Description

The present invention relates to a mezzanine floor provided with an extension system in all its components, allowing its installation in any suitable place as well as changing location, the same structure being able to be adapted to other architectural spaces without needing to perform masonry works or changes in the structure.
The application field thereof is within the auxiliary components industry for construction and specifically in the auxiliary industry for mezzanine floors.
Effective developments specifically dedicated to the function in question, giving rise to a system that is easy to install, with low costs and technically considerable results take precedence in this technical sector. The features of the system presented in this invention are perfectly adapted to this concept, providing the state of the art with an embodiment that is novel, simple, and of a highly economical production cost.
Some models in this industrial sector which do not provide the state of the art with the novel features proposed by the present invention are known. The state of the art provides fixed mezzanine floors, custom-made according to the details of the location in which it is to be installed and another type of modular mezzanine floors consisting of fixed modules having preconceived sizes and which must be adapted to the location at the time of installation.
With respect to the novelty provided by the present invention, the known mezzanine floors have the following drawbacks: They can not be reused for other locations, for this reason in the event of moving to another place the installed mezzanine floor must be disregarded and a new one installed. Specialized staff is necessary for installing the known mezzanine floors. The transportation cost of these conventional mezzanine floors is greater than that proposed by the present invention, since it involves the use of trucks long enough to accommodate the components which have to have fixed measurements. More time needs to be dedicated to its installation. As they are made up of modules secured to one another, the modular mezzanine floors have firmness less than those proposed by the present invention. They are less versatile. Their installation is complicated. They are accompanied by masonry works.
Sending an operator to take measurements of the location where the mezzanine floor must be located implies the resulting economic cost. The manufacturing of these conventional mezzanine floors, due to the fact that it is necessary to produce them by units, is considerably more costly than those proposed by this invention. For the same reason an adequate stock cannot be kept, involving an increase in the service time.
WO 03/091514 A1 discloses a module-based building system comprising a set of pillars and beams of a fixed size, therefore presenting the drawbacks of the art as stated above.
The present invention relates to a mezzanine floor comprising a floor surface extended on beams supported by posts as defined in appended claim 1.
According to the invention, the mezzanine floor comprises at least four posts, at least two beams and at least two joists.
With respect to the drawbacks described above, the present invention provides novel, simple and easy to execute solutions to the state of the art, resulting in the following advantages:
They can be reused for other locations, disregarding the installed mezzanine floor and installing a new one in the event of moving to another place not being necessary. Specialized staff is not necessary for installing the mezzanine floor proposed by the present invention. The transportation cost is lower than that of those conventional mezzanine floors since the use of large vehicles is not necessary. The time dedicated to its installation is considerably lower. The mezzanine floor proposed by the present invention is firmer than that of the modular mezzanine floors. It is more versatile. Its installation is not complicated. It is not accompanied by masonry works. The deployment of an operator for taking measurements of the location where the mezzanine floor must be located is not necessary with the resulting economic savings. The manufacturing has a lower cost since it is able to be manufactured in series, because the measurements of its components are always the same. For the same reason an adequate stock can be kept, involving a savings in the service time.
All these combined elements give rise to a final result in which significant differentiating features are provided with respect to the current state of the art.
Thus the invention is made up of four posts made of steel or of a material with the same characteristics formed by telescopic tubes. A metal flat bar, which can be circular or another shape, with openings for securing it to the floor by means of screws, is preferably welded in an off-centered manner at the base of the lower tube, the largest area being oriented toward the inside of the structure and thus preventing the post from being too far away from the wall. The two tubes forming the post have coinciding holes which by means of a pin control the height of the structure. At the upper end of the post there is a capital, which can be made of the same material, formed by a flat bar bent essentially at a right angle, one of its sides welded to the post and the other side attached by means of screws to a beam described below. The flat bar bent essentially at a right angle which forms the capital has on the side welded to the post a reinforcing flat bar welded to the post and to the capital.
A beam made of steel or another resistant material the cross-section of which is rectangular-shaped is integrally attached by means of screws to the capital. One of the longer sides of the rectangle, outlining the section of the beam, has an aperture along the entire length of the beam large enough for housing a connector, formed by a plate which can be made of the same material as the previous components, bent essentially at a right angle. One of the sides of the connector is coupled by means of screws inside the rectangle formed by the beam, the other side of the connector is coupled in the same manner inside a joist, similar to the beam although having smaller size. On the side of the beam opposite to the side which is cut along its entire length, there are holes coinciding with the holes of the capital and of the connector, further having other larger holes acting as cable ducts.
The beams and joists are made up of two parts telescopically inserted into one another which, fixed by means of through bolts through their holes, will determine the width and depth of the mezzanine floor. Each beam is attached at its ends to a post, a beam and two posts forming an assembly and the mezzanine floor is formed by two assemblies, one front assembly and another back assembly, attached by means of the joists which in turn support the level floor, formed by sheets made of a hard material, screwed to the joists. The final floor is placed on this level floor according to the intended use of the mezzanine floor.
On the most convenient side of the structure there is a staircase made up of two stringers formed by extendable beams provided at their upper ends with a connector, formed by a plate bent two times at right angles, attached by means of screws, one side attached to the stringers and the other two sides attached to a beam or joist and to the level floor. The lower end of the beams forming the staircase incorporates other anchors formed by a flat bar bent at the suitable angle depending on the inclination of the staircase.
The landing steps made of a resistant material are attached by screws to the holes of both beams.
A different embodiment is manufactured with another type of material with sufficient resistance and rigidity to support the design load.
Another different embodiment is made up of more than four posts.
Another different embodiment incorporates polygonal-shaped posts or posts of another shape.
The base flat bar located at the lower end of the post is either polygonal-shaped or another shape.
The reinforcing flat bar of the capital located at the end upper of the post is either polygonal-shaped or another shape.
For illustrative purposes and not forming part of the invention, the section of the beams and joists are sigma-shaped, zeta-shaped, omega-shaped, u-shaped or the like.
Another different embodiment is made up of beams and joists of square-shaped section.
In other different form the mezzanine floor incorporates a side bar located on the upper portion.
The staircase has a side bar.
In another different embodiment, the staircase can be moved upwards, having the rotation shaft in its upper portion.
Alternatively the staircase is concealed under the beams of the mezzanine floor moving it horizontally towards the inside of the latter.
Without distinction, the staircase is secured by means of a leg which hangs from the lower portion of the staircase on one of its sides such that there is free passage below it.
In a different manner the staircase pivots toward one side having the rotation shaft in one of its stringers or in the support beam of the landing steps and the collapsible handrailings.
In another different embodiment the staircase is located inside the mezzanine floor, between two joists, opening up a hole on the floor of the upper floor for access.

A preferred embodiment of the invention is made up of four steel cylindrical posts 1 formed by two parts, upper post part 2 and lower post part 3, one fitted inside another, one located at the upper portion 2 and having a smaller diameter, which is slid inside the other 3 located at the lower portion and having a greater diameter, with the sufficient tolerance for allowing the sliding thereof. The lower post part 3 has at one end a round post base flat bar 4 made of the same material, with several holes, welded to the post in an off-centered manner. The lower post part 3 has at least two lower post part holes 5 at the same level facing one another located at the other end in which the post base flat bar 4 described above is located. The upper post part 2 having diameter smaller than that of the part post lower 3, has along its entire length and spaced from one another upper post part holes 6 similar to that of the lower post part 3. The height of the mezzanine floor is obtained by attaching the holes of the lower post part 3 with holes made in the upper post part 2 with a pin 34. At the upper end of the upper post part 2 having smaller diameter there is located a capital 7 made of the same material, formed by a flat bar bent at a right angle such that it has two faces vertical to one another, a capital face welded to the post 8 having width equal to the upper post part 2, is welded to the latter, the other beam securing face 9 having width equal to the beam 12, described below, has capital holes 10 coinciding with others made in the beam 12. On the outer part of this same beam securing face 9 there is at least one arc-shaped reinforcing flat bar 11, the flat part of which is jointly welded to the capital 7 and to the upper post part 2.
A rectangular-shaped beam 12 made of the same material as the previous components with a longitudinal beam section 13 on one of the longer sides of the rectangle made along its entire length with sufficient amplitude for housing a beam-to-joist connector 14 described below is attached to the already described capital 7 by means of screws. On the face opposite this longitudinal beam section 13 there are beam holes 15 along the entire length of the beam 12 coinciding with the capital holes 10.
These beams 12, like the posts 1, are made up of two beam parts 16 inserted into one another, with sufficient tolerance for allowing their sliding and which, fixed by means of through bolts through their holes 15, will determine the width and depth of the mezzanine floor.
A joist 17 of the same shape, material and composition as the beams 12, of the same length and somewhat having smaller cross-section, the extensibility of which controls the depth of the structure, is attached by means of screws to the aforementioned beam-to-joist connector 14 which is described below. Incorporated at each of its ends is a beam-to-joist connector 14 formed by a flat bar made of the same material as the previous components, bent at a right angle, two faces being perpendicular to one another. One of these faces, which is the joist-to-beam face 18 has the dimension sufficient to be coupled inside the rectangle formed by the beam and with the necessary beam-to-joist holes 19, coinciding with those made in the beam 12 and attached to the latter by screws. The other face, the connector face attached to the joist 20, has the measurements necessary to be coupled in the same manner as the above at the end of the joist 17. Each of its ends is coupled to the corresponding beam 12 by means of the beam-to-joist connector 14 described above, sufficient joists 17 being arranged along the entire length of the beams 12 for supporting the weight for which the structure is intended.
Each beam 12 is attached at its ends to a post 1, a beam 12 and two posts 1 forming an assembly and the mezzanine floor is formed by two assemblies, one front assembly and another back assembly attached by means of the joists 17 which in turn support the level floor 21, formed by sheets made of a hard material, screwed to the joists 17. The final floor is placed on this level floor 21 according to the intended use of the mezzanine floor.
On the most convenient side of the structure there is a staircase 22 formed by two extendable staircase beams 28 provided at their upper ends with a staircase connector 23, formed by a staircase securing flat bar 26 bent at a right angle, in which each of its faces it incorporates a slide hole 24 which is screwed to a beam 12 or joist 17 using the holes provided thereon and to the level floor 21. Another staircase connector flat bar 25 is incorporated to this flat bar and welded to the edge of one of its faces in the vertical direction, forming an angle greater than 90° with the previous one and determining the inclination of the staircase 22, this staircase connector flat bar 25 has welded flat bar holes 27 coinciding with the holes of the staircase beams 28 supporting and forming the staircase 22 to which they are secured by means of screws. The other end of the staircase beams 28 forming the staircase 22 incorporate staircase base connectors 29 formed by a flat bar bent at a right angle in which one of its faces, the base connector-to-beam face 30, is screwed to each of the staircase beams 28. The other face of the flat bar, which is the base connector-to-floor face 31, has at least one base connector-to-floor hole 32 whereby the staircase 22 is attached to the floor by an expansion anchor.
The landing steps 33 made of a resistant material are attached by screws to the holes of both staircase beams 28.
