Description

Technical Field

[0001] The utility model relates to the technical field of building material detection, in particular to a building material hardness detection device. Background Art

[0002] With the progress of science and technology, the standards of national supervision are becoming more and more stringent. At present, the detection of building materials has gradually attracted the attention of building materials manufacturers, while the hardness detection of bricks is still blank. Most manufacturers basically introduce hardness testers for detecting metal workpieces into laboratories as substitutes. Bricks are ordinary clay bricks. Their main raw materials are silty or sandy clay. Their main chemical components are SiO2, Al2O3, Fe2O3 and crystal water. Due to different geological formation conditions, they may also contain a small amount of alkali metals and alkaline earth metal oxides. Artificial small blocks used in construction are divided into sintered bricks (mainly clay bricks) and unsintered bricks (lime sand bricks, fly ash bricks, etc.), commonly known as bricks. The product quality of bricks must be qualified, and they should be tested before use. There must be a factory quality certificate and a test report. Before use, sampling tests should be carried out according to different varieties, specifications, origins, and batches.

[0003] After searching, the Chinese patent application number 202121271344.8 discloses a building material hardness detection device, which relates to the field of hardness detection technology. Its structure includes a bracket, a bridge box and a workbench arranged on the upper side of the bracket, the bridge box is arranged above the workbench, and a hydraulic cylinder is vertically installed on the lower side of the bridge box. A pressing plate is horizontally installed on the telescopic end of the hydraulic cylinder, and the workbench is slidably detachable and installed with a collection box. A leakage net leading to the lower collection box is installed in the middle of the workbench. The bricks placed on the workbench are mainly squeezed by a pressing plate and a pressing block. The pressing plate is mainly used for extrusion detection from the upper side of the bricks, and the pressing blocks on both sides of the workbench can mainly be used for extrusion detection from both sides of the bricks. This not only greatly improves the accuracy of the detection data of the bricks, but also can be used flexibly. Moreover, the broken bricks can be pushed into the middle of the leakage net and fall into the collection box for collection under the pushing action of the pressing blocks on both sides, which is not only convenient to use, but also greatly improves the cleaning effect of the broken materials and improves work efficiency.

[0004] The above patent still has the following deficiencies during use: although the device can clean broken bricks, in actual application, since a through hole is opened on the top of the workbench for placing the leaking net, the bricks cannot be completely placed on the top of the workbench, and part of the bricks are above the through hole and suspended in the air. Due to the reduction of the supporting surface, the pressure on the non-suspended part of the brick will increase, which will have a serious impact on the detection data and there are major defects.

[0005] Therefore, a building material hardness testing device is urgently needed to solve the above problems. Utility Model Content

[0030] Specifically, when the building material hardness testing device is in use: the brick to be tested is placed at the center position of the two groups of bearing plates 13, and the brick is made to correspond to the second extrusion plate 25 and the first extrusion plate 32, the hydraulic cylinder 24 and the driving motor are started, the hydraulic cylinder 24 drives the second extrusion plate 25 to perform an extrusion test on the brick from the top, and the test data is displayed on the display controller 54, and at the same time, the driving motor drives the double-threaded screw 23 to rotate, thereby driving the two groups of sliding members 3 to approach each other, and performing a pressure test on the brick through the support rod 31 and the first extrusion plate 32.

This solves the problem that the brick cannot be completely placed on the top of the workbench, and part of the range is above the through hole and is suspended. Due to the reduction of the supporting surface, the pressure on the non-suspended part of the brick will increase and have a serious impact on the detection data, which greatly improves the accuracy of the detection.
