Durch die zweckmäßig ausgewählte und/oder gestaffelte Lage der spektralen Bereiche und die geeignete Beleuchtung der baulichen Untersuchungsobjekte treten optisch deutlicher als sonst üblich Gebiete eines bestimmten Bauzustandes hervor, die z. B. Gebiete unterschiedlicher Beton-, Mörtel- und Baustoffzusammensetzung (u. a. an Brücken, Schornsteinen) und solche unterschiedlicher Feuchte, Durchtränkung mit Kohlenwasserstoffen oder Ablagerungen von Salzen, auch solche unterschiedlicher Oberflächenrauhigkeit, Korrosion, Erosion oder Abradion sichtbar werden lassen, die in einem Zuge (und nicht mehr quasi punktweise von großen Flächen) erfaßt und dokumentiert werden und einer quantitativen Auswertung z. B. durch die Bestimmung von Flächenanteilen, geometrischen Form- und Lageparametern zugänglich sind.Due to the suitably selected and / or staggered position of the spectral regions and the appropriate illumination of the structural objects under investigation, it is clearer visually more clearly than usual that regions of a certain state of construction emerge, the z. B. areas of different concrete, mortar and building material composition (including bridges, chimneys) and such different moisture, impregnation with hydrocarbons or deposits of salts, even those of different surface roughness, corrosion, erosion or abradion visible in one go ( and not more or less pointwise from large areas) are recorded and documented and a quantitative evaluation z. B. by the determination of area fractions, geometric shape and position parameters are accessible.
Ausführungsbeispielembodiment
Die Erfindung soll nachstehend an Ausführungsbeispielen erläutert werden.The invention will be explained below with reference to exemplary embodiments.
1. Eine Gebäudefassade, z.B. von 10 Getreidesilos ä 40m Höhe und einem Durchmesser von ... m, wird mit einer photographischen Kamera, ausgestattet mit einem geeigneten Spektralfilter so aufgenommen, daß die Gebiete erhöhter Korrosion des Mörtels hervortreten und einer äquidensitometrischen Auswertung, z.B. mitelektronischen Verfahren zugänglich sind, bei der der Anteil und die Lage der Flächenanteile einzelner Bauzustandskiassen ausgegeben wird: auf photographischem Material, auf Bildschirm oder anderen rechnergekoppelten peripheren Geräten.1. A building facade, for example of 10 grain silos a 40m high and a diameter of ... m, with a photographic camera equipped with a suitable spectral filter recorded so that the areas of increased corrosion of the mortar emerge and an equidensitometric evaluation, eg with electronic Methods are available, in which the proportion and the position of the surface portions of individual Bauzustandskassen issued: on photographic material, on screen or other computer-coupled peripheral devices.
2. Ein Untersuchungsobjekt im Industriebau wird durch geeignete Beleuchtung z. B mit Quecksilberhochdrucklampen so wie unter 1. beschriebenen aufgenommen, daß durch diese Bereiche Beleuchtung veränderter Substanzkonzentration an der Oberfläche optisch hervortreten, was erforderlichenfalls bei der Auswahl der Beleuchtung durch spektral-optische Messungen unterstützt werden kann.2. A research object in industrial construction is z. B recorded with high-pressure mercury lamps as described under 1, that through these areas lighting changed substance concentration on the surface visually stand out, which can be supported if necessary in the selection of lighting by spectral optical measurements.
3. Eine Frontseite eines Bauwerkes wird so wie unter 2. beleuchtet und wie unter 1. aufgenommen, so daß unterschiedliche Baustoffkonzentrationen und Baustoffzusammensetzungen, z.B. der verwendeten Betone bzw. Mörtel hervortreten.3. A front of a structure is illuminated as in 2. above and taken up as in 1. so that different building material concentrations and building material compositions, e.g. emerge the used concretes or mortar.
4. Aufnahmen aus 1. bis 3. werden einer äquidensitometrischen Auswertung, z. B. mit fotographischen, optischen, elektronischen oder entsprechenden rechentechnischen Verfahren unterzogen und die Anteile, die Lage, die Größe und die Form einzelner Gebiete ermittelt und auf fotographischem Material, Bildschirm oder anderen peripheren Rechnergeräten ausgegeben und einzelnen Bauzustandskiassen zugeordnet.4. Recordings from 1 to 3 are an equidensitometric evaluation, z. B. with photographic, optical, electronic or corresponding computational methods subjected and determined the proportions, the location, the size and the shape of individual areas and output on photographic material, screen or other peripheral computing devices and assigned to individual Bauzustandskkiassen.
5. Die Zuordnung von Gebieten einer bestimmten spektralen Emission oder Remission und bauzustandsanalytischen Kenngrößen kann mit Hilfe klassischer Verfahren der Bauzustandsanalyse, z. B. der Gamma-Rückstreuung, mit Neutronenoberflächensonden oder Mikrowellenverfahren, aber auch mit chemischen und elementspezifischen Verfahren wie der Röntgenfluoreszenz oder der Aktivierungsanalyse erfolgen.5. The assignment of areas of a particular spectral emission or remission and structural state analysis parameters can be determined using classical methods of structural analysis, z. As the gamma backscatter, done with neutron surface probes or microwave methods, but also with chemical and element-specific methods such as X-ray fluorescence or the activation analysis.
