Abstract

Disclosed is a wooden structural part for erecting walls, which can be positively joined to adjoining wooden structural parts. Said wooden structural part comprises at least one inner piece (2) and wall pieces (1, 14, 17). Spaced-apart projections (5) are disposed on a top face of the inner piece (2) while recesses (6) for accommodating the protrusions (5) of an adjoining wooden structural part are arranged on a bottom face that lies opposite the top face. The inner piece (2) is provided with pegs (5) as protrusions. The extension (x) of said pegs (5) in the longitudinal direction of the wooden structural part corresponds to the extension (x) thereof in the transversal direction of the wooden structural part while the distance (y) between two adjacent pegs (5) corresponds to once or an integer multiple of, preferably twice, the thickness (y) of a wall piece (1, 14, 17). The advantage of the invention is that the sidewalls of a wooden structural part that is placed on another wooden structural part at a right angle rest directly on pegs of the superimposed or subjacent wooden component, resulting in an extremely stable connection, especially in corner areas or joining areas.

Description

Wooden component - 1 -

The invention relates to a wooden component for erecting walls, which is positively connected to adjacent wooden components and consists of at least one inner part and wall parts, wherein on the inner part at a top spaced projections and on an upper side opposite bottom recesses for receiving the projections of an adjacent timber component are arranged.

From EP 744 307 A1 and EP 894 170 A1 building modules or a building module systems for the production of flat constructions, in particular walls, are known, in which each building module is assembled from a plurality of wood components. The individual building modules can in turn be joined together in the manner of a plug connection to walls and the like.

It is an object of the present invention to provide a simple solid wood component available, with the corner joints and wall connections can be made in a simple way.

This object is achieved with a wooden component with the features of claim 1.

The wooden component according to the invention consists of at least one inner part, which is to be understood with pins and recesses in order to create the positive connection with timber components lying above or below it. The distance between the individual pins and in a corresponding manner, of course, the recesses is chosen so that it corresponds to the simple thickness or an integer multiple, in particular twice, the thickness of a wall portion. In addition, the length of the pins corresponds to their width, i. they are preferably square. The advantage that results from this is that a wooden component, which is placed at a right angle on another wooden component, abuts with its side walls directly on pins of the wooden component lying above or below, whereby an extremely stable connection, in particular create in corner or connection areas.

In a preferred embodiment of the invention, which is characterized gekenn¬ characterized in that the wall parts project in the longitudinal direction of the timber member at an end face on the inner part and at the opposite ing end side are set back accordingly far, neben¬ lying timber components in the form of a tongue and groove joint mit¬ be connected.

If the distance between two adjacent pins e.g. equal to twice the thickness of a wall portion and the projection of the wall portions at one end corresponds to half the distance between two adjacent pins, then corner joints or Stoßverbin¬ can be created without gaps between the adjacent parts without it being necessary at least at one end to cut off a timber component or to close existing gaps or gaps with additional components.

In a corresponding manner, it is possible that the inner part has pins as projections whose extension in the longitudinal direction of the timber component of their extension in the transverse direction of the timber component corresponds and that the distance between two adjacent pins of simple thickness or an integral multiple, preferably twice, the thickness a wall part corresponds. In this way, an additional connection corresponding to a tongue and groove connection can also be created on superimposed wooden components, whereby a gap-free connection is ensured even between overlapping wooden components, so that a corresponding wind or diffusion-tightness of the wall component is also ensured.

Alternatively or additionally, it can also be provided that the wall parts have grooves and springs at their edges, d. h., That the wall parts of adjacent timber components are each connected to each other via tongue and groove joints.

A wall part can be single-layered or multi-layered. If the wall part is multi-layered, the individual layers of the wall parts can likewise be offset against each other, so that a kind of tongue and groove connection can be created in this way as well.

In a preferred embodiment of the invention, a wooden component has at least two inner parts arranged one behind the other in the longitudinal direction of the wooden component. The "core" thus consists of two in the direction Längs¬ the wooden component arranged one behind the other inner parts. As a result, even with longer wooden components, it is possible to arrange the wall parts with the fiber direction in the longitudinal direction and the inner parts with the fiber direction in the vertical direction, which positively influences the strength of the wooden component and also the shape-changing behavior of the wooden component as a result of temperature and moisture changes.

A preferred embodiment of the invention is characterized gekennzeich¬ net, that it at least two xn transverse direction of the wood component nebenein¬ other arranged inner parts, which are separated by a central wall vonein¬ other.

The inner parts with the pins and corresponding recesses are arranged in this embodiment two or more rows in the timber component, the middle wall between these two inner rows of parts for example has a wall thickness which corresponds to the distance between two pins of an inner part. This thickness of such a middle wall preferably corresponds to the single or double strength of the side wall, resulting in the already mentioned above advantage that the center wall and the side wall abut directly on the pin, which results in the high strength of the component composite.

It is also possible to create corner joints or T-joints of walls in which walls of single-row and double-row or multi-row wooden components adjoin one another, since these correspond in terms of their division in the transverse direction.

The middle wall can be single-layered or multi-layered. If the middle wall has two layers and the thickness of one layer corresponds to the thickness of a wall part, then the wooden component essentially consists of two juxtaposed simple or single-row wooden components which are connected to one another. Thus, multi-row wooden components can be produced, which, however, essentially always consist of only two basic components, namely wall parts and identical middle wall layers as well as inner parts which are joined together to form the corresponding wooden components.

In the case of the timber component according to the invention, the parts are preferably connected to one another by means of screws, dowels or the like. Ideally, screws and in particular dowels made of wood come into question, resulting in - A - has a component made exclusively of wood. On the other hand, however, it is also possible to produce individual parts, for example wall parts, from other materials, for example insulating materials, by, for example, producing a middle wall of heat-insulating and / or sound-insulating material. For multi-layer wall parts, for example, a layer of wood and another layer of heat and / or sound insulating material can be made.

Further preferred embodiments of the invention are the subject of the remaining dependent claims.

Further features and advantages of the invention will become apparent from the following description of embodiments of the invention with reference to the accompanying drawings.

FIG. 1 shows a first embodiment of a wooden component according to the invention, which consists essentially of two wall parts or side walls or side boards 1 and two inner parts 2. The wall parts 1 and inner parts 2 are connected via four wooden dowels 3 mitein¬ other, that each an inner part 2 is connected via two wooden dowels 3 with the two wall parts 1.

Each inner part 2 has a base body 4, to which two pins 5 are attached at the upper side and two recesses 6 at the opposite lower side. The pins 5 are square in cross-section and the recesses 6 have a corresponding cross-section, so that the pins 5 of a wooden component can be inserted into the recesses 6 of a wooden component arranged above. It is understood that the pins 5 could also be attached to the underside of the timber component and the recesses 6 at the top of the timber component, as this would not change the basic function of the positive connection of superimposed wooden components. Also, instead of square pins, e.g. also circular cones are used.

It can be seen in FIGS. 1 to 4 that the pins 5 protrude beyond the upper edge 7 of the wall parts 1 and the recesses 6 are accordingly in the interior of the wooden component between the wall parts 1 befin¬.

At the edges 7 and 8 of the wall parts 1 there are springs 11 and at the edges 9 and 10 are grooves 12 so that angren¬ zende wooden components can be connected to the wall parts 1 via tongue and groove joint tightly together.

As shown in FIGS. 1 to 4, the pins 5 have a spacing of 2 times Y, which corresponds to twice the thickness or thickness Y of a wall part 1. The length and width of the pin 5 in turn corresponds to the thickness or thickness X of an inner part 2. Finally, the inner part 2 shown on the right in FIG. 3 jumps by the length Y, again half the distance between two pins 5 via the edges 10 of the wall parts 1 in front. Correspondingly, the inner part 2 shown on the left in FIG. 3 is offset to the right by the dimension Y, that is, to the inside. That way longitudinally adjoining wooden components via a zwi¬ tween the side walls 1 and the inner parts 2 formed Nut-Feder¬ connection positively connected to each other.

FIGS. 5 to 9 show a corner composite consisting of 4 wooden components, from which it can be seen that a wooden component can be used without additional machining both for producing a straight wall part and also for an Ec¬ kverbindung. Since the distance 2 times Y between two pins 5 corresponds to twice the wall thickness Y of a wall part 1 and the internal parts 2 are also offset by the dimension Y in the longitudinal direction, the possibility of adding a standard wooden component also as corner joint part results without additional processing verwen¬ the. The wooden components adjoining one another in the horizontal direction in the illustrated corner region can be joined to one another without a gap. Only in the opposite corner region of every second row, it is necessary to shorten the inner part 2 so far that it ends flush with the side walls 1.

The embodiment of wood components shown in FIGS. 7 and 9 differs from the embodiments of the preceding figures in that the springs 11 at the upper edge 7 terminate at one end at a distance from the front edge 8 of the side walls 1. This makes it possible to fully set up in the corner area overlying wooden component. If necessary, this missing section of the springs 11 can either be removed on site or be missing by default in all timber components. In addition, in Fig. 9, the spring 11 on the front edge 8 was removed.

In the same way as the Eckver¬ shown in FIGS. 5 to 9 can be made bund, can also be a front side, i. T-shaped, connecting to a wall transverse wall in a stable composite herge¬ provides.

Of course, it is possible to produce the wooden component of Fig. 1 to 9 without grooves 12 and springs 11, since this indeed has an influence on the tightness of the wall but no significant effect on the strength of the composite of wood components. In the following figures 10 to 25 embodiments of Holzbau¬ parts are shown, which, in contrast to the single-row embodiment shown in Figures 1 to 9 have two juxtaposed rows of inner parts 2.

In the first embodiment illustrated in FIGS. 10 to 18, the two rows of inner parts 2 are separated from each other by a middle wall 14 whose width Y is the same as the width Y of the side wall 1. The distance Y between two adjacent pins 5 also corresponds to the thickness Y of a side wall 1 and middle wall 14, so that the side wall 1 and the center wall 14 can engage with a connection of two wooden components at an angle of 90 'exactly between the pin 5 of the adjacent timber components ,

In this embodiment too, an inner part 2 protrudes at a front end, in the present case at the front edge 10, by the dimension Y and is set back by the same amount Y at the opposite edge 8. This results in the longitudinal direction of the timber components again a groove-spring-like connection of adjoining wooden components. In order to produce a seamless corner joint, it is necessary in this embodiment of the invention to cut off the region Y of the inner part 2 or wall part 1, 14 which is overhanging at the respective end, if a wooden component adjoins this side at right angles.

As shown in FIGS. 10 to 18, the inner parts 2 are offset in height relative to the sidewalls 1 and the middle wall 14, so that the main body 4 of the inner parts 2 projects beyond the upper edge 7 of the wall parts 1 and 14. On the one hand, the displacement of the parts in the vertical direction against one another, on the one hand, naturally serves to improve the mechanical bond between superimposed wooden components, but is primarily intended to achieve one impermeable connection between superposed wooden components thought. By means of this displacement, however, it is also necessary to provide cutouts 16 in the wall parts 1 and 14 in the region of wood components overlapping one another at right angles, in which the inner parts 2 engage in the region of a corner or T-shaped connection. FIGS. 19 to 25 show a further embodiment of a two-part wooden component, in which the center wall 17 has twice the width Y as a side wall 1. In the illustrated Ausführungs¬ example, the center wall 17 is made of two layers 17a and 17b, but could also be made of a single board with the strength 2 times Y. The advantage . a two-ply embodiment is that the two center wall layers 17a and 17b may be designed in terms of their dimensions as the side walls 1, so that no additional part with other dimensions must be kept in stock and ver¬ works.

The distance between two pins 5 and the length of a corresponding projection 15 between two recesses 6 corresponds in this Aus¬ leadership example again twice the thickness of the wall parts 1 and the total thickness 2 times Y of the middle wall 17. The length and width of the pin is X. , as well as the strength of the inner parts 2. The inner parts 2 are seen in the longitudinal direction of the wood component again offset by the dimension Y of Wand¬ strength of the wall parts 1.

The advantage of this embodiment with a center wall with double wall thickness Y of the side walls 1 is compared to the embodiment of Figs. 10 to 18 with only simple wall thickness of the center wall is that gapless corner joints of the timber components without processing, i. To cut or cut the wooden components, can be made, as shown in Figs. 23 to 25 can be seen.

This embodiment of the invention consists essentially of two juxtaposed, interconnected, single-row Holzbau¬ share, as they can be seen in principle in FIG. Therefore, it is possible to form corner joints, T-joints or joints of walls piercing each other at right angles, without having to cut off the wooden components. In addition, such compounds of wood components of different wall thickness can be formed by a wall of eg einreihigen wooden components and a wall of eg zweirei¬ Higen wooden components abut each other or penetrate each other, since the division, ie the length or width X of a pin 5 and the Ab ¬ was 2 times Y of the pin 5 from each other, in the transverse direction of a Holbau¬ part of its pitch in the longitudinal direction corresponds. In this embodiment, it would of course also possible to offset the Innen¬ parts 2 relative to the side walls 1 and the middle wall 17 of the height or at the edges of the side walls 1 grooves or springs to form a higher density of the connection in the horizontal direction through the To create wall through, but with the result, either the offset in height portions of the inner parts 2 and the springs 11 to remove, for example, to chase, or in the side walls 1 and the middle wall 17 corresponding recesses for the protruding Ab¬ sections to create ,

Naturally, it would also be possible with the embodiment of a wooden component shown in FIGS. 1 to 5, instead of the grooves 12 and springs 11 on the side walls 1, to displace the internal parts 2 in the vertical direction, in order to provide a higher density in the region of the plug connection ,

In all embodiments shown in the drawings, all internal parts 2 had two pins 5 and accordingly two recesses 6. Of course, it is equally possible to provide only one pin 5 with a recess 6 or more than two pins 5 and recesses 6 on an inner part 2.

As shown in the drawings, it is in the embodiment with two pins 5 and two recesses 6 in any case advantageous if the screws or dowels 3 are not mounted in each section below the recess between two pins 5 and over a corresponding projection 15. Namely, when a timber member is cut along a line 18 (FIG. 3), the remainder 19 of the left inner part 2 remaining between the wall portions 1 of the right portion can be easily removed, thereby automatically forming a cutout in which the frontal projection of an inner part 2 is formed a subsequent Holzbau¬ part can be inserted.

In the last embodiment of the invention shown in FIGS. 26 and 27, a corner joint is shown, which is made of wooden components, which consists of a single-row inner part 2 and two-layer side walls 1. The inner layers Ib of the side walls 1 are offset so far upwards that they are substantially flush with the pins 5 complete. The outer layers Ia are further down so that they are substantially flush with the underside of the wood component. The outer and inner layers Ia, Ib are further offset in the longitudinal direction of the wood component, wherein the outer layers Ia terminate flush with the inner parts 2 at both ends, whereas the inner layers Ib are offset by half the distance between adjacent pins 5.
