Whether disconnected intelligence anchor bolt working condition is normal.
The course of work of strain ga(u)ge is described in detail by attached drawing 6 and attached drawing 7 as follows.
Strain ga(u)ge 121 is a kind of current sensing element, it is made of substrate, sensitive grid, coating and electrode.Substrate
Positioned at lower layer, middle layer is sensitive grid, and upper layer is coating, and electrode is located at device one end.Base material is phenolic aldehyde, and sensitive grid is
Alloy.When strain ga(u)ge 121 is attached to testee, measured object dignity changes with stress and generates deformation, strain ga(u)ge
Deformation occurs together with sensitive grid for 121 substrates, is eventually exhibited as resistance value and changes.
Calculate that stress value is demarcated by resistance-strain deformation.Calibration principle is with process as shown in fig. 6, resistance is answered
Become meter RX to connect with fixed value resistance R1, apply voltage value U0 to series circuit, then two resistance intermediate voltage values are U1, U1=
U0* [R1/ (RX+R1)].Voltage U1 is faint analog signal, and amplified voltage is N*U1, then is become through analog to digital conversion circuit
For digital voltage value M.
Tool is generated using proof force and applies known pressure F to gasket 12, through the above process, signal processing circuit microcontroller
It is digital voltage value M that device 305, which calculates result,.Since resistance value and stress value are linear change, two number of general measure
Value can establish stress F and digital voltage value M relationship, as shown in fig. 7, first is the corresponding digital voltage of maximal force F1
Value M1, then measure the corresponding digital voltage value M2 of a minimum value F2.One stress F and digital voltage value can be described by two o'clock
Relationship straight line between M.After stress straight line is established, stress F is finished with the foundation of digital voltage value M relationship, signal processing electricity
Road can calculate absolute stress value F according to digital voltage value M.
It is to be noted that axial change with radial measurements is opposite when power increases or reduces.Gasket 12 is born
121 length of axial direction strain ga(u)ge shortens when pressure increases, and resistance value RX becomes smaller, by formula U1=U0* [R1/ (RX+R1)]
Know that U1 value increases, is eventually exhibited as M increase.Gasket 12 bears to collapse facing radially towards center when pressure and show as expanding, radial
Strain ga(u)ge Tensile, resistance value RX become larger, and know that U1 value becomes smaller by formula U1=U0* [R1/ (RX+R1)], final to show
For M reduction.It is axial equal it can be inferred that stress changes with radial variations by detection when anchor bolt stress changes greatly.
When microcontroller 305 judges that the practical pressure born of the sensor is greater than the anchor bolt and pre-tightens force threshold maximum
Value, microcontroller 305 issue overload prompt to prompt unit 300；It is born when microcontroller 305 judges that the sensor is practical
Pressure thinks that pretightning force is reduced when pre-tightening force threshold minimum value lower than the anchor bolt, the microcontroller is to the prompt unit
300 issue loosening prompt.
In order to effectively prompt engineering staff to understand the state of anchor bolt in real time, the suggestion device 30 in the present embodiment includes existing
Field prompt unit 302 and remote terminal prompt unit, it is possible thereby to realize the far and near monitoring of anchor bolt axial pre tightening force, greatly
It ensure that the convenience of safety and control processing.Live prompt unit 302 preferably sounding device and/or light emitting device (under
Also with 302 calibration sounding devices and light emitting device in text), in this way when live prompt unit 302 receives overload or loosens pre-
Different sound and/or different light can be issued when alert signal.Typical sounding device can select buzzer 302, micro-
Controller 305 can be according to overload or loosening control buzzer 302 issues different sound, and light emitting device can be sending not
The luminescent device 302 of same color, different color of light is issued when receiving different standby signals, is issued when such as overload prompts
Feux rouges issues blue light when loosening prompt.And the remote terminal host of remote terminal prompt unit, it can be computer, mobile phone,
IPAD, the terminal devices such as Intelligent bracelet, controllers can carry out control operation according to prompt on end host, avoid overhauling
Personnel carry out site examining and repairing, very convenient.
Specifically, referring to attached an example practical application shown in Fig. 3.As shown in figure 3, the intelligent anchor bolt of the present embodiment usually with
Anchored mode, which will need to be fixed on the steel plate in cast concrete base 54, to be implemented to fix, and anchor bolt seat 11 is deep into cast concrete base 5,
It can be specifically embedded in advance in concreting, the anchor bolt seat 10 and half of screw 11 of anchor bolt are just solid after the concrete has set
It is scheduled in cast concrete base 5, it is tight by nut 13 that another part screw rod of anchor bolt passes through the hole for being fixed steel plate 4 and gasket 12
Gu gasket 12 is tightly attached on steel plate 4 by nut 13 and generates pretightning force at this time, usual situation fixes one by several anchor bolts
Steel plate 4 is fixed by a fixed point of several anchor bolts to steel plate 4.If loosening or mistake occur for one of anchor bolt
When tight, gasket 12 can deformation occurs, and strain gauge 121 can collect the deformation of gasket 12 and the deformation is sent to control
Judging result is sent to live prompt unit 302 and remote terminal prompt unit again by unit 200 processed, control unit 200, is issued
Prompt information.Specific judgement and prompting mode are repeated no more referring to above description.
It further illustrates, for the steel plate 4 fixed using intelligent anchor bolt, if necessary to multiple intelligent anchor bolts, it is not necessary to
Whole anchor bolts is all used into intelligent anchor bolt.It can be one, two or 3.Certainly not be cost consideration, 4 be also can
With.
In this way, intelligence anchor bolt according to the present invention, can not only monitor the pretightning force of anchor bolt in real time and can issue and mention
Show information, engineering staff can the convenient and efficient and anchor bolt that efficiently notes abnormalities, carry out checking that excluding hidden danger avoids occurring in time
