Description

The present invention relates to a tester for detecting and confirming that a chemical has been applied or spread on a concrete structure.

  A concrete surface that penetrates deeply into concrete by applying or spraying on the surface of the concrete structure, or exhibits water repellency and other effects near the surface of the concrete, suppressing concrete deterioration and extending the durability of the concrete. Protective materials, modifiers, and water repellent materials have attracted attention in recent years, and demand is expanding. However, the construction method using a highly transparent chemical has been regarded as a construction method in which the construction quality is difficult to manage, because there is no noticeable difference in the appearance immediately after completion. Among concrete surface protective materials used in the same process, a highly reliable coating amount management technique has been established for silicate-based materials. Such a management technique is disclosed in the following patent document.

JP 2007-178210 A

However, with the above technology, it is not possible to deal with materials other than silicate-based materials, and as current conditions diversify, there is a wide range of appropriate materials. High-performance construction management requires a lot of labor and time, and it is difficult to respond to the post-inspection established with silicate materials.
In view of this, the present invention can easily and reliably visually confirm that an appropriate amount of the concrete surface protective material is applied to the surface of the concrete structure even for the concrete surface protective material that is difficult to control the construction quality other than the silicate system. The object is to provide a novel method that can be objectively confirmed.

The present invention is a tester for detecting that a drug is applied or spread on the surface of a concrete structure, and is impregnated with a dye or pigment, and the dye or pigment is qualitatively reacted with the drug. A qualitative detection unit capable of eluting and a confirmation unit colored by the dye or pigment eluted from the qualitative detection unit.

It is preferable that the range colored by the dye or the pigment in the confirmation part is proportional to the amount of the dye or pigment infiltrated into the confirmation part. Moreover, it is preferable to further provide a scale representing the infiltration amount of the dye or pigment in the confirmation unit. Furthermore, it is preferable that the qualitative detection unit has a water-absorbing base material into which the drug can infiltrate, and the dye or pigment is an oil-soluble substance. In addition, it is preferable that the qualitative detection unit is dried while being impregnated with the dye or pigment. And, when the application amount or the spraying amount of the drug that is a reference in the concrete structure is defined as the reference amount, the confirmation is performed when the elution amount of the dye or the pigment in the qualitative detection unit exceeds the reference amount. The part is preferably colored. Here, it is preferable to further include an infiltration adjusting unit that contacts the qualitative detection unit and infiltrate the drug, and the drug reaches the qualitative detection unit via the infiltration adjustment unit . Moreover, it is preferable that the said infiltration adjustment part adjusts the coloring conditions of the said confirmation part. Furthermore, it is preferable that the infiltration adjusting unit has an infiltration port through which the medicine passes through the qualitative detection unit.

The confirmation unit preferably has a permeable base that can be impregnated with the dye or pigment. Moreover, it is preferable to further include an adhesive part that attaches the qualitative detection part and the confirmation part to the concrete structure, and a blocking part that is disposed between the confirmation part and the adhesive part. Furthermore, the chemical is preferably a concrete surface protective material.

ADVANTAGE OF THE INVENTION According to this invention, it can detect and confirm that the chemical | medical agent was apply | coated or spread on the concrete structure. In addition, by storing the tester used for this detection / confirmation, it is possible to record the execution of chemicals in the concrete structure.

It is a perspective view which shows Embodiment 1 of this invention. It is a perspective view which shows Embodiment 2 of this invention.

Embodiment 1 of the present invention is shown in FIG. The qualitative detection unit 2 is configured by impregnating a permeable base material with a dye or a pigment, and contacts the confirmation unit 3 . The confirmation unit 3 attaches a scale for confirming the coating amount to the permeable substrate, and has a transparent cover 4 for protection on the surface. The blocking part 5 is made of a material that does not penetrate a general liquid substance such as plastic, and blocks the penetration of a drug or the like from the back surface of the tester. The adhesive part 6 is used for attaching the tester to the structure.

A second embodiment of the present invention is shown in FIG. The infiltration adjusting portion 1 is composed of a permeable base material, the infiltration port 2 is exposed to the outside, and the other portions are covered with the transparent cover 3 and have a scale that serves as a guide for the amount of drug applied throughout. The qualitative detection unit 5 is configured by impregnating a permeable base material with a dye or a pigment, and the dye or pigment is eluted by the component of the medicine reached through the infiltration adjusting unit 1. The confirmation unit 6 is made of a permeable base material and can be colored with a drug containing a dye or pigment eluted from the qualitative detection unit 5 so that the result of the qualitative detection of the drug can be confirmed. The blocking part 4 is made of a material that does not penetrate a general liquid substance such as plastic, and blocks the penetration of a drug or the like from the back surface of the tester. The adhesive portion 7 is used for attaching the tester to the structure.
“Effect of Embodiment 1”
According to this embodiment, a dye or pigment from the qualitative detection unit 2 is qualitative chemical solution applied to the qualitative detection unit 2 is specified by eluting. Further, the amount of the colored drug infiltrating into the confirmation unit 3 can be confirmed by a scale. The blocking part 5 prevents the medicine from infiltrating from the back surface, and the adhesive part 6 is used by sticking to the structure.
“Effect of Embodiment 2”
According to this embodiment, the amount of the liquid medicine applied to the infiltration port 2 can be confirmed on the scale attached to the infiltration adjusting unit 1. When the liquid medicine reaches the qualitative detection unit 5 when the required amount is applied, the confirmation unit 6 may be colored by elution of the dye or pigment contained in the qualitative detection unit 5 due to the qualitative property of the drug. I can confirm. The blocking part 4 prevents the medicine from infiltrating from the back surface, and the adhesive part 7 is used by sticking to the structure.
