Description

Anordning ved prøvepropper for sementrør og lignende. Device for test plugs for cement pipes and the like.

Når tettheten av et f. eks. nylaget se-mentrør skal prøves går man i alminnelig-het frem på den måte, at en propp i opp-rettstående stilling av røret innsettes i dettes oppadvendende ende. Deretter en-devendes røret, så at proppen blir liggen-de an mot underlaget, hvoretter røret til-føres vann gjennom den nu oppadvendende åpne ende. Man anvender herved van-ligvis en propp, bestående i hovedsaken av en gummiring eller lignende, som er anbragt mellom to plater, av hvilke den ene er fortrinnsvis fast forbundet med en cen-tralt anordnet, gjennom gummiringen og en åpning i den annen plate gående bolt, på hvis frie ende kan påskrues en mutter, som ved tilskruing mot den sistnevnte plate tvinger platene i retning mot hverandre, så at gummiringen utpresses til tettende anlegg mot rørets innervegg. When the density of an e.g. newly made cement pipe is to be tested, one generally proceeds in such a way that a plug in an upright position of the pipe is inserted into its upward-facing end. The pipe is then turned, so that the stopper lies against the substrate, after which water is added to the pipe through the open end, which now faces upwards. A stopper is usually used here, consisting mainly of a rubber ring or the like, which is placed between two plates, one of which is preferably firmly connected to a centrally arranged, passing through the rubber ring and an opening in the other plate bolt, on the free end of which a nut can be screwed on, which, when screwed against the last-mentioned plate, forces the plates in the direction of each other, so that the rubber ring is pressed into a tight fit against the inner wall of the pipe.

En ulempe ved anvendelse av slike A disadvantage of using such

propper er imidlertid, dels at proppen er tilbøyelig til å gli eller falle ned i røret, når proppen skal festes inne i rørets ut-advendende ende, dels at boltens frie ende eller mutteren, når røret er bragt til å stå på sin med proppen forsynte ende, ligger an mot underlaget og derved forårsaker, at røret står skrått eller usikkert på underlaget. plugs, however, is partly that the plug is inclined to slide or fall into the pipe, when the plug is to be fixed inside the outward-facing end of the pipe, partly that the free end of the bolt or the nut, when the pipe is brought to stand on its end provided with the plug end, rests against the substrate and thereby causes the pipe to stand obliquely or precariously on the substrate.

Formålet med oppfinnelsen er å til-veiebringe en anordning ved nevnte type av propper, som muliggjør, at et rør, lukket med en propp, som er forsynt med anordningen ifølge oppfinnelsen, må kunne stå stabilt på et plant underlag med den lukkede ende vendende nedover, og som på en sikker måte hindrer proppen i å falle inn i rørenden ved proppens befestigelse. The purpose of the invention is to provide a device with said type of stopper, which makes it possible for a pipe, closed with a stopper, which is provided with the device according to the invention, to be able to stand stably on a level surface with the closed end facing downwards , and which reliably prevents the stopper from falling into the pipe end when the stopper is attached.

Anordningen ifølge oppfinnelsen ka-rakteriseres i hovedsaken ved at den av mutteren påvirkbare plate på den mot mutteren vendende side har ett eller flere bæreorganer, som er anordnet til å ligge an mot en ende av røret på en sådan måte, at når proppen skal anbringes i rørenden og denne er vendt oppover, så forhindrer bæreorganene proppen i å gli ned gjennom røret under gummiringens utpresning, og når rørenden etter gummiringens utpresning vendes nedover holder bæreorganene proppen opp fra underlaget, så at bolten med mutteren holdes oppløftet og røret inntar stabil stilling. The device according to the invention is mainly characterized by the fact that the plate that can be influenced by the nut on the side facing the nut has one or more support members, which are arranged to rest against one end of the pipe in such a way that when the plug is to be placed in the pipe end and this is turned upwards, then the support means prevent the plug from sliding down through the pipe during the rubber ring's extrusion, and when the pipe end is turned downwards after the rubber ring has been squeezed out, the support members hold the plug up from the ground, so that the bolt with the nut is kept lifted and the pipe assumes a stable position.

Ifølge oppfinnelsen består bæreorganene av minst to på hver sin side av åpningen i platen for bolten på kant stilte bjelker eller av et antall knaster eller av en ring, hvilke organer raker ut fra platen på en sådan måte, at de når proppen er anbragt i røret ligger an mot rørets ende. According to the invention, the support members consist of at least two on either side of the opening in the plate for the bolt on edge or of a number of knobs or of a ring, which members protrude from the plate in such a way that when the stopper is placed in the pipe lies against the end of the pipe.

En utførelsesform av oppfinnelsen er anskueliggjort som eksempel på hosstående tegning. Fig. 1 viser i perspektiv et på et underlag på ende stående sementrør, hvis oppadvendende ende er lukket med en propp, som er forsynt med anordningen ifølge oppfinnelsen. Fig. 2 viser samme rør endevendt, dvs. med den av proppen lukkede ende vendende mot underlaget. An embodiment of the invention is illustrated as an example in the accompanying drawing. Fig. 1 shows in perspective a cement pipe standing on end on a base, the upward-facing end of which is closed with a stopper, which is provided with the device according to the invention. Fig. 2 shows the same pipe end facing, i.e. with the end closed by the plug facing the substrate.

På tegningen er røret betegnet med 1, proppens plater med 2 og 3 og gummiringen med 4. Bolten er betegnet med 5, mutteren med 6 og underlaget med 7. In the drawing, the tube is designated by 1, the plug's plates by 2 and 3 and the rubber ring by 4. The bolt is designated by 5, the nut by 6 and the support by 7.

Ifølge oppfinnelsen er det til den av mutteren 6 påvirkbare plate 2 på den mot mutteren vendende side festet et antall According to the invention, on the side facing the nut, a number of
