1. Architectural design of u-shaped glass
1.1 full u-shaped glass can be used as wall material for interior, exterior wall and roof. Wall has a good light transmission, backlight surface wall diffuse radiation feeling, soft light; Double row installation has better sound insulation and heat insulation effect, and can be reused, is a new type of energy saving and environmental protection materials.
1.2 external walls are generally used in multi-storey buildings. The height of the glass depends on the wind load, the height of the glass from the ground and the connection mode of the glass. Data of German industrial standards 1055 "din-1249" and "din-18056" are provided in page F2 for design selection of multi-storey buildings and high-rise buildings.
1.3 when the length of u-shaped glass wall is greater than 6000 and the height is more than 4500, the stability of the wall shall be calculated and corresponding measures shall be taken. See engineering design for specific practices.
1.4 u-shaped glass is a non-combustible material. If there are special requirements, it shall be designed according to relevant specifications.
1.5 the u-shaped glass adopts eight combinations according to its modeling and architectural functions, as shown in the table below. U-shaped glass can be installed in single or double rows; Vertical, horizontal or slope installation may be required for the design of the building; Ventilation joint or no ventilation joint can be left during installation. This atlas only provides two common combinations of single-row wings facing outwards (or inwards) and double-row wings arranged in pairs at the joints. If other combinations are adopted, it should be noted.
1.6 different surface treatment methods for u-shaped glass include ordinary embossed glass, tempered glass, laminated glass and colored glass. In addition to ordinary embossed glass, the selection of other glass shall be noted.
1.7 when the u-shaped glass is used in the room with high humidity and the temperature difference between inside and outside is large, the problem of dew discharge and droplet on the glass surface should be dealt with well.
1.8 u-shaped glass used for external walls. The length of the glass wall shall be designed according to the individual, but the absolute value of the lower frame material with the deformation of the structure shall not exceed 15.

Each side of the border shall have at least 3 fixed points. The upper and lower frame materials should have 1 fixed point every 400 ~ 600; The size and type of bolts or rivets shall be determined by the manufacturer according to the actual situation of the specific project.
3.2 under the condition of ensuring the size of upper and lower frame orifice, u-shaped glass can be installed with frame orifice composed of steel structure.
