Abstract

주입식 앵커의 앵커 바아들(2)을 연결하기 위해, 그 앵커 바아들은 그들의 외부 나삿니(4)에서, 대응하는 내부 나삿니(5)를 가진 연결 슬리이브(1)내에 나사결합된다. 연결 슬리이브(1)내에 나사결합된 2개의 앵커 바아들(2) 중 하나가 단부 테이퍼부에 의해 형성된 경사면(8)을 가지고 있고, 연결 슬리이브(1)의 내부 나삿니(5)의 차단부(6)상에 얹힌다. 두번째 앵커 바아(2)는, 그의 단부면(9)이 다른 앵커 바아(2)의 단부면(9)상에 완전히 놓일 때까지 연결 슬리이브(1)내에 나사결합된다. 이것에 의해, 드릴링 작동중 양호한 힘 전달이 보장되고, 드릴링 작동중에 연결 슬리이브(1)가 회전하는 것이 방지된다.In order to connect the anchor bars 2 of the injection anchor, the anchor bars are screwed in their outer thread 4 in a connecting sleeve 1 with a corresponding inner thread 5. One of the two anchor bars 2 screwed into the connecting sleeve 1 has an inclined surface 8 formed by an end taper, and a blocking part of the internal thread 5 of the connecting sleeve 1. (6) Put it on. The second anchor bar 2 is screwed into the connecting sleeve 1 until its end face 9 lies completely on the end face 9 of the other anchor bar 2. This ensures good force transmission during the drilling operation and prevents the connecting sleeve 1 from rotating during the drilling operation.

Claims

Coupling for anchor bar 2 of a (injection) drilling anchor, comprising a coupling sleeve 1 having an internal thread 5, and in the connecting sleeve, anchor bars 2 having external threads. In the coupling for the anchor bar, in which the ends of the screw are screwed so that the facing end faces 9 of the anchor bars are completely adjacent to each other, the anchor bars 2 are connected to the connecting sleeve 1. In order to limit the depth of screwing in), two threaded portions 5 ', 5 "are provided in the connection sleeve, which are arranged in the connection sleeve 1 and are separated from each other by cutting one threaded turn. Anchor bar coupling, characterized in that.

2. A coupling as claimed in claim 1, wherein the blocking portion of both threaded portions (5 ', 5 ") is cut out of one threaded turn.

3. Coupling for anchor bar according to claim 1 or 2, wherein the blocking part of both threaded parts (5 ', 5 ") is located in the middle of the connecting sleeve (1).

4. An inclined surface (8) is provided at the end of the anchor bars (2), the inclined surface (8) being end surface (9) from the outside of the anchor bar (2). Coupling for anchor bar extending up to).

5. The method according to claim 4, wherein only one of the two anchor bars (2) screwed into the connecting sleeve (1) is adjacent to the end of one of the two threaded portions (5 ', 5 ") in its inclined surface (8). Coupling for anchor bar.

Coupling according to one of the preceding claims, wherein the connecting sleeve (1) is a cast part, in particular a steel cast part.
