To solve problems such that a wooden form is hard to handle due to great buoyancy during construction of a concrete structure in the sea by means of the form, such that a metal form makes work of a diver hard and makes construction costs high due to long hours of work in the sea because the metal form is assembled by a coupler such as a bolt, and such that concrete leaks out due to the formation of a gap between the form and foundation ground when unevenness and irregularities exist on the foundation ground, where the form is installed, in the sea.
Characteristically, two main bodies formed of an elastic material are made to face each other at a prescribed interval and coupled together by a spacer so as to constitute the form, and a floating body is coupled to the form or the single main body for the purpose of moving the form or the main body in the sea.
