Description

Assemblable Type Bouyancy

The present invention relates to a prefabricated buoyant body, and more specifically, it relates to a prefabricated buoyant body which can be used as a boat mooring station or a yarding facility such as a boat or a yacht, or a floating bridge that floats on the sea surface, The present invention relates to a prefabricated buoyant body which can be easily assembled and used in various forms.

Generally, a buoyant buoyant body is used as a boat mooring yacht such as a boat or a yacht, or as a yarding facility, floating on a sea surface and serving as a bridge, and various marine structures. Recently, There is a lot of interest and development due to the necessity of marine structures for use.

Such a prefabricated pontoon eliminates the structural weakness of a conventional yawing facility made of wood, such as a plate material, for the purpose of berthing a boat or a yacht, and makes it difficult to approach the yawing surface due to changes in the height of the sea surface of the concrete structure, Thereby eliminating the effort and cost of installing the facility.

A conventional prefabricated pontoon is disclosed in Korean Patent No. 10-1060086 entitled " Prefabricated pontoon equipped with technology ".

The above-mentioned prior art is a prefabricated pontoon which constitutes an outer shape by a hollow-shaped main body having a hollow portion formed therein with an airtight space formed therein, wherein a mounting groove is formed on an upper surface of the main body, a tuck is placed on the mounting groove, And a fastening member having a rod shape and having a rod shape extending along the outer circumferential surface and integrally formed with a flange is insert-blow molded, and a fastening member is fastened with a bolt passing through the fastening body, At least one drain hole is formed in the rim portion, and a step portion for supporting the tuck is formed in the periphery of the insertion portion of the upper surface of the main body into which the fastening member is inserted so as to form a drainage path between the tuck and the mounting groove.

However, the above-described conventional prefabricated pontoon is stably engaged only in the stacking in the vertical direction, and the lateral coupling is formed by the annular part in a substantially point-contact coupling manner, so that the problem of being unintentionally separated by the external water pressure, Due to such a coupling method, the pontoons are momentarily moved around the jointed portion by the external load so that the upper surface formed by the pontoons forms irregularities, thereby forming an unstable upper surface have.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to solve the above-mentioned problems and to provide a bumper having a plurality of bumper members having durability sufficient to withstand external water pressure, load, etc., The present invention also provides an assembly type buoyant body which can be stably used by allowing the upper surface of a plurality of buoyant bodies to maintain a flat surface.
