Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to general roads and streets,
The present invention relates to a mounting structure for attaching grating to an upper end opening of a gutter laid in a park or the like.

[0002]

2. Description of the Related Art The applicant of the present invention has a top wall-integrated sewer having many features, such as a higher sweeping effect than a normal U-shaped gutter, and excellent layability and scenery after laying. A groove has been devised and already in practical use.

[0003] Fig. 7A is a front view showing a joint portion of a conventional sewer-shaped gutter, and Fig. 7B is a sectional view taken along line BB of Fig. 7A.

[0004] As shown in the figure, a drain channel 02 having a substantially oval cross section and an opening at the center of the upper surface is formed inside a block-shaped side groove main body 01 having a substantially rectangular parallelepiped shape. In addition, a slit-shaped flowing water port 03 communicating with the drainage channel 02 is provided at the center of the smooth top wall 01a of the gutter main body 01.
It is formed along the longitudinal direction.

[0005] In the upper surface of the top wall 01a, in the vicinity of the water outlet 03, a pair of lower horizontal pieces of a pair of left and right grating mounting brackets 04, each of which has an L shape, is provided with a plurality of bolts 05.
A plurality of grating supporting pieces 06 bent downward in an L-shape are fixed at required intervals in the longitudinal direction at an intermediate portion between the opposing surfaces of both brackets 04.

[0006] A grating 07 is provided on the upper surface of each grating support piece 06 between the two brackets 04 so that the upper surface and the upper surface of the bracket 04 are flush with each other.
A bolt 08 inserted from above the grating 07 is screwed into a nut 09 previously fixed to the lower surface of each grating support piece 06, so that the bolt 08 is detachably attached.

[0007] As described above, the grating 07 is provided on the top wall 01.
In the case of a raised gutter attached above the upper surface of a, only the opening of the grating 07 is exposed, and all other portions are buried and buried in the soil or asphalt for pavement.

[0008]

As described above, when a plurality of grating support pieces 06 are fixed to the opposing surfaces of the two brackets 04 and the gratings 07 are mounted thereon, the sediment and the like accumulated in the drainage channel 02 can be obtained. In the removal work, high-pressure washing, etc., or the collection of fallen objects, the fixedly attached grating support piece 06 hinders operation efficiency.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has a structure for mounting a grating in a gutter in which the drainage can be easily cleaned by modifying a supporting form of the grating. It is intended to provide.

[0010]

In order to achieve the above-mentioned object, the mounting structure of the grating in the side groove according to the present invention comprises:

a, 4b, two brackets 5a, 5b
Is provided with a downward stopper piece 10 which comes into contact with the locking pieces 7a and 7b when the
Since the two brackets do not greatly expand, there is no possibility that the grating 14 received by the two guide members 6a and 6b will fall off.

Further, on the upper surface of the mounting plate 7, when both brackets 5a, 5b are going to be deformed inwardly, a restraining piece 12 which comes into contact with each guide member 6a, 6b or a stopper piece 10 provided thereon is provided. Since the brackets 5a and 5b are provided, the brackets 5a and 5b are largely deformed inward due to earth pressure or the like, so that it is possible to prevent the grating 14 from being strongly pressed. Therefore, it is not difficult to remove the bracket 14.

In addition, since the grating 14 can be easily attached and detached by the bolt 16 and is firmly fixed to the nut 13 of the mounting plate 7, there is no possibility that the grating 14 will jump.

Next, a modified example of the relationship between the mounting plate and the guide member that supports the mounting plate in the present embodiment will be described.

That is, as shown in FIG. 5, the guide members 20a and 20b are formed by a pair of upper and lower corner members 8 and 9 fixedly spaced apart along the facing surfaces of the brackets 5a and 5b. , 4b, and a plate-like stopper piece 10 is fixed to the lower corner member 8 upward so as to cover a part of the concave grooves 4a, 4b in the longitudinal direction.

The mounting plate 18 is bent downward on both sides in the width direction formed in a rectangular shape in plan view to form bent pieces 18a and 18b as locking pieces that can be fitted and supported in the concave grooves 4a and 4b. The height of the bent pieces 18a and 18b is shorter than the interval between the concave grooves formed by the pair of upper and lower corner members 8 and 9.

The mounting plate 18 includes two bent pieces 18a, 18
A restraining piece 12 made of a square plate having a predetermined thickness is fixed to the lower surface between the two bent pieces 18 by welding or the like.
A predetermined gap is formed between the inside of a and 18b and both sides of the restraining piece 12.

Further, the mounting plate 18 is provided with an insertion hole 11 which penetrates the restraining piece 12 from the center upper surface thereof.
A nut 13 is fixed to the insertion hole 11 formed on the bottom surface of the slab.

The mounting plate 18 is provided on both sides of the restraining piece 12 fixed to the lower surface between the two bent pieces 18a and 18b and the two bent pieces 18a and 18b.
A concave groove having a predetermined gap is formed inside each of a and 18b.

Therefore, both ends of the mounting plate 18 are
a, 4b, both folded pieces 18
The upper end of the upward stopper piece 10 faces a recess formed by the inside of the a and 18b and the both side faces of the restraining piece 12.
