Description

  BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a grooved cover with a receiving frame to be laid in a water collecting basin, a side ditch or the like.

The present invention relates to a receiving gutter which is disposed in a water collecting basin, a roadside or a side ditch crossing the road. The inside of the receiving frame attached to the gutter of the side groove or the upper surface opening of the water collecting basin is covered with a grooved lid having a slit so that rain water on the road surface flows into the grooved lid and drainage treatment is performed. However, in recent guerrilla heavy rain etc., there is a problem that rain falling on a road surface of a slope, for example, is not taken into the ditch, causes an overflow, and passes over the ditch surface.
Under these circumstances, inventions of grating lids have been proposed which can smoothly drain rainwater and enhance the performance of swallowing rainwater (for example, Patent Documents 1 and 2).

In addition, each figure simplifies and shows each structural member in order to make a drawing intelligible.

  The present embodiment is a grooved lid G with a receiving frame F applied to the water collecting weir 8, and comprises a grooved lid G consisting of a lid and a receiving frame F thereof (FIG. 2). The receiving frame F is installed and fixed at the upper surface opening of the water collecting basin 8 with the upper end face Fa of the receiving frame aligned with the road surface GL around it. The groove cover G is separately sized from the receiving frame F and has a size that can be detachably mounted in the receiving frame main body 6. The upper end face Fa of the receiving frame according to the grooved cover G with the receiving frame F and the upper end face of the grooved cover G are substantially flush with the road surface GL therearound.

The groove cover G is a metal disc body that covers the receiving frame F that encloses the upper surface opening of the water collecting basin 8 and includes the main member 1, the connecting member 2, the end plate 4 and the side contact member 5.
The main member 1 is also referred to as a bearing bar, and is a metal band plate-like body having a band length substantially equal to one side length of the water collecting weir 8 having a substantially square plan view. In order to produce the groove cover G, the main members 1 are arranged in parallel with each other at a constant pitch with the band width direction up and down. Here, “upper and lower”, “downward”, “horizontal direction”, and “falling” in “the main member 1 makes the band width direction up and down” in the present invention means that the groove cover G with the receiving frame F is a water collecting basin Referring to FIG. 2 installed at 8, it refers to the direction of the surface including the upper and lower sides of the paper surface, the lower side of the paper surface, the left and right front and back of the paper surface, and the downward direction of the paper surface.
In the groove cover G, a number of main members 1 align their longitudinal directions with one side direction of the water collecting weir 8 substantially square in plan view, and make the band width direction rise, as shown in FIG. 4 and FIG. It is arranged. The space between the main members 1 forms a slit width SW, and water such as rain water is passed. As the main member 1 in this case, a metal band plate having a cross-sectional shape called an I-bar, which has a thickness in the upper and lower portions as shown in FIG. 6, is used. In addition, although the unevenness | corrugation for anti-slip like FIG. 6 is formed in the upper end surface 1a of the main member 1 of this embodiment, it abbreviate | omits in another figure.

The connecting member 2 is a metal member which is formed orthogonal to the main member 11 to form a lattice with the main member 11. The connecting member 2 and the main member 1 are arranged in a lattice. The code | symbol S shows the slit made by arrange | positioning the main member 1 and the connection material 2 in a grid | lattice form. In a heavy rain etc., a large amount of rain falling on the road surface GL turns into rain water and travels toward the ditch cover G. Then, it is drawn across to the weir member 7 described later in detail, so as to cross it, and it flows into the water collecting weir 8 through the slit S.
The connecting member 2 of the present embodiment employs a metal rod-like member called a twist bar (FIG. 6). The connecting members 2 are also arranged in parallel at a constant pitch, but at the outermost side, the low-placed member 5B which is the side abutment member 5 disposed on the side of the one frame piece 61 on which the wedge member 7 is placed As shown in FIG. 4, the distance to 2A is longer than the other pitch intervals (about twice the other pitches). This is to prevent the connecting member 2 from hitting the wedge member 7 and not disturbing the wedge member 7 when the low-placed member 5B dives (FIGS. 1, 9 to 11).

The end plate 4 is a pair of band plate-like members fixed to both ends 21 of the connecting member 2 and has a band width and a band length substantially the same as those of the main member 1. The end plates 4 are erected in parallel to the main member 1 on both outer sides of the main member 1 so as to stand in the width direction of the belt. Unlike the main member 1, a flat plate may be used as the band plate body, but the end plate 4 here is the same as the main member 1. The slit width SW between the end plate 4 and the outermost main member 1 matches the slit width SW between the main members 1.
The end plate 4, the main member 1, and the connecting member 2 are the same as the components of the well-known groove cover G. After the end plate 4 and each main member 1 are erected in the band width direction and disposed at a predetermined pitch, the upper end face of the end plate 4 and each main member are separated at predetermined intervals so as to be orthogonal to these. The connecting member 2 is placed on the upper end face 1 a of the base 1. Thereafter, the end plate 4, each main member 1 and the connecting member 2 are fixed by electric pressure welding so as to form a grid, and further, the side abutment material 5 is fixed in the lateral direction on both sides. The groove lid G is assembled.

  The side application member 5 is a metal member which forms a square frame 3 close to a square with the end plate 4. The conventional groove cover G forms a rectangular frame portion with a side plate made of a flat steel strip plate, but in the present invention, the side abutment material 5 bears instead of the side plate. The portion corresponding to the slit width SW between the adjacent main members 1 uses the low position entering member 5B whose frame height 5 h is low as at least one of the two side abutment members 5 so that both sides of the main member 1 can be The side backing material 5 is fixed to 11 and the two end plates 4 form a rectangular frame 3. The both end portions of the low-placed member 5B and the strip-like side plate 5A related to the side abutment member 5 are fixed to the both end faces 41 of the end plate 4 (FIG. 4, FIG. 6). The lower portion 53 having a lower frame height 5h related to the lower portion inserting member 5B penetrates the lower end edge 76 of the wedge member 7 and the main members 1 are fitted in the respective comb-shaped notches 77 described later. Thereby, the groove cover G is configured to be accommodated in the receiving frame main body 6.

In the present embodiment, one low-placed member 5B is used on one side, and the other side 5A is a side abutment material 5 having the same shape as a conventional side plate made of a flat steel strip. The low position entering member 5B raises the band width direction of the band plate body (with the band width in the vertical direction), and arranges the low part 53 with a frame height of 5 h on the lower side in the band width direction. It is fixed to The band width of the band plate-like body relating to the side backing material 5, in other words, the frame height 5h, is the same as the band width 1W of the main member. The frame height 5h is used because it is possible to use a rod-like member with a low frame height 5h from the beginning without forming a concave groove in the side abutment member 5B constituting the rectangular frame 3.
The low position member 5B has a groove width adjusted to the slit width SW between the main members 1, and is cut low from the upper edge 5Ba to a depth exceeding the upper half 54 of the band width of the low position member 5B. The lower portion 53 is formed at the groove bottom of the recessed groove (FIG. 6). The lower portion 53 of the lower insertion member 5B allows the lower end edge 76 of the wedge member 7 to be penetrated. FIG. 5 shows that the lower portion 53 is formed by the groove bottom portion of the concave groove which is cut deeply from the upper end surface 5Ba of the lower portion containing member 5B to a depth of about 4/5 of the band width. If the depth exceeds the portion 54 (1/2 from the upper end of the band width), it is satisfied. With such a low part 53, by increasing the inclination angle of the groove cover G, the low part 53 can easily go through the lower end edge 76 of the wedge member 7 as shown in FIG. .
The reference numeral 52 denotes a support 52 which remains in the form of a band width on both sides of a concave groove in which each lower part 53 is formed from a flat plate made of flat steel, and 51 denotes a lower part of the rectangular frame 3 The base part which is a base of the low place entering member 5B which extends horizontally to the area | region of the support | pillar part 52 by fixed frame width of the groove bottom part whose frame height 5h of 53 is low is shown. The low entry member 5B may be the base 51 only forming the low portion 53 without the support portion 52. However, providing the support portion 52 is more preferable. By the support portion 52, the groove cover G can sufficiently withstand the impact in the horizontal X and Y directions generated by traveling the vehicle on the groove cover G, and contributes to preventing the main member 1 from falling down. Further, together with the end face 41 of the end plate 4, the corner of the end face 11 related to each main member 1 on the low location member 5 B side can be protected. The width 52T of the support portion 52 is provided in accordance with the thickness t of the main member 1. In the groove cover G thus completed, the upper end surface 1a of the main member 1 has non-slip irregularities, but the upper end surface Ga excluding the lower portion 53 of the lower member 5B is substantially flush. The upper edge 2a of the connecting member 2 is also substantially flush with the main member upper end surface 1a and the like by electric pressure welding.

The receiving frame F comprises a receiving frame main body 6 and a hook member 7 (FIG. 7). The receiving frame main body 6 is a metal rectangular frame having a size of an inner frame dimension in which the groove cover G fits in the frame 60. The vertical plate portion of the receiving frame main body 6 having a rectangular shape in a plan view, with one frame piece 61, another pair of frame pieces 62 facing the same, and two other frame pieces 67, with the band width of the band plate portion up and down. And the wedge member 7 is placed and fixed on the upper edge 61a of the band plate portion for one frame piece 61 thereof. A bottom plate portion 611 protrudes in an L-shape in a side view from the lower edge of the band width portion of the upstanding plate portion 612 toward the inside of the frame 60 on one frame piece 61 on which the wedge member 7 is mounted. The other frame piece 62 opposed to this also extends from the lower edge of the band width portion of the upstanding plate portion 62 toward the inside of the frame 60 with the bottom plate 621 projecting in an L shape in a side view, and receives the groove cover G housed in the inside of the frame 60 It is supported by the main body 6 (Fig. 2). The gap ε between the groove cover G placed on the bottom plate portions 611 and 621 and placed and set in the receiving frame main body 6 and each inner wall of the receiving frame main body 6 is secured 5 mm in design (FIG. 3).
One frame piece 61 on which the wedge member 7 is mounted has its upper edge cut by the thickness of the wedge member 7, and the upper end face Fa of the receiving frame F on which the wedge member 7 is placed and fixed on the one frame piece 61 is substantially flush (Fig. 2).

  The wedge member 7 fixes the base end portion 71 to be one end side in the band width direction in the frame piece longitudinal direction of the upper edge 61a of the one frame piece 61 forming the receiving frame main body 6, and also the tip end in the band width direction. It is a band plate-like body in which the portion 75 is inclined downward to a bowl shape toward the inside of the receiving frame main body 6 (inside of the frame 60). Then, a wedge member in which a plurality of comb-like cutouts 77 aligned with the disposition pitch of the main members 1 are formed toward the base end 71 side along the longitudinal direction of the strip on the lower end edge 76 side of the tip 75 It has become seven. Both ends of the wedge member 7 and the frame piece 67 form a notch 77. The wedge member 7 has its belt length equal to the length of one frame piece 61 as shown in FIG. 7 and is aligned with it, and the base end 71 is kept approximately horizontal, and the one frame piece 61 of the receiving frame main body 6 is It is placed and fixed on When the wedge member 7 is fixed to the one frame piece 61 of the receiving frame main body 6, the upper end face Fa of the receiving frame F including the upper surface of the base end 71 related to the wedge member 7 becomes substantially flush as shown in FIG. .

In the present embodiment, the base end 71 related to the wedge member 7 is formed of a horizontal portion, and the base end 71 passes over the lower member 5B of the groove cover G accommodated in the receiving frame main body 6 From the point, a tip portion 75 which slopes downward to the inside of the frame 60 extends. The wedge member 7 is placed and fixed in a T-shape on the upright plate portion 612 of the one frame piece 61 as viewed in cross section in FIG. 3, and the outer wedge portion 72 protrudes outward of the one frame piece 61. This is because the presence of the mantle 72 facilitates the alignment with the road surface GL. The proximal end 71 formed of the horizontal portion extends from the proximal end 71 to the inside of the frame 60 at a position where it extends to the inside of the frame 60 with respect to the lower member 5B of the groove cover G accommodated in the receiving frame main body 6. Directingly, the tip portion 75 having a downward slope is extended within the range of 5 ° to 50 ° (here, about 30 °).
Each of the comb-tooth-shaped notches 77 has a groove width 77 a matched to the thickness t of the main member 1. Specifically, the groove width 77a is slightly larger than the thickness t of the main member 1, and the groove depth 77b of the notch 77 passes the tip 75 from the lower end edge 76 of the tip 75 and the proximal end The depth reaches 71 points. The entrance into the notch 77 from the lower end edge 76 of the tip 75 is rounded as shown in FIG. 9 to facilitate the main member 1 to enter the notch 77. As shown in FIG. 1, when the groove cover G is assembled and set in the receiving frame F, the support portion 52 of the side abutment member 5 and the main member 1 are accommodated in the notch 77 of the base end portion 71. The upper end surface 5Ba of the insert member 5B, the upper end surface 1a of the main member 1 and the upper surface of the wedge member base end 71 are flush with each other. In the attachment set of the groove cover G to the receiving frame F, the end of the end plate 4 is accommodated in a notch 77 formed by the frame piece 67 at both ends of the wedge member 7. The upper end surface of the end plate 4 and the upper surface of the wedge member base end 71 are substantially flush.

  Further, under the state where the groove cover G is contained in the receiving frame main body 6, the lower end edge 76 of the tip end portion 75 of the wedge member 7 is disposed lower than the upper end face 1a of the main member 1, and stands upright with the bottom plate portion 611. The plate portion 612 is disposed above the bottom plate portion 611 of the one frame piece 61 formed in an L-shape in side view. An opening with a distance L is secured between the bottom plate portion 611 of the one frame piece 61 and the lower end edge 76 of the tip end portion 75 of the wedge member 7 (FIG. 3). Once the rainwater is brought into the coffin 80, the air in the space V of FIG. 3 surrounded by the one frame piece 61 of the receiving frame F with the groove G and the cocoon member 7 contained in the water collecting basin 8 is made to accompany the rainwater. , V in the space negative pressure. By setting the negative pressure, a force to draw rainwater into the weir 80 works, and the ability to draw rainwater into the weir 80 can be enhanced.

Further, as shown in FIG. 3, it is more preferable that the tip end portion 75 of the wedge member 7 projects into the frame 60 more than the bottom plate portion 611 of the one frame piece 61. This is because the air in the space V surrounded by the one frame piece 61 and the weir member 7 can be easily carried by the rainwater, and the negative pressure in a short time makes it possible to enhance the performance of the rainwater into the weir 80. Although the boundary between the proximal end 71 and the distal end 75 is shown as a bending point in FIGS. 3, 9, and 10, the distal end 75 of the main wedge member 7 is formed by bending so that the bending is performed. The points are rounded.
The code | symbol 1b shows the lower end surface of the main member 1, the code | symbol 81 shows the bottom part of a water collection basin, the code | symbol 82 shows a side, the code | symbol 820 shows a level | step-difference part, and the code | symbol P shows a conduit.

  Next, one method for attaching the receiving frame F to the groove cover G will be described. First, using the groove cover G and the receiving frame F, the receiving frame F is installed in the water collecting weir 8 so that the receiving frame upper end face Fa is aligned with the road surface GL. The receiving frame F is attached and fixed to the opening upper part of the water collecting weir 8 so that the weir member 7 is disposed on the upstream side in the rainwater flow direction. The receiving frame F is set and fixed to the top opening of the water collecting weir 8 so that the rainwater flows perpendicularly on the weir member 7. In FIG. 11, the right side of the drawing is the upstream side and the rainwater flows from the right to the left of the drawing. In the case of a slope, etc., it slopes downward to the left from the right side of the drawing.

Next, with respect to the receiving frame F in which the upper end face Fa is disposed substantially horizontally, the groove cover G is inclined downward toward the wedge member 7 so that the low location member 5B side is opposed to the wedge member 7. Subsequently, the groove cover G is advanced in the arrow direction of FIG. 11 so that the lower portion 53 of the lower end edge 76 of the wedge member 7 is covered with the lower portion member 5B placed on the bottom plate portion 611 of the one frame piece 61. When the lower portion 53 is formed by the groove bottom of the concave groove cut from the lower member upper edge 5Ba to a depth beyond the upper half 54 of the band width, the groove cover G is inclined to cause the submersion. At the time of coming off, the extra space Y can be secured between the wedge member 7 and the lower portion 53. When the low point portion 53 penetrates the lower end edge 76 of the wedge member 7, the support portion 52 of the low position member 5 B and the main member 1 enter the notch 77 at almost the same time. Further, the groove cover G is advanced, and when the column portion 52 hits the deep bottom of the depth of the notch 77, the groove cover G is changed from the inclined state to the horizontal state, and becomes the shape of FIG. The installation of the groove cover G on the end is completed. The attachment of the grooved cover G with the main receiving frame F to the water collecting basin 8 is completed. The grooved lid G with the receiving frame F is in use.
In the case of removing the groove cover G from the receiving frame F by periodic cleaning or the like, the groove cover G installed on the receiving frame F can be removed by performing an operation reverse to the above procedure from FIG. 12 to FIG.

Penetrates the lower end edge 76 of the wedge member 7 and the main member 1 is fitted into each notch 77 so that the gutter lid G is contained in the receiving frame main body 6. It can be actively introduced into the flow path 90 to enhance the rainwater entrapment performance.
The main cover F with the groove cover G is formed by the wedge member 7 having the downward inclined tip portion 75, the one frame piece 61 of the reception frame F, and the main member 1 and the low position member 5B which enter each notch 77. An enclosure space V shown in FIG. Once rainwater inflows in the direction of the arrow in FIG. 2 due to heavy rainfall or the like, the air in the enclosure space V is drawn to the flow of rainwater and taken away. When the air is taken away, the pressure in the enclosure space V is reduced, and thereafter the pressure reduction force guides the rainwater flowing on the weir member 7 to the weir 80 or the gutter channel 90 to enhance the rainwater's ability to swallow. Overflow phenomenon can be suppressed.

Since the receiving frame F and the groove cover G are separate bodies of the receiving frame F of the present invention, even if the air in the enclosure space V is taken away by the flow of rain water, the main member 1, the low location member 5B There is a space between the and the wedge members 7, and it looks as if the inside of the enclosure space V is not decompressed at first glance. Certainly, in the case of light rain, a gap may be left between the main member 1, the low position member 5B and the weir member 7, and the pressure may not be reduced. However, in heavy rainfall, the space between the main member 1 and the lower member 5B and the weir member 7 is filled by the water film of rain water. As a result, in FIG. 3, the one frame piece 61, the wedge member 7, and the main member 1 are left except for the opening formed by the distance L between the bottom plate portion 611 of the one frame piece 61 and the lower end edge 76 of the wedge member 7. The enclosure space V enclosed by the low entry member 5B is in a sealed state. When rainwater passes over the weir member 7 and flows down into the weir 80 and the side groove 9, the air in the enclosed space V is taken from the opening between the bottom plate portion 611 of the one frame piece 61 and the lower edge 76 of the weir member 7 I'm drawn by the flow and go out. As a result, the pressure in the enclosure space V is reduced.
In the present invention, the gap lid G and the receiving frame F are separated by the gap between the main member 1 and the lower member 5B and the wedge member 7, and the groove lid G from the receiving frame F is maintained smoothly. Installation and removal is possible, but since the gap is filled as described above when overflow phenomenon prevention is necessary due to torrential rain, etc., it can be fully utilized. In addition, although the gap is not filled up with light rain, there is no problem because the overflow phenomenon does not occur. When it is necessary to suppress the overflow phenomenon while it is possible to carry out the removal work of the gutter lid G from the receiving frame F and the return operation after the cleaning separately by periodic cleaning etc. as described above, it is needless to say It is an invention that can demonstrate its power and is extremely rational.

  Then, in place of the general-purpose product, the present receiving frame F-equipped groove cover G is prepared by preparing one low-placed member 5B and one wedge member 7 and slightly scraping the upper edge 61a of one frame piece . A single piece of lower part member 5B and a single piece of wedge member 7 can be easily manufactured by press processing, laser processing or the like, and instead of the known parts, these two deformed parts are assembled with other known parts to simplify A groove cover G with a main receiving frame F is completed. Compared with the overcutting prevention guide for grating disclosed in Patent Document 1, which requires many guide members to be prepared, one plate must be attached and fixed between the main bars, and the cost is high, the product of the present invention is Production is easy and low cost production is possible.

Further, in the conventional product including the patent document 1, there is a gap ε between the receiving frame F1 and the grating lid GR in handling, causing the vortex flow and turbulence in the flow of the flowing water in the gap ε Although there is a possibility that the capacity may be reduced, this is not the case with the grooved cover G with the receiving frame F.
Of course, a gap ε also exists in the main cover F with the groove cover G (FIG. 3). However, the gap ε is completely covered by the wedge member 7 which is flush with the road surface GL. The base end portion 71 related to the wedge member 7 is formed of a horizontal portion, and the base end portion 71 passes the low-placed member 5B of the groove cover G accommodated in the receiving frame main body 6, and from this point Tilt downward to 60. Since the base end portion 71 of the wedge member 7 covers the gap ε formed between the receiving frame F and the groove cover G placed in the frame 60 and reaches the groove cover G, generation of an eddy current or rainwater due to the gap ε There is no flow disturbance. When rainwater enters the gutter 80 and gutter 9 via the gutter lid G with the main receiving frame F due to guerilla heavy rain etc. as shown by the arrows in FIG. 2 and FIG. Since it is covered, the generation of an eddy current or disturbance of the flow of rain water due to the gap ε does not occur. Since the gap ε is covered with the wedge member base end 71 which has a plate shape flush with the road surface GL and the upper surface is smooth, rain water of the road surface GL forms a stream line ST on the base end 71 and flows And without disturbing the stream line of rainwater, it is smoothly taken into the weir 80 and the gutter channel 90 across the weir member 7.

  Furthermore, as in Patent Document 2, the side groove 9 is grating installed lower than the road surface GL, and there is no risk of giving impact to a pedestrian or a traveling vehicle due to the formation of a step portion. The main cover F with groove cover G is substantially flush with the upper surface opening of the water collection weir 8 and the side groove 9 so that the upper end face Fa of the support frame and the upper end surface Ga of the cover G are aligned with the road surface GL around it. Because it is installed, no step is created. There is a wide scope of application regardless of the roadway, sidewalks, etc.

  In addition, the grooved cover G with the receiving frame F is excellent in terms of safety even from another point of view. The lower part 53 of the lower member 5B penetrates the lower end edge 76 of the wedge member 7 and the gutter lid G is contained in the receiving frame main body 6, so that rainwater in the gutter lid and the gutter 9 flows back and blows up due to heavy rain. Even if a situation occurs, the groove cover G does not come off. Once the gutter lid G is once stored in the receiving frame main body 6, the gutter member 7 of the gutter member 7 is engaged with the lower portion 53 of the gutter member 7B even if the gutter lid G receives the force of reverse flow of rainwater. I can not get out of the 60s. Moreover, since the tip end portion 75 is inclined downward toward the inside of the frame 60, the tip end portion 75 exerts a return function to lock, and the low position entering member 5B prevents the groove cover G from coming off from the receiving frame F. There is a receiving frame F with a groove cover G extremely excellent in terms of safety measures. It is possible to prevent an accident in which the gutter lid G is detached by heavy rain and falls or falls into the water collecting weir 8 or the gutter 9.

Furthermore, when the low portion 53 is formed at the groove bottom portion of the concave groove cut from the upper edge 5Ba to the depth exceeding the upper half portion 54 of the band width, the groove cover G is formed. The lower portion 53 can penetrate through the lower end edge 76 of the wedge member 7 without difficulty. It leads to the improvement of the attachment workability of the groove cover G to the receiving frame F. Even if the low location portion 53 is provided, the post portion 52 is fixed to the end surface 11 of the main member 1 by providing the post portion 52 forming the concave groove on both sides of the groove bottom portion for the low portion 53. Since the necessary strength of the groove cover G is sufficiently secured, there is no problem.
As described above, the grooved cover G with the receiving frame F exerts the above-mentioned many excellent effects, and has become an innovative product which has never been seen before.
