Definitions
- the invention relates to a clamping device for a band-shaped tension member on a concrete surface Structure.
- the required prestress must be on the concrete surface lying band-shaped tension members are applied, as long as the adhesive layer between the band-shaped tension member and the concrete surface has not yet hardened.
- the both ends of the prestressed band-shaped tension member must be permanently connected to the structure. This serves a tensioning device of the type concerned here.
- a tension drive is used to apply the preload required, for example one or more has hydraulic cylinders. These tension drives are said to be removable so that you can use it again. Therefore is a permanent one after the tensioning process Anchoring of the band-shaped tension member required. This Anchoring should be such that it is only slightly above the concrete surface protrudes in a simple manner To enable corrosion protection.
- the object of the invention is therefore a tensioning device to create the type mentioned in the simple Way of applying the biasing force and effective Anchoring of the band-shaped tension member enables, as few parts as possible remain permanently at the clamping point.
- the base frame consists of one with the The structure can preferably be permanently connected by gluing Base plate and preferably removable by means of screws attached guides for the tension slide.
- This shared Execution of the base frame makes it possible for the Clamping process only temporarily required guides End of the tensioning process and only the Leave the base plate permanently on the structure.
- the tension slide from a lower plate and there is a screwed clamping plate between them the band-shaped tension member can be clamped.
- This execution on the one hand enables a simple, namely clamping Connection between the tension slide and the band-shaped tension member; on the other hand, the tension slide can Completion of the tensioning process and anchoring of the band-shaped Tension member by means of the anchoring device in simple Be released from the band-shaped tension member.
- the anchoring device has according to a preferred Embodiment of the inventive concept of a clamping anchor plate on that with the base plate under clamping the band-shaped Tension member is screwed.
- the clamping anchor plate is preferably can also be glued to the band-shaped tension member.
- the combination of clamping and gluing in the area of Anchoring device increases the safety of the traction transmission in the anchoring area because to the Stiction by the clamping pressure the adhesive connection come in addition. This means that the band-shaped tension member even when the Screw pre-tensioning forces guaranteed. Moreover is the problem of corrosion protection due to the adhesive application solved in the clamping gap.
- the clamping device shown in the drawing is used to a band-shaped tension member 1, for example one Steel slat with adhesive on a concrete surface 2 of a structure 3 is attached to pre-stress before the Adhesive connection between the tension member 1 and the concrete surface 2 hardens. It also serves the purpose of Clamping section of the tension member 1 on Anchor structure 3.
- the clamping device has a base frame that a base plate 4 and screwed side Guides 5 exists.
- the base plate 4 is in one Recess 6 of the concrete surface 2 by means of anchor screws 7 and an adhesive layer 8 permanently attached.
- the guides 5 designed as lateral longitudinal rails are detachably attached to the base plate 4 by means of screws 9.
- Extend tension member 1 is a tension slide 10 in Longitudinal direction of the tension member 1 guided.
- the Tensioning carriage 10 consists of a lower plate 11, the under the band-shaped tension member 1 is arranged and laterally under the guides 5 engages, and one screwed to it
- Clamping plate 12 which is on the top of the band-shaped Tension member 1 is located and laterally over the guides 5. By tightening the lower plate 11 and the clamping plate 12 connecting screws 13, the band-shaped tension member 1 on Tension slide 10 fastened by clamping.
- a tension drive 14 in the illustrated embodiment has two hydraulic cylinders 15 is between an end face 16 of the clamping plate 12 of the clamping slide 7 and an angled support surface 17 each Section 5a of the guides 5 of the base frame used.
- a clamping anchor plate 21 is now used (FIG. 2), being between the underside of the clamping anchor plate 21 and the Top of the band-shaped tension member 1 an adhesive application he follows.
- the clamping anchor plate 21 is fastened by means of screws 22 screwed to the base plate 4, the band-shaped Tension member 1 is clamped. This state is in FIG. 2 shown.
- the band-shaped tension member 1 is at its other end by means of anchored to the anchoring device described and anchoring device 23 shown in FIG. 3 equivalent.
