A device and test method for detecting shear strength of composite steel plate

Abstract

The invention relates to a device and a test method for detecting the shear strength of a composite steel plate, belonging to the technical field of metal material detection. It includes a pressure plate assembly (1), a cover plate (2) and a test platform (3) that are contacted and connected in sequence, and the test platform (3) includes a left clamp block (33), a platform body (37), a right clamp block (36), a right clamp block (36), and a left clamp block (33). The clamp (34), the handle (35), and the rotating handle (35) can adjust the distance between the right clamp block (36) and the left clamp block (33), so that the sample (32) is located between the right clamp block (36) and the left clamp block Between (33), the horizontal positioning of the sample (32) is realized. The sample (32) of the device and the axial force of the testing machine are on the same straight line, and at the same time, the instantaneous force can be effectively prevented from being too large, and the real test result can be obtained. The solution is to solve the problem that the instantaneous force of the contact between the sample (32) and the pressing plate caused by the prior art is too large, and the sample (32) and the axial force of the testing machine are not on the same straight line, thereby causing the test result to be distorted.

Description

technical field [0001] The invention relates to a device and a test method for detecting the shear strength of a composite steel plate, belonging to the technical field of metal material detection. Background technique [0002] Composite steel plate is a composite plate based on steel. Because of its good characteristics, it is widely used in marine, petrochemical, electric power and other fields. [0003] The performance detection of clad steel plate is particularly important for the further development of clad steel plate. In the performance testing of composite steel plates, the shear strength is an important index, which is to determine the shear resistance of the joint surface between the base material and the composite material. The national standard stipulates that the total thickness of the clad steel plate is greater than 10mm, and the shear test is carried out with the compression shear specimen. At present, in the market, there are relatively few devices for mea...
