The die device null which forms the junction crevice of concrete block and the said concrete block which are used for the junction construction method and the said construction method of concrete block

摘要

PURPOSE: To facilitate smoothing finish of joint recess sections of the surfaces of blocks used in the case blocks are connected to each other in a state of stable construction and to reduce a joint construction cost. ;CONSTITUTION: In the case blocks 1 and 1 having insertion holes 21 opened in alignment faces 10 and extended widthwise of the blocks are connected to each other, the alignment faces 10 and 10 are contacted so as to link the insertion holes 21 and 21 to each other, and parts of the ends of tension bar members 23 freely inserted into the linked insertion holes are projected to the insides of joint recess sections 25 and 25 provided to the surfaces of blocks. The tensioning bar members 23 are tensed to fix the parts of the ends to the insides of the joint recess sections, the opening ends of the joint recess sections 25 are made to close covers by screwing in cover members 39, and the surfaces of the cover members 39 are approximately flush with the surfaces of the blocks in a state to close the covers. After that, liquid filler is injected from an injection port linked with the insertion holes 21, and the joint recess sections 25 and insertion holes 21 are densely filled with liquid filler.;COPYRIGHT: (C)1994,JPO&Japio
