«Configuration example»
(1) First, an example of a gutter block on which the gutter lid is installed will be described with reference to FIG. Reference numeral 10 in FIG. 1 denotes a gutter block. The side groove block 10 is formed in a U-shape in a longitudinal cross section, and includes side walls 12 erected on both side ends of the bottom wall 11 and receiving portions 13 formed on top of the respective side walls 12. There is an opening W between the upper ends of the two. Further, each receiving portion 13 is formed so as to protrude in a rectangular shape from the inner surface of the side wall 12, and has a horizontal surface 13a on which the side gutter is placed.

  (2) Next, an example of the side groove cover will be described with reference to FIG. Reference numeral 20 in FIG. 2 denotes the gutter lid installed in the gutter block 10. The gutter 20 closes the opening W of the gutter block 10.

  Specifically, the side groove cover 20 includes a concrete lid body 21 formed in a substantially rectangular flat plate shape, a row of stoppers 23 formed parallel to the bottom surface 21 a of the lid body 21, and stoppers 23 at the bottom surface 21 a. And five projections 22 formed at equal intervals on the outside of each row. An uneven pattern is formed on the flat surface 21 b of the lid body 21, and notches 24 are formed on the front and rear end portions of the lid body 21.

  Here, each stopper 23 is formed to be vertically long (length = L4), and a row of the stoppers 23 is configured by arranging three stoppers 23 in series at an interval L1 along the longitudinal direction of the bottom surface 21a. There is.

  The interval L1 is set to a ratio of “L1: L4 = 1: 8 to 1:15”, and “L1: L5 = 1: 30 to 1” with respect to the length “L5” of the lid main body 21 in the longitudinal direction. It is set at a very slight distance of 50:50. Further, the distance L2 between the outer surfaces 23a of the stoppers 23 of each row is formed to be substantially equal to the distance L3 between the two receiving portions 13 of the side groove block 10.

  Further, each protrusion 22 is formed in a semicircular shape in a longitudinal cross section, and is disposed corresponding to each stopper 23. That is, on the bottom surface 21 a, two protrusions 22 are formed on the outer side of the front and rear stoppers 23, and one protrusion 22 is formed on the outer side of the central stopper 23.

«Installation example»
An example of installation of the gutter 20 on the side gutter at the corner of the road will be described based on FIG. Here, it is assumed that the embedding of the gutter block is completed in advance at the corner R of the gutter. The side groove block 10 embedded in the corner portion R is subjected to processing such as cutting according to the curvature and the length of the corner portion R. The side groove cover 20 is installed in the side groove block 10 subjected to processing such as cutting, and the opening W is closed by the side groove cover 20.

  Here, the side groove cover 20 is cut similarly to the side groove block 10 in accordance with the curvature and the length of the corner portion R. The cut side groove cover 20 is referred to as a divided portion, and the divided portion 20 (R2-1 to R5-1, R2-2 to R5-2) cut obliquely to construct the corner portion R, and the length Adjustment division parts 20 (R1-1, R1-2) are used.

  For example, the dividing portion 20 (R2-1) is obliquely cut so as to divide the side groove lid 20 into a rectangular shape along the PP broken line in FIG. 3C. Similarly, the other divisions 20 (R3-1 to R5-1 and R2-2 to R5-2) are also cut obliquely by changing the cutting angle and the cutting position.

  Further, the dividing portion 20 (R1-1) is cut so as to divide the side groove cover 20 into a substantially square shape along the Q-Q broken line in FIG. 3 (d). Similarly, the other divisions 20 (R2-2) are divided by changing the cutting position. In addition, the division part 20 by the side of (beta) shall be used in the position of R1-1 and R2-1.

  When installing the dividing portion 20 in the gutter block 10, the dividing portions 20 (R2-1 to R5-1, R2-2 to R5-2, R1-1, R1-2) It installs sequentially on both the receiving parts of the gutter block 10 of a corresponding position.

  At this time, although the stoppers 23 are cut at the time of cutting the gutter 20, the respective stoppers 23 of the gutter 20 are arranged in series on the bottom surface 21a with an interval L1, so the four corners of the bottom surface 21a of the divided portion A stopper 23 (including a portion of the cut stopper 23) is disposed.

  Therefore, as shown in FIG. 3B, the respective stoppers 23 of the divided portions (R2-1 to R5-1, R2-2 to R5-2, R1-1, R1-2) respectively correspond to the corresponding side groove blocks. Located between the two receiving portions 13 of 10. As a result, each stopper 23 is locked to the receiving portion 13, and positional deviation of the divided portion 20 and the like are suppressed.

  Here, in the patent document 3, the arc-shaped protrusion 16 (the same symbol) is inserted into the V-shaped gap 18 (the symbol in the patent document 2) to suppress the displacement in the width direction. Also, since the shape of the ridges 16 or the gap 18 is required, it can not be used for a general-purpose gutter block lid, and the versatility is low.

  On the other hand, according to the gutter 20, no special structure such as the ridges 16 and the gap 18 is necessary on the gutter block 10 side, and the misregistration suppression is achieved only by using the gutter 20 as a lid of the existing gutter block 10. The effect of In this respect, the gutter 20 is highly versatile, and its shape and effect are significantly different from those of Patent Document 3.

  In addition, while two protrusions 22 of the side groove lid 20 are formed on the outside of the front and rear stoppers 23, one protrusion 22 is formed on the outside of the central stopper 23. According to this arrangement configuration, the protrusions 22 are disposed at four corners of the bottom surface 21 a of at least the divisions 20 (R2-1 to R5-1, R2-2 to R5-2, R1-1, and R1-2). .

  Therefore, the stoppers 23 of the divided portions 20 (R2-1 to R5-1, R2-2 to R5-2, R1-1, and R1-2) are on the horizontal surface 13a of the receiving portion 13 of the corresponding groove block 10 respectively. Placed on

  As a result, rattling and the like of the divisions 20 (R2-1 to R5-1, R2-2 to R5-2, R1-1, and R1-2) are suppressed. As a result, according to the gutter 20, the gutter block embedded in the corner portion R can be installed without causing positional deviation or rattling.
