Energy-saving environment-friendly door/window system

Abstract

The invention belongs to the field of building door / window curtain walls, and particularly relates to an energy-saving environment-friendly door / window system. The system comprises a border (1), a mullion (6) and a leaf-hidden window sash (3) arranged therein, wherein an outdoor sealing rubber strip (7) is fixed between the border (1) and the leaf-hidden window sash (3) on the border (1); an indoor sealing rubber strip (2) is fixed between the leaf-hidden window sash (3) and the the border (1) on the leaf-hidden window sash (3); a T-shaped connection glue injection sheet is fixed at the joint between the mullion (6) and the border (1); the T-shaped connection glue injection sheet is clamped and fixed with a notch of the mullion (6); and a glue injection port is formed on the T-shaped connection glue injection sheet. The energy-saving environment-friendly door / window system provided by the invention has good sealing and heat insulation performance, a firm structure and high generality, and can effectively meet the requirements on the lost energy index of the building door / window.

Description

technical field [0001] The invention belongs to the field of building doors, windows and curtain walls, and in particular relates to an energy-saving and environment-friendly door and window system. Background technique [0002] Building energy conservation has been a hot topic in the industry in recent years, and doors, windows and curtain walls, which are part of the building envelope, are particularly important in building energy conservation. According to statistics, building energy consumption has reached 27.6% of the energy consumption of the whole society, and 50% of building energy consumption is related to doors, windows and curtain walls. Therefore, improving the performance of doors, windows and curtain walls and vigorously promoting the use of energy-saving doors, windows and curtain walls are necessary measures to reduce building energy consumption. The concept of doors, windows and curtain walls has been greatly expanded due to the individual requirements of t...

Problems solved by technology

Since the existing exterior window sills usually adopt concrete and stone structures, the linear expansion coefficients of the above two forms of window sills and aluminum alloy windows are quite different, resulting in gaps and leaking points that are likely to occur at the connection between the window sill and the entire window; and The above two forms of window sill structure have poor versatility, low disassembly and assembly efficiency, and there are certain difficulties in matching with the overall style of the building, and it is difficult to meet the architect's requirements for building facade design
