Definitions

  • the invention relates to a method for connecting at least two, in particular butt-jointed, beam-shaped wooden components, at least one of which is permanently installed in a building and in which at least one plate-shaped connecting lamella, in particular made of wood, extending over the joint area is attached to the two wooden components .
  • the force-transmitting beams which are usually permanently installed in the building, cannot and should not be completely replaced. Rather, only the damaged part of the beam should be removed and the beam should instead be extended with a new wooden component. The extension must take place in such a way that it can transmit shear, longitudinal and transverse forces again, especially since the support area of the beam is usually damaged.
  • the above-explained method is based on the idea of connecting the wooden components to be connected to one another at the intended installation location by means of a plurality of sandwich-like superimposed connecting lamellae with a stepped length, in such a way that the stack of lamellae engages in the two wooden components via a step. It is essential that the connecting lamellae are installed one after the other and that before each lamella is installed, a flat contact surface is produced on which the lamella to be installed can rest on its entire surface. In this way, a connection is created between the two wooden components, which can transmit forces to a high degree.
  • the thickness of the connecting lamella below is expediently reduced in step d) during the production of the flush, flat bottom of the enlarged depression.
  • the thickness of the one to be installed The lamella is chosen to be larger than the final thickness in the fully installed state, and the connecting lamella is flattened when the recess is widened.
  • the depressions are preferably milled, in particular using a router with a pin mill rotating at high speed.
  • a guide device which is held on the wooden components and which allows the router to be displaced in one plane is preferably attached to the wooden components which are fixed relative to one another. It goes without saying that the wooden components can be provided with a raw staircase before the connection slats are installed, which only has to be reworked subsequently when the connection slats are installed.
  • the connecting lamellae can be nailed or screwed to the bottom of the depression, but are expediently adhesively bonded to the bottom of the depression.
  • a climate tent can be placed at least over the connection area of the wooden components, in which the connection area can be tempered in accordance with the adhesive regulations and kept at a certain atmospheric humidity.
  • the depressions are expediently expanded symmetrically to the connecting lamella below them.
  • the width of the widening of the depression transversely to the joint area ie in the longitudinal direction of beam-shaped wooden components, is equal to or greater than along the joint area, that is to say transversely to the beam.
  • Such Dimensioned connecting lamellae overlap with surfaces of the wooden components in a sufficiently large area.
  • Connection lamella stacks are preferably installed on opposite sides of the two wooden components in order to be able to step off the cross section of the wooden components particularly frequently and also symmetrically.
  • the connecting lamella stacks arranged on opposite sides are expediently arranged transversely to the joint area, i.e. in the longitudinal direction of the beam-shaped wooden components, offset by about half the width of the extensions of the depressions.
  • the butt joints resulting in the longitudinal direction at the ends of the connecting slats are distributed evenly along the wooden components in such a way that there is at most only one butt joint in each cross-sectional area.
  • the connecting lamellae preferably consist of wood. It goes without saying that the connecting lamellae do not have to consist of the same type of wood from which the wooden components are made. Alternatively, wood types of higher strength or connecting lamellas made of non-wood materials can be used. In particular, it can be considered to use flexible connecting lamellae in order, for example, to achieve articulated nodes in truss constructions.
  • Fig. 1 shows a wooden beam 3 extended during the renovation of a building by a wooden beam 1, for example a roof truss or a wooden beam ceiling, which is firmly connected to the building, here anchored with its end in the masonry 5, and a load-bearing structural part of the building forms.
  • a wooden beam 1 for example a roof truss or a wooden beam ceiling, which is firmly connected to the building, here anchored with its end in the masonry 5, and a load-bearing structural part of the building forms.
  • stacks 9 each made up of a plurality of plate-shaped connecting lamellae 11, are glued into suitable recesses 13.
  • the length of each connecting lamella 11 is equal to the length of the recess 13 in which it is inserted.
  • the lengths of the connecting lamellae 11 are stepped within each stack 9 and increase from the inside of the beams 1, 3 to the outside.
  • the protrusions with which an outer connecting lamella 11 projects above the underlying inner connecting lamella in the longitudinal direction of the beams 1, 3 are symmetrical to the longitudinal center of the innermost connecting lamella 11.
  • all the protrusions are of equal size, the length of each protrusion transverse to the butt joint 7, ie in the longitudinal direction of the beams 1, 3 being equal to or greater than the width of the connecting slats 11 along the butt joint 7, ie transversely to the beams 1, 3 Overhangs thus have a square shape or a rectangular shape in the longitudinal direction of the beams 1, 3. As can be seen from Fig.
  • the two stacks 9 are offset in the longitudinal direction of the beams 1, 3 by half the length of the projections of the individual connecting lamellae 11 to prevent more than one end joint at the end of each connecting lamella 11 in the same cross-sectional plane of the beams 1, 3.
  • the connecting slats are made of wood and have fibers running essentially in the longitudinal direction of the beams 1, 3.
  • the beam 1 is first fixed in alignment with the beam 3, for example by temporarily nailed battens or the like (not shown in more detail) or, if appropriate, by removal after the renovation has been carried out Support structures fixed.
  • a guide, indicated at 15, for a milling device, for example a router or the like, not shown, is then attached to the fixed beams, with the aid of which flat surfaces can be milled in the connecting area of the beams 1, 3, which parallel across the butt joint 7 stretch into one of the beam surfaces into both beams 1, 3.
  • the recess 13 for the innermost and therefore the shortest connecting lamella 11 is milled symmetrically to the butt joint 7 in such a way that the recess has a flat, flush transition into the two beams 1, 3.
  • the innermost connecting lamella 11 is then glued in over the surface, the adhesive pressure being generated by a hydraulic press or by nail or screw connections.
  • the innermost recess extending to the outside of the beams 1, 3 is extended symmetrically in the longitudinal direction of the beams 1, 3 to the length of the closest connecting lamella, the recess again being given a flat bottom, which extends both over the extensions as well as the outer surface of the innermost connecting lamella extends flush.
  • connection lamella 11 which has already been glued in is expediently removed.
  • the connecting lamella which in turn is adapted to the length of the enlarged recess, is again glued in place and is also connected to the connecting lamella below.
  • This installation step sequence will repeated until the desired number of connecting lamellae is installed. If special climatic conditions have to be observed for the bonding, the bonding can take place in a climatic tent placed over the connection point of the beams 1, 3.
  • the method according to the invention is suitable not only for the extension of wooden beams, but also for the renovation of more complicated wooden structures, such as the junction of three wooden beams 17, 19, 21, as shown in FIG. 2.
  • the stack of the connecting lamellae need not be arranged on opposite sides in individual cases, and they can, as FIG. 2 shows for a stack 9a of essentially T-shaped connecting lamellae 11a, also extend through the entire wooden component, so that the bottom of the the first surface-to-glue connecting lamella is already formed by a base piece 23 which corresponds to the shape of the lamella but is also inserted.
  • the stack 9a is otherwise installed in the manner explained with reference to FIG. 1.
