Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
- 3 are please referred to Fig.1, the utility model provides a kind of technical solution：A kind of fabricated shear wall seat pulp layer defects detection
Device, including computer 1, hand hammer 4 and substructure 7, the port of computer 1 are fixedly connected with signal amplifier by data line
2, the input terminal of signal amplifier 2 is fixedly connected with sensor 3 by data line, and the top of substructure 7 is fixedly connected with seat
Pulp layer 6, the top for sitting pulp layer 6 are fixedly connected with preformed hole wall 5, are 3cm at a distance from hand hammer 4, sensor 3 and seat pulp layer 6, small
Hammer 4 is 3cm-5cm at a distance from sensor 3, and the side of sensor 3 is contacted with the surface of preformed hole wall 5, hand hammer 4 and sensing
For device 3 in same level, hand hammer 4 uses rubber hammer, detection to include the following steps：
S1：Seat pulp layer is poured between prefabricated components, after maintenance molding；
S2：Computer, signal amplifier, sensor are connected, host parameter is set；
S3：Sensor is attached on the surface of detected preformed hole wall；
S4：The surface for being detected preformed hole wall is tapped with hand hammer；
S5：Sensor receives reflection signal；
S6：Signal amplifier is amplified the signal received and signal data is stored in instrument；
S7：Computer reads signal data and goes forward side by side traveling wave spectrum analysis, and analysis result and control group are compared, obtain this
Sit the compaction rate of pulp layer.
After seat pulp layer grouting construction between prefabricated components, ensure that slurry condensation hardening strength is at least up to design strength
75%.It is practiced by above-mentioned steps, you can judge to sit the closely knit feelings being in the milk inside pulp layer by reflecting the characteristic of signal
Condition, according in the size for sitting the frequency values in pulp layer, you can the defect situation being in the milk inside pulp layer is sat in judgement.
As shown in Figure 2 and Figure 3, it is that the utility model is sitting two kinds of whether closely knit testing result schematic diagrames of pulp layer.
Fig. 2 is the typical testing result schematic diagram sat under pulp layer dense state, and Fig. 3 is the typical detection knot sat under the defective state of pulp layer
Fruit schematic diagram.It measures to obtain and sits pulp layer top shear wall signal, acquisition signal obtains peak value through Fast Fourier Transform (FFT) (FFT)
Frequency f1, the position at pulp layer 3cm is sat with same method impact distance, crest frequency f is obtained after handling signal2.If f1It is less than
f2, and f1≈0.86f2, then immediately below the hand hammer and sensor region seat pulp layer existing defects；If f1≈f2, illustrate that the seat is starched
Layer is closely knit.The directions A in diagram 1 are tapped, and test successively sits pulp layer and differentiates closely knit situation, obtains and entirely sits pulp layer
Defective locations.When sitting pulp layer existing defects, shear wall bottom is caused to form free boundary, when shock point is close to the boundary of component
When, the echo vertical component on boundary can influence the echoing characteristics of the component other side so that frequency is approximately to low frequency wonder, frequency values
Non-boundary influences 0.86 times of frequency values, and the compactness feelings of seat pulp layer are judged by the size for the waveform frequency reduction amount surveyed
Condition illustrates that utility model device and test method may determine that and sits pulp layer compactness situation
