Modular elevator shaft assembly and method for making the same
An elevator shaft assembly and a method for forming the same includes a plurality of modules, each of the modules having a plurality of walls with an upper perimeter edge and a lower perimeter edge and spaced apart elevator rails. Adjacent modules are aligned with each other along mating upper and lower perimeter portions with complementary aligning members that are joined together with a fastener, the modules when joined together forming a tubular structure.
1. An elevator shaft assembly comprising:
a plurality of modules, each of the modules including:
a plurality of walls with an upper perimeter edge and a lower perimeter edge;
spaced apart elevator rails; and
wherein adjacent modules are aligned with each other along mating upper and lower perimeter portions with complementary aligning members that are joined together with a fastener, the modules when joined together forming a tubular structure; and
wherein the complementary aligning members comprise a projection provided on a first one of the plurality of modules and a receiver provided on a second one of the plurality of modules, the fastener comprising an element inserted into each pair of the complementary aligning members fastening the projection to the receiver, and a flange engaging a lower surface of the receiver to inhibit separation of the projection from the receiver when the fastener is received in the complementary aligning members.
2. The elevator shaft assembly of claim 1 wherein the element comprises a bolt.
3. The elevator shaft assembly of claim 2 wherein the bolt extends through a bore in the receiver and engages a threaded aperture in the projection.
4. The elevator shaft assembly of claim 1 wherein the element comprises a pin.
5. The elevator shaft assembly of claim 4 wherein the pin fastens the projection to the receiver with location of the pin in one or more apertures.
6. The elevator shaft assembly of claim 4 wherein the pin fastens projection to the receiver.
7. The elevator shaft assembly of claim 1 wherein the aligning members are secured with complementary engaging surfaces.
8. The elevator shaft assembly of claim 7 wherein the complementary aligning members include tapered surfaces that align the aligning members with respect to each other.
9. The elevator shaft assembly of claim 8 wherein the receiver is provided on the upper perimeter portion of the first one of the plurality of modules and the projection is provided on the lower perimeter portion of the second one of the plurality of modules, the second one of the plurality of modules being stacked upon the first one of the plurality of modules.
10. The elevator shaft assembly of claim 1 wherein the fastener comprises a weld formed between the complementary aligning members.
11. The elevator shaft assembly of claim 3 , wherein the flange engages a lower surface of the receiver to inhibit separation of the projection from the receiver when the bolt is received in the threaded aperture.
12. A method of forming an elevator shaft assembly from a plurality of modules, each of the modules including a plurality of walls with an upper perimeter edge and a lower perimeter edge and spaced apart elevator rails, the method comprising:
stacking two of the plurality of modules upon each other, where each module includes an elevator rail, the elevator rails being aligned with each other; and
joining two of the plurality of modules together along opposed upper and lower perimeter portions with a plurality of fasteners, each fastener joining complementary aligning members provided on the opposed upper and lower perimeter portions of the modules, wherein the complementary aligning members comprise a projection provided on a first one of the plurality of modules and a receiver provided on a second one of the plurality of modules, each fastener further comprising a flange engaging a lower surface of the receiver to inhibit separation of the projection from the receiver when the fastener is received in the complementary aligning members.
13. The method claim 12 and further comprising inserting the fastener between each pair of the complementary aligning members.
14. The method of claim 12 wherein the complementary aligning members comprise a projection provided on a first one of the plurality of modules and a receiver provided on a second one of the plurality of modules, the fastener fastening the projection to the receiver.
15. The method of claim 14 wherein the receiver is provided on the upper perimeter portion of the first one of the plurality of modules and the projection is providing on the lower perimeter portion of the second one of the plurality of modules, the second one of the plurality of modules being stacked upon the first one of the plurality of modules.
16. The method of claim 12 wherein the complementary aligning members include tapered surfaces that align the aligning members with respect to each other.
17. The method of claim 12 wherein the fastener comprises a weld.
