Quick binding device for special-shaped high pier reinforcement cage

Abstract

The invention relates to a quick binding device for a high pier reinforcement cage, and the device is provided with a horizontal binding jig frame and a ceiling; and positioning devices with differentheights and different shapes are arranged on the horizontal jig frame to adjust the special-shaped requirement of an external structure of a pier body reinforcement. The horizontal binding jig frameis provided with an inner side jig frame and an outer side jig frame which can slide so as to achieve smooth mounting and dismounting of the steel reinforcement framework. The device has the advantages that high pier reinforcing steel bars are bound on the horizontal jig frame, the construction precision and quality control of reinforcing steel bar binding can be improved, and the safety risk in the construction process is reduced. Through the arrangement of the ceiling device, the reinforcing steel bars and personnel are effectively protected from being exposed to the sun and rain, and humanistic care to industrial workers is also improved on the premise that the reinforcing steel bars are protected against corrosion.

Description

technical field [0001] The invention relates to a construction method for quickly binding steel bar skeletons of special-shaped high piers, and belongs to the technical field of bridge construction. Background technique [0002] In recent years, my country's infrastructure investment has been continuously increasing, and the bridge industry has developed rapidly. At the same time, the scale of the project and the difficulty of construction have also increased, especially the height of the pier body and the span of the beam body. The construction is extremely difficult, the risk is extremely high, and the cost is difficult to control. In order to further control the construction cost and reduce the safety risk, the binding of the steel skeleton of the tall pier has become an important part that affects the safety and quality of the project. [0003] In the existing bridge construction, the traditional on-site vertical binding method at the pier site is generally used for the c...

AI Technical Summary

Problems solved by technology

Due to the high pier body, an additional rigid framework needs to be installed on the inside of the steel skeleton during on-site binding to improve its vertical stiffness and positioning accuracy of the steel bars during the binding process. This construction method has long construction periods and risks of high-altitude operations. It is difficult to meet the requirements of modern rapid construction due to the problems of large size, low construction efficiency and high investment in rigid framework.
