Abstract
The invention discloses an emergency system building method under synchronous construction of a horizontal structure of a core barrel and a top mold. When the core section of thick bamboo vertical structure is under construction to the top mould, select one or polylith horizontal floor and core section of thick bamboo vertical structure synchronous construction in the outside round within range of core section of thick bamboo to reserve the entrance to a cave of setting up sparse stair in the horizontal floor of construction, communicate from top to bottom through setting up the stair between each layer horizontal structure, thereby another passageway of the upper and lower top mould outside the construction elevator has been formed, the personnel of being convenient for are sparse when emergency, also can strengthen core section of thick bamboo vertical structure's stability.
Description
Technical Field
The invention belongs to the field of high-rise building construction, and particularly relates to an emergency system building method under synchronous construction of a horizontal structure of a core barrel and a top formwork.
Background
The super high-rise structure is mainly an outer steel frame and a core tube structure, the super high-rise structure adopts a top mould to construct a core tube vertical structure in advance, a horizontal structure in a core tube and an outer frame horizontal structure are constructed together, and the construction of the horizontal structure is usually lagged behind the core tube vertical structure by 10-15 layers;
the current construction mode is for only carrying out the vertical structure construction, and the constructor passes through the elevator loading from top to bottom the mould, and when emergency, after stopping power supply, constructor will be unable to evacuate from the mould, constitutes very big potential safety hazard.
Disclosure of Invention
The invention aims to provide an emergency system building method for overcoming the defects in the prior art that a horizontal structure of a core barrel and a top die are constructed synchronously. In order to achieve the technical purpose, the technical scheme adopted by the invention is as follows:
a method for building an emergency system under synchronous construction of a horizontal structure and a top formwork of a core tube is characterized in that when the core tube structure rises to the height of each floor of a main building, the horizontal structure corresponding to each floor is synchronously poured, platforms are built between any two or more vertical structure intervals at the edges of the core tube, and the time of every two adjacent layers of platforms is communicated through evacuation stairs.
Further limiting, the evacuation stairs are formed by erecting steel pipes or are formed by single-run shaped steel stairs.
Further limiting, holes are reserved on each layer of platform, and the evacuation stairs are communicated with the next layer of platform through the reserved holes of the upper layer of platform.
Further inject, every layer of platform is convenient for all be provided with the protection rail.
Further limiting, the holes are covered with protective nets.
Compared with the prior art, 1, under the working condition of top formwork construction, the construction of the horizontal structure of the local core barrel does not occupy the construction period of the vertical structure, and the construction efficiency of the top formwork system is improved.
2. The evacuation stair is erected by utilizing the synchronously constructed platform, the problem that constructors escape from the top die in an emergency is solved, and the evacuation stair has the advantages of simplicity and convenience in operation, low cost and the like.
3. The evacuation stair can be used as an upper channel and a lower channel outside the construction elevator, and even if the construction elevator fails, the evacuation stair can keep smooth traffic between the upper steel platform and the lower large flat layer.
4. And part of horizontal structures and vertical structures are constructed synchronously, so that the structural stability of the core barrel in the construction process is enhanced.
