Technical Field
The invention relates to the field of building construction, in particular to a construction method of a box-type structure conversion layer of a super high-rise building.
Background
With the continuous development of city construction, more and more high-rise or super high-rise buildings adopt conversion layers to meet the requirements of conversion of different building functions. The conversion layer structure has the characteristic of bearing large load of an upper structure, so that the section size of the conversion girder is large, and construction joints (horizontal and vertical) are not allowed to be reserved in the concrete of the conversion layer girder in the construction process so as to ensure the stressed integrity of the concrete structure. For the box-type structural conversion layer, if a conventional construction method is adopted for construction, the vertical members (columns and walls) of the conversion layer are generally constructed firstly, then the lower floor slab of the box-type structural conversion layer and the lower concrete of the conversion girder are constructed, and finally the upper concrete of the girder of the conversion layer and the upper floor slab of the conversion layer are constructed.

Aiming at the defects of the prior art, the technical problems to be solved by the invention are as follows: how to provide a construction method of a box type structure conversion layer of a super high-rise building, which can avoid the generation of construction joints and improve the structural safety.
In order to solve the technical problems, the invention adopts the following technical scheme:
a construction method of a box type structure conversion layer of a super high-rise building comprises the following steps:
1) performing reinforcement construction of the wall column on the constructed floor;
2) formwork supporting construction is carried out on the wall columns and the lower layer plate of the conversion layer, and meanwhile formwork supporting construction is carried out on a main beam bottom mould of the conversion layer;
3) carrying out reinforcement binding construction on the main beam of the conversion layer;
4) arranging a separation net for preventing the poured concrete of the lower layer plate of the conversion layer from flowing to the bottom die of the main beam of the conversion layer at the junction of the lower layer plate template of the conversion layer and the side face of the bottom of the main beam steel bar of the conversion layer, and binding the separation net on the main beam steel bar of the conversion layer;
5) binding reinforcing steel bars of the lower layer plate of the conversion layer on the template of the lower layer plate of the conversion layer, wherein the reinforcing steel bars of the lower layer plate of the conversion layer and the part corresponding to the main beam reinforcing steel bars of the conversion layer penetrate through the separation net and extend into the main beam reinforcing steel bars of the conversion layer to be bound together with the main beam reinforcing steel bars of the conversion layer;
6) carrying out concrete pouring on the wall columns and the lower layer plate of the conversion layer;
7) after the concrete of the lower layer plate of the conversion layer is solidified, constructing a side mold of a main beam of the conversion layer and a formwork of the upper layer plate of the conversion layer;
8) binding steel bars of the upper layer plate of the conversion layer on the upper layer plate template of the conversion layer;
9) carrying out concrete pouring on the main beam of the conversion layer and the upper layer plate of the conversion layer;
10) and after the main beam of the transfer floor and the upper floor slab of the transfer floor are solidified, removing all the templates.
In conclusion, the beneficial effects of the invention are as follows: after the wall column template, the lower plate template and the bottom formwork of the main girder of the conversion layer are constructed, the reinforcement construction of the main girder of the conversion layer is firstly carried out, then the separation net is utilized to block, the concrete is prevented from automatically flowing to the bottom formwork of the main girder of the conversion layer in the concrete pouring process of the lower plate of the conversion layer, and the later-stage formation of a construction joint is avoided. In addition, the separation net can penetrate through the lower plate steel bars of the conversion layer more easily to extend into the main beam steel bars of the conversion layer compared with the traditional template, the leakage of concrete can be reduced, the template does not need to be detached after the lower plate concrete of the conversion layer is formed, after the main beam concrete of the conversion layer is poured, the connectivity between the main beam concrete of the conversion layer and the lower plate concrete of the conversion layer is stronger, and the improvement of strength is facilitated. By changing the construction method, the construction problem that the construction joints are reserved on the girder of the box type structure conversion layer is solved, the construction specification of the box type structure conversion layer is met, and the construction quality is improved.
