Den foreliggende opfindelse angår en forstærkningsfiber for et støbeligt materiale, som for eksempel beton, hvilken fiber er fremstillet af jern ud fra et retliniet, trådformigt legeme og er ved hver ende forsynet med et hoved, hvor i det mindste én tværdimension er 5 større end diameteren for det trådformige legeme.The present invention relates to a reinforcing fiber for a castable material, such as concrete, which is made of iron from a straight, filamentous body and is provided at each end with a head at least one cross-sectional size greater than the diameter for the filamentous body.
Ved forstærkning af støbelige materialer med hydraulisk bindemiddel er teknikken til forstærkning af beton ved hjælp af metalliske fibre, som for eksempel korte trådformige elementer af jern, for tiden en almindelig fremgangsmåde; egenskaberne for betonen, der er forstær-10 ket ved hjælp af disse fibre, er for tiden velkendt og flere forskellige typer fiberprodukter, der er beregnet til disse vel specificerede anvendelser, er for tiden tilgængelige.In reinforcing castable materials with hydraulic binder, the technique of reinforcing concrete using metallic fibers, such as short iron filamentous elements, is presently a common method; the properties of the concrete reinforced by these fibers are presently well known and several different types of fiber products intended for these well specified applications are presently available.
De forskellige typer fibre er kendetegnet ved deres forstærkningseffekt på det sammensatte materiale, hvilken effekt er frembragt ved 15 deres geometriske og mekaniske egenskaber.The different types of fibers are characterized by their reinforcing effect on the composite material, which is produced by their geometric and mechanical properties.
Ideelt vil forstærkningen ved hjælp af fibre medføre en forøgelse af det sammensatte materiales brudenergi i forhold til det uarmerede materiales.Ideally, the reinforcement by means of fibers will increase the bridging energy of the composite material over that of the unarmed material.
Energi forøgel sen, der er nødvendig for brud, svarer til den energi, 20 som er nødvendig til forlængelse og brud af den fibrøse forstærkning.The energy increase needed for fracture corresponds to the energy needed to extend and break the fibrous reinforcement.
Denne forklaring af den fibrøse forstærknings optræden gør det let at forstå nødvendigheden af, at tilvejebringe en fuldkommen fast forbindelse mellem fibrene og det støbelige materiale.This explanation of the appearance of the fibrous reinforcement makes it easy to understand the necessity of providing a perfectly firm connection between the fibers and the moldable material.
Man kan karakterisere de forskellige typer fibre, der for tiden er 25 tilgængelige, og som er vist i medfølgende tegnings fig. 1-5.One can characterize the various types of fibers currently available and shown in the accompanying drawings. 1-5.
- Lange og rette fibre, således som vist i fig. 1.Long and straight fibers, as shown in FIG. First
- Kun adhæsionsspændingerne, der forekommer langs grænsefladen mellem fibre og form, kan frembringe en forankring af fibren i materialet.- Only the adhesive stresses that occur along the fiber-shape interface can provide an anchoring of the fiber to the material.
30 Det ses, at det er nødvendigt, at fibrens diameter er mindst 200 gange mindre end dens længde, for at kunne påvirke fibren med et træk til den når en trækspænding i umiddelbar nærhed af dens brudspænding; af praktiske fremstillingsårsager er det udelukket at anvende fibre, som har et sådant geometrisk særpræg.It is seen that it is necessary that the diameter of the fiber is at least 200 times smaller than its length in order to be able to influence the fiber with a tensile force until it reaches a tensile stress in the immediate vicinity of its tensile stress; For practical manufacturing reasons, the use of fibers which have such a geometrical distinctive character is excluded.
35 - Lange fibre der er forsynet med kroge ved deres ender.35 - Long fibers with hooks at their ends.
Tre forskellige kendte typer er vist i fig. 2. Krogenes tilstedeværelse ved enderne gør det muligt, at tilvejebringe fibrens vedhæftning i formen.Three different known types are shown in FIG. 2. The presence of the hooks at the ends makes it possible to provide the adhesion of the fiber in the mold.
Fibrens opførsel afhænger af krogenes holdekraft i formen.The behavior of the fiber depends on the holding power of the hooks in the mold.

Det er eksperimentelt konstateret, at uanset krogenes geometri (antal modstillede krumninger, rundingsradius) er den nødvendige energi til deres udretning altid mindre end brudenergien ved trækpåvirkning af fibren; det følger heraf, at fibrene, der er forsynet med kro-5 ge, ofte ikke bliver bragt i en tilstand i umiddelbar nærhed af deres brudstyrke i en revne i formen, men vil være løsnet ved udretning af krogene.It has been experimentally found that regardless of the geometry of the hooks (number of opposite curves, radius of radius), the energy required for their alignment is always less than the bridging energy of tensile action of the fiber; It follows that the fibers provided with hooks are often not brought into a state in the immediate vicinity of their tensile strength in a crack in the mold, but will be loosened by straightening the hooks.
Som konklusion erkendes det, at krogene ved enderne, selv om de i væsentlig grad forbedrer det sammensatte materiales fastholdelseskraft, 10 ikke er tilstrækkelige til at opnå den ideelle fastholdelseskraft.In conclusion, it is recognized that the hooks at the ends, although substantially improving the retention force of the composite, are not sufficient to achieve the ideal retaining force.
- Kendte fibre der er forsynet med sinusformede bølgeformer, som er fordelt regelmæssigt langs hele deres længde.- Known fibers having sinusoidal waveforms which are distributed regularly throughout their length.
I dette tilfælde er udretningsenergien atter meget mindre end fibrens brudenergi ved træk; antallet af bølgeformer langs en fiber vil 15 ikke kompensere for en krumningsradius, der er for stor til hver bølgeform.In this case, the straightening energy is again much less than the tensile energy of the fiber; the number of waveforms along a fiber will not compensate for a radius of curvature that is too large for each waveform.
Disse fibre er vist i fig. 3.These fibers are shown in FIG. Third
- Fibre, der er glatte og rette, og som langs deres længde omfatter udhamrede dele, der ligeledes kan være tilvejebragt ved deres ender.Fibers which are smooth and straight and which, along their length, comprise hammered parts which may also be provided at their ends.
20 Disse kendte fibre er vist i fig. 4.These known fibers are shown in FIG. 4th
I dette tilfælde er vedhæftningen begrænset, da de udhamrede deles kanter er for agressive for materialet.In this case, the adhesion is limited as the edges of the hammered parts are too aggressive for the material.
Således som det er konstateret eksperimentelt vil materialet faktisk kunne overskæres af de udhamrede dele som følge af den skadelige 25 løsgørelse, når fibren er underlagt en trækkraft - Ujævne fibre der er rette eller ikke rette.As has been found experimentally, the material may actually be cut by the hammered parts as a result of the detrimental detachment when the fiber is subjected to traction - Uneven fibers that are straight or not straight.
Disse kendte fibre er vist i fig. 5.These known fibers are shown in FIG. 5th
I dette tilfælde er ruheden og/eller krumningerne utilstrækkelige til at tilvejebringe en vedhæftning.In this case, the roughness and / or curvature are insufficient to provide an adhesion.
30 I engelsk patentskrift nr. 1.446.855 angives blandt andet fibre, hvis trådformige legemer er forsynet med bølgeformer, og hvis to ender hver er forsynet med et hoved, der enten er udhamret eller fortykket som et sømhoved men uden rotationssymmetri.30 English Patent No. 1,446,855 discloses, among other things, fibers whose filamentous bodies are provided with waveforms and whose two ends are each provided with a head which is either hammered or thickened as a nail head but without rotational symmetry.
Forstærkningsfibre, der omfatter et ret trådformigt legeme, og som 35 ved hver ende har et sfærisk hoved kendes desuden fra fransk patentskrift nr. 2.370.839 samt fra USA patentskrift nr. 3.684.474. Ingen af disse kendte fibre fungerer fuldt tilfredsstillende. Enten er forankringen utilstrækkelig eller også brækker fibren itu ved punktet for overgangen mellem et hoved og det trådformige legeme, eller også kan 3In addition, reinforcing fibers comprising a rather filamentous body and having at each end a spherical head are known from French Patent No. 2,370,839 and from U.S. Patent No. 3,684,474. None of these known fibers functions fully satisfactorily. Either the anchorage is inadequate or the fiber breaks at the point of transition between a head and the filamentous body, or 3
DK 152935BDK 152935B
selve det støbelige materiale skades.the moldable material itself is damaged.
Den velbegrundede sammenligning mellem forskellige aktuelt tilgængelige fibre hjælper til en bedre forståelse af det stillede problem: - Tilvejebringelse af en fiber, der vedhæfter fuldkommen til det 5 støbelige materiale, det vil sige som aldrig løsgør sig hverken på grund af selve fibren eller på grund af et brud i det støbelige materiale i nærheden af forankringsstedet.The well-reasoned comparison of various currently available fibers helps to better understand the problem posed: - Providing a fiber that adheres perfectly to the moldable material, that is, which never loosens either because of the fiber itself or because of a fracture of the moldable material near the anchorage site.
Med en sådan type fibre er det sammensatte materiales brudenergi den samme som for det uarmerede materiale forøget med den fibrøse for-10 stærknings brudenergi.With such a type of fiber, the bridging energy of the composite material is the same as that of the unarmed material increased by the bridging energy of the fibrous reinforcement.
Det er formålet med den foreliggende opfindelse at tilvejebringe en fiber af den type, som er angivet i indledningen til kravet, og som er beregnet til at forstærke et støbeligt materiale, .for eksempel beton, hvilken fiber aldrig løsner sig herfra hverken på grund af selve 15 fibren eller på grund af et brud i det støbelige materiale i umiddelbar nærhed af forankringen.It is the object of the present invention to provide a fiber of the type set forth in the preamble of the claim which is intended to reinforce a moldable material, for example concrete, which fiber never loosens from it either because of the 15 or due to a break in the moldable material in the immediate vicinity of the anchorage.
Med henblik på opfyldelse af dette formål er forstærkningsfibren ifølge den foreliggende opfindelse særpræget ved, at i det mindste den del af hovedet, som er i kontakt med det trådformige legeme, har form 20 som et omdrejningslegeme, der er afgrænset af en frembringerkurve, hvor vinklen mellem tangenten i hvert af frembringerkurvens punkter og aksen for det trådformige legeme har en værdi mellem 0° og 60°, og at tangentens skæring med aksen altid befinder sig i selve volumenet for hovedets indre del.For the purpose of this purpose, the reinforcing fiber of the present invention is characterized in that at least the portion of the head which is in contact with the filamentous body has shape 20 as a rotary body defined by a producing curve, the angle of which is between the tangent of each point of the generating curve and the axis of the filamentous body has a value between 0 ° and 60 °, and that the tangent of the tangent with the axis is always in the volume of the inner part of the head itself.
25 Med en således fremstillet forstærkningsfiber vil der aldrig opstå en løsgørelse af forstærkningsfibren fra materialet, og forstærkningsfibren vil heller ikke forårsage et brud i materialet i en umiddelbar nærhed af dens forankring i materialet, idet den indre del af hovedet er udformet som et omdrejningslegeme med en "jævn" overgang, hvilket 30 sikre fibrens vedhæftning til materialet, samtidig med at den ikke fremkalder noget brud i materialet, hvilket ville kunne fremkaldes af skarpe overgange, som vil kunne overskære materialet, når fibren er underlagt en trækkraft.With such a reinforcing fiber, the reinforcing fiber will never be detached from the material, nor will the reinforcing fiber cause a break in the material in the immediate vicinity of its anchorage in the material, the inner part of the head being designed as a rotating body with a "smooth" transition, which ensures the adhesion of the fiber to the material while not causing any rupture of the material, which could be caused by sharp transitions which would cut the material when the fiber is subject to a traction.
Størrelsen for vinklen mellem tangenten i et hvert punkt på frem-35 bringerkurven og aksen for det trådformige legeme vil for at opnå den ideelle opførsel afhænge af egenskaberne ved det materiale, som udgør fibren.The size of the angle between the tangent at each point of the producing curve and the axis of the filamentous body will depend on the properties of the material constituting the fiber to achieve the ideal behavior.
For eksempel vil jern, for mindre mekanisk styrke, fordre større vinkler for hovedet og vil for større mekanisk styrke fordre mindre 4For example, for less mechanical strength, iron will require larger angles of the head and for greater mechanical strength will require less 4

De trådformige fibre, som beskrives herefter, kan fremstilles ved anvendelse af flere fremgangsmåder.The filamentous fibers described hereinafter can be made using several methods.
Opfindelsen vil herefter blive beskrevet mere detaljeret under 5 henvisning til den medfølgende tegning, hvor fig. 1-5 viser billeder af fibre med kendte udformninger, fig. 6A og 6B viser skematiske billeder af et apparat, der anvendes ved fremstilling af fibre ifølge opfindelsen, fig. 7 et billede af detaljen X i fig. 6A, 10 fig. 8 et billede set forfra af cylinderparret i fig. 6A, fig. 9 et snitbillede gennem detaljen Y i fig. 6B, og fig. 10 et perspektivisk billede af nogle udførelsesformer for fibre ifølge opfindelsen.The invention will then be described in more detail with reference to the accompanying drawing, in which: FIG. 1-5 show images of fibers of known designs; FIG. 6A and 6B are schematic views of an apparatus used in the manufacture of fibers according to the invention; 7 is a view of the detail X of FIG. 6A, 10 FIG. 8 is a front view of the cylinder pair of FIG. 6A, FIG. 9 is a sectional view through the detail Y of FIG. 6B, and FIG. 10 is a perspective view of some embodiments of fibers of the invention.
I de forskellige figurer vil samme henvisningsbetegnelser betegne 15 identiske elementer.In the various figures, the same reference numerals will denote 15 identical elements.
Således som vist i fig. 6A trækkes den opviklede tråd, der generelt er betegnet med henvisningsbetegnelsen 1, mod et valseapparat 2, der består af et par valsecylindre med spor, der regelmæssigt over deres længde, og som er forsynet med indsnitsmatricer for fibrenes 20 hoveder, for hvilke figurerne 7 og 8 viser et eksempel på en måde til at reducere tråddiameteren af grundmaterialet til diameteren for fibrens trådformige legeme med undtagelse af stillingerne for disse fibres hoveder.Thus, as shown in FIG. 6A, the wound wire, generally designated by reference numeral 1, is pulled toward a rolling apparatus 2 consisting of a pair of roll cylinders with grooves of regular length and provided with incision matrices for the heads of the fibers 20, for which Figures 7 and Figure 8 shows an example of a way to reduce the thread diameter of the base material to the diameter of the filamentous body of the fiber except for the positions of the heads of these fibers.
Dette valseapparat 2 tilvejebringer en tråd med en diameter der er 25 mindre end udgangsdiameteren og som med regelmæssige mellemrum er forsynet méd forstørrelser. En overklipningsmekanisme 4 adskiller tråden, for således at opnå halvdele af hver forstørrelse, for således at danne fibrene, der er forsynet med hoveder.This rolling apparatus 2 provides a wire having a diameter 25 smaller than the output diameter and which is provided with enlargements at regular intervals. An over-cutting mechanism 4 separates the thread, so as to obtain halves of each magnification, so as to form the fibers provided with heads.
Således som vist i fig. 6B trækkes den opviklede tråd, der gene-30 relt er betegnet med henvisningsbetegnelsen 1, mod et overklipningsapparat, der frembringer rette trådformige elementers 6, der har en kort konstant længde og som kan gribes individuelt, og fastklemmes, således som vist i fig. 9, ved deres ender mellem to matricer, og de ønskede hoveder frembringes ved hjælp af prægestempler i deres nøjagtige form.Thus, as shown in FIG. 6B, the wound wire, generally designated by reference numeral 1, is pulled toward a clipping apparatus which produces straight filamentary elements 6 having a short constant length and which can be individually gripped and clamped, as shown in FIG. 9, at their ends between two matrices, and the desired heads are produced by stamping in their exact form.
35 Således som det fremgår af fig. 10 omfatter fibren 5 et trådfor- migt legeme 6 og ved hver ende af denne et hoved 8 med en større diameter. I det mindste den indre del af hovedet, det vil sige af dette, som er i kontakt med det trådformige legeme 6, har form som et omdrejningslegeme, som er defineret af en frembringerkurve. Tangenten i et-35 As shown in FIG. 10, the fiber 5 comprises a filamentous body 6 and at each end thereof a head 8 having a larger diameter. At least the inner portion of the head, that is, of this, which is in contact with the filamentous body 6, has the shape of a rotary body defined by a generating curve. The key in one-
DK 152935BDK 152935B
s hvert punkt af denne frembringerkurve danner sammen med længdeaksen for det trådformige legeme 6 en vinkel <*, hvis værdi er mellem 0° og 60°. Tangentens skæring med aksen vil altid befinde sig i selve volumenet for nævnte indre del af hovedet.s each point of this generating curve together with the longitudinal axis of the filamentous body 6 forms an angle <* whose value is between 0 ° and 60 °. The intersection of the key with the axis will always be in the actual volume of said inner part of the head.
5 Fig. 10 viser nogle mulige værdier for or som funktion af kontakt punktet mellem tangenten og frembringerkurven.FIG. 10 shows some possible values for or as a function of the contact point between the tangent and the generating curve.
Ifølge en fremgangsmåde til fremstilling af fibre ifølge opfindelsen vil et trådformigt element med en ubestemt længde og en diameter, der er identisk med den største tværdimension for hovedet, ved passage 10 gennem et par med riller forsynede valsecylindre, hvis riller er forsynet med indbyrdes adskilte indsnit, faktisk undergå en diameterreduktion over hele længden med undtagelse af hovederne, der dannes ved stillingerne for indsnittene, der er udskåret langs valsecylindrenes riller.According to a method of making fibers according to the invention, a filamentary element of an indefinite length and diameter identical to the largest cross-section of the head will pass, through passage 10, through a pair of grooved roller cylinders whose grooves are provided with spaced apart incisions. , in fact, undergo a diameter reduction over the entire length, with the exception of the heads formed at the positions of the incisions cut along the grooves of the roller cylinders.
15 Det følgende trin i denne fremgangsmåde består i en regelmæssig udskæring af det kontinuert udvalsede trådformige element på en måde så der dannes fibre med en præcis længde, og som er forsynet med et hoved ved hver ende.The next step of this method consists in a regular cutting of the continuously rolled filamentary element in a manner to form fibers of precise length and provided with a head at each end.
En anden fremgangsmåde udføres gennem prægning af en knebel på 20 hver ende af et trådformigt element, der er tilvejebragt uden hoved, og som har en diameter, der er identisk med den for fibrens legeme, hver af hvilke ender fastholdes under prægningen ved hjælp af en matrice, for således at opnå et hoved med ønsket form.Another method is carried out by embossing a girdle at each end of a thread-shaped element provided without a head having a diameter identical to that of the body of the fiber, each end of which is retained during embossing by means of a die, so as to obtain a head of desired shape.
En tredje fremgangsmåde udføres ved dannelse af en dråbeform ved 25 enderne af det trådformige element ved en temperatur i nærheden af grundmaterialets smeltepunkt. Efter denne formgivning kan der følge en hærdning for at forbedre fibrens mekaniske egenskaber.A third process is performed by forming a droplet shape at the ends of the filamentary element at a temperature close to the melting point of the base material. Following this shaping, curing may be followed to improve the mechanical properties of the fiber.
