Description
Technical field
This utility model belongs to Experiments of Machanics apparatus, is specifically related to a kind of experiment clip surveying rubber and concrete peel strength
Tool and test structure.
Background technology
One of compressed-air energy storage power station sealing means is to use flexible sealing material to carry out close to zawn gas storage
Envelope, vulcanite was once applied to external construction of storage due to tensile property excellence, peel strength direct reaction rubber with
Adhesion strength size between concrete, these data are to judging that needed for sealing grotto gas storage, the thickness of vulcanite has important
Effect.
On the one hand, the domestic underground natural gas storage tank that there is no by zawn sealing air, so vulcanite and concrete
Between adhesive strength the most how, need what kind of adhesive to there is no any experimental data.On the other hand, although rubber
A related specifications is had with the peel strength of other hard plate material, but due to relatively thin, the thinnest concrete slab of concrete slab in specification
Tensile testing machine is easy to brittle failure.If using thicker concrete slab, do not have again suitable fixture can clamp sample,
It is made to test on puller system.Can be by concrete slab it is crucial that use existing method for normalizing to survey concrete peel strength
Marginal laceration so that test is not the stripping interfacial failure at concrete, causes measuring peel strength.
Utility model content
For the problems referred to above, this utility model aims to provide a kind of being applicable to and measures the new of rubber and concrete peel strength
Type laboratory holder, this fixture can measure peel strength accurately.
This utility model solves the technical scheme of problem: a kind of laboratory holder surveying rubber and concrete peel strength,
Including the closed enclosure flask body for casting concrete sample, this box body top is the most unlimited, and box body top covers and fixes
Size is had to be more than the clamping plate of box box body；
The position of described clamping plate correspondence box box body top open ports has through hole, and this clear size of opening is less than box box body
The size of top open ports, the through hole edge on this clamping plate stretches out one section relative to box box body top open ports to inner side
Suspending part.
In such scheme, why clear size of opening is less than the size of box box body top open ports, is in order to suspending part
Push down the marginal portion of concrete sample, with prevent when doing rubber and concrete disbonded test concrete edge draw bad, tear
Split, be the stripping interfacial failure at concrete with guarantee test.
Further, described clamping plate lower surface flatness error is not more than 1.5mm.Its purpose is to so that fixture exists
Can try one's best after Gu Ding level.Otherwise, if pulling force and bond area exist certain angle, it is to pull open sideling the when of stripping, and not
It is that same cross section is opened, eccentric force can be produced, cause the peel strength recorded less than normal.
Preferably, described clamping plate is provided with the bolt hole for being fixed on tensile testing machine by clamping plate.
Preferably, described clamping plate lower surface is welded and fixed with box body intersection.
Meanwhile, this utility model also provides for laboratory holder survey rubber and concrete stripping described in a kind of application such scheme by force
Degree test structure, it is characterised in that: fill up the concrete sample poured in described box body, the upper surface of this concrete sample with
The lower surface contact of suspending part, the concrete upper surface in via regions is coated with adhesive, adhesive is bonded with rubber,
One section of unbonded bare terminal end for clamping is left in one end of this rubber.
In a kind of concrete experimental program, described bare terminal end keeps vertical with bond area all the time.This kind of scheme is used for testing
90 ° of peel tests.
In another kind of concrete experimental program, described bare terminal end keeps antiparallel with bond area all the time.This kind of scheme is used
In 180 ° of peel tests of test.
During experiment, first, casting concrete sample in box body；
Then, smear adhesive, by rubber and concrete sample full bond.When smearing concrete adhesive, should keep
Adhesive surface is clean, it is to avoid the pollution to adhesive surface of dust, dampness and external substance.
Afterwards, the fixture assembled is put on the testing stand of tensile testing machine, and Boards wall, rubber and pulling force will be filled
The upper grip of machine connects.In whole experimentation, the direction of pull of stripping is caused to keep presetting with concrete bond area all the time
Angle.Opening tensile testing machine, speed is 50mm/min ± 5mm/min.Until rubber is separated completely with concrete sample,
Record peeling force.
Remarkable result of the present utility model is:
It is convenient that the most simple and reasonable, experimental implementation is strong, the sample later stage processes, it is possible to ensures surveying peel strength process
Middle concrete edge is not drawn bad, tear so that test is the stripping interfacial failure at concrete, thus measures and peel off accurately
Intensity.
2. the design of clamp structure so that can pour the concrete sample that thickness is big, clamping plate still can fixation clamp
Hold.The concrete sample solving conventional brace thin is fragile, the technical problem that the concrete sample that thickness is big can't clip.
