Abstract

The invention relates to a device for securing poles in foundations. As shown in Fig. 1c, one embodiment relates to stays 2 which are fixed partly in the shell 3 of the pole and partly in its flange 1. Fig. 1a shows the extra deflection 4 with which the stays are provided, one or more of which stays are straightened out, under the absorption of energy absorption, when the shell of the pole is demolished upon being knocked down by a vehicle. The invention is especially advantageous in respect of pliable road poles made of thin plate, which are commonly cut in two when knocked down by a vehicle but in which the stays, as they straighten out, secure both the pole and the vehicle. <IMAGE>

Description

15 20 25 '7906646-0 Stagen tjänstgör som förankringsdon mellan markfäste och avdragen stolpe och resultatet blir att såväl stolpe som påkörande fordon fångas upp. 15 20 25 '7906646-0 The struts serve as anchoring devices between the ground bracket and the towed post and the result is that both the post and the oncoming vehicle are caught.

En variant av energiupptagande stag kan erhållas med bandplåt som är perforerad på ett särskilt sätt. Ett hålmönster göres så, att bandplåten slites av i vissa partier av sin bredd men ej helt, utan ett obrutet materialtvärsnitt kvarhåller stolpen vid markfästet. Denna effekt ernås genom att exempelvis hålrader göres i tvärled i bandplåten och att växel- vis sísta hålet eller hålen i varje rad utelämnas, varvid materialet blir obrutet där. Avståndet mellan hålkanterna är förhållandevis litet och vid påkänning brister plåten där. En sicksackformad brottbild uppstår. Genom att anpassa materialanhopningen kan man på detta sätt erhålla kraft- dämpande stag. I stället för hålrader kan slitsar stansas. Vidare kan bandplåten utvidgas på bredden till ett rörformigt stag utefter hela in- sidan av stolpen.A variant of energy-absorbing struts can be obtained with strip plate which is perforated in a special way. A hole pattern is made so that the strip plate wears off in certain parts of its width but not completely, but an unbroken material cross-section retains the post at the ground attachment. This effect is achieved by, for example, making rows of holes transversely in the strip plate and alternately omitting the last hole or holes in each row, whereby the material remains unbroken there. The distance between the hole edges is relatively small and during stress the plate breaks there. A zigzag-shaped crime scene occurs. By adapting the material accumulation, you can obtain force-absorbing struts in this way. Instead of rows of holes, slots can be punched. Furthermore, the strip plate can be extended in width to a tubular stay along the entire inside of the post.

Fig. 1 - 5 visar fästen för anslutning mellan en fläns 1 och stolpens underdel 3.Figs. 1 - 5 show the brackets for connection between a flange 1 and the lower part 3 of the post.

Fig. 6 - 9 visar fästen för anslutning av en stolpe nedstucken i ett fundament.Figs. 6 - 9 show the brackets for connecting a post inserted into a foundation.

Fíg. 10 visar staganordning med perforerad bandplåt.Fig. 10 shows strut device with perforated strip plate.

Fíg. 11 visar ett utdraget stag enligt fig. 10.Fig. Fig. 11 shows an elongated strut according to Fig. 10.

Fig. 1 visar stag tillverkade av plattjärn och svetsade i sin övre del till stolpens insida och sin nedre del svetsade till flänsens undersida.Fig. 1 shows struts made of flat iron and welded in its upper part to the inside of the post and its lower part welded to the underside of the flange.

Mellan dessa punkter är staget bockat i en särskild krök 4 i enlighet med uppfinningstanken. Fig. 1a visar ett enskilt stag, fig. 1b visar ett stag monterat på fläns 1 och fig. 1c visar sex stag monterade i en stolpe.Between these points the strut is bent in a special bend 4 in accordance with the inventive concept. Fig. 1a shows a single strut, Fig. 1b shows a strut mounted on flange 1 and Fig. 1c shows six struts mounted in a post.

Fig. 2 - 4 visar varianter av utformning av stag i form av rundjärn som är fästade i dels mantelytan på insidan och dels i särskilda hål i flänsen. 10 15 20 7906646-0 Fig. 5 visar en variant som består av ett förhållandevis tunt rör 5 som är hoptryckt som en bälg 6 i axiell riktning. Det är därefter fästat dels på mantelytans insida, dels i flänsen. Dess kraftdämpande förmåga utgöres av utdragning av röret i axialled.Figs. 2 - 4 show variants of the design of struts in the form of round irons which are attached partly to the mantle surface on the inside and partly to special holes in the flange. Fig. 5 shows a variant consisting of a relatively thin tube 5 which is compressed like a bellows 6 in the axial direction. It is then attached partly to the inside of the mantle surface and partly to the flange. Its force-damping ability consists of pulling out the pipe in the axial direction.

Fig. 6 visar samma stagtyp som i Fig. 1.. stolpen lir emellertid icke Fläns- Eörsedd utan avsedd att nedstickas i fundament. Stagen är därför Fästade i dels ett parti 3 över markytan på stolpens insida, dels ett parti 7 under markytan och mellan dessa partier krökt i en eller flera böjar.Fig. 6 shows the same strut type as in Fig. 1 .. However, the post is not flanged and intended to be inserted into the foundation. The struts are therefore attached in a part 3 above the ground surface on the inside of the post, and a part 7 below the ground surface and between these parts curved in one or more bends.

Fíg. 7 - 8 visar motsvarande utförande som fig. 6 ehuru med runda stag.Fig. 7-8 show the corresponding embodiment as Fig. 6, although with round struts.

Fíg. 9 visar samma utförande som fig. 5 ehuru med hoptryckt slítsat rör fästat i dels ett parti över markytan, dels ett parti under markytan.Fig. Fig. 9 shows the same embodiment as Fig. 5, although with compressed slotted pipe attached in partly a portion above the ground surface and partly a portion below the ground surface.

Fig. 10 visar en staganordning med bandplåt 10 och hålrader 11 som har växelvis sista hålet utelämnat varför en materíalanhopning 12 sker där.Fig. 10 shows a stay device with strip plate 10 and rows of holes 11 which have alternately left the last hole omitted, which is why an accumulation of material 12 takes place there.

Hålraderna kan ersättas med slitsar.The rows of holes can be replaced with slots.

Fig. 11 visar ett stag som dragits ut vid exempelvis en krock. Materialet 13 mellan hålraderna har brustit utom på det ställe 12 där det förekommit mera obrutet. Bandplåten har dragits ut och utgör en kraftminskande för- ankring mellan markfäste 1 och stolpens mantelyta.Fig. 11 shows a strut which has been pulled out in the event of, for example, a collision. The material 13 between the rows of holes has broken except at the place 12 where it has been more unbroken. The strip plate has been pulled out and forms a force-reducing anchorage between ground bracket 1 and the mantle surface of the post.

Här visade utföranden är ingalunda de enda som uppfyller uppfinningstanken.The embodiments shown here are by no means the only ones that meet the inventive concept.

Varianter kan göras, exempelvis kan stagen förläggas på mantelytans utsida, de kan fästas genom skruvförband så att en kraftdämpande effekt ernås genom friktion eller de kan förses med någon typ av fjädrar som är dimvnsionerade för ändamålet.Variants can be made, for example the struts can be placed on the outside of the mantle surface, they can be fastened by screw joints so that a force-damping effect is achieved by friction or they can be provided with some type of springs which are dimensioned for the purpose.
