Description
Technical field
The present invention relates to assembled arthitecutral structure, the tandem sleeve grouting inspection of specifically a kind of vertical prefabricated components
Geodesic structure, and the tandem sleeve grouting detection method based on the structure.
Background technology
Precast reinforced concrete structure has had more practical application and more in developed countries such as America and Europe, Japan
Ripe technical research.Compared with traditional cast-in-place concrete, the craft at the precast reinforced concrete structure scene of can reducing
Labour and wet construction, construction speed is fast, small to surrounding environment influence, and the quality of prefabricated components is easy to control, and the entirety of project is applied
Working medium amount is easier to ensure.
The research that prefabricated assembled concrete is built with China with widely popularize, prefabricated concrete structure is in China
Significant progress is obtained.
The connection of prefabricated components is to influence one of the key technique of structure safety in prefabricated concrete structure.Prefabricated structure
The connection of part includes mainly the connection of the connection and concrete of reinforcing bar, and the quality of connecting portion will directly influence the peace of structure
Entirely.
In traditional cast-in-place concrete structure, the connection generally use mechanical connection, welding between reinforcing bar or binding overlap joint,
And in fabricated construction, the connection type of reinforcing bar is in addition to above-mentioned several, also sleeve grouting connection, slurry anchor overlap joint connection etc.,
And bar diameter it is larger when should not use slurry anchor overlap joint.From the force request of connecting portion and facilitates site operation this two is pointed out
It sends out, in assembled arthitecutral structure, the connection between vertical prefabricated components Reinforcement has mostly used sleeve grouting and connected at present
It connects.
The working mechanism of reinforced bar sleeve grouting jointing, is to have higher pressure resistance based on grouting material in grout sleeve
Degree, while itself also has microdilatancy characteristic, when it by grout sleeve effect of contraction when, in grouting material and grout sleeve
Larger normal stress is generated between side tube-wall, normal stress generates frictional force to reinforcing bar in its rough surface with ribbing whereby, so as to
Transmit reinforcing bar axial stress.The density of slurry directly influences the quality of connection in grout sleeve jointing.
?《Reinforced bar sleeve grouting connection application technology regulation》In, the requirement for Grouted density is answered closely knit full for grouting
Full, all grout outlets should all pulp；It is mainly connect by way of checking work progress data and examining and record to check and accept at present
Quality.It is pure to examine record by checking process, it is possible to be difficult to fully understand internal quality of connection.
There is the technology of the grouting plumpness of several detection sleeve grouting to occur in the recent period, one is based on X-ray industry CT skill
The sleeve of art is in the milk plumpness detection technique, is in the milk plumpness detection technique one is the sleeve based on pre-buried sensor method, and one
Sleeve grouting plumpness detection technique of the kind based on pre-buried steel wire hubbing, one is the sleeves based on Portable X-ray technology
Grouting plumpness detection technique, respectively there is advantage and disadvantage.
Sleeve grouting plumpness detection technique based on X-ray Industrial Computed Tomography is used for test in laboratory, can be used for examining
Survey the test specimen of process test.But it cannot really reflect live entity situation.
Sleeve grouting plumpness detection technique based on pre-buried sensor method can monitor spillage of the grouting material before solidification
Problem needs to detect if the later stage suspects node grouting quality, it is necessary to which pre-buried sensor in advance is needed to ensure random sampling observation
It will be in each grout outlet pre-buried sensor.Get off in this way, sensor complexity is high, less suitable general data, since overfall can
It can cause to judge by accident.
Sleeve grouting plumpness detection technique based on pre-buried steel wire hubbing is by special steel wire from the pulp saliva of sleeve
The flattened rebar surface position to close grout outlet side in sleeve, the gas vent that rear special steel wire in place carries rubber stopper are located at
Surface, drawn steel wire after 3 day age, judge whether corresponding sleeve grouting is full qualified by drawing load, mating endoscope
Can be put in the duck eye left after drawing judge whether it is full.The disadvantage is that cannot disturb or destroy in 3 days, at the construction field (site)
Compare and is difficult to ensure.
Sleeve grouting plumpness detection technique suitable thicknesses based on Portable X-ray technology are not more than 200mm；Sleeve list
The sleeve grouting plumpness test of the precast shear wall of row or " blossom type " arrangement.Since ray radiation is larger, away from X-ray machine X 30
It is unable to someone in rice range, so the unsuitable test for carrying out sleeve grouting plumpness at the scene.
The quality of vertical member reinforced bar sleeve grouting connection directly influences the safety of prefabricated concrete structure, with dressing
Rapid development with formula concrete structure in China, to ensure that the grouting of vertical member reinforced bar sleeve connects in prefabricated concrete structure
The quality connect, one kind is in assembled arthitecutral structure, the detection method of vertical prefabricated components reinforced bar sleeve grouting connection to be with regard to outstanding
It is important.
