【産業上の利用分野】本発明は、コンクリート構造物等
の破壊に際するコンクリート、石材等のワイヤーソーに
よる切断加工方法に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for cutting concrete, stone or the like with a wire saw when destroying a concrete structure or the like.

ーソーは広く知られている。2. Description of the Related Art A wire saw is widely known in which abrasive members (beads) in which ultra-hard abrasive particles are embedded in a metal matrix are fixedly arranged at predetermined intervals in the longitudinal direction of a wire rope.

によりエンドレス化を行なう。A case where such a wire saw is used for cutting a concrete wall will be described with reference to FIG. In order to cut the concrete wall 11, a wall through hole 12 is made in the wall by a core drill. Both ends of the wire saw 13 are passed through the through holes 12 to guide the guide roller 1 of the drive side device.
Although not shown in the drawings, both ends of the wire rope 16 of the wire saw 13 before and after engaging with the drive pulley 15 and the drive pulley 15 are opposed to each other and are inserted into a sleeve having a short length made of metal. This is compressed from the outer periphery and the both ends are joined to make endless. Or wire rope 16
In addition to untwisting both ends of the wire rope, a male thread is provided at one end of the wire rope and a female thread is provided at the other end.
【０００４】この場合、作業現場の状況に応じ、２０ｍ

とはいうまでもない。In this case, depending on the situation of the work site, 20 m
It goes without saying that a wire saw having the optimum front and rear lengths is prepared.

プーリー１５をＢ位置に後退させる。In this way, while the wire saw 13 is engaged with the drive pulley 15, while driving water into the moving surface of the wire saw 13 on the wall and the through hole 12, the drive pulley is driven. It is in position A due to hydraulic pressure. The concrete wall 11 is cut while applying pressure to the drive pulley 15 in the B position direction, that is, in the direction in which the wire saw 13 presses the wall. As the cutting progresses, the drive pulley 15 is retracted to the B position.

【発明が解決しようとする課題】しかし乍ら、上記従来

ヤーソーで、コンクリート構造物を切断加工した場合、
１０ｍ２程度の切断加工を行うと、ビーズ径は８ｍｍ程
度に摩耗し、且つ必らずしも全周に亘り均一に摩耗しな
いので寿命となる。However, in the above-mentioned conventional cutting method, the abrasion of the beads due to the cutting is considerably severe. For example, when cutting a concrete structure with a wire saw having an outer diameter of beads of 10 mm and a length of 20 m,
When the cutting process of about 10 m 2 is performed, the bead diameter is worn to about 8 mm, and it is not necessarily worn uniformly over the entire circumference, so that the life is reached.

６ｍ２、のものを多数切断する場合、上記ワイヤーソー
によれば、１箇目は問題ないが、２箇目に入ると寿命の
残は約４ｍ２となり、切断途中で寿命となるおそれがあ
る。The work to be cut is not limited to about 10 m, but has various sizes. For example, in the case of cutting a large number of ones with a cross section of 6 m 2 , according to the wire saw, there is no problem with the first piece, but when the second piece enters, the remaining life becomes about 4 m 2 and the life is reached during cutting. There is a risk.

切断溝に嵌め込まれず、切断の再開は困難となる。At the end of the life, the cutting process is restarted with a new wire saw after that, but if the bead diameter is 8 mm, the cutting groove width is 8.0 to 8.5.
mm, and a new wire saw with a bead diameter of 10 mm is not fitted into the cutting groove, and it is difficult to restart cutting.
【０００９】従って、２箇目の切断加工には、残寿命の

を再開、継続するものである。The present invention solves the above-mentioned disadvantages. First, a plurality of wire saws having different bead outer diameters are prepared in advance. Then, the cutting process starts with a wire saw equipped with one with a large outside diameter of beads, and when the wire saw reaches the end of its life and the wire saw needs to be replaced during cutting, the outside diameter of the previous beads The cutting process is restarted and continued with a wire saw equipped with beads of smaller diameter.

Is. The wire rope 1 is usually a stainless steel stranded wire, and a plurality of wires obtained by twisting fine stainless steel wires are twisted together. This steel fine wire is plated with copper or zinc for the purpose of rust prevention as it is or at the stage of twisting.

Ultra-hard, hard particles such as C particles dispersed and fixed in a metal matrix, or fixed on a metal base by electroplating, a ring shape that can be just inserted into the wire rope 1, Outer diameter (A 1 ) is 8 to 1
Approximately 0 mm, 3 is a rubber sleeve member (for example, an outer diameter of 7 to 9 mm), which is arranged and fixed together with the beads 2 on the wire rope 1. This sleeve member can be omitted.

論（Ａ２）より更に小径の群を準備することも出来る。FIG. 2 shows a wire saw having the same structure as in FIG. 1, but the outer diameter (A 2 ) of the beads is slightly smaller than (A 1 ) and is about 7 to 9 mm. This (A 1 ),
Prepare a large number of (A 2 ) wire saws. Of course, it is also possible to prepare a group having a diameter smaller than (A 2 ).

くなり、遂に寿命となる。However, first, the cutting process is started with the outer diameter (A 1 ). As shown in FIG. 3, the cutting groove width is initially large (A 1 ), but as the beads wear, it becomes as small as A 1 and finally the life is reached.
【００１５】その時は、（Ａ２）外径のワイヤーソーに

【００１６】このワイヤーソーの取替えにより、切断面
に段を生じるが、切断目的が主として、構造物やその一
部の破壊であるので支障とはならない。This replacement of the wire saw causes a step on the cut surface, but this is not an obstacle because the purpose of cutting is mainly to destroy the structure and a part thereof.
【００１７】従って、ビーズ外径の（Ａ１）（Ａ２）

不経済なく、スムースに切断加工を行うことが出来る。Therefore, the outer diameter of the beads (A 1 ) (A 2 )
By using each group of (A 3 ) one after another in combination, it is possible to perform cutting work smoothly without worrying about remaining life and uneconomical.
