Abstract
Description
1909691-3 2 sektionernas längsgående sidokanter en dämpfläns 7, som lämpligen bildar en vinkel OC mot vertikalplanet av ca 45°. 1909691-3 2 longitudinal side edges of the sections a damping flange 7, which suitably forms an angle OC towards the vertical plane of about 45 °.
Vid det visade utföringsexemplet är dämpflänsarna 7 gjutna i ett stycke med stommen 2 till ifrågavarande flytsektion. När flytsektionen är gjuten av betong kommer en stor del av sektionens massa att vara belägen förhållandevis långt från sektionens tyngdpunktcentrum. Genom att flänsarna 7 sträcker sig ned i de undre vattenskikten kommer flytsektionen att ' bli förhållandevis okänslig för vågrörelser i de övre vatten- skikten. Vidare är flänsarna 7 försedda med ett antal genomström- ningsöppningar 8, som vid det visade utförandet är belägna i närheten av övergången mellan dämpflänsarna 7 och flytkroppens stomme 2. Genomströmningsöppningarna 8 kommer vid vágrörelser i vattnet att förorsaka en turbulens, som stör vågrörelsen närmast bryggan och försämrar dess möjlighet att påverka bryggan. Vid det visade utföringsexemplet är dämpflänsarna 7 gjutna i ett stycke med flytsektionernas stomme, men det är naturligtvis också möjligt att inom uppfinningens ram utföra dessa som separata element, vilka är fast eller lösbart monterade på respektive bryggsektion. Vid det visade utföran- det är bryggsektionerna öppna vid sina ändar, men det är naturligtvis möjligt att förse dem med gavlar, som sträcker sig ända ned till dämpflänsarnas nedre kanter 7a. Vattenytan betecknas med 9 på ritningen.In the embodiment shown, the damping flanges 7 are cast in one piece with the body 2 of the floating section in question. When the floating section is cast of concrete, a large part of the mass of the section will be located relatively far from the center of gravity of the section. As the flanges 7 extend down into the lower water layers, the floating section will become relatively insensitive to wave motions in the upper water layers. Furthermore, the flanges 7 are provided with a number of flow openings 8, which in the embodiment shown are located in the vicinity of the transition between the damping flanges 7 and the float body 2. The flow openings 8 will cause a turbulence during wave movements in the water which disturbs the wave movement closest to the bridge and impairs its ability to affect the bridge. In the embodiment shown, the damping flanges 7 are cast in one piece with the body of the floating sections, but it is of course also possible to design these within the scope of the invention as separate elements, which are fixedly or releasably mounted on the respective bridge section. In the embodiment shown, the bridge sections are open at their ends, but it is of course possible to provide them with ends, which extend all the way down to the lower edges 7a of the damping flanges. The water surface is denoted by 9 in the drawing.
Uppfinningen är ej begränsad till det endast såsom exempel ovan beskrivna och på ritningen visade utförandet, utan kan varieras till sina detaljer inom ramen för efterföljande patentkrav utan att uppfinningens grundtanke därmed frångås.The invention is not limited to the embodiment described only as an example above and shown in the drawing, but can be varied in its details within the scope of the appended claims without departing from the basic idea of the invention.
Således kan dämpflänsarna enligt uppfinningen tillämpas även vid andra typer av flytbryggor än bryggor av det slag, som visas på ritningen. Om flytbryggor av konventionellt slag med flytpontoner förses med dämpflänsar enligt uppfinningen, kommer även i detta fall en mycket gynnsam vågbrytande effekt att uppnås med dessa.Thus, the damping flanges according to the invention can also be applied to other types of floating bridges than bridges of the type shown in the drawing. If floating bridges of a conventional type with floating pontoons are provided with damping flanges according to the invention, a very favorable wave-breaking effect will also be achieved with them in this case.
