Definitions

  • the invention relates to a force-transmitting wood connection according to the preamble of claim 1.
  • the invention has for its object to provide a force-transmitting wood connection, which reduces the workload for planning, construction and in particular for assembly at the construction site to a minimum.
  • a recess is made in the surface of a wooden body and a dowel body is fitted into this recess.
  • This dowel body has recessed, when inserted dowel body extendable to an end position, extending transversely to the dowel body, power transmission members, which in the same way as the known, the sheet metal screws tensile forces that are applied to the dowel body, to the wood.
  • tensile forces can be transmitted as high as the cross-section of the dowel body allows, since there is no design restriction for the length of the dowel body and thus also for the number of force transmission members.
  • the dowel bodies can be inserted and anchored already during cutting in the sawmill or in the factory producing glued wood binders, so that only connecting elements are to be used at the construction site. The workload at the construction site is thus reduced to a minimum.
  • the dowels according to the invention can be produced in different sizes, which are each designed for the transmission of a certain maximum force.
  • the design effort is therefore limited to the selection of anchors that have the appropriate strength.
  • the previously required individual construction of nodes is no longer necessary.
  • the force transmission members can be designed as fold-out teeth or barbs which, when a tensile force is exerted on the dowel body, automatically pivot into a position transverse to the latter and then remain in this position.
  • the dowel body is designed as a hollow body, the wall of which has transverse openings.
  • the force transmission elements are designed as pins which are fitted in the openings so that, when they are in the end position, they can be supported on them with the part remaining within the openings so that they can be supported by the pins and the openings Forces can be introduced into the wall of the hollow body.
  • the inner end of the pins is located within the cavity of the hollow body, while the front parts of the pins are received and guided in the openings are.
  • the outward-pointing ends of the pins at most protrude beyond the outer contour of the dowel body. so far that they do not interfere with its insertion into the recess in the wood.
  • the dowel created in this way is not only structurally simple, but also provides high power transmission, which does not change significantly even with aging, cracked wood, since the formation of a crack in the area of a pin hardly impairs its power transmission, especially since no tension state is required for the power transmission is because the pins are tension-free in their end position after they have drilled themselves into the wood.
  • the pins can be locked in their end position in order to ensure that the extended pins cannot fall back into their starting position when an alternating load occurs and a simultaneous vibration occurs.
  • the dowel body is preferably designed as a tube with a round cross section, the pins projecting radially from this cross section;
  • a dowel body when joining flat supports at the end face, which is formed from a tube with a flat profile, for example an elongated oval profile; in this case the pins are preferably arranged only on the ends or narrow sides of the dowel body.
  • the pins can have a square or rectangular profile, in which one side extends transversely to the direction of loading in order to transmit the highest possible load.
  • the local load on the wall of the dowel body is reduced in the region of an opening, so that this configuration also contributes to the increased load-bearing capacity of the dowel according to the invention.
  • the pins are arranged in at least one row, which extends parallel to the longitudinal axis of the dowel body. So it is possible to use the dowel according to the invention with a small edge distance to a wooden side surface so that no pins penetrate to the outside.
  • pins of adjacent rows are offset from one another in the longitudinal direction of the dowel body in order to avoid weak points in the wall of the dowel body.
  • the inner ends of the pins are each attached to a row together on a longitudinal web, which in turn forms an end stop when extending the pins and ensures that all pins after extending are each in their optimal end position.
  • the inner ends of the pins are welded to the longitudinal web, so that only one longitudinal web is to be inserted so deeply into the interior of the cavity in order to attach the pins that the pins each fall into the associated holes in a row.
  • the inner mouths are each connected to a series of openings through a longitudinal inner groove, which is designed to accommodate the respective longitudinal web.
  • the longitudinal webs are in turn supported on this inner groove and are therefore able to participate in the power transmission.
  • each of the longitudinal webs is in the end position with the dowel body welded so that the dowel is permanently attached to the associated wooden body.
  • an expander is provided for driving out the pins, which can be inserted into the cavity in order to guide the pins into their end position.
  • This expansion body can be an expandable, multi-part device, which can be removed from the cavity again after the pins have been moved into their end position.
  • the expansion body is designed as a pointed driving pin, which presses apart the respective pins or the longitudinal webs when driving in due to the bevel in the area of its tip.
  • This expansion body preferably remains in the interior of the dowel and in turn forms the lock, which prevents the individual pins from leaving their end position.
  • the dowel body has an internal thread on at least one of its end sections, into which a connecting and force introduction pin can be screwed.
  • the internal thread can be arranged in a region of the dowel body in which the above-mentioned pins are also present, which must then be designed such that they do not prevent the screwing in of a connecting pin in their end position.
  • an end section which in turn has the internal thread, is connected to the force transmission section of the dowel body which has the openings and thus also the pins.
  • the dowel according to the invention is screwed into a beam at the end, it only requires one end section.
  • the dowel according to the invention has two end sections, each with a thread, which run in opposite directions to each other.
  • the dowels in the case of beams which are adjacent to one another on the end face and are to be connected to one another in such a way that two opposing threaded sections meet each other.
  • a clamping threaded bolt arranged between these can then be screwed between the beams like the clamping bolt of a cable tensioner; after tightening this clamping bolt only the remaining gap has to be filled with wedges or the like.
  • the driving pin is provided at its end with an external thread which fits the internal thread; by means of a suitable design, such as a hexagon socket, the driving pin can thus be screwed into the interior of the hollow dowel body by the force-translating action of the thread to move the pins apart; if the driving pin is in place, the above force-transmitting pin is screwed into the internal thread behind it.
  • the driving pin and the force introduction pin are braced against each other, so that a permanent connection is created, which is not caused by external vibrations and similar effects that occur during the life of the wood connection can be solved.
  • the driving pin can also have a shaft section which, in the end position of the driving pin, protrudes from the end of the dowel body when the pins are extended. If the thread is to be secured, this can be achieved by puncturing, gluing or similar means.
  • the shaft section of the driving pin in turn forms the force introduction pin.
  • the end of the dowel body is flush with the wooden body carrying the recess; This has the advantage that the dowel, as already mentioned above, can be attached to the wooden body at the factory, with projecting parts of the dowel not hindering transportation.
  • the opening of the hollow dowel body can be closed by a plastic plug or the like, which may also be screwed into the dowel body.
  • the cross section of the inner body is chosen according to the cross section of the wooden body to be connected.
  • the dowel according to the invention is particularly suitable for forming a knot, but not, as in the beginning described, known nodes, the individual connecting bodies are in turn welded together, but according to the invention a pipe socket with a polygonal cross section is provided, the number of pages corresponding to the number of bars to be joined to form the node and the width of the front width of the respective bars. In each of these sides, holes are made at those points at which the force introduction pins or possibly also protruding dowel bodies protrude from the end faces of the beams. These pins or dowel bodies are welded to one another and to the polygon tube from the inside of the tube.
  • the manufacturing accuracy of the bores in the polygon pipe socket is subject to very little requirement, since any inaccuracies that are present are compensated for during welding.
  • the polygon pipe socket can thus be drilled in the workshop, so that at the construction site for the production of the knot only connecting pins may have to be screwed into the dowel body, the individual beams with the protruding parts of their dowels must be inserted into the polygon pipe socket and finally at the same Inside the welding work is required.
  • This welding work can largely be done from above in the relatively large, clear cross-section of the pipe socket, the walls of which protect the adjacent wood from scorching. Machining, especially of metal parts, on the construction site is not necessary.
  • the polygon pipe socket can be omitted, the protruding ends of the respective dowels being dimensioned such that they collide when the beams are joined and can be welded directly to one another.
  • the invention relates not only to the connection of two or more wooden bodies by means of dowels and to these dowels themselves, but also to a method for producing such a wood connection.
  • This method consists in the fact that the wooden bodies are clamped at the factory at least in the area in which the force transmission members of the dowel are arranged, and only then are the force transmission members extended with the clamping in place in order to prevent the wood from bursting apart.
  • glue binders in which several layers of wood are pressure-bonded to one another, the power transmission members are extended according to the invention when the pressure required for gluing is also exerted on the glue binders.
  • the driving pin while a clamping pressure is exerted on the respective wooden body, is moved hydraulically into the interior of the dowel body, either by the fact that the driving pin in turn serves as a hydraulic piston, or by interposing a hydraulic piston, the end of which acts on the driving pin.
  • the force transmission members it is also possible for the force transmission members to be extended by the pressure wave generated during thermal welding and then to be welded to the dowel body by the temperature which occurs at the same time.
  • the invention further relates to a method for producing a knot, in which a polygonal pipe socket, which is closed on both sides, is filled up by thermal welding after the protruding ends of the connecting dowels have been inserted.
  • This has the particular advantage not only of a particularly low-stress and good welded connection, but also in particular the advantage of low thermal stress on adjacent wooden parts, because despite the high temperature that occurs during welding, the total amount of heat to be applied for the welding process is very small compared to other welding processes. The tedious overhead welding is also avoided.
  • the thermal welding process can also be carried out by semi-skilled workers. It is thus possible to assemble and weld allergic elements such as knots without a single construction on the construction site in a very short time without additional adjustment work.
  • the invention thus makes a very important contribution to reducing the construction costs and shortening the construction time.
  • pins are preferably designed as hollow pins.
  • the strips are connected to a force transmission element, into which the forces can be introduced from the strips and which, in turn, like the dowel body described above, transmits these forces.
  • the advantage of this configuration lies not only in the fact that the relatively complex dowel body can be dispensed with, but also in the fact that, according to the respective outer shape of the hollow body provided with the recess and the size of the forces to be transmitted, the point at which the inventive pin-reinforced metal strips to be pressed radially into the recess wall can be selected.
  • the number of metal strips can also be matched to the forces to be transmitted. This results in the high flexibility that is particularly required for construction.
  • the strips inserted into the recess have a mutual spacing in the circumferential direction.
  • a support body is inserted, preferably pressed, into the recess which is now almost exposed again.
  • This support body can be a hardwood rod or a steel tube. It may even be possible to create an adhesive connection between the radially inner back of the strips and the support body used, by means of which additional forces can be transmitted.
  • a perforated support body to the metal strips by means of thermal welding.
  • the location at the mouth of the recess is the end of the M etalleisten connected to a ring which in turn forms the necessary force introduction element.
  • This ring can be welded to the metal strips, for example.
  • the metal strips preferably have a projection at their end on the side on which the pins protrude, and the ring is designed as an annular body with an internal circumferential groove, into which the projections of the individual metal strips engage.
  • this ring body is inserted in a corresponding manner in a mouth-side, enlarged section of the recess in such a way that it is flush with the outer surface of the wood.
  • the ring body is first inserted, then the metal strips are inserted and pressed in successively, the engagement between their projection and the inner groove of the ring body being produced simultaneously during the pressing-in.
  • the subsequently introduced support body extends to the area of the projections and thus prevents them from evading inwards.
  • the open outer end of the ring body is preferably provided with an internal thread into which a connecting bolt can be screwed in order, for example, to be welded to the pipe socket of a knot connection will.
