FESTE FOR EN KOMPOSITTMAST TIL EN OPPOVER-RAGENDE KONISK FORMET FESTESØYLE MED EN RINGFORMET FLENS, OG FREMGANGAMÅTE FOR Å FESTE EN KOMPOSITTMAST MED EN SLIK KONISK FORMET FESTESØYLE TIL GRUNNEN. ATTACHMENT OF A COMPOSITE MAST TO AN UPPER-PROJECTING CONICAL ATTACHING POST WITH AN RING-SHAPED FLANGE, AND PROCEDURE FOR ATTACHING A COMPOSITE MAST WITH SUCH TAPERED ATTACHING POST TO THE GROUND.
Denne oppfinnelse vedrører et feste for en komposittmast hvor en ringformet flens er forsynt med en i bruksstilling oppover ragende avkortet konisk formet festesøyle som komplementært passer til en komposittmasts nedre parti, og hvor flensen er forsynt med hull for flere fjellbolter hvor fjellboltene er festet til grunnen, idet veggen i den koniske festesøylen har et konisk midtplan. Oppfinnelsen omfatter også en fremgangsmåte for anvendelse av samme. This invention relates to an attachment for a composite mast where an annular flange is provided with a truncated conical-shaped attachment column projecting upwards in the use position which complementarily fits a composite mast's lower part, and where the flange is provided with holes for several rock bolts where the rock bolts are attached to the ground, in that the wall of the conical fixing column has a conical mid-plane. The invention also includes a method for using the same.
Med konisk midtplan menes i denne sammenheng et konisk plan som er dannet av alle midtpunktene i det plateformede materialet som konen er fremstilt av. Conical center plane in this context means a conical plane which is formed by all the center points in the plate-shaped material from which the cone is made.
Det er kjent å feste komposittmaster til grunnen ved å posisjonere komposittmasten i et oppgravd hull i bakken hvor tilbakefylt masse holder komposittmasten i ønsket stilling. Erfaring viser at det kan være vanskelig å få tilstrekkelig innbyggingsstyrke uten ytterligere tiltak. Et vanlig tiltak er å anvende et foringsrør som masten settes i. Bruk av foringsrør betinger ofte at det fylles for eksempel singel mellom foringsrøret og komposittmasten. Det kan være en ulempe ved denne festemåten at det gjøres relativt store inngrep i naturen og at det medfører mye transport av maskiner, utstyr og materialer i terrenget omkring. It is known to attach composite masts to the ground by positioning the composite mast in an excavated hole in the ground where backfilled mass holds the composite mast in the desired position. Experience shows that it can be difficult to obtain sufficient built-in strength without additional measures. A common measure is to use a casing in which the mast is placed. The use of casing often requires that shingle is filled between the casing and the composite mast, for example. It can be a disadvantage of this method of attachment that relatively large interventions are made in nature and that it entails a lot of transport of machines, equipment and materials in the surrounding terrain.
NO 343861 beskriver en festemetode hvor det bores en slisse i bakken og hvor en adapter gyses fast i slissen. Adapterens øvre del passer til komposittmastens nedre parti. Denne festemetoden medfører ubetydelig inngrep i naturen, men kan være tidkrevende. NO 343861 describes a fastening method where a slot is drilled in the ground and where an adapter is screwed into the slot. The upper part of the adapter fits the lower part of the composite mast. This fastening method involves negligible interference with nature, but can be time-consuming.
Det er videre kjent å feste en konisk festesøyle til en ringformet flens hvor festesøylen passer til komposittmastens nedre parti. Flensen er festet til grunnen ved hjelp av fjellbolter som befinner seg utenfor den koniske festesøylens diameter. Det kreves relativt grove materialdimensjoner ved anvendelse av denne løsningen fordi overføringen av krefter mellom festesøylen og fjellboltene er ugunstig. It is also known to attach a conical fixing column to an annular flange where the fixing column fits the lower part of the composite mast. The flange is fixed to the ground by means of rock bolts located outside the diameter of the conical fixing column. Relatively coarse material dimensions are required when using this solution because the transfer of forces between the fixing column and the rock bolts is unfavorable.
Fra NO 20160271 er det kjent en festeanordning og fremgangsmåte for fastgjøring av en hul, konisk formet komposittmast til grunnen, idet festeanordningen i form av en oppover-ragende festesøyle/konisk formet søyle med en ringformet flens er festet til grunnen hjelp av bolter. From NO 20160271, a fastening device and method for fastening a hollow, conically shaped composite mast to the ground is known, the fastening device in the form of a projecting fastening column/conical-shaped column with an annular flange being fixed to the ground by means of bolts.
KR 100684255 beskriver en bunnplatekobling for en lyktestolpe hvor bunnplaten er boltet fast til bakken. KR 100684255 describes a base plate connection for a lamppost where the base plate is bolted to the ground.
Ved feste av master i tre er det kjent å anvende flere festevinkler som er festet til grunnen og som rager oppover langs masten. Det anvendes gjennomgående bolter mellom to motstående festevinkler til å holde masten fast. Dette systemet er også brukt på hule komposittmaster. Det er imidlertid en ulempe at mastene, grunnet tiltrekningskraften i de gjennomgående boltene, blir urunde. En konsekvens av dette kan være at mastens posisjon vil avvike fra gjeldende toleranse eller krav. When attaching wooden masts, it is known to use several attachment angles which are attached to the ground and which project upwards along the mast. Through-bolts are used between two opposite attachment angles to hold the mast firmly. This system is also used on hollow composite masts. However, it is a disadvantage that the masts, due to the attractive force of the through bolts, become unrounded. A consequence of this may be that the position of the mast will deviate from the current tolerance or requirement.
Oppfinnelsen har til formål å avhjelpe eller å redusere i det minste én av ulempene ved kjent teknikk, eller i det minste å skaffe til veie et nyttig alternativ til kjent teknikk. The purpose of the invention is to remedy or to reduce at least one of the disadvantages of known technology, or at least to provide a useful alternative to known technology.
Formålet oppnås ved trekkene som er angitt i nedenstående beskrivelse og i de etterfølgende patentkravene. The purpose is achieved by the features indicated in the description below and in the subsequent patent claims.
Oppfinnelsen er definert av de selvstendige patentkravene/det selvstendige patentkravet. De uselvstendige kravene definerer fordelaktige utførelser av oppfinnelsen. The invention is defined by the independent patent claims/the independent patent claim. The independent claims define advantageous embodiments of the invention.
Oppfinnelsen vedrører mer spesifikt et feste for en komposittmast hvor en ringformet flens er forsynt med en i bruksstilling oppover-ragende konisk formet festesøyle som komplementært passer til komposittmastens nedre parti, og hvor flensen er forsynt med hull for flere fjellbolter som er festet til grunnen, idet veggen i den koniske festesøylen har et konisk midtplan, og hvor fjellbolten står i en utsparing i festesøylen, og hvor fjellboltens senterlinje har et skjæringspunkt med det koniske midtplanet i eller nær flensen. The invention relates more specifically to an attachment for a composite mast where a ring-shaped flange is provided with an upwardly projecting conical attachment column in the use position which complementarily fits the lower part of the composite mast, and where the flange is provided with holes for several rock bolts which are attached to the ground, as the wall of the conical fixing column has a conical mid-plane, and where the rock bolt stands in a recess in the fixing column, and where the center line of the rock bolt has an intersection with the conical mid-plane in or near the flange.
Denne plassering av det nevnte skjæringspunktet bevirker at vridning i flensmaterialet som følge av at det er en avstand mellom fjellboltens senterlinje og det koniske midtplan er tilnærmet eliminert. This location of the aforementioned intersection means that twisting in the flange material as a result of there being a distance between the rock bolt's center line and the conical center plane is virtually eliminated.
Ved utbøying av komposittmasten kan disse vridningskrefter i flensen være betydelige dersom fjellboltene befinner seg utenfor festesøylen i flensen. When the composite mast is bent, these twisting forces in the flange can be significant if the rock bolts are located outside the fixing column in the flange.
Feste som ovenfor hvor fjellboltens senterlinje har skjæringspunktet med det koniske midtplanet innenfor 10 cm avstand fra flensen. Fasten as above where the rock bolt's center line has the point of intersection with the conical center plane within 10 cm of the flange.
Det tilstrebes å holde skjæringspunktet innenfor flensmaterialets tykkelse. Praktiske forhold så som klaring mellom fjellbolt og hull i flensen samt andre produksjonstekniske forhold gjør at dette vanskelig alltid kan oppnås. Dersom skjæringspunktet befinner seg innenfor en avstand på 10 cm fra flensen, er dette tilfredsstillende. Større avvik kan forekomme uten at oppfinnelsens fordeler i betydelig grad svekkes. Efforts are made to keep the point of intersection within the thickness of the flange material. Practical conditions such as clearance between rock bolt and hole in the flange as well as other production technical conditions make this difficult to always achieve. If the point of intersection is within a distance of 10 cm from the flange, this is satisfactory. Larger deviations can occur without the invention's advantages being weakened to a significant extent.
Feste som ovenfor hvor konen i utsparingen, i det minste på en del av denne, kan være forsynt med en forsterkingsplate. Forsterkingsplanten er fortrinnsvis anordnet vinkelrett mot materialet i konen. Fasten as above where the cone in the recess, at least on part of it, can be provided with a reinforcement plate. The reinforcement plant is preferably arranged perpendicular to the material in the cone.
Feste som ovenfor hvor flensen befinner seg mellom en øvre fjellboltmutter og en nedre fjellboltmutter og hvor det i det minste mellom den øvre fjellboltmutteren og flensen, eller mellom den nedre fjellboltmutteren og flensen kan være anordnet en lastfordelingsplate. Fasten as above where the flange is located between an upper rock bolt nut and a lower rock bolt nut and where at least a load distribution plate can be arranged between the upper rock bolt nut and the flange, or between the lower rock bolt nut and the flange.
Både forsterkingsplaten og lastfordelingsplatene anvendes for å spre lasten. Derved reduseres lastkonsentrasjonene, noe som muliggjør ytterligere reduksjon i materialtykkelse. Both the reinforcement plate and the load distribution plates are used to spread the load. Thereby, the load concentrations are reduced, which enables a further reduction in material thickness.
I et andre aspekt vedrører oppfinnelsen mer spesifikt en fremgangsmåte for å feste en komposittmast til grunnen hvor en ringformet flens er forsynt med en i bruksstilling oppover ragende konisk formet festesøyle som komplementært passer til komposittmastens nedre parti, og hvor flensen er forsynt med hull for flere fjellbolter, og hvor fjellboltene er festet til grunnen, idet veggen i den koniske festesøylen har et konisk midtplan, og hvor fremgangsmåten omfatter at fjellbolten anbringes i en utsparing i den koniske festesøylen relativt det koniske midtplanet slik at det etableres et skjæringspunkt mellom fjellboltens senterlinje og det koniske midtplanet i eller nær flensen. In a second aspect, the invention relates more specifically to a method for fixing a composite mast to the ground, where an annular flange is provided with a conically shaped fixing column projecting upwards in the use position which complementarily fits the lower part of the composite mast, and where the flange is provided with holes for several rock bolts , and where the rock bolts are attached to the ground, as the wall in the conical fixing column has a conical mid-plane, and where the method comprises placing the rock bolt in a recess in the conical fixing column relative to the conical mid-plane so that an intersection is established between the center line of the rock bolt and the conical the midplane in or near the flange.
Forsøk viser at festet ifølge oppfinnelsen sammenlignet med lignende fester, har en vesentlig større styrke ved bruk av like materialtykkelser. Tests show that the fastener according to the invention, compared to similar fasteners, has a significantly greater strength when using similar material thicknesses.
Ofte handteres fester som dette i områder som er vanskelig tilgjengelige. Når løfteutstyr ikke er tilgjengelig, må manuell håndtering benyttes. Det er innlysende at en reduksjon i vekt er av stor betydning. Often parties like this are handled in areas that are difficult to access. When lifting equipment is not available, manual handling must be used. It is obvious that a reduction in weight is of great importance.
I det etterfølgende beskrives eksempler på foretrukne utførelsesformer som er anskueliggjort på medfølgende tegninger, hvor: In the following, examples of preferred embodiments are described which are illustrated in the accompanying drawings, where:
Fig.1 et feste for en komposittmast i en enkel utførelse; Fig.1 an attachment for a composite mast in a simple design;
Fig.2 festet for en komposittmast i en foretrukket utførelse; Fig.2 fixed for a composite mast in a preferred embodiment;
Fig.3 viser i større målestokk et snitt I-I i fig.1; og Fig.3 shows on a larger scale a section I-I in Fig.1; and
Fig.4 viser i større målestokk et snitt II-II i fig.2. Fig.4 shows on a larger scale a section II-II in fig.2.
På figurene betegner henvisingstallet 1 et feste for en komposittmast 4. Festet 1 omfatter en flens 6 som er forsynt med en fast, konsentrisk, i bruksstilling oppover-ragende konisk festesøyle 8. Den koniske festesøylen 8 passer komplementært til komposittmastens 4 nedre parti 10. In the figures, the reference numeral 1 denotes an attachment for a composite mast 4. The attachment 1 comprises a flange 6 which is provided with a fixed, concentric, conical attachment column 8 projecting upwards in the position of use. The conical attachment column 8 fits complementary to the lower part 10 of the composite mast 4.
Et antall fjellbolter 12 som er festet i grunnen 14 forløper gjennom respektive hull 16 i flensen 6. En øvre fjellboltmutter18 befinner seg over flensen 6 og en nedre fjellboltmutter 20 befinner seg under flensen 6. Flensen 6 er klemt mellom mutterne 18 og 20. Hver fjellbolt 12 har en senterlinje 22. A number of rock bolts 12 fixed in the base 14 extend through respective holes 16 in the flange 6. An upper rock bolt nut 18 is located above the flange 6 and a lower rock bolt nut 20 is located below the flange 6. The flange 6 is clamped between the nuts 18 and 20. Each rock bolt 12 has a center line 22.
Den koniske festesøylens 8 veggmateriale er relativt tynt og er fortrinnsvis fremstilt i et metall. Midtpunktene i materialet danner et konisk midtplan 24 illustrert ved en linje i fig.3 og 4. The wall material of the conical fastening column 8 is relatively thin and is preferably made of a metal. The center points in the material form a conical center plane 24 illustrated by a line in fig.3 and 4.
Fjelboltene 12 er anbrakt slik at senterlinjene 22 skjærer gjennom det koniske midtplanet 24 i et skjæringspunkt 26 nær flensen 6. Skjæringspunkt 26 er vist i fig.3 og 4. Fortrinnsvis bør skjæringspunktet 26 mellom senterlinjen 22 og det koniske midtplanet 24 være i flensen 6. The rock bolts 12 are placed so that the center lines 22 cut through the conical center plane 24 at an intersection point 26 close to the flange 6. Intersection point 26 is shown in fig.3 and 4. Preferably, the intersection point 26 between the center line 22 and the conical center plane 24 should be in the flange 6.
Unøyaktigheter i boltplassering og andre forhold bevirker at skjæringspunktet 26 kan være noe høyere eller lavere i forhold til flensen 6. Inaccuracies in bolt placement and other conditions cause the intersection point 26 to be somewhat higher or lower in relation to the flange 6.
Det er laget en utsparing 28 i den koniske festesøylen 8 for å gi plass til fjellbolten 12 og den øvre fjellboltmutteren 18. A recess 28 has been made in the conical fastening column 8 to provide space for the mountain bolt 12 and the upper mountain bolt nut 18.
Ved å anbringe fjellbolten12 i den viste posisjonen relativt festesøylen 8, oppstår det ved bøymoment i komposittmasten 4, bare ubetydelige vridningskrefter i flensen 6 sammenlignet med når fjellbolten 12 befinner seg utenfor festesøylen 8. By placing the rock bolt 12 in the position shown relative to the fixing column 8, only negligible twisting forces occur in the flange 6 in the case of bending moment in the composite mast 4 compared to when the rock bolt 12 is located outside the fixing column 8.
I fig.2 og 4 vises en foretrukket utførelsesform hvor det er festet en forsterkingsplate 30 i utsparingen 28. Det er også anordnet lastfordelingsplater 32 både mellom den øvre fjellboltmutteren18 og flensen 6, eller mellom den nedre fjellboltmutteren 20 og flensen 6 In fig.2 and 4, a preferred embodiment is shown where a reinforcement plate 30 is fixed in the recess 28. Load distribution plates 32 are also arranged both between the upper rock bolt nut 18 and the flange 6, or between the lower rock bolt nut 20 and the flange 6
Hensikten med forsterkingsplaten 30 og lastfordelingsplatene 32 er å fordele lastene bedre for derved å ytterligere kunne redusere materialdimensjonene på flensen 6 og festesøylen 8. The purpose of the reinforcement plate 30 and the load distribution plates 32 is to distribute the loads better in order to further reduce the material dimensions of the flange 6 and the fixing column 8.
