Specific embodiment
The embodiments of the present invention are described in detail below in conjunction with attached drawing, but the utility model can be by right
It is required that the multitude of different ways for limiting and covering is implemented.
Embodiment:
The technical solution of the utility model is schematically illustrated below by Fig. 1 and Fig. 2, according to the utility model reality
That applies mode is designed to provide a kind of intelligent anchor bolt, and it further includes gasket which, which includes anchor bolt seat 10, screw rod 11 and nut 13,
12, the gasket 12 is set on the screw rod, between the anchor bolt seat 10 and the nut 13, in the gasket 12
First party sets up the first deformation acquisition device 121, and the first deformation acquisition device exists the collected gasket 12
First direction occurs the first deformation signal and is sent to suggestion device 30, and the suggestion device 30 is sent out according to first deformation signal
Prompt information out.
The anchor bolt seat 10 of anchor bolt can be set according to requirement of engineering according to factors such as the substrate hardness of anchoring in the present embodiment
Different shape, the anchor bolt seat 11 as shown in the present embodiment Fig. 1 select taper, other shapes also can be set into, as long as anchor bolt seat
11 outer diameter is greater than 11 outer diameter of screw rod, can play the role of anchoring.Gasket 12 in the present embodiment compares in axial length
Greatly, deformation acquisition device is wanted to be arranged in gasket 12.As shown in figure 3, the intelligent anchor bolt of the present embodiment is to be anchored on coagulation
Illustrate working principle for steel plate 4 is fixed in soil matrix bottom 5.Anchor bolt seat 11 is deep into cast concrete base 5, specifically may be used
To be embedded in advance in concreting, the anchor bolt seat 10 and half of screw 11 of anchor bolt are secured to coagulation after the concrete has set
In soil matrix bottom 5, another part screw rod of anchor bolt passes through the hole for being fixed steel plate 4 and gasket 12 is fastened by nut 13, pads at this time
Piece 12 is tightly attached on steel plate 4 by nut 13 and generates pretightning force, and usual situation is fixed a steel plate 4 by several anchor bolts or led to
Several anchor bolts are crossed a fixed point of steel plate 4 is fixed.If loosening or tension occur for one of anchor bolt, gasket
Deformation occurs for 12 meetings, and deformation acquisition device 121 can collect the deformation of gasket 12 and the deformation is sent to suggestion device
30, suggestion device 30 issues prompt information.
In order to which whether the monitoring anchor bolt of more reliable property the abnormal conditions such as occurs loosening, in the second direction of the gasket 12
Second deformation acquisition device 122 is set, and second deformation acquires 122 devices for the collected gasket 12 in second direction
The second deformation signal occurs and is sent to suggestion device 30, the suggestion device 30 is according to first deformation signal and the second deformation
Signal issues prompt information.Wherein first direction is vertical with the second direction.Such as first direction is the axial direction of gasket 12, the
Two directions are the radial direction of gasket 12.The first deformation acquisition device 121 and the second deformation acquisition device 122 in the present embodiment
Strain ga(u)ge can be selected, due to electronics strain gauge structure it is simple it is small in size can be convenient be mounted in gasket 12.Gasket
12 are easy to generate deformation, such as when the pressure between gasket 12 and steel plate 4 becomes larger, 12 thickness value of gasket can become smaller namely axis
To deformation occurs, horizontal direction diameter will increase namely it is radial deformation occurs, deformation occurs produces for corresponding two strain ga(u)ges
Raw first deformation signal and the second deformation signal.
The structure of gasket 12 is specifically described as shown in Figure 2, which is provided with first in a first direction namely axially
Accommodating chamber, for accommodating electronics strain gauge 121；It has been arranged radially the second accommodating chamber in second direction namely gasket 12, has been used for
Accommodate electronics strain gauge 122.After gasket 12 squeezes, sagittal plane sinks toward center, and deformation occurs, and the bigger deformation quantity of stress is more
Greatly.When gasket 12 is by pressure, its radial deformation, which is greater than axial deformation amount, can be used as quantitative test, and axial test can be used for
Qualitative test.Comprehensive both direction test data, can make reliable test result Du Genggao.
The intelligent anchor bolt of this programme is fixed in concrete in addition to that can pour, can also in the concrete solidified or
Fixed on person's rock, anchor bolt seat 10 and half of screw 11 protrude into the preformed hole of concrete or rock at this time, use adhesive
Anchor bolt seat, half of screw 11 are closely bonded with concrete, so that anchor bolt, adhesive and concrete combine together.In order to enable
Anchor bolt is more firm to combine together with concrete, adds base expanding and base expanding blade 14 on the screw rod 11, and the base expanding and base expanding blade 14 is described
Intelligent anchor bolt slides into 10 periphery of anchor bolt seat when being anchored in the substrate.It is more reliable to increase the outer diameter of anchor bolt seat 10
Anchor bolt is anchored on concrete or by rock.When anchor bolt after the installation is completed, base expanding and base expanding blade is mobile to 10 end of anchor bolt seat, anchor bolt
The pyramidal structure of seat 10 makes base expanding and base expanding blade 14 expand and be formed the blade of cone expansion.Base expanding and base expanding blade 14 and anchor bolt seat 10 are embedded in
Into concrete, when anchor bolt bears pulling force, knife tooth (boss on base expanding and base expanding blade) and concrete generate frictional force, this power can
It is decomposed into horizontal friction force and axial frictional force.Wherein axial frictional force generates concrete to its outer surface
Pressure so concrete will not be destroyed, anchor bolt namely will not be loosened since concrete is able to bear higher pressure.
Installation suggestion device 30 for convenience is provided with the fixation for fixing suggestion device 30 in the periphery of gasket 12
Frame 20.The fixed frame 20 is arranged to semiclosed shape, such as is arranged to U-shaped structure as shown in Figure 1, and wherein the opening of U-shaped is fixed
On gasket 12, it is fixed etc. that fixed form can be welding or bolt, such as Fig. 2 example, is provided with bolt hole, U on gasket 12
The fixed bracket 20 of shape is bolted on gasket 12, is used in the enclosure portion namely U-shaped bottom position of U-shaped structure solid
Determine suggestion device 30, which also can choose is integrally formed with gasket 12.
The state of anchor bolt can be monitored in real time in the present embodiment intelligence anchor bolt, describe intelligent anchor bolt from electric part below
Monitoring framework, as shown in figure 4, the intelligent anchor bolt monitoring system of the utility model includes power supply 308, amplifying circuit 303, modulus turns
