Definitions

  • the invention relates to a self-supporting composite building board for raised floors, ceilings, roofs or the like, with a tub serving as external reinforcement made of a material with high tensile strength and high modulus of elasticity, preferably sheet steel and a filler material with low tensile strength and low modulus of elasticity, e.g. Anhydrite or concrete in the cavity of the tub, also with thrust anchors in the tub bottom, preferably in the form of funnel-shaped openings, further on a method for producing such composite building boards.
  • a tub serving as external reinforcement made of a material with high tensile strength and high modulus of elasticity, preferably sheet steel and a filler material with low tensile strength and low modulus of elasticity, e.g. Anhydrite or concrete in the cavity of the tub, also with thrust anchors in the tub bottom, preferably in the form of funnel-shaped openings, further on a method for producing such composite building boards.
  • Such a composite building board is known from DE-PS 2004101.
  • the tub serving as external reinforcement is usually made of sheet steel in a square shape by deep drawing, the essentially flat tub floor merging into vertical walls on all four sides.
  • To stiffen the tub base it is also known to impress flat, cross-shaped beads in this.
  • deep-drawn tubs are relatively expensive to manufacture and, in addition, deep-drawing and the static conditions on the finished composite building board require fairly thick-walled sheets for the tubs, which further increases the costs.
  • the static neutral zero level in this known composite building board is only a relatively small distance above the trough bottom in the filler material with low tensile strength and low modulus of elasticity.
  • From DE-AS 21 59 959 is already known as a reinforcement for a concrete composite slab formwork sheet made of sheet metal (lost formwork), which is anchored in the concrete, parallel webs with different cross-sectional shapes, which the formwork panel a sufficient for installation Give moment of inertia and resistance.
  • these constructions are not readily based on self-supporting composite Building boards of the type described at the outset can be transferred with external trough-shaped reinforcement.
  • this object is achieved in that the trough is assembled with strip-shaped profile parts of any dimensions and on the underside of the trough bottom, piles of the tensile material are provided in the form of parallel, perpendicular or approximately perpendicular downward, rigid webs or ribs.
  • Another embodiment of the invention is characterized in that both two opposite side walls of the tub, as well as the tub bottom with the lower rigid webs consist of one piece.
  • This cross-sectional shape can e.g. by roll deformation of a corresponding strip material, and to complete the tub, you then only need to attach two front side walls of the tub.
  • a very economical process for continuous Manufacture of tubs for self-supporting composite building boards according to the invention is disclosed in claim 8.
  • a particular advantage of this method is that a tub body, consisting of the tub floor and at least two downwardly rigid webs or ribs made of strip material (sheet metal strip) can be produced in a continuous working process by roll deformation. It is essential that gutter-shaped sheet-metal sections of different lengths are to be produced with a constant cross-sectional profile, which can be added laterally as required. In this way, tubs for composite panels of different lengths and widths with a rectangular plan can be easily manufactured in flow production.
  • the various work processes can be connected in series without manual intermediate transport in flow production and thus without loss of time.
  • the composite building board 10 shown in FIG. 1 and corresponding to the prior art contains, as external reinforcement, a rectangular trough 11 made of sheet steel and manufactured by deep drawing, the cavity of which is filled with a filler material 12, for example anhydrite.
  • a filler material 12 for example anhydrite.
  • the anchor between the pressure-resistant filler material 12 and the tub 11 from train Solid material takes place essentially through funnel-shaped openings 13 in the trough base 14, which protrude from the inside of the base, protrude into the filling material 12 and are filled by the latter.
  • These funnel-shaped openings 13 form so-called thrust anchors.
  • statically neutral plane N in the pressure-resistant filler material 12 lies only with a very small distance “az” above the trough base 14 and thus somewhat above the tensile force Z effective in the trough bottom 14 when the composite building board 10 is loaded.
  • lever arm which corresponds to the distance az
  • this plate construction can not be produced economically with correspondingly large dimensions to bridge larger spans.
  • a shape is now selected according to the invention such that the outermost, tensile material fibers of the outer trough-shaped reinforcement and thus the resultant from the sum of the tensile forces have a distance az that is several times greater from the neutral plane
  • N has
  • the composite building board 10A of the first exemplary embodiment of the invention corresponding to FIG. 2 has a trough 11A as external reinforcement for the pressure-resistant filler material 12, for example anhydrite.
  • the basic body of this tub 11A consists of a single strip-shaped profile part, which is brought into the cross-sectional shape shown in FIG. 2 by rolling or roll deformation.
  • This one-piece trough base body contains the trough bottom 14 provided with funnel-shaped openings 13, of which along two opposite outer edges of the Rigid webs 15 extend vertically downwards. These rigid webs 15 are folded at R at the same distance from the underside of the tub floor by 180 ° and then run upwards, the parts projecting upward above the tub floor 14 forming two opposite side walls 16 of the tub 11A.
  • the walls of the tub 11A, which cannot be seen in FIG. 2, on the end faces of the tub basic body can be designed, for example, in the manner shown in FIG. 6B, in which a corresponding wall 170 made of a strip-shaped sheet metal material with angled tabs 180 is shown , by means of which the wall 170 can be attached flush to the side walls 16 (inside), for example welded or screwed on or riveted on.
  • the funnel-shaped openings 13, which stand up from the inside of the trough bottom 14, are in the filling material 12, e.g. Anhydrite embedded, which also fills the cavities of these openings, which thus serve as a thrust anchor between the external reinforcement and the filler material in this and also all subsequent exemplary embodiments.
  • the filling material 12 e.g. Anhydrite embedded
  • statically neutral zone N lies in the region of the trough base 14 and the distance az between the resultant Z of the tensile forces and the neutral zone N is a multiple of that in FIG hence their resilience.
  • the tub 11A serving as external reinforcement can be made of very thin-walled sheet metal stand. It is assumed that the thickness D of the V ER- bundbauplatte 10A equal to that of composite plate 10 of FIG. 1 and the same sheet quality is used.
  • the composite building board 10B contains as external reinforcement for the pressure-resistant filler material 12, e.g. Anhydrite a trough 11B, which consists of several strip-shaped profile parts from e.g. Steel sheet composed.
  • the trough bottom 14 with the funnel-shaped openings 13 is formed here by the bottoms of a plurality of, reversely arranged, trough-shaped sheet-metal profile pieces 17 which are of the same length and are connected flush with one another on their downwardly projecting, abutting legs. This can be done by roll seam or spot welding, screwing or riveting.
  • the trough 11B accordingly has a multi-part trough base 14, and the lateral delimitation of the trough cavity for accommodating the filler material 12 can be achieved either by a frame made of C-profiles 19 or flush with the top of the trough base 14 or a frame made of C-profiles 20 exist, which are attached to the outer legs or webs 18 of the trough-shaped sheet metal profile pieces 17.
  • the C-profiles 20 also completely overlap the end faces of the trough-shaped sheet-metal profile pieces 17.
  • the sealing of the joints between the individual parts of the tub 11B can e.g. simply by means of adhesive strips in order to prevent the filler material 12 introduced in the flowable state from escaping, e.g. Avoid anhydrite.
  • the composite building board 10C has a trough 11C as external, horizontal reinforcement for the filler material 12, for example anhydrite on, which is composed essentially of the same components as in the embodiment of FIG. 3.
  • the inverted trough-shaped sheet-metal profile pieces 17 are provided with outwardly projecting strip-shaped flanges 21 on their legs or webs 18 which stand down.
  • the trough-shaped sheet-metal profile pieces 17 are connected to one another, while the frame composed of the C-profiles 20 is attached to the outwardly projecting flanges 21 of the outer legs or webs 18 of the trough-shaped sheet-metal profile pieces 17.
  • cavities are formed between adjacent downward legs on the one hand and the outer legs and the opposite C-profiles 20 of the circumferential frame on the other hand, which are also filled by the filler material 12.
  • a frontal outflow of the filler material when it is introduced into the trough 11C is prevented by the C-profiles 20 (not shown in FIG. 4) of the surrounding frame arranged on the front side.
  • FIGS. 6A-6C show, by way of example, how the end of the tub cavity can be closed, for example in the case of the composite building board 10B in FIG. 3, right half.
  • FIG. 6B illustrates the one end wall 170 before it is inserted into the C profiles 19.
  • a similar wall 170 is provided at the end face of the tub 11B.
  • the walls 170 can be fixed flush by means of their angled tabs 180 on the inside of the C-profiles 19 by spot welding, screwing or riveting, so that one is closed on all four sides, at the top receives open tub 11B with the tub floor 14.
  • 6C shows the one front end of the tub 11B after the wall 170 has been inserted.
  • all the joints between the individual parts of the tub 11B can be provided, for example, by adhesive strips or else, for example plastic seals be sealed medium that can be inserted between the individual parts when assembling them.
  • the two end walls of the tub 11B are formed by a part which is angled away from the tub floor 14 and consequently connected to it in one piece. Since the trough base 14 in this version consists of the two channel-shaped sheet-metal profile pieces 17 arranged in reverse, it is necessary here to protrude from both floors of the channel-shaped sheet-metal profile pieces accordingly (indicated in FIG. 6A at one end of the channel-shaped sheet-metal profile pieces 17 in dashed lines), bend upwards.
  • the lateral boundary of the trough cavity is consequently formed in the exemplary embodiment according to FIG. 6A by the opposite side walls 19 made of C profiles and the two opposite walls 171.
  • the tubs 11A-11D are filled with a flowable or pourable, hardenable filler material, preferably anhydrite, after completion, with an excess of filler material.
  • a flowable or pourable, hardenable filler material preferably anhydrite
  • This excess filler material is then pressed outward through the openings 13 and / or removed by wiping, the filler material being brought to the level of the tub.
  • the filler material is then allowed to harden. This hardening process can be accelerated by applying heat.
  • the funnel-shaped openings 13 acting as thrust anchors in the trough base 14 transmit the horizontal thrust forces between the trough base 14 and the filler material 12.
  • tubs 11A-11D can be constructed with outer edges of equal length for the production of square composite building boards, they are due to their Construction from strip-shaped profile parts with rigid, parallel webs on the trough floor particularly suitable for rectangular floor plans, whose length dimensions are larger than their transverse dimensions.
  • FIGs 7 and 8, 9 and 10 each show a F ER- actuation system shown schematically, by means of of a ribbon material, for example sheet steel, channel-shaped continuous, provided with openings 13 metal profile pieces 17 can be prepared, each added laterally alone or form the tub floor 14 with vertically downwardly rigid webs 18 (FIG. 3).

  • two transport rollers 32, 33 are used, between which the band material 30 with the angled legs 18 'runs along the longitudinal edges (as a channel-shaped profile).
  • This transport rollers 32, 33 is followed by a punching device 34 in the direction of movement of the channel-shaped profile, which is moved back and forth in the axial direction of the strip material 30 or channel-shaped profile.
  • a punching device 34 in the direction of movement of the channel-shaped profile, which is moved back and forth in the axial direction of the strip material 30 or channel-shaped profile.
  • the funnel-shaped openings 13 in the bottom of the trough-shaped profile are punched out by punching dies 35, of which only three are shown by way of example in FIG. 7.
  • the punches 35 work together with a die 36 which is arranged below the channel-shaped profile and which runs back and forth with the punches 35 accordingly.
  • a foil 37 for example aluminum foil, is glued onto the bottom of the trough-shaped profile between the legs 18 'and is pulled off a roller 38.
  • the film 37 is before the merge tion sprayed with the channel-shaped profile by a spray device 39 with adhesive.
  • the film 37 provided with adhesive is pressed against the bottom of the channel-shaped profile by a pressure roller 39.
  • the pressure roller 39 works together with a counter pressure roller 40, which is provided with recesses 41 for receiving the funnel-shaped openings 13.
  • This film 37 serves, inter alia, to close the funnel-shaped openings 13, so that later, when the channel-shaped sheet metal profile pieces 17 form the tank bottom 14, the leakage of the liquid F ülltechniks is prevented by the tub bottom therethrough.
  • this film 37 can also be used to increase sound insulation and / or fire protection in the finished composite building board.

  • the trough-shaped profile pieces 17 obtained in this way are then turned and can be arranged individually or in a plurality side by side and connected to one another at their legs to form the trough base 14 with the rigid webs 18 projecting downwards (FIG. 3).
  • the production plant shown in FIG. 9 for trough-shaped sheet-metal profile pieces 17 for forming trough bottoms 14 essentially corresponds to that of FIG. 7 with the exception that the funnel-shaped openings 13 in the bottom of the trough-shaped profile are produced by two rotating rollers 43, 44, between which the channel-shaped profile runs.
  • One, e.g. upper roller 43 is provided with preferably interchangeable mandrels 45, while the other, e.g. lower roller 44 contains depressions 46 which cooperate with the mandrels 45 during the rotation of the rollers, with rotating rollers 43 and 44 the mandrels 45 penetrate into the trough-shaped profile moving in the direction of the arrow and produce the openings 13, as shown in FIG. 10 is indicated schematically.
