Definitions
- the effect relates to a fastening element with a large-area washer and a tubular extension formed thereon for the passage and guidance of a screw.
- Such fasteners are usually used for fastening insulating materials on a solid surface, such. B. when attaching insulation panels to roofs. If materials have to be transported on a roof, it can happen that, for example, a worker steps on a washer or in the immediate vicinity or that a vehicle or tools drive over the washer. Such localized forces lead to the screw head penetrating through the applied seal or the washer penetrating the roofing membrane applied to the insulating material.
- Fasteners of the type described are z. B. in DE-A-35.39.752 (republished) and in AT-B-380.051 and GB-A-1.499.224 explained.
- a tubular extension is arranged on the relatively large-area washer, in which the screw is inserted.
- the head of the screw lies within this tubular extension and is arranged relatively far recessed relative to the top of the washer, so that the required screw length is significantly reduced.
- the thickness of the insulating materials to be fastened can therefore be bridged by the interaction of the length of the tubular extension and the length of the screw.
- the present invention has therefore set itself the task of creating a fastener of the type mentioned, which is very simple to manufacture and can be packed, transported and used in an economically optimal manner to the best possible extent.
- the washer and the tubular extension are designed as separately manufactured parts and that the tubular extension has a collar, projecting lugs, pins, knobs or the like at its end facing the washer and the section of the adjoining this end region tubular extension approximately corresponds to the passage cross-section of an opening in the washer and that the free inner diameter of the extension over its greatest length approximately corresponds to the outer diameter of the head of the screw to be inserted and the free end of the extension for producing a frictional holder between the extension and the inserted screw on the shaft - Or the outer thread diameter of the screw to be inserted is narrowed, so that the tubular extensions can be pre-stored with inserted screws.
- the separate production of the washer and the tubular extension in turn creates a type of joint between the washer and the screw connection Training part achieved so that a special sure-footedness is guaranteed.
- the washer can also tilt in such an embodiment with respect to the tubular extension, so that a one-sided load without. Problems can be intercepted.

- the fastening element consists of a screw 4 and a relatively large washer 5, which carries a tubular extension 6.
- a first exemplary embodiment of such a fastening element is to be explained in more detail with reference to FIGS. 2 to 7.
- the washer 5 and the tubular extension 6 are designed as separately manufactured parts, the tubular extension 6 having a collar 7 at its end facing the washer 5.
- projecting lugs, pins, knobs or the like can be provided instead of the collar 7 or in addition to the collar 7.
- the one to the federal government 7 subsequent section 8 of the tubular extension 6 is approximately adapted to the passage cross section of an opening 9 in the washer 5.
- the screw 4 has a head 10, a thread-free shaft section 11, a threaded section 12 and a self-drilling tip 13.
- the diameter of the shaft section 11 approximately corresponds to the outer diameter of the threaded section 12, the through opening 14 at the other free end of the tubular extension 6 also being matched to this diameter.
- the diameter of the screw head 10 corresponds approximately to the inner diameter of the cylinder section 15 in the tubular extension 6. It is therefore not only an optimal mounting between the tubular extension 6 and the screw 4 is given, but also a mutual centering, so that an exact setting during the screwing process is guaranteed is. With such an arrangement of a screw 4, an internal drive 16 is possible in a simple manner.
- the tubular extension 6 and the washer 5 Due to the separate production of the tubular extension 6 and the washer 5, e.g. the washer 5 made of metal and the tubular extension 6 made of plastic.
- the easiest way to implement the plastic is the tubular extension between screw and washer.
- the measures can also be provided which result in a simple pre-storage of the tubular extension 6 with the screw 4 and, in the case of a screw 4 with an internal drive 16, good guidance of the fastening element when setting by hand.
- this allows feeding via a loose pre-magazine and ultimately the fastening element can also be inserted in a magazine strip for an automatic screwing machine.
- the washers, if they are made of metal, can be fed into the known screwing machines without problems.
- this is convex.
- This not only brings about a desired stiffening of the washer, without ribbing of any kind being necessary. This has a very positive effect, especially when using sweat welding agents when welding the covering roofing sheets.
- the convex arching of the washer can be designed in such a way that it falls off towards the edge and is sorted there for a good pressure distribution and, moreover, the welding process with the roofing membrane is not impaired.
- both the washer 5 and the tubular extension 6 may be expedient to manufacture both the washer 5 and the tubular extension 6 from plastic.
- a further variant results from the separation of the individual parts, since the washer 5 and / or the rough-shaped extension 6 and / or the screw 4 can thereby be made of rustproof material. This is an essential factor for fastenings that are exposed to the weather or any moisture.
- Some or all of a screw can be made of stainless austenitic steel. It is also conceivable to produce a screw from two or more sections with different materials or different material structures and / or different hardening, the individual sections being assembled by welding, gluing or the like. Such a solution would also be possible for the tubular extension 6 if the fastening element is seen for special types of use.
- tubular extension 6 composed of two or more sections of different material, different material structure and / or different hardening by welding, gluing or the like.
- the end 17 of the tubular extension 6 protruding from the washer 5 when in use is conically tapered on the outside. This results in a very simple pressing into the flexible insulating material during screwing in. There is therefore practically no resistance to the tubular extension.
- the washer 5 shown in FIGS. 2 and 4 to 6 is bulged.
- the washer 5 has a central, conically or multiply graduated opening 9, the peripheral edge 18 of the washer 5 and the opening edge 19 of the mountable opening 9 lying approximately on one plane.
- the collar 7 formed on the extension 6 is approximately adapted in its cross-sectional shape to the cross-sectional shape of the recess 20 in the washer 5.
- a further embodiment of a screw 4 to be inserted is shown in FIG. 8. This screw has a circumferential collar 21 at a distance from the screw head 10, on which the lower free end of the tubular extension 6 can be supported. This provides additional security against further treading when the unit formed from extension 6 and washer 5 is loaded.
- FIGS. 9 and 10 A further embodiment of the fastening element is shown in FIGS. 9 and 10.
- a screw 4 is used here, in which the outside diameter of the threaded section 12 is larger than the outside diameter of the shaft section 11.
- the diameter of the free passage at the end region 17 of the extension 6 corresponds approximately to the outside diameter of the threaded section 12 of the screw 4 sufficient guidance and retention of the screw shaft 11 is achieved in the extension, a sleeve 22 can be placed on the screw shaft 11, the outer diameter of which in turn corresponds to the outer diameter of the threaded portion 12 and can therefore be fitted exactly into the free end 17 of the tubular extension 6. So that this sleeve 22 can be easily placed on the shaft section 11 of the screw 4, it has a continuous longitudinal slot 23, so that a lateral attachment of the sleeve 22 is possible.
- the extension 6 can be separated at its one free end at an acute angle to its longitudinal axis, so that a kind of cutting edge 24 is formed. This not only facilitates pressing in in the axial direction, but also leads to easy penetration into the underlying insulating material when the extension 6 is also rotated with the screw 4. From this Fig. 11 it can also be seen that de
- Extension 6 has at its end assigned to the washer 5 in pairs opposite projecting pins 25.
- These projecting pins 25 result in an excellent possibility of magazining or the proper feeding of the extensions or the extensions already pre-magazised with screws to a setting tool. 11, these pins 25 protrude radially from the collar 7 formed at the free end of the extension 6.
- these pins 25 are connected to the collar 7 against the other free end 17 of the extension 6 directed.
- these projecting pins 25 are rounded on the surface 26 directed against the free end 17 of the extension 6.
- the tubular extension 6 is to be made with any length, that is also with a relatively short axial extent.
- a washer is also laid directly on e.g. Wooden formwork is required, which includes occurs in domed buildings. This allows a washer with a large opening to be fixed with a normal countersunk head fastener.
- such constructions can primarily be used for fasteners designed for anchoring in thin sheet metal, even with a large external thread diameter, e.g. can be used for gas concrete. Such a fastener can then still be inserted through the washer.
- FIG. 20 shows an embodiment of a washer 5 as has been used up to now, such an embodiment of a washer 5 also being able to be used in the same way in the construction of a fastening element according to the invention.
- a washer 5 with the recess 20 drawn inward is of course only to be used if a correspondingly flexible material, e.g. Insulating material to be attached.
- a collar 7 is arranged at one end of the tubular extension 6, which is approximately square in plan view. With an appropriate design of the recess in the washer 5, a rotation security for the extension 6 could be achieved. In addition, the square formation of the federal government 7 in plan view results in an optimal guiding possibility when feeding the extensions 6 in one
- the collar 7 arranged at one end of the extension 6 is also laterally delimited with two flat surfaces 28, which in turn are used for guiding in a magazine channel.
- the lower limit 29 of the collar 7 is rounded, so that the tubular extension 6 can pivot in a simple manner about an axis lying in the plane of the washer. This provides an additional possibility of compensation between the washer 5 and the extension 6, in particular when the washer 5 is subjected to a lateral load.
- FIG. 15 An individual supply of tubular extensions 6 is shown schematically in FIG. 15, the extensions 6 also being able to be fitted with the corresponding screws.
- These extensions 6 are inserted from above in the direction of arrow 30 into a tubular section 31, the position of the laterally projecting pins 25 in the region of the collar 7 being insignificant during insertion.
- sloping guide surfaces 32 are provided, on which the protruding pins 25 impinge.
- the tubular extension 6 is thus immediately oriented, so that the protruding pins 25 engage in the guide slots 33 which laterally adjoin the guide surfaces 32.
- These guide slots 33 are then guided in a guide channel 34 to the place of use, that is, to below the screwing device.
- FIG. 16 shows how the individual tubular extensions 6 can be successively pre-magazineed and fed on an inclined guideway 35.
- the protruding pins 25 are supported on the guideways 35 seen on both sides, the lateral distance being ensured by the mutual abutment of the tubular extensions 6 themselves.
- the same possibility naturally also arises with relatively short tubular extensions 6, as is shown in FIG. 18.
- An optimal vertical alignment of the extensions 6 is of course given when in the Extensions 6 the screws are already inserted and thus the required weight causes vertical alignment.
- FIG. 19 shows a schematic structure of a setting device, in which a washer 5 can be fed in after each setting operation via an inclined chute 36.
- the tubular extensions 6, which are already fitted with the screws 4 can be individually fed through a channel 37 so that they come into the position of the screwing axis 38.
- the unit formed from screw 4 and extension 6 remains in this position until the screw nut engages in the drive of the screw head by means of corresponding spring-back brackets 39 which engage behind the collar 7 of the tubular extension 6.
- a pre-magazine feed is possible if a corresponding feed device is provided on the input side of the channel 37.
- FIGS. 21 to 23 A further embodiment of an extension 6 can be seen from FIGS. 21 to 23, this extension 6 being formed from a plurality of sleeves 39 to 42 which are pushed coaxially into one another and are mutually fixed. An even simpler version is available if the. Extension 6 is made as a multi-layer wound part from a sheet metal blank.
- the embodiment according to FIGS. 21 to 23 can thus be formed from individual sleeves 39 to 42 or just from several layers 39 to 42 of a flat sheet metal blank that has been wound up accordingly.
- the outermost sleeve 39 or the outer layer 39 has at one end at least two diametrically opposed, nose-shaped bulges 43, which practically correspond to the collar 7 according to the embodiment according to FIG. 2.
- the outermost sleeve 39 or the corresponding outermost layer has a tab, nose 44 or the like which is pressed inwards in the guide region for the screw head 20 when it is produced from a sheet metal blank. It is thus a security against the washer 5, together with the tubular extension 6, from being depressed
- a projecting nose 25 is formed, which in turn can be used as a support and guide on a corresponding guideway 35.
- a side boundaries 46 of this punched-out window 45 is then at the same time also secured against rotation for the tubular extension 6 in the guide section.
- FIGS. 24 and 25 A special embodiment of a tubular extension 6 is shown in FIGS. 24 and 25.
- the collar 7 is aligned at one end of the extension 6 at an acute angle to the longitudinal axis of the extension 6. The angle corresponds to the direction of inclination of a guideway 35 for the pre-magazine feeding of these extensions 6 together with the screws 4.
- a special design of the washer 5 is required in such an arrangement.
- the tubular extension 6 is also made from a sheet metal blank, which is formed into a tubular body after the stamping process.
- a compact tubular extension 6 is achieved by means of bent tabs 48. It is essential in such an embodiment that cutting edges 49 projecting laterally from the free end 17 of the tubular extension 6 in the radial direction are formed. As a result, when the tubular extension 6 rotates, an opening is made in the insulating material, that is to say practically a corresponding opening is drilled out. In this embodiment too, bulges 43 diametrically opposite one another are provided instead of a collar 7.
- brackets 27 and 28 are provided on the extension 6 in the manner of a wall plug projecting against the direction of insertion, resiliently pushable bracket 50. Through this projecting bracket 50, the tubular extension 6 can still be inserted through the opening in the washer 5, which bracket 50 then put on accordingly. These brackets relax in the soft insulation material again and provide rotation retention.
- an embodiment is also provided at the conical end 17 of the extension 6 that a clamping or braking effect is generated with certainty. This can also change the loose turning properties of a screw be improved.
- the brackets 50 projecting on the extension 6 are offset by 90 ° to the pins 25 arranged on the collar 7. From Fig. 28 it can be seen that these pins 25 can slide on a guideway 35 and that in such a case the projecting brackets 50 of the successive extensions 6 bring about the proper mutual spacing of the tubular extensions 6.
- the collar 7 in the region of the protruding pins 25 has flats 51 oriented transversely to these protruding pins 25.
- the flattenings cause, among other possibilities, proper lateral guidance in a magazine channel, so that it is not possible to rotate the extensions 6 during the feeding and thus malfunctions in the feeding can be eliminated.
- the collar 7 can have different cross-sectional shapes which, depending on the intended use, turn out to be positive.
- a plurality of tubular extensions 6, aligned parallel to one another can be connected to one another via separable or tear-off webs.
- a mutual connection of adjacent extensions 6 via the projecting brackets 50 according to FIG. 27. It is also possible to carry out a pre-magazine together with the screws, so that a much faster setting process is possible.
- FIG. 31 An embodiment according to FIG. 31 is also possible within the scope of the invention, in which the collar 7 is bulge-like at one end of the extension 6, so that it would also be possible, among other things, to insert this collar 7 into a correspondingly shaped opening on a washer 5 to snap into place.
- simple guidance is also ensured in the case of a magazine feed, since there are currently no large lateral surfaces in contact with corresponding guide walls.
- the collar 7 has a cuboidal outer contour at the upper end of the extension 6.
- the extension or extensions pre-stored with screws since the flat sides of the federal government can be placed against each other.
- laterally protruding pins 25 are provided, then of course stacking is only possible in one direction.
- This design of the extension in the form of a cylindrical tube with the subsequent parallelepipedal collar 7 makes it very easy to form a stack, whether any screws are either already inserted into the position of use or protrude on both sides for handling advantages. This enables magazine storage later without additional aids.
- a frictional connection between the screw or the screw head and the tubular extension 6 can take place.
- one or more ribs 60 running in the axial direction are provided on the opening wall within the extension 6. It is also conceivable that the free ends of these ribs enclose a cylindrical contour and thus rest at several circumferential locations of the screw shank of the screw head by appropriate angular displacement and thus create a centering and a frictional connection.
- the tubular section of the extension 6 is of conical design, that is to say that the cross section of the extension 6 is circular immediately after the collar 7, whereas the section 62 facing the free end is elliptical in cross section.
- the free end 17 of the extension 6 can then in turn pass over to a circular end cross section.
- a web 61 is additionally provided, at least on two opposite sides, so that over a relatively long distance, based on the length of the extension 6, the same dimension A for one another to be stacked extensions 6 is guaranteed.
- the approximately square outer contour of the collar 7 additionally ensures that the fastener is secured against rotation when this collar 7 engages, for example, in a square opening of the washer 5.
- fastening element according to the invention is used against masonry or against concrete, a pre-drilling of a hole is usually necessary, but due to the optimal magazines possibility of the fastening element according to the invention, a wall plug can already be placed on the free end of the screw and thus also pre-magazined.
- the pre-stored successive tubular extensions are expediently offset from one another in terms of height, so that the imaginary planes through the free ends of the extensions extend at an acute angle to the longitudinal axes of the extensions. There is therefore a proper feeding or slipping in correspondingly inclined guideways.
- the fastening element according to the invention can optimally solve a multitude of requirements for such fastening elements. Economical setting is possible to ensure the corrosion resistance of the fastening, longitudinal rotation protection is provided, retention of the roofing membrane and thus long-term safety when fastening insulation materials, particularly on a roof, is possible. For this purpose, a number of measures are necessary, which can be solved by the embodiments according to the invention.
- this tubular extension is to have a telescopic element, which has means for pre-storing that exceed one
- extension is provided on its outer circumference with projecting rioocn, grooves, grooves or tooth-like projections.
- the tooth-like projections can be sawtooth-shaped. Therefore, not only is the screw frictionally connected to the extension, but a frictional connection between the extension and the insulation or roofing membrane is also achieved.
- Pre-storage could also be carried out immediately with the metallic fasteners. Then, however, the telescope effect could no longer be used, which is advantageous for the large insulation thicknesses. It is therefore de time a one-off production of tubular extensions of any length is the most advantageous type of manufacture and also for packaging.
- a rod magazine possibly already filled with screws, can thereby be fed to a setting device. Such a rod then only needs to be singed in the setting device, so that, for example, 21 or even 40 fastening elements can be preloaded at once.
