Description

Method for the Manufacture of a Three-Dimensional Structural Body The invention relates to a method for the manufacture of a three-dimensional structural body that is manufactured substantially from plate-shaped material blanks, which material blanks are cut to size in sections from at least one material strand and are subsequently connected to each other in the form of the structural body.
The structural form of massive wood construction is increasingly used in wood construction work. In this type of construction walls or ceilings are manufactured from solid massive wooden elements or elements of wooden material. An advantage of this construction type is, among other things, the fact that walls or ceilings can be prefabricated during the manufacturing work as a finished, joined wall or ceiling element. The massive wooden elements or elements of wooden material are first manufactured from several layers of boards or of plates by, in particular, crosswise adhering. These massive block panels are cut to size in further work steps in accordance with the instructions of the plan to massive wooden elements or elements of wooden material.
The conventional manufacturing method is especially disadvantageous during the insertion of openings, e.g., for windows or doors, since in this instance the openings are produced by sawing them out of the completely planar element.
A continuous process for the manufacture of modular wall elements and ceiling elements as are needed, for example, for establishing a cooling chamber was previously described in EP 1 992 758 A2. The previously known method provides cutting to size the wall elements and ceiling elements needed for the manufacture of a three-dimensional structural body as material blanks from an endless material strand in order to connect to each other the material blanks used as wall elements and ceiling elements at their sides adjacent to each other in the corner areas of the structural body with the aid of connection elements. Since no planar door openings or window openings are let into the wall elements and ceiling elements, the walls and ceilings of the structure to be produced can be manufactured from continuous, planar wall elements or ceiling elements and also the problem of material waste does not occur in the method previously known from EP 1 992 758 A2.
2 Different modular separating wall systems are already known from WO
2006/039761 Al and DE 198 46 599 Al in which systems each separating wall is manufactured from an appropriate number of wall panels, whereby the wall panels are connected to each other on their adjacent narrow sides by a fold connection or a groove and spring connection. Since even these previously known separating wall systems do not need any planar door openings and window openings, the problem of material waste is also not present in these separating wall systems.
There is therefore the problem of creating a manufacturing method of the initially cited type that is distinguished by a substantially reduced consumption of material.
According to an aspect of the present invention, there is provided a method for the manufacture of a three-dimensional structural body that is manufactured substantially from plate-shaped material blanks, which material blanks are cut to size in sections from at least one material strand and are subsequently connected to each other in the form of the structural body, wherein the structural body is subdivided into plate planes that for their part, are segmented into plate plane sections oriented in the longitudinal or the transverse direction of the plate planes, the dividing lines of the plate plane sections of at least one plate plane comprising at least one planar plate plane opening are placed in the connection area between plate plane sections oriented in the longitudinal direction and adjacent plate plane sections oriented in the transverse direction, which plate plane sections surround a planar plate plane opening there, the plate plane sections comprising the same structural material or work material are aligned on each other in such a manner that the plate plane sections of at least one plate plane can be projected onto at least one material strand, and this at least one material strand is subsequently cut to size to the plate plane sections before the plate plane sections of a plate plane that are individualized in such a manner from the at least one material strand are connected to each other to form the plate plane.
The method in accordance with some embodiments of the invention provides that the structural body is subdivided in a first calculating step or intellectual step into plate planes, whereby, for example, each wall surface or ceiling surface located in a plane can form a plate
3 plane. The individual plate planes are subsequently segmented in a following intellectual step or calculating step into plate plane sections oriented in the longitudinal direction or the transverse direction of the plate plane in order to subsequently place the dividing lines of the plate plane sections in the connecting area. In a following calculating or intellectual step the plate plane sections of at least one plate plane section that are to be manufactured from the same construction material or work material are placed on a material strand that is subsequently cut to size in accordance with the plate plane sections. The plate plane sections of a plate plane individualized in this manner from the at least one material-material strand can subsequently be connected to each other to the plate plane in order to connect the plate planes to the three-dimensional structural body at the desired site of use in a following work step.
The construction materials or work materials used for cutting the plate plane sections to size can differ in the material, in the material thickness and/or in the surface coating or in any other suitable feature. In the method in accordance with some embodiments, the plate planes serving as wall- or ceiling element are prefabricated from several plate plane sections taking into consideration their planar openings. The plate plane sections prefabricated in this manner can be assembled in a special joining method to the plate plane serving, for example, as a wall- or ceiling element. Since the planar window or door openings do not have to be manufactured in the method in accordance with the invention by being sawed out of the completely planar wall element or ceiling element, the method in accordance with the invention is distinguished by a significant saving of material.
In order to be able to use even especially loadable structural materials or work materials in especially stressed partial areas of the three-dimensional structural body it is advantageous if the plate plane sections of at least one plate plane of the structural body are cut to size from at least two material strands consisting of different construction materials.
The plate plane sections cut to size from the material strand can be connected in an especially simple and permanent manner to the plate plane serving, for example as wall element or ceiling element if the plate plane sections are provided with a joining profile at least in the area of their dividing lines.
4 In order that even plate plane sections can be connected to each other that do not necessarily have to have parallel plate edges, it is advantageous if the clamping force required for fixing the plate plane sections of a plate plane is applied vertically to the plate plane and/or if the acting direction of the amount of pressure applied required for connecting the plate plane sections of a plate plane takes place parallel to the plate plane.
A preferred embodiment in accordance with the invention provides that the plate plane sections are connected to each other by a suitable selection of positive fit, non-positive fit and same-substance fit. Whereas the positive fit can be brought about, for example, by a wedge dovetailing in the case of a gluing profile and whereas the non-positive fit takes place by the force applied during the pressing together or by the force acting on the wedge plane of the dovetailing, the same-substance fit can be produced, for example, by gluing or welding. If the joints between the plate plane sections are connected to each other by positive and/or same-substance connection methods, even a permanently joint-tight connection can be readily produced.
The joints between the plate plane sections can be differently formed, e.g., straight or curved, with or without support projection. In order to achieve an improved diminution of load in the area of the connection joint, a trapezoidal joint design is also possible. It is therefore advantageous if the dividing lines between the plate plane sections to be connected to each other are constructed from a suitable selection of straight, curved or trapezoidal joints.
It is advantageous if the plate plane sections are cut to size in a cutting separating method.
Here, the separating of the material strand previously produced in an endless manner takes place by a cutting procedure running at a right angle to and/or at a relative angle to the plate planes. The separating can take place, for example, by sawing or milling. For door or window cutaway portions braces can be introduced to secure the cutaway portions of the plate plane during the manufacturing process.
Other features of some embodiments of the invention result from the following description of an exemplary embodiment in accordance with the invention in combination with the drawings. The present invention will be explained in detail using the following exemplary embodiments.
The individual method steps of the manufacturing method of examples of embodiments of the invention will be described in detail using figures 1 to 8, in which:

Figure 5 shows an example of plate plane sections having a joining profile according to an embodiment of the present invention;
Figure 6 shows plate plane sections having a joining profile according to another embodiment 1 5 of the present invention;
Figure 7 shows an example of plate planes being connected together under pressure; and Figure 8 shows an example of an arrangement of plate plane sections joined at appropriate positions in a material strand.
The method presented here is provided for manufacturing a three-dimensional structural body 1. The structural body 1 is shown in figure 1 by way of example in the form of a rough construction. The structural body 1 is manufactured substantially from plate-shaped material blanks that are cut to size in sections from at least one material strand and subsequently connected to each other in the form of the structural body 1.
6 It can be recognized in figure 1 that the structural body 1 is subdivided in the first calculating step or intellectual step into plate planes A, B, C, D, E and F, whereby, for example, each wall surface or ceiling surface located in a plane can form a plate plane A, B, C, D, E or F.
These plate planes, lined up adjacent to each other in figure 2 in a projected strand are subsequently segmented - as will become clear from figure 3 - in plate plane sections 2 oriented in the longitudinal direction or the transverse direction of the plate planes.
It is indicated in figure 4 that the plate plane sections 2 consisting of the same structural material or work material are aligned adjacent to each other in another calculating step or intellectual step in such a manner that the plate plane sections can be projected on at least one material strand.
The plate planes A, B, C, D, E and F provided, for example, as wall- or ceiling elements are understood to be assembled structural parts, whereby in the assembly of the plate plane sections 2 the formation of planar door or window openings can be considered to be material-saving. Each plate element section 2 can be manufactured under the aspect of material optimization by the joining together of the plate plane sections 2 of a plate plane provided as a total structural part. Thus, a considerable saving of material can be achieved by the manufacturing method presented here, which saving essentially takes place by the waste-saving (pre) segmentation of each plate plane A, B, C, D, E and F into plate plane sections 2.
The dimensioning of the plate plane sections 2 takes place by the preceding cutting to size of standardized raw elements and/or by a measurement-related production of the plate plane sections 2. The plate planes A, B, C, D, E and F can have a homogeneous or an inhomogeneous composition, whereby the plate plane sections 2 of at least one plate plane of the structural body 1 can also be cut to size from at least two material strands consisting of different construction materials. The method shown here can be used in the working of all plate-shaped construction materials or work materials. However, a preferred usage of the method shown consists in that the plate-shaped construction materials or work materials consist of wood or of a wooden work material. The plate plane sections 2 can therefore be
7 manufactured as massive wooden elements or can also be produced, for example, from OSB, FPY, or a combination of these materials.
The construction materials or work materials used for cutting the plate plane sections 2 to size can differ in material, and the material thickness and/or in the surface coating or in any other suitable feature. Therefore, the plate plane sections 2 to be assembled to a total element A, B, C, D, E or F do not have to be manufactured from the same material or construction material.
As soon as the plate plane sections 2 of at least one plate plane that are to be manufactured from the same construction material or work material have been projected onto the material strand consisting of the desired material the at least one material strand can subsequently be cut to size to the plate plane sections 2 before the plate plane sections of a plate plane A, B, C, D, E and F individualized in such a manner from the at least one material strand is are connected to each other to the plate plane.
The plate planes broken down during the preparation of the work into the necessary plate plane sections 2 and serving later, for example, as wall element or ceiling element are manufactured by the aid of optimized cutting-to-size systems from prefabricated panels (cf. figure 3).
Figures 5 and 6 indicate that the plate plane sections 3 can be provided in another work step with a joining profile 3 that facilitates the subsequent joining together of the plate plane sections 2 to an endless strand.
The manufacture of the joining profile can take place in a work process connected in beforehand by a cutting method, whereby for example, a work procedure with the work steps "profile milling", "gluing", "transport", "gluing", "clamping", "pressing" can be selected.
The joining together of the plate plane sections 2 to a strand takes place in a subsequent working step. It is also possible that the cutting manufacture of the joining profile precedes the subsequent joining process in a clamping procedure so that the work procedure also could comprise the work steps "clamping (horizontal-vertical)", "milling", "gluing", "pressing".
Another possibility consists in that the joining profile is provided in the preceding
8 manufacturing process of the particular plate plane section, for example, by gluing in a profile fitting strip.
It is clear from a comparison of the figures 5 and 6 that the joining profile does not necessarily have to run over the entire structural part but rather it can be sufficient that the plate plane sections 2 are provided only in the area of their dividing lines with a joining profile. As a result of the particularity of an insertable tool, joining profiles can also be introduced only into the cross-sectional areas of the structural parts necessary for connecting the plate plane sections 2.
It is indicated in figure 7 that the amount of pressure required during the gluing of the plate plane sections 2 to the plate plane is applied vertically to the plate plane.
This makes it possible to connect plate plane sections 2 to plate edges that are not necessarily parallel.
The connecting of the individual plate plane sections 2 can take place by a non-positive fit, a positive fit and/or a same-substance fit. The positive fit and/or same-substance fit connection of the joints present between the plate plane sections 2 makes possible a permanent, joint-tight connection.
A same-substance connection can take place by gluing or welding. For a positive fit connection a wedge dovetailing or a gluing profile can be used. A non-positive connection takes place by the pressure force required during the pressing together of the structural elements or by the force acting on the wedge plane of the dovetailing.
In some embodiments, the manufacture of a plate plane serving, for example, as a wall element or ceiling element takes place taking into consideration conduits or recesses that are introduced horizontally as well as vertically into the plate planes and that can be used, for example, as installation conduits.
It is clear from figure 1 that the joints between the plate plane sections 2 adjacent to each other can be differently formed, for example, straight, curved or with or without support projection. It is shown in figure 1 in the area of the window openings that the joint
9 constructions can also be designed to be trapezoidal in order to achieve an improved diminution of load in the area of the connecting joint.
The manufacture of the same-substance connection takes place with the aid of adhesives or other suitable joining agents whose connection quality takes place under the availability of pressure, heat and/or time. The connection between the plate plane sections 2 can also take place by pressing or glue with or without the supply of heat. Other connections such as, for example, double butt strap joints or dowel connections are also possible.
The geometry of the openings provided in the plate planes, for example, as window or door opening do not have to necessarily be at a right angle.
It is indicated in figure 7 that the total pressing force required to connect the plate plane sections 2 can be achieved by partially adjustable partial pressures that are to be adapted to the amounts of pressure required for the cross section of the plate plane sections 2.
It is possible by the manufacturing method shown here to manufacture joint-tight angular connections or wall ceiling connections. Such joint-tight angular connections are advantageous, for example, in the areas of "wall-to-wall", "ceiling-to-wall"
or "ceiling-to-roof'. The plate plane sections can be connected to each other, for example, by joining them together with the aid of special angle pieces (e.g., T-connection).
After the plate plane sections 2 have been projected onto the material strands associated with them the separation of the element strand produced at first as an endless strand takes place in a cutting procedure running at a right angle and/or at a relative angle to the plate plane. In the case of roof plates the cutting procedure can become necessary in the cutting procedure arranged at an angle relative to the plate plane. The separation can take place by sawing or milling. For door or window cutaway portions braces can also be introduced to secure the appropriate structural parts during the manufacturing process. Such braces are intended to prevent the "folding together" of the structural parts.
Figure 8 shows that the plate plane sections, that are optionally provided with a suitable joining profile corresponding, for example, to the intended use, are joined together at the appropriate position to an endless strand in order that the strand can be subsequently separated into the required wall elements and/or ceiling elements of the plate planes and cut to length.
The application range of the manufacturing method presented here goes beyond the use as a constructive or non-constructive wall element or ceiling element in the construction area. This 5 application range also comprises residential construction and industry construction. Further, application ranges in the construction area are, e.g., bridge construction.
The plate-shaped construction elements manufactured with the method in accordance with some embodiments of the invention can be used in building construction but also as a façade system, sound-proofing elements or the like. Other applications in modular construction are conceivable, for
10 example, caravan construction, internal ship construction, measuring stand construction, weekend garden houses, modular buildings (school containers, residential containers or work containers).
