1、U型玻璃的建筑設計
1.1 全U型玻璃作為墻體材料可用于內、外墻及屋面。墻體具有良好的透光性，背光面墻面產(chǎn)生漫放射光感、光線(xiàn)柔和；雙排安裝時(shí)還有較好的隔聲與隔熱效果，并可以重復利用，是一種節能環(huán)保的新型材料。
1.2 外墻一般用于多層建筑，玻璃的高度取決于風(fēng)荷載、玻璃距地高度及玻璃連接方式等。F2頁(yè)中提供了德國工業(yè)標準1055＂DIN-1249＂、＂DIN-18056＂有關(guān)數據，供多層建筑和高層建筑進(jìn)行設計選用。
1.3 U型玻璃墻長(cháng)度大于6000，高度超過(guò)4500時(shí)，應核算墻身的穩定，采取相應措施。具體做法另詳見(jiàn)工程設計。
1.4 U型玻璃屬不燃燒材料，如有特殊要求時(shí)，應按有關(guān)規范進(jìn)行設計。
1.5 U型玻璃按造型及建筑使用功能分別采取八種組合方式，見(jiàn)下表。U型玻璃可單排或雙排安裝；根據建筑設計的需要，可以垂直安裝、水平或坡向安裝；安裝時(shí)留通風(fēng)縫或無(wú)通風(fēng)縫均可。本圖集僅提供了常用的單排翼朝外（或內）和雙排翼在接縫處成對排列兩種組合方式，若采用其他組合方式時(shí)應注明。
1.6 U型玻璃按表面處理方式不同，有普通壓花玻璃、鋼化玻璃、貼膜玻璃、彩色玻璃等，設計選用時(shí)除普通壓花玻璃外，選用其余玻璃應予注明。
1.7 U型玻璃用于濕度較大的房間且室內外溫差較大時(shí)，應處理好玻璃表面露水的排泄及下滴問(wèn)題。
1.8 用于外墻的U型玻璃，玻璃墻的長(cháng)度根據個(gè)體設計，但應滿(mǎn)足下框料隨著(zhù)結構的變形絕對值不能夠超過(guò)15，否則應考慮中間增加固定措施或與廠(chǎng)家協(xié)商配合施工。

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.

3.1 fix the frame in the opening of the building with expansion bolts; Or with bolts, rivets and an existing stressed steel frame anchorage. Borders can be connected at right or oblique angles. 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.
