FIG. 2A is an overall plan view showing a pontoon according to an embodiment of the present invention, and FIG. 2B is a state diagram illustrating a state in which a heavy equipment is moving and working on a pontoon according to an embodiment of the present invention.

As shown, a pontoon for heavy equipment movement according to an embodiment of the present invention includes a float 110, a deck 120, and a fastening member 130, and a plurality of The deck 120 of the steel plate material is arranged closely adjacent to the upper side of the assembled float 110 so that the heavy equipment H used for civil engineering and construction work is stably supported even when moving or working, (110) can be safely protected from breakage.

Hereinafter, a pontoon according to an embodiment of the present invention will be described in more detail with respect to each of the above components.

FIG. 3 is a plan view of a steel plate in a pontoon according to an embodiment of the present invention, FIG. 4 is a bottom view of a steel plate in a pontoon according to an embodiment of the present invention, and FIG. 5 is a sectional view taken along line I-I of FIG. 6 is a front exploded view for explaining a combined structure of a deck and a fastening member forming an I-shaped structure around a float in a pontoon according to an embodiment of the present invention, and Fig. 7 is a front exploded view, Is a front view for explaining a coupling structure of a deck and a fastening member constituting an I-shaped structure with a center as a center.

As shown in the figure, in the embodiment of the present invention, the deck 120 is installed to cover the float 110 so as to protect the float 110 while directly supporting the moving heavy object. The deck 120 includes a main body panel 121, a support portion 122, a contact portion 123, and a connection portion 124.

The main body panel 121 has a patterned polygonal layout (shown as a rectangular layer in the figure) so that a plurality of the main body panels 121 can be arranged closely to each other. The main body panel 121 includes a fastening member 130 A plurality of main through holes 121a and a satellite through hole 121b formed in a smaller size around the main through hole 121a. Particularly, the main body panel 121 is made of a steel material, so that even when a heavy equipment such as a tank moves in contact with the upper surface, the main panel 121 can exhibit a sufficient supporting force without being damaged. However, it is needless to say that the material of the main body panel 121 is not limited to a steel sheet but may be made of a material corresponding thereto. In addition, the main body panel 121 is installed so as to simultaneously cover the upper surfaces of the plurality of floats 110. When the body panel 121 is installed so as to be able to simultaneously cover a plurality of floats 110 without depending on only one float 110, the weight applied from the heavy equipment is not concentrated in one place, do. Referring to FIG. 1, the body panel 121 of the deck 120 covers the upper surface of the three floats 110 and has a width It is illustrated as being formed in a rectangular shape. In this case, it can be seen that eight main through holes 121a are formed per one of the main body panels 121 of the deck 120. However, the width and shape of the main body panel 121 and the number of the main through holes 121a can be changed. This will be described later.

The support portion 122 of the deck 120 is formed in a ring shape along the periphery of the main through hole 121a on the bottom surface of the main body panel 121 so that the fastening member 130 can pass through the first And has a through hole 122a. The support part 122 supports the body panel 121 with respect to the upper surface of the float 110. The support part 122 of the deck 120 is made of a polyurethane material so that the body panel 121 of the steel material and the float 110 are directly So that the impact due to the movement of the heavy object is prevented from being transmitted to the float 110 through the body panel 121. [ Thereby protecting the float 110 from damage.

The contact portion 123 of the deck 120 is formed in the shape of a ring along the periphery of the main through hole 121a on the upper surface of the main body panel 121 so that the coupling member 130 can pass through the second And has a through hole 123a and comes in contact with the heavy object moving on the main body panel 121 in a protruding form. At this time, the contact portion 123 serves as a friction member so that the moving heavy object does not easily slip on the deck 120, and also serves as a speed limiter. The second through hole 123a has a larger diameter than the main through hole 121a of the main body panel 121 so that the head portion 136 of the insert bolt 130b in the coupling member 130 is inserted into the through- (121c) of the main body panel (121) in a state of being inserted into the main body panel (123a). In addition, the circumferential surface of the contact portion 123 is formed as an inclined surface 123b whose height decreases toward the outside. When the circumferential surface of the contact portion 123 is formed as the inclined surface 123b, the impact generated when the moving heavy object passes over the contact portion 123 can be alleviated. Further, since the contact portion 123 of the deck 120 is made of polyurethane material like the support portion 122, the shock of the heavy material can be absorbed and further mitigated.

The connection portion 124 of the deck 120 connects the support portion 122 and the contact portion 123 through the satellite through hole 121b to connect the support portion 122 and the contact portion 123 to the body panel 121. [ As shown in Fig. The connection portion 124 of the deck 120 is also made of a polyurethane material such as the support portion 122 and the contact portion 123 described above.

It should be noted that although the polyurethane shot (ST) of the main body panel 121 made of a steel plate, the support part 122 made of polyurethane, the contact part 123 and the connecting part 124 are different materials, By this construction, the float 110 positioned on the lower side can be effectively prevented from being damaged while exhibiting a high buffer effect against heavy equipment such as heavy equipment and tanks moving from above the float 110 It is possible to protect.

The float 110 has a hollow main body having a space portion therein as in a conventional float shown in the market, and has a ring portion 114 to be assembled by the engagement pin in a state of being adjacent to each other. However, in the case of the float 110 according to the embodiment of the present invention, the insert nut 130a of the fastening member 130 may be fixed in a state of being inserted in consideration of the fastening member 130, A deeply formed insertion hole 112 is provided. The insertion hole 112 is provided for installation of the insert nut 130a of the fastening member 130.

The coupling member 130 serves to fasten the deck 120 to the float 110 and to form an I-shaped structure together with the deck 120 to induce the deck 120 to have higher rigidity. 6 and 7, the deck 120 is installed on the upper surface and the lower surface of the float 110 disposed at the uppermost position, respectively, and the coupling member 130 penetrates the float 110 An assembly for forming an I-shaped structure together with the upper and lower decks 120 is formed by fastening and connecting the deck 120 located on the upper surface and the lower surface of the penetrating float 110 in a state. When the deck 120 and the fastening member 130 are structurally more stable, an I-shaped structure can effectively prevent the body panel 121 of the deck 120, which is made of a steel plate, from being broken due to the load of heavy equipment. Can be reduced.

The coupling member 130 includes an insert nut 130a inserted and fixed in the insertion hole 112 of the float 110 and having a female screw 132 formed at an upper end portion and a lower end portion of the insert nut 130a, A male screw 135 corresponding to the female screw 132 is formed and inserted into the insert nut 130a while passing through the main hole 121a of the main body panel 121. The insert bolt 130b ). The insert nut 130a is formed as a hollow body 131 so that the weight of the insert nut 130a can be lowered. The upper end of the insert nut 130a is formed with a relatively large engagement portion 133 as compared with other portions of the insert nut 130a, ) Insertion hole 112 without being completely inserted.

In particular, in the embodiment of the present invention, as shown in FIG. 7, the vertical wall body 125 provided in a shape interposed between the side walls of the float 110 disposed at the uppermost stage is further provided. The upper and lower ends of the vertical wall 125 are connected to each other by connecting decks 120 located on the upper and lower surfaces of the float 110. According to the structure in which the vertical wall 125 is further provided, the vertical wall 125 in addition to the coupling member 130 can form an additional I-shaped structure together with the upper and lower decks 120, The state becomes more stable. Accordingly, it is possible to more effectively suppress the problem that the body panel 121 of the deck 120 is broken or broken due to the load of the heavy equipment.

8 to 10 are a series of reference diagrams for explaining the shape and arrangement of a deck in a pontoon according to an embodiment of the present invention.

As shown, in the embodiment of the present invention, the shape and arrangement of the deck 120 can be variously modified as needed.

Referring to FIG. 8, it can be seen that the main body panel 121 is closely arranged with the deck 120 having a rectangular shape with eight main through holes 121a. In this case, the deck 120 completely covers the tops of the three floats 110, and partially covers the floats 110 adjacent to the deck 120.

Referring to FIG. 9, it can be seen that the main body panel 121 is densely arranged with a deck 120 having a square shape having four main through holes 121a. In this case, the deck 120 completely covers the upper surface of one float 110 and partially covers the adjacent floats 110.

Referring to FIG. 10, it can be seen that the main body panel 121 is densely arranged with the deck 120 having a rectangular shape with four main through holes 121a. 8, the deck 120 completely covers the tops of the three floats 110 and partially covers the floats 110 adjacent to the deck 120.
