Description

Reinforcing panel and Method of reinforcing the edges of the construction of harbor}

The present invention relates to a reinforcement method of an offshore structure, and more particularly, to a reinforcement method for preventing the destruction of the edge portion of the offshore structure, damage to the ship, and the like.

Marine structures, in particular, bridges, water tanks, or quay walls, are corroded by salt water, sulfates, salts, and the like, and the edges are easily damaged by the arrival and departure of various types of ships and the impact and friction of anchored ships and waves. In particular, when destruction of a part of the structure occurs due to the impact of the ship, a dangerous situation such as a serial collapse can be caused.

Therefore, it is necessary for the marine structure to have reinforcing means for reinforcing impact resistance at its corners, and elastic means such as waste tires have been used to prevent damage to the ship, but this was not good.

The reinforcement means used in the past had a method of using a steel sheet. Specifically, the steel sheet material is bent rounded corners in a L-shape to form a predetermined protective film on both sides, and then reinforced with an iron core such as a mesh inside, filled with cement mortar or concrete, cured, and then rusted on the surface of the iron plate. The situation was painted as a coating for prevention. However, the reinforcing means by the steel plate was very vulnerable to salt water, and it was necessary to periodically carry out maintenance checks such as repainting because it was oxidized and corroded for a long time. It has been a factor that causes. In addition, the above elastic means are still needed to protect the moored vessel.

The main object of the present invention is to provide a reinforcement method that can protect and reinforce the coastal structure semi-permanently without the need for continuous maintenance in a single construction.

Another object of the present invention is to provide an elastic means capable of protecting a vessel anchored on the shore without harming the aesthetics.

To this end, the reinforcing means or reinforcing method of the present invention should be provided so that the material of excellent corrosion resistance to wear resistance to contact the external environment, a means for improving the rigidity of the concrete structure. More preferably, the construction method should be simple, and it is necessary that the construction cost is low without harming the aesthetics.

The reinforcement method of the coastal structure according to the present invention for achieving the above object, the rigid reinforcing step of bonding a high tension panel having a high tensile strength to improve the rigidity of the concrete structure to the edge of the concrete structure; Attaching an elastic member to provide a shock absorbing function to prevent breakage of the berthing vessel; And a protective layer placing step of providing a protective layer on a surface thereof to protect the elastic member.

Hereinafter, with reference to the accompanying drawings an embodiment of the present invention will be described in more detail.

1 is a side cross-sectional view of an existing edge portion 1, namely, a construction site, such as a marine structure, for example, a bridge, a water cage, or a quay wall. In general, the construction site, which is a concrete structure, has a rough surface. The construction site also has partial cracks 4 to 3 when the structure is old. Reference numeral 2 denotes a barrier boundary stone.

Embodiments of the present invention require a smooth construction surface. For this purpose, the cleanup operation of chipping and blasting is carried out. In addition, the cracked or damaged portion is filled by pouring epoxy mortar. Severely damaged areas can also be reinforced by pouring cement mortar.

2 illustrates a state in which the high tension panel 10 is adhered to or adhered to the ground-constructed construction surface 11. Reference numeral 12 denotes a layer such as epoxy mortar or cement mortar that can be poured onto the construction surface. The high tensile panel 10 has a high fire resistance and durability, it is necessary to have a high tensile strength, it is preferable to use a material of synthetic resins. For reference, such a high tension panel 10 is recommended a high tension panel according to the patent application No. 99-36801 proposed by the present inventors.

The high tension panel 10 has an L-shaped cross section so as to reinforce the upper and side surfaces of the structure at the same time, the bent portion is preferably formed integrally to be rounded. The high tension panel may be bonded by a predetermined adhesive. The adhesive is preferably an adhesive of epoxy resin, and can be applied to the construction surface by spraying.

3 shows a state in which the elastic member 20 for shock absorption is adhered or attached to the upper surface of the high tension panel and the protective layer 21 is poured and completed in construction.

The elastic member 20 is preferably a synthetic rubber plate and the impact portion is provided in a considerable thickness so as to have sufficient absorbing power. The elastic member may be provided in a concave-convex type, rather than the same thickness over the entire length to double the shock absorbing effect.

The elastic member installed at the corner of the construct may be provided in a U-shape like a high tension panel. For example, the thickness of the elastic member is preferably about 20-40 mm. As shown in the figure, the elastic member 20 may be fixed to the upper surface of the panel by anchor bolts 22, or may be adhesively fixed by an adhesive of epoxy resin.

The protective layer 21 is formed by applying a uniform thickness of an elastomer of polyurea to the entire construction surface to which the elastic member is attached. The elastic member 20 and the high tension panel 10 are firmly fixed by an elastomer, which is an elastomer, protected from external shock, and the shock absorption function is improved.

On the other hand, the space that can remain between the construction surface and the elastic member and the high tension panel is filled by a liquid adhesive sprayed through a predetermined injection port (23). To this end, an inlet and an exhaust port (not shown) are formed on one side of the elastomer. The adhesive is excellent in adhesiveness, and a material that can compensate for the difference in physical properties between the high tensile panel and the elastic member, for example, an epoxy resin is preferable.

The high tensile panel 30, which is a rigid reinforcing means, and the rubber sheet 31, which is an elastic reinforcing means, may be provided integrally (see FIG. 5A). That is, by providing the high tension panel 30 in the state where the rubber sheet material 31 is bonded on the producer side, the builder can be more easily constructed.

In addition, the protective layer, the high tension panel and the elastic member may all be provided as an integral reinforcement means. The construction method according to this is to attach and fix the reinforcing means to the construction surface using an adhesive or anchor bolt, and then additionally spray the polyurea elastomer on the edge portion and the anchor bolt portion.
