Description
Technical field
The utility model relates to a kind of multifunctional concrete strength tester, and this tester is used for the concrete intensity in the engineering construction field is measured, and can test concrete strength with rebound method and two kinds of methods of ultrasonic rebound overall approach.
Background technology
The main method that China tests concrete strength at present has following several: 1, rebound method 2, ultrasonic rebound overall approach.
The at present domestic instrument of testing concrete strength with rebound method mainly is the digital display reisilometer, and the model of reisilometer is also many, but this instrument can only be done the test of rebound value.
Ultrasonic rebound overall approach test concrete strength requires to test the velocity of sound that concrete rebound value and ultrasound wave are propagated at concrete, infer concrete intensity level according to the relation between the two and the concrete strength then, general method is at first to utilize reisilometer to test rebound value at the scene both at home and abroad at present, test acoustic velocity value at the scene with Ultrasound Instrument then, after data test finished, need with computing machine with the data transmission in two kinds of instruments in computing machine, just can obtain concrete intensity after calculating with special-purpose software analysis then.The process of this test has following shortcoming:
1, instrument price comparison costliness, the cost height.The price of an at present domestic Ultrasound Instrument is all about 4～50,000 yuan, the price of a reisilometer is about 10,000 yuan, if like this with ultrasonic rebound overall approach test concrete strength, the total price of instrument is about 60,000 yuan, the cost height of the unit of detection not only, this also is to cause the charge of ultrasonic rebound overall approach test concrete strength than a higher main cause.
2, execute-in-place complexity.When testing at the scene, at first to test rebound value with reisilometer, to test the acoustic velocity value of ultrasonic propagation in the concrete then with Ultrasound Instrument, the hardware platform of Ultrasound Instrument is based on the PC104 mainboard of X86 system, it is equivalent to a small-sized computing machine, than higher, the execute-in-place complexity is than higher, and test speed is slow for the requested knowledge of operator's peopleware and relevant industry.
3, two instrument is integrated difficulty.The hardware platform of reisilometer is the single-chip microcomputer platform, and the hardware platform of Ultrasound Instrument is based on the PC104 mainboard of X86 system, realizes that on platform each other two functions all exist a lot of problems, does not therefore have this comprehensive instrument so far and appears on the market.
4, the data analysis result inconvenience in later stage.Because when testing at the scene, data are to be kept at two independently in the instrument, and this handles after requiring the user only with PC the data transmission in two instruments to be come out, and can not carry out on-the-spot analyzing and processing.
5, poor compatibility.The data layout of the domestic reisilometer of each producer at present is all different, the data layout of Ultrasound Instrument is also different, the analysis software of producer and producer mutually can not compatible data, the result who causes is that reisilometer and Ultrasound Instrument can only be bought could analyzing with software of same producer, otherwise the user then can only wait own computational analysis test result with Excel or counter.
6, portable poor.Because test need be used two kinds of instruments, Ultrasound Instrument main frame and accessory weight together reach about 5 kilograms, reisilometer together with the weight of accessory also about 2 kilograms, so that the user carries in the reality test is very inconvenient.
The utility model content
