Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering and municipal road engineering, and more specifically, to a rotatable and convenient road formwork supporting device. Background Art

[0002] At present, during the construction of cement concrete roads, standardized steel side forms are used to fix the two sides and are used to build temporary formwork for the road surface. Its main function is to support the deadweight and external load of the concrete pavement during the construction process. It is removed after the concrete hardens to ensure the stability and flatness of the road surface during use.

[0003] When the roadbed is uneven, the steel side formwork will shift laterally and vertically, resulting in inaccurate elevation control during construction, thus affecting the subsequent stability and flatness.

[0004] After searching, a Chinese patent with publication number CN108203912B discloses a road side formwork adjustment and fixing device. The structure starts to pave the pavement structure layer by layer to ensure that the side of the road is on the same horizontal plane. During the implementation of this work, when there is a height difference in the road surface, the side formwork is adjusted left and right and up and down through the adjustment and fixing device in the middle of the side formwork to ensure that all the side formworks are on the same horizontal line, thereby ensuring the quality of pavement pouring. Finally, after pouring is completed, when the conditions for demolding are met, the device is dismantled and repaired according to actual requirements, and then transported to a storage warehouse for storage for next use, thereby improving construction efficiency and ensuring the quality of pavement construction.

[0005] However, when this structure is actually used, it is necessary to push the formwork and concrete apart when dismantling the formwork, which takes a long time and is time-consuming and labor-intensive. At the same time, it is easy for the corners of the road surface to fall off due to excessive pushing force, thus affecting the use effect. Utility Model Content
