Description
Technical field
The present invention relates to a kind of building roof system leakage detection method, for determining leak location.
Background technology
With developing rapidly for modern economy, structural metal roofing is excellent with its as a kind of new type roof structural system
Application property, applicability and feature, be more and more applied in modern building fabric.
The advantage of structural metal roofing is mainly reflected in intervolve and is sealedly engaged design, and building-site can be coordinated to produce and set
The roof boarding of equal length is counted, roofing also exposes without connecting port without any screw after installation, both can guarantee that building roofing
Complete appearance, and with functions such as excellent waterproof, antiseepage, wind resistance snow.
However, metal Roof system is during natural environmental condition use, undergo for a long time temperature and wind load etc. other
Factor is acted on, and will certainly produce certain influence to the fastening structure of Roof system and sealing, so as to influence Roof system to prevent
Water anti-leakage function, can produce drainage, while metal Roof system can also have room as a kind of structure of composite multi-layer
There is infiltration in outer surface but inner surface structure is intact and do not produce the phenomenon of leak, and seepage but no generation leak occur between more than
Two kinds of situations, due to the complexity of metal Roof system structure, leak location is complicated with leakage point propagation path, finds seepage
Position and it is irregular follow, if being detected on a large scale directly against building roof system outdoor face, by environmental constraints, unusual not side
Just, cost is also larger, there is presently no the detection method determined for such construction roof leakage position.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the present invention provides a kind of building roof system leakage detection method, energy
The leak location of enough Roof systems for determining seepage occurs but drainage is not produced.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of building roof system leakage detection method, for occurring seepage but not producing the building roof system of leak to ooze it
Detected, comprised the following steps in leakage position：
Step one, to building roof system mark off need overhauled or leak detection detection zone；
Step 2, a period of time after stopping rain or completing drench with rain operation of the auxiliary spray system to above-mentioned detection zone outdoor face
It is interior, temperature sensing is carried out to detection zone inner surface using thermal infrared imager, detection zone inner surface is found out by temperature difference
Doubtful seepage region；
Step 3, further determine that the corresponding outdoor face region in above-mentioned doubtful seepage region, it is ensured that in the region without the globule or
Ponding, temperature detection is carried out using thermal infrared imager to the region；
Step 4, the temperature difference analysis by the infrared thermal imaging picture to thermal infrared imager, it is accurate to determine detection zone room
The leak location of outer surface.
As the improvement of above-mentioned technical proposal, also including step 5, if step 4 cannot accurately determine leak location, to step
Detection zone outdoor face in rapid one first or reuse auxiliary spray system drenched with rain, completion drench with rain operation latter section
In time, temperature sensing is carried out using thermal infrared imager again to detection zone inner surface, building is found out by temperature difference
The doubtful seepage region of plane system inner surface, and step 3 and step 4 are repeated, until accurately determining detection zone outdoor face
Leak location.
As the improvement of above-mentioned technical proposal, the wave-length coverage of the thermal infrared imager in 8 ~ 12 μm, temperature resolution
No more than 0.1 DEG C, pixel is not less than 320 × 240, temperature-measuring range between -20 DEG C ~ 100 DEG C, the equipment steady and continuous working time
It is not less than 120 minutes.
As the improvement of above-mentioned technical proposal, spray head spray angles and the centerlines model of the auxiliary spray system
It is 15 ° ~ 35 ° to enclose, and water-carrying capacity is not less than 4L/（㎡·min）.
Used as the improvement of above-mentioned technical proposal, the spray head spray angles of the auxiliary spray system are with centerlines
20°。
Beneficial effects of the present invention have：
The present invention is applied to generation seepage but does not produce the building roof system of leak to detect its leak location, by right
The division of building roof system, temperature sensing is carried out using thermal infrared imager to detection zone inner surface, is found out in detection zone
The doubtful seepage region on surface, and the leak location of detection zone outdoor face is further determined that, contribute to early detection problem,
Solve problem.
Specific embodiment
Leak location in the present invention refers to that outside rainwater enters internal system structure from building roof system outdoor face
Particular location；Doubtful seepage region refers to region or the tool of building roof system inner surface correspondence outdoor face leak location
Body position.
A kind of building roof system leakage detection method of the invention, for seepage occurs but the building of leak is not produced
Plane system is detected to its leak location, comprised the following steps：
Step one, to building roof system mark off need overhauled or leak detection detection zone；
Step 2, a period of time after stopping rain or completing drench with rain operation of the auxiliary spray system to above-mentioned detection zone outdoor face
It is interior, temperature sensing is carried out to detection zone inner surface using thermal infrared imager, detection zone inner surface is found out by temperature difference
Doubtful seepage region；
Step 3, further determine that the corresponding outdoor face region in above-mentioned doubtful seepage region, it is ensured that in the region without the globule or
Ponding, temperature detection is carried out using thermal infrared imager to the region；
Step 4, the temperature difference analysis by the infrared thermal imaging picture to thermal infrared imager, it is accurate to determine detection zone room
The leak location of outer surface.
If step 5, step 4 cannot accurately determine leak location, to the detection zone outdoor face in step one first
Or reuse auxiliary spray system drenched with rain, completion drench with rain operation after a period of time in, using thermal infrared imager to detection
Region inner surface carries out temperature sensing again, and the doubtful seepage region of building roof system inner surface is found out by temperature difference,
And step 3 and step 4 are repeated, until accurately determining the leak location of detection zone outdoor face.
Specifically, in 8 ~ 12 μm, temperature resolution is no more than 0.1 DEG C, pixel to the wave-length coverage of the thermal infrared imager
320 × 240 are not less than, between -20 DEG C ~ 100 DEG C, the equipment steady and continuous working time is not less than 120 minutes temperature-measuring range, institute
The spray head spray angles and centerlines scope for stating auxiliary spray system are 15 ° ~ 35 °, and water-carrying capacity is not less than 4L/（㎡·
min）, spray head spray angles and the centerlines of the auxiliary spray system are 20 °.
It is very inconvenient by environmental constraints during due to being detected on a large scale directly against building roof system outdoor face, into
This is also larger, and temperature sensing is carried out to building roof system inner surface then easily, thus from the inside to the outside, is sprayed in conjunction with auxiliary
Pouring system and thermal infrared imager carry out leak detection to roofing, help raising operating efficiency, have by being accurately positioned leak location
Beneficial to the formulation of maintenance and repair scheme, human and financial resources are saved.
The above, simply better embodiment of the invention, but the present invention is not limited to above-described embodiment, as long as
It reaches technique effect of the invention with any same or similar means, should all belong to protection scope of the present invention.
