Description

Technical Field

[0001] This utility model relates to the field of civil engineering technology, and in particular to a closed arched structure wooden formwork arc support system. Background Technology

[0002] The arched wooden formwork and arc-shaped support structure is a temporary support system used for pouring arched concrete components. It consists of arc-shaped wooden formwork and support devices. The arc-shaped wooden formwork conforms to the curve of the arch, and the support structure provides rigid fixation to ensure that the formwork does not deform or shift during pouring. It is used for the construction of arc-shaped components of arch bridges and arch tops, and has both adaptability and workability.

[0003] The closed arched wooden formwork with arc support structure is used for the construction of closed arched components that require overall load-bearing. The closed design can evenly distribute the concrete pouring pressure and avoid local deformation. The arc support fits tightly with the formwork to ensure the accuracy of the arch curve. The wooden formwork is adapted to complex curvatures, and the overall structure enhances stability. It is used for closed arched structures in tunnels and domes to ensure forming quality and construction safety.

[0004] In construction, conventional scaffolding, due to its fixed structure, is difficult to adapt to the curved shape of curved surfaces and cannot effectively provide stable support for curved parts, affecting construction quality. In existing technologies, arched structural support devices can meet the support requirements of curved surfaces by conforming to the curved surface of the building through an arc design, ensuring the stability of construction in curved parts. However, in actual use, the connection of support components is complicated, and the installation and dismantling process consumes a lot of time, reducing construction efficiency and hindering the progress of the project.
