AI Technical Summary

Technical Problem

Existing tensioning platforms have limited functionality, occupy a large area, cannot meet the tensioning requirements of various precast components, and are inconvenient to install and dismantle.

Method used

The prestressing tendons are tensioned using a socket-type tensioning platform, which includes a platform, columns, and a tensioning drive device. The columns are plugged into the sleeves and have an inclined section in the middle. The columns are detachable through the combination of the sleeves and columns. The columns can be set according to the required position and number. The prestressing tendons are tensioned by the connectors and the tensioning drive device.

Benefits of technology

It improves the applicability and economy of tensioning platforms, reduces the floor space required, facilitates installation and disassembly, is suitable for the production of various precast components, and saves costs.

Abstract

This invention relates to the field of precast component technology, and more particularly to a socket-type tensioning platform and tensioning method. The tensioning platform includes a platform, a column, and a tensioning drive device. Multiple sleeves are arranged in an array along the width direction of the platform, and the column is inserted into the sleeves. An inclined section is provided in the middle of the column, which is located between a first section of the column on the platform and a second section of the column located inside the sleeve. The side of the first section of the column and the side of the second section of the column opposite to the first section abut against the inner sidewalls of the sleeves, respectively. The fixed end of the tensioning drive device is fixedly connected to the column, and the telescopic end of the tensioning drive device is fixedly connected to the prestressing tendon of the precast component to tension the prestressing tendon.
