Definitions

  • the present invention concerns a method for making walls of a prefab building.
  • the invention concerns a method for making walls of a prefab building which consists of prefabricating wall parts that fit into each other by joining stones according to a certain bond pattern, whereby certain stones that are not adjacent protrude on the side edges so as to form teeth which can mesh with a slight play between two protruding teeth of an adjacent wall part to be built on, on the one hand, and by assembling these wall parts on the building site by pushing them into each other with their teeth and by joining them on the other hand.
  • the wall parts are hereby obtained by gluing bricks directly onto each other.
  • This method is very suitable for making inner walls, as the aspect of these walls hardly matters, as they are usually plastered afterwards.
  • the glue should preferably be able to overcome the tensile force of the wall's weight so as to prevent the wall parts from falling apart or at least avoid a weakening of the wall parts.
  • the present invention aims to remedy one or several of the above-mentioned and other disadvantages.
  • the present invention hereby concerns a method for making walls of a prefab building which consists in prefabricating wall parts that fit into each other by joining stones according to a specific bond pattern, whereby certain stones that are not adjacent protrude on the side edges so as to form teeth which can mesh with a slight play between two protruding teeth of an adjacent wall part to be built on, on the one hand, and by assembling these wall parts on the building site by pushing them into each other with their teeth and by joining them on the other hand, whereby, during the production of the wall parts, use is made of a mould which is provided with a base plate onto which has been provided an embossed grid with a rectangular grid pattern, whereby every grid rectangle corresponds to a lateral face of a stone and the grid lines have a certain width so as to form a joint between the stones, and whereby the method consists among others in placing the stones with their lateral faces on the base plate between the grid lines, in providing mortar between the stones after the stones have been put in the mould, and in taking the wall part out of
  • An advantage of this method according to the invention is that wall parts are obtained in a simple manner which are provided with a joint, such that the method can also be easily applied to make outer walls of a prefab building.
  • Another advantage of such a method according to the invention is that the stones can be arranged very quickly in the mould, as the stones are automatically kept in place thanks to the relief of the grid.
  • the method can also be easily automated, making it possible to save on labour and as a consequence possibly also on wages.
  • the walls of a prefab building made of stone wall parts are more solid than those of the known conventional prefab buildings.
  • Another advantage of the method is that it takes far less time to erect a stone building on the building site itself than in the case where the walls have to be entirely built on the spot.
  • Another advantage of this method according to the invention is that the wall parts can be easily stacked and joined so as to form a wall by means of a hoist in the shape of a crane or the like, such that no scaffolds need to be erected during the construction of the building.
  • reinforcement bars are provided between the stones, whereby according to an even more preferred method, reinforcement bars are provided between the stones in the longitudinal direction of the stones as well as in the height.
  • This method according to the invention is advantageous in that, after the mortar has set, the wall parts are particularly robust and can withstand a tensile strain as such, such as for example during the transport of the wall parts.
  • a number of reinforcement bars in the height are additionally provided with a ring at one far end, whereby said reinforcement bar is placed such between the stones in the wall that the ring protrudes from the mould or the wall part.
  • the invention also concerns a building stone which can be used with a method according to the invention as explained above, whereby this building stone is specially designed to serve as the tooth of a wall part to be formed, and whereby this building stone has been excavated over a certain thickness of a part of its upper side and/or lower side, such that the stone has a smaller height over this part than on certain side edges.
  • the building stone is preferably provided with a rectangular side face and a rectangular crosscut face which corresponds in size to the lateral face and crosscut face of an ordinary stone as is used in the above-described method.
  • Such a building stone can be easily used in the above-mentioned method as it can be provided with its rectangular lateral face on the side edges of the mould between the grid lines with the rectangular crosscut face directed outwards, such that the singular, excavated shape of the stones forming the teeth does not cause any problems when filling the mould, and the protruding teeth, after the wall parts have been assembled, still look like normal stones.
  • the building stone prefferably be provided with a passage in the height, and the building stone is preferably symmetrical in relation to a plane cutting the stone along its height.
  • the above-mentioned passage in the building stone is preferably provided such that, when a wall part is provided with teeth formed of such building stones, the different passages will be aligned in relation to each other, such that when assembling two wall parts by making the teeth mesh, a columnar passage is obtained in which a reinforcement bar can preferably be provided, after which both wall parts can be coupled together by filling the columnar passage with a mortar.
  • part of the mortar when filling the columnar passage, part of the mortar can also be provided in the part of the building stones which has been excavated, such that a connection can be obtained in the above-mentioned column with reinforcement bars provided in the longitudinal direction between the stones and which are bent in the excavations.
  • the invention also concerns a mould to be used with a method as explained above, whereby this mould is provided with a base plate on which has been embossed a grid having a rectangular grid pattern with a cross pattern which corresponds to the pattern that is typically formed by the joints of a brick wall, whereby the grid lines have a width which corresponds to a typical joint width.
  • the mould is preferably provided with standing walls on the outside having a height which is about the same as that of a typical stone width or somewhat larger than said stone width, and the grid lines are formed of laths provided with a sealing on their side edges.
  • An advantage of such a mould is that it can be easily filled with stones, whereby the sealing at the grid laths makes sure that, after the mould has been filled with mortar, there will be no leaks and, as a consequence, the joint to be formed remains open.
  • this adjusted height of the mould makes it possible to provide mortar between the joints by daubing it for example with a smoothing trowel or the like over the face of the stones provided in the mould, such that a wall part can be obtained having the thickness of the width of a stone.
  • the mould 1 according to the invention represented in figures 1 and 2 is formed of a base plate 2 provided with standing walls 4 on the outer edges 3.
  • Such a mould 1 can be used to make the walls of a prefab building, in particular wall parts 5 of such walls, as represented in figures 6 and 7 , according to a method of the present invention.
  • the height A of the standing walls 4 is preferably about as large or somewhat larger than a typical stone width A' of a stone 6 with which the wall parts are made.
  • Every grid rectangle 8 of the grid 7 corresponds to a lateral face 9 of a stone 6.
  • the grid lines 10 of this grid 7 have a width B which corresponds to a typical joint width B'.
  • the grid lines 10 are formed of laths 11 provided with a sealing 13 on their side edges 12.
  • the sealing 13 may for example be formed of a rubber strip glued on the side edges 12 of the grid laths 11.
  • a first step of the method according to the invention consists in placing the stones 6 with their lateral faces 9 on the base plate 2 between the grid lines 10.
  • the building stones 16 forming the teeth 14 are made with a rectangular lateral face 20 and a rectangular crosscut face 21 which have the size of the lateral faces 9 and the crosscut faces 22 of the ordinary stones 6.
  • the lateral face 20 is placed on the base plate 2 of the mould 1 and the crosscut face 21 is directed towards the side edge 15 of the mould 1.
  • the building stones 16 are preferably symmetrical in relation to a plane cutting the stone 16 over its height C.
  • the stones 16 can be easily used on both side edges 15 of the mould 1, which would not be obvious, for example, if they were not symmetrical to the above-mentioned plane.
  • a filling element the size of a part of a stone 6 is provided on the side edges 15 of the mould 1, every other row between the stones 16 forming the teeth 14, which filling element links up closely with the stones 16 of the adjacent rows forming the teeth 14, with the last stone 6 of the row in which the filling element 23 is situated and with a standing wall 4 of the mould 1.
  • Said filling element 23 can for example be made of a polymer foam or any other durable material whatsoever, such that it can be re-used.
  • reinforcement bars are preferably provided between the stones 6 and 16 according to the invention, as is illustrated in figures 4 and 5 .
  • reinforcement bars 24 are provided between the stones 6 and 16 in the longitudinal direction DD' of the stones 6 and 16, as well as reinforcement bars 25 in the height EE' of the stones 6 and 16.
  • the reinforcement bars 24 for the longitudinal direction DD' are provided with a buckle 27 at both far ends which is such that, as is represented in detail in figure 5 , the buckled far end 26 fits in the cavity 19 of the stones 16 forming the teeth 14.
  • the reinforcement bars 25 for the height EE' are preferably bent in a shape which corresponds to the pattern formed of the grid lines 10 on the base plate 2.
  • the sealings 13 hereby prevent the mortar from seeping through to the base plate 2, as a result of which the face of the wall part 5 resting on the base plate 2 would be soiled.
  • the filling elements 23 prevent the part between the building stones 16 forming the teeth 14 from being filled with mortar.
  • the wall part 5 is taken from the mould 1, leading for example to a result as is represented in figures 6 and 7 .
  • a wall part 5 is hereby obtained having a thickness which is equal to the width of a stone, and the stones 6 of the wall part 5 are coupled by the mortar as well as by the reinforcement bars 24 and 25 in the joints 34 between the stones 6.
  • An advantage of such a wall part 5 is that its aspect and weight hardly differ from those of the walls that are built in a conventional manner.
  • the mortar may hereby be a conventional mortar which is applied in an amount that can be compared to the amount used in the conventional building methods.
  • the above-mentioned rings 30 protruding from the wall part 5 can be easily used to transport the wall part 5 to the building site and during the installation of the wall part 5 on the building site, after which the rings 30 can be removed for example with tongs or a grinding disc or the like.
  • the stones 16 forming the teeth 14 are preferably provided with a passage 31 in the height EE'.
  • part of the mortar 33 is provided in the excavated part 19 of the stones 16 forming the teeth 14, such that a connection with reinforcement bars 24 can be obtained in the above-mentioned column provided in the longitudinal direction EE' between the stones 6 and 16.
  • fastening means 36 which protrude from the face of the wall part 5.
  • Such fastening means 36 may for example have a shape as is represented in figures 10 and 11 .
  • fastening means 36 can be used to mount a wall part 5 of an outer wall 35 made according to this alternative method at a certain distance from an inner wall 37 so as to form a cavity wall.
  • Hook-shaped fastening means 38 are hereby provided in the outer wall 35 according to figure 11 on the one hand, and fastening means 39 are provided in the inner wall 37 according to figure 10 on the other hand, on which struts 40 can be fixed, for example by screwing them in the fastening means 39 or the like.
  • the latter struts 40 are provided with openings 41 in which the hook-shaped fastening means 38 of the outer wall 35 can be hooked.
  • the fastening means may be provided with means which make it possible to adjust the thickness of the cavity wall.
  • the fastening means 39 can be provided with fixing holes 42 which are provided for example every cm at different distances from the inner wall 37, and which can be used for fixing the above-mentioned struts 40 at different distances from the inner wall 37.
  • the invention is by no means restricted to the method described as an example, nor to the building stones and mould applied thereby; on the contrary, such a method, building stones and mould can be made according to different variants while still remaining within the scope of the invention.
