Description
Technical field
The utility model belongs to civil engineering testing inspection instrument technical field, more particularly to a kind of fast temperature shrinks and surveyed
Determine instrument.
Background technology
At present, for concrete sample dry out caused by deformation, and test specimen temperature deformation determines, it will complicated
It is more, be mainly reflected in cement concrete dry contraction tester also due to temperature change and deform, existing cement concrete
Drying contraction tester can not test concrete sample in the case of alternating temperature well, and test result is in the temperature difference
Under big environment, error is larger.
In summary, the problem of prior art is present be：Existing cement concrete dries contraction tester can not be fine
Concrete sample is tested in the case of alternating temperature, and test result, under the big environment of the temperature difference, error is larger.
The content of the invention
The problem of existing for prior art, the utility model provide a kind of fast temperature contraction tester.
The utility model is achieved in that a kind of fast temperature contraction tester includes Test bench, Test bench
Upper surface is uniformly placed with some smooth Circular glass rods, and the upper ends of light Circular glass rod have test specimen；
The both ends of Test bench are symmetrically installed with magnetic force bearing, and the upper end of magnetic force bearing is symmetrically installed with to match with test specimen
Amesdial.
Further, the surface of the Test bench, which is bolted, is provided with track, and light Circular glass rod is fixedly mounted on
In track.
Further, the surface of the smooth Circular glass rod is provided with graduated scale.
Further, the bottom of the magnetic force bearing is provided with sucker, and magnetic force bearing is arranged on test base by sucker suction
On seat.
Further, the amesdial uses pointer gauge.
The advantages of the utility model and good effect are：The fast temperature contraction tester can adapt to it is arduous under the conditions of
Road construction site measures, detection process is simple, stably, it is convenient, fast；By the popular welcome of technical staff；Road is built
The measure of material temperature deformation is built, to control and examine the ability of ground surface material resistance temperature deformation cracking that there is extraordinary inspection
Survey effect.
Brief description of the drawings
Fig. 1 is the structural representation for the fast temperature contraction tester that the utility model embodiment provides；
In figure：1st, Test bench；2nd, light Circular glass rod；3rd, magnetic force bearing；4th, amesdial；5th, test specimen.
Embodiment
For invention, features and effects of the present utility model can be further appreciated that, following examples are hereby enumerated, and coordinate
Accompanying drawing describes in detail as follows.
1 pair of structure of the present utility model is explained in detail below in conjunction with the accompanying drawings.

Glass bar 2, the upper ends of light Circular glass rod 2 have test specimen 5；
The both ends of Test bench 1 are symmetrically installed with magnetic force bearing 3, and the upper end of magnetic force bearing 3 is symmetrically installed with and the phase of test specimen 5
The amesdial 4 of matching.
Further, the surface of the Test bench 1, which is bolted, is provided with track, and light Circular glass rod 2 is fixedly mounted
In orbit.
Further, the surface of the smooth Circular glass rod 2 is provided with graduated scale.
Further, the bottom of the magnetic force bearing 3 is provided with sucker, and magnetic force bearing 3 is arranged on test by sucker suction
On pedestal 1.
Further, the amesdial 4 uses pointer gauge.
Operating procedure of the present utility model is as follows：
1st, ground surface material test specimen 5, including bitumen mixture specimen 5 (4cm × 4cm × 20cm), the semi-rigid material of basic unit are made
Expect (10cm × 10cm × 40cm or 5cm × 5cm × 25cm), it would be desirable to which the test specimen 5 of health, health to desired age are accurate
Standby experiment；
2nd, by ready test specimen 5, it is placed under defined temperature environment (- 30 DEG C, -20 DEG C or -10 DEG C), until
The constant temperature of test specimen 5；
3rd, test specimen 5 is placed on the light Circular glass rod 2 of Test bench 1, placing the purpose of glass bar there are two, first, energy
Enough move the Free Transform of test specimen 5, second, thermal insulation, avoids pedestal from being influenceed deformation by temperature；
4th, magnetic power meter bearing is placed on the both ends of test specimen 5, amesdial 4 is laid on bearing；
5th, initial reading is read, and determines current environmental temperature, when the constant temperature of test specimen 5 to environment temperature, then reads thousand points
The reading of table 4；
6th, result of the test is carried out
Result of the test process：
△ ε --- temperature deformation coefficient
D2 --- during test specimen constant temperature to environment temperature, reading the reading of amesdial 4 (mm)
D1 --- take initial reading (mm)
L --- piece lengths (mm)
T2 --- current environmental temperature
T1 --- under defined temperature environment (- 30 DEG C ,-20 DEG C or-10 DEG C)
2nd, test result analysis
When △ ε are larger, illustrate that material temperature sensitiveness is big, as pavement construction material, be affected by temperature big；
It is small for temperature change sensitiveness when △ ε are smaller, it is more beneficial for as pavement construction material.
Described above is only to preferred embodiment of the present utility model, not the utility model is made any formal
Limitation, it is every according to the technical essence of the utility model to any simple modification made for any of the above embodiments, equivalent variations with
Modification, is belonged in the range of technical solutions of the utility model.
