FIGS. 1 to 4 show a first embodiment in which the present invention is applied to a pedestrian road boundary block 1. The pedestrian road boundary block 1 comprises a set of a concrete block main part 3, a rubber molding 5, three bolts 7, one joint piece 9, and the like.

The block main part 3 has a length of about 1 meter, and has a non-equilateral trapezoidal shape as viewed from the longitudinal direction. In other words, the side surface 11 facing the sidewalk is vertical, but the side surface 13 facing the roadway is a slope inclined so as to move away from the side surface 11 facing the sidewalk as going down. The block main part 3 is provided with three screw holes 17 opened in the upper surface 15 in all of the intermediate part and the positions near both ends in the longitudinal direction. This screw hole 17
It is provided by embedding a tube 19 having a thread formed on the inner peripheral surface. The tube 19 may be made of metal or synthetic resin, and in some cases, a pilot hole may be provided directly without using a tube.

The molding 5 has the same length as the length of the block main part 3 in the longitudinal direction, and the shape viewed from this direction is substantially L-shaped. That is, the mall 5 includes the horizontal portion 21
And a side portion 23 protruding downward from one side thereof is integrally formed. The width of the bottom surface of the horizontal portion 21 is the same as the width of the upper surface 15 of the block main portion 3. Reference numeral 23 has a length substantially equal to the width of the horizontal portion 21. The side surface 23a of the side portion 23 on the horizontal portion 21 side is a slope having the same gradient as the gradient of the side surface 13 of the block main portion 3, and the upper and lower corner portions of another side surface 23b are arcuate surfaces. . The horizontal part 21 and the side parts 23 have a thickness of about 50 mm.

The horizontal portion 21 is formed with three bolt through holes 25 arranged in the longitudinal direction, and the upper half of the bolt through hole 25 is formed to have a larger diameter than the lower half. , A shoulder 25a in the middle. The bolt 7 is passed through the bolt hole 25. The arrangement interval of the three bolt through holes 25 matches the arrangement interval of the three screw holes 17 provided in the block main part 3.

Such a molding 5 is formed of a rubber material such as synthetic rubber. Specifically, a rubber chip, for example, a chip of a so-called old tire crushed to about several millimeters, is put in a mold and heated at 150 ° C. for about 1 hour while being pressed at about 120 tons to be molded.

The results (average value) of the strength test performed on the molding 5 prototyped by the present inventors are shown below. (The test method is shown in parentheses.)-Tensile strength: 17.3 kgf / cm2 [J
IS K6301 (20 ° C)].・ Elongation rate: 116% [JIS K6301 (2
