Description

Pelebeskytter mot is. Pile protector against ice.

Oppfinnelsen angår en beskyttelsesanordning for peler med det gene-relle formål å hindre at pelene løftes opp på grunn av bevegelser i omgivende is. The invention relates to a protection device for piles with the general purpose of preventing the piles from being lifted up due to movements in the surrounding ice.

Det er tidligere kjent å forsøke å beskytte peler mot isgang. Den mest anvendte metode er å fjerne pelene før sjøen fryser til. Dette er både tungvint, vanskelig og kostbart. It is previously known to try to protect piles against ice. The most used method is to remove the piles before the lake freezes over. This is cumbersome, difficult and expensive.

En annen metode består i å kle inn pelene med et stoff som isen ikke fryser fast til eller å smøre pelene utenpå i samme hensikt. Ingen Another method consists of covering the piles with a material to which the ice does not freeze or to lubricate the outside of the piles for the same purpose. No

av disse metoder oppfyller hensikten i det lange løp. of these methods fulfills the purpose in the long run.

Fra USA patent nr. 3.180.099 er cLet kjent å anbringe en ytre foring utenpå støpte sementpeler. De patenterbare komponentene består av en ytre foring hvortil er festet et plastbelegg som ligger an mot pelen. Mellom toppen av foringen og underkant av bryggen er det anbragt en spiralf jaer som presser foringen ned til utgangsstillingen igjen etterat isens løftevirkning er opphørt. Oppfinnelsen har den mangel at anordningen kun kan benyttes til støpte pilarer av sirkulært tverrsnitt med den samme diameteren i løftehøyden. Videre må foring med plastbelegg, spiralfjæren m.v. anbringes på pilaren før bryggen legges på - plass. Plastbelegget kan ikke fornyes før en omgivende kappe og diverse andre deler er fjernet. Anordningen kan forøvrig neppe benyttes til pilarer for brygger som ligger forholdsvis lavt over vannet. Nærværende konstruksjon oppviser ingen av de nevnte manglene. From US patent no. 3,180,099 it is known to place an outer lining on the outside of cast cement piles. The patentable components consist of an outer lining to which is attached a plastic coating that rests against the pile. Between the top of the liner and the bottom edge of the jetty, a spiral spring is placed which pushes the liner down to the starting position again after the lifting effect of the ice has ceased. The invention has the disadvantage that the device can only be used for cast pillars of circular cross-section with the same diameter in the lifting height. Furthermore, lining with plastic coating, the coil spring etc. placed on the pillar before the pier is put into place. The plastic coating cannot be renewed until a surrounding sheath and various other parts have been removed. Incidentally, the device can hardly be used for pillars for jetties that are relatively low above the water. The present construction exhibits none of the aforementioned shortcomings.

OppfinneIsens særegne formål består i å benytte komponenter utenpå pelene som beveger seg opp og ned sammen med isen uten å påvirke pelene i vertikal retning. InventingIsen's distinctive purpose is to use components on the outside of the piles that move up and down with the ice without affecting the piles in a vertical direction.

Denne oppgave er løst ved å omgi peler av alle slag og uansett om disse har den samme diameteren langsetter, med påskrudde, todelte metallforinger av samme diameter hele veien og anbringe todelte beholdere utenpå disse. Beholderene, som skrues sammen med hjelp av vertikaltstående flenser, fylles opp med grease eller et annet paS- This task is solved by surrounding piles of all kinds, regardless of whether these have the same diameter, with screwed-on, two-part metal linings of the same diameter all the way around and placing two-part containers on top of them. The containers, which are screwed together with the help of vertical flanges, are filled with grease or another paS-

An embodiment of the invention is shown in fig. 1 which shows the device seen in section from the side and from above.

Bn two-part metal liner 1 is fixed with countersunk screws 2 to a pole 3« The metal liner has the same diameter throughout its length. Around this liner, a two-part container 4 is fitted with a sliding fit, which is screwed together using the flanges 5 and the screws 6. The container, which abuts the liner only at the top and bottom, has a larger diameter than the liner, so that a cavity 7" I is formed a hole 8 has been drilled in the top which can be closed by screwing in a plug. Grease with added antifreeze is filled through the hole. Lining and container are placed on the pile at the height that the surrounding water usually has when it freezes.

The device works in the following way x When the ice around the pile freezes, it sticks to the outer container. If the ice were to raise or lower, it would only raise or lower the container. The lubricant and freezing agent in the container, which abuts the liner, will cause the vertical forces not to be transferred to the pile.

Patent requirement 1. Device for protecting pillars and piles against the effects of ice, characterized in that two-part metal linings are screwed on around these at the height of the water level, and that two-part containers containing a freeze-proof lubricant are placed around them with a sliding fit that rests against the outside of the metal lining.

2. Device as specified in claim 1, characterized in that the two-part metal liners have the same diameter throughout their length, regardless of whether the pillars or piles do not have the same diameter throughout the length of the metal liners.
