STEIGSPROSSE

RK 396,961 B the Erfindang concerns a Steigsprosse fur poles more ocler such, with a stangenf6rmigen footstep-hurries, at whose elnem end for attachment at the mast or such a thing, intended mounting element and at its other end a Trittbegrenzangsnnd Abrutschsichemngsteil anschlieBt. Derartlge Steigsprossen are used insbesondtre with powerline masts to make possible to mounting these Leltungsmasten filr Installationsoder repair work or such a thing. In detail attached thereby in iiblicher way at a Eckstiel of such a mast Steigsprossen alternating around 90° to each other shifts more iibereinander for instance in Abstiinden of 40 cm. The well-known Steigsprossen consist thereby of bars whereby to a rod end is intended tin a thread section as Befestigungstell for the attachment of the Steigsprosse at the mast Eekstiel, and whereby at the other rod end likewise a Gewindeabsehnitt is intended, on which as Trittbegrenzungsund slipping they ago part a mother is aufgeschranbt. These well-known Steigsprossen are particularly when Niisse and freezing up relatively more ansieher, like that dab the danger of slipping are given. Now already upper putting wnrden employed to plan fiir the persons ascending on the mast a cable safety device in the kind as with the Klettem whereby a proposal went by attach at the Eckstiel of the mast within the range of the Steigsprossen zus tzlich rope loops at which a climbing rope with the help of yon Karabinem concern be gt can. This Sieherungsteehnik is jedoeh open-itself-twists complex, particularly because of zus the tzlichen Anbringang of the Seilsehlaufen and animal snap hook. Conceivably commodity also training of the Steigsprossen with rings at the freely auskragenden iiul] eren end, into which Kambiner be received are ngt, at which schliel lich the Sichemngsseil one fastens. Also hereby open-see-borrowed a relatively high expenditure write connected. Above all w/ire with these L6sung also the attachment of the footstep delimitation and of slipping safety device part problematic, which has the task, lateral slipping, in I.angsriehtung of the stangenf6rmigen Steigsprosse and/or more exactly said yon of them footstep-hurry, to that. The task zugmnde was appropriate for the invention to plan a Steigsprosse of the initially angefiihrten kind which with simple, inexpensive training a high MaB at Abrutsehsieherheit offers just like a simple possibility animal protection with a rope. I-Iierzu is gekennzeiehnet eff'mdungsgem fuel element the Steigsprosse of the initially indicated kind thereby, daB Trittbegrenzungsund slipping safety device part by of footstep-hurries and bent to a Einhting6se with a lateral Einh ngzugang for a safety device rope formed Stangenabschnitt is formed. With a such Ansbildnng in favourable Wise one corresponds to the managing objective. Yon footstep-hurry bent, the EinhangSst bildendt Stangenabschnitt erfiillt thereby two Fnnktionen, namlich on the one hand those Trittbegrenzungsund of slipping safety device part, by it of footstep-hurry accordingly weir is bent and hochbzw. is away, as well as on the other hand those the admission of the safety device rope, niimlich in tlinh the giise, which often laterally are, in order the safety device rope used with the Hoehsteigtn simply einhangen to kSnnen. erfindungsgemaB the trained Steigsprosse offers thus a high MaB at security, protecting it doeh anclererseits a einfaehe animal position ermtiglicht to and to be so inexpensive manufactured can. In the interest of one benders einfaehen ii-production is here favourable it, if the Stangenabschnitt is curved to the Bildang of the Einhiing6se wendelf6rmig. Einfaeh, dab that can be preferably planned the Einh g6se screen end Stangenabschnitt more gegeniiber footstep-hurries Nm ungef'; thr 1 1/4 turns wendelf6rmig gebogtn is insgemmt. The EinlngOse will here thus be addressed by a turn of the Stangenal of cut (according to 360°) in an educated manner, whereby the end of the Stangenabschnittes is bent around further 90° zusiitzlich, wodureh the advantage erreieht, dab this rod end in a direction away yon that side of the Steigsprossen can, on the respective person to the Steigsprossen is high-climbed. It can be zweckm industrial union, a ausgeprfigtes, to plan relatively long rod end over clas Einf ideln and/or Einhfingen of the Sichemngsseils under Ftihrung along Diesel rod end to edeiehtem, and in this case it is gtinstig welters, if to the helical EinhfingOse anschliegendes a iuBeres, straight-line rod end of footstep-hurry rectangular, in plan view seen, is away. Furthermore it is beer, in order to arrange the Einhtingen of the safety device rope particularly easily, anch yon advantage, if the straight-line iai] ere rod end schrfig to a Normalebtne on the Aehse of the wendelf6rmigen EinhfingOse verl iuft. Actually the Einhang0se, which will receive by wendelf0rmiges a bending of the Stangenabschnittes, in Draufsieht can have for example a liingliche, oval form. In the interest of particularly simple production it is however gfinsfig, if the wendelf6rmige is circular a slope eye in Dmufsicht. The Stangenabschnitt can with the production simply around a cathedral-like, preformed tool restrains to be bent. Versuehe with the Steigsprosse trained invention in accordance with industrial union showed, dal] in case of tints Absturzts of a gesieherten person (Versuehe were durehgeftihrt with appropriate load masses, which were fastened to the safety device rope and to high ones of 1,60 an m above one invention in accordance with IL] EN safety climbing rung fall were left), thus with the “in-that-Seilfallen”, dureh that relafiv are enough for load lever, which the rungs with their footstep-hurry form, one verh iltnismlil3ig grol3e notch effect within the range of the internal end of the Tfitteiles, where the tiblicherweise threaded attachment section arises anschliel to t. Around this notch effect world as possible to rear-continue in such a way and o a further ErhShung of the they agoness to RK 396,961 B, is of advantage it erreiehen aucla, if during planning a mounting thread at the mounting element this thread to footstep-hurry lain is running out cut. Reduced by a such .auslaufend gesehnittenes mounting thread the unerwiinschte notch effect within the range of the Uber.gangs to footstep-hurry to practically zero, so dab breaking or a Abreil? , EN of the Steigsprosse in this Ubergangsbereieh during the high load arising with a crash of a person (kN to lie can do in the Bereieh yon the 20 to 25) to be prevented can. There invention in accordance with ll? , e Steigsprosse in the indicated accident situation, if a person stiirzt into the they ago rope, a bend to be subject may, jedocla break may not, should it of a material with a sufficient firmness and/or Z be igkeit made, and in this connection has see proven as particularly favourable, if the Steigsprosse of a warm-deformed and wiirrnebehandelten round steel bar consists. For example a round steel bar with 20 mm of Durehmesser of the Giite St42 can be used, which is erwiirrnt before bending, and animal after the Biegeverformung is without tension gegltiht. Then the Steigsprosse in on can sees to iiblicher way for Korrosionssehutz being hot-dip galvanized and/or with a painting of corrosion be provided. The invention below tutert on the basis one in the design illustrated preferential Ausfiihrungsbeispieles noeh more welter erl. In detail show thereby in the design: Fig. I a aussehnittsweise regards a powerline mast within the range of a Eckstiels, at which Steigsprossen are angebraeht; Fig. 2 and 3 cuts gemiiB the lines (II-II) and/or (lII llI) in Fig. 1; Fig. 4 a plan view on a erfindungsgemiiBe Steigsprosse, Fig. 5 a longing CCIT representation of this Steigsprosse, gemal3 of the line (V-V) in Fig. 4; and Fig. 6 a side view of the Steigsprosse in accordance with 13 Fig. 4. In Fig. 1 is to-strike-borrowed to herkiSmmlicher design a Aussehnitt of a powerline mast yon, with the four Eekstiele, of those one in Fig. 1, with (1), are vemnschaulieht, by schriige reinforcement props (2) are framework-like connected. The Eekstiel (1) consists, like in particular of Fig. 2 and 3 is ersichflich, from a bracket section, and in entspreehender way k6nnen aueh the props consist (2) of bracket sections, as this see on to herk6mmlieh is. At the Eckstiel (1) are, as from Fig. 1 to 3 ersichtlieh is, in on sees likewise herk6mmlieher way Steigsprossen fastened, which are against each other transferred alternating by 90°, i.e. alternating to and/or other Sehenkel (3) and/or (4) the Eeksfiel (1) of forming bracket section are fastened. In detail thereby for example herk6mmliehe Steigsprossen (5) and/or (5 ') can on the one hand as well as - for example as each fourth Steigsprosse - invention in accordance with trained Steigsprossen (6) to be intended. With this configuration and with an actually iiblichen distance two Steigsprossen shifted by 90° (5), (6) and/or (5), (5 ') zwisehen against each other from 40 em results thus a distance erfindungsgemitB of the trained safety climbing rungs (6) yon 160 cm. This distance yon 1.60 m has itself as giinstig and sufficiently in connection with the Einh ngen one yon high-climbing persons of used safety device rope proven. From Fig. 1 and Fig. 3 is ersichtlieh, dab the conventional Steigsprosse (5) and/or (5 ') with a mounting element (7) at the respective Sehenkel (3) (and/or (4) in the case de, Steigsprosse (5 ')) , whereby the attachment herk of of the mmlichen, stangenftirmigen Steigsprosse (5) and/or (5 ') taken place via it, dab the mounting element (7) in form of a thread section is fastened dnrch a hole in the bracket section Sehenkel (3) and/or (4) gesteekt and with the help of yon nuts (8) and/or (9) at this thigh (3) and/or (4) are tightened. The well-known Steigsprosse (5) and/or (5 ') possesses then a stangenf0rmigen footstep-hurry (10) as well as at the freely auskragenden ul3eren end Trittbegrenzungsund Abrutsehsieherungsteil (11), which is formed by one on a thread section aufgeselaraubte mother. In appropriate way aueh invention in accordance with trained safety climbing rung (6) from a bar to be formed, whereby at an end a thread Befestigungsabsehnitt (12) can - anlieh the attachment section (7) with the herk0mmlichen Steigsprossen (5) and/or (5 ') - is intended is gesteekt, animal by a Bob_rung or Offnung in the appropriate Sehenkel (4) of the hitting a corner handle bracket section (1) and tightened with the help of yon Muttem (13), (14). At this Befestigungstell (1: 2) schlieflt again eln stangenf6rmlger footstep-hurry (15) on, below in its iiul3erem end Trittbegrenzungsund Abrutsehsicherungsteil (16) anschliel3t, dessert training on the basis the Fig. 4 big 6 no more in the detail erl to be iutert soil. From Fig. 3 is further see-borrowed, dab the safety climbing rung (6) regarding the dynamic loads from one, unequally arising with a crash, hiSheren in the Vergleieh to a blol3en rising a person, substantially st rkeren bar in the comparison to the herkiSmmliehen Steigsprosse (5) (and/or (5 ')), which has to take up nnr a static load, is manufactured. Further is in Fig. 2 the Vollst ndigkeit half illustrated, like the respective reinforcement props (2) with the help of yon bolts and mother at the flanges and/or thighs, e.g. (3), the Eckstiel (1) of forming bracket section are attached. Trittbegrenzungsund slipping safety device part (16) of the safety climbing rung (6) consists, like outer r of the Fig. 1 big 3 in particular from the Fig. 4 to 6 follows, from one of footstep-hurry (15) high-curved Stmagenabschnitt (17), which thereby to a Einh ng6se (18) is curved wendelf6rmig, and whose free, uBeres, straight-line rod end (19) in plan view (S. Fig. 2, 3 and 4) right-angled to stangenf the Srmigen footstep-hurry (15) sew in the back, seen yon on the Steigsprossen (5), (5 ') and (6) ascending person seen, is away. RK 396,961 B thereby start this free rod end (19) with the Hochklettem, and it is not minimized also with a any Abstum the Gef'ahrdung of the stiiizenden person by this free rod end (19). Dutch the helically bent Stangenabschnitt (17) Einh gOse (18) gebildetet is yon the side ftir a Einhiingen $icherungsseiles course resembled ago, whereby free rod end (19) the Einf ideln or Einhangen of the $icherungsseiles into the EinhiingOse (18) erleichteL before the configuration of the Einhang0se (18) now in the detail on the basis the Fig. 4 to 6 one tutert erl, is still referred to it, dab in the Fig. tbis 3 sehematisch with (20) a safety device rope illustrated is, which into the respective Einhiing6sen (18) the Sieherh, its Stoigsprossen (6) be received is tngt. From the Fig. 4 his 6 is interpret-borrowed recognizably, how to footstep-hurry (15) the safety climbing rung (6) I0 ansehliel? nda Stangenabsehnitt (17) wendelf6rmig or sehraubenlinienf&mig - with one $teigung yon beispielsweiga ungefmhr 45° - curved is, in order to form the EinhEng6se (18). This Einh g6se (18) is, as from Fig, 4 is recognizable, in Draufsieht kreisf6rmig, and free rod end (19) stands, gam this Draufsieht in Fig. 4, reehtwinkalig veto tangenfOrmigen footstep-hurry (15) off. Wia more famer from Fig. 5 see-flee is, verl uft aliases free uBere rod end (19) very g to the Aehse (21) animal Einh irtg6 e (18), i.e. under an angle of for example ungef its 15° to liner normal level on this Aehse (21). This normal level is in Fig. 5 suggested with (22) schematically. The free rod end (19) ftihn the they ago rope (20) (Fig. 1 big 3) with the Einh laterally open Einh ingen ingzugang (23) into a slope eye (18) to of them (Fig. 6), which will receive dutch the Wandolform or spiral form of the Stangenabschnitts (17). In a prototype the descriptive safety climbing rung (6) made of 20 a mm round steel bar, which was heated up before bending a warm treatment submitted and for bending animal Einh gOse (18) became; the Stangenabschnitt (17) was bent however an accordingly preformed tool by machine, with the help of yon roles. After dam bending procedure the Steigsprosse (6) without tension gegliiht, according to which a thread in the attachment section (12) became it eingeschnltten became. Diesel thread is thereby vomug points running out sum footstep-hurries (15) to schnelden, all the notch effect dutch the thread cuts at the Ubergang (24) between dam mounting element (12) and dam footstep-hurries (15) with the dynamic Belasmngen arising in crash situations to that. The ton exhaltene Steigsprosse (6) with a Priifmasse yon 80 kg was then tested, whereby the Staigsprosse (6) to a Steer comparably a mast hitting a corner handle was fastened, the Priifmasse at a “Sieherungs” - rope to the Einh ing6se (18) concern and from airier H6he of 1,60 m above the Einhiing6se (18) falling gel ASS became gt. , Differently as in practice, unged a mpftes steel cable than “Sieherungs” - rope were used, thus dab fttr this Priifung ungiinstigera conditions planned, when they arise act ehlieh in practice wttrden, incoming goods the laerk0mmlichen Siehemngssaile - became iiblieherweise Kemmantelseile - eina certain stretch to exhibit. In accordance with flat steel bar one became much abrupta dynamisehe load on the Steigsprosse with the durehgefiihrten Testa (6) herbeigeftihrt, airier Kraft yon ungef HR 20 to 25 kN entspmeh. , Dab itself the descriptive showed up Steigsprosse (6) within the range of the upper course (24) bent downward, not however fallow. In such a way tested Steigsprosse (6) thereby a Gesamd Inge had yon 270 RAM, animal mounting element (12) had a lung yon 60 mm, which Lense of footstep ILS (zwisehen dam upper course (24) and of the Einhang0se (18)) ungef r amounted to 130 RAM, and the Offnung (clearance) the Einhang6se (18) has a diameter yon 25 RAM. The I-I6he de wendelf6rmig curved Stangenabsehnitts (17) - that is the H6he, like it from Fig. 5 ersiehdieh actual 80 RAM amounted to, whereby the H6he of the actual Einhang6se (according to a 360° turn of the Stangenabsehnitm (17)) 65 mm, which meant, dab the distance between the two centers of the Kreigquergehnitta amounted to, as sia from Fig. 5 is, thus the GanghShe see-borrowed, to 45 mm amounted to (Irish Republican Army iii-view aaf the mm-Materialgt ke of the Rnndstahls). The Gesamtl nge of the free rod end (19) amounted to ungef HR 80 RAM. Alg material Ittr the Sieherheita Steiggprosse (6) a z it was used steel of the type St42. The bagehfiabene Steiggprosse (6) zweeks Korrosionssehutz of airier Feuorverzinkung can warden submitted, WAD of tiberdies can in the installed condition in the Bereieh of the Sehraubverbindung (at the Eckstiel (1)) a color coating angebraeht warden, which forms apart yon animal Korrosionssehutzwirkung in the Gawindebereieh aueh one zus tzliche protection against loosening the mother (13) nnd (14). Dariiber outside ermSglieht this color coating also an optical OlSerprtifung of the Befestigungsbereiehes in the I-Iinbliek on a Loekem the mother. Ftir this color coating konnen for example Mischpolymerigate with alkyd resins einge etzt warden. It is see-borrowed, dab the descriptive safety climbing rung (6) with to a slope eye (18) wendelf6rmig - around altogether 360° ÷ 90° = 450° - curved the Stangenabschnitt (17) not only verhalmism industrial union einfaeh and to be inexpensive manufactured can, but iiberdies zus itzlich for the function of a Abrutaehgieherung against seifliches slipping veto footstep-hurry (15) also the Sicherungsfunkfion itself-twist the Einh ingens a safety device rope (20) erfiillt. Daz free Smngenende (I9) is waiters, like in particular A, s Fig. arsiehtlieh, thus, dab it is bent 3 with a fall no Verletzungsrislko fiir the absttirzende, in the they ago rope (20) falling person forms, there this person in the wesenflichen in by the Steigsprossen (5) and (6) defined area (25) (Fig. 3) frilly. If the invention became to besehrieben managing on the basis einas particularly preferential Ausfiihrungsbeispiels, then are doeh Abwandlungan and Modifikafionen mSglieh, without vedassen the frameworks of the invention. RK 396,961 B like that is also conceivable it in particular to bend the Stangenabschnitt (17) not only in accordance with IL to a turn of a Winding (and/or 1 1/4 turns) wendelf6rmig sondem in for example two Schmubeng ingen, with a Gangh0he yon for example 45 mm, according to the distance animal of both centers of the circular cross-sections, like managing in connection with Fig. 5 one indicated. Also the free rod end (19) could be planned more kiirzer, and in particular in the case yon several turns fiir a slope eye (18) iiberhaupt to be omitted. A further Abwandlang bestfinde for example dafin, instead of one in Dranfsicht (Fig. 4) to bend kreisf0rmigen Einh ing6se (18) an oval or ann emd rectangular (with rounded off corners) Einhiing6se (18) from the Stangenabschnitt (17).
