Description

The present invention relates to a grating receiving frame that is installed in a road gutter, a waterway, or the like and to which grating is mounted, and is attached to a road gutter or the like such as rainwater to which the grating is mounted.

When repairing, maintaining, or repairing concrete lids such as road gutters and waterways in civil engineering work, after cutting and excavating existing gutter concrete and road asphalt around it, a grating receiving frame is installed to form a slab type. It is common to perform processes such as frame curing and backfilling and install new grating (see, for example, Patent Document 1).

In this type of grazing receiving frame, the anchor protrudes in the cutting direction of the road gutter concrete and the road asphalt around it, and interferes with the existing road gutter concrete and the road asphalt around it. It needs to be scraped.

JP-A-2005-307484

In the conventional installation work of the receiving frame for grating described above, the receiving frame for grating is installed after cutting and excavating the existing road gutter concrete such as rainwater and the road asphalt around it for burying the anchor of the receiving frame. Since there are processes such as slab formwork curing and backfilling, it takes about one month for the construction period, and in addition to the increase in labor costs and other costs, the risk increases due to obstruction of traffic, dust scattering, etc. The burden on the residents was great.

The present invention is intended to solve the problems of such a conventional construction method, and is used to cut, excavate, and slab type existing road gutter concrete such as rainwater and road asphalt around it for construction. By eliminating the need for processes such as frame curing and backfilling, the construction period can be significantly shortened to several days, labor costs and other costs can be reduced, and same-day traffic is possible, so areas such as danger avoidance and dust scattering The purpose is to provide technology that can significantly reduce the burden on residents.

The grazing receiving frame of the present invention is a grating receiving frame installed in a groove on a road side, a waterway, or the like to which grating is mounted, and includes a horizontal piece 12 and a vertical piece 13 that is connected to the end of the horizontal piece 13 to form an L shape. The member 11 composed of the member 11, the vertical piece 16, and the member 14 composed of the horizontal piece 15 connected to the lower end portion thereof to form an L shape are horizontal so that the member 11 has a tubular shape. The end of the piece 12 and the side surface of the vertical piece 16 of the member 14 are joined, and the end of the vertical piece 13 of the member 11 and the vicinity of the end of the bottom surface of the horizontal piece 15 of the member 14 are joined. Cover the frame 10, the frame 20 arranged in the same structure as the frame 10 so as to face the frame 10 in a line-symmetrical manner, and the tubular openings of the frame 10 and the frame 20. The frame 30 is a band-shaped member that connects the frame 10 and the frame 20 in parallel, and the frame 10 and the other tubular opening of the frame 20 are covered so as to be parallel to the frame 30. A frame 40 that connects the frame 10 and the frame 20 in parallel is provided, and the frame 30 and the outer side surface of the frame 40 that do not interfere with the road side groove or the like when attached to the road side groove or the like are provided. The first feature is that the shape anchor 5 is provided.

Further, in addition to the above-mentioned first feature, the grating receiving frame of the present invention has a second feature that the frame 10 and the bottom outer edge portion of the frame 20 have a rounded shape.

The fourth feature is that both ends of the L-shaped corners and the corners of the frames 30 and 40 are cut off to provide openings.

In addition, claims 1 to 4 are a method of installing a grating receiving frame in which grating is attached to a road gutter or a water channel in a road gutter or a water channel at a position that does not interfere with the existing gutter concrete of the road side or the water channel. After the grating receiving frame according to any one of the above items is placed on a lid resting portion such as a road gutter or a waterway, a protruding anchor portion provided with the grating receiving frame is driven to existing a road gutter or a waterway. The fifth feature is to fix and install the grating receiving frame at a position that does not interfere with the gutter concrete.

According to the grating receiving form according to claim 1, since the construction can be performed without scraping the existing gutter concrete and road asphalt, the existing stability is achieved by excavating and backfilling as in the conventional technique. In addition to being able to perform construction without losing ground strength, the slab formwork curing process can be reduced, which can significantly shorten the construction period, reduce construction costs, and reduce the burden on residents.

Further, according to the grating receiving frame according to claim 2, in addition to the action and effect according to claim 1, the bottom outer edge portion of the frame 10 and the frame 20 has a rounded shape, so that the gutter concrete has a rounded shape. In addition to being able to be installed favorably even if the concrete lid resting part is distorted, the guttered concrete has a shape that can secure a space for the earth and sand to escape even if it accumulates on the concrete lid resting part, so that it is not rattling and is preferably installed. Can be done.

Further, according to the grating receiving frame according to claim 3, in addition to the effects according to claims 1 to 2, the existing gutter concrete lid resting portion is distorted and the installation load area is reduced. Even if it is, the ground contact area can be secured to the maximum and it can be installed suitably.

Further, according to the grating receiving frame according to claim 4, the moisture that has entered the inside of the frame 10 and the frame 20 can be suitably discharged, and the member can be protected from corrosion and the life can be significantly extended. In addition, it is possible to reduce the time and effort required to process the frame 30 and the frame 40 so as to match the shapes of the frame 10 and the bottom outer edge portion W of the frame 20.

According to the method of installing the grazing receiving frame according to claim 5, steps such as cutting, excavating, slab formwork curing and backfilling of existing road gutter concrete such as rainwater and road asphalt around it for construction work. It is unnecessary, the construction period can be shortened to several days, labor costs and other costs can be reduced, and existing road asphalt and road ground are not excavated and backfilled, so uneven subsidence of road ground after construction does not occur. In addition to being able to carry out construction on the same day, it is possible to avoid dangers such as when passing on one side, and the burden on local residents such as dust scattering can be greatly reduced.
