  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described in detail with reference to the drawings. In addition, in each figure, the same code | symbol is attached | subjected to the same part or an equivalent part, and the overlapping description is abbreviate | omitted. First, a structure as one embodiment of the present invention will be described, and then a high bridge to which the structure is applied will be described.

<Structure>
As shown in FIG. 1, the structure 1 is configured such that a water retaining member 3 surrounds a peripheral side surface of a long steel pipe (rod-like body) 2. The outer diameter of the steel pipe 2 is preferably 5 to 30 cm, and more preferably 10 to 20 cm. In addition, although the mode that the steel pipe 2 is linear form extended in the illustration up-down direction is drawn in FIG. 1, the steel pipe 2 may be curvilinear or may be branched.

  Here, the water retaining member 3 is porous concrete manufactured by reusing concrete waste. The water retaining member 3 has an annular shape, and has a predetermined length along the length direction of the steel pipe 2 and a predetermined thickness along the radial direction of the steel pipe 2. The water retaining member 3 provides a scaffold for a plant body 4 to be described later to stretch while creeping along the extending direction of the steel pipe 2.

  The water retaining member 3 includes a first water retaining member 3 a and a second water retaining member 3 b having different diameters around the axis of the steel pipe 2, and these are alternately fitted to the steel pipe 2. Here, the diameter of the 1st water retention member 3a shall be larger than the diameter of the 2nd water retention member 3b. Due to the difference in diameter between the two water retaining members 3a and 3b, the ridge line in the side view of the structure 1 has an uneven shape.

  The shape of the water retaining member 3 when viewed from the axial direction of the steel pipe 2 is a perfect circle, and its outer diameter is preferably 10 to 40 cm, and more preferably 15 to 30 cm. Moreover, it is preferable that the difference of the outer diameter of the 1st water retention member 3a and the 2nd water retention member 3b is 1-10 cm, and it is more preferable that it is 2-6 cm from a viewpoint of improving water retention.

  The water retention member 3 can store water by its water retention capacity. The water stored in the water retaining member 3 gradually flows toward the lower part of the structure 1 and is supplied to the plant body 4 or evaporated. As the water retaining member 3, unglazed clay can be used in addition to porous concrete, or a fiber material can be wound around.

  The structure 1 includes an illumination tool 5 for illuminating the plant body 4. The illuminating device 5 has an annular shape so as to be fitted to the steel pipe 2, and is fitted at any position where the water retaining members 3a and 3b are connected. As a kind of the lighting fixture 5, it is LED, for example. A wiring 6 for supplying electricity to the luminaire 5 is passed through the steel pipe 2 and is connected to the luminaire 5 through a hole or slit opened in the steel pipe 2. As a power source for the lighting fixture 5, it may be supplied from the outside, or a solar cell panel may be attached to the structure 1 and self-supplied.

  As a method for producing the structure 1, there is a method in which the annular water retaining member 3 and the annular illumination device 5 are sequentially fitted into the steel pipe 2. The ring shape of the water retaining member 3 and the illuminating device 5 is not necessarily integral, and two semicircular members may be connected to form a ring. In particular, when the steel pipe 2 is curved or branched, a method of connecting two semicircular ones is preferable.

  As shown in FIG. 1, the plant body 4 can extend on the surface of the structure 1 so as to crawl. The plant body 4 is preferably grown from the surrounding ground on which the structure 1 is provided, and can be extended while stretching the root of the surface of the water retaining member 3, for example, ivy.

  In the structure 1 described above, the plant body can crawl using the water retention member 3 as a scaffold, and the water retained in the water retention member 3 by receiving rainwater or the like is supplied to the plant body 4 in an appropriate and continuous manner. The Therefore, since the plant body 4 can thrive on the structure 1, if this structure 1 is installed in the arbitrary places of a town, the beauty | look can be given to a landscape. Since the structure 1 is a simple rod-like structure, it has high versatility, and can be set up in various facilities such as parks or near buildings to green the town.

  At this time, when the structure 1 is erected in the vicinity of the building, not only the beauty can be given, but also an effect of relaxing the sun, a fireproof coating or a fire spread prevention effect at the time of fire can be expected.

  Moreover, according to the structure 1, the mitigation effect of the heat island phenomenon can be expected by retaining and cooling the surrounding environment by transpiration of water by the plant body 4 and the water retaining member 3, and the air purification by the carbon dioxide absorption capacity of the plant body 4 can be expected. The effect can also be expected. In addition, sound insulation and sound absorption effects by the plant body 4 can be expected.

  Further, since the water retaining member 3 is covered with the plant body 4, the surface deterioration of the water retaining member 3 can be prevented. For example, the plant body 4 makes it difficult for sunlight to be directly applied to the water retaining member 3, and the temperature change on the surface of the water retaining member 3 can be reduced. Therefore, deterioration due to expansion and contraction of the water retaining member 3 accompanying a temperature change can be mitigated. In addition, the deterioration of the water retaining member 3 due to ultraviolet rays, acid rain, or the like can be alleviated.

  Moreover, since the structure 1 is equipped with the lighting fixture 5 which illuminates the plant body 4, it can produce the structure 1 brightly by illumination in the shade and at night, and also the growth of the plant body 4 which grows thickly. Can be used.

  Moreover, since the wiring 6 which supplies electricity to the lighting fixture 5 is let the inside of the steel pipe 2 pass, and it is not conspicuous in appearance, it is preferable in view.

  Further, the water retaining member 3 has a ridge line in the side view of the structure 1 in which the diameter around the axis of the steel pipe 2 is different in the extending direction of the steel pipe 2 by the first water retaining member 3a and the second water retaining member 3b. Since it becomes uneven | corrugated shape, resistance will arise when water flows along the structure 1, and the water retention power of the water retention member 3 improves.

  In the above embodiment, the diameter of the water retaining member 3 is different in the extending direction of the steel pipe 2 depending on the first water retaining member 3a and the second water retaining member 3b. It is good also as an aspect from which a diameter differs in the circumferential direction. That is, the shape when the water retaining member 3 is viewed from the axial direction is not a perfect circle but may be a shape having irregularities. Moreover, the kind and shape of the lighting fixture 5 are not limited to the above. Moreover, in the said embodiment, although the steel pipe 2 which is a tubular body was shown as a rod-shaped body, it does not need to be a tubular body. In this case, the wiring 6 covers the surface of the structure 1.

  Further, the structure of the present invention may include a dish-like member that surrounds the peripheral side surface of the steel pipe 2. As shown in FIG. 2, the structure 1 </ b> A includes a dish-like member 7 that can store water between the water retention members 3. As a material for the dish-like member 7, unglazed clay, fiber reinforced plastic, stainless steel, or the like can be used. Since the structure 1A includes the dish-like member 7, a larger amount of water can be stored. Water that has overflowed the capacity of the dish-like member 7 is transmitted downward to the structure 1A.

<Bypass>
The high bridge to which the structure 1 is applied will be described.

  As shown in FIG. 3, the viaduct 10 includes, for example, a floor slab 11 that provides a portion on which a vehicle runs on an expressway, and a pier 12 that stands on the ground and supports the floor slab 11. A plurality of piers 12 are erected in the direction in which the road extends.

  The floor slab 11 has side grooves 11a and 11a on both sides of the upper surface. In addition, a substantially square steel plate 11b is attached to a region of the lower surface of the floor slab 11 centering on a portion supported by the pier body 12a. That is, the pier 12 supports the floor slab 11 via the steel plate 11b.

  The pier 12 has a pier main body 12a that extends from a base portion F provided in the basement to the ground portion and has a T-shape in front view, and a structure 1 that is fixed to the lower surfaces of the pier main body 12a and the floor slab 11. Yes. The pier body 12a has a square shape in cross section as shown in FIG. 4, and a steel plate 12b is wound for reinforcement.

  Here, the structure 1 has a curved shape, and a total of eight structures are arranged per two pier main bodies 12a, two for each of four circumferential surfaces of one pier main body 12a. The eight structures 1 are embedded in the foundation portion F in the ground of the pier body 12a and extended upward (see FIG. 3), and after being fastened to the steel plate 12b wound around the pier body 12a, Centering on the vertical axis of the main body 12a, each of the main bodies 12a extends radially and extends to the steel plate 11b attached to the lower surface of the floor slab 11 (see FIG. 4). That is, each structure 1 extends so as to connect the side surface of the pier body 12 a and the lower surface of the floor slab 11.

  Of the four peripheral surfaces of the pier body 12a, two structures 1a and 1a (hereinafter referred to as first structures) arranged on the surface facing the direction in which the floor slab 11 extends are as follows. An arch structure is formed between the adjacent pier main bodies 12a and 12a. That is, the two structures 1a and 1a are the same members as the two structures 1a and 1a disposed on the facing surfaces of the adjacent structures 1, and both ends of the two pier bodies 12a are different from each other. It is buried up to the foundation part F in the ground, and its central part constitutes the top of the arch structure.

  On the other hand, of the four surfaces of the pier body 12a, two structures 1b and 1b (hereinafter referred to as second structures) arranged on surfaces parallel to the direction in which the floor slab 11 extends are floors. After being fastened to the steel plate 11b attached to the lower surface of the plate 11, it is terminated in the air.

  The 1st structure 1a and the 2nd structure 1b are connected by the 3rd structure 1c so that these can mutually pass water in each binding part in steel plate 11b. In other words, the structure 1 as a whole has a branched structure.

  As shown in FIG. 3, each of the side grooves 11a of the floor slab 11 has a portion provided with a hole 11c, and the second structure 1b is located below the hole 11c. That is, the side groove 11a and the second structure 1b are connected so that rainwater or the like accumulated in the side groove 11a is supplied to the second structure 1b through the hole 11c.

  In the viaduct 10 shown above, since the structure 1 functions to reinforce the viaduct 10, the viaduct 10 can be reinforced (for example, reinforcement for earthquake resistance) while giving a beautiful appearance to the cityscape. In addition, since the structural body 1 extends so as to connect the pier body 12a and the lower surface of the floor slab 11, the pier body 12a and the floor slab 11 are reinforced with each other, and the strength of the viaduct 10 is increased. .

  Further, since the structure 1 is connected to the floor slab 11 so that rainwater on the floor slab 11 is supplied from the floor slab 11, rainwater on the floor slab 11 is supplied to the structure 1. At this time, rainwater is guided downward while passing through the surface of the structure 1 and providing water to the water retaining member 3. Rainwater stored in the water retaining member 3 is used for the growth of the plant body 4.

  Here, since the 2nd structure 1b is located under the side groove | channel 11a, it can receive rainwater directly, but the 1st structure 1a cannot receive rainwater supply directly. Rainwater is also supplied to the first structure 1a by the third structure 1c that connects the first structure 1a and the second structure 1b.

  Moreover, since the structure 1 in the viaduct 10 has an arch structure that passes between the plurality of pier main bodies 12a, 12a, the degree of reinforcement of the viaduct 10 is further increased by the arch effect.

  And in the viaduct 10 shown above, the underpass space becomes like a tree-lined road due to the presence of the structure 1 that extends like a tree, and is expected to be used as a promenade. Moreover, the urban environment where a human and animals and plants coexist is created by the landscape and environment which the plant body 4 gives.

  In addition to the embodiments shown above, the highly crosslinked structure of the present invention may be the following embodiments. That is, as shown in FIGS. 5 and 6, the viaduct 20 includes a plurality of viaducts 10 that run side by side, and the structure 1 (herein, the second structure 1 b) is between the plurality of viaducts 10 and 10. It is good also as an aspect which has the arch structure to pass. In this case, the degree of reinforcement of the viaduct 20 is further increased by the arch effect. It also contributes to the greening of the space equivalent to the median strip.

  The highly crosslinked structure of the present invention is not limited to the above embodiment. For example, in any of the above-described embodiments, the mode in which the entire viaducts 10 and 20 are reinforced by the structure 1 is shown. However, the structure 1 can be attached only to the pier body 12a and only the pier body 12a can be reinforced. In addition, the floor slab 11 can be directly reinforced by extending the structure 1 from the ground to the lower surface of the floor slab 11.

  Moreover, it is good also considering the surrounding part in which the pier main body 12a is embed | buried as the land which can be planted. Since the water transmitted from the upper part of the structure 1 gathers in the peripheral part in which the pier main body 12a is embed | buried, water can be supplied with respect to the plantable land.
