AI Technical Summary

Technical Problem

The reserved steel bars of prefabricated columns are easily disturbed by steel bar binding and concrete casting during construction of cast-in-place structure floor slabs, resulting in inaccurate positioning and spacing, affecting the success rate of installation of prefabricated columns.

Method used

A prefabricated column reserved steel bar positioning device is designed, including a first positioning device and a second positioning device. The first positioning device consists of a steel bar frame composed of steel bars and a square steel bar positioning hole, and the second positioning device consists of a hollow steel plate and a hollow bolt, which can slide to adapt to the positioning of different prefabricated columns.

Benefits of technology

By setting up two positioning devices, the positioning accuracy of the reserved steel bars of the prefabricated column is effectively controlled, the success rate of the prefabricated column is improved at one time, and the applicability of the device is improved, with a good economic effect.

Abstract

The utility model discloses a prefabricated column reserved steel bar positioning device, which is arranged on the reserved steel bar at the upper end of the prefabricated column structure, and includes a first positioning device and a second positioning device. The first positioning device is arranged below the second positioning device. The first positioning device includes a steel bar frame composed of steel bars, and the edges of the steel bar frame form steel bar positioning holes. The second positioning device includes a hollow steel plate and a hollow bolt. Sliding grooves are evenly opened on the hollow steel plate. Some hollow bolts are vertically penetrated in the sliding grooves, and the remaining hollow bolts directly pass through the hollow steel plate vertically. The lower end of the hollow bolt is limited by a nut. The positions of the steel bar positioning hole and the hollow bolt correspond to the positions of the reserved steel bars respectively. The reserved steel bars pass through the steel bar positioning hole and the hollow bolt in sequence to achieve positioning. The utility model is provided with two positioning devices for positioning, which effectively controls the positioning accuracy of the reserved steel bars of the prefabricated column, and greatly improves the success rate of the one-time installation of the prefabricated column.
