Description

Krossing-spiss. Crushing tip.

Den krossing-spiss av stopestål som er gjenstanden for sokeréns franske patent 1.145.811, utmerker seg ved at den er kasseformet med hovedsakelig rektangulært tverrsnitt inndelt ved tverrgående skillevegger i suksessive celleformer som hver er gjennombrutt i sin bunn av en nedre åpning og omfatter dessuten komplementære delskillevegger for forsterkning. The stop steel crossing point which is the subject of Soker's French patent 1,145,811 is distinguished by being box-shaped with a substantially rectangular cross-section divided by transverse partitions into successive cell shapes each pierced at its base by a lower opening and also comprising complementary partial partitions for reinforcement.

Denne krossing-spiss har vist seg meget tilfreds-stillende ved bruk. This crossing tip has proven very satisfactory in use.

Allikevel, for å oke dens stabilitet såvel som dens fasthet mot horisontale sprekkdannelser under driften i sonene for spissen, og tillate passeringen av skinnegående kjoretoyer med storre hastighet, går foreliggende oppfinnelse ut på en krossing-spiss av den nevnte type, som utmerker seg ved at den i sitt sentrale parti på hver side av enden av krysningspunktet har en utvidet sone, hvis celleformer dessuten har en nedre åpning som er mindre enn de andre celleformer i krossingspissen og som på hver side i hver celleform lar dét stå igjen sideområder av bunnen som strekker seg henholdsvis under de to rullebaner og tjener til stBtte for to komplementære skillevegger utformet som forsterkningsbuer for disse rullebaner. Nevertheless, in order to increase its stability as well as its firmness against horizontal cracking during operation in the zones in front of the tip, and to allow the passage of rail-running vehicles at greater speed, the present invention is based on a crossing tip of the aforementioned type, which is characterized by it in its central part on each side of the end of the crossing point has an extended zone, whose cell forms also have a lower opening that is smaller than the other cell forms at the crossing tip and which on each side of each cell form leaves lateral areas of the bottom extending themselves respectively under the two runways and serve to support two complementary partitions designed as reinforcement arches for these runways.

Denne krossing-spiss kan likeledes mellom sine to siste tverrgående ribber nærmest enden av krysningspunktet og foran endene av de to rullebaner omfatte ribber som er anbrakt parvis i 8amme tverrgående plan og som forbinder hver av krossing-spissens sideflater med den ytre kant av et av de to spor som omgir punket, hvori hjulflensene på de skinnegående kjoretoy som går over denne krossing-spiss, passerer. This crossing tip can likewise between its two last transverse ribs nearest the end of the crossing point and in front of the ends of the two runways comprise ribs which are placed in pairs in the same transverse plane and which connect each of the lateral surfaces of the crossing tip with the outer edge of one of the two tracks surrounding the point, in which the wheel flanges of the rail-running vehicles passing over this crossing tip pass.

Oppfinnelsen skal beskrives nærmere i det fBlgende under henvisning til tegningene, hvor fig. 1 er et planriss, fig. 2 er et lengdesnitt etter linjen II—II på fig. 1, fig. 3 er et oppriss sett fra den ene ende, fig. 4 til 13 er snitt henholdsvis etter linjene'IV-IV til XIII-XIII på fig. 1, og fig. 14 er et oppriss sett fra den annen ende. The invention will be described in more detail below with reference to the drawings, where fig. 1 is a plan view, fig. 2 is a longitudinal section along the line II—II in fig. 1, fig. 3 is an elevation view from one end, fig. 4 to 13 are sections respectively along the lines IV-IV to XIII-XIII in fig. 1, and fig. 14 is an elevation view from the other end.

Krossing-spissen 1 som er sv den type som er beskrevet i sBkerens eldre patent 1.145.811, har kasseform med hovedsakelig rektangulær tverrsnittsform som særlig vist pfi fig* 5 til 13. Dens bunn 2 er forsynt med et visst entall åpninger 3 for å tillate under-stBttelse av kjernen under stBpningen såvel som for uttaking av sanden* I dens sterkest påvirkede område på hver side av enden av krysningspunktet 4, forbinder langsgående ribber 5 med bueform de tverrgående ribber 6 innbyrdes og omgir åpningene 3. The crushing tip 1, which is of the type described in the applicant's earlier patent 1,145,811, is box-shaped with a substantially rectangular cross-sectional shape as particularly shown in Figs* 5 to 13. Its bottom 2 is provided with a certain number of openings 3 to allow support of the core during the pouring as well as for the removal of the sand* In its most strongly affected area on each side of the end of the crossing point 4, longitudinal ribs 5 arcuately connect the transverse ribs 6 to each other and surround the openings 3.

Hellom de to siste tverrgående ribber 6a og 6b under punktet 4 på krossing-spissen, men foran endene av rullebanene 7» er der blant annet anordnet, som vist på fig. 9 og 10, ribber 8 anbrakt parvis i samme tverrgående plan, som forbinder hver sideflate 9 av Around the last two transverse ribs 6a and 6b below the point 4 at the crossing tip, but in front of the ends of the runways 7", there are, among other things, arranged, as shown in fig. 9 and 10, ribs 8 placed in pairs in the same transverse plane, connecting each side surface 9 of

krossing-spissen med den ytre kant 10 av de to spor 11 som omgir punktet 4, bestemt for å muliggjBre passeringen av hjulflensene på the crossing tip with the outer edge 10 of the two grooves 11 surrounding the point 4, intended to enable the passage of the wheel flanges on

de skinnegående kjBretByer som går over krossing-spissen* the rail-running kjBretByer that goes over the crossing tip*

Man får således en forsterkning i den sterkest påvirkede sone av krossing-spissen mot endene av dane krysningspunkt 4 og de to rullebaner 7. You thus get a reinforcement in the most strongly affected zone of the crossing tip towards the ends of that crossing point 4 and the two runways 7.

Det vil forBvrig forstås at den ovenfor beskrevne og på tegningen vista utfflrelsesform av oppfinnelsen bare ex gitt som et rent eksempel og uten begrensning og at forskjellige modifikasjoner kan utfores uten å avvike fra oppfinnelsens ramme. It will also be understood that the embodiment of the invention described above and shown in the drawing is only given as a pure example and without limitation and that various modifications can be made without deviating from the scope of the invention.

Crushing-spisB made of steel with a box shape and mainly rectangular cross-section divided by transverse partitions into successive cell shapes, each of which is pierced at its bottom by a lower opening and also includes complementary partial partitions for reinforcement, characterized in that in its central part on each side of the end of the crossing point (4) has an extended zone, whose cell forms also have a lower opening (3) which is smaller than the other cell forms at the crossing tip and which on each side of each cell form leaves side perimeters of the bottom (2 ) which extend respectively under the two runways (7) and serve to support two complementary partitions designed as reinforcement arches for these runways.

2. Crossing tip according to claim 1, characterized in that in each of the first cell shapes in the central extended zone in front of the crossing point (4), the two complementary arc-shaped partitions extend parallel to two side surfaces (9, 9) at the tip, each of those with their ends rest against two transverse partitions (6,6) or (6,6b) which delimit this cell form, while at least in the last cell form (6b,6a) the two complementary partitions extend with an arc form (8, 8) across the tip side surfaces (9,9), where each of them with its two ends rests against the lower edges of the two side surfaces.
