Description

  The present invention relates to a structure of a drain groove that is long and continuous in a belt-like shape provided on a side of a road, a sidewalk, a park, a parking lot, or the like. In particular, the present invention relates to a structure of a receiving frame and a groove lid for a side groove or a catchment that enables maintenance.

  The upper part of the U-shaped drainage groove has a large opening. In order to increase the width of the roadway or to prevent the intrusion of dust into the drainage groove and to maintain the scenery of the road, the drainage groove structure is such that the width of the groove lid is narrower than the upper opening width of the drainage groove. It has been proposed (for example, Patent Document 1).

  In addition, in recent years, the groove cover has not only been able to drain, but the design of the surrounding pavement and design has been unified, and the groove cover is not conspicuous when laying, and has been devised to maintain the beauty of the pavement space. Groove lids are also widely used. For example, it is a groove lid having a structure having a filling portion capable of filling a pavement material such as a tile having the same design as the periphery of the groove lid and a drainage portion including a slit (for example, Patent Document 2).

JP 2004-346701 A JP 11-131577 A

When the side groove is long and continuous, it is necessary to install a maintenance groove cover for removing dust, gravel, etc. accumulated in the groove at intervals of about 5 m or 10 m. In addition, it is necessary to be able to perform maintenance on the lid for collecting water.
And in order to perform maintenance, it is necessary to remove all the groove covers of the filling part and the drainage part and to open them largely. Thus, if it is made the structure which can remove all the groove covers of a filling part and a drainage part, when these groove covers are installed in a receiving frame, there exists a problem that it is easy to produce rattling. In particular, considering the passage of heavy objects such as trucks, a solid structure that does not loosen over time is required.

The configuration described below can be basically applied to a dredger for collecting water, and the effects of the invention described below also occur in the dredger for collecting water.

Embodiment 1 FIG.
The groove covering structure according to the first embodiment of the present invention mainly includes a receiving frame 1, a decorative groove lid 2, and a grating 3. Below, each structure is demonstrated.
First, the structure of the receiving frame 1 is demonstrated using FIG. The receiving frame 1 is composed of left and right side plates 11L and 11R and two beams 12 arranged at front and rear ends (upper and lower ends in FIG. 1) for connecting them. The left and right side plates 11L, 11R and the two beams 12 are firmly joined by welding or the like.

The left and right side plates 11 </ b> L and 11 </ b> R are bent at a right angle in a direction in which the left and right side plates 11 </ b> L face each other, and constitute a part of the bottom surface of the receiving frame 1. An opening 15 is formed in the central portion of the bottom surface of the receiving frame 1 as an intermediate portion for allowing drainage such as rainwater to flow into a drainage groove body such as a U-shaped groove.
A plurality of intermediate beams 13 are provided at the same height as the beams 12 between the two beams 12.
A plurality of supports 14 are provided on the left side plate 11L. The height at which the support 14 is provided is provided above the intermediate beam 13 (on the front side in FIG. 1). In FIG. 1, each support body 14 is provided in the vicinity immediately above each intermediate beam 13, but the positions of the intermediate beam 13 and the support body 14 may be shifted back and forth.

  As for the configuration of the support 14, an enlarged view is shown in FIG. The support body 14 includes a base wall 141 fixed to the left side plate 11L by welding or the like, a first support plate 142 extending from the upper edge of the base wall 141, and a first support plate 143 extending from the lower edge of the base wall 141. Thus, a U-shaped structure is formed, and the back side of the U-shaped structure is closed by the reinforcing wall 144. A support wall 145 is formed upward from the first support plate 142. The support 14 is formed by pressing, cutting of a metal square, or the like.

Next, the configuration of the decorative groove cover 2 will be described with reference to FIG.
The decorative groove lid 2 includes a filling frame body 21 that is a box-like body having an upper opening, a filling member 22 such as tiles and mortar filled in the filling frame body 21, and the filling frame body 21. It comprises a plurality of supports 23 provided on the left side surface. The shape of the support 23 is congruent with the support 14 and symmetrical. Each of the plurality of supports 23 is provided at a position facing each of the plurality of supports 14.

A state in which the decorative groove cover 2 is installed on the receiving frame 1 is shown in FIGS. 3 is a view from above, and FIG. 4 is a cross-sectional view taken along the line AA in FIG.
As shown in FIG. 4, the receiving frame 1 is placed on the drainage groove 4. The shape below the left and right side plates 11L and 11R of the receiving frame 1 may be adapted to the shape of the upper part of the drainage groove 4. Therefore, the shape below the left and right side plates 11L and 11R shown in FIG. 4 is an example.

Anchors and bolts inserted therein are appropriately provided below the left and right side plates 11L and 11R, and the receiving frame 1 and the drainage grooves 4 are joined by tightening the bolts. Further, when concrete is placed around, the receiving frame 1 and the concrete are strongly joined by the anchor. In FIGS. 1 and 3 which are top views, the anchors and bolts are not shown.
Thus, after the receiving frame 1 is placed on the drainage groove 4, the decorative groove lid 2 is installed on the receiving frame 1.

  The decorative groove cover 2 is placed on the two beams 12 and the plurality of intermediate beams 13 of the receiving frame 1. In the state where the decorative groove lid 2 is placed, each of the plurality of supports 14 provided on the receiving frame 1 and the plurality of supports 23 provided on the cosmetic groove lid 2 has the same height, It comes to face at the same front and back position.

Next, the configuration of the grating 3 will be described with reference to FIG.
The grating 3 includes two side bars 31 installed at the left and right ends, a plurality of bearing bars 32 provided between the two side bars 31, two end bars 33 installed at the front and rear ends, and a plurality of crosses. A bar 34 forms a framework. Further, a fastening portion 35 is provided near the front and rear ends. The number of fastening portions 35 attached to the grating 3 is two in this example, but may be increased to three or more if it is necessary to realize a stronger structure. On the other hand, when the total length is short, a single fastening portion 35 may be sufficient. An enlarged view of the fastening portion 35 is shown in FIG.

The fastening base 351 of the fastening portion 35 is provided in a space formed by cutting some bearing bars 32 in the middle, and is joined to the end portions of the cut bearing bars 32 by welding or the like. Or you may join with the bearing bar 32 arrange | positioned at the both sides of the fastening base 351. FIG.
An opening into which the bolt 352 can be inserted is opened near the center of the fastening base 351. A bolt 352 is inserted into the opening from above.

The fastening plate 353 is a rectangular plate having a width slightly smaller than the width of the grating 3, and has an opening at the center thereof, and a nut 354 is provided directly below the opening.
Below the fastening base 351, the bolt 352 is lightly screwed into the nut 354. This state is the state of the enlarged view shown in FIG.

Next, a procedure for attaching the grating 3 to the configuration in which the decorative groove cover 2 is installed on the receiving frame 1 shown in FIGS. 3 and 4 will be described with reference to FIGS.
First, as shown in FIG. 6, the grating 3 is placed in the receiving frame 1 at a position shifted slightly forward (downward in FIG. 6) so that the fastening plate 353 does not hit the supports 14 and 23. At this time, the support walls 145 of the supports 14 and 23 serve as a positioning reference for determining the left and right positions of the grating 3. Also, it has a role of preventing the grating 3 from falling into the groove when being attached or detached.

  And it pushes in the direction of the white arrow of FIG. When pushing in, the height of the grating 3 is adjusted so that the fastening plate 353 enters the U-shaped opening of the cross section of the supports 14 and 23. Then, the grating 3 is pushed in until it hits the reinforcing wall 144 of the supports 14 and 23. FIG. 7 shows a cross section taken along the line AA in the fully pushed state. The fastening plate 353 is on the second support plate 143 of the supports 14 and 23.

  When the bolt 352 is tightened from this state, the fastening base 351 and the fastening plate 353 gradually approach each other. When the bolt 352 is strongly tightened, as shown in FIG. 8, the bottom of the grating 3 and the top of the fastening plate 353 are fixed so as to firmly sandwich the first support plate 142 of the supports 14 and 23 from above and below. .

  When the bolt 352 is tightened as described above, it is not necessary to fix the fastening plate 353 by hand or the like. This is because the base wall 141 and the reinforcing wall 144 of the supports 14 and 23 prevent the fastening plate 353 from rotating.

  In the present embodiment, the supports 14 and 23 are also provided in a portion where the fastening portion 35 of the grating 3 is not provided. This is because the upper surface of the first support plate 142 of the supports 14 and 23 supports the bottom of the grating 3, and at the same time, the bottom of the grating 3 pushes down the decorative groove lid 2 via the support 23. This is because the receiving frame 1, the decorative groove lid 2, and the grating 3 as a whole realize a strong and stable state by applying force.

Since the groove covering structure according to the present embodiment is configured as described above, the cosmetic groove lid 2 and the grating 3 can be reliably fixed to the receiving frame 1 by an extremely simple operation. That is, in the present embodiment, both the decorative groove cover 2 and the grating 3 can be fixed to the receiving frame 1 at a time by tightening only two bolts 352.
Similarly, the fastening state can be released with a simple operation, the cosmetic groove lid 2 and the grating 3 can be removed, and maintenance such as cleaning of the groove can be performed.

  In terms of strength, the bottom of the grating 3 and the top of the fastening plate 353 are fixed by sandwiching the first support plate 142 of the supports 14 and 23 from above and below, so that a very strong structure can be realized. This will be described in detail below.

  First, the cosmetic groove lid 2 has a very large weight compared to the grating 3 because the filling member 22 is packed in the filling frame 21. Therefore, when an automobile or the like passes, the up and down movement of the decorative groove cover 2 is slight compared to the grating 3. The grating 3 can be firmly fixed using the weight of the decorative groove lid 2.

  However, although the upward and downward movement of the cosmetic groove cover 2 when a car or the like passes is slight, the weight of the decorative groove cover 2 is large, and thus the fixing groove cover 2 and the grating 3 are fixed portions. The moment applied to the support 23 becomes large. If the fixing portion is fixed by simple bolting, the bolting portion is likely to be bent or distorted due to the large moment.

  On the other hand, in the present embodiment, since the first support plate 142 of the support body 23 that is a fixing portion is firmly sandwiched from above and below between the bottom portion of the grating 3 and the upper portion of the fastening plate 353, the above-described large Even if a moment occurs, the moment is dispersed over the entire sandwiched area, so that distortion or the like is less likely to occur. In addition, when the bolt 352 is tightened, the grating 3, the first support plate 142 of the support 23, and the fastening plate 353 are three-piece integrated, and a very thick structure in which the respective thicknesses are substantially added together, Therefore, in the first place, distortion and bending are extremely difficult to occur.

  In this way, using the fact that the cosmetic groove lid 2 is a heavy object in which the filling member 22 is packed, the grating 3 can be firmly fixed, and at the same time, the connecting portion between the cosmetic groove lid 2 and the grating 3 is provided. By adopting a surface structure, the portion can be remarkably strengthened.

  As can be seen from the above, the three bodies of the receiving frame 1, the decorative groove lid 2, and the grating 3 can be firmly fixed by simply tightening the two bolts. Therefore, it becomes easy to attach and detach the decorative groove lid 2 and the grating 3 and the maintainability is improved. At the same time, even if a heavy object such as an automobile passes through, a strong structure that hardly generates rattling can be realized, so that the quietness is improved and the structure is optimal for a residential area.

  With regard to the ease of attachment and detachment, as described above, when the base wall 141 and the reinforcing wall 144 of the supports 14 and 23 are tightened or loosened in order to prevent the fastening plate 353 from rotating. In addition, since it is not necessary to fix the fastening plate 353 by hand or the like, it becomes easier to attach and detach.

In terms of maintainability, not only the decorative groove cover 2 and the grating 3 can be easily attached and detached, but the support mechanism of the grating 3 provided on the receiving frame 1 is only the support 14, and the support 14 is the side plate of the receiving frame 1. Since it is provided at the end, there is also a point of not interfering with cleaning or the like in the groove.
In addition, there is an advantage that it is difficult to steal the grating 3 only by tightening the bolt.

Embodiment 2. FIG.
The groove covering structure according to the second embodiment of the present invention is different from the first embodiment in that one end of the decorative groove lid 2 is rotatably fixed to the receiving frame as shown in FIG.
That is, the rotating shaft part 5 which is two rotatable fixed parts is provided in the vicinity of the front and rear end parts of the receiving frame 1, and the movement of the decorative groove cover 2 is restricted with respect to the receiving frame 1.

When performing maintenance in the groove, the two bolts 352 are loosened, the grating 3 is removed, and then the cosmetic groove cover 2 is pulled up to the right as shown in FIG.
Since the cosmetic groove cover 2 is a heavy object that extends over several tens of kilograms, it requires a considerable amount of force when it is pulled up, but it is somewhat smaller than removing the cosmetic groove cover 2 without using a rotating mechanism. The opening and closing work will be easier.

Embodiment 3 FIG.
As shown in FIG. 11, the groove covering structure according to Embodiment 3 of the present invention is characterized in that one end of the decorative groove lid 2 is connected by the receiving frame 1 and the opening / closing guide arm 6. Different from Form 1.
That is, two opening / closing guide arms 6 are provided in the vicinity of the front and rear ends of the receiving frame 1, and the receiving frame 1, the decorative groove cover 2, and the opening / closing guide arm 6 are respectively connected by the guide arm rotating shaft portions 7 and 8. Are connected.

FIG. 12 shows the operation when opening the decorative groove lid 2. When performing maintenance in the groove, the two bolts 352 are loosened, the grating 3 is removed, and then, as shown in FIG. 12, the cosmetic groove lid 2 is slightly lifted on the right side and then pulled up to the right side. . As shown in FIG. 11, if a lifting hole is provided at the right end of the upper surface of the decorative groove lid 2, the work can be easily advanced using a tool having a hook-like tip.
Even in the case of a cosmetic groove cover 2 that is a heavy object that spans several tens of kilograms, it can be pulled up relatively easily with a small force if it is lifted using a rotating mechanism, and maintenance can be performed. It can be made simpler. In particular, compared with the rotation mechanism shown in the second embodiment, the moving distance of the decorative groove cover 2 is long, and the upward movement is performed without greatly changing the inclination of the decorative groove cover 2, so that the decorative groove cover 2 is pulled up stably with a small force. be able to. Similarly, when closing the decorative groove cover 2, the decorative groove cover 2 can be closed with a small force and stably.
Then, the cosmetic groove cover 2 can always be closed at the correct position by the opening / closing guide arm 6. When the decorative groove lid 2 that is a heavy object is installed on the receiving frame 1 without the opening / closing guide arm 6, temporarily placed on the receiving frame 1 with rough positioning, and then the cosmetic groove lid 2 Although the position is finely adjusted, it is not easy to shift the fine groove cover 2 of several tens of kilograms, and there is a risk that the receiving frame 1 is damaged or broken.
Furthermore, compared to the configuration disclosed in the second embodiment, the cosmetic groove lid 2 can be pulled up with a more natural and easy-to-use posture and operation, thereby improving workability and safety.

  Further, the decorative groove cover 2 always faces upward, that is, the opening surface of the filling frame 21 does not face downward, so that the filling member 22 such as tile or mortar does not fall off. When the filling member 22 such as mortar becomes weakly fixed to the filling frame 21 due to secular change, and the opening surface of the filling frame 21 faces downward, the filling member 22 moves away from the filling frame 21 due to its own weight. Since it may fall off, it is very important that the cosmetic groove cover 2 always faces upward as in the present embodiment in order not to cause a major accident.

Embodiment 4 FIG.
The groove covering structure according to the fourth embodiment of the present invention is a case where the grating 3 is located at the center as shown in FIGS. That is, the decorative groove lids 9L and 9R are installed at the left and right ends of the receiving frame 1, and the grating 3 is installed in the space between them. The support 23 is provided on the right side surface of the decorative groove lid 9L and the left side surface of the decorative groove lid 9R. Therefore, the support frame 1 is not provided with a support. Other configurations are the same as those in the first embodiment.

  In this configuration, the support body 23 disposed opposite to the side surfaces of the left and right cosmetic groove lids 9L and 9R and the fastening portion 35 of the grating 3 are firmly coupled by tightening the bolts 352. Therefore, as in the first embodiment, the left and right cosmetic groove lids 9L, 9R and the grating 3 can be attached and detached with a very simple operation using the fact that the cosmetic groove lids 9L, 9R are heavy. At the same time, when the left and right decorative groove lids 9L and 9R and the grating 3 are installed, the structure is strong without rattling.

  As for the left and right decorative groove lids 9L and 9R, as in the second or third embodiment, a rotating shaft portion and an opening / closing guide arm may be provided respectively. In particular, if the opening / closing guide arm shown in the third embodiment is provided, the heavy-duty cosmetic groove lids 9L and 9R are pulled up with a natural and easy-to-use operation and relatively easily with a small force. It is possible to make maintenance easier. Further, since the decorative groove lids 9L and 9R are always facing upward when opening and closing, a serious accident such as the filling member 22 such as a tile or mortar falling off can be prevented.

Embodiment 5 FIG.
As shown in FIGS. 15 and 16, the structure of the receiving frame 10 according to the fifth embodiment of the present invention is configured such that the central beam 17 is detachable. Other configurations are the same as the receiving frame 1 in the first embodiment.
In order to make the central beam 17 detachable, as shown in FIG. 15, a plurality of pairs of fitting portions 16 are provided at positions facing each other on the left and right side plates 11L and 11R of the receiving frame 10. As shown in FIG. 16, the central beam 17 has a U-shaped cross section and can be fitted into the pair of fitting portions 16 from above. And the groove cover 2 for makeup | decoration or 9L, 9R can be installed similarly to the center beam 13 in Embodiment 1-4.

  By making the central beam 17 detachable, maintenance such as cleaning in the groove can be performed more easily. That is, when all the central beams 17 are removed after removing the decorative groove lid 2 or 9L, 9R and the grating 3 from the receiving frame, there is nothing on the opening 15 leading to the groove as shown in FIG. become. Therefore, operations such as removal of dust and gravel and washing through a hose in the groove can be performed very easily.

Regarding this feature, as shown in the first to third embodiments, the support 14 for installing the grating 3 is provided only along the side plate 11L, and it is necessary to provide a portion for supporting the grating 3 at the center of the receiving frame. Naturally, there is also no contribution. Further, in the fourth embodiment, since it is not necessary to provide the support for the grating 3 on the receiving frame at all, there is a further effect.
The attaching / detaching mechanism of the central beam 17 is not limited to the fitting mechanism shown in the present embodiment, and may be a mechanism such as screwing.

Embodiment 6 FIG.
The present embodiment relates to a garbage collection network for facilitating maintenance. This garbage collection network can basically be placed in any groove, and can collect large garbage and discard them easily.
Here, a case where a dust collection network is attached to the receiving frame 10 shown in the fifth embodiment will be described as an example.

FIG. 17 shows a dust collection net fixing portion 161, which is a groove for fixing the dust collection net 10, at the upper part of the fitting portion 16 of the receiving frame 10. It is a top view at the time of installing in a character groove. FIG. 18 is a perspective view of the garbage collection network 10.
As shown in FIG. 18, the dust collection network 10 includes a net bottom 41, a net side 42, and a fixed rod 43.

The net bottom 41 is a portion installed on the groove main body, and has a shape along the shape of the groove main body. For example, the bottom surface of the groove body may be rounded instead of flat. In that case, the net bottom 41 has a rounded shape that rises from the center to the outside along the bottom surface. That is, the net bottom 41 can be disposed so as to be in perfect contact with the bottom surface of the groove body.
The net bottom 41 is formed of a fine mesh so that small dust can be captured.

The net side portion 42 rises from one end of the net bottom portion 41 in the vertical direction. The lower half has a rough mesh to catch large garbage. Since it is a rough mesh, it will not interfere with the flow of rainwater.

In particular, the provision of the net bottom 41 makes it possible to easily dispose of the dust caught there.
Further, as shown in the fifth embodiment, since the intermediate beam 17 is installed on the upper portion of the fitting portion 16, the net side portion 42 and the fixing rod 43 of the dust collection network 10 are connected to the intermediate beam 17. It is hidden from the ground, so it cannot be seen from the ground, and it has a clean structure from an apparent point of view.
