[0002] A road bridge generally refers to a structure erected over rivers, lakes and seas to enable vehicles, pedestrians, etc. to pass smoothly. To adapt to the modern rapidly developing transportation industry, a bridge is also extended to a building that is erected across mountain streams, poor geological conditions or to meet other traffic needs to make passage more convenient. A bridge generally consists of an upper structure, a lower structure, bearings and auxiliary structures.

[0003] In the prior art, when reinforcing the formwork of a road bridge at the top of a pier, the length of the support is fixed and cannot achieve the reinforcement and stability of the formwork of the road bridge, resulting in the inclination and collapse of the formwork of the road bridge when pouring concrete. Secondly, when adjusting the horizontal height on both sides of the formwork of the road bridge, it is necessary to install cushion blocks under the formwork of the road bridge for horizontal adjustment. The process is cumbersome and the position needs to be found correctly, and the operation is too cumbersome. Content of the Utility Model

[0011] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0012] 1. In the present utility model, when pouring a road bridge on the top of a bridge pier, a pouring mold template will be installed on the top of the bridge pier. Since the poured concrete has a certain weight, it is necessary to reinforce and support the mold template. At this time, the clamping grooves and clamping blocks of the two clamping pipes are clamped and sleeved on the surface of the bridge pier. After adjusting to the appropriate height, the fastening bolts are rotated to abut against the bridge pier for fixation. Then, by rotating the rotating wheel, the transmission shaft and the gear are driven to rotate, and at the same time, the moving rod is driven to move along the direction of the tooth groove and the movable groove to adjust the length, and the support plate is adjusted to support the template of the road bridge, avoiding the phenomenon that the fixed length of the support cannot achieve the reinforcement and stability of the template of the road bridge, resulting in the inclination and collapse of the template of the road bridge when pouring concrete.
