Abstract

A method of fixing sheet metal sections and wooden bars or boards relative to each other, which latter transversely to the longitudinal direction of the sheet metal sections can be inserted into holes punched in the sheet metal sections, at which method after the boards have been inserted into intended holes and after the positions and angles for the sheet metal sections and boards have been aligned relative to each other, the sheet metal sections are pressed together about the boards, so that the sheet metal section after the removal of the pressing force assumes a permanent deformation, while the inserted board or boards elastically spring back so that section and wood permanently are pressed against each other.

Description

Foreliggende oppfinnelse angår en fremgangsmåte for innbyrdes forbindelse av plateprofiler med trestaver eller bord som er innstukket på tvers av plateprofilenes lengderetning i hull som er utstanset i disse. The present invention relates to a method for interconnecting plate profiles with wooden rods or boards which are inserted across the longitudinal direction of the plate profiles into holes punched in them.

Oppfinnelsen har først og fremst til oppgave å muliggjøre stakittmoduler bestående av horisontale lossholter som utgjøres av plateprofilene og vertikale bord. For ut-nyttelse av fremgangsmåten ved fremstilling av stakittmoduler, skal om mulig flere ønskemål være oppfylt. For det første skal fremgangsmåten være økonomisk. Videre skal forbindelsene være sterke for å motstå de påkjenninger som oppstår f.eks. når barn eller voksne støtter seg til og klatrer på stakittet og egenvekten og snebelastning må ikke bringe stakittet til å kroke seg med årene. Det er videre ønskelig at -stakittet om nødvendig skal kunne skråstilles noe for tilpassing til eventuell bakkehelling. Helst skal denne til-passingen kunne skje ved monteringen, men man kan naturligvis også tenke seg ved kraftigere helning å fremstille stakittmodulene vinklet i motsvarende grad. Heller ikke må vær og vind resultere i at stakittet går i stykker. The invention's primary task is to enable picket modules consisting of horizontal bulkheads made up of the plate profiles and vertical boards. In order to use the method in the production of picket modules, if possible, several requirements must be met. Firstly, the procedure must be economical. Furthermore, the connections must be strong to withstand the stresses that arise, e.g. when children or adults lean on and climb the fence and the own weight and snow load must not cause the fence to buckle over time. It is also desirable that, if necessary, the picket fence should be able to be tilted somewhat to adapt to any slope of the ground. Ideally, this adaptation should be possible during assembly, but one can of course also think of making the picket modules angled to a corresponding degree in the event of a steeper slope. Nor must weather and wind result in the fence breaking.

Ovenstående oppgaver løses ifølge oppfinnelsen ved at plateprofilen eller -profilene presses sammen mot bordene etter at disse er stukket inn i hull i plateprofilene og etter innrettet av bordene og plateprofiler i nød-vendige vinkler og stillinger, slik at det oppnås varig deformasjon av plateprofilen, idet bordene etter at presse-kraf ten er fjernet fjærer elastisk tilbake, slik at profil og treverk får en innbyrdes forspenning som forbinder den innbyrdes. According to the invention, the above tasks are solved by the plate profile or profiles being pressed together against the tables after these have been inserted into holes in the plate profiles and after the tables and plate profiles have been arranged in the necessary angles and positions, so that permanent deformation of the plate profile is achieved, as the boards, after the pressing force has been removed, spring back elastically, so that the profile and wood have a mutual pretension that connects them to each other.

I en videreutvikling av oppfinnelsestanken somIn a further development of the idea of invention which

er meget velegnet for stakitt, kan plateprofilen ha et tverrsnitt med en kontur i likhet med et hus med sadeltak, dvs. med to mer eller mindre vertikale sideflenser og en V-formet midtdel med spissen rettet oppover. På denne måte kommer ved plateprofilens sammenpressing deformasjonen til å skje i V-delens spiss, slik at profilen også etter den deformerende sammenpressingen har et likeformet utseende. is very suitable for picket fences, the plate profile can have a cross-section with a contour similar to a house with a gable roof, i.e. with two more or less vertical side flanges and a V-shaped central part with the tip directed upwards. In this way, when the plate profile is compressed, the deformation takes place at the tip of the V part, so that the profile also has a uniform appearance after the deforming compression.

For ytterligere å forsterke forbindelseskraften mot forskyvning av bordene i irespektive hull, kan det være hensiktsmessig at hullets kanter er noe innbrettet, slik at ved sammenpressingen disse presses inn i treet med en større eller mindre lokal deformasjon av treverket som følge. Det er da ikke nødvendig at den i .treverket inngripende kanten er rett, men man kan tenke seg en eller flere små tagger eller fliker som stikker inn i hullet og gir det ønskede ekstra grepet. Særlig om man ønsker et stakitt som kan skråstilles noe ved sin endelige montering, kan det være hensiktsmessig å la den inn i treet inngripende delen av hullkantene bare utgjøres av ett eneste kortere stykke ved hullets midtdel, slik at innstukkende bord utsettes for et middels motholdende moment når stakittmodulen forskyves for tilpassing til bakkehellingen. In order to further strengthen the connection force against displacement of the boards in non-respective holes, it may be appropriate that the edges of the holes are slightly folded in, so that during the compression these are pressed into the wood with a greater or lesser local deformation of the wood as a result. It is then not necessary that the edge that engages in the wood is straight, but you can imagine one or more small tags or tabs that stick into the hole and provide the desired extra grip. In particular, if you want a fence that can be tilted somewhat during its final assembly, it may be appropriate to let the part of the hole edges that engages into the wood only be made up of a single shorter piece at the middle part of the hole, so that the inserted boards are exposed to a medium resisting moment when the fence module is shifted to adapt to the slope of the ground.

Innenfor oppfinnelsens ramme kan man naturligvis også tenke seg den ovennevnte profilen dublert, dvs. med en likedan "husprofil" vendt nedover og direkte tilsluttet den øvre.. Denne utførelse har imidlertid når det gjelder stakitter den ulempe at vann kan komme til å bli innesluttet i profilen dersom ikke f.eks. de nedre hullene i profilen gjøres større enn hva som kreves for bordenes innstikking. Within the framework of the invention, one can of course also imagine the above-mentioned profile duplicated, i.e. with a similar "house profile" facing downwards and directly connected to the upper one. the profile if not e.g. the lower holes in the profile are made larger than what is required for the boards to be inserted.

Ved at profilens høyde eller kanskje snarere høydene på sideflensene ikke har noen større innvirkning på hvor godt grepet mellom treverk og plateprofil blir, så kan flenshøyden tillates å bli bestemt utelukkende av styrke-egenskapen i vertikal retning (det er i denne retning som stakittet risikerer å bli utsatt for de største påkjenninger ved klatring etc), samtidig som stakittets tverrdimensjoner kan holdes begrensede. Since the height of the profile, or perhaps rather the height of the side flanges, has no major impact on how well the grip between wood and plate profile is, the flange height can be allowed to be determined exclusively by the strength property in the vertical direction (it is in this direction that the fence risks be exposed to the greatest stresses when climbing etc), while the cross dimensions of the fence can be kept limited.

Oppfinnelsen skal i det følgende beskrives nær-mere under henvisning til et på tegningen vist praktisk ut-førelseseksempel på oppfinnelsen. In the following, the invention will be described in more detail with reference to a practical embodiment of the invention shown in the drawing.

Fig. 1 viser i perspektiv en del av et stakitt ifølge oppfinnelsen , Fig. 1 shows in perspective part of a picket fence according to the invention,

fig. 2 viser forbindelsen ifølge oppfinnelsen i snitt. fig. 2 shows the compound according to the invention in section.

fig. 3 og fig. 4 viser ytterligere detaljer i det i fig. 1 viste stakitt. fig. 3 and fig. 4 shows further details in that in fig. 1 showed picket fence.

Det i fig. 1 viste stakitt omfatter en horison-talt liggende plateprofil 1 av hvilken bare et kort stykke er vist. I plateprofilen er det presset fast en trestav 2 ved at plateprofilen er klemt sammen omkring trestaven. Dette er vist tydeligere i fig. 2, der man ser hvorledes plateprofilene 1 ved sammenpressingen har brettet seg ytterligere ved vinkelspissen 3, slik at de på begge sider av bordet eller trestaven 2 beliggende flikene eller kantene 4 resp. 5 for hullet i plateprofilen er blitt innpresset i treet. That in fig. The fence shown in 1 comprises a horizontally lying plate profile 1 of which only a short section is shown. A wooden rod 2 has been pressed into the plate profile by the plate profile being clamped around the wooden rod. This is shown more clearly in fig. 2, where you can see how the sheet profiles 1 have folded further at the angle tip 3 during the compression, so that the tabs or edges 4 or edges 4 located on both sides of the table or wooden stick 2 5 for the hole in the plate profile has been pressed into the wood.

Fig. 1 viser også en av to identiske profiler 6 og 7 sammensatte stakittstolpe. I profildelene 6 og 7 er det gjort utsparinger slik at det kan innsettes V-formet bukkede elementer 8 som i lengderetningen er forbundet ved hjelp av utsparinger 9 og 10 som griper om stolpeprofilene 6 og 7. Når siden stakittet skal monteres, opplegges profilen 1 helt enkelt på det V-formede elementet 8 og forbindes mot avløfting ved at en hylse 11, som før monteringen er skjøvet inn på plateprofilen 1, skyves til an-legg mot stolpen, i hvilken stilling den kan forbindes på en hvilken som helst ønskelig måte, f.eks. ved hjelp av en eller annen form for snepplås. For å holde sammen den av profilene 6 og 7 frembragte stolpen, kan det i den øvre enden være Fig. 1 also shows one of two identical profiles 6 and 7 composite picket post. In the profile parts 6 and 7, recesses have been made so that V-shaped bent elements 8 can be inserted, which are connected in the longitudinal direction by means of recesses 9 and 10 that grip the post profiles 6 and 7. When the side fence is to be assembled, the profile 1 is laid completely simply on the V-shaped element 8 and is connected against lifting by a sleeve 11, which before assembly has been pushed onto the plate profile 1, is pushed to rest against the post, in which position it can be connected in any desired way, e.g. using some form of snap lock. In order to hold together the post produced by the profiles 6 and 7, it can be at the upper end

anordnet et lokk som griper over utspring 12 resp.13 i profilenes øvre ender. Lokket kan enten kneppes på eller sneppe over utspringene 12,13, alternativt kan lokket 14 monteres på den i fig. 3 viste måte, dvs. utspringene 12, 13 hukes inn hvoretter stolpedelene 6 og 7 føres sammen for siden å nedsettes f.eks. i en bakkeforankring 15 av den i fig. 4 viste art. Naturligvis kan man i stedet for forankringsdelen 15 støpe fast stolpen i betong på kjent måte, men dette er i alminnelighet en dyrere metode på grunn av at den er mere tidkrevende. provided with a lid that grips over protrusions 12 or 13 at the upper ends of the profiles. The lid can either be buttoned on or snapped over the protrusions 12,13, alternatively the lid 14 can be mounted on the one in fig. 3, i.e. the protrusions 12, 13 are bent in, after which the post parts 6 and 7 are brought together for the side to be lowered, e.g. in a ground anchorage 15 of the one in fig. 4 showed art. Naturally, instead of the anchoring part 15, the post can be cast in concrete in a known manner, but this is generally a more expensive method because it is more time-consuming.
