External shading combination window

Abstract

The invention provides an external shading combination window, which includes a combination window frame, a built-in window sash installed on the inner side of the combination window frame and a shutter installed on the outer side of the combination window frame. The shutter includes shutter transverse frames, shutter mullions and louvers enclosed in the shutter transverse frames and the shutter mullions, the shutter can be divided into upper and lower sections which are hinged, the upper section can be stretched out and lifted up at a certain angle, and the lower section can be bent downwards. The advantages of firm and reliable structure and high safety are achieved, and the window can further be used in high-rise buildings; the shaded effect is good, the advantages of the shutter and the structure for shading through stretching out and lifting up are integrated, flat shading is easily realized, the form of shading through stretching out and lifting up can facilitate adjustment of the brightness and line of sight of the external shading combination window, and the advantages of both ventilation and shading are achieved while a built-in window is opened; and burglary prevention can be achieved when the shutter is closed, and the shutter can be used as a fire-fighting escape way when stretching out.

Description

technical field [0001] The invention belongs to the field of building doors and windows, and in particular relates to an external sunshade combined window. Background technique [0002] The sunshade devices of existing building doors and windows are divided into three types: inner sunshade, middle sunshade and outer sunshade: inner sunshade structure, that is, curtains, roller blinds, etc. are installed on the inner surface of glass doors and windows, and has many practical applications; Inner louvers are installed in the middle of the glass interlayer; the outer shading structure, that is, installing vertical louvers on the outer surface of glass doors and windows or setting up protruding sunshade devices, etc., is mainly used in low-rise buildings. Compared with the three kinds of sunshade devices, the outer sunshade can directly block the heat energy of sunlight radiation from the glass window, so the building energy saving of the outer sunshade products is 30%-50% higher...

AI Technical Summary

Problems solved by technology

[0003] However, the reasons for limiting the further popularization of external sunshade products are as follows: 1. Most of the existing external sunshade products are special in structure and cannot be compatible with other building window structures. It is necessary to take the external sunshade structure into consideration during the initial design and construction of the window. It is not conducive to the transformation and addition of external shading of existing windows; for example, the external shading of the vertical louver structure cannot be matched and adapted to windows that open outwards such as casement windows

2. The existing external sunshade products have thin structures, weak frame connections, poor load resistance, and unreliable safety performance, so they cannot be used in high-rise buildings

3. The sunshade effect is not ideal. For example, when the upturned sunshade structure is too large, it cannot block the oblique sunlight from entering the room directly.

4. The vertical sunshade louver structure not only closes the blades for sunshade, but also blocks the exchange of indoor air and outside air to a certain extent, affecting indoor lighting
