Abstract
Description
〔1〕まくら木用ねじくぎの構造において、外周面に二条ねじが形成され、まくら木に対する締付と緩め作業の短縮化を図るようにしたことを特徴とする。
1.使用ボルト
従来品:レール用ねじくぎ 22mm×140mm Bタイプ 4本
本発明品:レール用ねじくぎ 二条ねじSS 4本
2.使用まくら木
(A)S社製:合成まくら木 1個
(B)A社製:合成まくら木 1個
3.試験結果
締付はインパクトレンチでの締付
トルク測定はトルクレンチを使用
ねじくぎねじ込み長さは80〔mm〕
1本のまくら木に4本のねじくぎをねじ込み試験した結果
トルク値の面から見ると、BタイプはAとBで大きな違いがあるが、二条ねじはどちらもほぼ同等のトルク値で締付と緩めを行うことができた。
2 まくら木用ねじくぎの頭部
3 まくら木用ねじくぎの鍔部
4 まくら木用ねじくぎの二条ねじ部
