Description

[Detailed explanation of the idea] (Industrial application field) This invention relates to a floating pier.

(Prior Art) In conventional floating piers, there was not a suitable structure for connecting the main deck and the auxiliary deck, and it was difficult to attach the auxiliary deck. In addition, distortion and deflection were likely to occur between the main deck and the auxiliary deck, and there were cases where the ship lacked stability when placed above the water surface.

In addition, water and sewage pipes, telephone cables, etc. were placed along the length of the main deck below the outer surface. However, this structure not only spoiled the beauty of the floating pier, but also caused water pipes, telephone cables, etc. to be damaged by small animals such as rats and weasles. In such cases, repair work for cables and the like is time consuming and costly. In addition, because it was difficult to install cables, etc., the cost of installing the floating pier increased.

(Purpose of the invention) The purpose of this invention is to improve the connection structure between the main deck and the auxiliary deck, and to form a space partitioned by the edge materials, lids, etc. that make up the main deck, and use this space as a piping space. The aim is to solve the problem of improving the piping structure by doing so.

(Effects of the Invention) As explained above, according to the present invention, a flexible and highly rigid connection structure can be obtained. In addition, the first, second, and third grooves of the edge material are not only used for simply attaching connecting members, but also have general-purpose functions such as attaching cleats for attaching handrails, and are extremely useful.

Furthermore, according to the present invention, telephone line cables, water and sewage pipes, etc. can be stored inside the main deck. Therefore, not only can the beauty of the floating pier not be spoiled, but also telephone cables, water and sewage pipes, etc. can be protected from small animals such as rats and louses. In addition, since the lid is detachable and covers the upper part of the gap between the edge material and the deck, piping work can be easily performed. As a result, the number of personnel, time, processes, etc. required for construction can be significantly reduced, making it possible to provide inexpensive products.

Furthermore, in the present invention, a plurality of support members are used, and only these support members can support telephone line cables,
Since it supports water and sewage pipes, etc., it prevents dirt from accumulating at the bottom of the piping space and prevents small animals from building nests, making it more rational.

(Another Embodiment) FIG. 18 shows the structure of a large main deck 280 of a large floating pier that is used when providing a rest area, coffee shop, etc. In the embodiment of FIG. 18, the main deck 280 includes a plurality of main decks 1
It is constructed by connecting in parallel. 282
are connecting members having an H-shaped cross section that fit into the first grooves 18 of the adjacent main decks 1, and are solid single-piece molded parts. The material of the connecting member 282 is hard rubber.
Metals such as aluminum and stainless steel, or wood if strong enough, are used.

According to the above structure, by arbitrarily arranging a plurality of main decks 1 in parallel, a large main deck 2 with a desired area can be created.
You can get 80.
