Problems solved by technology
[0011] The purpose of the present invention is to solve the problem that "thermal stress deformation" is easy to occur in composite profiles such as "aluminum-plastic composite windows" and "wood-clad aluminum windows" in door and window composite profiles, and at the same time solve the problem caused by the mismatch of the strength of the two materials in the composite profiles. The problem of low service life

Embodiment Construction
[0029] The technical solutions of the present invention will be further specifically described below through the embodiments and in conjunction with the accompanying drawings.
[0030] see figure 1 and figure 2 , the present embodiment adopts the profile made of aluminum alloy as the main structure of the window, refer to the outdoor profile 1, the outdoor aluminum profile 4 of the window sash, and the indoor aluminum profile 7 of the window sash glass, even if the indoor profile 2, the interior middle decorative strip 6, The glass molding strips 3 are all removed, and the basic functions of the window can still be maintained.
[0031] Take the outdoor profile 1 as an example: the outdoor profile 1 has the following key points, one is that there is a dovetail groove 11 on the indoor side, and the other is that there is an inlaid sealing strip device on the lap between the window sash side and the interior middle decorative strip 6 . The combination of outdoor profile 1, sas...

The invention relates to the technical field of building materials, in particular to a solution to thermal stress deformation of a composite window and a structure of the composite window, solving the problems that door and window composite sections such as aluminum-plastic compound windows are easy to deform under thermal stress, and have short service life because two kinds of materials in the composite sections are not matched in strength. In the solution, aluminum alloy sections is taken as major structural materials, and advantages of easy precise shaping and large amount of elastic deformation of the aluminum alloy sections are utilized, indoor sections with heat insulating and decorative functions on the indoor sides of doors and windows are embedded into an aluminum alloy section framework, and the aluminum alloy sections firmly lock the indoor sections in grooves in order to limit transverse displacement and deformation of the indoor sections and prevent the integral structure of the compound window from generating longitudinal deformation under thermal stress. The indoor sections are independent of the major structure, and can be detached and replaced. The invention employs the same aluminum alloy sections, and satisfies different requirements to heat insulating properties in different regions through adjusting the thickness of the indoor sections.
Description
technical field [0001] The invention relates to the technical field of building materials, in particular to a method for solving thermal stress deformation of a composite window and its structure. Background technique [0002] The thermal conductivity of PVC plastic is about 0.14, which is similar to that of wood at 0.12 to 0.3. However, the performance of corrosion resistance and insect resistance such as termites is unmatched by wood. Therefore, it becomes an ideal material for making energy-saving doors and windows. [0003] The composite form of the aluminum-plastic composite window produced by the existing technology is mainly plastic profiles. By rolling the aluminum alloy profiles, the jagged aluminum profile dovetail grooves are bitten into the plastic profiles, and the two profiles are tightly occluded. Move and connect the two tightly together. Because the thermal expansion coefficients of PVC plastic profiles and aluminum alloy profiles are inconsistent, and beca...
