Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a stretch connecting unit for a mooring device,

The present invention proposes a footing plate of a mooring device for use as a marine docking facility, a floating bridge or floating breakwaters, which is divided into a plurality of footing units, and each of the footing units is provided with a connection frame having a " And a buffer space for buffering the deformation width of the foot plate in the longitudinal direction is provided on the connecting frame or the joint member so that the thermal expansion of the foot plate generated during the summer season So that the deformation of the foot plate and the decrease in the assembling strength can be prevented.

Generally, in mooring facilities installed in water fishing facilities such as inland lakes, rivers, or coastal waters, or berths of small vessels, buoyants such as logs or styrofoam are bundled in a certain shape And then the footrests and the ship binding bits necessary for the berthing of the ship are installed on the moorings.

However, if a mooring device is installed using a buoyancy material such as a log or a styrofoam, not only a lot of manpower is required in the installation process of the mooring device, but buoyant materials are easily damaged by waves or external impact, There is a problem that the safety is deteriorated and the wastewater in which the mooring device is installed is contaminated by fragments separated from the buoyant material.

In recent years, polyethylene (PE), preferably medium density polyethylene (MDPE), which is excellent in corrosion resistance, mechanical strength and recyclability and can be easily and firmly assembled and adhered by a heat fusion method, Or high density polyethylene (HDPE) buoyancy pipes and connection brackets.

1, a plurality of buoyancy pipes 3 for providing buoyancy are connected to the connection brackets 4 so as to be regularly arranged by the connection brackets 4, as shown in FIG. 1, 1 is provided with a footrest 5 'and a safety guard 6 for moving and protecting the user on the upper side of the mooring structure 2 while providing a mooring structure 2 on the lower side, What is shown is a multipurpose mooring device, which was filed as 2009 Patent Application No. 51031 by the present applicant and is patent registered as No. 10-0935240.

The connection bracket 4 used in the above-described mooring device 1 may be of various types and forms, but generally one to three pipe rings assembled with the buoyancy pipe 3 are formed on the lower side A reinforcing brace is formed on the upper or outer side of the pipe ring and an assembling end for assembling the brace 5 'and the safety railing 6 is provided at the upper end of the brace.

The pedestal 5 'is composed of a plurality of pedestal frames 5a having a rectangular frame shape and the safety rails 6 are spaced apart from each other by a predetermined distance between the rail posts 6a And a guard rail 6b is connected along the height direction of the mooring structure 2. A mooring pipe 3a connected to the mooring rope 8 by the mooring band 7 is provided at the corner of the mooring structure 2, And a buffer bumper frame 9 is connected to the outer side of the mooring structure 2.

However, other mooring devices as well as the mooring device 1 proposed by the present applicant use a polyethylene material having a relatively large coefficient of thermal expansion as one kind of plastic. In the mooring device 1, The foot frame 5a constituting the mooring structure 2 is thinner and smaller in diameter than the buoyancy pipe 3 and is installed on the upper side of the mooring structure 2 and is directly exposed to direct sunlight or an external high temperature, There is a problem that deformation of the foot plate 5 'due to thermal expansion or the like and deterioration of the assembling strength are easily caused.

Particularly, in a large mooring device (1) such as a floating bridge (浮 棧 bridge: a pier which moves freely up and down according to the height of the water) and a docking facility or floating breakwater whose overall length is more than 100 m, Since the deformation width at which the foot frame 5a is stretched due to the thermal expansion is somewhat increased, it adversely affects the assembly strength of the entire foot plate 5 'and the appearance state of the foot plate 5', and in the worst case, The overall facility strength of the mooring device 1 is lowered, which shortens the service life of the mooring device 1.

In addition, in the installation of the large mooring apparatus 1 as described above, it is also possible to manufacture and carry the foot frame 5a having a very long length, and to perform the operation of connecting the foot frame 5a to the connecting bracket 4 In order to compensate the above problem, if the foot plates 5 'are divided into a plurality of foot plate units and are installed in a divided manner at regular intervals, As a result, the appearance of the mooring device 1 becomes very poor, and further problems such as various foreign substances easily caught at the intervals and the user's feet are easily caught.
