Description
Technical field
The invention belongs to building field more particularly to a kind of super high-rise building Core Walls Structure horizontal structure construction methods.
Background technique
With the development of the city, population is more and more, and soil is fewer and fewer, and (i.e. height is greater than 100m's for super high-rise building
Building) it continues to bring out.Super high-rise building is designed as frame core wall structure more, and Core Walls Structure mainly uses the systems such as creeping formwork or backform
It constructs, Core Walls Structure vertical structure is suitble to construct in advance, horizontal structure lag construction, and speed of application is slow compared with vertical structure.
Core Walls Structure wall is constructed in advance, is inserted into not in time if constructing after horizontal structure, and Core Walls Structure wall will be more next with horizontal structure height difference
Bigger, wall stiffness weakens, and design margin evaluation reduces, while measurement accuracy is not easy to control；Construction reinforced bar is planted after horizontal structure
Muscle connects that project amount is big, time-consuming work consuming, and will affect structure tension performance and safe service life；Pre-buried moment reinforcement straightening
Afterwards, plasticity seriously reduces and brittleness increases, and is not able to satisfy mechanical property requirements.
Summary of the invention
Technical problem to be solved by the present invention lies in providing a kind of super high-rise building Core Walls Structure horizontal structure construction method,
Prior art progress to be solved is slow, the uppity defect of construction quality.Technical scheme is as follows: a kind of Super High is built
Build Core Walls Structure horizontal structure construction method, it is characterised in that include the following steps:
S1: Construction Arrangement, Core Walls Structure horizontal structure section construction technology, super-high building structure use backform or creeping formwork system
When system construction, when Core Walls Structure wall is constructed with backform to index bed n-layer, according to construction horizontal layout and design feature, choosing
Select the girder steel of Deepen Design, profiled sheet composite structure replaces original (n-m) layer concrete horizontal structure, be that support is flat with the layer
Platform carries out (n-m+1) layer horizontal structure support for shuttering and sets up；When Core Walls Structure wall is constructed with backform to index bed (n+m) layer,
It selects the girder steel of Deepen Design, profiled sheet composite structure to replace original Ln layer concrete horizontal structure, is that support is flat with the layer
