Problems solved by technology

[0004] Therefore, a cast-in-place hollow floor is developed for high-rise buildings, especially the solid floor between the outer frame beams of the frame core cylinder and the core cylinder adopts a hollow floor to reduce the weight of the high-rise and enhance the overall performance of the system , and is beneficial to earthquake resistance; the traditional solid floor between the outer frame beam column and the core tube is changed to a two-way dense rib floor with lower flange sealing and a cast-in-place hollow floor with one-way groove floor, which overcomes the self-weight of the existing technology , at the same time optimize the joints at the four corners of the core tube and apply the solid parts around the side columns; the filling body for hole formation makes full use of the surface tension of the concrete, changes t

Embodiment Construction

[0022] The invention will be further described below in conjunction with the accompanying drawings.

[0023] figure 1 It is the plan view of the high-rise building of the first embodiment of the present invention, the high-rise building of the frame core tube structure is made of the core tube 11 at the central part of the building plane, the outer frame 12 and the floor 18; the hollow floor of the high-rise building with the frame core tube structure The technology must be clear about "one frame and one tube, four points and four sides, eight lines and multiple units, and trough floor"; "one frame" is the outer frame with 12 beams and columns, and the height of the side beams should be larger, preferably 1.2m. The number and cross-sectional area of ​​the columns are determined according to the vertical load; the "one tube" is the core tube 11, and the elevator tube and service workshop are generally concentrated in the core tube; the outer edge of the core tube is surrounded ...

Abstract

The invention provides a high-rise building adopting cast-in-place hollow floors. The high-rise building is formed by a core tube, an outer frame, hollow floors, and a steel mesh and organic object combined cavity; the core tube is of a closed space structure formed by shear walls in four directions at the central part of a building plane; the outer frame is a frame stress component formed by outer edge beam columns of the building plane; main beams are reinforced concrete combined beams or profiled-steel beams; steel meshes and organic objects act upon each other; the steel meshes form the cavity top surface and the cavity bottom surface of the combined cavity and two side walls of the cavity side faces; the organic objects comprise air bags or polyphenyl blocks; the organic objects form the other two side walls of the side faces of the combined cavity of the steel meshes, are supported between the cavity top surface and the cavity bottom surface, and are used for controlling the height of the combined cavity of the steel meshes. After the steel mesh and organic object combined cavity is put in place, concrete is deposited, vibration and ramming and maintenance are carried out, and floor templates are dismantled, so that the application of the cast-in-place hollow floors in the high-rise building is realized.

Description

technical field [0001] The invention relates to a high-rise building, in particular to a high-rise building with a cast-in-place hollow floor. Background technique [0002] The structural system of high-rise buildings includes the horizontal structural system of the floor and the vertical structural system of walls and columns. The horizontal structure and the vertical structure form the lateral space structure of the building, and jointly resist the lateral force. The rigid floor uses its infinite stiffness in the plane to resist the horizontal displacement, and the vertical column bears and transmits the vertical load; the structural system of high-rise buildings mainly includes frame structure, shear wall structure, frame-shear wall structure, frame-core tube structure, tube-in-tube structure, steel-concrete hybrid structure, etc. [0003] At present, steel-concrete buildings are mostly used in super high-rise buildings, which are characterized by high strength, high rig...
