Problems solved by technology
[0003] 1) The distance between adjacent buildings, especially high-rise buildings, is relatively large, and the corresponding corridors have large spans. The weight of the structural parts forming the aerial corridors is too large, and it is not suitable for overall hoisting after assembly;
[0004] 2) The installation height of aerial corridors is generally very high, and it is difficult to erect scaffolding for aerial work, with poor stability and low safety factor;
[0005] 3) The hoisting operation is complicated and changeable, which consumes a lot of manpower, material and financial resources, and the economic effect is poor

Embodiment Construction
[0039] The present invention will be further described below in conjunction with specific examples, but the protection scope of the present invention is not limited thereby.
[0040] See Figure 1-Figure 8 Shown, the construction method of a kind of super high-rise aerial corridor structure that the present invention relates to, comprises the following steps:
[0041] 1) Cantilever platform installation (see image 3 ): set several tripods 2 at equal intervals on the outer wall of the tower concrete structure 1 on the next floor of the proposed air corridor, and lay three groups (two for each group) of square steel keels 11 along the outer detection section of the tripods 2, each The square steel keel 11 passes through at least three tripods 2 and is cross-lapped. The square steel keel 11 is laid with 18mm thick wood boards 3; Railings 5 and safety protection railings 5 are connected and reinforced by double-purpose crossbars; skirting boards 4 are set on the outer detec...

The invention relates to a construction method of a super-high-rise aerial corridor structure. A cantilevered platform is built on the next construction level of the installation position of the aerial corridor, and the existing tower crane on the construction site is used to simultaneously lift the steel structure beam and connect it with the corresponding The two adjacent towers are fixedly connected, and then the operation platform and safety rope protection are built on the steel structure beams. Finally, the formwork support and concrete pouring of the air corridor are carried out on the basis of the steel structure beams to complete the construction of the air corridor. The beneficial effects are as follows: 1) solves the problem that the span of the corridor is large, and the weight of the structural parts constituting the corridor in the air is too large, which is not suitable for overall hoisting after assembly; 2) the use of tower cranes for on-site construction can save hoisting costs; 3) There is no need to set up scaffolding for high-altitude operations, which improves the construction safety factor; 3) The structure of the operation platform is simple, easy to manufacture and install, which can effectively speed up the construction speed; 4) The formwork scaffolding is simple to construct and reduces the difficulty of construction; 5) The safety protection system is simple, safe and reliable .
Description
technical field [0001] The invention relates to the technical field of steel-concrete structure construction, in particular to a construction method for a super high-rise aerial corridor structure. Background technique [0002] With the development of engineering construction, the level of engineering construction has been improved year by year. In order to demonstrate the originality and perfect artistic conception of the architectural style, innovations and changes are constantly being made in the plane layout, shape composition, artistic treatment and application of techniques of the building. There are frequent cases of connecting adjacent buildings with aerial corridors. At present, the construction scheme of the traditional cast-in-place reinforced concrete aerial corridor usually adopts a full-scale scaffolding to build to the construction floor, or adopts the method of two-way lifting equipment to climb the prefabricated concrete components to the construction floor ...
