Adjustable Modules for Variable Depth Structures

摘要

This disclosure presents a new strategy for modular construction: an adjustable module. This disclosure develops a new adjustable module comprised of a four-bar linkage which can form more efficient variable depth structures. Applications can include rapidly erectable bridges, roofs, buildings, and grid shells, among others. This disclosure provides specific detail related to rapidly erectable bridge applications for variable depth arch forms. Existing rapidly erectable, steel panelized bridge systems have limited material efficiency as they are comprised of rigid modules in a girder-type configuration. This disclosure shows that the module can form variable depth three- and two-hinged arches which increase the material efficiency. The module and other arch components can be made of standard rolled steel sections, thereby forming a versatile, kit-of-parts systems.

主权项

1. An adjustable module for forming a variable depth structure comprising:
a first link with a first end and a second end; a second link with a first end and a second end operably connected to the first end of the first link with an upper revolute joint; a third link with a first end and a second end operably connected to the first end of the second link with a first lateral revolute joint; and a fourth link with a first end and a second end operably connected to the first end of the third link with a lower revolute joint and operably connected to the first link at a second lateral revolute joint; wherein the adjustable module is configured to form a variable depth structure by preventing the relative rotation of the first link, the second link, the third link, and the fourth link.
