Description

The present invention relates to a profile rail and fastening means for fastening the profile rail on a formwork for at least partially embedding the profile rail in concrete and a method therefor.

Known profile rails, which can also be called anchor rails, profile anchor rails or mounting rails for anchoring in concrete, are usually C-shaped along a longitudinal axis of the profile rail with a rail back, two lateral legs, each with angled wing sections, the wing sections each extending as far from one another that a rail slot with a rail slot width in between remains open. The rail slot is related to the fact that one or more screws can be inserted in it, in order to be able to screw other parts onto the profile rail. The screws can preferably be mounted anywhere along the rail slot and preferably transmit forces transversely to the longitudinal axis of the rail. A special embodiment has a toothing on the inside of the wing sections so that the toothing can also transmit forces parallel to the longitudinal axis of the profile rail. A plurality of anchors, such as, for example, profile anchors or round anchors, are preferably connected to the back of the rail, or these can be connected in order to bring about a better positive anchoring of the profile rail in the concrete when cast in concrete. The term "concrete" also stands for any other casting compound, such as cement or concrete or building material mixtures, which are suitable for pouring or embedding the profile rail.

In the back of the rail, a plurality of holes are or are preferably made along a center line, through which the profile rail can preferably be nailed onto the casing. Before the profile rail is poured into concrete, the profile rail on the side with the rail slot is temporarily connected to the formwork in such a way that the profile rail with the rail slot sits tightly on the formwork, which is flat, and is connected to it. The mounting of the profile rail on or on the formwork is generally done by nailing or screwing onto a common wooden or plastic formwork. The profile rail is connected to the formwork by pins or nails which are driven through the holes in the formwork, or by screws which are screwed or screwed through the holes in the formwork or screwed and countered. The holes have a hole diameter or cross section, that is matched to the pins, nails or screws. The arrangement of the anchors along the back of the rails often has to be carried out individually, with the rails, which are standardized rails, having to be subsequently changed and adapted individually in accordance with the requirements of the individual construction project.

Alternatively, in a widespread embodiment of the profile rail, holes are made at approximately regular intervals in the back of the rail, the diameter of which allows penetration of the nail shaft but not of the head. These nail holes must be made as part of the production process or in a separate operation in the back of the rail, e.g. by drilling or punching; this process is time-consuming and costly.

DE 10 2007 040 279 A1 discloses various possibilities of how the profiled rail can also be bound with wire to the casing, through which the two wire ends are guided, pulled and locked in front of the casing, in order to pull and hold the profiled rail against the casing.

After the concrete has hardened, the formwork side walls and the formwork, which is connected to the profile rail, are removed, so that the sides provided for further fastening are exposed in a concrete surface from inserts cast into concrete. The formwork can then be cleaned and reused elsewhere. A disadvantage here can now be nail ends or screw ends protruding from the profile rail, which usually have to be ground down laboriously and pose a risk of injury or have to be chipped off with the aid of a chisel. Only after such time-consuming work is the profile rail available for use with appropriate special screws (hammer or hook head).

DE 20 2015 003 443 U1 discloses a profile rail, in which in a profile rail interior, which is formed between the legs and the rail back, a respective holding element is connected to the profile rail, against which the casing is pulled and locked by means of a screw connection. This method eliminates the need to grind or bend the nail ends or screw ends, but it is more expensive in terms of material and installation.

DE 9 108 942 U1 discloses a profile rail formed in c-profiled cross-sectional shape with holes provided in the rail back through which holding nails can be hammered in and through to the respective formwork board on which the profile rail lies. In an opening gap opposite the holes, fill strips are one Closing the opening gap provided. After the profile rail has been cast in, in a subsequent step, after the formwork board has been removed, the protruding holding nails have to be turned over or pinched off, for example, the ends of the holding nails still being present and visible.

CH 379 734 A. discloses the profile rail with the holes and holding nails provided in the back of the rail, which are designed such that a holding nail head is screwed onto a respective holding nail mandrel via a thread. With the screwed-on holding nail head, the holding nail can first be hammered into the formwork board. After the profile rail has been poured in, the formwork board can be pulled off in a subsequent step and the protruding holding nails can simply be bent and unscrewed. The disadvantage here is that the thread in the holding nail is often damaged when the holding nail is driven into the formwork board, and the subsequent removal of the holding nail mandrel is thereby made even more difficult.

EP 1 486 629 A2 discloses a similar threaded holding nail as CH 379 734 A. with the same advantages and disadvantages.

Suitable special screws, which are inserted in the profile rail and passed through the rail slot, are selected based on planning and approval documents according to the size of the profile rail and its type of use (pull, transverse pull, etc.). A user generally identifies the profile rail using a marking or embossing on the inside of the rail. Out DE29903167 shows that an embossing can also be part of an anchor. Or the embossing can be built into the production process as a separate process. Both techniques are expensive. Alternatively, labels are applied, the weather resistance of which is often questioned by users.

Profile rails are required and produced in different lengths, generally between 100mm and 6m, depending on the application. DE 19907475 discloses a method in which anchors are passed through anchor holes in depressions in the back of a rail and are secured captively by material deformation. These anchor holes are generally made with a punch embossing tool together with the holes for the nails or screws and the respective countersinks. After inserting and fastening the anchors, corrosion protection can be applied. Out EP2388382 it is known that plugs in the holes for the nails or screws can be used to protect an unprotected surface in the hole area by sealing against corrosion. However, this does not solve the problem of lack of corrosion protection for the larger anchor holes in which an anchor is held. thats why It is usually common to apply corrosion protection only after all work that can damage the surface. The later setting of an additional anchor is generally not intended.

EP 1 486 629 A2 discloses an elongated screw with a nut as a connecting means between the profile rail and the casing, wherein the screw can be inserted through the corresponding hole in the back of the rail and screwed to the casing. The screw preferably has a predetermined breaking point, which shears off when the screw is turned against the nut with more than a predetermined torque when it is firmly cemented in place. This has the advantage that the casing can be removed from the profile rail in the cemented state, for example without a nail sticking out. However, the means used for this are expensive and require special screws, which can also damage the profile rail and its corrosion protection on the contact surfaces.

EP 2 199 476 A2 discloses a system of profile rail and connecting parts, wherein the connecting parts are designed as a nut and plug-like in such a way that they are preferably inserted from the inside through the respective hole of the profile rail and riveted therein, in order to screw the respective anchor to it from the other side, and so on to get an absolutely stable connection between them. In this way, the anchors can be connected to the profile rail shortly before cementing in, whereby volume is saved during the transport of the profile rails and the anchors can nevertheless be firmly and permanently connected to the profile rails.

DE 20 2015 003 443 U1 discloses a fastening technique of the mounting rail with the casing, the mounting rail being connected to the casing via fastening wedges, wherein after cementing in, either the casing is unscrewed from the fastening wedges or the fastening wedges can be pulled off or unscrewed from the mounting rail via a detachable connection. However, the effort of fastening the fastening wedges on both sides is high and the costs are not insignificant in terms of both special parts and work.

The current chaining of the manufacturing processes including the corrosion protection measures requires complex and expensive logistics.

The present invention is based on the object of eliminating the disadvantages of the prior art and of providing a profiled rail which is as simple and time-saving and cost-saving as possible with a formwork for a concrete casting by means of connecting means is connectable and from which the formwork can be detached again, overall with possibly protruding connecting means, and a corresponding method is to be provided for this.

The above object is achieved by a profile rail for attachment to a formwork for at least partial embedding in concrete according to the features of independent claim 1 and by a method for mounting the profile rail on the formwork according to the features of independent claim 13. Further advantageous embodiments of the invention are specified in the dependent claims.

According to the invention, a profile rail is provided for fastening on a formwork for at least partial embedding in concrete, wherein

• the profile rail is essentially C-shaped along a longitudinal axis of the profile rail by means of a rail back with two opposite legs projecting laterally at an angle therefrom, the legs having respective wing sections angled away from one another at their edges opposite the rail back, the respective wing section each having an outer edge, which is connected to the respective leg, and has an inner edge, so that the two mutually extending inner edges form a parallel rail slot and the two wing sections form a lowermost level in order to rest on the formwork with the lowest level,
  wherein a first plurality of holes with a respective hole cross section are formed in the back of the rail;
• a second plurality of plugs are inserted in the first plurality of holes,
• the respective plug along a central longitudinal axis of the plug Has cap section and an adjoining passage section, wherein the cap section has a first end face and a first outer cross section which is larger than the hole cross section, so that the cap section strikes and is retained when the passage section is inserted into the respective hole on the rail back, the Passage section a second end face, which lies opposite the first end face and has a second outer cross section, which can be carried out through the respective hole or can be pressed into it such that the cap section strikes the rail back;
• wherein the respective plug in the direction of the plug longitudinal axis for a respective elongated connecting element has a lead-through area which is designed to be penetrable manually by the connecting element and to guide the connecting element in the process;
• wherein the connecting element is designed as a nail or a screw with a head and a shaft with a length which is sufficient to connect the plug to the casing and to the profile rail therebetween.

The introduction of the plugs between the profile rail and the connecting element is particularly advantageous in the case of the present invention, since the plugs can be inserted at and removed from any locations prefabricated in the profile rail in order to provide a connection between the respective plugs via a respective connecting element the profile rail and the formwork. The connecting element has no direct contact with the profile rail and does not damage it or corrosion protection on the profile rail, which is preferably corrosion-protected overall with the prefabricated holes. The stopper is preferably a plastic stopper, which has the further advantages that, since it is preferably elastic, it can simply be inserted into the profile rail, preferably seals and is inexpensive. Compared to the connecting element, such as a nail, the stopper has a larger outer cross-section and accordingly, with the same compressive force, a smaller surface pressure towards the profile rail.

The prefabricated holes are preferably designed such that both a plug and an anchor can be inserted therein, so that the corresponding selection can be made directly on site at the construction site. This also saves a lot of time and costs or a complex and much more expensive planning in advance.

The stopper is preferably designed such that when it is seated in the profile rail and the connecting element for mounting the profile rail on the casing with the Formwork is connected, the plug is pulled through the connecting element up to a first tensile force through the rail slot to formwork, and the plug holds the connecting element. In addition, the stopper is preferably designed such that after the formwork has been removed later, the stopper releases the connecting element from a second pulling force in the direction from the stopper to the rail slot, allows it to slip or break out. The second tensile force is preferably greater than the first tensile force. The stopper is preferably sufficiently elastic at least in the lead-through area for the connecting element or has a predetermined breaking point, so that the connecting element can be pulled out of the hole in the profile rail through the rail slot from the second tensile force. The predetermined breaking point preferably breaks when a material of the plug can be pulled out in the area of the predetermined breaking point in order to form the predetermined breaking point by thinning the material. For example, the material that is to be pulled out can be connected to a tab which, when the plug is assembled, is arranged in the profile rail on the side of the passage area and is accessible from the rail slot.

Since an identifier or identification relevant for the profile rail is preferably applied to the stopper, preferably on the first end face and / or on the opposite second end face, this important identifier for the profile rail needs to be recognizable at any time, even when cast in concrete, not to be hammered or engraved into the profile rail itself with much greater effort. Wrapping or engraving the identifier in the profile rail itself is problematic with regard to a corrosion protection application if the corrosion protection would be partially milled or removed or if an anti-corrosion layer was subsequently applied and would make the identification difficult to read. A paint job can also be easily scraped off during construction; these problems do not exist with an imprint in the stopper.

Detailed description of exemplary embodiments

Fig. 1 shows a profile rail 2 of a preferred embodiment, which is intended for an at least partial embedding in concrete, as also mentioned at the beginning. Such a profile rail 2, which is also referred to as an anchor rail or mounting rail, is preferably provided with one or more anchors 3 or is already provided with the anchors 3 which are firmly connected to the profile rail 2 in order to provide a better hold of the profile rail 2 in the concrete cause. Fig. 2 and Fig. 3 show such rails 2 that with Anchors 3 are provided, which fix or "anchor" the respective profile rail 2 in a later state, in which the profile rail 2 is encapsulated with the concrete. As already mentioned at the beginning, the profiled rail 2 is first fastened in practice on a formwork 5 with connecting elements 4, in order then to be encapsulated with the concrete. Then the casing 5 is removed again, so that a rail slot of the profile rail 2 is visible.

The profiled rail 2 is essentially C-shaped along a longitudinal axis of the profiled rail by a rail back 21 with two opposite legs 20 protruding laterally at an angle therefrom, the legs 20 having respective wing sections 22 angled from one another at their edges opposite the rail back 21. The respective wing section 22 each has an outer edge 22a, which is connected to the respective leg 20, and an opposite, preferably parallel inner edge 22b, the respective wing section 22 being angled or bent away from the respective leg 20 connected thereto in such a way that the two face each other running inner edges 22b of the two wing sections 22 form a parallel rail slot 23. At the same time, the two wing sections 22 form a lowermost level, which lies opposite the rail back, the lowest level being predetermined in order to rest against the casing 5. Between the legs 20 and the rail back 21 and the wing sections 22, a profiled rail interior is formed, which should remain as free as possible from the concrete when the concrete is cast around the profiled rail 2, in order to be able to preferably insert at least one profiled rail screw 6 later in order to pass through the Profile rail screw 6, for example, to be able to connect a plate 8 to the profile rail 2, as in Fig. 8 is shown. Incidentally, is in Fig. 8 the connecting element 4 has already been pulled out or broken out after the profile rail 2 has been cast with the concrete, which is marked by the wide striations.

The rail back 21 has a first plurality of holes 24 with a respective hole cross section, into which a second plurality of plugs 1 are partially inserted according to the invention. The holes 24 are preferably arranged along a center line of the rail back 21. Alternatively, the holes 24 can also be arranged differently in the rail back 21. An additional arrangement of further identical holes 24 laterally in one or both legs 20 is also conceivable.

The respective plug 1 has a cap section 12 and a passage section 10 adjoining it along a central plug longitudinal axis, which are integrally connected to one another. 9-11 show embodiments of the plug 1. The cap section 12 has a first end face 12a with a first outer cross section that is larger than the hole cross section, so that the cap section 12 strikes and is retained on the rail back 21 when the passage section 10 is inserted into the respective hole 24. The cap section 12 is preferably designed such that at least its outer edge section running around the plug longitudinal axis cannot be pulled through the hole 24 even with the application of force. The passage section 10 has a second end face 10a, which lies opposite the first end face 12a and has a second outer cross section, which can be carried out through the respective hole 24 or can be pressed into it upon insertion until the cap section 12 strikes the rail back 21. The plug 1 has a lead-through area 13 in the direction of the plug longitudinal axis, through which a respective elongated connecting element 4 can be manually passed or pushed or screwed through. The lead-through area 13 is designed to guide the connecting element 4 in the direction of the plug longitudinal axis. The lead-through area 13 is preferably arranged centrally along the longitudinal axis of the plug. The connecting element 4 is preferably a nail or a screw or a pin and has a head and a shaft. The head of the connecting element 4 is at least so large and the bushing area 13 is so small that the head is retained by the plug 1 when the profile rail 2 is mounted or fastened on the casing 5, preferably experiences a stop and does not slip through the bushing area 13 . The shaft of the connecting element 4 has a length that is sufficient to be able to be connected to the casing 5. In other words, when using a nail or a screw as the connecting element 4, the nail or the screw must preferably extend into or through the casing 5 in order to be able to produce a sufficiently firm connection. Of course, it is also conceivable to use a plug nut through the casing, which means that the screw would not have to extend all the way to the casing 5, and the like. It is also conceivable that the plug 1 is preferably formed with two or more lead-through areas 13, through which a connecting element 4 can then preferably be driven toward the casing 5. In this way, the hold between the stopper 1 and the casing 5 can be increased. The respective lead-through area 13 in the plug 1 can be designed, for example, as a hole or as a blind hole with a penetrable cover wall or as a area with a cylindrical cavity along a lead-through axis for the connecting element 4. The hollow area can also be formed with a softer or thin-walled material. The lead-through area 13 can also be formed by thinning the material in the cap section 12 or in the passage section 10. When assembling respective connecting elements 4 through the stopper 1, which are introduced into the profile rail 2, guided, screwed or pushed and connected to the formwork, so that the profile rail 2 lies firmly on the formwork 5 and is held. The connecting elements 4 are preferably driven through the respective plug 1 to the formwork until a first tensile force acts on the respective plug 1 towards the formwork 5 along the longitudinal axis of the plug. As a result, the profile rail 2 is connected between the stopper 1 and the casing 5 at the respective point of the connecting element 4 up to the first tensile force with the casing 5.

Preferably, the respective connecting element 4 can then be pulled through the respective plug 1 or through the hole 24 from a second tensile force on its shaft in the direction from the plug to the rail slot 23, which is preferably higher than the first tensile force. The first tensile force preferably acts along the longitudinal axis of the plug from the cap section 12 to the rail slot 23. For clarity, the first tensile force of the shaft of the connecting element 4 acts on the stopper 1 in the direction of the casing 5, after the mounting of the profile rail 2 on the casing 5.

The respective plug 1 preferably has a predetermined breaking point 14 around the longitudinal plug axis, which is formed between an inner section 19a with the lead-through area 13 and an outer section 19b which remains outside the inner section 19a around the longitudinal plug axis. In 9, 10 and 11 Preferred embodiments of the predetermined breaking points 14 are shown in dashed lines. The inner section 19a has a cross section that is smaller than the hole cross section in order to be able to be pulled through the hole 24 together with the connecting element 4 if the predetermined breaking point 14 is broken. Preferably, the predetermined breaking point 14 breaks from the second tensile force of the connecting element 4 in the direction from the plug 1 to the rail slot 23. The predetermined breaking point 14 is preferably formed by an annular material wall thinning around the longitudinal axis of the plug. The predetermined breaking point 14 is preferably designed to hold the plug 1 in the direction of the casing 5 up to the first tensile force of the connecting element 4 and not to tear. For the sake of clarity, the meaning of the direction "towards the casing" means: from the plug 1 to the rail slot 23. In this case, a pivoting force or a pivoting moment can also favor breaking of the predetermined breaking point, so that the second tensile force can also preferably be smaller than the first tensile force. As a result, the profile rail 2 is pulled against the casing by the respective connecting element 4 and the stopper at the location of the respective connecting element 4 with up to the first tensile force. The predetermined breaking point 14 is preferably formed, starting from the second tensile force of the connecting element 4 To tear plug 1 in the direction of the rail slot 23 in order to be able to pull the respective connecting element 4 out of the plug with the second tensile force.

The annular material wall thinning is preferably formed by a material which can be pulled out of an area of the predetermined breaking point 14 and which is connected to a pull tab 15. The pull tab 15 is arranged in the assembled state of the plug 1 in the profile rail 2, preferably on the side of the passage area 10 and accessible from the rail slot 23. The pull tab 15 is exemplary in the Figures 4 , 5 and 9-12 shown.

The respective plug 1 in the lead-through area 13 is preferably designed to be so elastic that when the profile rail 2 is mounted on the casing 5, the connecting element 4 is held with the head up to the first tensile force in the lead-through area 13 of the plug 1, around the profile rail 2 in place to hold the connecting element 4 up to the first tensile force on the casing 5.
