The following documents are incorporated herein by reference as if fully set forth: German Patent Application No. 102013016518.0, filed Oct. 7, 2013.
The invention relates to a three-dimensional structure which is made substantially from panel-shaped material blanks, wherein adjacent material blanks are or can be each connected to one another by mutually opposing sides.
From EP 2 398 972 B1 a method is already known which is intended to produce a three-dimensional structure of the type mentioned at the beginning, wherein this structure is made substantially from panel-shaped material blanks which are cut in sections from at least one material web and are then connected to one another in the form of the structure. The method of manufacture which is already known provides that the structure is divided in a first calculation or mental step into panel sections, wherein by way of example each wall or roof surface lying in one section can form one panel section. The individual panel sections are then in a following mental or calculation step each segmented into panel section parts orientated in the longitudinal or transverse direction of the panel section in order to then place the partition lines of the panel section parts into the connection zone. In a following calculation or mental step the panel section parts of at least one panel section which are to be made from the same structural or work material are placed on a material web which is then cut correspondingly into the panel section parts. The panel section parts of one panel section singled out in this way from the at least one material web can then be connected to one another to form the panel section in order in a following work step to connect the panel sections in the three-dimensional structure at the desired installation site. By the method of manufacture already known it is possible to set up quickly and with low expense a structure which is intended by way of example as a residential or office building, wherein this structure can be intended both for permanent and also for temporary use.
In order additionally to accelerate and simplify the erection of a three-dimensional structure of this kind, the objective lies in particular in providing a structure of the type mentioned at the beginning in which the connection of the panel section parts of one panel section can be simplified and/or accelerated and can also where applicable be carried out quickly and simply at the installation site.
The solution according to the invention to meeting this objective provides in the case of a three-dimensional structure of the type mentioned at the beginning in particular that at least two material blanks which adjoin one another along their opposing narrow sides can be detachably connected to one another without glue by at least one connection fitment which holds together the mutually adjoining narrow sides of the material blanks by at least one screw connection.
The three-dimensional structure according to the invention is made substantially from panel-shaped material blanks which can be connected to one another into one panel section, which panel sections then each form a wall or roof surface of the structure. At least two material blanks which adjoin one another along opposing narrow sides are connected to one another without glue by at least one connection fitment, which at least one connection fitment holds the mutually adjoining narrow sides of the wall sections detachably together without glue by at least one screw connection. The at least one screw connection provided on the mutually adjoining narrow sides of at least two material blanks enables the quick and easy connection of these material blanks where applicable even at the installation site. Since at least two adjoining material blanks can also be connected at the installation site into the panel section forming a wall or roof surface of the structure according to the invention, the building can also be sized with comparatively large dimensions, because the material blanks forming one panel section are also to be transported to the installation site separately from one another. Since the screw connection of the at least one connection fitment guarantees a connection of the material blanks which can also be released again where required, the structure according to the invention can also be dismantled again when necessary in order to be set up again at another site.
A preferred embodiment according to the invention thereby proposes that at least one aperture is provided on the flat side in each of the mutually adjacent material blanks each at a distance from the narrow side intended for contact. An anchor element can be inserted into each aperture. Each connection fitment has at least one threaded rod or a threaded shaft which braces against one another the mutually associated anchor elements of a connection fitment in the apertures of adjacent material blanks. The at least one threaded rod or threaded shaft of each one connection fitment thereby passes through mutually aligned through openings in the material blanks as well as in at least one of the anchor elements. Since the at least one threaded rod or threaded shaft passes through the mutually aligned through openings in the material blanks, the accurately aligned position of the adjacent material blanks in the region of their mutually adjoining narrow sides is ensured.
A preferred embodiment according to the invention provides that the at least one threaded rod or threaded shaft of the at least one connection fitment projects with at least one free shaft or rod end above the thread opening of at least one anchor element and that a clamping nut which is arranged so that it can engage rotationally in the opening can be or is screwed onto this at least one free shaft or rod end. By turning the clamping nut which is screwed onto the free shaft or rod end, the anchor elements of the adjacent material blanks which are connected to one another by the threaded rod or threaded shaft can be braced against one another.
It is possible that the threaded rod or threaded shaft of the at least one connection fitment projects by its two free shaft or rod ends over the anchor elements which are arranged on both sides. An embodiment according to the invention which is particularly easy to handle proposes however that the threaded rod or threaded shaft is held secured against rotation on the adjoining anchor element by its end region which faces away from the free shaft or rod end. The threaded rod or threaded shaft is thus itself secured in a rotationally secured position when the clamping nut which is screwed onto it is tightened up or released again.
In order to be able to work the fastening points required for the connection fitment easily into the material blanks, it is advantageous if the at least one aperture provided in each adjacent material blank has a circular or rectangular opening cross-section.
It is thereby advantageous if an anchor element, configured as a half-cylinder, can be inserted into each aperture having a circular opening cross-section.
On the other hand, in the case of an aperture which has a rectangular opening cross-section, a box-shaped anchor element can be used.
In order to be able to use the structure according to the invention advantageously as a residential or office building, and in order to configure the inside of this structure to be as wind-tight as possible, it is expedient if the joint arranged between the mutually adjoining narrow sides of at least two adjacent material blanks is sealed by at least one joint sealing strip.
In order to configure this joint so as to be reliably wind-tight it is advantageous if the joint which is arranged between the mutually adjoining narrow sides of at least two adjacent material blanks is sealed by at least two joint sealing strips and if the through openings provided in the material blanks open in the narrow side partial area which is arranged between the at least two joint sealing strips.
Further developments according to the invention are apparent from the claims in conjunction with the drawing as well as the description of the figures. The invention will now be described below in further detail with reference to preferred embodiments.
In the figures:
The opposing narrow sides of the material blanks 3, 4, 5 which adjoin one another in pairs are thereby detachably connected to one another without glue by at least one connection fitment 6 which holds together the mutually adjoining narrow sides of the material blanks 3, 4, 5 each by at least one screw connection. The at least one screw connection provided on the mutually adjoining narrow sides of at least two material blanks 3, 4, 5 enables the quick and easy connection of these material blanks 3, 4, 5 of the structure 1 where applicable even at the installation site. Since at least two adjacent material blanks 3, 4, 5 can be connected even at the installation site into the panel section which forms a wall or roof surface of the structure 1, the building can also be sized with comparatively large dimensions because the material blanks 3, 4, 5 which form one panel section can also be transported separately from one another to the installation site. Since the screw connection of the at least one connection fitment 6 ensures a connection of the material blanks 3, 4, 5 which can also be released when necessary, the structure 1 illustrated here can also be dismantled again when required in order to be erected anew at a different site.

The threaded rod 13 can thereby be turned tightly into a threaded blind hole in the anchor element 9, 11 or can be glued, welded, soldered or fixedly connected in another way with the anchor element 9, 11.
Whereas the apertures 7 provided in the material blanks 3, 4, 5 of the structure 1 illustrated in
