Abstract

The wall for a building structure, especially a non-load bearing inner wall (1), is composed of a number of butting plywood timbers (3) forming flat frames (5). The frames are covered by planks (7). The timbers have grooves (15) along their longitudinal sides (13), at right angles to the frame planes. Bonding units (21,31,37) grip into the grooves, with a width matching the groove width, to adjust and align the butting timbers across the frame planes.

Description

The invention relates to a building wall with a multi-butt abutting, constructed in cross-section substantially rectangular wooden bars, planar frame, a fixed to the frame planking on at least one of the flat sides of the frame and connecting elements at the joints of the wooden latch.

Building walls of this type are commonly used as non-load-bearing interior walls. The frame consists of mostly planed and dried solid wood bars and is fitted on both sides with cladding panels e.g. Plasterboard or wood-based panels planked. To connect the wooden bars conventional pin connections or sheet metal fittings are provided or the wooden bars were connected by obliquely driven nails or screws. However, the naturally grown square timber bars tend to warp. The hitherto conventional connections require some skill in the art, if misalignment or excessive dimensional tolerances of the frame to be avoided.

In order to avoid such unwanted deformations of the frame, it is also known to build the frame of sheet metal profiles, which in turn are planked with plasterboard or wood-based panels. But even with sheet-metal profile frame some manual skill for a professional result is required, so that this type of building walls can be used only limited in the home improvement sector. In particular, special tools are often required for processing the sheet metal profiles.

Out DE 25 01 330 A1 is a built-up in the "do-it-yourself" method wall element with a built up of several butts abutting, rectangular wooden bars built, planar frame, which is planked at least on a flat side of the frame. The wooden bars are designed as solid wood bars and have over their entire length extending dovetail grooves. At the joints they are attached via dovetail fasteners to each other, which are threaded during assembly of the frame in the dovetail longitudinal grooves of the bolt to be connected.

Out FR 2 815 654 A1 It is known to build the bars of a wall frame made of boards glued together. The glued together boards have different widths and form between the cover boards longitudinal grooves, which engage in the frame ausfachende wall plates.

It is an object of the invention to provide a building wall, which can be constructed in a very simple manner and with the simplest tools. In particular, the accuracy with which the building wall can be built, to be increased so that it can be constructed by less experienced persons, and also the building wall should be transverse stiffness.

The inventive features of such a building wall are specified in claim 1.

In such a building wall, the timber bars are designed as laminated wood latches in the form of laminated veneer lumber bars or plywood latches, which do not distort substantially. The stacking direction of the layers of laminated timber bars runs along the frame plane, whereby the layers extend transversely to the frame plane. This leads to a particularly high transverse stiffness of the building wall. In addition, the laminated timber bars can be produced in this way in different widths from plywood panels.

In addition, since the engaging with their connecting portions in the longitudinal grooves of the laminated timber fasteners align the laminated timber transversely to the frame plane, flat frame can be built without misalignment at the joints. The building wall can be used both in the professional area as well as in the DIY sector. To cut to length the laminated timber, a conventional saw is sufficient. For the connection of the laminated timber provide the prefabricated fasteners that can be provided with holes for fixing nails or screws for fixing to the laminated timber bars. It is understood that the connecting elements, as usual in such building walls, only need to absorb part of the wall loads. The final stability of the building wall is achieved by the subsequent planking, which is attached to the Schichtholzriegeln, for example, nailed or screwed.

In principle, it is sufficient if longitudinal grooves are provided in only two of the longitudinal sides of the laminated timber bars over their entire length. Preferably, however, such longitudinal grooves are provided in all four longitudinal sides. In this way, corner joints can be made.

In order to be able to attach several connecting elements transversely to the frame plane next to one another in the case of thicker building walls, it is provided in a preferred embodiment that a plurality of mutually parallel longitudinal grooves are provided in pairs opposite longitudinal sides of the laminated timber.

Conveniently, the longitudinal grooves have the same width and / or depth, so that uniform connecting elements can be used. It has proved to be advantageous if the longitudinal grooves have a width and / or a depth between 5 and 15 mm. With dimensions of this type, the cross-section of the laminated timber bar is not weakened too much, and yet the remaining groove cheek is sufficiently strong to guide the laminated wooden bar across the frame plane at the connecting sections.

The laminated wooden bars have expediently in the direction of their layer stack a thickness between 33 and 75 mm and in the layer direction a width between 40 and 240 mm. In order to be able to accommodate a sufficiently large number of layers, the thickness of the individual layers should be between 1.2 and 3.3 mm. Especially with veneer lumber bars, the layer thicknesses should be between 2.9 to 3.3 mm.

For a sufficiently high load-bearing capacity of the laminated timber bars, the grain direction of the majority of the wooden layers of the laminated wooden strips runs at least approximately in the longitudinal direction of the laminated wooden bars. Although the grain direction of all the wood layers of the laminated timber bars preferably extends in their longitudinal direction, it is understood that a part of the layers having a fiber direction extending transversely to the frame plane can be incorporated to reduce the twisting tendency.

The connecting elements can be constructed differently. The various variants have in common that they align over their connecting portions of the blunt-ended laminated timber transverse to the frame plane relative to the cross-laminated wooden latch substantially aligned, so that when assembling the frame only the position of the blunt end plywood bolt along the transverse plywood bolt according to the desired dimensions needs to be adjusted.

In a preferred embodiment, it is provided that the connecting portions of the connecting element form an elongated connecting plate, whose width is substantially equal to the width of the longitudinal grooves and which is inserted into the longitudinal groove of the butt-end plywood bolt and engages with one of its longitudinal ends in the longitudinal groove of the crossing plywood bolt , From one of the longitudinal ends of the connecting plate, here the longitudinal end engaging in the longitudinal groove of the crossing plywood bolt, there is preferably a spike in the longitudinal direction of the connecting plate, which engages in the transverse plywood bolt. The mandrel can be a nail-like extension which is driven into the cross-laminated timber during installation of the connection plate. In such a connecting element is a simple and inexpensive to produce component.

In a variant, it can be provided that the connecting elements are designed as connecting angles with transverse to each other, the connecting portions forming tab legs for engagement in the longitudinal grooves of the laminated timber. Also in these fasteners are simple and inexpensive to produce components. In addition, the tab legs can be stiffened in the frame plane by a Stützzwickel.

Particularly stable are embodiments in which the connecting elements are designed as substantially U-shaped connecting brackets, projecting from the staple web two intended for engagement in the longitudinal grooves of the butt-end plywood latch tab shackles, wherein the staple bar for engagement in the adjacent longitudinal groove of the crossing plywood bolt is determined and the clip web and the tab legs form the connecting portions.

In order to ensure sufficiently deep penetration of the staple web into the longitudinal groove of the crossing plywood bolt, at least one contact surface intended for abutment against the end of the blunt plywood bolt can be provided in the area of the staple web, which holds the staple web at a distance from the forehead. The contact surface may be formed by a projection of the staple web, but also by a bent out of the tab legs nose or the like. For example, the clip web may be provided to the tab legs with at least one indentation forming the contact surface.

The above-described connecting elements have a band-like structure with the width of the longitudinal grooves, which can be substantially completely sink in the longitudinal grooves. It is understood, however, that the connecting elements can laterally overlap on the side surfaces of the laminated timber bolt, in particular on both sides of the longitudinal groove.

Such laterally over the connecting portions projecting portions can be exploited for stiffening of the connecting element and / or for fixing the connecting element to the laminated timber.

In a preferred embodiment of the last-explained variant, it is provided that the connecting elements have a base plate at least partially overlapping the end of the butt-end plywood bolt, from which at least one tab leg projects transversely into engagement with the longitudinal groove of the butt-end plywood bolt and from which to engage the longitudinal groove of the crossing plywood bolt projects transversely on at least one connecting web on the side facing away from the tab leg, wherein the tab leg and the connecting web form the connecting portions of the connecting element. Conveniently, two tab legs protrude from the base plate for engagement in the longitudinal grooves of the butt-end plywood bolt. The base plate rests on the forehead of the butt-end plywood bolt and can thus compensate for unevenness of the forehead resulting from cutting the plywood bolt to length.

The connecting web can be a connecting web pressed out of the base plate, the edges of which can run along the longitudinal groove of the cross-sectional laminated wood bar being cut free from the base plate in order to achieve a closely fitting guide surface.

A variant of the above-described fasteners, which is adaptable to laminated wood bars of different thickness, is characterized in that the base plate comprises two slidably guided along the cross-plywood slat plate sections, one of the plate sections one of the tab legs and the other plate portion of the connecting web and another has the tab legs. An adaptation of the fasteners to laminated wood bars of different width, for example, then required if the laminated timber bars do not collide at right angles but should be installed at an angle to each other. In this case, the end face of the butt-end plywood bolt runs obliquely and, accordingly, the distance of the longitudinal grooves along the oblique end is increased. It is understood that in this case, the tab legs must be bent according to the inclination, as is required in the above-explained fasteners when they are to be used in an oblique stroke. The connecting elements are therefore preferably designed as sheet metal bent parts or sheet metal stampings. It is understood, however, that the connecting elements can also be designed as plastic molded parts.

The subject matter of the invention includes not only the above-mentioned building wall, but also a construction kit for building a frame of a building wall of the above-explained type. The construction kit includes semi-finished laminated timber and at least one connecting element for the butting joint of separated from the semi-finished Schichtholzriegeln laminated wood cross-sections. The semi-finished laminated timber bars can be offered commercially in predetermined lengths, for example a length of several meters.

The Fig. 1 to 3 show a building wall 1 with an elongated, in cross-section substantially rectangular-shaped Schichtholzriegeln 3 constructed, planar frame 5, at least on one of its flat sides, but preferably carries a planking 7 on both sides. The planking may be plasterboard, wood-based panels or the like, but also a planking act. The laminated timber 3 are stumped at the joints 9, ie each one of the laminated timber 3 ends bluntly at a cross his forehead other laminated timber bar, as this easily Fig. 1 shows.

The layers 11 of the laminated timber 3 are stacked in the direction of the plane of the frame 5, so extend with their layer area transverse to the frame plane. The laminated timber 3 have substantially rectangular cross-section and are at least at their transverse to the frame plane side surfaces 13 all arranged centrally, over the entire length of the laminated timber 3 extending longitudinal grooves 15 are provided. In the same way in the longitudinal direction of the frame plane extending side surfaces 17 of the laminated timber 3 are incorporated centrally and over the entire length extending longitudinal grooves 19.

The laminated timber 3 are fixed to each other at the connection points 9 by connecting elements. The FIGS. 2 and 3 show a first embodiment of these fasteners, here in the form of a connecting angle 21 with transversely extending tab legs 23, the width of which is substantially equal to the width of the longitudinal grooves 15. Inserted in adjacent longitudinal grooves of the adjoining laminated timber 3, the connecting angle 21 fix the stump ending laminated timber 3 to the plane of the frame 5 in alignment with the junction 9 crossing plywood 3. In the tab legs 23 through holes 25 are provided, through which the connection angle 21 at the Schichtholzriegeln 3 can be nailed or screwed.

The connecting angle 21 may be sheet metal bent parts made of a metal strip, if necessary, as shown in FIG Fig. 3 indicated at 27 between the tab legs 23 a Stützzwickel be provided. It is understood that the connection angle 21 may optionally be formed as a plastic molding.

The longitudinal grooves 15, 19 have expediently a width and / or depth between 5 and 15 mm and extend over the entire length of the laminated timber 3. The laminated timber 3 can thus be easily made by sawing off bar sections of laminated timber semi-finished product. For the construction of the frame 5 no special technical knowledge is required because the connection angle 21 for alignment alignment of the laminated timber 3 provide at the connection points 9. Since the elements of the frame 5 are made of laminated wood, they essentially do not twist. In the direction of their layer stack, the laminated timber bars 3 are preferably between 33 and 75 mm thick. Transverse to the plane of the frame 5, the laminated timber bars 3 have a width between 40 and 240 mm. It is preferably veneer lumber bars or plywood bars whose individual layers are between 1.2 and 3.3 mm thick. For veneer lumber logs, the layers are desirably between 2.9 and 3.3 mm thick.

The frame 5, as usual in the walls in question, be filled with insulating material. In unoccupied longitudinal grooves may additionally tubes, cables, cables and the like may be inserted, as in Fig. 2 indicated at 29.

As will be explained in more detail below on the frame 5 in FIG Fig. 1 provided different types of connecting elements for connecting abutting plywood bolt. It is understood that all fasteners but can also be of the same type, for example, all joints using the basis of FIGS. 2 and 3 explained connection angle 21 can be fixed relative to each other.

Fig. 4 shows a variant of a connecting element in the form of an elongate connecting plate 31, whose width is substantially equal to the width of the longitudinal grooves 15. The connection plate bears on one of her Longitudinally projecting nail mandrel 33 and is driven with the nail mandrel 33 in the transverse laminated timber 3. The main part of the connecting plate 31 is located in the longitudinal groove 15 of the butt-end plywood bolt 3, but engages with its nail mandrel 33 bearing longitudinal end in the adjacent longitudinal groove 15 of the crossing plywood bolt 3 a. Not shown in detail is a variant in which the connecting plate 31 carries on the engaging in the longitudinal groove 15 of the crossing plywood bolt 3 end an L- or T-shaped head. Also, the connection plate 31 is provided with through holes 35 for nailing or screwing. Advantage of the connecting plate 31 is that it extends substantially only in one direction and thus can be used even with obliquely poking Schichtholzriegeln 3, as in Fig. 1 is shown.

The FIGS. 5 and 6 show a further variant of one in the structure of the frame 5 in Fig. 1 usable connecting element, here in the form of a U-shaped connecting bracket 37, 39 of which two tab legs 41 protrude parallel to each other for engaging in the longitudinal groove 15 of the cross-sectional laminated timber 3 staple web. The tab legs 41 engage in the longitudinal grooves 15 of the butt-end plywood bolt 3, wherein their distance is equal to the distance of the groove bottoms of these longitudinal grooves 15. The width of the staple web 39 and the tab leg 41 is substantially equal to the width of the longitudinal grooves 15th

The connecting brackets 37 are bent from a metal strip bent sheet metal parts. In the grooves at the transition of the staple web 39 in the tab legs 41 indentations 43 are formed, which bear against the front of the blunt end plywood bolt 3 and hold the staple web 39 at a distance from the forehead. In this way, it is ensured that the clip web 39 dips as deeply as possible into the longitudinal groove 15 of the crossing plywood bolt 3, which benefits the stability of the connection. Not shown in detail are through holes in the Laschenschenkein 41 and / or the clip web 39, for fixing the connecting bracket 37 to the laminated timber 3.

The above-explained connecting elements have a total width corresponding to the groove width of the longitudinal grooves 15. In the FIGS. 7 and 8 is another, clamp-shaped connecting element 45 is shown. The connecting element 45 is formed as a stamped sheet metal part and comprises a base plate 47, are cut free from the two tab legs 49 and bent in the same direction transverse to the base plate 47. Between the tab legs 49, a connecting web 51 is cut free from the base plate 47 and pushed out of the base plate 47 on the side facing away from the tab leg 49. Similar to the connection bracket 37 of FIGS. 5 and 6 engages the connecting element 45 with its tongue legs in the longitudinal grooves 15 of the butt-end plywood bolt 3, while the connecting web 51 engages in the adjacent longitudinal groove of the cross-plywood bolt 3. The base plate 47 comes here to lie between the laminated timber 3. On the base plate 47 as well as optionally the tab legs 49 are again provided through holes 53 for Fixierungsnägel or screws.

As in Fig. 1 shown, the laminated timber 3 must not collide at right angles at the joints. To adapt to a roof slope or the like, the laminated timber 3 can also run obliquely to each other. However, based on the then obliquely extending end of the butt-end plywood bolt 3, the oblique distance of engaging in the longitudinal grooves 15 of the butt ends plywood bolt connecting elements changes. While the distance in the embodiment of the connecting plates 31 of Fig. 4 can be easily compensated, it requires additional measures in staple-type fasteners. The FIGS. 9 and 10 show a variant of the connecting element of FIGS. 7 and 8 which is different from the connecting member 45 in that the base plate is divided into two base plate portions 47a and 47b facing in the direction of Longitudinal groove 15 of the crossing plywood bolt 3 are slidably guided together. On the base plate portion 47 a of the tab legs 49 and the connecting web 51 is formed, while the other base plate portion 47 b carries the other of the two tab legs 49. In contrast to the connecting element 45 of FIGS. 7 and 8 The connecting web 51 projects freely from the base plate portion 47a and engages in a recess 55 of the base plate portion 47b which is open toward the base plate portion 47a. In this way, the base plate portions 47a and 47b are slidably guided against each other and the distance of the tab legs 49 is adjustable. Also, the connecting element 45 'is in turn provided with through holes 53 for fixing to the laminated timber 3.

For the connection obliquely to each other piling laminated timber 3 and the tab legs 49 extend obliquely to the base plate portions 47 a and 47 b. It is understood that the tab legs 49 of the connecting element 45 'can also protrude at a right angle from the base plate sections 47a and 47b, so that the connecting element can also be used for laminated timber bars 3 of different thickness. Optionally, the angle of the tab legs 49 may also be subsequently bent into the desired angular position.

Fig. 11 shows the cross section through a variant of a plywood bolt 3 ', which differs from the above-explained laminated wood bolts in that a plurality of mutually parallel longitudinal grooves 15 are incorporated in its transverse to the plane of the frame 5 side surfaces 13. The longitudinal grooves 15 extend mirror-symmetrically to the longitudinal center plane of the flat sides 13. The laminated timber 3 'allows the attachment of multiple fasteners per joint, which the stability of the frame 5 in thicker walls benefit.
