Definitions

  • the invention relates to a mold for the simultaneous production of a plurality of hollow concrete blocks, specifically those hollow blocks which each have at least two centering projections on their top and bottom and a correspondingly large number of centering recesses on the opposite surface for engagement with the centering projections of the adjacent hollow block.
  • Such specially designed hollow concrete blocks have the advantage over the usual smooth and grouted with each other stones that they can be installed without leveling mortar, because their outer dimensions are extremely precise, d. H. are manufactured with correspondingly narrow tolerances. It is therefore only necessary to use a suitable adhesive, for example an epoxy adhesive, to connect the stones, which connects the adjacent stones in their horizontal and vertical joints.
  • a suitable adhesive for example an epoxy adhesive
  • the centering projections or recesses provided in each case are arranged so that the stones in the longitudinal and transverse association ge can be set.
  • the stones therefore have depending on the size - depending on whether there is a quarter stone, a half stone or a full stone - on the top at least two - or four, six, eight or more - centering projections and on the underside an equal number of correspondingly shaped centering recesses.
  • these centering projections engage in the centering recesses provided on the underside of the adjacent upper counterstone and in this way bring about the dimensional stability of the wall in the longitudinal and vertical directions.
  • the invention is therefore based on the object to design the form for eliminating the disadvantages such that it can be changed quickly and easily for the production of stones of various dimensions and also has a sufficiently large stability to the stones for subsequent treatment steps or the like being able to remain on certain parts of the mold without having to move the stones separately.
  • the mold according to the invention consists of at least three parts - a lower rigid base plate, a molding box and an upper die - the formation of these three essential molded parts can be carried out in such a way that the overall shape can be changed quickly and easily to produce stones of versatile dimensions can.
  • Such a redesign of the shape is particularly simple because the corresponding individual parts of the molding box and / or the die are screwed together, so that the individual parts can be replaced without great effort depending on the stone models to be molded. Parts of the mold that are subject to particularly high wear can be replaced very quickly. It also makes it possible to change the number of full, half and quarter stones to be produced in one mold at short notice by changing the individual parts.
  • the screwed design of the mold therefore enables the quick replacement of individual wear parts and the quick changeover to other stone models while continuing to use permanent standard parts.
  • the lower base plate used in the mold is designed as a rigid production range, there is not only sufficient strength and rigidity of this lower base plate, but there is also the possibility of handling a large number of the shaped hollow concrete blocks after casting and curing as desired to be able to without the stones of the un need to remove the other base plate. It is therefore possible, for example, for the stones to be fed to a drying station after the actual shaping, without having to remove them from the production range, which makes the entire production process considerably easier and also accelerates this process as a whole.
  • the lower rigid base plate designed as a production pallet can be used on both sides, ie. H. has depressions of different patterns both on their top and on their underside, so that the top or bottom of the production range can be used in conjunction with the other parts of the mold for producing the desired stones, as required.
  • the concrete hollow block 1 shown in FIGS. 1-3 which, in contrast to the embodiments according to FIGS. 4 and 5, is designed as a so-called solid block, has an elongated cuboid shape with, for example, the dimensions in width 20 cm, length 40 cm, height 15 cm and has in its interior two continuous recesses 2 arranged one behind the other in the longitudinal direction of the stone 1, the cross-section of which has the shape shown in particular in FIG. 2.
  • the stone 1 is provided with eight recesses 3 on its upper side and with a correspondingly large number, ie also with eight projections 4, on its underside.
  • the projections 4 point upwards, while during the manufacture of the stones 1 the projections 4 point downwards, as will be explained below.
  • the depressions 3 and projections 4 used for centering are of a complementary shape and conical in the manner shown in FIGS. 1 and 3, the arrangement being such that two of the depressions 3 or projections 4 are located on either side of the longitudinal median plane of the stone 1 lie opposite and two pairs of such depressions 3 or projections 4 lie in the corners of an imaginary square, as can be seen particularly clearly from FIG. 2.
  • the hollow concrete block block 11 shown is designed as a half block 11, the dimensions of which practically represent the halved hollow block block 1 according to FIGS. 1-3.
  • the half-stone 11 accordingly has four conical centering recesses 3 on its one surface, which are grouped at regular intervals around the single recess 2 of the half-stone 11 and are aligned with four centering projections 4 provided on the opposite surface of the half-stone 11.
  • FIG. 5 corresponds to the half stone 11 according to FIG. 4 and accordingly has only two centering recesses 3 or centering projections 4, which are arranged on both sides of the half recess 22 of the quarter stone 21.
  • FIGS. 6 and 7 serves for the simultaneous production of several of the hollow concrete blocks 1 and 11 and 21, respectively. This is made up of three parts and consists of a lower rigid base plate 5, a molding box 6 and a molding die 7.
  • the lower base plate 5 is so rigid that it serves as a manufacturing pallet, i.e. it not only carries the hollow concrete blocks 1 or 11 or 21 on their respective upper sides during their forming, but also during further steps subsequent to the forming, such as drying, moving to the storage place, etc.
  • this manufacturing range 5 is made of solid material and consists of sheet steel, cast iron, plastic, aluminum or other suitable rigid materials.
  • the manufacturing pallet 5 Since, as already explained, the centering projections 4 of the stones 1 or 11 or 21 point downwards during their manufacture, the manufacturing pallet 5 has on its upper side appropriately designed conical depressions 41 which are in a pattern of the centering projections to be provided for the stones 4 corresponding patterns are arranged.
  • the molded box 6 to be placed centered on the production pallet is formed as a screw construction from two longitudinal walls 8 and two transverse walls 9, which are fixed to one another by screw connections 10.
  • Transverse molding box brackets 12 are welded to the longitudinal walls 8 of the molding box 6 and centering pieces 13 are also screwed on the underside in order to center these two molded parts against one another when the molding box 6 is placed on the production pallet 5.
  • the inner sides of the longitudinal walls 8 and the transverse walls 9 bear wear plates 14, which are also fixed there by easily detachable screw connections 10.
  • the molding box 6 is divided by dividing walls 15 running parallel to the longitudinal walls 8 into a corresponding number of molding compartments, the dimensions of which are those of the stones 1, 11, 21 to be molded correspond.
  • cores 16 are inserted into these mold compartments in the manner shown in FIGS. 6 and 7, each of which is connected to one another by a web 17 running parallel to the longitudinal wall 8 of the molding box and has dimensions which correspond to those of the stones 1 and 11 and 21 respectively provided recesses 2 and 22 correspond.
  • the shape shown is used to simultaneously form three of the hollow blocks 1 according to FIGS. 1-3 as well as a half stone 11 according to FIG. 4 and a quarter stone 21 according to FIG. 5.
  • the half-stone 11 and the quarter stone 21 are formed in a single mold compartment - the rightmost mold compartment according to FIG. 6 - so that for this reason the cores 16 which effect the formation of the corresponding recesses 2 and 22 also have a corresponding design and include an intermediate core 16 'which is connected to the webs 17 of the two cores 16.
  • the number of solid bricks 1 and / or half bricks 11 and / or quarter bricks 21 which can be produced simultaneously in a single mold can be changed at short notice by exchanging the corresponding molded individual parts which are only connected to one another by screwing.
  • FIG. 7 With regard to the design of the die 7, reference is expressly made to FIG. 7, from which it can also be seen in particular that the die 7 for each of the four mold compartments provided in the mold according to FIG. 6 has two on the underside on a common one Plate 18 has fixed bracket 19, on the underside of which an end plate 20 is welded. Each of these end plates 20 carries on the underside a form plate 23 fastened to it by means of screwing 10, which forms the smooth upper side of the stone or stones located in the relevant form compartment. On this form plate 23, on the underside - likewise by means of screw 10 - conical protrusions 31 are fastened, which are used to form the centering recesses 3 on the top of the respective stones 1, 11 and 21 in the form.
  • the molding die 7 has been lowered onto the top of the concrete located in the molding box 6 and has compressed this concrete to the desired stone height by pressure and / or vibration. Since the concrete fills the conical recesses 41 of the production pallet 5, the centering projections 4 of the stones 1, 11, 21 formed in each case are also formed. At the same time, the conical centering recesses 3 are also pressed into the opposite surface of the stones by the projections 31 provided on the underside of the die 7.
  • the die 7 and the molding box 6 are moved upwards in the order mentioned.
  • the finished stones 1, 11, 21, on the other hand remain on the production pallet 5 and are brought together with the production pallet 5, for example, into a drying station, whereupon only the finished stones 1, 11, 21 can be removed from the production range 5. This saves one operation in each case, since the stones no longer have to be removed separately from the lower mold part.
  • the manufacturing pallet 24 shown can be used on both sides and, for this purpose, not only has the depressions 41 used to form the stone projections 4 on its upper side in the manner already described, but also has on its underside corresponding depressions, the depressions provided on the underside of the production pallet 24, however, being provided in a different number and in a different pattern, as can be seen in particular from FIG. 9.
  • This makes it possible to use one and the same production range - by using the top side - for example simultaneously to produce four hollow blocks 1 with the described shape on the one hand and - by turning the underside of the production range 24 upwards - on the other hand to simultaneously produce three hollow blocks 1 ', but these of larger dimensions.
  • the dimensions of the hollow blocks 1 or 1 'to be formed with the top or bottom of the production pallet 24 are indicated by the solid or dashed lines in FIG. 9.
  • the production pallet 25 shown can also be used on both sides and therefore has the recesses 41 used to form the stone projections 4 on both the top and the bottom.
  • the production pallet 25 is double-shell, for example made of sheet steel, and has therefore two sheet metal shells 26, 27 which are weldable and cold-formable. Accordingly, the conical recesses 41 are pressed into the sheet metal shells 26, 27. As can be seen from Fig.
  • the two sheet metal shells 26, 27 are after joining together at their circumferential outer edge with a weld seam 28 and at the points of contact of their conical recesses 41 with the corresponding surface of the respective other sheet metal shell 26 and 27 by spot welding by means of one each Welding point 29 connected.
  • a rigid structure is also formed, which in the form described in connection with FIGS. 6 and 7 serves as a lower base plate and at the same time as a production pallet.
