Definitions
- the invention relates to a reinforcement bar for mineral building materials, in particular for concrete.
- a reinforcement bar for concrete construction which is designed as a fiber-reinforced plastic profile, the plastic profile being produced using a lost formwork consisting of plastic.
- the material of the formwork is unrolled from a drum and transported in the direction of a pultrusion device, where it is expanded from the usually almost closed tube shape before being fed in and is filled with the pultrudate. The widened ends are then returned and the formwork is permanently closed. The pipe string is then heated.
- a reinforcing fabric for installation in building facades which can also be used for roofs, cladding or walls, in which electrically conductive threads are provided which are arranged essentially parallel and at intervals from one another, the textile threads having a thermoplastic coated are tet and the electrically conductive threads are embedded in the thermoplastic.
- DE 27 53 858 describes a process for producing fiber-reinforced concrete moldings, in which a lattice-like thread scrim is incorporated into cementitious masses, the thread scrim being first provided with pressure-sensitive adhesive before it is incorporated into the cement mass and then exposed to a stream of fibers which stick to the scrim and penetrate it.
- the lattice-like reinforcement is intended to reinforce the concrete component in directions transverse to the lattice plane.
- the object of the invention is to replace the concrete reinforcement bars previously made of steel with plastic material, in particular to create a reinforcement bar that can also be used in prestressed concrete.
- the procedure is to impregnate a strand of stretched or stretched filaments with a thermoplastic.
- the thermoplastic material should also encase the rod thus formed, so that it is ensured that the outer wall of the rod thus produced consists of thermoplastic material, but the core of filaments, which provide the required strength.
- the filaments made of carbon, glass, aramid, polyethylene or basalt stand, a mixture of these fibers can also be selected.
- carbon fibers are used which are not sensitive to corrosion, wherein - if the filaments consist of glass fibers - there is a certain sensitivity to corrosion here.
- a reinforcement bar produced in this way can be welded or glued to other reinforcement bars, so that a reinforcement can be produced which has strength in all directions.
- such a reinforcement bar can be formed so that it can be adapted to any shape of the concrete structure.
- the individual rods they can also be glued, but the welding produces a much higher strength, for which the casing of the rod made of thermoplastic is particularly suitable.
