The invention relates to flooring systems designed especially for industrial premises containing equipment for data processing, such as data centers, computer rooms and facilities where there is a raised floor, towering over existing floors. Such raised or raised panel flooring usually use removable panels that are installed end-to-end on the raised part of the support for the formation of a free space where conduit, cables, compartments, wires and other items for the interconnection of computers.

There are many systems pelsparite, including those that use the adjustable stand in each corner of the panel as supports. Rack support such systems are located only at the corners of the panels, which typically have a square shape with a side of from 500 to 600 mm, Respectively, the rigidity and mechanical stability of the floor should be achieved through the use of very thin panels, usually of a thickness of from 30 to 40 mm, is sometimes used frame, which transmits the load of the racks. Because of the loss of useful height pelsparite these types of required total height from 150 to 200 the number of premises with additional height. For example, if one considers the possibility of using raised floor height of 200 mm at each level tridtsatiminutnogo buildings, the required additional height will be six meters, the equivalent of two floors. Installing a raised floor in existing buildings requires the creation of ramps and steps, as well as sound insulation and fire barriers. Finally, these structures sometimes make noise and act as resonators. In any case, installation of the existing floors as part of improvements to buildings or new construction is complicated and expensive.

Many other systems pelsparite used plates for the base, from which emanate the tabs that support the floor panel. For example, in U.S. patent N 5,052,157 ("patent '157"), which is incorporated fully herein by reference, describes a great "coating System, designed especially for industrial premises containing equipment for data processing". The system described in the patent '157, solves many problems associated with previous systems, including the problems described above. However, in patent '157 discusses and illustrates the formation of parts of the system "by talawaan or ABS."

Although such materials are ideal for the formation of components for which they are proposed in patent '157, in particular, from the point of view of complex surfaces of some of these components, the use of these materials in some specific applications associated with discomfort. First, the bearing capacity of such structures with a raised floor panel using such plastic material is partially a function of the quality and type of the used plastic materials, and it may be difficult to provide a high load capacity for these plastic structures at affordable prices and without unwanted weight. In addition, although the nature of the application and use of substances and additives that slow burning and suppressing the occurrence of smoke, can provide a valid safe use of such plastic materials as materials of construction, but nevertheless some fire safety rules may restrict or prohibit the use of plastic structures as raised panel cover.

Accordingly, the author of the present invention has developed a low profile floor panel, with straeten fully herein by reference. Application '447 describes a "plate for the base, made of thin sheet metal, typically galvanized steel, and have a butt on your existing floor, to which are attached the struts in the form of a rectilinear pattern as supports for floor panels, which form a raised floor or a raised floor and are usually covered with carpet. "Each backup has" [a] tab on the end of each arm of each poloski [which] fits tightly in the hole of the base plate and bent so as to be opposite to the soles of the base plate formed under there pressure". Thus, the struts can be collected in the base plate, which may have "[s] cords or cuts... to separation or to facilitate its cutting during installation".

The metal support structure described in the application '447, is non-flammable, with improved load capacity and easy to build coverage. However, the price of this system, the metal coating may be substantially higher than the price of a plastic material that can be used with the systems described in the patent '157. Obviously, the high price is a function of the generally more expensive metal (from the point of view of the I. Moreover, the need for separate production of base plates and props, and then assemble them, complicates (and subsequently increases the price) coating system. Of course, the collected coating system may also have a significant weight in the range from 10 to 12 kilograms per square meter of coating. This weight, in addition to the mass of metal base plates, makes it more difficult not only loading and transportation of metal base plates, but also their use for a floor covering system. Moreover, for multi-storey buildings, which are huge areas in which it can be installed coating system, it is very important for weight reduction system of the cover, and it is desirable to reduce the load on a structure.

Moreover, during the placement of the end user of base plates on the floor, it may be difficult to give appropriate form to the base plates, so you can install them in the corners or the space remaining after covering the rest of the floor. Although this problem has been partly solved by the formation of burrs or slack of base plates that allow some flexibility in the formation of base plates during installation in Pokrywa in the process, carefully handle plate base to give them the appropriate form.

Accordingly, there remains a need for low profile surface coverage using components that are compatible with the most stringent fire safety requirements, capable of providing high load capacity, cheap and avoid the drawbacks of the aforementioned systems.

THE ESSENCE OF THE INVENTION.

The problem to which the invention is directed, is the creation of lightweight, low-profile surface coating that provides a high load-carrying ability, adaptability Assembly and installation. This is achieved in that the coating system contains a set of stripes, each of the strips is formed of at least two columns, separated by sections of flat strips, each hour has a Central section forming a coupling element for attaching the floor panel, and there is a device for connecting strips and the floor panel supported by the racks.

In preferred versions of the system covering each of the racks may have a Central raised section supported by the first and second ruperiority leg, each of which is fortified area and a wedge; the strip can be formed of whether can vzaimodejstvie and to seal bracket; floor panel and rack form channels, with a device for the distribution of utility lines passing through these channels; the distribution device may have a housing located between the selected rack, which is formed with the possibility of fixing in place by contact with the racks; the casing may have essentially the same height as the rack, and in the upper part of the casing may be formed in a flange shape which is adapted for fastening the tops of at least two grounds; you can run the racks with the Central section, forming a first coupling element, as well as with the legs, reinforced rounded corners, to attach the Central part to the bands.

Another problem to be solved is the creation of a system of coating, forming channels that can reside and be switched line for various purposes. Coating system for the formation of channels intended for laying cables, contains modules located essentially on the floor, the modules contain interconnected strip having a support containing the Central part with the first coupling element, and a device for holding in position the Central part of the holds above the floor supports and has a second coupling element, designed for fixing the first coupling element.

Junction box this system coverage may include: the totality of the parties related to their ends for forming a closed casing; a flange made of at least one side and having openings; at least one slit made in the casing, where is the outlet; and a device for connecting the receptacle to the casing.

Another challenge is the creation of high-tech method of forming a support. According to this invention, the method for forming the support includes steps: providing a set of racks from a single first strip; providing a set of racks from a single second strips; join at least first and second strips; and the step of providing a set of intersecting stabilizing brackets from each band.

This method can include the step of forming two grooves in the shape of a cross at the top of each rack. The bonding may be accomplished by connection of intersecting stabilizing brackets of the first strip with the second strip.

In the present invention are used strip lisati strip. From the main strip with racks perpendicular to the thin strips of material, or the wings (which are also formed from the main strip), intended for coupling with the other wings of the main bands carrying the rack. Interconnected together a set of lanes, bearing of the rack, together forming some module having a rectilinear grating relief with racks connected through strips and wings. On the floor can be positioned and attached to multiple modules. Then on the rack modules are installed panels to form a raised floor, which would include furniture and equipment, and under it can be a data line and a power supply line, is routed through the channel network formed floors, racks and panels. Thus, the coating system can be made of metal or other incombustible materials and has a high bearing capacity.

As strips and wings, cross-cutting hours, do not cover the entire area between the posts, you need less material to build a system of support, which consequently greatly reduces the cost of the entire coating system. Moreover, since the support vzaimodeistvie difficulties related coverage uneven floors hard cover system. The system supports more lightweight and easier to transport, it is more maneuverable and easier going. In addition, thanks to its lightness, reduces the load on the structure, which is installed coating system. At the height of the rack 55 mm this coating system weighs approximately 4-5 kilograms per square meter of coating. At the height of the rack 85 mm coating system weighs approximately 6 kg per square meter of coating. This is a significant weight reduction compared to the coating of other materials.

Although the coating system of the present invention and is more lightweight, but it still retains a huge carrying capacity. Carrying capacity can be further increased by forming rounded corners on the edges of the legs supporting the Central top surface of the racks. Such rounded corners provide additional structural support for the upper surface, which runs parallel to the floor surface and supports the floor panel.

Moreover, like props, described in the patent '157 and in the application of the '447, the rack of the present invention may also containing a screw hole and a conical recess for receiving the screw, inserted through the corner of the floor panel, the edges of which are bent down for a better grip with grooves of the base. Conical recess closes the hole, thereby increasing the retaining force when screwing the screw.

Alternatively, one screw can be fixed floor panel having a cutout in the shape of a quarter circle in each corner so that after placement of floor panels adjacent to each other in a lattice pattern, together they formed a hole through which is supplied screw. Brackets baseboards or lip which partially surround the perimeter of the floor panel, are in the hole, forming shelves or ledges. On this shelf set ring, in which is placed the single screw. The end of the screw enters into the conical recess in the center of the support posts. The screw holds the protruding legs plinths (and thus outdoor panel) between the ring and the bar and rigidly fixes the floor panels to prevent buckling or other movement. The plinth or lip, in addition, can be placed in a crosswise grooves tightly enough to prevent movement of the floor panels. It is obvious that IP is Bork coating systems, thereby reducing the cost. During use of this system with a Central screw to attach the floor panels to the posts, the ring may be made of copper or other conductive materials for electrical interconnection system coverage.

The cover system is installed by covering the entire surface of the floor modules. The band that connects the individual rack has holes into which can be inserted nails or screws to attach the assembled module strips to the floor. Alternatively, the module can stick to the floor corresponding binding substance. The modules are aligned and firmly attached to the floor in the direction of the longitudinal axis. Other modules accordingly are located at some distance along the other side, so you can install the floor panels, which will be supported by these posts. These modules can communicate so that there is conductivity between adjacent modules to provide electrical grounding. After covering the main part of the floor modules, the user may want to adjust the final modules that must be installed in the remaining Ob, it turned out that there is no need to form a cutoff line or bend. You only need to use a pair of scissors or other cutting tool to fit the module to the desired surface.

After you install modules in the racks can be assembled junction box. The junction box may be one of those described in the U.S. patent of the same author with the serial number N 08/218,373, incorporated fully herein by reference, and may include a casing with four interconnected sides, which form a quadrangle with collections designed for sockets. This casing may be formed of sheet steel or other suitable material so that it can be fixed in place by attachment to the posts. Junction box acts as a coordinating link between (1) supply lines, communication lines, data lines or other service lines running through the channels formed under the raised floor and (2) the equipment installed on the raised floor, which can communicate with one or more service lines. Different receptacle in the junction box can productimage type, or junction box may have holes for the supply lines through the junction box directly to a specific piece of equipment.

Installation of junction boxes is performed without the use of fixing means such as screws, glue or rivets, as the cover of the junction box has a shape that allows tightly to install it between the posts supporting the panels above the floor of the structure. The casing may consist of a single unit or multiple parts, collected in various forms, preferably rectangular, each of which is rigidly fixed between the posts supporting the floor panel. No need to use any means of fixation or special fixing materials, since the frictional contact between the posts and openings in the sides or edges running along the top of the casing, to hold the casing in place. Using the cover of this structure, the junction box can be fixed in fact between any group of racks in the area covered by the raised floor. Below we will provide a coating system that provides the channels, which can accommodate data cables, cables podeshevel could make access to them.

The coating system of the present invention is formed from flat strips of galvanized steel coils. The set of rolls is mounted together so that the flat strip unwound from rolls in parallel relation to each other. Then the flat strips are stamped so that the edges of the flat strips formed of L-shaped notches to form wings, and holes are formed in the four quadrants in the form of a cross, formed in the upper part of the uprights. Then, having a quadrangular shape the wings bend under substantially right angle (90o) with respect to the longitudinal axis of the flat strip. As the strips are parallel and are at an appropriate distance from each other, the wings will be mutually molestias and then can easily sew, knit, or to communicate in any other way. Then from a continuous, interconnected strips are cut pieces of the same length to form a module, and rack any punching and formed from a module, and rack are in place holes in the forging process and between each set of wings.

Separate columns are formed from flat strips by welding, grinding and cutting, not covering the module, is controlled by the gap between the posts and stripes, and this gap has a variable value). Although hours may have a cross-shaped grooves and holes for coupling with the floor panels, but it is necessary that the main supporting form consisted only of a Central support portion that is supported above the floor by at least two legs.

Therefore, the aim of the present invention is the provision of a support with a set of racks that have improved the carrying capacity and which can be formed from a strip.

Another objective of the present invention is the provision of a support formed by mutual connection of the module together strips, formed from them racks, through the wings, which are also formed from these bands.

Another objective of the present invention is the provision of a system covering at least part of which consists of non-flammable material.

Another objective of the present invention is the provision of coating systems, where modules racks covered the floor panels forming the channels, which can be to the data line, the transmission line electricity is de modules cover the floor and have at least one junction box, motionless racks modules, and which can be installed in effect in any area of the floor to interact with the service lines located in the channels of the coating system.

Another objective of the present invention is the provision of a method of creating patterns of support, which forms the basis of the coating system.

Other objectives, features and advantages of the present invention will become apparent after reference to the rest of the text and drawings of this application.

DETAILED DESCRIPTION OF DRAWINGS

Fig. 1, 6 and 7 illustrate the execution of the rack support 10 of the present invention. Each rack 10 has two legs 12, connecting the Central part 20 with a connecting strip 30. The legs 12 have rounded corners 14, which provide additional carrying capacity. Rounded corners 14 can be formed from the connecting strip 30 by bending (partial drawing) edges connecting strip 30, leaving the edge forming angle 16. Additionally legs 12, which are first and second extension 13 and 15, from the Central part 20 to the connecting strip 30, are connected to connecting the th flexible material, of which may be formed of the leg 12.

Legs 12 support the Central portion 20, which may extend for forming a cross-shaped grooves 22 for receiving the auxiliary parts of the floor panel 60 such as a protruding lip 66, which runs along the perimeter of the floor panel 60 and which can be coupled with the top of the rack 10, as shown in Fig. 3. The groove 22, in addition, parts of the Central part 20 on four tip 24, each of which has a hole 26 in the conical recess 28 for receiving securing means. The conical recess 28 causes the closing holes 26 as a fixing means such as screws (not shown), is twisted, thereby improving its ability to hold the screw (and thus of the floor panel 60, which passes through and is fixed with the screw) in place.

The rack 10 are arranged in parallel rows and columns, forming a sequence of parallel channels perpendicular to each other. Although the rack 10 can be made of galvanized steel, of a thickness of about 0.75 mm, for 10 hours, with a height of 55 mm, but when necessary can be used and other material, other thickness. When using hundred the population accordingly to specific areas of the racks 10 to provide sufficient bearing capacity for a specific height used rack 10. Alternatively, more or fewer racks 10 may be connected by connecting strips 30 and the wings 40, and the gap between racks 10 can vary as needed or in accordance with the design. As can be easily seen from Fig. 2, adjustment of the length of the wings 40 or connecting strip 30 changes the density of the uprights 10, located in the module 50. For example, reducing the length of the wings 40 and connecting strips 30 increases the density (and therefore the overall carrying capacity) rack 10 in the module 50.

However, the structure shows the performance of the uprights 10 is such that the bearing capacity is the optimal value for this particular thickness. This structure contains rounded corners 14 and the wedge 18 and shown in Fig. 1, 6 and 7. In addition, the legs 12 have a first extension 13, which emanates from the Central portion 20 at an angle of two degrees and a half (2,5o) in the direction of the connecting strip 30. The corners 14 (as seen in Fig. 7), in addition, have the second extension 15 that extends at an angle of approximately one whole and one quarter degrees (1,25o). The first and second extensions 13 and 15 feet 12 increases the carrying capacity of the rack 10 without creating the need to use more thin the th composition or alternatively, through holes 32 in which are mounted screws or nails, the connecting strip 30 resists any possibility of slipping of the legs 12 to the outside at the time of placing the goods at the Central part 20.

Transverse stability of the connecting strip 30 and the rack 10 is provided with a number of wings 40, which perpendicularly extend from the connecting strip 30 and bonded to the wings 40 of the parallel bars 32 (which, moreover, is attached to the floor (F). The wings 40 are formed from the connecting strip 30 by forming the L-shaped cut 42 on the edge of the connecting strip 30. The wings 40 are then bent to the formation of strong ties 44. Where two connecting strips 30 are parallel and have accordingly mutually aligned rack 10, the curved wings 40 are mutually molestias and then can be connected through loops 46. Details of the relationship of the wings 40 by means of the lugs 46 shown in Fig. 4 and 5. The first wing 41 neglective second wing 43. Then formed eyelet 46 to the joint connection of these two, the first and second wing 41 and 43. The second wing 43 has a groove 47 in which is formed a protrusion 45. The groove 47 is in the form of a swallow's gvineria. Thus, the lug 46 is rigidly attaches the first wing 41 to the second wing 43.

After connection, in accordance with what is shown in Fig. 2 and 8, the rack 10, the connecting strip 30 and the wings 40 take the form of a rectilinear grid with sixteen legs 10, collected in one section of four rows and four columns. However, it is clear that for effective fastening of racks 10 connecting strip 30 and the wings 40 may not be perpendicular in relation to each other. Can be used in any angular orientation of the connecting strips 30 and wings 40 for the relationship of the racks 10 in the module 50. In any case, the inherent flexibility of this relationship racks 10, connected by strips of material in the modules 50, allows you to easily install modules 50 even on uneven areas of the floor F. Thus decreases the noise from the movement (e.g., return) system coverage and facilitate the collection system coverage.

The module 50 has first and second edge strips 34, 36, each of which has a flange 52 which forms the wings 40. Thus, the edge 52 and the ends 54 define the boundaries of the module 50. Second, the same module can be installed so that its ends will be positioned at the ends 54 of the module 50 so that the rows 58 stoey from the edges 52 of the module 50 so that to form parallel rows of racks 56 10 that allows you to properly support the floor panel through the racks 10 of these modules. Alternatively, the first and second edge strips 34, 36 can have wings 40 for communication with other modules. Such or similar inter-module communication can be sufficient for the electrical interconnection system of the coating so that the whole system could serve as an electrical ground. Floor panel 60, if they are made of metal, can also provide electrical connection between the modules 50.

Fig. 2 and 8 illustrate the junction box 70, located between several racks 10 of the module 50. The junction box 70 has a casing which is composed of four sides 72, converging at angles of ninety degrees (90oin the corners 74, forming a quadrangular perimeter bounding an open area 76. Each of the sides 72 has an upper edge 78, which has a cut-out 80. The junction box 70 may be formed by stamping or other means of a suitable metal, such as sheet steel so that two of the sides 72 could be welded spot welded or fastened in any aircraft, from which is formed the junction box 70.

The junction box 70 is installed in effect at any point on the floor between any of the groups of racks 10 so that each of the cutouts 80 connected with the upper part of the corresponding rack 10. To fix the junction box 70 can be used in different system of fastening, such as a system of grooves in the top of the rack 10, for attachment to the upper edge 78, or jointing compound. In one of the sides 72 of the junction box 70 has a receptacle 82, which can be used to supply electrical power lines, data lines, communication lines or other service lines running through the channels formed by the floor panels 60, the floor F and a-pillar 10. Such lines can pass not only through the channels, but also between the legs 12 of the uprights 10, for connection to the junction box 70, which thus serves as a distribution center to which you can connect installed above the floor plates 60 power supply equipment or to provide other services. Access to a plug socket 82 and another open area 76 can be carried out through the aperture, which moreut system with a Central screw 170 for attaching the improved floor panel 172 to the rack 180, which has a conical recess 182 leading to the Central screw hole 184, which can install the Central screw 186. Hour 180 has a groove 22 in the form of a cross, which form recesses for accepting a mating plinth 177, partially around the perimeter of each floor panel 172. Each corner 174 of each floor panel 172 has a cutout in the shape of a quarter circle 176. Each cutout 176 reveals two protruding bracket 179 plinth 177, which together form a shelf on which you will install the ring 188, which may be formed from conductive, but malleable material, such as copper, to best adapt to small changes in the thickness of the brackets 179 each floor panel 172.

As shown in Fig. 9 A, when the floor panel 172 is set at 180 hours, they cut together form a circular opening 178 with a shelf formed directly below the top floor panels 172, with brackets 179, protruding from a hole 178 formed by cutouts 176. In this hole 178 is set to ring 188 and is located on the brackets 179 projecting from the baseboards 177 flooring panels 172. The screw 186 is screwed into the ring 188 to contorta 184 for better fixation of the Central screw 186. The Central screw 186 thus captures some of the floor panels 172 between the ring 188 and the upper part of the rack 180, preventing the movement of fixed floor panel 172. Skirting 177 each floor panel 172 may, in addition, coupled with the grooves 22, locking floor panel 172.

In Fig. 10 shows a schematic depiction of a top view on the process of creating modules 50. At the initial stage 100 shown flat strip 102, made of galvanized steel and received by the unwinding of the coils 101 in four parallel lines. On stage stamping 110, flat strip 102 are stamped using the media and devices perforation installed on a hydraulic press or other appropriate device for forming L-shaped sections 42, holes 26 and grooves 22. The edges 52, if necessary, can also be L-shaped sections 42.

Following along to compound 120, we will see that pressed strip 104 has a rectangular wedge shaped L-shaped sections 42, bent at substantially right angles to the stamped strips 104 to form wings 40. The wings 40 naglestad, due to the fact that the stamped strips 104 are arranged in parallel on Rel is dealing with the wings 40 are fixed by brackets 46 during shtabelirovanija 130. Familiar with this technical field, it is known that there are a number of ways of securing the wings 40, such as for example, the formation of hooks on each end of the wings 40, which will then snap together. Alternatively, you can use a seam formed from nylon or other suitable material, for mutual connection of the wings 40 whose ends can have a ribbon for a more rigid (but adjustable) connection joints. However, the bracket 46 shown in Fig. 3, 4 and 5, have some advantages, including a reliable connection between the wings 40 that they provide.

Directly after a process of joint shtabelirovanija wings 40, continuous stamped and fastened with staples strips 106 are cut on the ends 54 in accordance with the desired length, depending on the number of racks 10, which must be ustanovit end module 50 or depending on the required size of the module 50. Then in step stamping racks 140 are formed of a rack 10, which are stamped the row in areas where they were formed grooves 22 and openings 26 in the step of imparting a 110. After completion of the step of imparting a rack 140, the result is a fully formed madisonavenue, for the relationship of the stands 10, strips of a suitable material, which results in material savings. In addition, where the rack 10 are formed from the same flat strip from which are formed the band for the relationship (for example, connecting strip 30 and the wings 40), the process of forming the coating systems of the present invention greatly simplified with a corresponding decrease in costs.

There are alternative ways of creating the basis for the covering system of the present invention. For example, the rack 10 can first be formed from flat strips 102. The wings 40 may then be formed by creating the necessary L-shaped sections 42, folded and placed over a rectangular wedges for the formation of the wings 40. The combination of the connecting strips 30, each of which has a number of racks 10 and wings 40 may then mutually joined and cut to form module 50. Alternatively, for the relationship in the module 50 together connecting strips 30 may use a different material different from material of the wings 40.
