Description

Technical Field

[0001] This invention belongs to the field of architecture, and in particular relates to a column node structure for inclined column conversion frames. Background Technology

[0002] In recent years, high-rise buildings have developed rapidly, gradually pursuing complex shapes and diverse functions. Many building functions have undergone vertical changes, resulting in vertical components that cannot be directly connected to the foundation.

[0003] When using beam-type transfer, slab-type transfer, and truss-type transfer structures to solve the problem of non-direct access, beam and slab-type transfers often have excessively large cross-sections, resulting in a "strong beam, weak column" structure that is not conducive to seismic resistance. Truss-type transfers can approximate their members as two-force members, which has good integrity. However, due to the complex construction process of the joints between the members, it is difficult to control the quality of the joints, and the arrangement of the members affects the building function of the project. Summary of the Invention

[0004] In view of this, the present invention aims to propose a slanted column conversion frame column node structure to solve the problem that vertical members in the frame structure cannot be directly connected to the foundation and have poor shear resistance when there is a local vertical change.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a sloping column conversion frame column node structure, comprising conversion components and crossbeams, wherein three crossbeams are arranged sequentially from top to bottom, and two conversion components are provided, symmetrically arranged on both sides of all crossbeams; each conversion component includes a first upper column, a vertical middle column, a middle sloping column, a lower column, a second upper column, and a transfer component, wherein the first upper column, the vertical middle column, and the lower column are connected end-to-end sequentially from top to bottom, and the upper end of the first upper column is connected to the uppermost... One end of the crossbeam is connected, the connection between the first upper column and the vertical middle column is connected to one end of the middle crossbeam, the connection between the vertical middle column and the lower column is connected to one end of the lower crossbeam, the second upper column is vertically connected between the upper and middle crossbeams, the connection between the vertical middle column and the lower column is connected to the lower end of the second upper column through an inclined middle column, and the transmission component is set in the second upper column, the vertical middle column, the middle inclined column and the lower column to transfer the vertical force of the second upper column to the lower column.

[0006] Furthermore, the transmission component includes a first vertical part, an inclined part, and a second vertical part, wherein the lower end of the first vertical part is connected to the upper end of the second vertical part through the inclined part.

[0007] Furthermore, the first vertical section is arranged in the same direction within the corresponding second upper column.

[0008] Furthermore, the inclined portions are arranged in the same direction within the corresponding middle-layer inclined columns.

[0009] Furthermore, the second vertical section is arranged in the same direction within the corresponding vertical middle and lower columns.

[0010] Furthermore, the length of the first vertical section is one-third of the length of the second upper column.

[0011] Furthermore, the second vertical section is divided into upper and lower parts along the center line of the corresponding horizontal beam. The length of the upper half of the second vertical section is one-third of the length of the vertical middle-level column, and the length of the lower half of the second vertical section is one-third of the length of the lower-level column.

[0012] Furthermore, the transmission component is made of structural steel.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The structure, through the use of inclined columns and steel sections in the middle layer, can avoid abrupt changes in inter-story shear force and internal forces of structural members, which is beneficial to the seismic resistance of the structure.

[0015] 2. Through the installation of mid-level inclined columns and steel sections, this structure can directly transmit the stress conditions of the vertical members in the frame structure to the foundation. Attached Figure Description

[0018] Upper column 1; Vertical middle column 2; Middle inclined column 3; Lower column 4; Steel section 5; Beam 6; Second upper column 7. Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other, and the described embodiments are only some embodiments of the present invention, not all embodiments.

[0020] Referring to the accompanying drawings, this embodiment describes a sloping column conversion frame column node structure, including conversion components and crossbeams 6. Three crossbeams 6 are arranged sequentially from top to bottom. Two conversion components are symmetrically arranged on both sides of all the crossbeams 6. The conversion components include a first upper-level column 1, a vertical middle-level column 2, a middle-level sloping column 3, a lower-level column 4, a second upper-level column 7, and a transfer component. The first upper-level column 1, the vertical middle-level column 2, and the lower-level column 4 are... The columns are connected end to end from top to bottom. The upper end of the first upper column 1 is connected to one end of the upper horizontal beam. The connection between the first upper column 1 and the vertical middle column 2 is connected to one end of the middle horizontal beam. The connection between the vertical middle column 2 and the lower column 4 is connected to one end of the lower horizontal beam. The second upper column 7 is vertically connected between the upper and middle horizontal beam 6. The connection between the vertical middle column 2 and the lower column 4 is connected to the lower end of the second upper column 7 through an inclined middle column 3. The transmission component is set in the second upper column 7, the vertical middle column 2, the middle inclined column 3 and the lower column 4 to transfer the vertical force of the second upper column 7 to the lower column 4.

[0021] In this embodiment, the steel section 5 includes a first vertical section, an inclined section, and a second vertical section. The lower end of the first vertical section is connected to the upper end of the second vertical section through the inclined section. The first vertical section is arranged in the same direction in the corresponding second upper column 7, the inclined section is arranged in the same direction in the corresponding middle inclined column 3, and the second vertical section is arranged in the same direction in the corresponding vertical middle column 2 and lower column 4.

[0022] In this embodiment, the length of the first vertical section is one-third of the length of the second upper column 7. The second vertical section is divided into upper and lower parts by the center line of the corresponding beam. The length of the upper half of the second vertical section is one-third of the length of the vertical middle column 2, and the length of the lower half of the second vertical section is one-third of the length of the lower column 4, thereby improving seismic resistance.

[0023] In use, in a frame structure, when the bottom structure requires improved aesthetics and other requirements, the columns cannot extend directly to the foundation. In this case, the force of the second upper column 7 is transferred to the lower column 4 through the middle inclined column 3 set in this structure. Combining the advantages of beam transfer and truss transfer, it not only directly transfers the gravity load from the upper structure to the lower column 4 through the middle inclined column 3, but also makes the change in stiffness ratio between the transfer layer and the upper and lower floors very small. Under horizontal seismic action, it can avoid abrupt changes in inter-story shear force and internal force of components, which is conducive to the realization of seismic resistance of the structure.

[0024] Meanwhile, due to the function of steel section 5, it can not only improve the connection between the inclined column and the upper and lower columns and effectively transmit force, but also directly bear the vertical force, while reducing the shear force borne by the transfer beam, avoiding sudden changes in inter-story shear force and internal force of components, which is beneficial to the seismic resistance of the structure.

[0025] The embodiments of the present invention disclosed above are merely illustrative of the invention. These embodiments do not exhaustively describe all details, nor do they limit the invention to the specific implementations described. Many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to better understand and utilize the invention.
