Definitions

  • the invention is directed to a joining method for the permanent mechanical connection of two joining components with each other.
  • the invention is based on the object to provide a solution with which a with respect to the possibility of compensation of Fü foundedeilwashabweichitch improved and simplified joining method is provided.
  • this object is achieved according to the invention by a joining method for the permanent mechanical connection of two joining components with one another, which comprises the steps:
  • Cohesive and adhesive forces forming permanent and the forces occurring between the components transmitting connection.
  • Joining components is suitable, which should be precisely joined in a defined position to each other, their joining position and in particular do not have correspondingly accurate fitting and joining surfaces.
  • the necessary precision of the assemblies to be created from the two joining components is achieved by Alignment of joining components to be joined to each other and optionally necessary at least temporary fixing of the joining components in this joining position, for example by means of appropriate receiving devices, and the subsequent stress-free joining achieved by means of the first liquid and then curing joining medium. In this case, the joining position of the joining components during curing and thus then not changed in the cured state of the joining medium.
  • the method can be used in a variety of applications. Particularly advantageous, this method is suitable for cost-effective production of solar collector, whose efficiency depends crucially on the optical precision and thus on the precise alignment of the components of the mechanical collector structure to each other. As a result, it is possible to arrange the mirror elements and the support structure of a solar collector element precisely aligned with each other in a joining position and position and then permanently to connect firmly with each other, this attachment of the two joining components is formed free of tension with each other.
  • Parabolic solar collector consists of several collector elements, for example, have a Parabelö Anlagen Schluticae of about 6 m and a length of about 12 m.
  • the parabolic troughs are formed by mirror elements and in the focal line runs an absorber tube, on which the solar radiation is concentrated and to which the collected heat energy is released.
  • the precision with which the mirror elements are aligned with each other and the focal line, is essential, since it depends on the energy yield and thus the efficiency of such a solar thermal system. This precision is determined by the positioning and fixing of the mirror elements on the respective supporting structures of the solar panels.
  • the joining method according to the invention is a six-axis
  • Joining components namely in the joining surfaces having joining component, possible.
  • the joining medium which is advantageously a casting resin, such as polyester resin, polyurethane resin, silicone resin, vinyl ester resin, but especially an epoxy resin, no thermal stress by the hardening casting resin.
  • a possible joining medium is also hot melt adhesive.
  • a joining medium is used, which is preferably liquid at room temperature or in the range of ⁇ 100 0 C, or even in the range of ⁇ 200 0 C. To create the joint connection no joining forces must be applied. Also, no residual stresses are introduced into the joining components to be joined. Any existing corrosion protection layers of the joining components, such as a hot-dip galvanizing, remain intact when joining.

La présente invention concerne un procédé d'assemblage permettant d'assembler mécaniquement de façon permanente deux pièces à assembler l'une à l'autre. L'objectif de l'invention est de proposer un procédé d'assemblage qui soit amélioré et simplifié par rapport à la possibilité de compensation de variations dimensionnelles de pièces à assembler. Cet objectif est atteint par le fait que le procédé d'assemblage comprend les étapes qui consistent a) à aligner de façon exacte une première et une seconde pièce à assembler (1, 4) dans une position d'assemblage, avec formation d'un interstice d'assemblage (7) entre les surfaces à assembler (3, 3a; 6, 6a) des pièces à assembler (1, 4); b) à fixer au moins de façon temporaire les pièces à assembler (1, 4) dans cette position d'assemblage; c) à remplir l'interstice d'assemblage (7) d'un agent d'assemblage fluide (8) et d) à faire durcir l'agent d'assemblage (8) dans l'interstice d'assemblage (7) de manière à former une liaison permanente qui assure des forces de cohésion et d'adhésion et qui transmet les forces apparaissant entre les pièces à assembler (1, 4).
