Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a hanging basket leveling device for concrete cantilever construction. Background Art

[0002] The hanging basket is a load-bearing frame that can slide or roll along the top of the beam. The hanging basket is anchored and suspended on the constructed beam section to provide an aerial platform for the next stage of construction. After completing the construction of one segment, the hanging basket can be moved forward and fixed to carry out the construction of the next segment, and this cycle will continue until the cantilever pouring is completed. In the existing hanging basket hanging pouring technology, the installation quality of the hanging basket is the key to affecting the pouring quality and construction safety, especially the flatness of the hanging basket track, which has a direct impact on the stability of the main truss and the uniform force on the main truss. Under the influence of factors such as the transverse slope and longitudinal slope of the bridge, the distance between the main truss of the hanging basket track and the ground usually changes within a certain range, so the track needs to be leveled. Currently common track leveling methods include high-strength mortar leveling method and steel beam leveling method.

[0003] In the existing technology, a cantilever cast-in-place hanging basket track leveling device and a leveling method thereof are proposed with the publication number: CN113931082A. The leveling device includes a plurality of leveling units arranged along the length direction of the hanging basket track, and the leveling unit includes a support part and an adjustment part; the support part includes a lower steel plate arranged on the ground, and a plurality of high-strength studs are arranged on the lower steel plate. The top of the high-strength studs penetrates the upper steel plate, and a leveling nut is arranged on the high-strength studs on the lower surface of the upper steel plate; a piston-type sand box is used to change the traditional process, overcome the problem of inconsistent heights of the main truss tracks caused by the longitudinal and transverse slopes of the bridge, and improve the stability of the hanging basket track. It can solve the problems of low leveling efficiency of the traditional process, the inability to ensure the strength of the leveling structure, and the inability to accurately level. At the same time, the present invention has the characteristics of high stability, reusability, energy saving and environmental protection, and convenient storage, with obvious economic benefits and certain application and promotion value.

[0004] In order to solve the problem in the existing hanging basket suspended casting technology that the installation quality of the hanging basket is the key to affecting the casting quality and construction safety, especially the flatness of the hanging basket track, which has a direct impact on the stability of the main truss and the uniform force of the main truss, the existing technology uses a piston-type sand box to adjust multiple leveling nuts. However, there is still a problem that each leveling nut needs to be adjusted separately according to the height of the piston-type sand box below it, which makes the adjustment process cumbersome and repetitive, increases the time required for leveling, and further leads to a problem of reduced utilization efficiency of the leveling device.
