Definitions

  • the present invention relates to a two-piece air layer anchor for a two-shell masonry with an inner shell and an outer shell, which are connected by the two-piece air layer anchor.
  • Air-layer anchor for insertion into the inner shell and the outer shell of a two-shell masonry are for example from the DE 297 18 804 U1 and the DE 102 29 115 A1 known.
  • the DE 297 18 804 U1 describes an air layer anchor in which a sheet in the region of a central portion and an outer shell portion is bent inwardly at the side edges, while the inner shell portion has the entire width of the sheet metal piece. Punched tabs are bent out of the plane of the sheet to achieve anchoring in the mortar.
  • the DE 102 29 115 A1 describes an air layer anchor (referred to therein as a "connecting element") which is integrally formed from a piece of flat sheet and whose inner shell portion has at least approximately the same width as the outer shell portion.
  • the air-layer anchor is a piece of sheet folded flat inward in the outer shell portion, bent into a closed cylindrical shape in the middle portion, and partially folded inwardly in the inner shell portion and partially bent inwardly with bulges.
  • Both known from the prior art air layer anchor are made in one piece or in one piece from a sheet and have a substantially flat inner shell portion for insertion into the inner shell of the masonry and a substantially flat outer shell portion for insertion into the outer shell of the masonry.
  • the substantially flat end portions of the air layer anchors ensure sufficient load absorption in one direction only, in particular tension and pressure load absorption. Due to the design known from the prior art, one-piece, made of flat steel air layer anchor can absorb the horizontal forces insufficient. This can adversely affect the necessary non-positive connection between mortar and air layer anchor in the long run.
  • the protruding part of the air layer anchor is usually bent upwards or downwards in a vertical direction.
  • the insulation and inserting the air layer anchor in the outer shell of the air layer anchor must be bent back into its horizontal output arrangement, resulting in a weak point, possible breakage or breaking point at the bending point.
  • the air layer anchor should also be used in inner shells with a so-called Dünnbettfuge.
  • a masonry with Dünnbettfuge is sometimes referred to as "glued" because the mortar layer between the wall elements is extremely thin, typically from about 1.5 to 2 mm.
  • the inventive two-piece or two-part air layer anchor for a two-shell masonry with an inner shell and an outer shell comprises as first piece or part an inner shell portion for insertion into the inner shell and as a second separate or separable from the first piece or part of an outer shell portion for insertion into the outer shell of the masonry.
  • the inner shell portion and the outer shell portion are made as two separate or separate pieces or parts that can be releasably connected together to form the two-piece air layer anchor.
  • the inner shell portion is preferably formed as a stamped part, which is for example formed integrally from a piece of flat sheet or flat steel and / or punched.
  • the outer shell portion is preferably formed as a wire part, which may have a circular cross-section, wherein also differently shaped cross sections, such as elliptical or rectangular cross-sections are conceivable.
  • the diameter of the circular cross section is for example 2 to 6 mm, preferably 4 mm.
  • the preferably round shape the cross section of the outer shell portion allows a load bearing (tensile and compressive load) in all directions and thus also in the horizontal direction.
  • the inner shell portion has a length of 95 mm and the outer shell portion has a length of 125 mm, wherein the total length of the two-piece air layer anchor is achieved in particular by changing the length of the outer shell portion.
  • the total length of the air layer anchor is locally adapted to the conditions, such as the distance from the inner shell and outer shell, by changing the length of the outer shell portion.
  • the length of the outer shell section can be varied as desired or, e.g. by selecting an outer shell portion from a plurality of outer shell portions of different lengths, while a fixed or constant length can be used for the inner shell portion.
  • the inner shell portion may include an inner shell connecting portion and the outer shell portion having an outer shell connecting portion, via which the inner shell portion and the outer shell portion are releasably connectable to each other.
  • the inner shell portion and outer shell portion are separated from each other.
  • the inner shell connecting portion and the outer shell connecting portion may form-fit with each other at least in one direction, and thus connect the inner shell portion and the outer shell portion to the two-piece air layer anchor.
  • the inner shell connecting portion is formed at the end of the inner shell portion which is not inserted into the inner shell
  • the outer shell connecting portion is formed at the end of the outer shell portion which is not inserted into the outer shell.
  • the inner shell connection portion may include one or more members for being bonded to or receiving the outer shell connection portion.
  • the inner shell connecting portion may have a, preferably circular, recess for receiving the outer shell connecting portion. This is particularly advantageous when the outer shell portion is formed as a wire part with a circular cross-section. If the outer shell section and / or the outer shell connection section have a circular cross section, the outer shell connection section can be inserted into the preferably circular recess of the inner shell connection section and hung there, for example, to enter into a connection with the inner shell section.
  • the shape and / or the diameter of the recess and the shape and / or the diameter of the, preferably tubular, wire part are matched to one another, so that the outer circumference of the wire part can rest on the inner circumference of the recess.
  • the recess may be a bore or another, in particular circular, cut-out, which may have, for example, an edge hole reinforcement for stabilizing the recess and the inner shell connecting portion.
  • the inner shell connecting portion may include a guide for guiding and / or stabilizing at least a portion of the outer shell portion, such as the outer shell connecting portion.
  • the guide is preferably formed at the end of the inner shell portion which is not inserted into the inner shell, and is preferably formed by two or more projections or webs which are integrally formed from the sheet metal of the inner shell portion and bent up or down perpendicular to the inner shell portion can. If the outer shell section is designed, for example, as a wire part with a circular cross section, then the wire part can be guided and received through the guide or between the projections or webs.
  • the at least two perpendicular to the inner shell portion protrusions or webs serve to accommodate and / or stabilize the wire part, but at the same time ensure the desired freedom of movement, for example, to accommodate the Schränkung (opposite movement of masonry shells by thermal influences).
  • the stability of the air layer anchor can also be increased by the nature of the outer shell portion, which is preferably designed as a wire or a shaped as a round body wire part, since the formation of a wire or round body allows at least almost equal load absorption in all directions.
  • the distance between, for example, two webs or projections is preferably matched to the width of the wire part, such as the diameter of the wire part, so that the wire part can be passed through the webs or projections and at least almost rests against the inner sides of the webs or projections.
  • the outer shell connecting section of the outer shell section formed, for example, as a wire part is preferably first guided through the projections matched to the diameter of the wire part (that is, the distance between the projections preferably corresponds at least approximately to the diameter of the Wire part or the connecting portion of the wire part, so that the wire part can be guided by the projections) and then received by the preferably circular recess of the inner shell portion connecting portion or hooked into this, to ensure the connection between the outer shell portion and inner shell portion.
  • the inner shell portion for example, formed from a piece of flat sheet or flat steel inner portion, preferably along its longitudinal axis a plurality of punched, for example, two, three, four, five, six or more punched on.
  • the punched holes are circular in shape and have a diameter of 6 to 10 mm, for example 8 mm.
  • the preferably circular punch-outs can be arranged along the longitudinal axis of the inner shell portion such that the respective centers of the circular punch-outs are located on the longitudinal axis of the preferably flat inner shell portion and the punched-outs are spaced from each other.
  • the Ausstanzungsabites in which the punched on the inner shell portion are arranged can be used to be inserted into the joint, such as a Dünnbettfuge, the inner shell, said punched by the better anchoring in the mortar of the Dünnbettfuge and thus a better and more stable anchoring of the Inner shell section in the Dünnbettfuge is achieved.
  • the inner shell portion has a width of 14 to 18 mm, in particular 16 mm. If the inner shell section is formed by a flat piece of sheet metal, the thickness of the sheet piece is, for example, 0.3 mm to 0.7 mm, preferably 0.5 mm.
  • the inner shell portion may also have a counterpressure flap which, for example, may be partially punched out of the inner shell portion formed by a sheet and may be bent up or down perpendicular to the inner shell portion.
  • the counterpressure flap in the opposite direction of the guide, as the at least two projections or webs, bent.
  • the counterpressure flap is in particular formed between the inner shell connecting portion and the punched portion and serves to receive the pressure exerted by the outer shell portion connected to the inner shell portion.
  • the preferably formed as a wire part outer shell portion for example, in the recess of the inner shell portion mounted so pushes the end of the wire part, especially under load, against the back pressure flap. This occurring due to the preferably circular cross section of the wire part punctual Pressure load can be converted by the flat shape of the counter-pressure plate in a flat compressive load and thus reduce deterioration of the inner shell of the masonry.
  • the outer shell connecting portion is formed such that it can enter into communication with the inner shell connecting portion, in particular with the guide and the receptacle of the inner shell connecting portion for forming the two-piece air layer anchor.
  • the outer shell connecting portion which is preferably formed at the end of the outer shell portion which is not inserted into the outer shell, on the shape of the inner shell connecting portion adapted bend, preferably a Z-shaped bend, on.
  • the horizontal components of the Z-shaped bend may extend along or parallel to the inner shell portion and the vertical component of the Z-shaped bend may extend perpendicular to the inner shell portion through the recess of the inner shell connecting portion. to ensure a connection between the inner shell and outer shell section.
  • the preferably wire-shaped outer shell portion may have a wave-shaped end portion, the waves preferably being in the vertical direction, i.e., in the vertical direction. in the direction of the vertical component of the Z-shaped bend.
  • the waveform it is also possible to form the waveform into another, such as a horizontal direction. If the wave-shaped end section is inserted into a joint, such as a thick-bed joint, the outer shell, the wave shape ensures a more stable anchoring of the outer shell section in the mortar layer of the thick-bed joint and thus also a more stable anchoring of the air layer anchor in the outer shell.
  • the inner shell portion when pulling up the inner shell of a clam shell masonry only the inner shell portion can be introduced into a joint of the inner shell and thus hardly, but at least significantly less than a one-piece air layer anchor projecting from the inner shell.
  • the inner shell portion does not have to be bent in order to reduce the risk of injury, so that no additional weak point, possible breakage or predetermined breaking point is generated.
  • the risk of injury without the necessity of bending away of the inner shell portion is reduced in previous pulling up the inner shell.
  • the air layer anchor can be adapted more flexibly to the needs.
  • the more stable wire part in the case of a circular cross-section, can absorb loads in all directions equally well. With a flat sheet-like outer shell section, a load-bearing would only be reliable in one direction, as in the vertical direction, and not in all directions.
  • one-piece, flat, formed of sheet metal air layer anchor can not absorb the horizontal forces sufficient and thus loosens in the mortar joint.
  • An example of a wire-shaped outer shell section ensures a load bearing, such as the inclusion of a tensile and / or compressive load, in all directions.
  • the outer shell portion may also be made of a flat sheet for introduction into a thin-bed joint
  • the inner shell portion may be formed as a wire member having a circular cross-section for insertion into a thick-bed joint.
