3 to 5 together, the pontoon-body 1 of the present disclosure includes a lower pontoon 2 and an upper body 3. The pontoons 2 and 3 are structurally differentiated, but they are mutually combined to form an integral pontoon-body 1.

The pontoons 2 are of a twin type in which a rectangular base 21 having a long width and a long cylindrical float body 22 integrally formed on the base 21 are disposed on both sides of the pair. The pontoons 2 are filled with a floating foam to prevent sinking when the float is broken.

The outer material of the pontoon 2 may be STS, synthetic rubber, plastic, or the like if the material is a viewable material.

The support (3) includes a deck (31) rigidly coupled to the top surface of the pontoon (2). On the deck 31, a total of six vertical frames 32 are provided at three regular intervals on the left and right sides. The height of the vertical frame 32 is preferably 1 m, for example. From the four-corner vertical frame 32, a curved, specifically circular, loop frame 33 extends upward toward the plane center point of the deck 31 to form an overall arch, while in the center crossing area, (36). In the circular portion 36, a center connection portion 37, which characterizes the present invention, is formed in a semicircular shape. The circular portion 36 is supported and balanced to the center of the deck 31 by a vertically extending connecting frame 360.

4, a horizontal frame 34 having a different elevation across the vertical frame 32 is disposed on the left and right sides of the deck 31, and a horizontal frame 34 is disposed between the vertical frames 32 on the front and rear surfaces of the deck 31. [ And an arch frame 35 of a semicircular arc is provided so as to be in contact with the vertex while facing each other vertically.

The pontoon 2 according to the present disclosure has a length of 2.5 m, a width of 1.7 m and a height of 1.6 m, and can maintain a buoyancy of about 1.4 t. Therefore, it is possible to install up to about 1 ton of the body 3 except the boarding personnel. Since the planar area of the body 3 to be joined on the pontoon 2 is at least larger than the pontoon 2 so that the space on the deck 31 is widened so that at least 2-3 operators are temporarily or substantially at the pontoon- And can work.

The main body 3 of the present disclosure is mainly composed of the skeleton of the deck 31 and the frames 32, 33, 34 and 35, so that it is particularly advantageous to provide a space large enough for an operator to board.
