SUPPORT OF COLUMN

Glass plants and pipeline should be supported correctly. To prevent inducing undesirable stresses in the glass,
support should be rigid. When supported, glass should be in compression.

Generally, glass plant and equipment are supported in a rectangular tubular structure. This structure is formed of galvanized mild steel tubing with the cast iron fittings which are described in this catalogue. This type of following rules should be followed while supporting a glass unit in a tubular structure.

  1. The structure must be rigid. To give lateral support it must be braced back to the nearest wall or any rigid feature.
  2. All glass columns are builds up from a fixed point on which whole weight of the column should be taken. If total load exceeds the permissible limits, counter balance supports should be used to relieve excessive weight.
  3. With change in temperature, glass column and tubular structure expands at different rate. Therefore glass unit must be free for vertical movement above the fixed point. Hence, above the fixed point, guide supports should be used to give lateral support.
