By connecting both ends to the device main body 3 and operating the winch 12, the device main body 3 can be moved along the beam 2.

A drive motor 15 is mounted on the horizontal member 4 of the apparatus main body 3, and a drive sprocket 28 is provided on the rotational shaft of the drive motor 15, and a driven sprocket 29 is supported at the upper end of the first vertical member 5. The chain 16 is wound around the drive sprocket 28 and the drive sprocket 28. A first fixed position pulley 17 and a second
The fixed position pulley 18 is rotatably supported on the first vertical member 5, the second vertical member 6, and the auxiliary vertical member 7, and the first movable pulley 19 and the second movable pulley 20 are rotatably supported on the vertical members 5, 6. . By linking the driven sprocket with the first fixed position pulley 17 and the second fixed position pulley 18 and driving the drive motor 15, the first fixed position pulley 17 and the second fixed position pulley 18 are connected.
The fixed position pulley 18 can be rotated. The device main body 3 is provided with two threaded rods 22, and the threaded rods 22 and the rotating shafts 23 of the first movable pulley 19 and the second movable pulley 20 are linked via a tension spring 24, and the first movement The pulley 19 and the second movable pulley 20 are always urged downward (in the direction of arrow C). A guide roller 25 is rotatably attached to the upper ends of the first vertical member 5 and the second vertical member 6 of the apparatus main body 3.

A ring frame 26 is fixed to the top ends of the first vertical member 5 and the second vertical member 6 of the device main body 3. This ring frame 26 has a V-shaped part at the upper part and a flat part at the lower part, and has a shape that is slightly larger than the outer circumferential shape of the demolded formwork 1. Four guide rollers 27 are provided on the inner peripheral side of the ring frame 26 at approximately equal intervals and are rotatable, and two sets of corner processing mechanisms 30 are provided on the lower flat portion. The corner processing mechanism 30 includes a first pull-out roller 31 and a second pull-out roller 32, and a first feed roller 33 and a second feed roller 34. The first fixed position pulley 1
7. First moving pulley 19, two sets of corner treatment mechanisms 3
0 first pull-out roller 31 and first feed roller 3
3, the second fixed position pulley 18, the second movable pulley 20, the second pull-out roller 32 and the second feed roller 34 of the two sets of corner processing mechanisms 30, and a first cleaning rope 35 and a second cleaning rope. At the same time, the first cleaning rope 35 and the second cleaning rope 36 are stretched endlessly so as to surround the outer surface of the formwork 1.

A mold release agent supply pipe 37 is fixed to the surface of the ring frame 26 on the opposite side to the drive motor 15 side, following the shape of the ring frame 26, and a nozzle 38 is installed on the inner peripheral side of the mold release agent supply pipe 37. Provide many at equal intervals. A high-pressure hose 4 connects this mold release agent supply pipe 37 and a mold release agent pressure-feeding tank 40 installed in the tunnel 39.
Connect by 1.

Next, the operation will be explained. First, the automatic cleaning device is positioned on the side of the formwork 1 where concrete has been poured. Next, the winch 12 and drive motor 15 are driven, and at the same time, the mold release agent is pumped from the mold release agent pressure feeding tank 40. Then, the main body 3 of the apparatus travels in the direction of the arrow A in FIG. 1, and the first cleaning rope 35 and the second cleaning rope 36 circulate in the direction of the arrow B in FIG. At the same time, the mold release agent is uniformly sprayed onto the outer circumferential surface of the mold 1 from the nozzle 38 of the mold release agent supply pipe 37.

Note that the automatic concrete formwork cleaning device described above is designed to prevent the cleaning ropes 35 and 36 from getting wet with the mold release agent.
5 and 36 may be impregnated with a mold release agent, or a structure may be provided in which only a cleaning rope drive mechanism is provided without providing a mold release agent supply mechanism. Further, the number of cleaning ropes may be one, three, four, etc.

However, the cleaning ropes 35 and 36 in the above-mentioned automatic cleaning device for concrete formwork are made by covering a core metal material with a coating material, and have a certain degree of rigidity so as to be able to withstand tensile strength. . Therefore, in the case of a metal form, a polygonal formwork, or a formwork with a flat part, the cleaning rope 3 is used as shown in FIG.
5 and 36 cannot perfectly imitate the shape of the outer surface of the formwork 1 (metal form) due to their rigidity. As a result, a gap may be created between the cleaning ropes 35, 36 and the intermediate portion of the flat portion 100 of the formwork 1, and mortar or the like may be removed and left behind.

In view of the above-mentioned points, the present invention aims to provide a cleaning rope that can reliably remove mortar and the like adhering to formwork.

The present invention is characterized in that a plurality of protrusions are provided at various locations. Hereinafter, two examples of cleaning ropes in an automatic cleaning device for concrete formwork according to the present invention will be described with reference to FIGS. 5 to 8.

The cleaning rope 50 in this embodiment has a core material 51 made of wire or the like covered with a covering material 52 made of manila hemp or the like, and provided with a plurality of protrusions 53 in some places. As shown in FIGS. 5 and 6, this expanded protrusion 53 includes a expanded protrusion 54 provided on the core metal material 51,
It is formed by covering the core metal material 51 with the covering material 52, or by covering the core metal material 51 with the covering material 52 and covering the various parts 55 two or three times.

Since the cleaning rope of the present invention in this embodiment has the above-described configuration, as shown in FIG.
Even if there is a gap between the cleaning rope 50 and
Since the swollen portion 53 comes into pressure contact with the flat portion 100 of the formwork 1, mortar and the like adhering to that portion can be reliably removed. Further, since the cleaning rope 50 comes into pressure contact with the formwork 1 at its swollen protrusion 53, the area of pressure contact between the cleaning rope 50 and the formwork 1 is reduced compared to the conventional cleaning rope 50. Contact resistance (frictional force) with the frame 1 increases. As a result, the force of the cleaning rope 50 to remove mortar and the like is increased, and the effect of removing mortar and the like is reliably and improved. Further, the cleaning rope of the present invention in this embodiment has a core material 51 such as a wire coated with a covering material 52 such as manila hemp, so that it can sufficiently withstand tensile strength.

In addition, in the above-mentioned embodiment, the cleaning rope 50
Manila hemp is used for the covering material 52, but it may be made of other fibers (synthetic resin or natural), or may be made of synthetic resin in the form of a tube. On the other hand, as the core material 51, a synthetic resin core material having high rigidity (that is, strong in tensile strength and difficult to stretch) may be used in addition to the wire rope.

FIG. 8 is a partially sectional view showing another modification of the cleaning rope of the present invention.

In the cleaning rope 60 of this example, a required number of spherical members 62 are fixed to a core material 61 at various locations to form swollen protrusions 63, or the core material 61 is swollen spherically at locations to form swollen protrusions 63. It was formed. In addition,
The core member 61 may be made of wire rope or synthetic resin, while the spherical member 62 may be made of synthetic resin or fiber. In particular, the material is not limited.

In addition to the above-mentioned protrusion, for example, a spring, a washer, a synthetic resin sleeve, an aluminum sleeve, a brush, etc. may be used as the protrusion.

As is clear from the above examples, the cleaning rope of the present invention has a plurality of protrusions at various places, so there is a gap between the flat part of the formwork and the cleaning rope. Also, the swollen protrusion of the cleaning rope can press against the flat part of the formwork. Therefore, mortar and the like can be reliably removed from the flat portions of the formwork. Further, since the formwork and the cleaning rope are in point contact at the swollen portion, the frictional force between the formwork and the cleaning rope is increased, and the effect of removing mortar and the like is reliably and improved.

Note that, as a matter of course, the cleaning rope of the present invention is not limited to the above-mentioned embodiments.
