Description

Technical Field

[0001] The utility model relates to the technical field of large-span glass curtain walls, in particular to a double-supported swing column system of a large-span glass curtain wall. Background Art

[0002] There are two ways to fix the top of the steel frame large-span glass curtain wall according to the displacement of the upper support. When there is no additional displacement of the upper support, we can use ordinary hinged swivel parts to fix it. When the upper support has additional displacement due to the roof structure, we need to use a two-link connection method to release the additional displacement (sway column system). However, when the wind load is large or the span is large, the single-support connection method cannot meet the requirements without increasing the size of the column.

[0003] There is currently no effective solution to the above problems. Utility Model Content

[0005] In order to achieve the above technical purpose, the technical solution of the utility model is implemented as follows:

[0006] A double-supported swing column system for a large-span glass curtain wall comprises a column, wherein the column is fixedly connected to the glass curtain wall, the bottom end of the column is movably connected to a horizontal steel frame through a bottom fulcrum, the middle part of the column is movably connected to a vertical steel frame through an intermediate fulcrum, and the top end of the column is movably connected to a roof structure through a top fulcrum;

[0007] The intermediate fulcrum includes a steel member fixedly connected to the vertical steel frame, and support members fixedly connected to the steel member are provided at both ends of the steel member. Ear plates are provided on both sides of the support member close to the column. The ear plates are movably connected to the steel plate fixedly connected to the middle part of the column through pin shaft 2.

[0008] Furthermore, the bottom fulcrum includes an ear plate 1 symmetrically arranged on the upper part of the transverse steel frame, and the ear plate 1 is movably connected to the bottom end of the column.

[0009] Furthermore, the ear plate 1 is movably connected to the bottom end of the column through the bidirectional ball joint 1 and the pin 1.

[0010] Furthermore, the top fulcrum includes ear plate three symmetrically arranged at the bottom of the roof structure, the ear plate three is movably connected to one end of a connecting rod, and the other end of the connecting rod is movably connected to ear plate four symmetrically fixedly connected to the top of the column.

[0011] Furthermore, the ear plate three is movably connected to one end of the connecting rod through a multi-directional ball joint and a pin shaft three.

[0012] Furthermore, the other end of the connecting rod is movably connected to a symmetrical ear plate four fixedly connected to the top of the column through a two-way ball joint two and a pin four.

[0013] Beneficial effects of the utility model: The utility model adopts a double-support + rocking column structural system. The bottom fulcrum can bear weight, resist wind and release additional angular displacement; the middle fulcrum can resist wind and release additional angular displacement and two-way linear displacement; the top fulcrum can resist wind and release angular displacement and three-way linear displacement.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0024] like Figure 1 As shown, a double-supported swing column system of a large-span glass curtain wall according to an embodiment of the utility model comprises a column 1, wherein the column 1 is fixedly connected to a glass curtain wall 2, the bottom end of the column 1 is movably connected to a horizontal steel frame 4 via a bottom fulcrum 3, the middle part of the column 1 is movably connected to a vertical steel frame 6 via an intermediate fulcrum 5, and the top end of the column 1 is movably connected to a roof structure 8 via a top fulcrum 7;

[0025] like Figure 6-7 As shown, the middle fulcrum 5 includes a steel member 501 fixedly connected to the vertical steel frame 6, and support members 502 fixedly connected thereto are provided at both ends of the steel member 501, and ear plates 503 are provided on both sides of the support member 502 close to the column 1. The ear plates 503 are movably connected to a steel plate 505 fixedly connected to the middle part of the column 1 through a pin 504, and a circular hole 506 is provided in the middle of the steel plate 505, and the cross-sectional area of ​​the pin 504 is smaller than the circular area of ​​the circular hole 506.

[0026] like Figure 2-3 As shown, the bottom fulcrum 3 includes an ear plate 301 symmetrically arranged on the upper part of the transverse steel frame 4, and the ear plate 301 is movably connected to the bottom end of the column 1. The ear plate 301 is movably connected to the bottom end of the column 1 through the two-way ball joint 302 and the pin 303.

[0027] like Figure 4-5 As shown, the top fulcrum 7 includes an ear plate three 701 symmetrically arranged at the bottom of the roof structure 8, and the ear plate three 701 is movably connected to one end of a connecting rod 702, and the other end of the connecting rod 702 is movably connected to a symmetrical ear plate four 703 fixedly connected to the top of the column 1.

[0028] In the embodiment, the ear plate three 701 is movably connected to one end of the connecting rod 702 through a multi-directional ball joint 704 and a pin shaft three 705 .

[0029] In the embodiment, the other end of the connecting rod 702 is movably connected to a symmetrical ear plate 4 703 fixedly connected to the top of the column 1 through a two-way ball joint 2 706 and a pin 4 707 .

[0030] In order to facilitate understanding of the above technical solution of the present invention, the above technical solution of the present invention is described in detail below through specific usage.

[0031] In specific use, according to the double-supported swing column system of a large-span glass curtain wall described in the utility model, the column span in this embodiment is 25 meters, the column grid is 2 meters, the wind load is 4KPa, the roof is a steel grid structure, and the upper support point has a linear displacement of 50 mm in three directions.

[0032] The bottom of the column is connected to the ear plate through a two-way ball joint and a pin, and can be rotated to achieve wind resistance, load-bearing, and release the additional angular displacement caused by the movement of the roof structure.

[0033] The top fulcrum is connected by a connecting rod, one end of which is connected to the column and the other end is connected to the roof structure. The end connected to the column adopts a two-way ball joint to release the angular displacement of the roof structure, and a gap is left with the ear plates on both sides to release the left and right linear displacement caused by the roof structure; the other end is connected to the roof structure and adopts a multi-directional ball joint to release the angular displacement of the roof structure; the upper and lower linear displacements of the roof structure are released by the rotation of the ball joint to drive the column to swing back and forth.

[0034] The middle fulcrum adopts a pin shaft + a large circular hole. The large circular hole can release the additional linear displacement and angular displacement of the roof structure. Since the column needs to swing back and forth to release the upper and lower linear displacement of the roof structure, a large circular hole is adopted. When the deflection of the column reaches the limit value, the pin shaft contacts the inner wall of the large circular hole and starts to resist wind pressure. At this time, the force form of the column becomes a double-pivot form. When the deflection of the column is less than the limit value, the pin shaft breaks away from the inner wall of the large circular hole, and the force form of the column becomes an ordinary simply supported beam.

[0035] In summary, with the help of the above technical solution of the utility model, a double-support + rocking column structural system is adopted. The bottom fulcrum can bear weight, resist wind and release additional angular displacement; the middle fulcrum can resist wind and release additional angular displacement and two-way linear displacement; the top fulcrum can resist wind and release angular displacement and three-way linear displacement. The middle fulcrum adopts a large circular hole + pin shaft fixing method. When the roof displacement brings angular displacement and linear displacement to the upper fulcrum attachment, the entire column will swing within a certain range to release the displacement. In this case, our middle fulcrum will only play a restraining role when the column swings to a certain position. The utility model can effectively reduce the cross-sectional size of the column under high wind pressure, and at the same time release the angular displacement and linear displacement brought by the roof structure, ensuring economy and optimal effect while ensuring functionality.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
