Description

The invention relates to a cover of a substrate made of edge-joined and materially interconnected profiled cladding sheets of a metallic material, which are each provided with a auflegbaren on the ground base and on opposite sides in the longitudinal direction extending first and second edge edgings.

Such covers are known, for example, on the DE 20 2014 102 114 U1 is referenced. They serve, for example, to permanently cover and seal the underground ceiling of underground garages or bridge components.

So far, exposed to the weather conditions ceilings of underground garages or bridge components, the problem that they do not reach the intended life, since moisture penetrates and it comes to massive damage to the underground construction. It has therefore already been variously proposed to permanently seal the ground with joined shares of a metallic material and to seal, but the assembly designed so far consuming.

This is where the invention comes in and proposes a cover that can be laid and created particularly quickly and easily and, moreover, can also be easily checked for leaks after the installation has taken place.

To achieve the object, the embodiment of a cover according to the features of the protection claim 1 is proposed according to the invention.

Advantageous embodiments and details of the invention are the subject of the dependent claims.

The invention proposes to provide the trim panels of the cover according to the invention with a first edge upstand which projects upwardly with respect to the base and provide an opposing second edge edge raised from the base to a highest edge and subsequently to the highest edge an attachment leg is bent down. Adjacent cladding panels are then materially connected to each other in the region of their respective opposite first and second edge edging, such that the first edge edging of a cladding sheet rests on the mounting leg of the adjacent cladding panel and is welded longitudinally thereto and the mounting legs to their free end in some areas fixed to the ground holding profile are fixed.

The attachment and installation of the cover according to the invention is therefore carried out successively in such a way that first a first cladding sheet is connected in the region of its attachment leg with at least one retaining profile, which in turn is secured in the ground. This attachment in the subsurface can be done, for example, by bores introduced into the subsurface, which is usually made of concrete, and screws received therein, optionally with the aid of dowels in a manner known per se. For the fixation of the fastening leg, only a retaining profile can be provided or corresponding numbers of retaining profiles are provided for fixing at preferably regular intervals. This depends on the respective requirements and can be selected accordingly by the person skilled in the art.

After the first cladding sheet is connected in such a way by means of the holding profiles in the region of the mounting leg to the ground, another cladding sheet is added to the edge of the already attached cladding sheet, such that the upwardly protruding first Kantenaufkantung on the mounting leg of the already fixed cladding sheet comes to rest and in This position is materially connected by means of a continuous in the longitudinal direction of the cladding sheets weld with the mounting leg.

Subsequently, on the opposite longitudinal side of the second cladding sheet in turn, the associated mounting legs are anchored by means of retaining profiles in the ground and the process begins with a third edge-side clad trim sheet of new, etc. In this way, in a simple to bewerkstelligender handcrafted procedure within a short time a large area of Substrate are provided with a cover according to the invention, which is due to the achieved by welding cohesive connection of the individual cladding sheets together reliably and permanently tight, so that the life of such a covered subsoil, such as an underground car park or a bridge component, is reliable and secured over a long period ,

According to a proposal of the invention, the first edge of the edge up to its free end on a parallel applied to an adjacent mounting leg and weldable with this joining portion. The joining of the Cladding sheets and welding of the first and second edge edgings is thereby enormously simplified. Preferably, the fastening leg as well as the joint section extend substantially perpendicular to the ground, but may also have deviating angular orientations thereof.

According to a further proposal of the invention, the joined panel panels completely cover the retaining profiles with their welded first and second edge edgings, so that they are no longer visible after the cover according to the invention has been produced below the panel panels joined together at the edge. The screwing of the retaining profiles in the ground are thus no longer visible after completion of the preparation of the cover according to the invention.

According to a further proposal of the invention, the holding profiles on their side facing away from the ground on a receiving groove into which a mounting leg is inserted. In this way, a particularly simple connection of the mounting leg can be achieved with the anchored in the ground holding profile, optionally even a pre-connection, so that already upon delivery of profiled in accordance with the invention cladding the retaining profiles in a sufficient number of the mounting legs of the individual not yet welded cladding panels are pre-assembled. As a result, the assembly effort is further reduced.

According to a proposal of the invention, the receiving groove can be aligned substantially perpendicular to the ground and limited by webs, with transverse bores are provided in the webs to carry out fastening means for the inserted mounting leg. The preferably in this case perpendicular to the ground extending mounting leg needs to be plugged therefore only in the receiving groove with its free end and fixed by means of transverse fastening means in the transverse bores. Depending on the configuration of the transverse bores, a circular booking cross section for forming fixed bearings or a slot-shaped bore cross section for forming a movable bearing can be realized in this case in order to allow the cladding sheets, for example, a thermal expansion.

According to a further proposal of the invention, the receiving grooves in the retaining profiles are aligned substantially parallel to the ground and the mounting legs are angled in the region of their free end corresponding to substantially parallel to the ground. Such a retaining profile, for example, in the way of pre-assembly can be threaded end face into the still single profiled trim panel according to the invention by the angled free end is threaded into the receiving groove of the retaining profiles. These are then freely displaceable along the longitudinal extent of the cladding sheets, so that are formed in a simple manner floating bearing and can be set for the design of fixed bearings, for example, either with screws or spot welding on the mounting leg.

According to a further proposal of the invention, the joined lining panels of the cover according to the invention in the region of their welded first and second edge edging each define a sealing space above the substrate and at least one closable nozzle is provided, via which a test gas can be introduced into the sealing space. In this way, the created welded joint between the first and second edge edging of respectively joined cladding sheets of the cover according to the invention, for example in the dye penetration or by means of sniffing probes in a conventional manner after creation of the cover to be tested for leaks.

According to a further proposal of the invention, the base of the cladding sheets is connected to the substrate with the interposition of strips of a mounting adhesive, for example a polyurethane foam or suitable silicone. In this way, not only an additional sealing of the sealing space for the leak test of the weld made, but the mounting adhesive also causes an advantageous for easy installation pre-fixing a cladding on the ground before this means of the support sections and the weld with the substrate or is connected to already laid cladding sheets.

Further embodiments and details of the invention will be explained in more detail with reference to embodiments in the drawing. Show it:

From the 1 to 3 is a partial view of a cover of a substrate 5 , For example, an underground car park made of concrete visible, with two profiled cladding panels only partially shown 3 . 3a are joined together at the edge.

The profiled cladding panels joined together at the edges 3 . 3a each have a matching and from the 5 in fully visible profiled cross-section, starting from one on the ground 5 auflegbaren and parallel to this extending base 30 merges into edge upstands at both longitudinal edges, of which the in 5 on the left side positioned edge edging as the first edge Aufkantung with reference numerals 31 is provided while in the illustration according to 5 on the right side of the edge called the second edge Aufkantung edge Aufkantung with reference numerals 32 is provided.

The first edge upstand 31 extends from the substantially horizontally extending base 30 at an angle from here about 55 ° upwards, ie from the ground 5 away and goes over a slightly less inclined section in a perpendicular to the base 30 and to the underground 5 extending joining section 311 about, which so far protrudes vertically upwards and the free end of the first edge portion 31 forms.

On the opposite side extends the second edge Aufkantung 32 also initially from the horizontally extending base upwards and here at an angle of about 75 ° to a highest edge 320 which extends substantially horizontally further outward. From there leads a mounting leg 321 essentially vertically downwards, ie this runs approximately perpendicular to the base 30 and the underground 5 and runs in a direction perpendicular to the 1st edge Aufkantung 31 angled free end 322 the second edge Aufkantung 32 out. The free end 322 extends in this respect again approximately parallel to the base 30 and to the later underground 5 and is positioned so that when you hang up the base 30 on the ground 5 a greater distance to the ground 5 as the base 30 having. However, this distance is only a few millimeters.

Such trained first cladding sheet, that in the drawings according to 1 to 3 with reference number 3 marked and only in the area of the right-side second edge Aufkantung 32 is shown, with the background 5 connected by a more detailed from the 4 apparent holding profile 2 is used, which according to the course of the free end 322 one also essentially parallel to the ground 5 aligned open receiving groove 20 for the free end 322 of the attachment leg 321 having.

This is the holding profile 2 with a bottom leg 21 for example, made of a steel sheet, which under formation of the receiving groove 20 with his end 210 bent over 180 °. In addition, at some distance to the end 210 an L-shaped angle 24 with a gift 24a . 24b on the bottom leg 21 for example by spot welding 26 attached. The arrangement thus produced is frontally on the free end 322 of the attachment leg 321 pushed and in the longitudinal direction of the cladding sheet 3 freely displaceable, with the free end 322 in the receiving groove 20 is recorded positively.

Then not shown holes in the ground 5 inserted and fastening screws 25 through holes 250 in the thigh 24a as well as the bottom leg 21 introduced the holding profile 2 including the free end recorded therein 322 the second edge Aufkantung 32 firmly with the underground 5 connect. Due to the free mobility of the cladding sheet 3 along its longitudinal axis relative to the retaining profile 2 In this way, a floating bearing is formed, which is a thermal expansion of the thus attached trim profile 3 allowed. If a fixed bearing should be provided, a fixation between the holding profile 2 and the free end 322 be effected for example by a spot weld or by another introduced fastening screw.

The previously explained slightly increased positioning of the free end 322 the second edge Aufkantung 32 in comparison to the base 30 allows positioning of the bottom leg 21 below the free end 322 , like from the 1 and 2 visible and also allows a certain height compensation by varying the depth of engagement of the fastening screws used 25 ,

In addition, the base becomes 30 of the thus by means of the holding profile 2 fixed cladding sheet 3 by interposition of previously applied strips 6 a suitable one Assembly adhesive, for example PU foam, with the substrate 5 prefixed.

It is understood that, depending on the longitudinal direction of the cladding sheets 3 . 3a extending total length thereof only one of the drawings apparent holding profile 2 or a plurality of such retaining profiles 2 be used in regular or irregular sections for attachment in the manner already described.

Having thus the first profiled cladding sheet 3 with the substrate to be sealed 5 has been connected, is a subsequent equally trained cladding sheet, which in the illustrations according to 1 to 3 with reference number 3a is marked, at the edge of the already attached or installed cladding sheet 3 added, first by the first edge Aufkantung 31 same in the area of the joining section 311 at the parallel thereto mounting leg 321 the second edge Aufkantung 32 the previously laid fairing sheet 3 is created. In this orientation, the second panel is 3a again by means of strip-like application of assembly adhesive 6 with the underground 5 pre-connected and then a longitudinally joined the two facing cladding sheets 3 . 3a continuous weld 34 , which is created for example in the MIG or TIG process, along the upper edge of the joint section 311 and the corresponding area of the attachment leg 321 created, then the two adjoining cladding sheets 3 . 3a cohesively and tightly interconnected.

After the second cladding sheet 3a in this way with the first cladding sheet 3 over the weld 34 may have been connected on the opposite side in the area of the second edge Aufkantung 32 by means of holding profiles 2 in the manner already described a fixation on the ground 5 take place and the process with further cladding sheets be repeated until the entire surface of the substrate 5 in the desired manner by the forming cover 1 from edge-side joined and cohesively interconnected cladding sheets 3 . 3a is created.

Finally, the tightness of the welds used 34 between joined cladding sheets 3 . 3a For example, be tested by a test gas according to methods known per se, since the joined cladding sheets 3 . 3a in the area of their welded first and second edge upstands 31 . 32 a sealing room 33 above the ground 5 limit, in addition, by means of the underside stripes 6 the assembly adhesive is sealed gas-tight. About at least one in this sealing space 33 leading and for example the highest edge 320 penetrating neck 323 can a test gas under appropriate pressure in the sealing chamber 33 are introduced and then the weld 34 For example, in the color penetration or by means of a sniffer probe for leaks to be tested.

Furthermore, according to the illustrations according to 1 - 3 removable, that after the formation of the cover 1 the used holding profiles 2 together with their screw connections in the underground 5 completely from the welded edge edging 31 . 32 the panel sheets 3 . 3a be covered and are no longer visible in this respect.

From the 6 is another embodiment of such a cover 1 a background in which the same parts have been given the same reference numerals and will not be explained again separately to avoid repetition, unless this is necessary for understanding the invention.

Substantial difference to that already on the basis of 1 bi 5 illustrated embodiment is the embodiment of the retaining profile 2 , which has a receiving groove here 20 which is essentially perpendicular to the ground 5 as well as to the bottom leg 21 runs and to the top, ie on the ground 5 opposite side is open. This recording groove 20 is made of two mutually parallel and, for example, with welds 216 on the bottom leg 21 right-angled welded U-legs 22 . 23 limited.

According to the vertical orientation of the receiving groove 20 in the illustrated embodiment, the mounting leg 321 in the area of his free end 322 rectilinear vertically oriented downwards and so far perpendicular to the base 30 and to the underground 5 aligned and can directly into the corresponding vertically extending receiving groove 20 be introduced.

As in particular from the enlarged view according to 7 can be seen, has the holding profile 2 in the area of both the receiving groove 20 limiting U-thighs 22 . 23 cross holes 220 . 230 on, by a fastener, such as a screw (not shown) can be performed to a fixation of the free end 322 on the holding profile 2 to effect. If, as shown, the cross holes 220 . 230 are formed as slots, so that a floating bearing is formed, so that a thermal expansion of the cladding sheets 3 . 3a is possible or the transverse holes 220 . 230 are designed as cylindrical drill holes, which gives a fixed bearing.

The panel sheets 3 . 3a can be made in particular from suitable stainless steels, for example by means of roll formers, which covers 1 are obtained, which reliably and permanently meet the building physics requirements for waterproofing of buildings, such as underground car park ceilings and bridge components.
