Embodiment Construction

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] Such as Figure 1-8 , the cable tower 1 of the present embodiment includes four sides, which is a prism structure with a small upper part and a larger lower part. The set of load-bearing frames 4, since the side of the cable tower 1 gradually narrows from bottom to top, the distance between the tracks of the two groups of load-bearing frames 4 located on the outside of the side needs to shrink to adapt to the narrowing of the sides, so when the climbing formwork body 2 travels to the cable tower 1 At a certain height, it is necessary to change the track of the bearing frame 4. The actual track change is to translate the two sets of load-bearing frames 4 on the outer side of the cable tower 1 to the middle, and the load-bearing frame 4 in the middle of the side does not need to change the track.

Abstract

The invention relates to the technical field of building construction, in particular to an aerial track-change construction method of a climbing form of a cable tower. When the climbing formwork body travels to the area where the cable tower is to be changed, a temporary support frame is installed on the outside of the cable tower, so that the weight of the climbing formwork frame is transferred from the load-bearing frame to the temporary support frame, and then from the original side of the cable tower. Remove the load-bearing frame from the track, install the dismantled load-bearing frame to the track change, transfer the weight of the climbing formwork frame to the load-bearing frame, then remove the temporary support frame, and re-insert the track change track to complete the track change construction of a single track . The track changing method of the invention is simple and safe, reduces hoisting procedures and aerial operations, greatly simplifies the process of climbing formwork changing tracks, and has popularization value.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a construction method for cable tower climbing formwork rail change in the air. Background technique [0002] Climbing formwork is a tower column construction device that uses a climbing system to automatically climb the frame and formwork to the next construction section. Including the overall frame body, the formwork is fixed on the frame body, the frame body is supported on the load-bearing frame, the load-bearing frame is anchored on the concrete that has been poured, and the climbing of the entire climbing formwork is realized through the step-by-step jacking structure. With the development of building structure technology, the pouring of the main structure is becoming more and more complex. For example, in the construction of cable towers, the height of the cable towers and the decorative strips need to be considered during the pouring process of the cable tower...
