U型玻璃的端面和平面应无锯齿状缺口或裂纹。

各独立的U型玻璃构件应支撑在具有均匀弹性的衬垫上。

玻璃与临近的金属件、混凝土和砂浆结构之间不能有硬性接触。

在U型玻璃的上端与更高处的建筑物件（如过梁、大梁、屋面板等）之间必须留有缝隙。

U型玻璃上端与临近的上部结构之间的空气缝隙不应小于25mm，以应付其变形，便于安装更换。

必须用弹性密封材料填充U型玻璃之间的纵缝。

密封材料，通常有二组分的聚硫塑料、硅铜胶、柔性聚氯乙烯型材等，用于U型玻璃与固定件、U形玻璃条之间的密封。

圆绳，用于U型玻璃与边框之间的密封。

条形衬垫、柔性聚氯乙烯型材、浸过沥青的条带、硬泡沫塑料等，用作U型玻璃与边框之间的胀缝和滑缝。

膨胀螺栓，用于固定边框

The end and surface of the U-shaped glass shall have no jagged gaps or cracks.
Each independent U-shaped glass member shall be supported on a liner with uniform elasticity.
There is no hard contact between the glass and the adjacent metal parts, concrete and mortar structures.
There must be a gap between the upper end of U-shaped glass and higher building objects(such as beams, beams, house panels, etc.).
The air gap between the upper end of the U-shaped glass and the adjacent superstructure should not be less than 25mm to cope with its deformation and facilitate installation and replacement.
The longitudinal seam between U-shaped glass shall be filled with elastic sealing material.
Sealed materials, usually two-component polysulfur plastics, Silicon copper glue, flexible polyvinyl chloride profiles, etc., are used for sealing between U-glass and fixed parts and U-shaped glass bars.
Round rope, used for sealing between U-shaped glass and the border.
Bar liners, flexible PVC profiles, tarmac strips, hard foams, etc., are used as bulging and sliding seams between U-glass and borders.
Expansion bolt for fixing the border
