    Abstract: A joint device enables to join a brace member, into which regulated pretension is exactly introduced, to unmovable connector nodes, comprising a steel rod 1 having a swelled portion 1A and a threaded connector portion 1B formed on the end thereof, respectively, one sleeve 3 providing an external threaded part 3A joined to one node 2M, which contacts a swelled portion 1A: and another sleeve 4 providing an external threaded part 4A joined to node 2N, which engages threaded connector portion 1B. The length from a node-contact face 3c of sleeve 3 to a node-contact face 4c of sleeve 4 is selected equal to difference of length between both nodes 2, 2 from length for generating a preferable elongation enough to introduce regulated pretension into steel rod 1. A brace member 13 is disposable between both nodes 2, 2 and regulated pretension is introducible thereinto when depth of connecting screw hole 2m of sleeve 2M is equal to or more than difference of summation of length of joining threaded part 3A, length of-swelled portion 1A and length of joining threaded part 4A from length for generating an elongation.
