A kind of combination type prestressed long sleeper composable mold of concrete, it is characterised in that slide device includes bottom
Plate, sliding panel and several axis of rolling, bottom plate are equipped with several semi-circular rolling grooves, and the axis of rolling is placed in rolling groove and rolls
Moving axis diameter is greater than the radius of rolling groove, and the both ends of rolling groove have raised platforms, and sliding panel is in groove-like, the both ends of sliding panel
Mutually it is connected with raised platforms and is placed on the axis of rolling.
Using the present invention, it can according to need the shoulder block type and the long sleeper of non-shoulder type of production, it is total to provide different shells
At, when putting any end stress can be transferred through returning device and slide device be allowed to stress equalization after playback naturally, reduce pre-
Stress damage avoids the occurrence of shoulder, broken angle phenomenon, thus both can a general frame produce any model shoulder block type and
The long sleeper of non-shoulder type, and product quality can be improved, production cost can be greatly reduced.
