Problems solved by technology
However, the application of hanging formwork construction in the construction of super high-rise buildings has prominent problems: first, the installation and removal of formwork in hanging formwork construction itself is relatively cumbersome; The third is that the formwork hanging construction is limited by the concrete solidification time, and the construction period is long; the fourth is that the formwork hanging construction needs to build a large supporting scaffold. In order to make the supporting scaffold stable, a large operating platform needs to be built. It is also very difficult and costly to operate the operating platform at high altitude

Embodiment Construction
[0020] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0021] Such as figure 1 , figure 2 as well as image 3 As shown, a flange device disclosed in the present invention is used in the construction method of the reserved opening of the structure, which specifically includes the following construction steps. In this case, a floor slab with a thickness of 120mm is used as an example to illustrate:
[0022] S1: After the steel structure has completed the installation of the profiled steel plate 7 and the binding of the floor steel bars 8, conduct on-site measurement and setting out of the reserved openings on the floor plane to obtain the plane positions of all reserved openings;
[0023] S2: Select the specification of the flange device according to the thickness of the floor structure;
[0024] The structure of the flange in this case is as follows figure 2 As shown: the flange device includes a flange tube...

The invention discloses a method using a flange device for structural reserved hole construction. The method mainly utilizes the flange device to construct a reserved hole, and the construction process comprises the steps of measurement positioning, flange device installation and use and the like. Compared with a hanging template in the prior art, the flange device directly plays a role in supporting a floor slab structure through the combination of a flange cover and a flange cylinder, when the reserved hole is blocked in the later period, any operating platform is not required to be erectedbelow a floor slab, only the flange cover requires to be fixedly connected to the flange cylinder and secondary structural concrete is used for sealing, so that the construction is very simple, and the construction cost is very low compared with a hanging template construction mode.
Description
technical field [0001] The invention belongs to the technical field of super high-rise building construction, and in particular relates to a construction method for a flange device used in a structure reserved opening. Background technique [0002] With the development of the modern economy and the continuous advancement of construction technology, viewing bridge corridors designed between super high-rise buildings continue to emerge, and the bottom of the corridors is mostly made of lightweight and high-strength aluminum curtain wall systems. Limited by construction technology, the aluminum panel curtain wall system needs to reserve openings in the corridor floor structure (generally, the diameter of the reserved opening is 165mm) for hoisting and lifting of the aluminum panel curtain wall. After the hoisting is completed, the reserved opening needs to be closed. [0003] In the prior art, for such reserved openings that need to be closed later, the hanging formwork is gen...
