[Industrial applications]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gutter block and a grating used in the gutter block, and particularly to a grating for guiding not only water on the ground (road surface) outside the gutter block but also water permeating into the ground into the gutter block. And a gutter block in which this is used.
[0002]
[Prior art]
Rainwater, etc., is guided into the gutter block buried on the side of the road, etc., through drainage grooves, etc. In addition, the bearing that constitutes this grating by replacing part of the gutter cover with grating In some cases, surface water is guided from a gap between the plate or the bearing bar into the drainage groove in the gutter block.
[0003]
By the way, in recent years, on the ground surface outside the gutter block, a frame stone, crushed glass, or the like, or those coated with resin are used, so that rainwater or the like is easily immersed in the ground, so-called water permeability. Sexual pavement 50 is being made. According to the water-permeable pavement 50, a gap having a three-dimensional network structure in which rainwater flows or accumulates is formed between crushed stones or the like, and rainwater infiltrates or accumulates in the ground through this gap. For this reason, according to this permeable pavement 50, it is difficult for puddles to be formed on the ground surface or on the road surface.
[0004]
However, even with such a permeable pavement 50, if heavy rain falls within a short time, or if rainwater does not quickly penetrate into the ground under the permeable pavement 50, the surface of the permeable pavement 50 is inevitable. A puddle will be formed in the area. If the puddle is formed on a road or sidewalk, people's feet may get wet or water may be splashed by cars.
[0005]
In addition, since the permeable pavement 50 forms a gap through which rainwater and the like pass through by crushed stones and the like, it is necessary to implement such that the gap is not crushed. Sufficient drainage must be provided in the drain gutter. In order to make the ground surface flat, it is necessary to make the upper surface of the side wall of the buried gutter coincide with the surface of the permeable pavement 50, but since there are many gaps in the permeable pavement 50. When the permeable pavement 50 is used for a long time, the gap may be crushed and the surface of the permeable pavement 50 may be lowered from the upper surface of the side wall of the gutter. In such a case, as shown also in FIG. 28, a dent 51 is formed in the water-permeable pavement 50 located immediately near the gutter block 20, and water may accumulate in the dent 51.
[0006]
In other words, in forming the water-permeable pavement 50, the following is required for the gutter block buried in the vicinity thereof.
[0007]
(1) Rain water or the like soaked in the permeable pavement 50 is immediately introduced into the gutter block so that water does not accumulate on the surface of the permeable pavement 50.
(2) In order to do the above, the grating for dropping the surface water into the gutter block was originally used, so this grating should be used.
(3) This grating can be used by making a slight change to the existing gutter block.
(4) Even if the surface of the permeable pavement 50 is lowered, the gutter block or grating should be able to drain the surface water.
[0008]
Therefore, the present inventors have conducted various studies on how to make a grating or a gutter block capable of satisfying the above requirements (1) to (4), and as a result, completed the present invention. It is.
[0009]
[Problems to be solved by the invention]
The present invention has been made on the basis of the above circumstances, and the problem to be solved is a grating capable of discharging rainwater in the permeable pavement 50, that is, groundwater, in a good manner, or to which this is applied. To provide a gutter block.
[0010]
In particular, an object of the present invention is to provide a grating 10 capable of discharging underground water in a good manner, and performing a simple construction work not only for a new gutter block but also for an existing gutter block. , And the gutter block 20 to which this is applied is provided by a simple configuration.
[0011]

It is.
[0012]
That is, according to this claim 1.Of grating for gutter block and gutter block in which it is used,As shown in FIG. 1, the grating 10 is formed by integrating a plurality of bearing plates or bearing bars 12 into the outer frame 11 with a gap therebetween. In addition to being guided into the inside, a water passage hole 12a is positively formed on at least one side surface thereof, so that water can be guided from the side of the side groove block 20 through the water passage hole 12a.
[0013]
The grating 10 is integrally formed on the upper part of the side groove block 20 instead of the groove cover 30 mounted on the mounting step part 20b formed inside the upper part of the side wall 20a of the side groove block 20, as shown in FIG. It is mounted on the mounting step portion 20b between the groove lid portions 31 and forms the same upper surface as the upper end surface of both side walls 20a. At least one side end (right end in FIG. 1) of the grating 10 is formed in the side wall 20a of the side groove block 20 so as to open upward as shown in FIGS. The grating 10 is stored and placed in the opening 21, whereby the grating 10 is supported on the side groove block 20.
[0014]
The water passage hole 12a of the grating 10 is generally formed on one side of the grating 10 as shown in FIG. 1 and the like. In this case, as shown in FIG. 4, it may be formed on both sides of the grating 10. As shown in FIG. 5, the side groove block 20 for mounting the grating 10 naturally has the insertion openings 21 formed in the both side walls 20a.
[0015]
The insertion slot 21 in which the end of the grating 10 is to be stored and placed may be formed in advance at the stage of manufacturing the gutter block 20, but the existing gutter block not having the insertion slot 21 may be formed. The insertion opening 21 may be formed at the site of the burial with respect to the insertion hole 20.
[0016]
In this case, if two cuts serving as the insertion openings 21 are inserted into the side wall 20a of the side groove block 20, and a knife is inserted into the cuts, the portion between the two cuts is easily broken. It can be formed into The height of the grating 10 can be easily adjusted by, for example, laying a mortar in the insertion opening 21.
[0017]
When the grating 10 configured as described above is placed on the gutter block 20, as shown in FIG. 2, rainwater or the like in the permeable pavement 50 formed on the side of the gutter block 20 can pass therethrough. Water can be guided from the water hole 12a to the drainage groove in the side gutter block 20, so that no water pool is formed on the permeable pavement 50.You.
[0018]
Therefore, according to the grating 10 of the present invention, the underground water 42 in the permeable pavement 50 can be drained into the gutter block 20 in a short time, so that no water pool is formed on the surface of the permeable pavement 50. And no problems due to puddles occur.
[0019]
Further, according to this claim 1.Grating for gutter block and gutter block for gutterThe side groove block 20NoteThe grating 10 is to be used, and at least one of the side walls 20a is formed with an insertion opening 21 into which the grating 10 is inserted from above. The side cover plate 22 having the hole 22a is integrated.
[0020]
That is, in the gutter block 20, for example, an insertion port 21 for guiding the underground water 42 in the permeable pavement 50 from the side of the gutter block 20 is formed. When the pavement 50 is constructed, the side cover plate 22 that prevents the material from spilling into the gutter block 20 and allows the underground water 42 to pass through the water passage hole 22a is integrated. The side groove block 20 can receive and place the grating 10 having the water passage hole 12a at the end by the insertion opening 21.,Thus, the rating 10 can be effectively used.
[0021]
The side cover plate 22 that blocks the insertion opening 21 of the side groove block 20 from the outside may be integrated with the outside of the insertion opening 21 using a concrete screw or an adhesive before the permeable pavement 50 is applied. However, it is advantageous to form the side groove block 20 integrally when it is formed. In this case, as shown in FIG. 3B, a mold bar 22b is welded to the back side of the side cover plate 22, and the mold bar 22b is attached as shown in FIG. It is preferable to mold the inside of the side wall 20a located around the insertion port 21.
[0022]
This claim1The side groove block 20 is a so-called U-shaped groove as shown in FIGS. 5 and 11 if it has the above-mentioned insertion opening 21 and side cover plate 22, and the groove cover 30 is placed on the mounting step portion 20b. , Or as shown in FIG. 9, FIG. 10, or FIG. 12, the groove cover 31 may be integrated with the side wall 20a to form an inverted U-shape. In addition, the groove cover 31 may be a side groove block 20 that is inclined as shown in FIG. 13. In this case, each of the insertion openings 21 or the grating 10 matches the inclination of the groove cover 31. What should I do?
[0023]
In addition, the side cover plate 22 that covers the outside of each insertion opening 21 is changed from a flat plate as shown in FIGS. 1 to 3 to a box-shaped plate as shown in FIG. be able to. Since the box-shaped side cover plate 22 of FIG. 14 can increase the number of side walls, it is possible to form a large number of water holes 22a for guiding the groundwater 42 in the permeable pavement 50. Can be advantageous.
[0024]
Of course, this claim1The side cover plate 22 used in the side gutter block 20 needs a water passage hole 22a for allowing the underground water 42 to flow from outside the gutter block 20, that is, from inside the permeable pavement 50. The water passage hole 22a may be a simple small hole as shown in FIG. 3B, or may be an alternative. That is, the water holes 22a are for guiding the underground water 42 into the gutter block 20 while preventing the material when the permeable pavement 50 is applied from spilling into the gutter block 20. For example, a net as shown in FIG. 19 (b) may be stretched over an opening formed in the side cover plate 22, or the opening may be closed with a thin bar.
[0025]
Therefore, the side groove block 20 according to the first embodiment can store and place the end of the grating 10 having the water passage hole 12a in the insertion opening 21, and the side cover provided outside the insertion opening 21. The underground water 42 in the permeable pavement 50 can be guided from the respective water holes 22a of the plate 22 to the water hole 12a side and drained into the gutter block 20, and the underground in the permeable pavement 50 can be drained. The drainage of the water 42 can be performed in a good manner, and a water puddle that causes various problems is not formed on the surface of the permeable pavement 50.
[0026]
Means taken by the invention according to claim 5 to solve the above problem is as follows:
“A plurality of bearing plates or bearing bars 12 are integrated into the outer frame 11 with a predetermined gap, and are mounted on the side groove block 20 instead of the groove cover 30 or a part of the groove cover 31. By doing, the grating 10 is configured to guide the surface water 41 from the respective gaps into the gutter block 20;
The length of the grating 10 can be placed in the insertion opening 21 formed so that at least one of the side walls 20a of the side groove block 20 is cut off,
In the side portion of the outer frame 11 on the insertion port 21 side,It is larger than the insertion opening 21 and comes into contact with the outer surface of the side wall on the side groove block 20 side.A grating 10 for a gutter block, characterized in that a side cover plate 14 is formed and a water passage hole 14a is formed in the side cover plate 14 to allow water to flow from the ground outside the gutter block 20 ".

[0027]
That is, this claim5As shown in FIG. 16 and the like, the grating 10 is provided with a side cover plate 14 integrally formed with a water passage hole 14a, a water passage elongated hole 14b, or the like at at least one end thereof. The underground water 42 outside the gutter block 20 is guided into the gutter block 20 via the side cover plate 14. In other words, this claim5The grating 10 according to the present invention eliminates the need to provide the side cover plate 22 in the insertion opening 21 on the side groove block 20 side, and has the inside of the insertion opening 21 formed in the existing side groove block 20 or the insertion opening 21. If it is stored as it is in the insertion opening 21 of the newly manufactured gutter block 20 as it is, the intended underground water 42 can be introduced into the gutter block 20.
[0028]
This claim5As shown in FIG. 16, the grating 10 is also housed in the insertion opening 21 formed in the buried gutter block 20 in advance or in the insertion opening 21 formed in a predetermined position on the side wall 20a of the existing gutter block 20. The side cover plate 14 covers the outer side surface of each insertion opening 21. When the grating 10 is applied to the gutter block 20 buried in a portion close to the curb block 60, the side cover plate 14 is provided with the structure shown in FIGS.18As shown in FIG. 22, only one is provided on the surface opposite to the curb block 60. For example, when the present invention is applied to the gutter block 20 buried in the central ridge of a road, FIG. 23, it is provided on both sides of the grating 10. As shown in FIG.
[0029]
As shown in FIGS. 20 and 21, the side cover plate 14 integrated with the grating 10 has a size enough to slip into the insertion opening 21 on the side groove block 20 side.However, the invention according to claim 5 isAs shown in FIGS. 18 and 19, the insertion portion 21 is larger than the insertion opening 21, and the enlarged portion is used as a contact portion 14d that comes into contact with the outer surface of the side wall 20a on the side groove block 20 side. I do. In the case of the side cover plate 14 having the contact portion 14d, by positioning the contact portion 14d against the outer surface of the side wall 20a, the positioning of the grating 10 with respect to the side groove block 20 can be easily performed. This is advantageous because the abutting portion 14d can prevent the material when the permeable pavement 50 is applied from spilling into the side groove block 20.
[0030]
Further, the side cover plate 14 has a water passage hole 14a for guiding the underground water 42 from outside the gutter block 20, and the water passage hole 14a is shown in FIG. It may be a simple hole as shown in a) or the like, or may be formed by a net 14c or a crosspiece as shown in FIG. This is the same as the case of the side cover plate 22 on the side. Moreover, this side cover plate 14IsNeedless to say, the hole may be a water passage slot.
[0031]
Claims configured as above5When the side cover plate 14 provided on at least one of them is placed and stored on the gutter block 20 so as to become the permeable pavement 50 to be implemented, as shown in FIG. The insertion opening 21 on the side groove block 20 side is completely covered by the side cover plate 14. Thereafter, the permeable pavement 50 is applied, and if the groove lids 30 are fitted on both sides of the grating 10, a state as shown in FIG. 17 is obtained. As a result, the underground water 42 in the permeable pavement 50 passes through the water hole 14a, the long water hole 14b, or the net 14c of the side cover plate 14 to form Water is introduced into the drain.
[0032]
Therefore, the grating 10 according to claim 5 requires only the processing of the insertion opening 21 with respect to the side groove block 20, and the execution can be easily performed only by the work of storing in the insertion opening 21, Then, the underground water 42, which was initially a problem, can be reliably introduced into the gutter block 20.
[0033]
The gutter block 20 used at this time is, ExhaustThe formation of the groove cover 30 or the mounting of the groove cover and the grating 10 on the upper portions of both side walls 20a constituting the water groove makes it possible to form the same surface as the road surface or the sidewalk surface and to mainly remove the surface water from the grating 10. 41 is a gutter block 20 for guiding water into a drain ditch,
An insertion port 21 on which the side end of the grating 10 is to be placed is formed on at least one of the side walls 20a,
Water can be introduced from the underground outside the gutter block 20 to the inside from the water passage 14a of the side cover plate 14 provided on the grating 10 placed and stored in the insertion opening 21. The gutter block 20 is characterized in that:
[0034]
That is,Side ofThe groove block 20 is shown in FIG.8aAlternatively, as shown in FIG. 22, unlike the side groove block 20 according to the first aspect, the side opening plate 21 does not have the side cover plate 22.
[0035]
Therefore, this gutter block 20 is suitable for applying the grating 10 according to claim 5, and can surely conduct water into the underground water 42 in the permeable pavement 50, and It prevents rainwater from accumulating on it.
[0036]
By the way, in order to solve the above-mentioned problem, claim 2Or claim 6Means taken by the invention according to the above claim is1 or Claim 5About grating 10 of

On the other hand, the side groove block 20 in which the grating 10 configured as described above is used has an insertion opening 21 formed in a part of the side wall 20a as shown in FIG. The outer surface is covered by the side cover plate 22.
[0052]
The insertion opening 21 is generally formed when the side gutter block 20 is formed of concrete, but for the existing gutter block 20,ConstructionIt can be easily formed by using a diamond cutter in place.
[0053]
The side cover plate 22 for covering the insertion opening 21 prevents a material such as crushed stone from falling into the gutter block 20 when the permeable pavement 50 or the like is implemented, and also sets a ground from the permeable pavement 50 side. Since it is possible to guide the intermediate water 42 into the gutter block 20, it is easiest to make it as shown in FIG. 3. That is, as shown in FIG. 3B, a large number of water passage holes 22a are drilled in a portion corresponding to the insertion opening 21 of the side cover plate 22 by a drill or the like. The mold bar 22b is integrated on the side by means such as welding. As shown in FIG. 3A, if the mold bar 22b is molded when the side groove block 20 is formed of concrete, the side cover plate 22 can be easily and reliably attached to the side wall 20a.
[0054]
Further, as shown by a virtual line in FIG. 3B, an upper notch 24 may be formed at the upper end edge of the side cover plate 22. These gutter blocks 20 allow rainwater in the recesses 51 shown in FIG. 28 formed when the water-permeable pavement 50 and the like outside the gutter block 20 to flow down to flow into the gutter block 20. Further, each water passage hole 22a formed in the side cover plate 22 can be formed as a long water passage hole 14b or formed by a net 14c as in a side cover plate 14 on the grating 10 side described later. .
[0055]
Further, in the grating 10 shown in FIG. 1, the water passage holes 12a are formed only on the right end face in the figure, but the water passage holes 12a are formed on both sides of the grating 10 as shown in FIG. It may be implemented. In such a case, the side groove block 20 on which the grating 10 is to be mounted has an insertion opening 21 and a side cover plate 22 formed on both side walls 20a as shown in FIG.
[0056]
In the grating 10 shown in FIGS. 3 and 4, the necessary height is secured by the outer frame 11 and the inner bearing plate 12, but the required height is secured by using the mounting table 16. This is shown in FIGS. 6 and 7. In these gratings 10, as shown in FIG. 8, the mounting table 16 to be mounted on the mounting step 20 b on the side groove block 20 is integrated with the outer frame 11 and the lower surface of the bearing plate 12. The holding table 15 is welded to the mounting table 16. The grating 10 shown in FIGS. 6 and 7 is different from that shown in FIG. 8 in the length of each outer frame 11 and the bearing plate 12. This indicates that the adjustment should be made in accordance with the position 20b.
[0057]
By the way, the side groove block 20 according to the present invention is not intended only for the one using only the groove cover 30 as shown in FIG. 1, but as shown in FIG. In this case, the grooved cover 30 has a space near the portion where the grating 10 is mounted, and has a space for the groove cover 30 to be placed. Of the side groove block 20 having the mounting step portion 20b. Regarding such a side groove block 20, one having an insertion opening 21 and a side cover plate 22 only on one side wall 20a as shown in FIG. 9 is inserted into both side walls 20a as shown in FIG. Those having the mouth 21 and the side cover plate 22 are also added as targets. Of course, as shown in FIG. 11, the side groove block 20 which has the insertion port 21 and the side cover plate 22 on both side walls 20a and is covered with only the groove cover 30 is also an object.

FIG. 12 shows a side groove block 20 having a groove cover 31 integrated with the side wall 20a. The point that this side groove block 20 differs from that described so far is that the inside of the side wall 20a is different. That is, a portion immediately below the insertion opening 21 has a shooter surface 23. Although the side groove block 20 of FIG. 13 also has such a shooter surface 23, the difference is that the groove cover 31 is inclined toward the front side in the figure.
[0059]
Now, the side cover plate 22 covering the insertion opening 21 of the side groove block 20 described above has been exemplified to be all flat, but the side cover plate 22 may be embodied in another shape. One example is shown in FIG. 14 and FIG. The side cover plate 22 shown in these figures is formed in a so-called box shape, and is designed to wrap the end on the grating 10 side. By doing so, the area of the side surface can be increased within the range of the thickness of the permeable pavement 50, and more water holes 22a can be formed. By 22a, the underground water 42 in the permeable pavement 50 can be more reliably guided into the gutter block 20.

[0064]
MaThe side cover plate 14 may be implemented not only at one end of the grating 10 but also at both ends as shown in FIG. In this case, as shown in FIG. 23, it is needless to say that the underground water 42 in the permeable pavement 50 on both sides can be guided in the gutter block 20.
[0065]
Now, the grating 10 having the side cover plate 14 isShown as a reference exampleAs shown in FIG. 24, each of the outer frame 11 and the bearing plate 12 may be configured to be narrower in the vertical direction. In this case, instead of the bearing plate 12, a bearing bar is used. is there. If such a grating 10 is not high enough to be mounted on the mounting step 20b on the side groove block 20, the mounting table 16 as shown in FIGS. It is sufficient to integrate them or to integrate the holding portions 18 as shown in FIGS. 26 and 27.
[0066]
As shown in FIGS. 6 to 8, for the mounting table 16 and the lifting section 18, the holding table 15 is further provided as shown in FIGS. As shown in FIG. 26 and FIG. 27, the lower end portion of the lifting portion 18 may be used as the presser table 15.
