本発明は、一般建築構造物における雨水の浸入、漏水等
を一目で目視検査することができる建築構造物に関する
。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a building structure that can be visually inspected for rainwater infiltration, water leakage, etc. in a general building structure at a glance.
従来の建築構造物は、雨水の浸入などがあっても、浸水
の程度が軽いとそのまま看過することが多く、このよう
な状態をそのまま放置すると、浸水が拡大する處れがあ
り、また、特に、木造建築構造物の場合には、このよう
な浸水の経時的な繰り返しによって構造材に腐食をもた
らすことすらあった。また、建築構造物には、結露水が
発生し易く、このような結露の経時的な繰り返しによっ
て、浸水による場合と同様な構造材の腐食を引き起こす
虞れがあった。そのため、雨水の浸入、結露水等の有無
は、建築構造物のメンテナンス上、極めて重要な調査項
目であった。In conventional building structures, even when rainwater infiltrates, the degree of inundation is often ignored as it is only a light level. In the case of wooden building structures, repeated flooding over time could even cause corrosion of the structural materials. Furthermore, dew condensation is likely to occur in architectural structures, and repeated condensation over time may cause corrosion of structural materials similar to that caused by water intrusion. Therefore, the presence or absence of rainwater infiltration, dew condensation, etc. is an extremely important investigation item for the maintenance of architectural structures.
そして、上記調査、特に浸水の有無を調査するには、一
般に、建築構造物に放水して浸水箇所を特定する放水テ
ストを行うことにより、目視によって浸水箇所を検査す
るようにしていた。In order to investigate the above-mentioned investigations, particularly to check whether there is water intrusion, generally, a water spray test is performed in which water is sprayed on the building structure to identify the flooded areas, and the flooded areas are visually inspected.
しかしながら、従来の建築構造物では、その浸入水等を
目視検査する場合には、上述の如く、放水テストを行っ

は多くの労力を必要としていた。また、このような放水
テストは、人為的なものであるため、自然降雨等の自然
現象とは大きく異なり本来の浸水を再現するものではな
く、浸水の検査としては必ずしも適正なものとはいい難
いものであった。However, in conventional building structures, when visually inspecting infiltrating water, etc., a water spray test was performed as described above, but such a water spray test required multiple test personnel and water spray equipment. Moreover, it required a lot of effort to see the results. Furthermore, since such water spray tests are artificial, they are far different from natural phenomena such as natural rainfall, and do not reproduce the actual flooding, so they are not necessarily appropriate for testing for flooding. It was something.
また、従来の建築構造物では、結露水、給排水管からの
漏れの場所などを把握することが困難で、仮に把握でき
たとしても、斯る現象が相当程度進行した場合に初めて
目視し得るようなものであり、また、このような漏れを
検査するにはそれ専用のテストを個別に行う必要があっ
た。In addition, in conventional building structures, it is difficult to identify the location of condensed water or leaks from water supply and drainage pipes, and even if it were possible to identify the location, it is difficult to identify the location of condensed water or leaks from water supply and drainage pipes. In addition, testing for such leaks required a separate test.
従って、本発明の目的は、浸入水等の有無及び浸入水等
の場所を簡便且つ容易に一目で目視検査することができ
る建築構造物を提供することにある。Therefore, an object of the present invention is to provide a building structure in which the presence or absence of infiltrated water, etc., and the location of infiltrated water, etc. can be visually inspected simply and easily at a glance.

とする検水可能な建築構造物を提供することにより上記
目的を達成したものである。The present invention is characterized in that a water test paper carrying a chemical that reacts with water to form a color is attached to a wide area of a building structure where rainwater can infiltrate or where condensation water is likely to occur. The above objective has been achieved by providing a building structure that allows water testing.

Water seeped in by water paper,
It shows the location of each water leak and allows you to see each location at a glance.
