Description

[Detailed Description of the Invention] The present invention relates to a connection structure of a three-dimensional structure.

Connecting bodies each having a female threaded portion are attached to both ends of the rod, and a bolt-like connector is screwed into the connecting bodies to form a joint, and the joints are installed at a predetermined interval. The connector is rotated and screwed into the spheres to connect them, and the rod material of the joining metal is rotated and adjusted while determining whether the screw length of the connector is good or bad. Three-dimensional structures are assembled by adjusting the length, and when assembling a three-dimensional truss in which the rods between the spheres are connected by threaded screws, the length of the metal fittings between the spheres is adjusted by adjusting the length of the metal fittings between the spheres. It was very difficult to adjust and connect according to the combined length, and required skill.

SUMMARY OF THE INVENTION The present invention was devised in order to avoid the drawbacks of the conventional art, and it is an object of the present invention to provide a structure for connecting a three-dimensional structure in which the length of the screw of the metal joint can be easily adjusted.

The present invention will be described below based on embodiments shown in the drawings.

First, referring to FIG. 6, connecting bodies 3, 3 each having a right female threaded portion 2 or a left female threaded portion 2 screwed therein are attached to both ends of the rod 1, respectively.

Connectors 4, 4 each having a right or left large or small diameter screw formed in the shape of a bolt are screwed into the connecting bodies 3, 3 so as to be able to move forward and backward. The joining hardware A is configured as described above.

By the way, the joining hardware A is placed between the spheres B, which are installed at a predetermined interval, and the connectors 4, 4 are rotated and screwed into the space between the balls B, so that the joining hardware A and the sphere are connected. B and B are connected.

Note that the reference numeral 5 in the drawings indicates a rotation stopper. The rotation stopper 5 includes a locking piece 6 that locks on the end of the continuous joint 3 in the shape of a hexagonal bolt head, and a two-pronged locking piece 6 that extends from the locking piece 6 and is clamped around the outer periphery of the connector 4. It is composed of a clamping piece 7. The inner side of the clamping piece 7 is formed into a serrated shape so that the connector 4 and the clamping piece 7 can be firmly clamped together.

When using, screw the large diameter part of the connector into the continuous joint of the joining hardware, leaving the small diameter screw, pull the connector into the continuous joint, and insert the joining hardware between the spheres installed at a predetermined interval. The connector is rotated to insert the small-diameter screw into the spheres, and the spheres are connected with a metal fitting.

Match the distance between the spheres with the tip of the small-diameter screw of the connector that has been retracted into the joint of the joining metal, and insert the small-diameter screw part into the sphere so that the large-diameter screw part moves to the tip of the joint. The sphere and the fitting can be easily connected by screwing them into place. Note that, if necessary, by rotating the joining metal fittings without rotating the connector, the joining metal fittings can be tensioned appropriately.

The present invention is configured as described above, and the connecting portion structure of the three-dimensional structure according to the present invention provides the following effects.

If you adjust the distance between the spheres and the distance between the connector tips of the joining hardware in advance, you can place the joining hardware between the spheres without adjusting the screws later, and then tighten the machine screws on the left and right connectors. Joining hardware can be easily connected by screwing into the sphere.

After the connection is made as described above, it is possible to rotate only the metal fittings and apply appropriate tension to the metal fittings by the action of the tumbler.
