る。(Prior art) As is well known, if a synthetic resin is bonded under atmospheric pressure to an uncured concrete surface with a wet surface, the adhesive strength will be almost zero due to the moisture in the concrete. . If the concrete surface and the synthetic resin do not have a solid foundation, water from rain, snow, etc. that can enter even through the slightest gap between the concrete and the synthetic resin will not be able to penetrate the concrete surface.
It dissolves alkaline substances such as calcium hydroxide contained in ~, causing the synthetic resin to deteriorate, and in winter, it freezes, increases in volume, and spreads the adhesive surface, completely separating the concrete ~1 and the synthetic resin. This may result in a loss of information. Therefore, it is necessary for the concrete surface to be sufficiently hardened and dried during construction and production, and the quality of construction objects and products coated with synthetic resin is determined by their adhesive strength.

Elastic PC made by casting C sleepers and covering them with elastic urethane resin.
The sleepers are made by polishing the hardened and dried surface of the sleepers, and then bonding urethane resin by pouring and bonding them using the RIM method (RIAXICON injection mold method) through a formwork.

しかし］ンクリー面を完全に乾燥させるには日数を要し
、Ｄ１磨処理やプライマー処理はその工程が極めて煩雑

着可能とした接着方法を提供することにある。Therefore, the object of the present invention is to provide an adhesion method that enables the adhesion of synthetic resin even to uncured concrete surfaces that have not sufficiently dried, with an adhesive force equal to or greater than that of hardened and dry concrete surfaces. It is about providing.

のと考えられる。(Function) By the way, in order to investigate the cause of this, a scanning electron microscope was used to examine the adhesion surface obtained by the vacuum adhesion method according to the present invention and the adhesion interface between the two using the adhesion method under atmospheric pressure. i! As a result, the adhesive interface under atmospheric pressure can be clearly observed, but the contact interface created by the vacuum adhesive method is hardened when the concrete and synthetic resin are in contact with each other. I couldn't grasp the interface. However, this vacuum bone bonding method using reduced pressure treatment improves adhesive strength by infiltrating liquid synthetic resin into the four minute parts of the concrete surface layer and removing air bubbles in the synthetic resin. Conceivable.

め、生産効率および品質が格段に向上する。(Effects of the Invention) Therefore, according to the present invention, the degree of adhesion of the bonding surface is significantly improved, and it is particularly effective in bonding 6 between uncured concrete containing a large amount of moisture and synthetic resin, so that, for example, sleepers can be sufficiently cured and dried. Even if it is not, it is possible to obtain normal adhesive force, and of course, if it is sufficiently dry, the bonding force can be increased by 1
I can do 17 things. As a result, the number of days required for curing and drying PC sleepers and the like is extremely shortened and the adhesive strength is improved, so production efficiency and quality are significantly improved.

処理法であることが明白である。The table above shows that if concrete is cured under reduced pressure for even just a few days, a greater bonding force can be obtained than when bonding under atmospheric pressure to a sufficiently hardened and dry surface. It is clear that this is an excellent adhesion-improving treatment for surfaces.
