Description
Fundament for feste av master. Foundation for fixing the mast.
Denne oppfinnelse vedrører et fundament for feste av master, f. eks. master for gatebelysning, for elektriske ledninger, tra-fikkmerker og lignende, idet masten van-ligvis består av stålrør. Oppfinnelsen ved-rører sådanne anordninger som består av et for nedsenkning i jorden bestemt be-tongfundament av i høyderetningen lang-strakt form og med langsgående hull for masten. Ved gater og veier oppstilte master er sterkt utsatt for skade fra kollider-ende kjøretøy og lignende. Det er derfor av interesse, at mastene lett skal kunne skiftes ut samtidig som de skal være lett å montere. Fundamentet er nedsenket i jorden for at det skal unngå skade. Det bør være så sterkt, at det ikke skades og ikke løsner, selv om masten utsettes for slik påvirkning, at den knekker. Fundamenter av jern har vist seg uhensiktsmessige fra forankrings- og styrkesynspunkt, hvorfor man nu søker å fordre fundament av betong, men hittil har det ikke lykkes å fremstille et slikt fundament som fra alle til problemet hørende synspunkter oppfyller sin hensikt på ønskelig måte. Fundamentet ifølge oppfinnelsen, som ved utførte prøver har vist seg å virke på en utmerket måte, utmerker seg hovedsakelig ved, at der omkring hullets øverste del er faststøpt i betonggodset en metallisk forsterkningsring, til hvilken er festet armeringsjern, som strekker seg nedad i fundamentets lengderetning. This invention relates to a foundation for attaching masts, e.g. masts for street lighting, for electric cables, traffic signs and the like, as the mast usually consists of steel pipes. The invention relates to such devices which consist of a concrete foundation intended for immersion in the ground of elongated shape in the height direction and with longitudinal holes for the mast. Masts erected by streets and roads are highly exposed to damage from colliding vehicles and the like. It is therefore of interest that the masts should be easy to replace while also being easy to install. The foundation is sunk into the ground to avoid damage. It should be so strong that it is not damaged and does not come loose, even if the mast is subjected to such an impact that it breaks. Foundations made of iron have proven to be unsuitable from the point of view of anchoring and strength, which is why they are now seeking to demand a foundation made of concrete, but so far it has not succeeded in producing such a foundation which, from all points of view pertaining to the problem, fulfills its purpose in a desirable way. The foundation according to the invention, which has been shown to work in an excellent way in tests carried out, is distinguished mainly by the fact that, around the upper part of the hole, a metallic reinforcement ring is cast into the concrete, to which rebar is attached, which extends downwards in the longitudinal direction of the foundation .
Det er kjent å fremstille fundamenter av betong med nedad konisk avsmalnende hull for en stolpe, idet der ovenpå fundamentets øvre ende festes løsbart en todelt kappe av metallplate, som ved sin øvre halsartede ende er fastspent på stolpen et stykke ovenfor hullet i betonglegemet. Denne kappe er ved muttere løsbart festet til forlengelser av jernstenger, som er inn-støpt i betongen og går gjennom avlange slisser i kappen. En slik kappe kan på grunn av sin stilling, fastspenningsmåten og det tynne plategods, som lett deforme-res, ikke danne en beskyttelse for godset i selve betongfundamentet, om stolpen utsettes for sterk påkjenning. Til forskjell herfra danner den ifølge oppfinnelsen i betonggodset, omkring stolpehullets øvre del innstøpte forsterkningsring en beskyttelse for selve betonggodset, som får nød-vendig styrke ved at forsterkningsringen er forbundet med armeringsjern som for-deler påkjenningene på ringen nedad over store deler av betongfundamentet. It is known to produce concrete foundations with a downwardly conical hole for a post, where a two-part jacket made of sheet metal is releasably attached on top of the upper end of the foundation, which at its upper neck-like end is clamped onto the post some distance above the hole in the concrete body. This cover is releasably attached by nuts to extensions of iron rods, which are embedded in the concrete and pass through oblong slits in the cover. Due to its position, the method of clamping and the thin plate goods, which are easily deformed, such a cover cannot form a protection for the goods in the concrete foundation itself, if the post is subjected to strong stress. In contrast to this, according to the invention, the reinforcing ring embedded in the concrete, around the upper part of the post hole, forms a protection for the concrete itself, which gets the necessary strength by the fact that the reinforcing ring is connected to rebar which distributes the stresses on the ring downwards over large parts of the concrete foundation.
Oppfinnelsen skal forklares nærmere under henvisning til et på tegningen vist utførelseseksempel. Fig. 1 viser fundamentet i vertikalsnitt med en deri innført mast. Fig. 2 viser et snitt gjennom forsterkningsringen i større målestokk enn i fig. 1. The invention shall be explained in more detail with reference to an embodiment shown in the drawing. Fig. 1 shows the foundation in vertical section with a mast inserted therein. Fig. 2 shows a section through the reinforcement ring on a larger scale than in fig. 1.
På tegningen betegner 1 det av betong fremstilte fundamentlegeme, som kan ha sirkulær tverrsnittsform eller eventuelt kantet kontur. Gjennom fundamentet fø-rer i høyderetningen et hull 2 med oventil noe større diameter enn det rør 3, som danner masten. Ved den nedre del 4 er hullet konisk avsmalnende og danner på denne måte et sentrerende sete for mastens nedre ende. 5 betegner eventuelt forekommende sideåpninger i fundamentet for elektriske kabler eller lignende til røret 3. In the drawing, 1 denotes the foundation body made of concrete, which may have a circular cross-sectional shape or possibly an angular contour. A hole 2 with a slightly larger diameter at the top than the pipe 3, which forms the mast, leads through the foundation in the height direction. At the lower part 4, the hole is conically tapered and in this way forms a centering seat for the lower end of the mast. 5 denotes any side openings in the foundation for electrical cables or similar to the pipe 3.
Ved den øvre del av hullet 2 er der i betongen faststøpt en metallisk forsterkningsring eller hylseformet sko 6, som er sveiset sammen med langsgående armeringsjern 7, så at man får en for mekaniske påkjenninger meget motstandsdyktig kon-struksjon. Bare endel av armerings]ernene, f. eks. omtrent halvparten, behøver å strek-ke seg ned til nær ved den nedre ende av betonglegemet. Oventil blir opphopningen av armeringsjern derfor stor, så at denne blir særlig motstandsdyktig for støtpåkj ennin-ger. For å sentrere og fastspenne masten 3 også til fundamentets øvre ende er der i spalten mellom masten og skoen innført et sentreringsorgan, som i det viste eksem-pel utgjøres av en på utsiden svakt konisk hylse 8, som er oppslisset etter lengden. Ved monteringen av masten kan denne hylse liksom en hetteformet beskyttende ring 9 anbringes på masten, før dennes en-de føres inn i hullet 2. Etter at masten er kommet i stilling inndrives den koniske hylse med et pasende verktøy, hvorpå ringen 9 føres til den på tegningen viste stilling, hvori den dekker sentreringsanord-ningen. I ringen 9 er hensiktsmessig an-ordnet en mot masten under trykk anlig-gende tetningspakning 10. At the upper part of the hole 2, a metallic reinforcing ring or sleeve-shaped shoe 6 is cast in the concrete, which is welded together with longitudinal reinforcing bars 7, so that a construction that is very resistant to mechanical stress is obtained. Only part of the reinforcements, e.g. approximately half, need to extend down to close to the lower end of the concrete body. Above, the accumulation of rebar therefore becomes large, so that it becomes particularly resistant to shock loads. In order to center and fasten the mast 3 also to the upper end of the foundation, a centering device is introduced in the gap between the mast and the shoe, which in the example shown consists of a slightly conical sleeve 8 on the outside, which is slit along its length. When assembling the mast, this sleeve, like a cap-shaped protective ring 9, can be placed on the mast, before its end is inserted into the hole 2. After the mast is in position, the conical sleeve is driven in with a suitable tool, after which the ring 9 is inserted into the position shown in the drawing, in which it covers the centering device. In the ring 9, a sealing gasket 10 is suitably arranged against the mast under pressure.
Som det fremgår også av fig. 2, er skoen 6 oppad konisk utvidet dels for at klemhylsen 8 lett skal kunne styres inn i skoen og dels foråt klemhylsen skal kom-me til anlegg mot et parti 6a av skoen som ligger et stykke nedenfor fundamentets overkant. Om masten 3 blir utsatt for et kraftig støt, f. eks. av en påkjørende bil, vil støtet overføres til fundamentet ved delen 6a, hvor betongen er kraftig for-sterket av armeringen. Delen 6a kan ha et indre vinkelmål a av omtrent 95° mot ho-rinsontalplanet. Det øvre parti av delen 6 har større indre vinkelmål. As can also be seen from fig. 2, the shoe 6 is conically extended upwards partly so that the clamping sleeve 8 can be easily guided into the shoe and partly before the clamping sleeve is to come into contact with a part 6a of the shoe which lies a little below the upper edge of the foundation. If the mast 3 is exposed to a strong shock, e.g. of an oncoming car, the impact will be transferred to the foundation at section 6a, where the concrete is heavily reinforced by the reinforcement. The part 6a can have an internal angle measure a of approximately 95° to the horizontal plane. The upper part of the part 6 has larger internal angular measurements.
Fundamentet har hensiktsmessig en oppad avsmalnende øvre del 11 og det er således nedsenket i jorden, at jordflaten 12 ligger ved dette konisk avsmalnende parti, så at bare en liten del av fundamentet stik-ker opp over jorden. Nedentil har fundamentet hensiktsmessig en utvidet del 13 for å forbedre forankringen i jorden og særlig for å skaffe stor motstand mot opp-trekning av fundamentet fra jorden. Om en mast skal føres opp fra fundamentet kan dette nemlig skje således, at masten trekkes oppad ved hjelp av en passende løfteinnretning. Hvis forbindelsen 8 sitter meget hårdt fast, kreves en stor løftekraft på masten for å løsne forbindelsen. The foundation suitably has an upwardly tapering upper part 11 and it is thus sunk into the ground, that the ground surface 12 lies at this conically tapering part, so that only a small part of the foundation protrudes above the ground. Beneath, the foundation appropriately has an extended part 13 to improve the anchoring in the earth and in particular to provide great resistance to the foundation being pulled up from the earth. If a mast is to be raised from the foundation, this can be done in such a way that the mast is pulled upwards using a suitable lifting device. If the connection 8 is very tight, a large lifting force is required on the mast to loosen the connection.
Oppfinnelsen er ikke begrenset ,til den på tegningen viste utførelsesform. Således kan den koniske hylse 8 erstattes med at-skilte kiler, som drives ned i spalten. Eventuelt kan den istedet erstattes med en ring av elastisk materiale, f. eks. gummi, som under formforandring drives hårdt ned i spalten og da samtidig virker tettende. Armeringsj ernene kan være forbundet med en særskilt forsterkningsring, som ligger helt innstøpt i betongen. The invention is not limited to the embodiment shown in the drawing. Thus, the conical sleeve 8 can be replaced with spaced wedges, which are driven down into the slot. Alternatively, it can instead be replaced with a ring of elastic material, e.g. rubber, which during the change of shape is driven hard into the gap and then at the same time has a sealing effect. The rebars can be connected with a special reinforcing ring, which is completely embedded in the concrete.
Den øvre flate på fundamentet er hensiktsmessig svakt hellende utad. The upper surface of the foundation is suitably slightly sloping outwards.
