Track-type heightening frame device for heightening construction of pier body steel bars and heightening method of track-type heightening device

Abstract

The invention discloses a track-type heightening frame device for heightening construction of pier body steel bars and a heightening method of the track-type heightening frame device. The problems that in the prior art, high-pier steel bars cannot move directionally in space, during heightening construction, lengthening is difficult, workers are fatigable, the efficiency is low, and safety is loware solved. The track-type heightening frame device comprises a base, supporting frames, an I-shaped traveling track, electric hoists, connectors, steel bar parts and sleeves. The heightening method mainly comprises the steps that the track-type heightening frame device is designed and manufactured firstly and then mounted, then the steel bars are moved in the vertical direction and then moved inthe horizontal direction, then the to-be-heightened steel bars are mounted in a heightening mode, and after all the steel bars at the same working section of a pier body are heightened according to the method, the track-type heightening frame device is hoisted to the ground for standby application. The track-type heightening frame device can well complete heightening work of the pier body steel bars, is less affected by the construction environment condition, and is convenient to machine, low in consumable quantity, easy to operate, high in heightening construction efficiency and high in construction safety.

Description

technical field [0001] The invention relates to a track-type elevated device and a height-connecting method used for the height-connecting construction of pier body steel bars, in particular to a construction method suitable for directional, fast transfer and lengthening of high-pier steel bars. Background technique [0002] The heightening construction of steel bars mostly adopts the form of manual handling and installation. The construction process is as follows: first, the main reinforcement is transported to the construction platform by a tower crane, and then the workers use the rigid frame inside the pier body as a platform to install it. One person delivers it on the climbing frame platform, and the remaining 3 people work between platforms on different layers of the rigid frame. Connect and place the main reinforcement, and finally the bottom of the main reinforcement is connected with a sleeve, and the hanging part of the main reinforcement is tied to the positionin...
