DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, Puntung according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 shows a Puncture according to a first embodiment of the present invention. Referring to FIG. 1, the Puntung 1 according to the present invention includes a body 100 formed in a buoyant space 110 and formed of a concrete 101 and reinforcing fibers 102.

The main body 100 is formed in a rectangular box shape, and a buoyancy space 110 for providing buoyancy is provided inside. The body 100 may be made of a reinforced concrete structure in which concrete is placed on the skeleton of the reinforcing bar so that the body 100 can be rigidly formed by an external impact.

On the surface of the main body 100, a coating film 120 made of glass fiber is formed for waterproofing. Alternatively, the surface of the body may be coated with a waterproof paint to form the coating 120, or may be formed of glass fiber reinforced plastic (FRP), polypropylene (PP), polyethylene (PE) It can be either one. The coating 120 formed on the surface of the main body 100 prevents water from penetrating into the main body 100 to weaken the strength of the concrete.

The body 100 may further include a cushioning member (not shown) formed of a soft rubber material having an elastic force so as to easily absorb an impact upon collision between the ship and the body, (Not shown) that can connect the bodies adjacent to each other in the width direction or the direction orthogonal to the longitudinal direction.

The buoyancy space of the main body 100 may be divided into a plurality of closed spaces separated from each other by the partition walls. In this case, since the buoyancy space of the main body 100 is divided into a plurality of closed spaces separated from each other by the partition walls, a part of the outer circumferential surface of the main body 100 is broken and water flows into the adjacent closed spaces It is possible to prevent water from flowing into the main body 100, thereby allowing the main body 100 to maintain a constant buoyancy.

The main body 100 is made of cellulose fiber as the reinforcing fiber 102, but other reinforcing fibers may be applied. As an example, it may include glass fiber or carbon fiber.

The mixture of the concrete 101 and the reinforcing fiber 102 constituting the main body 100 is obtained by cutting the cellulose fibers into 1 to 3 mm and mixing them with water to make a slurry state and putting the slurry cellulose fibers into the concrete The concrete and the cellulose fiber are mixed in a mixer so that the cellulose fibers are appropriately dispersed in the concrete.

The concrete may include aggregates such as cement, sand, gravel, and the like.

The cellulosic fibers may have a diameter of 10 to 20 탆, preferably 14 to 17 탆. The cellulose may be cut so that the number of fibers contained per g is 1,600,000, the density is 1 to 1.5 (g / cm 2), and the surface area of the entire fiber strands per 1 g is 25,000 (cm 2 / g).

Alternatively, the cellulose fibers may be cut to a length of 1.0 to 3.0 mm, a diameter of 5 to 30 μm, and a surface area of 10,000 to 40,000 cm 2 / g, followed by pressing to produce a cellulose compressed fiber sheet. At this time, the number of fibers contained per 1 g of weight may be 50,000 to 3,000,000.

The reason why the cellulosic fiber has a unit length of 1.0 to 3.0 mm is that when it is 1.0 mm or less, a sufficient length required for attachment can not be secured and the reinforcing effect is reduced. When the fiber length is 3.0 mm or more, And the fiber tends to entangle within the concrete. As a result, slump degradation occurs at the same mixed water and cement mixing ratio, so that the same amount of mixed water is used in order to obtain the same workability. As a result, the compression strength and durability .

The reason why the surface area of cellulosic fiber is 10,000 ~ 40,000cm2 / g is that the contact area of cement paste and fiber in concrete is less than 10,000㎠ / g, Is difficult. If the surface area is more than 40,000 cm 2 / g, the tensile strength of the unit fiber decreases due to a decrease in the thickness of the unit fiber, resulting in a decrease in adhesion with concrete.

Therefore, it is suitable to manufacture the impact resistant concrete by securing 5 to 30 탆 diameter of cellulose fibers and 50,000 to 3,000,000 fibers contained in 1 g. In addition, it is mixed with 100 to 500% by weight of water based on the weight of the cellulose fibers, mixed in a slurry state, and then spun into a slurry state before mixing with the concrete. This is because the cellulose fibers are homogeneously mixed with the concrete, Because it can prevent the phenomenon and shorten the mixing time in concrete production.

FIG. 2 is a view showing a Puntung according to a second embodiment of the present invention. Referring to FIG. 2, Punctum 2 according to the present invention includes a main body 100 and a floating block unit 200 having a first waterproof layer formed on its surface. The main body 100 described below is the same as the main body 100 of the Puntung 1 according to the first embodiment of the present invention having the buoyancy space 100 and including the concrete 101 and the reinforcing fiber 102 So redundant description is omitted.

A plurality of floating block units 200 are disposed in a buoyancy space of the main body 100. The floating block units 200 are formed in a rectangular parallelepiped or cubic shape so as to be disposed adjacent to each other in a buoyancy space of the main body 100 do. The floating block unit 200 is made of materials such as Expanded Polystyrene (EPS), Urethane foam, etc., which have a smaller specific gravity than water and are light and waterproof.

The floating block units 200 prevent water from flowing into the buoyancy space when a part of the main body 100 is broken. That is, each floating block unit 200 does not directly block the inflow of water but restricts the space in which the inflow of water into the buoyant space 110 is maintained, thereby maintaining the buoyancy of the main body 100 constant.

A first waterproof layer is formed on the surface of the floating block unit 200. The first waterproof layer may be formed in such a manner that when the water introduced through the damaged portion of the main body 100 is left in contact with the surface of the floating block unit 200 for a long period of time, To prevent penetration into the surface. Here, the first waterproof layer may be formed by coating with a waterproof material such as glass fiber or a conventional waterproof paint.

Meanwhile, FIG. 3 shows a Puntung according to a third embodiment of the present invention. Referring to FIG. 3, the Puntung 3 according to the present invention includes a main body 100, a floating block unit 200 including a cover portion 230 and a buoyancy layer 240.

The floating block unit 200 includes a cover portion 230 having a filling space therein and sealing the filling space from the buoyancy space of the main body 100 and a buoyancy layer 240 filling the filling space.

Even if a plurality of floating block units 200 are mutually disposed in the buoyancy space of the main body 100, water permeable gaps are formed at portions where the floating block units 200 mutually abut. When the outer circumferential surface of the main body 100 is broken, the water penetrating into the gap through the damaged portion increases the weight of the main body 100, thereby reducing buoyancy of the main body 100. At this time, And blocks the water from penetrating into the gap of the floating block units 200. [

The second waterproof layer 300 is formed by filling urethane or the like between the gaps of the floating block units 200 and the first waterproof layer 210 so that water does not directly contact the first waterproof layer 210 of the floating block unit 200 And it is preferable to fill the inner circumferential surface of the main body 100 so as to be in close contact with the inner circumferential surface of the main body 100.
