Description

  The present invention relates to a water channel forming block 100 comprising a side groove and a side groove cover for covering the upper end opening thereof, and in particular, the water channel forming block having a permeation hole for allowing the side groove cover to flow rainwater into the side groove. 100.

  In recent years, most of the “side grooves” installed on the side of the road are covered with “side groove covers”. The most important reason is to increase the safety of the gutter, but by covering it, rainwater that has flown freely until then becomes difficult to flow. In some cases, rainwater that has not flowed in accumulates on the road side, and rainwater splashed by the traffic of a car is applied to a person walking on the sidewalk.

  For this reason, measures are taken to replace a part of the side groove lids arranged in large numbers with “grating” formed by combining metal “crosspieces”. However, this grating is inconvenient because the heel part of the high heel fits in or the tip of the claw is caught. There is still a high demand for it.

  Therefore, it was considered that a permeation hole was positively formed in the side groove lid itself, and rainwater was poured into the side groove groove from this permeation hole, but if the permeation hole was formed, the strength would be weakened. Naturally.

  In order to solve the above points, for example, Patent Document 1 proposes a “groove cover”. As shown in FIG. 13, the groove cover of this Patent Document 1 is “a groove cover used for a side groove of a conventional road or the like has a drain hole that leads to the groove at a required location. The present invention was made for the purpose of providing a drain hole and sufficiently draining water without reducing the strength of the groove lid. "A copper plate drainage fitting Ga1 having a concavo-convex shape is embedded in the central portion in the direction perpendicular to the groove direction of the groove lid a1, a hole 3 is bored, and the concave surface of the drainage fitting G1 is aligned with the position of the opening 13, The punch hole G13 is bored, and the opening 13 has a configuration of “groove lid that is bored avoiding the reinforcing bar of the groove lid a1”.

  Also in Patent Document 2, as shown in FIG. 14, “a side groove lid that efficiently guides rainwater into the side groove and has a small strength decrease with respect to a load load, a mold for manufacturing the side groove cover, and a side groove cover thereof. For the purpose of “providing a method for manufacturing the groove”, “a groove portion that traverses in the width direction is provided on the upper surface of the main body, and one or both ends of the groove portion are side opening portions that open to the side surface of the main body. There has been proposed a “side groove lid” having a configuration called “a side groove lid in which a communication hole communicating with the inside of the side groove is formed at the bottom”, and the side groove lid is configured such that “rain water passes through the communication hole from the groove portion of the side groove lid. Since it is led into the side groove, it has a function of promoting the inflow of rainwater.

And also in patent document 3, as shown in FIG. 15, for the purpose of "providing the collection and drainage capacity at the time of rainfall and a landscape, or the side groove cover plate aiming at reduction of rattling noise by vehicle running" “The shape of the upper surface of the side groove cover plate is a dish shape, a substantially V shape, a single inclined shape, a top opening 22 type shape, or a flat shape, and 1 to several inverted Vs in the vertical or horizontal direction at the center of the cover plate. A configuration in which a slit hole having a funnel shape is provided, or a shallow water collecting groove communicating with the slit hole is disposed, and a convex portion for adjusting the position in the lateral direction or the length direction is formed on the side surface of the lid. "Side gutter lid plate" having the above has been proposed.
JP 2001-164640 A, Summary Japanese Patent Laid-Open No. 11-148168, abstract Japanese Patent Laid-Open No. 2002-23536, Abstract

  However, the groove lid described in Patent Document 1 has a complicated structure as shown in FIG. 13 and also does not solve the problems of high heels and grips. Of course, in the side groove cover of Patent Document 2 shown in FIG. 14, since the grating is provided on the upper surface side, the problem of high heels and the grip is not solved as in the case of the groove cover of Patent Document 1.

  On the other hand, since the side groove cover plate described in Patent Document 3 has a simple shape as shown in FIG. 15, it is considered that the high heel and the foot are hardly caught. , “The top shape is a dish shape, a substantially V shape, or a single inclined shape”, etc., and a “longitudinal or lateral slit hole is provided in the center of the lid”. It is thought that it is easy to break as.

  That is, in the “side groove lid slope” described in Patent Document 3, as shown in FIG. 15, a “slit hole” that is about half the length is formed in the center in the longitudinal direction. Therefore, it is considered that there is a high possibility of cracking starting from the slit hole when the wheel of a car gets on. Moreover, since this slit hole is opened in a state of being lowered at the center, it is considered that there is a very high possibility that fallen leaves and dust will flow in along with the inflow of rainwater, and the folded hole will be blocked.

  Moreover, generally speaking, the gutter itself is constructed so as to cause a drop in the longitudinal direction in order to flow water, but it is not necessary to consider the drop in the width direction. Therefore, it is not considered much. In other words, when looking at the side groove cover, the horizontal direction in FIG. 2 is not necessarily in a completely horizontal state, and is often inclined in either direction. This has a subtle effect on the flow of rainwater.

  Further, when considering the side groove itself in which the above-mentioned side groove cover is accommodated, the upper end surface thereof (the upper surface on both sides of the portion into which the side groove cover is fitted) forms substantially the same surface as the upper surface of the side groove cover. In addition, the outside of the side groove, for example, the upper surface of the road and the upper surface of the side groove cover are also partitioned. In other words, both upper end surfaces of a general conventional side groove prevent inflow of rainwater from the road to the side groove cover side, and the general side groove instead guides rainwater on the road into the side groove. It was not.

  Therefore, the inventor of this type of water channel forming block 100 composed of a side groove and a side groove cover does not impair the strength of the side groove cover, of course, rainwater or the like swung on the side groove cover, and on the outside of the side groove. The present invention has been completed as a result of various studies on how to sufficiently introduce a certain rainwater into the lateral groove.

  That is, the purpose of the present invention is to maintain the strength of the side groove lid by reducing the permeation hole for inflow of rainwater into the side groove as much as possible, and inflow of rainwater into the side groove. As for the side groove, it is possible to guide the rainwater on the outside to the permeation hole of the side groove cover, and as a result, a water channel that can sufficiently discharge the rainwater is formed. The object block 100 is provided with a simple configuration.

In order to solve the above problems, first, the means taken by the invention according to claim 1 will be described with reference numerals used in the description of the best mode described below.
“Water channel construction block 100 comprising a side groove 20 and a side groove cover 10 which is housed in the upper end opening 22 of the side groove 20 and forms the same cover with respect to the upper end surface 21 of the side groove 20 and the cover of the upper end opening 22. Because
A permeation hole 12 is formed in the side groove lid 10 so as to pass through the vertical direction of the rainwater, and a first guide groove 13 that communicates with the permeation hole 12 and guides the inflow of rainwater is formed on the upper surface 11 of the side groove lid 10. In addition, the bottom surface 13a of the first guide groove 13 is inclined toward the transmission hole 12, and
A waterway construction block 100 characterized in that a second guide groove 23 that is continuous with the first guide groove 13 formed on the side groove lid 10 side is formed on at least one of both upper end surfaces 21 of the side groove 20.
It is.

  That is, as shown in FIGS. 1 and 2, the water channel forming block 100 includes a side groove lid 10 having a perforation hole 12 and a first guide groove 13 communicating with the perforation hole 12, and the side groove lid 10 having an upper end. It is housed in the opening 22 and is composed of the side groove 20 in which the second guide groove 23 is formed on the upper end surface 21, and constitutes a water channel such as a drainage channel by arranging a predetermined number thereof. .

  As shown in FIGS. 3 and 6 to 8, the side groove lid 10 has a plurality of transmission holes 12 formed in the vertical direction of the main body portion, and has poured onto the upper surface 11 through each of the transmission holes 12, or The rainwater that has flowed is poured into the lower side groove 20.

  If each permeation hole 12 is enlarged, the inflow of rainwater into the side groove 20 can be promoted, but considering the strength of the entire side groove cover 10, it cannot be made so large. Therefore, the first guide groove 13 connected to each permeation hole 12 is formed on the upper surface 11, and the inflow of rainwater into each permeation hole 12 is made effective by the first guide groove 13.

  In other words, each of the first guide grooves 13 can make the size of each transmission hole 12 so as not to weaken the strength of the side groove lid 10 itself, and can not be captured only by the upper end hole of each transmission hole 12. It is also compensated so that it can catch rainwater. In other words, each first guide groove 13 is formed directly on the upper side opening 11 or on the other upper surface 11 or on the road to catch rainwater that has flown from the upper end opening as a whole, and is formed in the entire side groove lid 10. The trapped rain water is poured into the permeation holes 12 by the bottom surface 13a. Of course, the first guide groove 13 does not penetrate the side groove lid 10 itself, and therefore does not reduce the strength of the side groove lid 10.

  In the side groove lid 10, the bottom surface 13 a of each first guide groove 13 is inclined toward the transmission hole 12. If the bottom surface 13a is not inclined but is parallel to the top surface 11 of the side groove cover 10, the rainwater that has flowed into the first guide groove 13 is caused by, for example, pebbles or dust clogged in the first guide groove 13 Although it becomes difficult to flow, since each bottom face 13a is inclined toward the permeation hole 12, the flow of rainwater to the permeation hole 12 is always performed in a stable state. This is because small stones and dust are poured into the transmission hole 12 by the bottom surface 13a.

  Further, since each bottom surface 13a is inclined, even if the side groove cover 10 is not supported in a horizontal state and tends to be left or right in FIG. Pouring is surely done. If the side groove cover 10 is tilted in the left-right direction in FIG. 2, if the construction and shape of the side groove 20 itself is out of specification, the re-execution is performed, and the side groove 20 and the side groove cover 10 If pebbles etc. incline in between and tilt, it is not so big. In any case, the inclination of the side groove lid 10 in the left-right direction in FIG. 2 is within the inclination range of the bottom surface 13 a of each first guide groove 13, and the bottom surface 13 a directs rainwater or the like toward the transmission hole 12. It will be enough to pour.

  As a result, the side groove lid 10 can maintain the strength by making the permeation hole 12 for flowing in the rainwater into the side groove 20 as small as possible, and can effectively flow in the rainwater into the side groove 20. Since the bottom surface 13a of the first guide groove 13 is inclined toward the permeation hole 12, the rainwater permeation to the permeation hole 12 can always be performed stably.

  Now, although it is the side groove 20 which comprises the block 100 for water channel formation concerning this Claim 1, the schematic shape of this side groove 20 and the general thing which formed the upper end opening 22 between both upper end surfaces 21, and that It is substantially the same. However, looking at the details of the side groove 20, as shown in FIGS. 9 and 10, a plurality of second guide grooves 23 are formed on at least one upper end surface 21 thereof.

  As shown in FIG. 1, each upper end surface 21 is positioned corresponding to the first guide groove 13 on the side groove cover 10 side when the side groove cover 10 is stored in the upper end opening 22 of the side groove 20. As shown in FIG. 11B, the upper surface of the road and the inside of the side groove 20 are communicated with each other through the first guide groove 13 on the side groove cover 10 side.

  In order to be like this, the second guide groove 23 and the first guide groove 13 on the side groove lid 10 side always correspond, that is, must face each other at the same position. In this case, normally, the four side groove lids 10 are formed so as to be completely accommodated in one side groove 20, and the four side groove lids 10 are made the same size, so that no problem occurs. That is, if the four side groove lids 10 are completely accommodated in one side groove 20, even if they are formed separately, the first guide groove 13 on the side groove lid 10 side and the second guide groove 23 on the side groove 20 side. Is completely opposite.

  Therefore, according to the water channel forming block 100 according to the first aspect, the side groove lid 10 can maintain the strength by making the permeation hole 12 for inflow of rainwater into the side groove as small as possible, Moreover, inflow of rainwater into the side groove 20 can be performed effectively, and the side groove 20 can be guided to the permeation hole 12 of the side groove lid 10 with respect to the outside rainwater, and as a result. The rainwater can be discharged sufficiently.

In order to solve the above-mentioned problem, the means taken by the invention according to claim 2 is as follows.
“In the side groove lid 10, the transmission holes 12 and the first guide grooves 13 communicating with the transmission holes 12 are formed on opposite sides of the side groove lid 10, respectively.
The second guide groove 23 corresponding to each first guide groove 13 is formed on the upper end surface 21 of the side groove 20 "
It is.

  That is, in the waterway constituting block 100 according to this second aspect, the side groove lid 10 has a pair of the transmission hole 12 and the first guide groove 13 communicating therewith as shown by the phantom line in FIG. The side groove cover 10 is formed not only on the lower side of the figure but also on the upper side of the figure.

  In this way, when the waterway construction block 100 is arranged between the sidewalk and the road, it is possible to drain the rainwater flowing from both at the same time. The bottom surface 13a of the first guide groove 13 on the upper side is more inclined toward the transmission hole 12 regardless of whether it is inclined to the left or right, and the rainwater is introduced into the side groove 20. It is made more effective.

  Of course, the second guide groove 23 on the side groove 20 side may be formed at a position facing each first guide groove 13 indicated by a virtual line in FIG.

  Therefore, the water channel forming block 100 according to claim 2 exhibits the same function as that of claim 1, and when it is disposed between the sidewalk and the road, it drains rainwater flowing from both. As a matter of course, either of the first guide groove 13 and the second guide groove 23 can have bottom surfaces 13a and 23a that are largely inclined, so that the rainwater can be guided into the side groove 20. It can be done more reliably.

In order to solve the above-mentioned problem, the means taken by the invention according to claim 3 is the gutter lid 10 according to claim 1 or 2,
“The bottom surface 23a of the second guide groove 23 is inclined toward the side groove 20”.
It is.

  That is, in this water channel forming block 100, as shown in FIG. 11 (b), the bottom surface 23a of each second guide groove 23 is the same as the bottom surface 13a of each first guide groove 13 on the side groove lid 10 side. The second guide groove 23 is inclined toward the side groove 20 formed therein. In the best mode, as shown in FIG. 12B, the second guide groove 23 has a wide entrance side so that dust or the like does not flow into the first guide groove 13 side.

  If the bottom surface 23a of the second guide groove 23 is not inclined but parallel to the upper end surface 21 of the side groove 20, the rainwater flowing into the second guide groove 23 becomes difficult to flow. Since it is made to incline toward the side groove 20, the rainwater is always poured into the first guide groove 13 in a stable state.

  Moreover, since each bottom surface 23a is inclined, even if this side groove lid 10 is not supported in a horizontal state and tends to be left or right in FIG. Pouring is done reliably. If the side groove cover 10 is tilted in the left-right direction in FIG. 2, if the construction and shape of the side groove 20 itself is out of specification, the re-execution is performed, and the side groove 20 and the side groove cover 10 If pebbles etc. incline in between and tilt, it is not so big. In any case, the inclination of the side groove cover 10 in the left-right direction in FIG. 2 is within the inclination range of the bottom surface 23 a of each second guide groove 23, and the bottom surface 23 a directs rainwater or the like into the side groove 20. It will be enough to pour.

  Therefore, the water channel forming block 100 according to the third aspect of the present invention exhibits the same function as that of the first or second aspect of the present invention, and can more reliably guide the rainwater into the side groove 20.

As detailed above, in the present invention,
“In the water channel construction block 100, which is housed in the side groove 20 and the side groove cover 10 which is housed in the upper end opening 22 of the side groove 20 and forms the same surface with respect to the cover of the upper end opening 22 and the upper end surface of the side groove 20. There,
A permeation hole 12 is formed in the side groove lid 10 so as to pass through the vertical direction of the rainwater, and a first guide groove 13 that communicates with the permeation hole 12 and guides the inflow of rainwater is formed on the upper surface 11 of the side groove lid 10. In addition, the bottom surface 13a of the first guide groove 13 is inclined toward the transmission hole 12, and
The second guide groove 23 that is continuous with the first guide groove 13 formed on the side groove lid 10 side is formed on at least one of the upper end surfaces 21 of the side groove 20 ".
Therefore, the side groove lid 10 can maintain the strength by making the permeation hole 12 for flowing in the rain water into the side groove as small as possible, and also into the rain water side groove 20. Inflow of rainwater can be effectively performed, and the rainwater outside the side groove 20 can be guided to the permeation hole 12 of the side groove lid 10, and as a result, the rainwater is sufficiently discharged. The water channel forming block 100 that can be provided can be provided with a simple configuration.

  Next, the water channel forming block 100 which is the best mode shown in the drawings of the invention according to each claim configured as described above will be described.

  As shown in FIGS. 1 and 2, the water channel forming block 100 according to the best mode includes a side groove lid 10 having a perforation hole 12 and a first guide groove 13 communicating with the perforation hole 12, and an upper end surface 21. And a side groove 20 having a second guide groove 23 formed thereon, and a water channel such as a drainage channel is formed by arranging a predetermined number thereof. Of course, a plurality of (four) side groove lids 10 are accommodated in the side groove lid 10 of the side groove 20 as shown in FIG. 1, but each side groove lid 10 is as shown in FIG. In addition, the cover of the upper end opening 22 of the side groove 20 and the same surface with respect to the upper end surface 21 of the side groove 20 are formed.

  3 to 7, a plan view, a bottom view, a right side view, a longitudinal sectional view in the longitudinal direction, and a longitudinal section in the longitudinal direction of the side groove cover 10 constituting the water channel forming block 100 according to the present invention are shown. Each of the side groove covers 10 is reinforced with a reinforcing bar 14 and integrally molded with concrete. In addition, the side groove cover 10 may be formed with a handle 15 as shown in FIG. 4. In addition to introducing the handle 15 into the side groove 20 side through the handle 15, the side groove cover 10 is also provided. The handle 15 is also used when lifting from the ten side grooves 20.

  Now, each side groove lid 10 has a plurality of (four in the example shown in FIG. 1 on the lower right side) transmission holes as shown in FIGS. 12 is formed. Each permeation hole 12 is for introducing rainwater that flows down or flows onto the upper surface 11 of the side groove lid 10 into the lower side groove 20, and the lower side is large as shown in FIGS. 4 and 6. It is the through-hole of the up-down direction made to become. This is because the water passing function of each permeation hole 12 is always improved by preventing pebbles and dust that have entered the permeation hole 12 from stopping midway.

  As shown in FIGS. 1, 7, and 8, a first guide groove having an actual depth (less than about 1/10 of the thickness of the side groove cover 10) is formed on the upper surface 11 at the upper end of each transmission hole 12. 13 are in communication with each other, and one end of the first guide groove 13 is open on the end face of the side groove cover 10. Since the first guide groove 13 is not so deep as shown in FIG. 7, the heel portion of the high heel and the tip of the shoe are not caught by this.

  Further, as shown in FIGS. 7 and 8, the bottom surface 13a of the first guide groove 13 is inclined toward the transmission hole 12, and rainwater sufficiently flows into the transmission hole 12 by the inclined surface. It is a thing.

  In addition, although each 1st guide groove 13 shown as the continuous line of FIG. 1 was opened in alignment with the one side end surface of the side groove cover 10, as shown with the virtual line in FIG. You may implement so that the 1st guide groove 13 may open in the edge | side on the opposite side to others. In this case, since the bottom surface 13a of each first guide groove 13 is inclined to the opposite side, the installation groove of the side groove cover 10 is not affected so much, that is, the side groove cover 10 is shown in FIG. Even if it is inclined in any of the left and right directions, not only can water flow into the side groove 20 of rainwater, but also when the waterway constituting block 100 is arranged between the sidewalk and the road, it flows from both of them. The rainwater coming can be drained at the same time.

  Needless to say, the side groove lid 10 is housed in the upper end opening 22 (see FIG. 3) formed in the side groove 20 and covers the upper end opening 22 as in a general case.

  Now, the side groove 20 constituting the water channel forming block 100 has a schematic shape in which an upper end opening 22 is formed between both upper end surfaces 21 as shown in FIGS. 1 and 2. It is almost the same as the general one. However, when the details of the side groove 20 are viewed, as shown in FIGS. 9 and 10, a plurality of second guide grooves 23 are formed on at least one upper end surface 21.

  As shown in FIG. 1, each upper end surface 21 is positioned corresponding to the first guide groove 13 on the side groove lid 10 side when the side groove lid 10 is accommodated in the upper end opening 22 of the side groove 20. As shown in FIG. 11B, the road upper surface and the inside of the side groove 20 are communicated with each other through the first guide groove 13 on the side groove cover 10 side.

  In order for each second guide groove 23 to communicate with the first guide groove 13 on the side groove cover 10 side, the second guide groove 23 and the first guide groove 13 on the side groove cover 10 side always correspond, that is, the same position. However, since the four side groove lids 10 are formed so as to be completely accommodated in one side groove 20, and have the same size, no problem occurs. That is, if the four side groove lids 10 are completely accommodated in one side groove 20, even if they are formed separately, the first guide groove 13 on the side groove lid 10 side and the second guide groove 23 on the side groove 20 side. Is completely opposite.
