本発明は建築工事等のコンクリ−１・打ちの際に使用す
るコンクリート打設用型枠に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a formwork for concrete pouring used in pouring concrete in construction work and the like.
この種の型枠として要望される性質は、軽量で変形し難

材料がかかり、また、表面に複雑な凹凸模様を形成する
ような場合には型枠そのものの製造に相当な費用がかか
るという欠点があった。The desired properties of this type of formwork are that it is lightweight, difficult to deform, and has good peelability from concrete. By the way, the conventionally used type of formwork is made of metal, but it does not peel easily from the concrete, so it takes time and materials such as applying oil to the contact surface with the concrete. In addition, when a complicated uneven pattern is to be formed on the surface, there is a drawback that the manufacturing cost of the formwork itself is considerable.

型枠が開発された。この型枠はコンクリートとの剥離が
良好で、複雑な凹凸模様も成形し易いという利点がある

部の差が大きくなると、型枠としての厚味を大きくしな
ければならない。厚味が大きくなると重量が相当なもの
となり、作業の困難性が生じるという欠点があり、また
コストも高くなるという欠点が生じた。Therefore, in recent years, a rubber formwork has been developed that is manufactured by pouring a rubber material such as silicone rubber or neoprene rubber into a metal master mold (mold). This formwork has the advantage of good peeling from concrete and the ability to easily form complex uneven patterns. The flavor has to be big. As the thickness increases, the weight becomes considerable, which has the disadvantage of making work difficult and increasing the cost.

ンクリートとの剥離も容易に行え、かつコストの安価な
コンクリート打設用型枠を提供することを目的とするも
のである。In order to improve these drawbacks, the present invention provides a formwork for concrete pouring that can be easily produced even with complex and highly uneven patterns, is light in weight, can be easily separated from concrete, and is inexpensive. The purpose is to provide

ジンである。Reference numeral 1 denotes a base body made of easily moldable synthetic resin such as ABS resin, which is formed into a desired surface shape (triangular convex portion 1a in this embodiment) by pneumatic molding or press molding. This group 1
The body 1 has a substantially uniform overall thickness and is relatively thin, so reinforcing ribs 1b are integrally formed on the back surface to prevent deformation. 2 is a glass resin applied to the surface of the substrate 1 by a spray gun, a drain cleaner, or the like.

塗料の削減も図れる等の効果を有するものである。Therefore, when the formwork formed in this way is used to frame and then concrete is poured, since the contact surface with the concrete is the glass resin 2,
After the concrete hardens, the peeling from the concrete is very good, and since the glass resin 2 has a very smooth surface, the surface of the concrete after peeling becomes glossy, and therefore, in the painting performed in the later process, the paint does not peel off easily. The amount of coating required is small, improving workability and reducing material costs. In addition, since the glass resin 2 is hard, it is hard to be scratched, and therefore it can be easily peeled from concrete even after repeated use. Even if it is a soft synthetic resin, by coating the surface with glass resin, the surface will not be scratched even after repeated use, unlike when only synthetic resin is used as a formwork. It peels well from concrete even after repeated use over a long period of time, and since it has a synthetic resin base, it is possible to reduce the cost and weight of formwork, and it is also possible to easily produce formwork with complex surface shapes. Since the surface of the concrete becomes glossy, it is easy to paint in the subsequent process and the amount of paint can be reduced.
