Description

Technical Field

[0001] The invention relates to the technical field of glass curtain walls, and in particular to a glass curtain wall supporting system. Background Art

[0002] The existing glass curtain wall support system is generally a steel structure, such as a fish belly truss, a ladder steel truss or a tension rod truss, etc. The front of this support system is generally a frame curtain wall, which is used to fix the glass panel. The structure of the frame curtain wall includes aluminum alloy beams and columns. Since the cross-section of the aluminum alloy column is small, it is generally designed to be subjected to partial tension. The span is generally limited to 4m~5m, and the maximum is not more than 6m. When the building requires a higher elevation and a more transparent facade, considering the compressive stability of the frame curtain wall, a supporting steel structure is generally set at the rear to support the curtain wall columns. Since this method has two layers of columns and two layers of beams, namely aluminum alloy beams, columns and supporting steel structure beams and columns, it affects the transparency required by the building.

[0003] Currently, no effective solution has been proposed for the problems in the related technologies. Summary of the invention

[0004] In view of the above technical problems in the related art, the present invention proposes a glass curtain wall support system, which solves the problem that the current supporting steel structure affects the transparency of the glass curtain wall, breaks through the column span of the conventional curtain wall, and is suitable for glass curtain wall projects with high transparency requirements and large spans (20m~60m or even higher), such as atrium facades, door facades and other important locations of buildings.

[0005] To achieve the above technical objectives, the technical solution of the present invention is implemented as follows:

[0006] A glass curtain wall support system comprises a plurality of steel columns arranged at intervals in horizontal direction, the steel columns extend in vertical direction, the top and bottom of the steel columns are hinged to a main structure, the steel columns are penetrated by a plurality of steel pipes arranged at intervals in vertical direction, the steel pipes extend in horizontal direction, and both ends of the steel pipes are hinged to the main structure.

[0007] Furthermore, the steel pipe includes a plurality of steel pipe units and a plurality of threaded rods, both ends of the steel pipe units are provided with rotatable threaded sleeves, both ends of the threaded rods are respectively threadedly connected to the threaded sleeves, and the threaded rods penetrate the steel columns.

[0008] Furthermore, the steel column is hinged to one end of a plurality of connecting rods arranged at intervals in a vertical direction, and the other end of the connecting rod is hinged to a connecting bridge.

[0009] Furthermore, corresponding connecting ear plates are fixedly connected to the bottom of the steel column and the main structure, and the two corresponding connecting ear plates are hinged together through a pin shaft.

[0010] Furthermore, a steel insert is slidably connected to the upper portion of the steel column, and corresponding connecting ear plates are fixedly connected to the top of the steel insert and the main structure, and the two corresponding connecting ear plates are hinged together through a pin shaft.

[0011] Furthermore, the upper part of the steel column is penetrated by an anti-dropout pin shaft, and the steel insert is provided with an oblong hole that is slidably matched with the anti-dropout pin shaft, and the major axis of the oblong hole is vertically arranged.

[0012] Furthermore, both ends of the steel pipe are hinged to the concrete core tube on the main structure.

[0013] Furthermore, the steel column is made of a square tube, the length of the square tube is 400 mm, the width is 120 mm, the flange thickness is 20 mm, and the web thickness is 16 mm.

[0014] Furthermore, the cross-sectional shape of the steel pipe is circular, the diameter of the steel pipe is 57 mm, and the wall thickness is 8 mm.

[0015] Furthermore, the distance between two upper and lower adjacent connecting rods is 20m.

[0016] The beneficial effects of the present invention are as follows: the steel column has a large span and a relatively small cross-section. Since the aluminum columns of the frame curtain wall are combined and horizontal round steel tubes are used instead of aluminum alloy beams and the steel beams are eliminated, the impact on the transparency of the glass is minimized to the maximum extent. The system is simple in force, and the calculation model has a good degree of conformity with the actual project. It can be applied to important and eye-catching locations with high requirements in buildings such as atrium facades and door facades. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] like Figure 1-5 As shown, a glass curtain wall support system according to an embodiment of the present invention comprises a plurality of steel columns 1 arranged at intervals horizontally, the steel columns 1 extending in a vertical direction, the top and bottom of the steel columns 1 being hinged to a main structure, the steel columns 1 being penetrated by a plurality of steel pipes 2 arranged at intervals vertically, the steel pipes 2 extending in a horizontal direction, and both ends of the steel pipes 2 being hinged to the main structure.

[0028] In a specific embodiment of the present invention, the steel column 1 is hinged to one end of a plurality of connecting rods 6 arranged at intervals in a vertical direction, and the other end of the connecting rod 6 is hinged to a connecting bridge 7 .

[0029] In a specific embodiment of the present invention, corresponding connecting ear plates 8 are fixedly connected to the bottom of the steel column 1 and the main structure, and the two corresponding connecting ear plates 8 are hinged together through a pin shaft 9.

[0030] In a specific embodiment of the present invention, a steel insert 10 is slidably connected to the upper portion of the steel column 1, and corresponding connecting ear plates 8 are fixedly connected to the top of the steel insert 10 and the main structure, and the two corresponding connecting ear plates 8 are hinged together through a pin 9.

[0031] In a specific embodiment of the present invention, the upper portion of the steel column 1 is penetrated by an anti-dropout pin 11, and the steel insert 10 is provided with an oblong hole 12 that slidably cooperates with the anti-dropout pin 11, and the long axis of the oblong hole 12 is vertically arranged.

[0032] In a specific embodiment of the present invention, both ends of the steel pipe 2 are hinged to the concrete core tube on the main structure.

[0033] In a specific embodiment of the present invention, the steel column 1 is made of a square tube, the length of the square tube is 400 mm, the width is 120 mm, the flange thickness is 20 mm, and the web thickness is 16 mm.

[0034] In a specific embodiment of the present invention, the cross-sectional shape of the steel pipe 2 is circular, the diameter of the steel pipe 2 is 57 mm, and the wall thickness is 8 mm.

[0035] In a specific embodiment of the present invention, the distance between two upper and lower adjacent connecting rods 6 is 20m.

[0036] In order to facilitate understanding of the above technical solutions of the present invention, the above technical solutions of the present invention are described in detail below through specific usage methods.

[0037] The glass curtain wall support system of the present invention comprises vertical steel columns 1 and horizontal steel pipes 2. The steel columns 1 are arranged at intervals in the left-right direction, and the steel pipes 2 are arranged in groups, each group of steel pipes 2 is arranged in the up-down direction, and each group of steel pipes 2 comprises two front and rear steel pipes, and the steel pipes 2 all penetrate the steel columns 1, and the rear of the steel columns 1 is connected to the horizontal bridge 7.

[0038] The cross-section of the steel column 1 is rectangular. The lower end of the steel column 1 is load-bearing. The steel column 1 is hinged to the main structure. Two horizontal steel pipes 2 are arranged at every 6m along the upper edge of the steel column 1 as lateral supports for the steel column 1. Both ends of the steel pipe 2 are hinged to the main structure. A bridge 7 (made of a steel beam or concrete beam or other structure) is arranged at every 20m along the upper edge of the steel column 1 for support. The bridge 7 only bears horizontal loads, and the vertical load is transmitted to the lower end of the steel column 1. The top of the steel column 1 is hinged with a single chain rod and only bears horizontal loads. A horizontal steel pipe is also arranged at the top of the steel column 1 as a lateral support. This glass curtain wall support system has a single column without beams. It uses a horizontal steel pipe with a smaller cross-section as a lateral support member of the steel column to ensure the safety and reliability of the system, and minimizes the influence of the structural force-bearing member on the transparency of the glass. It is a revolutionary change to the existing curtain wall support system.

[0039] The steel pipe 2 includes multiple steel pipe units 3 and multiple threaded rods 5. The steel pipe units 3 are connected to the threaded rods 5 through the threaded sleeves 4 thereon. The threaded rods 5 pass through the steel column 1. The steel column 1 has a through hole for the threaded rods 5 to pass through. The outer diameter of the threaded sleeve 4 is larger than the aperture of the through hole, so that the horizontal position of the steel column 1 can be achieved by clamping the steel column 1 between two threaded sleeves 4.

[0040] The main structure includes the main steel structure and the main concrete structure.

[0041] In specific use, a transparent glass curtain wall with a horizontal span of 49.2m and a height of 60m is used as an example for explanation. The top of the glass curtain wall is the main steel structure of the skylight. The cross-sectional dimensions of the steel column 1 are 400×120×16×20mm, of which the flange thickness is 20mm, the web thickness is 16mm, and the cross-sectional dimensions of the steel pipe 2 are φ57×8mm. The steel column 1 adopts the design of lower support, and is connected to the embedded parts of the main concrete structure by connecting the ear plate 8 and the pin 9 to form a hinge node; the top of the steel column 1 is connected to the main steel structure of the skylight through the steel insert 10, the connecting ear plate 8 and the pin 9. Through this one-way plug-in method, the vertical constraint can be released, so that the steel column 1 only bears and transmits horizontal loads. The upper edge of the steel column 1 is connected to the horizontal bridge 7 through a connecting rod 6 every 20m in the vertical direction; after the threaded pull rod 5 passes through the steel column 1, it is connected to the steel pipe unit 3 through the threaded sleeve 4 to form a complete steel pipe 2. Both ends of the steel pipe 2 are connected to the concrete core tube of the main concrete structure, so as to play the role of lateral support of the steel column 1. The steel column 1 supports the horizontal steel pipe 2 in the horizontal load direction to keep it stable, and the horizontal steel pipe 2 is used to support it laterally to prevent lateral instability.

[0042] In summary, with the help of the above technical solution of the present invention, the span is large, the cross-section is small, the force is simple, clear and easy to analyze, which can fully meet the safety requirements of the glass curtain wall. At the same time, there is no need to set up a supporting steel structure, avoiding the problem of structural components caused by the overlap of the supporting steel structure and the frame curtain wall affecting the transparency of the glass curtain wall.

[0043] The above are only preferred embodiments of the present invention and are 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.
