In order to finish the interior, it is necessary to attach the base material after removing the formwork, so that there is a problem that extra work and time are required. Incidentally, even in the tile pre-installation method, the time required for assembling the concrete form panel itself cannot be reduced. In addition, after removing from concrete, it is necessary to maintain the panel surface etc., and it takes time and effort to clean a large number of concrete form panels each time they are used, and there is a problem that labor is required for that. . For wooden concrete formwork panels, the number of times of diversion is small and large amount of wood is consumed due to the rapid consumption and damage due to the drilling of separators, and the improper qualification of the concrete casting surface, resulting in large cost increase. In addition, there was a problem that there was no use for conservation of nature. Steel concrete form panels can be diverted many times, but have problems such as heavy weight, inconvenient handling, and difficulty in dimensional change. Further, in the conventional separator structure, there is a problem in that the drilling of the panel surface or the large number of the panels causes troublesome construction work, and a decrease in the construction speed results in a longer process time.

The present invention has been made to solve such a conventional problem, and an object of the present invention is to eliminate the necessity of re-installing an interior foundation after detaching a concrete formwork, and a panel surface is not required. It is an object of the present invention to provide a concrete formwork panel which does not require cleaning and has a large number of diversions and can cope with different sizes.
