Description
Den foreliggende oppfinnelse vedrører et gulvelement for stillas, der gulvelementet ved hver ende har et opphengsområde beregnet til å hvile på en stillasbjelke, der gulvelementet har et flertall av langstrakte armeringsprofiler som er innstøpt i langsgående ribber på gulvelementets underside, der det mellom naboliggende ribber er anbrakt støtteribber, og der gulveelementets gangflate, ribbene og støtteribbene er enhetlig dannet av et komposittplastmateriale. The present invention relates to a floor element for scaffolding, where the floor element at each end has a suspension area intended to rest on a scaffolding beam, where the floor element has a plurality of elongated reinforcement profiles which are embedded in longitudinal ribs on the underside of the floor element, where it is placed between neighboring ribs support ribs, and where the floor element's walking surface, the ribs and the support ribs are uniformly formed from a composite plastic material.
Et slikt gulvelement for stillas er kjent fra WO 01704437-Al. Such a floor element for scaffolding is known from WO 01704437-Al.
Det er fra tidligere kjent å anbringe gulvelementer av denne type på stillasbjelker ved at disse hviler på en toppkant av de langsgående stillasbjelkene og ofte strekker seg noe utenfor disse bjelkenes utadvendende side. Ved en slik løsning blir oftest nødvendig å sikre gulvelementene mot glidebevegelser i forhold til bjelkene og dette kan eventuelt skje ved haker eller lignende som stikker ned fra gulvelementenes underside. Dette be-tyr i sin tur at når slike gulvelementer stables i høyden for transport, vil slike sikrings-innretninger oppta vesentlig lagringsplass, samtidig som gulvelementene ved montering har lett for å hake seg i hverandre. It is previously known to place floor elements of this type on scaffolding beams in that these rest on a top edge of the longitudinal scaffolding beams and often extend somewhat beyond the outward facing side of these beams. With such a solution, it is often necessary to secure the floor elements against sliding movements in relation to the beams, and this can possibly happen by means of hooks or the like that stick down from the underside of the floor elements. This, in turn, means that when such floor elements are stacked high for transport, such security devices will take up significant storage space, while the floor elements can easily snag on each other during assembly.
Den foreliggende oppfinnelse tilsikter på en enkel måte å avhjelpe de hittil kjente ulemper ved slike gulvelementer for stillas, og i følge den foreliggende oppfinnelse kjennetegnes oppfinnelsen ved at respektive endepartier av nevnte profiler danner nevnte opphengsområde ved anlegg mot respektive av de motsatte stillasbjelker, og at nedragende støttestykker er anordnet ved hver ende av gulvelementet i samvirke med nevnte profiler for å begrense bevegelse av gulvelementet i forhold til de motsatte stillasbjelker når disse bærer gulvelementet. The present invention aims in a simple way to remedy the hitherto known disadvantages of such floor elements for scaffolding, and according to the present invention, the invention is characterized by the fact that respective end parts of said profiles form said suspension area by contact with each of the opposite scaffolding beams, and that downward support pieces are arranged at each end of the floor element in cooperation with said profiles to limit movement of the floor element in relation to the opposite scaffold beams when these support the floor element.
Med fordel er det nevnte plastmaterialet dannet av poleolyfinmateriale, for eksempel kopolymer polypropylen, tilsatt et mineralmateriale, idet plastmaterialet ved støpning også er tilsatt et ekspansjonsmiddel. Andelen av mineralmaterialet er 10 - 40%, fortrinnsvis 20%, og mineralmaterialet er med fordel dolomitt. Ekspansjonsmaterialet kan tilsettes i en mengde lik 1 - 5 vektprosent, fortrinnsvis 2 vektprosent. Advantageously, the aforementioned plastic material is formed from polyolefin material, for example copolymer polypropylene, with a mineral material added, as the plastic material is also added with an expansion agent during casting. The proportion of the mineral material is 10 - 40%, preferably 20%, and the mineral material is advantageously dolomite. The expansion material can be added in an amount equal to 1 - 5 percent by weight, preferably 2 percent by weight.
Ifølge ytterligere utførelsesform av gulvelementet er armeringsprbfilen i gulvelementet skjøtbare med armeringsprofiler i et i lengderetning mellomliggende eller tilliggende gulvelement. According to a further embodiment of the floor element, the reinforcement test file in the floor element can be joined with reinforcement profiles in a longitudinally intermediate or adjacent floor element.
Ifølge enda en ytterligere utførelsesform kan gulvelementet være oppdelbart i minst to deler for innfelling av ett eller flere skjøtestykker som har et flertall av langstrakte armeringsprofiler som er innstøpt i langsgående ribber på skjøtestykkets underside, og der skjøtestykkets gangflate, ribbene og eventuelle støtteribber er enhetlig dannet av nevnte komposittmateriale. Skjøtestykket danner dermed mekanisk forbindelse med tilliggende gulvelementdel ved skjøting mellom gulvelementdelens armeringsprofiler og skjøte-stykkets armeringsprofiler. According to yet another embodiment, the floor element can be divisible into at least two parts for embedding one or more joint pieces which have a plurality of elongated reinforcement profiles which are embedded in longitudinal ribs on the underside of the joint piece, and where the walking surface of the joint piece, the ribs and any support ribs are uniformly formed by said composite material. The joint piece thus forms a mechanical connection with the adjacent floor element part by joining between the floor element part's reinforcement profiles and the joint piece's reinforcement profiles.
Oppfinnelsen skal nå nærmere forklares under henvisning til vedlagte tegninger som viser typiske for oppfinnelsen ikke med begrensende utførelseseksempler. The invention will now be explained in more detail with reference to the attached drawings which show typical non-limiting examples of the invention.
Figur 1 viser i perspektiv ovenfra et gulvelement, ifølge oppfinnelsen. Figure 1 shows in perspective from above a floor element, according to the invention.
Figur 2 viser gulvelementet, ifølge oppfinnelsen sett fra undersiden. Figure 2 shows the floor element, according to the invention seen from the underside.
Figur 3 viser et utsnitt av gulvelementet sett fra undersiden. Figure 3 shows a section of the floor element seen from the underside.
Figur 4 viser skjøteprinsipp for et gulvelement, ifølge oppfinnelsen. Figure 4 shows the joining principle for a floor element, according to the invention.
Figur 5 viser anvendelse av gulvelementet til bruk på et stillas. Figure 5 shows application of the floor element for use on a scaffold.
På figur 1 er vist et gulvelement 1 for stillas 24 (figur 5). Gulvelementet har ved hver ende et opphengsområde 2,3 som er beregnet til å hvile på en stillasbjelke, slik som angitt på figur 5. Opphengsområdene 2,3 har respektive, nedragende støttestykker 2', 3' ved hver ende for dermed å kunne begrense bevegelse av gulvelementet 1 i forhold til de motsatte stillasbjelker 25, 26, når disse understøtter gulvelementet, slik som vist på figur 5. Som vist både på figur 1 og figur 2 har gulvelementet et flertall av langstrakte armeringsprofiler 4,5, 6, for eksempel rør med sirkulært tverrsnitt, som er innstøpt i langsgående ribber 7, 8, 9 på gulvelementets underside 1', slik som vist på figur 2. Mellom de naboliggende, langsgående ribber 7, 8,9 er det med fordel anbrakt et flertall av respektive støtteribber 10, 11. Figure 1 shows a floor element 1 for scaffolding 24 (figure 5). The floor element has at each end a suspension area 2,3 which is intended to rest on a scaffolding beam, as indicated in figure 5. The suspension areas 2,3 have respective downward supporting pieces 2', 3' at each end in order to limit movement of the floor element 1 in relation to the opposite scaffolding beams 25, 26, when these support the floor element, as shown in Figure 5. As shown in both Figure 1 and Figure 2, the floor element has a majority of elongated reinforcement profiles 4,5, 6, for example pipes with a circular cross-section, which is embedded in longitudinal ribs 7, 8, 9 on the floor element's underside 1', as shown in Figure 2. Between the neighboring longitudinal ribs 7, 8, 9, a plurality of respective support ribs 10 are advantageously placed , 11.
Gulvelementets gangflate 12, ribbene 7-9 og støtteribbene 10, 11 er, ifølge oppfinnelsen enhetlig dannet av et kompositt-plastmateriale. Respektive endepartier 4', 5', 6' av de nevnte profiler 4,5, 6 vil primært danne opphengsområdet 2, 3 for gulvelementet ved anlegg mot overkant av respektive av de motsatte stillasbjelker 25, 26. Støttestykkene 2', 3' er festet for eksempel ved sveising eller nagling 30 - 32 til de respektive profiler 4, 5,6. The floor element's walking surface 12, ribs 7-9 and support ribs 10, 11 are, according to the invention, uniformly formed from a composite plastic material. Respective end parts 4', 5', 6' of the aforementioned profiles 4, 5, 6 will primarily form the suspension area 2, 3 for the floor element in contact with the upper edge of each of the opposite scaffold beams 25, 26. The support pieces 2', 3' are attached for example by welding or riveting 30 - 32 to the respective profiles 4, 5, 6.
Gulvelementets plastmateriale er med fordel dannet av et poleolyfinmateriale, for eksempel kopolymer polypropylen. Plastmaterialet er videre med fordel tilsatt et mineralmateriale og ved støpningen også tilsatt et ekspansjonsmiddel. Andelen av mineralmaterialet i plastmaterialet er fortrinnsvis 10 - 40%, mest foretrukket 20%. The floor element's plastic material is advantageously formed from a polyolefin material, for example copolymer polypropylene. The plastic material is further advantageously supplemented with a mineral material and, during casting, also with an expansion agent. The proportion of the mineral material in the plastic material is preferably 10 - 40%, most preferably 20%.
Mineralmaterialet som tilsettes plastmaterialet er med fordel dolomitt, og det nevnte ekspansjonsmaterialet blir tilsatt plastmaterialet i en mengde lik 1 - 5 vektprosent, fortrinnsvis 2 vektprosent. The mineral material that is added to the plastic material is advantageously dolomite, and the aforementioned expansion material is added to the plastic material in an amount equal to 1 - 5 percent by weight, preferably 2 percent by weight.
Det vil være en fordel at gulvelementer kan skjøtes for å øke deres lengde. Dette er an-tydet på figur 4 der det er vist et gulvelement som er oppdelt i 2 deler 15,16 og med armeringsprofiler 4", 5", 6". Disse armeringsprofiler 4", 5", 6" er innrettet til å være skjøt-bare med armeringsprofiler i et i lengderetning 15 mellomliggende eller tilliggende gulvelement 13, og der gulvelementets 13 armeringsprofiler er angitt med respektive henvisningstall 17, 18, 19. Dersom gulvelementet 13 skal innskjøtes mellom gulvele-mentdelene 15,16 kan det skje som angitt med pilene A og B. Dersom skjøting eventuelt ønskes fra et endeparti av elementene 15, 16, slik som ved en stillasbjelke, kan dette skje ved områdene A' eller B' med de respektive partier A eller B av elementet 13. It would be an advantage that floor elements can be joined to increase their length. This is indicated in figure 4, where a floor element is shown which is divided into 2 parts 15,16 and with reinforcing profiles 4", 5", 6". These reinforcing profiles 4", 5", 6" are designed to be can be joined with reinforcement profiles in an intermediate or adjacent floor element 13 in the longitudinal direction 15, and where the reinforcement profiles of the floor element 13 are indicated with respective reference numbers 17, 18, 19. If the floor element 13 is to be inserted between the floor element parts 15,16, it can be done as indicated with arrows A and B. If joining is desired from an end part of the elements 15, 16, such as in the case of a scaffolding beam, this can take place at the areas A' or B' with the respective parts A or B of the element 13.
De langstrakte armeringsprofilene 17, 18, 19 er innstøpt i langsgående ribber 20,21, 22 på skjøtestykkets 13 underside. I likhet med gulvelementet 1 er skjøtestykkets gangflate 23, ribbene 20 - 22 og de eventuelle støtteribber 24, 25 enhetlig dannet av det foran-nevnte komposittmateriale. Skjøtestykket 13 vil således kunne danne mekanisk forbindelse med tilliggende gulvelement del 1; 15; 16; med skjøting mellom gulvelementdelens armeringsprofiler 4", 5", 6" og skjøtestykkets armeringsprofiler 17 -19. The elongated reinforcement profiles 17, 18, 19 are embedded in longitudinal ribs 20, 21, 22 on the underside of the joint piece 13. Like the floor element 1, the joint's walking surface 23, the ribs 20 - 22 and the possible support ribs 24, 25 are uniformly formed from the above-mentioned composite material. The connecting piece 13 will thus be able to form a mechanical connection with the adjoining floor element part 1; 15; 16; with a joint between the floor element part's reinforcement profiles 4", 5", 6" and the joint's reinforcement profiles 17 -19.
På figur 5 er vist hvorledes stillaset kan oppbygges i utgangspunktet ved hjelp av gulvelement 1 stillasstolper 28, 29, stillastverrstykker 27 og langsgående bærebjelker 25, 26 som understøtter gulvelementet. Figure 5 shows how the scaffolding can be initially built up using floor element 1, scaffold posts 28, 29, scaffold cross members 27 and longitudinal support beams 25, 26 which support the floor element.
