    description
    The invention relates to a connection fitting for the Längs¬ connection between pile pieces which consist of wood.
    The primary application of the connection fitting is the lengthening of wooden posts which rise from the bottom of a body of water and typically carry a jetty or a pedestrian bridge.
    Wooden piles, which are anchored in the ground under a body of water and project vertically up to above the water level, become much more slowly rotten, especially at the longitudinal area at the level of the water level, than in the longitudinal area clearly below the water level. For reasons of expense, it is therefore customary to separate the upper part of such piles from the lower part and to replace it with a newer upper part.
    One method for this replacement is to remove the upper part of the pile just below the water level, drill holes in the face of the remaining pile stub, insert concrete iron into the holes, provide the pile stump with upwardly projecting formwork, and pour the mold with concrete. Although this repair method leads to well durable piles, but is verbo¬ten for environmental protection reasons in many places. In US 5,419, 538 A (1995) a connecting fitting for wood parts is proposed, which is also applicable to the extension of ver¬tikale wooden posts. In the mutually facing surfaces of the wooden parts an annular fitting is inserted and anchored with screws in the respective wooden part. Diekreisringförmigen fitting parts have an axial nut thread in which a threaded bolt is screwed, which thus connects the two annular fitting parts and thus the Holz¬teile. The disadvantage is that for producing or loosening the connection, a wood part as a whole must be rotated very often around the profit axis, and that the annular Be¬schlagteile must be made very thick-walled in the axial direction in order to transmit bending moments to a significant extent nondestructive. Due to this thick-walledness, it is necessary, for technical reasons, to insert the annular fitting parts into depressions in the wooden parts. The production of these recesses is again relatively expensive.
    No. 4,097,165 A (1978) proposes a fitting for the lengthening of wooden posts which have a circular cross-sectional area, with a respective annular or circular-shaped fitting part being anchored on both end faces by means of many screws, the circular-disk-shaped striking parts being the same Outer diameter have as the cross-sectional area of the wood pile pieces. The two kreisscheibenför¬migen fitting parts are interconnected by a central, axially on both sides of the circular disk-shaped fitting parts projecting threaded sleeve and / or connected on its lateral surface verlausfaefende tabs, which by screws with radially running threaded holes in the circular disk-shaped Beschlag¬teilen are anchored. Optionally, screws also extend radially from the lateral surface of the pile pieces through said threaded sleeve and thus anchor the threaded sleeve in an axial displacement relative to the pile pieces. Although the pile connection may be mechanically stable, it requires considerable effort and the optical impression is rather unfavorable due to the much visible metal straps and screw heads.
    In the documents US 594749 A and US 1699256 A are already 1897bzw. 1929 so-called "keyhole connections" for Befestigungsi¬gen a piece of furniture on a wall or the attachment of Bettrah¬menteilen shown with each other. With the word " keyhole bond " For the purposes of this document, we mean connections between two parts, one part of which is an undercut
    Recess whose opening surface as a classic keyhole also has a narrower and an adjoining broader cross-sectional area, and wherein the second part protrudes from a bolt with an end, opposite the subsequent bolus widened head in said Ver¬tiefung, the head is wider than the closer cross-sectional area of the opening area but narrower than the wider cross-sectional area of the opening area. The connection may be assembled by inserting the head of the bolt through the wider cross-sectional area of the opening surface into the recess and then displacing the entire bolt normally to its longitudinal direction such that the bolt passes through the narrower cross-sectional area of the opening surface of the recess.
    Based on this prior art, the object of the invention is to provide a connecting fitting for the longitudinal connection between wooden pile pieces, with which, above all, wooden piles which rise from the bottom of a body of water and typically carry a boat jetty or a pedestrian bridge, The improvement over the compounds discussed for this purpose should consist in that the compound produced with the connection fitting to be developed is both optically inconspicuous with sufficient mechanical strength , as well as producible with little installation effort.
    For solving the problem, construction methods are assumed in which the fitting has two disks, one disk in each case being fastened to such an end face of one of the two pile pieces, which faces the respective other pile piece when the connection is finished, the connection between the disk and the pile piece are respectively by means of screws which pass through recesses in the disc into the wood of the pile piece and there in threaded engagement, wherein the discs are interconnected.
    As an improvement according to the invention, it is proposed to form the connection between the two disks by at least three keyhole connections, all of which are arranged eccentrically with respect to the center of the disk, whereby the closing directions of the individual keyhole connections are not parallel to one another, but in the circumferential direction to one another Or concentric circular lines around the center of the disks.
    The inventive design of the connection fitting, the two pieces of piles, after they were each provided with a Schei¬be, very easy to assemble together, so they are axially guided against each other, that the individual Bolzender keyhole connections in the respective complementary recesses of the keyhole Connections protrude at the other Pffstückstück and then by the movable (upper) pile part around the center of said circular line or circles a very small piece is rotated - which locks all keyhole connections simultaneously.
    By the keyhole connections, by which the two discs are connected to each other, are eccentric with respect to the Scheibenmit¬, the compound is well resistant to bending and bend bending of the pile around normal to the pile direction extending bending axes even with relatively thin trained discs.Indem with thin slices the Auslangen and the connection between the panes need not protrude laterally beyond the edge of the pane, the connection is visually unobtrusive.
    The invention will be explained in more detail with reference to drawings to an advantageous embodiment.
    Fig. 1: shows a side view of an invention according to two
    Pile pieces mounted exemplary inventive fitting.
    FIG. 2: shows one of the two panes 1 of the exemplary inventive fitting of FIG. 1 in a frontal view with an angle of sight on that side of the pane 1 which, in the mounted state, rests directly against a pile part.
    The exemplary fitting according to the invention according to the drawings has two identical, substantially circular disks 1, which each have a whole series of openings or bores 3, 4, 5, 6, 7, 8, which extend from the upper side to the lower side Slice 1 pass through. The discs 1 typically consist of aluminum or stainless steel.
    A central bore 8 in the disc 1 helps to position the disc on the face of a pole piece 10 when the center is marked on it.
    Three holes 7, which are arranged in a narrow circle around the central bore 8 around, serve to fix the disc 1 at the end face of the associated peg 10 at least during assembly. For this purpose, with suitably placed on the front side of the piling piece 10 disc 1 through these Boh¬ ments through screws which have a threaded shank with selbst¬bohrender threaded tip screwed into the post 10 until they rest with her head on the disc 1 undsie press against the piling piece 10. Thus, after the disk 1 is prefixed to the pawl piece 10 " is in the same way as be¬ written further screws having a threaded shank with selbst¬bohrender threaded tip, through the holes 6, which are arranged along a larger circle around the central bore 8 around, screwed into the piling piece 10. As in
    2, the bores 6 preferably do not run normal to the plane of the disc 1, but slightly inclined out of the normal of the disc 1, wherein more preferably the axes of different bores $ are not parallel to one another. As inFig. 2 can be seen lying in the exemplary embodiment shown here, the axes of all holes 6 in each case in levels dienormal to the plane of the disc 1 and in which the axis of the disc 1 is located. (The axes of the bores 6 are the generatrix of a circularly symmetrical cone about the axis of the disc 1.) By not aligning the bores 6 normal to the plane of the disc 1, the screws passing through the bores 6 are not parallel to the grain of the wood of the pole piece 10 aligned, which compared to a pa¬rallelen alignment of the screws, the pull-out strength is significantly increased. By said screws are also not aligned parallel to each other (because of said non-parallel Ausrich¬tungen the holes 6), the pull-out of all Schrau¬ben together is further increased again.
    The disk 1 has in each case three cavities 2, whose cross-sectional area lying parallel to the plane of the disk 1 is a flat surface. (A "flat oval surface" in this sense is a rectangular surface in which two opposite straight lateral lines are replaced by a respective arched semicircular arc.)
    The opening area of a cavity 2 to that side of the disc 1hin, which faces that peg 10 to which the disc 1 is directly connected by screws, is equal to the cross-sectional area of the cavity 2, ie a flat oval surface.
    The opening surface of a cavity 2 2u that side of the disc 1hin, which is facing away from that peg 10 to which the disc 1 is directly connected by screws, is a " final high surface " 3, ie an elongated surface along which a partially circular partial surface 3.1 with a larger circular diameter and a partial surface 3.2, which is longitudinal sections of a flat oval surface with respect to the diameter of the partial surface 3.1 of small width, lie one behind the other. The diameter of the part-shaped part section 3.1 is equal to the width of the hollow space 2. The width of the part surface 3.2 is narrowed relative to the width of the hollow space 2, on the side of the pane 1 facing away from said pile element 10 over a partial area of the height of the pane 1 Wall 4 protrudes from the lateral boundary of the cavity 2 and covers part of the cross-sectional area of the cavity 2.
    The three cavities 2 of the disc 1 are arranged at the same angular distance from each other along a circular line which is slightly smaller than the circumferential line of the disc 1 and in turn koa¬xial with the bore 8 is arranged. The partial surfaces 3.1, 3.2 are always in the same sense of order along this circular line (to the right, for each surface 3, you always meet first the partial surface 3.1 and then the partial surface 3.2).
    On the same circular line, on which the Hohlräuroe 2 lie in the same grid spacing around the bore 8 as a center behind each other hintererei¬, are also three threaded holes 5 with mutually equal angular intervals one behind the other. For the usual method of attachment between two Pfahlstücken10, which is outlined in Fig. 1, a screw 15 is screwed into each threaded hole 5jeder of each disk 1 and that from the side of the respective disc ago, of the Pfahlstück 10, with which this disc. 1 directly ver¬bunden by screws, faces away. The screws 15 are in each case screwed in so far that the distance between the head of the screw 15 is approximately equal to the thickness of the wall 4.
    Then, the piles equipped with the discs with the discs 1 are pushed forward to each other, that the individual heads of the screws 15 by a respective face 3.1 of an opening 3 in a cavity 2 in each of those disc to which the individual screws 15 are not threaded by / protrude. The diameter of the head of a screw 15 is smaller than the diameter of the partial surface 3.1 of an opening 3, but larger than the width of the partial surface 3.2. The diameter of the bolt of the screw 15 is so small that the bolt can pass through the face 3.2.
    Finally, a pile piece 10 (the upper, loose pile piece) relative to the other pile piece 10 (the lower, in the bottom veran'kerten pile piece) about the axis of the central bores 8 in je¬nem direction of rotation is rotated so that at the individual openings 2der the moving Disc 1, the narrower surface portion 3.2 of the opening is shifted to 3dorthin where previously the part surface was 3.1. In this way, the heads of all screws 15 slide in each case into that region of an opening 2 at which the narrower surface part 3.2 of the associated opening is located.
    In the form of a fastening fitting sketched in FIGS. 1 and 2, the two disks 1 hold together by means of six keyhole connections, in each case an opening 3 and a screw 15 interacting with one another. In this case, three screws 15 each protrude from a threaded bore 5 on the lower disc 1 in each case an opening 3 on the upper disc 1 and vice versa protrude three screws 15 of a respective threaded hole 5an the upper disc 1 in each case an opening 3 on the lower pane 1.
    Due to the keyhole connections, the two disks 1 are positively locked to each other against translatory relative movements in all conceivable directions.
    Against rotational movement relative to each other about the axis of the discs 1, the two discs 1 are held in a direction initially only by friction. At the latest when 10 something is attached to the upper pole piece, which is also attached to other posts, - for example, a post which carries a bridge or a bridge and is itself carried by several piles - this rotational movement is positively locked.
    The fitting according to the invention allows an optional second attachment between two pile pieces. To this end, as described, a disc 1 is attached to a peg 10 (typically the lower peg piece anchored rigidly in the ground) by means of screws passing through the holes 6, 7 of the disc and threadedly engaged with the material of the peg piece 10. The second pile piece is provided in the axial direction with a grid of through holes, which are arranged to each other in the same distance grid as the threaded holes 5 zuei¬nander. In the threaded holes 5 threaded rods are screwed, which are longer than the through holes on the second Pfahlstück. The second piling piece is attached to the first pile piece such that the threaded rods extend through the through holes in the second pile piece. Threaded nuts are screwed on the free ends of the threaded rods and tightened to press the second pole piece to the first pole piece.
    This second type of attachment is particularly recommended for short second pieces of pegs and if the ends of the threaded rods visible on the free end face of this peg piece and the threaded nuts anchored thereto do not visually interfere. Of course, other parts, such as the base of a shield, a lamp, an anchoring ring for a rope or a railing, etc., can be anchored comfortably to the threaded rods.
    For the sake of clarity, for the connection described above in detail, there are two parts (disks 1), one part having an opening with a smaller and a larger cross-sectional surface area (sub-areas 3.2, 3.1) and the second part (disk 1). from a part projecting, comprising a bolt and a widened head (screw 15), the term " keyhole connection " is summarized in the following claims and in the following summary. used. The term "locking direction of the keyhole connection" is also used. This is the direction in which the narrower sub-area 3.2 follows the wider sub-area 3.1, and in which thus the bolt is to move to fix the connection. It is to be expressly understood that the term " keyhole connection " generally means connections that function as discussed, even though the shape of the opening surface should not be reminiscent of the shape of a keyhole.
