Abstract
Abstract A typical embodiment of the invention provides a structural support for large pressure vessels. Illustratively, the lower surface of a forging on the bottom of the pressure vessel has a keyway slot. A support plate with a mating key that is received within the slot is bolted to the bottom forging. The lower surface of the support plate, moreover, has an arcuate surface that presses against a matching lubricated surface to transmit the entire vertical load to a concrete pedestal that has a means for cooling the concrete structure.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
212 words
A heat-exchanger support comprising a reinforced concrete foundation, anchor bolts embedded within said foundation for transferring vertical loads from the heat exchanger to the foundation, a box spar embedded within said foundation for cooling said reinforced concrete, a base plate resting on said foundation, said base plate having bores formed therein, each of said bores being in alignment with said anchor bolts, said base plate having a generally centrally disposed cylindrical bore that terminates in a base, a lubricated plate member in said cylindrical bore, resting on said base and having a diameter that is smaller than the diameter of said cylindrical bore, said lubricated plate also having a convex surface, an annular shear ring having bores formed in alignment with said respective anchor bolts, said shear ring being superimposed on said base plate and having an inner diameter that is smaller than said lubricated plate diameter in order to overhang a peripheral margin of said lubricated plate, a support block having a concave surface in contact with said lubricated plate convex surface, said support block having a diameter that is greater than said lubricated plate diameter and less than said cylindrical bore diameter in order to partially underlie said shear ring, and means connecting said support block to the heat exchanger.
Claim 2
Dependent Claim
212 words
A heat-exchanger support comprising a reinforced concrete foundation, anchor bolts embedded within said foundation for transferring vertical loads from the heat exchanger to the foundation, a box spar embedded within said foundation for cooling said reinforced concrete, a base plate resting on said foundation, said base plate having bores formed therein, each of said bores being in alignment with said anchor bolts, said base plate having a generally centrally disposed cylindrical bore that terminates in a base, a lubricated plate member in said cylindrical bore, resting on said base and having a diameter that is smaller than the diameter of said cylindrical bore, said lubricated plate also having a convex surface, an annular shear ring having bores formed in alignment with said respective anchor bolts, said shear ring being superimposed on said base plate and having an inner diameter that is smaller than said lubricated plate diameter in order to overhang a peripheral margin of said lubricated plate, a support block having a concave surface in contact with said lubricated plate convex surface, said support block having a diameter that is greater than said lubricated plate diameter and less than said cylindrical bore diameter in order to partially underlie said shear ring, and means connecting said support block to the heat exchanger.
Claim 3
Dependent Claim
24 words
An heat exchanger support according to claim 1 further comprising shear pins depending from said base plate and protruding into said reinforced concrete foundation.
Claim 4
Dependent Claim
35 words
A heat exchanger support according to claim 1 further comprising a shear key interposed between said support block and said means connecting said support block to the heat exchanger in order to absorb shear forces.
Claim 5
Dependent Claim
25 words
A heat exchanger support according to claim 1 further comprising a box spar embedded in said reinforced concrete foundation in order to cool said foundation.
