Definitions

  • the present invention relates generally to a jig for assembling dome section panels curved in two dimensions.
  • Dome structures are noted for their strength and stability. They are highly hurricane resistant since they are aerodynamic and earthquake resistant as a result of their ability to distribute and efficiently dissipate the applied stresses.
  • Monolithic dome structures are typically constructed by elaboration of a concrete ring foundation and require that all tools and machinery to be used are brought to the site of construction.
  • a different method of constructing a dome structure involves creating a first circular segment, having a given diameter and height, which is secured to the ground.
  • the circular segment itself is created by connecting a plurality of individual panels which are curved in both their length and height dimension. Circular segments having a successively decreased diameter are subsequently introduced to complete construction of a dome structure. This was disclosed in a previous patent "System and Method for Modular Construction of a Dome Structure and Assembly Components for Facilitating Same.” It necessitates a method for preparing panels curved in two dimensions.
  • an apparatus incorporates an odd number of guide arms that function to guide and secure the positioning of horizontal and vertical components while they are being fastened to form the section panel.
  • each guide arm possesses an arm carriage that houses a lower bracket and an upper bracket for positioning lower and upper plates, respectively, which define the frame of the curved section panel.
  • the apparatus allows vertical components, which impart strength to the curved section, to be positioned between the lower and upper plates, oriented perpendicular to the lower and upper plates and fastened to the lower and upper plates.
  • the brackets can be rotated to accommodate vertical components that are curved in their height (vertical) dimension, which determines the vertical curvature of the section panel.
  • each arm carriage is supported by a base carriage.
  • each base carriage can be moved independently along a curved path, such that the guide arms can be arranged, collectively, in the form an arc. This determines the curvature in the length dimension of the section panel.
  • the location of the base carriages is adjusted according to the desired spacing between vertical components of an assembled curved panel and the desired degree of curvature in the length dimension of an assembled curved panel. Since each guide arm can be moved independently, the guide arms collectively provide a method for introducing curvature either in the form of a circular arc or an elliptical arc. Together, these unique features allow a single apparatus to be employed for the assembly of panels that are curved in two dimensions.

While a preferred embodiment of the present invention is described as having seven guide arms 42, it is within the scope of the present invention that the assembly jig may incorporate any suitable odd number of guide arms 42, specifically, five, seven or nine guide arms.
