Definitions

  • the present invention relates to a brick with insulating material body and a method for producing such a brick.
  • pourable materials can be poured into the cavities and then harden depending on the type of material.
  • mineral foams offer good insulation values and such materials are, for example, in EP 0 146 529 A2 , DE 20 2011 107 411 U1 , EP 3 156 383 B1 and DE 10 2015 013 396 A1 shown.
  • other properties of the brick are also decisive in order to be used as a building material, such as sound insulation as well as stability and load-bearing strength.
  • the manufacturing effort plays a decisive role.
  • the object of the present invention is therefore to provide a brick which is easy to manufacture and has improved sound and heat insulating properties.
  • a brick according to the invention comprises a brick interior enclosed by brick outer walls, at least one of the brick outer walls being designed as a joining surface for the lateral connection to further bricks.
  • the brick further comprises at least one insulating material body arranged vertically in the brick interior, the insulating material body having a polygonal cross section, in particular with three, five or more cross-sectional corners.
  • the polygonal structure of the insulating material body improves the acoustical properties of the brick and thus the wall that is built from these bricks, since the longitudinal sound conduction is reduced.
  • the side lengths differ of the cross-section by a factor of approximately 0.5 to 1.
  • honeycomb shape that is to say an octagonal cross-section
  • the lateral connection of two bricks can be done by simply lining them up or additionally using mortar or other materials that promote adhesion.
  • the connection can be detachable.
  • the insulating material body preferably comprises a foam-like insulating material.
  • a foam-like insulating material for example, mineral foams, as shown in the prior art cited above, can be used.
  • Foam-like insulating material is light and has particularly good heat and sound insulating properties.
  • the brick comprises one or more vertically arranged cavities, which each have a polygonal cross section, in particular with three, five or more cross-sectional corners, and are each filled with a correspondingly shaped insulating material body. Due to the vertical arrangement, it is possible to leave the cavity open on its upper and / or lower base, so that insulating material can be introduced through one of these openings.
  • the polygonal design of the cavity or the brick walls forming it further improves the effect of reduced longitudinal sound conduction, since the structure has a stiffening effect and the wall is therefore less prone to resonance effects.
  • the side lengths of the cross-section differ by a factor of approx. 0.5 to 1.
  • honeycomb shape that is to say an octagonal cross-section, has proven particularly advantageous for the shape of the cavities.
  • the insulating material body preferably comprises a foam-like insulating material which can be poured into a cavity in the brick in a pourable, in particular liquid or semi-liquid, state. In this way, the corners are well filled and the insulating material can then dry or harden, whereby it can also remain elastic.
  • pourable granules in particular mineral granules, can also be filled into the brick as insulating material.
  • the granulate can be made at least partially from mineral fibers such as glass or rock wool, or from perlites.
  • a binding agent such as water glass, can be added to stabilize the granulate.
  • the filling of cavities in the brick with pourable materials is particularly simple, quick and can be carried out simultaneously with a corresponding nozzle arrangement of a filling system for many cavities.
  • Such insulating material is particularly suitable for filling out polygonal structures without having to be laboriously pre-cut and then inserted.
  • the multiple cavities have the same internal volume. It takes the same time to fill all cavities with pourable material. This makes it possible to enable a particularly efficient and possibly automated production process, which can also include, for example, filling the cavities with mineral foam, since the mixing and filling of mineral foam cannot be easily interrupted, but should always remain in flux. In particular, the simultaneous filling of the cavities of several structurally identical bricks is possible.
  • the multiple cavities viewed in cross section, have different edge lengths and / or different arrangements of edges of the same length.
  • all cavities can be adapted to different requirements.
  • the position in the brick, in the middle or on the edge, and the available space can be taken into account.
  • the thickness of the central webs between the cavities can be controlled in order to optimize the stability of the brick, but the polygonal shape with the advantages described above is retained.
  • the joining surface has an open receptacle in which a cutting, in particular a cutting made of elastically deformable insulating material, can be introduced.
  • the cutting can partially protrude from the brick and be in contact with the neighboring brick of the wall.
  • the heat and sound insulation is also guaranteed at the butt joints of the bricks.
  • the open receptacle has an undercut.
  • the open receptacle can, for example, have a dovetail shape, with the wider part pointing into the interior of the brick. With a corresponding shape of the cutting it is secured against falling out. In this way, the brick can be completely manufactured before the wall is transported and built.
  • a cover is arranged on the top of the brick, which covers the one or more vertically arranged insulating material bodies.
  • the cover can be formed in one piece with the brick. The result is a closed bed joint and an application of mortar is possible.
  • the brick can be filled with insulating material be rotated or are already upside down from a previous production step, so that the cover is arranged at the bottom. In this way, the insulation material can be filled in without sticking to the support surface.
  • the stone outer walls comprise a mineral material and / or concrete. This ensures sufficient strength.
  • the insulating material that flows during filling then hardens or dries out in the cavity, although it can remain elastic.
  • This formation of a volume-stable foam material can be set in motion by mixing two or more components shortly before filling. After hardening, the brick can also be turned upside down, with the insulating material remaining in the cavity. The filled bricks can then be transported to a construction site and processed there.
  • the several vertically arranged cavities are expediently filled with the same volume of foam-like insulating material. This enables cavities to be filled at the same time, for which the same time is required for each cavity, so that an equally rapid flow of material can take place in all hose lines and nozzles. This avoids interruptions in the flow of material in the lines, so that the material always remains in a workable state, especially if chemical processes for curing have already been started.
  • a brick is provided with a cover on its upper side that closes the vertical hollow space or spaces, and the provision of the brick includes its underside facing upwards.
  • This provision can be done upside down either by turning the brick, or the brick was already manufactured in this orientation in the previous production step, for example the casting of the brick.
  • the insulation material can be filled into a cavity closed at the bottom, without sticking to the support surface. After drying, the stone can be turned again so that when a wall is built, the cover located on top forms a closed bed joint for the application of mortar.
  • a filling amount of the foam-like insulating material when filling the cavity or cavities is controlled by a dwell time of the brick under a filling system, the foam-like insulating material flowing continuously from the filling system.
  • interrupting the flow of material in the feed line would change the technical properties of the foam.
  • a prefabricated cutting made of insulating material in particular a cutting made of elastically deformable insulating material, is preferably introduced into a receptacle formed on a lateral joining surface of the brick. In this way, insulation is also ensured at the butt joint of two bricks when the bricks are placed next to one another and they clamp the cuttings between them and / or the cuttings are also pushed into the receptacles of the adjacent brick.
  • the cuttings can be introduced into the first brick in the production plant and the complete brick with all insulation materials can then be brought to the construction site.
  • the foam-like insulating material is at least partially in the liquid state during filling and changes to the foam-like state after or during filling. This enables the cavities in the brick to be filled quickly, as the higher material density means that the insulation material can be transported more quickly through the supply lines. In the brick, the insulation material can continue to foam and harden. For example, the density of the foam can be reduced by half.
  • Figure 1 shows a bottom view of a first embodiment of a brick 1, which, enclosed by brick outer walls 2, has five cavities 3 in, in the bottom view or in cross section shown here, an octagonal honeycomb shape in the brick interior 4.
  • Two of the stone outer walls 2 are designed as lateral joining surfaces 7 and have receptacles 5.
  • a body of insulating material 9 is shown in each of the central and side cavities 3.
  • the Figures 1 to 3 Not shown in all cavities 3 insulation material body 9.
  • the insulating material bodies 9 adapt to their shape and thus have eight cross-sectional corners 12.
  • the cavities 3 have side surfaces or, seen in cross section, edges 11 a, b, c, which in this example have different edge lengths L a , L b , L c .
  • the middle cavity 3 again has different dimensions compared to the four further outwardly arranged cavities 3.
  • all edge lengths L a , L b , L c of a cavity 3 can also be the same and all cavities 3 can have the same dimensions.
  • it is advantageous for the filling process if, despite the different dimensions of the side surfaces 11 a, b, c, all of the cavities 3 have the same volume.
  • a cutting 13 made of insulating material is introduced in the left side receptacle 5.
  • the cutting 13 comes into contact with an adjacent brick 1 or a cutting present there when building a wall, so that the butt joint of the two bricks 1 is sealed.
  • a cutting 13 it is also possible, when assembling a wall, for a cutting 13 to be additionally received in the lateral receptacles 5 of the adjoining joining surface 7 of the adjacent brick 1.
  • Lateral elevations 15 and depressions 17 can be provided for aligning the bricks 1 with one another.
  • the Cavities 3, the insulating material bodies 9, the lateral receptacles 5 and the cuttings 13 expediently extend from the underside 19 shown here to the top of the brick 1, but can each extend only over part of the height of the brick 1.
  • Figure 2 shows a bottom view of a second embodiment of a brick 1 with five cavities 3 and a receptacle 5 each in the lateral joining surfaces 7, the receptacles 5 having an undercut 21.
  • the undercut 21 has a dovetail shape.
  • a cutting 13 which is cut accordingly, can be inserted in the vertical direction and the cutting 13 is prevented from falling out to the side, even when the brick 1 is moved.
  • other forms of an undercut 21 are also expedient, which are wider in the direction of the brick interior 4 than on the outside of the opening 5.
  • Figure 3 shows a bottom view of a third embodiment of a brick 1 with eight cavities 3, two in a middle row and three each in an outer row.
  • the two cavities 3 of the middle row have a longer side surface 11 a (here edge shown in the transverse direction) and a shorter side surface 11 c (here edge shown in the longitudinal direction) than the corresponding side surfaces 11 a, b of the cavities 3 of the outer rows on.
  • the side surfaces 11 a, b, c of a cavity 3 can each be different from those of another cavity 3, but the volume of the cavities 3 can advantageously be the same.
  • Figure 4 shows a perspective side view of a brick 1 of a fourth embodiment.
  • the brick 1 is shown rotated with its underside 19 upwards.
  • a cover 25, which closes the cavities 3, is arranged on its upper side 23.
  • the other properties of the brick 1, that is to say, for example, the number, size, shape and arrangement of the cavities 3 can correspond to those of the embodiments described above or also differ from them.
  • the cover 25 can be manufactured in one piece with the rest of the brick 1, for example by casting from a concrete-like material.
  • the lateral receptacle 5 and the lateral elevation 15 and recess 17 can extend over the entire height of the brick 1 or can be shorter.
  • Insulating material in a partially liquid or pourable state can be filled into the cavities 3 at the same time by means of lines 27 of a filling system 29. After the insulation material has solidified in the cavities 3, the brick 1 can be rotated so that the cover 25 is at the top and forms a support for the application of mortar for the construction of a wall.
  • a method for producing a brick 1 is described in more detail below with reference to the figures.
  • the brick 1 is placed under the filling system 29 so that the lines 27 are arranged above one or more vertical cavities 3, depending on the design of the brick 1. It makes sense to place several bricks 1 next to one another, for example in three rows with 4 bricks each. Then the brick or bricks 1 are filled with foam-like insulating material by means of the filling system 29.
  • all cavities 3 have the same volume, so that the same time is required for filling and the material properties of the insulating material are the same everywhere or make the same changes over time.
  • the brick 1 is designed with a cover 25 on its upper side 23, it is provided with its lower side 19 facing upward before filling, as in FIG Figure 4 shown.
  • This upside-down arrangement of the brick 1 results either from a previous production step, for example the casting of the brick 1 in this orientation, or the brick 1 can be rotated accordingly.
  • the insulating material can be filled into the open cavities 3.
  • the brick 1 can be rotated so that its top 23 with the cover 25 is at the top.
  • the brick 1 can be placed on a pallet and delivered and is already in the correct orientation as it is processed by a bricklayer.
  • the foam-like insulating material preferably flows continuously out of the filling system 29 and the filling quantity of the insulating material is controlled via the length of time the brick 1 remains under the filling system 29.
  • a cutting of insulating material is preferably introduced into the lateral receptacle 5 of the joining surface 7 before, during or after the cavities 3 are filled.
  • the foam-like insulating material is at least partially in the liquid state during filling and can thus be transported through the lines 27 of the filling system 29. Even during filling or afterwards in the cavity 3, the insulating material changes to the completely foam-like state or dries and at least partially hardens, but can remain elastic in the process.
  • the cavities 3 can also be other than the polygonal shapes shown, for example one have a twelve-sided shape. It is also possible here for different shapes of cavities 3, in particular polygons with a different number of cross-sectional corners 14, to be present within a brick 1. Other shapes, for example a circular cylinder shape, can also be present in addition.
