Multifunctional composite window auxiliary frame

Abstract

The invention provides a multifunctional composite window auxiliary frame, which comprises glass fiber reinforced plastic sections, main steel linings and connecting steel linings. Each glass fiber reinforced plastic section is provided with two cavities separated from each other by a broken thermal bridge, the two cavities of each glass fiber reinforced plastic section are used for holding the main steel linings and the connecting steel linings, the four sections are mutually perpendicular and are connected end to end so as to be fixed on a wall of a window hole to form the window auxiliary frame, joints of the four sections are sealed by sealing glue, and the main steel linings and the connecting steel linings are placed in the cavities of the sections. Compared with a steel auxiliary frame, the multifunctional composite window auxiliary frame has the advantages that a heat insulation performance and a sound insulation performance are excellent, dimension stability is good, corrosion resistance and aging resistance are good, the multifunctional composite window auxiliary frame is applicable to rainy, wet and coastal areas and chemical places, the service life of the multifunctional composite window auxiliary frame can reach 50 years, and furthermore, the multifunctional composite window auxiliary frame meets key popularization conditions of environment-friendly building materials, and is remarkable in social benefit and environmental benefit.

Description

technical field [0001] The invention relates to a window subframe, in particular to a multifunctional composite window subframe. Background technique [0002] Since the 1980s, building energy conservation and emission reduction has been included in China's important agenda. China has formulated a series of guidelines, policies and regulations on building energy conservation, and issued relevant technical standards and specifications. Statistics show that when the thermal insulation performance and airtightness of doors and windows are poor, the energy consumption of heat transfer loss and osmotic heat loss through building doors and windows, among them, aluminum alloy windows can respectively reach 28% and 20% of building energy consumption, about 50% of building energy consumption. [0003] In the past, in order to meet the needs of building energy conservation, according to the climatic conditions of different regions where the building is located, according to the therm...

Problems solved by technology

[0007] In order to meet the needs of building energy saving, overcome the current steel window sub-frames that are easily deformed, have poor thermal insulation performance, poor air tightness and sound insulation performance, rainwater seepage and air leakage, affect indoor environmental quality, and poor corrosion resistance, so it is not suitable for coastal areas. Disadvantages such as regional use
