Two-layer sunshade glass with fixed type sunshade plate net arranged in middle

Abstract

The invention discloses two-layer sunshade glass with a fixed type sunshade plate net arranged in the middle. A containing cavity is formed between a first outer layer tempered glass body and a second outer layer tempered glass body; a middle layer tempered glass body and the sunshade plate net are arranged in the containing cavity; a U-shaped attached frame with an opening facing outward is further mounted at the edges of the first outer layer tempered glass body and the second outer layer tempered glass body in a clamped mode; and combinations of first unit meshes, second unit meshes, third unit meshes and fourth unit meshes are distributed in the transverse and longitudinal directiona in an array mode to form the plate net. According to the fixed type sunshade glass, the built-in sunshade plate net is provided with light-transmitting holes with special opening angles so that direct light with large energy radiation density can be shielded to the maximum, but outdoor scattering light is allowed to enter, indoor lighting is not affected, the two-layer sunshade glass is suitable for being adopted by lighting roofs and glass curtain walls which are arranged in large area in infrastructures such as airports and stations, later maintenance is not needed, and practicability and convenience are high.

Description

technical field [0001] The invention relates to the sunshade field, in particular to a second-layer sunshade glass and a fixing device of a fixed sunshade net in the middle. Background technique [0002] With the development of my country's construction industry, the construction of a large number of civil buildings, various types of glass lighting roofs (glass roofs, glass skylights), and glass curtain walls have also begun to be widely used in hotels, restaurants, stations, airports, commercial cities, and department stores. , exhibition halls, gymnasiums, museums and hospitals, etc. [0003] Existing glass daylighting roofs and curtain walls are generally composed of glass and metal structures, and the glass surface has the characteristics of strong heat transfer and high thermal transmittance, which has a great impact on indoor thermal conditions; glass daylighting roofs and curtain walls have become architectural The most active and sensitive parts of heat exchange an...

AI Technical Summary

Problems solved by technology

[0004] At present, the specific scheme of sunshade is generally to install temporary sunshade devices such as cloth curtains, bamboo curtains, soft louvers, canvas tents, etc. on the inside of the glass, or by setting permanent sunshade devices such as sunshade boards or sunshade curtains. The sunshade device, which is limited by its own conditions, has the characteristics of limited sunshade performance; as for the permanent sunshade device, it is further divided into horizontal sunshade, vertical sunshade, comprehensive sunshade and baffle sunshade, permanent sunshade The biggest problem with the device is that it cannot well block direct light with high energy radiation density, and does not affect the entry of scattered light, thus affecting indoor lighting
