丸ねじに近いものを使用することが一般的である。It is common practice to connect lock anchors, piercing rods and extension rods of the same type to each other with a threaded connecting member. For this reason, the threaded members of two parallel piercing rods or lock anchors that are articulated to one another are articulated by articulation sleeves having external threads and corresponding internal threads. Especially in perforated rods, these threaded members simultaneously act as couplings for coupling rock hammers or other drives. Therefore, a high load is applied to these screw members, and severe dirt is generated due to polluted soil water. In consideration of the added high load and terrible stains, in order to facilitate the handling of these joints, a round screw is usually used rather than the bottom of the screw turning part, that is, a triangular screw in which dirt is clogged at the sharp end of the screw groove. Or, it is common to use a screw close to a round screw.

できる。SUMMARY OF THE INVENTION It is an object of the invention to provide a connecting sleeve for threaded members such as piercing rods, lock anchors, etc., which has a thread which is easy to manufacture at low cost and which guarantees high strength.
This object is composed of a tubular body having an internal screw and an external screw, and the internal screw can be screwed into a threaded member such as a piercing rod or a lock anchor, and the internal screw is provided inside the tubular body with a support mechanism such as a mandrel. This can be achieved by an articulating sleeve according to the invention, which is formed by effectively moving the material inward according to the formation of external threads on the outside.

えた連接スリーブの製造費は相当低減される。The connecting sleeve of the present invention is based on the fact that it has threads formed directly by engaging a forming tool with the surface of a tubular body in the well-known non-cutting forming process. It has internal threads formed on the inside corresponding to the external threads formed on the outside as a result. The connecting sleeve is composed of a tubular body, which has an externally threaded external thread, the profile of which is annealed into a round thread. Since the size of the internal screw formed on the tubular body is determined depending on the size of the screw of the threaded member such as the perforated rod lock anchor that is screwed into the connecting sleeve, the internal thread formed between the screw turning portions when screwed together. The minimum clearance is given. Internal threads formed in this manner have significant advantages as they can be formed in a single configuration. Therefore, the manufacturing cost of the articulating sleeve with internal threads is considerably reduced compared to the thread cutting process.

れる。The connecting sleeve used for connecting the extension rod to the lock anchor, the drilling rod or the like according to the present invention is particularly effective when the connecting sleeve is reinforced by the above-mentioned molding process when an extremely high mechanical load is applied, High strength is realized. Further, in these cases, since the soil water due to perforation may cause serious damage, in order to ensure satisfactory handling of the screw member and the connecting sleeve in such a condition of use, the connecting sleeve should not be contaminated at the sharp end of the thread groove. Round or similar screws are preferred over triangular screws that clog soil. Since the articulating sleeve according to the invention is related to the flow of material, it is independent of the actual shape of the shape, and is suitable for the production of round threads of the type mentioned above, in which no sharp edges are formed in the thread groove, such as occurs with triangular threads. Limited from the start.

In the illustrated embodiment of the internal thread of the articulating sleeve 4 which is articulated in the form of a circular thread, the circular thread does not clog the drilled soil at the sharp edges of the thread groove like a triangular thread does, so the rock drilling operation Despite the terrible fouling that occurs inside, easy handling can be achieved. According to the invention, the internal thread of the tubular body 4 forming the connecting sleeve is formed by a non-cutting forming process, here a cold forming operation, in which the connecting sleeve 4 is provided with a forming tool on the outside 7. 1 is used to provide the contour shown in FIG. 1 and effectively move the material inwardly to complement the outer contour to form the internal thread. A description will be given below with reference to FIGS. 2 to 4. As is apparent from the connecting sleeve 4 shown in FIG. 2, the outer side 7 is composed of the spiral turning deforming portions 8 having a substantially arcuate cross section, and the slightly deformed smooth surface between the independent spiral turning deforming portions 8. The part 9 is formed.

And 13 are provided. A well-known screw member having a function of supporting the groove wall of the excavation hole can be inserted into the end portion of the connecting sleeve 4. These screw members correspond to the piercing rod 1 and the extension rod 5 shown in FIG.
However, these threaded members are not shown for the sake of brevity. By the rotation of the connecting sleeve 4 with respect to the screw member,
In order to realize the removal or the attachment of the screw member, the connecting sleeve 4 is provided with an auxiliary mechanism, not shown in the drawings, which causes a rotary movement in a similar manner. In the simplest case, this auxiliary mechanism can be a hole into which the lever can be inserted. It is also possible to weld to the connecting sleeve 4 a nut or a shaping tube which has the effect of enabling a rotary movement by means of a corresponding tool. If desired, a plastic nut can be cast or pressed on the outer surface of the articulating sleeve 4.
