Definitions
- the invention relates to a method and an apparatus for the continuous production of fiber-reinforced body from hydraulically settable compositions, which are applied in at least one layer of a predetermined width and thickness from one or more dispensers to a moving surface and glass fibers as reinforcement.
- DE 34 31 143 C2 describes a process for the production of moldings, for. B. plates, made of fiber-reinforced hydraulically settable masses, in which the mass is applied without fibers in a predetermined thickness on a base, whereupon coming from a cutting device sprinkled fiber chips in a doped amount on the surface of the mass and with a tool over the entire working range e be pressed into the mass, the mass being compressed at the same time.
- the disadvantage here is only a relatively small proportion of reinforcement material and also only in an outer area of the plate in a structurally unfavorable arrangement.
- DE-AS 24 56 712 discloses a method for producing molded articles from fiber concrete, in which
- Fibers are sprayed onto concrete that has not yet hardened, sprinkled or sprinkled on and then rolled or smoothed.
- the fibers are continuously cut with a cutting unit from G lasfasers rovi ngs. They can be applied in multiple layers and then cement can be powdered to absorb excess water.
- the fibers are intended to achieve a crack-free, better water-insulating concrete surface in the pool.
- the fibers are scattered and rolled in in a manual process with a cutting tool and a manual roller.
- the known methods and devices have in common that they only have one “good side”, namely on the surface facing the forming documents.
- the proportion of fibers in the concrete matrix is limited to approx. 5-6 percent by mass.
- premix a mixture known as a "premix”, which contains a homogeneous mixture of fresh concrete and glass fibers, to a base in a uniform layer thickness. Processing of "premix” finds its limits with the proportion of glass fibers to be added, because higher proportions make it difficult or impossible to process the mixture and the reinforcement content for thin slabs is generally too low.
- the invention has for its object to provide a method and an apparatus with which it is possible to produce fiber-reinforced panels with exactly predetermined and occasionally also small thickness, which if necessary have two smooth or structured "good sides” and with controllable dosing of Proportions of reinforcement material, especially with higher reinforcement proportions and with exact positioning of the reinforcement in statically stressed zones of the slab layer can be produced with high yield.
- the plates should be able to be processed into three-dimensional moldings immediately or subsequently, but in a fresh state.
- the layers are conveyed against one another and combined with a controlled pressure to form a product formed on both outer surfaces, subjected to thickness calibration, deflected in a discharge direction and removed.
- the method yields the advantage that the work steps compared to known processes are rationalized into one another in a continuous sequence, and inaccuracies such as are caused by the interaction of several work steps which are shifted in time and which are dependent on one another are largely avoided.
- fiber components of the reinforcement can far exceed the amount of about 5% by weight of the total matrix, which was previously regarded as the maximum limit, without restriction.
- the matrix mass penetrates into or through the laid-up fiber mats.
- the respective first matrix layer is placed on a permanently installed feed table with Rütte devices in front of the Conveyor belt applied. This enables an even more precise thickness calibration than on the conveyor belt and a guaranteed surface quality thanks to the possibility of rutting from below.
- One embodiment provides that a small proportion of glass fibers is added to the mass when it is being prepared.
- the concrete matrix prepared as a premix with the admixture of fibers already favors the cohesiveness and plasticity of the mass emerging from the dispensers as the first highly compressed layer, with a fiber content of less than 1% by weight, so that it acts in its movement as a dimensionally stable, non-tearing film.
- the application of this type further avoids undesirable trapping of air between the base and a first matrix layer.
- the mass of glass fibers can be mixed in an amount of 0.01 to 4% by weight, preferably between 1 and 1.5% by weight.
- the mass is applied to the shaping base in a continuous mass flow and extruded from case to case, the dispensers being set at a defined distance from the progressive documents. As a result, a predetermined thickness of the first laminate layer is achieved and maintained with high accuracy.
- Glass fibers made of AR, E, C, or ECR glass, metal fibers (Fibraflex), Mi krostah if fibers, plastic fibers, aramid fibers or carbon fibers can be used as the fiber material.
- the flat structures can be continuous yarns, rovings, bonded glass fiber mats, nonwovens, fabrics, grid fabrics, scrims (also multiaxial), fiber complex mats or combinations of these delivery forms.
- An embodiment essential to the invention provides that a mass layer can be injected between the reinforced layers during their union.
- a mass layer can be injected between the reinforced layers during their union.
- Styrofoam curl or other organic or mineral material in the form of plates or blocks an inseparable bond between the layers to be combined is achieved, the setting process is promoted and, in the case of a subsequent shaping, the plasticity of the plate is improved, which means that the still unbound plate-like product has no problem can be subjected to shaping, for example, into three-dimensional structures.
- Such a shape can be used, for example, for the production of corrugated sheets, channels, pipes and similar products.
- profiled cylinder rollers can be used.
- the individual matrix layers are calibrated by setting a distance between the mouthpiece of a dispenser or funnel and the base.
- the end product is precisely pre-calibrated by the dimension of the gap between the deflecting rollers and recalibrated using fine calibration rollers.
- a further measure according to the invention provides that the masses in the dispensers are degassed and / or compressed by shaking. Furthermore, the matrix layers can also be shaken on the substrates during or after their application and thus further compacted, the sheet-like structures being intimately connected to the matrix layer receiving them at the same time by the shaking movements.
- the layers are deflected while they are being combined using cylindrical rollers and are formed between the bases with a given pressure on both outer surfaces and are simultaneously connected to one another. In this way, an exact parallelism of the Surfaces of the product and a specified sheet thickness are achieved automatically with great accuracy without any further work steps. Furthermore, the freshly assembled layers can be supported and recalibrated in the area around the direction of discharge to the discharge direction using at least one support roller.
- a major advantage of the process is that it runs "cleanly”, largely avoids the emission of fiber and cement dust, produces little or no waste and thus satisfies the required workplace hygiene.
- a device for the continuous production of fiber-reinforced molded articles from hydraulically settable masses for carrying out the method according to the invention, comprising at least one movable base and above this feed hopper for the application of a mass layer on the base as well as fiber discharge and component devices and means for introducing the fibers into the mass layer is characterized in that these two counter-movable documents guided by a couple of drivable cylinder rollers and at least one application device assigned to each document, as well as an allocation device for glass fiber flat materials and means for integrating them into the visually applied mass has, and that the cylinder rollers form an adjustable gap between s ch.
- a feed hopper is arranged above the gap of the cylinder rollers.
- the device is, with great advantage, uncomplicated, compact in comparison to the multi-layer product that can be produced with it, and, at a relatively high production speed, enables high output with extreme accuracy of the layer sequence in the end product.
