Den foreliggende opfindelse angår en fremgangsmåde for tilvejebringelse af en armeret murværksbjælke i liggefugen hos murskifte ved at indmure langsgående armering samt en anordning til udøvelse af fremgangsmå-5 den.The present invention relates to a method of providing a reinforced masonry beam in the bed joint of a wall switch by wall-length reinforcement and a device for carrying out the method.

Ved muring af bjælker af f.eks. teglsten over større åbninger såsom vinduesåbninger og lignende åbninger med stor spændvidde er det tidligere kendt at tilvejebringe langsgående armering ved murstensskifter ved 10 indlægning af trækarmering i liggefugerne. Ved den pågældende kendte fremgangsmåde frembringes imidlertid en konstruktion, i hvilken der let opstår horisontale revner imellem fugemasse og mursten, hvorved det underste murstensskrifte almindeligvis vil falde ned. En medvir-15 kende årsag hertil kan være, at armeringsstængerne bliver svækket på grund af rustangreb.When walling beams of e.g. bricks over larger openings such as window openings and similar openings with a wide span, it is previously known to provide longitudinal reinforcement by brick switching by inserting wood reinforcement into the reclining joints. However, by the known method in question, a structure is produced in which horizontal cracks between grout and brick are easily formed, whereby the lower brick writing will generally fall. One contributing reason for this may be that the reinforcing bars are weakened by rust attacks.

Det er endvidere kendt at lade det underste skifte udgøre af et præfabrikeret spændarmeret teglstensskifte.Furthermore, it is known to let the lower switch constitute a prefabricated clamped brick replacement.

Denne fremgangsmåde har dog den ulempe, at et sådant 20 teglstensskifte ikke kan arbejde sammen med ovenover liggende mursten.However, this method has the disadvantage that such a change of brick cannot work with superimposed bricks.

Opfindelsen har til formål at angive en fremgangsmåde til fremstilling af murstensbjælker, ved hvis anvendelse de anførte ulemper mindskes.The invention has for its object to provide a method for the manufacture of brick beams, the use of which alleviates the disadvantages mentioned.

25 Dette opnås ved hjælp af fremgangsmåden ifølge opfindelsen, som er ejendommelig ved, at det for armeringen anvendes såvel langsgående trådformig armering, som indmures i liggefugen hos murskifte lagt ind i fugemassen og tværgående trådformig armering, som rager ud 30 fra den langsgående trådformige armerings plan, og som anvendes for armering lagt ind i fugemassen i murskif-tets lodfuger.This is achieved by the method according to the invention, which is characterized in that for the reinforcement, both longitudinal filamentous reinforcement, which is walled into the joint of the wall joint inserted into the joint and transverse filamentous reinforcement projecting from the longitudinal filamentary reinforcement plane, are used. , and used for reinforcement inserted into the grout in the wall joint solder joints.

Opfindelsen har yderligere til formål at angive en anordning til udøvelse af fremgangsmåden ifølge opfin-35 delsen, hvilken anordning ifølge krav 6 er ejendommelig ved, at en armering dannes af et separat stykke, som består af en langsgående trådformigt armeringselement, 2 fra hvilket flere tværgående trådformige armeringselementer rager ud i højderetningen.The invention further aims to provide a device for carrying out the method according to the invention, which device according to claim 6 is characterized in that a reinforcement is formed of a separate piece consisting of a longitudinal filamentous reinforcing element, 2 from which several transverse threaded reinforcing elements protrude in the height direction.

Opfindelsen forklares i det følgende nærmere under henvisning til tegningen, hvor 5 fig. 1 er et skematisk perspektivbillede af en teglstensbjælke med tilhørende armeringsindretning ifølge opfindelsen, fig. 2 er et sidebillede af en teglstensbjælke, som 10 strækker sig over en vinduesåbning, og fig. 3 er et perspektivbillede af en armeringsindretning ifølge opfindelsen.BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be explained in more detail with reference to the accompanying drawings, in which: FIG. 1 is a schematic perspective view of a brick beam with associated reinforcing device according to the invention; FIG. 2 is a side view of a brick beam 10 extending over a window opening; and FIG. 3 is a perspective view of a reinforcing device according to the invention.

Der tilsigtes med opfindelsen at fremstille en 15 armeret murværksbjælke, som er velegnet til at anbringes over vindues- og portalåbninger og lignende åbninger, men opfindelsen egner sig tillige til at finde anvendelse ved fremstilling af murværksbjælker, som kan anvendes ved opbygning af armerede teglstensvægge eller murblok-20 vægge, der skal kunne modstå -såvel sidetryk som lodrette belastninger.It is an object of the invention to provide a reinforced masonry beam which is suitable for mounting over window and portal openings and similar openings, but the invention is also suitable for use in the manufacture of masonry beams which can be used in the construction of reinforced brick walls or masonry blocks. -20 walls to withstand both side pressure and vertical loads.

En anordning 1, som egner sig til at anvendes ved fremstilling af en armeret murværksbjælke 2 ifølge opfindelsen, indbefatter en langsgående armering 3 med et 25 antal tværgående armeringsdele 4. Indretningen 1 kan hensigtsmæssigt fremstilles af eksempelvis trådformede stænger af varmforzinket eller rustfrit stål. Den langsgående armering 3 dannes i den viste udførelse af to parallelt med hinanden løbende separate stænger, men kan 30 naturligvis omfatte et andet antal stangformede dele med en anden udstrækning end den på tegningen viste. Tværar-meringerne 4 dannes af vinkelbukkede og/eller på anden måde tildannede tråde, der ved deres respektive frie ender 4A, 4B er fast forbundne, eksempelvis ved svejs-35 ning med hver sin langsgående stang 3 i armeringen.A device 1 suitable for use in the manufacture of a reinforced masonry beam 2 according to the invention includes a longitudinal reinforcement 3 having a plurality of transverse reinforcing members 4. The device 1 may conveniently be made of, for example, hot-dip galvanized or stainless steel wire rods. The longitudinal reinforcement 3 is formed in the illustrated embodiment of two parallel bars running parallel to each other, but can of course comprise a different number of rod-shaped parts of a different size than that shown in the drawing. The cross reinforcements 4 are formed by angularly bent and / or otherwise formed wires which are firmly connected at their respective free ends 4A, 4B, for example by welding each with its longitudinal rod 3 in the reinforcement.

Afstanden L mellem to ved siden af hinanden og på samme side af den langsgående armering 3 udragende tværgående 3The distance L between two adjacent to each other and on the same side of the longitudinal reinforcement 3 extending transversely 3

armeringstråde 4 svarer i hovedsagen til længden af en teglsten 5 eller anden egnet mursten, som benyttes ved opbygningen af en murværksbjælke 2 ifølge opfindelsen.reinforcing wires 4 correspond substantially to the length of a brick 5 or other suitable brick used in the construction of a masonry beam 2 according to the invention.

Et antal fortrinsvis U-formede bindernåle 6 er fast 5 og/eller løst forbundne med den langsgående armering 3, eksempelvis som vist i fig. 3.A number of preferably U-shaped tie pins 6 are fixedly 5 and / or loosely connected to the longitudinal reinforcement 3, for example as shown in FIG. Third

Fremstilling af en murværksbjælke 2 i overensstemmelse med opfindelsen finder sted på følgende måde: Ved hjælp af enkeltsten 5 og mørtel 7 eller anden fugemasse, 10 som påføres stenenes 5 endeflader 5A fremstilles først et "underste" murstensskifte 2 over eksempelvis en vinduesåbning 8. På det nævnte skifte 2 udlægges en armeringsindretning 1, således at den langsgående armering 3 hviler på oversiderne 5B af stenene 5. I de netop danne-15 de og endnu ikke afbundne lodfuger 7 i murskiftet 2 nedstikkes de omtalte bindenåle 6, hvorved opnås, at armeringsindretningen l og skiftet 2 vil blive bragt til at samvirke, når mørtelen 7 er afbundet.The manufacture of a masonry beam 2 in accordance with the invention takes place as follows: By means of single stone 5 and mortar 7 or other grout 10 applied to the end faces 5A of the stones 5, a "lower" brick switch 2 is first prepared over, for example, a window opening 8. said shift 2, a reinforcing device 1 is laid out so that the longitudinal reinforcement 3 rests on the upper sides 5B of the stones 5. In the newly formed and not yet tied solder joints 7 in the wall change 2, the said connecting pins 6 are lowered, which results in the reinforcing device 1 and the shift 2 will cooperate when the mortar 7 is unbound.

I mellemrummene 9, som sideværts begrænses af tvær-20 armeringer 4 og nedad af den langsgående armering 3, placeres mursten 5, som fuges sammen med skiftet 2 ved hjælp af en med mørtel frembragt langfuge 10 og indbyrdes ved hjælp af lodfuger 7 til dannelse af et øvre skifte li.In the spaces 9, which are laterally limited by cross-reinforcements 4 and downwards by the longitudinal reinforcement 3, are placed bricks 5, which are joined together with the shift 2 by means of a mortar produced long joint 10 and mutually by means of solder joints 7 to form an upper shift li.

25 Armeringsindretningen 1 er således indlejret i fugerne 7, 10, hvilket indebærer, at den frembragte bjælke 12 kan belastes, uden at der herved opstår revnedannelser.The reinforcing device 1 is thus embedded in the joints 7, 10, which means that the generated beam 12 can be loaded without causing cracking.

Det vil endog være muligt at presse tværarmeringen 30 4 ned i mørtelen i lodfugen 7 ovenfra.It will even be possible to push the cross reinforcement 30 4 into the mortar in the plumbing 7 from above.

Ved anvendelse af opfindelsen opnås flere væsentlige fordele, idet armeret murværk herigennem kan fremstilles på en sådan måde, at en dannet blok holdes sammen i to retninger. Man kan således nu fremstille 35 murværksbjælker, der fungerer på lignende måde som betonbjælker, idet armeringsindretningen 1 udvirker såvel vertikal som horisontal armering i bjælken 12.By employing the invention, several significant advantages are obtained, in that reinforced masonry can thereby be manufactured in such a way that a formed block is held together in two directions. Thus, 35 masonry beams can now be produced which function in a similar manner to concrete beams, with the reinforcing device 1 acting both vertically and horizontally in the beam 12.
