Definitions

  • the invention relates to a prefabricated component for structures, preferably in prefabricated construction with a core element and at least one reinforcing part absorbing tensile forces.
  • Panel-shaped components of the type specified at the outset are used as prefabricated wall or ceiling elements. They usually contain a slab core made of lightweight concrete, which is reinforced with a reinforcing mesh inserted into the slab. The reinforcement has the task of absorbing the tensile or transverse forces occurring in the ceiling or wall elements, while the concrete is intended to absorb the compressive forces. The strength values can be increased by adding concrete in the slab core.
  • the object of the invention is to improve the known prefabricated components in such a way that they have high tensile strength and durability with simple means and without ne can be transported, handled and processed on site.
  • the reinforcing part is designed as a flat material part made of fiber-reinforced plastic, which is fixed to a broad side surface of the core element in a form-fitting and / or cohesive manner.
  • a layer-forming plate or film can be considered as the flat material part.
  • the flat material part expediently has a binder matrix made of plastic and a fiber fabric or scrim embedded in it. It is preferably glued to at least one of the broad side surfaces of the core element with an epoxy resin adhesive.
  • a preferred embodiment of the invention provides that the flat material part has a plurality of nub-like anchoring members projecting on one side, with which it engages through openings in the broad side surface and into the core element and is anchored there in a form-fitting manner.
  • the anchoring elements are embedded in the core element.
  • the flat material parts are placed in a formwork against the formwork wall in such a way that their anchoring members point inwards and are encased in liquid concrete.
  • the core element advantageously consists of concrete, lightweight concrete, gas concrete or gypsum.
  • the binder matrix of the flat material can consist of a thermoset, for example from the group of epoxy resin, polyester resin, vinyl resin.
  • the binder matrix preferably consists of a thermoplastic from the group consisting of polyamide, polymethyl methacrylate, polyphenylene sulfide, polypropylene, polye ethylene terephthalate, polybutylene terephthalate, polyetherimide, styrene polymer, polyether ether ketone.
  • the fibers of the flat material part are expediently selected from the group consisting of carbon fibers, glass fibers, aramid fibers, polyethylene fibers, basalt fibers, natural fibers.
  • a further preferred embodiment of the invention provides that a plurality of reinforcement parts are provided which penetrate the core element, the widened ends of which are flush with the broad side surfaces of the core element and are integrally bonded, preferably glued, to the at least one flat material part.
  • the reinforcement parts expediently have a double-T profile and consist, for example, of metal, in particular of aluminum or steel, or of a fiber-reinforced polymer material.
  • a fiber fabric or scrim is impregnated with a binder, heated in a continuous process and then cooled and pressed again, with knob-like anchoring parts being molded on one side in the course of the manufacturing process, preferably being pressed out of the flat material.
  • the prefabricated components according to the invention are preferably used as wall elements, ceiling elements or supports for prefabricated structures.
  • Figure 1 shows a section through a plate-shaped component with positively anchored reinforcing parts made of fiber-reinforced plastic.
  • Fig. 2 shows a section through a component with internal reinforcement and on the wide surfaces glued reinforcing parts made of fiber-reinforced plastic.
  • the components shown in the drawing are intended as wall or ceiling elements for buildings in precast construction.
  • the plate-shaped components have a core element made of concrete, lightweight concrete, gas concrete, plaster.
  • the core element 10 carries on its broad side surfaces 20 each a plate or sheet-shaped flat material part 12 made of fiber-reinforced plastic.
  • the flat material part 12 is cast into the core element 10 with nub-like anchoring members 14 projecting on one side and thus anchored in a form-fitting manner.
  • the core element 10 additionally contains a plurality of reinforcement parts 16 which pass through the core element, the widened ends 18 of which end flush with the broad side surfaces 20 of the core element 10.
  • the flat material parts 12 are glued onto the broad side surfaces 20 of the core element and the ends 18 of the reinforcement parts 16 with the aid of an adhesive layer 22.
  • the reinforcing parts 16 having a double-T profile can consist of a metal, such as aluminum or steel, or of fiber-reinforced polymer material. In the latter case, the flat material parts 12 can also be welded onto the ends 18 of the reinforcement parts under the action of pressure and heat.
  • the flat material parts 10 serve to reinforce the core element and have the task of absorbing tensile and transverse forces and preventing concrete material from breaking out of the core element during transport, assembly and processing in the finished state.
  • the invention relates to a prefabricated component for prefabricated part construction with a core element 10 and at least one reinforcing part 12.
  • the reinforcing part is designed as a flat material part 12 formed of fiber-reinforced plastic, which is fixed to a broad side surface 20 of the core element 10 in a form-fitting and / or cohesive manner.

Abstract

La présente invention concerne un élément de construction préfabriqué destiné à des bâtiments dans le domaine de la construction préfabriquée, ledit élément de construction comprenant un élément central (10) et au moins une partie de renfort (12). Afin de résister à des forces de traction et de cisaillement élevées sans risque de formation de fissures, la partie de renfort se présente sous la forme d'une partie plane (12) constituée de matière plastique renforcée par fibres, et fixée par liaison de forme et/ou de matière, à la surface du côté plat (20) de l'élément central (10).
