JP3583806B2 - Top overhanging lighting block - Google Patents

Description

[0001]
[Industrial applications]
The present invention relates to an overhanging daylighting block for providing, for example, a sidewalk or a flower bed or the like in a state where an upper side is overhanging on a waterway, and enabling daylighting on a side of the waterway.
[0002]
[Prior art]
An example of an overhanging block used on a slope to serve also as a seawall of a river is shown in, for example, Japanese Utility Model Laid-Open No. 5-67639. In order to form a waterway part below and a sidewalk part above, it is formed of concrete in a substantially Z shape. An inclined wall is provided between the waterway and the sidewalk, and a through hole communicating with the waterway is provided below the wall so that fish can enter and exit.
[0003]
[Problems to be solved by the invention]
Many conventional overhanging daylighting blocks usually do not take care of living things, but there are also some that allow fish to enter and exit as in the above example. However, by taking into account the daylighting of the waterway formed below and allowing the growth of aquatic plants preferred by organisms, the waterway can be made a more ecologically safe waterway. Although it is not an upper overhanging block, one in which a concave portion is formed in the side wall of the waterway is also seen in, for example, Japanese Utility Model Laid-Open No. Hei 3-2024. However, since there is no consideration regarding lighting, it cannot solve the problem such as the growth of aquatic plants. . The present invention is intended to provide the upper overhanging block with a function of preserving the ecosystem more, and particularly considers the lighting in the waterway.
[0004]
[Means for Solving the Problems]
In consideration of the above points, the present invention considers the above-described points, and provides a rear plate portion 2 having an upwardly projecting portion on the back portion with respect to the bottom portion 1 in order to provide an overhanging portion 18 with an upper portion projecting above the water channel; The upper overhanging daylighting block provided with a partition wall portion 3 lower than the rear plate portion 2 at the bottom, and the bottom portion 1 forms a vegetation gap 4 of fish nests and waterside plants between the rear plate portion 2 and the partition wall portion 3. None, the back slab 2 is inclined at an acute angle so that the upper part is forward at an angle that allows light to be collected into the daylighting vegetation gap 4, and the partition wall part 3 is almost directly below the upper end of the rear stencil 2. It is an overhanging daylighting block provided.
[0005]
In the upper overhanging daylighting block, it is preferable to provide a horizontal cue groove 5 or a water-permeable slit 6 below the back plate portion 2.
[0006]
Further, it is preferable that the partition wall portion 3 is provided with a hole 7 for moving organisms.
[0007]
Further, a through hole 8 may be provided in the bottom 1.
[0008]
[Action]
The upper overhanging daylighting block of the present invention allows natural light to enter the daylighting vegetation gap 4 between the back plate part 2 and the partition wall part 3, and provides favorable living conditions for aquatic vegetation and fish. In addition, it can also perform a water purification function.
[0009]
When the cue groove 5 in the horizontal direction is provided in the back plate portion 2, it becomes a clue to escape when a child or the like accidentally falls into the waterway.
In addition, the provision of the water-permeable slit 6 at the bottom can promote drainage of a sidewalk or the like downward.
[0010]
Further, the provision of the hole 7 for moving organisms in the partition wall 3 enables fish and other underwater organisms to move in and out of the block.
In addition, the provision of the through hole 8 in the bottom 1 can promote the propagation of aquatic plants from below the block.

【Example】
1 and 2 show an overhanging daylighting block of the present invention suitable for a case where the construction site is soft ground. FIG. 1 is a perspective view showing a construction state, and FIG. 2 is a side view. In this example, a bottom beam 11 is bridged over driving piles 10, 10 on both sides which are driven to withstand settlement unique to soft ground. A wall beam 12 that is inclined from the end of the bottom beam 11 at an angle (in this case, approximately 50 °) sufficient for daylighting is provided continuously. The back plate 2 and the partition wall 3 are held between the bottom beam 11 and the wall beam 12 provided at predetermined intervals in the flow direction of the water channel. The plate-shaped back plate 2 is supported by the support recess 12 a on the back side of the wall beam 12. If the back plate portion 2 is provided with a groove-shaped (or gap) cue groove 5 at an appropriate position, the back plate portion 2 serves as a clue when a child or the like who accidentally falls into a waterway escapes. The partition wall portion 3 is supported by a holding groove 11 a provided in the bottom beam 11.
[0012]
Since the partition wall portion 3 is provided with the hole 7 for moving organisms, fish and the like can survive fish nests and waterside plants in the lighting vegetation gap 4 between the rear plate portion 2 of the bottom portion 1 and the partition wall portion 3. enable. Between the back slab 2 and the partition 3, natural sunlight 13 or the like is thrown in without a bottom plate and in a hollow state, so that natural plants 13 and the like are provided, thereby giving vegetation and living space. An overhang 18 is formed above.
[0013]
FIGS. 3 and 4 also show an overhanging daylighting block of the present invention which is used when the construction site is on soft ground. FIG. 3 is a perspective view showing the construction state, and FIG. 4 is a side view. In this example, the partition wall portion 3 is fitted into the lower notch 14a of the upright column 14 provided from the bottom beam 11 to the upper portion until reaching the top of the wall beam 12, and is held down by natural stone 13 afterwards. Both the wall beam 12 and the standing beam 14 are in a state where the lower portion is divided, and the upper length can be freely changed and the height can be adjusted.
[0014]
FIG. 5 shows a back plate portion 2 forming an overhanging portion 18 at the back and a partition wall portion 3 lower than the back plate portion 2 at the front portion with respect to the bottom portion 1 provided with a through hole 8 appropriately. This is an integrated overhanging daylighting block. The bottom 1 has an area that forms a lighting vegetation gap 4 for fish nests and waterside plants between the back plate 2 and the partition 3. The back slab 2 has a vertical wall 2a at the bottom, an inclined wall 2b such that the upper part is forward at an angle at which light can be collected into the daylighting vegetation gap 4, and forms an uppermost top end 2c. The partition wall portion 3 is provided at a position substantially below the upper end of the rear plate portion 2 and just below the top end. The back plate 2 is provided with a water-permeable slit 6. The partition wall 3 is provided with a biological transfer hole 7. The plate-shaped back plate 2 is provided with a water-permeable slit 6.
[0015]
FIG. 6 shows a projection 1a, 1b provided at the front and rear with respect to the bottom 1 of the embodiment, and a cast-in-place reinforcing bar 1c projected at the front. This allows the bottom of the channel to be integrated with cast-in-place concrete. The back plate 2 is provided with a water-permeable slit 6.
[0016]
7 and 8 show examples of an overhanging daylighting block in which a water channel bottom is integrated. In this example, a through hole 15 is provided at the bottom of the water channel. The left and right have substantially the same structure as that shown in FIGS. The back plate 2 is provided with a water-permeable slit 6.
[0017]
FIG. 9 shows a type in which the partition wall portion 3 is formed separately and assembled. The structure in which the partition wall 3 is formed separately can be adopted in any of the cases shown in FIGS. An intermediate portion of the bottom portion 1 has a hollow structure with a through-hole 16.
[0018]
【The invention's effect】
Since light can be sufficiently taken into the overhanging waterway according to the present invention, it is possible to provide a living space for aquatic plants, aquatic animals, especially fish, and to form a multi-natural waterway. it can.
