Description

Technical Field

[0001] This utility model belongs to the field of aluminum alloy building structure technology, specifically an aluminum alloy door and window reinforced mullion structure. Background Technology

[0002] A mullion is a dividing structure in doors and windows that separates the frame from the surrounding frame. It divides the door or window into different areas, preventing insufficient glass strength due to an excessively large window sash area. In aluminum alloy door and window structures, mullions are made of aluminum alloy profiles, with different glass sashes installed on each side of the mullion profile.

[0003] If the window sashes of existing aluminum alloy doors and windows are designed to be large, the mullion profiles will bear a heavy load when exposed to strong outdoor wind pressure. If the profiles are not strong enough, they will bend, and the bending stress will be transferred to the glass sash, causing the glass to shatter. Reinforcing the existing door and window mullion profiles to increase their rigidity can prevent this from happening. Summary of the Invention

[0004] To address the aforementioned issues, this utility model provides a reinforced mullion structure for aluminum alloy doors and windows, which is installed and fixed onto the mullion profiles of existing aluminum alloy doors and windows. This structure can increase the strength and rigidity of the mullion, thereby enhancing the stability and wind resistance of the doors and windows.

[0005] The specific solution of this utility model is as follows:

[0006] A reinforced mullion structure for aluminum alloy doors and windows, wherein a reinforcing beam is fixed to the outer surface of the existing mullion, and the reinforcing beam is fastened to the existing mullion with screws.

[0007] The reinforcing beam is placed close to the existing mullion, allowing both to share the load, thereby increasing the stiffness and strength of the existing mullion and reducing deflection. Where screws are used for fastening, the reinforcing beam has machined holes for inserting the screws; where screws are not used, no machined holes are required.

[0008] The cross-section of the reinforcing beam is a hollow cavity, and the foot is in contact with the existing outer wall of the mullion. The threaded part of the screw passes through the inner wall of the cavity, and the end is threadedly fastened to the existing outer wall of the mullion.

[0009] A rubber strip groove is provided at the position where the foot contacts the outer wall of the existing mullion, and a rubber strip is placed in the rubber strip groove.

[0010] The cavity formed between the foot and the existing mullion serves the following purposes: 1. The rubber strip of the foot makes line contact with the outer wall of the existing mullion, forming a sealed cavity with better sealing, preventing rainwater from seeping into the screw and causing it to rust; 2. It increases the cantilever length of the screw tightening, making the screw tightening effect better and less likely to fall off; 3. The inner wall of the mullion reinforcement beam undergoes a certain elastic deformation after the screw is anchored, tightening the threads and preventing the threads from loosening to a certain extent.

[0011] A cover plate groove is provided on the outer side of the central stiffening beam, and the cover plate is fitted and fixed into the cover plate groove. The cover plate can prevent rainwater from entering the internal cavity of the beam, prevent screws from rusting, and improve the appearance.

[0012] The inner wall of the stiffener beam is provided with reinforcing ribs, which further improve the stiffness of the stiffener beam.

[0013] The advantages of this utility model are:

[0014] 1. This utility model structure is specifically designed for strengthening the mullion profiles of aluminum alloy doors and windows, which can increase the strength and rigidity of the mullion, thereby increasing the stability and wind resistance of the doors and windows.

[0015] 2. The reinforcing beam structure of this utility model has good sealing performance, preventing fastener corrosion, and is easy to install; the reinforcing beam can be installed directly using screws. Attached Figure Description
