[0002] The core tube is usually located in the central part of a building. The central core tube is formed by enclosing an elevator shaft, a staircase, a ventilation shaft, a cable shaft, a public toilet, and part of an equipment room, and forms an outer frame-inner tube structure with the outer frame, which is cast with reinforced concrete. This structure is very beneficial to the structural force and has excellent seismic resistance. It is one of the mainstream structural forms widely adopted in international super high-rise buildings.
[0003] During the conventional construction of a super high-rise hybrid structure, since the core tube is a cast-in-place reinforced concrete structure and the outer frame is a steel structure + a reinforced steel truss floor slab or a profiled steel sheet composite floor slab, the concrete core tube is usually constructed first, and then the surrounding steel structure and floor slab are constructed. To improve the construction efficiency of the core tube, the core tube usually adopts an integral climbing construction platform for construction. The steel bars of the core tube shear wall need to be lapped with the steel bars of the peripheral floor slab to form an integral entity inside and outside and ensure the transfer of the internal force of the floor slab during an earthquake. Therefore, reserved steel bars are generally set outside the shear wall, and the reserved steel bars of the shear wall often block the climbing of the integral construction climbing frame of the core tube.

Calculate according to the full force of the embedded steel bar group 5 and the lapped steel bar group 8, so as to determine the model of the connecting bolt 10 and the sizes and thicknesses of the embedded plate 3 and the connecting plate 7;
[0071] Among them, when the embedded steel bar group 5 and the lapped steel bar group 8 are under tensile action, a large out-of-plane bending moment will be generated on the embedded plate 3 and the connecting plate 7. It is necessary to ensure the stiffness of the embedded plate 3 and the connecting plate 7 to avoid excessive deformation under force.
[0072] In an alternative embodiment, the connecting bolt 10 is a sleeve high-strength connecting bolt or a twist-off type self-locking high-strength one-way bolt.

[0089] like Figure 7 , Figure 8 As shown, based on Example 1, the steel bar mechanical connection structure of the core tube and the surrounding floor slabs described in this embodiment also includes a bearing plate 9, which is connected to the bottom of the connecting plate 7 and extends to the side away from the embedded plate 3.
[0090] By arranging the bearing plate 9 on the connecting plate 7, the bearing plate 9 can be used as a support member, as a support during the construction stage of the floor 30, so that when it is inconvenient to set up the bracket of the floor 30, the bearing plate 9 can be used to support the floor 30, so as to carry out the construction of the floor 30;
[0091] Or, if Figure 7 As shown, the floor 30 is perpendicular to the shear wall 20, that is, the supporting direction of the floor 30 is perpendicular to the shear wall 20. At this time, the lap steel bar group 8 is subjected to greater force, and the floor 30 is supported by the load-bearing plate 9 to increase the overall strength of the entire connection assembly 6.
[0092] In an optional embodiment, the load-bearing plate 9 is a steel plate, which is welded to the bottom of the connecting plate 7 and extends toward the floor slab 30 .

[0096] Floor slab reinforcement bars 40 are arranged in the floor slab 30 , and the connecting assembly 6 is used for overlapping the floor slab reinforcement bars 40 .
[0097] For the combined structure of the core tube and the floor slab described in this application, the embedded component 1 is embedded in the shear wall 20. After the core tube is constructed, the connecting component 6 is fixed on the embedded component 1, and then the floor slab steel bars 40 are lapped on the connecting component 6. After pouring the connecting component 6 and the floor slab steel bars 40, the floor slab 30 is formed, thereby connecting the floor slab 30 to the shear wall 20 of the core tube. During the construction process, since the connecting component 6 is installed after the core tube is constructed, it will not affect the climbing of the construction climbing frame of the core tube, avoiding the problem that in the traditional method, steel bars need to be reserved on the shear wall 20 of the core tube, and the reserved steel bars will block the climbing of the overall construction climbing frame of the core tube, greatly improving the construction efficiency of the core tube.
[0098] As Figure 5 shown, when the floor slab steel bars 40 are lapped on the connecting component 6, the floor slab steel bars 40 are tied to the lapping steel bar group 8.
[0099] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
