Support bracket

The main load carried by the brackets will be the weight of the vessel and contents in addition the bracket must be designed to resist the load due to any bending moment due to wind, or other loads. If the bending moment is likely to be significant skirt supports should be considered in preference to bracket supports. 

The brackets, and supporting steel work, can be designed using the usual methods for structural steelwork. Suitable methods are given by Bednar (1986) and Moss (2003). 

A quick method for sizing vessel reinforcing rings (backing plates) for bracket supports is given by Mahajan (1977). 

Lc = the characteristic dimension of bracket (depth), mm, tc = thickness of plate, mm.

Make a preliminary mechanical design for the vertical thermosyphon reboiler for which the thermal design was done as Example 12.9 in Chapter 12. The inlet liquid nozzle and the steam connections will be 50 mm inside diameter. Flat plate end closures will be used on both headers. The reboiler will be hung from four bracket supports, positioned 0.5 m down from the top tube plate. The shell and tubes will be of semi-killed carbon steel. 

Special Scaffolds There are many kinds of specialty scaffolds. Ladder jacks attach to straight or extension ladders. Two ladders with ladder jacks will support planks between them. Users nail roofing brackets to roofs with steep slopes or suspend them with ropes and proper anchors. The brackets support planks between them that workers stand on. After roofing is complete, users remove the planks and brackets. 

Tubing is hung on a bracket support system called a hanger . Hanger seals are very large, square-cut pieces of rubber used to prevent fluid or gas escaping at the point of attachment.
