BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     This invention relates to a method for constructing a secure cabinet, and for subsequently paneling an equipped and connected rack structure with paneling elements and at least one door, as well as to a kit for executing the method. 
     2. Description of Related Art 
     It quite often occurs that, because of changing operating conditions or uses, already assembled and ready-to-operate rack structures need to be protected to a greater or lesser extent. Some examples are protection against dust, splashing water, noise and fire, which require the subsequent paneling of the rack structure. 
     SUMMARY OF THE INVENTION 
     It is one object of this invention to provide a method for constructing a secure cabinet, and in particular a subsequent paneling of a ready-to-operate rack structure, which can be performed easily and without interfering with the rack structure. 
     This object is attained in accordance with this invention with a rack structure that is raised by at least the thickness of a bottom element. The rack structure is placed and positioned on the bottom element positioned below. A front grooved element with connecting elements for a door element is placed on the bottom element in the area of the front of the rack element and is there connected. The front grooved element is connected with side elements placed on the bottom element. A rear grooved element or a rear wall element is placed on the bottom element in the area of the back of the rack structure and is connected with the two side elements. A top element is placed on the grooved elements, the side elements and possibly the rear wall element and is connected with the grooved elements and/or with the side elements. 
     With a lifting element, the rack structure can be raised to the height required for sliding the bottom element underneath it without releasing the connector cables. Once the bottom element has been slid underneath it, the rack element is put down and positioned in such a way that it projects on all sides from the rack element sufficiently far, so that the elements provided for paneling can be placed on the bottom element and connected with it, if desired. 
     If no rack element is provided, the secure cabinet can also be constructed without resorting to the first two steps in order to arrange built-in units in the cabinet later. 
     A front and a rear grooved element are used if the front and the rear of the paneled rack structure are accessible. If access is required only from the front, the back is paneled with a rear wall element and/or has an air conditioner. The connection of the elements with each other is performed at predetermined places, which are aligned with each other, of the horizontally and/or vertically abutting front faces of the elements, wherein the number of the connection points between two elements can be two or more in order to achieve sufficient support. 
     It is also possible to line up several grooved elements on the front and rear wall elements in order to construct a lined-up cabinet arrangement, wherein the intervening side walls are omitted, and several bottom elements or one common bottom element can be employed. 
     In accordance with a preferred embodiment of this invention, the front and the rear grooved elements are assembled from vertical and horizontal frame legs in the form of a frame. In this case it is possible to reduce the required elements so that the front and rear grooved elements are identically embodied. 
     In another embodiment used for the same purpose, the bottom element and the top element are identically embodied. 
     A simple assembly of the paneling, which can be quickly performed, is achieved because known turning bar closures are used for connecting the elements, whose closure elements are matched to each other, and are installed in the elements at abutting faces of connecting points aligned with each other. Such hook closures are commercially available, wherein the two closure elements can be installed in the abutting front faces of the elements. The hook can be rotatably seated in one closure element and can be inserted into the other sleeve-like closure element. After being inserted, the hook is turned on top of a clamping bolt and is appropriately clamped during an additional eccentric displacement, so that the elements connected with each other are pulled toward each other under tension. Thus, the elements need only have one access opening to the rotary bearing of the hook, so that the hook can be turned in the associated closure part. 
     So that uniform connecting elements can be used at all connecting points, a further embodiment provides that the vertical frame legs of the grooved elements are designed L-shaped in cross section and have connecting faces for the vertical side elements. 
     In accordance with a preferred embodiment, the structure of the elements is designed so that the elements are embodied to be double-walled and are filled with insulating material. 
     Thus it is possible to advantageously provide an insulating material having sound protection and/or fire protection properties, which is enclosed in sheet metal walls. 
     In order to seal the joints between the elements in a fireproof manner, in one embodiment the joints between the elements are sealed by highly temperature-resistant sealing elements, which expand in the event of fire. 
     The attachment of the doors can easily be achieved because the front and the rear grooved elements are closed off by door elements, wherein the vertical frame legs of the grooved elements and the door elements have hinge and closure elements at points matching each other. 
     A kit for executing the method in accordance with the invention includes: 
     a) panel-shaped structural elements, side elements and top elements; 
     b) frame-like front grooved elements; and 
     c) frame-like rear grooved elements or panel-shaped rear wall elements; 
     all of which are connected by complementary connecting elements at the abutting horizontal and/or vertical front faces at connecting points, which are aligned with each other, and can thus be connected. 
     To reduce the number of different required elements, the bottom elements and the top elements, as well as the front and rear grooved elements, are each identically embodied. 
     For compartmentizing the secure cabinet, horizontal frame legs are provided at least partially with fireproof and gas-tight cable bulkhead elements. 
     The interior can be easily enlarged because several grooved elements, or rear wall elements, are sealingly connected with each other, while omitting the side elements.

     DESCRIPTION OF PREFERRED EMBODIMENTS 
     FIG. 1 shows elements for the structure of a secure cabinet, and for paneling in a closed or a closeable on all sides fashion, of a ready-to-operate rack structure. The kit comprises bottom elements  10  and top elements  70 , which are preferably embodied in a panel shape and are identical. The front is closed by means of front grooved elements  20 , which are assembled from vertical frame legs  21  and  22  and horizontal frame legs  23  and  24 . The vertical frame legs  23  and  24  are L-shaped in cross section, so that narrow front faces are provided on both sides for a connection with adjoining elements. This has one advantage that it is possible to install uniform closure elements in these front faces at all connecting points. A simple alignment of several secure cabinets is possible when omitting intermediate walls. 
     If the back is also closed by a door element  50 , a rear grooved element  40  is used, which has vertical frame legs  41  and  42  and horizontal frame legs  43  and  44  and can receive a door element  50  or a rear wall element  60 , for example an air conditioner. The rear wall element  60  can also be directly connected with the side elements  30 . 1  and  30 . 2  without a rear grooved element  40 . The same as the vertical front faces of the door elements  50 , the vertical front faces of the vertical frame legs  21  and  22 , or  41  and  42 , of the front or rear grooved elements  20  and  40  can have matched hinge and closure elements, as indicated by reference numerals  25 ,  45  and  51 . Because these elements are known for door fastening, they will not be discussed in greater detail within the scope of this invention, and sufficient structural embodiments are available for this purpose. 
     A turning bar closure is preferably used for connecting the elements with each other, as shown in FIG.  2 . The sectional view shows a connecting point between the vertical frame leg  21  and the horizontal frame leg  23  of the front grooved element  20 . Here, the closure part  80  with a rotatably seated hook  81  is installed in the vertical front face of the frame leg  21 , while the matching closure part  90  with the clamping bolt  91  is installed in the vertical front face of the frame leg  23 . As FIG. 3 shows, the hook  81  protruding from the frame leg  21  can be inserted into the sleeve-like closure part  90  and, by rotating it can be brought into engagement with the clamping bolt  91 . If, in the final phase of rotation the hook  81  is drawn into the closure part  80 , which can be effected by means of an eccentric element, the frame legs  21  and  23  are pulled against each other and clamped. 
     FIG. 2 also makes the double-walled construction of the elements visible. As an example, the frame legs  21  and  23  are enclosed by sheet metal walls  26  and  27 , the same as all elements, and are filled with insulating material  28  and  29 . The selection of the insulating material is determined by the sound protection, heat protection, fire protection, and other demanded parameters. The joint between the elements connected with each other is thus sealed by a sealing element  100 , which must be highly temperature-resistant when used as fire protection. 
     It is clear that the elements can be connected with each other, above each other along their vertical and/or horizontal front faces, wherein two or more connecting points are selected per element. The connecting elements are each formed by the two closure elements  80  and  90  and are aligned with each other. 
     The method in accordance with this invention is explained in greater detail in view of FIG. 4 wherein, for the sake of simplicity, only the frame structure of the rack structure is represented. Equipping with sub-assemblies can be arbitrarily performed, and the connector cables are preferably inserted through the side walls of the rack structure and connected. Tested, fireproof, water-tight and gas-tight cable bulkhead systems are used. 
     At the start of the method, the rack structure  200  is raised by a lifting device until a floor element  10  can be slid underneath it. The rack structure  200  is then placed on the floor element  10  beneath it and in the process is positioned so that the bottom element  10  protrudes for the same amount on all sides past the exterior of the rack structure  200 . 
     Then the front grooved element  20 , assembled from the frame legs  21 ,  22 ,  23  and  24 , is placed on the projecting portion of the bottom element  10  in the area of the front of the rack structure  200  and is connected with the bottom element  10 . Preferably two turning bar closures as shown in FIG. 3 are installed near the exterior of the lower horizontal frame leg  24  and the facing side of the bottom element  10  wherein, for example, the closure element  90  is inserted in the bottom element  10 , and the closure elements  80  are installed in the frame leg  24 . The bar shafts  82  are preferably embodied as tool receivers, which are accessible via access openings  83  in the frame leg  24 . 
     Once the front grooved element  20  is connected with the bottom element  10 , the panel-shaped side elements  30 . 1  and  30 . 2  are placed on the bottom element  10  and connected with the front faces of the free legs of the L-shaped vertical frame legs  21  and  22  of the front grooved element  20  and/or the bottom unit  10 . It is thus possible to employ respectively two or more turning bar closures per joint. As shown in FIG. 2, the joints are sealed by sealing elements  100 , which have desired properties. 
     The elements are embodied so that, together with the sealing elements  100 , they provide a desired protection, such as heat protection, sound protection, fire protection, protection against splashing water, or the like for the rack structure  200 . 
     The back of the rack element  200  can be covered with a rear grooved element  40 , which is assembled from the frame legs  41 ,  42 ,  43  and  44 , wherein the connections between the frame legs can also have turning bar closures which are installed in the area of the joints and are sealed by means of a seal element  100 . 
     As FIG. 4 shows, the free vertical front faces of the side elements  30 . 1  and  30 . 2  have closure elements  80 , with bars  81  that can be inserted into closure elements  90  which, with their clamping bolts  91 , are installed in the vertical frame legs  41  and  42  of the rear grooved element  40 . A door element  50  can also be hinged on the rear grooved element  40 . However, a rear wall element  60  can also be inserted into the rear grooved element  40  and connected with the rear grooved element  40 . A rear wall element  60  of an appropriate size can also be directly connected with the lateral elements  30 . 1  and  30 . 2 . It is possible to provide all horizontal and vertical joints with two or more turning bar closures. 
     At the end, a top element  70  is placed on the grooved elements  20  and  40  and the side elements  30 . 1  and  30 . 2  and they are connected with each other and with it in the area of its joint using turning bar closures. In this case the access openings  83  to the rotating shafts  82  of the bars  81  can be accessible from the outside or the inside of the completed paneling. 
     In one embodiment, the bottom element  10  and the top element  70  are identical. The same also applies to the front grooved element  20  and the rear grooved element  40 , and the side elements  30 . 1  and  30 . 2  are also identically embodied. Thus the number of different elements required is reduced. Uniform connecting elements, for example known turning bar closures, are employed at all connecting points. Other closures are also conceivable. 
     A cutout, through which the connector cables are conducted to the rack structure  200 , can be provided in the rear grooved element  40  or the rear wall element  60  in the area of the rear of the rack structure  200 . The connector cables in the cutout can be sealed by a cable guide, which can be subsequently inserted.
