Description

Title: Construction system and method for forming the construction system

The invention relates to a construction system which is suitable, for example, as a post against which wall elements can be placed.

The invention also relates to a method for forming the construction system.

Such construction systems are known per se. A known construction system comprises an elongated construction element with, for example, a substantially U-shaped or C-shaped cross-section. The known construction system is used, for example, as a post 10 against which wall elements are placed. The known construction system can be of a light weight and can be manufactured inexpensively.

However, the known construction system has the disadvantage that the construction system has a limited rigidity. It is known to increase the rigidity of a construction system, for example by manufacturing the elongated construction element from a thicker material, or even making it solid. This has the disadvantage that the weight of the construction system increases, or even increases considerably. It is also known to connect reinforcing bodies to the construction system, such as for example truss constructions. However, this has the disadvantage that the construction system becomes complicated and expensive to manufacture.

It is an object of the invention to provide a construction system that retains the advantages of the known construction system, but obviates the aforementioned disadvantages.

To that end, according to the invention, a construction system is provided, comprising an elongated outer work and an elongated inner work, wherein the outer work is provided with an inner space for receiving the inner work, wherein the construction system can be brought into an assembled state for, for example, the compact be able to transport and / or store the construction system and can be brought into a assembled state for use of the construction system, wherein in the assembled state the interior is loosely and suitably accommodated, at least substantially, within the interior space for substantially counteracting of a deformation of a cross-section of the outer work and / or to increase a rigidity of the construction system, wherein in the assembled state 10 a center line of the inner work extending substantially in a longitudinal direction of the inner work and a substantially in a longitudinal direction of the outer work center line of the outer work extend substantially parallel to each other, and wherein the inner work and the outer work transverse to their respective center lines have such a cross-section that from the assembled state the inner work can be, at least substantially, inside the inner space placed.

In this case, the inside work, in the assembled state, can be manufactured, stored and / or transported separately from the outside work, and for instance only be assembled just before use (or sale). The manufacture, storage and / or transport of the inner work separately from the outer work can be carried out more efficiently than in the assembled state, for instance in that a plurality of inner works and / or outer works can be stacked more efficiently, for instance more compact, than a plurality of construction systems.

Since the inner work, at least in the assembled state, is loosely fitted, at least substantially, in the inner space, the construction system can be assembled from the assembled state without adding fastening means. This offers 1029063 the advantage that the construction system can be assembled simply, cheaply and with simple means, for example by hand.

The inner work, at least substantially, contained within the inner space reduces a deformation of the cross-section of the outer work and / or increases the rigidity of the construction system because, in use, a force exerted on the construction system will be absorbed at least in part by the inside. This offers the advantage that the construction system, at least in the assembled state, offers a greater resistance to, for example, torsion and / or bending.

Preferably, at least in the assembled state, the outer work is provided with an opening extending substantially in the longitudinal direction of the outer work, through which, from the assembled state, the inner work can be placed, at least substantially, within the inner space. This offers the advantage that the inner work can simply, at least substantially be brought into the inner space from the assembled state. Preferably, at least in the assembled state, the opening extends over a full length of the outer work. This offers the advantage that the inner work can be placed very simply, or at least substantially, within the inner space. The inner work can, for example, be brought into the inner space substantially parallel to the outer work.

The outer work and / or the inner work is preferably adapted to keep the inner work and the outer work fixed relative to each other, at least in the assembled state. This offers the advantage that the inner work and the outer work remain fixed relative to each other, whereby a great resistance to bending and / or torsion is obtained. Preferably, the inner work, at least in the assembled state, is form-fittingly incorporated substantially within the inner space.

1029063 4

Preferably, the outer work, viewed in a cross-section, at least in the assembled state, is closed in itself. This offers the advantage that the outer work has a greater resistance to deformation, such as bending or torsion, than when the outer work, in use, is not closed in itself.

The outer work preferably comprises a tube with, at least in the assembled state, a substantially rectangular cross-section. This offers the advantage that a construction system is obtained with an outer circumference which is rectangular in cross-section, which renders the construction system suitable for many applications, such as for example as a stand against which (flat) wall elements can be placed, or beam for manufacturing buildings or stands, for example.

Preferably the outer work comprises a first elongated sub-outer work and a second elongated sub-outer work. This offers the advantage that it can be realized in a simple manner that the inner work from the assembled state can be placed, at least substantially, within the first sub-outer work, wherein, after placing the inner work, the second sub-outer work can be added for forming of the outside work. Preferably, the first and second partial external parts are herein connectable directly to each other, that is, without the intervention of, for example, the internal parts or another element. Preferably the first and the second sub-exterior are releasably connectable to each other. This offers the advantage that the construction system can be brought from the assembled state back into the assembled state. As a result, the construction system can for instance also be used in temporary constructions, wherein after construction of the temporary construction the construction system can be transported and / or stored more efficiently, for example more compactly.

1029063 5

The inner work preferably comprises, at least in the assembled state, an elongate element with a substantially cross-shaped cross-section. In one embodiment, at least in the assembled state, each of the four corner points of the substantially cross-shaped element of the inner work abuts in one of the four corners of the substantially rectangular sleeve of the outer work. This offers the advantage that the innerwork can efficiently prevent substantially a cross-sectional deformation of the outerwork and / or increase the rigidity of the construction system, by forming diagonals in the cross-section of the construction system.

Preferably the inner work comprises a first and a second elongated part inner work. This offers the advantage that from the non-assembled state, the inner work, for instance substantially within the inner space of the outer work, can be assembled.

Here, the opening extending substantially in the longitudinal direction of the outer work need not be of such a size that the inner work as a whole can be placed through the opening within the inner space.

Preferably, the first and second part inner parts both have a substantially V-shaped cross-section, and, at least in the assembled state, abut each other near their centers. This offers the advantage that from the non-assembled state, the substantially cross-shaped element of the inner work, for example substantially within the inner space of the outer work, can be assembled.

Here, the opening extending substantially in the longitudinal direction of the outer work need not be of such a size that the substantially cross-shaped element of the inner work as a whole can be placed through the opening within the inner space.

The inner work and / or the outer work is preferably made of a material in which fastening means, such as screws, can be fixed without preparatory action. This means that, for example, screws can be screwed directly into the material without first having to drill a hole. This offers the advantage that the construction system can be easily processed, for example by providing screw connections between construction systems and / or the construction system and other building elements. The inner work and / or the outer work is preferably made of steel sheet, for example thin-walled steel sheet, for example with a thickness of preferably less than 1.5 mm, more preferably less than 1 mm, most preferably about 0.6 mm. j

The invention further relates to a package provided with: at least one inner work and at least one outer work of the construction system according to the invention.

FIG. 1a shows a cross-section of a first embodiment of a construction system 1 according to the invention in an assembled state. FIG. 1b shows a cross-section of the first embodiment 5 of the construction system 1 shown in FIG. la in an uncomplicated state. The construction system 1 can be brought into the assembled state for, for example, the compact transport and / or storage of the construction system 1. The construction system 1 can be brought into the assembled state for use of the construction system 1.

With reference to Figs. 1a and 1b, the construction system 1 comprises an elongated outer work 2 which extends in a longitudinal direction transversely to the one shown in Figs. 1a and 1b. The construction system also comprises an elongated inner work 4 which extends in a longitudinal direction transversely to the one shown in Figs. 1a and 1b. In the assembled state shown in FIG. 1a, therefore, a center line of the inner work extending substantially in the longitudinal direction of the inner work 4 and a center line of the outer work 2 extending substantially in the longitudinal direction of the outer work 2 extend substantially parallel to each other. It will be appreciated that in the non-assembled state of FIG. The center lines of the inner work 4 and the outer work 2 do not necessarily extend parallel to each other.

In the example of Figs. 1a and 1b is a cross-section of the inner work 4 and / or the outer work 2 substantially constant in the longitudinal direction of, respectively, the inner work 4 and / or the outer work 2.

The outer work 2 is provided with an inner space 6 for receiving the inner work 4. FIG. 1a shows the interior 4 incorporated within the interior 6 in the assembled state of the housing.

; I

construction system 1. In FIG. 1a the inner work 4 is completely included within the outer work 2.

In the example of Figs. 1a and 1b, the outer work 2 comprises a first elongated sub-outer work 8 and a second elongated sub-outer work 10. The inner work 4 comprises a first elongated sub-inner work 12 and a second elongated sub-inner work 14.

In FIG. 1a it can be seen that the outer work 2, at least in the assembled condition shown there, is closed in itself, seen in the cross-section. The first and the second sub-works 8, 10 are in this J

For example, at least in the assembled state, directly connected to each other, without the intervention of, for example, the interior 4 or another element. The outer work 2 closed in itself has a greater resistance to deformation, such as bending or torsion, than an outer work that is not closed in itself. In the assembled state of FIG. 1a the outer work 2 comprises a tube with a substantially rectangular cross-section, in this example a substantially square cross-section. Since in FIG. 1a, the cross-section of the outer work 2 is substantially constant in the longitudinal direction of the outer work 2, the construction system 1 in FIG. 1a is a beam with a substantially constant square cross-section.

FIG. 1b it can be seen that the first sub-exterior work 8 and the second sub-exterior work 10 are each designed as an elongate element with a substantially U-shaped cross-section. Furthermore, it can be seen in FIG. 1b, at least in the assembled state shown therein, that the outer work 2 is provided with an opening 16 extending substantially in the longitudinal direction of the outer work 2, through which, from the assembled state, the inner work 4 can enter inside the inner space 6 be placed. In this example, the opening 16 extends over a full length of the outer work 2.

In the assembled state, the inner work 4 is loosely and suitably accommodated within the inner space 6. As a result, the inner work 4 in 1029063 9 can substantially prevent a deformation of a cross-section of the outer work 2 and / or increase a rigidity of the construction system 1. In this example, the outer work 2 and the inner work 4 are adapted to keep the inner work 4 and the outer work 2 fixed relative to each other, at least in the assembled state. In this example, the dimensions of the inner work 4 and the outer work 2 and the shape of the inner work 4 and the outer work 2, viewed in the cross-section, are selected for this purpose such that the inner work 4 and the outer work 2, at least in the assembled state, be held fixed relative to each other.

In FIG. 1a it can be seen that the interior 4, at least in the assembled condition shown there, comprises an elongate element with a substantially cross-shaped cross-section. Each of the four corner points 18, 20, 22, 24 of the substantially cross-shaped element of the inner work 4 abuts in one of the four corners 26, 28, 30, 32 of the substantially rectangular sleeve of the outer work 4. This offers the advantage that the resistance of the construction system 1 to torsion and / or bending is efficiently increased in that it forms substantially cross-shaped elements diagonals in the cross-section of the construction system 1 and thereby substantially distorts the cross-section of the construction system 1 counteracts. The cross-shaped element can hereby be made of relatively light weight, so that the construction system 1 can be made of relatively light weight. In FIG. 1a, the substantially cross-shaped element 25 is formed by the first and the second part inner work 12, 14, both of which have a substantially V-shaped cross-section and abut each other near their centers 34, 36. The first and second part inner workings 2, 14 are provided near their centers 34, 36 with an abutment surface 38, 40. In the assembled state, the abutment surfaces 38, 40 of the first and the second part inner workings 12, 14 abut each other.

1 0 29 063 10

Therefore, at least in the case shown in FIG. 1a shows that the inner work 4 abuts an inner side of the outer work 2 along four lines extending substantially in the longitudinal direction of the outer work 2 in the corners 26, 28, 30, 32. The lines can also be virtual lines to be. The dimensions of the inner work 4 and the outer work 2 and / or the shape of the inner work 4 and the outer work 2, seen in the cross-section, are predetermined for this purpose in such a way that the inner work 4 is therefore form-fittingly incorporated within the inner space 6. It is it is also possible that the inner work 4, at least in the assembled state, is included in a force-locked manner substantially within the inner space 6, so that the inner work 4 rests against the inside of the outer work 2 under some pretension.

The construction system 1 described so far can be assembled as follows from the non-assembled state to the assembled state. The outer work 2 and the inner work 4 as described with reference to Figs. 1a and 1b are provided. The inner work 2 is placed loosely and fittingly within the inner space 6, wherein in the assembled state the center line of the inner work 4 and the center line of the outer work 2 extend substantially parallel to each other. The outer work 2 and the inner work 4 here have such a cross-section that, from the assembled condition, the inner work 4 can be placed, at least substantially, within the inner space 6. In this example, the inner work 4 is placed through the opening 16 in the inner space 6 of the outer work 2. The inner work 4 and the outer work 2 herein have a cross-section such that from the assembled state the inner work 4 can be placed within the inner space 6 of the outer work 2.

More in particular, the first and the second part inner work 12, 14 are placed through the opening 16 in the inner space 6.

The first sub-interior 12 is placed in the first sub-exterior 8 1029063 11 such that the corner points 18, 20 of the first sub-interior 12 substantially abut the corners 26, 28 'of the first sub-exterior 8. The second sub-interior 14 becomes placed the first sub-exterior 8, the corner points 22, 24 of the second sub-interior 14 substantially abutting the corners 30, 32 'of the first sub-exterior 8 and the abutment surface 40 of the second sub-interior 14 abutting the abutment surface 38 of the first sub-interior 12. In this example, the first and the second sub-interior 12 and 14 are substantially similar and equally large and each substantially symmetrical with respect to a plane transversely to, respectively, the contact surfaces 38 and 40 through, respectively, the centers 34 and 36. The first and the second sub-interior 12, 14 can therefore be of identical design. This offers the advantage that exchanging the first and the second sub-interior 12, 14 when assembling the construction system 1 has no consequences for the construction system. This reduces the chance of assembly errors when assembling the construction system 1. Moreover, this allows the construction system to be manufactured more efficiently and cheaper, since fewer different parts are used.

In the example of Figs. 1a and 1b, the first and the second sub-interior 12, 14 are loosely abutting. Therefore, no fastening means are required in this example to connect the first and the second part interior 12, 14 to each other. This offers the advantage that the interior 4 of the construction system 1 can be assembled simply and inexpensively, for example by hand.

Subsequently, the second sub-outer work 10 is placed against the first sub-outer work 8 so that the outer work 2 is formed and, in this example, is closed in itself. In this example, the second sub-exterior work 10 directly engages the first sub-exterior work 8, that is to say without intervention of, for example, the interior work 4 or another 1,029,063,112 element. Thus, the construction system 1 is obtained in the assembled state, wherein in the assembled state the inner work 4 is loosely and suitably accommodated within the inner space 6 of the outer work 2.

The outer work 2 can be formed by connecting the first and the second sub-outer work 8, 10 to each other. In one embodiment, the first and the second sub-exterior work 8, 10 are arranged such that the first and the second sub-exterior work can be connected by hand without the use of tools. To this end, in the example of FIG. the first sub-exterior structure 8 is provided with at least one protrusion 42, for example a plurality of protrusions extending in the longitudinal direction of the first sub-exterior structure 8, and it is second part exterior work provided with at least one with the at least one! of recess 42, corresponding recess 44, for example a plurality of recesses extending in the longitudinal direction of the second sub-exterior 10, for connecting the first and second sub-exterior 8, 10. It is of course also possible that the second sub-exterior 10 is provided with at least one protrusion and the first sub-external work 8 is provided with at least one recess, or that the first and the second sub-external work 8, 10 are both provided with at least one recess and at least one protrusion. Thus, the first and the second subterranean work 8, 10 are releasably connectable. It is also possible to make the sub-external works 8, 10 detachably connectable in a different manner, for instance by providing a clamping force and / or frictional force between the two sub-external works 8, 10, at least in the assembled state, providing a click connection between the first and the second sub-exterior works 8, 10, or by connecting the first and the second sub-exterior work by means of screws. It is also possible to connect the sub-external works 8, 10 substantially inseparably to each other, for example by gluing the two sub-external works 8, 1029063 13 10, or providing an inseparable snap connection between the first and the second sub-external work 8, 10 .

In the non-assembled state, for example, the inner work 4 can be manufactured separately from the outer work 2, stored and / or transported.

The manufacture, storage and / or transport of the inner work separately from the outer work can for instance take place more efficiently than in the assembled state, because a plurality of inner works and / or outer works can be stacked more efficiently, for instance more compact, than a plurality of construction systems. It can therefore also be advantageous to provide the construction system 1, or a plurality of such construction systems, in the assembled state in the form of a package, wherein the construction system, or the plurality of construction systems, is compactly bundled, for example.

FIG. 2 shows a cross-section of a second embodiment 15 of the construction system 1 in an assembled state. In FIG. 2, the outer work 2 comprises an elongated first sub-outer work 8 'with a substantially C-shaped cross-section and an elongated second sub-outer work 10' with a substantially U-shaped cross-section. The outer work 2 is arranged such that an outer circumference of the cross-section of the outer work 2 is substantially free of protrusions and / or staggers. To this end, the first sub-exterior work 8 'is provided with offset surfaces 46, 48 for receiving lips 50, 52 of the second sub-exterior work 10'. As a result, the lips 50 and 52 extend substantially in the same plane in which side walls 54 and 56 of the first sub-outer work 8 ', respectively, extend. The first and the second part external parts 8 ', 10' can be connected as explained with reference to Figs. la, lb and lc.

In FIG. 2, the inner part 4 comprises the first part inner part 12 'and the second part inner part 14'. The inner parts 12 'and 14' each have the substantially V-shaped cross-section and are provided with contact surfaces 38, 40 near their centers 34, 36 1029063 14. In FIG. 2, the first part inner work 12 'is provided with a substantially right-angled settlement 58 which is arranged such that, at least in the assembled state, end surface 62 extends substantially parallel to and abuts against edge 66 of the first part outer work 8'. The second sub-interior 14 'is provided with a substantially right-angled settlement 60 which is arranged such that, at least in the assembled state, end face 64 extends substantially parallel to and abuts against edge 68 of the first sub-exterior 8'.

The construction system 1 shown in FIG. 2 can be assembled from the non-assembled state as described in relation to FIG. la, lb and lc. Because the first sub-exterior work 8 'has a substantially C-shaped cross-section, the sub-interior work 12' and 14 'will be placed in the corners 28 and 30 when placed inside the inner space 6 behind, respectively, the end flanges 66 and 68. This offers the advantage that even before the second sub-exterior work 10 'is placed against the first sub-exterior work 8', the sub-interior works 12 ', 14' are loosely and suitably accommodated within the inner space 6, such that the chance that the sub-interior work 12 ', 14 getting out of the interior space 6 is reduced.

FIG. 3 shows a cross-section of a third embodiment of the construction system 1 in an assembled state. In FIG. 3, the outer work 2 comprises an elongated first sub-outer work 8 "with a substantially L-shaped cross-section and an elongated second sub-outer work 10" with a substantially L-shaped cross-section. In this example, the first and the second sub-exterior parts 8 ", 10" are, at least substantially, uniform. This offers the advantage that the construction system 1 can be manufactured more efficiently and cheaper, since fewer different parts are used. As in FIG. 2 is in FIG. 3, the outer work 2 is arranged such that an outer circumference of the cross-section of the outer work 2 is substantially free of protrusions and / or staggers. To this end, the first sub-external body 8 "is provided with staggered surface 46 for receiving lip 50 'of the second sub-external body 10". As a result, the lip 50 'extends substantially in the same plane in which side wall 54 of the first sub-exterior 8 "5 extends. The first and the second sub-exterior 8", 10 "can be connected as explained with reference to Figs. 1a, 1b and lc, for example by means of protrusions and recesses.

In FIG. 3, the inner part 4 comprises the first part inner part 12 "and the second part inner part 14". The inner parts 12 "and 14" each have the substantially V-shaped cross-section and are provided with contact surfaces 38, 40 near their centers 34, 36. In FIG. 3, the first sub-interior 12 "is provided with two substantially perpendicular settings 58, 70 which are arranged such that, at least in the assembled state, the end surface 62 extends substantially parallel to and abuts the edge 66 of the first sub-exterior 8 and that second end face 72 extends substantially parallel to the end face 62. In this example, the first and the second sub-interior 12 ", 14" are substantially uniform and equally large and each substantially symmetrical with respect to a plane extending transversely to the contact surfaces 38, 40. The first and second sub-interior parts 12 ", 14" can therefore be of identical design. This offers the advantage that exchanging the first and the second sub-interior 12 ", 14" when assembling the construction system 1 has no consequences for the construction system 1. This reduces the risk of assembly errors when assembling the construction system 1. Moreover, this can the construction system 1 can be manufactured more efficiently and cheaper.

The construction system 1 shown in FIG. 3 can be assembled from the non-assembled state as follows. The first sub-interior 12 "is placed against the first sub-exterior 8" such that the corners 18, 20 of the first sub-interior 12 "substantially abut the corner points 26, 28 of the first sub-exterior 8". The second sub-interior 14 "is positioned against the second sub-exterior 10" such that the corner points 22, 24 of the second sub-interior 14 "substantially abut the corners 30, 32 of the second sub-exterior 10". Subsequently, the first and the second part external parts 8 ", 10" are placed against each other to form the outside part 2. Here, the first and the second part external parts 8 ", 10" can be connected as explained with reference to Figs. 1a, 1b and 1c, for example by means of recesses and bulges.

FIG. 4 shows a cross-section of a fourth embodiment of the construction system 1 in an assembled state. In FIG. 4, the contact surfaces 38 ', 40' of the sub-interior pieces 12 "', 14"' are adapted to engage with each other. In FIG. 4, the contact surfaces 38 'and 40' are provided for this purpose with settings 74, 76 and 78, 80, respectively. In FIG. 4, the first and the second sub-interior 12 '", 14"' are of the same shape and size. The first and the second sub-interior 12 '", 14" "can be of identical design. It is also possible that the contact surfaces 38 ', 40' engage with each other by means of protrusions and recesses. Interlocking the contact surfaces 38 ', 40' offers the advantage that, in use, the contact surfaces 38 ', 40' cannot shift relative to each other, for example in a direction transverse to the longitudinal direction of the construction system 1. As a result the resistance to the deformation of the cross-section of the outer work 2 is increased and / or the rigidity of the construction system 1 is increased.

In an embodiment the inner work 4 and / or the outer work 2 of the construction system 1 are made of metal sheet, for example steel sheet, more in particular of thin-walled steel sheet, for example with a thickness of preferably less than 1.5 mm, more preferably less than 1 mm, most preferably about 0.6 mm. The inner work 4 and 1029063 17 and the outer work 2 can, for example, be manufactured by setting or bending on, for example, a press bench or press brake. The inner work 4 and the outer work 2 can advantageously be manufactured by means of roll forming. j

This offers the advantage that the inner work 4 and the outer work 2 can be manufactured in a simple and / or inexpensive manner. The first and the second part inner work and the first and the second part outer work can each be manufactured by, for example, setting, bending and / or roll forming. Construction system 1 is preferably made of a material, such as, for example, the said thin-walled steel plate, in which fastening means, such as screws, can be fastened without preparatory action. This means that it is not necessary, for example, to drill holes for being able to place the screws in those holes.

As a result, the construction system 1 can be used in a simple manner for forming structures with the aid thereof, such as for instance walls, buildings or stands, or other applications. The thin-walled steel plate is extremely suitable for the applications mentioned. The inner work 4 and / or outer work 2 of the construction system 1 is herein for instance provided with a rust-resistant protective layer, such as lacquer or a metal layer such as, for example, zinc or nickel. The outer work of the construction system 20 preferably has a diameter that is smaller than 130 x 130 mm, more preferably smaller than 100 x 110 mm, most preferably about 60 x 60 mm.

In one embodiment of the construction system, the outer work is provided in the longitudinal direction with distance markings. The spacer markers are, for example, mutually substantially at a distance of 50-100 mm, for example at 50 mm or 100 mm. This makes it very easy for a user to determine a length of the construction system, for example when the length of the construction system must be reduced in order to make the construction system 30 suitable for a desired application. It is also possible to use the 1029063 18 distance markers for reading a distance and / or position. The construction system can for instance be used for indicating and / or being able to read a position of an upper side of a layer of bricks to be bricked when bricking a wall. In this case, with a construction system placed upright with respect to the wall, the distance markers are preferably at a distance corresponding to a desired height of a layer of bricks and associated cement, for example substantially 80 mm.

In the examples, the inner work, at least in the assembled state, is entirely included within the outer work. It is also possible that, in the assembled state, the inner work is received substantially within the outer work, whereby parts, for example protrusions, of the inner work extend through the outer work, for example through openings of the outer work.

In the examples, at least in the assembled state, the inner work abuts the outer work along at least four lines which extend substantially in the longitudinal direction of the outer work. It is also possible for the inner work to be provided with recesses on parts abutting against the outer work, for instance for reducing the weight of the inner work, so that the inner work substantially abuts the outer work, at least in the assembled state.
