  BEST MODE FOR CARRYING OUT THE INVENTION The best mode for carrying out the present invention will be described based on an embodiment shown in the drawings.

  FIG. 1 is a perspective view of a single block showing a precast concrete greening block (hereinafter also referred to as a greening block) 1 according to a first embodiment of the present invention, FIG. 2 is a partially enlarged side sectional view, and FIG. It is a sectional side view which shows an example.

  In these figures, the block main body 2 constituting the greening block 1 is made of precast concrete manufactured at the factory, and its vertical and horizontal sizes are set as desired. For example, it is formed into a flat plate of 180 cm × 90 cm. To do. By making this block main body 2 into concrete, the intensity | strength of the vertical surface and inclined surface which attach this block main body 2 can be raised. Furthermore, the block body 2 is preferably made of porous concrete foamed using a foaming agent. Further, peat or the like may be applied to the porous concrete as described above.

  A plurality of ridges 3 are arranged in parallel on the surface side of the block body 2, that is, the surface on which the vine plant is climbed, and the ridges where the plant climbs between the adjacent ridges 3, 3. 4 is open on the surface side, and the longitudinal direction of the groove is formed along the climbing direction of the plant, and both ends 4a and 4b in the longitudinal direction of the recess 4 are open on the side of the block body 2 is doing. A plurality of the concave strips are arranged side by side.

  The concave stripe portion 4 has a climbing gap D1 between the bottom surface 4c (the surface of the block main body) and a protective bar 5 made of a metal wire penetrating the protruding stripe portion 3 is recessed. It is arranged in a direction perpendicular to the longitudinal direction of the strip 4. The climbing gap D <b> 1 is formed in such a size that a plant can pass through the bottom surface 4 c and the protective muscle 5 and climb. Further, the protective bar 5 has a single protective bar penetrating through a plurality of protruding parts 3a formed in the middle part of the block body 2, and both ends are embedded in the protruding parts 3b, 3b on both sides. Further, a plurality of the protective bars 5 are provided in parallel with a predetermined interval L1 in the longitudinal direction of the concave stripe portion 4.

  Although not shown, a reinforcing bar is arranged in the block main body 2 separately from the protective bar 4.

  With the above-described configuration, one protective bar 5 is partially exposed in each concave line part 4 provided in parallel and partially embedded in each parallel line part 3. The block main body 2 is firmly fixed to the block main body 2, and the strength of the block main body 2 is increased by the reinforcing bars 5 serving as reinforcing bars.

A method of greening using the greening block 1 of the first embodiment will be described.
As shown in FIG. 3, for example, the greening block 1 is arranged on the wall surface 6 of a building so that the longitudinal direction of the protrusions 3 and the concave stripes 4 is directed vertically, and the greening block 1 is arranged. It adheres to the wall surface 6 with suitable fixing means such as mortar and screws. Since the greening blocks 1 are formed in a predetermined size, a desired number of greening blocks 1 are arranged and fixed on the wall surface 6 in the vertical direction and the horizontal direction in a connected state.

  In this state, the plant is planted on the ground near the lower portion of the wall surface 6. When the plant 7 grows and the vine portion extends, the attached root 7b of the vine portion 7a enters and adheres to the block main body 2, and a part of the vine portion 7a is attached to the bottom surface 4c and the protective muscle in the concave strip portion 4. Climb through the climbing gap D1 with 5. In this way, when the vine portion 7a passes through the climbing gap D1, the movement of the vine portion 7a is suppressed by the protective muscle 5 and the protruding ridge portion 3 even when wind pressure is applied, and the planting plant 1 greening block 1 Is prevented from peeling or falling.

  Furthermore, since a plurality of plant protection portions and a plurality of block body embedded portions are formed in series in one protective muscle, and the block body embedded portion is embedded in the block body, the protection muscles serve as auxiliary muscles of the block body. It has a function, and the strength of the block body can be increased, and the protective muscles can be firmly provided on the block body.

  Further, by molding the block body 1 with porous concrete, the adherent root 7b of the plant 7 can easily enter the block body 2, the adhesion is increased, and the plant 7 is further prevented from being detached and dropped.

  Moreover, since the wall surface 6 is coat | covered with the block main bodies 1 made from concrete, the intensity | strength of the wall surface 6 can be improved.

  Although the said Example showed the example which attaches the greening block 1 to the wall surface 6 of a building, the greening block 1 of this invention attaches to the vertical surface and inclination surface which require greening, such as a slope mountain surface, and greens. In addition, the strength of these vertical surfaces and inclined surfaces can be increased, and the inclined ground surface can be protected.

  Further, since the greening block 1 is precast concrete manufactured at the factory, the quality can be improved, and further, since the block is of a predetermined size, it is easy to clearly distinguish the range of vegetation. It can be sold to the general public and contribute to the spread of greening.

  Furthermore, since the protective bar 5 is provided integrally with the block main body 2 at the time of manufacturing at the factory, only the work of fixing the block main body 2 to the wall surface 6 or the like is required at the construction site, and the fixing work of the protective bar 5 is not required. Construction becomes easy.

  Furthermore, by forming the block body 2 from porous concrete and applying peat or the like to the block body 2, it is possible to assist the activity of the plant or to weaken the alkali of the concrete so that it is suitable for the plant.

  Furthermore, by using a desired color such as green as the aggregate of the block main body 2, the landscape is not impaired even when a part of the plant withers.

  4 is a perspective view of a single block showing a precast concrete greening block according to a second embodiment of the present invention, FIG. 5 is an enlarged side sectional view of a part thereof, and FIG. 6 is a perspective view showing an example of a use state. .
