Definitions

  • the present invention relates to a method pertaining to the casting of prefabricated building units such as walls, building blocks, foundation beams and floor structures, preferably single- course plates to which or in which insulation is fastened or moulded.
  • Patent specification SE 501752 teaches a method of pressing sheets of insulation down into the concrete of the wall plate under vibration. The casting concrete has earlier been poured into the mould.
  • the purpose of the thermal insulation is to thermally insulate the building and to function as a plaster carrier. It has been found that insulation cannot be made too dense from a thermal insulation aspect. It is, after all, the porosity and gas enclosures that provide a thermal insulating effect. A slightly flexible and therewith resilient insulation will yield as it is pressed into the concrete, which must be done whilst exerting heavy pressure against the concrete. The insulation does not have precisel uniform resilient properties and the concrete is not always able to flow out and fill all cavities. This results in walls of uneven thickness. We obtain a smooth surface inside of the building, since the concrete plate is turned inwards, whereas the insulation on the exterior of the building is stepped between the unit parts. These steps may be as much as one centimetre in size. This requires a very thick layer of finishing cement or plaster to be applied in order to obtain a smooth outer surface, therefore greatly adding to costs.
  • This method of producing prefabricated wall elements or units is also encumbered wi l t the drawback of requiring the application of very heavy forces in pressing down the wall insulation, which has a very wide surface area.
  • the method according to our invention enables units of optional lengths and having a width of 2.4 m to be fabricated with no difficulty. It is also conventionally possible to cast a concrete plate on top of the thermal insulation, although this requires a piece of solid workmanship in treating the surface of the concrete plate so that it becomes straight, smooth and free from pores.
  • Upstanding forms are also used for wall fabrication, sometimes in mutually adjacent relationship, so-called battery forms.
  • the height of the wall units must correspond to the height of a storey plus the height of a floor structure. During casting, this height produces a vibrating concrete column (cf. liquid column) that has an enormous explosive effect and generates horizontal forces that greatly exceed a purely stationary "concrete liquid".
  • the insulation is subjected to still greater compression than when the insulation is pressed into a horizontal concrete mass, and still greater variations in thickness occur.
  • the present invention also provides a solution to the aforesaid problem.
  • the object of the present invention is to improve the tolerances on primarily the thickness of a prefabricated wall unit with moulded-in insulation.
  • Face cutting processes waste material and generate a noisy and dusty environment.
  • the insulation is provided with grooves that are filled with concrete as the units or elements are cast. These grooves can be given the form of vertical, horizontal or inclined channels as seen in relation to an upstanding, mounted wall unit.
  • the channel bottoms are made 1 arger inwardly of the insulation as seen from the surface, e.g. have a dovetail shaped cross-section.
  • a suitable tool is a conical cutter with the base at its end.
  • the channels, or grooves may have a depth of from 1 to 2 cm, for instance. These channels will not weaken the sheet of insulation to any appreciable extent, considering that these sheets will normally have a thickness of at least 200 mm.
  • This casting method is intended for use in constructions described in the original application, with toothed or finger-like attachment between floor structure and wall plates. This supporting method results in purely centrally vertical loading in the wall plates and eliminates the need of reinforced T-beam webs.
  • the casting concrete need not rise to a particularly high level when the concrete plate lies undermost, e.g. against a steel mould, as compared to the height it is required to rise in the case of reinforced T-beam webs, which are normally a decimetre in height.
  • casting is carried out in accordance with the following method. Any forms required for window cavities and other cavities in the wall concrete plate are applied conventionally. Wall reinforcement is placed in the mould.
  • the prepared insulation sheets Prior to casting, the prepared insulation sheets are fixed at the correct unit thickness with spacing blocks against the mould for the concrete. Or are lifted from the mould and held in place with the aid of suction cups through the medium of a vacuum, without requiring the use of blocks. There is always a risk of blocks being torn away by the heavy concrete mass; see below. Suitable stop means prevent the insulation sheets moving from the mould as the concrete is poured thereinto. SOLUTION
  • the fastener channels in the insulation to be filled with concrete are suitably orientated in the longitudinal direction of the slope so that no unnecessary air pockets will form.
  • the concrete is poured in from the upper edge of the slope, optionally while vibrating.
  • the upper edge can be formed by any side of the unit whatsoever.
  • the concrete is poured from the long side of the unit.
  • w ioh provides stability and straightness in a conventional manner.
  • concrete may also be injected centrally through such holes or openings provided in the insulation.
  • the mould may very well lie horizontally in this case.
  • Plate reinforcement is spaced from the insulation sheet and holds the sheet m placo, so that the sheet will not float up.
  • This casting method enables the insulation sheets to be made in large units, and also enables holding means to be provided against the overlying mould, to avoid the insulation floating up.
  • the concrete/casting compound poured in the upper edge of the gap in accordance with the aforegoing runs readily down into fastener channels and pockets for windows, etc., wherewith the air is pressed up towards the overlying planar mould and has a much broader way out, which facilitates filling-out the mould with casting compound.
  • Vibrators placed along the sloping mould can be switched on and off respectively as the gap is filled. This will depend on whether or not vibration is required; see below.

Abstract

La présente invention concerne un procédé de fabrication de murs préfabriqués ou de structures de plancher. On coule, de préférence, les murs et les structures de plancher à plaque mince en une seule fois, l'isolation étant solidaire du plancher. Pour éviter une compression inégale de l'isolation, le béton est versé dans une forme inclinée ou verticale qui est amenée dans une position horizontale après avoir été remplie de béton. Les murs peuvent être fabriqués sans ponts thermiques provoqués par la pression du béton sur l'isolation.
