High-efficiency, low-cost and energy-saving building door and window structure

Abstract

The invention provides a high-efficiency, low-cost and energy-saving building door and window structure. The high-efficiency, low-cost and energy-saving building door and window structure comprises a window frame and a window sash, wherein the window frame is provided with a fixed window fixedly mounted on one side of a middle column and a window sash mounting frame formed on the other side of the middle column, the window sash is hinged to the interior of the window sash mounting frame of the window frame, and four edges of the window frame are embedded into the inner side of a concrete wall body at a window frame mounting opening of the concrete wall body from the indoor side. According to the high-efficiency, low-cost and energy-saving building door and window structure, a heat insulation principle different from that of traditional broken bridge aluminum is achieved, a broken-bridge-free and extremely-simple structure and a high-efficiency production mode are adopted, and a final product reaches energy-saving technical indicators including a heat preservation coefficient of 1.1, wind pressure resistance strength of level 9, air tightness of level 8, water tightness of level 6, and sound insulation of 30-40 decibels, and meets or exceeds the energy-saving standard of an existing product in China. The high-efficiency, low-cost and energy-saving building door and window structure also meets the requirements of energy conservation and environmental protection, and belongs to recyclable environment-friendly products.

Description

technical field [0001] The invention relates to a building door and window. In particular, it relates to a high-efficiency, low-cost, energy-saving building door and window structure. Background technique [0002] At present, 95% of existing buildings in China are still high-energy-consumption buildings, and most provinces still use single-glass windows. my country's coal accounts for 70% of energy and power generation. Coal is transported from north to south, gas from west to east, and even across the ocean. As a result, nearly half of it is wasted on building windows. The energy saving of windows accounts for more than 40% of the building energy saving. Therefore, the development of energy and building energy saving and the reduction of coal consumption should be carried out at the same time. At present, most of the windows in the country are still old-fashioned doors and windows with a K value of more than 6, and the energy saving performance is very poor. In the past ...

AI Technical Summary

Problems solved by technology

This improvement method is costly and unsatisfactory, and the product price is still high

The current engineering price of windows with a K value of 1.1 is more than 2,000 yuan / ㎡, which is too high to be widely promoted, and the product has a short shelf life
