In order to avoid indoor rainwater flooding, the balcony floor should be 30 ~ 60mm lower than the indoor floor, with a gentle slope in the drainage direction and a water retaining sill at the outer edge to guide the water into the rainwater pipe for discharge. Simple ones include burying galvanized steel pipes or plastic pipes at one or both ends of the balcony for direct drainage, and installing a rain cover at the top of the uppermost balcony.
2, railings and handrails
For safety reasons, a railing or fence is set along the outside of the balcony, about 1 m high, made of wood, brick, reinforced concrete or metal, with handrails on it.
Step 3 decorate
Balcony floor and decorative materials should have the performance of resisting atmospheric and rainwater erosion and preventing pollution. Brick and reinforced concrete balcony surfaces can be plastered, or paved with cylindrical bricks, plastic plates and inlaid with marble and metal plates. The outer edge of the balcony bottom can be plastered with lime mortar within the range of 80 ~ 100 mm, and dripping water can be added. Wooden handrails should be painted for corrosion protection, and metal components and fittings should be rusted.
4. Other facilities
In the balcony where several households are connected together in a residential building, a partition wall or partition should be set between households. Glass windows are installed on the outside of the balcony to form a closed sun room for basking in the sun and keeping warm; Glass windows should be able to be opened and easily disassembled to facilitate ventilation in summer. In order to save energy, balcony panels can also be used as heat collection components.
