Description

{Prefabricated floating pier with side buffer structure}

The present invention relates to a prefabricated floating bridge with a side buffering and reinforcing structure. To describe this in more detail, it relates to a prefabricated floating bridge with a side buffering and reinforcing structure that can effectively absorb external shocks by securing the lateral durability of the floating bridge being assembled.

Typically, a floating bridge is a facility installed on the surface of the water to form a certain movement path near the coast of the sea, river, or lake, and is used as a floating bridge, floating dock, or yacht mooring site. It is used for purposes such as docks and docks, and is installed to dock ships while floating on the water.

At this time, floating bridges are mostly constructed in various sizes and shapes by connecting floating bridge units manufactured in cell units in a prefabricated manner. At this time, as the floating bridge units are fastened with simple bolt fastening methods, assembly durability is weak and they are susceptible to waves and ship collisions. When exposed to repeated loads, structural stability is not secured due to rolling and pitching.

Accordingly, in the previously disclosed registered patent No. 10-2220046, an upper structure forming a movement path, a bracket connected to the bottom of the upper structure, and a floating pipe inserted into the bracket in parallel with the upper structure and sealed at both ends and an anti-rolling pipe that is inserted into the bracket and has at least one end or side open and filled with water, a cone-shaped cap that seals both ends of the floating pipe, and a water leak installed inside the floating pipe. A technology for providing a prevention plate has been previously proposed.

In addition, in Patent No. 10-1508899, which is another prior art, a 'tube'-shaped body with a space inside, a predetermined thickness and installed in close contact with the inner circumferential surface of the body, have elastic force to absorb impact load. Consisting of an elastic pad that is elastically absorbent and removable; The body is made of a quadrangular tube whose cross-sectional shape has a 'square' inner and outer circumferential surface; On the surface of the body opposite to the surface attached to the pontoon main body, a yaw groove dug inward is formed continuously in the longitudinal direction; The yaw groove is provided with a fastening hole through which the bolt fastened to the pontoon bridge body passes and fastens, so that the head of the bolt is located inside the yaw groove, and its diameter gradually decreases as it goes toward the inside of the body. A technology in which the inner surface is made of an inclined surface to make it smaller has already been registered.

However, the above prior technologies are intended to ensure safety from external forces including waves and collisions with ships, but due to the fastening method relying on bolts, the structure (body) is easily distorted during rolling and pitching due to waves and collision with ships. If the belt-shaped impact protector (fender) was deformed and locally damaged due to the impact load, the entire section had to be replaced.

In addition, as the shock absorbing member 40 is installed on the fender bar 20 through the adapter 30, it moves along the T-shaped engraved rail 22 of the fender bar 20 together with the adapter 30, thereby reducing the arrangement spacing. Because it is easily adjusted, it has the advantage of effectively absorbing ship collision load and preventing ship damage.

In the present invention, in order to increase the coupling force between the adapter 30 and the buffer member 40, a fitting protrusion 31 is formed on the outside of the adapter 30, and a fitting groove is formed on one side of the corresponding buffer member 40 when coupled. (41) is provided to be bolted in a state of engagement with each other.

In this way, the buffer member 40 is fastened to the center of the adapter 30 by the fitting projection 31 and the fitting groove 41, so assembly precision by unskilled workers is guaranteed. In particular, the fitting projection 31 and the fitting groove ( Due to the engaging structure by 41), in the event of a ship collision, the collision load is distributed rather than concentrated on the bolt side, and the durability of the buffer member 40 is firmly maintained.

Meanwhile, the fender bar 20, adapter 30, and buffer member 40 are provided to absorb external shock by means of a shock absorption module 50.

Referring to FIG. 4, the shock absorption module 50 includes a first hollow part 51 formed inside the fender bar 20, a second hollow part 52 formed inside the adapter 30, and A buffer bolt 54 fastened to the side wall of the pontoon bridge unit 110 while penetrating the fender bar 20, adapter 30, and buffer member 40, and a head portion 54a of the buffer bolt 54 It includes a buried groove 55 formed in the buffer member 40 to accommodate it.

Here, the buried groove 55 is formed to have a depth such that the bolt head is not exposed to the outside even during maximum compression, taking into account the amount of elastic deformation through which the buffer member 40 is compressed when docking a ship.

The buffer bolt 54 is screwed to a female thread formed on the side wall of the pontoon bridge unit 110, is screwed to a nut inserted into the side wall of the pontoon bridge unit 110 and restrained to prevent rotation, or is screwed to the side wall of the pontoon bridge unit 110. It is provided to be screwed to a nut accommodated inside.

Accordingly, when an external force is applied through the buffer member 40, the fender bar 20, the adapter 30, and the buffer member 40 are elastically deformed by the first and second hollow parts 51 and 52, thereby causing impact. It has the advantage of being absorbed effectively.

Figures 5 and 6 are diagrams showing the assembly structure of an adapter using a T-type mount module of a prefabricated pontoon bridge with side buffering and reinforcement structures.

Referring to FIG. 5, the T-type mount module 32 is connected to the center of the adapter 30, and has an axial rod 32a formed in a reduced size compared to the inlet spacing of the T-shaped engraved rail 22, and an axial rod 32a. ) is installed at the end, and is formed in an expanded size compared to the inlet spacing of the T-type engraved rail (22).
