Abstract

The present invention relates to a method and a device for laying the foundations of a building. The method is characterized in that after the necessary ground work, a box form with removable frame is erected alongside the desired foundation area. The box form consists of two parallel plates (1) of damp-proof material spaced a certain distance apart, the form being open at the top and bottom and subsequently filled with shingle, macadam or similar material (2) and backfill (5) being thereafter placed against the outer side. A mould or support is thus obtained when concreting the foundation element inside, and the walls of the box form are lifted out when the concrete has solidified, thereby providing drainage of the foundations through the remaining shingle/macadam.

Description

503 185 Markarbetena närmast huset kan utföras före gjutning och stomresning. 503 185 The earthworks closest to the house can be carried out before casting and frame erection.

Erforderliga krav pà god dränering uppfyllas automatiskt.Necessary requirements for good drainage are met automatically.

Dessutom krävs inga speciella yrkeskunskaper för utförande av detta sätt.In addition, no special professional skills are required to perform this method.

Kostnaderna för material och arbete kan hållas nere.The costs of materials and labor can be kept down.

Uppfinningen avser även en anordning för utförande av detta sätt, och den kännetecknas av, att såsom form för gjutning av grundelement användes en làdform, bestående av två på visst inbördes avstånd anordnade, parallella väggar av fuktbeständigt material, vilken form år öppen upptill och nedtill, och avsedd att placeras invid den blivande husgrun- den efter erforderliga markarbeten. Förutom ovan anförda fördelar kan nämnas att formen kan återanvändas, och den kan även användas för uthyrning, samt att den lämpar sig för massproduktion.The invention also relates to a device for carrying out this method, and it is characterized in that a box mold, consisting of two mutually spaced, parallel walls of moisture-resistant material, which mold is open at the top and bottom, is used as the mold for casting basic elements. and intended to be placed next to the future house foundation after the required ground work. In addition to the advantages mentioned above, it can be mentioned that the mold can be reused, and it can also be used for rent, and that it is suitable for mass production.

Ritningar: Uppfinningen är exemplifierad i bifogade ritningar, av vilka figur l visar en platta pà mark, figur 2 en detaljbild av plattan och figur 3 plattan uppstålld invid husgrunden. Figur 4 visar en fribärande platta och figur 5 en oisolerad platta samt figur 6 en längdsektion av làdforman.Drawings: The invention is exemplified in the accompanying drawings, of which figure 1 shows a slab on the ground, figure 2 a detailed view of the slab and figure 3 the slab erected next to the house foundation. Figure 4 shows a cantilever plate and figure 5 an uninsulated plate and figure 6 a longitudinal section of the drawer mold.

Utföringsfornerz I figur l visas en av tva parallella plattor (1), exempelvis vàtplyfa, bestående form, uppställd invid den blivande hus- grunden ( betong (3) med omgivande cellplast (4) och puts i '503 185 (ll) efter erforderliga markarbeten.Embodiment Figure 1 shows one of two parallel slabs (1), for example wet plywood, permanent form, erected next to the future house foundation (concrete (3) with surrounding cellular plastic (4) and plaster in '503 185 (ll) after required earthworks .

Sedan denna, upptill och nedtill öppna lagform (lädform l) fyllts med singeﬁ (2) eller makadam sker motfyllning pà utsidan (5), varefter en form för innanförliggande betong- gjutning (3) av grunden erhållits. (4) är cellplastisolering.After this, at the top and bottom open layer form (leather form l) has been filled with singe ﬁ (2) or macadam, backfilling takes place on the outside (5), after which a form for internal concrete casting (3) of the foundation is obtained. (4) is foam insulation.

Singlets styckestorlek är 8-16 mm. Sedan betongen gjutits och stelnat kan formen lyftas upp och bort, se vid lyfthàlet (6) och det övre läget vid (7), se figur 2. I figur 3 visas hur formen förankras vid husgrunden medelst ett plattstäl (10), vilket sedan kan ryckas upp. Man erhåller därvid automatiskt dränering invid husgrunden efter formens bortlyftande.The singlet's piece size is 8-16 mm. After the concrete has been cast and solidified, the mold can be lifted up and away, see at the lifting hole (6) and the upper position at (7), see figure 2. Figure 3 shows how the mold is anchored to the house foundation by means of a flat frame (10), which can then pulled up. Drainage is automatically obtained next to the house foundation after the mold has been lifted off.

I figur 4 visas formen vid en fribärande platta (3) och i figur 5 vid en oisolerad platta (3), d.v.s.cellplastiso- leringen (4) saknas.Figure 4 shows the shape of a cantilevered plate (3) and Figure 5 of an uninsulated plate (3), i.e. the cellular plastic insulation (4) is missing.

I figur 6 visas en längdsektion av formen (l), där de två parallella plattorna hälla sammam pá ett visst avstånd medelst U-formade järn (9) eller liknande. Som nämnts saknar formen bade botten och tak.Som exempel pà dimensioner kan nämnas 2500 mm längd och 196 mm bredd.Figure 6 shows a longitudinal section of the mold (1), where the two parallel plates pour together at a certain distance by means of U-shaped irons (9) or the like. As mentioned, the shape lacks both bottom and roof. Examples of dimensions include 2500 mm length and 196 mm width.

Formen lämpar sig väl för återanvändning, och kan uthyras.The mold is well suited for reuse, and can be rented.

Lyftningen enligt ovan kan ske exempelvis 1-2 dygn efter gjutning. Formen lämpar sig även för massproduktion.The lifting as above can take place, for example, 1-2 days after casting. The mold is also suitable for mass production.

Sättet och anordningen enligt ovan kan varieras på manga- handa vis inom ramen för nedanstående patentkrav.The method and device as above can be varied in many ways within the scope of the following claims.

Claims
