Description

Technical Field

[0001] The utility model relates to the technical field of door and window profiles, in particular to a reinforced door and window profile. Background Art

[0002] Door and window profiles generally include aluminum alloy profiles and plastic profiles, which are the main raw materials for modern door and window production. With the improvement of people's living standards, people's requirements for door and window profiles have become higher and higher, such as corrosion resistance, strength, thermal insulation performance, etc. are the focus of people's consideration. As we all know, if the strength of door and window profiles is to be enhanced, the thickness of door and window profiles must be increased, which will inevitably increase the raw material consumption of door and window profiles during production, resulting in a significant increase in its cost and increasing the economic pressure on users; however, door and window profiles do not need high strength in every place when they are used. If high-strength door and window profiles are used in places where the strength requirements are not high, it will inevitably cause a lot of waste and will not be very practical.

[0003] A reinforced door and window profile proposed in the patent with patent authorization announcement number CN201924747U includes a profile body, a cavity is opened in the profile body, and a tearable connecting strip is arranged in the cavity, and the connecting strip is integrally formed with the profile body. When the doors and windows leave the factory, due to thermal expansion and contraction or other external factors, and the fact that the interior of most door and window profiles is hollow, it is easy to cause the door and window profiles to be twisted or bent, which may even affect the installation accuracy during installation in severe cases. A tearable connecting strip is arranged in the cavity to play the role of a reinforcing rib, which can greatly reduce the deformation of the reinforced door and window profile; if it is necessary to increase the bearing strength of the door and window profile, the connecting strip can be torn off, and then a reinforcing frame can be installed in the cavity to greatly increase its strength, which is highly practical.

[0004] When increasing the supporting strength of existing door and window profiles, it is necessary to install a reinforcing frame inside the door and window profile by welding or bolting. Due to the small internal space of the new door and window materials, it is inconvenient to use tools to install the reinforcing frame inside the door and window profile, which affects the installation efficiency.
