Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to a floating body for a floating pier, and more particularly to a floating body for a floating pier with excellent durability.

(Conventional background) Since a floating body for a floating jetty needs to continue to give buoyancy to the floating jetty for a long period of time while being affected by waves, an ideal structure should have excellent durability.

And, as such a floating body for a floating pier, the conventional one is a block made of foam, which is covered with an outer wall such as cement mortar, and a mounting metal fitting embedded in the upper wall of the outer wall is used for the floating pier. It is configured to be mounted on the mounting frame of.

(Problems to be solved by the invention) By the way, in the case of a box-shaped outer wall, when the constituent wall portion of the outer wall has a large area, this wall is easily deformed by an external force in the vertical direction. In order to prevent this, it is necessary to increase the wall thickness, but then the floating body itself becomes heavy and the necessary freeboard cannot be secured. Especially when the external pressure is high, the tendency is high. Therefore, when the deformation exceeds the allowable range each time the external pressure is applied, cracks are generated in the wall portion, which also affects the durability.

Also, every time an external pressure is applied, an impact intermittently acts on the mounting portion between the mounting bracket and the mounting frame for the floating pier, and the outer wall of the concrete wall may be destroyed and the mounting bracket may drop off.

Therefore, an object of the present invention is to provide a floating body for a floating jetty which is excellent in durability without being deformed by an external pressure and the mounting metal fitting for the mounting frame for the floating jetty does not fall off.

(Means for Solving the Problem) The technical means taken to achieve the above-mentioned object are a block made of foam, and an outer wall covering the block,
A plurality of reinforcing bodies formed integrally with the constituent wall portion of the outer wall through the block, and a reinforcing body disposed in parallel to the lower constituent wall portion and the side wall of the outer wall. The gist of the invention is that it is composed of a U-shaped reinforcement that is embedded in the U-shaped reinforcement and a mounting portion that is provided above the U-shaped reinforcement and that is attached to the frame of the floating pier.

(Operation) (1) A plurality of reinforcing bodies which are integrally formed with the constituent wall portion of the outer wall by penetrating the block made of foam, and U embedded between the lower constituent wall portion of the outer wall and the left and right reinforcing bodies Cooperates with the character-shaped muscles to keep the outer wall in a box shape against deformation due to external pressure.

(2) The U-shaped streak receives the impact that acts on the mounting part of the floating jetty frame.

(Effects of the Invention) As described above, the present invention forms a rigid body that is not deformed by external pressure due to the function of the reinforcing body and the function of the embedded U-shaped muscle. Therefore, cracks due to external force do not repeatedly occur not only on the outer wall but also on the corners thereof, which prevents fatigue damage to the wall body, and even if foreign matter collides with the floating body, the outer wall is partially damaged. Since it does not lead to such a lack, it is possible to provide a floating body for a floating jetty having an ideal mechanical structure.

Moreover, since the impact of the external pressure acting on the mounting portion of the floating pier with the frame is received by the U-shaped streak continuously embedded in the internal reinforcing body formed integrally with the outer wall, the outer wall is not destroyed. In addition, it is possible to prevent the mounting portion from falling off and maintain a stable mounting state.

(Example) Next, the Example of this invention is described based on drawing.

1 to 3 show the first embodiment, and FIG. 4 shows the second embodiment.

In FIG. 1 and FIG. 2, A is a floating pier floating body, and a block 1 made of foam, an outer wall 2 enclosing the block 1, and a wall portion of the outer wall 2 penetrating the block 1 It has a plurality of reinforcing bodies 3 formed integrally with 2a ... And a U-shaped streak 4 embedded in the floating body A for floating piers.

The block 1 is formed of a foamable resin material into a rectangular parallelepiped shape having a vertical dimension of 1000 mm, a horizontal dimension of 2000 mm, and a height dimension of about 500 mm, and the outer peripheral surface is covered with an outer wall 2.

The outer wall 2 is formed by layering a material such as concrete mortar on the outer peripheral surface of the block 1, and has a thickness of
It is about 15 to 20 mm.

The outer wall 2 is for protecting the block 1 from an external pressure, and penetrates the block 1 to form a wall portion 2a of the outer wall 2 ...
Reinforcement 3 with multiple comrades connected to each other and U-shaped streak 4 described later
And give rigidity to external pressure.

The reinforcing body 3 is integrally formed by penetrating the block 1 across the upper constituent wall portion 2a of the outer wall 2 and the lower constituent wall portion 2a facing each other. A total of five positions close to the four corners are vertically extended across the upper constituent wall portion 2a and the lower constituent wall portion 2a.

The diameter of the reinforcing body 3 is arbitrary, but in the embodiment,
It is about 70-100 mm.

As shown in FIG. 2, the U-shaped streak 4 has its ridges 4a, 4a in the reinforcements 3, 3 juxtaposed in the short side direction of the floating pier floating body A.
In addition, the horizontal streak portion 4b between the vertical stirrup portions 4a and 4a is formed by the lower constituent wall portion 2
Each of them is embedded in a and the upper ends of the ridges 4a and 4a are located near the upper surface of the upper constituent wall 2a, and the screw 4c is engraved in the upper region thereof. Use floating pier B
The mounting portion 5 for the frame b is attached.

The mounting portion 5 is an insert nut having a biting protrusion 5a on the outer peripheral surface. The lower half of the nut hole 5b is screwed into the screw 4c so that the upper surface is flush with the upper surface of the upper constituent wall 2a. So as to be embedded in the upper constituent wall 2a.

As shown in FIG. 2, the floating body A for the floating pier of this embodiment has a shaft portion 6a of a mounting bolt 6 for mounting a frame b of the floating pier B,
It is screwed onto the upper half of the nut hole 5b and mounted on the lower surface of the floating pier B to give buoyancy to the floating pier B.

It is also possible to form the mounting portion 5 by projecting the upper ends of the ridge portions 4a, 4a of the U-shaped muscle 4 from the upper constituent wall portion 2a and engraving a screw in that portion. In this case, the projecting screw shaft portion may be inserted from the frame b and fixed with a nut to mount the frame b.

FIG. 4 shows an example in which a reinforcing layer 7 is applied to the outer wall 2 shown in the previous embodiment to improve impact resistance. The reinforcing layer 7 is
The planar body made by braiding the FRP reinforcement and the reinforcing bar in a planar shape is used to form the wall 2a ...
Is embedded so as to continuously surround the entire area, or a planar body made of steel fiber, synthetic resin fiber mesh, synthetic resin fiber chop, stainless steel mesh, etc. is similarly constructed. It is layered by embedding it so that the whole area is surrounded continuously.

Further, the above two kinds of sheet materials may be used in combination to further enhance the impact resistance.

In this embodiment, there is a feature that even if a strong external pressure is momentarily applied to each of the constituent wall portions 2a, cracks do not occur and the outer wall 2 does not drop out, it has shock resistance and is therefore a reliable floating pier. The floating body A can be provided.

In all the examples, the reinforcing body 3 is erected so as to connect the constituent wall portions 2a ... Composing each other and the adjacent constituent wall portions 2a. The shape retention may be further improved, and the reinforcing member 3 shown in the figure
Is not limited to the number and the directionality thereof.
