Definitions
- the invention relates to wooden components and a system for your connection according to the preamble of claim 1.
- the physical properties of the wood must be taken into account in the construction of wooden structures.
- the bulk density of wood is between 0.1 g / cm 3 (balsa wood) and 1.2 g / cm 3 (pock wood).
- the elastic modulus, the strength and the hardness increase with increasing bulk density, while the thermal insulation capacity decreases somewhat.
- the highest strength values occur in the fiber direction.
- the beam-shaped wooden building elements are lined up side by side without further precautions. There are therefore no gaps between the individual wooden building elements that could accommodate the lateral dilation. Seamlessly joined wooden building ducks are described, for example, by the patents CH 680 600 (publication date September 30, 1992), CH 650 826 (publication date August 15, 1985) and CH 516 713 (publication date January 31, 1972). Furthermore, it is known to fasten bar-shaped wooden structural elements to one another with tongue and groove connections. The use of tongue and groove joints in beam-shaped wooden structural elements is proposed, for example, by the patents EP 0 214 088 (publication date March 11, 1987), CH 680 600 and CH 650 826.
- the object of the invention is to provide bar-shaped wooden building elements and a system for their connection, which can absorb the lateral dilation of the individual wooden building elements and at the same time prevent the formation of steps between the wooden building elements.
- the connection system is intended to enable the wooden structural elements to be assembled quickly and without problems.
- the proposed wooden structural elements are preferably designed as box-shaped, elongated hollow bodies. They are referred to below as hollow beams. These hollow beams consist of a basic plank, a top plank and two side walls. They are joined together using the proposed connection system to form a flat structure, for example a floor or a wall.
- the connection system comprises a large number of long and short, dowel-like connection elements. These connecting dowels are divided into a cylindrical head and a cylindrical shaft, the head having a larger diameter than the shaft.
- the head is the same for both types of dowels. Its length is slightly larger than the wall thickness of the hollow beams. In the center of its free end face, a threaded insert with an internal thread is inserted into the head.
- the two types of dowel differ in the length of their shank.
- the shaft of the short dowel is about the same length as the dowel head.
- the shaft of the long dowel has a length which is slightly more than a bar wall thickness smaller than the bar width. Furthermore, a threaded rod piece with an external thread is inserted into the shaft of the long dowel from its free end face.
- the hollow beams are provided on two opposite walls at regular intervals with continuous, cylindrical bores.
- the holes in one wall are aligned in pairs with the holes in the other wall.
- the diameter of the bores in one wall corresponds to the diameter of the dowel shafts.
- the bores of the other wall have the same diameter as the dowel heads.
- the hollow beams are now joined together in such a way that a wall with thin bores lies next to a wall with thick bores, and that the bores of two adjacent beams are aligned in pairs.
- the dowels When assembled, the dowels run through the two adjacent walls of two adjacent hollow beams. Each dowel is inserted with its shaft into a thin hole in one beam wall and with its head in a thick hole in the other beam wall. If a long dowel is installed, the threaded rod section on its shaft is screwed into the threaded insert on the head of the previous dowel.
- connecting rods can be used instead of dowels.
- the diameter of all the bores in the two side walls of the hollow beams of a prefabricated component corresponds to the outside diameter of the connecting rods.
- the connecting rods are inserted into the holes in the hollow beam side walls. They run across all hollow beams of a prefabricated building element. Several transverse connecting rods are provided for each prefabricated component.
- the hollow beams are produced with the aid of a commercially available hydraulic wood glue binder press with swivel arms and vertical holding posts.
- the base plank, the top plank and the side walls of a hollow beam are held in their mutually correct position by a large number of cardboard frames before the pressing process.

- Fig. 5 different steps of the manufacturing process of the hollow beams
- Fig. 6 is a perspective view of a cardboard frame
- FIG. 7 shows a cross section through a large-area prefabricated component made up of a multiplicity of hollow beams and connecting rods.
- the proposed connection system ensures that when a flat construction of hollow beams 1 is formed, there are sufficiently large distances between them that allow free lateral dilation of the hollow beams 1.
- the spaces between the hollow beams 1 have the function of Buffer spaces in which the hollow beams 1 can expand. They are dimensioned in such a way that even with the greatest possible dilatation of the individual hollow beams 1 in the lateral direction, there is no change in the dimensions of the entire planar structure.
- the proposed connection system is primarily intended for wooden structural elements in the form of hollow beams 1 (cf. FIGS. 1 a to 1 c and 4), but it can also be used for solid wood beams (not shown).
- the solid wood beams must be provided with cross holes at regular intervals, which can accommodate the dowels 2, 3 (not shown).
- Solid wood beams are preferably only stabilized with long dowels 2.
- the diameter of the transverse bores corresponds to the diameter of a dowel head 4 in one longitudinal half of a solid wood beam and to the diameter of a dowel shaft 5 in the other longitudinal half.
- the drawings show the use of the proposed connection system for a ceiling which is composed of hollow beams 1 (cf. FIGS. 1 a to 1 c and 4).
- the direction of the proposed hollow beams 1 depends on the load to which they are exposed.
- the type of wood from which the hollow beams 1 are made also plays a role.
- the hollow beams 1 have a width of 190 mm and a height of 160 mm.
- Each hollow beam 1 is composed of four wooden boards 8, 9, which run in pairs parallel or at right angles to each other.
- the two boards 9, which form the underside and the top of a hollow beam 1, have a width of 190 mm. In the following, they are referred to as base plank 19 or cover plank 20.
- the two boards 8, which form the two side walls 7 of the hollow beam 1, are just half as wide. In order to produce narrow boards 8 from the wide boards 9, they only have to be halved in the longitudinal direction. This makes it easier the production of the hollow beams 1 essential.
- the thickness of the boards 8, 9 in the exemplary embodiment is approximately 33 mm.
- the two wide boards 9 lie with a large surface on two end faces of the narrow boards 8. The large outside of each narrow board 8 is flush with one end of each of the two wide boards 9.
- the boards 8, 9 are fastened to one another with glue connections.
- the wide board 9 on the underside is provided with a longitudinal groove 11 on each of its two faces.
- the side walls 7 of a hollow beam 1 are provided with continuous, cylindrical bores 12, 13 at regular intervals.
- the distance between two bores 12, 13 is 100 cm in the exemplary embodiment.
- the bores 12, 13 are e.g. attached halfway up the side walls 7. They can also be alternately offset in height so that the wood is not split. Furthermore, they run at right angles to the side wall outer surface.
- One of the two side walls 7 of a hollow beam 1 has thin bores 13, the other thick bores 12.
- the diameter of the thin bores 13 measures 25 mm in the exemplary embodiment. It corresponds to the diameter of the dowel shafts 5.
- the diameter of the thick bores 12 is approximately 200% of the diameter of the thin bores 13. It corresponds to the diameter of the dowel heads 4.
- the swelling properties of the type of wood from which the hollow beams 1 are made must be taken into account. If the maximum lateral swelling is 2% (2 cm per 1 m), then with a beam width of 19 cm the space between two hollow beams must be 14 to 5 mm so that the entire dilatation can be absorbed. With a bar width of 15 cm, the maximum lateral dilation is approximately 3 mm. Generally speaking, the dilation grows approximately linearly with the bar width.
- the total length of a long dowel 2 in the embodiment is 194 mm to 195 mm and is thus 4 to 5 mm larger than the beam width.
- the head 4 of a dowel 2, 3 is 45 mm long in the exemplary embodiment.
- the length of a dowel head 4 is consequently somewhat greater than the thickness of the beam walls 7.
- the dowel head 4 On its free end face, the dowel head 4 is provided with a cylindrical longitudinal bore 14 which runs along the central longitudinal Axis 6 of the dowel 2 runs (see. Fig. 2b and 2c). In the exemplary embodiment, this longitudinal bore 14 is 40 mm long.
- the front section of the longitudinal bore 14 has a larger diameter than the rear section. It receives a threaded insert 16 with an internal thread.
- This thread insert can be hexagonal or octagonal or round.
- the diameter of the front section measures 15 mm.
- the width of the threaded insert 16 corresponds to this diameter.
- the rear section of the longitudinal bore 14 has a diameter of 12 mm.
- the threaded insert 16 is fastened in the longitudinal bore 14 with adhesive.
- this longitudinal bore 15 is also 40 mm long and has a diameter of 12 mm. It receives one half of a threaded rod section 17 (see FIGS. 2a and 2b). The diameter of this threaded rod section 17 is 12 mm, its length is approximately 80 mm. The threaded rod section 17 can be screwed into the threaded insert 16 of a dowel head 4.
- a short dowel 3 is 95 mm long in the exemplary embodiment.
- the head 4 is of the same design as in the long dowel 2 (cf. FIGS. 3a to c).
- the dowels 2, 3 are preferably made of wood, plastic or metal.
- Figure la shows the cross section through two hollow beams 1, which are stabilized exclusively with long dowels 2.
- the two hollow beams 1 are arranged side by side at the same height. That side wall 7 of the first hollow beam 1 on the left in FIG. 1, which has thin bores 13, lies directly next to that side wall 7 of the second hollow beam 1, which is provided with thick bores 12.
- the long dowels 2 run transversely through the two side walls 7 of the first and second hollow beam 1 lying next to one another.
- Each dowel 2 is with its shaft 5 in a thin bore 13 in the side wall 7 of the first hollow beam 1 and with its head 4 in one thick bore 12 of the side wall 7 of the second hollow beam 1 inserted.
- the shaft 5 of a dowel 2 runs across the interior of the first hollow beam 1.
- Each dowel head 4 is in contact with the end face adjacent to the shaft 5 on the outside of the side wall 7 of the first hollow beam 1 facing it, since its diameter is larger than the diameter of the thin bore 13 in this side wall 7 Head 4 of each dowel 2 of the first hollow beam 1, the threaded rod 17 is screwed onto the shaft 5 of a dowel 2 of the second hollow beam 1.
- the threaded rod section 17 on each dowel 2 of the first hollow beam 1 is also screwed into the threaded insert 16 on the head 4 of a further dowel 2 each.
- This dowel head 4 is inserted into the thick bore 12 of the first hollow beam 1.
- long dowels 2 are also inserted into this hollow beam 1 from the side wall 7 with the thin bores 13 and screwed onto the dowels 2 of the first hollow beam 1. This continues until the ceiling reaches its full width.
- a conventional electric hand drill can be used to screw in the long dowels 2.
- a special insert is fastened in the drill chuck of the drilling machine, the outer section of which can be screwed into the threaded insert 16 on the dowel heads 4 (not shown).
- FIG. 1c shows the cross section through two hollow beams 1, which are stabilized exclusively with short dowels 3.
- the two hollow beams 1 are arranged side by side at the same height. That side wall 7 of the first hollow beam 1 on the left in FIG. 1c, which has thin bores 13, lies directly next to that side wall 7 of the second hollow beam 1, which is provided with thick bores 12.
- a large number of short dowels 3 extend transversely through these two adjacent side walls 7 of the two adjacent hollow beams 1.
- Their shank 5 is inserted into a thin bore 13 in the side wall 7 of the first hollow beam 1. It protrudes on the inside of this side wall 7.
- the head 4 of each short dowel 3 is inserted into the thick bore 13 in the side wall 7 of the second hollow beam 1 and also protrudes on the inside of this side wall 7.
- short dowels 3 are inserted into a first hollow beam 1 from the side wall 7 with the thin bores 13.
- a second hollow beam 1 is then attached to this side wall 7 in such a way that its side wall 7 with the thick bores 12 faces the first hollow beam 1.
- short dowels 3 are also inserted into this hollow beam 1 from the side wall 7 with the thin bores 12. This continues until the ceiling reaches its full width.
- the short dowels 3 only limit the displacement of the hollow beams 1 against each other. You cannot maintain the distances between the individual hollow beams 1 if they are not used in combination with long dowels 2. However, they have the advantage over the long dowels 3 that their price is lower.
- long dowels 2 and short dowels 3 are combined with one another.
- two short dowels 3 can follow each long dowel 2.
- any other combinations are conceivable. Which combination is most suitable in a particular case can be determined with the aid of structural calculations.
- FIG. 1b shows a cross section through two hollow beams 1, which are stabilized with a combination of long dowels 2 and short dowels 3.
- the hollow beams 1 and Dowels 2, 3 are arranged in the same way as in the case where only short dowels 3 are used (cf. FIG. 1c).
- the dowels 2, 3 thus run transversely through the side walls 7 of two adjacent hollow beams 1 lying next to one another.
- the threaded rod 17 on the shaft 5 of each long dowel 3 is in each case in the threaded insert 16 on the head 4 of one lying against this long dowel 3 long or short dowels 2, 3 screwed in.
- Combinations of long and short dowels 2, 3 prevent the hollow beams 1 from moving against one another. At the same time, the distances between the individual hollow beams 1 are also maintained.
- the costs for the dowels 2, 3 are also lower than when using exclusively long dowels 2.
- connecting rods 25 can be used instead of the dowels 2, 3.
- the width of the prefabricated building elements 26 is determined by the structural requirements of the building to be constructed, by the respective transport options and the width of the hollow beams 1 used.
- any number of hollow beams 1 can be lined up laterally. This means that the optimum width for transport and assembly can be achieved at any time.
- the diameter of the connecting rods 25 results from the static requirements.
- Commercially available iron pipes are preferably used as connecting rods 25.
- Each prefabricated component 26 comprises a plurality of connecting rods 25, which run across all hollow beams 1.
- each hollow beam 1 has continuous round bores 27 arranged on both side walls 7 at regular intervals. The diameter of all these bores 27 corresponds to the outside diameter of the connecting rods 25.
- care must be taken to ensure that an intermediate space 28 remains between each hollow beam 1 and the hollow beam 1 adjacent to it. This can be accomplished, for example, by inserting spacers between the hollow beams 1 during the manufacture of a prefabricated component 26 (not shown). The spacers can be formed, for example, by short wooden strips. After the completion of a finished component 26, the spacers are then removed again.
- Short pipe pieces 29 are used to connect two prefabricated components 26, the outer diameter of which corresponds to the inner diameter of the connecting rods 25.
- a short pipe section 29 is partially pushed into each connecting rod 25 of one of the prefabricated components 26 to be connected.
- the protruding section of each short pipe section 29 is inserted into a connecting rod 25 of the second prefabricated component 26 to be connected.
- FIG. 7 shows a prefabricated component 26 which comprises ten hollow beams 1.
- the hollow beams 1 are arranged side by side. They run parallel to one another and lie in one plane.
- the width of the hollow beams 1 is 19 cm in the exemplary embodiment.
- the distance between two adjacent hollow beams 1 is 4 mm. This results in a total width of the prefabricated component 26 of 193.6 mm.
- the connecting rod 25 used in the exemplary embodiment is formed by an iron tube with an outer diameter of 30 mm and an inner diameter of 24 mm.
- the diameter of the through bores 27 in the hollow beam side walls 7 also measures 30 mm.
- the outside diameter of the pipe pieces 29 used to connect two prefabricated components 26 measures 24 mm.
- a strip (spring) 18 is inserted into the mutually facing longitudinal grooves 11 on the lower wall of two adjacent hollow beams 1.
- This strip 18 has a purely decorative and no constructive, load-bearing function. It hides the gap between the two adjacent hollow beams 1. The total forces acting when the hollow beams 1 bend are caused by the dowels 2, 3 added.
- connection system for beam-shaped wooden construction elements is not only suitable for ceiling and floor constructions, but also for gable-shaped roof structures or wall constructions.
- a commercially available hydraulic wood glue binder press with pivot arms 21 and vertical holding posts 22 is preferably used. Both the swivel arms 21 and the support posts 22 are arranged on a line at regular intervals. In the swung-up end position, the swivel arms 21 run parallel to the vertical holding posts 22. The swivel arms 21 can be swiveled down into an approximately horizontal end position. The pivot arms 21 can be locked in any intermediate positions between these two end positions.
- the hollow beams 1 are assembled on the swivel arms 21.
- the swivel arms 21 are locked in an intermediate position for this purpose. They form a kind of work table, the work surface of which is inclined to the rear.
- each pivot arm 21 On the end face which, in the pivoted down position, faces the holding post 22, each pivot arm 21 carries a flat iron 23 which projects from the top of the pivot arm 21.
- the proposed hollow beams 1 are produced in the following way:
- the base plank 19 of a first hollow beam 1 is provided on two sides with two strips of glue 24.
- the glue strips 24 adjoin the edges of the corresponding broad side.
- the base plank 19 is placed on the swivel arms 21 in such a way that the broad side thereof lies against the flat iron 23 of the swivel arms 21 without glue strips 24 and stands on the swivel arms 21 with one of its narrow sides (cf. FIG. 5a).
- the first side wall 7 is then placed on the swivel arms 21. It is arranged in such a way that it abuts with a narrow side on the broad side of the base plank 19 which carries the glue strips 24 and faces away from the flat iron 23 (cf. FIG. 5b).
- a cardboard frame 10 can, for example, be made from a cardboard strip which has four transverse folding seams and whose two ends are glued together (see FIG. 6). Each cardboard frame 10 lies with a broad side against the base plank 19 and with a narrow side against the first side wall 7 of the hollow beam 1 (cf. FIG. 5c).
- the cardboard frames 10 are arranged at intervals of 1 to 2 meters.
- the second side wall 7 is placed on the upper narrow sides of the cardboard frame 10 in such a way that its narrow side touches the broad side of the base plank 19 which has the glue strips 24 (cf. FIG. 5d).
- the cover plank 20, like the base plank 19 is provided with two strips of glue 24 on one broad side. It is then placed on the swivel arms 21 in such a way that it stands with a narrow side on the swivel arms 21 and its broad side provided with glue lies against the end faces of the side walls 7 (cf. FIG. 5e).
- the first hollow beam 1 is thus assembled.
- further hollow beams 1 are assembled in the manner described until the swivel arms 21 are covered with hollow beams 1 along their entire length (cf. FIG. 5f).
- the swivel arms 21 are then swiveled into their vertical end position. When they have reached this end position, the hollow beams 1 lie one above the other. In addition, they rest with the one side wall 7 on the swivel arms 21 and with the other side wall 7 on the vertical holding posts 22 (cf. FIG. 5g). Finally, a pressure is exerted on the hollow beams 1 from above and from the side until the glue has hardened sufficiently.
- the hollow beams 1 are then removed from the wood glue binding press.
- the side walls 7 are provided with the bores 12, 13 which serve to receive the dowels 2, 3.
- the cardboard frame 10 has only the task of the base plank 19, the top plank 20 and the side walls 7 of a hollow beam 1 to keep in the correct position before pressing.
- the proposed connection system makes it possible for the first time to absorb the lateral dilation of beam-shaped wooden structural elements arranged next to one another. This can prevent damage to buildings caused by dilation.
- the dowels 2, 3 of the proposed connection system act like transverse struts, which make it more difficult for the hollow beams 1 to bend.
- the dowels 2, 3 connect adjacent hollow beams 1 to one another. If a hollow beam 1 bends in the longitudinal direction, it pulls the two adjacent hollow beams 1 with it. The formation of steps between the hollow beams 1 can thereby be reliably prevented.
- the springs 18 have a purely decorative and no supporting function.
- the static tasks are carried out exclusively by the dowels 2,3.
- the dowels 2, 3 of the proposed connection system can be assembled easily and quickly and in no way hinder the joining of the wooden structural elements. They can be inserted into the bores 12, 13 of the wooden structural elements without great application of force.
- the long dowels 2 are screwed together in a simple manner. This can be done particularly quickly with the help of a hand drill and the special screw attachment.
- the proposed prefabricated building elements 26 are delivered to the construction site ready for use. This significantly reduces the workload on the construction site.
- the cardboard frames 10 used for the assembly do not impair the making of the round bores 12, 13 in the side walls 7 of a hollow beam 1. Furthermore, they have the advantage that they do not prevent lines from being drawn into the interior of a hollow beam 1. This disadvantage occurs in known hollow beams 1, which with help during the opening fe of wooden transverse walls can be stabilized.
- Another advantage of the cardboard frames 10 is their small space requirement. They can be stored to save space.
- decorative, load-bearing ceilings can be built. It can be used, for example, to simulate panel ceilings or shadow gap ceilings.
