    description
    The invention relates to a connection between wall elements of prefabricated buildings. " prefabricated buildings " For the purposes of this document, buildings are those in which flat wall elements are prefabricated without being connected to other wall elements and then suitably placed in one piece at the construction site and connected to adjacent wall elements.
    There is a plethora of suggestions for a second Wandelementbzw. connecting a comparable element to an adjacent first element by projecting parts obliquely downwardly away from the second element, and in each case a corresponding part of the first element from below into the downwardly open groove or bay between the second element and the one of the ¬sem obliquely down projecting projecting parts. In this way, entanglements are formed between the two elements, with the hooks on the first element open at the top and the hooks on the second element open at the bottom. For the manufacture of the connection, first the first element is placed in the appropriate position on the ground and then the second element is introduced obliquely from above, so that the entanglements intermesh. By gravity, the elements remain fixed to each other. By dimensioning and orientation of the entanglements, it is achievable that the elements are pulled into each other in a precisely defined relative position and remain fixed to one another. In the example of wall elements of prefabricated buildings, the hooking parts of the wall elements are already preassembled in the factory then be fixed to each other at the construction site quite quickly. To literature examples are to be called:
    According to CH 249576 A, two wood profiles, which are arranged between adjacent wall elements and pinch projections on the end faces of the wall elements, are pulled together by the entanglement described above. The entanglement pulls the two wood profiles horizontally towards one another in the direction normal to the wall plane. At the Verhakungliegen two metal parts, which are connected to each one of the Holzprofiled by screws to each other. DE 1980373 U shows a Verhakung of the type described by which wall elements in the common wall plane in the horizontal direction are pulled together. The hooked parts are on one side of a metallic edge profile of the second Wandele¬ments punched and bent tongues, on the other hand, the respective lower edge regions of openings on a metallic edge profile of the first wall element. Very similar proposals show the DE 3820684 Al, US 3087586 A and also WO9533898 Al.
    According to EP 1718812 Bl, the entanglement is formed by pairs of complementary sheet metal bent parts, the parts of the pair being fastened to different, mutually facing, grooved end faces of different wall elements. The mutually complementary bent sheet metal parts each have a plurality of pairs of mutually identically aligned contact surfaces against which the bent sheet metal parts interlock with one another. The different pairs of Berüh¬rungsflächen are not aligned parallel to each other. In order to ensure that the wall elements are guided in the horizontal plane both parallel to the common wall surface to be formed and also in the appropriate relative position relative to each other.
    The object underlying the invention is to provide a novel connection for wall elements of Eertigteilhäusern, through which a second wall element can be fixed to a first, already erected Wan¬delement by the second wall element in relation to the first wall element raised Zu¬stand to the first wall element is brought so that the bei¬ the wall elements touch each other at the two intended Berüh¬rungsflächen and then the second wall element is lowered to the same height as the first wall element.
    Compared with the solutions already known from the prior art, the new connection should be better in that - the wall elements do not have to be guided so precisely during assembly - the connection is less sensitive to manufacturing tolerances, in particular to deviations of dimensions of individual parts from those theoretical ideal dimensions.
    The problem solving according to the invention is achieved by the combination of the following features: a) In each of the two wall elements to be connected, a respective surface facing each other wall element is provided, further as " connection profile " marked - profile fix anchored. b) The two connection profiles lie with one each - the other as " clamping surface " surface area on a clamping surface of the other connecting profile, each clamping surface enclosing an acute angle with that surface of the wall element which is connected to the connecting profile. c) At least one of the two connection profiles has a groove into which a profile wall of the other connection profile protrudes. d) In the connecting profile having a groove, there is a clamping surface on the groove-facing side of a profile wall laterally delimiting the groove. e) The width of the groove on the one connecting profile is greater than the width of the protruding into this groove profile wall of the other connection profile. The remaining width range is bridged by blocks, which are each fixedly connected to one of the two connection profiles. f) A block has an inclined surface, which faces away from the block of each surface of the connection profile with which the block is connected, and forms an acute angle with the profile direction of the connection profile.
    The invention will be illustrated by way of somewhat stylized drawings for exemplary embodiments:
    1 shows a horizontal sectional view through the connecting region of two wall elements, which according to the invention are connected to one another on two mutually facing vertical end faces. Parts which are hatched in the same direction are fixedly connected to one another.

    3 shows a top view of a further example of a connecting region of two wall elements, which according to the invention are connected to one another on two mutually facing vertical end faces.
    FIG. 4: shows a vertical sectional view of the two wall elements of FIG. 3 during assembly, the sectional plane being that indicated in FIG. 3. Parts which are hatched in the same direction are fixed together.
    5 shows, in a top view, a third example of a connecting region of two wall elements, which according to the invention are connected to one another on two mutually facing vertical end faces.
    Fig. 6t shows the wall elements of Fig. 5 separated in a perspective view. The wall element 2 shown above is indicated for joining according to the invention with the wall element 1 shown below, as indicated by the dotted curved arrow, to pivot through 180 °.
    7 shows, in a vertical sectional view through connected wall elements according to the invention, an optionally applicable invention detail. Parts which are shown hatched in the same direction are fixed to each other.
    In the example according to FIG. 1 and FIG. 2, the wall element 1 is provided with a vertical vertical wall surface facing the wall element 2 with a connecting profile 3 extending along this end surface. The wall element 2 is provided on its vertical, the Wan¬delement 1 facing end face with a connecting edge 4 extending along this end face. The Wan¬delemente can for example consist of glued together wooden planks. The connection profiles 3, 4 are typically wood profiles. The connection between wall element 1, 2 and jewei¬ligem connecting profile 3 4 is rigid and ideally prefabricated fab¬rikseitig already. Typically, this rigid connection is formed by gluing and additional screws.
    The connection profile 3 rigidly connected to the wall element 1 has a profile groove open toward the wall element 2. The connecting profile 4 aligned parallel to the connection profile 3 projects from the wall element 2 into the profile groove on the connection profile 3 and is surrounded on three sides by the profile groove. In the direction normal to the plane of the wall elements 1, 2, the connection profile 4 is narrower than the groove on the connection profile 3 and also narrower than the opening width of this profile groove. The " included " Connection profile 4 lies with two lateral surface sides at boundary surfaces of the groove in the " comprehensive " Connection profile 3an. The lateral surface side of the connection profile 4 facing away from the wall element 2 bears against the base surface of the groove in the connection profile 3.
    One further as " Clamp 4.1 " designated lateral surface of the connection profile 4, is located at one of the further as " clamping surface 3.1 " designated surface of the connection profile 3an, which is the inside of a, the groove on the connection profile 3begrenzenden, side profile wall. The clamping surfaces 3.1, 4.1 are arranged parallel to each other and abut each other. Of essential importance is that the clamping surfaces 3.1 and 4.1 with their facing surface of belonging to them Wan¬delements 1 and 2 each include an acute angle a.
    In each case at the ends of the connection profiles 3, 4, a block 5neben the connection profile 4 in the groove in the connection profile 3, which bridges the difference of the width of the groove to the Brei¬te the connection profile 4 exactly. Since the blocks 5 are arranged on the side of the connecting profile 4 facing away from the clamping surfaces 3.1, 4.1 in the groove in the connecting profile 3, they force the clamping surfaces 3.1, 4.1 to rest against one another. The blocks 5 are typically made of wood; Ideally, their width is such that they are slightly compressed in the groove between the two connecting profiles in the elastic region and thus caused by elastic bias a force on the connecting profile 4, through which this in the normal direction to the profile plane with its Klemm¬ surface 4.1 is pressed against the clamping surface 3.1 of the connection profile 3.
    In that the clamping surface 3.1 of the connection profile 3 encloses the acute profile a with the surface of the wall element 1 connected to the connection profile 3 and the clamping surface 4.1 of the connection profile 4 with the surface of the connection profile 4 facing the connection profile 4 Wall element 2 encloses the pointed Win¬kel a, by pressing together the two
    Clamping 3.1, 4.1, the two wall elements 1, 2 pulled against each other until the connection profile 4 rests against the base of the Nutim connection profile 3 and / or until the wall element 2 facing surfaces of the connection profile 3 abut the wall element 2. This results in a clearly defined, well-fixed position of the two wall elements 1, 2 to each other.
    The more detailed arrangement of the blocks 5 and the mounting operation of two wall elements 1, 2 together will be apparent from Fig. 2 (and further with reference to Figs. 4 and 6).
    The wall element 1, which has the connection profile 3 is placed on the construction site as the first of the two wall elements 1, 2 a match. At the lower end of the groove in the connection profile 3, a block 5 is fixed, typically by being bolted to the connection profile 3 with countersunk screws. This unte¬re log 5 has a clamping surface 5.1, with which he is determinant in accordance with the completion of the assembly on the connection profile 4 an¬liegt and presses against this. Furthermore, the lower block 5 has an oblique surface 5.2, which is oriented such that a horizontal Verschie¬bung is connected to it with decreasing height coordinate, which is spaced from the beabstandet from the connection profile 4 lateral boundary of the groove in the connecting profile 3 to the connection profile. 4 connected is. In the lower log 5, this inclined surface 5.2 is a steep slope surface.
    The wall element 2, which has the connection profile 4 is set up on the construction site as the second of the two wall elements 1, 2 pas¬send. At the upper end of the groove in the connection profile 4, a block 5 is fixed, typically by being bolted to the connection profile 4 with countersunk screws. This upper block 5 has a clamping face 5.1, with which it is in contact with the connecting profile 3 and presses against it after the installation has been completed. Furthermore, the upper block 5 has an oblique surface 5.2, which is oriented such that a horizontal displacement is connected to it with decreasing height coordinate, which differs from the lateral delimitation of the groove in the connection profile 3 to the connection profile 4 from the connection profile 4 connected is. In the upper block 5, this inclined surface 5.2 is a steep overhang surface.
    In the typical installation of the wall element 2 on the already placed wall element 1, only the wall element 2 is raised above the wall element 1 in a raised position relative to the wall element 1 (by means of a crane) so that the lower longitudinal region of the connection profile 4 passes through the upper longitudinal region of the connection profile 3 but the lower block 5 is still entirely below the wall element 2 and the upper block 5 is still entirely above the wall element 1.
    Then the wall element 2 is lowered. The connection profiles 4.3 cause loose guidance of the movement. Towards the end of the lowering, a lower edge region of the connection profile 4 reaches the oblique surface 5.2 of the lower pad 5 and the slanted surface 5.2 of the upper pad 5 reaches an upper edge region of the connecting profile 3. At the inclined surfaces 5.2 slide blocks 5 and connecting profiles 3 and 4, respectively in that the connection profile 4 is positioned relative to the connection profile 3 in the plane normal to the profile direction '' automatically " indie shown in Fig. 1, defined position comes. Finally, the connecting profiles 3, 4 to that end of the oblique surfaces 5.2 of the blocks 5 in which each of the inclined surfaces 5.2 passes into the clamping surface 5.1. Under friction between clamping surfaces 5.1 and connecting profile 4 or connecting profile 3, the wall element 2 still slides down until it rests with its lower end face as already the wall element 1 on the underlying part of the building. Since the connection between the Wan¬delementen 1, 2 with respect to rotation of the wall elements about the verti¬kale axis of the connection is not very stiff, the Wan¬delement 2 should be pivoted about this axis in the correct position before it actually touches the ground.
    It is obvious that this type of assembly can be done very easily and quickly, without the need for large-scale craftsmanship or expensive equipment.
    If necessary (for example, in areas with risk of earthquake), one can additionally connect the wallcovering to the described installation by additional connecting elements such as screws inserted obliquely from the upper end faces.
    In the embodiment according to FIGS. 1 and 2, the construction according to the invention is explained by way of example. 1, and 2, it can be criticized that two different connection profiles 3, 4 have to be used, which may mean a logistical expense compared with the requirement of mutually identical connection profiles. In the construction according to the drawings Fig. 3 to. Fig. 6 is this (possible) disadvantages.
    In the construction according to FIGS. 3 to 6, the two connection profiles 13, 14 or, 23, 24, which are to be coupled with one another, are exactly the same. They are only in the installed position about a profilpa¬rallel axis pivoted to each other by 180 ° and slightly laterally (against the plane of the wall elements to be connected) against each other. The connection profiles 13, 14 and 23, 24 each have a groove and two lateral boundary walls of the groove. When the connection is finished, a respective lateral boundary wall of the one connection profile protrudes into the groove of the respective other connection profile.
    4, the wall element 1 is provided with the connection profile 13 and the wall element 2 with the connection profile 14. The clamping surfaces 13.1, 14.1 which are essential according to the invention are the same as in the case of the clamping surfaces 3, FIG. 1, 4.1 - are respectively on the inside of that seitli¬chen Nutbegrenzungswand of the connection profile 13, 14, which indie groove in each case on the other connection profile. That Breiten¬ area of the two grooves, which is not covered by the protruding into the respective groove profile wall of the respective other connection profile, in turn, by lower and upper blocks 15 {Fig. 4), which are the same in function, structure and arrangement as the blocks 5 according to FIG. 1 and FIG. 2, covered. The blocks 5 each extend between that profile wall of a connecting profile 13, 14, which is encompassed by the groove on the other connection profile 14, 13 on one side and that profile wall on the other connection profile 14, 13, which faces away from the first connection profile is on the other side. This construction implies that two pairs of blocks 15 are required per wall connection, each comprising an upper and a lower block 15.
    5 and 6, the wall element 1 is provided with the connection profile 23 and the wall element 2 with the connection profile 24. The clamping surfaces 23.1, 24.2 and 24.1, 23.2 which are essential in accordance with the invention are the same as in the case of the cleram surfaces 3.1 , 4.1 - lie on the one hand in each case on the outside of the lateral Nutbegrenzungswand the Verbin¬dungsprofils which projects into the groove on the other Verbindungs¬ profile, on the other hand respectively on the inside of that profile wall of a connection profile, which does not protrude'in the groove on the other connection profile , This results in two pairs of adjoining clamping surfaces 23.1, 24.2, or 24.1, 23.2, which are offset from one another laterally (normal to the plane of the wall surfaces). That width region of the two grooves, which is not covered by the profile wall of the respective other connecting profile projecting into the respective groove, is again divided by an upper and a lower block 25 (Fig. 6), which are the same in function, structure and arrangement as the blocks 5 according to FIG. 1 and Fig. 2, covered. The blocks 25 each extend between those two profile walls of the two connecting profiles 23, 24, which are covered by the groove on the respective other connecting profile. This construction requires that each wall connection is made possible with a pair of blocks 25 which, with respect to the wall elements 1, 2, lie exactly in their wall-parallel plane of symmetry.
    Of the three versions shown, the version according to FIG. 5 and FIG. 6 may be the most advantageous with regard to production outlay and static strength.
    In the drawings Fig. 1 to. Fig. 6 each blocks 5,15, 25 were presented, which in each case bridge the gap to be bridged between two connection profiles alone. This requires that these Klöt2e 5, 15, 25 only at the obenbzw. lower end of a connection profile can be arranged, if they do not complicate the assembly to impossible to do. However, this requires that the connection between Wan¬delementen 1, 2 is not fixed well in the middle height and that (over time) there may be gaps.
    In Fig. 7, a construction and Anordnungsweise for blocks 35 sketched by which this disadvantage is recoverable. In each case, a pair of blocks 35 are used which, when the wall elements are finished, are arranged at the same height and juxtaposed against one another and jointly bridge the gap to be bridged between two connecting profiles 3, 4.
    In the example sketched in FIG. 7, the connection profile 3 belongs to that wall element which is placed first. The block 35 connected to the connection profile 3 has its sloping surface like a slope at the top. The connecting profile 4 belongs to that converter, which is set up second and is lowered during installation along the wall element previously parked. The Klotz35 connected to the connection profile 4 has its inclined surface overhang-like at the bottom. When lowering the second wall element, the blocks 35 slide on the two inclined surfaces 35.2 from each other and finally come to the Kienunflächen 35.1 for concern.
    At two wall elements to be connected, a plurality of pairs of blocks 35 may be provided at a vertical distance from each other, where-these pairs may also be arranged remotely from the upper and lower ends of the connection profiles. Above all, for optical reasons, it is advantageous to use one-piece blocks 5, 15, 25, as described above, at the upper and lower ends of the connection profiles.
    In the case of the connection according to the invention, the wall elements always lie on the ground, since adjacent wall elements, with the exception of relative movement with respect to one another, can not be held positively in the vertical direction. Against lateral Rela¬tivbewegung the wall elements are held by Verbindungs¬ profiles and blocks made of wood. Since wood has a relatively low modulus of elasticity (in particular transversely to the fiber direction), connecting profiles and blocks can, when the connection is produced, abut one another well under elastic pretension. This results in a very good balance of custom manufacturing tolerances by elastic deformation of the connecting parts. Due to the already described above Aus¬führung the clamping surfaces and in that the groove in a Ver¬ binding profile, in which a wall of the other Verbindungspro¬fils must be introduced, can be very much wider than the wall, which is also introduced Assembly of Wan¬delementen possible, without that it is difficult to leading precise relative movements of the wall elements to each other. (The required exact relative movements of the wall elements to each other are automatically matched by the type of connection.) Moreover, the connection according to the invention does not cause any annoying cold bridges between the two sides of the wall.
    In addition, it should be mentioned that not only face-face connections between wall elements are possible by the connection according to the invention, but also L and T connections.
    It only depends on which area of a Wandele¬mentes one provides a connection profile.
