Description

Technical Field

[0001] The utility model belongs to the technical field of building engineering, and in particular relates to a curtain wall crossbeam reinforcement node. Background Art

[0002] Steel tube structures are often used in the supporting structures of curtain walls.

[0003] The steel structure supporting the curtain wall is mostly made of light square steel tube components, that is, the cross-sectional dimensions of the components are small and the thickness of the steel plate is thin. Such components are easy to process and transport.

[0004] The connection nodes between the supporting steel pipes of the curtain wall usually adopt direct intersection connection, and the steel beam with smaller cross-section is often flush with one side of the steel column with larger cross-section; when the size difference between the steel column and the steel beam is large, this connection should be regarded as a hinged node.

[0005] Although the hinged nodes of the curtain wall steel structure are easy to process, their mechanical properties are poor, and the beams cannot provide support for the steel columns, which is not conducive to the wind and earthquake resistance of the curtain wall support structure.

[0006] The connection between the steel pipes in the prior art adopts a direct intersection method, and the steel beam with a smaller cross-section is flush with one side of the steel column with a larger cross-section. When the sizes of the primary and secondary steel pipes are close, they can be used as rigid connections in the design model.

[0007] When the sizes of the primary and secondary steel pipes differ greatly, if a rigid connection is to be designed, an inner partition aligned with the steel beam flange plate needs to be welded inside the steel column; however, the steel pipes of the curtain wall support structure are smaller in size and the inner partition cannot be welded inside. Therefore, when designing the curtain wall, the intersection nodes of the primary and secondary pipes with a large size difference can only be treated as hinged.

[0008] Shortcomings of current technology:

[0009] When the size of the steel pipe of the steel beam and the steel pipe of the steel column of the curtain wall is greatly different, since it is impossible to weld the inner partition inside the main pipe, the intersection node can only be designed as a hinge. The hinged connection between the main and secondary components is not conducive to the spatial effect of the supporting structure and weakens the safety redundancy of the supporting system.

[0010] In view of the above problems, it is necessary to improve them. Utility Model Content

[0012] In order to achieve the above purpose, the technical solution adopted by the utility model is: a curtain wall beam reinforcement node, including curtain wall beams and curtain wall columns arranged perpendicular to each other; the curtain wall beams and curtain wall columns are square steel pipes; and reinforcement members are installed at the connection between the curtain wall beams and the curtain wall columns.

[0015] As a preferred solution of the utility model, the height of the reinforcement is the same as the clear distance between the webs of the two columns.

[0016] As a preferred solution of the utility model, the length of the reinforcement member is greater than the width of the beam flange plate of the curtain wall beam.

[0017] As a preferred solution of the utility model, the reinforcing web of the reinforcing member is aligned with the beam flange plate of the curtain wall beam.

[0019] As a preferred solution of the utility model, six bolt holes are provided on the upper flange plate and the lower flange plate, and six bolt connection holes are provided on the web of the column.

[0035] A curtain wall crossbeam reinforcement node comprises a curtain wall crossbeam 1 and a curtain wall column 2 which are arranged perpendicular to each other; the curtain wall crossbeam 1 and the curtain wall column 2 are both square steel tubes; the component height of the curtain wall crossbeam 1 is significantly smaller than the component height of the curtain wall column 2; a reinforcement member 3 is assembled at the connection between the curtain wall crossbeam 1 and the curtain wall column 2; the width of the steel tube of the curtain wall column 2 is small, and an inner partition cannot be welded inside; the utility model greatly reduces the construction difficulty by bolting the reinforcement member 3 to the column web 21 and inserting the reinforcement member 3 into the interior of the column.

[0036] The utility model has a simple structure, and the component height of the curtain wall cross beam is obviously smaller than the component height of the curtain wall column; a node structure that is easy to process and install is provided for supporting square steel pipes when the size difference between the steel beam and the steel column is large, and the node structure can meet the requirements of rigid connection, and the structure is easy to implement and does not increase the cost; specifically, at the intersection of the cross beam and the column steel pipe, the curtain wall cross beam 1 is fixed to the side of the curtain wall column 2 by welding.
