Definitions

• the invention relates to a connecting element for mechanically connecting components or the like. With the features of the preamble of claim 1.
• connecting elements are known for example from DE 10026 769 A1.
• a coupling half is fastened to each of two components to be connected or the like by means of screws.
• the coupling halves are engaged to connect the components.
• they have a centering device with wedge-shaped or conical engagement elements.
• Coupling halves are also arranged line connection elements for water, gas, electricity or the like, so that a media connection is simultaneously established in the mechanical connection.
• the fasteners For extremely heavy components, such as. B. walls in prefabricated houses, the fasteners must absorb very high loads. Due to unevenness in the floor slab, it can happen that a complete wall is carried by two neighboring walls when installed. In addition to these weight forces, there are considerable inertial forces and shocks when assembling the prefabricated house walls. Basically, the time required for assembly plays an important role. Due to the complex structure of the known fasteners, which can only be economically shaped in plastic or
• the invention has for its object to provide a highly stable connecting element that allows quick assembly of the components to be connected, especially in combination with the connecting elements known from DE 10026 769 A1.
• the coupling halves have pipe sections that are due to different cross sections are nestable.
• standardized square tubes made of steel can be used.
• the term “pipe sections” is synonymous for all parts whose cross sections are suitable for longitudinal guidance, that is to say, for example, also the combination of a flat steel, I, C or T profile with a pipe section, which of course also has a longitudinal slot can have according to a profile rail or can be reduced to one or more eyelets.
• tongue and groove cross-sections are included which are suitable for longitudinal guidance due to an undercut. Rolling or lubrication systems can support this guiding property.
• the pipe sections are arranged at an angle to the contact surface of the components.
• the insertion path is not limited by the coupling halves, but ends as soon as the components touch with their contact surfaces.
• the coupling halves are arranged on the components in such a way that the coupling half is fastened to the fixed component with an obliquely upward tube piece, while the other component to be joined has a tube piece pointing downward.
• the gravity of the component to be joined can be used. Due to the oblique arrangement of the pipe sections, the components are positively guided and finally sit snugly against one another with their contact surfaces.
• connecting elements that provide a joining direction perpendicular or parallel to the contact surfaces, there is the advantage that the components do not have to be braced separately after joining. If the connecting elements according to the invention are used in combination with the connecting elements known from DE 100 26 769 A1, the result is another
• the connecting elements according to the invention absorb the weight and joining forces during and after the joining, while the connecting elements from DE 100 26 769 A1 are relieved and can therefore be designed to be weaker. Due to the positive guidance of the connecting elements according to the invention, the connecting elements from DE 10026 769 A1 are also moved towards one another in such a way that their centering devices at most bring about a slight compensating movement combined with low forces.
• the pipe section with a smaller cross section has an insertion cap. Due to the resulting bevels, the Join the coupling halves easily even with very rough positioning options. This is important, for example, when connecting walls in prefabricated house construction, since very large wall elements may have to be attached to a crane.
• the coupling halves have wedge-shaped bases, for example made of plastic, for carrying the pipe sections obliquely on the components, which support the pipe sections.
• the coupling halves are fastened to the components using screws.
• the screw heads come to rest on the inside of the pipe sections facing the component and extend through the
• an embodiment of the invention has an adjusting element between the pipe pieces with displacement means transverse to the longitudinal direction of the pipe pieces.
• the adjusting element preferably has a sheet-metal strip bent in the form of a cap, which in addition to the adjusting function also has a joining function in the sense of the insertion cap mentioned above.
• Moving means two bolts with a thread are proposed, which are supported, for example, by a slide bearing in the sheet metal strip and whose threads engage in threaded bores of the inner tube piece.
• the bolts can be rotated by means of externally arranged tool engagement means, such as, for example, a hexagon socket. By turning the bolt, the adjusting element moves relative to the pipe section.
• a preferred embodiment of the invention has an attachable force direction sensor. This is arranged on the outer pipe section in such a way that the inner pipe section, which rests in the area of the force transducer, transmits forces where the outer pipe section can best accommodate them, for example, at its end facing the inner pipe section.
• the force direction sensors are preferably simple sheet metal parts bent in a U-shape.

• the connecting element 1 shown in FIG. 1 serves to connect the two components 2 and 3, for example two walls to be connected in a prefabricated house. It consists of the two coupling halves 4 and 5, which are fastened to the respective component 2, 3 by means of screws 6. Both coupling halves 4, 5 each have a pipe section 7, 8, which are supported by wedge-shaped bases 9, 10 made of a high-strength plastic.
• the pipe sections 7, 8 are standardized square pipes made of steel, which have a different cross section and can be plugged into one another.
• the coupling halves 4, 5 are first attached to the components 2, 3 by means of the screws 6 as part of a pre-assembly.
• the screws 6 are inserted through the recesses 11 and finally come into contact with their screw head 12 on the inner sides 13, 14 when screwed in.
• the insertion cap 15 is used to form bevels.
• FIG. 2 shows the pipe sections 7a, 8 of a second embodiment in section.
• An adjusting element 17 is arranged between the pipe sections 7a, 8.
• the Adjustment element 17 has a cap-shaped sheet metal strip 18 and two displacement means designed as bolts 19.
• the bolts 19 have a thread 20 and an internal hexagon 21 on both sides as a tool engagement means. They are each stored in bores 22 of the sheet metal strip and engage in threaded bores 23 of the inner pipe section 7a. As long as the raw pieces 7a, 8 are not yet in engagement, the bolts 19 can be rotated in parallel and thereby the sheet metal strip 18 can be displaced transversely to the longitudinal direction of the inner pipe piece 7a. Since the adjusting element 17 is in turn inserted into the outer tube piece 8, the offset A of the central axes shown can be set in a targeted manner, for example.
• Figure 3 shows a further embodiment of the connecting element 1b according to the invention. It consists of the two coupling halves 4b and 5b. Both coupling halves 4b, 5b each have a pipe section 7b, 8b, the pipe section 7b being designed as a flat steel with insertion bevels 24. The pipe sections 7b, 8b are in turn supported by wedge-shaped bases 9b, 10b made of plastic. Force transducers 26 in the form of sheet metal parts bent in a U-shape are attached to the edges 25 of the outer tube section 8b facing the other coupling half 4b. These have the effect that the forces acting between the coupling halves are transmitted in their immediate vicinity and in this way in particular greater leverage effects are avoided.
