Title:
ブロック及びコンクリート構造物
Document Type and Number:
Japanese Patent JP6786809
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide blocks for efficiently constructing a rigid concrete construction, and the concrete construction using the same.SOLUTION: Blocks 10 are columnar precast concrete having square base shape bottom surfaces, and have center penetration holes 12 and notches 15, 16 formed at opposing sides having magnitudes of halved sizes. Center points of the notches 15, 16 are arranged on linear lines L1 passing center points of the center penetration holes 12 at an equal interval. By planarly filling the blocks 10, synthetic penetration holes are formed of the notches 15, 16 of the adjacent blocks 10. When laminating the blocks 10, the blocks 10 are arranged so as to be displaced from one another so that positions of the center penetration holes 12 of the block 10 at a lower layer and positions of the synthetic penetration holes at an upper layer coincide with each other, and positions of the synthetic penetration holes at the lower layer and positions of the center penetration holes 12 of the block 10 at the upper layer coincide with each other. By the lamination, reinforced concrete is formed in a cylinder space which is formed of the synthetic penetration holes and the center penetration holes 12 of the blocks 10.SELECTED DRAWING: Figure 1
