Description
458 538 10 15 20 25 30 35 f: ingående metallkonstruktionen och i högra halvan av den kompletta ställningstrallen samt FIG 4 är en fragmentarisk perspektivbild av ställningstrallens ändparti. 458 538 10 15 20 25 30 35 f: comprising the metal structure and in the right half of the complete scaffolding beam and FIG. 4 is a fragmentary perspective view of the end portion of the scaffolding beam.
Den på ritningen visade ställningstrallen är av kompositkonstruktion och innefattar två längsgående kantbalkar 10 med lådformig profil och två mellan kantbalkarna anordnade plåtar 11, som befinner sig på inbördes avstånd. Kantbalkarna skall i det före- dragna utförandet bestå av ett material, vars elas- ticitetsmodul är större än elasticitetsmodulen för materialet i plåtarna för att ge ställningstrallen erforderlig styvhet. Lämpligen består kantbalkarna av stål, varvid de bör vara ytbehandlade, exempelvis förzinkade och aluminiserade, för förhindrande av korrosion, medan plåtarna lämpligen består av alumi- nium, som har en elasticitetsmodul, vilken är ca 1/3 av stålets elasticitetsmodul (ca 7000 resp ca 21000 kg/mmz). Plåtarna är utformade med hakformiga kantpartier 12 och är med dessa kantpartier i in- grepp med hakformiga kantpartier 13 på kantbalkarna.The scaffold shown in the drawing is of composite construction and comprises two longitudinal edge beams 10 with a box-shaped profile and two plates 11 arranged between the edge beams, which are spaced apart from each other. In the preferred embodiment, the edge beams shall consist of a material, the modulus of elasticity of which is greater than the modulus of elasticity of the material in the plates in order to give the scaffold the required rigidity. The edge beams suitably consist of steel, whereby they should be surface-treated, for example galvanized and aluminized, to prevent corrosion, while the plates suitably consist of aluminum, which has a modulus of elasticity, which is about 1/3 of the modulus of elasticity of the steel (approx. 7000 and approx. 21000 kg / mm2). The plates are formed with hook-shaped edge portions 12 and are with these edge portions in engagement with hook-shaped edge portions 13 on the edge beams.
Kantbalkarna och plåtarna avgränsar ett hålrum 14, som sträcker sig genomgående mellan plåtarna in i lådbalkarna, 3, och detta material 15. såsom framgår av vänstra halvan av FIG hålrum är utfyllt med ett styvt skum- såsom framgår av högra halvan av FIG 3, lämpligen ett skumplastmaterial, såsom freonfritt styvt polyuretanskum med en densitet på 55 kg/m3.The edge beams and plates define a cavity 14, which extends continuously between the plates into the box beams, 3, and this material 15. as can be seen from the left half of FIG. Cavities are filled with a rigid foam - as can be seen from the right half of Fig. 3, suitably a foam material, such as freon-free rigid polyurethane foam with a density of 55 kg / m3.
I förhållande-till freonskum har det freonfria skum- met sämre K-värde. men denna faktor saknar betydelse i samband med en ställningstrall, varför miljösyn- I punkter får överväga vid valet av skumplastmaterial. l Förutom att styva upp den av kantbalkarna och plå- tarna bildade lådkonstruktionen åstadkommer skum- plastmaterialet även fixering av ingreppet mellan de 10 15 20 25 30 35 458 538 hakformiga partierna 12 och 13, varvid fixeringen blir särskilt effektiv, om de hakformiga partierna är anordnade i sned vinkel, huvudsakligen 45° vinkel, mot plàtarnas plan, sàsom i det här visade utförandet. Styvheten hos den som kompositkonstruk- tion utförda ställningstrallen ökas ytterligare genom att den övre pläten är utförd som rillad plät - lämpligen med breda grunda rillor, sàsom visas pà ritningen - varvid lämpligen även den undre pláten är utförd pä samma sätt, även om rillningen hos denna plät inte har nagon inverkan pà styvheten; det är emellertid fördelaktigt att bygga upp ställ- ningstrallen av identiska element, sä längt detta är möjligt.In relation to freon foam, the freon-free foam has a lower K-value. but this factor is irrelevant in connection with a scaffolding, which is why environmental considerations may be considered in the choice of foam material. In addition to stiffening the box construction formed by the edge beams and the plates, the foam plastic material also provides fixation of the engagement between the hook-shaped portions 12 and 13, the fixing being particularly effective if the hook-shaped portions are arranged at an oblique angle, mainly a 45 ° angle, towards the plane of the plates, as in the embodiment shown here. The rigidity of the scaffold made as a composite structure is further increased in that the upper plate is made as a grooved plate - preferably with wide shallow grooves, as shown in the drawing - whereby the lower plate is suitably made in the same way, even if the groove of this the plate has no effect on the stiffness; however, it is advantageous to build up the scaffolding of identical elements, as far as possible.
Vardera kantbalken bildar pà ovansidan en kant- sarg 16, och mellan kantsargerna är ställnings- trallen pä sin ovansida försedd med en ytbeläggning 18, vars tjocklek motsvarar kantsargernas höjd, varigenom kantsargerna hindrar uppsparkning av ytbe- läggningen. Lämpligen utgöres ytbeläggningen av en gummiduk, som efter konditionering av ytan pä kant- balkarnas och den övre plätens översida har fastvul- kats pä denna. Fastvulkningen kräver en temperatur pà cirka 1600C, och uppvärmning av ställnings- trallen till denna temperatur medför inga skadliga effekter, eftersom polyuretanskummet pâverkas först vid cirka 200°C. Ytbeläggningen bildar ett halk- skydds- och slitskikt pa ställningstrallen och skyd- dar dessutom den övre pläten mot genombrytning. exempelvis om något tungt och spetsigt föremål skulle tappas pà ställningstrallen. Dessutom är yt- beläggningen lätt att rengöra och behaglig att ga pà, vartill kommer, att den skyddar de hakformiga ingreppspartierna 12, 13 pà ställningstrallens över- sida mot inträngning av vatten och därav föranledd korrosion. 458 538 10 15 20 25 30 35 Ställningstrallen är i ändarna avslutad medelst ändkäpor 18 av plast, som tillsluter det med Skum- plastmaterial fyllda hälrummet i ställningstrallen i dennas ändar. Pà undersidan har ställningstrallen ett par företrädesvis gummiskodda urtagningar 19 i vardera kantbalken för upptagning av de stänger eller balkar i byggnadsställningen, pä vilka ställ- ningstrallen skall vara upplagd. Flera ställnings- trallar uppradas bredvid varandra pä dessa stänger eller balkar för att bilda ett våningsplan i bygg- nadsställningen. Slutligen skall nämnas, att vardera kantbalken pà sin insida är utformad med en längs- gående, rännformig inbuktning 20, varigenom kant- balken tjänar som handtag, för att ställningstrallen bekvämt skall kunna bäras och hanteras.Each edge beam forms an edge rim 16 on the upper side, and between the edge edges the scaffolding trolley is provided on its upper side with a surface coating 18, the thickness of which corresponds to the height of the edge edges, whereby the edge edges prevent kick-up of the surface coating. Suitably, the surface coating consists of a rubber cloth, which after conditioning the surface on the upper side of the edge beams and the upper plate has been folded onto it. The solidification requires a temperature of about 1600C, and heating the scaffolding to this temperature does not cause any harmful effects, since the polyurethane foam is only affected at about 200 ° C. The surface coating forms a non-slip and wear layer on the scaffolding and also protects the upper plate against penetration. for example, if a heavy and pointed object were to be dropped on the scaffolding. In addition, the surface coating is easy to clean and comfortable to wear, in addition to which it protects the hook-shaped engaging portions 12, 13 on the upper side of the scaffolding trolley against the penetration of water and consequent corrosion. 458 538 10 15 20 25 30 35 The scaffolding trolley is terminated at the ends by means of end caps 18 of plastic, which close the cavity filled with foam plastic material in the scaffolding trolley at its ends. On the underside, the scaffolding trolley has a pair of preferably rubber-coded recesses 19 in each edge beam for receiving the bars or beams in the scaffolding on which the scaffolding trolley is to be supported. Several scaffolding trolleys are lined up next to each other on these poles or beams to form a floor plan in the scaffolding. Finally, it should be mentioned that each edge beam on its inside is formed with a longitudinal, gutter-shaped indentation 20, whereby the edge beam serves as a handle, so that the scaffolding can be comfortably carried and handled.
Vid tillverkningen av den beskrivna ställnings- trallen med tillämpning av sättet enligt uppfin- ningen förfar man pà följande sätt. Sedan kantbal- karna 10 och de bada plätarna 11 har bragts i in- grepp med varandra vid de hakformiga partierna 12, 13 i en fixtur, medelst vilken delarna hàlles i läge och i inbördes ingrepp, anbringas de bada ändlocken 18 för tillslutning av det av kantbalkarna, plätarna och ändlocken bildade hàlrummet 14. I det ena änd- locket är därvid anordnat ett häl, och genom detta häl införes ett munstycke för injicering av kompo- nenterna till det styva skumplastmaterial 15, som skall inga i ställningstrallens konstruktion. Dessa komponenter förskummas i hälrummet 14 ooh utfyller detta för att sedan härda pä plats i hälrummet. När denna härdning sker, fixeras ingreppet vid de hak- formiga partierna 12, 13. Hälet i det nämnda ena ändlocket tillslutes därefter lämpligen med en plastpropp. Sedan ställningstrallen uttagits ur fix- turen, appliceras ytbeläggningen 17 pä ställnings- trallens ovansida.In the manufacture of the described scaffolding trolley using the method according to the invention, the procedure is as follows. After the edge beams 10 and the bath plates 11 have been brought into engagement with each other at the hook-shaped portions 12, 13 in a fixture, by means of which the parts are kept in position and in mutual engagement, the bath end caps 18 are applied to close it by the edge beams, the plates and the end caps formed the cavity 14. In one end cap a heel is arranged, and through this heel a nozzle is inserted for injecting the components into the rigid foam plastic material 15, which should not be present in the construction of the scaffold. These components are foamed in the heel cavity 14 ooh fill this to then cure in place in the heel cavity. When this hardening takes place, the engagement is fixed to the hook-shaped portions 12, 13. The heel in the said one end cover is then suitably closed with a plastic plug. After the scaffolding trolley has been removed from the fixture, the surface coating 17 is applied to the top of the scaffolding trolley.
