Definitions

  • the present invention relates to a mould for the production of concrete block stones and of the type comprising a support frame for a cellular mould insert, the cells of which are arranged with side walls extending in a direction substantially normal to the plane of the support frame and are, preferably, open at both ends, such that moulding concrete supplied from above to a horizontally disposed mould may intrude downwards into the cells and, after being subjected to vibrations and normally also to a compression in the cells, be expelled from the cells by leaving the cells through the lower ends thereof in response to the entire mould being raised from a support surface, which will thereafter carry the moulded stone members and, optionally, convey them away from the moulding area, if the support surface is laid out as a conveyor.
  • moulds of this type should be constructed in a very robust manner in order to be usable for only a reasonably long period of time.
  • the cell walls should be exchangeably mounted in the support frame, because they are subjected to heavy wear and thus should be renewed from time to time without the entire support frame structure having to be scrapped.
  • the cell wall elements should also be very safely fixable to the support frame in order to resist the strong vibrations to which the frame is subjected, for the required vibration of the moulding material in the cells.
  • Bolts may still be used for fixing the wall elements against the inner sides of the support frame, but now these bolts need not be particularly heavy, as they shall no longer take up the said shear forces, which will be taken up in a broadly distributed manner by the said flanges abutting the lower edge of the support frame.
  • transverse walls or partitions may, generally, project to the joining areas between the wall elements mounted along the opposed inner sides of the support frame, and according to the invention an additional fixation of the transverse wall elements may be obtained by providing these end portion with one or more protrusions engaging into corresponding recesses in the end edges of the wall elements mounted against the inner side of the support frame. Thereby a further anchoring of the transverse cell wall plates will be achieved.
  • the mould shown in Fig. 1 comprises an outer frame portion 2 having sides of heavy plate iron elements provided with bolt holes 4 for bolts 6 for fixing wear resistant, internal lining plates or cell wall elements 8 to the frame 2.
  • the frame 2 is provided with an outer support construction, which, except for an indicated foot flange 10, is not further illustrated.
  • the wear plates 8 are shaped with an outwardly projecting flange 12 which, by the mounting and bolting of the plates, are brought to engage the lower edge of the respective cooperating frame side portions.
  • the frame is provided with a number of transverse partitions 14 made of the same wear resistant material as the plates 8, and these partitions extend all over the width of the frame , i.e. with their opposed ends meeting directly with the frame sides.
  • the plates 8 are adapted such that as shown in more detail in Fig. 2 they will fill out the spaces between the end portions of the partitions 14, whereby these will be firmly held in the length direction of the frame.
  • the transverse wall plates 14 are provided with lower protrusions 16, which project beneath the lower edges of the opposed frame sides, such that these plates will be effectively anchored against being forced upwardly in the mould.
  • recesses 18 are provided, and in level therewith the adjoining end edges of the side plates 8 are provided with protrusions 20 engaging with the recesses 18 so as to further anchor the transverse wall plates, here also against being pushed downwardly from the mould.
  • an inverted anchoring system could be used, whereby the transverse plates 14 could have end protrusions received in recesses in the side plates 8 or in the butt joint areas thereof.
  • both the side plates 12 and the transverse plates 14 will project downwardly below the lower edge of the frame 2. It is desirable that the frame should stand on its support by a relatively thin edge, and because the said holding parts will not have to project all the way to the outer side of the frame they may also contribute by forming a thin support edge, without the thin wear plates being liable to be damaged thereby.
