Den foreliggende opfindelse angår en forskallingssten med en ydervæg, en indervæg med et derimellem liggende hulrum til betonopfyldning, med to endevægge, som er forsynet med udsparinger, og med et isoleringsindlæg, som strækker sig 5 henover indersiden af ydervæggen.The present invention relates to a formwork stone with an outer wall, an inner wall with an intermediate cavity for concrete filling, with two end walls provided with recesses and with an insulating insert extending over the inside of the outer wall.
For at. spare omkostninger anvendes i stigende omfang i husbygning forskallingssten, især til kældre. Det er dog også muligt at opbygge alle mure i et hus med forskallingssten. Forskallingssten har den fordel, at de også lader sig anvende 10 af folk uden uddannelse i byggefagene. Sædvanligvis opstilles kun det første skifte af sten i mørtel, medens resten stilles tørt op som byggeklodser. Til dette formål er sådanne forskallingssten i almindelighed forholdsvis nøjagtige i målene, til hvilke de er fræset og forsynet med fjer og not. Efter 15 at forskallingsstenene er opstillet i etagehøjde, udfyldes deres hulrum med beton. På denne måde opnås der en meget stabil væg på enkel måde.To. Saving costs are increasingly used in house building formwork bricks, especially for basements. However, it is also possible to build all the walls in a house with formwork bricks. Formwork stones have the advantage that they can also be used by 10 of people without education in the construction industry. Usually only the first change of stone is set in mortar, while the rest is set up dry as building blocks. For this purpose, such formwork bricks are generally relatively accurate in the dimensions to which they are milled and provided with feathers and groove. After the formwork stones are erected at floor height, their cavities are filled with concrete. In this way, a very stable wall is obtained in a simple manner.
Sådanne forskallingssten har dog kun en ringe varmeisoleringsevne. Af denne grund kendes der allerede forskallings-20 stene med et isoleringsindlæg. Til dette formål er væggene på forskallingsstenenes hulrum fuldstændig beklædt med isoleringsindlægget. Herved opnås en relativt god varmeisolering, men det er en ulempe, at der næsten ikke kan finde nogen varmeoplagring sted i væggen. Den ifyldte beton ville her 25 med en art kakkelovnseffekt være et meget godt varmelager, men da den også på indersiden er omgivet af styropor, kan den ikke komme i betragtning til dette formål. Endvidere er det en ulempe, at der kun i ringe grad kan ske en kondensation af fugtighed eller en fugtighedstransport gennem 30 stenen. Herved vil der gå meget lang tid ved et færdigt hus inden den såkaldte byggefugtighed er udtørret, og der er risiko for, at på væggen anbragte plader kan falde ned.However, such formwork stones have only a poor thermal insulation ability. For this reason, formwork bricks with an insulating insert are already known. For this purpose, the walls of the formwork stone cavity are completely lined with the insulating insert. This provides a relatively good thermal insulation, but it is a disadvantage that almost no heat storage can take place in the wall. The filled concrete would here with a kind of stove effect be a very good heat storage, but since it is also surrounded by styrofoam on the inside, it can not be considered for this purpose. Furthermore, it is a disadvantage that only a condensation of moisture or a moisture transport can occur through the rock. This will take a very long time at a finished house before the so-called building moisture has dried up, and there is a risk that slabs placed on the wall may fall.
Den i hulrummet fyldte beton, som på alle sider er omgivet af isoleringsindlægget, er ifølge sagens natur meget fugtig, 35 og denne fugtighed kan kun meget langsomt trænge udefter.The concrete filled in the cavity, which is surrounded on all sides by the insulating insert, is naturally very moist, 35 and this moisture can only very slowly penetrate the outside.
Men også senere lider indeklimaet under sådanne sten, idet det i rummet til stadighed forekommende damptryk kun i ringe grad kan bortledes gennem en sådan væg.But even later, the indoor climate suffers from such stones, as the vapor pressure that occurs in the room can only be dissipated to a small extent through such a wall.

Den foreliggende opfindelse har til opgave at tilvejebringe en forskallingssten af den indledningsvis nævnte art, som samtidig med at den er enkel at håndtere har gode varme- og lydisoleringsegenskaber uden fugtighedsproblemer.The object of the present invention is to provide a formwork stone of the kind mentioned at the outset which, while being easy to handle, has good heat and sound insulation properties without moisture problems.
5 Denne opgave løses ifølge opfindelsen ved, at isole ringsindlægget forløber langs indersiden af endevæggene langs udsparingerne henover disse og at udsparingernes endekanter omfattes af en forlængelse af isoleringsindlægget.This problem is solved according to the invention in that the insulating insert extends along the inside of the end walls along the recesses thereof and that the end edges of the recesses are covered by an extension of the insulating insert.
Ifølge opfindelsen anbringes isoleringsindlæggene 10 nu således, at der opnås en god varme- og lydisolering, idet der yderligere er sørget for en tilstrækkelig fugtigheds-transport gennem forskallingsstenen. Således befinder der sig fx mellem indervæggen af forskallingsstenen og hulrummet, i hvilket der senere ifyldes beton, ikke noget isolerings-15 indlæg. Dette betyder, at der opnås en kakkelovnseffekt, for varmen i det indvendige rum kan oplagres i betonen.According to the invention, the insulating inserts 10 are now arranged so as to obtain a good heat and sound insulation, while further providing adequate moisture transport through the formwork stone. Thus, for example, there is no insulating insert between the inner wall of the formwork stone and the cavity in which concrete is later filled. This means that a stove effect is obtained, because the heat in the interior space can be stored in the concrete.
Samtidig sørges der dog ved hjælp af de ved de to endevægge og på indersiden af ydervæggen anbragte isoleringsindlæg for, at varmen ikke kan transporteres udefter. Over udspa-20 ringerne står forskallingsstenene i en række i forbindelse med hinanden gennem betonfyldningen, hvorved der opnås en meget stabil forbindelse. Fugtighed kan føres bort via den del af endevæggene, som ikke er afbrudt ved hjælp af udsparingen på tværs af forskallingsstenen.At the same time, however, insulation inserts placed at the two end walls and on the inside of the outer wall prevent the heat from being transported outside. Above the recesses, the formwork stones are connected in a row through each other through the concrete filling, thus obtaining a very stable connection. Moisture can be carried away through the part of the end walls which is not interrupted by the recess across the formwork stone.
25 Ifølge en videre udformning kan udsparingen have en tunnelform, hvis endekanter er omfattet af isoleringsindlæg. Ved hjælp af denne udformning i forbindelse med beklædningen af endekanterne med isoleringsindlæggene forbedres isoleringsvirkningen.According to a further embodiment, the recess may have a tunnel shape, the end edges of which are covered by insulating inserts. By means of this design in connection with the lining of the end edges with the insulating inserts, the insulating effect is improved.
30 Endvidere kan tykkelsen af isoleringsindlæggene være tilspidset på indersiden af endevæggene i retning mod indervæggen .Further, the thickness of the insulating inserts may be tapered on the inside of the end walls towards the inner wall.
Denne udformning er i praksis mulig uden reduktion af varmeisoleringen. Samtidig skaffes der dog mere rum til 35 betonfyldningen og dermed opnås en højere statisk belastbar-hed af et derved fremstillet murværk.In practice, this design is possible without reducing the thermal insulation. At the same time, however, more space is provided for the concrete filling and thus a higher static load is achieved by a masonry thus produced.
En meget fordelagtig udformning består i, at beggeA very advantageous design consists of both
DK 163314 BDK 163314 B
3 endevægge yderligere er forsynet med en parallelt med endevæggenes yderside forløbende tværslids.3 end walls are further provided with a transverse slit extending parallel to the outer wall of the end walls.
De til fugtighedstransport beregnede endevægsdele opnår ved disse forholdsregler en bedre varmeisolering.The end wall parts intended for moisture transport, by these measures, achieve better thermal insulation.
5 Yderligere opnås der ved tværslidserne, at der ikke forelig ger et kraftigt betontværsnit, hvilket ligeledes medfører en forbedring af isoleringsegenskaberne.Further, at the cross slits, there is no strong concrete cross-section, which also improves the insulation properties.
I almindelighed vil man vælge bredden af slidserne og disses længde så stor som det forsvarligt. Forudsætningen 10 er, at der opnås en tilstrækkelig stabilitet af endevæggen.In general, one will choose the width of the slots and the length of them as large as it is reasonable. The premise 10 is that sufficient stability of the end wall is achieved.
En ligeledes meget fordelagtig udformning i henhold til opfindelsen består i, at de to endeflader ved deres bort fra udsparingerne vendte oversider har en parallelt med endevæggen forløbende isoleringsnot, ind i hvilken der 15 er anbragt en forlængelse af isoleringsindlægget.A very advantageous embodiment according to the invention also consists in the fact that the two end faces at their upper sides facing away from the recesses have an insulation groove extending parallel to the end wall into which an extension of the insulation insert is arranged.
På denne måde opnås det, at der ved oplægning af forskallingsstenen i mørtel ikke umiddelbart opnås kontakt mellem mørtelen og betonen, respektive endevæggen af forskallingsstenen. Ved hjælp af det i isoleringsnoten placerede 20 isoleringsindlæg undgås der på denne måde en direkte kontakt.In this way, it is achieved that when laying the formwork stone in mortar, contact between the mortar and concrete, or the end wall of the formwork stone, is not immediately achieved. By means of the 20 insulating inserts placed in the insulation note, direct contact is thus avoided.
På grund af disse forholdsregler forbedres varmeisoleringsevnen af forskallings stenen yderligere.Due to these precautions, the thermal insulation ability of the formwork stone is further improved.
Når forskallings stenen består af porebeton og eventuelt den til ifyldning beregnede beton er en letbeton, forbedres 25 isoleringsegenskaberne i endnu højere grad.When the formwork stone consists of pore concrete and, optionally, the concrete intended for filling is a lightweight concrete, the insulation properties are improved even more.
Isoleringsindlægget kan være udformet ud i ét, idet det efter fremstilling af forskallingsdelen indsættes på tilsvarende måde. For at opnå en lettere montage, især når endekanterne af udsparingen og isoleringsnoten er forsynet 30 med et isoleringsindlæg, vil man i almindelighed udforme isoleringsindlægget i to dele, idet delingsfugen i form af en trinafsats anbringes tilnærmelsesvis på midten af stenen til undgåelse af en afbrydelse i isoleringen.The insulating insert may be formed in one piece, after it has been manufactured in the formwork, in a corresponding manner. For easier assembly, especially when the end edges of the recess and insulating groove are provided with an insulating insert, the insulating insert will generally be formed in two parts, with the splitting joint, in the form of a step ledge, being placed approximately on the center of the stone to avoid a break in the insulation. the insulation.
I henhold til en meget fordelagtig udformning for 35 forskallingsstenen er ydervæggen og eventuelt også den indvendige væg forsynet med en afstivningsribbe på indersiden. Herved kan afstivningsribben være udformet således, at den er gennemløbende i vertikal retning og befinder sig i området ved stenens midterplan.According to a very advantageous design for the formwork stone, the outer wall and possibly also the inner wall is provided with a stiffening rib on the inside. Hereby, the stiffening rib may be designed so that it is continuous in a vertical direction and is in the region at the median plane of the stone.

Selvfølgelig er der inden for rammerne af opfindelsen også mulighed for flere sådanne ved siden af hinanden placerede afstivningsribber. Dette afhænger af længden og typen af stenen. Det samme gælder for retningsforløbet af afstiv- 5 ningsribberne.- Ved hjælp af sådanne afstivningsribber kan forskallingsdelen gøres væsentligt mere stabil over for de optrædende tryk og b'øjningspåvirkninger. Dette gælder fx ved præfabrikering af vægge, hvor det indvendige rum af forskallingsdelen endnu er åbent. Ved hjælp af afstiv- 10 ningsribberne formindskes risikoen for brud. Forstærkningsribberne er dog også fordelagtige ved ifyldning af betonen i det fri indvendige rum af forskallingsstenene. Herunder optræder der nemlig tilsvarende høje tryk, hvorved forstærkningsribberne virker stabiliserende.Of course, within the scope of the invention, there is also the possibility of several such stiffening ribs placed side by side. This depends on the length and type of stone. The same is true of the direction of the stiffening ribs. With the help of such stiffening ribs, the formwork part can be made substantially more stable against the pressure and bending stresses that occur. This applies, for example, to prefabrication of walls where the interior space of the formwork part is still open. Using the stiffening ribs reduces the risk of breakage. However, the reinforcing ribs are also advantageous in loading the concrete into the free interior space of the formwork bricks. This is because there are correspondingly high pressures, which makes the reinforcing ribs stabilizing.
15 Men også efter fremstilling af bygningen er forstærk ningsribberne på ydervæggen en fordel. Udsættes en sådan væg nemlig for høje solindstrålinger, fx på en sydvendt væg, kan den udvendige væg på grund af det bagved liggende isoleringsindlæg blive opvarmet meget. På grund af forstærk- 20 ningsribberne reduceres risikoen for at der optræder revner 1 pudslaget væsentligt.15 But even after the construction of the building, the reinforcing ribs on the outer wall are an advantage. If such a wall is exposed to high solar radiation, for example on a south-facing wall, the exterior wall can be greatly heated due to the insulation lining behind. Due to the reinforcing ribs, the risk of cracking 1 is significantly reduced.
I det følgende skal opfindelsen beskrives nærmere ved hjælp af et på tegningen vist udførelseseksempel.In the following, the invention will be described in more detail by means of an exemplary embodiment shown in the drawing.
På tegningen viser: 25 Fig. 1 en forskallingssten ifølge opfindelsen set ovenfra, idet den højre halvdel viser et horisontalsnit langs linien I-I ifølge fig. 2, fig. 2 en forskallingssten set fra enden, fig. 3 en perspektivisk afbildning af en forskallings- 30 sten, fig. 4 flere sammenstillede forskallingssten, og fig. 5 en forskallingssten med forstærkningsribber set ovenfra.In the drawing: FIG. 1 is a plan view of a formwork stone according to the invention, the right half showing a horizontal section along the line I-I according to FIG. 2, FIG. 2 is a side view of a formwork stone; FIG. 3 is a perspective view of a formwork stone; FIG. 4 shows several assembled formwork bricks, and FIG. 5 a formwork stone with reinforcing ribs seen from above.
Forskallingsstenen har en ydervæg 1, en indervæg 35 2 og endevægge 3 og 4. Disse vægge omslutter derved et hulrum 5, i hvilket der efter oplægning af forskallingsstenen kan ifyldes beton ovenfra. Ved hjælp af udsparinger 6 medThe formwork stone has an outer wall 1, an inner wall 35 2 and end walls 3 and 4. These walls thereby enclose a cavity 5, in which, after laying the formwork stone, concrete can be filled from above. Using recesses 6 with
DK 163314 BDK 163314 B
5 tunnelform i endevæggene 3 og 4 står hulrummene 5 på ved siden af hinanden opstillede forskallingssten i forbindelse med hinanden.5 tunnel form in the end walls 3 and 4, the cavities 5 on adjacent formwork bricks are interconnected.
I endevæggene 3 og 4 er der diagonalt over for hinanden 5 anbragte forbindelsesorganer i form af noter 7 og fjer 8, ved hvilke en nøjagtig og ubrudt opstilling af forskallingsstenene efter hinanden er mulig. I de to endevægge 3 og 4 er der endvidere indrettet tværslidser 9, som kan være gennemløbende i vertikal retning. Selvfølgelig kan 10 de også være lukket mod en yderside af forskallingsdelen.In the end walls 3 and 4, connecting members are arranged diagonally opposite each other 5 in the form of grooves 7 and feathers 8, whereby an accurate and unbroken arrangement of the formwork bricks is possible one after another. Furthermore, in the two end walls 3 and 4, transverse slots 9 are provided, which may be continuous in vertical direction. Of course, they may also be closed against an outside of the formwork portion.
For at opnå den størst mulige længde af tværslidserne 9 er disse anbragt forsat i forhold til hinanden i forhold til stenens længdeakse. Dette er nødvendigt på grund af placeringen af noten 7 og fjeren 8.In order to obtain the greatest possible length of the transverse slots 9, these are arranged offset relative to the longitudinal axis of the stone. This is necessary because of the location of the groove 7 and the spring 8.
15 Et isoleringsindlæg 10 er todelt, idet delefugen i form af en trinafsats 11 befinder sig tilnærmelsesvis ved midten af stenen.An insulating insert 10 is bifurcated, the dividing joint in the form of a step ledge 11 being approximately at the center of the stone.
Som det især fremgår af fig. 1 befinder isoleringsindlægget 10 sig på indersiden 12 af ydervæggen 1 og på 20 indersiden af de to endevægge 3 og 4. Samtidig rager isoleringsindlægget i dette afsnit med en udvidelse 13 tilnærmelsesvis halvcirkelformet ind i udsparingen 6 og dækker dennes endekanter 14. På fig. 2 er stenen vist således, at udsparingen 6 danner en åbning i tunnelform. Selvfølgelig er 25 det også muligt med en omvendt oplægning af stenene, dvs. at de to udsparinger altid befinder sig i det øvre område af endevæggene 3 og 4.As can be seen in particular from FIG. 1, the insulating insert 10 is on the inside 12 of the outer wall 1 and 20 on the inside of the two end walls 3 and 4. At the same time, the insulating insert of this section with an extension 13 extends approximately semi-circularly into the recess 6 and covers its end edges 14. In FIG. 2, the stone is shown such that the recess 6 forms an opening in tunnel form. Of course, it is also possible to reverse the stones, ie. that the two recesses are always in the upper region of the end walls 3 and 4.
I de to endevægge 3 og 4 er der på deres fra udsparingen bortvendte over- eller undersider anbragt en paral-30 lelt med endefladerne forløbende isoleringsnot 16, ind i hvilken der ligeledes rager en fra isoleringsindlægget 10 i området fra de to endevægge udgående forlængelse 17.In the two end walls 3 and 4, on their upper or lower sides facing away from the recess, an insulation groove 16 extending parallel to the end faces is provided, in which one also extends from the insulation insert 10 in the region of the two end walls extending.
Til anbringelse af det todelte isoleringsindlæg 10 indskydes dette fra siden af stenen, hvor udsparingerne 35 6 er åbne nedefra eller oppefra, idet forlængelserne i side retningen 13 og 14 sættes eller skubbes henover endekanterne 14 eller ind i isoleringsnoten 16.For placement of the two-piece insulation insert 10, this is inserted from the side of the stone, with the recesses 35 6 open or lower, with the extensions in the side directions 13 and 14 being inserted or pushed over the end edges 14 or into the insulation groove 16.

Som det ses af fig. 1 aftager tykkelsen af isoleringsindlægget i området ved de to endevægge 3 og 4 i retning mod den indvendige væg 2.As seen in FIG. 1, the thickness of the insulating insert in the region of the two end walls 3 and 4 decreases in the direction towards the inner wall 2.
Fig. 4 viser flere oplagte forskallingssten i formind-5 sket målestok.- Herved fremgår også formen af en hjørnesten 18, der har en lukket endevæg, dvs. en endevæg uden udsparing 6, medens indervæggen 2 i det ydre område er forsynet med en udsparing. Yderligere er der på den udefter vendende endeflade anbragt et isoleringsindlæg.FIG. 4 shows several obvious formwork blocks on a reduced scale. This also shows the shape of a cornerstone 18 having a closed end wall, ie. an end wall without recess 6, while the inner wall 2 in the outer region is provided with a recess. Further, an insulating insert is arranged on the outwardly facing end surface.
10 Vil man ikke anvende specielle hjørnesten 18 kan der eventuelt også anvendes en normal forskallingssten som hjørnesten. Hertil er det alene nødvendigt at man afdækker den udefter ragende endeflade med udsparingen 6 på tilsvarende måde med en særskilt isoleringsplade, og enten allerede 15 på fabrikken eller senere på byggepladsen frembringer udsparingen 6 i den indvendige væg 2.If you do not want to use special cornerstones 18, you can also use a normal formwork stone as a cornerstone. For this purpose, it is only necessary to cover the outwardly extending end surface with the recess 6 in a similar manner with a separate insulation plate, and either already 15 at the factory or later at the construction site the recess 6 is produced in the inner wall 2.
Fig. 5 viser fra oven en forskallingssten med afstivningsribber. Som det ses, er der på indersiden af ydervæggen 1 og indervæggen 2 en i vertikal retning gennemgående afstiv-20 ningsribbe 19 i området ved stenens midterplan. Isoleringsindlægget 10, som ligeledes ligger an mod indersiden af ydervæggen 1, er herved udformet således, at det følger formen af afstivningsribben, således at der sikres en ensartet tykkelse af isoleringsindlægget.FIG. 5 shows from above a formwork stone with stiffening ribs. As can be seen, on the inside of the outer wall 1 and the inner wall 2 there is a vertical support rib 19 in the region of the median plane of the stone. The insulating insert 10, which also abuts the inside of the outer wall 1, is hereby designed so that it follows the shape of the stiffening rib so as to ensure a uniform thickness of the insulating insert.
25 Formen af afstivningsribben kan være vilkårlig. IThe shape of the stiffening rib may be arbitrary. IN
almindelighed udformer man afstivningsribben således, at dens forbindelsesvægge i sideretningen forløber skråt i forhold til yder- eller indervæggene.In general, the stiffening rib is designed so that its lateral connecting walls extend obliquely to the outer or inner walls.
