Claims

[Claims for Utility Model Registration] A bolt hole 2 is provided at one end of the connecting plate 1, and a bolt groove 3 is provided along the vertical direction at the other end, and this bolt groove 3 is calculated from the bolt hole 2. The length becomes gradually shorter from the lower end to the upper end, and a driving piece 4 is provided protruding near the bolt groove 3.
After each connecting bolt 5 inserted into the bolt hole 2 and bolt groove 3 is lightly screwed into an embedded nut 6 embedded near the end face of the adjacent concrete product C,
In a connecting device configured to pull and connect adjacent concrete products C by hitting a pouring piece 4 from above, the shape of the pouring piece 4 is L-shaped and corresponds to the thickness of the end of the concrete product. The concrete product C is made by selecting a driving piece 4 having the specified width and thickness, fixing it to the connecting plate 1 by spot welding w, and bending the driving piece 4 when struck with a force exceeding a certain limit. A connecting device for concrete products, characterized in that it prevents damage or cracks from occurring at the ends.
