AI Technical Summary

Technical Problem

Existing prestressed slab production molds are prone to severe impacts when they suddenly break, leading to mold structure deformation and damage to precision components, thus affecting equipment lifespan.

Method used

A mold for a prestressed slab production line in a subway station was designed, comprising a tensioning component and a control component. The tensioning component is equipped with a buffer component to absorb impact energy, and the control component triggers sliding friction under excessive tension to limit the maximum transmitted force and avoid equipment damage.

Benefits of technology

This effectively avoids damage to molds and equipment in the event of sudden breakage, ensuring the dimensional accuracy of subway station components and the long service life of equipment.

Abstract

The application discloses a prestressed middle plate production line mold for a subway station, which comprises a fixed bottom plate, a prestressed middle plate mold fixedly connected to the upper surface of the fixed bottom plate and used for pouring concrete, a tensioning assembly and a control assembly. In order to solve the problem that common steel bar tensioning equipment may be broken due to stress mutation or material defects when stress is applied, and the mold or equipment is easily damaged by instant energy release, the tensioning assembly is designed, the inside of the tensioning assembly is provided with a buffer assembly, the buffer assembly can play a buffering role when stress is applied, can absorb impact energy when overload occurs, and the control assembly is further designed, sliding friction is triggered under over-limit tension through the control assembly, the maximum transmission force is limited, and equipment damage caused by sudden breakage is avoided.
