Opfindelsen angår en forbindelsesjcobling for masteelemen£er, navnlig masteelementer til en tårnkranmast, hvilke elementer ved deres ender har lasker med komplementar form med en endeflade og et i afstand fra denne beliggende fremspringende brysti, og 5 som er således udformet, at endefladen på hver .af laskerne kan ligge tæt an mod brystet på en modsatrettet laske.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a connecting coupling for the mast members, in particular mast elements for a tower crane mast, which elements at their ends have complementary shaped cylinders having an end face and a projecting breast path spaced therefrom, and so formed that the end face of each. of the lasers may lie close to the chest of an opposite ligament.
Der kendes en forbindelseskobling af denne art fra bekrivel-sen til USA patent nr. 3250401. Ved denne kendte·kobling ligger laskerne direkte an mod hinanden,både for så vidt angår endefla-10 derne og de fremspringende bryster, og hvad angår en. imellem disse liggende,tværgående flade. I koblingens sammenkoblede stilling holdes laskerne i indgreb med hinanden ved hjælp af en bolt, som er ført igennem labber, som rager ud i sideretningen fra hver laske. For at opnå en slørfri kobling af denne art er det nødven-15 digt,at laskerne bearbejdes meget nøjagtigt. , »A connection coupling of this kind is known from the specification of United States Patent No. 3250401. In this known coupling, the lasers are directly facing each other, both in respect of the end surfaces and the protruding breasts, and in respect of one. between these horizontal transverse surfaces. In the coupled position of the coupler, the lugs are held in engagement with each other by means of a bolt, which is passed through lobes which project in the lateral direction from each lug. In order to achieve a blur-free coupling of this kind, it is necessary that the lasers be machined very accurately. , »
Forbindelseskoblingen ifølge den foreliggende opfindelse er ejendommelig ved, at laskerne er udformet på en sådan (méde, at de mellem sig i deres i hinanden indgribende stilling danner ' en tværs gennem de i hinanden indgribende lasker førende åbning, 20 hvilken åbning har mindst én skråflade, og; hvori der er anbragt en låse- og forspændingskile, ved hjælp af hvilken de to flasker er spændt mod hinanden, samt ved at der findes centreringsorganer, der bæres af laskerne til sikring af disses indbyrdes styring og anbringelse. Herved opnås det, at den pågældende kobling 25 kan sættes under forspænding, idet endefladerne og brysterne ved kilens inddrivning drives mod hinanden, således at der mellem de mod hinanden anliggende endeflader og bryster kan tilvejebringes et anlægstryk, hvorved slør udelukkes, og der opnås en meget stabil kobling.The connection coupling according to the present invention is characterized in that the lasers are designed in such a way that they form a transverse opening through the interlocking lasers, which have at least one inclined surface between them. and wherein a locking and biasing wedge is provided, by means of which the two bottles are clamped against each other, and that there are centering means carried by the cylinders to ensure their mutual control and placement. the respective coupling 25 can be pre-stressed, the end faces and breasts being driven towards each other by the drive of the wedge, so that between the end faces and breasts adjacent to each other a contact pressure can be provided, whereby the veil is excluded and a very stable coupling is obtained.
30 En udførelsesform for koblingen ifølge opfindelsen er ejea- u dommelig ved, at de to forbindelseslasker i sammensat stilling afgrænser et volumen med firkantet eller rektangulært tværsnit, i forhold til hvilket tværsnit låsekilen er anbragt diagonalt.An embodiment of the coupling according to the invention is also judicious in that the two connecting lugs in a compound position define a volume of square or rectangular cross-section, relative to which cross-section the wedge wedge is arranged diagonally.
Herved opnås der maksimale anlægsflader for låsekilen, og derved 35 øges koblingens pålidelighed yderligere.This provides maximum abutment surfaces for the lock wedge, further increasing the reliability of the coupling.
En yderligere udførelsesform for koblingen er ifølge opfindelsen ejendommelig ved, at de to forbindelseslasker i sammensat stilling afgrænser et volumen med i hovedsagen cylindrisk form^i 145490 2 forhold til hvilket låsekilen er anbragt praktisk taget i et plan gennem det cylindriske volumens akse. Denne udførelsesform for koblingen er fordelagtig, idet der i stedse stigende grad anvendes cylindriske elementer til masteelementer,og en cylindrisk form 5 som angivet egner sig godt til anvendelse i forbindelse med sådanne elementer.A further embodiment of the coupling according to the invention is characterized in that the two connecting lugs in a compound position define a volume of generally cylindrical shape relative to which the lock wedge is arranged practically in a plane through the axis of the cylindrical volume. This embodiment of the coupling is advantageous in that cylindrical elements are increasingly used for mast elements, and a cylindrical shape 5 as indicated is well suited for use in connection with such elements.
En yderligere udførelsesform for koblingen ifølge opfindelsen er ejendommelig ved, at både låsekilen og åbningen, hvori den er indsat, har to skråflader, der er skråtstillet på symme-10 trisk måde. Herved opnås der en ensartet påvirkning af de to lasker under inddrivningen af kilen og derved også ensartede anlægstryk imellem endefladerne og brysterne.A further embodiment of the coupling according to the invention is characterized in that both the locking wedge and the opening in which it is inserted have two inclined surfaces which are inclined in a symmetrical manner. This results in a uniform influence of the two loops during the driving of the wedge and thereby also uniform abutment pressure between the end faces and the breasts.
En yderligere udførelsesform for koblingen ifølge opfindelsen er ejendommelig ved, at hver laske har en del med trekantet 15 tværsnit, der har en skråflade, som i to laskers sammenstillede stilling befinder sig vendende mod en lignende skråflade på den anden laske, samt at kilen har skråflader med tilsvarende form. Denne udførelsesform er fordelagtig i de tilfælde, hvor de elementer, der skal sammenkobles, har firkantet tværsnit, idet 20 sådanne elementer kan forbindes med lasker som angivet på flugtende måde.A further embodiment of the coupling according to the invention is characterized in that each groove has a section of triangular cross-section which has an inclined surface, which in two assembled positions is facing a similar inclined surface on the other latter, and that the wedge has inclined surfaces. with similar shape. This embodiment is advantageous in cases where the elements to be interconnected have a square cross-section, since such elements can be connected to lasers as indicated in a cursory manner.
En yderligere udførelsesform for koblingen ifølge opfindelsen er ejendommelig ved, at laskerne har indbyrdes ens form og dimensioner, samt at de to skråflader på deres dele med trekan-25 tet tværsnit og de to skråflader på kilen alle har samme hældning. Denne udførelsesform er fordelagtig ved, at fremstillingen af laskerne lettes, idet der kun kræves ens udformede lasker.A further embodiment of the coupling according to the invention is characterized in that the lugs have mutually similar shapes and dimensions, and that the two inclined surfaces of their parts with triangular cross-section and the two inclined surfaces of the wedge all have the same inclination. This embodiment is advantageous in that the manufacture of the lasers is facilitated by requiring only uniformly designed lasers.
En yderligere udførelsesform for koblingen er ifølge opfindelsen ejendommelig ved, at låsekilen og åbningen, hvori den 30 er indsat, har et parallelogramformet tværsnit, og at de to konvergerende flader har en hældning både i længde- og tværretningen. Denne udførelsesform er fordelagtig ved, at den nævnte dobbelte hældning af de to konvergerende flader samtidig bidrager til, at laskerne spændes sammen mod hinanden i tværretningen ved kilens 3 5 inddrivning.A further embodiment of the coupling according to the invention is characterized in that the locking wedge and the opening in which it is inserted have a parallelogram-shaped cross-section and that the two converging faces have a longitudinal and transverse inclination. This embodiment is advantageous in that said double slope of the two converging surfaces simultaneously contributes to the lasers being clamped together in the transverse direction by the drive of the wedge.
En yderligere udførelsesform for koblingen ifølge opfindelsen er ejendommelig ved, at låsekilen og åbningen, hvori den er indsat, har et cirkulært tværsnit, og at disse to dele har til hin- 145490 3 anden svarende konisk form. Denne udførelsesform er fordelagtig ved, at den er let at fremstille i kraft afat både åbningen og kilen kan fremstilles maskinelt på meget simpel måde.A further embodiment of the coupling according to the invention is characterized in that the locking wedge and the opening in which it is inserted have a circular cross-section and that these two parts have a second conical shape corresponding to each other. This embodiment is advantageous in that it is easy to manufacture by virtue of both the opening and the wedge being machined in a very simple manner.
Til låsning af kilen og til opretholdelse af koblingens for-5 spænding kan låsekilen ifølge en yderligere udførelsesform for opfindelsen være forlænget ved sin ende med mindst tværsnit med en gevindforsynet stang, hvorpå der er #kruet en spænd-,og låsemøtrik til afgivelse af en kraft til l&sekilen og ved reaktion til de to forbindelseslasker.For locking the wedge and maintaining the tension of the clutch, the locking wedge according to a further embodiment of the invention may be extended at its end with at least a cross-section with a threaded rod, on which a tightening and locking nut is provided for releasing a force. to the l & secil and by reaction to the two junctions.
10 En sikker styring og anbringelse af laskerne indbyrdes opnås, såfremt centreringsorganerne ifølge en yderligere udførelsesform for opfindelsen udgøres af en tap med i hovedsagen cylindrisk eller konisk form på hver forbindelseslaske og af et dertil komplementært taphul i den anden laske.A safe control and placement of the lasers among themselves is achieved if the centering means according to a further embodiment of the invention is constituted by a pin having a generally cylindrical or conical shape on each connecting pin and a complementary pin hole in the second pin.
15 Herunder kan centrerings tappene ifølge en yderligere udførel- 'f sesform for opfindelsen rage ud fra det'fremspringende bryst eller endefladen på hver laske, medens de komplementære taphuller er udformet i endefladen eller i brystet på hver laske. Herved opnås det, at centreringstappene og de dermed komplementære 20 taphuller kommer til at forløbe stort set aksialt i forhold til de elementer, hvortil laskerne er fastgjort, og dette letter sammenstillingen af laskerne, idet tappene kan indføres i taphullerne ved en aksial forskydning af laskerne.Below, the centering pins according to a further embodiment of the invention may protrude from the protruding chest or end surface of each groove, while the complementary pin holes are formed in the end surface or chest of each groove. Hereby, it is achieved that the centering pins and the complementary pinholes therefor will proceed largely axially with respect to the elements to which the lasers are attached, and this facilitates the assembly of the lasers, since the pins can be inserted into the pinholes by an axial displacement of the lasers.
Endnu en udførelsesform for koblingen'· er ifølge opfindelsen 25 ejendommelig ved, at centreringsorganerne på hver laske består af et fremspring og et dermed komplementært spor, og at et af disse befinder sig på laskens endeflade og det andet på laskens bryst. Sådanne centreringsorganer er fordelagtige ved, at de bidrager til at modvirke en drejning af laskerne i forhold til hin-30 anden.Yet another embodiment of the coupling according to the invention is characterized in that the centering means of each groove consists of a projection and a consequent complementary groove, one of which is on the end surface of the groove and the other on the breast of the groove. Such centering means are advantageous in that they assist in counteracting the rotation of the lasers relative to each other.
Centreringsorganerne kan også ifølge en yderligere udførelses-form for opfindelsen være tilvejebragt ved, at hver laske har en hældende endeflade, og at der på laskens bryst findes en flade med tilsvarende hældning. Herved opnås det, at endefladen 35 og brystet foruden at tjene som anlægsflader også kommer; til < at tjene som centreringsorganeri hvorved udformningen af koblingen simplificeres.The centering means may also according to a further embodiment of the invention be provided in that each lacquer has an inclined end surface and that on the breast of the lacquer there is a surface of corresponding inclination. Hereby it is obtained that the end surface 35 and the breast, in addition to serving as abutment surfaces, also come; to serve as a centering means, thereby simplifying the design of the coupling.

I det i fig. 2 viste eksempel har hver laske 5 og 5' en del, 25 der i vandret snit er firkantet, og som er forbundet med den respektive søjle 2 eller 2', hvilken del udgør en forlængelse af en del med trekantet tværsnit i vandret plan svarende praktisk taget til halvdelen af det nævnte firkantede tværsnit. Mere detailleret er fladerne 8' og 9 anbragt i de lodrette planer, som skærer 30 de to modstående hjørnekanter af de respektive søjler 2 og 2', og fladerne 8 og 9' befinder sig lidt forskudt til samme side i forhold til disse lodrette planer. De to forbindelseslasker 5 og 5' er således ikke fuldstændigt identiske, idet det trekantede tværsnit i lasken 5' er en smule større end det tilsvaren-35 de trekantede tværsnit i lasken 5, som det fremgår af fig. 3.In the embodiment of FIG. 2, each groove 5 and 5 'has a portion 25 which is square in horizontal section and connected to the respective column 2 or 2', which portion is an extension of a portion of triangular cross-section in the horizontal plane corresponding practically taken to half of said square cross section. More in detail, the faces 8 'and 9' are arranged in the vertical planes which intersect the two opposite corner edges of the respective columns 2 and 2 ', and the faces 8 and 9' are slightly offset to the same side with respect to these vertical planes. Thus, the two connecting lugs 5 and 5 'are not completely identical in that the triangular cross-section of the lug 5' is slightly larger than the corresponding triangular cross-section of the lug 5, as shown in FIG. Third
Det er imidlertid muligt at give laskerne 5 og 5' en lidt ændret udformning, som det fremgår af fig. 4, for derved at tilvejebringe en kobling ved hjælp af to helt identiske lasker, hvilket er fordelagtigt af fabrikationshensyn.However, it is possible to give the lasers 5 and 5 'a slightly altered design, as can be seen in FIG. 4, thereby providing a coupling by means of two completely identical lugs, which is advantageous for fabrication purposes.
145490 6 I den i fig. 3 og 4 viste udførelsesform er formen for laskerne 5 og 5' bestemt til en diagonalmontage af låsekilen 6 i forhold til det firkantede tværsnit af søjlerne 2 og 2'. Der kan også komme en anden udformning på tale, som den i fig. 5 viste, til 5 montage af låsekilen 6 parallelt med en af søjlernes sideflader, eller sagt med andre ord langs en median i det firkantede, vandrette tværsnit.In the embodiment of FIG. 3 and 4, the shape of the lugs 5 and 5 'is intended for diagonal mounting of the lock wedge 6 relative to the square cross-section of columns 2 and 2'. There may also be another embodiment of speech, such as the one shown in FIG. 5 for mounting the lock wedge 6 parallel to one of the pillars' side surfaces, or in other words, along a median of the square horizontal cross section.
Fig. 6 og 7 er snitbilleder, der viser de to søjler 2 og 2' samlet, jfr. den i fig. 5 viste udførelsesform, fordi denne er 10 simpel at afbilde. I denne stilling er centreringstappen 10 på lasken 5 indført i taphullet 11' i lasken 5',og omvendt er centreringstappen 10' på lasken 5' indført i taphullet 11 i lasken 5.FIG. 6 and 7 are sectional views showing the two columns 2 and 2 'together, cf. FIG. 5, because it is 10 simple to view. In this position, the centering pin 10 of the lug 5 is inserted into the tap hole 11 'of the lug 5', and conversely, the centering tab 10 'of the lug 5' is inserted into the lug hole 11 of the lug 5.
Det fremspringende parti beliggende øverst på lasken 5 15 ligger an mod det øvre, som bryst tjenende parti, med firkantet tværsnit af lasken 5',og fladen 9 på dette fremspringende parti befinder sig praktisk taget sammenfaldende med fladen 8' på lasken 5'. Det fremspringende parti nederst på lasken 5' er ligeledes i anlæg mod det nedre,som bryst tjenende parti,med 20 firkantet tværsnit på lasken 5, og fladen 9' på dette fremspringende parti befinder sig praktisk taget sammenfaldende med fladen 8 på lasken 5.-The protruding portion located at the top of the groove 5 15 abuts the upper breast-like portion with a square cross-section of the groove 5 ', and the surface 9 of this protruding portion is substantially coincident with the surface 8' of the groove 5 '. The protruding portion at the bottom of the groove 5 'also abuts the lower, breast-serving portion, having 20 square cross-sections on the groove 5, and the surface 9' of this protruding portion is substantially coincident with the surface 8 of the groove 5.-
De to skråflader 7 og 7', som konvergerer mod hinanden, samt de to lodrette parallelle flader 9 og 9', der er beliggende 25 overfor hinanden, afgrænser tilsammen en åbning 12 med rektangulært tværsnit, i hvilken låsekilen 6 er indsat. Sidstnævnte har en form og dimensioner, som svarer til åbningen 12's, d.v.s. den har en nedre skråflade 13 og en øvre skråflade 13', som har hældninger svarende til fladerne 7' og 7 på de to lasker, som 30 er forbundet med de lodrette parallelle flader.The two oblique faces 7 and 7 'converging towards each other, as well as the two vertical parallel faces 9 and 9' facing each other, together define an opening 12 of rectangular cross-section into which the lock wedge 6 is inserted. The latter has a shape and dimensions corresponding to the opening 12, i.e. it has a lower inclined surface 13 and an upper inclined surface 13 'which has slopes corresponding to the surfaces 7' and 7 of the two lugs 30 connected to the vertical parallel surfaces.
Den smalleste ende af låsekilen 6 er forlænget med en gevin-forsynet stang 14, hvorpå der er skruet en møtrik 15 til spænding og låsning af låsekilen, hvilket under anvendelse af en underlagsskive 16, der ligger an mod de to lasker 5 og 5', gør det 35 muligt at indføre en forspænding i koblingen. Denne forspænding forhindrer klapren eller vrikning af koblingen og sikrer derved koblingen stor pålidelighed.The narrower end of the lock wedge 6 is extended with a threaded rod 14, on which is screwed a nut 15 for tensioning and locking the lock wedge, using a washer 16 which abuts the two lugs 5 and 5 '. makes it possible to insert a bias into the coupling. This bias prevents clutching or twisting of the clutch, thereby ensuring high clutch reliability.
Fig. 8-11 viser efter hinanden følgende faser under samlingen af koblingen, hvor det viste eksempel svarer til den i fig.4 145490 7 viste udførelsesform, hvor låsekilen 6 er anbragt diagonalt, og hvor laskerne 5 og 5' er helt identiske.FIG. 8-11 show successive phases during the assembly of the coupling, the example shown corresponds to the embodiment shown in Fig. 4, where the lock wedge 6 is arranged diagonally and where the lugs 5 and 5 'are completely identical.
I den første i fig. 8 viste fase er der vist de søjler 2 -> og 2", som skal samles, hvor den ene befinder sig over den anden, 5 hvor laskerne 5 og 5' er indsat i hinanden, men ikke bragt- i indbyrdes berøring, idet centreringstappen 10 på lasken 5-befinder sig under undersiden af lasken 5', og centreringstappen.In the first of FIG. 8 shows the columns 2 -> and 2 "to be assembled where one is above the other, 5 where the lugs 5 and 5 'are inserted into each other but not brought into contact, the centering pin 10 of the groove 5 is located below the bottom of the groove 5 ', and the centering pin.
10 på lasken 5' befinder sig ovenover oversiden af lasken 5. Skråfladen 7 på lasken 5 befinder sig nedadvendt ovenover den^ 10 opadvendte skråflade 7' på lasken 5', hvilke to flader ikke kom- ' 1 mer til at støde mod hinanden. De lodrette flader 8 og 9 på lasken 5 er parallelle med de tilsvarende flader 8' og 9' på lasken 5', men er ikke i berøring med hinanden.10 of the groove 5 'is located above the top of the groove 5. The bevel surface 7 of the groove 5 is downwardly above the ^ 10 upwardly sloping surface 7' of the groove 5 ', which two surfaces will not abut. The vertical faces 8 and 9 of the groove 5 are parallel to the corresponding faces 8 'and 9' of the groove 5 ', but are not in contact with each other.
Den efterfølgende i fig. 9 viste fase består i vandret at 15 forskyde elementet, som bærer lasken 5f, i retning af pilen 17 mod lasken 5 for at bringe fladerne 8' og 9* på lasken 5’ i berøring med de tilsvarende flader 8 og 9 på lasken 5. Centreringstappen 10 på lasken 5 kommer derved til at befinde sig lodret flugtende med taphullet 11' i lasken 5‘. Centreringstappen 10* 20 på lasken 5' kommer ligeledes til at befinde sig lodret flugtende med taphullet 11 i lasken 5.The following in FIG. 9, in the horizontal position, 15 is to displace the member carrying the load 5f in the direction of the arrow 17 towards the load 5 to bring the surfaces 8 'and 9 * of the load 5' into contact with the corresponding surfaces 8 and 9 of the load 5. The centering pin 10 of the lug 5 will thereby be vertically flush with the tap hole 11 'in the lug 5'. The centering pin 10 * 20 on the groove 5 'will also be vertically flush with the pin hole 11 in the groove 5.
Derpå sænkes elementet, som bærer lasken 5', som vist ved en pil 18 i fig. 10. Under denne bevægelse trænger centreringstappene 10 og 10' ind i de tilsvarende taphuller 11' og 11 støttet 25 af en styring, der tilvejebringes af rejfninger 19 og 19' på enderne af tappene, henholdsvis 10 og 10', og af andre rejfninger 20 og 20' i mundingerne til taphullerne, henholdsvis 11 og 11'. Lasken 5' bliver derved sænket og samtidigt centreret i forhold til lasken 5, indtil det fremspringende parti nederst 30 på lasken 5' ligger an mod det øvre, med firkantet tværsnit forsynede parti på lasken 5. - I denne stilling, som er vist i fig. 10 og 11, er laskerne 5 og 5* endeligt anbragt i forhold til hinanden, og deres flader 1,1',9 og 9' afgrænser åbningen 12, i hvilken låsekilen ‘6 kan 35 anbringes.Then, the member carrying the load 5 'is lowered, as shown by an arrow 18 in FIG. 10. During this movement, the centering pins 10 and 10 'penetrate into the corresponding pin holes 11' and 11 supported 25 by a guide provided by grooves 19 and 19 'at the ends of the pins, 10 and 10', respectively, and by other grooves 20 and 20 'in the mouths of the tap holes 11 and 11', respectively. The slab 5 'is thereby lowered and simultaneously centered relative to the slab 5 until the protruding portion at the bottom 30 of the slab 5' abuts the upper, square cross-sectional portion of the slab 5. - In this position shown in FIG. . 10 and 11, the lugs 5 and 5 * are finally disposed relative to each other, and their surfaces 1,1 ', 9 and 9' define the opening 12 into which the locking wedge '6 can be placed.
Denne låsekile indføres vandret som vist ved en pil 21 i fig. 11. Derpå anbringes underlagsskiven 16 og møtrikken 15 på den gevindforsynede stang 14 på låsekilen, og møtrikken 13 spændesThis lock wedge is inserted horizontally as shown by an arrow 21 in FIG. 11. Then the washer 16 and the nut 15 are placed on the threaded rod 14 on the locking wedge and the nut 13 is tightened.

8 til sidst for samtidigt at sikre korrekt anbringelse af låsekilen 6 i bunden af åbningen 12, spænding af låsekilen med kontrollerbar kraft og bibeholdelse af denne forspændingskraft under brugen.8, at the same time, to ensure proper placement of the locking wedge 6 at the bottom of the opening 12, tensioning the locking wedge with controllable force and maintaining this biasing force during use.
5 Den kontrollerbare trækkraft i låsekilen 6, som opnås ved at føre denne frem i åbningen 12, søger kraftigt at adskille laskerne ved virkningen af skråfladerne 13 og 13' på låsekilen mod skråfladerne 7 og 7' på de to lasker. Låsekilen frembringer således en væsentlig forspænding i koblingen. Låsekilens trækkraft 10 og dens flades hældning må vælges på passende måde for at begrænse forspændingskraften til en værdi, der sikrer koblingen fuldstændig sikkerhed, samtidig med at senere demontage tillades.5 The controllable pulling force in the lock wedge 6, which is obtained by advancing it in the opening 12, seeks to severely separate the latches by the action of the sloping surfaces 13 and 13 'of the latching wedge against the sloping surfaces 7 and 7' of the two latches. Thus, the locking wedge produces a substantial bias in the coupling. The traction force 10 of the locking wedge and the inclination of its surface must be appropriately selected to limit the biasing force to a value which guarantees complete safety of the coupling, while permitting later dismantling.
Spændingen af låsekilen 6 sikrer endvidere, at endefladerne på de to lasker 5 og 5' ligger bedst muligt indbyrdes an, d.v.s.The tension of the lock wedge 6 further ensures that the end faces of the two lugs 5 and 5 'are mutually compatible, i.e.
15 at fladen beliggende ved enden af den med det trekantede tværsnit forsynede del ligger bedst muligt an mod den som bryst tjenende flade, der er parallel med den med firkantet tværsnit forsynede del på den anden laske. Disse anlægsflader tillader således direkte overføring af trykkræfter via laskernes indbyrdes berøring, og 20 den tilsluttende anbringelse af fladerne mod hinanden tillader også den bedst mulige hensyntagen til koblingens dimensioner og parallelitet.15, the surface located at the end of the triangular cross-sectional portion is as close as possible to the breast-serving surface parallel to the square-sectional section of the second slab. These abutment surfaces thus allow direct transfer of compressive forces via the contact of the lasers, and the subsequent application of the abutments to each other also allows the best possible consideration of the dimensions and parallelism of the coupling.
Den symmetriske hældning af fladerne 13 og 13' på låsekilen 6 i det netop betragtede eksempel har den fordel at tillade 25 samling ved hjælp af to fuldstændigt identiske lasker. Hvis man ikke har brug for denne fabrikationsfordel, kan man også anvende en låsekile med enkelt-hældning eller med dobbelt-hæld-ning, men asymmetrisk.The symmetrical inclination of the faces 13 and 13 'of the lock wedge 6 in the example just considered has the advantage of allowing 25 assembly by means of two completely identical loops. If you do not need this fabrication advantage, you can also use a single-tilt or double-tilt lock wedge, but asymmetrical.
Det rektangulære tværsnit af låsekilen 6, som er den mest 30 simple udførelsesform, kan også erstattes af et tværsnit med parallelogramform eller med et cirkulært tværsnit. Fig. 15 og 16 viser en låsekile med parallelogramformet tværsnit set fra siden og fra enden. Låsekilens nedre og øvre flader 13 og 13' har i dette tilfælde en dobbelt-hældning, medens de øvrige 35 flader forbliver lodrette. Denne udformning, som er vanskeligere at fremstille, har den fordel, at den overflødiggør centreringstappene 10 og 10* som følge af, at dobbelt-hældningen, henholdsvis i længderetningen og tværretningen, for fladerne 13 og 13' 145490 9 bevirker en tilspænding af lasken 5' mod lasken 5. Såfremt man vælger et cirkulært tværsnit; fører dette til en låsekile med konisk form, som ikke er vist, men som er let at forestille sig.The rectangular cross-section of the lock wedge 6, which is the most simple embodiment, can also be replaced by a parallelogram-shaped cross-section or with a circular cross-section. FIG. Figures 15 and 16 show a side wedge and a side view of the parallelogram shaped cross-section. In this case, the lower and upper faces 13 and 13 'of the lock wedge have a double slope, while the other 35 faces remain vertical. This design, which is more difficult to manufacture, has the advantage of overlapping the centering pins 10 and 10 * because the double inclination, respectively longitudinally and transversely, of the surfaces 13 and 13 'causes a tension of the groove 5. 'towards the shank 5. If one chooses a circular cross section; this leads to a conical locking wedge which is not shown, but which is easy to imagine.
Centreringsorganernes udformning kan vare meget forskellig.The design of the centering means can be very different.
5 I de netop her omtalte eksempler er der anvendt tappe 10 og 10' med i hovedsagen cylindrisk form, som rager ud enten fra enderne af laskerne 5 og 5* i det i fig. 2 viste tilfælde, eller fra den del af laskerne 5 og 5', som ligger nærmest den tilhørende søjle 2 eller 2', og som tjener som bryst, således som det er 10 tilfældet i de i fig. 5-11 viste udførelsesformer.5 In the examples just mentioned, pins 10 and 10 'having a generally cylindrical shape projecting either from the ends of the lugs 5 and 5 * in the embodiment of FIG. 2, or from the portion of the lugs 5 and 5 'which are closest to the associated column 2 or 2' and which serve as a breast, as is the case in the cases shown in FIG. 5-11.
Tappene 10 og 10' og de tilsvarende taphuller 11 og 11' kan også have en i hovedsagen konisk form som vist i fig. 17.The pins 10 and 10 'and the corresponding pin holes 11 and 11' may also have a generally tapered shape as shown in FIG. 17th
Under bibeholdelse af praktisk taget samme tværsnit kan man også tilvejebringe centreringsorganer i form af et ribbeformet 15 fremspring 10 og en komplementær rille eller et spor 11, som vist i fig. 18.While maintaining substantially the same cross-section, centering means can also be provided in the form of a rib-shaped projection 10 and a complementary groove or groove 11, as shown in FIG. 18th
I en anden udførelsesform kan den øvre flade 22 på lasken 5, og laskens mod skråfladen 7 vendende, som bryst tjenende flade 23 bibringes en vis fælles hældning, som vist i fig. 19. Denne 20 foranstaltning er på en vis måde analog med den i fig. 15 og 16 viste, idet den sikrer tilspænding mod lasken 5 af lasken 5',som er udformet på samme måde, når låsekilen 6 er anbragt på plads, og det skal yderligere bemærkes, at hældningen for fladerne 22 og 23 ikke forhindrer, at de udgør de anlægsflader, der sikrer 25 overføringen af konstruktionens trykkræfter.In another embodiment, the upper surface 22 of the latch 5 and the lashing surface facing the inclined surface 7 as a breast 23 may be imparted to some common inclination, as shown in FIG. 19. This measure is in some sense analogous to that of FIG. 15 and 16, securing tension against the groove 5 of the groove 5 ', which is formed in the same manner when the locking wedge 6 is placed in place, and it should be further noted that the inclination of the faces 22 and 23 does not prevent the constitute the abutment surfaces which ensure the transfer of the compressive forces of the structure.
Endelig viser fig. 20 en sidste udførelsesform, hvor centreringsorganerne udgøres af en ribbe 24, som er tilvejebragt på foden af lasken 5, men udvendigt anbragt, d.v.s. i forlængelse af den ene sideflade af lasken.Finally, FIG. 20 is a last embodiment in which the centering means is constituted by a rib 24 which is provided on the foot of the lug 5 but externally disposed, i.e. by extension of one side surface of the bottle.
30 Koblingen er især velegnet ved sammenkobling af elemen ter, hvor søjlerne har samme tværsnit, således som det er tilfældet i de i fig. 1-11 viste eksempler, og tillader tilvejebringelse af forb fidel s eskoblinger ved hjælp af to identiske lasker 5 og 5', hvis fordele er fremhævet i det foregående. Alligevel 35 tillader anbringelsen af låsekilen 6 diagonalt også samling ved hjælp af det samme princip af to søjler 2 og 2' med forskelligt tværsnit som vist i fig. 12 samt 13 og 14, hvor den i fig. 12 viste udførelsesform er set henholdsvis i retning af pilen F1 og F2. I det sidste tilfælde er de to lasker 5 og 5' ikke nøjagtigtThe coupling is particularly suitable for coupling elements where the columns have the same cross-section, as is the case in the figures shown in FIG. 1-11, and allows the provision of prohibitive couplings by means of two identical loops 5 and 5 ', the advantages of which have been highlighted above. Yet, the placement of the lock wedge 6 diagonally also allows assembly by the same principle of two columns 2 and 2 'of different cross sections as shown in FIG. 12 as well as 13 and 14, where in FIG. 12 is seen in the direction of arrow F1 and F2 respectively. In the latter case, the two loops 5 and 5 'are not accurate
