Definitions

  • the invention relates to an end cap for a profile rail according to the preamble of claim 1.
  • Such an end cap is formed with a connector for connecting the end cap to the profile rail and with at least one opening, through which a fastening pin for mounting the profile rail, in particular on a formwork, can be passed.
  • the invention further relates to a rail arrangement comprising a profile rail and such an end cap, according to claim 6, and a fastening arrangement comprising such a rail arrangement and a fastening pin, according to claim 7.
  • anchor rails rails For attaching attachments, such as curtain walls, concrete elements, designed as anchor rails rails are known. Such anchor rails are often fixed to the formwork of the concrete element, for example, nailed down, and then poured into the concrete.
  • an anchor channel may have an end cap. End caps for anchor channels, in particular with openings for fastening pins for fixing the anchor channels to a formwork, are known, for example, from DE2916005 C2, US2014250825 A1, DE1814195 U and GB687272 A.
  • the object of the invention is to provide an end cap for a rail, a rail assembly comprising a rail and such an end cap, and a fastening arrangement comprising such an end cap, a rail and a fixing pin, which at low cost, especially manufacturing cost, and high reliability a particularly enable easy, precise and reliable mounting of the rail on a formwork.
  • An end cap according to the invention is characterized in that the at least one opening of the end cap has a local cross-sectional constriction for prefixing the attachment pin in the opening.
  • a first basic idea of the invention can be seen in providing a device for prefixing the fastening pin, that is to say in particular the nail, in the opening during assembly.
  • This means for pre-fixing the fixing pin provisionally holds the fixing pin to the rail during installation, and the fixing pin is automatically moved together with the rail to its correct position for fixing the rail to the formwork.
  • this can in a particularly simple manner allow assembly by only a single fitter, preferably without further aids.
  • the device for prefixing the fastening pin is formed by a local, that is to say only in regions, cross-sectional constriction in the opening.
  • This cross-sectional constriction can rest on the fastening pin, in particular on its shaft, and thus secure the fastening pin against undesired loosening during the forces typically occurring during assembly, that is to say the cross-sectional constriction can pre-fix the fastening pin. At the same time caused by the cross-sectional constriction prefixing may be sufficiently loose to allow subsequent driving of the fixing pin in the formwork and associated movement of the fixing pin relative to the end cap. This can be ensured by means of a cross-sectional constriction in a particularly simple and reliable manner.
  • the end cap is preferably made of a plastic material.
  • the connector may be formed, for example, as a connector.
  • the connector may be a male connector, which is insertable for connecting the end cap with the rail in the rail, preferably in a rail body of the rail.
  • the connector may for example have lamellae.
  • the opening is in particular arranged so that the fastening pin can be passed through the opening for mounting the rail on a formwork, that is, the opening extends expediently perpendicular to the longitudinal extension of the rail, vertically to the longitudinal extent of the optional male connector and / or perpendicular to a plane which is spanned by a rail slot of the rail.
  • the fastening pin is used in particular for fixing the end cap and thus the profile rail to a formwork.
  • the attachment pin can be a nail, but also a screw.
  • the fixing pin suitably has a head and a shank, the head being expediently larger than the opening for holding the end cap.
  • the cross-sectional constriction is formed so that the cross-sectional constriction acts to pre-fix the fastening pin against the shank of the fastening pin.
  • the rail advantageously has a rail slot flanked rail slats on which hammer head elements, such as hammer head screws can be set.
  • the rail can be an anchor rail.
  • Such an anchor rail has at least one anchor, which protrudes on the rail body of the rail.
  • the cross-sectional constriction is formed by tongues. These tongues protrude into the cross section of the opening and thus form the cross-sectional constriction.
  • the tongues are integral with the end cap, which can further simplify manufacture, for example, in an injection molding process.
  • the tongues each have the shape of a circular sector.
  • the opening of the end cap may in particular be a passage opening. It is also possible to provide a membrane puncturable by the fastening pin which closes the opening partially or completely.
  • this membrane can be a flea skin which sets itself up during manufacture in an injection molding process.
  • the opening may be cylindrical.
  • the end cap preferably surrounds the opening in an annular manner.
  • the cross-sectional constriction is arranged at one end of the opening, in particular on an end of the opening facing away from the formwork.
  • the space created thereby in the opening can absorb a deformation of the tongues particularly well.
  • the manufacturing cost can be even further be reduced, especially in an injection molding process, since the demolding can be facilitated.
  • a further preferred embodiment of the invention is that it has a centering mark for centering the profile rail.
  • This centering mark is expediently arranged in the extension of the rail slot of the profile rail connected to the end cap.
  • the centering mark can further simplify the correct positioning of the profile rail with a particularly low production outlay.
  • the centering mark is a centering notch. Such a centering notch is particularly visible and very easy to manufacture and save material.
  • the end cap on a stiffening ribbing, whereby particularly good mechanical properties can be achieved with a particularly low material usage.
  • the invention also relates to the intended use of the end cap.
  • the invention thus relates to a rail arrangement comprising a rail and an inventive end cap, wherein the end cap is connected by means of its connector to the rail and wherein the end cap preferably closes the rail end.
  • the invention further relates to a fastening arrangement comprising a rail arrangement according to the invention and a fastening pin, which is arranged in the opening of the end cap and held there by the cross-sectional constriction.
  • the attachment pin is preferably a nail or a screw.
  • FIGS. 1 A first figure.
  • FIG. 5 a perspective cutaway view from below of an inventive device
  • FIG. 6 shows the rail arrangement of the fastening arrangement according to FIG. 5 in a perspective cutaway view from above.
  • the fastening arrangement has a profile rail 10, at least one end cap 30 and at least one fastening pin 60.
  • the rail 10 is provided for pouring into concrete and has a rail body 1 1.
  • the rail 10 is formed as an anchor rail and has as such a plurality of anchors 18, which are arranged on the rail body 1 1.
  • the rail body 1 1 is designed C-shaped and has on its upper side an elongated rail slot 13 through which access into the interior of the rail body 1 1 is possible.
  • the rail slot 13 is bounded by two opposite rail lips 14, on which a guided through the rail slot 13 hammer head screw can be fixed.
  • the armature 18 are connected in the illustrated embodiment on the rail slot 13 opposite rear side of the rail body 1 1 with rail body 1 1. In principle, however, another arrangement of the anchors 18, for example laterally on the rail body 1 1, conceivable.
  • the rail body 1 1 is bounded by two opposite end faces, between which the rail slot 13 extends. At least one of these end faces of the profile rail 10 is closed by an end cap 30.
  • the end cap 30 has a plug-in connector designed as a connector 32 which is inserted into the rail body 1 1.
  • the connector 32 here exemplified with rotating contact blades, but can also be omitted.
  • the end cap 30 further includes a mounting leg 33 for attaching the rail body 1 1 and thus the rail 10 on a formwork.
  • the fastening leg 33 has a contact surface 95 for the formwork, which extends at least approximately in the plane defined by the rail slot 13 and / or the rail lips 14.
  • the fastening pin 60 is designed with a shaft 62 and a cross-sectionally larger head than the shaft 62.
  • the fixing pin 60 is thread-free executed as a nail. But it can also be configured as a screw.
  • the fastening pin 60 is used for fastening, in particular pinning, the rail arrangement on the formwork.
  • the end cap 30 has in its mounting leg 33 an opening 40 which passes through the attachment leg 33 of the end cap 30 from back to front, which opens into the contact surface 95 for the formwork and / or which is provided for performing the shaft 62 of the fixing pin 60.
  • the opening 40 is formed smaller in cross section than the head 61 of the fixing pin 60 so that the head 61 can anchor the fixing pin 60 passed through the opening 40 to the end cap 30.
  • the end cap 30 also has four circular sector-shaped tongues 42 which project into the opening 40 at the rear end, that is to say at the end applied to the contact surface 95 for the formwork. These tongues 42 form a flexible local cross-sectional constriction 41 which can provisionally hold the stem 62 of the attachment pin 60 during assembly of the track assembly to the formwork.
