Definitions

  • the invention is based on a method according to the preamble of claim 1 or on a support or column produced by such a method according to the preamble of claim 13.
  • the tubular form of the formwork usually thus the folded spiral-seam pipe or also a pre-cast (filigree) concrete pipe to fix precise height specifications as well as a precise vertical adjustment on an existing ceiling or at least on the foundation of the building to be constructed, which previously required a large number of very complex mounting measures and supports, including the sprouting of the formwork in practically every direction.
  • the folded spiral-seam pipe or also a pre-cast (filigree) concrete pipe to fix precise height specifications as well as a precise vertical adjustment on an existing ceiling or at least on the foundation of the building to be constructed, which previously required a large number of very complex mounting measures and supports, including the sprouting of the formwork in practically every direction.
  • the invention is therefore based on the object to remedy this situation and to drastically reduce the assembly and, as a result, the cost involved in the production of (load-bearing) supports or columns in the construction of buildings and the like, and while maintaining the basic principle of a tubular form of formwork to design them in such a way that one can do without any formings that hold the formwork.
  • the invention solves this problem with the features of claim 1 and the features of claim 13 directed to a device and has the advantages that there is a decisive reduction in the assembly effort of such formwork for columns or supports in building manufacture, that at all without any Bracket or other sprouts, trestles or the like the formwork for the support or column by attaching, for. B. welding or screwing is installed on the respective floor, which can easily be done by two, possibly only by one worker, who are also able to assemble and set up a variety of such formwork during the day.
  • the hollow, tubular formwork forms when the hollow, tubular formwork forms are fixed, they are attached to upright threaded studs in the foot region, preferably with the aid of angle forms, only care being taken to ensure that an exact positioning and adjustment in the vertical is ensured, which can be accomplished, for example, by appropriate washers, wedges and the like.
  • the tubular formwork form By tightening the screw connections or spot welds, the tubular formwork form has a completely adequate, vertically precisely adjusted stability without any further formwork and other aids, so that it is possible to add a steel basket or reinforcement from above, if desired retract and then pour out the pipe.
  • a further particularly advantageous embodiment of the present invention is that the tube is made to length, with an additional adapter piece making high-precision height adjustment possible, so that in addition to the vertical adjustment, the desired height of the column or support can be achieved. and in this respect the floor height - to be specified by a corresponding setting of an adapter between the top and bottom point of the column shape.
  • the formwork tube for the support or pillar can be a common, naturally correspondingly modified spiral-seam tube, a cement tube or some other preform.
  • This leveling of the vertically adjusted formwork tube screwed into the base point defines the reference points (for several columns) for pulling off the in-situ concrete slab with high accuracy, whereby filigree panels arranged between the individual columns or columns can also be used without any problems.
  • the folded spiral tube itself has, for example by means of a suitable flanging that can be produced on automatically working machines, flange-like collar collars projecting outwards at the end regions, which in the foot region of the fastening of the folded spiral-seam tube forming the formwork serve on a support and, for example, mark the lower edge of an in-situ concrete layer to be applied in the head region and, if appropriate, can also be used to attach filigree slabs, other supports and the like.
  • a modified intermediate adapter device is designed so that it simultaneously fulfills several tasks, namely a height adjustment simplified and made possible by a thread engagement for precise vertical adjustment of the pulling level for the in-situ concrete ceiling, and at the same time forms the installation level, i.e. the foot fitting for a subsequent formwork tube form, together with their flanged lower collar.
  • the intermediate adapter device consists of height adjustment rods, which are guided inside in threaded receptacles of the spiral folding tube, in the manner of a screw, and end in end plates, which, with their upper edges, form the level of deduction for the in-situ concrete layer and at the same time enable the fastening of the next spiral folding tube placed on them .
  • the internal thread receptacles for the height adjustment rods can be simple indentations or bruises Be spiral duct; but they can preferably also be formed in the form of bent sheet metal strips, which are riveted to the inner walls at an evenly spaced distance and form hollow passages which have a stamping, so that correspondingly inserted height adjustment rods with an external corrugation in the manner of a screw in these threaded receptacles let it move.
  • the reinforcement cages used in the form of the formwork tube have an upstanding, protruding protruding length that serves as a static embedding length, is guided through the in-situ concrete layer to be applied and extends down to the lower area of the next one adjoining tubular formwork, so that there is a secure static, monostructural unit and strength of a suitably equipped building, with high tensile and compressive strength.
  • tubular formwork form up to a predetermined length in the form of, for example, a spiral seam tube or also a cement tube, with simultaneous automatic, mechanical flanging of the edge edges.
  • an angular flange adapted to the ring shape of the formwork form can again be arranged at the upper end of the folded spiral-seam tube (relates to the first exemplary embodiment), this time threaded sleeves, for example evenly distributed over the circumference, into which threaded rods or rods pointing upwards are screwed, which, with adjustable nuts, support a height, adjustment or setting ring that can be freely adjusted upwards, which then has a surface with a high level of precision for the subsequent in-situ concrete ceiling to be applied specifies which is subtracted.
  • the threaded rod stumps which extend further upwards above the height adjustment ring form the stud bolts for the attachment and the fastening of an upwardly following next tubular form of formwork, so that this can also be fastened and adjusted vertically by simply screwing it tight.
  • the basic idea of the present invention is to dispense with the hitherto required, extremely high expenditure in sprouting and positioning, including vertical and height adjustment of formwork forms for columns or supports, to fix the formwork form itself on a respective building floor, e.g. B. screw or weld - a job that may be carried out in quick succession by a single employee - and, based on such a vertical and fixed in all respects formwork, pour the column with high accuracy, being in an embodiment at the same time by an intermediate adapter device the height level for the subsequent in-situ concrete ceiling layer can be specified, possibly in connection with the creation of a leveled support surface for a next column.
  • tubular formwork form for the creation of columns or pillars in buildings with 10
  • the folded spiral-seam pipe area - or the hollow shape of a cement or concrete pipe that forms the "formwork" for the later pillar - extends in height, for example, to just below the ceiling made of in-situ concrete plus the thickness of the filigree slabs, but leaves at least this distance for the height of the intermediate adapter piece 11 is free, so that corresponding adjustments are possible without problems.
  • the folded spiral-seam tube 12a sits flush on a respective previous floor or the foundation of a building and can be adjusted vertically and in a suitable manner on this floor attached.
  • a preferred possibility for fastening the folded spiral-seam tube 12a is that it has a flange at the bottom, ie in the foot region, with which the tubular column formwork is attached to the floor.
  • this flange is designed as a fastening angle flange 13 and can have a shape as shown in more detail in FIG. 3; it consists of a cylindrical neck part 13a, with which the flange surrounds the lower foot region of the folded spiral tube 12a flush and is also fastened in a suitable manner, for example by corresponding transverse screw connections, welds or the like, and a radial flange 13b preferably attached to the neck part in the one-piece transition below (in a conventional embodiment), with which the folded spiral tube 12a is attached to the floor.
  • the mounting bracket flange 13 has holes 14 corresponding to its circumference, the spacing of which, for. B. threaded stubs emerging from the ground are coordinated and accommodate them. The anchoring of the threaded stumps in the floor will be discussed further below.
  • the folded spiral-seam tube 12a is then open at the top and has an elongated intermediate-level angle flange 15 at its upper end region, which, however, does not correspond to the head part of the tubular form of the formwork, since this head part is formed by the intermediate adapter piece to be explained, with the only difference that that instead of the holes 14 extending over a predetermined height threaded bushings 16 are provided, preferably also distributed uniformly over the circumference, at least three, but usually four such threaded bushings are provided.
  • the intermediate-level fastening angle flange 15 is also fastened to the upper end region of the folded spiral-seam tube 12a by suitable fastening means, for example welding, transverse screwing or the like.
  • Spacers preferably in the form of threaded rods 17, extend upwards from this intermediate-level fastening flange 15, which are screwed into the threaded bushings 16 of the intermediate-level angle flange and, as the upper connection, jointly support a ceiling-level element, preferably in the form of a simple flat head ring 18, as shown in plan view in Fig. 2 again.
  • this head ring 18 has bores 19 through which the ends of the threaded rods pass - by lower adjusting nuts 20, which are screwed onto the ends of the threaded rod first, the head ring 18 can, as can be easily seen, be adjusted in height , since it is easily possible to adjust the adjusting nuts 20 so that with high or highest accuracy - if one uses optical setting devices, for example - with the larger number of available Columns all head rings are set by manipulation of the nuts 20 so that there is a perfect pull-off level for the leveling corresponding to the top edge of the head ring of the next ceiling to be subsequently applied in the form of in-situ concrete.
  • the threaded rods 17 are dimensioned in length so that they extend a further distance beyond the top ring top edge as a later in-situ concrete ceiling level, and so at the same time again form the threaded stumps required further ahead for the attachment of the next spiral duct , which is designated in Fig. 1 with 12a '.
  • the half-shell 21 can thus consist of a lower pot base 21a with the (central) cutout for the passage of the spiral-seam tube or its intermediate level fastening flange and of an upwardly extending one Ring cylinder 21b, on the upper edge of which filigree plates 22 adjoining one or both sides can advantageously immediately lie, which are preferably used for the production of (intermediate) ceilings from in-situ concrete when building, as is known per se.
  • support and support means can also be provided here, but in this respect not the positioning and arrangement of the support or their formwork form, but hold the filigree panels 22 accordingly.
  • Such support means can be timbers, sprouts, intermediate punches, crossbeams and the like, which are indicated in the drawing in FIG. 1 and denoted overall by 23.
  • the rest of the procedure can be such that, for example, before attaching the threaded rods 17 in the threaded sleeves 16 of the intermediate level fastening angle flange 15, a reinforcement cage indicated at 24 is lowered into the tubular cavity of the folded spiral tube 12a which is open to the top, and which can also be lowered to can extend upwards to the height or in the area of the on-site concrete to be applied later - afterwards, each of the folded spiral-seam pipes, which are also available in large numbers, can be filled up to the intermediate level with concrete on site, which is then hardened; this gives these "partial supports" a high stability with already existing high-precision vertical adjustment; Subsequently, the manipulations already described above can be carried out without any problems, namely attaching the threaded rods, laying on the filigree panels, possibly using half-shell formwork and the like.
  • such a concrete ceiling can easily be pulled off using the existing (multiple) orientation level points corresponding to the top edge of the top ring, and once the local cast concrete has solidified, work can be continued immediately by re-attaching the base point mounting angle flanges to the threaded stumps 17 of the threaded rods 17 that stand upwards of the next generation of formwork for supports or columns, adjusted vertically and then further processed.
  • a simplified and therefore particularly advantageous variant of the present invention consists in the fact that, with preferred retention of a spiral-seam tube as formwork for a reinforced concrete column to be created, the spiral-seam tube 12a ', preferably one at its two end points has externally projecting ring flange forming flanges, which are referred to below as the upper collar 25a or lower collar 25b.
  • the lower collar collar 25b serves, comparable to the lower fastening angle flange of the first exemplary embodiment, to rest on lower supporting elements of a respective previous column structure, more precisely a height adjustment intermediate adapter device formed by the upper head region of the previous column structure.
  • the folded spiral-seam tube 12a ' has internal receptacles 26 which are used for the threaded positioning of threaded rods, screw bolts or height-adjusting means 17' and can be designed, for example, in a particularly simple manner in the form of pinches of the spiral-seam fold tube or in the form of sheet metal angles riveted on the inside, for example in a triangular shape, which have one or more indentations pressed inwards, so that these sheet metal angles, of which a possible embodiment is shown in FIG.
  • the plates 28 then simultaneously form the flat contact points for the next column formwork, i.e. for the subsequent subsequent folded spiral-seam tube 12a ′′, which, as the plan view of FIG. 6 shows, with its lower flanged collar 25b onto the head plates 28 the height adjustment rods 17 'are attached and attached to them, for example by welding to the outwardly projecting ring segment 28a of each plate.
  • each height adjustment rod 17 'with the end plate 28 carried by it ensures that at the same time the next following tubular formwork form is precisely aligned vertically; should adhere to this, possibly due to deformations during transport or the like, inaccuracies in the lower collar surface result, then the vertical adjustment can easily be carried out by means of some washers, whereupon the collar can be attached to the plates 28 of the intermediate adapter device thus formed by welding spots.
  • the intermediate adapter device formed from the height adjustment rods 17 'with upper end head plates, which are operatively connected to inner receptacles of the folded spiral tube, simultaneously forms precise pull-off points for an in-situ concrete cover layer to be subsequently applied as an auxiliary gauge and furthermore the installation points for the subsequent pipe formwork realize.
  • the respective center of the formwork tube can also be easily determined by means of a suitable gauge, and then , starting from this, mark the set-up lines for the collar of the following folded spiral-seam tube on the plates 28.
  • a further advantageous embodiment consists in that, as already mentioned above, by introducing a reinforcement cage 24 ', the static and dynamic strength against the effects of tension and pressure can be decisively increased, with an overlap of the respective reinforcement cages being particularly preferred from one another being vertically overlapping Pillars one So-called static integration length is guaranteed, through which considerable tensile influences can be absorbed.
  • a first steel frame which is inserted into the lower spiral folding tube 12a 'in FIG. 4 and forms a reinforcement cage, extends beyond the upper end of the plates 28 carried by the height adjustment rods 17' into the lower region of the subsequent spiral folding tube 12a '', in order to avoid the plates, corresponding steel or iron reinforcing bars can run cranked inwards.
  • the formwork for the in-situ concrete ceiling can be made by means of lower filigree plates 22 ', which are arranged in the usual way.
  • the upper collar 25a can be used as a closure or as a support element.
  • a screed layer 30 applied to an intermediate insulating layer 29 can still be seen.
  • Fig. 5 shows in an enlarged view the threaded rod forming the height adjustment rod 17 'with an upper plate-shaped end plate 28 and the preferred ones Welding area 31 between the protruding plate segment and the lower flanged collar of the folded spiral tube 12a '.
