Description
515 308 Syftet med föreliggande uppfinning är att åstadkomma en ny typ av distansorgan vid en sandwichkonstruktion, där ovannämnda nack- delar eliminerats och vid vilken en fullgod och optimal läges- fixering genom svetsning av distansorganen vid angränsande plåtar åstadkommits. De för uppfinningen utmärkande särdragen finns an- givna i efterföljande patentkrav. The object of the present invention is to provide a new type of spacer in a sandwich construction, in which the above-mentioned disadvantages have been eliminated and in which a satisfactory and optimal position fixing by welding of the spacers at adjacent plates has been achieved. The features characteristic of the invention are set out in the appended claims.
Tack vare uppfinningen har man nu åstadkommit en sandwich- konstruktion som på ett utmärkt sätt fyller sitt syfte samtidigt som den dessutom är både billig och lätt att tillverka. Såsom distansorgan för lågesfixeringen av de skivformade plåtelementen, som ingår i sandwichelementet, används enligt uppfinningen ett cylinderformat eller cylinderliknande rör som uppvisar ett fler- tal, på förutbestämda avstånd från. varandra. i rörets längd- riktning tvärgàende formationer~ bestående av' intryckningar i valbara vinklingar längs röret. Härigenom bildas från rörets mantelyta utskjutande vulster eller vårtor, som är avsedda att utgöra kontaktpunkter vid svetsningen. Även distansorgan næd andra former kan användas bara de uppvisar en sådan utformning att kontaktytorna mot intilliggande plåtar blir så liten som möjligt för underlättande av svetsning, vilket år en av förut- sättningarna för att svetsningsförloppet skall kunna. bli så gynnsamt som möjligt.Thanks to the invention, a sandwich construction has now been achieved which in an excellent way fulfills its purpose at the same time as it is also both cheap and easy to manufacture. According to the invention, a cylindrical or cylindrical tube having a plurality, at a predetermined distance from, is used as the spacer for the low-fixing of the disc-shaped plate elements, which are included in the sandwich element. each other. transverse formations in the longitudinal direction of the tube ~ consisting of indentations in selectable angles along the tube. As a result, bulges or warts protruding from the mantle surface of the pipe are formed, which are intended to form contact points during welding. Spacers other than other shapes can also be used as long as they have such a design that the contact surfaces against adjacent plates become as small as possible to facilitate welding, which is one of the prerequisites for the welding process to be able. be as favorable as possible.
Distansorganen kan före svetsningen ha utlagts i ett förutbestämt mönster i mellanrummet mellan plåtarna, varvid plåtarna därefter har pressats emot de genom deformationerna av distansorganet bildade, utskjutande vulsterna och fixerats vid dessa genom svetsningsoperationen, företrädesvis genom pressvetsning. Genom att kontaktytorna mellan de enligt uppfinningen formade distans- organen och angränsande plåtar före själva svetsningen år så liten, erhålles en mycket stark sammanfogning mellan distansorgan och plåtar. Vid användning av denna typ av distansorgan erhålles således en mycket säker svets mellan dessa och plåtarna, vilket i sin tur medför att sandwichelementet får en stor vrid- och böj- styvhet samtidigt som konstruktionen har liten vikt trots sin fauna 515 308 tjocklek och även uppvisar låg relativ densitet. Förutom den låga vikten kan svetspunkternas läge och mönster, varieras inom ett och samma element. Vidare kan man genom att variera godstjocklek på det rör som bildar distanselementet och att variera tillplatt- ningen av röret erhålla en optimal vàrta eller vulst; som formas i förhållande till plàttjockleken i täck- eller ytterskikten.The spacers may have been laid before welding in a predetermined pattern in the space between the plates, the plates then being pressed against the protruding beads formed by the deformations of the spacer and fixed thereto by the welding operation, preferably by press welding. Because the contact surfaces between the spacers formed according to the invention and adjacent plates before the actual welding are so small, a very strong connection between spacers and plates is obtained. When using this type of spacer, a very secure weld is thus obtained between these and the plates, which in turn means that the sandwich element has a large torsional and bending stiffness at the same time as the construction has little weight despite its fauna thickness and also has a low relative density. In addition to the low weight, the position and pattern of the welding points can be varied within one and the same element. Furthermore, by varying the wall thickness of the pipe forming the spacer element and by varying the flattening of the pipe, an optimal wart or bead can be obtained; which is formed in relation to the plate thickness in the cover or outer layers.
Till skillnad från homogena distanselement gär distanselementet enligt uppfinningen att tryckas samman vid efterföljande bearbetningsoperationer, såsom dragning, kantpress-ning, rullformning mm. Slutligen möjliggör distansorganen enligt uppfinningen att man kan använda ultrahöghällfasta metalliska, mindre formbara material i täckskikten.Unlike homogeneous spacer elements, the spacer element according to the invention tends to be compressed during subsequent machining operations, such as drawing, edge pressing, roll forming etc. Finally, the spacers according to the invention make it possible to use ultra-high-strength metallic, less moldable materials in the cover layers.
Anvândningsområdet för sandwichelementet innefattande distans- organ enligt föreliggande uppfinning kan vara såsom ett allmänt konstruktionselement och är mycket stort. Det kan exempelvis an- vändas till dörrplåt, flakplàt till lastbilar, tåg eller dylikt eller till väggar och golv i olika byggnadskonstruktioner.The field of application of the sandwich element comprising spacers according to the present invention can be as a general construction element and is very large. It can, for example, be used for door panels, flat panels for trucks, trains or the like or for walls and floors in various building constructions.
Distansrörens diameter och.materialtjocklek kan varieras beroende pä den belastning som sandwichelementet skall utsättas för och även inom ett enskilt sandwichelement kan dimensionerna hos dis- tansorganen varieras för att ge elementet en jämnstark eller jämnstyv uppbyggnad.The diameter and material thickness of the spacer tubes can be varied depending on the load to which the sandwich element is to be subjected and also within an individual sandwich element the dimensions of the spacer means can be varied to give the element an evenly strong or evenly rigid structure.
Uppfinningen beskrivs närmare nedan med hjälp av ett föredraget utföringsexempel under hänvisning till bifogade ritning, på vilken fig. 1 visar en schematisk perspektivvy snett ovanifrån av ett sandwichelement med två, på ett förutbestämt avstånd från varandra anordnade plåtar med ett distansorgan enligt uppfinningen, fig. 2 visar en annan vy av det i fig. 1 visade sandwich- elementet med ingående distansorgan, 515 sus _ fig. 3 visar en sidovy av ett i sandwichelementet ingående distansorgan enligt uppfinningen, fig. 4 visar distansorganet enligt fig. 3 i en vy ovanifrån, och fig. 5 visar en perspektivvy av ett sandwichelement försett med distansorgan enligt uppfinningen i en vy,snett under- ifrån.The invention is described in more detail below by means of a preferred embodiment with reference to the accompanying drawing, in which Fig. 1 shows a schematic perspective view obliquely from above of a sandwich element with two plates arranged at a predetermined distance from each other with a spacer according to the invention, Fig. 2 Fig. 3 shows a side view of a spacer according to the invention included in the sandwich element, Fig. 4 shows the spacer according to Fig. 3 in a top view, and Fig. 5 shows a perspective view of a sandwich element provided with spacers according to the invention in a view, obliquely from below.
Såsom framgår av ritningarna visar dessa ett sandwichelement 1 för bildande av t.ex. ett dörr-, golv- eller vâggelement 2, som i det visade, föredragna utföringsexemplet består av två, på ett förutbestâmt avstånd från varandra, via distansorgan 3 medelst pressvetsning fixerade plåtar 4, 5.As can be seen from the drawings, these show a sandwich element 1 for forming e.g. a door, floor or wall element 2, which in the preferred embodiment shown consists of two plates 4, 5 fixed by means of press welding, at a predetermined distance from each other.
Såsom distansorgan 3 mellan plåtarna 4, 5 används ett cylinder- format eller cylinderliknande rör 6, som deformerats i ett upp- repat mönster i form av intryckningar 7. Intryckningarna 7 är anordnade på ett förutbestâmt avstånd från varandra utmed rörets 6 längdriktning och dessa sträcker sig tvärs röret 6 i valbara vinklingar i och för bildande från rörets 6 mantelyta utskjutande vulster eller vårtor 8. Avståndet mellan intryckningarna 7 kan varieras från fall till fall men är mestadels beroende av aktu- ella belastningsfall. Vulsterna eller vårtorna 8 är avsedda att underlätta svetsningen och bildar kontaktpunkter vid en liten anliggnings- eller kontaktyta mot de angränsande plåtarna 4, 5.As a spacer 3 between the plates 4, 5, a cylindrical or cylindrical tube 6 is used, which is deformed in a repeated pattern in the form of indentations 7. The indentations 7 are arranged at a predetermined distance from each other along the longitudinal direction of the tube 6 and these extend across the tube 6 at selectable angles in order to form bulges or warts 8 projecting from the mantle surface of the tube 6. The distance between the indentations 7 can be varied from case to case but is mostly dependent on current load cases. The beads or warts 8 are intended to facilitate welding and form contact points at a small abutment or contact surface against the adjacent plates 4, 5.
I det visade exemplet år intryckningarna 7 belägna på ett förut- bestâmt avstånd från varandra utefter rörets 6 längdriktning och sträcker sig tvärs detta i rät vinkel. Intryckningarna 7 är en- ligt denna utföringsform gjorda på ett sådant sätt att de plattar till rörets 6 cylinderform, så att ett antal, på företrädesvis jämnt avstånd efter varandra belägna fickor 9 bildas och vilken grad av tillplattning motsvarar storleken på de bildade vulsterna eller vårtorna 8. snusa 515 308 n Rörets 6 godstjocklek och tillplattning för bildande av intryck- ningarna 7 är varierbar för bildande av en optimal pressvårta eller -vulst 8 i förhållande till den aktuella plàttjockleken i de plåtarna 4, 5 bildande täckskikten. För fixeringen av plåtarna 4, 5 vid. distansorganen. 3 används enligt uppfinningen före- trädesvis pressvetsning och distansorganen 3 är placerbara mellan plåtarna 4, 5 i olika mönster med inbördes varierande avstånd beroende på den beräknade belastning eller utböjning som sand- wichelementet är avsett att utsättas för. Vid formnings- operationen av sandwichelementet är distaansorganen tack vare uppfinningen även sammanpressbara pà ett kontrollerbart sätt.In the example shown, the indentations 7 are located at a predetermined distance from each other along the longitudinal direction of the tube 6 and extend across it at a right angle. According to this embodiment, the depressions 7 are made in such a way that they flatten into the cylindrical shape of the tube 6, so that a number of pockets 9, preferably evenly spaced one after the other, are formed and the degree of flattening corresponds to the size of the beads or warts 8 formed. snuff 515 308 n The wall thickness and flattening of the tube 6 to form the indentations 7 is variable to form an optimal press wart or bead 8 in relation to the actual plate thickness in the cover layers forming the plates 4, 5. For fixing the plates 4, 5 at. the spacers. 3 is preferably used according to the invention, press welding and the spacers 3 can be placed between the plates 4, 5 in different patterns with mutually varying distances depending on the calculated load or deflection to which the sandwich element is intended to be subjected. In the shaping operation of the sandwich element, the spacers are, thanks to the invention, also compressible in a controllable manner.
Distansorganen 3 kan ha en diameter och godstjocklek som står i relation till plåttjockleken och den belastning eller utböjning elementet är avsett att tåla. Sandwichelementets 1 sidokanter kan, såsom exempelvis framgår närmare av fig. 5, vara utformade med en not 10 som är avsedd att samverka och förbindas med från ett intilliggande element utskjutande spont.The spacers 3 may have a diameter and wall thickness which is in relation to the plate thickness and the load or deflection the element is intended to withstand. The side edges of the sandwich element 1 can, as can be seen in more detail in Fig. 5, be formed with a groove 10 which is intended to co-operate and be connected to a tongue projecting from an adjacent element.
Sandwichelementet 1 kan således uppvisa olika former. Det kan t.ex. vara helt plant med öppna sidor, helt plant med slutna sidor med. hjälp av t.ex. in- eller påmonterade U-profiler, formade med not och spont, sä att en skarvning kan göras när det ena elementet placeras i exempelvis 90° vinkel eller i andra vinklar mot det andra.The sandwich element 1 can thus have different shapes. It can e.g. be completely flat with open sides, completely flat with closed sides with. using e.g. mounted or mounted U-profiles, shaped with tongue and groove, so that a joint can be made when one element is placed at, for example, a 90 ° angle or at other angles to the other.
