Description

Technical Field

[0001] This utility model relates to the field of window frame technology, and in particular to an ultra-low energy consumption insulated window subframe. Background Technology

[0002] With the global energy crisis and environmental problems becoming increasingly severe, building energy conservation has become a key area of ​​international concern. In building envelopes, windows, as a crucial link between the interior and exterior, face significant energy loss while providing natural lighting. Especially in cold or hot regions, the thermal insulation performance of windows directly impacts the overall energy consumption of a building.

[0003] Currently, during the installation of building windows, the construction company pre-determines the size of the doors and windows, and the homeowner then selects the appropriate size for installation. However, due to the influence of various factors such as building formwork, pouring, and masonry during civil construction, the standardization of openings cannot be achieved in one go, resulting in installation errors in door and window openings.

[0004] In practical applications, inadequate sealing and anti-corrosion treatment can easily lead to leaks and corrosion, creating safety hazards. Furthermore, the cost is relatively high. Especially now that most residential buildings require external insulation, installing steel subframes cannot solve the "cold bridge" problem in energy-efficient doors and windows with thermal insulation. When air conditioning is turned on indoors, heat can easily escape through leaks in the doors and windows, significantly increasing the power consumption of the air conditioner.

[0005] Therefore, the existing technology needs further improvement. Utility Model Content

[0006] The present invention aims to solve the above problems and provides an ultra-low energy consumption heat-insulating window subframe, including a waterproof and breathable membrane, a fixing strip, a decorative cover plate, a fixing plate, an air-tight membrane, a filling material, and foam strips;

[0007] The waterproof and breathable membrane covers the inner surface of the window frame. There are multiple fixing strips, which are set on the four sides of the window frame. The length of the fixing strips is the same as the width of the window frame. The air-tight membrane is set on the inner side of the decorative cover plate, which is set 15mm outside the window frame keel. The filling material is polyurethane, which is used to fill the gaps inside the window sub-frame. The foam strips are installed at the position of the outer window frame keel.

[0008] Furthermore, the fixing strip is made of anti-corrosion pine wood.

[0009] Preferably, the fixing strip is a pine wood strip with an inclined angle, and the height of the higher end of the fixing strip is the same as the width of the window frame.

[0010] Based on the above technical solution, the fixing strips are respectively set on the four sides of the window frame, one at each corner of the window frame about 200mm away, and the fixing strips are evenly distributed at the remaining positions of the window frame, with the distance between two fixing strips not exceeding 400mm.

[0011] Based on the above technical solution, the air-barrier membrane is set inside the decorative cover plate, with a 20mm allowance at the top and bottom for future use.

[0012] Based on the above technical solution, the fixing plate is installed 10mm from the inside of the window frame, with a width of 15cm, and its width is flush with the vertical keel of the wall.

[0013] Furthermore, the filling material is polyurethane, which requires on-site spraying for insulation.

[0014] More preferably, the air-barrier membrane is adhered to the surface of the filling material.

[0015] This utility model has the following advantages:

[0016] The window subframe provided by this utility model can be installed on-site or prefabricated together with the surface plywood and then assembled on-site. The overall cost of this window subframe is lower. This method has a thermal conductivity of 0.025 W / (m·K) for 60 kg of polyurethane composite and 0.15 W / (m·K), with a composite thermal transfer coefficient of 0.2 W / (m²·K), far lower than the thermal conductivity of rigid fiberglass polyurethane thermally broken window frames with a density of 80 kg of polyurethane (0.038 W / (m·K)) and a thermal transfer coefficient of 1.5 W / (m²·K). The installation process of this utility model's window subframe innovatively utilizes a conversion fixing concept. The window frame is fixed to the wooden frame on the inside of the fiberglass polyurethane thermally broken frame but does not penetrate the wall, resulting in a significant thermal break effect. The wooden frame is fixed to the wall outside the window frame, avoiding the formation of thermal bridges. Attached Figure Description
