    Shuttering system for a luminaire integrated in a concrete wall, a luminaire integrated into a concrete wall and a method for forming a cavity in a concrete wall for receiving a luminaire
    The present invention relates to a shuttering system for a luminaire integrated into a concrete wall, and to a luminaire integrated into a concrete wall and to a method for forming a cavity in a concrete wall for accommodating a luminaire.
    It has long been known to attach hollow body for receiving lamps in a formwork, which is filled with concrete, so that the hollow body define a cavity for receiving lights. By way of example, reference is made to DE 43 12 661 C2, DE 44 03 238 01, EP 0 662 742 B1, DE 195 30 429 C1, DE 198 42 512 C1, DE 10 2006 019 167 B3 and to DE 196 07 254 C2.
    In DE 196 07 254 C2, such a hollow body for concrete construction installation is described, which is approximately hollow cylindrical and has at its rear end a bottom. The front side of the hollow cylindrical body is open and can be closed with a separately formed front part. The front part has a peripheral outer flange whose diameter is slightly larger than that of the cylindrical hollow body.

    Mounting flanges before, which can be attached to a formwork panel. The attached to the formwork panel front part is cast together with the hollow cylindrical body in forming the concrete wall with concrete. When demoulding the concrete wall, the outer flange is torn out of the concrete wall together with the shuttering panel. The result is an annular cavity at the front edge region of the hollow cylindrical body. This annular cavity is filled in a further operation with plaster. Through the plaster, the front edges of the hollow cylindrical body integrated into the concrete wall can be hidden. The plaster is preferably applied so that the transition between the plaster and the concrete is difficult to see.
    From DE 44 02 977 C2 and DE 195 10 819 C2 go hollow body for the electrical installation, in particular for receiving lights out, the corresponding concrete wall is made with a Doppelbetonierverfahren. In this case, first a viewing plate, the wall is concreted, in which predetermined by the hollow body recesses are limited. Thereafter, the back of the wall is concreted.
    DE 10 2006 011 094 A1 discloses a mounting device for receiving a lamp, wherein the mounting device can be installed in a ceiling wall. For this purpose, a hole is made in the top wall, which is large enough to accommodate the mounting device. Thereafter, the ceiling is plastered, wherein the mounting device is formed at its lower edge with a chamfer such that the plaster remains on the chamfer and the front edge of the mounting device is hidden substantially behind the plaster. In an alternative embodiment, a pouring cup is provided which can be poured into a concrete floor. The casserole has a directed to the outer surface of the concrete pavement opening, which is closed during casting in the concrete ceiling by a shuttering. The casing is firmly connected to it by means of a threaded rod which extends to the bottom of the pouring pot.

    To provide a method for forming a cavity in a concrete wall for receiving a lamp, in which a hollow body for receiving the lamp with distance to the visible outer surface of a concrete wall can be arranged without a plastering of the Öffhungsbereiches is necessary.
    The object is achieved by a wall system integrated into a concrete wall luminaire according to claim 1, a concrete wall integrated into a luminaire according to claim 14 and a method for forming a cavity in a concrete wall for receiving a luminaire according to claim 16. Advantageous embodiments of the invention are specified in the respective subclaims.
    An inventive shuttering system for a lamp integrated in a concrete wall comprises - a hollow body for receiving a lamp, wherein the hollow body has an opening, and - a formwork body which is fastened to the hollow body such that it closes the opening, wherein the formwork body of a hard Core and a soft coat is formed.
    A concrete wall according to the present invention comprises a vertical concrete wall, a horizontal ceiling and a wall inclined from the vertical.
    By completing the opening of the hollow body by means of a formwork body with a soft surface can be removed from the concrete wall after pouring the concrete wall of the formwork body without the surface of the concrete wall is damaged. Plastering the opening area is therefore not necessary.
    With such a formwork body, the opening area can be arbitrarily shaped, so that free-formable transition surfaces made of concrete between the opening of the hollow body and the visible outer surface of the concrete wall are created. In particular, it is possible to form in the concrete wall an approximately funnel-shaped widening channel from the opening of the hollow body to the visible outer surface of the concrete wall. The cross-sectional shape of the funnel-shaped channel can be any
    ΦΦΦΦ φ • Φ · side -4- ΑΤ-7095 be made big, in particular straight, parabolic, elliptical. The channel can thus act as a reflector for the light emitted by the light.
    With the formwork body, a channel can be formed, which preferably has a larger opening than the opening of the hollow body in the region of the outer surface of the concrete wall. In particular, it is expedient if the shuttering body is flush with the opening of the hollow body, so that when poured with concrete, the wall of the hollow body in which the opening is mounted, is completely covered by the concrete, so that it is not visible from the outside.
    The Schaiungskörper is preferably formed in two parts, wherein the hard core and the soft shell are formed separately from each other, so that when you len first the hard core can be removed and then the soft shell is removed from the concrete. However, it is also basically possible to remove the covering body as a part comprising the hard core and the sheath during demoulding.
    The hard core of the shuttering body is preferably formed of a hard plastic part or a piece of wood.
    The soft shell is preferably formed of a foam, in particular of a closed-cell foam with a smooth surface. For structuring the concrete surface, the foam may be formed with a structured surface. The foam consists, for example, of polyurethane (PU).
    The hard core substantially defines the shape of the channel. The soft coat allows a simple and clean demoulding. The easy demoulding and the reliable shaping can be ensured if the jacket is softer than the core.
    The soft shell is preferably thin-walled with a thickness in the range of 3 mm to 20 mm, in particular in the range of 3 mm to 15 mm. Such a thin-walled jacket, in particular the form-fitting on the hard core # * * ♦ ···· ft · ** · AT-7095
    Page -5 sits, is compressed during casting with concrete by a defined amount, so that a predetermined desired shape of Betonoberfiäche is achieved. The thinner the wall of the soft shell, the lower the tolerances due to the deformation of the shell by the pressure of the concrete. It has been found that the soft sheath can be very thin, e.g. may have a thickness of 3 mm, and yet the deletion, i. the removal of the hard core and the removal of the soft shell of the cured concrete wall is easily possible.
    The shuttering system has fastening means for fastening the formwork body to the hollow body. These fastening means comprise, for example, a retaining element in the form of a strip or a U-profile whose length is greater than the diameter of the opening and which has at least one threaded bore and preferably at least two threaded bores in order to engage with corresponding threaded screws through through holes in the Formwork body, in particular in the hard core of the formwork body extend to fix the formwork body to the bar. These screws are detachable, so they can be removed for removal. The strip can then be removed through the opening of the hollow body. The formwork body, in particular the hard core of the formwork body, preferably has one or more through openings for receiving in each case a metal pin or nail in order to fasten the formwork body to a formwork panel.
    In a further development of the invention, the holding element is arranged at a distance from the inner surface of the wall of the hollow body, in which the opening is formed. In this way, the tapered formwork body can be pulled a piece into the opening, so that the edge of the opening is sealed flush with the shuttering body and the shuttering body itself does not cover the wall. This ensures that when poured with concrete, the wall is completely covered with concrete and is no longer visible on the finished concrete wall.
    The hollow body is preferably formed in two parts, in particular with a detachable lid, so that during assembly of the formwork system on a Verscha- • 4 ··· «4 ······· · · · 4 · · · · · 4 ·» * »4 ·· 4 * *« «• · 4 · · · · · ·« ATX «. AT-7095
    Side -4- the inner area of the hollow body is freely accessible to fix the formwork body on the hollow body and / or on the formwork panel.
    The hollow body has tabs for adjusting and / or fixing the hollow body to the casing and / or to reinforcing bars. This is particularly advantageous in the case of large hollow bodies to which significant moments act when casting concrete.
    On the hollow body one or more openings for the supply of Elektrolei-lines are formed. The openings are preferably provided with corresponding nozzles to which conduits for electrical cables are placed concrete top.
    A luminaire according to the invention, which is integrated in a concrete wall, comprises: a hollow body cast into the concrete wall, in which a luminous means is arranged, the hollow body having an opening for the exit of light emitted by the luminous means, and an outwardly opening from the opening flaring channel bounded by the concrete of the concrete wall.
    In the luminaire according to the invention, the channel is limited exclusively by the concrete of the concrete wall. As a result, there is a continuous exposed concrete surface which extends from the outer surface of the concrete wall to the opening of the hollow body. The channel widens outwards so that it can serve as a reflector for the light emitted by the light source. The channel is formed in particular funnel-shaped widening.
    The opening of the hollow body is preferably offset from the outer surface of the concrete wall a piece in the concrete wall, wherein the distance between the plane of the outer surface and the opening is preferably at least 15 mm, in particular 20 mm, 25 mm, 30 mm or 35 mm. The length of the formwork body used to form the channel corresponds to this distance. II ·· • Μ * UM · • «*

    The transition between the channel and the outer surface of the concrete wall may be formed by an angled edge. However, it is also possible to round off this transition, so that an edge-free transition between the outer surface of the concrete wall and the channel is formed. 5
    The opening of the hollow body is arranged parallel to the outer surface of the concrete wall. However, the lamp may also be designed such that the opening of the hollow body is inclined relative to the plane of the outer surface of the concrete wall. The invention further relates to a method for forming a cavity in a concrete wall for receiving a luminaire, the method comprising the steps of: a) attaching a formwork body, which has a hard core and a soft shell, to a hollow body, so that an opening the hollow body 15 is covered by the formwork body, b) fixing the formwork body to a formwork with the side facing away from the hollow body, c) pouring out the formwork with concrete, d) removing the formwork, and e) removing the formwork body.
    With this method, a cavity is created in a concrete wall, which is suitable for receiving a lamp and having a channel extending outwardly from the opening of the hollow body, which is delimited exclusively by concrete. With this method, the above-described luminaire integrated into a concrete wall can be manufactured.
    The steps a) and b) can also be carried out in reverse order, that is, that the formwork body is first attached to the component formwork and then the formwork body and the hollow body are connected together.
    The hollow body can additionally be fixed to the component formwork and / or to an iron reinforcement before the component formwork is poured with concrete. · · · · · · · · · · · · · · · ··················································· 7095

    Hereinafter, a first embodiment of the invention will be explained with reference to FIGS 1 to 5. An inventive shuttering system has a hollow body 10 per 1 for receiving a lamp 2 and a two-part formwork body with a hard core 3 and a soft shell 4.
    In the present embodiment, the hollow body 1 is an approximately cuboid body with a bottom wall 5, two Längsseitenwandungen 6 and two Stirnsei-15 tenwandungen 7. The hollow body 1 has a form-fitting deductible cover 8.
    In the bottom wall 5, an opening 9 is formed. In the present embodiment, the opening is circular. In the context of the invention, the opening 20 may of course have other shapes. The opening 9 is used to insert an operating device 10, the lamp 2 and the output of the light emitted by the lamp 2 light.
    On one of the two Stirnseitenwandungen 7 two openings for performing 25 of electrical lines are formed, these openings are each surrounded by a connection piece 11, to each of which an empty tube for carrying out the electrical wiring can be infected concrete. These openings can of course also be formed on the Längsseitenwandungen 6. 30 At the Längsseitenwandungen 6 is in each case a tab 12 for fixing the hollow body 1 attached to an iron reinforcement. The tabs 12 are adjustable in their position so that they can be adjusted to different distances between the iron reinforcement to the hollow body 1.

    The hollow body 1 of this embodiment is approximately cuboid. It may of course be expedient to form the hollow body in any other form, in particular to form so that the lamp 2 and the operating device 10 have space with play, but no superfluous cavity is maintained, since in principle the smallest possible hollow body is preferred on the one hand to keep the weakening of the concrete wall as low as possible and on the other hand to provide the concrete with as little interference resistance as possible when pouring it with concrete.
    The hard core 3 of the shuttering body is composed of two truncated cones, so that it has a slight indentation in the region of its lateral surface. The soft sheath 4 is formed with its inner surface complementary to the lateral surface of the hard core 3, so that the soft sheath 4 is positively seated with some tension on the hard core 3. The outer surface of the soft shell 4 forms a truncated cone with one end of smaller diameter and one end of larger diameter.
    In the hard core 3 are two through holes 13 for receiving threaded screws 14 and four through holes 15, through each of which a metal pin or nail 16 may extend formed.
    The end of the formwork body with a small diameter is slightly larger in the present embodiment than the opening 9 of the hollow body. 1
    On the inside of the bottom wall 5, two pins 17 are integrally formed adjacent to the opening 9.
    A U-profile 18 has a length such that it extends slightly beyond the two pins 17. At the end portions of the U-profile 18 holes are formed so that the U-profile can be set with one hole on one of the two pins 17. The U-Profii has two further holes, which are formed symmetrically to the longitudinal center of the U-profile and spaced at the passage holes 13. * * ··· · ···· ΑΤ-7095
    Side -Il of the hard core 3 for receiving the threaded screws 14 are arranged. Adjacent to these holes in the U-profile in each case a nut 19 is arranged, which is preferably fixedly connected to the U-profile, for example by means of soldering, welding or clamping. These nuts 19 thus form integrally formed with the U-profile 18 threaded holes.
    The assembly of the formwork system and the production of a concrete wall with an integrated luminaire will be explained below with reference to FIGS. 2a to 2r.
    First, the soft shell 4 is arranged on the outside of the bottom wall 5 of the hollow body 1 concentric with the opening 9 (Fig. 2a). In the soft shell 4, the hard core is used (Fig. 2b), wherein the narrower end of the shuttering body rests against the bottom wall 5. Through the through holes 13 of the hard core 3 of the shuttering body respectively a threaded screw 14 are pushed through until anschiagen with their heads on the hard core 3 (Fig. 2c). On the inside of the bottom wall 5, the U-profile 18 is placed, so that the end-side holes of the U-profile 18 are penetrated by the pins 17. The threaded screws 14 are screwed into the nuts 19 of the U-profile 18. As a result, the formwork body is fixed to the hollow body 1 (FIGS. 2d, 2e).
    The unit of formwork body 3, 4 and hollow body 1 is fixed by means of metal pins or nails 16 on a formwork 20, which is usually formed of Holzbrettem or formwork panels. The component formwork should be as free of dirt as possible, so that the formwork body 3, 4 is secured without clearance on the component formwork (Fig. 2f).
    The tabs 12 of the hollow body 1 are pushed so far down until they either on the reinforcing bar 21 or on the formwork 20 are pending (Fig. 2g). Then the tabs 12 are fixed in position by means of corresponding nuts 19.
    Thereafter, conduits 22 are connected to the connection stubs 11 of the hollow body 1 (Fig. 2h). •·············································································································································
    Page 12-
    The hollow body 1 is closed by means of the cover 8 (FIG. 2i). By means of a wire 23, the hollow body 1 can be fastened to the reinforcing iron, whereby an uncontrolled floating up during the concreting process is avoided. The wire is preferably stretched over the cover 8 away, so that an accidental rising of the lid is reliably avoided {Fig. 2y).
    The component shuttering is poured out with concrete 24 (FIG. 2k), the concrete enclosing the shuttering system 1, 3, 4 according to the invention (FIG. 2k). In the figures, the component formwork 20 is shown in each case only on one side, as is usual in ceilings. Of course, in the case of a vertical or inclined wall, the component formwork 20 comprises two approximately parallel shuttering walls. The concrete is cured in the component formwork.
    After curing, the component formwork is first removed from the hardened concrete wall. This results in the drawn in Fig. 2I view in which the formwork body 3, 4 according to the invention in the concrete wall.
    First, the threaded screws 14 are removed, whereby the formwork body 3, 4 is released from the hollow body 1 (Fig. 2m). Thereafter, the formwork body is removed from the concrete wall by first pulling out the hard core 3 and then releasing the soft shell 4 from the surface of the concrete wall (Figure 2n). It is also possible to pull out the entire formwork body consisting of the hard core 3 and the soft shell 4 at a time out.
    Thereafter, the U-profile 18 is lifted from the pins 17 and led out through the opening 9 of the hollow body 1.
    Electrical lines are introduced through the conduits 22, led out of the opening 9 and electrically connected to the operating device 10. To the operating device 10, the lamp 2 is connected. Then, first of all, the operating device 10 is inserted through the opening 9 into the hollow body 1 (FIG. 2p). Thereafter, the lamp 2 is inserted into the opening 9 (Fig. 2q). In the present embodiment has
    Page -13- 95-7095 the lamp has an approximately funnel-shaped reflector, which rests with its front edge form-fitting manner at the opening 9.
    The concrete section, which extends outwardly from the opening 9 of the hollow body 1, forms a channel 25. The channel 25 extends to an outer surface 26 of the concrete wall. Both the surface of the channel 25 and the surface of the outer surface 26 form a visible surface of the concrete wall 5. Such a concrete wall is also called exposed concrete.
    The channel 25 widens in a funnel shape from the opening 9 of the hollow body 1 to the outer surface 26 towards. The channel 25 thus acts as a reflector with, of course, compared to a conventional mirror reflector reduced reflection properties of the concrete surface. The concrete surface of the channel causes a diffuse radiation. The surface of the channel is thus glare-free. As the luminaire is slightly offset from the outer surface of the concrete wall, it emits light only in a narrow solid angle bounded by the channel. An observer can thus look directly at the luminaire only under a very narrow solid angle. Outside this solid angle, it can not be blinded by the light.
    As the channel 25 extends a distance into the concrete wall, a viewer essentially sees only the concrete surface and a bright light source at the bottom of the channel, giving the impression that the concrete wall itself is glowing. This integrated into the concrete wall 5 arrangement with the light 2 can therefore be called a concrete light. The channel 25 may be formed in any shape and depth, as long as the thickness of the concrete wall allows. Between the surface of the channel 25 and the outer surface 26 of the concrete wall, there is no material transfer, so that there is a uniform continuous concrete surface. This is preferred for aesthetic and architectural reasons.
    A second embodiment of the invention will be explained below with reference to FIGS. 6 to 10. This embodiment in turn has a hollow body 1, a lamp 2, a formwork body with a hard core 3 and a soft shell 4, a cover 9 for the hollow body 1 and tabs 12 on the hollow body 1 ♦ · Μ · * · ··· * ·· «Μ * • * * * * · · Λ • fl * · I ·» * • ♦ · · * · »···» * * * * · «« · * * * * · · · ··· 7095
    Page -14- on. Unless otherwise stated below, the individual parts are the same as in the first embodiment and a corresponding description is therefore omitted.
    The shape of the hollow body 1 of the second embodiment differs from the shape of the hollow body of the first embodiment in that one of the two end side walls 7 is arranged inclined with respect to the bottom wall 5. in this inclined end face wall 7, the opening 9 for insertion of the operating device 10, the lamp 2 and the exit of the light emitted from the lamp 2, formed.
    The two-part formwork body with the hard core 3 and the soft shell 4 has the shape of an oblique truncated cone with a base surface 27 in the form of an ellipse and an opposite end face 28 in the form of a circle slightly larger than the opening 9 in the inclined end wall 7 is.
    The hard core 3 of the shuttering body has four through holes 13 for receiving a threaded screw 14, respectively. Furthermore, two U-profiles 18 are provided, which can be arranged in the cross. The U-profiles 18 have holes at their ends which can be brought into engagement with pins 17 formed on the inside of the inclined end wall 7 so that a cross consisting of the two U-profiles 18 locates the opening 9 in the hollow body 1 in a fixed manner can be. In the U-profiles 18 holes are formed, each associated with a nut 19, which is preferably fixedly connected to the respective U-profile. In these nuts 19, the threaded screws 14 can be screwed to fix the shuttering body 3, 4 on the hollow body 1.
    The second embodiment of this formwork system additionally has a base plate 29, which has approximately the shape of the base surface 27. The base plate 29 has small through-holes 15 which serve to receive short pins or nails 17 for fixing the base plate 29 to a component shutter 20. On the side facing away from the component shutter 20 side locking projections 30 are formed on the base plate 29, which with corresponding recesses in the base - • ft ft ••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••• ftftftft * ft * ft * ft * ft * ft ft AT-7095
    Side -15- surface 27 of the formwork body, in particular the hard core 3 of the formwork body interact. The shuttering body can be plugged onto the base plate 29, wherein the latching projections 30 cooperate with the corresponding recess of the formwork body such that the formwork body is firmly fixed on the base plate 29 and thus also on the component formwork 20.
    Instead of the latching projections 33 and corresponding latching recess, any other connection means for connecting the shuttering body to the base plate 29 may also be provided, such as e.g. a bayonet lock, screw connection, etc.
    The assembly of the formwork system and the production of a concrete wall with an integrated luminaire will be briefly explained below with reference to FIGS. 7a to 7j. The method steps essentially correspond to the method steps explained above with reference to the first exemplary embodiment, unless otherwise stated below.
    The soft shell 4 is placed on the outside of the inclined end wall 7 concentric with the opening 9 and the hard core is inserted into the shell 4 (Figure 7a). As a result, the opening 9 is closed.
    Through the through holes 13 a threaded screw 14 is inserted in each case (Figure 7b). On the inside of the inclined Stirnseitenwandung 7, the two arranged in the shape of a cross U-profiles 18 are used so that they are penetrated by their end-side holes of the pins 17. The threaded screws 14 are screwed into the nuts 19, so that the formwork body is firmly connected to the hollow body 1.
    The base plate 29 is fastened to the component formwork 20 by means of the metal pins 16 (FIG. 7d). At the locking projections 30 of the base plate 29 of the formwork body is placed with its base surface 27 and connected by means of the locking means consisting of the locking projections 30 and the corresponding locking openings in the hard core 3 of the formwork body with the formwork 20 (Figure 7e). * · ** ·· *** · »* · ** ·· *** ·» ΑΤ-7095

    The tabs 12 are adapted to the height of the reinforcing iron 21. At the connection piece 11 empty tubes 22 are attached (Figure 7f). Thereafter, the lid 8 is placed and the hollow body 1 is fixed with a wire 23 to the reinforcing rod 21, wherein at the same time the lid 8 is held on the hollow body 1.
    The component formwork is poured with concrete 24 (Figure 7h), wherein the formwork system according to the invention is enclosed by concrete. The concrete is cured in the component formwork 20.
    After curing, the component formwork is first removed from the hardened concrete wall. This results in the drawn in Figure 7i view, in which the formwork body 3, 4 inserted in the concrete wall. The base plate 29 was removed together with the component formwork 20 from the concrete wall. The threaded screws 14 are unscrewed, whereby the formwork body 3, 4 is released from the hollow body 1. Thereafter, the formwork body is removed from the concrete wall by first pulling out the hard core 3 and then releasing the soft shell 4 from the surface of the concrete wall (Figure 7j).
    The two U-profiles 18 are lifted from the pins 17 and led out through the opening 9 of the hollow body 1. Just as in the first embodiment, a control gear 10 and the lamp 2 are connected to the corresponding electrical lines and inserted into the hollow body 1.
    Due to the obliquely arranged formwork body 3, 4 results in a relation to the outer surface 26 of the concrete wall obliquely extending channel 25 which widens from the opening 9 of the hollow body 1 to the outer surface 26 out. Since the formwork body is a truncated cone, this channel 25 has a circular cross-sectional area. In the context of the invention, the channel 25 may be formed with other cross-sectional shapes and other profiles in cross section. For this purpose, different examples are listed below.

    Figure 11 shows a modification of the first embodiment, in which a light emitting diode array 31 is used as a lamp. On the back of Leuchtdiodenar-rays, a heat sink 32 is arranged. There are light emitting diode arrays available on the market that radiate most of their light within a range of +/- 60 ° around the op-5 tables axis of the light emitting diode array 31. At the edge area the luminosity is lower than in the center. As a result, most of the light can exit from the channel 25 unhindered. However, the surface of the channel is illuminated with relatively low light intensity, so that it is clearly visible to a viewer. In addition, such a light-emitting diode array 31 has a very low overall height. The heat sink 32 10 can also be adapted to the specific shape of the hollow body 1. In particular, it is expedient to provide one or more passages between the light-emitting diode array 31 and the opening 9, so that an air exchange of the air in the interior of the hollow body 1 with the environment is possible. Of course, such passages can also be provided in conventional luminaires which do not have light-emitting diodes.
    Separate vents may also be formed by communicating hoses or tube elements communicating with the hollow body with e.g. 20 circular or rectangular cross section are led to the formwork and thus limit a leading into the hollow body ventilation shaft in the finished concrete wall.
    FIG. 12 shows a third exemplary embodiment with an oblique channel and light-emitting diode array 31 and the heat sink 32.
    In the embodiments illustrated above, the light source is arranged in the hollow body 1. In the context of the invention, it is also possible to arrange the lighting means in the hollow body 1, in the channel 25 or even outside the channel 25 (Figure 30 13).
    In the embodiments described above, the component formwork 20 is formed planar. However, the component formwork may also be uneven, ········································································································ · Ftftftft AT-7095
    Side -18- which in particular in the region of the channel 25 may be useful to extend the channel 25 in the room. Figures 14 and 19 show schematically such a uneven component formwork.
    FIG. 15 schematically shows different ground plan shapes of the channels, which can be combined with different cross-sectional shapes of the channels and flat or uneven component formwork. The different cross-sectional shapes each show different cross-sectional profiles of the channel 25. The different component formworks result in different surfaces that may be formed in the region of the channel 25. Basically, each floor plan shape can be combined with any cross-sectional shape and any formwork. As a result, a variety of different channel shapes can be generated. A few examples are shown schematically in FIGS. 16 to 21, wherein the combination of the ground plan shape, cross-sectional shape and structural part formwork is shown in each of these figures and the surface of the concrete wall with the channel 25 is shown in a grid pattern on the right next to it. which results in this combination. Preferably, the transition between the outer surface 26 of the concrete wall and the inner surface of the channel 25 is continuous and preferably without an edge, i. that the first derivatives in the region of the transition are also continuous. Such an embodiment is shown for example in FIG. 16.
    In the context of the invention, it is also possible to form the opening 9 elongated, slot-shaped and / or angled. Figure 21 shows a corresponding embodiment.
    In the embodiments explained above, the holding elements in the form of the U-profiles 18 are placed directly on the inner surface of the wall of the hollow body 1, in which the opening 9 is introduced. However, it may be zweckmäßit to arrange these holding elements with a small distance from the inner surface of the respective wall. For this purpose, for example, small base under the pins 17 form, on which the holding elements 18 rest. In this way, the tapered or tapered formwork body can be a piece drawn into the opening 9, whereby the edge of the opening 9 is sealed and yet the formwork body does not cover the outer surface of this wall. This will ensure that this wall is completely covered with concrete and is no longer visible after curing of the concrete wall.
    Above ventilation shafts are described, which improve the cooling of the lamp by an exchange of air with the environment. In the context of the invention, it is also possible to bring the lamp or heat sink connected to the heat in thermal contact with embedded in the concrete heat conductors. As a result, the heat of the lamp is registered in the concrete, which has a high heat capacity. In particular, metal rods, e.g. made of aluminum or copper. It is also possible to use as a thermal conductor the iron reinforcement of the concrete. This has the advantage that the iron reinforcement usually extends over the entire or at least a majority of the concrete wall and so a large-scale distribution of the heat of the lamp is possible.
    Furthermore, a transparent ring, which is colored with a predetermined color may be arranged around the lamp, that the channel 25 is illuminated with this color. As a result, the channel 25 lights in the color of the ring. The ring may be formed of a transparent, temperature-stable plastic or glass. This is particularly useful in conjunction with a light-emitting diode array, since this optimally illuminates the channel.
    The formwork body according to the invention with a hard core and a soft shell can also be provided for forming a channel for receiving a button from a switch, sockets, fire detectors or motion detectors. These devices can be arranged frameless in the concrete wall, here the channel is rather short to keep, and a depth of e.g. 5 mm to 15 mm.
    Furthermore, channels for audio systems and ventilation in a concrete wall can be created with the formwork body according to the invention with a hard core and a soft shell. These channels are of a depth of e.g. 5 cm to 15 cm form. AT-7095 page -20-
