Abstract
The utility model discloses a nondestructive test instrument for a concrete structure, which comprises an instrument mainframe, a notebook computer, a preamplifier, a sensor, an excitation system and an electric cable, wherein the notebook computer is provided with detecting software and is connected with the instrument mainframe, and the sensor is connected with the instrument mainframe through the preamplifier. The test range of the nondestructive test instrument is large. The nondestructive test instrument not only can effectively test the mass concrete structure but also can be suitable for testing the standard sample of 15cm. The influence of steel bars is small and can be corrected, the test accuracy is high, and the test range is wide. The nondestructive test instrument can quickly and completely test and evaluate the uniformity, loss and the like of the surface of the concrete structure.
Description
Technical field
The utility model relates to a kind of testing tool, relates in particular to a kind of tester that can the non-destructive testing xoncrete structure.
Background technology
In many engineerings field, all to detect concrete architectural characteristic, traditional detection method is that the concrete at scene is taken a sample, taking back the laboratory then detects,, this way belongs to damaged and detects, and is not suitable for on-the-spot detection, and, then necessarily require on-the-spot Non-Destructive Testing for the detection of the material (intensity, modulus) of concrete structure, defective (crack, peel off, interior void, honeycomb etc.) and physical dimension (thickness, buried depth etc.).
Impact echo commonly used is at present tested concrete instrument, test for large volume high performance for concrete structure thing, be not entirely satisfactory aspect validity and the measuring accuracy, therefore need a kind of xoncrete structure non-destructive testing instrument, measuring accuracy is higher, test specification is wider, can effectively test various volume concrete works.
Summary of the invention
In order to solve above-mentioned problems of the prior art, the purpose of this utility model provides a kind of xoncrete structure non-destructive testing instrument, and measuring accuracy is higher, and test specification is wider, can effectively test various volume concrete works.
The technical scheme that the utility model is taked is: the utility model comprises instrument host, notebook computer, prime amplifier, sensor, excitational equipment; Described excitational equipment carries out exciting to the concrete structure surface, by the signal of sensor record generation; Described number of sensors is many, links to each other with instrument host, and the sensor record signal is amplified by prime amplifier, is conveyed into notebook computer by the parallel port line; Described notebook computer is equipped with detection system, according to internal intensity, elastic modulus, the penetration of fracture, inherent vice, cosmetic bug, thickness, the size of the calculated signals xoncrete structure of importing.
Wherein said excitational equipment comprises ram hammer, peening hammer.
Preferably, number of sensors is 1 or 2.
During use, with excitational equipment shock-testing object gently, the low-frequency elastic ripple that exciting produces is propagated in concrete, imports instrument host into by sensor, tests by the detection software in the notebook computer.Switch by simply soft, hardware, can realize needed method of testing or test event.
The beneficial effects of the utility model are: it is less to decay when elastic wave is propagated in tested object, and hammer vibration energy is adjustable, and the scalable excited frequency, and test specification is big.Not only can effectively test, also applicable to the standard specimen of 15CM at the large volume concrete structural thing; It is little influenced by reinforcing bar, and can revise, and measuring accuracy is higher, test specification is wider, can be fast, full test estimates the homogeneity, loss etc. on concrete structure surface.

Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
As shown in Figure 1, this tester comprises instrument host 1, notebook computer 2, prime amplifier 3, sensor 4, excitational equipment; Excitational equipment comprises ram hammer 5, peening hammer 6, and exciting is carried out on the concrete structure surface, by the signal of sensor 4 record generations; Described sensor 4 quantity are many, link to each other with instrument host 1, and sensor 4 tracer signals are amplified by prime amplifier 3, are conveyed into notebook computer 2 by the parallel port line; Described notebook computer 2 is equipped with detection system, according to internal intensity, elastic modulus, the penetration of fracture, inherent vice, cosmetic bug, thickness, the size of the calculated signals xoncrete structure of importing.
According to the difference of method of testing, sensor 4 can be taked 1 or 2.
During use, with exciting instrument ram hammer 5 or peening hammer 6 shock-testing object gently, the low-frequency elastic ripple that exciting produces is propagated in concrete, import instrument host 1 into by sensor 4, be conveyed into notebook computer through prime amplifier 3 amplifications, test by the detection systems in the notebook computer 2.Switch by simply soft, hardware, can realize needed method of testing or test event.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limit practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the covering scope of the utility model patent.
