Abstract
The utility model discloses a special tool for testing bonding strength of concrete test pieces. The special tool comprises a fixed pedestal and a drawing head. The fixed pedestal is a frame body, and can be a rectangular frame formed by four steel plates by means of fixed connection. The bottom of the fixed pedestal is provided with a clamping part for connecting a lower-end clamp of a universal tester, while the top of the fixed pedestal is provided with an opening hole for stretching of the drawing head. A pull bar of the drawing head is used for connecting an upper-end clamp of the universal tester. The opening hole and the head part of the drawing head are matched with each other in shape, and a gap is formed between the inner side surface of the opening hole and the outer side surface of the head part. The special tool can be adapted for the universal tester with any model to perform most of the bonding force tests, and is simple in structure, convenient to manufacture, reliable and safe to use. Moreover, the test pieces suitable for the special tool for testing the bonding strength of concrete test pieces are easy to manufacture.
Description
Technical field
The utility model belongs to the mechanics experimental equipment field, a kind of special tooling of making for using universal testing machine test material bonding strength specifically.
Background technology
The material with excellent adhesive property of current a large amount of epoxy, polyurethane or other classifications comes into operation, and the bonding strength of these materials all is regarded as most important performance index at home and abroad.The bonding force that comprises test test adhesives and concrete surface, steel plate surface and epoxy resin mortar face; Test the bonding force situation of these materials after bonding force situation, the test after a period of time is subjected to water logging and photooxidation resistance through the high cold service of certain regional nature limit.
If directly carry out bonding plane is carried out drawing at engineering site, the destructiveness of this method test specimen also is nonvolatil.
The way that present these material adhesive intensity of test are passed through in the world is to make the mortar specimen of two semicylinders, the material that use will be tested is with right cylinder of the bonding one-tenth of these two semicylinder mortar specimens, do the vertical compression strength test behind the maintenance certain hour, intensity when the test bonding interface destroys is judged the bonding strength of material.Make at present the mould of semicylinder mortar specimen both at home and abroad, it all is the steel pipe with some strength that uses an integral body, use a contour solid semicylinder to fill in the steel pipe, then mortar is poured into moulding, mortar solidifies the rear demoulding becomes the semicylinder test block.This mold releasability is very difficult, and the semicylinder mortar specimen after the demoulding is difficult to guarantee its integrality.Generally all can a small amount of breaking occur in the weakest end, can produce certain impact to test result.Some test specimen also can thoroughly destroy because of demoulding difficulty, can't use.
Generally speaking, present stage, there was following defective in various method of testings: if testing experiment carries out at the scene, process bothers and nonvolatil destruction is caused at scene to be measured; If use the mortar mould of above-mentioned semicylinder, demoulding difficulty then, model is difficult to guarantee integrality, the accuracy that this moment also can't the warranty test result.
Present stage does not also have and can in testing laboratory universal testing machine be tested the special tooling that combine with the concrete sample bonding strength in addition.Universal testing machine can stretch to various materials, compresses, crooked, peel off, the multinomial performance test such as shearing, can show in real time record, print test figure, and have that measurement range is wide, precision is high, respond the characteristics such as fast.
If can will be transferred to the test of concrete sample bonding strength use universal testing machine to carry out special test in the testing laboratory, the convenient more accurately bonding strength data that efficiently obtains then, and can protect engineering site.
Summary of the invention:
Defective for above-mentioned prior art existence, the technical problems to be solved in the utility model provides a kind ofly can finish special tooling to the test of concrete sample bonding strength at test indoor application universal testing machine, and the needed concrete sample of special tooling of test concrete sample bonding strength is made more easy.
In order to solve the problems of the technologies described above the technical solution of the utility model be: the special tooling of test concrete sample bonding strength, comprise fixed pedestal and drawing head, fixed pedestal is a framework, and the bottom of fixed pedestal is provided with clamping part, and the top of fixed pedestal is provided with the perforate that drawing head can stretch into.Clamping part is used for connecting the lower end anchor clamps of universal testing machine.
The rectangular frame of fixed pedestal for being composed of a fixed connection by four block plates.
Drawing head comprises flat head and pull bar, and pull bar is perpendicular to head.Pull bar is used for connecting the upper end-fixture of universal testing machine.
The head of perforate and drawing head is the shape of mutually mating, and is gapped between the outside of the inner edge of perforate and drawing head head.Can allow drawing head stretch into fixed pedestal from tapping.
The clamping part of fixed pedestal bottom is the rod member that is fixedly connected on the fixed pedestal bottom.
When carrying out the bonding strength test, need the clamping part of fixed pedestal bottom is placed universal testing machine lower end anchor clamps and clamping, the pull bar of drawing head places the universal testing machine upper end-fixture and clamps, test block is placed into the hollow part of fixed pedestal, bonds with head and the test block of binding material with drawing head.Start universal testing machine operation test procedure, carry out the test of drawing adhesion.After to be tested the finishing, can unclamp upper end-fixture and remove drawing head, unclamp the lower end anchor clamps and remove fixed pedestal.
The special tooling of test concrete sample bonding strength of the present utility model can be adapted to the universal testing machine of any model, can cooperate universal testing machine to carry out most of bonding force tests.Simple in structure, easy to make, safe and reliable.And the test block that is applicable to the special tooling of this test concrete sample bonding strength is also more easily made.
