  1. R The Transparent Specialist STRUCTURE AND SUPPORTS Glass plants are normally supported in a tubularstructure formed of galvanised steel tubes or mild steel with epoxy coated or stainless steel 304 & 316. This type of structure is proved robust and flexible over many years. 56

  2. R STRUCTURE AND SUPPORTS SUPPORT OF COLUMN The Transparent Specialist 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 galvenised mild steel tubing with the cast iron fittings which are described in this catalogue. This type of structure provides enough flexibility for future modifications and is strong enough to support a glass unit. GUIDE SUPPORT BRACING IN WALL 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 build up from a fixed point on which whole weight of the column should be taken. GUIDE SUPPORT 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, guides supports should be used to give lateral support. BASE SUPPORT FOUNDATION STRUCTURE TUBES, GALVANISED Tube size For forming the structure,"B" class galvanised tubes, Mild Steel with Epoxy Coated, Stainless Steel 304 & 316 are used in size of 1/2", 1", 1.1/4", 1.1/2" and 2". Cut tubes are available in required length to form a standard size structure. Cut tubes are provided with rubber plug at both the ends.

  3. R STRUCTURE AND SUPPORTS The Transparent Specialist STRUCTURE FITTINGS NB Following structure fittings are available to use with galvanised tubes in order to form a tubular structure for a glass plant. These fittings are made of cast iron. Also available in Stainless Steel 304 & 316 and are suitable to the galvanised tubes described earlier. d These slidable fittings are provided with grub screws to fix it at required position on a galvanised tube. These fittings are specially made to construct a tubular structure which provides enough flexibility for future modifications without involving any hammering and welding.

  7. R STRUCTURE AND SUPPORTS The Transparent Specialist GROUTING OF BASE 1. Take one Cast Iron BASE and four foundation Bolts, each with 2 nuts. 2. Fit the bolts in BASE so that base is raised upto 150mm from head of bolts. 3. Put this assembly on the floor and prepare a rough surface for proper bonding of grouting. 4. Make a concrete block over the bolts of about 200 x 200 mm upto the base of BASE i.e. 150mm high. 5. Prepare separate block for each BASE instead of making one big common block. For all BASES. 62

  8. R STRUCTURE AND SUPPORTS The Transparent Specialist ASSEMBLING OF STRUCTURE Mark the position of required fittings on all the Vertical tubes, slide them in correct sequence and lightly Tighten. Assemble one side frame of the structure by adding the cross tubes between two vertical tubes. 1 2 Assemble other side frame of the structure by adding the cross tubes between other two vertical tubes. Build up the cross tubes in one side frame and Tighten lightly. 3 4 Add the other side frame on it and tighten all the fittings firmly. Hoist the structure and brace it to some existing rigid feature. 5 6 Grout the foundation bolts and fix the structure bases with that. Adjust bracing to obtain a correct plumb in Structure. 7 8 Assemble the support tubes at their positions. Adjust the horizonatal frames in correct level. 9 10 63
