AI Technical Summary

Technical Problem

In existing technologies, the chamfering of cylindrical concrete foundations relies on manual operation, which leads to unstable chamfering quality and difficulty in controlling the angle and aesthetics.

Method used

Design a compass-type concrete foundation chamfering device, including a cylindrical mold, an intermediate rod, a support bracket assembly, and a chamfering scraper. Utilize the compass principle to achieve automated chamfering. The support bracket assembly is fixed to the cylindrical mold, and the intermediate rod drives the chamfering scraper to rotate and form an arc-shaped chamfer.

Benefits of technology

It improves the continuity and flatness of chamfering, reduces reliance on operator skill, ensures chamfering quality and aesthetics, and the device is detachable and reusable.

Abstract

This invention discloses a compass-type concrete foundation chamfering device, comprising a cylindrical mold, an intermediate rod, an intermediate shaft, a support bracket assembly, a chamfering bracket assembly, and a chamfering scraper for chamfering the circular edge of a circular concrete foundation. The support bracket assembly is mounted on the outer wall of the intermediate shaft and is installed on the cylindrical mold. The intermediate rod movably passes through the intermediate shaft, and the chamfering bracket assembly is fixedly mounted at its lower end. The chamfering scraper is mounted on the free end of the chamfering bracket assembly. This device utilizes the compass principle, has a simple structure, is easy to operate, produces high-quality chamfers, offers good operational continuity, and can be disassembled and stored for easy reuse.
