Abstract

PURPOSE: To place a cover plate surely by a method wherein vertical ditches are formed along right and left sidewall end faces, horizontal ditches along a top plate section are formed while being crossed with the vertical ditches and stepped sections for putting on a cover at the upper ends of right and left sidewalls are formed in a hole section for placing the cover plate. CONSTITUTION: Sidewalls 2 are mounted in parallel right and left while a top plate section 3, in which haunches 3a are formed at the corner sections of a rear, are installed while being crossed between the upper ends of the sidewalls 2, thus forming the main body 1 of a block for a street gutter. Vertical ditches 5 are formed along the end faces of the right and left sidewalls 2 of the main body 1 while horizontal ditches 6 along the top plate section 3 are shaped as being crossed with the vertical ditches 5. A hole section 4 for placing a cover plate is formed to the top plate section 3 while stepped sections 2a for putting on the cover plate are formed by the top plate 3 and the upper ends of the right and left sidewalls 2, and haunches 7 for placing the cover plate are formed along the stepped sections 2a from the sidewalls 2. The cover plate 8 is fitted into the hole section 4, and borne by the stepped sections 2a and the haunches 7.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gutter block installed along a side edge of a road for draining rainwater and the like.

[0002]

2. Description of the Related Art Heretofore, in this type of gutter block, an example in which a tenon in the vertical direction is provided in an end face portion for joining with an adjacent block is seen. Further, in order to mount a lid plate that closes the hole formed in the top plate portion, it is common to provide it on the upper end of the side wall of the opening at the step.

[0003]

However, in the case where only the vertical tenon is provided in the end face portion for joining with the adjacent block, there is a possibility that the adjacent blocks may be displaced upward or downward due to uneven settlement or the like. there were. Further, only providing a step on the upper end of the side wall for mounting the cover plate has a drawback in strength. That is, since the mounting area is small, there is a drawback in strength with respect to receiving a load such as a vehicle, and mounting of the lid plate is uncertain, which may cause rattling.

The present invention was developed in order to solve the above-mentioned problems, and the side grooves formed so that the adjacent side groove blocks can be surely connected to each other without being displaced and the lid plate can be surely placed. The purpose is to provide a block for use.

[0005]

In order to achieve the above object, according to the present invention, a top plate portion is provided across the left and right upper ends, and a hole for mounting a lid plate is provided on the top plate portion. In the provided gutter block, a vertical groove is provided on the end surface along the left and right side walls, and a horizontal groove is provided along the top plate portion so as to intersect with the vertical groove. In the section, left,
A step portion for placing the lid plate is provided on the upper end of the right side wall,
A haunch for mounting the lid plate is projected inward from the left and right side walls.

Further, the cover plate mounting haunch is one in which the cover plate mounting hole extends inward from the left and right side walls at the center in the lengthwise direction or over the entire lengthwise direction.

[0007]

Embodiments will be described below based on the illustrated embodiments.
Reference numeral 1 denotes a main body of the gutter block of the present invention. The main body 1 has an inverted U-shaped cross section and has a required length. Side walls 2 and 2 are provided parallel to the left and right sides. A top plate portion 3 having a haunch 3a at the corner of the back surface is provided across the upper ends of the right side walls 2 and 2. A rectangular hole 4 for mounting the lid plate is formed at the center of the top plate 3 in the length direction.

The left and right side walls 2, 2 are formed on both end faces of the main body 1.
A vertical groove 5 and a horizontal groove 6 are provided in each part. Flute 5
Has a trapezoidal cross section, and opens from the lower end surfaces of the left and right side walls 2 and 2 to the upper surface of the top plate portion 3 through the widthwise central portions thereof. Further, the lateral groove 6 is provided at the central portion in the height direction of the top plate portion 3 so as to extend outward from the respective inner portions of the vertical grooves 5 and 5 so as to intersect the vertical grooves 5 and 5 in a cross shape. is there.

The side edge in the longitudinal direction of the hole portion 4 for mounting the lid plate is left,
The right side walls 2 and 2 are cut out to the middle portion in the width direction, and the lid plate mounting step 2 is formed by the top plate 3 and the left and the upper ends of the right side walls 2 and 2.
a is formed. Further, in the central portion in the length direction of the hole portion 4 for mounting the lid plate, from the left and right side walls 2 and 2, the upper end step portion 2a,
The haunches 7, 7 having a triangular cross section for mounting the lid plates are projected to the required length inwardly along 2a.

3 and 4 show a second embodiment. In this embodiment, the haunches 3a provided at the corners of the back surface of the top plate 3 are extended to the cover plate mounting holes 4, and the cover plate mounting holes 4 are left all over the length direction. , Right wall 2,
2 has a structure in which haunches 9, 9 for mounting a lid plate, each having a triangular cross section, are projected inwardly along the upper end step portions 2a, 2a.

When installing the gutter block of the present invention, a crushed stone A is laid on the bottom of the previously excavated groove, and further discarded concrete B is placed to install the main body 1. When installing the adjacent side groove block main body 1 ', the mortar C is placed inside the vertical groove 5 and the horizontal groove 6 provided on the end face.
Is injected to connect the gutter block main bodies 1 and 1 ′ to each other.

Further, the cover plate 8 is fitted into the cover plate mounting hole 4, and the cover plate 8 is mounted on the left and right side walls 2 and 2 of the cover plate mounting steps 2a, 2a and the cover plate mounting. Support on the haunch 7 (9) for use.

[0013]

As described above, according to the present invention, in the end face portion of the main body, not only the vertical grooves in the left and right side wall portions but also the horizontal groove in the top plate portion are provided, so that the adjacent gutter block is upward due to uneven sinking. , There is no fear of slipping down.

Further, since the cover plate mounting haunch is projected inward from the left and right side walls in the cover plate mounting hole,
The lid plate has sufficient strength even when subjected to a load such as a vehicle due to the stepped portions at the upper ends of the left and right walls and this haunch, and is securely supported without causing rattling.
