Definitions
- Tie rods in particular for securing rock walls, and methods for producing such a tie rod
- the invention relates to a tie rod for construction purposes, in particular for securing rock walls, with an anchor rod consisting of a polymer composite and having a thread at its head end for receiving a pressure nut which can be screwed onto the thread of the anchor rod and is preferably supportable against a pressure plate.
- Tension anchors of this type are mainly used for the permanent securing of unstable mountain zones, for system anchoring in order to increase the construction resistance as well as for security measures in underground and special civil engineering.
- the anchor rods are used in the bores of the rock walls to be secured, glued with an anchor mortar or anchor resin and braced with the pressure plate pushed on the head side and a pressure nut screwed onto the thread.
- the anchor rod mainly consists of steel or glass fibers, which are glued in a special process with polyester resin or epoxy resin. The sawtooth-like thread is cut into the anchor rod. It is perceived as a disadvantage that the glass fibers are cut at the interfaces, which causes an undesirable weakening of the material. Proceeding from this, the object of the invention is to develop a tie rod of the type specified at the outset and a method for its manufacture, which simplifies the manufacture of the anchor rod and yet a higher tensile force can be achieved.
- the solution according to the invention is primarily based on the idea that with continuous reinforcing fibers an increased tensile force can also be achieved in the area of the thread.
- the polymer composite has a large number of reinforcing fibers which extend over the entire length of the anchor rod and are embedded in a binder matrix made of thermoplastic material and are uninterrupted in the thread area.
- the thermoplastic it is possible to form the thread without cutting into the anchor rod, preferably under the action of pressure and heat.
- the glass transition point of the thermoplastic used should suitably be above 100 ° C, while the flow transition area should begin above 160 ° C.
- the reinforcing fibers contain carbon fibers or are designed as such.
- the hybrid fibers used for this purpose mainly consisting of carbon, glass and / or aramid fibers, which as a whole have a high shear strength corresponding to the steel.
- the reinforcing fibers form a braided hose impregnated with the binder, in which purely axially aligned carbon fibers or carbon fiber strands are expediently arranged, into which a large number of glass fibers or glass fiber strands can be predominantly braided in the circumferential direction.
- thermoplastic from the group of polyolefins, vinyl polymers, polyamides, polyesters, polyacetals, polycarbonates, thermoplastic polyurethanes and ionomers is advantageously provided as the binder matrix.
- the thermoplastic binder can be plasticized under the action of heat and at the same time swellable.
- a multiplicity of endless reinforcing fibers are expediently embedded in the binder matrix made of thermoplastic material in the coextrusion process or pultrusion process.
- the thread can be subjected to pressure and preferably heat can be molded into the anchor rod without cutting and without separating the reinforcing fibers.
- an initially dry braided tube formed from reinforcing fibers can be impregnated with liquid thermoplastic binder and cured to form the tie rod in order to produce the tie rod according to the invention.
- the thread and, if appropriate, a plurality of transverse grooves are expediently formed in the anchor rod and in the braided hose before the binder has hardened.
- the anchor rod inserted into the borehole can be heated locally via its central cavity beyond the flow transformation point of its binder and can be connected to the borehole wall in a cohesive and / or form-fitting manner. If a swellable binder is used, the anchor rod can additionally be heated locally with swelling of the binder. For local heating of the anchor rod, a heating lance is preferably inserted into the bore of the anchor rod and heated electrically.
- Figure 1 is a side view of a tie rod, consisting of anchor rod, pressure plate and pressure nut in an exploded view.
- Fig. 2 shows an enlarged section of the anchor rod in a longitudinal section.
- the tie rod shown in the drawing is designed as an adhesive anchor. It is particularly suitable as a rock anchor for the permanent and temporary securing of unstable mountain zones and for increasing the stability of the mountains when building tunnels and tunnels. It comprises an anchor rod 10, in which a head-side thread 12 is formed, a pressure plate 14 and a pressure nut 16 which can be screwed onto the thread 12 of the anchor rod.
- the anchor rod has a central cavity 22 and is protected at its tip by a removable cap 24. It consists of a polymer composite with reinforcing fibers 18 consisting predominantly of carbon fibers (hybrids), which are embedded in a binder matrix 20 made of thermoplastic material.
- the endless reinforcing fibers 18 are expediently embedded in the binder matrix 20 in the coextrusion process or in the pultrusion process and cut to the desired anchor length after curing.
- the thermoplastic binder matrix 20 ensures that the anchor rod
- the thread 12 can accordingly be introduced into the prefabricated anchor rod 10 under the action of pressure and, if appropriate, heat without breaking the reinforcing fibers 18. As a result, there is no inadmissible weakening of material in the area of the thread. Furthermore, transverse grooves 26 spaced apart from one another can be pressed into the anchor rod 10 over the entire length and ensure better anchoring in the injected material.
- the invention relates to a tie rod for building purposes, in particular a rock anchor designed as an adhesive anchor.
- the tie rod has an anchor rod 10 consisting of a polymer composite and having a sawtooth-like thread 12 at its head end for receiving a pressure nut 16 which can be supported against a pressure plate 14 and which is screwed onto the thread 12 of the anchor rod.
- the polymer composite of the anchor rod 10 has a large number of reinforcing fibers 18 which extend over the entire length of the anchor rod and are embedded in a binder matrix 20 made of thermoplastic plastic and are uninterrupted in the thread region.
- the thread 12 can be formed into the anchor rod 10 without cutting under the action of pressure and possibly heat.
