US 4,986,040 A · Modular elevator shaft

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.

Dependent claims

An elevator shaft comprising:

a generally vertically extending stack of individual, self-supporting, prefabricated shaft modules, each said module having a structural strength sufficient to support the module or modules above thereby permitting supporting of the shaft from a lower one of said modules;
and
means provided on at least one of adjacent ones of said modules for defining a void between vertically spaced portions of said adjacent modules to contain a fluid material, the void being filled with a structural resin which sets to form a solid bed of resin material supporting and maintaining said vertically spaced portions of said adjacent modules apart.
