Document Type and Number:
Japanese Patent JP2589456
Kind Code:
B2
Abstract:
PURPOSE: To construct an aerial load bearing lever in desired length by a method wherein an engaging tool is charged, the rear receiving plate of a succeeding unit bearing lever is superposed on the front receiving plate of a preceding unit bearing lever mounted on a bearing member, and the front receiving plate is placed on another bearing member and shifted forward.
CONSTITUTION: Preceding unit bearing levers 4 are placed among adjacent bearing members 2 and first and second engaging holes 9, 12 are conformed, and the suspension levers of engaging tools 14 are charged and the preceding unit bearing levers 4 are installed to the bearing members 2. The rear receiving plates 7 of succeeding unit bearing levers 4 are superposed on the front receiving plates 6 of the preceding unit bearing levers 4, pinholes are engaged into the hinge pins 8 of the preceding unit bearing levers 4 by insertion and the front receiving plates 6 are placed on the bearing members 2. The preceding unit bearing levers 4 are moved in front of the bearing members 2 centering around the hinge pins 8, the engaging holes 9, 12 are conformed and the front ends of the engaging tools 14 are charged, and a process is repeated successively, thus forming an aerial load bearing lever in desired length. The falling of the unit bearing levers 4 is prevented, and through-holes formed to the eyepiece of a side face on the parapet 1 side and a parapet 1 are bound by ropes, etc., during construction work.
