ものである。[Detailed Description of the Invention] <Industrial Application Field> The present invention is mainly applicable to loading and unloading of marine products located at fishing ports, etc., and passengers getting on and off from small vessels etc. where the tidal level (water level) has a large tidal difference. This relates to a pontoon-type floating pier used for
〈従来の技術〉
従来の浮桟橋、とりわけ漁港等の岸壁に平行に設置され

切られた一方の甲板（船付き側）上に載荷される事が多
い。<Prior art> Conventional floating jetties, especially floating jetties installed parallel to the quay walls of fishing ports, are used to unload cargo from small vessels, etc. onto one deck (on the ship's side) separated by a longitudinal axis of symmetry. It is often loaded.
この様に長手対称軸で区切られた一方の甲板にのみ載荷
した時でも、安全上必要な乾げんの他、定められた傾斜
角以内に保たねばならない。Even when loading only on one deck separated by the longitudinal axis of symmetry, in addition to the necessary dryness for safety, the angle of inclination must be kept within the specified angle.

るか、浮桟橋全体の自重を重くし又は重心を下げて安全
性を保たねばならなかったので、経済性が悪かった。In such cases, in order to keep the inclination angle within the specified range, conventional methods have been to increase the number of mooring columns on the floating pier, increase the width of the floating pier, increase the weight of the entire floating pier, or lower the center of gravity. It was not economical because safety had to be maintained.

°以内にある事を特徴とする浮桟橋である。Means for Solving the Problems> The present invention provides a pontoon-type floating body with two mooring posts sandwiched between the longitudinal sides of the body, and a mooring tool for the floating body attached to each mooring post. The vertical interval shall be at least % of the transverse width of the pontoon-type floating body, and the inclination angle of the longitudinal symmetrical rotation axis due to eccentric loads, etc. shall be 10
It is a floating pier that is characterized by being located within 1°.

ツーン形状の長手対称軸にて区切られた船付き側の乾舷
高が低くなる様な傾斜現象を生じ易い。Loading and unloading from small vessels, etc. to floating jetties installed parallel to the quays of fishing ports etc. is usually carried out only on the lead side. Therefore, when cargo is unloaded onto the floating jetty , tends to cause a tilting phenomenon in which the freeboard height of the pontoon side, which is defined by the longitudinal symmetry axis of the pontoon, is lowered.
本発明は、この様な片寄り載荷時のポンツーン型浮桟橋
の傾斜をポンツーンの大きさや形状を変化させる事なく
、緩和させ利用者の安全を計るものである。The present invention aims to reduce the inclination of a pontoon type floating pier during such uneven loading without changing the size or shape of the pontoon, thereby ensuring the safety of users.

1) Two mooring columns are arranged on the longitudinal side so as to sandwich the floating body, and the mooring equipment for the floating body for each mooring column is arranged in two stages, upper and lower, with a sufficient gap between them to prevent uneven loading. It is possible to prevent the pontoon-type floating body from tilting at times, and to prevent the pontoon-type floating body from shaking due to waves or reflected waves generated by the rear quay.

あるが、係留柱についても同様の事が云える。It goes without saying that the pontoon-type floating body used in the present invention may be made of fiber-reinforced plastic, so-called FRP, copper, concrete, or a combination thereof, and the same can be said of the mooring columns.

隣接ポンツーン型浮体間に渡し板などをかける場合は、
片側へ寄せる事もよくある。Mooring equipment should include rubber rollers and synthetic resin-lined steel rollers that can be sufficiently gripped by mooring columns so that the pontoon-type floating body can easily move up and down according to the tidal difference, and there will be no shocking shaking due to waves, etc. etc., and it is preferable that the distance between the upper and lower sides is at least half the width of the pontoon type floating body. If the spacing is less than this, the load moment applied to the mooring equipment will be large, and mooring equipment that is significantly larger and stronger than the floating body will be required, which will impair economic efficiency. The attachment position of the mooring equipment is best on the longitudinal axis of symmetry on the shorter side of the pontoon type floating body in terms of stability, but it does not necessarily have to be on the axis of symmetry. Especially when installing spanboards between adjacent pontoon-type floating bodies,
It is often pushed to one side.
以下、本発明に係る実施例の一例を示す。An example of an embodiment according to the present invention will be shown below.

生じ、使用勝手がよくなった。As shown in Figure 2, when a load of 0.20 t/boat was applied to only one deck (on the ship's side) separated by the longitudinal axis of symmetry of this floating pier, an inclination of θ = 12.5° was achieved. However, it was found that the inclination was too large for safety reasons, so two mooring devices were used for each mooring column, one on top and one on top, as shown in Figure 3. The vertical interval was 120 cm, the lower mooring ring 4-1 was directly fixed to the side of the pontoon type floating body, and the upper mooring ring 4-2 was fixed to the upper part of the support base 8. With this improvement,
Even if the above-mentioned offset loading is carried out only on the side with the ship, the angle of inclination is around 1°, and the pontoon-type floating body hardly sways when waves in the bay are caused by wind waves or wake waves from a passing vessel. Ta. Two conventional mooring posts are used on one side. Compared to the method of fixing four mooring columns, there is no change in stability at all, and on the contrary, a space is created in which the span plate 9 can be installed between adjacent floating bodies, making it easier to use.
