Description

  The present invention relates to a metal ceiling foundation structure for a ceiling element comprising crossed metal beams spaced from the ceiling. In this respect, the metal beams form a lattice and are configured in the form of main beams and cross beams. The connection of the metal beams to each other is in this respect by means of specially configured connectors that engage into openings arranged in the web region of the metal beam and lock the individual metal beams to each other. It has been realized.

Metal ceiling foundations with crossed metal beams spaced apart from the ceiling and forming a grid for the ceiling element are known in the prior art.
Such a metal ceiling foundation structure is described in US Pat. No. 6,199,343 B1. In this basic structure already known from the prior art, the grid is likewise formed by locking the main and transverse beams. In this respect, the main beam and the cross beam described therein are formed in the shape of a T-shaped cross section. Locking has heretofore been performed by a connector that is disposed on the end face of the metal beam and engages through an opening that is disposed in the web region of the metal beam. In this respect, the opening of the T-shaped beam is formed in a specific rectangular shape. However, it has now been shown that the locking of the connection by the opening described in US Pat. No. 6,199,343 B1 takes time. Furthermore, even if it is desired to release the lock again, it is difficult to release it.

  Another comparable system is disclosed in US Pat. No. 4,779,394. According to this US patent, it is proposed to form a metal ceiling foundation structure that locks the main beam and the transverse beam via a connector. U.S. Pat. No. 4,779,394 certainly provides a special design for the opening of the web region of the metal beam, but the interlocking of the two transverse beams with the main beam is still cumbersome and time consuming Eat. Release of a locked connection is also not easy.

  Similarly, a T-beam consisting of a web and a flange that can be used for a metal ceiling foundation structure is described in WO 2009 / 087378A1. In the above mentioned WO patent specifications, it is proposed in this respect to introduce reinforcing ribs in the web region in order to reinforce the material.

US Pat. No. 6,199,343 B1 U.S. Pat. No. 4,779,394 WO Patent No. 2009 / 087378A1

  Starting from the above, an object of the present invention is to provide a metal ceiling foundation structure for a ceiling element, in which individual metal beams, that is, main beams and cross beams can be easily and reliably locked to each other. Is to provide. A simple separation of the locked connection should also be possible with a solution that can be found. A further object of the present invention further includes proposing a connector that ensures the secure locking of the individual metal beams to one another while being as simple as possible in design.

This object is achieved by the features stated in claim 1 of the claims. The dependent claims present advantageous further developments.
According to the present invention, a metal ceiling foundation structure for a ceiling element is proposed which comprises crossed metal beams arranged spaced apart from the ceiling and forming a grid. In the ceiling foundation structure according to the present invention, the metal beam is configured as a main beam and a horizontal beam, and at this point, it has an inverted T-shaped cross section in which its flange is aligned in the interior of the room. The intersections of the lattices are formed by connecting members that are disposed at the end portions of the end faces of the cross beams and are locked to each other through openings in the web region of the metal beams.

  In the ceiling foundation structure according to the present invention, the metal beam has an opening having a rectangular basic shape, and the protrusions extend in the direction toward the inside of the opening, and the center of the short side of the rectangle and the long side of the rectangle. It is important that they are formed individually at the same height. These specially configured openings then cooperate with a connector as proposed by the present invention, i.e. with a connector having a respective overhang on each longitudinal side.

  With such a structure, it is now possible to ensure reliable and simple locking of the metal beams to each other. Furthermore, it has been found that easy and trouble-free separation of the beams from each other is also possible with a specific configuration of the openings and connectors. Furthermore, it has been found that a much improved stability and strength is achieved by the particular construction of the connector having an overhang that forms an omega shape when the metal beams are locked together. It has also been found that torsional rigidity is significantly improved by using such an “omega type connector”.

  In the solution according to the invention, it is further advantageous that both the projections, ie the projections on the short side of the rectangle and the projections arranged on the long side, are machined from the material of the metal beam itself. As a result, the protrusions can be simultaneously formed by a simple production process in the manufacture of the metal beam.

In this respect, it is preferable that the long-side protrusion is formed in the upper region far from the long-side flange surface.
In this respect, the projections are particularly preferably arranged on the upper third of the long side, very particularly preferably on the upper quarter, particularly preferably on the upper fifth. In this respect, the protrusion and the opening itself are of a size suitable for guiding a connector guided through the opening. According to the invention, the size ratio of the rectangle is thus adjusted directly with the connector.

  The connecting device itself is fastened at this point to the end face of the cross beam via at least one connecting device, preferably via a press-fit connection and / or rivet, as is known per se. . Therefore, the connection tool fastened to the end face end portion of the cross beam protrudes beyond the end face end portion of the cross beam as a matter of course. In this regard, the connectors are coordinated with each other with respect to their sizing and their design so as to co-operate with the openings in the web region of the metal beam. In this regard, it is important that each connector has an overhang that cooperates with the protrusion on both sides of the long side.

  In principle, the specific form of the connector in the sense of the invention is not limited. According to the present invention, in this respect, the connecting device may be configured as either a hook-type connecting device or a click-type connecting device as long as it has the above-described omega-shaped overhang.

  The hook-type connector that can be used according to the invention is designed in this respect so that the connector itself has two openings, both of which are configured to partially protrude beyond the end of the end face of the web region. Has been. The two openings are designed in this respect to be planar or, preferably, the first opening, in fact the opening facing the end of the end face of the web region is substantially rectangular It can be either shaped and designed to form an outward arch. In this respect, the second opening is configured such that each arched opening of the other connector of the transverse member can be engaged into the second opening. This provides further stabilization of the locking connection.

  The hook-type connector described above is further characterized in that it has an arcuate recess and an additional nose in the overhanging region that is actually far from the flange surface. This particular design of the arcuate recess with the nose ensures that the locking connection in the locked state can be easily released. Thus, if one rail, preferably the main beam, is pushed to the side, the nose is released from its contact point, and the transverse beam can then be pulled out through its opening. The hook-type fitting with a hook at the free end proposed in accordance with the present invention thus has an omega shape and has an arcuate recess next to the nose of the overhang region. It is a feature.

  However, as already explained, the present invention in this respect used other designs, i.e. designs with one opening of the connector, or likewise two openings, each of which is planar. It also has a design. The present invention also includes an embodiment in which the connector has no opening.

  However, according to the invention, not only can the hook-type connectors described above be used to lock the cross beams to the main beam or to lock the cross beams to each other, but the locking is further performed by so-called click-type connectors. You can also Such click-type connectors are known in the prior art in principle. However, according to the invention, it has now been proposed to use a click-type connector which again has the omega shape already described above for the hook-type connector. Therefore, the click type connector according to the present invention has the above-described overhang so that the omega shape of the click type connector is formed, and a spring is disposed in a region extending between the two overhangs. It is characterized by. The spring design itself is known in the prior art. However, as explained above, the difference from the prior art is that the click-type connector has an omega shape due to the overhang.

  Due to the specific design by the combined use of the omega-shaped connector proposed by the present invention and the projection of the opening, the same type of connector such as click-type connectors or hook-type connectors is used for locking. In addition, the click type connector is arranged at the end of the end face of the cross beam, and the hook type connector is arranged at the end of the other end face of the second cross beam. This can be realized this time. Locking between these two different connector types is also ensured by the omega shape.

  In the metal ceiling foundation structure according to the present invention, as explained above, the locking is carried out in this respect between the two transverse beams and the main beam using the above-mentioned connection tool. In this respect, the metal ceiling foundation structure according to the invention takes the measure that the cross beams can also be locked together as already known in the prior art. In this case, the cross beam also has an opening in the web area as described above. Locking is then effected on the two further cross beam counterparts using the connections described above. As already established as known in the prior art, such a system results in the construction of a grid. In connection with such a grid, it is important that a ceiling plate having a standard size manufactured by the industry can be stretched to the corresponding grid. For this purpose, according to the invention, the main beam is 3 m to 4 m long, preferably 3.6 m or 3.75 m, and the transverse beam is 0.5 m to 2.0 m long, preferably Has a length of 0.6 m to 0.625 m and a length of 1.2 m or 1.25 m.

  The metal ceiling foundation structure according to the present invention still further connects the connection of the cross beam to the main beam or the connection of the two cross beams to another cross beam by the opening arranged in the web region at the intersection. It is characterized by being able to be formed so as to be connected. In this case, the end face end portion of the flange of the cross beam abuts on the long edge of the flange. Thereby, the flushness in the direction of the living room is realized.

  Nonetheless, the ceiling foundation structure according to the invention is further designed such that the end face of the cross beam has a crank so that it engages the flange of the main beam or likewise on the flange of the cross beam. Thus, reliable holding may be ensured.

  Also, another particularly preferred embodiment proposes that there be each protrusion machined from the material of the cross beam for a reliable connection to the main beam of the cross beam or to each other. ing. This protrusion then engages on the main beam or cross beam flange in the locked state and provides additional stability.

  The advantages of this solution also include the fact that this protrusion can be machined from the material of the transverse beam in a single machining step simultaneously with the production of the transverse beam. The protrusion protruding from the web of the cross beam is therefore an integral component of the cross beam. The length and sizing of the transverse beam protrusions are adjusted so that a positive engagement is achieved when engaging the protrusions on the main beam or even above the upper surface of the flange of the transverse beam. In particular, this variant has proved to be suitable on the one hand because it is inexpensive to manufacture and furthermore allows a reliable and stable locking. This solution for the protrusions has the further advantage that no barking occurs when releasing the locking connection and the locking connection can be released again in a simple manner.

  In the structure according to the invention, the T-beam is preferably formed from a double plate. The manufacture of such a T-beam is thus such that a planar metal plate is produced by a specific forming process, preferably with a web length in the range 20 mm to 80 mm and a flange width of 10 mm to 70 mm. It is done by molding into. As already known in the prior art, in the ceiling foundation structure according to the present invention, the end of the web surface of the T beam has a hollow portion, preferably a rectangular hollow portion. Is preferred. In the ceiling foundation structure according to the present invention, a measure may be taken in which the double plate is connected to the end of the flange surface of the T-beam via an additional metal terminal metal plate. Moreover, this termination | terminus metal plate has a visual effect by the side of a living room, and should just be comprised according to a desired design. In addition to the visual effect, this termination metal plate also has the advantage of providing additional stability of the flange face end of the T-section.

  In this respect, the T-beams used according to the invention for the main beam and the transverse beam are additionally formed such that at least one linear reinforcing part is preferably present over the entire length of the web region. May be. This reinforcing part may be pressed, for example, into a rectangular metal. The present invention also includes embodiments in this regard where more than one reinforcing portion, for example two or three reinforcing portions, are processed in a form parallel to the web region.

  In order to further improve the rigidity of the beam system, additional reinforcing ribs may be pressed in the area of the flange end of the web area of the main and transverse beams. These reinforcing ribs may be processed in the form of a dot or short line in the region of the flange side end of the web region. These reinforcing ribs are usually similarly linear and extend parallel to the flange. In this respect, the reinforcing ribs are preferably introduced into the web by a two-stage process. In the first process step, the lug is separated from the material in this process. Then, in a second process step, the stamping is performed so that a flow of lug material occurs. The press thus ensures that the lug is never pushed back into the cut-out. According to the present invention, such a design of the reinforcing rib according to the present invention is suitable, since a great improvement in torsional rigidity can be achieved especially if such a design of the reinforcing rib is used.

  Thus, pressing from one side of the side of the web region to the other is caused using the method described above for pressing the reinforcing ribs. It is still preferred if these reinforcing ribs are not only pressed in the direction from one side of the side to the other, but rather if some of the reinforcing ribs are pressed from the opposite side. Is now known. In this respect, it is preferable that the reinforcing ribs preferably arranged in a linear form are alternately pressed from one surface to the other direction. It has been found that a further improvement in stiffening and anchoring for torsion of metal beams, which can reach up to 2 m, is realized in particular by this embodiment. This embodiment will of course be combined with the further possibility of additionally having a linear reinforcement as described above. In addition, the reinforcing ribs are alternately pressed from one direction of the flange end to the other, then parallel to it in the direction of the hollow part at the web end and also in one direction alternately with further reinforcing ribs. An embodiment in which the reinforcing ribs processed in the other direction are additionally pressed is preferred. In this respect, the reinforcing ribs arranged at the web side end may be widely separated from each other.

  Naturally, the invention is an embodiment in which, for example, two reinforcing ribs are arranged in a linear configuration parallel to the flange, and the above-mentioned reinforcing portion additionally exists in the linear configuration as described above. Also included.

  In the present invention, as known in the prior art, a measure is taken that the main beams are connected to each other via a so-called bayonet joint. Therefore, the connection between the main beams to each other is the connection at the intersection point mentioned above, that is, the lattice is formed by the main beam and the two horizontal beams or from one horizontal beam and the two main beams. The connection is done differently. These intersections are realized only by special connectors, as explained above.

The material of the metal beam is a steel plate from a cold rolled strip. Steel types include integrated carbon steel with carbon in weight proportions up to 1%, a suitable steel plate is DX51Z100.
The material for the connection is stainless steel, such as a chromium-nickel alloy, such as X10CrNi18-8 (AISI 301).

In the present invention, it must be particularly emphasized that the combination of stainless steel material selection and omega shape provides an extraordinary mechanical stability.
In the following, the present invention will be described in more detail with reference to FIGS. 1 to 9, but the scope of protection is not limited to these specific embodiments.

The protrusion is machined in this respect from the material of the metal beam itself and is therefore an integral part of the metal beam. As a result, the protrusions 2, 3, 4, and 5 are provided with the same material as that of the metal beam. As a result, the protrusions 2, 3, 4, and 5 can be produced in a single processing step, so that simple and inexpensive production is possible. What is important for the solution according to the invention is the specific configuration of the opening 1 of the metal beam. The arrangement of the long side projections 4 and 5 is in this respect such that they are arranged in the upper third of the opening 1, preferably in the upper quarter, and that they are on the fitting. The shape is selected so that a specific shape is supported by the protrusion.

  Next, in FIG. 2, the design of the metal beam, ie both the main beam and the cross beam, is shown in cross section. In this respect, the metal beam according to the invention comprises a double plate which is correspondingly formed by molding. The end of the web 32 opposite to the flange 31 is formed in the shape of a hollow portion 9 having a rectangular shape. The example shown in the embodiment of FIG. 2 additionally has a reinforcing part 7 in the web 32. This reinforcing part 7 is likewise formed by double plate molding and provides additional stiffening in the web 32 of the T-beam. In this respect, the reinforcing part 7 is preferably formed over the entire length of the web 32. In this respect, the present invention also comprises an embodiment in which two or three parallel linear reinforcing portions 7 are introduced into the web 32.
