AI Technical Summary

Technical Problem

When testing the pressure strength of steel using a hydraulic pressure testing machine, the oxide layer or irregular layer on the surface of the steel may cause local cracking, resulting in the splashing of steel slag or steel chips. Furthermore, excessive pressure may lead to brittle fracture, posing a safety hazard.

Method used

A steel strength testing device for building inspection was designed, including a hydraulic pressure testing machine, a hydraulic cylinder, a pressure sensor, a clamp, and an adjustment and protective device. The protective cover is adjusted to completely cover the area around the testing position to prevent steel slag from splashing.

Benefits of technology

It effectively prevents steel slag splashing, reduces safety hazards during the use of hydraulic pressure testing machines, and improves testing safety.

Abstract

This utility model provides a steel strength testing device for building inspection, relating to the field of strength testing devices. The utility model includes a hydraulic pressure testing machine. After the steel is placed and fixed on a clamp, the threaded rod is manually pulled upwards through a sliding hole to a certain position. Then, the adjusting protective cover slides upwards within the inner wall of the grooved protective cover to a certain position, completely covering the clamp and the steel. At this point, the screw hole block is screwed onto the threaded rod to a certain position until one side abuts against one side of the grooved protective cover, thus fixing the adjusted protective cover in place. This allows the adjusting protective cover and the grooved protective cover to completely protect the area requiring pressure strength testing. During the testing process, if steel slag splashes, the adjusting protective cover and the grooved protective cover can block the slag, preventing harm and reducing safety hazards during the use of the hydraulic pressure testing machine.
