Description

Technical Field

[0001] This utility model relates to the field of grout testing technology, specifically to a joint testing device. Background Technology

[0002] The cohesiveness of grout refers to the bonding ability between particles and the overall strength after solidification. The cohesiveness of grout is related to its reinforcement effect and durability in practical applications, and is an important indicator for evaluating the performance of grout.

[0003] The cohesion test of existing grouting materials is generally conducted by rubbing the grout. When testing the cohesion of the grout in this way, the grout being tested is subject to a lot of external forces, which leads to deviations in the test results and affects the judgment of the cohesion on the grout's performance. Utility Model Content

[0004] Based on the above description, this utility model provides a cohesion testing device to solve the problem that the test results are prone to deviation when the cohesion of existing grouting materials is tested by friction.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a unity testing device, including a tensile tester, a measuring cup is installed on the outside of the tensile tester, a tension member is threadedly installed on one end of the tensile tester, the tension member overlaps with the measuring cup, and moves vertically back and forth along the measuring cup.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the tensile tester includes a test platform, a force gauge, and a knob. The test platform is in the shape of a right angle and the lengths of its two ends are not equal. The force gauge is slidably connected to the longer end of the test platform and to the side near the included angle. The knob is rotatably connected to the outside of the longer end of the test platform.

[0008] Furthermore, a threaded groove is provided at the center of the shorter end of the test platform, near the included angle, and the axis of the threaded groove coincides with the center of the force gauge.

[0009] Furthermore, one end of the measuring cup is provided with an external thread and is threaded into the threaded groove.

[0010] Furthermore, an inner connector is fixedly connected to the center of the force gauge near the measuring cup. The inner connector is a threaded connector, and an outer connector is threaded to the inner side of the inner connector.

[0011] Furthermore, the tension member is fixedly connected to the end of the external connector away from the force gauge, and the axis of the tension member coincides with the axis of the external connector.

[0012] Furthermore, the stretching member extends to the inside of the measuring cup, and the stretching member is cylindrical.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0014] This invention uses a tensile tester and a tensile component, along with a measuring cup. A force gauge drives the tensile component to fuse and separate with the grout sample in the measuring cup to test the cohesion. The tensile component remains vertical throughout its movement, so the test results are less affected by external forces. The process is simple and ensures the accuracy of the grout cohesion test results. Attached Figure Description

[0020] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0022] Please see Figure 1-3 The present invention provides a joint strength testing device, including a tensile tester 1, a measuring cup 6 mounted on the outside of the tensile tester 1, and a tension member 4 threadedly mounted on one end of the tensile tester 1. The tension member 4 overlaps with the measuring cup 6 and moves vertically back and forth along the measuring cup 6.

[0023] Please see Figure 1 The tensile tester 1 includes a test platform 11, a force gauge 12, and a knob 13. The test platform 11 is in the shape of a right angle and the lengths of the two ends are not equal. The force gauge 12 is slidably connected to the longer end of the test platform 11 and to the side near the included angle. The knob 13 is rotatably connected to the outside of the longer end of the test platform 11. The model of the tensile tester 1 is HH-8720A. The knob 13 can adjust the force gauge 12 to slide vertically along the surface of the test platform 11.

[0024] Please see Figure 2 The test platform 11 has a threaded groove 5 at the center of the shorter end and the side near the included angle. The axis of the threaded groove 5 coincides with the center of the force gauge 12. The outer end of the measuring cup 6 has an external thread 61 and is threaded into the threaded groove 5. The measuring cup 6 can be fixed by the threaded connection. When the tension member 4 is fused and separated from the grout sample inside the measuring cup 6, the fixed measuring cup 6 cannot be moved by external force, thus avoiding the impact on the cohesion test of the grout sample. At the same time, the threaded connection simplifies the fixing and disassembly of the measuring cup 6 and facilitates the cleaning and recycling of the measuring cup 6.

[0025] Please see Figure 2 The force gauge 12 is fixedly connected to the center of the end near the measuring cup 6 with an inner connector 2. The inner connector 2 is a threaded connector. The inner side of the inner connector 2 is threadedly connected to an outer connector 3. Both the inner connector 2 and the outer connector 3 are threaded connectors, which facilitates the disassembly and installation of the tensioning component 4.

[0026] Please see Figure 1 The tension member 4 is fixedly connected to the end of the outer connector 3 away from the force gauge 12. The axis of the tension member 4 coincides with the axis of the outer connector 3. The tension member 4 extends to the inner side of the measuring cup 6. The tension member 4 is cylindrical. The cylindrical tension member 4 can ensure that the force is uniform when in contact with the grout sample. When the tension member 4 enters the measuring cup 6, the grout sample can be added into the measuring cup 6 so that the grout sample is evenly filled between the measuring cup 6 and the tension member 4 and the inner side of the tension member 4. When the test platform 11 moves the tension member 4 out of the measuring cup 6, the tension member 4 will be affected by the viscosity of the grout sample, which will increase the force on the force gauge 12 and display the force on the force gauge 12. The operator can test the cohesion of the grout sample by observing the value on the surface of the force gauge 12.
