Description

Technical Field

[0001] The present invention relates to the technical field of urban renewal engineering, and in particular to a protective and reused curtain wall renewal node. Background Art

[0002] Curtain wall renovation is an important part of urban renewal projects. According to different curtain wall forms and owner needs, for existing buildings with both stone curtain walls and glass curtain walls, the glass curtain walls need to be partially updated due to age and damage. The traditional approach is to remove the glass panels and the corresponding keel structure of the glass curtain wall, and then install new glass panels and keel structures. The removal of the glass curtain wall and the corresponding keel structure will affect the stability of the retained curtain wall, and the removal workload is large and the construction cost is high. At the same time, there are great difficulties in the connection between the new glass curtain wall and the retained stone curtain wall. Poor connection will face the risk of water seepage and affect the overall facade effect. Therefore, a protective reuse of the old curtain wall update node is needed to solve the many problems existing in curtain wall renovation. Summary of the invention

[0003] In order to overcome the defects in the prior art, the present 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 the interference to the stone panel, and ensures the overall stability of the curtain wall.

[0004] In order to achieve the above object, the present invention provides a protective and reused curtain wall renewal node, comprising:

[0005] A load-bearing structure and old columns fixedly installed on the load-bearing structure, internal decoration closures and stone panels are respectively provided on both sides of the old columns, characterized in that a new glass curtain wall is fixedly installed on the side of the old columns facing away from the load-bearing structure, a newly added column is fixedly connected between the new glass curtain wall and the old columns, an extension portion extending in a direction close to one 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 newly added column, the extension portion is fixedly connected to the internal decoration closure, an aluminum alloy buckle cover is fixedly installed on the second side of the newly added column, and the aluminum alloy buckle cover is respectively sealed and connected to the new glass curtain wall and the stone panel.

[0006] Preferably, connecting bolts for cooperating with connecting nuts to fix the old column and the newly added column are inserted into the old column and the newly added column.

[0007] Preferably, the second side of the newly added column is fixedly connected to an aluminum alloy pressure plate by a first bolt, and the aluminum alloy buckle cover is fixedly mounted on the side of the aluminum alloy pressure plate facing away from the newly added column.

[0008] Preferably, a transverse frame is fixedly connected to the back of the new glass curtain wall, and second bolts for fixedly connecting the newly added columns to the transverse frame are inserted into the transverse frame and the newly added columns.

[0009] Preferably, sealant is filled between the new glass curtain wall and the newly added columns, between the new glass curtain wall and the aluminum alloy buckle cover, and between the aluminum alloy buckle cover and the stone panel.

[0010] Due to the adoption of the above technical solution, the present invention has the following beneficial effects:

[0011] 1) Economic efficiency and reduced construction costs: The amount of building demolition is reduced, saving demolition costs.

[0012] 2) Reduce interference with the stability of the curtain wall in the reused area: By using new columns to connect the curtain wall keels in the reused area with 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.

[0013] 3) Strong adaptability and good airtightness: The newly made curtain wall aluminum alloy buckle cover presses the reused curtain wall, which can reduce the gap width between the newly added columns and the curtain wall in the reused area caused by the size deviation of the original building curtain wall, and improve the airtightness of the facade. At the same time, the extension of the newly added column can cover the original column, playing the role of interior renovation. BRIEF DESCRIPTION OF THE DRAWINGS
