JP 2009-278924 A JP 2008-29322 A JP-A-2005-261208 Japanese Patent No. 4299943 Japanese Patent No. 3945711

            Most conventional wall greening structures require an irrigation device, which requires complete conditions for peripheral equipment such as water supply and drainage facilities and electrical facilities, and the wall greening structure becomes complicated due to the function and structure of the irrigation device. Also occurs excessively. It cannot be freely selected in various places, the installation place is limited, and maintenance costs related to irrigation equipment and peripheral facilities are necessary.

            Many of the conventional wall greening structures are mesh structures such as wire rope, steel frame structures, board structures made of ALC, aluminum, foamed polystyrene, etc. Wall greening is completed over the growing period, and when the wall greening structure installation is completed, there is no green volume by the plant to cover the wall greening structure, and plant growth immediately after the wall greening structure installation However, because the wall greening structure itself is exposed, the artifacts are conspicuous and the inorganic texture cannot be denied. In addition, the growth direction is left to the plant, and it is difficult to form the intended greening shape.

             Next, most of the conventional wall greening structures are made of artificial soil or organic material as the material of the vegetation base material, and it is necessary to take measures such as countermeasures against deterioration of the planting base material body due to secular change and replenishment / compensation. It is necessary to take measures against contamination on the installation object and the surrounding area.

            The conventional wall greening structure is made to order according to the standard specifications or each local condition, so if the wall greening structure is processed or changed in shape due to a plan change at the construction site, prompt response is possible. It is difficult and expensive.

            In terms of contribution to buildings and the surrounding environment, the contribution is large depending on the growth situation of the plant immediately after the installation of the wall greening structure in order to reduce the influence of solar heat etc. due to the overgrowth effect of the plant. It depends.

            In the wood wall greening panel, the structure on the front of the panel has a reverse armored shape that can receive rainwater, etc., receives water from the top of each component board and the wood wall greening panel, and absorbs water on the vegetation base material provided inside the panel Let

The vegetation base material absorbs water below the specified temperature ( temperature sensing point) and swells in a gel form. When the temperature exceeds the temperature sensing point, the resin that discharges the absorbed water is dispersed and molded. An environment where plants can grow in rainwater etc. is constructed by using a water storage / water mat with high water storage / water supply capability and the ability to repeat water storage and water supply according to changes in temperature. This effect eliminates the need for irrigation devices and peripheral facilities, increases the degree of freedom of installation location, and eliminates the need for maintenance costs and regular maintenance of the irrigation devices.

Furthermore, temperature sensitive water feedwater mat is vegetation based material, because the volume change at the time of water absorption and drainage does not occur substantially, not substantially cause almost no growth inhibition to be broken or to compress the roots of the plant.

            In woody wall greening panels, the components on the front of the panel are impregnated with thinned wood such as glyoxal resin to improve the performance of the wood, such as dimensional stability, decay resistance, and ant resistance. By using the tension plate, the root growth path of the plant is guided to the top edge of the component plate, and the growth is induced. In addition, because the shape and area of the planting part, which is a notch opening provided in each part of the component board, can be easily changed and set with a general-purpose tool, etc., the arrangement of plants and the The amount can be set freely, so it is possible to quickly form a green surface, and it is possible to construct a green landscape immediately after installation. Can be configured.

The plant used for the wooden wall greening panel is a non-soil-growing product with no soil attached to the roots of the plant grown by hydroponics, and the temperature-sensitive storage / water mat that is the vegetation base material itself is made of an inorganic material. there therefore, less and quality deterioration and volume reduction, suppressing the sewage occurrence of muddy water.

The wood wall greening panel is composed of wood impregnated with glyoxal resin, etc. and a temperature-sensitive water storage mat, so that on-site processing and shape change can be easily performed with general-purpose tools and occurs at the construction site. It is possible to respond quickly to unforeseen changes.

            As an effect on the environment of building wall greening, as a result of the survey on the “Wall Greening” of the Tokyo Metropolitan Industrial Labor Bureau Agricultural and Forestry Experiment Station, there are concrete walls, walls with plants hanging on the wall, and walls with vegetation base materials in close contact with the wall. In the three types, the wall surface temperature rise of the wall to which the vegetation base material is closely attached is the lowest, and the result that the wall surface temperature difference is a maximum of 10 ° C. (as of 15:00 on September 10) has been announced, Due to its structural characteristics, the wooden wall greening panel is made of a material with low thermal conductivity, and since it contains moisture, it has high heat shielding properties, and the density of greening plants can be set freely, so the wooden wall greening panel Immediately after installation, the temperature rise of the building wall can be suppressed. Furthermore, there is an effect of suppressing the surrounding air temperature rise in front of the wooden wall greening panel, and cool wind is generated around the front surface of the wooden wall greening panel.

              In this way, unlike the conventional wall greening structure, the wooden wall greening panel has a reverse armoring shape on the front of the panel and a vegetation base of a temperature-sensitive water storage / water mat that has a high water storage / supply capacity inside the panel. In addition to reducing installation costs and maintenance-free equipment, the plant has a structure that can secure the growth induction path of plant adsorption roots and set the planting location and area, and is an inorganic structure. Immediately after installation, a peaceful and warm person-friendly landscape can be constructed, and the wall surface of the building and the surrounding environment have the effect of suppressing the rise in wall temperature and mitigating the rise in ambient temperature. Contributes greatly to providing habitat and urban environment.

           Hereinafter, embodiments of the present invention will be described with reference to FIGS.

The present embodiment relates to a wooden wall greening panel that greens the outer wall of an outdoor building and the exterior (such as a fence / fence) such as a detached house or a cityscape.

              The front of the panel (1 in the figure) was impregnated with, for example, glyoxal resin, which has a track record of improvement in wood performance such as dimensional stability, decay resistance, and ant resistance, with no change due to deterioration after 15 years. Due to the effect of the reverse armoring of the component board using the plate (1a in the figure), rainwater is received from the upper edge of each component plate ((1) in the figure) and the top of the panel, and the vegetation base inside the panel A temperature-sensitive water storage mat (2 in the figure) absorbs and retains water, and several levels are set for the temperature outside the drainage of the temperature-sensitive water storage mat (2 in the figure) depending on the outside temperature and plant growth. By doing so, the plant supplies the necessary moisture when needed,

            At the top of the panel (1 in the figure), the top edge of each component plate ((1) in the figure) is the growth path of the adsorbed roots of the planted plant due to the wood being made of wood, and attracts the adsorbed roots of the planted plant It has an effect, induces the growth direction of the plant, promotes the growth, and systematically forms a green area at an early stage.

            The width of the component plate (1a in the figure) on the front of the panel (1a in the figure) can be set according to the installation location and various situations, and the thickness dimension of the component plate (1a in the figure) Although it is an experience value from those who handle timber, it is said that approximately 1/5 or more of the composition board width is preferable, and if it is less than that, warping will easily occur on the board, and cracks and deviation will occur, but not much If it is too thick, it becomes heavy and inefficient and uneconomical. For example, if the component plate width is 10 cm, it will be 2 cm or more, and if the component plate width is 20 cm, it will be 4 cm or more.

            In addition, by reducing the width of the component plate (1a in the figure), the upper edge of the component plate ((1) in the figure), which is the surface that receives rainwater, etc. is increased to increase water receiving efficiency, and thinning with an upper limit on the plate width The use of wood and other materials can be promoted, resources are effectively used, and environmental measures are taken.

The temperature-sensitive water storage mat (2 in the figure), which is the vegetation base, has a maximum water holding capacity of 900L / m3 or more, a high water storage / water supply capacity of 90% or more of the mat volume, and a function to repeat water storage and water supply according to changes in temperature. A porous light-weight inorganic material such as perlite with a ventilation layer (5 in the figure) as a water rot prevention measure on the inner side lower surface of the bag, which is inserted into a bag-shaped water shielding layer (3 in the figure) having an upper opening . Etc. are provided on the lower and side surfaces of the bag. The water-blocking layer itself absorbs external moisture and does not release moisture inside.It has a water-absorbing and waterproofing performance.For example, a water-absorbing sheet is processed and used to effectively transfer external moisture to a temperature-sensitive water storage and supply mat. Take measures to prevent water from being constantly moistened while absorbing water.

              In the planting part (6 in the figure) provided by cutting out on the component panel (1a in the figure) on the front of the panel, a water shielding layer is formed with a blade or the like from the panel planting part notch opening (6 in the figure) during planting. Through (3 in the figure), cut into the temperature-sensitive water storage mat (2 in the figure) that is the greening base, and plant the plant so that the plant roots are sandwiched in the temperature-sensitive water storage mat. As a result, the plant is firmly stabilized and the root of the plant is settled on the temperature-sensitive water storage / water supply mat and does not fall off.

In consideration of workability and transportation, the size of the panel itself is set to use cedar wood with a thickness of 1.5 cm (1a in the figure) on the front panel of the panel. Thickness 1.5cm x 1000 = 5.7kg / m2, and when the temperature sensitive water storage mat (2 in the figure) is 5cm thick, the specific gravity of urethane 0.06 x thickness 5.0cm x 1000 = 3.0kg / m2, and the total dry weight of the panel (7 in the figure) is about 10kg / m2, so the standard panel is about 2m2 and a half panel of about 1m2 is also available. Also good.
From this, the wood wall greening panel height is 0.9 m × width 1.8 m, 16.2 kg / sheet, panel height 0.9 m × width 0.9 m is 8.1 kg / sheet, Even when the panel height is 1.8 m × width is 1.8 m, it is 32.4 kg / sheet.

            When attaching to the building, install a root-prevention layer (4 in the figure) between the building and the panel, and take great care to prevent plant roots from sticking to the building and adversely affecting the building. At the position of the panel trunk edge (7 in the figure), the type and position of the mounting bracket are set according to the situation of the building. The mounting bracket can be easily made by an existing method such as anchor bolt mounting (10 in the figure) according to the type and situation of the building.

            In addition, when installing wooden wall greening panels continuously, a panel trunk edge connection part (8 in the figure) is provided to make the panel trunk edges a phase-separated form so that the mounting brackets do not overlap efficiently and landscape The mounting shape should be considered.

            When installing outside a building (such as a detached house) such as a detached house or a cityscape in a cityscape, either the same shape as the front of the panel (Fig. 6) can be used as the back material on the back of the panel. Use a horizontally long plate shape (Fig. 7) and install it according to the surrounding situation, application, and demand.

            About the connection form, a panel body edge connection part (8 in the figure) is provided, and the panel body edges are connected to each other, and the panel body edges are similarly connected to each other in the corner part.

            For mounting and fixing, the panel same edge (7 in the figure) and the panel trunk edge connecting part (8 in the figure) and the lower part are extended to the lower part, and fixed and self-supported by an existing fixing method according to the embedding condition.

            As an effect on the environment of building wall greening, in a private company (Naturoch Japan Co., Ltd.) experiment, the wall thickness and ceiling thickness were reduced according to the scale of a general building in a miniature model of a concrete building. When the same model and the same model are both greened with lava panels, the temperature change verification results inside both models show that the temperature inside the concrete model is 44.3 ° C and the temperature inside the entire greening model is at 36.7 ° C. The temperature difference became 9 ° C. at 35.3 ° C.

            In addition, in the Metropolitan Expressway 1/35 model, the side wall of the road model is 43.4 ° C on the wall side of the soundproof wall when the outside air temperature is 31 ° C in a comparative verification between the soundproof wall (metal) and the greening wall (stone). 42.3 ° C was recorded on the central lane side of the same soundproof wall, 39.8 ° C was recorded on the green lane wall side, and 36.3 ° C on the central lane side of the green wall, resulting in a maximum difference of 6 ° C. Is published.

            In addition, in the Tokyo Metropolitan Industrial Labor Bureau Agricultural and Forestry Experiment Station “Wall Planting” survey, the effectiveness of a wall in which vegetation base materials are closely attached to a concrete wall has been announced. The material with low thermal conductivity is composed of a combination of 0.12 w / m · k for cedar and oak wood and 0.023 to 0.026 w / m · k for urethane. Compared to 0.2w / m · k of lava, the wooden wall greening panel has a thermal conductivity of 60% or less, so it has high heat shielding properties, making it difficult to transmit solar heat to the building.

Examples of thermal conductivity (w / m · k) of typical materials are shown below.
Steel material 53.0 SUS material 15.0 Aluminum material 200.0
Concrete 1.6 ALC panel 0.17
Dairiishi 3.0 Lava (Pumice) 0.2
Wood (wood, cedar) 0.12
Rigid urethane foam 0.023-0.026

            Furthermore, since the density of greening plants can be set freely, the temperature rise of the building wall can be suppressed immediately after the installation of the wooden wall greening panel, and the surrounding air temperature rise suppression effect at the front of the wooden wall greening panel A cool wind is generated and the low temperature range spreads, thereby suppressing the temperature rise.

            The wood wall greening panel itself has high heat insulation, the temperature rise of the walls of buildings, etc. is suppressed, and the surface temperature difference between the year and day becomes small, so the shrinkage expansion due to the temperature difference becomes small, and the deterioration due to secular change By reducing the life of the building, the lifetime of the building is prolonged. Moreover, since the outer wall of the building is covered with a wooden wall greening panel, the direct influence of external factors such as ultraviolet rays and acid rain is reduced.

            In addition, as the name suggests, the wooden wall greening panel uses a wood material on the front surface, so it can also be expected to have soundproofing and reverberation effects. Greening also has the effect of preventing graffiti on the wall and maintaining the beautification of the cityscape.

          Although this embodiment was described above, it shows in FIGS. 9-12 (reference photograph) as a practical example. By installing a woody greening panel in such a form, the cityscape is formed into a good one.
