Embodiment Construction
[0035] The invention aims at the problems existing in the current hoisting system, and solves the defects that it needs to be repeatedly disassembled and assembled during use, the construction is cumbersome, the efficiency is low, and the large-length steel bars cannot be hoisted in batches and quickly. The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0036] Such as Figure 1-7 As shown, the present invention provides a batch hoisting device for the main bars of a towering concrete structure, which includes a main frame 1 , a hanger 4 and a steel bar positioning frame 5 . The middle part of the main frame 1 is provided with a hanging platform 2 . The present invention drives the main frame 1 and the hanging platform 2 to hoist the steel bar group through the spreader 4, and places the steel bar group at a designated position through the steel bar positioning frame 5, so that the efficient and fas...

The invention discloses an apparatus and a method for batch hoisting main reinforcement of a high concrete structure. The apparatus for batch hoisting the main reinforcement of the high concrete structure comprises a main framework, a hoisting appliance and a reinforcing steel bar positioning frame, wherein the middle part of the main framework is provided with two hanging table board, the inner side edges of the two hanging table boards are opposite to each other, the hanging table board is provided with a hanging table ear plate, the hanging table ear plate is hinged with the main framework,the hoisting appliance comprises hoisting arms, two groups of the hoisting arms are provided and respectively used for driving the two hanging table boards to rotate, so that the inner side edges ofthe two hanging table boards approach each other or leave each other, the reinforcing steel bar positioning frame is positioned on a to-be-installed position of a reinforcing steel bar and comprises alimiting plate, the front side and the rear side of the limiting plate are respectively provided with a positioning plate and a positioning frame, and a positioning groove is formed between the positioning plates. The reinforcing steel bar group can be clamped and released by virtue of the weight of the main framework and the hanging table plate, so that the problems of difficulty in positioningand low efficacy in the reinforcing steel bar hoisting process can be solved, the hoisting method is simple, the use is flexible and effective, and the apparatus has the advantage of energy conservation and consumption reduction.
Description
technical field [0001] The invention relates to the field of bridge construction, in particular to a batch hoisting device and method for the main bars of a towering concrete structure. Background technique [0002] With the vigorous development of bridge construction, the spanning capacity of bridges is getting bigger and bigger, and the bearing capacity is getting bigger and bigger. High-rise concrete structures such as bridge towers are more and more widely used in bridge engineering; and the main reinforcement of high-altitude concrete construction generally adopts large-diameter straight thread sleeves. With the increase of construction height and the maturity of high-altitude climbing formwork construction technology and on-site control technology, large-diameter steel bars with lengths of 6m and 9m are becoming more and more common. [0003] The installation methods of large-diameter and super-long steel bars mainly include: first, use hoisting equipment to hoist them...
