Definitions

  • the invention relates to a cement board or the like with reinforcing inserts made of fibers located near one or near the two board surfaces, and to elements formed by such cement boards.
  • the invention also relates to a method for producing cement slabs and to an apparatus for carrying out the method.
  • the company has already started to produce fiber-reinforced cement boards. Two possible paths have been followed in this direction: firstly, the entire volume of the cement board can contain more or less statistically distributed short fibers, and secondly, the board can be provided with one or more mat-like reinforcing inserts, at least to a certain extent Degrees absorbs tensile forces.
  • Typical of the first category are the asbestos-cement boards, in which asbestos fibers are embedded in the cement mortar. Even though the fibers contribute to an increase in the bending tensile strength, the asbestos cement boards have a serious disadvantage in that their breaking strength and impact resistance are not sufficient, which makes these boards very sensitive to dynamic stress. Asbestos fibers are also known to be harmful to health, and inhalation of these fibers can lead to serious lung diseases to lead. The production of asbestos cement slabs is therefore extremely problematic.
  • the plate according to CH-PS 59 03 79 (in particular column 3, lines 40-50) is typical of the second category.
  • reinforcement mats made of short glass fibers are used as reinforcement inserts for cement slabs.
  • an area-covering silvering insert is provided near the two surfaces of the cement board.
  • the individual short fibers are largely statistically distributed in the mat, being intertwined with one another in such a way that they form the mat.
  • a cement board is now to be created, which is reinforced with reinforcement inserts made of glass fibers located near one or both of the plate surfaces and in which the reinforcement inserts are used and designed such that the plate has a desired high flexural strength with a significantly lower fiber content, one Compared to asbestos cement boards, it has significantly better impact resistance and can also be processed as required ten, for example, can be nailed.
  • the reinforcing insert is a grid which is formed by intersecting glass fiber bundles, the glass fiber bundles consisting of continuous fibers arranged in the longitudinal direction.
  • the invention makes use of the knowledge that the reinforcement insert used hitherto cannot be completely penetrated by the cement mortar or is not optimally embedded in the cement mortar because of its surface-covering mat-shaped structure formed by interweaving the statistically distributed short fibers.
  • the mat in the tensile zone is only able to absorb the existing tensile forces to a limited extent and ensure the stability of the plate under bending tensile stress. Because of the deviations of the "uncontrollable" short fiber in relation to the main torque directions, there is also a reduction in the structure when the known mat-reinforced cement board is stressed.
  • Another important aspect of the invention is the fact that short fibers are not used. If the known cement board based on short fibers breaks, it can be observed that the fibers are "pulled out" of the cement mortar. So there is no tearing of the short fibers, ie their strength remains largely unused. In contrast, in the invention, continuous fibers are used, each of which forms a bundle of glass fibers. With a plate constructed in this way, the fibers cannot be pulled out of the matrix and the plate does not break until the tensile strength of the fibers is overcome and the fibers tear sen. This means that the tensile strength of the fibers is fully exploited here.
  • the lattice structure with the intersecting endless glass fiber bundles has the advantage that the tensile strength is increased in all directions of the plate plane, which is not the case, for example, with the asbestos-cement plates mentioned at the beginning.
  • Another advantage of using infinite fibers is the fact that this gives the panel optimum elasticity and increases its impact resistance.
  • the glass fiber bundles used in the invention from continuous fibers arranged in the longitudinal direction or the grids formed therefrom can be produced in a simple manner and are therefore available as a mass product. They meet the requirement that their modulus of elasticity be greater than the modulus of elasticity of the cement matrix, and they allow this fact to be used optimally.
  • the glass fiber bundles can be normal glass, but then, as is known per se, they must be protected against corrosion due to the high pH value of the cement stone by coating the bundles with synthetic resin, in particular polyester resin .
  • the glass fiber bundles can also consist of a special glass that is resistant to cement.
  • sheathing of the bundles can be omitted, which has the further advantage that the glass fiber bundles can also be biased in the direction of one or both axes of the grid.
  • This is not possible with coated bundles, because the glass can hardly be preloaded into the cement matrix due to the coating.
  • the prestressing of the glass can be transferred almost completely to the cement matrix, which results in a considerable additional increase in strength (analogous to prestressed concrete).
  • the cement board according to the invention also has the advantageous property that it can be nailed. It assembly is possible and the cut panels can easily be attached to ceilings, walls, etc. with nails.
  • a plurality of ribbed plates are built up vertically on a base plate formed by the new cement plate.
  • the rib plates also have at least one grid, which extends not only near the two parallel surfaces, but also near the surface of the upper edge facing away from the base plate.
  • the element can also be built up so that a second base plate is used. Between the two parallel base plates are the rib plates, through which the base plates are connected to a unit.
  • This construction of a double-walled plate is characterized by a particularly high stability.
  • the invention is also intended to provide a method for its production create, which is based on the procedural steps that first a first (prestressed or not prestressed) mesh is placed on a base, then poured onto this mesh or on the base of highly flowable grout or cement paste, and then the base is set in shaking movements .
  • the mortar used is given an appropriate consistency.
  • the mortar must be free-flowing, on the other hand, it should not separate when flowing. This can be achieved by choosing an appropriate grain size distribution for the aggregate, by adding liquefiers (e.g. a sulfonated melamine-formaldehyde resin) and by adjusting the water solids value. Standard sand as well as light aggregates or a mixture of both can be used as aggregates.
  • a frame is attached to the base, the dimensions of which are adapted to the size of the desired cement board and which is advantageously designed as a plug-in frame, the four frame sides of which open in openings on the flat base are pluggable.
  • this is provided with a hydrophobic layer, for example in the form of a PVC plate or coating.
  • a second grid can be inserted from above. You can push this grid in a little by hand or using an appropriate tool (e.g. a rubber-coated roller). However, it is also possible to cause the penetration of this grid by the shaking movements which "lift" the first grid.
  • the two grids When the cement mortar has solidified, the two grids have their desired position near the two surfaces of the cement board, with sufficient coverage.
  • reinforcing inserts with a lattice structure thus not only enables particularly good values for the bending tensile strength, impact resistance of the cement board, but also the problem-free and rapid production of the cement boards according to the invention is also characterized by great simplicity.
  • the length of time during which the underlay is exposed to the shaking movements depends, of course, within certain limits on the thickness of the cement slab to be produced and the consistency of the mortar. It has been shown that with thin cement slabs, the thickness of which is between 0.5 and 1 cm, a short period of time of only about 30 seconds is completely sufficient. The actual manufacturing process of a cement board therefore takes surprisingly little time.
  • cement plates can also be produced easily and simply by inserting the ribbed plates into the not yet solidified grout, to a depth just before the neighboring grid of the cement plate, which forms the base plate.
  • a shape that is closed on all sides except for the upper surface is used, the dimensions of which correspond to the size of the desired ribbed plate.
  • a grid is inserted into this form, the ends of the grid protruding from the form by a finite amount at the top.
  • at least one U-shaped spacer can be inserted into the mold before the cement mortar is poured into the mold.
  • a ribbed plate produced in the manner described thus has a continuous reinforcement insert in the form of the grid near three surfaces.
  • the latter protrudes somewhat with its two ends from the upper edge of the ribbed plate. With this edge, the ribbed plates are inserted into the not yet solidified grout after the free ends of the grid are bent sideways, so that in the finished state they run approximately parallel to the surface of the base plate.
  • a vibrating table can also be used in an advantageous manner in the production of the ribbed plates as described, so that air can escape from the mold and smooth surfaces result.
  • a favorable positioning of the grid is also achieved here by the shaking movement, and here too this movement is preferably directed upwards and downwards.
  • the cement plate 1 shown in partial side view consists of cement mortar 2, preferably highly flowable casting mortar, in which a grid 4 1 and 4 "is placed near the two surfaces of the cement plate 1.
  • the structure of a grid 4 can be seen in FIG. 2 of intersecting glass fibers 6, each glass fiber bundle being made up of ordered continuous glass fibers 8.
  • the glass fiber bundles 6 - as can be seen in FIG. 3 - are made of synthetic resin 7, Because of the net-like structure of the grid 4, this can absorb tensile forces not only in one direction, but in all directions.
  • FIG. 4 shows a schematic representation of a vibrating table 16 for the production of the cement slabs 1.
  • the vibrating movement which takes place in the vertical direction, is indicated by the two arrows A and B.
  • a laterally directed movement can also be superimposed on this movement.
  • Conventional vibration devices can be used for the drive.
  • the vibrating table 16 comprises a flat table surface 10 on which a hydrophobic base in the form of a PVC plate 14 is applied.
  • the closed frame 12 defines the outer shape of the cement board 1 to be produced, and different sizes can be realized in a simple manner by replacing the frame 12.
  • the frame 12 is designed as a plug-in frame, the four frame sides of which are provided at the bottom with pins which are inserted into openings (not shown) in the table surface 10. According to the arrangement of the openings mentioned, different dimensions can now be realized in a simple manner.
  • the side walls of the plug-in frame are also made hydrophobic on their inwardly facing surfaces, so that no formwork oil is required.
  • the lower grid 4 1 is first placed on the hydrophobic PVC plate fourteenth
  • the highly flowable cement mortar is poured into the space formed by the frame 12.
  • the air escapes from below, so that there is a smooth surface on the side facing the PVC plate.
  • a plate thickness of approximately 0.5 to 1 cm it is sufficient to leave the vibrating table 16 switched on for about 30 seconds.
  • the other grid 4 is then embedded in the cement mortar 2 from above, which can optionally be done by hand.
  • the highly flowable grout 2 is expediently light aggregates, e.g. Expanded pearlite, added when it comes to reducing the bulk density of the plate.
  • a base plate 20 formed by a cement plate according to the invention is provided with vertically arranged rib plates, as a result of which the bending tensile strength can be increased to a significant extent if one considers the same cross sections.
  • the double-walled element 18 1 according to FIG. 6 two base plates 20 and 28 are provided, between which the rib plates 22 extend. This element 18 1 is characterized by an even better stability.
  • the reinforcement ribs 22 are produced in a manner similar to that already described with reference to the cement plates. 7, a grid 24 is first inserted into a mold 30 which is only open at the top. The grid 24 is formed in one piece and protrudes somewhat with its two ends 26. In order to ensure the desired position of the grid near the surfaces of the future ribbed plates, a spacer 32 (cf. FIG. 9) can be inserted into the mold 30 at intervals. Thereafter, the cement mortar 2 or the grout is poured into the mold 30 in a conventional manner. When the cement mortar has solidified, the mold 30 can be removed, whereby the ribbed plate 22 is completed. The ends 26 of the grid 24 mentioned protrude freely from the ribbed plate in front. This is done deliberately in order to improve the fastening of the rib plates 22 on the base plate 20.
  • the rib plates 22 are pressed slightly into the not yet solidified cement mortar 2 of the base plate 20 with the free ends 26 of the grid 24 downward.
  • the ends 26 of the grid 24 thus assume the shown approximately parallel position to the grid 4 ".
  • a common grid 24 ' can be used for several rib plates at the same time. to be used, which is placed in the juxtaposed molds 30. After the cement mortar poured into the molds 30 has solidified, the area of the grid 24 'between the individual molds can be separated again, which would result in the free ends 26 already described but also possible to maintain the common grid 24 ', which would then extend in the element 18 according to FIG. 8 between two adjacent ribs 22 parallel to the other grid 4 ".
  • the element 18 shown in Fig. 5 can also be manufactured in a single operation, e.g. after the cement mortar has been poured into the molds 30 according to FIG. 10, the grid network 4 "is placed on it, and then the cement mortar 2 of the base plate 20 is poured in - using a frame according to FIG. 4. Finally, the further grid network can then be added 4 'are embedded, and after the cement mortar has solidified, the element 18 according to FIG. 5 results.
  • the bending tensile strength is 5-12 MN / m 2 .
  • grids consisted of glass fiber bundles made of normal, non-alkali-resistant glass and therefore had to be encased in a resin.
  • grids whose glass fiber bundles consist of a special, sufficiently alkali-resistant glass, such a sheathing is no longer necessary. This makes it possible to embed the grids in the cement matrix with a direct cement-glass bond, and this in turn leads to the advantage that the glass fiber bundles can then be prestressed in one or both directions of the grille.
  • Prestressing the glass fiber bundle is only useful if there is sufficient cement-glass bonding. It increases the tensile strength of the cement in the respective clamping direction matrix again, and not insignificantly. It is generally sufficient to prestress only one of the grids 4 1 or 4 "provided in the cement slab 1, since a single slab is normally only subjected to bending in one direction after assembly and consequently only has to have increased tensile strength on one side thereof
  • the second grid has the primary function of stabilizing the plate during transport, where changing bending directions are unavoidable, and would otherwise be superfluous (apart from securing the "right" sides of the plate from being mixed up) 5 and 6 is sufficient one-sided bias of the grids located in the cement slabs.
