[0002] During the bridge construction process, formwork support operations are required. By forming a form cavity through formwork support, concrete can be poured into the form cavity. After the concrete solidifies, the formwork support is removed. However, the existing formwork support structure is inconvenient to remove, and it is easy to damage the formwork during the removal process, affecting its secondary use. Summary of the Utility Model

[0003] In order to overcome the above deficiencies, the utility model provides a formwork support structure for pier pouring, which is convenient for disassembly and assembly, not easy to damage the formwork during the removal process, and has a long service life.

[0004] In order to solve the above technical problems, the utility model adopts the following technical scheme: A formwork support structure for pier pouring, including a formwork and a mounting seat. A movable formwork frame is installed on the mounting seat, the formwork is installed on the formwork frame, and a driving mechanism is installed between the mounting seat and the formwork frame. The driving mechanism drives the formwork frame to move reciprocally.

[0005] During the formwork support operation for the pier, the formwork is installed on the formwork frame, and then the driving mechanism drives the formwork frame to move, moving the formwork to a suitable position to complete the formwork support process. After the concrete is poured and solidified, the driving mechanism drives the formwork frame to move in the reverse direction, so as to disassemble the formwork from the solidified concrete. It is not easy to damage the formwork during the disassembly process. During the pier pouring process, the formwork support and disassembly operations are convenient, and it is not easy to damage the formwork during the formwork removal process, which is beneficial for secondary utilization and prolongs the service life of the formwork.

[0006] Preferably, the formwork frame includes a backing strip and a cross beam. The formwork is connected to the backing strip, and a diagonal brace is connected between the backing strip and the cross beam.

[0007] The backing strip, cross beam, and diagonal brace are connected together to form a triangular structure, which is stable and reliable.

[0008] Preferably, support wheels and guide wheels are arranged on the cross beam, and a guide groove is arranged on the mounting seat. The support wheels support on the mounting seat, and the guide wheels are arranged in the guide groove.

[0009] During the movement of the formwork frame, the support wheels roll on the mounting seat, and the guide wheels slide in the guide groove, which is stable and reliable. The support wheels play a good supporting role for the entire formwork frame, and the guide wheels play a guiding role to prevent the formwork frame from shifting during the movement. Moreover, the guide wheels slide horizontally in the guide groove and are longitudinally limited to prevent the entire formwork frame from longitudinally detaching from the mounting seat.

[0010] Preferably, a connecting fastener is provided between the template and the die carrier. The fastener includes a clamping seat and a claw.
