Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a floating jetty arranged in a river mouth, a coast, a waterway, a storage area, etc., and a floating jetty component member constituting the floating jetty,

[0002]

[Prior art]

 As shown in FIG. 6, a floating jetty of this type generally includes a floating body portion 1 made of a synthetic resin called a pontoon and a rigid jetty frame portion 2 arranged on the floating body portion 1. Each member has a length of 10 to 12 m and a width of about 2 m.

Although the above floating pier can be used alone, a plurality of combined floating piers can be formed into a desired shape. However, in the above-mentioned conventional one, since the plane dimension is large, it is difficult to transport and the degree of freedom of layout when forming a bridge is small.

[0004]

[Problems to be solved by the device]

 Therefore, it is an object of the present invention to provide a floating pier component member and a floating pier that are easy to transport and have a large degree of freedom in layout when forming a bridge.

[0005]

[Means for Solving the Problems]

 The present invention is a floating pier constituent member, and is composed of a short floating body portion 1 and a short pier frame portion 2 arranged on the floating body portion 1 and having a rectangular planar shape. The joint portion 3 is provided on at least two of the two side surfaces 20.

Another aspect of the invention is a floating pier, wherein the floating pier constituting members are formed so that the joint portions 3 and 3 are joined to each other. Further, the floating pier of another invention is composed of at least two floating pier constituting members and a pier frame 2 joined between the floating pier constituting members via joints 3 and 3.

[0007]

[Action]

 This device has the following effects. In the floating pier of the present invention, the floating body 1 and the pier frame 2 can be transported to the site as a short integrated body (floating pier constituent member), which facilitates transportation. Further, both the floating body portion 1 and the pier frame portion 2 are short, and the joint portions 3 are provided on at least two of the four side surfaces 20 of the pier frame 2, so that the layout for forming the bridge can be improved. The degree of freedom will be great.

Further, when the floating pier is composed of at least two floating pier constituting members and the pier frame 2 joined between the floating pier constituting members via the joints 3 and 3, the number of floating bodies Can be changed as desired.

[0009]

【Example】

 The configuration of the present invention will be described below with reference to the drawings shown as examples. In this embodiment, as shown in FIG. 1, a floating body 1 (having a length of about 1.7 m) and a flat rectangular pier frame portion 2 (having a length of about 2 m) bolted onto the floating body 1 are used. A short floating pier component is constructed from the above and the floating pier is formed by connecting a plurality of these floating pier components.

As shown in FIG. 1, the pier frame portion 2 is composed of a rectangular frame body made of channel type steel (which may be made of aluminum) and has a certain load bearing strength. As shown in FIG. 3, each of the four side surfaces 20 of the pier frame 2 is provided with a bolting portion 30 (corresponding to the joint portion 3 in the column of means), and the pier frame portions 2 and 2 are provided. It is designed to be detachably connectable. If the load bearing strength is not required so much, the pier frame portion 2 may be made of synthetic resin. Further, the bolt fastening portions 30 provided on the pier frame 2 may be only two or three side surfaces 20 out of the four side surfaces 20.

The floating body 1 is made of synthetic resin, and as shown in FIGS. 1 and 2, the left and right sand storage chambers 10 for storing the sand S functioning as a weight, and the sand storage chambers 10, 10 described above. It is composed of a resin storage chamber 11 in which the foamed resin material H is stored between each other, and by changing the amount of the sand S in the sand storage chamber 10, the drinking water L can be changed.

As shown in FIG. 3, the pier frame portions 2 and 2 are connected to each other by bolting them using the bolt retaining portions 30 on both sides. Since the floating pier of this embodiment is constructed as described above, the floating pier constituting members having a plane dimension of about 2 m × 2 m are transported, and can be easily transported to the site. The pier frame sections 2 are both short, about 2 m, and bolt side portions 30 are provided on the four side faces 20 of the pier frame 2 so that they can be connected to each other in the left-right and front-rear directions. The degree of freedom in layout when forming a bridge is extremely large.

In the above embodiment, the bolted portions 30, 30 of the pier frame portions 2, 2 are bolted to each other. However, the invention is not limited to this. Good. Further, in the above-mentioned embodiment, the floating body 1 and the pier frame portion 2 are configured separately, but the present invention is not limited to this, and as shown in FIG. You may make it formed in.

Further, in the above embodiment, the floating pier is configured by only the floating pier components, but the present invention is not limited to this, and one floating pier component may be provided between the floating pier components, as shown in FIG. Alternatively, a floating jetty may be configured by interposing a plurality of jetty frames 2 (without the floating body portion 1).

[0015]

[Effect of device]

 Since the present invention has the configuration as described above, it has the following effects. From the contents described in the action column, it was possible to provide a floating pier component member and a floating pier that are easy to transport and have a high degree of freedom in layout when forming a bridge.
