The present invention relates to a hub connector for a geodesic dome-shaped house. More specifically, a frame holder (1) is composed of a joint bracket (101) with a combining hole (102) in a longitudinal direction; a supporting wall (103c) attached on the external vertical wall (101c) of the joint bracket; a pair of side walls (103) formed on the external side of the supporting wall; a combining groove (104) formed between both the side walls (103); a frame bar (2) inserted into the combining groove; and a through hole (103a) formed on the side walls (103); and is fixed by a fixing unit which passes through the through hole. At least four to six frame holders are arranged in a radial manner. Joint brackets (101) of all frame holders (1) are successively overlapped and a fastening bolt (3) passes through the combining holes (102) formed on all joint brackets (101) are is fastened with a fastening nut (4) such that the heights of sidewalls (103) separately formed on all joint brackets (101) are the same regardless of overlapped joint brackets. Thus, a plurality of frame holders constituting a hub connector freely rotates based on the fastening bolt as a central axis. Therefore, the distortion of the frame bars fixed on the frame holders of the hub connector is prevented in the process of constructing of a geodesic dome-house, and thus precise and firm construction is possible for the geodesic dome-house. |
