a construction method

Abstract

The invention discloses a building construction method. A conversion layer is arranged in the core tube area of a main building, and can provide support for the core tube of the main building to be constructed, so that after addition of the conversion layer, the construction of the core tube of the main building above the conversion layer can be conducted without waiting totally downward reverse operation of a podium from the top plate to the baseplate of a basement, that is, the construction of the core tube of the main building is inserted in advance; the construction of the structure above the conversion layer is not influenced by uncontrollable factors in the reverse stage of the basement, and the influence on the total construction period is less, so that the provided building construction method can ensure the sequential construction time of the core tube of the main building and ensure the construction period of the main building.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a building construction method. Background technique [0002] Digging the foundation pit first, and then building the building layer by layer from bottom to top is the traditional way of building tall buildings. The reverse method breaks people's traditional concepts. It uses the beams, slabs, columns, and outer walls of the basement as the supporting structure of the construction, and constructs the underground structure of the high-rise building layer by layer from top to bottom. At the same time, due to the top structure of the basement The completion of the building creates conditions for the construction of the upper structure, so the construction of the above-ground structure can also be carried out layer by layer at the same time. [0003] With more and more super high-rise buildings in China, the reverse method is being used more and more. In the construction proces...

Problems solved by technology

In the construction process of the existing technology, the construction of the core tube of the main building needs to be constructed after the podium is reversed from the basement roof to the bottom slab; and for the ultra-deep basement, the reverse operation period of the podium is long, and the core tube of the main building There is a lag in the time for the parallel operation, and there are many uncontrollable factors in the reverse operation stage of the basement, such as earthwork excavation and outbound transportation, weather and the embargo of the competent authority, etc., which seriously affect the reverse operation period

The uncertainty of the construction period of basement reverse work is large, and the risk of the construction period of the main building is high
