Description

Technical Field

[0001] The utility model relates to the technical field of building structures, in particular to a suspension structure used for high-rise buildings. Background Art

[0002] The suspended structure in high-rise buildings is a relatively new form of modern architectural design. Compared with traditional high-rise buildings, the suspended structure has the function of increasing the utilization rate of building space and improving the overall image of the building. The deadweight of the suspended layer is transferred to the conversion truss above through the hanging column. At this time, the hanging column is only subjected to tension, which can save a lot of its cross-sectional area and provide more space for the suspended layer. The top conversion truss layer and the top surface layer of the conversion truss do not need to be arranged with load-bearing columns, which can form a large space, providing convenience for some special use needs in high-rise buildings.

[0003] Traditional high-rise buildings often adopt frame structures, frame-shear wall structures and frame core tube structures. The deadweight of the structure is borne by frame columns or shear walls. Frame columns are compression members, and their failure form is usually instability failure, which does not make good use of the strength of steel. The deadweight of the suspended structure is borne by the conversion truss above, and the columns of each floor are tension members, which can make full use of the excellent tensile resistance of high-strength steel, thereby effectively saving the amount of steel used in the structure and achieving the effect of energy saving and emission reduction.

[0004] The size of the existing suspension structure is generally fixed and non-adjustable, and the size cannot be fine-tuned according to actual usage requirements during the construction process, that is, the scope of use is limited.

Four corner columns 11 are provided, and the four corner columns 11 are respectively located at the corners of the rectangle. The corner columns 11 are rectangular steel tube concrete components, and the support columns 12 are square steel tube components. The utility model has the advantages of simple form and clear force. The giant frame composed of the corner column 11 and the conversion truss 2 forms an in-plane lateral force resistance system, and the corner column 11 and the support column 12 form an out-of-plane support structure. When subjected to earthquake action, the inertial force of the suspension mechanism 3 is transmitted to the conversion truss 2 by the suspension column 31, and the horizontal force received by the structure will be borne entirely by the conversion truss 2. The utility model has a higher material utilization rate and a lighter structure. The deadweight of the suspended structure is transferred to the foundation only by four corner columns, so the force on the foundation is more evenly distributed. The use of suspended structures can not only effectively reduce the number of foundations of the structure, but also reduce the uneven settlement of the foundation. The suspended structure can be constructed with prefabricated steel structures, which can greatly reduce dust and noise pollution during construction, and can also effectively simplify the installation process and improve construction efficiency.

The suspension column 31 is a tension member and will not become unstable and fail. It can fully utilize the tensile properties of high-strength steel and improve material utilization. The suspension column 31 is hingedly connected to the frame beam and the conversion truss, which further releases the constraints on the suspension mechanism 3 and effectively reduces its stress level under earthquake action.
