Description

Technical Field

[0001] This invention relates to the field of urban renewal engineering technology, and in particular to a protective and reusable curtain wall renewal node. Background Technology

[0002] Curtain wall renovation is a crucial part of urban renewal projects. Depending on the curtain wall type and the owner's needs, for existing buildings where stone and glass curtain walls are connected, the glass curtain walls often require partial renovation due to age and damage. The traditional approach involves removing the glass panels and corresponding keel structure of the glass curtain wall, and then installing new glass panels and keel structure. Removing the glass curtain wall and its corresponding keel structure affects the stability of the existing curtain wall, and the demolition work is extensive and costly. At the same time, the connection between the new glass curtain wall and the existing stone curtain wall presents significant challenges. Poor connection can lead to water leakage and affect the overall facade effect. Therefore, a protective and reusable method for renovating old curtain wall nodes is needed to solve the many problems in curtain wall renovation. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, this invention provides a protective reused curtain wall renewal node, which improves the connection performance between the new glass curtain wall and the protective reused stone panel, reduces interference with the stone panel, and ensures the overall stability of the curtain wall.

[0004] A load-bearing structure and an old column fixedly installed on the load-bearing structure, wherein the old column has an interior finishing edge and a stone panel on both sides, characterized in that a new glass curtain wall is fixedly installed on the side of the old column facing away from the load-bearing structure, and a new column is fixedly connected between the new glass curtain wall and the old column, wherein an extension portion extending towards the side of the load-bearing structure and used to cover the side of the old column is fixedly connected to the first side of the new column, the extension portion being fixedly connected to the interior finishing edge, an aluminum alloy buckle cover being fixedly installed on the second side of the new column, and the aluminum alloy buckle cover being sealed to the new glass curtain wall and the stone panel respectively, and an aluminum alloy pressure plate being fixedly connected to the second side of the new column by a first bolt, the aluminum alloy buckle cover being fixedly installed on the side of the aluminum alloy pressure plate facing away from the new column.

[0005] Both the old and new columns are fitted with connecting bolts for securing the old and new columns together with connecting nuts.

[0006] A horizontal frame is fixedly connected to the back of the new glass curtain wall, and a second bolt is inserted into the horizontal frame and the newly added column to fix the newly added column to the horizontal frame.

[0007] The new glass curtain wall is filled with sealant between itself and the newly added column, between itself and the aluminum alloy cover, and between the aluminum alloy cover and the stone panel.

[0008] By adopting the above technical solution, the present invention has the following beneficial effects:

[0009] 1) Reduced economic efficiency and construction costs: Reduced building demolition volume and saved demolition costs.

[0010] 2) Reduce interference with the stability of the curtain wall in the reused area: By using new columns to connect the curtain wall keel in the reused area to the newly added curtain wall, while retaining the old columns of the original glass curtain wall, the structural stability of the curtain wall in the reused area is improved.

[0011] 3) Strong adaptability and good airtightness: The aluminum alloy cover of the new curtain wall presses down on the old curtain wall, which can reduce the gap width between the newly added columns and the old curtain wall due to the dimensional deviation of the original building curtain wall, improve the airtightness of the facade, and at the same time, the extension of the newly added columns can cover the original columns, which plays the role of interior renovation.

Detailed Implementation

[0017] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0018] Please see Figure 1 and Figure 2 As shown, this embodiment of the invention provides a protective reuse of old curtain wall renovation node, including a load-bearing structure 12 and an old column 1 fixedly installed on the load-bearing structure 12. The old column 1 has an interior decoration trim 6 and a stone panel 4 on both sides respectively. A new glass curtain wall 5 is fixedly installed on the side of the old column 1 facing away from the load-bearing structure 12. A new column 2 is fixedly connected between the new glass curtain wall 5 and the old column 1. An extension 21 is fixedly connected to the first side of the new column 2, extending towards the side closer to the load-bearing structure 12 and used to cover the side of the old column 1. The extension 21 is fixedly connected to the interior decoration trim 6. An aluminum alloy buckle 3 is fixedly installed on the second side of the new column 2, and the aluminum alloy buckle 3 is sealed to the new glass curtain wall 5 and the stone panel 4 respectively. By setting the extension 21 on the new column 2, the L-shaped shape can cover the old column 1, which plays a role in interior renovation.

[0019] Furthermore, in this embodiment, connecting bolts 7 are inserted on the old column 1 and the newly added column 2 to fix the old column 1 and the newly added column 2 together with connecting nuts 8. Preferably, an aluminum alloy pressure plate 13 is fixedly connected to the second side of the newly added column 2 by a first bolt 10, and an aluminum alloy cover 3 is fixedly installed on the side of the aluminum alloy pressure plate 13 facing away from the newly added column 2. By setting the aluminum alloy cover 3 to press down on the old curtain wall, the gap width between the newly added column 2 and the curtain wall of the reused area caused by the dimensional deviation of the original building curtain wall can be reduced, thereby improving the airtightness of the facade.

[0020] Furthermore, a horizontal frame 9 is fixedly connected to the back of the new glass curtain wall 5, and a second bolt 14 is inserted into the horizontal frame 9 and the newly added column 2 to fix the newly added column 2 to the horizontal frame 9. Preferably, sealant 11 is filled between the new glass curtain wall 5 and the newly added column 2, between the new glass curtain wall 5 and the aluminum alloy cover 3, and between the aluminum alloy cover 3 and the stone panel 4.
