    专利说明:

    [0001] The present invention relates to a fixing system and a process for fixing a complementary piece with a seat pin on a seat object.
    [0002] Fixing systems are used to fix a complementary part to a laying object by means of a pin. The complementary part is, for example, a grid plate, an electrical fixture or a spacer, and the object of settlement is, for example, a metal plate, especially a steel plate, or a concrete wall or a concrete ceiling. The seating pin has a clamping segment and a load application segment. The clamping segment is executed as a point and is inserted into the laying object with the aid of a laying device. In this case, the tip on the fixing segment of the seat pin deforms the material of the seat object and thus the fixing segment is fixed with a lock due to the force on the seat object. In the load application segment of the seat pin, the complementary part can be fixed, for example, by means of a thread. After insertion of the laying pin in the laying object, it is exposed, in the case of humid environmental conditions, to water, water vapor or moisture. This can cause corrosion of the seat pin. In the case of a carbon steel seating pin, the seating pin may also be weakened by hydrogen. This can cause a failure of the seating pin, so that the complementary part comes loose from the seating object.
    [0003] From document DE 1 475 052, a process is known for fixing an object, for example, a plate, on a carrier part, where a seat pin is thrown through a fixing element that in direction axial is relatively rigid, and the object to be fixed, into the carrier part.
    [0004] DE 10 2008 043 A1 shows a threaded pin with a fixing segment, a load application segment where a thread is arranged, and a head. The load application segment has a pin-shaped core area that is made entirely with the clamping segment and the head, the core area, the clamping segment and the head consisting of a material, and on the radially external side, a screw anchor that holds the thread of a plastic is fixed in the area of the core. In this, the fastening segment is provided with a plastic sealing element in the form of a circular disc.
    [0005] The task of the present invention is to provide a fixing system and a process for fixing a complementary part with a seating pin to a seating object, where corrosion on the seating pin can avoided in a lasting way.
    [0006] This task is solved with a fixing system for fixing a complementary piece to a seating object by means of a seating pin, comprising the seating pin that has a first end and a second end, with a clamping segment and a load application segment, a sealing element preferably in the form of a ring or bushing, with an opening to seal the seat pin inserted in a seat object, and the seat pin The complementary part is preferably placed inside the opening, for example, a grid plate, an electric fastener or a spacer, for fixing in the load application segment of the laying pin, the extension being axial length of the sealing element before placing the seating pin is at least 5%, 10%, 20%, 30% or 50% of the axial extension of the seating pin, so that in an inserted state of the seating pin the The seal is supported on a first end on the laying object, and on a second end, on the complementary part and / or the laying pin.
    [0007] Due to the axial extension of the sealing element, in the inserted state of the laying pin, the sealing element rests both on the laying object as well as on the complementary part and / or on the laying pin. The seating pin, after being placed on the seating object (carrier part), is exposed to the weather in the environment, for example, water or moisture. Due to this axial extension of the sealing element, the sealing element seals this partial axial segment against the environment, so that the seating pin is not exposed to moisture in the environment. In this way, corrosion or weakening due to hydrogen in the seating pin can be avoided. Advantageously, the seating pin can withstand large loads in a long-lasting manner, and the seating pin can also be made of a material that is subject to corrosion, where, however, around the seal with the no corrosion occurs. In this way, costs in the production of the laying pin can also be avoided. The second end of the sealing element can also be a second segment or area of the sealing element, independently of one end of the sealing element opposite the first end.
    [0008] In particular, the axial extension of the sealing element is carried out in the sense that, in an inserted state of the laying pin, the sealing element rests on a first end on the laying object and, in a second end, on the complementary part and / or the laying pin.
    [0009] In another embodiment, the inner diameter of the gluing element is greater than the maximum diameter of the seating pin, so that with the sealing element a partial axial segment of the seating pin in a state engaged between the seating object and the second end, especially the complementary part, is completely surrounded by the sealing element. The inner diameter of the sealing element, especially the maximum inner diameter of the sealing element, is greater than the maximum diameter of the seating pin. In this way, the sealing element can completely enclose the seating pin in the axial partial segment, and due to the sealing, that is, the support of the sealing element both on the seating object and also on the the complementary part and / or the laying pin, the partial segment of the laying pin is completely sealed against the environment.
    [00010] In a complementary design, the maximum diameter of the seating pin is only taken into account in a partial axial segment of the seating pin, where the sealing element is arranged.
    [00011] Preferably, the sealing element consists at least partially, in particular completely, of an elastic material, for example, an elastomer or plastic.
    [00012] In a complementary variation, the seating pin has a diameter between 0.5 mm and 15 mm, preferably between 0.5 mm and 10 mm, especially between 2 mm and 5 mm.
    [00013] Appropriately, the seat pin has a point on the first end and / or the seat pin has a device in the load application segment for fixing the complementary part, for example, a thread, a bayonet type lock. or a latch, especially of plastic and / or metal. At a first end with the tip, the seating pin is driven into or inserted into the seating object in the direction of driving.
    [00014] In another embodiment, the sealing element is arranged and / or fixed on the seat pin. The sealing element is already attached to the seating pin during the placement of the seating pin, and then the complementary part is fixed to the seating pin with the sealing element.
    [00015] In particular, the fixing system comprises the complementary part, and the sealing element is arranged and / or fixed on the complementary part. During the placement of the seat pin, the sealing element is not fixed to the seat pin, but only with the attachment of the complementary part to the seating pin, and the complementary part is or will be arranged or fixed the element the sealing system is equipped with the sealing element.
    [00016] In another embodiment the seating pin consists, at least partially, in particular completely, of metal, for example, steel, carbon steel, stainless steel, copper or aluminum. Appropriately, the seating pin consists of plastic, especially glass-fiber reinforced plastic.
    [00017] Process according to the present invention for fixing a complementary part with a laying pin on a laying object, especially with a fixing system described in the present patent application, with the steps: Placing the pin of laying on the laying object, for example, a concrete wall or a metal plate, joining the complementary piece with the laying pin, where the complementary piece is fixed on a load application segment of the laying pin sealing pin sealing with a sealing element, preferably in the form of a ring or bushing, with an opening, and within the opening the seating pin is arranged, and in this, the sealing element, in particular, is contacted with the laying object at a first end of the sealing element, the sealing element, especially at a second end of the sealing element, being additionally contacted with the complementary part and / or the seating pin, and thus the seating pin is sealed between the complementary part and the seating object, especially completely, against the environment. With this, the sealing element rests both on the complementary part and also on the laying object, so that in this way, especially because of the geometry of the sealing element, the sealing pin on the axial partial segment between the complementary part and the seating object is completely encircled and sealed by the sealing element. Preferably, the seating pin is also sealed by the seating object and / or the complementary part.
    [00018] Appropriately, a part for fixing the complementary part, for example, a cap nut, is also considered as a complementary part.
    [00019] In a complementary variation, the sealing element receives a pre-elastic tension between the complementary part and the laying object after the laying pin is seated.
    [00020] In another variation, the sealing element is and / or will be fixed on the seating pin and / or on the complementary part, before the placement of the seating pin.
    [00021] In another embodiment, after placing the seating pin, the sealing element completely involves a partial axial segment of the seating pin between the complementary part and the seating object.
    [00022] The complementary part is fixed to the laying pin especially fluid and dust proof, so that due to the sealing between the sealing element and the complementary part, and between the sealing element and the laying object , the seating pin is and / or will be completely sealed against the environment.
    [00023] In another embodiment, the shape of the sealing element is changed during the placement of the laying pin, in particular, the sealing element is elastically deformed.
    [00024] Appropriately, the seating pin is completely surrounded by the sealing element in a partial axial segment.
    [00025] In the following, examples of implementation of the present invention are described in detail with reference to the attached drawings. They show:

    [00033] Figure 8 shows the fixing system according to figure 7, after placing the seat pin on the seat object and when fixing the complementary part on the seat pin.
    [00034] Figure 9 shows the fixing system according to figure 7, after placing the seat pin on the seat object and after fixing the complementary part on the seat pin.
    [00035] Figure 10 shows a longitudinal section of the fixing system in a fourth example of execution, before placing the seat pin on the seat object.
    [00036] Figure 11 shows the fixing system according to figure 10, after placing the seat pin on the seat object and during the fixing of the complementary piece on the seat pin, and
    [00037] Figure 12 shows the fixing system according to figure 10, after placing the seat pin on the seat object and after fixing the complementary piece on the seat pin.
    [00038] Figure 1 to Figure 3 show a first example of execution of a fixing system 1. The fixing system 1 comprises a seat pin 2, a sealing element 10 and, preferably, a complementary part 14 With the help of the laying pin 2 the complementary piece 14 can be fixed on a laying object 17, for example, a concrete wall 18 or a metal plate 19. The laying object 17 is therefore the carrier part . The seating pin 2 has a first end 3 and a second end 4. A placement of the seating pin 2 with a placement device not shown occurs parallel to a longitudinal axis 20 of the seating pin 2 in the direction of placement accordingly. with the direction of the arrow in figure 1, that is, it is inserted or driven into the center of the seating object parallel to the longitudinal axis 20 of the seating pin 2. A lower securing segment 5 of the seating pin 2 is tapered or executed as point 7, and the complementary part 14 can be fixed in a load application segment 6. In this, the load application segment 6 has a device 8 for fixing the complementary part 14, that is, a thread 9. The load application segment 6 therefore has an external thread and in a hole of the complementary part 14 an internal thread is formed that can be screwed into the external thread of the load application segment 6, according to with the illustration in figure 2.
    [00039] Even before the installation pin 2 is placed, the sealing element 10 in the form of an elastic plastic bushing is fixed on the seating pin 2. The sealing element 10 has a first end 11 and a second end 12 and within an opening 13 of the sealing element 10, both the securing segment 5 and the load application segment 6 of the seat pin 2 are arranged or supported by it (figure 1). After the placement pin 2 is placed on the seating object 17 (figure 2), the clamping segment 5 is fixed on the seating object 17, essentially with a lock due to the force and preferably also with a lock due to the shape . In this way, the first end 11 of the sealing element 10 completely surrounds a partial axial segment of the seat pin 2 where the sealing element 10 rests. When screwing the complementary piece 14 into the load application segment 6 of the seating pin 2, the complementary piece 14 rests on the second end 12 of the sealing element 10, so that the elastic sealing element 10 rests on both the complementary piece 14 and also on the seating object 17, and presents between the complementary piece 14 and the laying object 17 a pre-elastic tension. In this, the complementary piece 14 surrounds the fluid-proof seating pin 2 and due to the sealing of the axial partial segment of the seating pin 2 between the complementary piece 14 and the seating object 17, the seating pin - ment 2 is sealed against the fluid-proof and dust-proof environment, according to the illustration in figure 3. Thus, with advantage, no damage caused by corrosion or embrittlement by hydrogen due to water and moisture in the environment. In the first example of execution, the sealing element 10 is attached to the seating pin 2, so that it is a sealing element of the seating pin 10.
    [00040] Figures 4 to 6 show a second example of execution of the fixing system 1. In the following, only the differences of the first example of execution according to figures 1 to 3 will be described in essence. The complementary part 14 has a hole and inside this hole the sealing element 10 is disposed after placing the pin 2. In this, the complementary part 14 is fixed in the load application segment 6 with the external thread by means of a piece 15 to fix the complementary part 14, precisely a cap nut 16, according to the illustration in figure 6. In this, part 15 is also considered complementary part 14, and in the illustration in figure 6, in analogy to the first example of execution, the element of seal 10 is under pre-elastic tension in axial direction between part 15, that is, the cap nut 16, and the seating object 17. As a result, also in the second execution example, the seating pin 2 is sealed against fluid-proof environment and dustproof. The sealing element 10 is attached to the seat pin 2 in the second design example as well, so that in the second design example it is also a seat pin sealing element 10.
    [00041] Figures 7 to 9 show a third example of execution of the fixation system 1. In the following, the differences with the first example of execution will be described. The sealing element 10 is not fixed on the seat pin 2, but on the complementary piece 14. Therefore, the sealing element 10 is a sealing element of the complementary piece 10. When screwing the complementary piece 14 on which the sealing element 10, the sealing element 10 is already in contact with the complementary piece 14, so that the complementary piece 14 is already sealed in relation to the sealing element 10. When screwing the complementary piece 14 in the direction of placing downwards, the sealing element 10 comes to rest and comes into contact with the seating object 17, and in the continuation of the screwing of the complementary piece 14 on the thread in the load application segment 6, the sealing element 10 receives a pre-elastic tension between the complementary piece 14 and the seating object 17. In this way, the seating pin 2 is sealed with an advantage against the fluid-proof and dust-proof environment, as the sealing element 10 completely surrounds the pin of seating 2 on a partial axial segment of the seating pin 2, and the sealing element 10 is fluid-proof on the complementary part 14, and fluid-proof on the seating object 17.
    [00042] Figures 10 to 12 show a fourth example of execution of the fixation system 1, The following will describe in essence only the differences of the third example of execution according to figures 7 to 9. As in the third example of In execution, the sealing element 10 is attached to the complementary part 14 and not to the pin 2, so that it is a sealing element of the complementary part 10. In this way, the shape of the sealing element 10 is distinguished of the third example of execution of the fixing system 1. The sealing element 10, between the first end 11 and the second end 12, in a partial segment, in the cross section is partially formed as an S-shaped hose, and a pre-elastic tensioning of the sealing element after placing the pin 2 according to the illustration in figure 12, is essentially obtained due to a deformation of that partial S-shaped segment of the sealing element 10.
    [00043] Seen in its entirety, the fastening system 1 according to the present invention has essential advantages. With the sealing element 10 of an elastic material, the seating pin 2 can be completely sealed against the environment in a seated state, so that in this way, corrosion or hydrogen embrittlement in the seating pin 2 can be avoided. , also in a humid environment.
