AI Technical Summary

Technical Problem

Existing gypsum board fire resistance testing devices are inefficient in sample replacement and feeding processes, and can only be tested at a fixed angle, resulting in long testing cycles and insufficient data reliability.

Method used

A gypsum board fire resistance testing device was designed. The sample replacement and feeding process are separated into different positions and support both horizontal and vertical testing modes. The sample angle is adjusted by using a stepper motor to drive the rotating disk and the threaded hole. It is equipped with two independent combustion components to simulate different stress conditions.

Benefits of technology

It improves operational safety and efficiency, ensures the accuracy and comprehensiveness of test results, provides more comprehensive data support, and adapts to the stress conditions of gypsum board in different building environments.

Abstract

The utility model relates to the technical field of gypsum board detection, and discloses a gypsum board fire resistance detection device which comprises a bottom plate, a heat insulation frame fixedly installed on the bottom plate, a shielding assembly arranged on the heat insulation frame, a fixing frame fixedly installed on the bottom plate, a stepping motor arranged on the fixing frame, and a rotating shaft fixedly installed at the output end of the stepping motor. A rotating disc is fixedly mounted on the rotating shaft, connecting rods are fixedly mounted on the rotating disc at equal intervals, mounting blocks are fixedly mounted on the connecting rods, placing assemblies are arranged on the mounting blocks, and a combustion assembly is arranged in the heat insulation frame. According to the utility model, the feeding and discharging activities of the gypsum board sample are not carried out at the same position, so that the operation safety and the working efficiency are improved, and meanwhile, the rapid switching of a horizontal test mode and a vertical test mode of the to-be-tested gypsum board can be realized, thereby providing comprehensive data support for the fire resistance of the gypsum board; and the experimental diversity and the result reliability are enhanced.
