Description
Technical field
The utility model is related to assembled architecture fields, and in particular to a kind of slurry anchor connection part with detection hole.
Background technology
Prefabricated assembled concrete structure has speed of application as a kind of structure type meeting industrialized production
Soon, labor intensity is low, noise pollution and wet construction is few and the advantages such as product quality is easy to control, it has also become domestic and international construction industry development
Main flow direction.2 months 2016《State Council of the Central Committee of the Communist Party of China is about several meanings for further strengthening urban planning and development control work
See》It proposes, strives with 10 years or so time, making assembled architecture account for new building ratio and reaching 30%, assembled architecture is at me
The development of state is being thus lifted to a unprecedented height.
In assembled arthitecutral structure, especially in prefabricated concrete structure, component connection is to ensure that structure is whole
The key node of quality.It is the common bar connecting form in prefabricated concrete structure that reinforcing bar, which starches anchor overlap joint connection, starches anchor
It overlaps and is connected as concealed work, the plumpness of strength cement-based grouting material directly influences prefabricated concrete structure in slurry anchor connection part
Quality and safety.But may be because personnel's lack of skill, misoperation in work progress or lack a sense of responsibility, cause
Spillage, running pulp phenomenon happen occasionally, and the appearance of this phenomenon has seriously affected grouting quality, the case where " filling discontented " occur, make
At fatal constructional deficiency.Therefore, in slurry anchor connection part the detection method of strength cement-based grouting material plumpness and find be in the milk
Benefit paste-making method when insufficient is building trade extensive concern and urgent problem to be solved.
The detection method of the plumpness of slurry anchor connection part grouting at present is broadly divided into member exterior nondestructive determination and inside is pre-
The method for burying sensor.
Member exterior lossless detection method is mainly supercritical ultrasonics technology, Impact echo and x-ray method.Due to slurry anchor connection knot
Structure replaces for multilayer dielectricity, and detection environment is complicated, and strength cement-based grouting material is relatively thin in radial thickness, the generally ㎜ of 10 ㎜~14,
Although supercritical ultrasonics technology and Impact echo can be found that the uncompacted situation of grouting to a certain extent, to grout compartment and non-filling
The interface of slurry section judges not accurate enough, can't be applied to engineering practice at present.X-ray method can more clearly judge single row of holes
The interface of grout compartment and non-grout compartment inside road, but specimen thickness when its effective detection has apparent limitation.
It is more mature at present in internal pre-buried sensor method to be detected for pre-buried sensor DAMPED VIBRATION METHOD, in grouting operation
The preceding bottom that damping vibration sensor is embedded in slurry outlet, in filling process and grouting material initial set advance row amplitude and energy
It is worth real-time testing, judges whether sensor is coated by grouting material by checking the amplitude decay situation of sensor signal, with true
Whether fixed grouting is full closely knit.But this method has the shortcomings that following three：(1) can only qualitative detection, can not be to grouting material
Turgor carries out quantitative analysis, and difficulty is brought for the result judgement in later stage；(2) damping vibration sensor must be in grouting construction
Before be installed in place, sensor once be embedded to cannot reuse, if in engineering all slurry anchor connection parts all arrange
Sensor, later stage are taken a sample test at random, then testing cost is excessively high, each side is difficult to receive, if the random cloth before grouting construction
A limited number of sensors are set, construction party learns test point in advance according to sensing station, will be directed to known test point essence
The heart is constructed, and finally loses the meaning inspected by random samples at random, and still buried security risk.(3) in progress when plastering construction, also
It obtains and cuts off the sensor for stretching out wall part, it is time-consuming and laborious to ensure the planarization of wall.
In addition, when both the above detection method carries out late detection after grouting material solidification, even if finding slurry anchor connection part
Grouting is not filled, can not also be carried out in-situ repair, can only be replaced entire prefabricated components or underproof slurry anchor connection part is picked chisel
Out reinforcement welding is used to connect, is then repaired with new concrete or strength cement-based grouting material to picking the concrete chiseled out.
This method for repairing and mending can not only result in waste of resources, and can also influence the progress of next process, cause construction delay.
Publication No. is that the Chinese patent literature of CN106836657A, CN105865568A propose a kind of bar connecting filling
Repair apparatus and method of the sleeve (or device) when being in the milk insufficient, and the non-destructive ration examining device of grouting defect are starched,
Essence be simply increased on grout sleeve (or slurry anchor connection part) patching material input pipe, patching material output channel,
Detect liquid input tube road, detection liquid output pipe road amounts to four newly-increased pipelines, when Site Detection, then utilizes input liquid bulk
Product metrical instrument, output liquid volume measuring instrument and water supply installation, will input the volume of liquid and the volume of output liquid are done
Difference obtains the liquid volume being trapped in grout sleeve, to judge grouting material plumpness situation, if grouting is not full, uses
Grouter injects patching material into grout sleeve (or slurry anchor connection part) by patching material input channel, and will be left in grouting
Detection liquid displacement in sleeve (or slurry anchor connection part) comes out, and the outlet in the patching material output channel is needed to be divided
Period samples, until patching material output channel stablizes the density of the patching material of discharge and the injection repairing material into grout sleeve
The density of material quite or when reaching setting density stops repairing.Above-mentioned apparatus and method seem simple possible, there are in fact with
Lower disadvantage and the erroneous judgement that testing result can be caused：(1) itself to grout sleeve (or slurry anchor connection part), on slurry outlet
For tetra- holes of Fang Zengshe for plugging four pipelines, the number of openings is excessively likely to result in grout sleeve (or slurry anchor connection part)
The decline of mechanical property, brings major safety risks.(2) for the prefabricated components manufacturing, sleeve (or slurry anchor connection part)
On the various pipes added it is excessive, in addition original grout lines and pulp pipeline will have six roots of sensation pipeline simultaneously centralized arrangement pre-
Sleeve (or slurry anchor connection part) position in component processed, if it is double sleeve (or double slurry anchor connection part), then number of tubes is also
Will be double, this, which will undoubtedly vibrate to concreting, brings very big inconvenience, to influence production efficiency and component quality.(3)
Field detecting device is complicated, and the equipment such as input liquid volume metrical instrument, output liquid volume measuring instrument and water supply installation are existing
Field assembly and adjustment is cumbersome and inconvenient to carry.(4) it is practical to be not associated with engineering for quantitative detecting method, testing result there may be
Large error be easy to cause erroneous judgement；The above method by be trapped in the liquid volume in grout sleeve (or slurry anchor connection part) come
Judge that the turgor of grouting, this partially liq have not crossed slurry outlet and full of the cavity areas in sleeve (or slurry anchor connection part)
And the cavity area in pulp pipeline, since grouting material viscosity is larger, after the completion of grouting, grout outlet blocks tightly, even if sleeve
Stream of slurry in (or slurry anchor connection part) is empty, in the pulp pipeline of horizontal direction still can there are grouting materials, but in pulp pipeline
The final form of grouting material can not determine that the volume of i.e. cavity area in pulp pipeline is unknown, and the above method is directly used
The liquid volume in grout sleeve (or slurry anchor connection part) is trapped in measure the not turgor of grouting, does not consider pulp pipeline
The volume metering error that interior remaining grouting material is brought, it is easy to cause to judge by accident.(5) it is not that detection liquid is taken out in selection when mending slurry
Benefit slurry is carried out after going out again, but is gone out by patching material by liquid displacement is detected；The above-mentioned repair apparatus of onsite application and method
When, the density that patching material output channel stablizes discharge patching material can not be detected fast and accurately, and the lasting benefit slurry of blindness holds
The waste of grouting material is easily caused, cost is increased.

With reference to shown in Fig. 6, in order to avoid the appearance of the not full problem of above-mentioned grouting, a kind of slurry anchor company with detection hole is provided
The detection method of fitting grouting plumpness, including above-mentioned slurry anchor connection part, industrial endoscope, syringe, water filling hose and rubber
Leather plug；
In grouting, first have to ensure that detection hole can not be blocked by slurry, rubber stopper is in prefabricated components manufacturing process
It is arranged in the sense channel of slurry anchor connection part, and positioned at close to one end of detection hole；Therefore when slurry is in perfusion, pulp
Negative pressure space can be formed in bellows above hole, slurry will not pour in detection hole, and the unimpeded of sense channel has been effectively ensured.
Industrial endoscope includes probe pipeline, and probe pipeline both ends are separately connected endoscope host and endoscope probe；
The dispensing end of water filling hose and syringe connects；
Terminate and be detected after curing specifically, this method is the slurry anchor connection part grouting being preset in prefabricated components,
Steps are as follows for its detection method：
The rubber stopper in detection hole is taken out first；Then the endoscope probe of industrial endoscope is stretched from sense channel
Enter, passes through the control to endoscope probe, the bellows interior grouting situation of observation endoscope probe shooting, the picture energy of shooting
Enough as the image observed in real time, the foundation that subsequent detection unit carries out result evaluation is can be used as, photo is attached to detection
In report, increase the intuitive and authenticity of examining report；When bellows interior slurry face height is more than or equal to slurry outlet
When the height of bottom, as full grouting, grouting plumpness is determined as qualification；When slurry face height is less than the height of slurry outlet bottom
When spending, as insatiable hunger full irrigation is starched, and need to be continued grouting plumpness and quantitatively be detected；
Wherein, the bellows interior reinforcement location that can also be shot using endoscope probe, when the second prefabricated components are vertical
When the end that reinforcing bar stretches into bellows is not coated by grouting material completely, you can to observe reinforcing bar, whether judge reinforcing bar with this
It requires according to the rules in the insertion connector of foot length.
It is judged as that insatiable hunger full irrigation is starched after above-mentioned detection, and grouting plumpness need to be carried out when quantitatively detecting, first passes through syringe
Detection liquid is extracted, then water filling hose is connected on the dispensing end of syringe, and press syringe, makes the liquid in syringe
Body enters in water filling hose, when water filling hose end is discharged, stops pressing, this operation can avoid vacant in water filling hose lead
The generation of water filling error is caused, accuracy of detection is improved；By initial capacity in calibration record syringe, then by water filling hose from inspection
It surveys channel to stretch into bellows, presses syringe again, make in liquid injection bellows, liquid height is checked by industrial endoscope
Degree avoids the uncertainty that pulp pipeline inner cavity body accumulates from bringing measurement error, with reference to shown in Fig. 4 and Fig. 5, when liquid reaches out
When starching the height of hole bottom, stop pressing, and by capacity after being injected in calibration record syringe, hold after initial capacity and injection
The difference of amount is the water injection rate of syringe, as filling defect capacity, and standard grout amount and the filling defect of slurry anchor connection part hold
The difference of amount is practical grouting quantity, and the ratio between practical grouting quantity and the standard grout amount of slurry anchor connection part are that practical grouting is full
Degree, which is easy to operate, high certainty of measurement, and carries and use convenient for building-site, and testing cost is extremely low；
In order to be more accurate obtain detection data, before calculating and being in the milk plumpness, the quasi- grouting quantity calibration of advanced rower takes
One section of bellows sample, the length of bellows sample is more than the height of grout outlet bottom in slurry anchor connection part, to bellows sample
Sealed bottom simultaneously places bellows sample vertically, then to bellows sample interior water filling, when reaching in slurry anchor connection part
When starching the corresponding height in hole bottom, bellows sample interior water is measured, bellows sample capacity is obtained, by bellows sample
Capacity subtracts the second prefabricated components vertical reinforcement and stretches into bellows and positioned at grout outlet bottom level with the volume of lower part, i.e.,
Obtain standard grout amount；
Wherein, bellows sample is consistent with the bellows model used in slurry anchor connection part, to ensure the accuracy compared.
Measurement can be compared with grouting plumpness Con trolling index, if practical grouting is full after obtaining practical grouting plumpness
Degree is more than or equal to grouting plumpness Con trolling index, then is still determined as qualification, if practical grouting plumpness is less than grouting plumpness control
Index processed, then be determined as it is unqualified, compared by the calculating of plumpness can avoid erroneous judgement situation appearance, increase examining report
Public trust with it is authoritative；
Live randomness detection may be implemented in above-mentioned detection method, need to only take out the rubber stopper in sense channel
It is detected, without arranging measuring point in advance before grouting construction, virtually increases random checking dynamics, there is no because of thing
The problem of first arranging measuring point and construction party caused to ignore grouting quality except measuring point (grouting quality except measuring point can not detect),
Advantageously ensure that quality and the safety of reinforcing bar slurry anchor overlap joint connection.
And in order to ensure the durability subsequently used, water filling hose is stretched into the liquid in bellows, then pull
Syringe extracts liquid out, restores defect cavity, completes detection, avoids the liquid holdup of injection to bellows and and stretches
The the second prefabricated components vertical reinforcement entered in bellows causes quality to influence；
It is above-mentioned when to bellows water filling, measurer may be used to bellows sample interior water filling, obtained by gage dial
It is convenient and efficient to bellows sample capacity.
It when above-mentioned detection method is determined as unqualified, can carry out studying for a second time courses one has flunked operation, be starched in the benefit of the utility model
In one embodiment of method, benefit slurry is carried out using following steps：It is drilled first to pulp channel using drilling device, on one side
Drilling clears up grouting material disintegrating slag in duct on one side until ripple tube cavity will be detected using slurry outlet as the slurry-feeding hole mended when starching
Hole is as the gas vent (slurry outlet) mended when starching, you can carries out in-situ repair, then carries out supplementary irrigation slurry from pulp channel, work as slurry
It completes to mend slurry work when being discharged from sense channel.Liquid extraction will be detected by syringe and water filling hose before repairing,
It only needs just to can reach connection request after directly filling up the gap that do not fill, saves grouting material.
Certainly this mends paste-making method and can also be used before not detecting plumpness, when construction party voluntarily judges not conforming to very likely
It when lattice, is directly studied for a second time courses one has flunked using above-mentioned benefit paste-making method, to achieve the effect that high quality is built.
And due to the design structure of this slurry anchor connection part, when the slurry anchor connection part grouting being preset in prefabricated components terminates
And it after curing, is drilled first to pulp channel using drilling device, cured slurry is smashed and cleared up, pulp channel is made
Then perforation carries out supplementary irrigation slurry from pulp channel, the sense channel of the slurry anchor connection part is located at top, therefore works as slurry from detection
It completes to mend slurry work when channel is discharged, above-mentioned design effectively simplifies repairing step, simple operations, and repairing quality greatly improves.
In another embodiment, the utility model or unit in charge of construction or supervisor also workable method, when default
Slurry anchor connection part grouting in prefabricated components terminates and before initial set, the rubber stopper of sense channel is taken out, then will be in industry
