[0002] In balcony construction, it is well known that the floor of a balcony attached to a house wall should have a slope descending from the wall outwards to allow rainwater or other liquids to drain away from the building. If necessary, drainage can also be directed towards the house wall, provided a suitable drainage channel is installed. For this purpose, the flooring is usually delivered pre-sloped, or installation involves constantly adjusting and checking the slope, which is time-consuming, prone to errors, and laborious, especially when constructing larger balconies, terraces, or roof terraces.

[0033] Fig. 1 Figure 1 shows a floor system 1 for a balcony B that is only indicated, the surround and railing of which are not drawn, wherein the floor system 1 is arranged on a building wall W of a building G that is not shown in detail.

[0034] Four cantilever arms, K1-K4, project horizontally outwards from the building wall W. These cantilever arms support the load of the balcony B and any people and objects on it in a manner known per se. The cantilever arms K1-K4, particularly their upper bearing surfaces, project horizontally outwards from the building wall W in a cantilever direction K. "Horizontal" in this context means that the cantilever arms K1-K4, and especially their upper bearing surfaces, are essentially perpendicular to the vertical. Therefore, the cantilever arms K1-K4 have no slope in a vertical direction H, which is perpendicular to the cantilever direction K and parallel to the vertical. The alignment of the cantilever arms K1-K4 may deviate slightly from the horizontal, but this deviation is typically only a few millimeters per linear meter.In the present embodiment, the cantilever arms K1-K4 are designed as single-ended wooden beams or cantilevers; however, the parts of the cantilever arms K1-K4 that project freely beyond the wall W can also be supported by posts. The cantilever arms can also be made of other materials, for example, as steel beams. Instead of the four cantilever arms K1-K4 described here, more or fewer cantilever arms can be provided.

[0035] Floor system 1 features a floor covering 2, which is as described in Fig. 1 clearly consists of a multitude of floor panels, wherein, for the sake of better presentation and explanation of the invention, Fig. 2Only floor panels 2a and 2b are shown as examples. These floor panels are aligned with their long sides in the cantilever direction K and laid side by side in a horizontal longitudinal direction L running perpendicular to the cantilever direction K. The floor panels 2a and 2b can also be connected to each other by means of a quick-release connection, particularly a releasable one, such as a tongue and groove, click, or snap connection.

[0036] To attach the flooring panels 2a, 2b to the cantilevers K1-K4, longitudinal support profiles 3, 4 extending in the direction L are attached to the cantilevers K1-K4. A first support profile 3 is provided on the side of the floor system 1 closer to the building wall W. This first support profile 3 has several, in this case three, successive support profile elements 3a-c extending in the longitudinal direction L of the support profile 3. A second support profile 4, located at the outer edge of the balcony B and in the area of ​​the free ends of the cantilevers K1-K4, has, like the first support profile 3, three support profile elements 4a-c, which again extend in the longitudinal direction L of the second support profile 4.

[0037] As in Fig. 3 and 4Clearly visible, longitudinal mounting rails 9a-d for the first support profile 3 and an exemplary mounting rail 10 for the second support profile 4 are provided on the cantilever arms K1-K4 in the direction L, in order to attach the support profile elements 3a-c and 4a-c respectively to the cantilever arms K1-K4. The method of attachment is explained below, primarily using cantilever arm K2 as an example. Fig. 3 for the second support profile 4 and Fig. 4 The instructions for the first support profile 3 on the wall side are described. The same applies to the other mounting rails 9a-d, 11 and support profiles 3-4.

[0038] On the upward-facing side of the cantilever K2, an elongated, longitudinally L-oriented anti-slip surface 17, for example made of plastic or rubber, is arranged as a base for the mounting rail 9b, 10. The anti-slip surface 17, uniformly designated with the same reference numeral, can optionally also be designed as a damping element to dampen the impact energy transferred to the cantilever K2 by footsteps on the floor covering 2, and possibly also the impact sound. The anti-slip surface 17 can optionally be omitted.

[0039] The elongated mounting rail 9a or 10 is then placed centrally on the anti-slip device 17 with respect to its longitudinal extent in the longitudinal direction L. For fastening to the cantilever arm K2, the mounting rails 9b or 10 have an opening in the form of a bore (not further specified). A fastening screw 12, uniformly designated with the same reference numeral in the drawings, is inserted through this opening and then screwed into the cantilever arm K2. If necessary, several fastening screws 12 can be used instead of just one, and other fastening methods are also conceivable. For example, threaded rods projecting upwards into the cantilever arm K2 can be inserted, and the mounting rails are then placed onto them with the opening and subsequently screwed in place with a nut.

[0040] The mounting rails 9b and 10 then extend longitudinally L, i.e., perpendicular to the cantilever direction K, beyond the cantilever arm K2. Subsequently, the support profile elements 3a, 3b and 4a, 4b, located to the right and left of the mounting rails 9b and 10 respectively, are slid onto their ends of the mounting rails 9b and 10 until they almost touch the side walls of the cantilever arm K2. Preferably, a small gap, e.g., 5 mm, is maintained at this point to allow for thermal expansion of the support profile elements 3a, 3b and 4a, 4b, for example, at high temperatures. A cover element 6b or 7b is then placed from above onto the mounting rail 9b or 10 via the gap remaining between the support profile elements 3a, 3b or 4a, 4b above the cantilever arm K2. These elements also rest on the cantilever arm K2 and close the gap.

[0041] Preferably, the projection of the fastening rails 9b or 10 in the longitudinal direction L over the cantilever K2 is at least three times, preferably two to three times, the width of the support profile elements 3a, 3b or 4a, 4b.

[0042] As in Fig. 3 and 4 recognizable and in Figs. 14 and 15 As shown again in detail in the cross-section, the floor covering 2 is designed to have a slope from wall W towards the outside of the balcony B in the cantilever direction K, i.e., towards the free ends of the cantilever arms K1-K4. This is intended to allow liquid, especially rainwater, that comes into contact with the floor covering 2 to flow away from the building G and prevent the liquid from collecting on the floor covering 2 or even flowing towards wall W. If a drainage device is provided on the wall side, for example a drainage channel, the slope can also be directed towards wall W.

[0043] For this purpose, the support profile elements 3a, 3b and 4a, 4b exhibit the following: Fig. 6The detailed cross-section and the mounting rails 9b and 10 are shown in the Fig. 7 The cross-section shown is shown. The different mounting options for the support profile elements 3a, 3b and 4a, 4b on the mounting rails 9b and 10, respectively, for adjusting the slope, are then shown. Figs. 2 to 4 , 8, 10, 12 and 14 to 16 The same applies to the other support profile elements 3a-c, 4a-c, 5a-c and the mounting rails 9a-d, 10 and 11. The invention is described below primarily with reference to the support profile elements 3a and 4a; the explanations apply analogously to the other support profile elements.

[0044] The support profile element 3a has, as shown in Fig. 6 It is evident that an upper floor support 30 for the floor covering 2 is provided. In the longitudinal direction L, two longitudinal grooves 31a, 31b are provided in the upper surface of the upper floor support 30, into which Figs. 14 to 19The elongated damping elements 18a, 18b shown, hereinafter referred to by the same reference numeral, preferably elongated plastic or rubber ribs, can be used and clamped in place. Optionally, no longitudinal grooves 31a, 31b, only one, or more than two may be provided.

[0045] The undersides of the longitudinal grooves 31a, 31b serve as supports 32a, 32b for the support profile element 3a on the mounting rail 9b. Side walls 32a, 32b, extending downwards in the vertical direction H, adjoin the base support 30 and preferably run at a 90° angle to the base support 30. The side walls 33a, 33b are then connected by upper and lower partition walls 34, 35, respectively, which run perpendicular to the side walls 33a, 33b and parallel to the base support 30, thereby dividing the space into an upper hollow chamber 36, a middle hollow chamber 37, and a lower hollow chamber 38. The lower hollow chamber 38 is then closed off at the bottom by a base 39 connecting the ends of the side walls 33a, 33b.

[0046] The hollow chambers 36 to 38 are adapted with their inner contour to the outer contour of the mounting rail 9b or 10. The mounting rail 9b has lateral, longitudinally L-oriented, wedge-shaped locking grooves 13a, 13b into which corresponding wedge-shaped locking lugs 36a, 36b, 37a, 37b or 38a, 38b in the side walls of the hollow chambers 36 to 38 engage. As in Figs. 8, 10 and 12As can be seen, the mounting rails 9b and 10 completely fill the lower and middle hollow chambers 38, respectively, with the underside of the partitions 34 and 35 resting on the upper side of the mounting rails 9b and 10, respectively, and the load of the floor covering 2 being transferred to the cantilever K2 via these surfaces. In the upper hollow chamber 36, however, the upper side of the mounting rail 11 rests on the supports 32a and 32b formed by the underside of the longitudinal grooves 31a and 31b, which is sufficient for load transfer. Alternatively, instead of the supports 32a and 32b projecting into the hollow chamber 36, the floor support 30 can also be made of solid material, so that its underside rests fully on the mounting rail 10. The present design, however, is sufficient for stability and saves material.

[0047] As in Fig. 3 , 4 , 8 and 14To create the slope, the support profile elements 3a, 3b with their lower hollow chamber 38 are attached to the mounting rail 9a from the wall side. The support profile elements 4a, 4b furthest from the wall, on the other hand, are attached with their Fig. 10 and 15 The central hollow chamber 37 shown is attached to the mounting rail 10, as shown in Fig. 3 and 15 shown. This results in the particular comparison of Figs. 14 and 15 clearly recognizable height difference of the floor support 30 of the first support profile 3 and the floor support 40 of the second support profile 4 with the resulting slope of the floor covering 2 from the wall side to the front face of the cantilever K2, i.e. in the cantilever direction K.

[0048] As in Fig. 3 , 4 and 15As can be seen, the end faces of the support profile elements 3a, 3b and 4a, 4b almost abut the side walls of the cantilever K2 again; here too, a certain distance is advantageously provided to allow for thermal expansion. The resulting gap is then closed by means of a cover element 6b or 7b, which is further divided into Fig. 9 or 11 are shown in cross-section.

[0049] In order to attach the cover element 6b to the mounting rail 9b, the base 39 of the support profile element 3a was omitted or is subsequently removed at the installation site, so that a lower hollow chamber 66 of the cover element 6a is open downwards in a U-shape and laterally bounded by side walls 63a, 63b. Since the cover element 6b, like the other cover elements, is preferably made of extruded aluminum profiles, the free lower ends of the side walls 63a, 63b exhibit a certain degree of elasticity, so that the cover element 6b, with its U-shaped legs of the side walls 63a, 63b, can be attached to the mounting rail 9b from above in the area of ​​the lower hollow chamber 66.The locking lugs 66a, 66b of the downwardly open lower hollow chamber 66 are pushed over the side walls of the mounting rail 9b until they engage in the corresponding locking grooves 13a, 13b of the mounting rail 9b, thus enabling tool-free assembly of the cover element 6b and attachment to the mounting rail 9b.

[0050] Accordingly, the cover element 7b of the outer, wall-remote support profile 4 has only a lower hollow chamber 76, which is separated from an upper hollow chamber 74 by the partition 75. The middle hollow chamber 68, as in cover element 6b, has been completely omitted. This can either be provided by prefabricated cover elements or on-site during assembly by supplying only "complete" cover elements 6b and then cutting off their lower hollow chamber 66 along with the lower partition 67. Alternatively, only the profiles for the support profiles can be supplied in one piece, which are then cut to the length required for cover elements 6a and 7a. Subsequently, the base 39 for cover element 6b or the lower hollow chamber 38 along with the partition 35 for cover element 7b is cut off.

[0051] The cover element 7b is then also placed on the mounting rail 10 from above and locked into place in the locking grooves 13a, 13b by means of the locking lugs 76a, 76b.

[0052] Since, during assembly, the floor panels 2a, 2b of the floor covering 2 are placed on the floor supports 30 of the support profile elements 3a, 3b or the floor supports 60, 70 of the first and second support profiles 3 and 4, respectively, there is no risk that the cover elements 6a, 7a, which are snapped onto the mounting rail 9a or 10, will accidentally become detached from the mounting rail 9a or 10. Rather, the floor covering 2 then securely fixes the cover elements 6a or 7a to the mounting rail 9a or 10.

[0053] As in Fig. 2 , 3 and 5 The first support profile 3 is shown with its in Fig. 3The left-hand edge support profile element 3a is attached to the cantilever K1 by means of a cover element 6a. An alternative mounting rail 9b is provided, which projects beyond the cantilever K1 only on one side in the longitudinal direction L, namely towards the adjacent cantilever K2. The mounting rail 9a is inserted into the corresponding hollow chamber 38 at the end face of the support profile element 3a, as described above.

[0054] To provide a clean and ingress-resistant end face for the support profile 3, the cover element 6a is closed at its outer end, the end facing away from the support profile element 3a, with an end cover 14 in the form of a cover plate. The end cover 14 is fastened to the mounting rail 9a with screws 15, the screws 15 being inserted into the Fig. 7The screws 15 can be screwed into the clearly visible pre-drilled holes 16 of the mounting rail 9a. The same applies to the other end of the support profile 3 and the cover element 6d. Alternatively, dowels can be inserted into the mounting rail 9a, into which the screws 15 can then be screwed. The end cover elements 6a and 6d can also be manufactured and delivered with a permanently attached cover plate, e.g., welded on.

[0055] Figs. 20 and 21 show an alternative flooring system 201, which differs from the one in Figs. 1-3 The design shown differs essentially in that cantilever arms K1'-K4' are almost twice as long and project twice as far from the building wall W as those shown. Figs. 1 and 2The cantilever arms K1-K4 are shown. With this large cantilever length, it becomes necessary not only to provide two support profiles 3, 4, but also to arrange a third support profile 5 at the edge of the cantilever arms K1' to K4'. Floor covering panels 202a, 202b then have correspondingly adjusted lengths and are attached to the support profiles 3-5 in the manner described above.

[0056] In order to provide the required slope of the floor covering 202 for the third support profile 5 facing away from the wall, even with the additional length, the respective support profile elements 5a-c of the third support profile 5 are each attached with their upper hollow chamber 36 to mounting rails 11 for the third support profile 5, as shown in Fig. 12 and 16shown. This results in a corresponding slope compared to the middle, second support profile 4, as between the first support profile 3 and the second support profile 4. The fastening rail 11 is again attached to the cantilever arms K1'-K4' as described above, in particular by screws.

[0057] Accordingly, cover elements 8a-d are then provided, which, as in Fig. 13As exemplified by the cover element 8b, it consists solely of a base support 80 with longitudinal grooves 81a, 81b on the upper side for the elongated damping elements 18a, 18b, the lower supports 82a, 82b for the mounting rail 11 of the support profile elements 5a, 5b of the third support profile 5, and the adjoining short side walls 83a, 83b with locking lugs 84a, 84b attached to the inside, thus providing a single, downwardly open hollow chamber 84. The assembly, namely attaching the cover element 8b to the mounting rail 11, then proceeds as described above for the other two cover elements 6b and 7b.

[0058] Figs. 22 and 23 together with Figs. 12, 13 and 17-19 show another alternative floor system 301, which is largely the same as in Figs. 20 and 21 The floor system 201 shown is similar in that it has a floor covering 302 and support profiles 3-5.

[0059] Unlike the one in Figs. 20 and 21 However, the floor system shown in 201 is such that the load-bearing profiles 3-5 are not attached to cantilever arms K1' to K4' projecting from the building wall W and firmly connected to the building G, but rather by means of Figs. 17 to 18 The fastening screws 306 shown are attached to crossbeams 304a-d of a pre-assembled support frame 303. The crossbeams 304a-d correspond to the cantilever arms K1'-K4' of the floor system 301. Figs. 20 and 21 and are connected to each other to form the supporting frame 303 by means of two longitudinal beams 305a, 305b extending in the longitudinal direction L. The crossbeams 304a-d and longitudinal beams 305a, 305b are preferably made of hollow steel sections, but other materials can also be used.

[0060] The support frame 303, together with the support profiles 3-5 attached to it in the same manner as described above, forms a frame-shaped subfloor construction 307, which can be transported in its entirety to the installation site and attached to the building wall W in a manner known per se. If necessary, the subfloor construction 307 can also be used for terraces or other flooring, thus reducing installation time. Alternatively, the floor covering 302 can be attached to the frame-shaped subfloor construction 307, allowing the entire flooring system 301 to be installed quickly and easily on site.

[0061] Instead of using 12 screws suitable for wood Fig. 3 , 4 and 14-16 The support profile elements 3-5 are screwed onto the support frame 303, in particular the crossbeams 304a-d, using fastening screws designed as threaded screws 306, as shown in Figs. 17-19As shown, corresponding internal threads are machined into the crossbeams 304a-d. Since the underbody structure 307 is preferably largely pre-assembled during manufacturing, the internal threads for the fastening screws 306 can be easily machined into the crossbeams 304a-d of the support frame 303 during pre-assembly. Therefore, a time-consuming process of threading the crossbeams 304-d during on-site assembly is unnecessary.

[0062] If the cover elements 6a-d, 7a-d or 8a-d are manufactured on site from support profile material during assembly, the length of the cover elements 6a-d, 7a-d, 8a-d can easily be adjusted on site in the longitudinal direction to the width of the cantilever arms K1-K4, K1'-K4' or the crossbeams 304a-d.

[0063] Instead of the support profile elements 3-5 described above, with hollow chambers 36-38 arranged one above the other in the vertical direction H, only two hollow chambers or four or more hollow chambers can also be provided, for example, if a terrace or a balcony with additional support on the side facing away from the wall is to be built with a greater width, which then has longer and / or more cantilevers or transverse and / or longitudinal beams. If necessary, the distances between the support profiles 3-5 can also be reduced if a particularly stable floor covering 2 is required.

[0064] Figs. 24 to 27 show another alternative floor system 401, which is largely the same as in Figs. 1 to 5 The floor system 1 shown corresponds to a floor covering 402 and cantilever arms K1-K4.

[0065] Unlike the one in Figs. 1 to 5The difference in the floor system 1 shown is that, instead of just one single-piece mounting rail 10 placed on the cantilever K2, a separate mounting rail 410a, 410b is provided for each of the support profile elements 4a, 4b. The mounting rails 410a, 410b are attached to the cantilever K2 by means of a mounting plate 411a, 411b running perpendicular to the longitudinal direction. This will be explained in more detail below, primarily with reference to the figure in Fig. 26 Support profile element 4a and the left mounting rail 410a, which are in Fig. 27 shown again in its unassembled state, described below.

[0066] The mounting plate 411a, like the end cover 14, is made of Fig. 5The mounting plate 411a is screwed to the end of the mounting rail 410a by means of two concealed screws 15. For this purpose, the mounting plate 411a has two openings, in particular holes, which align with the pre-drilled holes 16 of the mounting rail 410a. If necessary, dowels can also be inserted into the pre-drilled holes 16. Alternatively, the mounting plate can also be welded to the end face of the mounting rail 410a. Other fastening methods are also known to those skilled in the art for connecting the mounting plate 411a to the mounting rail 410a in such a way that the load imposed by the floor covering 402 can be transferred.

[0067] The mounting plate 411a extends laterally on both sides in cantilever direction K beyond the mounting rail 410a and also the attached support profile element 4a and has a through-hole in this overhang, in particular a bore for Fig. 27The fastening pins 412a and 412b shown are attached. The longitudinally extending fastening pins 412a and 412b are fastened in the cantilever arm K2, for example, by gluing or otherwise securing them. Optionally, the fastening pins 412a and 412b can be designed as wood screws on their side facing away from the fastening rail 410a, which can be screwed into the cantilever arm K2 or a pre-drilled hole in it.

[0068] At the free end protruding through the lateral openings of the mounting plate 411a, the mounting pins 412a, 412b have external threads onto which a mounting nut 413a, 413b can be screwed to fasten the mounting plate 411a or 411b to the cantilever arm K2. As shown in Figs. 26 and 27As can be clearly seen, the length of the support profile element 4a is chosen such that, under normal conditions, a gap, preferably up to 5 mm, remains in the longitudinal direction between the end face of the support profile element 4a and the mounting plate 411a. This allows for compensation of any changes in the length of the support profile element 4a.

[0069] If necessary, the fastening pins 412a, 412b can also be inserted through openings, in particular bores, extending completely through the cantilever arm K2 in the longitudinal direction L. In this case, the fastening pins 412a, 412b then have an external thread at both ends for the fastening nuts. This has the advantage that the fastening rails 410a, b arranged on the fastening plates 411a, b are aligned with each other in the longitudinal direction on both sides of the cantilever arm K2. To ensure this also for the non-through fastening pins 412a, 412b, the upper edge of the fastening plate 410 is designed so high that its upper edge is flush with the upper surface of the cantilever arm K2 when the fastening rail 410a is inserted into the uppermost hollow chamber 36 of the support profile element 4a, wherein the bottom support 30 of the support profile element 4a is also flush with the upper surface of the cantilever arm K2 in this position.

[0070] As in the above described versions, a slope of the floor covering 402 in the cantilever direction K is again created, in which the support profile elements 3a, b with their lower hollow chambers 38 are placed on the fastening rails (not shown) attached to fastening plates 414a, b, while the support profile elements 4a, b with their middle hollow chambers 37 are placed on the fastening rails 410a, b.

[0071] The cover elements 406a-d can then be reattached longitudinally L between the support profile elements 3a, 3b on the cantilever K2, for example by attaching a section of a mounting rail described above, which is at most as long in the longitudinal direction L as the cantilever K2 is wide, to the cantilever K2 in the manner described above. The cover element 406a can then be attached to this. Alternatively, the cover element 406a can also be screwed directly onto the cantilever K2. For the wall-remote support profile elements 4a-c, which are flush with the upper surface of the cantilevers K1-K4, no cover rails are required; the floor covering 402 rests directly on the cantilevers K1-K4 in this area. For this purpose, as described in Fig. 25 and 26As shown, the elongated damping elements 18a, b are extended over the cantilever arms K1-K4. It is sufficient that the damping elements 18a, b are held in the locking grooves 13a, b of the support profile elements 4a-c; an additional support on the cantilever arms K1-K4 is not necessary.

[0072] This alternative design allows the floor covering 402 to be positioned relatively close to the cantilever arms K1-K4 in the vertical direction, thereby reducing the overall height of the floor system 401. Furthermore, it is understood that the Figs. 24-27 The described design can also be used in principle with the frame-shaped subfloor construction 307. Reference sign
