Therefore, a buffer device is provided to prevent the bridge formwork from cracking and affecting the service life and structural stability. Moreover, expansion joint construction will be carried out between the bridge formworks before and after construction. Therefore, a quick connection device that can have the effect of expansion joint construction while connecting the bridge is provided to improve the overall construction efficiency.

[0019] The principles and features of the present utility model will be described below with reference to the drawings. The examples given are only used to explain the present utility model and are not intended to limit the scope of the present utility model.

[0020] Example 1

[0021] As Figures 1 to 4As shown in the figure, a quick connection device for modular bridge formwork includes: a plurality of bridge formworks 1 arranged in sequence. Two mutually engaging telescopic toothed plates 4 are arranged in the gap between two adjacent bridge formworks 1. The telescopic toothed plates 4 are made of steel plates. A plurality of cover plates 3 are fixed at the non-toothed surface ends of each telescopic toothed plate 4. In addition, a connecting plate 7 is arranged below each bridge formwork 1. Through holes 5 are opened on each bridge formwork 1 corresponding to the cover plates 3 on it (this bridge formwork 1) and the connecting plate 7 below it (this bridge formwork 1). Since there are multiple cover plates 3, the number of through holes 5 opened on each bridge formwork 1 is also multiple. A threaded cylinder 6 is arranged in each through hole 5. The lower end of the threaded cylinder 6 is fixedly connected to the connecting plate 7 below it (this threaded cylinder 6). The fixed connection method can be welding. A first bolt 8 is arranged above the cover plate 3, and the rod end of the first bolt 8 passes through the cover plate 3 below it (this first bolt 8) and is threadedly connected to the threaded cylinder 6 to complete the fixation of the connecting plate 7, the cover plate 3, and the telescopic toothed plate 4, and the assembly is very convenient;

[0022] One of the two adjacent connecting plates 7 opens a sliding groove 10 on the adjacent side, while the other connecting plate 7 fixes a sliding block 9 on the adjacent side. The sliding block 9 extends into the sliding groove 10. The connecting plate 7 opens travel grooves 14 communicating with the sliding groove 10 on two side surfaces along the width direction of the sliding groove 10. A limiting block 11 fixed to the sliding block 9 is arranged in the travel groove 14. The length of the limiting block 11 is less than the length of the travel groove 14. When the bridge formwork 1 shakes, the sliding block 9 can shake in the gap left inside the sliding groove 10.
