Hanging basket structure used in construction of reinforced concrete arch bridge

Abstract

The invention discloses a hanging basket structure used in construction of a reinforced concrete arch bridge. The hanging basket structure comprises a main truss load bearing system, each of the left and right sides of the middle of the main truss load bearing system is provided with a pair of C-shaped hooks, walking devices are connected with the tops of the C-shaped hooks, the bottoms of the walking devices are located on a walking track at the top of an arch box, connecting plates are arranged on the C-shaped hooks, each of the left and right sides of the connecting plates are connected with pulling seats on the side faces of the front basket and the rear basket of the main truss load bearing system correspondingly through a plurality of cable-stayed lifting strips, an anti-roller device is arranged on the rear basket, and a lifting load-bearing screw is arranged on the main truss load bearing system. When the hanging basket structure is used, great falling in the concrete pouring process can be avoided, the angle adjustment structure of the hanging basket is relatively simple, use is convenient, and a retreat mechanism cannot affect the structure of the bridge.

Description

technical field [0001] The invention relates to a hanging basket structure, in particular to a hanging basket structure used in the construction of a reinforced concrete arch bridge. Background technique [0002] Since the cantilever pouring method was used in the construction of arch bridges, the structure of cantilevered hanging baskets has successively appeared in the form of positive triangular rod hanging baskets and inverted triangular rod hanging baskets. Both of these two hanging baskets have achieved success in use. However, with the increase of the length and weight of cantilever pouring, the above two kinds of hanging baskets also have corresponding disadvantages, such as excessive stress on the rods, excessive deflection at the end of the cantilever, etc., making the existing hanging basket form unable to meet the requirements of cantilever pouring requirements. [0003] After a section of hanging basket is poured, it is necessary to move the hanging basket forw...

Problems solved by technology

However, there is a problem with this method, that is, the size of the opening is large, the main reinforcement avoids the opening when reserved, and the post-filling concrete at the opening position cannot be completely combined with the original structure, which causes the stressed structure of the arch ring to fail to match the original design. , affecting the performance of the bridge

[0004] Furthermore, the existing hanging basket structure does not have an effective anti-deflection structure during the forward movement process, resulting in the situation that the axis of the hanging basket is not parallel to the axis of the arch ring when the hanging basket moves forward, resulting in lateral deviation of the hanging basket. However, the bridge needs to be constructed according to the design drawings, so that the lateral offset of the hanging basket needs to be corrected after it is moved forward, which is time-consuming and laborious
