Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a joint structure for a waterway formed by connecting waterway construction blocks such as secondary concrete products.

[Prior art] As a conventional waterway joint structure, for example, the
-There is one disclosed in Publication No. 4164. In this joint structure, a nut body is embedded and fixed at the end of a waterway construction block, and with the ends of the waterway construction blocks butted against each other, a bolt passing through a small diameter hole at one end of the connecting plate is inserted into one waterway. By screwing into the nut body of the construction block, and screwing another bolt that passes through the oblong hole at the other end of the connecting plate and the eccentric shaft hole of the eccentric seat plate into the nut body of the other waterway construction block. , join adjacent waterway construction blocks on the left and right.

[Problems to be solved by the invention] However, in such a waterway joint structure,
If the threaded tightening of the bolt is weakened due to a construction error, or if the gap between the joint members is larger than the specified size due to a manufacturing error, it may be difficult to predict the situation on weak ground. When a large overload load is applied, the block rows are sometimes unable to withstand the load, causing them to bend and sink.

Furthermore, the joints in this structure cannot have very long spans, and in soft ground, the number of support piles must be increased and a pedestal must be installed for each waterway construction block, that is, for each joint. Nakatsuta.

Therefore, an object of the present invention is to apply an appropriate pressing force to each waterway construction block even if the bolts are weakly tightened or the gap between the joints exceeds a predetermined value. Since it acts between the joint ends, the block row will not bend even if the ground is weak and unexpectedly large loads are applied, and it is also necessary when applied to large and heavy blocks for building waterways. It is an object of the present invention to provide a waterway joint structure that can accurately obtain sufficient pressing restraining force and can sufficiently lengthen the installation span of support piles and pedestals.
