Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a lid receiving structure for a gutter block installed on a road shoulder or the like.

[0002]

[Prior art]

 Conventionally, as a lid receiving structure for a gutter block, for example, a structure as shown in FIG. 5 is known. In this conventional structure, an opening 102 is formed between the upper end surfaces of the left and right side walls 101, 10 that face each other across the groove 100, and the lid member is provided between the upper ends of the left and right side walls 101, 101 so as to cover the opening 102. 200 is mounted and supported, and angle members 103 and 103 having an L-shaped cross section are attached to the upper end surfaces of the left and right side walls 101 and 101, and the lid member 200 is fitted inside the angle members 103 and 103. It was a thing. Therefore, in this lid receiving structure, the displacement of the lid member 200 in the width direction can be restricted by the angle mold members 103.

[0003]

[Problems to be solved by the device]

 However, the conventional lid receiving structure has the following problems. In order to attach the angled shape member 103 to the upper end face of the side wall 101, it is necessary to provide the angled member 103 with an anchor portion 104 and insert the anchor portion 104 into the upper end portion of the side wall 101. For this reason, it is troublesome to attach the angled shape member 103, and it is necessary to provide the angled shape member 103 over the entire length of the upper end surface of the side wall 101, which is disadvantageous in terms of cost.

Since the lid member 200 is fitted inside the angle mold members 103, 103, the lateral width T1 of the lid member 200 needs to be narrower than the inner width T2 between the angle mold members 103, 103 to provide a fitting margin. There is a gap between the lid member 200 and the angled mold member 103 due to this fitting margin. Therefore, this gap causes rattling in the mounted and supported state of the lid member 200. Further, when rainwater enters through the gaps, rust is generated on the angle mold member 103, and particularly when the rust spreads to the anchor portion 104, this causes cracks on the side wall 101. Further, an inward load P acts on the side wall 101 due to earth pressure, passage of a large vehicle, or the like. However, if the lid member 200 is loosely mounted and supported, the inward load P is supported by the lid member 200. However, the side wall 101 falls inward and causes cracking.

The present invention focuses on the above-mentioned conventional problems, has a simple structure, and has a lid for a gutter block which is capable of being placed and supported between the upper ends of the left and right side walls without rattling. The challenge is to provide a receiving structure.

[0006]

[Means for Solving the Problems]

 In order to solve the above problems, the gutter block lid receiving structure of the present invention has an opening formed between the upper end surfaces of the left and right sidewalls that face each other across the groove, and the left and right sidewalls cover the opening. Is a lid receiving structure of a gutter block for mounting and supporting a lid member between upper end surfaces of a main body side taper hole is formed in the upper end surfaces of the left and right side walls, and the main body side taper hole corresponds to the lid side. A taper hole is formed on the bottom surface of the lid member, and a taper pin fitted between the main body side taper hole and the lid side taper hole is provided between the upper and lower surfaces of the left and right side walls and the bottom surface of the lid member. There is.

[0007]

[Action]

 In the present invention, the taper pin is fitted in the body side taper hole formed in the upper end surfaces of the left and right side walls, and then the lid side taper hole formed in the bottom surface of the lid member is fitted in the taper pin. Thus, the lid member can be placed and supported between the upper end surfaces of the left and right side walls. As described above, the lid receiving structure of the present invention has a simple structure in which the taper pin is fitted into the main body side taper hole and the lid side taper hole, and since the taper hole and the taper pin are fitted together, The fitting can be done easily.

Further, since the taper pin is fitted between the upper end surfaces of the left and right sidewalls and the bottom surface of the lid member, the taper pin is fitted over the main body side taper hole and the lid side taper hole. There is no problem such as backlash or rainwater intrusion. In addition, since the lid member is free from backlash, the inward load acting on the side wall can be supported by the lid member, and the occurrence of cracks due to the side wall falling inward can be prevented.
