Abstract

The invention provides a rapid mounting auxiliary device and a mounting method of a prestressing jack. The device comprises an annular base formed by abutting two semicircular brackets, positioning connecting plates vertically connected to the sidewalls of the semicircular brackets, and a group of horizontal steel needles orderly and horizontally penetrating through the two semicircular brackets. The jack mounting auxiliary device is especially suitable for the mounting of the jack in a vertical use state, and capable of quickly mounting the jack in place, and meanwhile, capable of guaranteeing that a plurality number of steel strands and steel beams are not crossed and twisted with each other, and therefore, the mounting accuracy and the working efficiency are improved, and the construction quality is guaranteed. The device is reasonable in structural design, light in weight and flexible in use; the mounting method is simple and easy to operate, and the mounting time is saved and the mounting efficiency is improved; after mounting, the jack in obvious in effect, and safe and reliable; the crossing and twisting conditions of the steel strands and the steel beams are effectively avoided, the mounting accuracy is improved, the construction quality is guaranteed, and the problem of difficult mounting in the vertical use state of the jack is solved.

Description

technical field [0001] The invention relates to a jack installation auxiliary device and an installation method thereof. Background technique [0002] In the post-tensioning and prestressing construction process of nuclear power plants, it is an essential and important process to use jacks to tension steel beams. In the jack tensioning process, there are more than 50 working steel beams arranged in a fixed form. During installation, all steel beams need to penetrate from the top of the jack to the tail; the jack can be in various states such as horizontal, upright and reverse, and inclined when working, and the installation of the vertical working state of the jack is the most difficult. The same number of guide bushings as the steel beams will protrude freely, which makes it impossible to penetrate the steel beams one by one row by row. It is impossible to ensure the one-to-one correspondence between the steel beams and the guide sleeves, which will easily cause the steel b...
