Rollable framework

Abstract

Disclosed is a rollable framework based on the RF (Reciprocal Frame) system, which can be used as post-disaster emergency structures, fair stands, industrial tents, or roof shells to meet the shelter needs of architecture, military, non-governmental organizations, and can be used as a vault by opening the closed rollable form.

1 . A method of obtaining a rollable framework based on an RF system, which takes the form of a vault in its most open state and becomes a roll in its most closed state, the method comprising:
 obtaining a module by connecting non-parallel nexors to parallel nexors with cylindrical joints and parallel nexors to non-parallel nexors with prismatic joints;   combining the mentioned modules by sharing their parallel and non-parallel nexors with neighboring modules, resulting in an arch form;   grouping overhead nexors-in pairs to reduce the degree of freedom of movement of the arch form in the Y plane to one:   wherein the vault form is obtained by lengthening and shortening the lengths of the non-parallel nexors-in the form of an arch with joined nexors so that they do not collide with each other and by adding new modules end-to-end.   
     
     
         2 . A rollable framework based on an RF system, which takes the form of a vault in its most open state and form of a roll in its most closed state, the rollable framework comprising a module with two degrees of freedom of movement, obtained by connecting non-parallel nexors to parallel nexors with cylindrical joints and parallel nexors to non-parallel nexors with prismatic joints. 
     
     
         3 . The method of  claim 1 , wherein the non-parallel nexors, have a square cross-section. 
     
     
         4 . The method of  claim 1 , wherein the parallel nexors have a circular cross-section. 
     
     
         5 . The method of  claim 1 , a rollable framework wherein two of the diagonals of the module have prismatic joints, and the other two have cylindrical joints. 
     
     
         6 . The method of  claim 1 , a rollable framework comprising: combining the modules by sharing their nexors, resulting in a vault form and an arch form containing joined nexors obtained by joining the overhead nexors in groups of two, which enables the control of the curvature. 
     
     
         7 . The method of  claim 1 , wherein the joined nexors and the overhead nexors are made of parallel nexors. 
     
     
         8 . The method of  claim 1 , wherein the lengths of the non-parallel nexors, are changed to obtain the vault form.
