Description
Technical field
The utility model is related to a kind of built-in type vibration measurement probe, belongs to construction industry, prefabricated concrete structure, engineering
Technical field of quality detection.
Background technology
At present, straight screw sleeve connection is the bar connecting mode commonly used in prefabricated concrete structure, and sleeve grouting is full
Degree is the important node of fabricated construction quality control on construction.
《JGJ 355-2015 reinforced bar sleeves grouting connection application technology code》In the 7.0.10 articles regulation " grouting should be closely knit
Full, all grout outlets all should pulp ".
The metering system used at present is measured in plasma discharge hole insertion sensor, and this metering system has measurement
Position it is inaccurate and easily by construction infection and interference the problems such as.
In the production of actual prefabricated components, grout sleeve exports to component surface by grout pipe, grout outlet, is follow-up fill
Slurry construction reserved grout hole, plasma discharge hole；Because the structure of component in itself needs, some grout outlets need bending to circumvent some specific knots
Structure gets to component surface, along with the disturbance in construction, it is impossible to which control grout outlet completely is vertical with component surface.
In grouting construction, it may appear that grout sleeve blocks the phenomenon for being unable to pulp, it is necessary to which operating personnel enter to slurry outlet
Row dredging, if now slurry outlet is disposed with probe, operating personnel, which extract, to pop one's head in, after cleaning again insertable into operation have it is larger
Probability causes damage to probe.
Utility model content
The purpose of this utility model is to provide a kind of built-in type vibration measurement that can overcome above-mentioned technical problem to pop one's head in,
The utility model be it is a kind of can be arranged on grout sleeve on anchorage length of steel bar design load position probe, the utility model energy
Whether anchorage length of steel bar reaches design requirement after enough accurate measurement grouting constructions.
A kind of built-in type vibration measurement probe of the present utility model is made up of shell, vibrating sensor, casting glue and wire.
The vibrating sensor uses Multi-contact with shell, can effectively reduce contact area, at utmost reduces and vibration is passed
The influence of sensor centre of oscillation frequency.The vibrating sensor is potted in housings using casting glue, the wire with it is described
Vibrating sensor is connected；The flexible modulus of casting glue.
The utility model has the advantages that：Grout sleeve cooperation of the utility model with that can install measurement function additional can be in component
The utility model is arranged in control height exactly before production；In the utility model with the grout sleeve of measurement function can be installed additional
It after the component grouting formed after cooperation, can accurately measure whether control height is full of grouting material, i.e., can accurately measure
The grouting plumpness of the component.Therefore, the utility model has notable practical value.

Embodiment
Embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.As shown in Figure 1 and Figure 2, this practicality is new
A kind of built-in type vibration measurement probe of type is made up of shell 1, vibrating sensor 2, casting glue 3 and wire 4.The vibrating sensing
Device 2 uses Multi-contact with shell 1, can effectively reduce contact area, farthest reduces to the vibrating sensor 2
The influence of centre of oscillation frequency.The vibrating sensor 2 is potted in the inside of shell 1 using casting glue 3, the wire 4 with it is described
Vibrating sensor 2 is connected；The flexible modulus of the casting glue 3.
As shown in Figure 3, Figure 4,5 be grout sleeve；6 be built-in type vibration measurement probe, and L0 designs for anchorage length of steel bar
Value, R0 is the radius that built-in type vibration measurement is popped one's head in.Pacify in the grout sleeve sensor mounting hole position that can install measurement function additional
The built-in type vibration measurement probe 6 is filled, it is long that 6 setting height(from bottom)s of the built-in type vibration measurement probe are more than or equal to Bar Anchorage
Spend design load L0 and built-in type vibration measurement probe 6 radius R0 sums.
This grout sleeve 5 for being mounted with the built-in type vibration measurement probe 6 as shown in Figure 3, Figure 4 can be in grouting
Accurately judge whether anchorage length of steel bar design load L0 position is filled by measuring the signal of the vibrating sensor 2 after construction
Full irrigation slurry, i.e., can accurately judge the grouting plumpness of grout sleeve 5.
Vibrating sensor 2 described in the utility model can produce the vibration of certain frequency under the driving of specific incentives signal.
Any mechanical oscillation can use below equation：
To represent, wherein X is amplitude, A0It is that time, ω are that the natural angular frequency of vibrational system, β are for initial amplitude, t
Damped coefficient, e is science constant,For initial angle.The amplitude wherein vibrated is exponentially decayed, when vibrating body is certain, excitation after
The amplitude and frequency of initial vibration are certain, and its bigger damped coefficient of elastic modelling quantity of the medium around vibrating body is bigger, therefore
Medium around vibrating body is the mortar after empty gas and water, the mortar of flowing, solidification, and its damped coefficient increases successively, accordingly,
The decay of amplitude will be sharply increased.Design to encourage by electric signal for this and produce the resistance vibrated and can received after excitation revocation
The vibrating sensor of Buddhist nun's vibration signal and corresponding detecting instrument, can install pre- be mounted in of built-in type vibration measurement probe additional measurement work(
Mounting hole site on the grout sleeve of energy, makes the centre-height of built-in type vibration measurement probe 6 be more than or equal to anchorage length of steel bar
Design load L0 and built-in type vibration measurement 6 radius sums of probe, the i.e. lower edge of built-in type vibration measurement probe 6 are more than or equal to steel
Muscle anchorage length design load L0, then can by receiving the attenuation of signal amplitude come the character of discriminating sensor surrounding medium,
To reach the purpose of the detection grouting plumpness of grout sleeve 5.
The above, embodiment only of the present utility model, but protection domain of the present utility model do not limit to
In this, any one skilled in the art is in the utility model scope of disclosure, the change that can be readily occurred in
Or replace, it should all cover in the utility model scope of the claims.
