Title:
CONCRETE BLOCK FOR SLOPED FORM
Document Type and Number:
Japanese Patent JP2769967
Kind Code:
B2
Abstract:

PURPOSE: To improve lightening, transportability and handling properties by hollowing the insides of the crosses sides of a concrete block for sloped forms and containing a light-weight foam in the inside.
CONSTITUTION: The insides of the crossed sides of a concrete block 1 are hollowed. Light-weight foams 4 are contained in the insides. Haunches having 70% size or more of crossed side width are formed at each corner section of a block intersection. The ratio Ac/A of an intersection-section pressure- receiving area Ac to the pressure-receiving area A of the whole block is set in 0.25≤Ac/A≤0.55. The concrete blocks 1 are adjoined so that one sides are formed in a row along the direction L. The concrete blocks 1 are also adjoined in a row in the height direction tying the face of a slope 2 and the toe of the slope 3. Accordingly, the concrete blocks l are lightened, and transportability and handling properties are improved while cost can be reduced.
