A structural mounting for a heavy machinery with rotating parts being supported between a foundation surface and the heavy machinery is disclosed which includes an impermeable foundation surface supporting spaced apart columns of epoxy or similar grouting material with epoxy or similar grouting material chocks extending from the plurality of columns to the support frame of the heavy machinery or engine which provide a non-adherent support between the columns and the engine mounting frame. The columns surround but do not adhere to anchor bolts secured in the foundation. The epoxy chocks likewise do not adhere to the anchor bolts. The anchor bolts are protected with a shroud or wrapping of suitable material whereby post tensioning of the anchor bolts will not cause the columns or chocks to crack or fracture. Leveling screws threadedly engaged through the mounting flange of the machine may or may not extend through the chocks and seat upon leveling plates. The columns and chocks are formed in situ. The structural supports disclosed may be used for new installations or replacement of previous installations after the existing installation has been removed in a suitable manner. After the heavy machinery has been aligned and leveled, the leveling screws and any jack screws are released and the anchor bolts are tensioned to a suitable torque.
In a machine support system, a method of repairing machine supports having a foundation including grouting material with anchor bolts for securing a machine to said support and leveling means to level and align the machine comprising releasing the tension and strain on the machine, removing existing machine support materials for a minimum depth necessary to expose the lowest portion of the machine and providing adequate space for new supports while supporting the machine on temporary supports, forming a layer of grouting material over the foundation, forming multiple columns extending upward from the layer over the concrete foundation under support members of the machine and surrounding, but not adhering to, the anchor bolts, leveling the machine with said leveling means, thereafter forming epoxy chocks upon the columns, surrounding, but not adhering to, the anchor bolts and extending between the columns and said support members for supporting said machine, and thereafter releasing the leveling screws and post-tensioning the anchor bolts to secure the machine upon said machine support.
The method of forming a permanent, non-corrosive level support for a heavy machine which comprises forming a foundation block having anchor bolts secured in and extending upward from said foundation block, forming multiple columns of a grouting material extending upward thereform and surrounding, but not adhering to, the anchor bolts, leveling and aligning the machine by suitable known means, and forming chocks of a grouting material seated on each of said columns and surrounding said anchor bolts, but not adhering thereto, said chocks supporting the heavy machine.
A support for a heavy machine which comprises a foundation block having anchor blots secured in and extending upward therefrom, a seal layer of a relatively impermeable surface upon said foundation block, multiple columns of a grouting material extending upward from the seal layer and surrounding, but not adhering to, the anchor bolts, chocks of a grouting material seated on each of said columns and surrounding said anchor bolts, but not adhering thereto, said chocks supporting the heavy machine from the columns.
