Abstract

A tie rod (1) for joining opposite side sections (23a, 23b) of a casting formwork (21) , the tie rod (1) being provided with a mid portion (3) and two rod end portions (5a, 5b) and there being formed, in the transitions between the mid portion (3) and either rod end portion (5a, 5b) at least one abutment surface (7) which is arranged to rest supportingly on an internal side surface (23c) of the side sections (23a, 23b) , and the rod end portions (5a, 5b) including rests (9) for wedge devices (11) for securing the side sections (23a, 23b) of the casting formwork (21) , and the tie rod (1) including a stem (2) of great tensile strength and a surrounding mantle (2a), the mid portion (3) and the mantle (2a) of the stem (2) being formed as a continuous structure, the stem (2), the mantle (2a) and mid portion (3) being formed of non- corrosive materials.

Claims (23)

1. A tie rod (1) for joining together opposite side sec-tions (23a, 23b) of a formwork (21), the tie rod (1) be-ing provided with a mid portion (3) and two rod end por-tions (5a, 5b) and there being formed, in the transitions between the mid portion (3) and either rod end portion (5a, 5b), at least one abutment surface (7) which is arranged to rest supportingly on an internal side surface (23c) of the side sections (23a, 23b), and the rod end portions (5a, 5b) including rests (9) for wedge devices (11) for securing the side sections (23a, 23b) of the casting formwork (21), characteri-zed in that the tie rod (1) includes a stem (2) of great tensile strength with a surrounding mantle (2a), the mid portion (3) and the mantle (2a) of the stem (2) being formed as a continuous structure, the stem (2), the mantle (2a) and mid portion (3) being formed of non-corrosive materials.
2. The tie rod (1) in accordance with claim 1, cha-racterized in that the tie rod (1) is formed of a composite material.
3. The tie rod (1) in accordance with claims 1-2, cha-racterized in that the stem (2) is fibre-reinforced in the axial direction of the tie rod (1).
4. The tie rod (1) in accordance with claims 1-2, cha-racterized in that the mantle (2a) and the mid portion (3) are formed of the same type of material.
5. The tie rod (1) in accordance with claims 1-4, cha-racterized in that the mantle (2a) and the mid portion (3) are joined by fusion of the material forming the mantle (2a) and the material forming the mid portion (3).
6. The tie rod (1) in accordance with claim 1, cha-racterized in that the mantle (2a) and the mid portion (3) are joined by gluing.
7. The tie rod (1) in accordance with claim 1, cha-racterized in that the mid portion (3) is provided with means (7c, 7d, 57a, 57b, 58a, 58b) for non-releasable engagement with a surrounding casting ma-terial (31) when this has been filled into the casting formwork (21) and has set.
8. The tie rod (1) in accordance with claim 1, cha-racterized in that the mid portion (3) and the stem portion surrounded by the mid portion (3) is arranged to form a watertight, non-releasable, through plug in a completed cast structure (31).
9. The tie rod (1) in accordance with claim 1, cha-racterized in that the abutment surface (7) is formed by the mid portion (3) exhibiting, towards its end portion, a widened cross-section (7a, 57b).
10. The tie rod (1) in accordance with claim 1, cha-racterized in that at least one portion of the mid portion (3) exhibits a cross-section exhibiting, when the cross-section lies perpendicularly to the cen-tre axis of the tie rod (1), a non-circular shape.
11. The tie rod (1) in accordance with claim 1, cha-racterized in that the mid portion (3) is provided with a plurality of concentric cross-sectional widenings (58b).
