    Description: The invention relates to an installation box for electrical purposes, in particular for receiving electronic parts such as switches, sockets, lamps or the like, which are suitable for use in concrete construction.
    A formwork disposed at a certain distance to a steel reinforcement forms the basic shape for a concrete wall to be cast. A precise positioning of the installation box with respect to the formwork is usually carried out by an attachment to the steel reinforcement and a support against the formwork. The attachment to the reinforcement is usually done by a Verrödeln with wire or by clamping the box by means of a clamping device on the steel grid. Corresponding cans are known from the prior art.
    EP 2 375 522 was published in 2012 in the name of the company Kaiser GmbH and relates to an installation box for electrical purposes, in particular for receiving electrical parts in concrete. The installation box has holding parts by means of which the installation box can be attached to a steel reinforcement. The attachment can be done without a Verrödeln. A clamping bar serves for clamping on a steel reinforcement.
    EP 2 804 277 was published in 2014 in the name of the same Applicant and relates to a flush box with a housing having a bottom and at least one side wall adjoining the bottom laterally. At least one laterally projecting from the flush-mounted box holding element is used to attach the flush-mounted box to a reinforcement. A coupling agent serves for the operative connection of the at least one retaining element.
    EP 2 947 734 was published in 2015 on behalf of the company Günther Speisberg GmbH and is about an electrical installation device for concrete construction. The electrical installation device has an installation body and at least one fastening device. The fastening device is designed such that it can be fastened to a reinforcement of the concrete component. It is provided that the fastening device has at least two clamping legs, which protrude from the installation body and thereby extend in two mutually different planes, so that they form a clamping space between each other. The device has no means for exact positioning.
    An installation box must usually be designed so that it can be arranged between the steel reinforcement and the formwork and that after the casting and curing of the concrete, the interior of the can with little effort for further installation freely accessible and by the hardened concrete is not affected. In particular, it must be reliably avoided that concrete flows between the can and the formwork, resulting in sticking and inaccurate contours. After the concrete has hardened, the formwork is removed. An outwardly directed can opening must then be freely accessible again for further installation with the least possible effort.
    A disadvantage of the known from the prior art doses is that they allow in the cast state no optimal design of the edge contours in the region of the outward opening. This is usually due to the fact that the seal between the can edge and the formwork is not sufficiently available so that concrete can penetrate at least partially under them.
    An object of the invention is to show an installation box, which avoids the known from the prior art disadvantages.
    A variant of the installation box for use in concrete construction has a main body surrounding a cavity (installation space). The main body has at least one open end with an opening bounded by a can wall. The opening can be closed by a lid. In the region of the opening, at least one fastening means is provided, which is arranged within a projecting from the can wall projection. As a rule, the projection is directed outwardly from the wall of the can. The lid has a cover member which in the closed state, i. when the lid closes the opening, serves to cover the at least one fastening means, so that the fastening means is protected from penetrating concrete. The fastener is, for example, blind holes or the like. The lid may have first and second sides. The first side may include one or more spacers protruding beyond the first side. In this case, the at least one cover element is advantageously arranged in the region of the second side. The at least one cover element can be operatively connected to the cover via a predetermined breaking point, so that it can be detached from the cover if necessary. The at least one attachment means may be recessed relative to an orifice plane which abuts an opening of the main body such that the at least one cover member rests against at least one underlying ledge when the cover closes the opening. The paragraph may be offset so far from the mouth plane to the rear, that the lid in the installed state and with the second side attached to the outside, completely below the mouth level comes to rest. In order to achieve a better sealing effect and / or more pronounced edge contours, the at least one fastening means can be outlined to the outer edges of the can from a peripheral edge, which later influences the visible contour. The peripheral edge is advantageously designed so that it rests sealingly in the assembled state of the installation box on the formwork for the concrete. If desired, the peripheral edge may be wholly or partly made of a more easily deformable material, e.g. a softer plastic compared to the material of the main body. The peripheral edge may be configured as a separate part or molded on the main body by multi-component injection molding.
    In the case that the peripheral edge is designed as a separate part, this can be operatively connected to the main body by gluing and / or welding and / or via a snap connection.
    The attachment means of the main body are usually within convex protrusions, which depart from the outer contour of the main body. In a preferred variant, the cover elements are designed as tabs, which cover the fastening means in the mounted state. The lid may alternatively or in addition to the at least one spacer on the first side have a highlighted part. This is advantageously at least as high as the at least one spacer. The lid may itself have one or more circumferential edges on one or both sides, which in the assembled state support or seal against the formwork.
    The highlighted part generally has a predetermined breaking point, which allows a breakthrough in the interior of the installation box. The breakthrough can be used for passing cables or for receiving or mounting an electrical part.
    If necessary, the lid may have operative connection means which can detachably connect the lid to the main body of the installation box. The main body may have a second open end suitable for receiving a lid. The second open end is typically located with respect to the can body opposite the first open end. To attach the can to a reinforcement of the can body may have at least one laterally projecting attachment web.
    When the cover is attached to the second side to the outside, the penetration of concrete can be further complicated by the fastening means in relation to the mouth plane, which abuts adjacent to the plane of the later Hilfsbewandung and the opening of the main body of the box, in a deeper level in the box are set back. As a result, the cover elements of the lid come to lie deeper in the can and are better protected by the so-forming peripheral edge of the can. Thus, the bearing surface on which the cover elements of the lid come to lie on the fastening means of the box, not directly adjacent to areas where later concrete is present. It should be noted here that a clean edge between the concrete and the can is achieved by sunk the lid into the can so far that the lid when installed with its outer surface is at the same height as the surface of the can, which on the Hilfsbewandung comes to rest. In any case, however, the lid should be sunk in so far that the can can rest and is not disturbed by the presence of the lid. This is only possible if the lid lies with its outside directly on or below the mouth level and thus deeper in the can. To remove the lid, it may also be helpful if the lid on the second side has at least one tool opening into which the installer can insert, for example, a tool such as a screwdriver and thus can more easily detach the lid from the main body. The tool openings can be arranged in the lid and / or in the main body of the installation box. The tool opening in the main body can either be connected to the installation space or configured separately. In a variant, where the tool opening is formed by a cutout in the lid and in the main body, these are aligned in the mounted state to each other. The cutout in the lid is designed with advantage throughout. Depending on how the fastening means are integrally formed on the installation box, the cover must either have convex over its outer contour integrally formed tab-like covering areas or the fastening means are positioned so that the lid has concave from the outer contour of the lid outgoing cover elements. In both cases, these areas must be sheared off when the lid is attached with the first side out.
    If the lid is attached to the first side to the outside, the entire cover should not be removed later. Therefore, in this case, it is no longer crucial whether the fasteners are glued to concrete. The purpose of incorporating the lid in this direction is to allow for later opening into the can interior, which is significantly smaller than the opening created when the lid is removed and the entire can is open at one end. This is for example advantageous if you only want to lead out of the wall cables for the power supply of lamps. To realize this, concrete must be poured around the can so that, with the exception of the later smaller opening, it is not visible from the outside. This is technically implemented by spacers and highlighted parts on the first side of the lid. These parts rest against the auxiliary surface at the end face and ensure that the resulting gaps can be filled with concrete. The lid may, if desired, be provided on the side of the spacers with one or more reinforcing elements, e.g. in the form of one or more ribs or undercuts, which have a stabilizing effect on the surrounding concrete in this area. In one embodiment, the highlighted part of the lid may have a round basic shape, at the upper circular edge of which a predetermined breaking point is positioned. Thus, the entire round area, which protrudes from the concrete can be broken out, so that access to the installation box is created.
    Alternatively or additionally, the installation box described above can also be installed in an outbreak of an already standing wall. For this purpose, instead of the fastening webs, an assembly tool, such as a mounting rail can be used. One or more installation boxes can be attached to such a mounting rail and thus be positioned freely in the space of a wall breakout and on the surface of the later wall. The mounting rail is in this case on advantage of the surface of the wall, runs over the wall breakout and thus covers this at least partially. At the back of the mounting rail and projecting into the wall outbreak is at least one installation box attached thereto, which is thus positioned in the wall outbreak for cementing, respectively plastering. The mounting of the installation boxes on the mounting rail can be done via multiple mounting elements, which are attached to the mounting rail. The mounting elements can for this purpose engage in openings provided for the lid and / or lock. The mounting elements may alternatively or additionally be designed so that they are designed tapering at its end, so that they at least partially penetrate into the installation box and thus anchored there at least temporarily. Advantageously, engage the mounting elements in the existing tool openings and / or lock and / or anchored there. If the lid also has protruding elements, such as display means for visually indicating the position of a concealed, built-in and plastered installation box, the mounting rail can provide for this cutouts, so that the display means protrude from the wall breakout and over the surface of the wall.
    The invention will be described in more detail below with reference to an embodiment. Show it:

    Fig. 1 shows a first embodiment of an installation box 1 which fastening means 3 has. The fastening means 3 are located at four opposite corners within convex protrusions which project from the outer contour of the main body 11. The fastening means comprise in this case per projection in each case a plurality of blind holes for receiving screws, but may also have a different number of holes. These holes are not continuous to protect the holes on the back from the ingress of concrete. Furthermore, the surfaces 19 from which the attachment means 3 exit vertically offset in the z-direction from the mouth plane 20 of the opening to the rear, so that it concludes with an attached cover 2, preferably mature with the edge of the opening of the main body 11, are actively closed. An embodiment of a corresponding cover 2 and its embodiment will be described in more detail below. Outwardly, the fasteners 3, and the surfaces 19, protected by a peripheral edge 24, which can serve as a support against a formwork (not shown in detail). Advantageously, the edge forms part of a sealing system and thus actively prevents the penetration of concrete into the region of the fastening means 3 or the can interior 25. The embodiment described here has the advantage that a later break-out edge of the concrete also in the area of the fastening means 3 very precise and therefore less frayed and - in contrast to the prior art - forms a clean final edge for further assembly. Also, this arrangement prevents the settling of concrete on the surface 19 between the cover members 4 of the lid 2 and a support surface 19 on the main body 11 where the attachment means 3 are positioned.
    Furthermore, the installation box 1 grooves 21,22, which serve to insert the lid. These grooves may be formed either entirely 21 or only partially 22 by the Bewandung of the main body 11. The end of the grooves 21,22 defines the depth of how far the cover 2 can be sunk into the maximum installation box 1. This depth is defined in such a way that at the same time the cover elements 4 of the cover 2 on the surface 19 of the main body 11, where the fastening means 3 are positioned, rest.
    2 and 3 show the first 9 and second side 10 of a lid 2. The cover 2 can, depending on the field of application, either with the first side 9 to the outside or with the second side 10 to the outside with an opening 27th of the main body 11 are operatively connected. When the second side 10 faces outwards, the cover elements 4 lie on the surface 19 and thus cover both the fastening means 3 and the inner region of the main body 11 from incoming concrete. In the embodiment shown here, the cover elements 4 have the form of convex, thin-walled tabs which protrude diagonally from the cover 2 at four opposite points. Another arrangement is possible. This number and position of the cover (tabs) 4 on the lid 2 corresponds to the number and position of the fastener 3 on the main body 11, or the support surfaces 19. However, it is also conceivable that the fastening means 3 of the main body 11 convex in the Interior of the opening of the main body 11 protrude and the cover 4 are therefore integrated into the lid 2 and have no shape of tabs.
    If the cover 2, as shown in Fig. 4, attached to the first side 9 to the outside, provide in the embodiment shown predetermined breaking points 29 for the shearing off of the cover 4, so that the cover 2 in this position to the end the grooves 21,22 can be inserted and closes the cavity so tight. The assembly of the lid 2 is schematically represented by a first dot-dash line 33. The shearing off of the cover elements 4 is represented by the second dot-dash line 34.
    For the above case, that the fastening means 3 on the main body 11 project convexly into the interior of the opening of the main body 11, the cover 4 are integrated into the lid 2, and these can be broken by predetermined breaking points 29 from the lid 2, when the lid 2 with the first side 9 is attached to the outside.
    If the installation box with the first page 9 attached to the outside behind a formwork and poured with concrete, concrete thus passes between the lid 2 and the Formwork and only the highlighted part 7 is free after removing the training. This has a partition 32, which is operatively connected via a predetermined breaking point 29 'with the cover 2. The partition wall 32 can be cut out so that an opening into the interior of the installation box 1 results. The opening may be used to pass a cable or to mount an electrical part. Other applications are possible. This has the advantage that a smaller hole than the opening of the skin body 11 is created, that later can be easily concealed. An application example for this would be the execution of cables from the ceiling for a later lamp installation.
    The object of the spacer 6, it is here by support points for the formwork to avoid misalignment of the cover 2, and the installation box 1 and to ensure a uniform lowering of the lid 2 in the box 1. The spacers 6 have a triangular shape in this embodiment, so that they taper off of the can 1 away. Also, the height of the spacers 6 in the illustrated embodiment is less than the height of the highlighted portion 7. In this way, the spacers 6 in the concreted state are not or only slightly visible. Likewise, in the event of accidental concreting in of an inclined cover 2, it is ensured that the spacers 6 are only visible from outside at a point.
    As shown in Fig. 4, the installation box 1 at the opposite second end of the skin body 11 may have a further opening 27, so that both openings are parallel and opposite each other. This can be seen in Fig. 4 in the plan view of the installation box 1 each without cover 2: An advantage of this design is that the interior of the box 1 is designed accessible from the front and from the rear, allowing the attachment of installations in the box facilitated concreting. Two covers 2 of an embodiment shown in FIGS. 2 and 3 can now be applied to both openings. In this case, either the first 9 or the second side 10 of the lid 2 can point outwards in each case. The predetermined breaking hole 29 'of the cover 2 can be broken open in a side facing away from the formwork, for example by Cable, hoses from behind into the can 1 feed. If the lid 2 is attached with its second side 10 to the outside, it is alternatively or additionally possible to provide additional tool openings 31, which facilitate the subsequent removal of the lid 2 from the main body 11.
    These tool openings 31 can also be used to attach the main body 11 to a mounting rail 35. In this embodiment, the main body 11 has no attachment webs 12. An embodiment of the installation box 1 without fastening webs 12 is shown in FIG. 5. Also in this embodiment, fastening means 3 are present at four opposite corners within convex projections which protrude from the outer contour of the main body 11. In the variant shown, a cover 2 is mounted with its second side 10 to the outside. On the second side 10 are at the respective opposite corners tool openings 31. As seen in the detail view of Fig. 5, the tool opening 31 is formed by a cutout in the lid 31 a and a cutout 31 b in a side wall of the installation box 1. Furthermore, the thus formed tool opening 31 is configured separately from the installation space. It can also be seen that a bottom 39 of the tool opening is made thin-walled. The installation box 1 shown further comprises a display means 36 on the second side of the lid 10. The display means 36 may be used to facilitate a fitter locating an in-wall installation box 1 after plastering.
    To position the installation box 1 on a mounting rail 35 in a wall breakout (not shown), for example, the mounting rail 35 is secured to the left and right of a wall breakout on the wall (e.g., by screws). At the back of the mounting rail 35 at least one installation box 1 is fixed, which is positioned in the space of the wall outbreak. Subsequently, the so-positioned installation box 1 can be cemented or plastered. After curing, the mounting rail 35 is removed while the installation box 1 remains in the masonry. Fig. 6 illustrates a mounting rail 35 with a total of three installation boxes 1, which are attached to it. Another number of attachable installation boxes 1 is also conceivable. The attachment via mounting elements 37, which are attached to the mounting rail 35. The mounting elements 37 engage in the case shown in the tool openings 31 of the installation box 1 a. Here, the installation boxes 1 are attached to the mounting rail 35, that the respective installation box 1 are first placed with the tool openings 31 on the mounting members 37. The mounting elements 37, which are designed tapering at its end, are then pressed into the tool openings 31, where they penetrate the thin-walled bottom 39 of the tool openings 31 and thus anchored there at least temporarily.
    It can be seen that the tapered mounting elements 37 of the mounting rail 35 below the thin-walled bottom 39 of the tool openings 31 again from the installation box. 1 emerge and are thus visible. However, it is also conceivable to design the mounting elements 37 such that they do not emerge from the installation box 1 in the fastened state of the installation box 1 on the mounting rail 35. The latter has the advantage that the mounting elements 37 does not come into contact with gypsum and / or cement. It can also be seen in FIGS. 6 and 7 that further cutouts 38 are provided in the mounting rail 35, through which the display means 36 of the installation box 1 can protrude and a fitter after installation of the installation boxes 1 and after removal of the mounting rail 35 exact location of the built-in and externally plastered installation boxes 1 visually clarified.
