Description

Den foreliggende oppfinnelse vedrører en anordning til festing av et oppadragende, langstrakt element, såsom en søyle, stolpe eller skorstein, med dets nedre ende til en sokkels øvre flate, idet elementets nedre ende er festet til et flensformet organ som rager stort sett radialt og som er festet til sokkelen. The present invention relates to a device for attaching an upwardly extending, elongated element, such as a column, post or chimney, with its lower end to the upper surface of a plinth, the element's lower end being attached to a flange-shaped member which projects largely radially and which is attached to the base.

Hos en slik festeanordning må man ta særlig hensyn tilParticular attention must be paid to such a fastening device

at når elementet er belastet med en ytre kraft, f.eks. vindtrykk, oppstår det i elementet strekkspenninger som må opptas av festeorganet ved sokkelen. that when the element is loaded with an external force, e.g. wind pressure, tensile stresses arise in the element which must be taken up by the fastening element at the plinth.

Hittil er det flensformete organ festet direkte til sokkelen plant på denne ved hjelp av festeorganer, særlig når sokkelen er dannet av en betongplate, ved hjelp av festebolter som er innstøpt i betongen. Hitherto, the flange-shaped member has been attached directly to the plinth flat on it by means of fastening means, particularly when the plinth is formed from a concrete slab, by means of fastening bolts embedded in the concrete.

Dette medfører at når det opptrer strekkspenninger i det oppadragende element utsettes festeorganet, særlig festeboltene, for høye, varierende belastninger, slik at det er fare for at boltene bryter sammen eller trekkes løs fra betongen. Dessuten kan det utvikles høye bøyemomenter i det flensformete organ, This means that when tensile stresses occur in the supporting element, the fixing device, in particular the fixing bolts, is subjected to high, varying loads, so that there is a risk of the bolts breaking or being pulled loose from the concrete. Furthermore, high bending moments can develop in the flange-shaped member,

noe som gjør det viktig at det mellom det flensformete organwhich makes it important that between the flange-shaped organ

og det oppadragende element er anordnet monteringsplater forand mounting plates are provided for the upwardly extending element

å motvirke forvridninger, hvorved festeanordningen blir kompli-sert . to counteract distortions, whereby the fastening device becomes complicated.

Formålet med oppfinnelsen er å frembringe en særlig hen-siktsmessig anordning av den ovennevnte type. The purpose of the invention is to produce a particularly appropriate device of the above type.

Dette er oppnådd ved at det flensformete organ er anordnetThis has been achieved by the fact that the flange-shaped body is arranged

i avstand fra sokkelen og hviler fritt ved dets endekanter på sokkelens øvre flate via minst ett par understøttelseselementer, som er innbyrdes atskilt i radial retning, og at et organ står i inngrep med sokkelen for utøvelse av minst en forspenningskraft på det flensformete organ, slik at dette blir trykket an mot sokkelen via understøttelseselementene. at a distance from the base and rests freely at its end edges on the upper surface of the base via at least one pair of support elements, which are mutually separated in the radial direction, and that a member engages with the base for exerting at least one biasing force on the flange-shaped member, so that this is pressed against the base via the support elements.

Fortrinnsvis er organet som utøver forspenningskraft dannet av minst én forspent, vertikal stang som med dens ene side står i inngrep med det flensformete organ i et punkt mellom understøt-telseselementene og med dens annen side med sokkelen. Preferably, the member which exerts a prestressing force is formed by at least one prestressed, vertical rod which engages with one side of the flange-shaped member at a point between the support elements and with its other side with the base.

På denne måte utvikles det en forholdsvis stor oppadrettet reaksjonskraft som utøves på det flensformete organ, av forspen-ningskraften i understøttelseselementene, som befinner seg ved festepunktet for det oppadragende element til det flensformete organ, slik at når det utvikles strekkspenninger i det oppadragende element fører disse spenninger utelukkende til en minskning av reaksjonskraften, som kan velges så stor at den aldri vil forsvinne fullstendig, med det resultat at forspenningsorganet som står i inngrep med sokkelen aldri vil bli utsatt for varierende belastninger og at det ikke vil bli dannet bøyemomenter. In this way, a relatively large upward reaction force is developed which is exerted on the flange-shaped body, by the pre-stressing force in the support elements, which are located at the attachment point for the uplifting element to the flange-shaped body, so that when tensile stresses are developed in the uplifting element, these lead stresses exclusively to a reduction of the reaction force, which can be chosen so great that it will never disappear completely, with the result that the prestressing member which is in engagement with the base will never be subjected to varying loads and that no bending moments will be formed.

For å gjøre reaksjonskraften så stor som mulig med en forut-bestemt forspenningskraft, befinner det punkt hvor den forspente stang står i inngrep med det flensformete organ seg fortrinnsvis borte fra midten mellom understøttelseselementene og nærmere understøttelseselementet som det oppadragende element er festet med til det flensformete organ. In order to make the reaction force as large as possible with a predetermined prestressing force, the point where the prestressed rod engages with the flange-shaped member is preferably located away from the center between the support elements and closer to the support element with which the upwardly extending element is attached to the flange-shaped member .

Fortrinnsvis rager hver forspent stang glidbart gjennom sokkelen og det flensformete organ, og hver forspent stang står i inngrep med sokkelens nedre flate og med det flensformete organs øvre flate. Preferably, each biased rod protrudes slidably through the base and the flange-shaped member, and each biased rod engages with the lower surface of the base and with the upper surface of the flange-shaped member.

Fortrinnsvis er sokkelen dannet av en plate av betong i hvis øvre og nedre flater det ifølge oppfinnelsen er lagt en skive som den forspente stang står i inngrep med og som under-støttelseselementet danner anlegg mot respektivt slik at kraften som utøves mot betongen av forspenningen fordeles over et stort område, og det er ikke lenger fare for at betongen skal bryte sammen. Preferably, the plinth is formed by a slab of concrete in whose upper and lower surfaces, according to the invention, a disk is placed with which the prestressed rod engages and against which the support element forms contact, respectively, so that the force exerted against the concrete by the prestress is distributed over a large area, and there is no longer any danger of the concrete breaking down.

Med fordel er hver forspent stang opptatt i betongen og belagt med et materiale som betongen ikke hefter til. Advantageously, each prestressed rod is embedded in the concrete and coated with a material to which the concrete does not adhere.

Idet det er viktig at det flensformete organ rager så nøy-aktig som mulig horisontalt og dessuten at understøttelsesele-mentet uten klaring danner anlegg mot både det flensformete organ og sokkelens øvre flate er understøttelseselementene med fordel kileformete organer som er anordnet mellom sokkelens øvre flate og fremspringende elementer som er festet til det flensformete organ. Ved hjelp av disse flensformete organer jevnes ujevnheter i den øvre flate av sokkelen, særlig en betongplate, ut og det oppnås en understøttelse uten noen form for klaring. Since it is important that the flange-shaped member protrudes as precisely as possible horizontally and furthermore that the support element without clearance forms contact with both the flange-shaped member and the upper surface of the plinth, the support elements are advantageously wedge-shaped members which are arranged between the upper surface of the plinth and protruding elements which are attached to the flange-shaped member. With the help of these flange-shaped bodies, unevenness in the upper surface of the plinth, especially a concrete slab, is smoothed out and a support is achieved without any form of clearance.

Oppfinnelsen vil bli forklart i detalj ved beskrivelseThe invention will be explained in detail by description

av en utførelsesform som er vist i tverrsnitt på den medfølgende tegning. of an embodiment which is shown in cross-section in the accompanying drawing.

Som vist på tegningen er et oppadragende element, f.eks.As shown in the drawing, a pull-up element, e.g.

en skorstein, festet ved sveising ved 2 til et flensformet organ 3. Til det flensformete organ 3, ved dettes kanter, er det festet fremspringende elementer 4 og 5 som hviler fritt på kileformete elementer 6 og 7, som i sin tur hviler fritt på en skive 8 som er innleiret i en plate 9 av betong, som danner sokkelen. a chimney, attached by welding at 2 to a flange-shaped member 3. To the flange-shaped member 3, at its edges, are attached projecting elements 4 and 5 which rest freely on wedge-shaped elements 6 and 7, which in turn rest freely on a disk 8 which is embedded in a slab 9 of concrete, which forms the base.

I betongplatens 9 underside er det innleiret en skive 10A disc 10 is embedded in the underside of the concrete slab 9

i betongen, og med denne står det i inngrep forspenningsstenger 11 og 11' via deres hoder 12 og 12'. Stengene 11 og 11' rager gjennom betongplaten 9 og det flensformete organ 3. Ved dreining av muttere 13, 13', som danner anlegg mot det flensformete organs 3 overside, forspennes forspenningsstengene 11 og 11' slik at det utvikles reaksjonskrefter i understøttelseselementene 4, in the concrete, and prestressing rods 11 and 11' engage with this via their heads 12 and 12'. The rods 11 and 11' protrude through the concrete slab 9 and the flange-shaped member 3. When nuts 13, 13' are turned, which form contact with the upper side of the flange-shaped member 3, the pre-tensioning rods 11 and 11' are prestressed so that reaction forces are developed in the support elements 4,

6 og 5, 7. Som følge av at forspenningsstengene 11 og 11' danner inngrep med det flensformete organ 3 i et punkt som ikke ligger midt mellom understøttelseselementene 4, 6 og 5, 7, men nærmere det oppadragende element 1, vil reaksjonskreftene i understøt-telseselementene 4, 6 være større enn de øvrige reaksjonskrefter. Når det opptrer en strekkspenning i det oppadragende element 6 and 5, 7. As a result of the prestressing rods 11 and 11' forming an engagement with the flange-shaped member 3 at a point which is not located in the middle between the support elements 4, 6 and 5, 7, but closer to the upward-pulling element 1, the reaction forces in the support -the elements 4, 6 be greater than the other reaction forces. When a tensile stress occurs in the uplifting element

I, vil denne kraft utelukkende føre til en minskning av reaksjonskraften i understøttelseselementene 4, 6, og denne reaksjonskraft vil ved riktig valg av 'f orspenningskraf t i f orspenningsstengene II, 11' være så stor at reaksjonskraften aldri vil forsvinne fullstendig, noe som resulterer i at forspenningsstengene 11, I, this force will exclusively lead to a reduction of the reaction force in the support elements 4, 6, and this reaction force will, with the correct choice of the 'prestressing force in the prestressing rods II, 11', be so great that the reaction force will never disappear completely, which results in the bias bars 11,

11' aldri vil bli utsatt for varierende belastninger og at det ikke vil bli utviklet bøyemomenter i det flensformete organ 3. 11' will never be exposed to varying loads and that no bending moments will be developed in the flange-shaped member 3.

Rundt forspenningsstengene 11 og 11' er det anbrakt en slange 14, 14' av et materiale som betongen ikke hefter til, Around the prestressing rods 11 and 11', a hose 14, 14' of a material to which the concrete does not adhere is placed,

slik at stengene 11, 11' står i glideinngrep med betongen.so that the bars 11, 11' are in sliding engagement with the concrete.

Hele hulrommet mellom ytterkanten av det flensformete organ 3 og betongplaten 9 kan fylles med en mørtel som ikke krymper ved herding. The entire cavity between the outer edge of the flange-shaped member 3 and the concrete slab 9 can be filled with a mortar that does not shrink when hardening.
