Description

447 142 2 Sagda ytterligare ändamål uppnås med en anordning enligt föreliggande uppfinning, som i huvudsak kännetecknas därav, att den innefattar en gjutform, som är framställd av ett antal trådar eller liknande stänger till nätmönster, och som uppvisar styvhet samt täthet mot omgivande fyllning och uppvisar väsentligen motsvarande form som den eller de plintar, som önskas framställas medelst densamma. Exempelvis kan också an- vändas korrugerad eller på annat sätt förstyvad plåt. Said further object is achieved with a device according to the present invention, which is mainly characterized in that it comprises a mold, which is made of a number of threads or similar rods for net patterns, and which has rigidity and tightness against the surrounding filling and has substantially the same shape as the terminal (s) desired to be made therefrom. For example, corrugated or otherwise stiffened sheet metal can also be used.

Enligt uppfinningen tillgár ett förfarande för framställning av ett antal plintar, som på ritningarna betecknas med siffran 1, och som företrädesvis utgöres av pàlplintar, att a 447 142 man upptager ett lämpligt antal schakt 2 vid ett underlag 3, exempelvis marklagret, till den nivå till vilken man önskar att resp plintar 1 skall sträcka sig. Ett lämpligt antal gjutformar 4, som väsentligen uppvisar motsvarande form som sagda plint 1, placeras på bottnen 2A av sagda schakt 2. Därefter täckes sagda form 4 utmed dess sidor 4A av en fyllning 5, exempelvis makadam, företrädesvis till en nivå 6, vilken en golvplatta 7 eller ett liknande byggnadselement, önskar sträcka sig frán. Lämpligen är plintformen 4 utförd av armeringsnät med tätt sittande stänger 8 eller trådar, så att den erhåller styvhet att motstå trycket från fyllningen 5 samt täthet för att förhindra att fyllning 5 intränger till dess inre. Bottnen 4B och ovandelen 4C av sagda plintform 4 utföres lämpligen öppen.According to the invention, a method for producing a number of terminals, which in the drawings is denoted by the number 1, and which preferably consists of pile terminals, assumes that a suitable number of shafts 2 are occupied at a base 3, for example the ground layer, to the level of which it is desired that the respective terminals 1 should extend. A suitable number of molds 4, which have substantially the same shape as said plinth 1, are placed on the bottom 2A of said shaft 2. Thereafter, said mold 4 is covered along its sides 4A by a filling 5, for example macadam, preferably to a level 6, which a floor plate 7 or a similar building element, wishes to extend away from. Preferably, the terminal form 4 is made of reinforcing mesh with tight-fitting rods 8 or wires, so that it obtains rigidity to withstand the pressure from the filling 5 and tightness to prevent filling 5 from penetrating into its interior. The bottom 4B and the upper part 4C of said terminal form 4 are suitably made open.

En armering 9, som exempelvis består av ett fler- tal armeringselement 10, ll, 12, 13 med öppen eller sluten omkretsform, är anordnad att mottagas i sagda plintform 4 och bilda armering 9 för åtminstone den plint 1, som avses gjutas medelst densamma.A reinforcement 9, which for example consists of a plurality of reinforcing elements 10, 11, 12, 13 with open or closed circumferential shape, is arranged to be received in said terminal form 4 and form reinforcement 9 for at least the terminal 1, which is intended to be cast by means thereof.

Ett antal stödorgan 14, exempelvis av det utföran- det, som visas i fig 14 i form av klykor, kan anbringas i gjut- formens hålformiga inre 4D i syfte att åstadkomma tryck i rikt- ning mot fyllmassan 5, och förhindra att gjutformen 4 tryckes samman på grund av det yttre trycket från fyllmassan 5. Ett handtag 15, som är anbringat vid stödorganet 14, möjliggör upplyftning av detsamma efter ifyllning av gjutmassa 16, före- trädesvis betong, i formen 4. Genom konisk utformning det exempelvis klykformiga stödorganet 14 underlättas fjärmandet av detsamma från formens inre 4D ytterligare.A number of support means 14, for example of the embodiment shown in Fig. 14 in the form of splints, can be arranged in the hollow inner 4D of the mold in order to provide pressure in the direction of the filling mass 5, and to prevent the mold 4 from being pressed. together due to the external pressure from the filling mass 5. A handle 15, which is attached to the support means 14, enables lifting of the same after filling of casting mass 16, preferably concrete, in the mold 4. By conical design the for example clamp-shaped support means 14 is facilitated the removal of the same from the inner 4D of the mold further.

Gjutningen av plint 1 samt en med densamma fast förbunden golvplatta 7 eller ett annat lämpligt byggnadselement sker lämpligen i ett tempo, genom att betong 16 eller annan lämplig gjutmassa 16 tillföres resp form 4 till dess fulla höjd samt till en övre nivå 17, som man önskar att golvplattan 7 skall sträcka sig till. Betongen 16 kommer därvid att mottagas av fyllmassans 5 ovanyta, och lämpliga avgränsningar, exempelvis formväggar, som anslutes till fyllmassan 5 avgränsar det ut- rymme, som avses fyllas med betong 16 och forma sagda golvplatta 7. Härdning av plint 1 och golvplatta 7 sker därefter samtidigt, vilket medför en väsentlig tidsbesparing i jämförelse med tidi- 447 142 4 gare känd teknik.The casting of terminal block 1 and a floor plate 7 or other suitable building element fixedly connected thereto is suitably carried out at a pace, by adding concrete 16 or other suitable casting compound 16 to form 4 to its full height and to an upper level 17, as desired. that the floor plate 7 should extend to. The concrete 16 will then be received by the upper surface of the filling mass 5, and suitable delimitations, for example mold walls, which are connected to the filling mass 5 delimit the space which is intended to be filled with concrete 16 and form said floor plate 7. Curing of terminal block 1 and floor plate 7 takes place thereafter. at the same time, which entails a significant time saving in comparison with previously known technology.

En ytterligare fördel med uppfinningen är, att golvplattan 7 med dess höjdutsträckning kan medräknas i plintens konstruktionshöjd, vilket medför minskat schaktdjup samt mindre betongâtgàng vid gjutningen.A further advantage of the invention is that the floor plate 7 with its height extension can be included in the construction height of the plinth, which results in reduced shaft depth and less concrete access during casting.

Uppfinningen är ej begränsad till de pà ritningen visade och ovan beskrivna utföringsexemplen, utan kan varieras till sina detaljer inom ramen för efterföljande patentkrav.The invention is not limited to the exemplary embodiments shown in the drawing and described above, but can be varied in its details within the scope of the appended claims.
