When the fastening means moves a distance corresponding to the stroke of the jack, the operation of the jack is stopped, and the fastening means is operated to fasten the columnar structural member, thereby fixing the fastening means. Releasing the fastening of the holding means after fixing the fastening means.

The ring is moved with respect to the tightening means,
During this movement, the rotating ring can be rotated to wind the striated body around the columnar structural member. And jack 1
When the stroke, that is, the movement of the maximum extension or contraction is completed, the holding means is operated and fixed to the columnar structural member,
Since it is possible to release the fixing of the fastening means and move the fastening means and prepare for the next operation, equipment other than the winding device such as a lifting device is unnecessary, even if there is no space for disposing the lifting device. And a method of winding the striatum.

Since a ring is arranged around the columnar structural member and the rotating ring is supported by this ring, the cross section of the columnar structural member is not only a quadrangle but also a circular or elliptical shape, and both ends are arc-shaped. In addition, even if these arcs are connected by a straight line, the filament can be wound as long as the columnar structural member can be located in the ring and the rotating ring. Therefore, the pillar-shaped structural member on which the striatum can be wound according to the present invention is a pillar of a building, a pillar of an elevated road or an elevated railway, or a pier of a bridge. Is small, and a striated body can be wound around such a columnar structural member to reinforce the columnar structural member.

[0008] The present invention also relates to a first to fourth four side faces arranged so that a lower portion of a pillar having a rectangular cross section is spaced from a sleeve wall having a height lower than the height of the pillar. It is a method of winding a striatum around a pillar. First, the column can be tightened, and a plurality of tightening means that can release the tightening, the column can be tightened, and a plurality of holding means that can release the tightening, and the wire can be hooked, and A frame having first to fourth lockable first to fourth locking means, wherein the locking means are arranged such that the four locking means are respectively located at the four corners of the pillar, and enter the clearance; A frame capable of supporting the winding means so that the winding means which has wound the striated body can rotate along the ring, wherein the fastening means is positioned relative to the ring. The fastening means is connected via a jack which can be moved in the axial direction of the pillar so as to be movable, and the frame is supported so that the frame hangs down. The ring, the ring is arranged to surround the pillar above the sleeve wall. After the placement of the ring, the tightening means is actuated to tighten the column, thereby fixing the tightening means and fixing the end of the striatum in a predetermined position on the first side of the column. The filament is hooked on the first locking means located near the fixed end of the filament in the direction in which the filament is wound around the column, and the filament is wound in the direction in which the filament is wound around the column. First
The winding means is guided to a portion opposed to the second side surface adjacent to the side surface of, and a tensile force is applied to the striatum. The ring is moved by a predetermined distance in the axial direction of the column by operating the jack, and the striatum is gripped by the first locking means. Hereinafter, sequentially hooking the striated body on another locking means, guiding the winding means to a portion facing another side surface, applying a pulling force to the striated body, moving the ring, and grasping the striated body. repeat.

Usually, there is no gap between the pillar and the sleeve wall, so a gap is first created. The clearance may be large enough to accommodate the ring frame. A ring is placed around the post above the sleeve wall, for example by hooking the striated body on the locking means at the corner of the first side and guiding the winding means to a position opposite the second side. Apply tension to the striated body. Without the locking means to hook the striatum, the striatum comes into contact with the corner of the column and generates a large frictional force,
Although sufficient tensile force cannot be introduced into the striatum, in the present invention, the striatum is hooked on the locking means and separated from the corner, so that the striatum is subjected to a sufficient tensile force. In this state, the ring is moved, and then the striated body is gripped by the locking means. Therefore, the striated body can be wound around the columnar structural member while a tensile force is applied to the striated body. In this manner, the striated body can be wound on the pillar having a clearance between the sleeve wall and the gap in which the ring of the winding device cannot enter, with the necessary tensile force applied.

The present invention is also an apparatus for winding a striated body around a columnar structural member. In this device, a ring capable of releasing the surroundings of the columnar structural member is disposed so as to surround the columnar structural member. The columnar member can be tightened, and
A plurality of retaining means capable of releasing the tightening are attached to the ring. A plurality of fastening means capable of fastening the columnar structural member, and capable of releasing the fastening, are connected to the ring by extendable jacks, respectively,
It is arranged to be relatively movable with respect to the ring. A rotating ring is supported for rotation along the ring. A winding means for the filament is supported by the rotating ring. This winding means enables the filament to be pulled out with a braking force applied to the filament.

Since the ring and the fastening means are connected by a jack and are relatively movable and the holding means is attached to the ring, the fastening means is fixed and the holding means is fixed when the ring is to be moved. By releasing the clamping means and releasing the fastening of the fastening means when the fastening means is to be displaced and fixing the holding means, the winding device can be moved along the columnar structural member. In this manner, the winding device can perform the winding of the striated body and the movement of itself. Therefore, even when there is a narrow space around the columnar structural member where the lifting device cannot enter, the striated body can be wound around the columnar structural member as long as the winding device can enter the space.

After the holding means 26 is fixed, the tightening of the tightening means 24 is released, and the jack 32 is operated to move the tightening means 24 in the moving direction of the ring 22. In the embodiment shown, since the ring 22 has been moved upward, the tightening means 24 is also moved upward.

When the fastening means 24 has moved a distance corresponding to the stroke of the jack 32, the operation of the jack 32 is stopped, and the fastening means 24 is operated to activate the columnar structural member 20.
, Thereby fixing the fastening means to the columnar structural member 20. In this state, the fastening means 24
And the ring 22 have the positional relationship shown in FIG.

After fixing the fastening means 24, the fastening of the holding means 26 is released. As a result, the ring 22 becomes movable again. Accordingly, the operation of the jack 32 to move the ring 22 in the axial direction of the columnar structural member 20 is repeated, so that the tightening means 24 is fixed, and then the tightening of the holding means 26 is released. Can be wound over substantially the entire length of the wire.

In the embodiment shown in FIGS. 1 to 5, the columnar structural member 20 is a rectangular column, and the ring 22 is moved by extending the jack 32 from the reduced state. Alternatively, as shown in FIGS. 6 to 8, the striated body 28 can be wound around a circular columnar structural member 40. The jack 42 is operated to contract from the extended state (FIG. 7), and when the distance ring 22 corresponding to the stroke of the jack 42 moves, the jack 42 contracts (FIG. 8). Further, in the embodiment of FIGS. 1 to 5, the winding means 30 is located above the ring 22, but in the embodiment of FIGS.
It is located below.

In the embodiment of FIGS. 6 to 8, the jack 4
2 is operated to contract from the extended state, and since the winding means 30 is located below the ring, the columnar structural member 40 is located at the base of the columnar structural member 40 rising from the floor 44. A fixture 34 can be attached. As a result, the striated body 28 is wound from the base of the columnar structural member 40.

As shown in FIG. 9 showing the front state, FIG. 10 showing the enlarged state of the locking means, and FIG. 11 showing the plane state, the lower part of the column 50 having a rectangular cross section is The striated body 2 is attached to a pillar 50 having first to fourth four side surfaces 54, 56, 58, 60 arranged so as to have a clearance from a sleeve wall 52 having a height lower than the height of the pillar 50.
8 is wound. Usually, since the pillar 50 and the sleeve wall 52 are joined, in order to reinforce the pillar 50 by practicing the present invention, there is a gap 5 between the pillar 50 and the sleeve wall 52 in advance.
Make one. The four sides of the pillar 50 are the first side 5
Although FIG. 11 shows the second, third, and fourth counterclockwise directions in FIG. 11 for convenience of explanation, the winding of the filament may be performed from any side and in any direction.

First, the ring 62 is placed above the sleeve wall 52 by the column 5.
The ring 62 is arranged so as to surround 0. Ring 62
Is formed by attaching a frame 64 to the same structure as the ring 22. That is, the ring 62 is
A plurality of tightening means 24 capable of tightening 0 and releasing the tightening, a plurality of holding means 26 capable of tightening the column 50 and releasing the tightening, and the frame 6
4 is provided. The frame 64 is capable of entering the gap 51, and the first to fourth four locking means 66, 68, 70,
72. The four locking means are arranged so as to correspond to the four corners of the pillar 50, respectively.
The locking means 66 is attached to the sleeve wall 52 in order to avoid interference with the sleeve wall 52, but the corner portion is used including this position. The ring 62 supports the winding means 30 so that the winding means 30 that has wound the striated body 28 can rotate along the ring 62, and the tightening means 24 supports the ring 62.
The fastening means 24 is connected via a jack 42 which can be expanded and contracted in the axial direction of the column 50 so as to be able to move relative to the frame 50.
4 is supported.

After the placement of the ring 62, the fastening means 24 is actuated to tighten the post 50, thereby fixing the fastening means 24 to the post 50. Then, the end of the striated body 28 is fixed at a predetermined position on the first side surface 54 of the pillar.

The filament is hooked on the first locking means 66 located close to the fixed end of the filament 28 in the counterclockwise direction, which is the direction in which the filament 28 is wound around the column 50.
The reason that the striated body 28 is hooked on the first locking means 66 is as follows.
Performed by workers. Then, the winding means 30 is guided to a portion facing the second side surface 56 adjacent to the first side surface 54 in the direction in which the striated body is wound around the column 50, and applies a pulling force to the striated body.

The ring 62 is moved by a predetermined distance in the axial direction of the column 50 by operating the jack 42 so as to contract from the extended state, and the first locking means 66 grips the filament 28. Here, the predetermined distance is a pitch at which the filament 28 should be wound. Since the striated body 28 is hooked on the first locking means 66 before the movement, the ring 62 moves without any trouble. During this movement, the striated body 28 is subjected to a pulling force, so that the striated body 28 is gripped by the first locking means 66 so that the first locking means 6
The portion of the striated body located between 6 and the fixed end is held in a state where a tensile force is applied.

The filament 28 is hooked on the second locking means 68 which is located close to the first locking means 66 in the direction in which the filament 28 is wound around the column 50. Then, in the direction in which the striated body 28 is wound around the column 50, the second side surface 5
The winding means 30 is guided to a portion opposed to the third side surface 58 adjacent to 6 and applies a pulling force to the striatum 28.

The gripping of the striated body by the first locking means 66 is released while a tensile force is applied to the striated body 28. Since the striated body 28 is under tension, even if the gripping by the first locking means 66 is released, the winding means 3
Substantially the same tensile force acts on the portion of the striatum from zero to the fixed end.

By operating the jack 42, the ring 62 is
0 in the axial direction, and the second locking means 68
Grips the striatum. Here, the holding of the striated body 28 by the first locking means 66 is unnecessary, and the holding by the second locking means 68 alone is sufficient. Pillar 50 first
Of the striated body along the side surface 54 of the striated body 28
Is passed through the corners of the pillar, so that the striated body 28 is not loosened by the gripping by the second locking means 68.

The striated body is hooked on the third locking means 70 located close to the second locking means 68 in the direction in which the striated body 28 is wound around the column 50. Then, in the direction in which the striated body 28 is wound around the column 50, the third side surface 5 is formed.
The winding means 30 is guided to a portion opposed to the fourth side surface 60 adjacent to 8 and applies a pulling force to the striated body 28.

The gripping of the striated body by the second locking means 68 is released while a tensile force is applied to the striated body 28. Since the striated body 28 is under tension, even if the gripping by the second locking means 68 is released, the winding means 3
Substantially the same tensile force acts on the portion of the striatum from zero to the fixed end.

By operating the jack 42, the ring 62 is
The third locking means 70
Grips the striatum. Here, the holding of the striated body 28 by the first locking means 66 and the second locking means 68 is unnecessary, and the holding by the third locking means 70 alone is sufficient. The portion of the striatum along the first side 54 of the column 50 and the portion of the striatum along the second side 56 are maintained in a sufficiently tensioned state; Since the striated body 28 has passed through the two corners of the column, the striated body 2 is gripped by the third locking means 70.
8 does not loosen.

The filament 28 is hooked on the fourth locking means 72 located close to the third locking means 70 in the direction in which the filament 28 is wound around the column 50. Then, the fourth side surface 6 in the direction in which the striated body 28 is wound around the column 50.
The winding means 30 is guided to a portion opposed to the first side surface 54 adjacent to the zero and applies a pulling force to the striated body 28.

The gripping of the striated body by the third locking means 70 is released while a tensile force is applied to the striated body 28. Since the striated body 28 is under tension, even if the gripping by the third locking means 70 is released, the winding means 3
Substantially the same tensile force acts on the portion of the striatum from zero to the fixed end.

By operating the jack 42, the ring 62 is
0 for a predetermined distance in the axial direction, and the fourth locking means 72
Grips the striatum. Here, the first locking means 66, the second locking means 68, and the third locking means 70
It is not necessary to grip the striated body 28 by, and it is sufficient to hold the striated body 28 only by the fourth locking means 72. The portion of the striatum along the first side 54 of the column 50, the portion of the striatum along the second side 56, and the portion of the striatum along the third side 58 are sufficient. Is held in a state where it is subjected to a tensile force, and since the striated body 28 passes through the three corners of the column, the striated body 28 is loosened by the gripping by the fourth locking means 72. Does not occur.

The filament is hooked on the first locking means 66 located close to the fourth locking means 72 in the direction in which the filament 28 is wound around the pillar. Then, the winding means 30 is provided at a position facing the second side surface 56 adjacent to the first side surface 54 in the direction in which the striated body 28 is wound around the column 50.
And a tensile force is applied to the striatum 28.

The gripping of the striated body by the fourth locking means 72 is released while a tensile force is applied to the striated body 28. Here, the striated body 28 is wound around the pillar 50 one round. Then, the jack 42 is operated to move the ring 62 a predetermined distance in the axial direction of the column 50, and the first locking means 66 grips the striated body 28. By repetition of releasing the grip of the striated body, the striated body 28 can be wound over substantially the entire length of the column 50.

The jack 42 is operated to move the ring 62 to the pillar 5.
The first locking means 66 moves a predetermined distance in the axial direction of the first locking means 66.
When the ring 62 moves a distance corresponding to the stroke of the jack 42 during the operation from the gripping of the filament 28 by the fourth locking means 72 to the release of the grip of the filament 28 by the fourth locking means 72. Is stopped, and the winding means 30 is held at that position. Thereafter, the holding means 26 is actuated to tighten the column 50, thereby fixing the holding means 26,
After fixing, the tightening of the tightening means 24 is released,
By operating the jack 42, the fastening means 24 is
When the fastening means 24 has moved a distance corresponding to the stroke of the jack 42, the operation of the jack 42 is stopped, and the fastening means 24 is operated to tighten the column 50, whereby the fastening means 24 is moved.
After fixing the fastening means 24, the operation of releasing the fastening of the holding means 26 is performed.
