Description
Ekspansjonsfeste. Expansion bracket.
Oppfinnelsen angår et ekspansjonsfeste, beregnet til å anbringes i et borhull i fjell, betong etc. og bestående av en i borhullet innførbar hylse, med et i hylsens indre ende anbragt organ som ved hjelp av en fra hylsens ytre ende innførbar dor e. 1. presses utad for utvidelse av den indre hylseende og tilpressning mot borhull-veggen. The invention relates to an expansion attachment, intended to be placed in a drill hole in rock, concrete etc. and consisting of a sleeve that can be inserted into the drill hole, with an organ located at the inner end of the sleeve which, by means of a mandrel that can be inserted from the outer end of the sleeve, e. 1. is pressed outwards to expand the inner sleeve end and press against the borehole wall.
Det særegne ved anordningen etter oppfinnelsen er at det utpressbare organ dannes av et antall i hylsens indre ende innførte og med hylsens akse parallelle staver, som ligger an mot hylsens innside. Etter en hensiktsmessig utførelsesform inneslutter nevnte staver et mellomrom, hvori doren etc, som er utformet med en konisk spiss, trenger inn. Nevnte mellomrom mellom stavene kan oppnås ved at stavene er av rundt tverrsnitt, idet det da fremkommer mellomrom for inntrengning av doren. The peculiarity of the device according to the invention is that the extrudable body is formed by a number of rods inserted in the inner end of the sleeve and parallel to the axis of the sleeve, which rest against the inside of the sleeve. According to an appropriate embodiment, said rods enclose a space, into which the mandrel etc., which is designed with a conical tip, penetrates. Said spaces between the rods can be achieved by the rods having a round cross-section, as spaces are then created for penetration of the mandrel.
Fordelene ved anordningen er at ekspansjonsfestet blir billig i fabrikasjon, idet det helt enkelt kan brukes rør som er avkappet i passe lengder og disse behøver ikke være nye, men kan godt være vrakrør. Stavene kan bestå av rundtjern, firkant-jern eller av flate jern eller ha annet pro-fil, da det ikke fordres en nøyaktig tilpas-sing. Ekspansjonsfestet kan takket være røret, oppta betydelige trekkrefter og andre påkjenninger. Man velger rørets dimensjon etter de opptredende påkjenninger. På grunn av den kraftige utvidelse ved rørets indre ende, ved dorens inndrivning, er det ingen risiko for at festet skal løsne eller dras ut. Rørenden sammen med stavene og doren danner nemlig praktisk talt en mas-siv del. Ved at man bruker et rør, blir det mulig å skyte festet fast med en boltpistol, hvorunder røret danner styring for pistol-pipen. Doren dannes altså i dette tilfelle av et projektil 10. The advantages of the device are that the expansion bracket is cheap to manufacture, as pipes that have been cut to suitable lengths can simply be used and these need not be new, but may well be scrap pipes. The rods can consist of round irons, square irons or flat irons or have a different profile, as an exact fit is not required. Thanks to the pipe, the expansion bracket can take up significant tensile forces and other stresses. The pipe's dimension is chosen according to the stresses that occur. Due to the strong expansion at the inner end of the tube, when the mandrel is driven in, there is no risk of the fastener loosening or being pulled out. The tube end together with the rods and the mandrel practically form a solid part. By using a tube, it becomes possible to shoot the mount firmly with a bolt gun, under which the tube forms a guide for the gun barrel. The mandrel is thus formed in this case by a projectile 10.
I det følgende blir oppfinnelsen for-klart under henvisning til tegningen, hvor fig. 1 viser et lengdesnitt gjennom et i et borhull i taket i et rom i fjellet innført ekspansjonsfeste. Fig. 2 viser et liknende snitt med ekspansjonsf estet fastgjort. Fig. In the following, the invention is explained with reference to the drawing, where fig. 1 shows a longitudinal section through an expansion attachment inserted in a drill hole in the ceiling of a room in the mountain. Fig. 2 shows a similar section with the expansion bracket attached. Fig.
3 viser et tverrsnitt etter linjen III—III i 3 shows a cross-section along the line III—III i
fig. 1. fig. 1.
I eksemplet tenkes ekspansjonsfestet brukt til å fastholde et pussenett 1, anbragt under taket. I taket er uttatt et antall boringer 2 og i hvert av disse innføres et ekspansjonsfeste. In the example, the expansion attachment is thought to be used to hold a plaster net 1, placed under the roof. A number of holes 2 have been taken in the ceiling and an expansion attachment is introduced in each of these.
Ekspansjonsfestet består av en hylse 3 hvis ytterdiameter bare er ubetydelig min-dre (f. eks. ca. 1—2 mm) enn borhullets 2 diameter. Ved den ytre ende av hylsen 3 er denne forsynt med et tverrstykke 4, som i eksemplet består av en til hylsens ytre ende fastsveiset, tverrsgående rund stav, som tjener til å fastholde pussenettet 1 mot eller nær taket 5. Ved den indre ende av hylsen 3, hvis lengde er noe større enn boringen 2, er det ført inn et antall runde staver 6, 7, som ligger parallelt med hylse-aksen og ligger an mot hylsens innside, og mellom seg danner hulrom 8 ved hylsens akselinje. Stavene 6, 7 fastholdes i hylseenden bare ved hjelp av friksjonen mellom stavene og hylsen. The expansion attachment consists of a sleeve 3 whose outer diameter is only slightly smaller (e.g. approx. 1-2 mm) than the diameter of the drill hole 2. At the outer end of the sleeve 3, this is provided with a cross piece 4, which in the example consists of a transverse round rod welded to the outer end of the sleeve, which serves to hold the plaster net 1 against or close to the ceiling 5. At the inner end of the sleeve 3, the length of which is somewhat greater than the bore 2, a number of round rods 6, 7 are inserted, which lie parallel to the sleeve axis and abut against the inside of the sleeve, and between them form a cavity 8 at the axis line of the sleeve. The rods 6, 7 are held in the sleeve end only by means of the friction between the rods and the sleeve.
Etter at hylsen 3 er innført i borhullet til den i fig. 1 viste stilling, innføres gjennom hylsens ytre ende et forlengelsesstykke 9 til en boltpistols (ikke vist) pipe, hvor-etter et prosjektil 10 skytes inn i hulrom-met 8 og presser stavene 6, 7 ut fra hinannen, slik at det indre endeparti 11 av ekspansjonshylsen 3 utvides og presses mot veggen i borhullet 2 (fig. 2). After the sleeve 3 has been introduced into the drill hole of the one in fig. 1 position, an extension piece 9 is inserted through the sleeve's outer end to the barrel of a bolt gun (not shown), after which a projectile 10 is shot into the cavity 8 and pushes the rods 6, 7 out from each other, so that the inner end part 11 of the expansion sleeve 3 is expanded and pressed against the wall of the borehole 2 (fig. 2).
Derved fastslåes ekspansjonsfestet ef-fektivt i hullet, samtidig som pussenettet I fastholdes i sin stilling. Det bemerkes at nettet 1, hylsen 3 og boltpistolen kan holdes av en enkelt mann og manøvreres av ham. Tilslutt anbringes så et puss-lag 12 på kjent måte, så både pussnettet 1 og hylsens 3 ytre ende med tverrstykket 4 inn-kapsles i pusslaget 12. Thereby, the expansion attachment is effectively established in the hole, while the plaster mesh I is maintained in its position. It is noted that the net 1, the sleeve 3 and the bolt gun can be held by a single man and maneuvered by him. Finally, a plaster layer 12 is then placed in a known manner, so that both the plaster net 1 and the outer end of the sleeve 3 with the cross piece 4 are encapsulated in the plaster layer 12.
Den viste og beskrevne utførelsesform er bare å betrakte som et eksempel og ekspansjonsf estets forskjellige deler kan kon-struktivt endres på mange måter innenfor oppfinnelsens ramme. The shown and described embodiment is only to be considered as an example and the various parts of the expansion bracket can be constructively changed in many ways within the framework of the invention.
I stedet for runde staver 6, 7 kan så-ledes brukes staver av annet tverrsnitt. Hensiktsmessig er antallet av staver minst tre og anbringes slik at det dannes et hulrom 8 mellom dem. Instead of round rods 6, 7, rods of a different cross-section can therefore be used. Conveniently, the number of rods is at least three and is placed so that a cavity 8 is formed between them.
I stedet for å skyte et prosjektil 10 inn mellom stavene 6, 7 kan man fra hylsens 8 ytre ende slå inn en i den indre ende konisk avspisset dor, som presser stavene 6, 7 fra hinannen og tvinger hylsens endeparti II til å utvide seg, så det presses mot borhullets vegg. Forøvrig kan nevnes at hvis man bruker boltpistol og et spisst prosjektil av stål, så kan ekspansjonsorganet 6, 7 i hylsens indre ende dannes av et massivt legeme, eksempelvis et vesentlig sylindrisk stykke mykt jern, som når prosjektilet skytes inn slites i alle fall delvis i stykker, og derved tvinger hylsepartiet 11 til å utvide seg. Hylsens 3 ytre ende kan i stedet for et tverrstykke 4, være forsynt med utvendige og innvendige skruegj enger og til disse passende bolter, resp. muttere eller andre festemidler. Tilslutt kan nevnes at ekspansjonsfestet naturligvis kan brukes til anbrin-gelse i annet fast materiale enn fjell, og til feste av andre ting enn et pussenett. Instead of shooting a projectile 10 between the rods 6, 7, a mandrel tapered at the inner end can be driven in from the outer end of the sleeve 8, which pushes the rods 6, 7 away from each other and forces the end part II of the sleeve to expand, so it is pressed against the borehole wall. Incidentally, it can be mentioned that if a bolt gun and a pointed projectile made of steel are used, then the expansion member 6, 7 at the inner end of the sleeve can be formed by a massive body, for example a substantially cylindrical piece of soft iron, which when the projectile is fired wears at least partially in pieces, thereby forcing the sleeve portion 11 to expand. The outer end of the sleeve 3 can, instead of a cross piece 4, be provided with external and internal screw threads and suitable bolts for these, resp. nuts or other fasteners. Finally, it can be mentioned that the expansion bracket can of course be used for installation in solid material other than rock, and for fixing things other than a plaster net.
