Precautions for installing a glass balcony railing

May 02, 2021

[China Glass Net] Because the glass fence gives people a transparent and simple effect, if the stained glass is used, it is more artistic, so it is widely used in home decoration. However, if the material is improperly selected or improperly installed, it will easily cause the glass to break and cause a safety accident. Because the guardrail has a decorative effect, it is a force member, which plays a protective role and bears external forces such as pushing. Therefore, the glass used in the glass guard must have sufficient strength. Generally, the guardrail glass should be made of tempered glass or laminated glass. When tempered glass is used, its thickness should not be less than 12mm. Since the glass is a brittle material, the glass must not be in direct contact with the rigid nodes and there should be a resilient material pad between them. When the design adopts the embedded glass guardrail on both sides, the glass should be inserted into the notch of the column to have a gap of more than 3 mm, and the gap is filled with sealant. The depth of the glass embedded slot is not less than 12mm.

When the guardrail replaces the column with glass, a gap of about 8 mm should be left between the glass, and a gap of about 8 mm should be left between the glass and other materials, and the gap should be filled with a sealant. The guardrail base is a key part of the fixed guardrail, and is generally used to form a fixed piece of fixed glass by processing the angle steel and the steel plate. Both sides of the fixing member are fixed with the expansion bolts to the floor or by electric welding and the embedded parts, and are not loose. The glass and the bottom of the fixing member are padded with a rubber support block having a Shore A hardness of 80 to 90. The depth of the glass extending into the fixing member should be greater than 100mm. The glass should extend into the two sides of the fixing member (that is, between the angle steel and the steel plate), leaving a gap of 3 to 5 mm, padding with a neoprene sheet, and clamping the glass. . After the installation is completed and checked, it is safe and firm, and the surface of the guardrail base is covered with decoration. The gap between the cover material and the glass is filled with sealant, and the cover material should not directly contact the glass.
