Description

[0001]
[Technical field to which the invention belongs]
The present invention relates to a packing device and a packing unpacking device for a long fiber-reinforced plastic (FRP) reinforcing material such as a plate and a cable.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, as a method for reinforcing a concrete structure, there is an FRP tensioning method in which an FRP plate or cable, which is a continuous fiber reinforcing material, is mounted on a surface of an existing or new structure by introducing a prestress (tensile force).
[0003]
FIG. 13 shows an example in which the bridge is reinforced by the FRP tensioning method. In this example, a mode is shown in which prestress (tension) is introduced into the long FRP reinforcing member 100 and attached to the lower surface of the bridge girder.
[0004]
The long FRP reinforcing material 100 used in such an FRP tensioning method is obtained by impregnating a matrix resin into a reinforcing fiber sheet made of carbon fiber or the like, and curing the sheet. Shape or a rod shape (cable) (hereinafter, collectively referred to as “FRP plate”). Usually, a metal (for example, steel) or plastic fixing body 101 is fixed to both ends of the FRP plate 100 with an adhesive or the like, and the FRP plate 100 is in a state where tension is introduced by a tension device such as a jack. Then, it is fixed to the reinforced portion by the anchor bolt via the fixing body 101.
[0005]
When transporting a long thing exceeding 5 m, for example, with such an FRP plate 100, the FRP plate 100 is wound up in a circle independently without using a reel, or is wound up on a reel. There is a way to reduce the size.
[0006]
[Problems to be solved by the invention]
However, when the reel is not used, the weight increase is small and the packing volume is small, but when the fixing member 101 made of steel or the like is fixed to both ends of the FRP plate 100, packing is difficult, and the FRP plate is not transported during transportation. There is a risk of damage such as breakage of 100. Also, when using the FRP plate 100 as a reinforcing material for a bridge girder, it is necessary to extend the FRP plate 100 straight below the girder at the construction site. In order to extend, an operator needs to rotate the FRP plate 100 around one end with one end of the FRP plate 100 and extend it, which requires a large work space.
[0007]
On the other hand, when the FRP plate 100 is wound on a reel, the reel has a large diameter and requires a large space for transportation and storage. When the FRP plate 100 is used as a reinforcing material for a bridge girder in the same manner as described above, a device for rotating a reel is required when the FRP plate 100 is extended at a construction site. It was difficult to work with.
[0008]
For this reason, conventionally, when it is difficult to wind, pack, unpack, and transport without damaging the FRP plate 100, such as when there are fixing bodies at both ends, as shown in FIG. It was necessary to transport the FRP plate 100 with a long trailer or the like while the FRP plate 100 was extended.
[0009]
However, this has a problem that the transportation cost is high, and the length of the transportable FRP plate 100 is also limited, so that it is difficult to perform an effective reinforcing work according to the structure to be reinforced.
[0010]
Therefore, an object of the present invention is to make it possible to pack a long fiber-reinforced plastic reinforcing material in a small size, and to reduce the space required for unpacking work, and to place the long fiber-reinforced plastic reinforcing material at a desired position. An object of the present invention is to provide a packing device and a packing unpacking device for a long fiber reinforced plastic reinforcing material that can be easily extended.
[0011]
Another object of the present invention is to make it possible to reduce the weight and space of a long fiber-reinforced plastic reinforcing package, to reduce the storage and transportation costs of the package, and to improve the storage and transportation workability and efficiency. An object of the present invention is to provide a packing device and a packing unpacking device for a long fiber reinforced plastic reinforcing material which can be improved.
[0012]
Further, another object of the present invention is to provide a long fiber reinforced plastic reinforcing material having good workability without damage even when a fixing member is fixed to an end of the long fiber reinforced plastic reinforcing material. It is an object of the present invention to provide a packing device and a packing and unpacking device for a long fiber reinforced plastic reinforcing material capable of packing and unpacking.

[0046]
Example 2
Next, another embodiment of the packing and unpacking device according to the present invention will be described with reference to FIGS. 3 and 4. The basic configuration of the packing and unpacking device of the present embodiment is the same as that of the first embodiment, and the packaging device side positioning means and the turntable side positioning means are different. Accordingly, elements having the same or equivalent functions and configurations as those of the packing and unpacking apparatus of the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.
[0047]
As shown in FIGS. 3 and 4, in the packing and unpacking device A for the FRP plate 100 according to the present embodiment, the rotating shaft 32 protruding upward from the center of the lower table 30 of the turntable 2 is provided with an upper table. It is rotatably fitted to a rotation bearing 24 provided on the lower surface of the main body 21 so as to protrude downward. As a result, the center of the upper table 20 and the center of the lower table 30 are aligned by housing the rotating shaft 32 in the rotating bearing 24.
[0048]
In this embodiment, the turntable-side positioning means has a turntable-side protrusion 25 projecting upward from the upper surface of the upper table main body 21. In the illustrated example, the turntable-side protrusion 25 is a rod-shaped guide having a predetermined width and a predetermined length, which extends along four sides of the upper table main body 21 which is substantially square.
[0049]
On the other hand, the pallet 1 has a pallet-side projection 13 protruding downward from the lower surface of the pallet body 11 as a packing-side positioning means. The pallet-side projections 13 are provided at positions matching the turntable-side projections 25, and in the illustrated example, are continuous edges having a predetermined width and arranged along four sides of the substantially square pallet body 11. .
[0050]
The pallet-side projections 13 on the four sides each have a distance d1 (relative position) from the center of the pallet 1 to a distance d2 from the rotation center of the upper table 20 to each outer side wall 25a of the turntable-side projection 25 (relative position). And the turntable-side protrusion 25 and the pallet-side protrusion 13 are fitted through these side walls, whereby the center of the pallet 1 and the rotation center of the upper table 20 are aligned, The relative movement between the pallet 1 and the upper table 20 is prevented.
[0051]
Thus, similarly to the first embodiment, the pallet 1 can be easily rotated on the turntable 2 without being shifted from the center. Further, the pallet 1 does not fall off the turntable 2 when the FRP plate 100 is wound around the pallet 1 or pulled out from the pallet 1. Further, in the present embodiment, the relative movement between the pallet 1 and the upper table 20 is substantially completely prevented, and the pallet 1 does not slip on each other.
[0052]
The projections 13 and 25 are made of the same or different material as the pallet body 11 and the upper table body 21, respectively, and can be attached by an appropriate means such as bonding.
[0053]
Note that the positioning means on the package side and the positioning means on the turntable side are not limited to a mode in which the projections are adapted to each other. Either may be a through hole or a recess, and the other may be a protrusion. The relative position of the turntable-side positioning means with respect to the center of rotation of the turntable 2 and the relative position of the packaging-side positioning means with respect to the center of the pallet 1 match. The same effect can be obtained by providing these positioning means as described above.
[0054]
As described above, according to the configuration of the present embodiment, similarly to the first embodiment, the FRP plate 100 can be extremely easily packed and unpacked, and the FRP plate can be prevented from being damaged.

Further, as described above, a reinforcing means such as a rib or a pipe is provided to reinforce the flat pallet body 11 or the upper table 20, whereby the pallet is provided at least at the positions of the fixing portions 14a and 14b. If a sufficient gap is formed between the main body 11 and the upper table 20 main body 21 to accommodate the protruding portion 101p of the fixing body 101, these reinforcing means also function as separating members. Further, the projections provided as the pallet-side positioning means and / or the turntable-side positioning means described in the second embodiment allow the lower surface and the upper surface of the pallet main body 11 at least at the positions of the fixing portions 14a and 14b where the fixing body 101 is disposed. If a sufficient gap is formed between the table body 21 and the projection 101p of the fixing body 101, the projection serving as a positioning means also functions as a separation member.
