At present according to national standard《Standard for test methods of mechanical properties of ordinary concrete GB/T50081-2002》In be directed to coagulation
The test fixture required in native tensile splitting strength method for measuring, specification is not provided with test specimen levelling device due to bottom plate, in examination
Time during testing needed for test specimen pair is longer, significantly reduces test efficiency.The fixture seaming chuck is not solid simultaneously
Determine device, the problems such as easily seaming chuck deflection occur in process of the test.In addition, frequently encountering pressure when test specimen is damaged by pressure
Head drops or snapped on support, and test operation is inconvenient.Because the presence of problem above influences whether that experiment is surveyed to a certain extent
The precision of amount.
Due to different specification《Concrete for hydraulic structure testing regulations SL352-2006》And《Concrete for hydraulic structure testing regulations DL/
T5150-2001》In for concrete splitting tensile strength to determine used experiment loads fixture different.Therefore,《It is general
Logical mechanical performance of concrete test method standard》The concrete splitting tensile test fixture of middle requirement can not be directly applied to《Water
Work concrete test code》In, it is necessary to change test fixture.The presence of disadvantages described above causes the use model of traditional test fixture
Enclose and more limit to.
The content of the invention

Present invention has the advantages that：
1. the present invention can rapidly and accurately measure concrete splitting tensile strength values, it is suitable for various sizes of cube
Or cylinder concrete test block, the rubber filler strip 9 of setting, substantially reduce the position adjustment to concrete test block in process of the test
Time, and then can conveniently and efficiently carry out the measure of concrete splitting tensile strength.
2. the upper bearing plate connection of fixture, can be adsorbed onto on the top board of testing machine, can not only subtract by the setting of magnetic sheet 8
The error for the concrete splitting tensile strength values that few pressure head weight is caused, improves the accuracy of measured value, while being completed in experiment
Afterwards can during lifting test machine top board the together upper bearing plate of lifting clamp, process of the test is convenient and swift.
3., can be more into draw and insert-type for the pressure head form design of test fixture according to the requirement of different concrete test specifications
The Multifunctional pressure head changed, can meet in different specification under conditions of only adjustment replaceable pressure head and be directed to test fixture requirement not
Same purpose.The use scope of the Split-tension of Rolled fixture is greatly expanded.Suitable for the different majors such as building, water conservancy project, different works
The use of the Split-tension of Rolled fixture has greatly been expanded in journey field for the different requirements of concrete splitting tensile strength assay method
Scope.
4. lightweight construction of the present invention, easy to operate.
