Description

Method for producing a construction with a structural component, in particular egg ner wall, a ceiling or the like, formed by a plurality of interconnected wooden panels, structural component, a wall produced by this method and a Ver bond s e 1 eme n t for wooden panels.

The present invention relates to a method for producing a construction with a structural component, in particular a wall, a ceiling or the like, formed by a plurality of interconnected wooden panels, structural component, for example, a wall produced by this method and a Ve rb in You ngse 1 e me nt for wood panels, in particular wood panels with glued or mechanically connected, for example, XLAM or CLT cross layers for producing such a Wan dung.

By "essentially" angular deviations of + - 5 ° are meant.

There are numerous elements known for the connection of wooden panels. The biggest problem is in the production of an element that is easy to assemble during assembly, as all the required strength and stiffness characteristics are extremely high. Furthermore, a monolithic behavior of the connected wood panels is required. Due to the monolithic feature, a plurality of wooden panels behave like a single wooden panel that can only be attached to the ends by attaching them, avoiding tilts and not having to fix each individual panel of wood.

From WO 2012 13 96 01 Al a kit for surfaces is known, comprising a plurality of wesent union rectangular panels, each panel as of an upper and a lower surface and sidewall comprises. The side walls have ge opposite openings to use a cross-section cross-section having connec tion element.

The connection thus produced can not be isolated, and due to the necessary play, stable form coupling is not possible, and thus no monolithic structure of the wood panels can be achieved.

In the publication WO 2012 13 96 01 Al, no approaches are described for achieving uniform rigidity and strength in the wood panel. A connection is made to connect the panels outside the plane of the laminate parquet or wallboard, respectively.

From the KR 10-1060983 is an element for the connection of wood panels Ver known. Also in the Korean patent application for joining wooden panels is sunk in the panel. Also in this case, no stable form coupling is possible, with no monolithic

Structure of the panels can be.

DE 10044016 describes a device for connecting Fuß bo de ntafe 1 n with a wood core, in particular mdf or hdf, wherein at least a portion of a sc hw a 1 bens chw-like groove has, which a second panel with a gespie s chw a 1 bw chw förmi ge groove opposite and wherein these panels are connected by means of a connection se 1 eme nt without games. The connection described requires a high level of precision and is intended only for connections of foot floors, installation after laying the panel is not possible. The publication WO 20017089309 describes a component formed of two components, which are facing away on its opposite narrow side, which comprises a plurality of bars in the first one, which connect the preloaded components, and wherein the components have rear-cut recesses in which the vines grown by means of two wood chips are used in one piece. In the joint between the two components, the undercut element has a lower strength and is therefore exposed to a high risk of breakage in the connection. The publication WO 2014153574 describes a component formed by two panels, which are connected along the entire width by means of, for example, two wedge-shaped parts which connect to one another. The connection is a linear one in that it has the disadvantages that it has no resistance and rigidity against shearing stresses in the panel level.

The walls made of wooden panels can also be designed with single panels. However, this implies a series of home, storage, transport and door s p rt p r ob e s i n e given by the dimensions or weight of the walls. Furthermore, each wall generally has specific dimensions that prevent mass and standard production. This problem is often solved by producing panels of a moderate and standardized width that can be used in the factory or at the construction site. The prior art panels are assembled with screws which operate under shear, possibly by interposing a plate. This compound does not allow to obtain a sufficient rigidity level. These systems do not allow this to clamp the panels together.

EP 088 601 describes a dowel for the United bond of two panels. This dowel is formed with a uniform cross-section and in which the outer parts are wider in order to To be clamped the openings, the Ausspa ments have. The dowel described is intended for the connection of two panels, but only with one sealing element and not with the formation of a pivot in the hinge, which only has to be braced with, for example, tensioning means such as screws and the like 11 t will. Moreover, as explained in the subject matter, the dowel is intended to join panels which have inner space 1 in their interior I and which are therefore not structurally, but which are only 1 so. Moreover, the recess formed in the receptacles of the panels does not allow to create a tensile force between the panels. The compound described in this publication does not allow a monolithic structure to be formed between the two sheets.

EP 0 117 205 describes a method for the connection of two panels. Also in this case, the two panels have a recess to allow the hinge to be fastened within this recess. The compound is also introduced from top to bottom along the entire contact area between the two panels is. Also in this case, it is not possible to introduce clamping means to fix the two panels and to form in this way a monolithic structure. Also in this case, the connection to the outside is not described for the formation of a tensile structure, the is essential to calculate the statics of a construction.

WO 00/20705 describes a connection between two panels, in particular for the formation of a floor. Also in this case, a connection with a recess is described, which allows to clamp the connection düb e 1. Also, this structure does not have the monolithic features of the compound and, moreover, it is not intended to have structural characteristics.

The problem that is solved by the method described in the present description to derive a structure having interconnected panels forming a monolithic unit and the connection at the bottom via tension members allows a rapid and reliable calculation of the statics of a Structure, whereby the calculations can be limited to the predetermined draw locations and where the structure for each individual panel or part of the panel need not be calculated and dimensioned, but only for the entire structure, thus providing a more efficient one and faster construction will be reduced, where the costing costs are reduced and the more efficient use of the calculation systems is allowed.

FIGS. 4a and 4b show a blanket produced according to the invention, with the forces 103 shown in FIG. 4b, to which the individual panels are exposed, and the blank, as shown in FIG Links. The monolithic behavior of the ceiling allows damage to the ceiling Building due to an earthquake or the like.

For the execution of an invention according to the method, in a first step cavities 20, 20a and 20b in wooden panels 1, 2, 3, in particular in panels XLAM or CLT or similar, are sent to one of the surfaces 4, 5 of the pas produced the wall to be created panels 1, 2, 3.

In an outdoor f o rm, these panels consist of at least three tiles 11a ng / s chiches or boards. The sheet layers are superimposed and connected to each other so that the fibers of each layer 21, 22, 23, 24 and 25 are pivoted in the panel plane by 90 ° with respect to the adjacent layers or in general the panels of FIG like to make wood.

These cavities 20, 20a and 20b are made for example by means of a CNC or on a portable machine at the construction site, which mills a recess or opening at the adjacent edges of the panels 1, 2, 3, and thereby forms the cavities. The cavities 20, 20 a and 20 b are not continuous for panels of larger width in the direction perpendicular to the surface of the wall direction. In these cavities 20, 20a and 20b, the container is pressed into a ngse 1 eme nt 7, 17, which by a Me ta 11 e 1 emen t or a fa Polymer is formed, which is a

Row from to the board level Ribs 7 a 7 b, 7 c, 7 d, 7 e, which are advantageously each of the panel 1, 2, 3 forming wood layer 21, 23, 23, 24 and 25 are arranged. For example, for a multi-layered board Xlam, five ribs, the bottom surface of the board in front of one another 7, 17 are present in an open space. These ribs 7a, 7b, 7c, 7d, 7e can be dimensioned depending on the orientation of the wood layer. The most heavily loaded ribs may be formed with greater strength to better resist or, if the panel is formed of only three layers, the groove may also be five ribs 7a, 7b, 7c, 7d in the same way. 7e have. In this case, two ribs work together to absorb the stresses of a wooden layer 21, 22, 23, 24, 25.

After insertion, the box is placed in du ngse 1 eme nt 7, 17 without play in a direction perpendicular to the vertical axis. After insertion of the joint 1 e me nets 7, 17, the screws 11 are screwed into the seats 12 of the housing 1 me me ntes a ge to the two panels 1 and 2 with the Einan without tension to play and on this way to create a monolithic structure. With the bracing by the anchoring of the screws, the vertical gap between the panels and with the introduction of a foam, this attachment is supported. Advantageously, a plurality of rails are used in the doorway 1, 7, 17 for connecting the panels 1, 2. Advantageously, the wheels of the invention have an inclination of substantially (which is understood to be substantially + -5 °) between 30 ° and 70 °, preferably 60 °. Advantageously, they can also be introduced so that at least two layers of wood 22, 23 fibers under different orientation of the wood are claimed. In this way a greater resistance to stress is achieved.

Advantageously, the seats 12 have a groove for receiving chafing cushions / s p a n n e 1 s e n e s 11.

As shown in Figures 14a, 14b, 14c, the gap 8 is present during the insertion of the Ve rb in du ngse 1 eme ntes 7, 17 and with the Einbrin movement of the screws 11 and their bracing by means of anchoring is in the figure 14c Darge provides as the gap 8 is closed and the two wooden panels therefore have a monolithic Ver hold. In a second step, an insulating agent may be introduced, for example, a polymer, a resin, or the like, to insulate the bond. This is also an aid to the attachment of the first and second embodiments.

Preferably, the beams are formed in a hollow manner with inner ones Ribs to give the element a greater rigidity, while the whole element still remains light. Advantageously, the compounds are made of metal, in particular aluminum, by extrusion or pultrusion of reinforced polymer.

 The hub 7, 17 preferably has a wedge shape to facilitate insertion into the cavity 20. In particular, only the end part of the connecting part 7, 17 is wedge-shaped, i. E. the first part that is brought in.

The openings of the containers 1, 1, 7, 17 are advantageously filled with the saucepan 1 a.

In the subsequent step, a B a n d / K 1 eb e n d d is attached to the opening 20 such that the connection is sealed. Advantageously, the tape is bonded along the entire contact area of the sheets on both sides. In this way, the gap between the panels, which could be present, is also sealed. The tape may be an adhesive tape provided for the tape.

In a preferred embodiment, the cavity 20, 20a, 20b is closed in wood prior to laying the band 20 by means of a twisting mechanism, for example a plug, preferably in wood. A structural component which is the largest in this type of process and having an element according to the invention has considerable advantages, since it can be assembled with panels with solar immersion and nevertheless displays the features of a single panel ä 1 t. This structural component is not only more economical to manufacture, because it can be used as well, but is also easier to transport.
