[0002] With the development of the real estate industry, high-rise buildings are increasing day by day, and the design styles of buildings are also diversified. Therefore, in high-rise buildings, the span of the beam between the core tube and the outer ring frame is getting larger and larger; however, due to the restrictions on the storey height and the requirements for reasonable use of space by developers, the height of the beam section is limited. In this case, the height of the outer frame beam designed according to the normal requirements cannot meet the net height requirements of the building, which makes it difficult for the ordinary concrete beam-slab structure system to meet the requirements of the building function.

[0003] In order to ensure the height of reasonable use of space, although the existing prestressed concrete large slab structure can meet the requirements of building space, this structure has problems such as strict requirements on construction technology, complex construction and high construction cost, so it is not conducive to widespread promotion and application.

[0045] See also Figure 1 The embodiment of the present invention provides a building structure system, including a core tube 3, an outer ring frame and a variable section plate 1, wherein the core tube 3 is located in the middle of the building, the outer ring frame includes frame columns 4 and outer frame beams 5, the frame columns 4 and the outer frame beams 5 are located outside the core tube 3, and adjacent frame columns 4 are connected by outer frame beams 5 to form an outer ring frame. The variable section plate 1 is connected between the core tube 3 and the outer ring frame, and the core tube 3 and the outer ring frame are connected by the variable section plate 1, and the variable section plate 1 includes a first connecting portion 11, a second connecting portion 13 and a transverse plate 12.

[0046] See also Figure 2 The first connection part 11 and the second connection part 13 are respectively arranged at both ends of the horizontal plate 12 and connected to the horizontal plate 12 as a whole. The first connection part 11 is connected to the outer ring frame, and the second connection part 13 is connected to the shear wall 31 of the core tube 3. The thickness of the horizontal plate 12 is less than that of the first connection part 11 and the second connection part 13. The thickness of the first connection part 11 and the second connection part 13 are the same or different.

[0047] The embodiment of the present invention cleverly arranges the first and second connecting parts 13 and the transverse plate 12 so that the variable-section plate 1 still has a high bearing capacity and good crack resistance under the action of vertical load, has good economic benefits and high safety reserves, and meets design requirements and engineering needs.

[0048] In an embodiment of the present invention, the thickness of the horizontal plate 12 is set to be smaller than the thickness of the first and second connecting parts 13, which can effectively save the floor height and realize the free division of the indoor space; and correspondingly, a steel bar structure is cleverly arranged in each component, which can effectively transfer the internal force between the core tube 3 and the outer ring frame when the floor height is limited, thereby realizing synergy.

[0049] In some embodiments, see Figure 2 Along the direction from the core tube 3 to the outer ring frame, the length of the first connecting part 11 satisfies the relationship: l1=L / 4~L / 3, and the length of the second connecting part 13 satisfies the relationship: l2=L / 4~L / 3, wherein l1 is the length of the first connecting part 11, l2 is the length of the second connecting part 13, and L is the length of the variable-section plate 1. The first connecting part 11 and the second connecting part 13 are in favorable positions in terms of force, meeting the strength and specification requirements.

Considering the large load bending moment and shear force at the connection and the requirements of the reinforcement ratio, the thickness t2 of the first connection part 11 and the second connection part 13 located at the outer ring frame side and the core tube 3 side must be greater than the thickness t1 of the transverse plate 12, and the thickness t2 must also meet the requirements of reasonable use of the building space height.

[0051] The variable cross-section plate 1 can be formed by assembly or integral molding. In some embodiments, the variable cross-section plate 1 is cast in situ or prefabricated with concrete. Figure 1 , Figure 3 A hidden beam 2 is provided in the variable section plate 1 corresponding to the frame column 4. One end of the hidden beam 2 is connected to the frame column 4, and the other end is connected to the shear wall 31. The bearing capacity of the variable section plate 1 is greatly improved by providing the hidden beam 2. While ensuring the structural strength, the thickness of the transverse plate 12 is reduced. Among them, the width of the hidden beam 2 satisfies the relationship: T≥B+2t2, where T is the width of the hidden beam 2, B is the width of the frame column 4, and t2 is the thickness of the first connection part 11 or the second connection part 13, which meets the 45° shear resistance requirement. Among them, the transverse reinforcement of the hidden beam 2 is composed of outer stirrups 21 and internal tension bars 22. The internal tension bars 22 are staggered, and the bottom bars and surface bars 14 are anchored into the core tube 3 and the outer ring frame according to the requirements of tensile and seismic anchoring to improve the bearing capacity of the hidden beam 2.

[0055] Furthermore, the transverse plate bottom reinforcement 121 is anchored in the first connection part 11 and the second connection part 13, and the anchoring length of the single-side transverse plate bottom reinforcement 121 satisfies the relationship: L5≥10d3, wherein L5 is the anchoring length of the transverse plate bottom reinforcement 121, and d3 is the diameter of the transverse plate bottom reinforcement 121, so as to ensure the connection strength between the transverse plate 12 and the first connection part 11 and the second connection part 13.
