Problems solved by technology

[0007] However, in the case of the block of Patent Document 1, there is a problem that when the subsequent block 51 advances toward the last block 52 during laying, the bottom surface 71 of the block 51 is placed between the sand cushion 42. Sliding on the surface, therefore, the pad sand on the surface side of the sand cushion layer 42 is dragged, causing the flat surface state of the sand cushion layer 42 to become rough
[0008] In addition, there is a problem that, after laying, an unexpected load is applied from above to the joints of the blocks 51 to 53 adjacent to each other in which the convex strip 61 and the concave strip 62 are fitted together. , the arc-shaped curved surfaces of the cross-section, that is, the convex strip 61 and the concave strip 62 slide relative to each other in the direction along the curved surface, and the other block is misplaced relative to one block, so the flatness of the joint cannot be ensured.

no. 1 Embodiment approach ）

[0044] Below, refer to Figure 1 to Figure 6 A first embodiment in which the present invention is embodied as paving blocks laid on sidewalks, public places, etc. will be described.

[0045] Such as figure 1 and figure 2 As shown, the block 11 of this embodiment has the block main body 12 formed in the shape of a flat plate, and this block main body 12 is comprised with concrete, and has a quadrangular shape in front view. A convex portion 17 is formed on the front side (one side) 13 of the four sides 13 , 14 , 15 , 16 of the rectangular laterally longer sides of the block main body 12 , and on the rear side opposite to the front side 13 The (other side) 15 is formed with a concave portion 18 having a shape corresponding to the convex portion 17 , that is, capable of fitting with the convex portion 17 formed on the front side 13 of another block 11 .

[0046] In addition, the convex portion 17 and the concave portion 18 extend along the lengthwise direction of the respect...

no. 2 Embodiment approach ）

[0075] Next, refer to Figure 7 A second embodiment of the present invention will be described. In addition, compared with the first embodiment, the partial structures of the convex portion 17 and the concave portion 18 in other embodiments including the second embodiment to the sixth embodiment described below are different, but the other points are 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 identical structures, and repeated description will be omitted.

[0076] Additionally, if Figure 7 As shown, in the block 11 of the second embodiment, the convex underside contour portion 17c of the convex portion 17 formed on the front side 13 and the concave portion underside contour portion 18c of the concave portion 18 formed on the rear side 15 are located in the front and rear. It is dif...

no. 3 Embodiment approach ）

[0080] Next, refer to Figure 8 A third embodiment of the present invention will be described.

[0081] Additionally, if 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 It differs from the configuration of the first embodiment in which these portions are formed in an oblique planar shape in that the front-rear direction is formed in a convexly curved shape inclined forward and downward. 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.

[0082] Therefore, also in this third embodiment, the same effe...

Abstract

A building block has good workability when being paved on flat sand cushion layer, and can maintain planarity of gap between adjacent blocks after paving. When the bottom surface of the block is downward, a convex portion is formed on the front side, a concave portion with a shape corresponding to the concave portion is formed on the back side, and a cross-section shape is formed by cutting along the direction of protruding direction of the convex portion and the deboss direction of the concave portion. A forward downward inclined shape is formed from the top of the convex portion to the bottom of the concave portion. In the protruding direction of the convex portion and the deboss direction of the concave portion, a non-forward upward inclined shape is formed from the top of the convex portion to the bottom of the concave portion.

Description

technical field [0001] The present invention relates to a pavement block laid on, for example, sidewalks, public places and the like. Background technique [0002] Conventionally, as such a block, the block described in patent document 1 is known, for example. In this block, on one side of a block body forming a flat plate shape, a convex line extending along the entire length of the side in the longitudinal direction is formed, and a concave is formed on the other side opposite to the one side. When laying blocks, the concave strips are fitted with the above-mentioned convex strips formed on other adjacent blocks. These convex lines and concave lines are formed so that the cross-sectional shape of the part which fits mutually forms an arc shape of substantially the same size. [0003] In such previous blocks, such as Figure 17 As shown, on the sand cushion (sand cushion) layer 42 composed of cushion sand spread on the roadbed 41, the adjacent blocks are laid sequentially...
