Description
Technical field
The utility model relates to non-fragment orbit boss resin construction field, is specially a kind of boss resin-cast body bonding strength test device that is particularly useful for the plate-type ballastless track convex blocking platform.
Background technology
Known, non-fragment orbit is divided into double-block type ballastless track, vertical yoke plate formula non-fragment orbit and unit plate-type ballastless track, wherein the structure of unit plate-type ballastless track is followed successively by roadbed from top to bottom, concrete bed, the bituminous concrete mortar, cell board, between cell board and cell board, be provided with cylindrical concrete boss, be referred to as convex blocking platform, the boss resin is filled between track plate and the convex blocking platform, main effect has two, the one, positioning action, resin material with convex blocking platform limit the track plate in length and breadth to displacement, opposing is in length and breadth to acting force, and transmitted load; The 2nd, vibration-damping function, boss resin provide suitable elasticity and rigidity, can the vertical and horizontal vibration of efficient buffer train, guarantee that track structure has long serviceable life.
When passenger dedicated railway line fragment-free track slab boss resin is constructed, need carry out and concrete bonding strength test at present, guarantee construction quality the resin-cast body.But still do not have ripe pour mass bonding strength test device in the market, fairly simple, coarse method and the device of most of employing detects, and not only operation is inconvenient, and influences the testing result of boss resin-cast body cohesive strength.
Summary of the invention
Problems such as the pick-up unit that the utility model is adopted when solving boss resin-cast body bonding strength test does not have ripe structure, and inconvenient operation and testing result are inaccurate provide a kind of boss resin-cast body bonding strength test device.
The utility model is to adopt following technical scheme to realize: boss resin-cast body bonding strength test device, comprise base, be fixed on the piece fixture on the base, have the test specimen folder mouth that cooperatively interacts with test specimen on the piece fixture, the piece fixture top is provided with and is placed on test specimen folder mouthful interior resin-cast body test specimen position to corresponding pressure head, is connected by the buffering back-moving spring between pressure head and the piece fixture, have on the piece fixture that the voltage supply head moves up and down and with the passage of test specimen folder mouthful perforation.Adopt the utility model structural design, when resin-cast body test specimen is carried out the cohesive strength detection, by giving first downward power of pressure, adjustment through the buffering back-moving spring, power is delivered on the test specimen folder mouthful interior resin-cast body test specimen that is placed on piece fixture by the pressure head end again, detect resin-cast body and concrete cohesive strength, the effect lower edge passage of pressure head power effect outside and buffering back-moving spring moves up and down in the said process; The buffering back-moving spring can be used for adjusting the pressure head pressured state and pressure head is resetted.
In order further to optimize the structure of this test unit, improve its function, the utility model has also carried out following optimal design, be set with the upper end in the described buffering back-moving spring and be fixed on guide pole on the pressure head, have on the piece fixture for guide pole move up and down and with a test specimen folder mouthful duct that connects.Along with moving up and down of pressure head, drive guide pole and move up and down along the duct, the effect of guide pole is to guarantee that pressure head traffic direction in operational process is at vertical direction all the time, can not depart from.
Be provided with adjustable bolt on the described piece fixture and above being positioned at test specimen folder mouth.By adjustable bolt test specimen is fixed in the test specimen folder mouth, guarantees the accuracy of testing result.
Compared with prior art, the utility model is simple in structure, be easy to processing, easy to operate, and be easy to carry about with one, also remove and install easily, problem of difficult is made and removed to fine the solution, effectively guarantee to detect the testing result of cohesive strength technical parameter, had certain popularization value, be particularly useful for the detection of passenger dedicated railway line CRTS I non-fragment orbit boss resin-cast body cohesive strength.
