Definitions

  • the invention relates to a metallic ceiling substructure for ceiling elements, which consists of intersecting, spaced from the ceiling metal beams.
  • the metal supports form a grid and are in the form of main and transverse beams.
  • the connection of the metal support to each other is realized by specially designed connectors, which engage in openings which are arranged in the web region of the metal support, and engage the individual metal support with each other.
  • the prior art prior art substructure is also a grid formed by locking of main and cross members.
  • the main and transverse beams described therein are designed in the form of a T-profile.
  • the latching takes place here already by connectors, which are arranged on the front sides of the metal carrier and by an opening which is arranged in the web region of the metal carrier, engage.
  • the opening in the T-beams is formed in a special rectangular shape.
  • WO 2009/087378 A1 a T-beam of a web and a flange described, which can also be used for metallic ceiling substructures.
  • US3501185A describes all the technical features of the introductory part of the first claim. Proceeding from this, it is the object of the present invention to provide a metallic ceiling substructure for ceiling elements, in which the individual metal support, ie the main and cross members, are locked together easily and safely. Also should be possible by the solution to be found easy separation of the latched connection.
  • a further object of the present invention is also to propose a connector which is as simple as possible in construction, which nevertheless ensures reliable latching of the individual metal carriers to one another.
  • a metallic ceiling substructure for ceiling elements, which consists of intersecting, spaced from the ceiling metal beams, which form a grid.
  • the metal beams are formed as a main and transverse beams and consist of an inverse T-profile, the flange is aligned in the direction of the interior of the room.
  • the crossing points of the grid are formed by connectors which are arranged at the front ends of the cross members and which are latched to one another via openings in the web region of the metal carriers.
  • the metal supports have an opening with a rectangular basic shape, with projections in the direction of the interior of the opening being formed centrally on the short sides of the rectangle and on the longitudinal sides of the rectangle at the same height are.
  • These specially designed openings then act together with the connectors as they are proposed according to the invention, namely with connectors which have respective bends on their longitudinal sides.
  • a further advantage of the solution according to the invention is that the projections, ie the projections both on the short side of the rectangle and those which are arranged on the longitudinal sides, are machined out of the material of the metallic carrier itself. As a result, in a simple production process, the protrusions can be formed simultaneously with the manufacture of the metallic supports.
  • the projections are formed on the longitudinal side in the upper region facing away from the flange side. These projections are on the long sides in the upper third.
  • the projections and the opening itself are then dimensioned so that they are suitable for guiding the connectors passing through the opening.
  • the size ratios of the rectangle are thus matched directly to the connector.
  • the connectors themselves are, as known per se, attached to the front ends of the cross member via at least one connecting device, preferably a compression and / or rivets.
  • the connectors, which are attached to the front ends of the cross member, then protrude beyond the front end of the cross member, of course.
  • the connectors are matched in their dimensioning and design so that they work together in combination with the openings in the web area of the metal support.
  • each connector has a fold on both sides of the long sides, which cooperates with the projections.
  • the specific form of the connector is not limited in the sense of the invention.
  • the connectors if they have the above-described folds in omega form, can be designed both as hook connectors and as click connectors.
  • the hook connectors which can be used according to the invention, are constructed so that the connector itself has two openings, both in the front end of the web area superior part are formed.
  • the two openings can either be flat, or, which is preferred, be formed so that the first opening, namely the one which faces the front end of the web, has approximately rectangular shape and is arched outwardly.
  • the second opening is designed so that in each case the bulged opening of the other connector of the cross member can engage in the second opening.
  • the hook connector as described above is further characterized in that it has an arcuate recess and an additional nose in the folded portion, on the side facing away from the flange side.
  • This specific design of the arcuate recess with the nose ensures that then in the locked state easy release of the locking connection is possible. Namely, when one of the rails, preferably the main carrier is pushed aside, the nose releases from its support point and the cross member can then be pulled out through its opening.
  • the inventively proposed hook connector which has a hook at its free end, thus characterized by the fact that he also has omega shape and that he next to the nose has an arcuate recess in the folded portion.
  • the invention also encompasses other embodiments, namely by means of an opening in the connector or else two, which can each also be planar. Also, the invention includes embodiments that are formed without opening in the connector.

  • the click connector also has an omega shape due to the folds.
  • latching takes place by means of the above-described connectors between two transverse beams and the main beam.
  • the transverse beams may in turn be latched to one another.
  • the cross member in the web area on the opening described above then also have the cross member in the web area on the opening described above.
  • a latching then takes place with two other cross members with the connectors described above.
  • the main carrier 3 to 4 m long preferably 3.6 m and 3.75 m
  • the cross member has a length of 0.5 m to 2.0 m, preferably 0.6 m to 0.625 m and 1.2 m and 1.25 m, respectively.
  • the metallic ceiling substructure according to the invention is further distinguished by the fact that the connection of the cross members to the main carrier or the connection of two cross members with another cross member through the arranged in the web portion opening can be formed so that metal carriers are connected to each other via impact at the intersection points , In this case, thus abuts the front end of the flange of the cross member to the longitudinal edge of the flange. This achieves a flush transition towards the room side.
  • the ceiling substructure according to the invention can also be designed so that the front ends of the cross member have a crank, so that this offset then engage over the flange of the main carrier or the cross member, so that then a secure grip is ensured.
  • Another particularly preferred embodiment now proposes that for safe connection of the cross member with the main carrier or the cross member with each other at the front ends of the cross member ahoppedcetateer from the material of the cross member projection is present. This projection then engages in the locked state on the flange of the main carrier or the cross member and provides additional stabilization.

It has been found that especially this variant is preferred because it is inexpensive to manufacture on the one hand and also allows a secure and stable locking.
  • this solution has the advantage that there is no jamming when releasing the locking connection, so that the locking connection in a simple manner dissolves again.
  • the T-beam is preferably formed from a double sheet.
  • the production of such a T-beam thus takes place from a flat sheet, which is formed by certain forming operations so that a T with a web length preferably in the range of 20 to 80 mm and a flange width of 10 to 70 mm is formed.
