Definitions

  • the present invention relates to the technical field of construction technology and in particular a half-shell element for producing a hollow body according to claim 1 and a hollow body consisting of a combination of interconnected half-shell elements according to claim 18.
  • the invention further relates to a tool for producing a hollow body according to claim 21 and Method for producing a hollow body using the tool according to claim 22.
  • the invention also relates to a method for connecting hollow bodies according to claim 23 and a preferred use of this hollow body according to claim 24.
  • Hollow bodies made of a plastic material are usually cast in concrete layers in order to make them lighter and at the same time less expensive. For this they are used in steel baskets, which make the concrete element to be manufactured at the same time more sustainable.
  • the applicant spherical closed hollow body as well as downwardly open or closed hollow half-shell elements known that are used for the production of particularly efficient concrete ceilings A disadvantage of the closed hollow bodies, however, is that their production requires a blow molding process, which is complicated and expensive. In addition, this method requires thicker wall thicknesses of the products, whereby the hollow body is not only expensive, but also unnecessarily heavy. Downwardly open half shells can indeed be produced in a simpler and cheaper injection molding process, but have the disadvantage that their displacement volume by flowing Concrete is reduced and the required concrete volume can not be precisely determined and controlled.
  • An essential point of the half-shell element according to the invention is that it is particularly easy to handle.
  • For producing a hollow body from this element is not a different, complementary element required, but again exactly the same.
  • a different number of complementary elements can be delivered to a construction site.
  • the latter can lead in particular to considerable loss of time and thus to additional costs, if the elements by sea over long distances such. B. from Europe to Asia.
  • their transport weight is reduced since the elements can be injection-molded and thus can be designed with smaller wall thicknesses, for example, of between 1 mm and 1.5 mm.
  • their production in large quantities is cheaper and faster.
  • the at least one guide is formed as a groove for gripping around an edge region of the further half-shell element.
  • the elements could be attached by simple clips, plugs, rivets or screws together.
  • a groove formed as a guide ensures both an easy to manufacture as easy to handle and at the same time reliable guidance and attachment of the elements together.
  • the length of wall thickness of the guide can be selected accordingly and their mutual clamping can be influenced in order to ensure a firm holding of the elements in the end position.
  • This end position is preferably secured by a latching hook and a locking surface is provided for locking on a complementary locking surface of a complementary latching hook of the further half-shell element, which are arranged opposite each other in approximately the middle of a first half circumference of the peripheral edge.
  • the other element locked so that in its final position on the other element, and can not, for example, when fitting the elements in steel baskets or when laying steel reinforcements on the filled baskets away from its position slip. This makes it exceptionally easy to handle both by hand for smaller lots as well as in an automated manner for large quantities and beyond reliable in its application.
  • a particularly easy positioning and locking of the half-shell elements to each other is ensured by both sides of the latching hook and the locking surface on the peripheral edge projections or notches are formed to engage in complementary notches or complementary projections of the other half-shell element.
  • the half-shell element may be in the form of a hemisphere or ellipsoid to make it available for its specific application. But it can also have a pole-side flattening, which is useful. This also allows that such a shaped element is also easy to handle when a same element is to be postponed. For this purpose it can be stored without e.g. roll away. The same applies to a hollow body, which was composed of two of the elements.
  • the flattening preferably has a circumferential shoulder with an enclosed, indented bottom surface, which in combination significantly increase the rigidity and thus stability of the element.
  • the bottom surface may be provided with information on or impressed on the half-shell element. This information may e.g. Information on the manufacturer, for the use, for the production or indications of protective rights etc. include. This also increases the handling of the element. An additional preparation useful for this purpose, e.g. Labeling is unnecessary.
  • the circumferential shoulder When installing a half-shell element with half-shell turned downwards, it should be possible to avoid any air entrapment on its indented bottom surface. In order to reliably prevent this, it is preferable for the circumferential shoulder to have at least one channel which extends extends as an extension of the bottom surface to an outer surface of the half-shell element. This allows the air to escape from the bottom surface to an outer surface of the element.
  • the half-shell is turned upwards, rain or condensation water is discharged from the engaged bottom surface to the outer surface of the half-shell element.
  • a defined displacement effect of the half-shell element is achieved in a particularly simple and reliable manner.
  • the element can also be used irrespective of weather conditions, since in particular the formation of ice layers is prevented which endanger its intended use.
  • the bottom surface in extension of the at least one groove is preferably provided with at least one respective elevation at the level of the shoulder.
  • the at least one protrusion preferably provided with a through hole which connects an inner and an outer side of the half-shell element.
  • a V-shaped web which is open towards a latching hook and / or a latching surface is preferably formed on the outer surface in order to prevent water draining outward from the latching connection and thus into the half-shell element.
  • stiffening ribs extend on its inner surface, which extend in a star shape starting from the pole of the element. These are preferably dimensioned and shaped such that they are stacked on the outer surface of a half-shell element, abut complementary half-shell element. This is in particular a defined vertical stacking of the individual elements into each other or ensures each other, which in turn increases their handling and also reduces their transport volume and thus the transport costs.
  • this preferably has an outer surface which is provided with at least one first clip for clamping a rod.
  • the clips are aligned in a connecting direction of the half-shell elements in which a number of elements are to come one behind the other. This eliminates the usually required steel baskets that hold the half-shell elements in a desired position.
  • the half-shell elements transmit the forces that were previously derived on the oblique support rods of a basket.
  • the number of interconnected half shell elements is limited only by the length of an available rod.
  • the clipping of the bars is particularly easy and quick to perform compared to fitting the half-shell elements into a basket, and also allows for a requirement-dependent variable arrangement of the elements along a bar. Since no longer whole baskets, but only e.g. Simple steel strands are needed, both related material and transport costs. In addition, such strands can also be ordered on site, so that their central provision is eliminated and their decentralized distribution is possible.
  • the outer surface of a half-shell element can be provided with at least one second clip which is rotated by an angle of greater than 0 ° to 90 ° to the first clip is.
  • This makes it possible to connect the elements with each other not only in a connection direction predetermined by the first clips, but also under a direction rotated by 90 ° or 45 ° in particular.
  • a row of overlying elements can be formed, while by connecting the second clip of an underlying complementary half-shell element, a parallel row of underlying elements can be connected.
  • This can be in a particularly simple and quick way to build entire surfaces of (completed to hollow bodies) half-shell elements and lay rationally in concrete layers.
  • a particularly strong connection between the half-shell elements can be produced when the first and the second clips have a different clamping height. Because in this case, a single half-shell element can be connected in two different directions of connection with other same elements without the rods used to interfere with each other. These do not block each other because they intersect at different clamping heights, thus allowing a much stronger integration of each element into a network of bars.
  • the clips can indeed be arranged at any suitable location of the outer surface of a half-shell element.
  • a particularly good handling results when they are mounted in the region of a pole-side flattening of the element.
  • steel strands for example, can first be deposited on the flattened areas of a stored row of half-shell elements and then simply inserted into the clips located there are pressed without the strand slipping off the half-shells.
  • the element can rest on its flattening block-free on the stiffening ribs of another element and is thus stackable in or on this.
  • a hollow body according to claim 18 is particularly simple, reliable and fast and inexpensive to produce in large quantities. Thanks to its air- and water-draining design and its high rigidity, it is also reliable to handle, weather-independent and robust.
  • such a hollow body of two identical interconnected half-shell elements is constructed.
  • Two half-shell elements each having a height of 0.07 m are e.g. suitable for a layer thickness of 0.25 m and elements with a respective height of 0.09 m for a layer thickness of 0.30 m.
  • a particularly fine tuning to different layer thicknesses is achieved by the fact that the interconnected half-shell elements differ in their height. Since the extent of both elements of their respective height is unaffected, their respective connectivity guaranteed. Thus, hollow bodies of almost different shape can be produced. For example, ellipsoidal, hemispherical, lenticular or other half-shell elements can be completed in a wide variety of combinations to form a respective hollow body. A combination of half-shell elements with a respective height of 0.07 m and 0.09 m is suitable eg for layer thicknesses of 0.275 m. At the same time only a small number of injection molds is necessary. Thus, for example, with only three different shapes, a total of six different hollow bodies, with four different shapes, a total of 10 different hollow bodies, etc. can be provided. The technical complexity and thus also the production costs decrease in comparison to the achieved variance in the end product.
  • a tool for producing hollow bodies according to claim 21, which significantly increases their assembly speed of two of the half-shell elements described. This is particularly due to the fact that a half-shell element can be held in a defined position and thus prevented from slipping. For further processing of the hollow body, this may be e.g. be inserted directly into a steel basket in a next step or otherwise connected with other hollow bodies before the next half-shell element is inserted into the receptacle of the tool.
  • the above object is also achieved by a method for connecting hollow bodies claim 23, with the simple and fast individual rows or entire surfaces of hollow bodies can be produced.
  • the length, shape, packing density etc. of these rows or surfaces are in the Compared to rigid steel baskets selectable and limited only by the length of the bars.
  • the handling of the hollow body is thus significantly improved by this connection technology, and always remains guaranteed even under difficult technical requirements.
  • the hollow body should finally be used as a displacement body in a concrete layer, such as e.g. in the production of concrete slabs, walls or ceilings on a construction site in the in-situ concrete method or in a precast concrete plant.
  • the Figure 1A shows a plan view obliquely from above on a half-shell element according to the invention 10.

  • projections 40, 40 'or notches 41, 41' are provided, which engage in complementary notches 41, 41 'or projections 40, 40' of the deferred element 10 and allow accurate positioning of the two elements 10 to each other. In this way, a quick and easy and reliable connection of both elements is possible, which is sure-footed even under construction conditions, ie does not open under load.
  • both a confusion and the delivery of an unequal number of elements 10 are reliably excluded, since the complementary elements 10 are designed the same.
  • the half-shell shape of the elements 10 allows their cost-effective production by injection molding, which requires lower wall thicknesses and thus allows lower material costs.
  • braces 90 ... 90 '''', the star-shaped of its pole P go out. These are simultaneously designed so that they rest against the outer surface of each further element 10 and make this space-saving stackable.

  • the flattening may be stronger or weaker, depending on the intended use of the element 10 in thin or thick concrete layers.
  • the rigidity of the half-shell element 10 is also increased by a shoulder 51 which encloses an indented bottom surface 52.
