AI Technical Summary

Technical Problem

The template structure of the existing prefabricated box girder molds is fixed, which leads to the cumbersome process of core mold release and is prone to damage the surface integrity of the box girder.

Method used

A disassembly device is designed, including a mounting base and a moving device. The mobile device is detachably connected to the mounting base. The core mold is separated from the surface of the box beam through the mobile device, and the sliding friction is turned into rolling friction by using the moving wheel to achieve rapid pulling and pulling and disengaging of the core mold.

Benefits of technology

The rapid detachment of the core mold is achieved, the demolding efficiency and stability are improved, the damage to the surface of the box beam is avoided, and the integrity of the inner surface of the box beam is ensured.

Abstract

The invention discloses a dismounting device for quick release of a core mold and a using method, the quick dismounting device is arranged at one end of the core mold and used for releasing the core mold from a box girder after demolding, the dismounting device comprises mounting seats and a moving device, the mounting seats are arranged on the core mold at intervals, and the moving device is detachably connected to the mounting seats. The demolding core mold is separated from the surface of the box girder by a certain distance through supporting of the moving device, then sliding friction between the core mold and the box girder is changed into rolling friction through the moving device, rapid pulling and demolding of the core mold are facilitated, efficiency is higher, stability is higher, damage to the surface of the box girder is avoided, and the service life of the box girder is prolonged. The integrity of concrete on the inner surface of the box girder is ensured.
