EP2687651B1 - Method for the adjustment and/or attachment of wood panels or beams and a structure constructed using this method - Google Patents

Description

The invention relates to a method for adjusting and fixing wood panels or beams made of wood and a structure carried out by this method.

The movement and laying steps of components often have the problem of adjusting the components themselves and / or their attachment to other components. In particular, a temporary element often has to be fastened during transport, which allows the component to be attacked. This temporary element must then be dismantled at the construction site. The movement and attachment could damage the component. For panels, for example made of wood, the movement and fixing according to known procedures require long periods of time, since it is necessary to fix the panels together at the construction site, for example using metal brackets which are fastened using nails or bolts or the wooden panels can be fastened together using screws. Such known fastening processes require long times in the laying step, since each individual panel in the correct Position must be positioned by the operator and there are no systems that guide the panels in the correct position during the laying step.

The US 2 635 450 describes a connection device for building modules. This connection device is incorporated in the building modules. The connection device is inserted during the manufacturing process and can not be added in a second moment.

Also in the DE 829 053 a connection device is described which connects several components. Both connection devices require a complicated process for preparation and installation. Moreover, they do not allow complicated shapes, for example, to perform spatial nodes. The connection device is introduced into the component, whereby only a two-sided connection is allowed.

DE 829 053 describes a device for lifting and connecting large building panels or building panels with building parts. This device is provided directly on the edges of structural panels and must therefore be prepared accordingly to the plates or components with devices for engaging lifting members and possibly also for connection with already erected building panels or building parts. Such a connection element is also suitable for spatial nodes. The attacking means are suitable for transport on the connecting element and not directly on the component itself

Also in US 2011/047922 a component (panel) 50 is described in which an anchoring means is directly worked out, which could possibly also serve for transport. However, there is no connection member provided separately from the component itself to be connected to a lift member or alternately to another member. This document therefore has the same disadvantages as DE 829 053 also

In the DE 43 41 490 we described a connection system. This connection system is flat and spatially for connecting tensile or compression bars in timber and steel construction. DE 43 41 490 differs from the method of claim 1 essentially in that the carrier is not offset by holes located in a connecting element. Accordingly, the connection of the carrier, in contrast to claim 8, no connection element with holes.

From the US 5094059 is a folding half-timbered building known. This comprises a roof connector comprising an elongated timber structure connected by double hinges.
From the WO 2011 123873 is a connecting element known for connecting prefabricated elements for houses, wherein the connecting element has at least one end face connected to side surfaces. WO 2011 123873 differs from the method of claim 1 essentially in that the wood panel is not offset by holes located in the connecting element. Furthermore, the structure of wood panels of the WO 2011 123873 from claim 8 in that the corners are not bevelled. The invention allows a simpler attachment to various structures, with greater security in the formation of connections is ensured. Moreover, it allows to carry out more complicated structures.

The invention has as its object to carry out a method which allows the adjustment and fixing of a wooden panel or a carrier in a rapid, safe and accurate manner and allows a connecting element for carrying out this method.

On the wooden board or the carrier, a connecting element is attached. Before attaching the component material is removed or otherwise the surface is prepared so that the connecting element is supplemented. For example, on a rectangular panel, the corners may be removed to secure, for example, a triangular connector.

The attachment of the connecting element by means of anchoring elements. These anchoring elements may be, for example, screws or other known anchoring elements. The connector has holes to be hooked. For example, a continuous bore may be provided which is perpendicular to the anchoring elements. This hole can accommodate a bolt or a rope over which the connecting element is adjusted together with the component.
In a preferred embodiment, a plurality of connecting elements may be present on one component.

The method according to the invention further comprises the method steps of claim 1. Step 1: Prepare the wooden board or the carrier according to step a) of claim 1. This preparation can additionally consist in a positioning of the building part. In step 2a, a connector is positioned. This positioning is done on the first step processed surface, such as at a worn corner.

In step 2b, as described in step b) of claim 1, the connecting element is attached to the component via an anchoring means such as a screw or the like. The anchoring means may be retained in an area in the connecting element, for example via a thread or a resin, which is subsequently introduced.
These two steps can already be done in the factory or factory. This allows a saving of time and independence from the weather conditions. These components can also be prepared in series and also in advance for the bearing.

In step 3, as described in step c) of claim 1, the component will be transported by means of, for example, a chain-type crane suspended on one or more connecting elements. This or these fasteners are provided with holes for hooking, which facilitate the attack and in this way the Capture connection element together with the components.

This not only facilitates, for example, the transport on a truck, but also facilitates the movement at the construction site.

In step 4, as described in step d) of claim 1, connecting plates for the positioning and attachment of the wood panel or the carrier are provided with another similar wooden panel via the connecting element. Furthermore, connecting plates can be provided which are positioned and rigidly connected to the substrate, to which the connecting element is fastened in such a way that an easy, secure and accurate fastening to the substrate is produced, or a component could already have been positioned and fastened. With this first component, the second is connected via a connection plate as described above. These connections form a node. In the subsequent steps, a number of other components can be connected to make the construction. Nodes can be created where more than one fastener is attached. In a preferred embodiment, these nodes can be connected directly to one another in such a way that a supporting structure is produced.
However, this connection can also take place only in a single direction, for example only a connection of superimposed nodes in the vertical direction. Hereinafter, a preferred method according to the invention will be described with reference to the drawings and a connecting element for carrying out the method in a non-limiting manner. Show it

The method according to the invention comprises the following steps. The first step concerns the preparation of the wooden board or the support made of wood 1. This first step consists of a machining of the component and can additionally in a positioning of the component. 1 consist. The processing consists in the preparation of one or more surfaces. In the case of the wood panel, it consists in the removal of a corner and preferably further processing to provide a connection or personalization of the wood panel. Alternatively, the component is a carrier in which material is removed at one or both ends.

In step 2a, the connecting element 2 is positioned. This positioning takes place on a surface machined in step 1, ie on the cut-off corner of the panel or inserted in a recess made by ablation of material on the support.

In step 2b, the connecting element 2 is fastened to the component 1. The attachment takes place via anchoring means 3.

At step 3, the component 1 is moved / displaced, for example, from the factory / workshop on a truck to be brought to the construction site. The movement takes place via a hooking on the connecting element 2. This hooking takes place in holes 4, which are wide in the connecting element 2. A rope 5 or the like is connected to the connecting element 2 or to a plurality of connecting elements 2. In this way, a rapid and accurate adjustment of the component 1 is ensured.

In step 4, a connection plate 6 prepared. These agents are used with other like wooden panels or girders connected and possibly additionally, for example, in the ground directly during the casting of the same.

In step 5, the component is positioned and fastened to the connection plate already provided in the previous step.

In step 6, one or more further of the same wood panels or beams are positioned in connection with the first component 1. The connection is made via the connecting elements and the connecting plates, which connect a plurality of connecting elements 2, wherein this connection forms a node in each case. These nodes 7 can be connected to each other. For example, all superimposed nodes perpendicular, such that a structure is produced, which is directly connected to the ground.
These nodes 7 can be connected to each other, for example by means of threaded rods 8, which are screwed to the connecting plate 6.
In FIG. 9 and 11 Embodiments of several components 1, 1a, 1b are shown, which are connected to each other and, for example, in the FIG. 1 are means for receiving additional components available.
In a preferred embodiment for the purpose of manufacturing, for example, a connection system with exterior elements, the connection element 2 may be provided with threaded rods within the body of the connection itself. These threaded rods are vertical to the body of the connection itself and arranged in the plane of the panel to which the connection element is connected.

In Step 1, in the case of a carrier, material is removed at one or both ends of the carrier. In the formed recess, a connecting element is introduced and fixed.

During step 7 and subsequent steps, the carrier is attached to another carrier at the end. This connection takes place, for example, by sinking. This means that it takes place on a section which is equal to or smaller than the carrier.
In this way, there are no external parts facing the carrier to make the connection of two or more carriers.

The inventive method can also for the production of other makeshift structures such as Example scaffolding for assembly or even the completion can be used.
By fixing the fasteners 2 attached to components 1, a stable structure can be produced which allows a construction with certainty of the end structure. The method by means of the connection plates allows the exact positioning of the panels, which are forced into the exact position of the panels and are also held in the correct position by the panels themselves during the temporary assembly step.
The method allows the assembly of wood panels or beams made of wood, with a precise distance between adjacent like components
is taken into account. This room can be filled with material, for example sound-absorbing material sound-absorbing material or, for example, material for thermal insulation and / or for the air sealing of the building.

The method allows the connection of wood panels or beams made of wood which are connected by means of connecting elements 2, where the connected components 1 are arranged arbitrarily in space; in particular, the panels can be connected perpendicular to each other, or the panels can be connected to other panels which are cut off at any one corner. The method allows a precise and reliable method of calculation of the structure, the wood panels or supports fixed according to the method via the fasteners can be determined via an automatic calculation procedure by means of a electronic calculator, since the resistance and stiffness values of the connecting elements and the components are known. In the automatic calculation procedure, the structure obtained by the method is outlined by a series of nodes 7 connecting the components, the resistance and rigidity of which nodes are known, since the characteristics of the connection elements 2 used are known, the calculation procedure for the design is the structure to be produced according to the method.
To ensure greater stability between the connection nodes 7, they can be connected via rods 8, as well as in FIG. 14 shown. In this way, a support structure is formed between the individual nodes 7. The method according to the invention also allows the production of connection structures that form Raunknoten. This allows the production of nodes that also connect the outer structure with ceiling elements, thus ensuring a faster assembly of a node 7 for connections in any direction and a simpler design, since the number of nodes 7 is limited. Moreover, these nodes can be connected to rods 8 which in this way create a spatial supporting structure. The FIG. 13 shows a connection via two connecting elements 2, which are fastened via anchoring means 3 each have a component 1. The two connecting elements 2 are connected via a connecting plate 6.

The FIG. 15 a component 1 is shown, which is connected by means of the connecting element 2 and a connecting plate 6 to the ground.

FIG. 16 shows a series of components which are connected to each other and to the ground by means of connecting elements 2 and connecting plates 6.

FIGS. 17 to 22 In particular, in these embodiments, the connecting element is also arranged on an outer surface of the component 1 or extends within the component 1. The anchoring means 3 are laterally introduced in the component. In one embodiment, these anchoring means may also be a resin which is introduced to anchor the connecting element 2, as for example in FIG FIG. 22 shown where the resin is indicated by the reference numeral 3.

In a preferred embodiment, not shown, a space structure may be fabricated around a node 7. For example, the outer wall and a ceiling that depart from one and the same node. The components extend from the node in an upward, downward and in a direction perpendicular to the first two components direction.

In order to facilitate the arrangement and the checking of the positions of the connecting elements and / or of the respective components in the connecting elements, electronic means may be provided, for example RFID Chips that allow a check of the position of a component or a connection even after installation. For example, even in the case where the completion has already been done.

These electronic means can also be used to check the position of nodes and components in a non-invasive manner. This may be required, for example, after an earthquake or earthmoving.

The information about the connection element may be present in the electronic means.

In a further embodiment, the component 1,1a, 1b is a framed wooden component, which is understood as a non-solid panel, not a multilayer panel, but a panel formed by a lightweight frame structure (post-horizontal elements and sometimes counter-elements ) on which braced panels of different material are nailed or scored or glued.
