Definitions

  • the invention relates to a component with two parallel, mutually made, expanded materials, in particular plastics, especially polystyrene, side walls, and the side walls connecting metallic plate-shaped webs, which are anchored in the side walls by means of projections extending essentially perpendicular to the plane of the plate.
  • a component of the type mentioned is known for example from German utility model 84 22 141.0.
  • the construction. elements are widely used in building construction, especially residential construction, for vertical walls, especially above the ground.
  • the webs of the component must not be made of plastic for reasons of the building police.
  • the webs are therefore designed as double-T-shaped metal profiles, in the mutually facing surfaces of the side walls there are vertical T-grooves, in which the double-T-shaped metal profiles engage.
  • a disadvantage of the known component is that it has only a low bending stiffness, which means that the side walls of a component can be displaced relative to one another.
  • the arrangement of the components is thereby made much more difficult, in many cases it cannot be prevented that a gap remains between the components, which leads to thermal bridges due to the concrete penetrating into the gap.
  • the object is achieved in that further plate-shaped webs connected to the side walls are provided running at an angle to the webs.
  • the bending strength of the component is significantly increased by the interaction of the webs and the further plate-shaped webs arranged at an angle to these webs.
  • the other section interacts, which has just an increased section modulus in the direction mentioned, so that the component becomes significantly more rigid.
  • the plate planes of the webs and the further webs run perpendicular to the side walls of the component, the plate planes of the webs being directed essentially perpendicular to the longitudinal extent of the component and the plate planes of the further webs being directed essentially in the longitudinal direction of the component are.
  • the webs and the other webs should advantageously form an angle of 90 ° to 150 °, advantageously 135 °.
  • the production of the component according to the invention is essentially based on the production of known components, which have metallic plate-shaped webs between the side walls.
  • a trolley is placed in the production mold with supports designed in accordance with the dimensions of the plate-shaped webs.
  • a space remains between the solid core and the manufacturing mold, which will later be occupied by the side walls.
  • the plate-shaped webs project laterally beyond the solid core and protrude into the space between the solid core and the manufacturing mold, so that they are anchored in the side walls of the component after the manufacturing process has ended.
  • a two-part solid core is used to manufacture the component according to the invention, the dividing line between the solid cores being determined by the position of the further web. If the further webs run, for example, in a horizontal line, then the upper surface of the lower solid core and the lower surface of the upper full core likewise run in a horizontal line, and the further webs are received between the two surfaces. If the other webs are arranged at an angle to the horizontal, the corresponding surfaces of the lower and upper core are at the same angle to the horizontal.
  • the formation of a two-part core makes it easy to demold the component produced.
  • the dimensions of the cores depend on the arrangement of the other webs. If the other webs are located, for example, in the middle of the component, the core must be divided in the middle of the manufacturing mold.
  • a web and a further web should advantageously be formed as one component.
  • a web component with the increased section modulus can be produced in a single production process includes the advantages of two web parts.
  • the construction of the component can be significantly simplified by the design of the web and the further web as one component, since significantly fewer components have to be inserted into the core and aligned with respect to the production form.
  • the webs expediently have a rectangular outline, and the other webs are connected to one of the outer edges of the webs.
  • the component shown in Figures 1 and 2 the height, width and length of which is only limited by the given dimensions of the building to be erected and the shaping options, consists of expandable materials, in particular plastics, especially polystyrene, preferably coarse-grained.
  • the component is only shown in one section in the illustration in FIG. depending on the requirements, the component can be extended as long as desired.
  • Perpendicular to the bearing surfaces 1, the component has passages 2 which are delimited by the side walls 4 and by the components 3 connecting the side walls.
  • crossing springs 8 are provided on both side walls 4 and run parallel or perpendicular to the side surfaces 6 of the component.
  • the springs 8 extend parallel to the side surfaces 6 over the entire side wall 4 and perpendicular to the side surfaces 6 from this side surface to the inner surface 17.
  • the component On the opposite bearing surface 1, the component has correspondingly arranged grooves 10, into which the springs 8 each top or bottom intervene adjacent component. Pins 5, which are higher than the springs 8, are arranged at the crossing points of the springs 8 running parallel or perpendicular to the side surfaces.
  • the outer shape of the pins 5 is arbitrary. A square shape with rounded edges is useful.
  • corresponding recesses 9 are provided at the crossing points of the groove 10, which are deeper than the groove 10 and correspond in depth to the height of the pin 5.
  • the passages 2 are filled with concrete, the holes 15 arranged above the components 3 also being filled with concrete.
  • the concrete thus solidifies between the side walls 4 of the components in a cross-shaped structure.
  • the connection of the two side walls 4 of the component takes place via several components 3, which are anchored in the side walls 4.
  • the components 3 consist of a plate-shaped web part 11 and a further plate-shaped web part 12.
  • the plate plane of the web part 11 runs perpendicular to the inner surface 17 of the side edge 4 and perpendicular to the longitudinal extension of the side walls 4.
  • the web part 12 is on the upper edge 13 of the web part 11 fastened and forms an angle of 135 ° with the web part 11.
  • the web part 11 is alternately bent by 90 ° from the plate plane of this web part, which can be seen in particular from the illustration in FIG. 5.
  • the web part 11 has an essentially rectangular outline, with a recess 16 located in the lower region of the web part 11.
  • the arrangement of the components 3 in the component can be seen in particular from the illustration in FIGS. 1 and 2.
  • the front ends of the components 3 protrude into approximately half of the side walls 4.
  • Each of the bent anchoring sections 18 has a length that corresponds approximately to the insertion depth of the component 3 into the respective side wall 4.
  • the web parts 12 protrude into the side walls 4 by the same amount as the web parts 11, but have no bent anchoring sections.
  • the end edge 19 of the web part 12 is provided with two notches 20 which are arranged at a distance and into which reinforcement bars (not shown in more detail for reinforcement) can be inserted.
  • a section 21, which is provided with two holes 22, is also bent out of the web part 11. Reinforcing bars can also be inserted through the holes 22 for reinforcement.
  • FIGS. 6 and 7 show a mold 23 with a solid core 24 for producing a component.
  • FIG. 6 shows a support plate 25 on which a lower part 26 is arranged. Adjacent to the longitudinal side surfaces 27 of the lower part 26 are side parts 28, at a distance from the side part len 28 is supported in the lower part 26 of the core 24. A cover part 29 lies on the upper surfaces of the side parts 28 and the core 24.
  • the upper, outer sections of the lower part 26, which are located between the core 24 and the side walls 28, have springs 8 'and pins 5' corresponding to the design of the springs 8 and the pins 5.
  • the lower surface of the cover part 29 has between the side surfaces 28 and the core 24 corresponding to the grooves 10 and recesses 9 grooves 10 'and recesses 9'.
  • the core 24 is formed in two parts, that is, it is divided in the upper half of the manufacturing mold 23 in a substantially horizontal plane.
  • the division of the core 24 into an upper core 30 and a lower core 31 makes it possible to form the component with the two web parts 11 and 12 which run at an angle to one another, without any non-metallic connection being formed between the two side walls 4 of the component during molding is.
  • FIG. 7 illustrates in a partial section the design of the two cores 30 and 31 for receiving a component 3 between them.
  • the lower core 31 has a slot 32 which extends over the entire width of the core 31, the horizontal extent of the slot 32 corresponding to the horizontal extent of the web part 11, the vertical extent of the slot 32 corresponding to the vertical extent of the web part 11.
  • an inclined receiving surface 33 of the lower core 31 which extends at an angle of 45 ° with respect to the horizontal.
  • Horizontal surfaces 34 adjoin the receiving surface 33 and the side of the slot 32 facing away from the receiving surface 33.
  • the lower surfaces 33 'and 34' of the upper core 30 are designed corresponding to the surfaces 33 and 34 of the lower core 31, but the surfaces 33 and 33 'are slightly spaced apart so that the plate-shaped web part 12 can be received between them.
  • the position of the component 3 with the web parts 11 and 12 results from the illustration in FIG. 6. This figure shows only one Form 23 for producing a component that is not limited in length. Further molds 23 for the production of components can be connected laterally to the production mold 23.
  • the cover part 29 is removed from the production mold 23 and the upper core 23. Then, according to the number of slots 32 arranged in the lower core, components 3 are inserted into this lower core 31. Then the upper core 30 is placed on the lower core 31, the surfaces 33 ′ of the upper core 3 come into contact with the plate-shaped web parts 12. Finally, the space formed between the core 24 and the production mold 23 is closed by means of the cover part 29.
  • the space is filled with expandable material, for example polystyrene, via feed openings, not shown. During inflation, the areas of the components 3 that protrude into the space are anchored in the side walls 4 of the component.
  • the core 24 was referred to as a solid core, in order to express that no expandable material can get into the core during the manufacture of the component, but only the component 3 penetrates the core 24 and thus ensures that only metal is a bridge between the two Forms side walls 4 of the component.
  • the component 3 is expediently designed as a sheet metal part.
