no. 1 Embodiment approach

[0024] Below, refer to Figure 1 to Figure 6 , the first embodiment in which the present invention is embodied as paving blocks laid on, for example, sidewalks or public places will be described.

[0025] Such as figure 1 with figure 2 As shown, the block 11 of this embodiment has the block main body 12 which is formed of concrete, has a quadrangular planar view, and is formed in a flat plate shape. A convex portion 17 is formed on the front side 13 among the four side surfaces 13 , 14 , 15 , and 16 of the block main body 12 having a rectangular laterally elongated shape. A concave portion 18 is formed on the rear side 15 opposite to the front side 13 of the block main body 12, and the concave portion 18 is formed in a shape corresponding to the convex portion 17, that is, the concave portion 18 can be formed in other blocks 11. The convex part 17 on the front side 13 is fitted.

[0026] In addition, the convex portion 17 and the concave portion 18 are formed in such a m...

no. 2 Embodiment approach

[0054] Next, refer to Figure 7 , and the second embodiment of the present invention will be described. In addition, in other embodiments from the second embodiment to the sixth embodiment described below, the difference from the first embodiment lies in the local structures of the convex portion 17 and the concave portion 18, while the other structures adopt the same structure. Therefore, in the description of each of the following embodiments, components that are different from those of the first embodiment will be mainly described, and the same reference numerals will be assigned to other similar structures, and repeated description will be omitted.

[0055] Such as Figure 7 As shown, in the block 11 of the second embodiment, the convex portion lower contour portion 17c of the convex portion 17 formed on the front side 13 and the concave portion lower contour portion 18c of the concave portion 18 formed on the rear side 15 are formed as The slope shape inclined forward an...

no. 3 Embodiment approach

[0059] Next, refer to Figure 8 , and the third embodiment of the present invention will be described.

[0060] Such as Figure 8 As shown, in the block 11 of the third embodiment, the convex upper profile 17b of the convex 17 formed on the front side 13 and the concave upper profile 18b of the concave 18 formed on the rear side 15 are formed It differs from the first embodiment in which these portions are formed in an inclined planar shape in that it is a convexly curved shape inclined forward and downward in the front-rear direction. However, in the third embodiment, the convex portion upper contour portion 17b of the convex portion 17 and the concave portion upper contour portion 18b of the concave portion 18 are also formed in a shape inclined forward and downward in the front-rear direction of the longitudinal cross-sectional shape. This point is the same as that of the first embodiment.

[0061] Therefore, also in the third embodiment, the same effects as the above-me...

Abstract

The invention provides a block with a convex portion formed on the front side surface and a concave portion formed in the back side surface in a shape corresponding to that of the convex portion. A shape inclined to a front-lower direction in a front-and-back direction is formed on an upper side profile of the convex portion extending from the front end of the convex portion to a based end on the upper surface of the convex portion and on an upper side profile of the concave portion extending from the inner end of the concave portion to an opening of the concave portion on the upper surface of the concave portion, on a longitudinal section shape formed when the bottom surface of the block is disposed at the lower side and the block is cut along a vertical plane along a front-and-back direction. A shape not inclined to a front-upper direction in the front-and-back direction is formed on a lower side profile of the convex portion extending from the front end of the convex portion to the based end on the upper surface of the convex portion and on a lower side profile of the concave portion extending from the inner end of the concave portion to the opening of the concave portion on the lower surface of the concave portion, on the longitudinal section shape. According to the invention, the block which has excellent application property and can well maintain joint planarity of adjacent blocks after being laid can be obtained.

Description

technical field [0001] The present invention relates to a pavement block to be laid on, for example, sidewalks or public places. Background technique [0002] Conventionally, as such a block, the block disclosed by Unexamined-Japanese-Patent No. 2004-263370 is known, for example. In this block, a ridge extending along the entire length in the longitudinal direction of the front side surface is formed on the front side surface of the flat block main body. A concave line is formed on the rear side opposite to the front side, and when the block is laid, the concave line fits with the above-mentioned convex line formed on another adjacent block. These convex lines and concave lines are formed so that the cross-sectional shapes of the portions where they fit with each other have substantially the same arc shape. [0003] In this existing block, such as Figure 12 As shown, on the sand cushion layer (sand cushion layer) 42 formed by the cushion sand spread on the road bed 41, it...
