Definitions
- the invention refers to a geometrical profile and a flexible assembling method for the module-elements of a geodome.
- a more similar example to the present suggested invention is the "Top-down method of assembling dome structures" belonging to James D McCart, US Patent No. 07228671 , which displays an original method of assembling a modular structure consisting of the carcasses of some modules (the interior part and, possibly, the insulation are to be installed afterwards) using a pulley device.
- the module elements out of which the structure is made have plane joint facets and, consequently, plane predefined dihedral angles from the modules' manufacturing moment (most likely by leaking into moulds).
- the binding system of module elements exemplified in the above invention brings about a number of disadvantages.
- Another disadvantage is rendered by the fact that between the planes of two module-elements, there is a dihedral angle generated by the positioning of the peaks of the module-elements on the surface of the geodome's theoretical sphere. This dihedral angle must be made with sufficient precision so that the sides of two module-elements remain in contact after the assembly of all module-elements.
- This condition would mainly provide self-supporting, meaning that all module-elements would consistently retreive and transmit the mechanical forces given by the structure's weight and by the exterior forces, such as wind pressure, snow weight or frost, as well as it would meet the sealing condition.
- the constructive solution of the analysed invention has the disadvantage that the dihedral angle between two adjacent assembled modules is constructively predefined at a fixed value that does not allow angular positioning of the modules under real manufacturing and assembling conditions of the construction. This is likely to introduce internal tensions in the construction since its installation, which could lead to damaging the assembly profile, breaking the indexing profile, discontinuing the path of transmitting mechanical loads from one element to another element, and thus to overloading other elements and, eventually, to destructing the balance of forces within the structure.
- a purpose of the present invention is to provide an assembly between module-elements which is no longer dependent on the value of the dihedral angle between the planes of two adjacent modules. In this way, it becomes a universal joint for all geodome modules, regardless of decomposition (triangulation).
- Another purpose of the invention is to provide a profile for the joint between two module-elements which would allow the angular auto-positioning of the modules through redistributing and equalizing angular deviations caused by execution imperfections.
- Another purpose of the invention is to provide a profile of the joint between two module-elements which would retrieve and evenly distribute the mechanical forces within the structure and which would ensure, at the same time, the sealing of the joint.
- the semi-cylindrical flexible joint between two module-elements of a geodome consists of the processing, on the entire length of the joint, of a semi-cylindrical convex or, respectively, concave profile so that the convex profile of the side of a module should get assembled with the pair concave profile of the side of the adjacent module.
- the assembling-fastening elements of the sides which come into contact are fastened in an intermediate position so that after installing all the modules they should auto-position themselves on the sphere, as a result of the natural tendency of the minimum effort, retrieving and equally redistributing to all modules the inaccuracies of execution; afterwards, all connections will stiffen in the final tightening stage of the assembling-fastening elements.
- the auto-positioning is possible due to the concave/convex semi-cylindrical contact surface, between two adjacent modules.
- This diaphragm will allow, in the pre-assembling stage, the sliding and auto-positioning of the sides of these modules in contact, after which, at the final fastening, the diaphragm will be crushed between the contact surfaces, taking on their unevenness and roughness, ensuring, on the one hand, the sealing, and on the other hand, an enhanced grip between the sides of the two adjacent modules.
- the semi-cylindrical flexible joint between the module-elements of a geodome has the advantage that it eliminates the difficulty of the strict implementation of the jointing dihedral angle of the elements, as well as the difficulties caused by the imperfections of the surface where the construction will be located.
- Another advantage of the invention is that the semi-cylindrical profile is universally valid for all sizes of module-elements.
- the module-elements that give the best approximation of the theoretically spherical surface of the geodome are the triangles ( Fig. 1, Fig. 2 ).
- the structure can be adapted by changing the number of component modules and module size.
- Triangles assembling is carried out by fastening the adjacent sides ( Fig. 2 ) with some fastening elements 1 . Under these conditions, between the flat surfaces of triangular module-elements the dihedral angle ⁇ appears ( Fig. 3 ).
- the adjacent sides are processed with semi-cylindrical coupling profiles of a concave/convex type, marked "M” ( Fig. 4 ) or "T” ( Fig. 5 ).
- the dihedral angle ⁇ can have the minimum value when the generator A of the convex profile T gets into contact with the generator B from the concave profile M.
- a thin elastic and waterproof diaphragm 2 ( Fig. 6 ). This diaphragm would allow, in the pre-assembling phase, the sliding and auto-positioning of the sides of the modules in contact, and after that, in the final fastening stage, it would be crushed between the contact surfaces taking on their irregularities and roughness, thus providing at first their sealing and then an enhanced grip between the sides of two adjacent modules.
- the semi-cylindrical surfaces can be processed with triangular longitudinal grooves or of other forms, which, at the final fastening of the assembling, will engage/get fixed between them ( Fig. 7 )
