Description

TECHNICAL FIELD

[0001] The utility model relates to door and window section bar technical field, concretely to a high strength door and window section bar. BACKGROUND

[0002] As the essential material of home decoration, doors and windows gradually improve in functionality and aesthetics with the development of science and technology. At present, the most widely used door and window material is aluminum alloy. Aluminum alloy can be divided into ordinary aluminum alloy and broken bridge aluminum alloy according to its section characteristics.

[0003] For example, the above-mentioned document with the authorization announcement number CN211692044U sets a trapezoidal aluminum alloy strip in the clamping strip. When the volume of the plastic core section changes greatly due to changes in environmental temperature, the trapezoidal aluminum alloy strip can limit the volume (width) reduction of the plastic core section because its thermal expansion coefficient is lower than that of the plastic core section. This avoids loosening between the clamping strip and the clamping groove and ensures the structural stability of the broken bridge aluminum door and window section. However, the broken bridge door and window section in the above-mentioned document connects the inner section and the outer section through the broken bridge material during use, and the composite clamping points of each section and the broken bridge material are two, which makes the broken bridge material force dispersed to the cross sections of the sections on both sides. The broken bridge material in the above-mentioned document needs to support the sections on both sides at the same time, which results in low strength of the door and window section in the above-mentioned document.
