The special ruler comprises a ruler body, wherein the ruler body is a rectangular plate, the surface of the ruler body is provided with ten longitudinal scales and twenty horizontal scales, the original point of the longitudinal scale is 0, and the distance between the two adjacent longitudinal scales is 2mm; and the original point of the horizontal scale is 0, and the distances from the horizontal scales to the original point are 2mm*3, 2mm*5, 3mm*3, 3mm*5, 4mm*3, 4mm*5,..., 20mm*3 and 20mm*5. The minimum thickness and the maximum length can be conveniently measured by the longitudinal scales and the horizontal scales of the special ruler disclosed by the utility model. The flaky and elongated particles can be measured by the same ruler, and the special ruler has the advantages of simple structure, convenience and high efficiency in operation, and accuracy of measurement results.
Description
Technical field
The utility model relates to the special ruler of faller gill shape particle content measuring in a kind of asphalt, specifically uses the mensuration of the faller gill shape granule content of the coarse aggregate in asphalt, the cement admixture.
Background technology
National regulation is following to the requirement of coarse aggregate faller gill shape content: 1, at a high speed and Class I highway, faller gill shape granule content is not more than 15% in the compound of its superficial layer, and wherein particle diameter is not more than 12% more than 9.5mm, is not more than 18% below the 9.5mm; In the compound of other levels, faller gill shape granule content is not more than 18%, and wherein particle diameter is not more than 15% more than 9.5mm, is not more than 20% below the 9.5mm; 2, faller gill shape granule content is not more than 20% in the compound of the highway of other grades.
At present, the testing tool of faller gill shape granule content has two kinds in the compound of using always: (1) sheet advises accurate appearance and needle-like is advised accurate appearance, still; When test; The definition of elongated piece and platy shaped particle does not have certain ratio, and the opening size ratio that sheet is advised accurate appearance is 1: 6, but the ratio of gathering materials in fact through this hole also is not necessarily 1: 6; The content of the faller gill shape of measuring in this way that gathers materials is than little many, very inaccurate of truth.(2) vernier caliper: this method accuracy has improved, but needs a slice a slice to survey, and will use vernier caliper measured length and thickness, calculates again, and testing efficiency is low.
Summary of the invention
To defective that exists in the above-mentioned prior art or deficiency; The purpose of the utility model is, a kind of slide calliper rule of measuring faller gill shape granule content in the compound are provided, the utility model through horizontal scale and vertical scale can be easily and effectively mensuration minimum thickness and maximum length; And enough same kind of calliper sheets of ability and elongated piece; Simple in structure, easy and simple to handle efficient, measurement result is accurate.
In order to reach above purpose, the utility model adopts following technical solution:
A kind of special ruler of measuring faller gill shape granule content in the compound is characterized in that, comprises the chi body, and said chi body is a rectangular slab, and vertical scale and horizontal scale are arranged on the surface of chi body; Said vertical scale has 10, and initial point is 0, and distance is 2mm between adjacent two scales; Said horizontal scale has 20, and initial point is 0, and the distance between scale and the initial point is respectively 2mm * 3,2mm * 5,3mm * 3,3mm * 5,4mm * 3,4mm * 5 ..., 20mm * 3,20mm * 5.
Further, the corner of said chi body is provided with through hole.
Further, said chi body adopts transparent material.
Description of drawings
Fig. 1 is the perspective view of the utility model.
Fig. 2 is the floor map on the utility model.
Below in conjunction with accompanying drawing and embodiment the utility model is done further and to be explained.
Embodiment
Like Fig. 1, shown in Figure 2, the special ruler of faller gill shape granule content comprises the chi body in the mensuration compound of the utility model, and said chi body is a rectangular slab, and vertical scale and horizontal scale are arranged on the surface of chi body; Said vertical scale has 10, and initial point is 0, and distance is 2mm between adjacent two scales; Said horizontal scale has 20, and initial point is 0, and the distance between scale and the initial point is respectively 2mm * 3,2mm * 5,3mm * 3,3mm * 5,4mm * 3,4mm * 5 ..., 20mm * 3,20mm * 5.Every other numeral that is carved with of scale is to mark this scale.
During the design of above-mentioned horizontal scale since the ratio of the width of maximum length (or width) direction of faller gill shape particle China regulation coarse aggregate and minimum thickness (or diameter) direction greater than 3 particle.But it is different to consider that different purposes possibly require, so laterally scale has 3 times and 5 times.
Said chi body adopts transparent material, and the corner of said chi body is provided with through hole, and this through hole is used for hanging on the place of being convenient to take after slide calliper rule are finished using.
The utility model is to the principle of work of the mensuration of faller gill shape granule content:
Utilize transversely scale of direction that minimum boundary rectangle technology makes minimum thickness to the particle that possibly be the faller gill shape, observe vertical scale then, judge as requested whether this particle belongs to the faller gill shape.
Use the utility model to judge that the content method and the step of coarse aggregate faller gill shape particle are following:
One, preliminary work
With sample at room-dry to dry tack free, and with inquartation or the division of tripper method to the quality that satisfies table T0311-2 regulation, weighing (m), the grade of sieving into table T031 1-2 defined then is subsequent use.
The required sample minimum mass of table T031 1-2 faller gill shape particle test
| Nominal maximum particle diameter (mm) | 9.5 | 16 | 19 | 26.5 | 31.5 | 37.5 | 37.5 | 37.5 |
| The minimum mass of sample (kg) | 0.3 | 1 | 2 | 3 | 5 | 10 | 10 | 10 |
Two, test procedure
1, with sample divide with desktop on, at first range estimation is chosen near cubical particle, the remaining particle that possibly belong to needle-like (elongated) and sheet (flat).
2, the particle of desire being measured is placed on and becomes a stable status on the desktop; Wherein the maximum length of particle in-plane is L; The full-size of lateral thickness is t, and the particle breadth extreme is that (t＜w＜L), the direction of minimum thickness is scale transversely for w; Observe vertical scale then, the particle of L/t >=3 is chosen respectively as faller gill shape particle.
3, take by weighing the quality m of faller gill shape particle
0, by formula calculate faller gill shape granule content Q=m
0/ m * 100%, wherein Q is a faller gill shape granule content, the qualified for gathering materials of regulation that meet the requirements do not meet code requirement and then gathers materials defective.
The foregoing description only is the preferable example of the utility model; This example has specified the technical scheme and the essential implementation of the utility model; Be not to be that protection domain to the utility model limits; All any simple modification and equivalent structure transformation or modifications of being done according to the utility model spirit all should be encompassed within the protection domain of the utility model.
