支柱と腕木の接合構造

Connecting structure of support and bracket

Abstract

(57)【要約】 【課題】 支柱に対する腕木の接合において、専用の装 置(溶接装置、加締め装置等)や工具を使用することな く、ワンタッチで定着することができる接合構造を提供 する。 【解決手段】 支柱の長手方向周面に沿って、腕木を接 合固定する構造であって、支柱3の長手方向に沿ってそ の周面に係合溝6を形成し、他方、前記支柱に接合する 腕木4は、板厚を係合溝の開口幅に相当する厚さとし、 且つ前記支柱の係合溝における開口と対向する奥側の壁 に該腕木の接合側端面を突き当てた時、係合溝の開口縁 内面に当接する係合凸部10を該腕木の側面に突設し た。
PROBLEM TO BE SOLVED: To provide the connecting structure capable of fixing in a single operation without using a dedicated device (welding device, caulking device, or the like) and a dedicated tool when connecting a bracket to a support. SOLUTION: This is the structure for connecting a bracket to a support for fixation along the longitudinal peripheral surface, an engagement groove 6 is formed in the peripheral surface of a support 3 along the longitudinal direction thereof. A bracket 4 has a plate thickness corresponding to the opening width of the engagement groove, and an engaging projection part 10 for abutting on the inner surface of the opening edge of the engagement groove when the connecting side end surface of the bracket abuts on a wall of a depth part opposite to the opening of the engagement groove of the support is provided so as to be projected from a side surface of the bracket.
