Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to an anti-instability curtain wall connecting beam and a curtain wall connecting method. Background Art

[0002] With the application of steel structure in building structure design, the connection between curtain wall and steel structure is becoming closer. When constructing curtain wall, it is necessary to reserve curtain wall embedded parts on one side of the I-beam. When connecting the curtain wall to the curtain wall embedded parts, the curtain wall will generate lateral tension on the I-beam, which in turn puts forward requirements for the overall stability of the I-beam. In the existing construction method, stiffening ribs are added between the curtain wall embedded parts and the I-beam. This method can only ensure that the lower flange plate of the I-beam does not buckle and fail, but cannot ensure the lateral stability of the I-beam. Summary of the invention

[0003] The purpose of the present invention is to overcome the defects of the prior art and provide an anti-instability curtain wall connecting beam and a curtain wall connecting method. When the curtain wall is connected, after the I-beam is subjected to force on one side, the reaction plate located on the other side of the I-beam provides a reaction force to ensure the lateral stability of the I-beam.

[0004] To achieve the above object, the technical solution adopted by the present invention is an anti-instability curtain wall connecting beam, comprising:

[0005] An I-beam arranged in a horizontal direction, the I-beam being used to connect to the bottom of an existing floor slab;

[0006] A connecting plate for curtain wall connection, the connecting plate is located on one side of the web of the I-beam and is arranged parallel to the web, and the connecting plate is connected between two flange plates of the I-beam;

[0007] A reaction plate is used to prevent the I-beam from becoming unstable due to unilateral force. The reaction plate is located on the other side of the web and is arranged perpendicular to the web. One end of the reaction plate is connected to the web, and the other end extends outwardly by the projection range of the two flange plates to form an extension section, and the extension section is connected to the existing floor slab.

[0008] A further improvement of the anti-instability curtain wall connecting beam of the present invention is that at least two ribs are spaced apart and connected between the connecting plate and the web, at least two of the ribs are spaced apart along the length direction of the web, each of the ribs is disposed perpendicular to the web and the upper and lower ends of each of the ribs are respectively connected to the two flange plates.

[0009] A further improvement of the anti-instability curtain wall connecting beam of the present invention is that the number of the reaction plates is at least two, and the at least two reaction plates are arranged at intervals along the length direction of the web and correspond one-to-one to the at least two ribs.

[0010] A further improvement of the anti-instability curtain wall connecting beam of the present invention is that the upper and lower ends of the reaction plate are respectively connected to the two flange plates.

[0011] A further improvement of the anti-instability curtain wall connecting beam of the present invention is that a support plate is connected between the extension section and the existing floor slab, the support plate is connected to the top of the extension section, and the support plate and the existing floor slab are connected by bolts.

[0012] A curtain wall connection method comprises the following steps:

[0013] Step 1: providing the above-mentioned anti-instability curtain wall connecting beam, and connecting the curtain wall connecting beam to the bottom of the existing floor;

[0014] Step 2: Providing curtain walls and connecting the curtain walls to the connection plates.

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] By providing the reaction plate, the false unilateral pulling force of the curtain wall on the I-beam is offset when the curtain wall is connected, thereby ensuring the lateral stability of the I-beam. BRIEF DESCRIPTION OF THE DRAWINGS
