Next, the rotating means 25 for rotating the bobbin 6 along the outer periphery of the concrete structure will be explained.

This rotating means 25 consists of a gear 26 for turning the bobbin 6, a chain 27, and the aforementioned limiters 1 to 7.

The motor 26 is attached to the back side of the support ring base plates 2,2 with an angle member 28, and its output shaft passes through the base plates 2.2 through 11 and projects onto the surface of the base plates 2,2. Attach Sub [] Kekera 1 to 9 to the protruding tip of this output shaft ()

The bobbin 6 can move freely according to the guiding direction of the guide groove 31, 33 by the bearing 32, 34 and the wheel 35, and can also rotate with respect to the support @8.

Attach this to the outer shell of the torque limiter 7 (connection plate 3)

A plurality of bobbins 6 and torque limiters 7 may be installed at arbitrary intervals on the chain 27 using connecting plates 3G.

In addition, as the reinforcing wire, conventionally known strand steel wire, 4! For example, a composite material made of epoxy resin reinforced with carbon fiber, glass fiber, etc. can be used for concrete, since it has high tensile strength and is lightweight. It is extremely effective to control the expansion and growth of cracks that occur during the crack period.

In the device configuration according to this embodiment, the guide ring base plate 3,

The end of the reinforcing dose v/A fiber 5 fed out from the bobbin 6 on the support ring base plates 2, 2 was placed on one of the external surfaces of the concrete body A. Stop winding as appropriate at J3<.

Next, I decided to drive both the motor 13J3 of the lifting mechanism 12 and the E-tar 26 of the rotating means 15 at a controlled rotational speed.
As the drive screw 1+t i /I is screwed at a predetermined speed, the support pedestal 16 of the rotating means 25 is moved along the support shaft 15, and the support ring base plate 2゜2 is moved along each guide rod 11.
The motor 26 gradually descends along the
By rotating one or two sprockets at a predetermined speed,
The bobbin 6 will be spun around the structure via the one-way 27.

For each of these integrated operations, that is, one downward rotation operation for the chain 27, the chain 27 is
The long fibers 5 of the girder bobbin 6 are spirally wound downward at a desired lead angle and winding angle around the structure Δ in 111j.

[5] As the chain 27 rotates, the bobbin 6 rotates while being given uniform rotational resistance by the torque limiter 7 and revolves around the concrete 1 to the groove structure.

As a result, the long fibers for reinforcement I11.5 can be

Continuously wound in one direction at predetermined intervals. l!
? Therefore, as a result, the structure was changed to the existing concrete 1.
It is possible to provide an earthquake-resistant reinforced structure by winding the long region M5, which is a reinforcing wire.

41 However, in the case of this actual sub-example configuration, the support ring base plate 2 is placed around the existing concrete structure △.
, 2 is reinforced by a predetermined interval pitch on the outer surface of the structure A, which controls the rotational speed of the chain 27 obtained from the lifting mechanism 12 and the rotating means 25. At the same time, the long fiber 5 is fed out from the bobbin 6 by the torque limiter 7, and by the tension limiter 11, the predetermined winding/manpower is set to I+? It will be done.

The so-called l-leak limiter 7 is a product widely used in the field of electric motor application dividers, etc., but there are individual differences in terms of content and action, and the one in this example is a clutch and spring limiter. It consists of a rotary input shaft and a link, and converts the input from the rotary input shaft into a constant torque rotational output.

In addition, in the above embodiments, the reinforced body was a cylindrical body and had concrete structures 1 to 8, but as shown in Fig. 4(a), when the concrete structure is a prismatic body, The arcuateness of the corners is 90", and the reinforcing wire to be wound is forced to change its angle rapidly, which is disadvantageous from the purpose of uniform winding of the reinforcing wire. In that case, J in the same figure:

In the same figure (b), the rotating body on the support ring base plate 2.2 is replaced with the chain 27 and a ring plate 27a is used. The ring plate 27a may be rotated by forming a south part on its outer periphery, and attaching 29 to the subrocket 1 of the turning motor 26 to rotate the ring plate 27a, but in this case, the outer periphery of the ring plate 27a may be left as it is. , rubber roller 29a instead of two sprockets
Alternatively, the ring tN27a may be rotated by pressure rotation of the rubber roller 29a. jJ compared to chain 27
8 is less likely to occur, and the installation work around the outer periphery of the structure A is somewhat easier.

(Effects) As detailed above, according to this invention, concrete 1
-In a device for winding reinforcing wire around the outer surface of a groove structure, the support 1/1 ring base plate and the guide ring base plate surrounding the target structure are installed. A positioning member is fitted into each of the upright guides so as to be able to move up and down, thereby maintaining the relative distance between the support ring base plate and the guide ring base plate. It is equipped with a rotary body mounted on the second plate so as to be freely movable, and a bobbin attached to the rotary body via a torque limiter. It also has a drive J screw shaft and a support shaft that are set up in parallel, and the operation Eh of the above-mentioned rotating body works together with the lifting mechanism that obtains lifting and lowering operations by controlling the rotation of the drive screw shaft. Since the bobbin can be moved spirally along the structure, the reinforcing wire is continuously wound at a predetermined tension and a pitch of 2 on the outer surface of the structure. - It is possible to wind the reinforcing wire around the external surface of the existing concrete structure in an orderly manner as planned by on-site work, which is often subject to various constraints due to the ship's construction site. It is extremely easy to carry out, and the bobbin is securely supported between the support ring base plate and the guide ring base plate, and the rotating body that drives the bobbin can be a V-bell or a chain, so it is easy to handle and transport. It is convenient to change the installation point of the 5 guide rollers according to the external shape of afforestation.

Furthermore, since the positioning member maintains the distance between support 1, j ring j; Sufficiently withstands lateral forces.

Te? By simply controlling the rotational speeds of the lowering motor 13 and the turning motor 26, the winding pitch interval of the reinforcing wire can be arbitrarily adjusted.
