Definitions

  • the invention relates to a perforated profile bar made of metal, which is suitable for the production of support and support structures of any kind and also of barriers and borders.
  • a toy construction kit has long been known, which contains perforated flat, angle and U-shaped bars together with perforated plates, elbows, etc. and screws, and something similar will soon be available, only correspondingly larger and stronger in all areas Production of storage racks in storage rooms came into use.
  • Common characteristic is a single-row perforation per profile side, so that crossing or branching profile bars can only be connected with a single screw; this means that the connection can only be loaded to a very limited extent and, above all, it is not stable in terms of angle. To remedy the latter, must you insert angle plates into the connection and additionally screw them with both profile bars, or you have to provide additional profile bars as struts, e.g.
  • a support for supporting formwork the profile of which has essentially the shape of a U with legs of unequal length; one leg is angled inwards and struts at regular intervals with the other, and only elongated holes are provided for the passage of load-bearing screws, namely in only one row in the legs and in three rows in the web, together with various small holes for nails and wood screws for fastening the formwork wall.
  • the elongated holes of the three rows in the web and the one in each leg are longitudinal, not longitudinally offset from each other and in each row the same width, in adjacent rows of different widths.
  • This carrier too, is not suitable for applications other than this special support structure, for example for the production of the most varied and also exposed to high loads, for the following reasons, among others.
  • Two such intersecting beams can only be screwed together if they abut each other on the web side, and then not in any position and not at any angle because of the arrangement of the elongated holes.
  • the thighs fall for one Such a connection should be disregarded because it would not be angularly stable because of the single-row arrangement of the elongated holes, ie connectivity with only one screw, and the side facing away from the web is unsuitable for a connection simply because of the unequal leg lengths.
  • connection "web against web" - at angles that allow at least two screw connections - would be useful, because because there are only closely adjacent elongated holes available in a minimal number and of different widths, it would be pivotable and movable under the influence of a load. Of course, tightening the screws might not help. Moving or swiveling, ie giving in at a connection point of a supporting structure would result in overloading at other points, ie the bridge or the scaffolding would collapse the next time it is loaded.
  • the inventor has freed himself from the traditional view and has set himself the task of creating a perforated profile rod of the type mentioned, which can be used universally by branching from it with a second, similar, which is attached or inserted to it crosses it on one of its sides at any angle, without further ado can be directly connected to at least two screws guided by covering holes in such a way that the connection, except in the context of the essential play of the screws in their holes, is neither displaceable nor pivotable under the action of a load.
  • connection should neither be displaceable nor pivotable under the action of load ensures that it can also be used for highly stressed support and support structures and precludes the known exclusive use of elongated holes, with which the other conditions would often be met without that one would have to make special considerations about the arrangement of the elongated holes.
  • support and support structures made with the new profile bar should really be resilient, it is essential that they are provided with round holes; However, this does not exclude that a part of the round holes is replaced by elongated holes, whereby only the advantages of the latter are taken over and stable connections at any intersection angle are made possible even with larger hole spacings than with the exclusive use of round holes.
  • connection of the new profile bar with a similar second, crossing it is in any case not displaceable if at least one screw is passed through a round hole in each of the two profile bars; They cannot be pivoted about this connection even if only one further screw is passed through an elongated hole in each of the two profile bars, provided that the longitudinal axis of neither of the two elongated holes is tangent to a circle around the former connection as the center. For manufacturing reasons alone, elongated holes will then be arranged either lengthwise or crosswise and not be curved.
  • the former connection closes a movability even if the screw is only passed through a round hole in one profile bar, in the other, crossing it through an elongated hole, provided that this is transverse to the load direction or receives the screw at the end against which it is pressed by the load.
  • the crossing profile bar cannot be swiveled around this connection in relation to the other, even if only one further screw is passed through an elongated hole in each of the two profile bars, provided that the longitudinal axis of neither of the latter two elongated holes lies tangentially to a circle around the former connection.
  • a preferred embodiment of the new profile rod is that its profile consists of a web and two flanges, that it is symmetrical to the axis across the web through the middle, and that it is inscribed in a rectangle, with at least the outer limits of the flanges with each a side of the rectangle coincide, the length of which is equal to the flange width. It is advantageous if the height of its profile in the web direction is an integral multiple of its flange width, in particular twice as large. Then two such profiled bars can be brought into contact with one another on all sides, and are two of them as wide as one in the other, so that they can be combined with one another in a variety of ways and can be connected on all sides to one another and to other components.
  • a further step in this direction means if the flanges on the web are arranged in the manner of a U-profile and their free ends facing away from the web are angled once or twice at right angles in such a way that a distance remains between them into which a second, similar profile bar fits with little play on the flange side.
  • a design of the new profile bar enables its simple and inexpensive manufacture. You can also insert a wall between his angled legs in this way and, thanks to the holes, fix it securely, as well as pipes or cables, so that this continues to benefit the versatility of the applications.
  • the first of these measures is that the holes are arranged in longitudinal rows, the distance from the center of the hole to the center of the hole being selected in such a way that the height of the profile in the web direction is an integral multiple thereof, and that the holes are adjacent Rows are at least offset in the longitudinal direction in the web. You can e.g. be offset by half a hole pitch so that the holes in every other row are at the same height. It is even advantageous if the profile height in the web direction is an even multiple of the distance from the center of the hole to the center of the hole, because then, especially with regard to the following measure, the dislocations in two profile bars that lie in any mutual position are in the same direction.
  • the second of these measures is that, at least in the web, the distances between adjacent rows of holes are selected so that they are the same or twice as large or partly the same, partly twice as large as the distance from hole center to hole center along a row of holes. It can easily be seen that this is particularly important for the connectivity of two intersecting profile bars. A distance from row of holes to row of holes that is twice the distance from the center of the hole to the center of the hole in a row is particularly worth considering where otherwise a row of holes would be in alignment with a leg portion of the profile that was angled twice and that would allow the screws to pass through Ways would be; the row of holes is expediently omitted there.
  • the third of these measures consists in that, at least in the web, the two outer rows of holes are at a distance from the adjacent profile edge which is equal to the distance between adjacent rows of holes.
  • the fourth of these measures consists in that round holes and elongated holes alternate within each row, with an elongated hole covering and replacing at least two round holes in a row consisting only of round holes. It is advisable to make the width of the elongated holes equal to the diameter of the round holes, at most except the elongated holes of a row in each of the flanges of the profile, where a larger elongated hole width can be provided for particularly thick tie rods, then expediently in the row adjacent to the web .
  • the arrangement of the holes in adjacent rows at least offset in the web then means that there is a round hole in the adjacent row next to an elongated hole in one row (and vice versa).
  • round holes and elongated holes are arranged in this way ensures that when two such profile bars intersect at any angle, round holes and elongated holes of a suitable position that are suitable for connection with screws are always sufficiently available, without one too small holes for screws that would only be able to withstand low loads and too small hole spacings, which would result in a substantial reduction in the section modulus's resistance torque.
  • the holes for the screws have nail holes of a correspondingly smaller diameter.
  • the known nail holes there are only the usual conditions, they are also suitable for wood screws of moderate diameter, their number can be significantly smaller than that of the holes for the load-bearing connecting screws, and wherever there is space for this, there is the given location for the nail holes.
  • the new profile bar can be manufactured by first cutting a sheet metal strip of the required width and length and punching the holes, and then cold-rolling it into the intended profile shape.
  • This method has the advantage that all holes of a section can be punched together in a still flat workpiece, which can then be transported a section length to the next punching operation.
  • structural steel is considered as the material for the new profile bar.
  • the profile rod e.g. galvanize, spray with aluminum or apply an anti-rust coating.
  • the more expensive manufacture of stainless steel saves post-treatment for manufacturing and possibly repairing the rust protection, greasing before use or before storage, etc., which at least partially compensates for the increase in price depending on the use, and that any remaining price increases are divided into many applications because the new profile bar can be used again and again.
  • the means of manufacturing the new profile bar would have been available many decades ago, and there can be no doubt about the need, as the new profile bar can be used for any, including high, requirements
  • Manufacture loaded load-bearing and support structures in a simple manner, e.g. lifting cranes, pallets, overpasses, halls, houses, half-timbered buildings, grandstands, storage racks, containers, etc., and a particular advantage lies in the simple and rapid creation of provisional structures such as scaffolding, supports for bridge construction and makeshift bridges including those for military purposes.
  • An embodiment of the new profile bar is on the attached drawing sheet in Fig. 1 in view of the web side, in Fig. 2 in section along the line AA, in Fig. 3 in view from below and in Fig. 4 in section along the line BB shown, while Fig. 5 and 6 show application examples for combination and connection of profile bars of the new type.
  • the profile bar shown in Fig. 1 - 4 consists of a web 1, there two flanges 2 and a first leg 3 and a second leg 4, which are angled from the flange 2 by 90 °.
  • Only in the flanges 2 are particularly wide elongated holes 7 in one row of holes, so that the new profile rod can also be used in special applications in which tie rods are to be passed through, which usually have a considerable diameter. Holes 5 - 7.
  • the height a in the web direction is twice as large as the flange width b, and the dimension c over each of the first two legs 3 is a track smaller than a / 4, so that a second, same profile bar can insert on the flange side between the legs with little play (as Fig. 5c, d, f, and g it shows).
  • the length d of the second leg 4 can be approximately equal to the dimension c mentioned.
  • the same dimension a returns in Fig.
  • the elongated holes 6 would have the same width; however, just like the sheet thickness e, this depends on the overall dimensions of the profile and, together with these, on the required section modulus of the profile bar.
  • FIG. 5 shows schematically in section and on a smaller scale than FIG. 2 some examples of the numerous possibilities for attaching and inserting profile bars of the new type; the screws serving to connect them are not shown.
  • the examples a) - e) in Fig. 5 provide information on how such profile bars can be joined together in order to obtain a greater section modulus with the combination; the moments of resistance of the individual profile bars add up if they are only connected to each other at the ends of a beam combined in this way, while the resulting section modulus, except for example b), is considerably greater if the profile bars are spaced apart over their entire length connects. In this way you can handle modest as well as heavy loads with the same profile bars, which considerably simplifies storage.
  • a simple branch is indicated, in example g) a reinforced crossing of two profile bars.
  • Fig. 6 shows schematically in perspective two examples of the numerous ways in which branches and crossings of profile bars of the new type can be designed. Again, the holes and the screws are not drawn, with which you can connect the profile bars in any case stable.
