DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grating mounted on a gutter block. In particular, it relates to grating for preventing noise.

[0002]

2. Description of the Related Art In order to solve the problem of insufficient drainage capacity of a concrete lid usually placed as an upper lid of a gutter block, a steel grating having a large opening is usually installed at regular intervals instead of the concrete lid. You.

[0003] There are various methods of mounting the grating, and a so-called raised type installation method is generally to mount the grating on the receiving portion of the concrete lid of the gutter block as shown in FIG. It is.

However, there is a disadvantage that the rattling cannot be suppressed only by placing the grating on the receiving portion as shown in FIG. The reason is that the side groove block is not manufactured with strict dimensional accuracy so as to prevent rattling, and in addition, the grating itself also suffers from poor welding accuracy at the time of manufacturing and deformation of the steel material due to welding heat. Because. Due to such various factors, it is difficult to form the support member and the receiving portion in a planar shape so that there is no backlash.

As described above, it is very difficult to mount the grating and the receiving portion of the gutter block completely in close contact with each other without rattling. , A gap is generated and rattling occurs. Further, as shown in FIG. 20, a gap is also formed between the side surface of the side groove block and the side surface of the grating, and rattling occurs in the lateral direction. Such rattling causes noise when a car or truck runs.

Therefore, conventionally, as shown in FIGS. 21 and 22, another means, such as a rubber for preventing noise, which securely fixes the grating to the side groove block by a bolt or the like to prevent rattling, is used. The generation of noise was prevented by means such as sticking to reduce the contact noise.

[0007] However, such a method requires extra work steps such as bolting and rubber attachment, complicating the laying work, and also incurs costs for parts such as bolts and rubber. There was a problem that the construction cost became expensive.

In this way, it is possible to securely fix even the side groove block and the grating which are difficult to obtain the accuracy. The shape of the tongue piece is not particularly limited, and the tongue piece can be sheared into various shapes such as a square and a U-shape. Further, the direction in which the tongue piece is bent may be any direction such as upward or downward. In particular, by adopting a means of bending and projecting the tongue piece, the amount of protrusion can be easily adjusted by adjusting the amount of bending. Therefore, it is possible to quickly and easily cope with the variation of the receiving portion of the concrete product. In this way, it is extremely difficult to make contact with a surface or a line, and it is not necessary to determine the location of contact between the concrete receiving part and the inclined surface of the grating. become able to. In addition, the adjustment of the protruding portion may be performed by aligning the product with the gutter block to be actually installed, and after the adjustment is completed, the middle or / and the outside of the protruding portion may be securely fixed by welding.
It may be used simply by placing it without any adjustment. If used without welding, the tongue can gradually adapt to the receiving portion of the gutter block over time and be fixed.

Further, a gap is formed between the support member other than the tongue and the concrete receiving portion by the four-point support by the tongue. The gap is filled with sand, gravel, or the like, or is naturally filled, so that more secure fixing is performed.

Further, in order to more positively prevent rattling in the lateral direction, protrusions 23 can be formed on both side walls of the lid body 10. By providing the projections 23, rattling can be prevented.

Further, a deviation preventing protrusion is provided on the support member to further effectively prevent the deviation. In this case, by forming the deviation preventing member in a V shape, deviation in the vertical direction can be prevented.
