ABSTRACT:
A prefabricated elevator shaft includes a stack of self-supporting prefabricated shaft modules whereby upper shaft modules are supported on lower modules. Each module is of rectangular cross section and vertically spaced portions at each corner define a void between two adjacent modules. The voids are filled with a resin which, after joining together, forms a solid bed supporting the upper module in all directions. On the upper module, screw jacks extend into engagement with the lower module for vertical adjustment. On the lower module, removable guide shafts extend vertically and engage corresponding apertures in the upper module to locate the modules horizontally relative to one another during assembly of a elevator shaft. When the modules are satisfactorily located, the guide shafts can be removed and replaced with bolts to secure the upper module on the lower module.
