Definitions

  • the present invention relates to a gable connection for connecting joining parts, a gable-connectable joining part and its production, a method for connecting joining parts and a use of a gable connection for connecting joining parts.
  • classic reinforced concrete ceilings have been used to date. Due to the steel reinforcements, these ceilings can absorb not only high compressive forces but also high tensile forces and are therefore particularly stable. Unfortunately, reinforced concrete ceilings also require a large amount of starting materials, particularly concrete, and also have a high dead weight.
  • the size of the FRC slabs is essentially limited by the transport of the slabs from the production site to the construction site, which limitation in turn is reflected in the maximum size of an FRC slab.
  • the present invention has set itself the object of providing an alternative connection for joining parts.
  • a further object of one aspect of the present invention is to provide a gable-connectable joining part.
  • a still further object of one aspect of the present invention is to provide an alternative method for joining parts.
  • a still further object of a further aspect of the present invention is to provide a use of a gable connection for connecting parts.
  • a still further object of a further aspect of the present invention is to provide a multi-part component, in particular a concrete component.
  • the negative gable-shaped section and the positive gable-shaped section are designed to be complementary in such a way that the positive gable-shaped section can protrude at least partially into the negative gable-shaped section.
  • the positive gable-shaped section projects at least partially into the negative gable-shaped section in such a way that one or more joints are formed between at least a part of the joining surface of the negative gable-shaped section and a part of the joining surface of the positive gable-shaped section.
  • the one or more joints are at least partially filled with a filler.
  • At least a part of the surface of the joining surface of the negative P220116 PCT and the positive gable-shaped section has unevenness in the range of 1 ⁇ m to 10 mm.
  • at least one of the at least one step of the first joining part has a width, a height, and an angle ⁇ , viewed from its upper side .
  • at least one of the at least one step of the second joining part has a width, a height, and an angle ⁇ , viewed from its upper side.
  • the angle ⁇ is greater than or equal to 90°, in particular greater than 90°, and more particularly greater than 90° and less than or equal to 110°, so that the height and width of the at least one step are not orthogonal to each other in a plan view of the upper side, and the at least one step tapers along its height and with increasing distance from its width.
  • the term "gable" originally comes from house construction and refers to the triangular surface in the roof structure. This refers to the wall section whose upper corner is the roof ridge and whose sides are the roof edges. The lower end of the gable triangle is the cross connection of the lower corners of the roof edges. This definition can ultimately be modified and applied to a joining part with a basic structure on which a projection is arranged, forming the gable.
  • the gable-shaped section according to the invention is not necessarily triangular, but can also have a different geometry, it is advantageous if the gable-shaped section (“gable” can be used as a synonym for P220116 PCT) used) widens toward the base structure, which can be understood figuratively as “triangular,” i.e., narrow at the top and wide at the bottom. Conversely, these considerations also apply to the negative gable-shaped section, which, however, does not stand away from the base structure but rather protrudes into it, essentially “eating out” material from it.
  • the term "step” also originates from the field of house construction and usually refers to a single part of a staircase used for ascending or descending.
  • the step essentially comprises two adjacent surfaces: a tread and a rising surface, which creates the difference in height.
  • the tread corresponds to the width of the step when viewed from above onto the top side of the joining part
  • the rising surface corresponds to the height of the step.
  • a stepped gable is created, also known as a stepped gable, stepped gable, or cat-step gable.
  • the number of steps on the left and right sides of the gable-shaped section can be identical, or there can even be mirror symmetry, or the number of steps on the left and right sides can differ, which means that mirror symmetry cannot be achieved.
  • one or more joining surfaces extend along the tread and/or riser. The joining surface(s) of the negative and positive gable sections face each other, i.e., are aligned.
  • a single, continuous joining surface can form along the steps, but there can also be several individual, non-connected joining surfaces. If, for example, the positive gable section penetrates the negative gable section to such an extent that direct contact occurs in some places, these "contact surfaces" are not considered part of the joining surface(s), since contact at that point does not create a joint into which filler can be poured.
  • the term "complementary" is to be strictly understood as "opposing but complementary properties of an object.”
  • the negative and the positive gable-shaped section are such opposing objects (recess vs. projection) which complement each other in that they can be inserted into each other and, together with the joint or the filler to be filled into the joint, form a complete or supplemented new object.
  • a suitable filler can be, for example, a binding agent such as an adhesive or mortar, but also, for example, sand.
  • the joint can be filled, for example, by attaching a barrier, for example in the form of a (e.g., P220116 PCT A wedge-shaped board, which is driven into the joint from the top side of the joining parts, for example, and reduces the joint size so that the joining parts are "wedged".

Abstract

La présente invention concerne un raccord en forme de pignon pour assembler une première partie de jonction (11) ayant une partie négative en forme de pignon et une deuxième partie de jonction (12) ayant une partie positive en forme de pignon. La partie négative en forme de pignon et la partie positive en forme de pignon comprennent chacune au moins un échelon (30) comportant une surface de jonction. Les parties en forme de pignon sont conçues pour être complémentaires de sorte que la partie positive puisse faire saillie au moins partiellement dans la partie négative, formant au moins un joint (20) entre les surfaces de jonction, ledit joint (20) au moins étant au moins partiellement rempli d'une charge. Pour un maintien suffisant, les surfaces de jonction comportent des irrégularités de l'ordre de grandeur de 1 μm à 10 mm et/ou, dans une vue en plan, la hauteur et la largeur dudit échelon (30) au moins sont à un angle α ≥ 90° l'une par rapport à l'autre. L'invention concerne en outre des pièces de jonction raccordables à un pignon et leur production, un procédé d'assemblage de pièces de jonction, ainsi qu'une utilisation d'un raccord en forme de pignon pour l'assemblage de pièces de jonction, en particulier constituées de dalles de béton FRC.
