Description
Anchor rail and method for producing an anchor rail
The present invention relates to an anchor rail for fixing fastening means, hav ing a first rail part and a second rail part, which are connected to one another, and on each of which anchor webs are formed, wherein a channel-shaped re ceptacle for a head section of a fastening means is formed between a first wall of the first rail part and a second wall of the second rail part, and an inwardly projecting web is provided on the first wall and an inwardly projecting web is provided on the second wall, and the inwardly projecting webs cover the chan nel-shaped receptacle at the edge, and a method for producing an anchor rail.
EP 1 764 448 A2 discloses an anchor rail in which anchor webs are formed on a first rail part, which is connected to a second C-shaped rail part in a bottom area. This connection point between the two rail parts forms a weak point that can fail when fastening means are inserted into the second rail part and high forces are applied.
In addition, anchor rails in which the anchor rail is made from two rail parts are known (DE 10 2008 029 838 Al, DE 10 2018 003 160 Al), wherein each rail part comprises anchor webs and forms a wall which surrounds a channel for re ceiving fastening means. A bent-over, inwardly projecting web is formed on each wall which can be engaged behind by a head section of a fastening means. This allows tensile forces through the fastening means to be introduced directly into the anchor webs via each rail section, resulting in high holding forces. Such anchor rails have generally proven themselves, but bending high strength steel sheets is problematic, especially if they are to be produced with somewhat greater thickness. In the area of the channel-shaped receptacle, an inwardly projecting web on a wall section is bent almost at right angles, which limits the strength and thickness of the steel sheet and thus also the maximum holding forces permitted by the anchor rail.
It is therefore the object of the present invention to provide an anchor rail and a method for manufacturing an anchor rail that can absorb particularly high hold ing forces and can be manufactured effectively.
In accordance with one aspect of the present invention there is provided an an chor rail for fixing fastening means including a first rail part and a second rail part, which are connected to one another and on each of which anchor webs are formed, wherein a channel-shaped receptacle for a head section of a faste ning means is formed between a first wall of the first rail part and a second wall of the second rail part and an inwardly projecting web is provided on the first wall and an inwardly projecting web is provided on the second wall, and the in wardly projecting webs overlap the channel-shaped receptacle on the edge side, wherein an outwardly projecting support web projects at least in sections on the first wall and/or the second wall opposite the inwardly projecting web.
In accordance with another aspect of the present invention there is provided a method for producing an anchor rail for fixing fastening means, including the following steps:
producing two blanks for a first and a second rail part with anchor webs from a steel sheet;
producing strip-shaped blanks from a steel sheet;
welding a first strip-shaped blank to a first wall of a first rail part;
welding a strip-shaped blank to a second wall of the second rail part, and
connecting the first rail part to the second rail part wherein a channel-shaped receptacle for a head section of a fastening means is formed between the first wall and second wall, wherein each strip-shaped blank forms an inwardly pro jecting web on the first and second walls, which covers the receptacle at the edge, and an outwardly projecting support web.
As a result, in embodiments, after the anchor rail has been cast in concrete or another casting material, the outwardly projecting support web can be used to stabilize the inwardly projecting web. When a tensile load is applied by a fas tening means, the inwardly projecting web is pivoted slightly in a direction away from the anchor rail, wherein deformation is limited by the outwardly projecting support web, which forms an abutment. The outwardly projecting support web is supported on the cast material and can thus counteract deformation at the in wardly projecting web. This also prevents deformation of the wall, which acts as a kind of bending bearing. The attachment of at least one support web thus in creases the strength of the anchor rail in this area, resulting in the provision of higher holding forces.
Preferably, a support web is provided on both the first and the second wall, in particular a continuous support web, which extends over substantially the same length as the inwardly projecting web. This allows support to be provided over the entire length of the anchor rail. Alternatively, several sections of support webs can be fixed to one wall each.
The first wall, the inwardly projecting web and the outwardly projecting support web are preferably designed T-shaped in cross-section, so that the first wall is aligned essentially at right angles to the inwardly projecting web and the sup port web. The same applies to the second wall, which is preferably also ar ranged at right angles to the inwardly projecting web and support web attached thereto.
For effective manufacturing, the support web can be welded to the first or sec ond wall, for example by a laser welding process. Preferably, the support web is integrally formed with the inwardly projecting web so that they can be fixed to the first or second wall with high accuracy. Tests have shown that a sufficiently stable connection between webs and the wall aligned at an angle to them can be produced by a welded connection, in particular by laser welding.
In a preferred design, the support web and the inwardly projecting web are made of a metal sheet, in particular a steel sheet, which is thicker than the first and second rail parts, which are preferably also made of a metal sheet, in par ticular a steel sheet. As a result, the inwardly projecting web, against which a head section of a fastening means rests, can be of particularly stable design. The inwardly projecting web is preferably at least 20% thicker, for example at least 1 mm thicker, than one of the two rail parts forming the walls.
Alternatively or in addition to the thickness design, the support web and the in wardly projecting web may be formed from a material of higher strength than the first and second rail parts. By using a high-strength steel sheet to produce a strip-shaped blank for the support web and the inwardly projecting web, the area subjected to forces by fastening means can be made more stable even with the same thickness as the rail part by selecting a suitable material.
The support web and the inwardly projecting web are preferably made from a flat steel sheet, in particular by a strip-shaped blank, wherein this blank is con nected to the first or second wall in a central region by a welded butt seam. The inwardly projecting web and the support web can project from the respective wall by, for example, 1 mm to 20 mm, in particular 3 mm to 12 mm. The thick ness of the strip-shaped blank for producing the two webs can be, for example, between 2 mm to 10 mm, in particular 3 mm to 8 mm.
Each rail part is preferably made of a bent steel sheet. The anchor webs are preferably aligned at an angle to the respective wall on the rail part. The first and second rail parts can be connected to each other by welded connecting webs, as disclosed for example in DE 10 2020 103 568. Optionally, the two rail parts can also be integrally formed with each other and manufactured from a single blank.
In a further design, the inwardly projecting webs each have a toothing in order to be able to fix the fastening means in the longitudinal direction of the anchor rail. To fix the fastening means in the longitudinal direction, a retaining plate with teeth at the edge can be provided, as disclosed in DE 10 2020 102 977.
Thus, in the method according to an embodiment of the invention, instead of bending two rail parts and then joining them, an additional component is pro duced by the strip-shaped blank, which is welded to a wall of a rail part. As a result, the loaded area of the anchor rail can be made particularly stable by se lecting the strip-shaped blank in accordance with the mechanical requirements. In addition, the outwardly projecting support web can limit deformation of the in wardly projecting web, since the support web is supported on the cast body in the cast state.
Preferably, the welding of the first and second strip-shaped blanks is performed by laser welding, in which the material in the contact area between the strip shaped blank and an end face of a wall of a rail part is melted without welding additions. This allows the inwardly projecting web to be positioned on the first or second rail part with a high degree of accuracy.
Preferably, a strip-shaped blank is welded to an end face of each of the first or second walls in a central region via a butt seam so that the strip-shaped blank protrudes from the respective wall on opposite sides.
The invention is explained in more detail below by means of an exemplary em bodiment with reference to the accompanying drawings, wherein:
Figs. 1A and 1B show two views of an anchor rail according to the inven tion;
Fig. 2 shows a sectional view through the anchor rail of Fig. 1, and
Fig. 3 shows a sectional view through the anchor rail of Fig. 1 with a fastening means.
An anchor rail 1 comprises two rail parts 2a and 2b which are made of a metal sheet, in particular a steel sheet. Integrally formed anchor webs 3 are provided on each rail part 2a and 2b, which have a widened foot section 4 and are later immersed in a cast body, in particular one of concrete.
A recess 5 is provided at least on one part of the anchor webs 3 in order to use the web-shaped material punched out on three sides at the recess 5 to produce a connecting web 6a or 6b. The connecting webs 6a and 6b are of stepped de sign at their facing end so that the two rail parts 2a and 2b can be fixed at a predefined distance. The connecting webs 6a and 6b are preferably welded to o gether as described in DE 10 2020 103 568.
As shown in particular in Fig. 2, there is a wall 8a on the first rail part 2a, and spaced from the first wall 8a a second wall 8b formed integrally with the second rail part 2b. A channel-shaped receptacle 13 for inserting a head section of a fastening means is formed between the two walls 8a and 8b. The channel shaped receptacle 13 is bounded by the connecting webs 6a and 6b, which are fixed to each other.
The anchor webs 3 are aligned at an angle to the wall 8a or 8b, preferably by an angle a, which can lie in a range between 50 and 300. A kink 9 is provided between the anchor bars 3 and the wall 8a or 8b.
An inwardly projecting web 10 is provided on opposite sides of the channel shaped receptacle 13. The two inwardly projecting webs 10 cover the edge of the channel-shaped receptacle 13 and leave a slot through which the fastening means with the head section can be inserted into the channel-shaped recepta cle 13. A toothing 11 is formed on the inwardly projecting webs 10 in order to be able to fix the fastening means in the longitudinal direction of the anchor rail 1.
The inwardly projecting webs 10 are not integrally formed with one of the rail parts 2a or 2b, but are made from a strip-shaped blank which also forms an outwardly projecting support web 12. This flat blank is preferably made of a steel sheet which is connected in a central region to an end face of the first wall 8a or the second wall 8b by a welded butt seam 14. The inwardly projecting web 10 and the support web 12 thus protrude from the respective wall 8a or 8b on opposite sides.
In Fig. 3, the anchor rail 1 is shown with a fastening means 20 in the form of a hammerhead screw. A head section 21 of the fastening means 20 has been in serted into the channel-shaped receptacle 13 and rotated so that the head sec tion 21 engages behind the two inwardly projecting webs 10. A threaded sec tion 22 protrudes from the head section 21 from the anchor rail 1, to which fur ther components can be attached.
In order to fix the anchor rail 1 precisely in a casting, in particular a concrete body, a retaining bracket 30 is provided, which has a projecting flange 31 on opposite sides in each case, which can be fixed to a formwork component by means of fastening means, for example nails. A bracket-shaped section 32 thereby embraces the channel-shaped receptacle 13, which is surrounded by the walls 8a and 8b and the connecting webs 6a and 6b. The retaining bracket 30 may be designed as described in DE 10 2019 124 308.
To manufacture the anchor rail 1, two blanks are made from a steel sheet, from which the first and second rail parts with the anchor webs are formed. In addi tion, strip-shaped blanks are produced from a steel sheet which later form the inner webs 10 and the support webs 12. The steel sheet for the strip-shaped blank can be thicker and/or of higher strength than the steel sheet for the rail parts. For example, the thickness of the strip-shaped blanks may be 20% greater than the thickness of the blanks made of the steel sheet for the rail parts. In particular, the thickness can be more than 0.5 mm, in particular more than 1 mm. Alternatively or additionally, a steel sheet can be selected for the strip-shaped blank which has a higher strength than the steel sheet for produc ing the rail parts.
After the blanks have been produced, a first blank is welded to a first wall 8a of the first rail part 2a and a second strip-shaped blank is welded to a second wall 8b of the second rail part 2b. The welding is preferably carried out using a laser welding process, in which the material on the wall 8a or 8b is melted in the area of the contact surface to the strip-shaped blank with or without welding addi tions. The strip-shaped blank is welded in a central area via a butt seam 14.
Temporally independent of this welding, the two rail parts 2a and 2b can be welded to each other via the connecting webs 6a and 6b, wherein preferably the rail parts 2a and 2b are manufactured individually with the welded-on blanks, since these can be manufactured identically. After the weld has been produced, the rail parts 2a and 2b can then be welded together via the connect ing webs 6a and 6b.
In the illustrated exemplary embodiment, the connecting webs 6a and 6b are made of material provided by making a recess 5 on the anchor webs 3. It is ob viously also possible to connect the rail parts 2a and 2b by connecting webs made from the blank for the rail parts 2a and 2b at a different position. In addi tion, separate connecting webs made of a different material can also be used to connect the two rail parts 2a and 2b. In a further alternative, the rail parts 2a and 2b can also be manufactured in one piece.
