Definitions

  • the invention relates to a tubular mast made of stacked tubular bodies, the diameter of which decreases towards the mast tip and which have a support for the tubular body to be attached in the region of their upper ends.
  • a tubular mast of this type DE-OS 1 434 785
  • the tubular bodies plugged onto one another to form a tubular mast are provided at their upper ends with firmly molded or loosely inserted flanges as supports for connecting the tubular bodies arranged one above the other, the connection itself using rod-shaped or rod-shaped clamping elements,. which are passed through the tubular body and pull them together in the longitudinal direction of the tubular mast.
  • the object of the invention is therefore to design the tubular mast of the type mentioned in such a way that the individual tubular bodies do not have to be clamped to one another or welded and still masts of any length can be produced without the risk that the individual stacked tube Detach body from each other or the strength of the mast, in particular its bending strength, is exceeded under the forces acting on it during and after the mast installation, as a result of which the mast breaks or kinks.
  • the tubular body is steel pipe sections, each having a retracted section that forms a circumferential shoulder against which the attached pipe section is directed and whose depth A measured in the direction of the longitudinal axis of the weft is greater than the wall thickness B of the pipe section attached , wherein the retracted section has a cylindrical or conical, tubular continuation adjoining the circumferential shoulder, via which the friction and clamping forces required to hold the pipe sections together can be transmitted by means of a conical, bush-like clamping device to the inside of the wall of the pipe section attached.
  • tubular masts according to the invention enable a considerable reduction in transport and storage costs, since the masts in lengths of more than 4 m required special transport vehicles. Now all usual means of transport can be used, since the mast sections do not exceed a maximum length of 4 m and are only put together at the installation site of the tubular mast.
  • the socket-like clamping device in the case of a cylindrical continuation, consists of a first cylindrical socket with an external cross-section which enlarges conically towards the circumferential shoulder and a second cylindrical socket which is inserted over the first socket and conically enlarges towards the circumferential shoulder Internal cross section formed.
  • the first bushing can have at its upper end an annular flange which is directed inwards to the longitudinal axis of the weft and which sits on the end face of the cylindrical extension.
  • the second bushing it has proven to be particularly advantageous for the second bushing to provide it at its lower end with an outwardly directed ring flange which sits on the lower end face of the plug-in pipe section which contains the second bushing.
  • This ring flange is designed in the manner of a sealing ring seated on the circumferential shoulder, as a result of which a special seal can be omitted.
  • the bush-like clamping device can consist of a single cylindrical bush with an inner diameter that increases continuously towards the circumferential shoulder. On this saves one of the two bushings without losing the advantageous properties of the construction according to the invention.
  • the circumferential shoulder can lie at the end of the conically drawn-in section and form the transition to the cylindrical section onto which the cylindrical section of the following pipe section can be plugged.
  • the surfaces of these pipe sections merge flush in the area of the circumferential shoulder, i.e. without forming a shoulder or a step.
  • the clamping bush is on its lower, the peripheral shoulder of the lower pipe section facing end with an annular flange which has an upward shoulder with which it sits on the end face of the attached pipe section and has a small distance from the circumferential shoulder of the lower pipe section.
  • the ring flange can form a downward-facing bearing shoulder, which rests on the circumferential shoulder of the lower pipe section, wherein, according to a further advantageous embodiment, the circumferential shoulder forms a conical pipe section, the inclination angle a. to the pipe longitudinal axis is greater than the angle of inclination ⁇ of the conically drawn-in section of the lower pipe section adjoining the circumferential shoulder.
  • the clamping bush can also be provided with only a single axial slot which can be compressed when it is pushed into the upper pipe section and thereby clamps the inserted clamping bush in the pipe section.
  • FIG. 1 shows two stacked steel pipe sections 2, 3, of which the lower pipe section 3 has a conically retracted section 17 which begins at a lower cylindrical mast section 22 shown in FIG. 3 and tapers to the circumferential shoulder 4, which forms the transition to the cylindrical section 19 onto which the cylindrical section 21 of the following upper steel tube section 2 is attached.
  • the circumferential shoulder forms an almost horizontal support on which there is a spacer or sealing ring 6 which is flush with the outer edge of the circumferential shoulder.
  • the depth A of the circumferential shoulder 4 measured in the direction of the longitudinal axis 18 of the weft is greater than the wall thickness B of the pipe weft 2 attached.
  • a conical, bush-like clamping device which, in the embodiment shown in FIG. 1, consists of a first cylindrical bushing 7 with a cross-section which widens conically in the direction of the circumferential shoulder 4 or a continuously increasing outside diameter and from one of the above first socket 7 is inserted socket 8 with reverse taper, ie with the inner cross-section or inner diameter increasing continuously in the direction of the circumferential shoulder 4.
  • the socket 7 has at its upper end an inwardly directed to the longitudinal axis 18 of the ring flange 9, with which it rests on the end face of the cylindrical extension 19.
  • the second bushing 8 has at its lower end an outwardly directed annular flange 5, which sits on the lower end face of the attached upper pipe section 2 and, in the installed state shown in FIG. 1, rests as a spacer or sealing ring 6.
  • the two bushings 7 and 8 are thus wedged to one another and to the pipe sections delimiting them in the installed state of two stacked pipe sections, thus transmitting the friction and clamping forces required to hold the two pipe sections 2, 3 together.
  • this cohesion is not so strong that the pipe sections cannot be separated from one another with a suitable lever tool if the pipe mast height is to be changed by using longer or shorter sections. The latter would be the case, for example, if the tubular mast is set up as a light mast and the light point height changes due to a change in the type of luminaire or the fitting with other mirror optics.
  • the two wedges 7, 8 which are seated one on top of the other are each provided with a slot 15, 23 which extends in the direction of their longitudinal axis, as can be seen from FIG. 2.
  • These slots allow the cylindrical bushes with conically tapering cross-sectional dimensions to be stretched or pressed together to adapt to manufacturing tolerances when the two tubular mast sections 2, 3 are plugged onto one another.
  • This assembly takes place in such a way that the first bushing 7 is first plugged onto the cylindrical extension 19 of the lower pipe section 3, until it stops Ring flange 9. Then the upper pipe section 2, into which the second cylindrical bushing 8 has already been inserted up to the stop of its ring flange 5, is pushed onto the bushing 7 until the ring flange 9 meets the spacer or sealing ring 6.
  • the length of the overlap area of the two pipe sections 2, 3 connected to one another, along which the inside of the upper, placed pipe section with the inserted second bushing 8 rests on the outside of the first bushing 7 plugged onto the lower pipe section, is greater than the average pipe section diameter in the overlap area of the two shots.
  • a single bushing 10 is used, which has an internal cross section which increases conically in the direction of the shoulder 13 and which extends upwards from the shoulder 13 conical tapered continuation 20 is attached.
  • the bushing 10 has a lower ring flange which replaces a spacer or sealing ring.
  • the upper pipe section which is shown in broken lines in FIG. 3, is pushed over the bushing 10.
  • FIG. 4 shows two stacked steel pipe sections 30, 31, of which the lower pipe section 30 has a conically drawn-in section 32, the angle of inclination p of which to the pipe longitudinal axis 34 is smaller than the conical pipe section adjoining this section, which forms a circumferential shoulder 29 and whose angle of inclination to the tube longitudinal axis 34 is designated by ⁇ .
  • this tube mast also consists of several stacked tube sections 30, 31, the diameter of which decrease towards the mast tip and each have a retracted section which forms a circumferential shoulder of the type designated 29 against the the respectively attached pipe section is directed and the depth A measured in the direction of the pipe section longitudinal axis 34, as can be seen in FIG. 1, is greater than the wall thickness B of the attached pipe section.
  • the drawn-in, conical section of the lower pipe section 30 has a conical, tubular extension 35 beyond the adjoining circumferential shoulder 39, the diameter of which continuously tapers towards the upper end of the lower pipe section 30.
  • the clamping bush 28 is also conical, with an internal cross-section which increases continuously in the direction of the circumferential shoulder 29.
  • annular flange 24 has an upwardly directed shoulder 25 with which it can be attached on the front side of the Pipe section 31 sits.
  • the ring flange 24 forms a downward-facing bearing shoulder 26, which is at a small distance from the peripheral shoulder 29 of the lower pipe section 30, which is approximately up to 3 mm, but in extreme cases also rests on the peripheral shoulder. This distance serves the purpose of slipping the conical clamping bush to allow with the pipe section 31 sitting on it when setting up the pipe mast until the clamping bush clamps on the surface of the tubular extension 35.
  • the angle of inclination x of the circumferential shoulder 29 is 30 °, while the angle of inclination p of the conical, drawn-in section adjoining the shoulder in the direction of the lower end of the lower pipe section 30 is 15 °.
  • the angle of inclination of the tubular extension 35 of the lower pipe section to be tapered upwards is 1 ° and the outer diameter at the upper end of this continuation is 74 mm, while the outer diameter of the attached upper pipe section 31 is 76 mm. It is understood that these dimensions are only to be understood as examples, which are not intended to be limiting in any way.
  • the angle of inclination ⁇ , the circumferential shoulder 29 corresponds to the angle of inclination of the downwardly directed bearing shoulder 26 of the ring flange 24.
  • the clamping bush 28 is divided into two by two axially extending slots 36a and 36b, and the two clamping bush parts are pressed against the inner wall of the upper pipe socket 31 to be attached by a spring 27 which is located in an annular groove 33 of these two 5, this construction makes assembly considerably easier if the two pipe sections are to be plugged onto one another, since the spring 27 prevents the clamping bush 28 inserted into the upper pipe section 31 when the pipe is put on shot slides down. As can be seen, the spring 27 extends as an almost closed ring around the inner circumference of the two successive parts of the clamping bush 28 within the ring groove 33.
  • the ring flange 24 delimiting the lower end of the clamping bush 28 makes a separate sealing or spacer ring unnecessary and thereby simplifies the manufacture and assembly of the tubular mast. In addition, this construction ensures that the pipe sections 30 and 31 plugged onto one another remain firmly connected to one another.
