TEXTILE-REINFORCED CONCRETE COMPONENT

摘要

A concrete component includes a fiber reinforcement structure (12), formed by a grid arrangement (15). At least some of the rods extending in the X or Y direction are preferably designed as double rods having a joined cross-section or having sub-cross-sections separated from each other by a gap (20). Such double rods can be arranged in a grid structure both at right angles to each other and at other angles to provide a triangular structure, a hexagonal structure, or the like as a grid. Fiber reinforcement structures (12) made of a plastic-impregnated fiber material, such as epoxy-resin-bonded glass fibers having long fibers (endless fibers), in the particular rod longitudinal direction and without bonding among each other (ravings) can construct an adequately load-bearing composite with the concrete body (II). The steel rods can act as reinforcement, wherein harmful effects on the concrete, in particular wedge and gap effects, do not occur.

1. Concrete component comprising:
a fiber reinforcement structure (12, 12′) with a plurality of first fiber strands (17a) arranged in a first direction (x) and a plurality of second fiber strands (18a) arranged in a second direction (y), said fiber strands forming a first grid array (15, 15′) with intersection points at which the first fiber strands (17a) and the second fiber strands (18) are connected to each other, wherein each of the first fiber strands (17a) and the second fiber strands (18a) have a plastic portion; additional fiber strands (17b, 18b, 27, 28) having a plastic portion, wherein the additional fiber strands (17b, 18b, 27, 28) are connected, at least in sections, to the first fiber strands (17a) and/or to the second fiber strands (18a), respectively; and a mineral body (11) which consists of a filler and of a binder, and in which the fiber reinforcement structure (12) is embedded.
