Description

The invention relates to a method for connecting at least two elements to the

  means of a coupling part in which the elements to be assembled are provided with at least one assembly profiling, and the assembly profiles are arranged to be substantially oriented towards each other, and then the coupling part provided with

  counter-profiling in the vicinity of the assembly profiles.

  In addition, the invention relates to a connecting device of at least two elements which is carried out mainly as a coupling piece in the form of coil engaging counter-profiling element in profiling connection elements. Such known coupling parts are produced in the form of a mechanically strong profiled bead and are made of, for example, iron or aluminum. To assemble two elements which are provided with corresponding connecting profiles, the coupling piece is introduced transversely into a predicted load direction, with its counter-profiling in the element connection profiles By a positive engagement between the connection profiles and the counter-profilings, an unintentional separation of the elements is prevented. The connection profiles, to ensure an assembly simple, also extend

  transversely to a predicted load direction.

  Another elementary method for connecting two elements by means of a coupling part is to make the connection profiles as bore hole tapping and counter-profiling as corresponding external threads of bolts. In this embodiment, the coupling piece can be configured as a flat profile or a double-T profile. However, the known methods and connection devices have the disadvantage that the implementation of the connections requires a considerable working time, which can avoid cold bridges only with additional expense, and that one can not or only with considerable expense undo the links for

  replacing one or more elements.

  The present invention therefore relates to the improvement of a method of the type indicated at the beginning which allows to perform the necessary work in a reduced time. This object is realized according to the invention in that the coupling part is made, at least in zones, of an elastically deformable material, and that it is provided with at least one evacuable inner space, which before assembly of the elements, the interior space is biased under vacuum, and after an arrangement of the coupling piece in the vicinity of at least one of the connecting profiles, is introduced into the interior space

a fluid.

  Another object of the present invention is the improvement of a device of the type indicated at the beginning of the present invention.

  to allow easy handling during use.

  This object is realized according to the invention in that the coupling piece is made at least in zones of elastically deformable material and has at least one hollow space which can be evacuated which is provided with a connection for the connection to a vacuum apparatus, and that the hollow space for the separation of the connecting profilings and the counter-profiling during the vacuum bias has a cross-sectional area

  which can be reduced by depression.

  This combination of features makes it possible in a simple manner to urge the coupling part before the elements are assembled by a depression and thus to cause an elastic contraction assembly. In this state, the coupling piece is inserted into the elements to be assembled. in the vicinity of their connecting profilings so as to occupy the planned relative provision of the building elements Then the vacuum stress is terminated. When the coupling piece is sufficiently elastic, the latter automatically resumes its shape.

  counter-profiling in the elements linking sections.

  In a less elastic embodiment of the coupling piece, it can be reduced by means of a compressed air supply in its initial form. The vacuum supply can take place by means of valves made in such a way that However, it is also possible to provide one or more recesses in the vicinity of the coupling piece and to achieve a sufficient seal, for example by a pressure of application of a connecting piece The elements to be connected can be arranged, for example, facing each other or at a right angle. A particularly simple connection of the connection and counter-drilling operations can be carried out in that the coupling piece, after it has been evacuated and before a supply of the fluid, is placed in a receiving chamber which at least by Link profiling areas. The vacuum created in the interior space of the connecting profile can be removed simply by sending to

  the interior space of the ambient air.

  In order to increase the tightness of the undercuts as well as for the provision of a larger bond by force it is proposed to put the interior space in

surpress ion.

  The mechanical strength is increased, in particular during the introduction of external torsional forces, in that, in addition to a connection of the elements by the coupling part, a complementary rigid connection acting in a substantially parallel manner is installed. the room

coupling.

  An embodiment of a container easy to assemble and disassemble is made possible by the fact that the coupling parts together with angular connecting elements constitute a frame forming a structure

  support for the walls of a container.

  Easy assembly of sealing elements is ensured in that at least one of the coupling parts is realized

by a seal.

  It is proposed in particular for use in the field of refrigerated containers or for use in the field of containers that carry products to be protected from condensation water, that the coupling part performs thermal insulation of the elements to be cooled.

connect one to the other.

  An appropriate influence of the areas of the coupling part which undergo a large deformation during a depression is made possible by the fact that the coupling part is formed as an angle profile which has external support legs which have a greater wall thickness than a connecting wall provided between their ends remote from each other and which

constitutes counter-profiling.

  A particularly useful configuration is obtained in the production of corner profiles in that the connecting wall extends in a substantially circular outline.

form of w.

  A regular decrease of the cross-section in the vicinity of two partial parts, made respectively as connecting elements, of the coupling part is made possible by the fact that the W-shaped shape is made from two outer curvatures which are

connected by a median branch.

  Additional support for deformation of the part

  mating in the vicinity of the areas constituting the

  profiling is made possible by the fact that an angle formed by the support legs is provided in the vicinity of its extension oriented towards the inner space of a corner reinforcement. To provide a parallelepipedic support structure for receiving plate-shaped elements, it is proposed to produce from the coupling parts as well as angular connecting elements interconnecting the coupling parts, a frame which is built as a support structure for elements in

form of plates.

  An embodiment suitable for use in the vicinity of two contiguous elements is made available in that at least one of the coupling parts is in the form of a sealable sealing element.

  under vacuum with an oval contour in cross section.

  To allow use in the vicinity of elements guided simply sealingly against each other, it is proposed that at least one of the coupling parts is made in the form of a seal with profiling

lamellar reported.

  Inexpensive manufacture of the coupling part in large quantities is made possible by the fact that the

  coupling piece is extruded in the form of a coil.

However, a connection profiling 49 disposed in the vicinity of one of the flaps of FIG. door 42 is made more flat relative to the bonding profiling 46, to allow a simpler opening of the door leaves 42 without causing in this case

  damage in the vicinity of the coupling part 3.
