にロウ付は後、塗装する構成であった。2. Description of the Related Art A conventional drain drainage device for an air conditioner has a structure in which a brass vibrator 100 is caulked to a substrate 102 and then painted as shown in FIG.
The structure was to be painted after soldering.

った。Problems to be Solved by the Invention However, in a structure in which brass is caulked to increase its strength, if it is made of a hard material, it becomes brittle and cracks occur due to caulking.On the other hand, in order to prevent cracking, a material with reduced strength is used. The caulking strength cannot be ensured, and there are problems with water leakage and falling off, and -
In the configuration in which carbon steel pipes for membrane structures are brazed, there are problems in that brazing is a complicated process, and the heat of brazing tends to accelerate corrosion due to the adhesion of oxide scale.
本発明は、従来の割れ、脱落等の防止、耐食性の向上を
目的とするものである。The present invention aims to prevent conventional cracking, falling off, etc., and improve corrosion resistance.
問題点を解決するための手段

しめ接続を行なった後、塗装を行なったものである。Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a carbon steel pipe for machine structural use with good workability, with copper plating of 2 to 10 μm on the inside and 1 to 4 μm of copper plating on the outside. A 4 to 7 micron unneutralized zinc unichrome plating was applied on top to improve corrosion resistance, and the connection was caulked and then painted.
作 用

。Plating 1b is performed, but if the copper plating thickness is less than 1μ, the corrosion resistance effect will be poor, so 1μ or more is required, so it is 2 to 10μ.
In addition, in consideration of improving corrosion resistance since the outer surface is exposed to the outside air, a base copper plating 1c is applied, and a zinc unichrome non-neutralized plating 1d is applied. Copper plating is a base plating, and a thickness of 1 to 4 μm is sufficient. The unneutralized zinc unichrome plating requires a thickness of 4μ or more from the viewpoint of corrosion resistance, so it is applied to a thickness of 4 to 7μ, and coating stations e and 1e' are applied.

引き抜き強度も約３割向上した。As a result of comparing the present invention with a conventional brass pipe caulking structure, it was found that in the conventional case, cracks appeared in the caulked part, and the bending shape of the pipe at the caulked part was uneven, resulting in poor adhesion to the substrate and inferior pull-out strength. However, in the present invention, there are no cracks in the caulked portion, and the adhesion between the pipe and the substrate at the caulked portion is good.
The pull-out strength was also improved by about 30%.
