Fremgangsmåte for fremstilling av hull og slisser i Procedure for making holes and slits in
bygningsmateriale .building material.
Foreliggende oppfinnelse vedrører en fremgangsmåte for fremstillingThe present invention relates to a method for production
av hull som står omtrent vinkelrett på flaten eller rette eller sirkelformete slisser i yttersonene til rundvirke eller saget virke til omtrent en i forveien bestemt dybde for å lette inntrengningen av im<p>re<g>nerin<g>smidclel i yttersonene av virket for beskyttelse mot kjemiske og biologiske skader. of holes standing approximately perpendicular to the surface or straight or circular slits in the outer zones of round timber or sawn timber to approximately a predetermined depth to facilitate the penetration of im<p>re<g>nerin<g>smidclel into the outer zones of the timber for protection against chemical and biological damage.
Tømmer og lignende må beskyttes mot råte, mikrobeangrep og lignende,Timber and the like must be protected against rot, microbial attack and the like,
det vil si mot kjemisk og biologisk Ødeleggelse.that is, against chemical and biological destruction.
For dette formål er det kjent tilsvarende beskyttelsesmidler, særlig impregneringsmidler. Ved anvendelse av hensiktsmessige impregneringsmidler er det vanligvis tilstrekkelig for å få en tilstrekkelig beskyttelse, å la impregneringsmidlet trenge inn i virkets yttre sone, avhengig av tresorten i størrelsorden ca. 1-2 cm. En slik inntreng-ningsdybue kan vanligvis oppnås i fiberretningen ved de vanlige tre-slagene. I regelen oppnås imidlertid den nødvendige inntrengningsdybde for impregnéringsmidler på tvers av fiberretningen, med de vanlige impregneringsfremgangsmåter, selv når impregneringsmidlet føres inn under trykk, til og med når vannet i treet er blitt sugd ut på for- For this purpose, corresponding protective agents, in particular impregnation agents, are known. When using suitable impregnating agents, it is usually sufficient to obtain adequate protection, to let the impregnating agent penetrate into the outer zone of the wood, depending on the type of wood in the order of magnitude approx. 1-2 cm. Such a penetration depth can usually be achieved in the direction of the grain with the usual types of wood. As a rule, however, the required depth of penetration of impregnating agents across the fiber direction is achieved with the usual impregnating methods, even when the impregnating agent is introduced under pressure, even when the water in the wood has been sucked out on the pre-
hånd ved hjelp av undertrykk eller virket eller dets yttre soner på annen måte er blitt tørket før impregneringen, ikke eller utilstrekkelig, slik at selv impregnert virke over lenger tid ikke er beskyttet. hand by means of negative pressure or the timber or its outer zones have otherwise been dried before impregnation, not or insufficiently, so that even impregnated timber is not protected over a longer period of time.
For å øke impregneringsmidlenes inntrengningsdybde borjfer man derforIn order to increase the penetration depth of the impregnation agents, it is therefore necessary to
ved bunnvirke, for eksempel for telefonstolper og lignende, særlig innenfor det område som graves ned i marken og noe over dette, i hensiktsmessig avstand sirka 2 cm. dype hull radielt inn og oppnår derved at impregneringsmidlet trenger dypere inn og det oppstår en sammenhengende yttre sone med tilstrekkelig beskyttelses virkning mot kjemisk og biologisk ødeleggelse. Det er også kjent å øke impregnerings- in the case of groundwork, for example for telephone poles and the like, especially within the area that is dug into the ground and somewhat above this, at an appropriate distance of approximately 2 cm. deep holes radially in and thereby achieves that the impregnating agent penetrates deeper and a continuous outer zone with sufficient protective effect against chemical and biological destruction is created. It is also known to increase impregnation
midlenes inntrengningsdybde ved jernbanesviller og lignende ved å lage korte langsgående slisser, den såkalte "incising-metode". the agents' penetration depth at railway sleepers and the like by making short longitudinal slits, the so-called "incising method".
Det har imidlertid vist seg at ved ulike trevarer eller treslag, særlig ved sagvirke, må hullene sitte forholdsvis tett for at yttersonene skal fuktes tilstrekkelig dypt og sammenhengende. Det å fremstille en tett hulldeling mekanisk, for eksempel ved boring, er imidlertid meget kostbart og ikke økonomisk gjennomførbart og forårsaker også på grunn, av kvistdannelser tekniske vanskeligheter. Dessuten er tømmerets styrkereduksjon ved tett hulldeling betydelig. Samme forhold gjelder for runde eller avlange slisser når disse fremstilles mekanisk* However, it has been shown that with various wood products or types of wood, especially with sawn timber, the holes must be relatively close in order for the outer zones to be moistened sufficiently deeply and continuously. However, producing a tight hole division mechanically, for example by drilling, is very expensive and not economically feasible and also causes technical difficulties due to knot formations. In addition, the timber's strength reduction when the holes are closely spaced is significant. The same conditions apply to round or oblong slits when these are produced mechanically*
Oppfinnelsens oppgave er å skaffe en økonomisk fremgangsmåte for fremstilling av hmll eller rette eller sirkelformete slisser i de yttre sonene av rundt- eller sagvirke, som muliggjør en sammenhengende impregnering til tilstrekkelig dybde av yttersonene, med den vanlige fremgangsmåte for impregnering. The task of the invention is to provide an economical method for producing hmll or straight or circular slits in the outer zones of round or sawn timber, which enables a continuous impregnation to a sufficient depth of the outer zones, with the usual method of impregnation.
Dfctte oppnås ifølge oppfinnelsen ved at det avhengig av den ønskete hulldiameter eller slisstykkelse benyttes sammenholdte stråler med stor energi eller séor energitetthet for å slå istykker materialet i de hull eller slisser som skal dannes. Dfctte is achieved according to the invention in that, depending on the desired hole diameter or slit thickness, combined beams with high energy or high energy density are used to smash the material in the holes or slits to be formed.
Strålene med høy energi for ødeleggelse av materialet i de kanaler som skal dannes, kan foreksempel være laserstråler som frembringes ved såkalt borlaser. The rays with high energy for destruction of the material in the channels to be formed can, for example, be laser rays produced by so-called boron lasers.
Det er imidlertid også mulig å ødelegge materialet ved gnisterosjon. However, it is also possible to destroy the material by spark erosion.
En annen mulighet for å slå istykker materialet er at man benytterAnother possibility for breaking the material into pieces is to use
en skarpt sammenholdt veskestråle med høy hastighetsenergi.a sharply coherent purse jet with high velocity energy.
Denne fremgangsmåten er serlig fordelaktig om man som væske benytter det impregnoringsmiudél som skal benyttes. This method is particularly advantageous if the liquid used is the impregnation medium to be used.
Siden stråler med høy energi eller energitetthet kan holdes skarpt sammenbundet, er det mulig å fremstille hull og slisser med liten Since beams of high energy or energy density can be kept sharply connected, it is possible to produce holes and slits with small
diameter Henholdsvis liten slissbredde, slik at hullene eller slissene kan settes relativt tett uten at tømmerets styrke reduseres utover en akseptabel verdi og på grunn av den tette hull - eller slissdelingen blir en sammenhengende impregnering av tømmerets yttre soner mulig og virket derved tilstrekkelig beskyttet mot kjemisk og biologisk diameter Correspondingly small slit width, so that the holes or slits can be placed relatively close together without the timber's strength being reduced beyond an acceptable value and due to the tight hole or slit division, a continuous impregnation of the timber's outer zones becomes possible and thereby appears sufficiently protected against chemical and biologically
ødeleggelse.destruction.
Siden fremstillingen av hullene eller slissene i tømmerets ytter-soner skjer med høy arboidshastighet er den beskrevne fremgangsmåte også økonomisk sammenlignet med mekaniske fremgangsmåter. Since the production of the holes or slits in the timber's outer zones takes place at a high arboid speed, the described method is also economical compared to mechanical methods.
