Description

TECHNICAL FIELD

[0001] The application relates to the technical field of concrete pavement construction, in particular to a rapid adjustable pavement support device. BACKGROUND

[0002] In the process of concrete pavement construction, a support formwork needs to be stably installed along the edge line surface of the concrete pavement for stable setting treatment of the poured concrete pavement, so that the concrete can be solidified under the setting structure. Generally, construction personnel use steel bars to resist the formwork and insert the ground for installation, so as to position the support formwork. However, after pouring concrete, the formwork support structure is unstable, which may cause the formwork to expand and run, resulting in unqualified concrete quality and waste of concrete.

[0003] The existing public technology number CN221523240U proposes an adjustable device for concrete pavement formwork support. The device can be used in various complex geological and topographical conditions for formwork support during concrete pavement construction, ensuring the construction quality of the concrete pavement and improving the construction efficiency. It can prevent the formwork from tilting outward and inward, and a plurality of buckles B are configured to be used in different complex conditions. The two sleeves in the buckle B are adjusted to different angles to cope with various complex geological and topographical conditions, effectively fix the formwork support device, prevent the formwork from running and expanding, ensure the construction quality, and solve the technical problems of the related technology in the background. However, the structure of the pavement support device in the comparative document is relatively complex, the construction installation is not convenient, the support structure is located on the upper part of the concrete pavement, and the adjustment is not convenient, which affects the construction process. Therefore, we propose a rapid adjustable pavement support device. CONTENT OF THE UTILITY MODEL
