Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a grating device for a gutter having an opening narrower than a channel in an upper portion of a main body.

[0002]

[Prior art]

 This type of gutter grating is installed on a gutter buried under the surface of the ground to protect the gutter and drain the upper part of the pavement surface. However, it is not compatible with permeable roads and other pavement surfaces, and there has been a problem that infiltrated water cannot be drained efficiently.

[0003]

[Problems to be solved by the invention]

 The present invention has been made in view of the above points, and a problem thereof is to enable efficient drainage of water that has penetrated a permeable pavement surface.

[0004]

[Means for Solving the Problems]

 In order to solve the above problem, the present invention provides a grating side frame having a base frame portion disposed on the main body on both sides of the opening, and a rising portion rising from the base frame portion on both sides of the opening. And a grating lid disposed between the rising portions to cover between the side frames, and in a state in which the permeable pavement surface is filled with pavement up to the upper portion of the side frame, the water permeated from the pavement surface. A means to guide the water to the channel is provided at the bottom of the grating frame.

[0005]

[Embodiment of the invention]

 The grating device for gutters according to the present invention is a grating device for applying to a gutter having an opening narrower than a channel in an upper portion of the main body. The grating device includes a grating composed of a pair of side frames having a base frame disposed on the main body on both sides of the opening, and a rising portion rising from the base frame on both sides of the opening, and covering between the both frames. And a grating lid arranged between the rising portions. The grating lid corresponds to a porous lid typified by a lattice, and the side frame supports the position where the grating lid is to be placed. Further, since the side frame also has a role of installing the grating device on the main body of the side groove, the side frame has a mounting means on the side groove such as a bolt.

In the grating frame, it is desirable that a side frame composed of a base frame portion and a rising portion arranged on both sides of the opening is connected and integrated. This is because the positioning with the gutter is easy. However, the present invention can be applied to the case where the base frame and the rising portion on both sides of the opening are completely separated.

[0007] In such a grating device, in a state where the filled pavement is formed up to the upper side frame by the permeable pavement surface, a water guiding portion for guiding water permeated from the pavement surface to the water channel portion is provided with a grating frame. Provided below the The water guiding section may be any shape and structure as long as it can guide the water permeating the permeable pavement surface from the outside to the water channel section. However, since water-permeable pavement often contains materials such as sand and gravel, it is necessary to prevent the passage of these particulate materials and to provide a filter that allows only water to pass or a flow stop for the particulate materials in the water conveyance section. It is desirable.

【Example】

 Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiments. FIG. 1 shows a plan view and a side view of a grating frame of a grating device 10 for a gutter according to the present invention. As shown in FIG. 5, the main body 11 has a water passage portion 12 having a circular cross section and an opening portion 13 having a smaller width than that of the water passage portion 12, and the water flowing from above is taken into the water passage portion 12 from the opening portion 13. It has a structure that can be. The main body 11 is a fixed-length object, and has a water passage portion 12 and an opening portion 13 penetrating therethrough in the longitudinal direction. On the upper surface, insert nuts are provided on the left and right sides of the opening portion as coupling means 14 for grating. .

The grating 15 includes a pair of side frames 18 having base frames 16, 16 disposed on both left and right sides of the opening 13 and rising portions 17, 17 rising from the base frames 16, 16 on both sides of the opening. And a grating lid 21 disposed between the rising portions to cover the space 20 between the side frames. The grating lid 21 has a water intake 22 as a whole. The pair of left and right side frames 18, 18 are joined and integrated by a joining portion 23 provided at an intermediate position of the rising portion. The joining portion 23 provides a receiving portion for mounting the grating cover 21 thereon. And a flowing water port 24 through which water flowing from the intake port 22 of the grating lid 21 flows downward.

The side frame 18 has a bolt hole 26 at a position corresponding to the coupling means 14 for passing a bolt shown as a coupling partner 25 to the coupling means 14. The upper surface of the grating 15 placed on the joint between the pair of left and right side frames 18 and 18 is almost flush with the upper ends of the rising portions 17 and 17. It is almost as high as the pavement surface (see FIG. 5).

Then, in order to guide the water permeated into the pavement material 27 outside the side frame to the waterway section 12, a water guide section 28 is provided at a portion from the lower portion of the side frame 18, which is a lower portion of the grating frame, to the base frame portion 16. Is provided. The illustrated water guide 28 is shown in a vertically elongated slit shape (FIG. 1B). In order to stop the passage of the granular material through the water guide 28, a filter is provided outside the water guide 28 as an outflow stopper 29.

The grating cover 21 is formed as a fixed-size object having the same size as the main body 11 of the side groove together with the side frame 18, but the side frame 18 is installed on the main body, whereas the grating cover 21 is Take a structure that is connected with each other. As this connection structure, a projection 31 is provided at one end in the longitudinal direction of the grating lid 21, and a recess 32 is provided at the other end for receiving the projection 31. , 32 are fixed by bolts 33 and connected. Reference numeral 34 denotes a bolt through hole, and a female screw 35 is provided on the projection 31, for example. But this could be a nut. Note that a cap or the like for preventing mud clogging is provided in the concave portion 36 around the bolt 33.

Therefore, in a state where the present invention device 10 is installed on the main body of the gutter, and only the upper end portion thereof is left to be filled and paved with the permeable pavement material 27, as shown in FIG. When the water penetrates into the granular pavement material 27 made of sand and gravel or the like, the water can easily enter the grating frame 18 from the water guide 28 (see FIG. 5). In installing the device 10 of the present invention, the grating 15 has an integral structure, so that it is only necessary to put the device on the main body, adjust the position, and fix it with bolts. However, the presence of the connecting portion 23 of the grating 15 hinders the cleaning of the circular waterway portion 20, and in order to increase the time and effort, it has been experimentally studied to form a connecting portion that is weak enough to be removed by hitting with a hammer after installation. , And received a fair evaluation. Therefore, such a structure having a weakly bonded portion is also within the scope of the present invention.

[0014]

[Effect of the invention]

 Since the present invention is constructed and operates as described above, by installing on a permeable pavement surface, water that has penetrated into the pavement surface can be guided from the headrace section to the main body waterway section. This has the effect of enabling efficient drainage.
