Description
Technical field
The present invention relates to the route method of leaking that produces from tectosomes such as the roof of external detection buildings, wall, floors.
Background technology
The present inventor had before proposed to find the path that leaks, the method that detects this place that leaks and the device thereof of tectosome inside such as the wall, floor, pillar by buildings, (the special public clear 61-004471 of Japanese patent gazette) implements to leak repairing work with this device.
The diagnostic method in this path that leaks " water channel ", be the gas inlet to be set in the be full of cracks place that results from the tectosomes such as wall, inject carbonic acid gas to this gas inlet, receive the carbonic acid gas that spills from the crack on tectosome surface with the gas detection instrument and confirm the leak method in crack of this reception site of path binding of tectosome inside.
Owing to can confirm the situation that reception site is connected in tectosome inside that spills of aforementioned gas inlet and carbonic acid gas, so, just can stop up the repairing work that leaks of the water channel that leaks if the waterproof packing material is filled in this gap.
But, in this detection method, owing to the place that has disposed the detecting sensor of carbonic acid gas with point type setting, so, for example be banded occasion of extending more longways in the be full of cracks of place of leaking along seam or surface decoration material, or the place that leaks is dispersed in the occasion on all etc., owing to can not hold all places that leaks, so the occasion of missing the place that leaks is just arranged.Therefore exist and difficult point such as cause leaking and have to diagnosing once more.
In addition, as original known technology, heat rays such as infrared ray are radiated on the wall, the object wall is heated into the hollow point-like, uses wall surface temperature difference that the graphical analysis that obtained by infrared camera generates and be suggested (Japanese patent gazette spy opens flat 06-018793) by the method that this temperature difference detects the float conditions of brick.
In the method, on normal part, the temperature of the brick that rises, because to behind body transferring heat energy and temperature descends, and on the floating part of brick, being blocked by floating space of the heat transmission that the temperature that rises is carried out to body, the temperature on surface with brick of floating part becomes than other normal part height.When taking this place, on the middle ignore of the image of the brick face that obtains, can produce the disorder of temperature with infrared camera.Therefore, for thin surperficial walls such as bricks, can learn the float conditions of its surfacing.
But, in the method, owing to can only know the float conditions of surfacing, so can not detect the path that leaks of the tectosome of buildings.
In addition, different therewith, blow 40 ℃～100 ℃ high-temperature gas to wall, the heating target wall, the infrared emission energy that produces from this wall with infrared emission instrumentation amount carries out to the measurement data that obtains that image analysis detects the surface of its structure or the method for inherent vice is suggested (Japanese patent gazette spy opens flat 06-258153).
But this method is not to survey the route method of leaking of buildings, and blows 40 ℃～100 ℃ the high running funds of high-temperature gas needs to wall, and is bigger in financial burden.
Summary of the invention
In view of above-mentioned actual conditions, the objective of the invention is to, provide can be fairly simple and detect economically leak path, use the small-sized and easy carrying of device, can hold the detection method in the path that leaks of buildings reliably.
In order to solve above-mentioned problem, the detection method in the path that leaks of a kind of buildings of the 1st technical scheme of the present invention, it is characterized in that, be pressed into the temperature difference air E that can detect temperature difference with respect to the temperature of this tectosome from be full of cracks peristome with the infrared ray sensing camera as the inboard of the tectosome of the buildings of detected object, this temperature difference air E is heated atmosphere by the well heater that has temperature control part or by the air cooling machine that has temperature control part atmosphere is cooled off and obtains, with the state of infrared temperature sensing camera from the ejiction opening periphery that is cooled after having of this tectosome leaked the state of this temperature difference air E of possible surperficial place ejection and/or this temperature difference air E ejection, temperature distribution state is outputed on the monitor and make its image conversion, partly specify the possible place that leaks from the temperature difference of the part among the image G of this photographsization, represented, next, equally be pressed into carbonic acid gas K with aforementioned from the be full of cracks peristome of the inboard of tectosome, while describing aforementionedly have the appointment place that leaks possible to detect this carbonic acid gas K, determine the peristome in the path that leaks of tectosome from this detection position with gas sensor.Description of drawings

Embodiment
Embodiments of the invention are described below with reference to the accompanying drawings.
The detection method in the path that leaks of buildings of the present invention, at first mensuration becomes the temperature of the outside wall surface of the buildings of checking object.This detection method for example, can be used infrared temperature described later to detect camera or directly contacts the Temperature Detector of wall.
Set its outside wall surface and can detect the effectively air themperature of identification of camera by infrared temperature.The setting of this air themperature, the susceptibility that detects camera because of the infrared temperature that uses is different, if common infrared temperature detects camera, as long as there is the temperature difference more than 1 ℃ just enough.
For the air (temperature difference air) that forms this design temperature, there are occasion that forms by the well heater 9 that has temperature control part 10 and the occasion that forms by the air cooling machine 11 that has temperature control part 12.
Select wherein any by at that time environment and the relation of well heater or cooler decide.
For example, when summer high temperature, when outside wall surface at high temperature has heat, can use cooler to form and make the temperature difference air than the low cold air of outside wall surface and with it.In addition, in the cold time in winter, when outside wall surface becomes low temperature, use well heater to form and be comparatively ideal as the temperature difference air it than the high heating installation of outside wall surface temperature.Reason is to detect camera for infrared temperature, outside wall surface is red when high temperature, to become blueness if blow out the temperature difference air lower than its temperature, thereby improved discernment, on the contrary, outside wall surface is blue at low temperature situation, will become redness if blow out the temperature difference air higher than its temperature, thereby improve discernment.
In the internal cracking 5 of tectosome 1, be pressed into the temperature difference air E (with reference to Fig. 1, Fig. 2) of above-mentioned heating or cooling from the be full of cracks opening portion 3 of the inside of tectosome 1.
Method of press-fitting for the temperature difference air E of aforementioned high temperature, the whole bag of tricks is arranged, for example, as shown in Figure 1, what handlebar had the open airtrapping of a small size S of place is close on the inside that air nozzle 8 is crimped on tectosome 1 and the method for force feed temperature difference air E continuously in the S of this airtrapping place.
Subsequently, this temperature difference air E perhaps waits for its temperature to the periphery transmission from tectosome 1 surface ejection, detects camera 7 with infrared temperature its surperficial a is photographed and its temperature distribution state of image conversion.
Bulged-in temperature difference air, its heat energy is dispelled and by the absorbed in space during beginning, and the air of ejection is difficult to express the temperature difference of itself and outer wall.But through certain hour, the heat absorption of space material relaxes, and is maintained from the temperature that is pressed into air of producing by boasting therebetween.Then, when its temperature difference reached infrared temperature and detects the temperature difference that the photograph function discerns effectively, temperature difference was expressed as clear and definite image (with reference to Fig. 3) there.
At this moment, the object that in image, shows, existing expression from the occasion of the state of the temperature difference air (E) of the surface ejection that having of this tectosome leaked possible and the occasion of the state of the periphery of the ejiction opening of representing to be cooled after this temperature difference air (E) ejection, also can be a side or its both sides wherein.
This image processing apparatus is made of infrared temperature sensing CCD camera 7, computing machine 15, monitor 16 and input medias such as keyboard and mouse, and the reflection of being caught by infrared temperature sensing CCD camera 7 is stored on the storer of computing machine 15 and output image from the monitor 16.Print and preserve by color printer 17 then.According to the analysis of this image G, can specify from image (G) place of the danger that the temperature difference of the part of expression partly leaks.
At this moment, because this image G all carries out image conversion to outside wall surface as object, no matter be banded or the occasion that is dispersed into a plurality of places so become the ejection place of leakage cause, can have the ground of omission and hold that it is all.
With said method outside wall surface as object, can specify all pictures in the possible place that leaks, still, this wherein handlebar make the diffusion of temperature difference air from the ejiction opening in a place along seam and as the occasion (with reference to Fig. 4 A, B) of banded picture catching.In this occasion, when the place of the appointment of above-mentioned graphical representation is caught as the reason place that leaks fully, will enlarge the scale that the construction site that leaks also bootlessly increases engineering.
Therefore, as the method for confirming scupper more reliably, be to carry out determining of the real reason place that leaks by identification gas.
Specifically, the same with the occasion of temperature difference air, from the be full of cracks peristome of the inboard of tectosome, be pressed into identification gas K (with reference to Fig. 5) by the carbonic acid gas of the liquefaction gas bomb 14 that brings etc.So, identification gas can be pursued the Lu Jingcong surface place ejection about the same with the occasion of temperature difference air, its position is specified by the reflection and the Flame Image Process in above-mentioned place, on one side can catch all pictures, omits the ejection place that identification gas is checked on ground Yi Bian describe to specify the place not have simultaneously.
And, when proceeding to check by this identification gas, the occasion that is detecting by carbonic acid gas for example, owing to can under the concentration of ppm unit, carry out the detection of gas, so can detect the higher place of concentration in the ejection place, thereby the place that shows maximum concentration among the ejiction opening can be defined as the highest place of probability as the real place that leaks.
So,, can determine real leakage cause place with the detection of identification gas by all pictures in the ejection place of catching by the temperature difference air, can high-level efficiency and with the place that leaks of accuracy rate detection exhaustively.
If determined the place that leaks, be pressed into a mouthful method that is pressed into the filling agent that is used for waterproof, the repairing work in the place that can easily leak by the identification gas that uses the determining of the place that leaks from this with detection method of the present invention.
The present invention is a method as described above, when the inboard implantation temperature difference air of the be full of cracks from the tectosome that is present in buildings, the temperature difference air is from the table side ejection of this be full of cracks, perhaps, temperature difference air by ejection makes the periphery of be full of cracks portion rise or descend than the portion temperature that does not have be full of cracks, and temperature difference shows on the face side of tectosome.
When taking this temperature difference with infrared camera, the region representation of high-temperature portion or low-temp. portion is among image G, even it is banded or be distributed in the occasion in a plurality of places, also can have and omit ground and hold all of the ejection place that becomes leakage cause, next, when detecting by identification gas, can detect and spray the higher place of concentration in the place, its result, can determine the highest place of probability as the place that really leaks, can high-level efficiency and survey the place that leaks with accuracy rate exhaustively.
At this moment, because the temperature difference air does not additionally use the gas in the bottle of packing into, so cost is cheap, and the identification gas of Shi Yonging owing to being used for determining to leak the highest place of accuracy rate, place, so use amount seldom just can be finished, is economical thereafter.
