Description
Technical field
It the utility model is related to a kind of hot test displacement tester.
Background technology
During high temperature load test is carried out to concrete sample, it is thus necessary to determine that and two important parameters of measurement, i.e., it is warm
Degree and displacement, to obtain the relation of temperature-displacement.The method of measuring temp has many kinds, such as nickel chromium-nickel silicon thermocouple measurement
Deng.Temperature level can be monitored in real time during experiment and easily realize and solve.
But while heating to concrete sample, it effectively can not easily observe displacement, and hot test
Decrepitation Phenomena can occur for the higher concrete of middle intensity, it will make dial gauge, amesdial for directly being contacted in experiment with component etc.
Strong concussion can occur for test instrumentation reading so as to cause result of the test serious distortion, increase the error of experimental result, be unfavorable for
The progress of follow-up study work.
The content of the invention
In order to solve the above-mentioned technical problem, the utility model provides a kind of displacement tester so that device tries in high temperature
Displacement measuring instrument in testing will not be contacted directly with component, it may ensure that the accuracy of experiment, improves the essence of experimental result
True property.Compared with other displacement testers, make simply, cost is low, easily realizes.
The technical solution adopted in the utility model is：Including steelframe, fixed mount, a string formula displacement meter, fixed pulley, thin steel
Silk, weight and expansion bolt.A described string formula displacement meter is arranged on fixed mount；Described fixed pulley is arranged on steelframe；
Described expansion bolt is joined directly together by drilling with component；Described finer wire is wrapped on expansion bolt, passes through nut pressure
Tightly；Finer wire bypasses fixed pulley, through after displacement meter, and hangs up weight；Change in displacement at described expansion bolt is by thin steel
Silk is delivered to a string formula displacement meter by fixed pulley.
In above-mentioned displacement tester, described rigid frame is made up of round steel or steel pipe.
In above-mentioned displacement tester, described finer wire for it is a kind of with certain tensile strength and 150 DEG C with
Lower thermal coefficient of expansion is smaller.
In above-mentioned displacement tester, a described string formula displacement meter uses a kind of digital displacement meter, so as to
Automation collection is carried out to experimental data.
Due to being had the following advantages that using said structure, the utility model：
The utility model is simple in construction, and cost is low；The utility model uses digital string formula displacement meter, and its data can be with
Real-time Transmission is carried out by data wire, is advantageous to dynamic measuring and the below analysis of experimental data；The utility model uses
Finer wire one end connecting elements, the other end are suspended in midair with weight by being connected after two fixed pulleys with displacement meter, thus solved
Reading concussion problem；The utility model employs heat-insulated, Insulation to steel wire, can effectively control the thermal expansion of steel wire
Rate.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described further below in conjunction with the drawings and specific embodiments.
As shown in figure 1, this experiment is new including expansion bolt 1, finer wire 2, fixed pulley 3, steelframe 4, a string formula displacement meter
5th, weight 6 and fixed mount 7.A described string formula displacement meter 5 is welded on fixed mount 7；Described fixed pulley 3 is welded on steelframe 4
On；Described expansion bolt 1 is joined directly together by drilling with component；Described finer wire 2 is wrapped on expansion bolt 1, is passed through
Expansion bolt nut compresses；Finer wire 2 bypasses fixed pulley 3, through after a string formula displacement meter 5, and hangs up weight 6.
This experiment determines the change of the amount of deflection of component using digital string formula displacement meter, and concrete mode is in component measuring point
Embedding expansion bolt, covers heat insulation foam again thereon at the concrete surface of position, and one end of finer wire is screwed into nut, another
Suspended in midair by being connected after two fixed pulleys with a string formula displacement meter with weight at end.So, a whole set of displacement tester and component
It is connected as a single entity, it is possible to solve reading concussion problem well, there is certain tensile strength and at 150 DEG C additionally, due to steel wire
Following thermal expansion is smaller, plus appropriate heat-insulated, Insulation is employed during experiment, so as to ensure that displacement measurement numerical value
Reliability.In order to ensure the reliability of test result, multiple demarcation has been carried out to test instrumentation before and after whole experiment.
