DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a groove cover which is fixedly mounted on a concrete gutter manufactured in a factory. The groove is formed so that the entire exposed upper surface of the gutter is covered with a protective plate having an integral slip surface. A plate is integrally formed on both sides of the lid, and
The groove cover is bolted to a concrete gutter at the same plate portion.

[0002]

2. Description of the Related Art Conventionally, there is a structure in which a groove cover is fitted into a receiving frame embedded in a concrete gutter, and further has a structure in which a shoulder portion of the receiving frame is extended and the entire upper surface has a non-slip pattern. .

[0003]

One of the drawbacks of the concrete gutter is that the corners are easily chipped by external force. In particular, it is used for a long period of time, and also has a great effect on deterioration. Conventionally, there is a technology in which the shoulder of the receiving frame supporting the groove lid is extended and the upper surface is configured to have an integral slip surface, but it is essentially a separate structure from the groove lid, and a fixed structure and In order to achieve this, it is necessary to separately provide a structure in which bolting structures are combined, and it is a technical problem to be solved to provide a structure in which these are combined to form an integrated structure.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention comprises a groove cover body having a strength member as a road construction member and having an opening through which rainwater and the like can pass. The groove cover main body is to be loosely fitted into the opening of the concrete gutter supporting the groove, and the plate-shaped support portion is integrally formed outwardly from the upper surfaces of the two sides of the groove cover body so that the entire upper exposed portion of the concrete gutter is formed. A notch formed at the outermost end of the plate-shaped support portion, the cut-out portion corresponding to the bending formed at the outermost end of the plate-shaped support portion; Is formed outside the concrete gutter, a through-hole having a recess for burying a nut is formed in a part of the plate-shaped support portion, and a recess is formed at a portion of the concrete gutter corresponding thereto. Characterized by implanting anchor screws on the To. Another invention is to provide an end plate as a road construction member, comprising a groove cover body formed by sheet metal grating, and to loosely fit the groove cover body into an opening of a concrete gutter supporting the groove cover body. None, a plate-shaped support portion integrally formed outwardly from the upper surface of the two end plates of the groove lid body so as to entirely cover the upper exposed portion of the concrete side groove, and the outermost end is bent; A notch corresponding to the bending formed at the outermost end of the plate-shaped support portion, the cut-out portion being formed on the outer surface of the concrete side groove; Is formed with a through-hole having a concave portion in which a nut is embedded, and a concave portion is formed in a portion of the concrete side groove corresponding thereto, and an anchor screw is implanted in the concave portion.

[0005]

The operation of the present invention will be described in more detail by providing a plate-shaped support portion integrally having a dimension covering the entire upper exposed portion of the groove cover main body, which is a strength member, and a concrete gutter supporting the groove cover body. The concrete part is reinforced, and dust enters the gap formed between the groove cover body and the receiving frame, which hinders the opening operation.However, the groove cover body and the receiving frame are integrated. By doing so, the gap which causes the problem is eliminated, and the bolt is fixed to the side groove by bolts.

[0006]

An embodiment of the present invention will be described with reference to the drawings.
In FIG. 1, reference numeral 1 designates a strength member, a groove cover body having an opening through which rainwater and the like can pass, and 2 a plate integrally implanted on both sides from two upper surfaces which are supporting sides of the groove cover body. State bearing,
Reference numeral 3 denotes an integral non-slip pattern formed on the surface of the plate-like support portion 2. Reference numeral 4 denotes a shoulder portion 5 for supporting the plate-like support portion 2 and an opening 6 into which the groove cover main body 1 is loosely fitted. A concrete gutter, the plate-like bearing portion 2 is dimensioned to cover the entire shoulder 5 of the concrete gutter 4, and the outermost end is bent 7;
Further, a through-hole 10 having a recess 9 in which the nut 8 is buried is formed in a part of the plate-like support portion 2, and a recess 11 is formed in a corresponding portion of the shoulder 5 of the side groove 4 made of concrete. An anchor screw 12 is implanted and assembled as shown by the arrow. FIG. 1 shows a groove cover made of ductile cast iron or the like, but FIG. 2 shows another embodiment in which a groove cover body 21 is formed by sheet metal grating, and the groove cover main body 21 is formed from an upper surface of two sides of an end plate 22. On the other hand, a plate-like bearing portion 23 is integrally implanted on both sides, 24 is a non-slip pattern, 25 is a concave portion in which the nut 8 is embedded, and 26 is a through hole through which the anchor screw 12 is inserted. .

[0007]

As described above, according to the present invention, the groove cover main body, which is a strength member, is loosely fitted into the opening of the concrete gutter, and a plate-like support is integrally implanted with the opening. The shape bearing portion is configured to have a dimension that entirely covers the upper exposed portion of the shoulder, which is the bearing surface of the concrete gutter,
This eliminates the need for the previously required receiving frame, which facilitates the manufacture of concrete gutters,
Dust enters the gap created between the groove lid body and the receiving frame,
This hinders the opening operation, but the problem is solved by the integral structure.Furthermore, the laying state of the groove lid main body is immobilized by fixing it to the side groove with bolts at the plate-like support portion. And without causing unusual deviation,
It is highly practical and useful.
