Description

A PONTOON FOR FLOATING STRUCTURE FOR MULTI-

The present invention relates to a pontoon for a multi-purpose pier structure, and more particularly, to a pontoon for a multi-purpose porthole structure in which at least one unit of a unit shape is arranged and upper and lower portions are closely contacted and fixed by a connecting pipe, .

In general, pontoons are used for buildings with lower specific gravity than water, and can be used on houses such as houses, various barges, water bicycle roads, floats, floats, water condition power plants, boat mooring facilities such as boats and yachts, It is used as a buoyant buoyant for the construction of a variety of offshore structures and aquariums, including playing a role as a fishing boat, a fishing port, a marine crayfish farm, a maritime promenade, a bridge or a sea fishing spot. In recent years, as the demand and spread of water sports have expanded worldwide, interest and development of pontoons are increasing due to demands and necessities of various uses and forms of marine structures.

The pontoon structure is a structure used by lifesaving and expensive ships, and it is always exposed to seawater environment including salinity, fresh water environment where ice pressure acts, and typhoon, flood, and wave, so structural stability and durability are very important. In terms of function, it should be able to be combined with various sizes and forms such as Jupontun / Fingerpontun, and it should safely protect the lines of utility lines such as power lines, pipelines, and water pipes, and enable easy maintenance. It is also to be possible to install attachments such as facilities for berthing and riding of ships.

As a buoyant material of pontoon, styrofoam with a low porosity is mainly used so that weight increase can be minimized even if water penetrates. Most buoyant materials are covered with a resin such as polyethylene, which is a styrofoam buoyancy material. The aluminum deck type pontoons are constructed of buckled materials with decks made of aluminum frames and wooden panels.

It is widely used because it can be manufactured in various sizes and shapes and it can be easily manufactured by attaching and detaching various accessories by using extruded aluminum frame. Concrete deck type pontoon is a composite type of concrete decking on buoyant material. Concrete deck, which is heavier than aluminum deck, is applied, and it is characterized by good vibration by blue or user.

However, securing the structural performance is very important because of the material characteristics that should not allow crack generation (tensile recoil) in the seawater. In the case of a concrete housing, reinforcing bars are placed in the formwork and pouring and pouring concrete is used for the reinforcing bars located in the concrete. In this case, The buoyant force is lowered.

Also, there is a difference in buoyancy depending on the difference in thickness of the concrete injected on each side, which makes it difficult to maintain a stable balance. Generally, concrete concrete, fiber reinforced concrete, and mesh reinforced concrete are mainly used as materials for manufacturing concrete pontoons. Hollow Concrete Pontoons are made of concrete shell and styrofoam core. It has the highest weight among the three types and is the most stable, making it suitable for environments that are vulnerable to the yachting facilities and typhoons of large yachts. However, there is a possibility of sinking, maintenance is not easy, and there is a disadvantage of non-mobility.

In response to this, various types of assemblies can be assembled, and there is little influence on the height and the change of the sea level. Conventionally, a method of joining pegs of a prefabricated pontoon has been mainly used, in which prefabricated pontoons of the same size are connected to each other by grooves and hooks.

However, the conventional pontoon bonding method has the possibility that the lower part is widened or unintentionally separated due to waves and buoyancy, and the pontoon pontoons of the same size are arranged in the upper and lower sides and the connecting part is unstable due to the connection by point contact There is a problem. In addition, most of them are constructed only as a bottom structure, and even when a rail is installed, there is a problem that the separated type is mainly composed of a risk of falling into seawater depending on the height and interval of the lower part of the rail.

In order to solve the above problem, the present invention provides a pontoon for a multipurpose pier for a multi-purpose pier structure in which a fixed unit shape and a pontoon structure integrally formed with side walls are combined and fixing pipes are installed at upper and lower portions to connect the structures, .

1. Composition of components of multipurpose water structure

Fig. 1 is a perspective view of a pontoon block 10 constituting a part of the multi-purpose pier structure of the present invention. The pontoon block 10 includes a plurality of central units 11 having a hexahedron shape and connection portions 12 formed on both sides of the central unit 11 and having semi-circular installation holes 14 formed at upper and lower portions thereof, And a short-circuiting unit 13 connected to one side of the connection unit 12 and formed on both sides or one side of the center unit 11. [

The pontoon block 10 used as a buoyant buoyant body is in a straight shape and all surfaces are sealed, and a top plan view is a rectangular shape in which concave and convex are repeated in the X axis direction. Also, the side plan view is a shape in which the convex shape of the rectangular shape and the shape of the semi-circular concave shape are symmetrical about the X axis.

The interior of the pontoon block 10 may have an empty space or be filled with a buoyant material such as styrofoam. A component capable of buoyancy can be used for manufacturing the components of the multipurpose water structure, and preferably, it can be made of linear low density polyethylene or the like. Linear low density polyethylene is called third polyethylene and has somewhat intermediate properties between LDPE and HDPE, but it has good balance between excellent toughness and transparency, and is advantageous in heat resistance and price. And it is also advantageous to form the side wall 21 integrally and to make a curved line such as the installation hole 14 because of excellent workability.

The short-circuit unit 13 and the central unit 11 having a hexahedral shape are different from each other in the function of being used as an aqueous buoyancy body, but they are classified according to their positions. It is the central unit 11 that is located on both sides on the straight line of the pontoon block 10 and is located between the short-circuit units 13.
