Description
Technical field
The utility model belongs to highway stabilized with inorganic binder material tests its physics, the field of mechanical property, specifically relates to
And a kind of facilitate the cushion block of sample preparation for inorganic binder unconfined compression strength test.
Background technology
With developing rapidly for civil engineering industry, in engineering it is increasing using inorganic binder come stabilized base,
Underlayment etc., it does not only have good Physical and mechanical properties, and has energy-saving, the effect of environmental protection.Using process
In in order to be better understood by the performance of various stabilized with inorganic binder materials, it is necessary to be examined by testing, and without lateral spacing resistance to compression
Intensity is exactly the index that one of which examines mechanical property.Find that the forming method of test specimen is present during doing experiment
Problem, and whether sample dimensions can accurately influence the accuracy of result of the test, and then be unfavorable for guiding construction.
When making inorganic binder unconfined compressive strength test specimen, often there are problems that three：(1) in testing regulations
Regulation feeds the exposed 2cm of lower lock block, and this process is in operation it is difficult to ensure that exposed accuracy of gauge.After sample shaping,
Need to check height of specimen whether in the range of error 1-2mm, if being unsatisfactory for code requirement needs to remake sample.This
Place's height of specimen whether exist in error range with the exposed accuracy of gauge of upper lower lock block it is larger contact, if briquetting expose compared with
Many, specimen height is higher than desired height, if briquetting exposes less, specimen height is more relatively low than desired height.(2) exist
《JTGT F20-2015 highway road surface construction technology detailed rules and regulations》Provided in new order, at present using medium-sized (100mm*100mm)
Die trial and large-scale (150mm*150mm) die trial make sample, and die trial is larger, heavier, after certain sample is loaded in die trial again
Then total quality will be heavier.At present during doing experiment, if without this cushion block, need someone hold in the palm whole mould or
Various instrument pads are found to feed.It is unfavorable for ensureing accuracy and the control of loading characteristic of specimen size.(3) if will examination
Mould is placed on smooth desktop, after sample is installed, puts upper holder block well, is picked up whole die trial from desktop and is carried to pressure
During machine, because bottom and desktop are closely connected, therefore it is difficult to pick up.Therefore, current unconfined compressive strength lacks one kind in sample preparation just
In the Multifunctional cushion block of sample preparation, help out, be conducive to easily and efficiently sample preparation.
Utility model content
In order to overcome prior art not enough, the purpose of this utility model is to provide a kind of inorganic binder that is used for without lateral spacing
Compressive strength test facilitates the cushion block of sample preparation, can improve the accuracy of sample dimensions.
The utility model, which is adopted the following technical scheme that, to be achieved：
A kind of to be used for the cushion block that inorganic binder unconfined compression strength test facilitates sample preparation, cushion block is three layers of stairstepping,
It is divided into lower floor's step, middle level step, upper strata step；Lower floor's step radian is identical with middle level step radian, and upper strata step radian is r
=88mm-90mm；Lower floor's shoulder height is 30mm-50mm, and lower floor's step width is 30mm-50mm；Middle level step width is
15mm-30mm；Upper strata shoulder height 20mm-40mm, upper strata step width is 30mm-50mm.
Four cushion blocks are symmetrically and evenly arranged in cross.
Lower floor's step radian is r=75-80mm with middle level step radian.
Middle level shoulder height is 20mm.
Technique effect of the present utility model：
When the utility model solves test material preparation in the prior art, the accuracy of sample dimensions is not high, and test specimen is by upper
When lower lock block is extruded the problem of unbalance stress；Solve because die trial and sample mass are too heavy, be unfavorable for the problem of personnel move.
It is fast, effective to improve sample preparation efficiency by using this cushion block in process of the test so that simple to operate.

Embodiment
The utility model is described in further details below in conjunction with the accompanying drawings.
The utility model cushion block is three layers of stairstepping, is divided into lower floor's step, middle level step, upper strata step；Lower floor's step arc
Degree is identical with middle level step radian, and upper strata step radian is r=88mm-90mm；Lower floor's shoulder height is 30mm-50mm, lower floor
Step width is 30mm-50mm；Middle level step width is 15mm-30mm；Upper strata shoulder height 20mm-40mm, upper strata step is wide
Spend for 30mm-50mm.
Four cushion blocks are symmetrically and evenly arranged in cross.
Lower floor's step radian is r=75-80mm with middle level step radian.
Cushion block is placed on smooth ground or desktop by the utility model, and lower lock block is placed on lower floor's step.Will examination
Die sleeve is on lower lock block and is placed on the step of middle level.Vexed good soil sample is divided 2-3 times and poured into die trial, is gently uniformly inserted with rod is rammed
In fact and specimen surface is smoothed, briquetting is put in sample top surface.Stayed with hand rest the bottom of briquetting and die trial, by lower lock block, examination
Mould, upper holder block, which are integrally removed, carries out sample preparation to forcing press.
It will be placed on as we can see from the figure with 8 identical lower lock blocks on lower floor's step 1 of cushion block 11, middle level step 2 is high
For 20mm, need exposed size identical with specification, therefore sample preparation people need not consider whether exposed size is sufficient when making sample
Enough, whether briquetting moves during sample is filled, and this process substantially increases the speed and precision of sample preparation.Die trial 9 is enclosed within down
On briquetting, die trial, so height of the briquetting in die trial is also 20mm, should be placed on middle level step 2 by the total high 40mm of briquetting, under
Layer step and middle level step are the radius d=75-80mm of isocentric circular arc 4, and the lower floor's step radian than in of upper strata step radian 5 is bigger,
Its radius is d=88-90mm.To ensure its stability, the width 15-30mm of middle level step 2, it is adaptable to medium-sized and large-scale die trial
Place.Vexed good soil sample is divided 2-3 times and poured into die trial, the surface of sample 10 is smoothed, upper holder block 8 is placed and simultaneously ensures upper holder block 8
Also exposed 20mm is wanted.After each several part is assembled, it can be seen that have 30-50mm between lower lock block and smooth ground or desktop
Spacing, hand can be stretched into spacing, by lower lock block, upper holder block 8, die trial 9, sample 10 it is overall remove make to forcing press sample into
Type.This process improves sample preparation efficiency, the degree of accuracy of size and uniform force.Cushion block is in the cross surrounding for being arranged in die trial,
Ensure the stability of die trial in sample making course.
