Description

Technical Field

[0001] The utility model belongs to the technical field of building curtain walls, in particular to a connection structure of a T-shaped steel column and a steel beam. Background Art

[0002] Building curtain wall refers to the non-load-bearing exterior wall enclosure of a building, which is usually composed of panels (glass, metal plates, stone plates, ceramic plates, etc.) and the supporting structure behind them (aluminum beams and columns, steel structures, glass ribs, etc.). Curtain walls can be divided into the following categories based on their uses: building curtain walls, component-type building curtain walls, unitized curtain walls, glass curtain walls, stone curtain walls, metal plate curtain walls, all-glass curtain walls, point-supported glass curtain walls, etc.

[0003] T-shaped steel keels have been widely used in large-span curtain walls because their strength is much higher than that of aluminum profiles. However, the existing connection method of T-shaped steel columns and T-shaped steel beams cannot meet the deformation requirements after welding, and the connection strength is insufficient due to the spring pin connection alone, or the exposed connecting screws affect the appearance, etc., which limits the scope of use of T-shaped steel curtain walls. Utility Model Content

[0027] Specifically, the double-hollow tempered glass 11 is clamped between the aluminum alloy exposed frame column head 8 and the aluminum alloy pressure plate 12 , and the bottom end of the aluminum alloy exposed frame column head 8 vertically penetrates the double-hollow tempered glass 11 .

[0028] Specifically, the aluminum alloy pressing plate 12 is located at a longitudinal vertical position of the aluminum alloy exposed frame column head 8 , and the bottom end of the aluminum alloy exposed frame column head 8 is gap-connected with the top end of the aluminum alloy pressing plate 12 .

[0029] Specifically, an M6 bolt group 13 is provided on the aluminum alloy pressing plate 12 , and the aluminum alloy pressing plate 12 is connected to the aluminum alloy decorative line 15 through the bolt group 13 . The bottom of the aluminum alloy decorative line 15 is fixedly connected with a second aluminum alloy buckle cover 14 .

[0030] Specifically, an aluminum alloy hidden frame column head 16 is provided on the outer side of the T-shaped steel beam body 2, and an EPDM shielding strip 19 is provided on the outer wall of the aluminum alloy hidden frame column head 16 facing away from the T-shaped steel column body 1. An aluminum alloy auxiliary frame 18 is provided inside the EPDM shielding strip 19, and a silicone structural adhesive 21 is provided between the aluminum alloy auxiliary frame 18 and the insulating glass 11.

[0031] Specifically, an aluminum alloy supporting plate 20 is provided on the outer side of the aluminum alloy hidden frame column head 16 .

[0032] Specifically, when the T-steel column body 1 and the T-steel beam body 2 are installed, a noise-proofing rubber pad 22 is provided at the contact point between the T-steel column body 1 and the T-steel beam body 2 , and the noise-proofing rubber pad 22 abuts against the end surface of the T-steel beam body 2 .

[0033] Specifically, all kinds of mounting holes are processed on the T-steel columns 1 and T-steel beams 2 in the factory. When installing on the construction site, the T-steel columns 1 are installed first, and then the T-steel beams 2 are connected to the T-steel columns 1 through spring pins 3. After the installation of the entire surface of the beams and columns is completed and the installation dimensions are re-measured, the 6mm thick hot-dip galvanized steel connecting plates 5 are installed. First, weld the connecting plates 5 to the horizontal cross-intersection of the T-steel columns 1, and then use machine screws 6 to connect the connecting plates 5 to the T-steel beams 2. The holes on the 6mm thick hot-dip galvanized steel connecting plates 5 that are connected to the beams are four horizontal long holes, which can adapt to the thermal expansion and contraction deformation of the beams. The 6mm thick hot-dip galvanized steel connecting plates 5 mainly bear the vertical gravity load and horizontal wind load transferred from the beams to the columns, which greatly enhances the connection strength between the T-steel columns 1 and the T-steel beams 2. The aluminum alloy exposed frame capitals 8 and aluminum alloy concealed frame capitals 16 are pre-notched at the factory to prevent the 6mm-thick hot-dip galvanized steel connecting plates 5 from obstructing the aluminum capitals during on-site installation. After the curtain wall is installed, the spring pins 3 and the 6mm-thick hot-dip galvanized steel connecting plates 5 are concealed by the aluminum profiles, completely obscuring the T-steel curtain wall's appearance.

[0034] How it works

[0035] The connection structure of the T-steel column and the steel beam, the T-steel column 1 and the T-steel beam 2 are the main load-bearing components, and the stability of the structure is ensured by a specific design. The spring pins 3, 6mm thick hot-dip galvanized steel connecting plate 5, etc. are used to achieve a reliable connection between the T-steel column and the T-steel beam. The M8 connecting screws 6 are used to fix the U-steel connecting plate 4 and the T-steel column 1. The T-steel beam 2 is connected to the T-steel column 1 through the spring pins 3 at its left and right ends to achieve the initial positioning of the two. The 6mm thick hot-dip galvanized steel connecting plate 5 is located on the outer side of the connection between the T-steel column 1 and the T-steel beam 2, and is fixed to both sides of the T-steel column 1 through the M8 connecting screws 6 to further strengthen the connection strength. The first aluminum alloy buckle cover 7 is located on both sides of the aluminum alloy exposed frame column head 8 to play a decorative role.

[0036] The aluminum alloy exposed frame column head 8 and the aluminum alloy notch 9 are installed on the outside of the T-shaped steel column 1, which not only provides a decorative effect on the appearance, but also has a functional role. The EPDM strip 10 is installed on the aluminum alloy notch 9 for noise prevention and buffering. The double hollow tempered glass 11 is clamped on the outside of the EPDM strip 10. The aluminum alloy pressure plate 12 is located on the outside of the double hollow tempered glass 11 to fix the glass and provide support. The M6 bolt group 13 and the second aluminum alloy buckle cover 14 fix the position of the aluminum alloy pressure plate 12 and beautify the appearance through the aluminum alloy decorative line 15. The anti-noise rubber pad 22 is arranged between the T-shaped steel column 1 and the T-shaped steel beam 2 to reduce noise. The EPDM shielding strip 19 is used to improve the air tightness and water tightness of the structure and enhance the overall sound insulation effect and weather resistance.
