Detailed ways

In order to further understand the invention content, characteristics and effects of the present utility model, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

Please refer to Fig. 1 , a kind of central exterior sunshade system, including an inner layer of openable glass sash 2, an outer layer of fixed glass window 1, and an inner layer of openable glass sash 2 and the outer layer of fixed glass window 1. Between the sunshade curtain 5, the inner layer can open the glass window 2, the outer fixed glass window 1 and the sunshade curtain 5 are all installed on the window frame, and the upper and lower ends of the outer layer fixed glass window 1 Each is provided with an inward-opening airtight window sash.

In this embodiment, in order to improve the thermal performance of the system and facilitate installation and maintenance, the inner layer of openable glass sash 2 is made of double-layer insulating glass, and the outer layer of fixed glass window 1 is made of ultra-clear safety glass. For the convenience of installation, maintenance and ventilation, the inwardly opening airtight sash arranged at the upper end of the outer fixed glass window 1 is an inwardly opened upper suspension sash 3, and the inwardly opened airtight sash arranged at the lower end of the outer layer fixed glass window 1 is Open and hang down the window sash 4. The openable glass sash 2 of the inner layer is an inner casement sash. For the convenience of operation, the upper end of the sunshade curtain 5 is fixed on the roller shade shaft 7, and both sides are installed in the sunshade curtain side rail 6, and the sunshade curtain side rail 6 is installed on the inner side of the window frame. The curtain shaft 7 is horizontally fixed on the top of the window frame.

Working principle of the utility model:

The sunshade curtain 5 is set in the glass curtain wall or the outer window of the building, so that the outer layer fixed glass window 1 and the inner layer openable glass sash 2 are separately placed on the inner and outer sides of the sunshade curtain 5, wherein the inner layer openable glass sash 2 adopts double The outer layer of fixed glass window 1 is made of ultra-clear safety glass, and the upper and lower ends of the outer layer of fixed glass window 1 are provided with openable inner-opening and airtight sashes, and the inner layer of openable glass sash 2 is installed on the window frame to form a three-layer The structural form of the overall outer eaves window with three glass chambers. In summer: when the weather is very hot, open the upper and lower suspension sash 3 and the lower suspension sash 4 that can be opened up and down on the outer layer, pull up the sunshade 5, and close the inner layer to open the glass sash 2 to form a central window. External sunshade structure. That is, sunlight shines on the sunshade curtain 5, reflects outwards and heats the air, forms a vertical air flow and circulates heat away, and plays the role of external sunshade. Since the central sunshade 5 is fixed on the inner side of the outer layer of the glass window 1, it does not affect the appearance and overall effect of the building facade, and can avoid excessive wind loads on the sunshade by strong winds, and also prevents the central sunshade 5 from being too high. The disadvantage of being easily damaged at high temperatures, and it is also easy to disassemble and repair from the inside. In winter: roll up the sunshade 5 when there is sunlight, so that sunlight can enter the room as much as possible fully, and fully collect and utilize solar energy. When the sunshade 5 is drawn on a cloudy day or at night, the system forms a three-glass three-chamber thermal insulation structure, and its thermal insulation performance can be better than the three-glass two-chamber external thermal insulation window commonly used in four-step energy saving. It completely solves the shortcomings and deficiencies of low-e glass that are often used at home and abroad, and achieves sunshade, heat insulation, heat preservation, energy saving, heat absorption and full use of solar energy.

In the construction projects of new construction, reconstruction and expansion, by adding inner or outer windows and setting the method of central external shading, the performance of the existing building's internal and external shading forms and central shading forms is improved; for existing buildings The glass curtain wall and the sunshade system in the middle, through the modification of the opening method and position of the outer window, the openability of the inner window and the position of the sunshade in the middle, realize the functions of the hot air circulation and heat dissipation in the utility model, and improve the Thermal performance of building glass curtain wall or external window.

The utility model improves the sun-shading performance of the central sun-shading curtain by changing the installation position of the sun-shading curtain. By opening and closing the inner-opening and airtight sash set on the outer fixed glass window and pulling up and rolling up the sunshade in the middle, the dynamic effects of sunshade, heat preservation, heat insulation, heat absorption, and green energy saving are solved. The four seasons, morning and evening, and cloudy and sunny changes correspond to each other, improving and perfecting the thermal performance of building exterior windows and glass curtain walls.

Although the preferred embodiment of the utility model has been described above in conjunction with the accompanying drawings, the utility model is not limited to the above-mentioned specific implementation, and the above-mentioned specific implementation is only illustrative and not restrictive. Under the enlightenment of the utility model, those skilled in the art can also make many forms without departing from the purpose of the utility model and the protection scope of the claims, and these all belong to the protection scope of the utility model.
