Definitions

  • the invention relates to a casting mould system according to the preamble of the appended independent claim.
  • the invention also relates to a casting mould for manufacturing an element, which has been manufactured using a casting mould system according to the invention as well as a method for manufacturing an element using the casting mould system and a wall element.
  • the document GB2355024 discloses a method for producing building panel, which comprises an insulating layer and a layer of concrete.
  • the insulating layer comprises a series of peaks and troughs providing a mould into which a concrete is cast.
  • the edge of the panel can be constructed by cutting the peak located at the edge of the insulating layer in a half so that one half of the peak remains integral with the foam layer and the second half is turned upside down and placed over the first half.
  • An object of the present invention is to provide a casting mould system that enables an easy, fast and flexible realisation of a casting mould, whereby the elements can for example be cast at the construction site.
  • the casting mould system, and the method for manufacturing an element according to the invention are primarily characterised in what is presented in the characterising parts of the appended independent claims.
  • a typical wall element comprises a cast layer and a heat insulating layer in connection with it, which element is manufactured as casting on flat according to a method that uses a casting mould system according to the invention.
  • the casting mould system enables the manufacturing of the elements in such a manner that the heat insulating layer functioning as the bottom-plate of the casting mould is made part of the cast element.
  • the casting mould system according to the invention enables the easy and fast manufacturing of a casting mould required for casting elements comprising a cast layer and a heat insulating layer in connection with it, as a result of plates and side mould pieces compatible with each other, since the side mould pieces of the casting mould systems can be fixed to the grooves of the plates forming the bottom of the casting mould, without a separate fixing.
  • the casting mould system according to the invention also enables easy modifiability of the casting moulds, since the plates of the casting mould system comprise typically grooves on the whole area of the plate and since the casting mould can be rapidly assembles from pieces that are compatible with each other.
  • the casting mould system comprises a plate or plates that form the bottom (bottom plate) of the casting mould, and side mould pieces that are arranged into the grooves on the surface of the bottom plate, forming the vertical walls of the casting mould.
  • the side mould pieces are typically essentially perpendicular to the bottom plate of the casting mould.
  • the side mould pieces are arranged tightly one against the other, whereby uniform casting mould walls can be formed.
  • the side mould pieces do not need to be separate fixed to the bottom plate, but they can be attached to the grooves in a sufficiently strong manner and thereby they are also easily detachable after the casting step.
  • the plate/plates forming the bottom plate of the casting mould according to the invention also form, at the same time, the heat insulating layer of the finished element, which layer is in connection with the cast layer.
  • the plate or plates of the casting mould system can be manufactured from any heat insulating material suitable for the use, which material's heat conductivity (lambda 10-value) is less than 0.1 W/(m K)
  • the side mould pieces of the casting mould system can be manufactured in any suitable material for this use.
  • the plate/plates and side mould pieces of the casting mould system have been manufactured of cellular plastic such as extruded polystyrene (XPS), expanded polystyrene (EPS) or polyurethane (PIR/PUR).
  • XPS extruded polystyrene
  • EPS expanded polystyrene
  • PUR polyurethane
  • the plate/plates and the side mould pieces are manufactured from a same material.
  • the plate or plates and the side mould pieces are manufactured from extruded polystyrene.
  • the plates manufactured from a heat insulating material used in the casting mould system can also be coated, whereby the core layer of the plate is made from any of the afor
  • the thickness of the plates used in a casting mould system according to the invention is typically 50-600 mm, more typically 80-500 mm and most typically 100-400 mm.
  • the casting mould system according to the invention does not place any limitations as to the shape or size of the plates used.
  • the plates of the casting mould system usually have a rectangular shape, which comprises a first planar surface and a second planar surface, and a first and second parallel long side edge and parallel first and second short side edges, which are perpendicular to the long side edges, delimiting the surfaces.
  • the length of the long side edge of the wall plate is typically 600 to 6000 mm, more typically 1200 to 4000 mm, even more typically 1200 to 3000 mm.
  • the length of the short side edge of the wall plate is typically 300 to 1500 mm, more typically 500 to 1300 mm, even more typically 600 to 1200 mm.
  • the long side edges of the plate define the longitudinal direction of the plate and the short side edges of the plate define the lateral direction of the plate.
  • At least one of the planar surfaces of the plate comprises grooves in at least the longitudinal and/or lateral direction of the plate, on the area of the whole planar surface of the plate.
  • several grooves are on both the lateral and the longitudinal direction on the area of the whole planar surface of the plate.
  • the distance between the grooves may vary, typically the distance between the grooves is about 80-150 mm, most typically about 100 mm.
  • the distance between the grooves may also be different in the lateral direction and the longitudinal direction of the plate.
  • the width of the grooves may vary, depending on the thickness of the side mould pieces used, typically the width of the grooves is about 20-50 mm.
  • the width of the grooves arranged on the surface of the plate is about 25 mm.
  • the depth of the grooves may also vary, typically the depth is about 10-25 mm, which enables the arranging into place of the side mould pieces.
  • At least one edge of the side mould pieces that are part of the system is formed such that the side mould pieces are tightly arrangeable into the grooves of the plates.
  • the grooves on the plates of the casting mould system according to the invention enable the easy modifiability of the casting mould. For example, if the distance between the grooves is 100 mm (measured from the middle to the middle), the width of the groove is 25 mm and the thickness of the side mould pieces is 50 mm, then the side mould pieces may be arranged on the bottom plate at a minimum of 25 mm spacing, at any position on the plate.
  • the grooves on the surface of the bottom plate both in the lateral and the longitudinal direction enable the positioning of the side mould pieces vertical against each other.
  • the grooving of the plates enables for example in a casting mould for a wall element the free positioning of openings for windows and doors and thereby different elements can be easily manufactured by the casting mould system.
  • the side mould pieces belonging to the casting mould system are typically manufactured in such a manner that one larger plate comprises several side mould pieces.
  • the side mould pieces are readily formed on an entire plate in such a manner that they can be detached from each other by bending.
  • the side mould pieces are easy to manufacture and to transport as one larger plate.
  • the length of the side mould pieces is typically 600 to 6000 mm, more typically 1200 to 4000 mm, even more typically 1200 to 3000 mm.
  • the height of the side mould pieces can vary, typically 50-200 mm and most typically 100-150 mm.
  • the thickness of the side mould pieces is typically 40-100 mm, most typically 50 mm.
  • the cross-section of the side mould pieces may vary and can be freely chosen depending on the requirements set by the element to be manufactured.
  • the cross-section of the side mould piece is a rectangle, of which one side edge a tongue (male tongue and groove) has been formed, which tongue is arrangeable into the groove on the plate.
  • the width of this tongue is compatible in size with the grooves arranged on the plates.
  • the other edge of the side mould pieces which does not comprise a tongue, i.e. a tongue and groove, enabling the fixing to a plate, can be freely formed depending on the application.
  • a casting mould system according to the invention may comprise several different and differently shape side mould pieces, which are at one of their edges arrangeable into the grooves in the plate.
  • the casting mould system comprises two or more plates, which edges of the plates to be arranged one against the other are formed compatible with each other.
  • the plates are arranged tightly one against the other, forming a uniform bottom plate of the casting mould.
  • tongues and grooves are formed on the edges of the plates, enabling tight fixing of the plates to each other via the tongue and groove joint.
  • the side edges of the plates that are arrangeable one against the other are half-grooved, that is, the side edge of the wall plate comprises a step-wise form, in which a tongue (male tongue) is formed on one side of the side edge and a groove (female groove) is formed on the other side of the edge, into which groove the tongue (male tongue) of the plate next to it is positioned, to form a tight joint.
  • a tongue male tongue
  • a groove female groove
  • other types of tongue and groove joints can be used to fix the plates to each other.
  • a casting mould system according to the invention is thus adapted for manufacturing any size of casting mould by using standard sized plates.
  • the plate or plates forming the bottom plate is/are positioned on an even support. If several plates are needed to form a bottom plate of required size, they are arranged tightly one against the other via for example a tongue and groove joint or via another similar form. Alternatively, the plates can be fixed to each other by gluing. Thereafter the side mould pieces are arranged to the grooves of the bottom plate to desired locations, depending on the element to be cast. The side mould pieces are shortened or extended by gluing according to the need, so that uniform casting mould walls can be formed. At the corners of the walls, the side mould pieces are positioned tightly against one another at right angles.
  • the required openings for windows and doors are formed into the casting mould by the side mould pieces.
  • the side mould pieces do not need to be fixed to the bottom plate but instead they are attached in place in a sufficiently tight manner with the grooves in the plates, which grooves are compatible with the side mould pieces. If necessary, the side mould pieces can be fixed to the bottom plates by gluing or mechanically.
  • the casting mould is finished with the bottom plate and the side mould pieces, the casting mould is ready for iron reinforcement.
  • the iron reinforcement may be done using regular products used in iron reinforcement.
  • the mould can be filled with casting compound.
  • the side mould pieces of the casting mould are usually dismounted, when the casting compound has reached a sufficient strength. In some cases, the side mould pieces can however be left in place as part of the cast element.
  • the bottom plate of the casting mould remains a part of the cast element.
  • a casting mould system according to the invention is suitable for use in the manufacturing of all types of elements, which elements comprise a heat insulating layer and a cast layer in connection with it.
  • the casting mould system according to the invention is especially used for manufacturing wall elements.
  • the casting mould system according to the invention enables an easy manufacturing of casting mould and thus the elements can be for example cast only at the construction site, whereby the elements do not need to be separately transported to the construction site.
  • Figure 1 illustrates a plate 1 according to a casting mould system according to the invention, which plate comprises a first planar surface 4 and a second planar surface 5, of which planar surfaces at least one comprises grooves (6, 6') arranged on the surface of the plate in the longitudinal and lateral direction of the plate.
  • Figure 2 shows the cross-section of the plate 1.
