Problems solved by technology

[0004] see figure 1 As shown, due to the change of the core tube structure, the design elevation of the concrete structure 2 and the corbel 10 of the box girder 1 will be inconsistent, and the corbel 10 of the individual box girder 1 will often encounter the opening 3 under the coupling beam (such as a window door hole or door opening of the elevator), the corbel 10 is in a suspended state, resulting in the fact that the corbel 10 supporting the box girder 1 has no stress point, which affects the safety of the jacking platform

Embodiment 1

[0034] combine Figure 1 to Figure 3 As shown, the present invention provides a jacking platform box girder support structure and construction method thereof for super high-rise buildings, wherein, the upper group of jacking platform box girders are respectively supported through the reserved openings 99 on the shear wall 2 1 and the lower group of jacking platform box girder 1', a shear wall opening 3 is formed on the right shear wall 2, and the right end of the upper group of jacking platform box girder 1 is just within the height range of the shear wall opening 3 Furthermore, the corbel 10 at the right end of the jacking platform box girder 1 of the group is suspended in the air, and the two ends of the jacking platform box girder 1' of the lower group are respectively supported in the corresponding reserved openings 99 on the shear wall, such as image 3 , in order to solve the problem of the suspension of the box girder corbels, the application is provided with a temporar...

Embodiment 2

[0038] On the basis of Embodiment 1, there are two sets of jacking platform box girders within the height range of the shear wall opening 3, and the upper set of jacking platform box girders 1 includes the first box girder 11 with one end suspended in the air and the The second box girder 12 and the lower group jacking platform box girder 1 ′ include a third box girder 13 and a fourth box girder 14 supported on the bottom surface of the opening 3 of the shear wall. In order to solve the box girder support in this case, the application selects a lattice column support 4a with a wide top and a narrow bottom, and supports the upper end of the lattice column support 4a on the first box beam 11 and the second box beam 11. Below the corbel 10 of the box girder 12 , the lower end base of the lattice column support 4 a is supported on the bottom surface of the shear wall opening 3 between the third box girder 13 and the fourth box girder 14 . The other structures are basically the sam...

Embodiment 3

[0040] Such as Figure 6 As shown, the application also discloses another suspended state of the box girder. In the figure, only the box girder 1 of the upper group jacking platform is within the height range of the shear wall opening 3. This suspended state and figure 2 In contrast, the difference of this kind of suspended state is that the combination of Figure 7 As shown, the shear wall opening 3 is inverted L-shaped and has a vertical opening section 30 and a horizontal opening section 32, the horizontal opening section 32 has a supporting shear wall 20, and the right end of the first box girder 11 The corbel 10 is suspended in the horizontal opening section 32 , and the right end corbel 10 of the second box girder 12 is located at the intersection of the vertical opening section 30 and the horizontal opening section 32 to be suspended in the air. In order to solve the box girder support in this case, this application proposes another temporary support frame structure, ...

Abstract

The invention provides a lifting platform box girder support structure for super high-rise buildings and a construction method thereof, wherein the lifting platform box girder support structure comprises a lifting platform and a box girder arranged at the bottom of the lifting platform, a support corbel is arranged at the end part of the box girder, a shear wall of a super high-rise building is provided with a support end corresponding to the support corbel, a hole is formed in a position of the shear wall corresponding to the support corbel of at least one box girder, and a temporary support frame is arranged in the hole position to underprop the support corbel. The lifting platform box girder support structure for super high-rise buildings provides a supporting point for the box girder in the hole position of the shear wall, thereby better ensuring safety of the lifting platform.

Description

technical field [0001] The invention specifically relates to a box girder supporting structure of a jacking platform for a super high-rise building and a construction method thereof. Background technique [0002] With the advancement of science and technology and the improvement of construction technology, there are more and more super high-rise large buildings. The horizontal structure and vertical structure in the super high-rise core tube structure are often constructed separately. The core tube vertical structure adopts a self-climbing formwork system- Overall jacking platform. [0003] In the super high-rise overall jacking platform, it includes a jacking system, a truss system, a hanger system and a formwork system. In the jacking system, the pressure of the oil cylinder is used to provide the jacking force, and the reserved openings in the shear wall are used to provide force for the supporting box girder. The fulcrum realizes the climbing of the entire jacking platf...
