Description

[Detailed Description of the Invention] (a) Field of Industrial Application This invention assembles a large number of hollow cubes, which are plastic blow-molded products, and floats them on the water. It is a device relating to a connecting structure for assembling a floating jetty which constitutes the jetty.

(B) Conventional technology The assembled floating jetty by blow molding has already been put to practical use.
It is used for various purposes as described above, it is lightweight and easy to handle, the structure of area and shape can be freely changed according to the application, it is colorful, excellent in durability, strength, buoyancy, etc. However, the conventional structure for assembling a floating jetty is mainly shown in Fig. 2 where each corner of the plastic blow molding cube (1) (hereinafter referred to as "float") is used. An assembling protrusion (14) having a through hole is provided in the portion, and these protrusions (1) of each float (1) are provided.
4) were piled up and assembled by an assembly member (4) such as a pin (41) with a locking projection or a bolt (42) with a nut (43).

(C) Problems to be Solved by the Invention The conventional assembly floating jetty by blow molding is as described above, and the protrusions (1) provided at the four corners of each float (1) are as described above.
4) are stacked and each through-hole is connected by fixing with an assembly member (4), and therefore, in order to flatten the surface of the assembled pier, each corner of each float (1) is It is necessary to check the height of the protrusions (14) at the time of assembling so that the work is complicated, and there is only one place when a failure occurs in the float or the assembly. There was a problem that not only dismantling but also dismantling the surrounding area and requiring reassembly. The present invention has succeeded in solving the above problems and providing a floating jetty that can be extremely easily repaired by dismantling or replacing only the lowest unit where a failure has occurred. Is.

(D) Means for Solving the Problems and Its Actions Below, the connection structure of the hollow molded floating pier according to the present invention will be described.
A specific description will be given based on the drawings showing an example of the embodiment. FIG. 1 is a plan view of four blow-molded cubic floats before assembly in the case of connection, and FIG. 1 (a) is a plan view thereof, but a projection provided at a corner of each float (1) Plate part (1
1), a connecting member (2) having a plurality of protrusions (21) which fit into the through holes (12) formed therein and having a female screw penetration (22) in the center thereof, and FIG. As shown in (c) and (d), the connecting member (2) is screwed through the protruding plate (11), and at the same time, connected to the through hole (12) of the protruding plate (11). The floating pier connection structure is composed of a tightening member (3) having a male screw (31) screwed to the female screw (22) for fitting the member protrusion (21). That is, when assembling and connecting, as shown in Fig. 1 (a) (plan view) and Fig. 1 (b) (bottom view), a plurality of cube floats (1) are contact-combined at respective corners (Fig. It is also possible to show four assembling, or change the shape of the cube to make three or more assembling.)
The connecting member (2) is inserted through the gap between the plate-like protrusions (11) of each float as shown in FIG. (A), and each connecting member protrusion (21) protrudes as shown in FIG. 1 (b). Plate part (1
1) Just below each through hole (12), the locking projection (1
3) It is rotated until it is locked by Fig. 1 (c),
As shown in (d), the connecting projection (21) of the connecting member (2) is attached to the through hole (1) of the float by the tightening member (3).
It can be tightened by screwing until it is completely fitted to 2). That is, a plurality of floats can be simultaneously connected under the same condition, and disassembling, repairing, etc. can be carried out very easily and simply by making the height of the surface of the tightening member when tightening flush with the float surface. . Since the peripheral portion of the jetty is mainly connected to only two floats, the appearance of the coupling strength is similar to that of the conventional jetty, such as a bolt (41) and a nut (42) shown in FIG. 2 (b). It is also possible to use a connector (4) or the like.

(E) Effect of the Invention According to this invention, since the positions and heights of the connecting portions of the float are all constant, when replacing the float or an assembly portion due to a failure or the like, the float around the float can be replaced to some extent as in the conventional case. There is no complexity of disassembling and reassembling, and it is extremely easy by partially dismantling and replacing only one place,
This makes it possible to easily repair or the like.
