Problems solved by technology

[0005] A disadvantage of the device described in WO 2005 / 061813 A1 is, on the one hand, that wedges of different shapes and materials are used, so that not only the manufacture of the device but also its correct setting on a tension member is associated with high costs
[0009] By using high-strength materials for the wedges, as described in WO 2004 / 003316 A1, it is not sufficient to achieve such a stress distribution, so the efficiency of the force introduction into the tension member is limited

Embodiment Construction

[0034] figure 1 Shown is a device 1 for introducing force into a tension element 2 consisting of fiber-reinforced plastic webbing laminations, comprising a clamping element 3 arranged on the tension element and having a contact surface with the tension element and at least one A rigid sleeve 4 is arranged around the clamping element and the tension part and thus exerts a clamping pressure on the tension part via the clamping element.

[0035] According to the invention, the clamping element consists of a plastic having a modulus of elasticity in the range of 1000 to 5000 MPa, a flexural tensile strength of ≧25 MPa, in particular 50 to 150 MPa, and a compressive strength of ≧25 MPa.

[0036] The stated values ​​relate to measurements according to standard ISO 604 for modulus of elasticity and standard ISO 178 for flexural tensile strength and compressive strength.

[0037] As plastic for the clamping element, in principle any desired plastic with corresponding physical propert...

Abstract

The invention relates to a device (1) for introducing a force into tension members (2) made of fiber-reinforced plastic flat strip lamella, comprising at least one clamping element (3), which is arranged on the tension member (2) and has at least one contact face with the tension member (2), and at least one rigid sleeve (4), which is arranged around the at least one clamping element (3) and the tension member (2) and thereby exerts a clamping pressure on the tension member (2) via the clamping element (3), wherein the clamping element (3) consists of plastic material having a modulus of elasticity ranging between 1000 and 5000 MPa, bending tensile strength of >= 25 MPa and pressure resistance of >= 25 MPa.

Description

technical field [0001] The invention relates to a device according to the preamble of the first claim for the introduction of forces into a tensile element consisting of laminates of fiber-reinforced plastic webbing. Furthermore, the invention relates to a method for introducing force into such a tension element, the use of a corresponding device, a tension element with one or more devices according to the invention, and a method for use in accordance with the present invention. The method of strengthening the supporting structure in the case of the device of the invention. Background technique [0002] The reinforcement of supporting structures, for example when improving existing buildings, by installing tension members made of laminates of fiber-reinforced plastic webbing, which are glued to the supporting structure under tension, are known and There are various advantages over reinforcing the support structure by means of a steel structure. Special importance is given ...
