Building blocks and mortar inflow prevention tool of the building blocks

摘要

PPROBLEM TO BE SOLVED: To provide a mortar inflow preventing implement for a building block preventing mortar from falling and flowing into a vertical reinforcement insertion hole not requiring the insertion of a vertical reinforcement, and to provide the building block. PSOLUTION: The mortar inflow preventing implement is a blocking implement for the vertical reinforcement insertion hole 4 or 5 not requiring the insertion of the vertical reinforcement 7 in the building block 2 having a horizontal reinforcement insertion groove 3 and the vertical reinforcement insertion holes 4, 5. The mortar inflow preventing implement is formed of a flexible, hard or semihard flexible plastic or metal sheet and fitted in close contact into the horizontal reinforcement insertion groove 3 to block the vertical reinforcement insertion hole 4 or 5 not requiring the insertion of the vertical reinforcement 7. The building block uses the mortar inflow preventing implement to block the vertical reinforcement insertion hole 4 or 5 not requiring the insertion of the vertical reinforcement 7.
