The utility model solves the technical problems of convenient connection between a reinforcing bar stress gauge and a test pile reinforcing bar and removing weld thermal effect, can be applied to vibrating-wire reinforcing bar stress gauge, and has the advantages of easy installation, high accuracy, fine long-term stability and small temperature influence.
Description
Technical field
The utility model relates to a kind of stress test equipment, particularly a kind of reinforcement stresses testing tool.
Background technology
In the construction of construction work test pile, taseometer need be installed on the reinforcing bar by design attitude, carry out the reinforcement stresses test.The reinforcement stresses meter can be embedded in hydraulic structure or other concrete structures for a long time, the reinforcement stresses of measurement structure inside.Known reinforcement stresses meter comprises taseometer test component and shell, by signal output cable and the supporting use of testing tool main frame.When the inner reinforcing bar of tested structure met with stresses, the reinforcement stresses meter was a frequency signal with stress transmission, after testing tool main frame mensuration frequency, calculated stress according to mathematical models, and directly calculated the demonstration of stress numeral.The reinforcement stresses meter adopts welding connecting mode traditionally with being connected of reinforcing bar.Flash butt welding, single-selded lap joint, group's bar weldering etc. are generally arranged, and these connected modes have following defective: the flash butt welding power consumption is big, the operational quality instability; Single-selded lap joint is an eccentric force, has measuring error; Group's bar weldering operation inconvenience, when bar spacing was nearer, welding operation can't be implemented.More than three kinds of mode workman manipulation strengths bigger, power consumption is more, it is higher to consume energy owing to there is a welding effect, equal damaging stress instrumentation examination parts easily when the operation welding, and construction more complicated.
The utility model content
In order to overcome the deficiency of existing reinforcement stresses meter, the utility model provides a kind of taseometer that is used for the test pile construction, solve reinforcement stresses meter and the convenient technical matters that is connected, eliminates welding effect of test pile reinforcing bar.
The technical scheme that its technical matters that solves the utility model adopts is:
This taseometer that is used for the test pile construction, comprise test component, the testing tool main frame in shell, the shell and be connected test component and the signal output cable of testing tool main frame, it is characterized in that: test component extends two rod iron connecting links to the shell two ends, the end of two rod iron connecting links all is with screw thread, above-mentioned screw thread is identical with a silk specification that is connected reinforcing bar, and both joints are connected by the internal thread coupling sleeve.
Above-mentioned screw thread is identical with a silk rotation direction that is connected reinforcing bar or rotation direction is opposite.
Above-mentioned screw thread can be rolling straight thread or taper thread.
Above-mentioned screw thread can be single thread, double thread or three-start screw.
The beneficial effects of the utility model are:
Be connected with bush whorl between reinforcement stresses meter and the test pile reinforcing bar, preparation of construction and method are simple, connect very convenient, simplified constructing operation, alleviated working strength of workers, power consumption is less, helps energy-conservation, avoided the thermal effect of welding, test component that can damaging stress meter inside.Simultaneously, reinforcement stresses meter uniaxial force under the less situation of bar spacing, still is convenient to operation.The utility model can be applicable to type vibration wire reinforcement stresses meter, is characterized in being easy to installing, and the accuracy height, long-time stability are good, and temperature effect is little, can not produce additive error.Can be used for and being connected of various reinforcing bars.
