Problems solved by technology

[0003] The purpose of the present invention is: the segment length that can be poured in a single time of the hanging basket of the prior art is relatively short, so that the construction of the existing hanging basket is slow, if only the length of the existing hanging basket structure is increased to meet the requirements of the hanging basket If the length of a single pouring segment increases, the rods of the hanging basket will increase a lot, and the self-weight of the hanging basket will also increase greatly, which makes the construction of the hanging basket inconvenient and increases the cost. A hanging basket structure is provided

Embodiment 1

[0039] This embodiment provides a hanging basket structure, see figure 1 , including a truss load-bearing system, a walking system, a support reaction system 6 and a thrust system 5, and the travel system, a support reaction system 6 and a thrust system 5 are all installed on the truss load-bearing system, and at least two pre-loaded Stress cables 1, all the prestress cables 1 are distributed along the transverse interval of the truss load-bearing system, one end of the prestressed cables 1 is connected to the top of the longitudinal rear half of the truss load-bearing system, and the other end is connected to the truss load-bearing system The bottom of the vertical front end.

[0040] The hanging basket structure described in this embodiment, the longitudinal rear half of the truss load-bearing system is used for hanging on the construction section, the longitudinal front half of the truss load-bearing system is used for construction, and the second half is used as the load-b...

Embodiment 2

[0045] This embodiment provides a kind of hanging basket structure, and this hanging basket structure can construct the arch rib 3 sections of double arch rib at the same time, as Figure 1-7 As shown, it includes a truss load-bearing system, a walking system, a supporting reaction force system 6 and a thrust system 5, and the walking system, a supporting reaction force system 6 and a thrust system 5 are installed on the truss load-bearing system.

[0046] Such as Figure 1-5 As shown, the truss load-bearing system includes a main truss 21 and cantilevered corbels 22 arranged laterally on both sides of the lower part of the main truss 21, and the upper part of the main truss 21 is used to be placed between two arch ribs 3; The truss load-bearing system composed of the main truss 21 and the cantilevered corbels 22 arranged laterally on both sides, the upper part of the main truss 21 is used to be placed between the two arch ribs 3, forming a cantilever to the lower lateral side...

Abstract

The invention relates to a hanging basket structure which comprises a truss bearing system, a walking system, a reaction force bearing system and a thrust system, the walking system, the reaction force bearing system and the thrust system are all installed on the truss bearing system, the hanging basket structure further comprises at least two prestressed cables, and all the prestressed cables are distributed at intervals in the transverse direction of the truss bearing system. One end of the prestressed cable is connected with the top of the longitudinal rear half part of the truss bearing system, and the other end of the prestressed cable is connected with the bottom of the longitudinal front end of the truss bearing system. At least two prestressed cables are arranged between the longitudinal rear half part and the longitudinal front end of the truss bearing system, so that the longitudinal front end of the hanging basket can be pulled up by taking the top of the longitudinal rear half part of the truss bearing system as a fulcrum, the use balance of the hanging basket structure can be improved, the longitudinal length of the hanging basket structure is increased, and the service life of the hanging basket structure is prolonged. The dead weight of the hanging basket structure is reduced as much as possible, so that the hanging basket structure is convenient to construct, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of bridge hanging basket cantilever construction, in particular to a hanging basket structure. Background technique [0002] In the construction process of cantilever pouring construction arch bridges that have been built at home and abroad, the hanging baskets used are generally in the form of hydraulic portal frames, triangular trusses, side truss triangles, inverted triangle trusses, etc. Moreover, the section length of the above-mentioned hanging basket that can be poured in a single time is generally about 5m, and the longest can reach 7.3m, but it is still relatively short, resulting in many cantilever pouring sections of the long-span arch bridge, and the cantilever construction time is long. And for poor terrain (such as: canyon area, slopes on both sides, etc.), bad climate control (such as: winter time lasts for 5 months, the lowest temperature is -26.3 ℃, the maximum annual snowfall is 360cm, and ...
