Description

Concrete core appearance cutting device

Technical Field

The utility model relates to building engineering detection area, in particular to concrete core appearance cutting device.

Background

The core drilling method is a method for directly estimating the compressive strength of the concrete of the structure by utilizing a core drilling machine and a matched machine tool to drill a core sample on a concrete structural member and directly estimating the compressive strength of the concrete of the structure through the compressive strength of the core sample. The core sample can be used only by processing according to corresponding technical standards, the processed standard core sample is cylindrical, the height-diameter ratio is 1:1, and the two end faces need to be kept flat. At present, when a core sample is processed, a grinding machine is often used for grinding the two end faces of the core sample, so that the height of the core sample and the flatness of the two end faces meet requirements. Because the specifications of the drill bits of the core drilling machine are different, part of the concrete core sample obtained by the core drilling machine is longer, and the conventional grinding machine is used for grinding the concrete core sample to the standard height, so that the time is longer, and a cutting machine is often used for cutting the longer concrete core sample. In the process of cutting the core sample by using the cutting machine, a worker needs to compare the length of the core sample by using a graduated scale or a graduated strip, for example, in an application file with the application number of CN201920266436.3, named as a core sample cutting machine with a clamping mechanism, the graduated strip is marked on a slide rail, by means of the arrangement of the graduated strip, the worker determines the cutting length of the current core sample by using scales on the graduated strip in the process of moving a workbench, the operation mode needs time for length comparison, the efficiency of cutting the core sample is low, errors of the height of the cut core sample caused by artificial reading errors possibly exist, and the height of the core sample is easily caused to be not in accordance with the standard.
