The utility model discloses a simple device for testing the tensile and shearing strength of cementing compound; including two pegs (4) with a round handle (5) and two chucks connected with an upper and a lower clamp fasteners. A chuck cap (3) is connected with chuck side walls (2) which are provided with a chuck side wall hole (1). The pegs (4) are vertically connected with the round handles (5). Material adopts 45 carbon steel. The chuck cap (3) is engraved with threads. The distance between the two chuck side walls (2) is greater than the thickness of the steel plate to be tested by 0.2 to 0.5 cm. The diameter of the hole (1) of the chuck side wall (2) is greater than the diameter of the peg (4) by 0.2 to 0.4 cm. The length of the peg (4) is greater than the distance between the two chuck side walls (2) by 0.1 to 0.2cm.

Description
Technical field
The utility model relates to a kind of easy device that the tackifier tensile shear strength is measured that is used for.
Background technology
The method of test tackifier tensile shear strength is carried out with reference to GB GB7124-1986 at present.According to the tensile shear strength of this GB specimen on common puller system or electronic universal tester, owing to the design of puller system or electronic universal tester clamper itself exist systematic error cause survey that to draw sample to stretch shear resistance inaccurate., analyze wherein former because the lines that the inside surface of the upper and lower holder of puller system has the sample that prevents to be tested to skid when test.Before the specimen, when clamping sample and then using the clamp holder clamping sample, because the influence of last clamper inside surface lines always makes sample be subjected to the upwards slight acting force that stretches with lower gripper; Otherwise, when using the clamp holder clamping sample and then clamping sample, because the influence of lower gripper inside surface lines always makes sample be subjected to the slight upwards effect on top with lower gripper.When upper and lower holder clamped sample, sample inevitably was subjected to the effect of a mechanical external force before test, that is to say no matter to adopt what order clamped sample, all can not change sample kept not being subjected to extraneous mechanical force before test effect; In addition, if under high temperature or cryogenic conditions specimen because expanding with heat and contract with cold of tackifier and steel plate adds that specimen is fixed on the upper and lower holder, thereby it is more obvious to make that sample is subjected to the effect of mechanical external force.Just because of the error in the said equipment system, thereby cause the measurement result of institute's specimen to be greater than or less than actual measured value; In addition, because puller system or electronic universal tester lower gripper are fixed, can freely swing and go up clamper, in the clamp holder clamping sample test, always make that the center line that is subjected to force direction and sample of sample is inconsistent, even adopt other method calibration, all can exist testing efficiency low, the test result problem of unstable.
Summary of the invention
The purpose of this utility model is at present mensuration tackifier tensile shear strength because the weak point of clamper design provides a kind of and the matching used device of upper and lower holder.This device not only can be avoided the effect of the mechanical external force of sample before test, and can guarantee very easily that the sample of being tested is subjected to force direction consistent with the sample center line.Use this device not only can improve the precision of specimen tensile shear strength, and can greatly improve the efficient of specimen.
The utility model comprises: the pin of two band round handles, two chucks that are connected use with upper and lower holder.Pin vertically links to each other with round handle; Chuck is made up of chuck cap, chuck sidewall, on two sidewalls of chuck hole is arranged respectively.Its material is all selected 45 carbon steels for use, and wherein part (chuck cap) outside surface that stretches out of chuck has the thread line, can guarantee when clamper is clamped chuck non-slip.
Make a call to a circular hole on the steel plate that specimen is used, the requirement of beating circular hole must guarantee (need not adjust direction of pull and sample center line in the time of guaranteeing in specimen like this on the center line of metallic bone face, and in the process of test, along with the increase gradually of the suffered pulling force of sample can be adjusted sample automatically and makes that direction of pull is consistent with the sample center line) and the circular hole size be greater than 0.2～0.4 centimetre of the diameter of pin and consistent with the chuck areole hole dia size of chuck sidewall, to make things convenient for pin freely to insert and to take out; The length of pin is greater than 0.1～0.2 centimetre of the distance between the chuck sidewall, to make things convenient for pin to insert chuck sidewall hole and to guarantee that sample does not fall down; The chuck cap is put in the upper and lower holder of puller system locking gently (because clamper inside surface and chuck cap all have the thread line, when puller system was exerted oneself, the chuck cap can hold tighter); The steel plate that glues tackifier and accomplish fluently circular hole is put in the middle of two chuck sidewalls of figure one clamper, plugged with the circular hole aligning figure one chuck sidewall hole of steel plate and with pin.Distance between two chuck sidewalls of chuck is greater than 0.2～0.5 centimetre of the thickness of the steel plate that specimen uses, can keep sample freely to put into the chuck sidewall like this, and because certain space operation scope is arranged, can guarantee like this after testing sample, can freely dismantle steel plate.
The utility model is simple in structure, cost is lower, easy to use, easy dismounting, can adapt to the tensile shear strength of testing tackifier on puller system or electronic universal tester fast and accurately.
