Problems solved by technology

[0003]Conventional system conversion is usually to manually cooperate with the tower crane to remove all the frames on the hydraulic climbing formwork, hoist it to the site under the bridge to adjust the angle, and then re-install it. This method There are the following problems: (1) It is easy to cause deformation of the flexible rods and templates of the upper frame
(2) The risk of high-altitude operation is high for the operators who install the lower frame, and the requirements for the stacking site are high
(3) The workload of reassembly and disassembly of the frame is too large, the construction time is long, the efficiency is low, and the construction period is seriously affected

Embodiment 1

[0049] Such as Figure 1-6 The structure diagram of the hydraulic climbing formwork conversion system shown includes the upper frame body 1, the formwork structure 2, the main platform load-bearing connection structure 3, the attached tower hydraulic sliding structure 4, the lower frame body 5, the formwork brace 6, the formwork 7, and the sliding platform 8. Embedded parts 10, embedded parts hanging seat 11, guide rail 12, hydraulic drive device 13, tripod beam 14, tripod brace 15, tripod pole 16, pin hinge 17, Y-shaped tower column 25, middle Tower column conversion base segment 26, upper tower column conversion base segment 28, etc. The hydraulic climbing formwork conversion system mainly consists of upper frame body 1, formwork structure 2, main platform load-bearing connection structure 3, attached tower hydraulic sliding structure 4 and The structure of the hydraulic climbing formwork conversion system is basically the same as that of the traditional hydraulic climbing f...

Embodiment 2

[0060] This patent also provides a construction method for the hydraulic climbing formwork conversion system, including the following steps:

[0061] (1) Universal configuration and numbering of hydraulic climbing formwork: According to the section size of the lower tower column section of Y-shaped tower column 25, a common hydraulic climbing formwork conversion system is equipped on each side of the pier tower. For the four sides of Y-shaped tower column 25 The hydraulic climbing formwork is numbered, the upper frame body 1 in the direction of the bridge is numbered A1, A2 and B1, B2 respectively, and the lower frame body 5 in the direction of the bridge is numbered A1', A2', B1', B2' respectively. The upper frames 1 facing the bridge are numbered C1, C2 and D1, D2 respectively, and the lower frames 5 along the bridge are numbered C1', C2', D1', D2' respectively.

[0062] (2) Pre-embedding of embedded parts: When the lower tower column is constructed vertically upwards, the e...

Abstract

The invention relates to a construction method for a hydraulic climbing formwork conversion system of a special-shaped pier tower, comprising steps: S1, hydraulic climbing formwork configuration and numbering; S2, pre-embedded parts; S3, foundation segment concrete pouring; S4, climbing formwork platform Cleaning; S5, remove the upper frame body A1 to the ground; S6, lift the lower frame body A1'; S7, install the upper frame body B1 and lift B1'; S8, install the upper frame body B2 and lift the lower frame body B2'; S9, upper frame body A2 Install and lift the lower frame body A2'; S10, install the upper frame body A1; S11, climb the hydraulic climbing form along the bridge; S12, bind the steel bars and pour concrete. The beneficial effects of the present invention are: the present invention adopts the climbing formwork conversion system at the variable cross-section of the tower column to carry out cyclic replacement and disassembly to achieve the purpose of system conversion. Only one side of the upper frame body needs to be hoisted to the ground, and the lower frame body continues to be lifted and fixed. On the one side, the lower frame bodies that have been lifted one by one can be used as the basis for cyclic replacement, disassembly and installation.

Description

technical field [0001] The invention relates to a construction method for a hydraulic climbing formwork conversion system of a special-shaped pier tower, which is mainly applicable to the conversion construction of the hydraulic climbing formwork system of "A-type", "H-type" and "Y-type" special-shaped pier towers. Background technique [0002] With the deepening of concepts such as "landscaping" and "integrating scenery", bridges crossing V-shaped valleys in mountainous areas are often designed as cable-stayed bridges, and the structural forms of cable-stayed bridge piers are also various, mainly including "A-shaped", "H type", "Y type" and so on. According to different pier tower structures, the crossing of pier towers or the consolidation positions of tower girders are different, and the construction techniques are different. The pier towers or tower girders can be constructed in "synchronous" and "asynchronous" constructions. When the intersection or tower beam is conso...
