A kind of folding type building external sunshade system window

Abstract

The invention relates to the technical field of building external sunshade, in particular to an unfolded and folded building external sunshade system window. In hot summer, a sunshade plate is unfolded, the sunshade plate freely rotates according to differences of a solar elevation angle and an azimuth angle, solar radiation heat is sufficiently shielded from entering an indoor space in an outdoor space, visible light is not shielded from entering the indoor space, the window is perspective and ventilated, so that indoor temperature is remarkably reduced, the use energy consumption and the use frequency of an air conditioner are effectively reduced, and energy is saved. The sunshade plate on the sunshade system window can freely unfold and rotate according to the requirements of temperature and sunshine and solve the problem that a traditional sunshade window is fixed, heat can be effectively prevented from transmitting inside and outside a building when the requirements of ventilation and light rays are met, a design philosophy of a modern energy-saving building is met, in addition, the sunshade system window is convenient to operate and suitable for popularizing and using, and an angle of the sunshade plate can be adjusted.

Description

technical field [0001] The invention relates to the technical field of building exterior sunshade, in particular to a window of a folding type building exterior sunshade system. Background technique [0002] The architect Le Corbusier once said, "The history of architecture is the history of fighting for light", which shows the importance of architectural sunlight control technology. Statistics show that 95% of the existing buildings in my country are high-energy-consumption buildings, and the energy consumption caused by the window glass on the facade of the building accounts for about 45% of the total energy consumption of the building. If half of the buildings in my country use external shading systems in 2020, More than 100 million tons of quasi-coal can be saved every year. In 2013, the national "Green Building Action Plan" was implemented, and it is imminent and imperative to force the installation of building external shading systems in new buildings and energy-saving...

AI Technical Summary

Problems solved by technology

[0003] Due to the late start of the green building design concept in my country, few engineers specializing in building external sunshade systems, and the introduction of relevant mandatory regulations are passively lagging behind, resulting in the current building external sunshade products are scarce in variety, primitive in function, low in quality, poor in practicability, and generally have fatal flaws. It will be used under the requirements of mandatory regulations, and it will be fooled to pass the test. As a result, due to functional defects, poor handling, fragile parts and difficult repairs, lack of maintenance, and insufficient practicability, the actual frequency of use by users is very low, and the energy-saving effect is in line with the expected goal. The difference is very far, it is actually a waste of invisible resources

The currently used forms of external sunshade for buildings mainly include: LOW-E insulating glass, hard roller shutter type external sunshade, built-in louver insulating glass and fixed suspended panels, etc. The defects of these types of sunshade are as follows: LOW-E insulating glass limits The collection of solar radiant heat in the cold winter season, the hard roller shutter external sunshade limits the demand for lighting, perspective and ventilation in the working environment, the built-in louver hollow glass has obvious heat island effect and non-repairable defects, and the fixed suspended plate can only partially shade. Insufficient effect

[0004] Although there are also rotatable and liftable blinds patents with blades at present, such as a kind of double control arm type liftable external sunshade blinds of Chinese Patent Publication No. 102493751A, the blades in this patent have the functions of rotation and lifting, and the technical principle is the same as that of indoor common lifting venetian blinds. The principle is the same. The core of the technical solution is to realize the lift and rotation of the blades by double control arms. If it is used on glass curtain walls or glass doors and windows with a large unit area, the control flexibility will be limited due to the large volume and dead weight of the double control arms. In addition, its dual control arms can only rely on the four central shafts on both sides to connect with the wall support in the space to ensure free movement, and the stability is not high. In addition, its structural parts are too open and exposed. In harsh weather environments such as snow, wind and sand, the service life is also greatly affected, and the use function is relatively single, without other auxiliary functions such as anti-theft. In short, the patented technical solution still has certain limitations in terms of use environment, control process, and scope of application.
