Description

field of invention

The invention relates to a variable container system for creating cuboid room cells arranged next to and one on top of the other, which can be used for living or working.

Background of the Invention

Containers of the type mentioned are used wherever fixed, immobile facilities are regarded as unprofitable or uneconomical. Containers of the aforementioned type are intended in particular to be able to provide habitable space quickly and flexibly, for example for use as an office, sick room, operating theater and the like.

Usually, such containers are cuboid, prefabricated room cells that are stacked next to each other and assembled to form a structure on site. In the patent application WO 2010/083798 A1 a container system is proposed which enables quick and variable assembly and disassembly. U.S. 2002/193046 A1 discloses another container system.

Summary of the Invention

The present invention was developed in light of the prior art described above. The object of the invention is to further improve the variable container system known from the prior art for creating room cells arranged next to and/or on top of one another and, in particular, to simplify the construction and to increase the structural stability and mechanical load-bearing capacity.

This object is achieved in that a room cell comprises: a) a floor element serving as the lower base with a total of four saddle elements arranged at the corners with inclined guide surfaces for Placement of two end wall elements, b) a roof element serving as an upper cover with a total of four saddle elements arranged at the corners with inclined guide surfaces for placing on the two end wall elements, c) two end wall elements each with two inclined lower corner guides for placing on the saddle elements of the floor element and each with two inclined upper corner guides for placing the saddle elements of the roof element on the bulkhead element, wherein d) each guide surface of the floor element is inclined downwards in the direction of the two saddle elements arranged opposite one another; and e) each guide surface of the roof element is inclined in an ascending manner in the direction of the two oppositely arranged saddle elements; and f) the corner guides of the end wall elements each have complementary inclinations to said guide surfaces. The guides of the floor elements and the end wall elements are therefore complementary to one another with regard to their dimensions, shape and inclination. A floor element has a total of four saddle elements, namely two each for a front end wall element and two each for an opposite rear end wall element. The direction of inclination of the saddle elements is selected so that force is exerted on a front wall element by its weight when it is placed on the floor element, specifically a force component acts in the direction of the middle of the front wall element. The other force component perpendicular thereto acts in the direction of the opposite end wall element. Due to the inclined guide surfaces of the saddle elements, the end wall element is thus advantageously centered on the floor element when it is placed on the floor element. Thus, the bulkhead element slides into the intended position due to the force of gravity. As a result, the opposing end wall elements of a room cell are aligned with one another. The bulkhead element is pressed inwards by the other force component. The bevelled inclined guide surfaces at the top of the end wall elements allow the roof element to also slide into the centered position when it is placed on the end wall elements. This ensures that further storeys can be positioned. The nested elements are thus wedged on the saddle elements and are then connected to each other in a non-slip manner. This creates a self-aligning and self-supporting frame of a room cell.

Advantageous refinements of the invention with non-limiting additional features are described below.

The guide surfaces of the saddle elements can each have a convex or concave curvature and the corner guides of the end wall elements can each have a complementary concave or convex curvature. This advantageously increases the guide surfaces. A full-surface load-bearing connection is created on the saddle elements in the manner of a ball joint, which ensures even more precise positioning due to the spherical curvature, even with possible production-related tolerances of the components. The bulges can either be formed directly onto the saddle elements and corner guides or be designed as correspondingly shaped saddle plates and/or support plates which are placed on the saddle elements and are fastened to the corner guides.

In order to fasten the end wall elements to the floor element and/or the roof element, the saddle elements can each have a truncated cone with an internal thread and the corner guides of the end wall elements can each have a complementary hollow truncated cone that can be placed thereon, with a truncated cone and a hollow truncated cone each being closed by a screw that can be screwed into the internal thread are connectable.

The bulkhead members may be dismountable to further facilitate transportation and maintenance. They can also be adjustable in width to ensure better adjustment.

The vertical beams can have lower and upper brackets with elongated holes, with which the horizontal crossbeams can be screwed, in order to enable the width of the end wall elements to be adjusted.

As an alternative or in addition, the end wall elements can be connected to the floor element and the roof element by pulling devices. As a result, the components are additionally braced and firmly connected to one another.

Each pulling device is prestressed by two holding elements, with the first holding element for the lower pulling device being fastened in the middle edge area on the inside of a front wall element and the second holding element being fastened on the upper side of the floor element, and with the first holding element also being fastened in the middle edge area for the upper pulling device the inside of an end wall element and the second retaining element is attached to the underside of the roof element, so that an imaginary right-angled triangle is spanned by the two retaining elements and the pulling device.

A traction device can comprise a steel cable. The traction device preferably comprises a traction rod. The advantage is that a tie rod can absorb not only tensile but also compressive forces, so that the rigidity of a space cell formed in this way is significantly improved.

The traction device is designed in such a way that the tension can be adjusted. As a result, the tension or prestress and thus the angle between the floor element or roof element and the end wall elements can be precisely adjusted. For example, a tie rod can have a thread and a socket that accommodates the thread, so that rotating the tie rod changes its length and thus the preload.

Two room cells fastened next to each other on the long sides can be clamped together by cross-shaped tension devices and thus coupled.

Detailed Description of Preferred Embodiments

In the following, preferred embodiments of the invention are described in detail with reference to the drawings, further advantageous features being evident from the figures of the drawing.

figure 1 shows a perspective view of the components of a room cell 1. For reasons of clarity, components are "floating", ie shown slightly outside of their plugged-in position. A cell 1 of the container system comprises a lower floor element 10, a front 30 and a rear end wall element 30 and an upper roof element 20. The roof element 20 is essentially identical to the floor element 10, ie it is the same element without a structural difference exists. A floor element 10 thus becomes a roof element 20 within a container system by being fastened "upside down", ie with its underside facing upwards, on the end wall elements 30 . The two end wall elements 30 are also structurally identical, so that the room cell 1 shown is essentially composed of only three different load-bearing components 10, 20, 30.

The floor 10, end wall 30 and roof element 20 have an essentially rectangular basic shape, resulting in a cuboid shape for the room cell 1 overall. The components mentioned have an outer, essentially rectangular frame made of steel or aluminum. The floor 10 and roof element 20 each have two longitudinal struts 13, 23 and outer and middle stiffening cross struts 14, 24. A front wall element 30 comprises two beams 33 which are arranged vertically in relation to the floor element 10 and are spaced apart by a lower and an upper horizontally extending cross beam 34 and are connected to one another by welding. The frame structure shown results in rectangular openings for the front 30 and for the floor 10 and roof element 30 as well as on the sides. The interior angles of all openings are always 90 degrees. In the opening of the front end wall 30 a plate 40 of suitable material with windows 41 is fastened. The side walls are supported by several non-structural panels 42 formed and roof element 20 has a cover 43 on. When the rectangular openings of the floor element 10 are closed by panels (not shown), the floor element 10 forms a walkable floor. In this way, a closed room cell 1 can be created.

The underside of the floor element 10 either rests directly on a horizontal floor surface or, in the case of a multi-storey container system, is fastened to the identically constructed roof element 20, as a result of which a floor element (not shown) is formed. The two components 10, 20 are attached to one another by means of a screw connection.

The floor element 10 serves as a horizontal base for the end wall elements 30. To place the two end wall elements 30, a saddle element 11 with an inclined guide surface 12 is provided at the four corners of the floor element 10 at the top. The guide surfaces 12 are bevelled and arranged in such a way that their slope decreases both in the direction of the outer transverse strut 14 and in the direction of the longitudinal struts 13 . In relation to the floor element 10, the highest point of the guide surfaces 12 is therefore arranged at the outer corner and the lowest point opposite at the inner corner.

The end wall elements 30 have on the underside of the vertical supports 33 downwardly inclined corner guides 31 which are inclined towards the guide surfaces 12 of the saddle elements 11 of the floor element 10 and can thus be placed on them. Due to the inclined guide surfaces 12 of the floor element 10 and the complementarily inclined corner guides 31 of the end wall elements 30, the end wall elements 30 are not only pressed down by their weight but also centered. In addition, they are pressed inwards in the direction of the longitudinal struts 13 up to the stop elements 15 provided for this purpose, so that they assume the desired position.

Since the roof element 20 is essentially structurally identical to the floor element 10, it has four identical saddle elements 21 with inclined guide surfaces 22 at its two corners, but these point downwards, since the roof element 20 turned 180 degrees "upside down". The guide surfaces 22 are used to attach the roof element 20 to the two end wall elements 30 which have complementary upper corner guides 31 . As a result, the roof element 20 is centered in the longitudinal and transverse direction on the two end wall elements 30 solely by its weight.

The components 10, 20, 30 are fastened by means of the tie rods 50, 51.

It is possible to completely pre-assemble the room cells 1 and to transport them as finished room cells 1 and set them up and stack them on site. This option can be advantageous for smaller container systems because the pre-assembly means that it can be set up more quickly and cost-effectively. In the case of medium-sized and large container systems, it is more advantageous to transport the room cells 1 disassembled and to assemble them on site.

figure 2 shows a perspective view of a room cell 1, which consists of the components figure 1 is put together. The bottom floor element 10 serves as the basis for the room cell 1 shown. A front 30 and a rear end wall element 30 are placed on the floor element 10 . One end of the lower tie rods 50 is fastened to the inside of the vertical supports 33 of the end wall elements 30 and the other end to the longitudinal struts 13 of the floor element 10, so that the tie rods 50 each form a right-angled form triangle. On top of the end wall elements 30 is placed an upper roof element 20 which is fastened to the vertical beams 33 of the end wall element 30 by means of upper tie rods 51 in the same way. The overall shape of the room cell 1 is a cuboid.

figure 3 shows a perspective view with four floor elements 10 and two inner walls 44. To a container system of four room cells 1 (see figure 2 ) to build up, the four floor elements 10 are arranged side by side as shown. Two inner walls of the container system are shown above the four floor elements 10 . Because of For clarity, an inner wall 44 is shown "floating", that is, slightly above its intended position.

A single inner wall 44 is formed from two structurally identical end wall elements 30 fastened to one another. A total of four end wall elements 30 are shown. A multi-storey container system with many room cells 10 arranged next to and above one another can therefore be constructed from only three components, namely the floor or roof element 10, 20 and the front wall element 30.

In this case, two end wall elements 30 are fastened to one another in such a way that their beveled upper and lower corner guides 31 form a common, downward-pointing 39 and a common, upward-pointing groove 38, which are each approximately V-shaped in section. In each case two floor elements 10 are arranged end to end, so that in each case two saddle elements 11 lying against one another form a joint bung 19 with their inclined guide surfaces 12 which is complementary to the lower groove 39 formed by two end wall elements 30 . The two end wall elements 30, which together form an inner wall 44, can be pushed onto the bung 19 with the groove 39, as a result of which two floor elements 10 are firmly connected to one another by the clamping effect of the groove 39. Since the floor elements 10 are identical to the roof elements 20, their saddle elements 21 form the same tongue and groove (not shown), which is also complementary to the upper groove 38 formed by two end wall elements 30 and through the two roof elements 20 by the clamping effect of the groove 38 can be connected to each other in the same way.

When assembling a room cell 1, the end wall elements 30 or inner walls 44 are secured after they have been placed on the floor elements 10 by being fastened to the floor elements 10 with the lower tie rods 50 immediately after being pushed on. This serves first of all for occupational safety, since it prevents the end wall elements 30 from tipping over. The tie rods 50 are designed in such a way that their tension can be adjusted. Therefore, during the further build-up, the tensile stress set and the position of the end wall elements 30 are adjusted. The tie rods 50, 51 also improve the stability of a room cell considerably, since they can absorb and dissipate not only tensile but also compressive forces.

The attachment of components of the container system is always to be understood as a detachable attachment or plug-in connection, since the container system can be used as required and quickly set up and dismantled again.

figure 4 shows a perspective view of a container system with four room cells 1. It is shown that a single outer wall is formed from a front wall element 30 and a single inner wall 44 from two front wall elements 30. The roof elements 20 are attached to the front wall elements 30 by means of the upper tie rods 51.

In the case of a multi-storey structure, floor elements 10 of the same construction would be fastened to the roof elements 20 and then end wall elements 30 and roof elements 20 etc.

figure 5 shows a perspective detailed side view of the lower corner area of the room cell 1 figure 1 with components shown "floating" on top of each other. One of the four corners of the floor element 10 is shown with a saddle element 11 for placing the vertical supports 33 of the end wall element 30 . The saddle member 11 is wedge-shaped and has an upper guide surface 12 with a double slope. On the one hand, the guide surface 12 is inclined in direction a to the front cross brace 14 sloping down. On the other hand, the guide surface 12 is inclined in direction b toward the longitudinal strut 13 sloping down. Complementarily inclined corner guides 31 are provided at the upper and lower ends of the vertical beam 33 and can be placed on the saddle elements 11 . The saddle elements 11 center the end wall elements 30 on the cross brace 14 in direction a and also press them in direction b, i.e. in the direction of the longitudinal beams 13 of the floor element, up to the edge of the stop element 15.

In order to compensate for manufacturing tolerances and achieve an even better connection and centering, a saddle plate 16 which is flat on the underside and convexly curved upwards on the upper side is provided, which is fastened to the corner guide 31 or to the support plate 36 . Correspondingly, a support plate 36 is attached to the corner guide 31 and has a complementary concave curvature.

A holding element 52a for fastening the lower pull rod 50 is fastened to the upper side of the longitudinal strut 13 .

figure 6 FIG. 12 shows a perspective front detail view of the components figure 5 . In particular, it is shown that the support plate 36 has a concave curvature on the underside and is flat on the upper side. Furthermore, it is shown that the horizontal crossbeam 34 of the end wall element 30 is designed as an angular U-shaped profile with legs 35 of different lengths and pointing downwards. The U-shaped profile of the cross member 34 thus serves as a guide when it is placed on the cross brace 14.

figure 7 shows a perspective detailed view of the assembled components 10 and 30 from figure 5 . The saddle element 11 is shown with the vertical support 33 placed on it, the saddle plate 16 and the support plate 36 being arranged between the corner guide 31 and the saddle element 11 . The stop 15 limits the movement of the end wall element 30 in direction b (see figure 5 ), ie in the direction of the longitudinal strut 13. The pull rod 50 is attached to the holding element 52a, which in turn is attached to the longitudinal strut 13.

figure 8 shows a perspective detailed view of the assembled components 10 and 30 from figure 6 . The saddle element 11 is shown with the vertical support 33 placed on it, with the saddle plate 16 and the support plate 36 being arranged between its corner guide 31 and the saddle element 11 . It is also shown that the legs 35 encompass the upper area of the cross brace 14 and thus serve as a guide for the cross member 34 .

figure 9 shows a perspective view of a container system with four room cells 1, the front one being shown floating. The floor elements 10 are each fastened to the end wall elements 30 by means of the lower tie rods 50 and the roof elements 20 are each fastened to the end wall elements 30 in a prestressed manner by means of the upper tie rods 51 . The tie rods 50, 51 are fastened by the lower holding elements 52a, the middle holding elements 52b and the upper holding elements 52c (not shown, see FIG figure 11 ). The tie rods 50, 51 of two spatial cells 1 arranged next to one another run parallel to one another. The room cells 1 are connected to one another by screwing.

figure 10 shows a perspective detailed view of a second embodiment of the container system with two room cells 1, 1'. The upper and lower tie rods 50, 51 of the two spatial cells 1 arranged next to one another do not run parallel to one another, but rather cross one another and form an X-shape. The lower pull rod 50, which is attached to the longitudinal strut 13 of the floor element 10 by means of the holding element 52a, is not attached to the end wall element 30, which is placed on this floor element 10, but is attached to the end wall element 30 with the holding element 52b''Fixed, which is placed on the adjacent floor element 10'. The lower pull rod 50' fastened to this same floor element 10' is correspondingly fastened to the end wall element 30, which is placed on the mentioned floor element 10 arranged next to it.

In the same way, the upper tie rod 51, which is attached to the longitudinal strut 23 of the roof element 20, is attached to the end wall element 30', on which the roof element 20' arranged next to it is placed, and the upper tie rod 51', which is attached to the longitudinal strut 23 'of the roof element 20' is attached to the end wall element 30, which is placed on the roof element 20 arranged next to it. The upper tie rods 51, 51' also cross one another and form an X-shape.

As a result, space cells 1, 1' arranged next to one another are additionally fastened to one another crosswise and clamped together.

figure 11 shows a perspective detailed view of the second embodiment with crosswise bracing of the tie rods 50, 50', 51, 51' as in FIG figure 10 from below. In this view, the upper support members 52c are shown.

figure 12 shows a perspective detailed view of a third embodiment. One of the four corners of the floor element 10 is shown with a saddle element 11 for placing the vertical supports 33 of the end wall element 30 . The embodiment shown differs from the embodiments described above, inter alia, by the saddle element 11. To illustrate the function, the same saddle element 11 is shown in FIG figure 12 shown four times next to each other and respectively denoted by the numerals 11a, 11b, 11c and 11d. The saddle member 11 is wedge-shaped and has an upper guide surface 12 with a double slope or bevel, as described above in the other embodiments. However, the surface 12 is not convex but flat. In order to achieve an even better connection and centering when placing the vertical supports 33, a truncated cone 112 with an internal thread 113 is fixed on the surface 12 instead. A locking screw 114 with a matching external thread 115 is provided for the internal thread 113 . A support plate 136 is arranged between the saddle element 11 and the cap screw 114 and can be fastened to the saddle element 11 with the cap screw 114 .

In the case of the saddle element 11b, the support plate 136 and the end screw 114 are shown "floating" one above the other. The support plate 136 has a hollow truncated cone 137 tapered at the bottom, which is complementary to the truncated cone 112 and whose inside diameter is slightly larger than the outside diameter of the truncated cone 112, so that the support plate 136 can be plugged onto the truncated cone 112.

This is shown in the case of the saddle element 11a. The bevel of the surface 12 of the saddle element 11 is compensated by the lower bevel of the hollow truncated cone 137 . The support plate 136 rests on the surface 12 of the saddle member 11a. The cap screw 114 is screwed into its internal thread 113 so that a cap screw ring 117 on the Surface 138 of the hollow truncated cone 137 of the support plate 136 is depressed. Since the diameter of the ring 117 is larger than the surface 138 of the hollow truncated cone 137, the hollow truncated cone 137 or the bearing plate 136 is held securely on the saddle element 11.

In the case of the saddle element 11c, a vertical support 33 of the front wall element 30 is shown floating above it. At the upper and lower end of the vertical support 33 are provided complementary inclined corner guides 31 to the saddle element 11, which can be placed on the saddle elements 11. The support plate 136 is shown attached to the underside of the bracket 33 or corner guide 31, for example by welding. As a result, the entire end wall element 30 is fastened to the saddle element 11 by being screwed together using the end screw 114 . This is shown in the case of the saddle element 11d.

figure 13 shows a perspective detailed view of the third embodiment from the front. It's like in figure 12 one of the four corners of the floor element 10 is shown with a saddle element 11 with a truncated cone 112 for placing the vertical support 33 of the end wall element 30 . In the third embodiment, the two vertical supports 33 and the two horizontal cross supports 34 of the end wall element 30 are not firmly welded to one another, as is the case, for example, in FIG figure 5 is shown, but they are designed to be screwed. For illustration, the same end wall element 30 in FIG figure 13 shown twice in a row and denoted respectively by the numerals 30a and 30b. The end wall element 30a shown at the front is shown in the unscrewed state and the end wall element 30b shown at the rear is shown in the screwed state.

In the case of the front bulkhead element 30a, the lower end of the vertical support 33, the horizontal cross member 34, the cross brace 14 and the saddle element 11 of the floor element 10 are shown "floating" one above the other or next to one another. A parallelepipedal cantilever 331 is fastened to each vertical support 33 at the upper end (not shown) and at the lower end, for example by welding. The cantilevers 331 extend towards the inside of the end wall element 30a, in which figure 13 so after Left. The brackets 331 each have two continuous elongated holes 332 through which two screws 342 can be guided.

The horizontal cross member 34 comprises two approximately U-shaped profiles 341, each with two horizontal legs 345. The profiles 341 each have two round holes 346 in their end regions. As a result, the front profile 341 and the rear profile 341' can be fastened together on the bracket 331 by guiding the screws 342 through the round holes 346 of the profiles 341, 341' and the elongated holes 332 of the respective bracket 331 and screwing them with the nuts 343. The crossbeams 34 with the legs 345 encompass the upper, the lower and the front of the boom 331, so that a guide is formed along which the crossbeam 34 can be moved when the screws 342 are slightly but not yet tightened. This is made possible by the elongated holes 332.

Overall, there is a width variability for the end wall element 30 which is determined by the length of the elongated holes 332 of the four arms 331 of an end wall element 30 . Due to this width variability, the end wall element 30 can be placed on the floor element 10 with pinpoint accuracy. The structure is as follows: The end wall element 30 is initially screwed loosely, ie the screws 342 and nuts 343 are tightened slightly but not yet firmly. The end wall element 30 is then placed on the base element 10, with centering as described above being effected by the truncated cone 112 and the hollow truncated cone 137. Then the screws 342 and nuts 343 as well as the closing screw 114 (see figure 12 ) tightened so that the end wall element 30 is screwed tightly and securely fastened to the floor element.

The bolted connection has the additional advantage that the bulkhead element 30 can be dismantled, so that transport and maintenance is further simplified.
