DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings, but the present invention is not limited thereto.

The dome connector 10 according to the present invention comprises a connector hub 12, a connector joint 14, a fastening bolt 16 and a fastening nut 17 as shown in Figs.

The connector hub 12 includes a hexagonal cylindrical upper cylindrical body 121, a lower cylindrical body 122 having a hexagonal cylindrical shape and arranged on the same straight line at a predetermined distance from the upper cylindrical body 121, an upper cylindrical body 121, A hub bridge 123 connecting the lower cylindrical body 121 and a hexagonal upper plate 124 and a lower plate 125 joined to the upper end of the upper cylindrical body 121 and the lower end of the lower cylindrical body 122 .

The upper plate 124 and the lower plate 125 have the same size and are formed with through holes 124a and 125a through which the fastening bolts 16 are inserted on the same straight line. The hub bridge 123 has a radial structure extending radially toward the hexagonal vertex at the center of the upper cylindrical body 121 or the lower cylindrical body 122.

The connector joint 14 is positioned on the outer surface side of the connector hub 12 and is connected to the connector rod 210 of the dome structure 200 in FIGS. The connector joint 14 includes a joint plate 141 having an inner curved surface having the same radius of curvature as that of the upper cylindrical body 121 or the lower cylindrical body 122 and a joint plate 141 provided on the rear surface of the joint plate 141, And a joint arm 143 provided on the front surface of the joint plate 141. The engaging boss 142 has an engaging hole 142a in which the engaging hole 142a is inserted, The end of the joint arm 143 has a hemispherical groove 144 for connecting a connector rod having a constant radius of curvature r and a plurality of hemispherical groove slits 145 cut around the hemispherical groove 144 for connector rod connection .

The connector rod 210 connected to the joint arm 143 is in the form of a ball whose end has the same radius of curvature corresponding to the hemispherical groove 144. Therefore, the ball shape of the connector rod 210 is forcefully spherically coupled to the hemispherical groove 144 to form a ball joint. Upon forced coupling, the hemispherical groove slit 145 helps the hemispherical groove 144 to expand as the gap widens.

Therefore, the connector rod 210 is ball jointed to the connector arm 182, and can be rotated by a predetermined angle around 360 degrees, so that the connector rod 210 can be easily installed in a hexagonally arranged structure in the dome structure 200 of FIG.

The fastening bolt 16 is used to connect the connector joint 14 to the connector hub 12 and is fixed to the upper plate 124 and the lower plate 125 and is connected to the connector joint 14, ). Therefore, the fastening bolt 16 is longer than the distance between the upper plate 124 and the lower plate 125. In this embodiment, the fastening bolt 16 is not provided with a bolt head and is provided with two fastening nuts 17 with screws at both ends thereof, but may be provided with one fastening nut 17 when the bolt head is provided.

In the dome connector 10 constructed as described above, six connector joints 14 are assembled by screwing the fastening bolts 16 and the fastening nuts 17 to the connector hub 12.

At this time, the connector joint 16 is brought into close contact with the outer surface of the upper cylindrical body 121 and the lower cylindrical body 122, and the fastening bolt 16 is fastened to the fastening holes 121a of the upper cylindrical body 121 and the lower cylindrical body 122 122a and the engaging boss 142, and then is fastened with a fastening nut 17, as shown in Fig. Thus, the joint arm 143 of the connector joint 16 is disposed radially with respect to the center of the connector hub 12.

At this time, the hub bridge 123 divides the connector hub 12 into six equal parts, thereby establishing a uniform spacing of the connector joints 16.

The completed dome connector 10 thus assembled is assembled as necessary and applied to the construction of the dome structure 200 as shown in Figs. That is, in the dome structure 200, the dome connector 10 is installed to connect the ends of the connector rod 210 to form a dome frame.

The dome connector 10 constructed and assembled as described above can be assembled only by ball jointing the connector rod 210 with the hemispherical groove 144 for connecting the connector rod of the connector joint 14, thereby simplifying the construction. The hub bridge 123 can also be used to form a rigid connector.
