Description
Technical field
This utility model is related to the splitting box of laboratory, and especially a kind of many size rock mass cleave box, are mainly based upon one
Planting carries out the instrument of Rock Mechanics Test（RMT-150C rigidity servo test instrument）, it is conveniently used for the splitting examination of different size rock sample
Test.
Background technology
The tensile strength of rock is an important indicator for reflecting mechanical properties of rock, be also rock engineering structure design with
A control parameter in security and stability analysis, the size of Tensile Strength of Rock is not the build-in attribute of rock, and it is by outer
Stress state and temperature, the impact of humidity environment residing for load character, rock.Because rock is the aggregation of mineral grain,
Inside has the defects such as crackle, hole, joint, with obvious anisotropism, causes rock strength generally to exist significantly
Dimensional effect.And the difference of the mineralogical composition, structure and cement due to different rocks, the physico mechanical characteristic thousand of rock is poor
Ten thousand are not, and the dimensional effect of different Tensile Strength of Rock also will be inevitable different.
It is emphasized that this analog material of concrete belongs to quasi-brittle material, Size Effect of Strength is this kind of material
Inherent character.The presence of dimensional effect means that the concrete strength determined by test is no longer the property of material, but relies on
In the parameter of geometrical scale.Therefore research Size Effect of Concrete Strength rule is for the mechanical property for calculating xoncrete structure
Can be most important.
Tensile strength is one of basic mechanical parameter of concrete, is to judge structure crack, brittle break occurs（As sheared
Destruction）Important indicator.Due to more difficult using direct tensile test, test data discreteness is larger, therefore mostly using splitting
Split the tensile strength of tensile test indirect determination concrete.Chinese scholars are entered to the tensile splitting strength dimensional effect of concrete
Go substantial amounts of experimental and theoretical study, but still suffer from some problems.On the one hand it is that existing experimental study has focused largely on examination
Part size is the small-size test piece of 50 mm, and sample dimensions are little, thus can not reflect dimensional effect rule；On the other hand, it is different
Researcher adopt diametral compression test sample type it is different, test boundary condition（Such as filler strip form, width）It is different, cause difference
Test data contrast relative difficulty between researcher.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of many size rock mass and cleaves box, is ensureing position and is answering

With the concordance of size rock-sample initial state, so as to improve the accuracy of test.
To solve above-mentioned technical problem, the technical scheme that this utility model is adopted is：
A kind of many size rock mass cleave box, including outside framework, base plate, inner frame and cover plate, and the outside framework includes outrigger
Body, outer frame body two side is provided with deformeter mounting seat, the first scale and rock sample and holds out against hole, the base plate or inner frame and housing
Frame connects, and is respectively used to be fixed large scale rock sample, small size rock sample.
The outside framework, base plate and inner frame adopt stainless steel material.
Outside framework bottom both sides are provided with locating slot, and corresponding base plate or inner frame are slidably connected and logical with outside framework
Cross card article and snap in fixing hole and locked.
The inner frame includes inner frame body, and inner frame body is adapted with outer frame body inside dimensions, and both sides side wall is provided with and peace
Put the relative connecting hole in hole.
The inner frame is provided with the second scale.
Described each deformeter mounting seat is provided with placement hole and locking hole.
The base plate and inner frame are provided with projection with rock sample contact surface.
A kind of many size rock mass of this utility model cleave box, with following technique effect：
1）, by arranging outside framework, base plate and inner frame, effectively improving carries out replacing different size during diametral compression test
The various step of rock sample, in the case where ensureing that position and deformeter are not transferred, can arbitrarily change the size of rock sample, be
The carrying out of test improves efficiency, it is ensured that the concordance of different size rock-sample initial state, so as to improve the accurate of test
Degree, and it is simple to operate, it is easy to use.
2）, stainless steel material adopted by the material to the device, increased the service life of device, stainless steel material with
Rock sample friction is less, and the impact to rock sample is less.
3）, the device make that simple, cost is less, convenient operating maintenance, it is easy to utilize.

Specific embodiment
As shown in figs 1-9, a kind of many size rock mass cleave box, including outside framework 1, base plate 2, inner frame 3 and cover plate 12, outward
Framework 1, base plate 2, inner frame 3 and cover plate 12 etc. all adopt stainless steel material, which not only adds the service life of device,
Because stainless steel material and rock sample friction are less, the impact to rock sample can be also reduced in addition.The outside framework 1 includes outer frame body 4,
The two side of outer frame body 4 is provided with deformeter mounting seat 5, the first scale 8（First scale is arranged on inside sidewalls wall, convenient to see
Positioning is examined, makes rock sample can be placed at centre position）And rock sample holds out against hole 13（Rock sample holds out against hole for carrying out to different rock samples
Fixation holds out against）.Described each deformeter mounting seat 5 is provided with placement hole 6 and locking hole 7, before the experiments, can pass through placement hole
6 and locking hole 7 by cleave box be fixed on the testing stand of RMT-150C, it is ensured that rock sample will not swing in process of the test.
During work, it is first determined the size of sample, if large scale rock sample is l × w=100mm × 100mm（Or r=50mm）,
First the special base plate 2 of large scale rock sample is slipped into into locating slot 9, the hole on the hole on base plate 2 and outside framework 1 is carried out into para-position, shape
Into after fixing hole 10, by card article（It can be the bar such as latch or iron bar）Insertion fixing hole 10.So ensure outside framework 1 and base plate
2 are fixed together.Then the splitting box for setting is placed on the testing stand of RMT-150C, is placed in the axis of axially loaded piston
Line is defined, then rock sample is placed in splitting box, two deformeters is installed successively and is fixed by locking hole 7, screws split afterwards
The nut that box side rock sample is held out against in hole 13 is split, rock sample is fixed, diametral compression test is subsequently carried out.
The inner frame 3 includes inner frame body 11, and inner frame body 11 is adapted with the inside dimensions of outer frame body 4, can be used for 50mm
×50 mm（Or r=25mm）Rock sample tested.Both sides side wall is provided with connecting hole 14 and second quarter relative with placement hole 6
Degree 15, inner frame 3 is placed, is fixed in outside framework equivalent to a small-sized splitting box.To carry out small size rock sample test, only
Base plate 2 is extracted out in need to testing on, small size rock sample diametral compression test is carried out by changing undersized inner frame 3, so,
The concordance of different size rock-sample initial state is ensure that, so as to improve the accuracy of test.
The base plate 2 and inner frame 3 are provided with projection with rock sample contact surface.Thus structure, can play in cleaving process
The effect of blade, accelerates splitting.
