Next, the operation will be described. First, the main body 3 is positioned on the side of the form 1 on which concrete has been cast. Next, the winch 7 and the drive motor 10 are driven, and at the same time, the release agent is pressure-fed from the release agent pressure-feed tank 24. Then, the main body 3 travels in the direction of arrow A in FIG. 4, and the cleaning rope 20 circulates in the direction of arrow B in FIG. 6, to scrape off foreign matters such as mortar adhering to the outer peripheral surface side of the formwork 1. At the same time, the release agent is uniformly sprayed on the outer surface of the mold 1. In addition, although the above-mentioned automatic cleaning device of the concrete formwork does not impregnate the release agent into the cleaning rope 20, it may be configured to impregnate the cleaning rope 20 with the release agent. Alternatively, only the cleaning rope drive mechanism may be provided without providing the release agent supply mechanism. Further, the number of the cleaning ropes 20 may be one, three or more. Further, the above-mentioned automatic cleaning device for concrete formwork may be other than the above-mentioned example. For example, a rope type Keren device for a horseshoe-type form having a cleaning rope driving mechanism on each of the left and right described in Japanese Utility Model Publication No. 63-22236, and an automatic form-forming apparatus described in Japanese Patent Publication No. 60-46240. A cleaning device may be used.

[0004]

However, the conventional cleaning rope 20 used in the above-mentioned automatic cleaning apparatus for concrete formwork generally includes a wire rope or the like having a large tensile strength around a hardly stretchable core wire. It is formed by twisting a plurality of strands such as manila hemp (a cord formed by twisting several to several tens of yarns), and has high rigidity as a whole. On the other hand, the above-mentioned formwork 1 is slightly (about 1 to 2 mm) on its outer surface due to dimensional tolerance in production.
There are irregularities. For this reason, as shown in FIG. 8, when there is a concave portion (in FIG. 8, a flat portion or a curved portion with respect to the circumference or curved convex portion 101) 100 on the outer surface of the mold 1, The rigid cleaning rope 20 follows the convex portion on the outer surface of the mold 1 and cannot completely follow the concave portion 100. As a result, a gap is formed between the cleaning rope 20 and the concave portion 100 on the outer surface of the mold 1, and there is a problem that mortar or the like may be removed and left. In FIG. 8, the dimensions of the irregularities are shown large so that the irregularities on the outer surface of the mold 1 can be easily understood.

SUMMARY OF THE INVENTION An object of the present invention is to provide a cleaning rope for an automatic concrete formwork cleaning apparatus capable of reliably cleaning the outer surface of a formwork, particularly mortar or the like attached to a concave portion.

[0006]

According to the present invention, there is provided a core wire having a large tensile strength, and a plurality of strands twisted around the core wire, wherein the plurality of strands have different diameters. The surface of the cleaning rope is formed with irregularities.

[0007]

According to the present invention, even if the cleaning rope follows the projection on the outer surface of the mold, the projection on the surface of the cleaning rope completely follows the recess on the outer surface of the mold. As a result, it is possible to reliably clean the outer surface of the mold, particularly the mortar attached to the concave portion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a cleaning rope in an automatic concrete mold cleaning apparatus according to the present invention will be described below with reference to FIGS. In the figure, reference numeral 26 denotes a core wire, and the core wire 26 is made of a wire rope, a synthetic resin core material having a large rigidity, or the like, which has a large tensile strength and is difficult to elongate. 27 and 28 and 29 are strands.
And 28 and 29 are cords obtained by twisting together several to several tens of yarns, that is, yarns made of manila hemp or other synthetic resin fibers or natural fibers. The diameter of one of the three strands 27 is made larger than the diameter of the other two strands 28 and 29. The above-mentioned three strands 27 and 28 are wound around the above-mentioned core wire 26.
And 29 are twisted together to form a cleaning rope 30 having a continuous surface with irregularities.

In this embodiment, the cleaning rope 3 of the present invention is used.
As shown in FIG. 3, the protrusion 31 on the surface of the cleaning rope 30 of the present invention is
, Especially the recess 100 can be completely followed. As a result, it is possible to reliably clean the outer surface of the mold, in particular, the mortar or the like attached to the concave portion. In addition,
In FIG. 3, as in FIG. 8, the dimensions of the irregularities are shown large so that the irregularities on the outer surface of the mold 1 can be easily understood.

Although the cleaning rope 30 of the present invention in the above-described embodiment is composed of three strands 27, 28 and 29, it may be composed of two strands or four or more strands. . Further, the cleaning rope 30 of the present invention in the above-described embodiment is such that the diameter of one of the three strands 27, 28, 29 is larger than the diameter of the other two strands 28, 29. However, the number of strands whose diameter is different from that of the other strands is an arbitrary number between one or more and the number of strands less than one.

[0011]

As is apparent from the above description, the cleaning rope in the apparatus for automatically cleaning a concrete form according to the present invention comprises:
Since the diameters of the plurality of strands are made different from each other to form irregularities on the surface, it is possible that the convex portion on the surface of the cleaning rope of the present invention completely contacts the concave portion on the outer surface of the formwork. As a result, it is possible to reliably clean the outer surface of the mold, in particular, the mortar attached to the concave portion.
