Description

Variable container system

Technical Field

The present invention relates to a convertible container system for constructing square room units arranged side by side and one above the other, which can be used for living or working.

Background

Containers of the type described are used everywhere where non-movable installations are considered unprofitable or uneconomical. Containers of the aforementioned type are particularly intended for enabling quick and flexible provision of habitable rooms, for example for use as offices, wards, operating rooms, etc. Typically, such containers are square prefabricated room units that are assembled side-by-side and stacked in the field into a building. In patent application WO 2010/083798 a 1a container system is proposed which enables quick and variable construction and disassembly.

Disclosure of Invention

The present invention has been developed in the context of the aforementioned prior art. The object of the invention is to further improve the container system for constructing room units arranged side by side and/or one above the other, which is variable and known from the prior art, and in particular to simplify the construction and to increase the structural stability and the mechanical load-bearing capacity.

This object is achieved in that the room units respectively comprise: a) a base element serving as an underlying base with a total of four corresponding corner-arranged saddle elements (Satterelement) with inclined guide surfaces for receiving the two end wall elements; b) a top element serving as an upper cover plate with a total of four corresponding saddle elements arranged at the corners, with inclined guide surfaces for resting on the two end wall elements; c) two end wall elements each with two inclined lower corner guides for placing onto the saddle element of the bottom element and each with two inclined upper corner guides for placing onto the end wall element the saddle element of the top element, wherein d) each guide surface of the bottom element is inclined downwardly towards two respectively oppositely arranged saddle elements; and e) each guide surface of the top member is inclined ascendingly towards two oppositely arranged saddle members; and f) the corner guides of the end wall elements have respective complementary slopes to said guide surfaces. The guides of the bottom element and of the end wall element are therefore complementary to one another in terms of their size, shape and inclination. The base element has a total of four saddle elements, specifically two saddle elements for the front end wall element and two saddle elements for the opposite rear end wall element. The inclination of the saddle element is selected such that, when the saddle element is placed on the base element, a force is exerted on the end wall element by the weight of the saddle element, specifically a force component acting toward the center of the end wall element. Another force component perpendicular thereto acts against the opposite end wall element. The end wall element is thus advantageously centered on the base element when it is placed on the base element by the inclined guide surfaces of the saddle element. Thereby, the end wall element slides by gravity into the set position. The opposite end wall elements of the room unit are thus oriented opposite each other. The end wall element is pressed inwards by a further force component. The beveled, inclined guide surface at the upper side of the end wall element enables the top element to be slid into a centred position also when being placed onto the end wall element. In addition, this ensures the positioning of other floors. The elements inserted into one another are thus wedged at the saddle element and are then connected to one another in a slip-proof manner. This results in a self-orienting and self-supporting frame of the room unit.

The following describes advantageous embodiments of the invention with non-limiting additional features.

The guide face of the saddle member may have a convex or concave camber, respectively, and the corner guides of the end wall members have a complementary concave or convex camber, respectively. Whereby the guide surface is advantageously increased. A fully loaded connection of the ball joint type is provided at the saddle element, which ensures a still more accurate positioning by means of the spherical camber, to be precise even in the case of possible manufacturing-related tolerances of the components. The arch can be molded directly onto the saddle element and the corner guides, or can be configured as a correspondingly shaped saddle plate and/or shim plate (autofilter plate) which rests on the saddle element and is fixed at the corner guides.

In order to fix the end wall element to the bottom element and/or the top element, the saddle element can have a truncated cone with an internal thread and the corner guides of the end wall element can have a complementary hollow truncated cone, which can be placed on the truncated cone, wherein the truncated cone and the hollow truncated cone can be connected by a plug screw (abshlussschraube) which can be screwed into the internal thread.

The end wall elements may be detachable to further simplify transport and maintenance. Furthermore, the end wall elements can be adjusted in their width in order to ensure better adjustment.

The vertical beams may have lower and upper angle brackets (auslegger) with elongated holes, into which the horizontal cross beams may be screwed, in order to enable adjustability of the width of the end wall elements.

Alternatively or additionally, the end wall element may be connected with the bottom element and the top element, respectively, by means of a pulling device. The structural elements are thereby additionally tensioned and firmly connected to one another.

Each pulling device is pretensioned by two holding elements, wherein for the lower pulling device the first holding element is fixed in the middle edge region at the inner side of the end wall element and the second holding element is fixed at the upper side of the bottom element, and wherein for the upper pulling device the first holding element is likewise fixed in the middle edge region at the inner side of the end wall element and the second holding element is fixed at the lower side of the top element, so that an imaginary right triangle is opened by the two holding elements and the pulling device.

The pulling device may comprise a steel cable. Preferably, the pulling means comprises a pulling rod. Advantageously, the tension rods can absorb not only tensile forces but also compressive forces, so that the rigidity of the room unit thus formed is significantly improved.

The pulling device is configured such that the pulling stress can be adjusted. This allows the tensile stress or pretension and thus the angle between the bottom element or the top element and the end wall element to be precisely adjusted. For example, the tension rod can have a thread and a socket (fasung) receiving the thread, so that by rotating the tension rod, its length and thus the pretension can be changed.

Two room units fastened next to one another on the longitudinal sides can be tensioned and thereby coupled to one another by means of a cross-shaped arrangement of the pulling devices.

Detailed Description

Preferred embodiments of the invention are described in detail below with reference to the drawings, wherein further advantageous features can be taken from the figures of the drawings.

Fig. 1 shows a perspective view of the structural elements of a room unit 1. For reasons of intuition, these structural elements are "floating", that is to say are shown slightly outside their inserted position. The room units 1 of the container system respectively comprise a lower bottom element 10, a front end wall element 30 and a rear end wall element 30 and an upper top element 20. The top element 20 is substantially structurally identical to the bottom element 10, that is to say relates to identical elements, without structural differences. The bottom element 10 thus becomes a top element 20 inside the container system in such a way that it is fixed "upside down", i.e. with its underside upwards, on the end wall element 30. The two end wall elements 30 are of identical construction, so that the illustrated room unit 1 is constructed essentially from only three different load-bearing

structural elements

10, 20, 30.

The bottom element 10, the end wall element 30 and the top element 20 have a substantially rectangular basic shape, resulting in a square shape for the room unit 1 as a whole. These structural elements mentioned have an outer, approximately rectangular frame made of steel or aluminum. The bottom element 10 and the top element 20 each have two longitudinal struts (laengsstreebe) 13, 23 and outer and central reinforcing

transverse struts

14, 24. The end wall element 30 comprises two beams 33 which are arranged vertically with reference to the base element 10 and are spaced apart by lower and upper horizontally extending cross beams 34 and are connected to each other by welding. With the illustrated frame structure, rectangular openings are produced for the end elements 30 and for the bottom element 10 and the top element 30 and at the sides. All the internal angles of the openings are always 90 degrees. A panel 40 of a suitable material with a window 41 is secured in the opening of the front end wall 30. The side walls are formed from a plurality of non-load bearing panels (panels) 42 and the top element 20 has a cover panel 43. The bottom element 10 forms a walkable floor if the rectangular opening of the bottom element 10 is closed by a plate (not shown). In this way a closed room unit 1 can be built.

The underside of the bottom element 10 rests directly on a horizontal bottom surface or, in the case of a multi-level container system, is fastened to a structurally identical top element 20, thereby forming a floor ceiling element (not shown). The two

structural elements

10, 20 are fixed to one another by screwing.

The bottom element 10 serves as a horizontal base for the end wall element 30. For the placement of the two end wall elements 30, saddle elements 11 are provided at the four corners of the base element 10, respectively, which have inclined guide surfaces 12 on the upper side. These guide surfaces 12 are bevelled and arranged such that their slopes fall correspondingly both towards the outer transverse strut 14 and towards the longitudinal strut 13. With reference to the base element 10, the highest point of the guide surface 12 is thus arranged at the outer corner, while the lowest point is arranged oppositely at the inner corner.

The end wall elements 30 have at the underside of the vertical beams 33 downwardly directed, inclined corner guides 31 which are inclined towards the guide surfaces 12 of the saddle elements 11 of the bottom element 10 and can thus be placed thereon. Due to the inclined guide surface 12 of the bottom element 10 and the complementarily inclined corner guide 31 of the end wall element 30, the end wall element 30 is not only pressed downwards by its weight, but is additionally centered. Furthermore, the end wall elements are pressed inward toward the longitudinal struts 13 as far as the stop elements 15 provided for this purpose, so that they assume the desired position.

Since the top member 20 is of substantially identical construction to the bottom member 10, it has four identical saddle members 21 with inclined guide surfaces 22 at its two corners, but these guide surfaces are directed downwardly because the top member 20 is turned 180 degrees "upside down". The guide surfaces 22 serve to fix the top element 20 to two end wall elements 30 which have complementary upper corner guides 31. The top element 20 is thus centered on the two end wall elements 30 in the longitudinal and transverse direction only by its weight.

The fastening of the

structural elements

10, 20, 30 is effected by means of

tie rods

50, 51.

There are feasible solutions: the room units 1 are completely preassembled and transported as finished room units 1 and built and stacked on site. This option can be advantageous in the case of smaller container systems, since the building up can be carried out more quickly and more cost-effectively by preassembly. In the case of medium-and large-sized container systems, it is advantageous if the room units 1 are transported in a disassembled state and assembled at the building site.

Fig. 2 shows a perspective view of a room unit 1, which is formed by joining together the structural elements of fig. 1. The lower bottom element 10 serves as a base for the room unit 1 shown. The front and rear

end wall elements

30, 30 are placed on the base element 10. At the inner side of the vertical beam 33 of the end wall element 30, one end of the lower tie rod 50 is fixed, while its other end is fixed at the longitudinal strut 13 of the bottom element 10, so that the tie rod 50 forms a right triangle with the respective sections of the vertical beam 33 and of the longitudinal strut 13. On the end wall element 30 is placed an upper top element 20 which is fixed in the same way at the vertical beam 33 of the end wall element 30 by means of an upper pulling rod 51. A square overall shape is created for the room unit 1.

Fig. 3 shows a perspective view with four base elements 10 and with two inner walls 44. In order to build a container system from four room units 1 (see fig. 2), four bottom elements 10 are arranged side by side according to the illustration. Above the four bottom elements 10, two inner walls of the container system are shown. For reasons of intuition, the inner wall 44 is "floating", that is to say, is shown slightly above the position in which it is arranged.

The single inner wall 44 is formed by two structurally identical end wall elements 30, respectively, which are fixed to one another. A total of four end wall elements 30 are thus shown. A multi-level container system with a plurality of room units 10 arranged side by side and on top of each other can thus be built up from only three components, namely a bottom and a

top element

10, 20 and an end wall element 30, respectively.

The two end wall elements 30 are in each case fastened to one another in such a way that their chamfered upper and lower corner guides 31 form a common downwardly directed groove 39 and a common upwardly directed groove 38, which are in each case approximately V-shaped in cross section. The two base elements 10 are each arranged abutting against one another at the end face, so that the two saddle elements 11 abutting against one another are each formed with their inclined guide surfaces 12 with a common groove 19 (rounding) which is complementary to the lower groove 39 formed by the two end wall elements 30. The two end wall elements 30, which jointly form the inner wall 44, can be plugged with the groove 39 onto the tongue-and-groove 19, whereby the two bottom elements 10 are firmly connected to each other by the clamping action of the groove 39. Since the bottom element 10 is identical to the top element 20, their saddle elements 21 are configured with identical tongues (not shown) which are likewise complementary to the upper groove 38 formed by the two end wall elements 30 and by means of which the two top elements 20 can be firmly connected to one another in the same way owing to the clamping action of the groove 38.

When the room unit 1 is assembled, the end wall elements 30 or the inner walls 44 are fixed after being placed on the base element 10 in such a way that they are fixed with the lower tie rods 50 on the base element 10 immediately after insertion. This contributes firstly to the operational safety, since the end wall element 30 is prevented from possibly tipping over. The traction rod 50 is configured such that its tensile stress is adjustable. The tensile stress and the position of the end wall element 30 can thus be adjusted during further construction. Furthermore, the

tension rods

50, 51 significantly improve the stability of the room unit, since they can absorb and dissipate not only tensile forces but also compressive forces.

The fastening of the structural elements of the container system is to be understood as a permanently releasable fastening or plug-in connection, since the container system can be used when required and can be quickly built up and disassembled again.

Fig. 4 shows a perspective view of a container system with four room units 1. It is shown that a single outer wall is formed by one end wall element 30, while a single inner wall 44 is formed by two end wall elements 30. The top element 20 is fixed to the end wall element 30 by means of the upper tie rods 51.

In the case of a multilayer construction, structurally identical bottom elements 10 are fastened to the top element 20, to which bottom elements end wall elements 30 and top element 20, etc., are in turn fastened.

Fig. 5 shows a perspective side detail of the lower corner region of the room unit 1 of fig. 1 with structural elements shown "floating" up and down. One of the four corners of the base member 10 is shown with saddle members 11 for receiving the vertical beams 33 of the end wall members 30. The saddle element 11 is wedge-shaped and has an upper guide surface 12 with a double inclination or a chamfer. On the one hand, the guide surface 12 slopes downward in the direction a toward the front crossbar 14. On the other hand, the guide surface 12 is inclined downward in the direction b toward the longitudinal stay 13. At the upper and lower ends of the vertical beam 33, complementarily inclined corner guides 31 are provided, which can be placed onto the saddle element 11. By means of the saddle element 11, the end wall element 30 is centered on the transverse strut 14 in the direction a and is also pressed in the direction b, i.e. toward the longitudinal strut 13 of the base element, to be precise to the edge of the stop element 15.

In order to compensate for manufacturing tolerances and to obtain a still better connection and centering, a saddle plate 16 is provided which is flat on the underside and convexly arched upwards on the upper side and is fastened to the corner guides 31 or to the support plate 36. Accordingly, a shim plate 36 with a complementary concave curvature is fastened to the corner guide 31.

At the upper side of the longitudinal strut 13, a holding element 52a is fastened for fastening the lower tension rod 50.

Fig. 6 shows a perspective front detail view of the structural element of fig. 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. It is also shown that the horizontal cross member 34 of the end wall element 30 is designed as an angular U-shaped profile with downwardly directed legs 35 of different lengths. The U-shaped profile of the transverse strut 34 thus serves as a guide when it is placed on the transverse strut 14.

Fig. 7 shows a perspective detail view of the assembled

construction elements

10 and 30 of fig. 5. The saddle element 11 is shown with the vertical beam 33 resting on, wherein the saddle plate 16 and the shim plate 36 are arranged between the corner guides 31 and the saddle element 11. The stop 15 limits the movement of the end wall element 30 in the direction b, i.e. in the direction of the longitudinal strut 13 (see fig. 5). The tie rods 50 are fixed at the retaining elements 52a, which in turn are fixed at the longitudinal struts 13.

Fig. 8 shows a perspective detail of the assembled

construction elements

10 and 30 of fig. 6. The saddle element 11 is shown with the vertical beam 33 resting on, wherein the saddle plate 16 and the shim plate 36 are arranged between the corner guides 31 of the vertical beam and the saddle element 11. Furthermore, it is shown that the leg 35 surrounds the upper region of the transverse strut 14 and thus serves as a guide for the transverse strut 34.

Fig. 9 shows a perspective view of a container system with four room units 1, wherein the front room unit is shown suspended. The bottom element 10 is in each case fastened to the end wall element 30 with a pretension by means of a lower tension rod 50, while the top element 20 is in each case fastened to the end wall element 30 with a pretension by means of an upper tension rod 51. The fastening of the

tie rods

50, 51 is effected by a lower holding element 52a, an intermediate holding element 52b and an upper holding element 52c (not shown, see fig. 11). The

tie rods

50, 51 of two room units 1 arranged next to one another run parallel to one another. These room units 1 are connected to each other by screwing.

Fig. 10 shows a perspective detail of a second embodiment of the container system with two room units 1, 1'. Here, the upper and

lower tie rods

50, 51 of two room units 1 arranged next to one another do not run parallel to one another, but cross one another and form an X shape. The lower tension rod 50, which is fastened to the longitudinal strut 13 of the base element 10 by means of the retaining element 52a, is not fastened to the end wall element 30 resting on the base element 10, but is fastened to the end wall element 30 ' resting on the base element 10 ' arranged next to it, using the retaining element 52b '. Correspondingly, the lower tie rod 50 'which is fixed flat at the base element 10' is fixed to the end wall element 30 which is placed on the mentioned base element 10 arranged beside it.

In the same way, the upper tie rods 51 fixed at the longitudinal struts 2 of the top element 20 are fixed at the end wall elements 30 ' resting on the top element 20 ' arranged beside them, while the upper tie rods 51 ' fixed at the longitudinal struts 23 ' of the top element 20 ' are fixed at the end wall elements 30 resting on the top element 20 arranged beside them. Likewise, the upper tie rods 51, 51' intersect and form an X-shape.

The room units 1, 1' arranged next to one another are thus additionally fastened to one another crosswise and tensioned against one another.

Fig. 11 shows a perspective detail of the second embodiment of the cross-tensioning with the tension rods 50, 50 ', 51' as seen from obliquely below in fig. 10. The upper retaining element 52c is shown in this view.

Fig. 12 shows a perspective detail of the third embodiment. One of the four corners of the base member 10 is shown with saddle members 11 for receiving the vertical beams 33 of the end wall members 30. The embodiment shown differs from the above-described embodiment in particular by the saddle element 11. For the purpose of illustrating the function, four identical saddle elements 11 are shown side by side in fig. 12 and are designated by the

reference numerals

11a, 11b, 11c and 11d, respectively. The saddle element 11 is wedge-shaped and has an upper guide surface 12 with a double inclination or a chamfer angle as described above in the other embodiments. However, the surface 12 is not convex but rather flat. In order to obtain still better connection and centering when placing the vertical beam 33, a truncated cone 112 with an internal thread 113 is instead fixed on the surface 12. For the internal thread 113, a plug screw 114 with an adapted external thread 115 is provided. Between the saddle element 11 and the plug screw 114, a shim plate 136 is arranged, which can be fastened to the saddle element 11 with the plug screw 114.

For saddle member 11b, the washer 136 and the plug screw 114 are shown "floating" on top of each other. Backing plate 136 has a hollow frustoconical portion 137 chamfered at the lower face, which is complementary to frustoconical portion 112 and has an inner diameter slightly larger than the outer diameter of frustoconical portion 112, so that backing plate 136 can be inserted onto frustoconical portion 112.

This is shown in saddle member 11 a. The chamfer angle of the surface 12 of the saddle element 11 is compensated for by the lower chamfer angle of the hollow truncated cone 137. The shim plate 136 rests on the surface 12 of the saddle member 11 a. The plug screw 114 is threaded into its internal thread 113 so that the plug screw washer 117 presses against the surface 138 of the hollow frustoconical portion 137 of the backing plate 136. Since the washer 117 has a larger diameter than the surface 138 of the hollow truncated cone 137, the hollow truncated cone 137 or the shim plate 136 is reliably held on the saddle element 11.

In the saddle member 11c, the vertical beam 33 of the end wall member 30 is shown suspended thereon. At the upper and lower ends of the vertical beam 33, corner guides 31 are provided which are inclined complementarily to the saddle element 11 and can be placed on the saddle element 11. It is shown that the support plate 136 is fixed, for example by welding, to the underside of the beam 33 or to the corner guide 31. The entire end wall element 30 is thereby fixed to the saddle element 11 by screwing by means of the stopper screw 114. This is shown in saddle member 11 d.

Fig. 13 shows a perspective detail of the third embodiment from the front. One of the four corners of the base member 10 is shown as in fig. 12 with a saddle member 11 for receiving the vertical beams 33 of the end wall member 30 with a truncated cone portion 112. In this third embodiment, the two vertical beams 33 and the two horizontal cross beams 34 of the end wall element 30 are not welded firmly to one another (as is shown, for example, in fig. 5), but they are constructed so as to be screwable. For the sake of clarity, two identical end wall elements 30 are shown in fig. 13 one behind the other, and are correspondingly designated by the

reference numerals

30a and 30 b. The end wall element 30a shown at the front is shown in the non-screwed state, while the end wall element 30b shown at the rear is shown in the screwed state.

In the front end wall element 30a, the lower ends of the vertical beams 33, the horizontal cross beams 34, the cross braces 14 and the saddle elements 11 of the base element 10 are shown "suspended" one above the other or side by side. On each vertical beam 33, a square angle bracket 331 is fixed (e.g. by welding) at the upper end (not shown) and the lower end, respectively. The angle bracket 331 extends towards the inside of the end wall element 30a, i.e. to the left in fig. 13. The angle brackets 331 each have two through-going oblong holes 332 through which two screws 342 can be guided.

The horizontal transverse beam 34 comprises two substantially U-shaped profiles 341 with two horizontal legs 345. The profile 341 has two circular holes 346 in each case in its end region. The front and rear profiles 341, 341 'can thus be jointly fixed to the angle bracket 331 in such a way that the screws 342 are guided through the round holes 346 of the profiles 341, 341' and the corresponding long holes 332 of the angle bracket 331 and screwed with the nuts 343. The transverse beam 34 with the leg 345 encompasses the upper, lower and front sides of the angle bracket 331, so that a guide is formed along which the transverse beam 34 can be moved when the screw 342 is slightly screwed on, but not yet firmly screwed on. This is achieved by the elongated hole 332.

Overall, a width variability results for the end wall element 30, which is determined by the length of the oblong holes 332 of a total of four angle brackets 331 of the end wall element 30. This width variability allows the end wall element 30 to be placed exactly on the base element 10. The construction was carried out in the following manner: end wall element 30 is first loosely threaded, that is, screw 342 and nut 343 are slightly threaded, but not yet firmly tightened. The end wall element 30 is then placed on the base element 10, wherein the centering is effected as described above by the truncated cone 112 and the hollow truncated cone 137. Screw 342 and nut 343, and plug screw 114 (see fig. 12) are then tightened firmly so that end wall member 30 is firmly screwed and securely fastened to the base member.

Screwing has the additional advantage that the end wall element 30 can be detached, thereby further simplifying transport and maintenance.
