Problems solved by technology

[0005] The present invention provides a support system and construction method for a high-altitude cantilevered construction platform. The force of the scaffolding roof system is not clear, it is difficult to establish a reasonable force model, and it is easy to produce lateral deflection, the rigidity is small, and the strength of the joints cannot be guaranteed. In addition, the erection of the support system requires a lot of work and high risk, which raises the construction threshold. question

Embodiment 1

[0045] like Figure 1 to Figure 3 The support system of a high-altitude cantilevered construction platform is set under the support system of the formwork and scaffolding of the upper cantilevered concrete member, including the floor slab 1, the concrete structural column 6, the structural edge beam 10 and the scaffolding of the outer wall 16, including the cantilevered safety An operation platform and a cable-stayed force-bearing support system, the cantilevered safety operation platform is located below the cable-stayed force-bearing support system,

[0046] The cantilever safety operation platform includes the following structures:

[0047]The floor 1 located on the upper floor of the cantilever safety operation platform is provided with a wire rope suspension ring 2, and the concrete structure column 6 is provided with 3 layers of steel pipe hoops 5, and the steel pipe hoops 5 are provided with cross bars. The cross bar includes a platform cross bar 15 and a supporting cr...

Embodiment 2

[0067] The rest are the same as in Embodiment 1, the difference being that the setting interval of the main stressed beam 3 is a horizontal distance of 2m; A 12m-long 36a I-beam cantilevered over 2m is used as the main force beam 3 of the cable-stayed support system.

Embodiment 3

[0069] The rest are the same as in Embodiment 1, the difference being that the setting interval of the main stressed beam 3 is a horizontal distance of 3m; A 12m-long 36a I-beam cantilevered by 3m is used as the main force beam 3 of the cable-stayed support system.

[0070] Through practice, the present invention can effectively avoid the mutual influence with the construction of the external wall, effectively reduce the construction period, save more than 75% of the erection cost compared with the floor-to-ceiling scaffolding, has high technical content, is environmentally friendly, energy-saving and material-saving, and has broad application prospects.

Abstract

The invention provides a high-altitude cantilever construction platform support system and a construction method thereof. The high-altitude cantilever construction platform support system is arrangedbelow an upper cantilever concrete component formwork scaffold supporting system and comprises a floor, concrete structural columns, structural boundary beams, an outer wall scaffold, a cantilever safe operation platform and a diagonal tensile stress supporting system. The cantilever safe operation platform is located below the diagonal tensile stress supporting system. The problems that a full-hall floor-type steel pipe roof propping system is adopted and cannot be constructed simultaneously with a cantilever structure, and the construction period is prolonged, and the problems that an adopted cantilever-type scaffold roof propping system is undefined in stress, a reasonable stress model is hard to build, lateral deflection is prone to being generated, rigidity is small, the joint strength cannot be ensured, the high-altitude hanging work amount of supporting system erecting is large, dangerousness is high, and the construction threshold is raised are solved.

Description

technical field [0001] The invention relates to the field of engineering construction, in particular to a high-altitude cantilevered construction platform support system and a construction method. Background technique [0002] In all kinds of buildings in our country, cantilevered concrete structures are widely used. In the construction of cantilevered concrete structures, floor-mounted full house scaffolding or cantilevered scaffolding are usually used as the roof support system. [0003] With the full house floor-standing steel pipe support system, the construction of the exterior wall and curtain wall can only be carried out after the cantilever structure is completed, and it cannot be constructed at the same time as the cantilever structure, because the overlapping part of the original external scaffold and formwork does not meet the requirements of high formwork, and must The high formwork was dismantled and rebuilt. After the cantilevered slab structure and decoration...
