Abstract
Level access structures including a first module and a second module. The first module includes first sidewalls defining a first open shaft with a first top end and a first bottom end opposite the first top end. The second module includes second sidewalls defining a second open shaft with a second top end and a second bottom end opposite the second top end. The second module is complementarily configured with the first level access module. The second module is configured to selectively couple to the first module with the second open shaft aligned with the first open shaft to define a continuous open shaft. The continuous open shaft is configured to contain a level access system.
Claims18
A level access structure, comprising:
- a first module including first sidewalls defining a first open shaft with a first top end and a first bottom end opposite the first top end;
- a second module including second sidewalls defining a second open shaft with a second top end and a second bottom end opposite the second top end;
- and
- a pin system configured to selectively couple the second module to the first module at a building site;
- wherein:
- the second module is complementarily configured with the first module;
- the second module is configured to selectively couple to the first module with the second open shaft aligned with the first open shaft to define a continuous open shaft;
- the first module and the second module are prebuilt remote from the building site as complete, freestanding, modular structures ready to be selectively coupled together at the building site;
- the first sidewalls define a vertical recess proximate the second module;
- the second sidewalls define a second vertical recess proximate the first module and aligned with the first vertical recess when the second module selectively couples to the first module;
- the pin system includes a vertical pin disposed within the first vertical recess and the second vertical recess to couple the first sidewalls to the second sidewalls;
- the continuous open shaft is configured to contain a level access system;
- the first sidewalls define a first sidewall bore extending horizontally through the first vertical recess;
- the second sidewalls further define a second sidewall bore extending horizontally through the second vertical recess;
- the vertical pin defines pin bores extending horizontally through the vertical pin, the pin bores including a first pin bore disposed within the first vertical recess and aligned with the first sidewall bore and a second pin bore disposed within the second vertical recess and aligned with the second sidewall bore;
- and
- the pin system further includes:
- a first horizontal pin configured to selectively extend through the first sidewall bore and the first pin bore to couple the vertical pin to the first sidewall;
- and
- a second horizontal pin configured to selectively extend through the second sidewall bore and the second pin bore to couple the vertical pin to the second sidewall.
