Coupling connector and geodome frame made therewith

Abstract

An invention relates to the field of construction and may be used to design a frame of a geodesic dome (a geodome), in particular, for connecting geodome rods in spatial structures of frames of build-up and modular building structures having a spherical or dome-shaped form to serve various purposes. A coupling connector for a geodesic dome frame comprising a body having holes radial to the vertical axis of the body and positioned at an angle to its horizontal plane, wherein the body comprises at least six radial holes positioned to each other at the angle of 60 degrees, the axis of radial holes being at an angle within 6 to 10 degrees to the horizontal plane of the body, radial holes having, at least partially, a conic part with a cone angle within 4 to 10 degrees to the axis of holes, with hole diameter to length ratio of at least 0.5, and the body is further equipped with through holes, each coupled with one radial hole, at one side, and a body surface, at the other side, so the axisof through holes is positioned in one plane with the axis of a radial hole to which a through hole is coupled. A geodesic dome frame formed with the coupling connector comprises coupling connectors with holes, in which rod ends are positioned to form multiple interconnected triangles forming the surface of the geodesic dome. The frame comprises the geodesic dome and the coupling connector havingfive radial holes, in which rods are positioned at an angle ranging between 6 and 10 degrees to the horizontal plane of the body and at an angle of 72 degrees to each other, each coupling connector comprises fixators positioned in axial through holes so that each fixator is coupled with a rod end positioned in each radial hole of the said coupling connectors.

Description

technical field [0001] The invention relates to the field of construction and can be used for the construction of frames for geodesic domes (faceted domes), in particular prefabricated and collapsible in spherical or dome-shaped form for connecting the bars of the faceted domes to various purposes In the spatial structure of architectural structural frames, such as cinemas, planetariums or large event buildings (exhibitions, concerts, seminars, etc.), as well as temporary and mobile structures. In this specification, the frequency of division in a multifaceted dome (geosphere) frame refers to the number of different structural elements (brackets) used to build the frame. Typically, this number is represented by the letter V and the numbers 2 through 8 (V4, V8, etc.). It is well known that the greater the number of supports used, the greater the strength and reliability of the faceted dome. [0002] Also in this specification, a multifaceted dome (geosphere) refers to an appr...

Problems solved by technology

However, due to the presence of the threaded connection, the fixing structure of the tubular element is relatively unreliable, and also by the structure of the tubular element, which is cantilevered between the washers and where it is connected to the washers can be damaged under various loads

Also, the faceted dome structure formed in this way is relatively difficult to assemble when assembled due to the need to pre-arrange the tubular elements at an angle, which requires site-specific placement of the faceted dome, which increases the time it takes to form

Furthermore, removal of such a frame requires an additional operation to break the gasket and release the tubular element from the detachable design of the connector, which somewhat limits its use to certain types of mobile and temporary building structures
