1, the height of the railing. According to the regulations of residential design code. 1) Balcony railings in low-rise and multi-storey houses should not be less than 1.05m, and the clear height of balcony railings in middle-high and high-rise houses should not be less than 1. 10m. [Article 3.7.3 of Code for Residential Design (GB50096- 1999) stipulates. When the length of the railing in the horizontal section of the stairs is greater than 0.5m, the height of the handrail should not be less than 1.05m, and the clear distance between the vertical bars of the stair railing should not be greater than 0.11m.

2. Balcony railings should be designed to prevent children from climbing. The gap between the railing uprights should not be greater than 0. 1 1m, and the place where the flowerpot is placed must take anti-falling measures. The clear width of the stairwell is greater than 0. 1 1m, and measures must be taken to prevent children from climbing and sliding. [Provisions in Articles 3.7.2 and 4. 1.5 of Code for Residential Design (GB50096- 1999)]

3. The clear distance between the railing and the vertical rod of the handrail should not be greater than 0. 1 1m to prevent children from getting off.

4. The number, specification and location of embedded parts, and the connection nodes between guardrail and embedded parts shall meet the design and specification requirements, and the installation shall be firm and firm.

5. The railing glass bearing horizontal load shall be tempered glass or tempered laminated glass with a nominal thickness of not less than12 mm. ..

6. When the height of one side of the guardrail from the building and the ground is more than 5m, tempered laminated glass should be adopted.

What should I pay attention to when installing glass guardrail?

1. Key points for plane installation of glass guardrail: The glass guardrail must be tempered glass or laminated glass, and the thickness of tempered glass shall not be less than 12mm. The glass cannot directly contact with rigid nodes, and elastic material gaskets shall be provided between them. When designing embedded glass guardrails on both sides, a gap of more than 3mm should be left on both sides of the glass to extend into the groove of the column, and the gap should be filled with glass sealant. The depth of glass embedded in the groove should not be less than12 mm.

2. Installation points of glass guardrail base column: When the guardrail replaces the column with glass, there should be a gap of about 8mm between the glass and between the glass and other materials, and the gap should be filled with sealant. The base of the glass guardrail is the key part of fixing the guardrail in the installation renderings of the glass guardrail. Generally, angle steel needs to be processed and combined into fixed parts to fix the glass. Both sides of the fixing piece are fixed firmly with expansion screws or welded for pretreatment, and are not loose. The bottom of the glass and the fixed parts are padded with rubber bearing seats with hardness of 80 ~ 90. The depth of glass extending into the fixture is more than 1003~6mm, and the glass extends into both sides of the fixture (that is, between angle steel and steel plate).
