hardened body or the like and the entire substrate is covered. And the panel 1 based on gray brings on the calm appearance immediately after construction. Although there are few irregularities, ferns, moss, and climbing plants can grow. Underwater microorganisms can live in the water. The landscape panel 1 has a height d1 of, for example, a maximum of 10 mm.

  FIG. 2 is a diagram showing a configuration of a landscape panel according to the second embodiment of the present invention. Specifically, FIG. 2A is a plan view of the landscape panel, FIG. 2B is a top view of the landscape panel, and FIG. 2C is a side view of the landscape panel. The landscape panel 11 is thin and light because a lava slice 13 and lava gravel (scoria) 14 are disposed on a panel substrate (cement board) 12 made of a cement-based hardened body or the like and the entire substrate 12 is covered. The panel based on the deep brown color creates a calm appearance. There are irregularities and gaps, and ferns, mosses, and climbing plants can grow. Insects can be moved. In addition, underwater microorganisms and aquatic organisms can live in the water. Note that the height d2 of the landscape panel 11 is, for example, a maximum of 20 mm.

  FIG. 3 is a diagram showing the configuration of a landscape panel according to the third embodiment of the present invention. Specifically, FIG. 3A is a plan view of the landscape panel, FIG. 3B is a top view of the landscape panel, and FIG. 3C is a side view of the landscape panel. The landscape panel 21 has a lava 23 and lava gravel (scoria) 24 disposed on a panel substrate (cement board) 22 made of a cemented hardened body or the like, and the entire substrate 22 is covered. And the panel based on deep brown gives the natural appearance of lava stone. The unevenness and gaps are large, and ferns, moss, climbing plants and small plants can grow. In addition, small animals such as snakes can be moved even on the straight wall. Aquatic plants, underwater microorganisms and aquatic organisms can live in the water. The landscape panel 21 has a height d3 of, for example, a maximum of 80 mm.

  Here, “Lava” is collected from Miyakejima, Oshima, Mt. Fuji, and Mt. Asama. The lava collected at Miyakejima, Oshima, and Mt.Fuji are all basaltic, but the lava collected at Miyakejima and Oshima are solidified after being scattered in the air by an eruption, so there are multiple fine holes. It is vacant porous. On the other hand, lava collected at Mt. Fuji is hardened after flowing as a lava flow, so there are few holes, but on the other hand, it can be finely crushed. Therefore, in the first to third embodiments, lava stones collected at Miyakejima and Oshima are adopted. However, it is not limited to this.

  Since such lava is porous, it becomes a habitat for small animals, microorganisms, etc. (ecosystem conservation and recovery effect). In addition, the inorganic structure is greened appropriately and harmonizes with the surroundings over the years (landscape, scenic effect). In addition, it becomes soil to grow moss, ground ratio and ivy (greening effect). Further, since it is porous, it can be expected to have wettability and water retention and water purification action at the water (wetability and water purification effect). Furthermore, sound can be absorbed by the porous structure (sound absorbing effect). In addition, the fine irregularities of the lava prevent light reflection, and the extremely small voids also have a heat blocking effect (light reflection preventing effect). Also, negative ions are generated from lava (negative ion effect). In addition, graffiti cannot be done because the surface is porous and uneven (doodle prevention effect). And the deterioration of the structure surface can be prevented by sticking (protection of the structure surface). In addition, because there is no space for large roots, plants do not grow large and maintenance can be minimized (low maintenance costs). Since each embodiment employs lava, the above-described effect is also provided in each embodiment as it is.

  Moreover, the brightness can be made 6 or less by using the lava. Here, with regard to “lightness”, the “Disaster Restoration Basic Policy for Protecting Beautiful Mountains and Rivers” was revised in April 2014, and the lightness guideline (below 6) and the lightness measurement method were described. However, since measuring instruments that are not normally handled are also used, there is a concern that confusion may occur when actually measuring the brightness. Therefore, the (Public Corporation) National Civil Engineering and Concrete Blocks Association provides guidance on lightness measurement methods, etc. for product blocks often used in small and medium rivers, prepares a certificate for lightness analysis and lightness measurement results, and provides an average lightness measurement method for revetment blocks. Strive to spread. If the block material itself has a lightness of 6 or less, it is considered that the lightness is considered to be 6 or less without measuring the average lightness including joints. In addition, the measurement method for the lightness measurement combining concrete products and lava is suggested by the Public Works Research Institute Symbiosis Center. Of course, the lightness of a general stone can be measured with a known luminance meter, illuminance meter, or the like.

  Such landscaping panels according to the first to third embodiments can be used for river revetments, waterways, gutters, road slopes / retaining walls, protective fences, sound insulation / sound barriers, wellheads, dam walls, reservoir surfaces, dams, bridges.・ When installing on bridge girders, stairs / curbs, buildings, outer walls of public facilities, general buildings, streets, etc., fixing with screws or fixing with adhesive and screws can be used. According to the former fixing method using screws, it is possible to perform construction without adversely affecting the construction site, the local environment and the ecosystem. The detailed procedure of the fixing method with screws is in the order of cleaning of the construction surface, positioning, concrete drilling, fixing with screws, and screw head finishing. On the other hand, according to the latter fixing method using an adhesive and a screw, the bonding surface can be further strengthened.

  Here, with reference to FIG. 4, the attachment to the actual wall surface of the scenery panel which concerns on 2nd Embodiment is explained in full detail. As shown in FIG. 4A, when actually attached to the wall surface 32a of the concrete frame 32, a plurality of landscape panels 31 are arranged in an alternating manner in order to increase the attachment strength. Then, as shown in FIG. 4B, the landscape panel 31 is fixed to the wall surface 32a of the concrete housing 32 with, for example, screws, an adhesive or the like as described above.

  Next, with reference to the flowchart of FIG. 5, a method for manufacturing a landscape panel according to the first to third embodiments will be outlined.

  First, a panel substrate made of a cement-based hardened body or the like is formed into a predetermined size (S1), and then lava disposed on the panel substrate is crushed into a predetermined size and sliced (S2). Then, the crushed and sliced lava is mounted on the panel substrate (S3). As an attachment method, lava may be embedded in the panel substrate itself, in addition to bonding with an adhesive. After attaching lava slices at predetermined intervals, lava gravel (scoria) is attached so as to cover the plane between the lava slices (S4). In this way, the landscape panel is completed.

  In the first to third embodiments described above, a landscape panel attached to an existing building or the like has been exemplified. Next, referring to FIG. 6, as a fourth embodiment of the present invention, for a sabo dam construction or the like. The adopted sustainer panel will be described.

  6 (a) shows the state of the surface of the arranged sustainer panel, FIG. 6 (b) shows the state of the rear surface of the arranged sustainer panel, and FIG. 6 (c) shows the state of the sustainer panel for the sabo dam construction. The state of construction is shown from the side.

  As shown in FIG. 6A, the plurality of sustainer panels 41 are arranged alternately to increase the attachment strength. Then, as shown in FIG. 6B, the adjacent sustainer panels 41 are connected by connecting angles 42 and 43. Loose holes are provided in the connecting angles 42 and 43, and screws are fixed to holes formed in the respective sustainer panels 41 through the loose holes. Further, connection ankles 44 and 45 are also attached near the upper side of the uppermost panel of each sustainer panel 41 and also near the lower side of the lowermost panel. Then, as shown in FIG. 6 (c), the connecting ankle 44 near the upper side of the uppermost panel is connected to the piercing bar 47 by a wire 50 or the like and fixed so as to maintain a predetermined angle. The connecting angles 42 and 43 connecting the sustainer panels 41 are also connected to other stabs 48 by wires 51 and 52 and the like. The connection angle 45 provided on the lower side of the lowermost panel is connected to the pedestal piercing line 49 via the gantry angle 49.

  According to the first to fourth embodiments of the present invention, the following effects are exhibited.

  (1) The landscape panel according to the embodiment of the present invention is a civil environment remodeling material in which a porous natural stone is combined based on a thin base. This panel can be said to be a global warming countermeasure product that can be entrusted with the protection of the ecosystem and environmental purification because a wide variety of microorganisms existing in the construction area adhere to and grow and form a biological community.

  (2) Because the landscape panel is a concrete base panel whose surface is covered with porous natural stone, the product is thin and light, so it can be installed by manpower and the scaffolding can be simplified. The workability is improved.

  (3) Since the surface of the landscape panel is covered with porous natural stone, the brightness and color can be suppressed, so that harmony with the surrounding environment is achieved.

  (4) The landscape panel is excellent in water permeability, air permeability, and water retention by utilizing porous natural stone, and therefore, it is possible to ensure an environment necessary for animal and plant habitat and growth.

  (5) Since the scenery panel uses porous natural stone, it has excellent adsorption action, and a microbial feeding area and a habitat for living organisms that use it are formed. Moreover, the adsorbed substances are decomposed by the action of microorganisms, and a water purification effect around the construction site can be expected.

  (6) In addition to the above, in porous river revetments, road retaining walls, and concrete jungles, the porous environment can connect the separated natural environment and realize barrier-free ecosystems.

(Industrial applicability)
The use of landscape panels according to the first to third embodiments includes river revetments, waterways, gutters, road slopes / retaining walls, protective fences, sound insulation / sound barriers, wellheads, dam walls, reservoir surfaces, dams, bridges・ There are bridge girders, stairs / curbs, buildings, external walls of public facilities, general buildings, townscapes, etc.

  As described above, by covering a river bank, a waterway, a road retaining wall, and the like with a landscape panel according to an embodiment of the present invention, a civil engineering structure that resonates with the surrounding natural environment is reborn. The uneven wall surface, which is a composite of natural porous materials, will be greened appropriately, so it will harmonize with the natural landscape. Dirt and unevenness do not start to stand out as time passes like conventional concrete structures, and wall greening mainly consists of moss and shallow root plants, so it does not grow excessively and maintenance is necessary Absent. In the water area, the porous environment plays the role of a filter medium, contributing to water purification.
