Technical Field

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

[0002] In the current building materials market, the main materials for door and window profiles are plastic, aluminum alloy and their composite materials. Plastic profiles are favored for their lightness and easy processing, but they are insufficient in strength and bending resistance, are prone to deformation, and are prone to aging in outdoor environments. Aluminum alloy profiles are another popular choice for their durability, but the cost of aluminum alloy profiles is relatively high, and they have a large heat transfer coefficient, which will have an adverse effect on the maintenance of indoor temperature.

[0003] Based on the above situation, plastic profiles have low strength and poor weather resistance, while aluminum alloy profiles are strong and durable but have strong thermal conductivity, which is not conducive to maintaining indoor temperature. Therefore, this application provides steel-plastic composite door and window profiles. Utility Model Content

[0004] In order to address the deficiencies in the above-mentioned prior art, the purpose of the utility model is to provide a steel-plastic composite door and window profile, which combines the advantages of plastic profiles and steel profiles to ensure the stability and safety of the product when used in severe weather, and on this basis, realizes the function of thermal insulation to improve indoor comfort.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A steel-plastic composite door and window profile is provided, comprising a fan body and a frame body, wherein the fan body and the frame body are hingedly connected by hinges, and a rubber strip is arranged at the abutment between the fan body and the frame body. The fan body comprises a first plastic profile and a first steel profile, and the first plastic profile and the first steel profile are respectively embedded and installed on both sides of the first shaping profile.

[0007] Furthermore, the frame includes a second plastic profile and a second steel profile, which are respectively embedded and installed on both sides of the second shaping profile; and rubber strips are respectively provided at the abutment points of the first plastic profile and the second plastic profile and at the abutment points of the first steel profile and the second steel profile.

[0008] Furthermore, the fan body is connected to glass, a rubber strip is provided at the joint between the fan body and the glass on the indoor side, and a sealant and double-sided tape are provided at the joint between the fan body and the glass on the outdoor side.

[0009] Furthermore, a cavity is provided between the fan body and the side edge of the glass, a glass pad is installed in the cavity, and two sides of the glass pad are respectively in contact with the fan body and the glass.

[0010] Furthermore, the fan body and the frame body are respectively provided with reinforced steel at inner positions corresponding to the hinges, and the fasteners penetrate the hinges and are engaged with the reinforced steel by screw threads.

[0011] Furthermore, the hinge is made of alloy steel precision casting.

[0012] Furthermore, the fastener is a self-tapping screw.

[0013] Furthermore, the first shaping profile and the second shaping profile are both made of aluminum alloy.

[0014] Furthermore, the rubber strip is an EPDM rubber strip.

[0015] Furthermore, the sealant is weather-resistant silicone sealant.

[0016] Compared with the prior art, the beneficial effects of the utility model are:
