Abstract
Øjeboltkobling til sammenkobling af betonflydebroer i længderetningen. Betonflydebroer er beton elementer på 2 - 5 m i bredden og 6 - 25 m i længden og 80 - 200 cm i højden elementerne har indstøbte polystyrenblokke til opdrift. Betonflydebroer anvendes som bådebroer i bl. Havne samt marinaer og de sammenkobles i længderetning for at nå den ønskede længde på et broeforløb. Det nye koblingsprincip som ønskes patenteret giver en meget enkelt design af betonflydebroer med helt rene flader uden komplicerede udsparinger og indstøbninger hvilket giver store besparelser i støbeprocessen, og en forenklet udlægning i havnebassinet. Koblingsbeslaget består af inserts (11) som vist på Fig. 5. og Fig. 6. i forbindelse med støbningen af elementerne skal der blot indstøbes 4 inserts (11) i hver ende af betonflydebroen. Når betonflydebroen gøres klar til udlægning i havnen skal der skrues 4 øjebolte (10) ind i inserts (11) til en præcis dybde i hver ende. Herefter kan brofagene bringes på plads og låses sammen med en dorn (12) der monteres i øjeboltene (10) og låser brofagene sammen i længderetningen. Opfindelsen er kendetegnet ved, at den giver stor stivhed/skivevirkning ved samlingen af 2 eller flere betonflydebroer, da en sidevejs belastning på en betonflydebro, fx bølge eller vægt, vil blive supporteret i afstivning og modstå vridning/krængning via alle øvrige sammenkoblede betonflydebroer, kendestegnet ved, at man nærmest får følelsen af at gå på fast grund. Opfindelsen er kendetegnet ved, at være meget enkelt, solid og billig i indkøb. Opfindelsen er kendetegnet ved, at systemet let, hurtig og billigt kan udskiftes i tilfælde af slidtage eller skader.Eye bolt coupling for connecting longitudinal concrete flow bridges. Concrete flow bridges are concrete elements 2 - 5 m in width and 6 - 25 m in length and 80 - 200 cm in height. The elements have built-in polystyrene blocks for buoyancy. Concrete flow bridges are used as boat bridges in eg. Ports as well as marinas and they are connected longitudinally to reach the desired length of a bridge course. The new coupling principle, which is desired to be patented, provides a very simple design of concrete flow bridges with perfectly clean surfaces without complicated recesses and moldings, which gives great savings in the casting process and simplified laying in the harbor basin. The coupling bracket consists of inserts (11) as shown in FIG. 5 and FIG. 6. For the casting of the elements, simply insert 4 inserts (11) at each end of the concrete flow bridge. When preparing the concrete floating bridge for laying in the harbor, screw 4 eyebolts (10) into inserts (11) to a precise depth at each end. Thereafter, the bridge phages can be brought into place and locked together with a mandrel (12) mounted in the eye bolts (10) and lock the bridge phages together in the longitudinal direction. The invention is characterized in that it provides high stiffness / slab effect in the assembly of 2 or more concrete flow bridges, since a lateral load on a concrete flow bridge, eg wave or weight, will be supported in stiffening and withstand twisting / tilting via all other interconnected concrete flow bridges. know that you almost get the feeling of going on solid ground. The invention is characterized by being very simple, solid and inexpensive in purchasing. The invention is characterized in that the system can be easily, quickly and cheaply replaced in the event of wear or damage.

Opfindelsen er en væsentlig forenkling af sammenkoblingen af to betonflydebroer i forhold til i dag kendte systemer, koblingssystemet er særdeles enkel, solid og billig i fremstilling.The invention is a substantial simplification of the interconnection of two concrete flow bridges in relation to today's known systems, the coupling system being extremely simple, solid and cheap in manufacture.
Opfindelsen kræver ikke brug af specielt værktøj, den kan hurtigt monteres af lægfolk og det er let- og billig at udskifte i tilfælde af slidtage eller skader.The invention does not require the use of special tools, it can be quickly mounted by lay people and it is easy and cheap to replace in case of wear or damage.
Opfindelsens forenkler støbningen af betonflydebroer i forhold til de i dag kendte metoder, hvorved der kan opnås store besparelser i forbindelse med en særdeles optimal/effektiv serieproduktion.The invention simplifies the casting of concrete flow bridges in relation to the methods known today, whereby great savings can be obtained in connection with a highly optimal / efficient series production.
Opfindelsen giver stor stivhed/skivevirkning ved samlingen af 2 eller flere elementer da en sidevejs belastning på et element, fx bølge eller vægt, vil blive supporteret i afstivning og modstå vridning via alle øvrige sammenkoblede betonflydebroer, kendestegnet ved, at man får følelsen af at gå på fast grund.The invention provides high stiffness / slab effect in the assembly of 2 or more elements since a lateral load on an element, eg wave or weight, will be supported in stiffening and withstand torsion via all other interconnected concrete flow bridges, characterized by the feeling of walking on solid ground.
Opfindelsens baggrundBACKGROUND OF THE INVENTION
Betonflydebroer er beton elementer på fx 2 - 5 m i bredden og fx 6 - 25 m i længden og fx 80 - 200 cm i højden, hvor elementerne har indstøbte polystyrenblokke til opdrift. Betonflydebroer anvendes som bådebroer i bl.a. havne samt marinaer og de sammenkobles i længderetning for at nå den ønskede længde på et broforløb.Concrete flow bridges are concrete elements, for example, 2 - 5 m in width and for example 6 - 25 m in length and eg 80 - 200 cm in height, where the elements have built-in polystyrene blocks for buoyancy. Concrete flow bridges are used as boat bridges in i.a. ports as well as marinas and they are connected longitudinally to reach the desired length of a bridge course.
De i dag kendte metoder til sammenkobling af betonflydebroer går ud på at man i hvert hjørne af betonflydebroen skal lave udsparinger til indbygning af dele til sammenspænding af brofagene i længderetningen.The methods known today for interconnecting concrete flow bridges are to make recesses in each corner of the concrete flow bridge to incorporate parts for longitudinal tensioning of the bridges.
Udsparingen udføres normalt ved at der indstøbes en galvaniseret stålkasse hvor der kan være svejset et trækrør, som forbinder kassen med en galvaniseret rørskål for placering af neoprene stødklods og trækning af specialfremstillet stålwire. Når elementerne er søsat og skal sammenkobles i længderetningen føres en specialfremstillet stålwire med gevindstykker i begge ender gennem trækrøret i de to brofag der skal sammenkobles, der monteres nu spændplade og møtrik i begge ender og brofagene kan spændes sammen omkring en neoprene stød klods der hviler i de to modstående rørskåle.The recess is usually carried out by casting a galvanized steel box where there may be a welded pipe connecting the box to a galvanized pipe bowl for placement of neoprene shock pad and drawing of specially made steel wire. When the elements are launched and are to be connected longitudinally, a specially made steel wire with threaded ends at both ends is passed through the pull pipe in the two bridges to be connected, now mounted clamp plate and nut at both ends and the bridges can be clamped around a neoprene shock pad resting in the two opposing pipe bowls.
Udsparingskassen i flydebroen afdækkes med en trædefast dørkplade, der typisk fastgøres med 4 skruer.The recess box in the floating bridge is uncovered with a tread-resistant floor plate, which is typically fastened with 4 screws.
De kendte metoder er karakteristiske ved:The known methods are characterized by:
At materialefremstillingen udgøres af mange specielt fremstillede dele og dermed er dyr i fremstilling og indkøb.That the material manufacture is made up of many specially made parts and is thus expensive in manufacture and procurement.
At støbningen af et element kompliceres unødigt meget, idet der kræves tidskrævende indstøbninger/udsparinger af mange enkeltdele, hvor der bl.a. skal laves store og nødvendige tilpasninger af armering og armeringsforstærkninger.That the casting of an element is unnecessarily complicated, requiring time-consuming embedding / recesses of many individual parts. major and necessary adjustments to reinforcement and reinforcement reinforcements must be made.
At sammenkoblingen ikke yder samme signifikante support i forbindelse med flere sammenkoblede betonflydebroer, hvor fx et element belastes sidevejs ekstraordinært af fx bølger eller vægt.That the interconnection does not provide the same significant support in connection with several interconnected concrete flow bridges, where, for example, an element is loaded laterally by, for example, waves or weight.
At neopren klodserne i begge sider har en begrænset levertid og er dyre og besværlige at udskifte.The neoprene bricks on both sides have a limited delivery time and are expensive and cumbersome to replace.
At udskiftning af servicedele, fx neopren klodser, typisk kræver fagfolk og specielværktøj, hvorved det kendte system er meget besværligt, ufleksibelt og dyrt for brugeren/marina eller havn, da det kun kan serviceres af fagfolk med særligt værktøj.Replacement of service parts, eg neoprene bricks, typically requires professionals and special tools, whereby the known system is very cumbersome, inflexible and expensive for the user / marina or port, as it can only be serviced by professionals with special tools.
Opfindelsens formålThe object of the invention
At udvikle et koblingssystem der signifikant forenkler fremstilling/støbning af betonflydebroer.To develop a coupling system that significantly simplifies the production / casting of concrete flow bridges.
At udvikle et koblingssystem der er signifikant billigere i fremstilling/indkøb.To develop a coupling system that is significantly cheaper in manufacturing / purchasing.
At udvikle et koblingssystem der signifikant forenkler den efterfølgende sammenkobling af brofagene, uden brug af fagfolk eller specielværktøj.To develop a coupling system that significantly simplifies the subsequent interconnection of the bridge subjects, without the use of professionals or special tools.
At udvikle et koblingssystem, dersupportere flere sammenkoblede broers modstandskraft i forhold til vridningspåvirkninger fx i forbindelse med sidevejs påvirkning af fx bølger eller stor vægt.To develop a coupling system, support the resistance of several interconnected bridges in relation to torsional influences, for example in connection with lateral effects of, for example, waves or large weights.
At udvikle et koblingssystem der ikke kræver anvendelse af fx neoprene stød klodser imellem to sammenkoblede betonflydebroer, hvorved man sparer både dyrt indkøb og hyppig udskiftning af samme.To develop a coupling system that does not require the use of, for example, neoprene bumps between two interconnected concrete flow bridges, thereby saving both expensive procurement and frequent replacement of the same.
Det nye princip for sammenkobling af betonflydebroer som ønskes patenteret går i al sin enkelthed ud på at der i hver ende af flydebroen indstøbes 4 stk. inserts, fx M30, hvori der kan skrues tilsvarende antal øjebolte, hvorefter elementerne kan samles med to gennemgående dorne/bolte, fx M36, med låsesplit eller anden låseanordning, som vist på vedlagte skitse.The new principle for interconnecting concrete flow bridges, which is wanted to be patented, is in all its simplicity that at each end of the floating bridge is cast 4 pieces. inserts, eg M30, in which the corresponding number of eyebolts can be screwed, after which the elements can be joined by two through-holes / bolts, eg M36, with locking pin or other locking device, as shown in the attached sketch.
Den nye metode giver store fordele i forbindelse med opstilling af forme og udstøbning af elementerne.The new method offers great advantages in forming molds and molding the elements.
Med den i dag kendte metode starter man med at placere polystyrenblokkene, opbygge armeringsnet og stålforstærkninger, der begge skal forbedredes i forhold til de tidligere nævnte udsparinger. Undervejs i forløbet monteres formsider og formender, hvorefter man skal i gang med at indbygge forholdsvis mange og komplekse udsparinger med galvaniseret stålkasser, rør til stålwirerne, afløb fra galvaniseret stålkasse i alle fire hjørner af betonflydebroen, først da er klar til at støbe elementet. Udstøbningen kræver stor akkuratesse omkring de nævnte udsparinger for at sikre at betonen flyder sammen og overfladen omkring udsparingerne skal glittes i hånden.With the method known today, one starts by placing the polystyrene blocks, building reinforcement nets and steel reinforcements, both of which need to be improved in relation to the recesses mentioned earlier. During the process, mold sides and moldings are mounted, after which you must start to incorporate relatively many and complex recesses with galvanized steel boxes, pipes for the steel cables, drains from galvanized steel box in all four corners of the concrete flow bridge, only then ready to cast the element. The casting requires great accuracy around the recesses to ensure that the concrete flows together and the surface around the recesses must be glossed by hand.
Med den nye metode starter man med, at placere polystyrenblokkene, opbygge armeringsnet - uden hensyn til udsparinger, herefter rejses formsider og ender. I hver ende er der monteret 4 stk. koblingsinserts i formen, og man er nu klar til at udstøbe elementet. Udstøbningen er meget enkelt da man ikke skal tage hensyn til diverse komplicerede udsparinger, overfladen er helt glat og kan glittes med maskine.With the new method, you start by placing the polystyrene blocks, building reinforcement nets - regardless of recesses, then form sides and ends are raised. At each end 4 pieces are mounted. coupling inserts in the mold and you are now ready to cast the element. The casting is very simple as you do not have to take into account various complicated recesses, the surface is completely smooth and can be machine smooth.
