Problems solved by technology

[0003] The purpose of the present invention is to solve the above-mentioned problems existing in the existing technology, and provide an aluminum alloy profile for aluminum-wood composite special-shaped doors and windows. When this profile bends a profile with a small arc diameter, there is no need to add support bars and no non-closed cavity will appear. Deformation, profile wrinkling, coating damage, profile fracture, etc.

Embodiment Construction

[0011] like figure 1 Shown in Embodiment 1, this embodiment includes three non-closed cavities 2, 3 and 5 and three connecting strips 1, 4 and 6 respectively matched with the three non-closed cavities 2, 3 and 5. The connecting strips 1 , 4 and 6 are weakly connected to the walls at the openings of the non-closed cavities 2 , 3 and 5 . When bending an arc, add two support strips matching the gap in the gap between the two non-closed cavities 2 and 3. figure 2 It is a schematic diagram of the cross-sectional structure after the weak connecting strips 1, 4 and 6 are torn off after the arc bending in this embodiment is completed.

[0012] like image 3 In the shown embodiment 2, other structures of this embodiment are the same as those of embodiment 1, except that a support bar is added in the gap between the two non-closed cavities 2 and 3 . Figure 4 It is a schematic diagram of the cross-sectional structure after the weak connecting strips 1, 4 and 6 are torn off after the...

Abstract

The invention discloses an aluminum alloy section for aluminum-wood composite abnormal-shaped doors and windows. The aluminum alloy section comprises a plurality of non-closed cavities and connection strips, wherein the number of the connection strips is equal to that of the non-closed cavities and the connection strips are matched with the non-closed cavities; and each connection strip is in an integral structure with and weakly connected with the wall of an opening of each non-closed cavity. The non-closed cavities are closed by the connection strips, the connection strips serve as support pieces when the aluminum alloy section is curved, so that the non-closed cavities have the drawing curve strength which is the same as that of a closed-cavity, and even if the aluminum alloy section is curved into an abnormal-shaped door and window section with the radius less than 1.2 m, the non-closed cavities do not deform, the section is not shrunk or cracked, and a coating is not damaged, etc. The connection strips are torn off after the aluminum alloy section is curved, so that the step of firstly cushioning the support pieces during curving is saved, the section is not discarded as useless, and time and labor are saved. The aluminum alloy section is formed in one-step machining, no test processing is needed, and the reported loss rate is less than 5%.

Description

technical field [0001] The invention belongs to the field of building doors and windows, and relates to an aluminum alloy profile for aluminum-wood composite special-shaped doors and windows. Background technique [0002] Aluminum-wood composite doors and windows are made of aluminum alloy profiles and wood. Wood is the main load-bearing component, and aluminum alloy profiles are auxiliary non-load-bearing components. Since this aluminum alloy profile has a non-closed cavity structure, when it is used as a straight profile or a special-shaped door and window profile with a radius > 1.2 meters, there is no problem with its support strength, and there will be no problems such as wrinkles, coating damage, and profile fracture. When it is used as special-shaped door and window profiles with a radius of less than 1.2 meters, due to its insufficient tensile bending strength and deformation of the non-closed cavity, it is not suitable for matching with the structure of other pro...
