Claims

[Claims for Utility Model Registration] 1. A joining piece embedding hole 2 is provided at a predetermined portion on at least both sides of one end joining surface 1a of the block main body 1, and the joining piece embedding hole 2 matches the shape of the one end joining surface 1a and corresponds to the embedding hole 2. An expansion joint member 4 having a piece insertion hole 5 is superimposed on the one end joining surface 1a, and the base half 6 of the joining piece 6 is
a into the piece embedding hole 2 through the piece insertion hole 5,
On the other hand, a drop hole 8 is formed in the other end joint surface 7b of another block main body 7 to be joined to this, which has a downwardly tapered shape into which the protruding half 6b of the joining piece 6 is fitted, and whose bottom part tightly fits into the joining piece 6. The concrete is characterized in that the protruding half 6b of the joining piece 6 is fitted into the drop-in hole 8, and the blank space of the drop-in hole 8 is filled with mortar 10 to align the joining surfaces. Joint structure of block expansion joints. 2. The joining structure for expansion joints of concrete blocks as set forth in claim 1 of the registered utility model claim, in which the joining pieces 6 are formed in a tapered shape from the center back and forth. 3. Utility model registration claim 1, which is constructed so that the sum of the depth of the joint piece embedding hole 2 and the thickness of the expansion joint member 4 is equal to the length of the base half 6a of the joint piece 6.
A joining structure of expansion joints of concrete blocks according to item 1 or 2. 4. Joining of expansion joints of concrete blocks according to any one of claims 1 to 3 of claims 1 to 3, which are obtained by integrally polymerizing the expansion joint member 4 during the molding and curing stage of the block body 1. structure. 5 Expansion joint of a concrete block according to any one of claims 1 to 3 of claims 1 to 3, which is obtained by polymerizing an expansion joint member 4 to one end joint surface 1a of the block body 1 via an adhesive. Joint structure of parts.
