Module elevator system for installation in a multi-story building

A modular elevator system for installation in a multi-story building by means of suitable lifting apparatus, comprising;

• a. a series of identical elevator modules each of which
• 1. is of precast concrete construction that includes internally embedded reinforcing rods,
• 2. includes front, back, and opposed side walls and upper and lower surfaces that form a vertical elevator shaft of at least one-story height,
• 3. has at least one door opening provided in the front wall portion thereof,
• 4. has a plurality of metal support channels embedded within and forming a part of the inside wall surfaces of said modules for rail and door supporting purposes,
• 5. has upper and lower vertically aligned leveling and attachment means provided on each top and bottom surface of at least two of said opposed walls;
• the leveling means on said top surface including first metal angle members embedded therein;
• the leveling means on said bottom surfaces including recesses having second metal angle members secured therein and;
• third metal angle members for interconnecting said first and second angle members following leveling and alignment of said modules by the lifting apparatus;
• 6. has means for rigidly securing said adjusted, vertically adjacent modules to each other and to adjacent floor surfaces of each floor of said building, whereby an elevator shaft consisting of vertically adjacent modules is integrally secured to said building throughout its height.
