Abstract
A prefabricated elevator shaft module is foldable for volume reduction for transport and storage. The side walls of the module each include hinge points defining two vertical axes, one axis being inwardly foldable and the other axis being outwardly foldable. When the walls are folded together, apertures in a lower angle frame and a hinge lug are aligned for the insertion of a bolt for the mechanical fixation in the folded together position.
Claims13
A prefabricated elevator shaft module for the construction of complete elevator shafts in building structures comprising:
- a plurality of generally vertically extending walls connected together to form a multi-sided module including a pair of spaced apart side walls connected together by a front wall and a rear wall spaced apart a first predetermined distance, each of said spaced apart side walls being foldable along at least one generally vertically extending axis whereby, when said spaced apart side walls are folded, said spaced apart front and rear walls are spaced from each other by a second predetermined distance less than said first predetermined distance.
A prefabricated elevator shaft module for the construction of complete elevator shafts in building structures comprising:
- a plurality of generally vertically extending walls including a pair of side walls connected to each other by front and rear walls spaced apart a first predetermined distance, each of said side walls being foldable along two generally vertically extending axes, one of said axes being foldable inwardly and the other axis being foldable outwardly, whereby when said side walls are folded, said front and rear walls are spaced from each other by a second predetermined distance less than said first predetermined distance.
A prefabricated elevator shaft module for the construction of complete elevator shafts in building structures comprising:
- a plurality of generally vertically extending walls including a pair of said walls connected to each other by front and rear walls spaced apart a first predetermined distance, each of said side walls being foldable along two generally vertically extending axes to space said front and rear walls from each other by a second predetermined distance less than said first predetermined distance, each of said walls being formed from a plurality of identical individual elements, and including upper and lower angle frames attached to upper and lower edges respectively of said walls.
