Description

Fire cover for registration of installations.

The present invention object of request National utility model, consists of a new firewall cover  approved for the registration of service facilities that They are found in the interior boxes or skates of the buildings, to operate momentarily on some drive, valve, wiring strip, etc., or for simple inspection

Its usefulness is that being a product approved as a fire resistant door, complying with all the current regulations in this regard, presents an ideal design for the purpose that is intended, because it is a cover with a shape fully flat, with perfect alignment of the opening blade with the perimeter fence, where the hinges and the drive of closure remain hidden once the lid remains closed, then completely flush with the wall of engagement. In addition, the particular hinged and closed systems provided, makes the lid open in service easily by company key, and close simply by tapping, and that the blade can be replaced occasionally without needing disassemble the assembly

Given the ultra-flat shape of this lid record, which is perfectly camouflaged in the plane of the wall where it is placed, finds special application in the field of construction of unique buildings, where aesthetics play a important role, such as cultural buildings, housing, offices, etc.

But regardless of the above, the cover that presents also has some practical advantages no less important, such as its versatility, easy installation, easy opening and closing system, and even easy handling and palatization, speeding up the distribution and sale process.

State of the art

The industrial sector of fire doors has always been characterized by an important activity in Investigation and development; new materials, new boards, new designs, etc., as evidenced by the high number of patents that only exist in Spain on the subject. Without However, one thing is the fire-resistant doors for passage of people, and other covers or gates for the registration of facilities, in relation to this specific product, about which the present invention focuses on, no one has been found  patent taking effect in Spain.

Nor is the existence of any door known  patented firewall that, being used for the transit of people, have the same characteristics as the gate of registration of the present invention; that is, no one is known patent with effects in our country that reproduces the singular invention gate structure.

Doing a search in the OEPMPAT database of the Spanish Patent and Trademark Office, have been found some patents relating to fire doors for the passage of people that could be applicable as registration covers if were suitably sized, as if we were saying made in miniature; it is the case, for example, of the patent European with application number EP97119768, national patents P8800756 and PO418990, or utility models U200200982 or U200200519, all of which are related to constituted doors by a metal fence attached to miter and a metal sheet formed normally by two superimposed plates, one of them configured as a tray in which the insulating material is housed, and the other placed flat as a cover, joining both permanently by any conventional procedure, but none of those patents contemplate the novel coupling between the leaf and the fence of the lid of the present invention, concealed hinge systems and closing, nor the peculiar design of these.

In this lack of inventive activity in referring to registration covers for facilities has a lot to see the fact that until relatively recently it was not  strictly the installation of covers that were Homologues as far as fire resistance is concerned. It was not until the entry into force of the NBE-CPI-96 (Basic Standard for building, fire protection) and the new edition of the Regulation for low voltage installations (RBT 2002), which establish the obligation that the records have a Minimum fire resistance rating of 30 to 60 minutes (RF30 and RF60) in its section "link installations individual ", when this issue takes an important turn, because the manufacturers at that time have no choice but to react quickly and supply a byproduct derived from the minimization of the doors of people, distorting totally the "function-product" relationship that It must be associated with any article.

The dimensions of the plates are reduced considerably, since the records in many cases do not exceed the size of the passage of a hand, fundamental hardware is eliminated for the correct protective function that a cover must have against fires and there is no room for hinges, locks approved, etc., and, in short, it stays totally helpless during current regulations on door testing UNE 23802-79 firewall and EN-1634-2000, Spanish standards and European respectively, where possible extrapolations about measures as well as any variation possible between the prototype tested and the manufactured product.

It also goes without saying that these solutions of  urgency taken by manufacturers are quite unsightly and not very functional.

Therefore, it is necessary to offer the market a cover for registration of facilities really approved, in accordance with current regulations on resistance to fire, but also with a structural design from which they result practical advantages in terms of assembly and use, and that favor the standardization of the product, as is the case with doors of passage, in order to serve more quickly and with less cost.

And this is precisely what comes to solve the present invention: a cover for the registration of facilities that being approved as a firewall product, it is designed exclusively for that function, for which a Totally flat structure, with perfect alignment of the leaf with the fence and with concealment of the hinged systems and closing, which is easily opened by master key and close by tapping, without having to permanently leave a key in the lock, and in closed position the lid is completely flush with the wall of fit, improving the aesthetics of the places where it should be placed, which is not a matter of little importance, because the covers for registration of facilities have gone from being almost exclusively used in industrial buildings or low traffic, to be planned in areas where the appearance and decoration is very important.

The invention

Specifically, the inventive object that vindicated is a fire resistant lid or gate for the record of the facilities found in the tables or interior skates of buildings, the type of which are basically consisting of a quadrangular metal sheet or rectangular, formed by a prismatic box and a sheet metal lid superimposed, both galvanized steel, folded, assembled and unified by pressure, with filling of insulating materials such as rock wool and plasterboard, and by a steel canton fence galvanized, perimeter to the metal sheet, formed by four pieces, two stringers and two headboards, miter cut and properly fitted, including the intumescent board for prevent the passage of the flame in case of fire, four claws of anchoring to work and four assembly squares.

What essentially characterizes this Novel registration cover is as follows:

On the one hand, the shape of the metal sheet, with drawing of the closing drive, without protruding from the general plane, leaving the sheet completely smooth, and where the sheet that forms the sheet box presents along its contour a protruding flange at right angles on which the cover plate by means of a double bend at right angles, the length of said sheet crimping tab being the necessary for the lid to protrude from the box enough to hide both the leaf hinge system, located in one of its sides, integral to the box, as the system of closing of the same, embedded in the opposite side.

And, on the other hand, the shape of the fence, which in cross section presents two steps at right angles, one exterior that constitutes the metal sheet cover frame, which fits the fence by the crimping tab lid-box, aligning the lid with the wall, and other interior that remains hidden, where the leaf box sits, determining a labyrinthine step in stairs between metallic sheet and siege. The step outside the fence of the two headboards presents two holes at the end of its inner face, intended for pivot axis of the hinged system while in the middle of the step inside the fence of one of the stringers, the opposite of of the hinges, the housing hole of the closing slip.

The lid closure system is located fully embedded in the body of the metal sheet, being consisting of two cylinders inserted perpendicularly, one, of shorter length, embedded transversely in the body of the sheet from its mouth in the outer lid, the bulb being intended to house the master key, and the other, of greater length, embedded longitudinally from the side edge, being intended for the circulation of a slip latch, formed by latch, solidarity rod and spring, presenting the rod to the cylindrical bulb shaft height a conical bore  for the introduction of a master key with the same shape external, whose drive releases spring pressure, unlatched the lock latch and thus allowing the opening of the lid.

The slip latch used for closing by knocking on the door, it remains hidden behind the tab protrusion of the sheet metal cover, which keeps the door locked in at all times, without protruding from the general plane of the sheet.

The hinge system consists of two hinges located on one side of the sheet case metallic, one from the top and one from the bottom, being hidden from view from the outside of the lid in elevation position. Each of these hinges has the peculiarity that its axis of rotation constitutes a fine rod cylindrical supported on a spring and housed inside a Square section sheath. The sheath is screwed to the side of the box, with a longitudinal hole on the side opposite to that of overlap by which a pin for fixing the rod is inserted, which allows a pivoting movement under the path of the key through said side hole of the sheath.

Said pivoting movement of the stems of the hinged system, is what makes the metal sheet easy to mount on the fence, and then also be easily disassembled and exchanged, as needed.

It is, therefore, before a registration cover fire resistant basically formed by a set of leaf and metal fence, which allows access to the frames of installations of the walls of buildings or those that They walk the inner skates, good water, gas, electricity, etc., but with a functional improvement important, because due to the novel structure of the sheet and the fence that make up the lid, along with the peculiar systems of hinged and closed, the set is applicable to any type of work, without having to incorporate a key opening, since the lid opens with a company key and the closing is by tapping, remaining when it is closed, completely flush with the plane of the wall, being able even fulfill a decorative function if you choose a paneling or uniform color painted.

Indeed, the first important quality of the fire resistant registration cover object of invention is that it treats a product approved for this purpose, with classification "RF", fully protected by current regulations, to which we must add that it is a new product, while it is created to perform its function expressly, not being undersized or oversized based on other pre-existing ones with distinctive functions, and being much more flexible than Until now, open to any extension or legally possible modification proposed by installers or service companies

But what really makes this cover unique homologated record, is the achieved flush of the sheet with the fence and this one with the wall when the lid is in closed position, thanks to the whole structure fence-leaf and to the new hinged system and drive, which is hidden from the outside, forming the lid a single plane in continuation with the plane of the wall where you it places, that is to say, the cover is flush in the access points to the paintings or skids of the facilities, where they are Periodic inspections performed.

This is obviously an important advantage. for any building where its placement is planned, and especially in those where the decoration of spaces is prime interiors, as is the case with unique buildings, of offices or the ones destined for housing, because it can be reached to get registration covers for interior facilities really camouflaged on the walls where they are placed.

Note that the registration cover recommended has the possibility of being manufactured in pre-lacquered sheet in standard shades, or apply epoxy enamels to the oven in colors RAL, or even the possibility of subsequent paneling with materials M-O following the aesthetic line of the rest of a certain interior decoration project.

In addition, with a view to the companies suppliers, having flush all the elements of the sheet and the fence of the lid in question, the units are easily palletizing, being able to create both whole packages and individual packaging, for another type of market more detailed. With the new hinge and drive system, the right or left hand option, which reduces the 50% stock, creating great savings and comfort for suppliers and the work itself in their orders.

For the best understanding of the novel cover for records designed is attached to this report descriptive a series of drawings of the different details constructive of it.

Figure 1 shows the elevation of the fence (1) with the corresponding cross and longitudinal sections. Be see in hole A-A the hole (3) where enter one of the stems (10) of the hinge system to allow the rotation of the blade, which is hidden once the same.

Figure 2 shows the fence in perspective, where you can see the assembly of the two headboards (4), the place that occupy in them the holes (3) for the stems (10), and both  stringers (5), miter cut, in one of which find the hole for the closure (6).

Figure 3 represents the elevation of the sheet with their corresponding cross and longitudinal sections, where the two constituent parts of the sheet are appreciated: the box (7) and sheet metal cover (8), galvanized steel both folded and unified by pressure, and the insulating products (9) of filling. In the left part of the elevation the ends of both appear stems (10) with which the blade is attached to the fence, allowing its turn.

Figure 4 shows the detail of the section A-A of the previous figure in the area of closing drive (11), in this case of slip, which keeps the door locked at all times. In this drawing you clearly appreciate the protruding tab that forms the box when overlap with the sheet metal cover and by which the sheet is perfectly adjusted to the fence.

Figure 5 represents one of the hinges of the lid, with the cylindrical rod (10) inside a sheath square section (12), screwed to the box inside the sheet. The key (14) for fixing the rod is also watch

Figure 6 shows the elevation of the assembly of the fence (1) and sheet (2) with corresponding sections transverse and longitudinal.

Figure 7 shows the detail of the section A-A of Figure 5 in the drive zone of closure (11), where it can be seen that it is embedded in the stringer (5) of the fence by the closing hole (6), blocking the opening. This figure shows the two orthogonal steps that forms the fence, the exterior and the interior, by means of which It fits perfectly to the blade.

Finally, Figure 8 is a view of the lid perspective mounted. Check that the surface of the set  sheet (2) and fence (1) is completely flat and aligned with the wall where it is located.

Execution mode

The registration cover developed as the first function must be approved with "RF" classification, fully protected by current regulations on resistance to fire. Therefore, all constriction materials are products  last generation

Thus, the sheet used for the formation of the sheet has been chosen based on the following criteria: Coverage  Iron-Zinc alloy of at least 100 gr / m2 to protect the product against possible sources of moisture and against Corrosion, steel grade suitable for folding and stamping of the material, without reaching the breaking point, star killed for ensure a smooth surface without roughness, and multimeter of external treatment that allows the direct application of enamels of termination

The filling of the sheet is formed by high density insulations created for direct application against fire, among which stand out:

a) Glass wool, formed from rock basaltic and commercialized in panels of thickness 40 mm. At manufacturing process melts the stone up to temperatures higher than 1,600 ° C. Liquid rock becomes fibers by a spin process and by binders and oils are formed these panels that can have a density of up to 180 kg / m 3.

b) The plasterboard. From the formation of Conventional walls the idea of moving these panel coverings with paper support that after many studies they derive in special products for fire fighting. Combined with the Rock Wool, it provides sufficient moisture when it comes to withstanding the scourge of the heat of a fire to momentarily refresh the whole.

c) The intumescent board. In those spaces where the definitive seal is not possible because it is a practicable element, this product is used, which has evolved in an important way during the last years, creating flexible joints capable of multiplying by twenty their thickness, activating with relatively low temperatures. This composed of a graphite base and other binders.

Building

The manufacturing process of the covers of Registration conceived is, in short, the following:

For the construction of the fence is part of the Galvanized steel sheet with the desired width. Then you drill holes for the axis of rotation in two headers and the closure on a crossbar. Then the folded over the sheet to form the anchor claws and the steps presented by the stringers and headboards.

Then proceed to miter cutting of the stringers and headboards with the desired size. Once you have the parts of the fence, the assembly and recessing of the stringers and headboards, with subsequent sealing by gasket intumescent, indispensable element in fire doors, designed to prevent the passage of the flame.

Finally the squares are placed and painted or panela with the desired color.

For the construction of the sheet is part of the insulators and galvanized steel sheet, in addition to the system of hinge and closing drive. First the cut is made of the sheet steel with the dimensions of the box and the lid of the sheet, followed by drilling through a hole where appropriate in the holes for the stems and the one for the closure. Then you perform the folding of the sheet to form the box and the lid of the  sheet, with the subsequent sealing by intumescent gasket of the gaskets that present the box and the lid.

Then the hinge system and the closing drive to the box by screwing. The box and the cover is filled with insulating materials, such as wool rock and plasterboard, superimposed for proper performance.

Then proceed to assembly and joining by pressure from the box to the lid and finally the paint is painted or lined visible part with the desired color.

For mounting the sheet in the fence, it is placed the leaf in the fence introducing the ends of the two stems in the holes made in the step outside the fence, and fix the stems by screwing.

Installation

The installation of the cover on the spaces where it is required it is very simple, and the fence must be placed on the pre-installation of pre-installation on the wall, so that it is flush with it. The fence is embedded in work, fixed with sideburns.

The termination of product delivery to Installer can be the basic one, in galvanized sheet with "antifinger" termination, which carries an emulsion for the direct application of the enamel and that allows the manipulation without fingerprint or grease marking, or with final finishes such as baked enamels, pre-lacquered, etc.

Once the invention has been described, with its components referenced to the drawings with sufficient clarity to carry out its production and operation, it is declared as new and of his own invention, making the exception that his details, size, materials, manufacturing procedures and applications may be modified with respect to what is described and represented herein, always within the unaltered essentiality that is summarized in the following:
