Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a float for floating rafts equipped with mounting bolts to be attached to floating rafts such as aquaculture cages and floating piers.

(Prior Art) Conventionally, floats for floating rafts have been attached to the raft by simply being tied with a rope, or by being attached to a stainless steel band and bolted to the raft. A bolt was threaded through it so that the bolt could be attached to the raft.

(Problem that the invention aims to solve) However, in the case of a float that uses a rope to attach to a raft, the installation workability is poor and it is not possible to attach it firmly, and in the case of a float that uses a stainless steel band, the band itself is It was expensive and easy to install. In addition, in the case of a float that has bolts passed through it to attach it to the raft, the bolts simply pass through the float, and the bolts and float are not secured, causing looseness between them and the bolts. When tightened, the float easily deforms, making it difficult to securely install it.

(Means for Solving the Problems) In order to solve the above problems, the float for floating rafts of the present invention has a float body formed by covering the outer periphery of a solid synthetic resin foam with a fiber reinforced resin layer. The mounting bolt is buried with at least the tip of the threaded portion protruding outside, and a fixed resin layer of the same type as the resin content of the fiber reinforced resin layer is provided on the outer periphery of the bolt in this buried portion along the length direction of the bolt. At the same time, the fixed resin layer is continuously integrated with the fiber-reinforced resin layer.

(Example) The present invention will be described below with reference to the drawings.

In the drawings, reference numeral 1 denotes a float body, which is formed by covering the outer periphery of a solid synthetic resin foam 2, which is generally used as a float, with a fiber-reinforced resin layer 3 reinforced with fibers such as glass fiber. There is. The shape and size of the float main body 1 are not particularly limited as long as they are generally similar to general-purpose floats attached to floating rafts such as aquaculture cages and floating piers.

Numeral 4 is a mounting bolt for mounting the float main body 1 to a floating raft. The mounting bolt 4 is embedded and integrated in the float body 1 with at least the tip of the threaded portion protruding to the outside. The attachment of this bolt 4 and the float body 1 is performed, for example, in the first
As shown in the figure, in the buried portion of the bolt 4, a fixed resin layer 5 is provided on the outer periphery of the bolt 4 along the length direction of the bolt 4. This fixed resin layer 5 is formed from the same type of resin as the resin component of the fiber reinforced resin layer 3 of the float main body 1, and is continuously integrated with the fiber reinforced resin layer 3. The bolt 4 is generally embedded in the float body 1 in the vertical direction, with the tip of the threaded portion protruding upward from the float body 1. Further, the head of the bolt 4 may be buried in the float body 1 as shown in FIG. 1, FIG. 2, or FIG.
It may be protruded outward. Note that a plurality of mounting bolts 4 are embedded in the float body.

Next, to explain how to attach the float of the present invention to a raft, as shown in FIG. The nut 8 is screwed onto the holder and tightened.

(Effects of the invention) As detailed above, the float of the invention is provided with a fixed resin layer of the same type as the resin content of the fiber-reinforced resin layer along the length direction of the bolt on the outer periphery of the bolt embedded in the float body, and Since the fixed resin layer is continuously integrated with the fiber-reinforced resin layer on the outer periphery of the float body, the bolts and the float body can be integrated and firmly attached to the raft. Furthermore, even when the bolts are tightened, deformation or damage to the foam inside the float body can be prevented.

Furthermore, since the fixed resin layer is provided along the length of the bolt on the outer periphery of the bolt embedded in the float body, rusting can be suppressed even if the bolt is made of metal.

Claims (1)

[Scope of utility model registration request] A float body 1 is formed by covering the outer periphery of a solid synthetic resin foam 2 with a fiber-reinforced resin layer 3, and a mounting bolt 4 is embedded in the float body 1 with at least the tip of the threaded portion protruding outside. A fixed resin layer 5 of the same type as the fiber reinforced resin layer 3 is provided on the outer periphery of the bolt 4 in this buried portion along the length direction of the bolt 4, and the fixed resin layer 5 is not the same as the fiber reinforced resin layer 3. Continuously integrated floating raft float.
