Description

Technical Field

[0001] The utility model relates to the field of road and bridge construction, in particular to a formwork support device for road and bridge construction. Background Art

[0002] The existing patent (publication number: CN218842896U) proposes a formwork support device for road and bridge construction, including a support plate, a support rod and an adjustment plate. On both sides near the upper part of the rear surface of the support plate, a first positioning block is fixedly installed. On both sides near the lower part of the rear surface of the support plate, a second positioning block is fixedly installed. The support rod is movably installed inside the first positioning block. The adjustment plate is movably installed inside the second positioning block. A positioning member is horizontally inserted through the adjustment plate. Sliding sleeves are movably installed on both sides of the lower end surface of the support rod. However, in this device, the supporting area of the "support plate" is limited. Therefore, when supporting the formwork for road and bridge construction, multiple groups of support plates need to be joined and connected. Due to the lack of a locking device at the edge of the support plate, there are likely to be splicing gaps or misalignments between adjacent support plates, thus affecting the stability of its supporting force. If fixed with nails, the operation efficiency is low, and it will cause damage to the edge of the support plate after removal, affecting the reuse of the support plate, which has drawbacks. Summary of the Invention

[0003] In view of the above deficiencies in the prior art, the utility model provides a formwork support device for road and bridge construction, which has stable support, improves the concrete forming effect and the quality of road and bridge construction. It can correspondingly increase or decrease the number of support plates according to the actual size of the formwork for road and bridge construction. Through the joining and connection of multiple groups of support plates, it can meet the support requirements of formworks of different lengths. Moreover, the support plates are closely joined, the disassembly and assembly operations are convenient, and it will not cause damage to the edge of the support plate after disassembly, and does not affect the reuse of the support plate.
