EXEMPLARY EMBODIMENT OF THE INVENTION

The terms "upper", "bottom", "left", right" and "top" used in the text are used based on the usual working state of the stick system profile when installed to other construction structure.
The integral construction stick system profile 1, according to the invention, has an I-beam cross-section comprising two hollow flanges 2, 3 connected with a web 4, which is an intermediate element between the flanges 2, 3. In general, the I-beam cross section looks like a vertical line with two perpendicular horizontal lines, located on the top and the bottom of the vertical line, which horizontal lines project both in left and right direction of the vertical line. In present invention it is to be accepted that the horizontal lines are represented from the hollow flanges 2, 3, which extend symmetrically in both sides (left and right) of the vertical line (the web 4 when arranged in vertical position). Said hollow flanges 2, 3 have axial through internal channels opened in their two opposite ends, and the integral construction stick system profile 1 has a first end and, opposite to the first end, a second end.
The channel in each of the flanges 2, 3 is at least partly cylindrical and the directrix of the cylinder is a circle. Alternatively, it can be another closed curve, made of different arcs or arcs and lines. Such shape allows different types of fixing means to be engaged in the channel, by connecting at least partly to the inner surface of the flanges 2, 3, having a cross section as closed curve.
One of the hollow flanges is configured to receive a fixing means 5 for attaching the integral construction stick system profile 1 directly or indirectly to other construction structure. Preferably the upper flange 2 is configured to receive the fixing means 5, but alternatively the bottom flange 3 can also be configured to receive fixing means 5. Alternatively, both hollow flanges 2, 3 can be configured to receive fixing means 5 for attaching the integral construction stick system profile 1 directly or indirectly to other construction structure. Indirect attachment means that another subsidiary element can be arranged between the integral construction stick system profile 1 and the other construction structure or element.
The hollow flanges 2, 3 can have a circular outer shape, as shown on figures 1a, 1b, 1c, 3g, 5a, 5b, 6a, 6b, 6c, 6d, 7, 8 and 9. Said shape optimizes the manufacturing process, and saves costs, as it uses the optimal necessary material for creating the flange, unlike rectangular flanges, wherein the edges require additional material. Further, circular outer shape allows easier connection with additional elements which to be fitted around the flanges 2, 3.
In alternative embodiment of the invention, the hollow flanges 2, 3 have a partially prismatic outer shape, as shown on figures 2a, 2b, 2c, 2d, 2e, 2f, 3a, 3b, 3c, 3d, 3e and 3f. In this embodiment, it is possible one or both hollow flanges 2, 3 to have fastening cuts or fastening grooves or fastening openings 12 for connecting to additional fasteners and/or splicers and details on its outer surface, as shown on figures 2d, 2e, 2f, 3c, 3d, 3e, 3f, 26 and 27. Thus, the stick system profile 1 allows many different details, elements and objects to be fastened to the outer surface of the flange, for example, supporting profiles, road signs, marketing signs, strengthening or thermal insulation elements, etc.
Preferably, the web 4 is rectangular, but other embodiments are also possible, such as triangular shape, parallelogram-shaped such as diamond-shaped, other quadrangular shape, or other polygonal shape.
The web 4 can be arranged perpendicular, parallel or at an angle relative to the flanges 2, 3.
Preferably, the web 4 at least one weight lightening and thermal conductivity reducing through perforation 6, as shown on figures 3b, 4a, 4b, 4c, 4d, 4e, 4f and 4g. The perforations 6 can be made in different numbers and shapes, for example a square, a circle, a triangle, or another shape, or a combination of shapes, in case of more than one perforation. Said perforation 6 is an opening, made by void of material from suitable place of the web 4, which makes the web 4 lighter, in order to be easier for fastening, and to reduce the weight of the stick system profile 1 and the kit comprising it. It further has a thermal insulating effect, thus reducing the thermal bridge between the elements arranged on the two opposite sides of the stick system profile 1. The thermal conductivity is reduced, in a way still preserving the structural and fire resistance of the stick system profile 1 and the system it is attached to. This is achieved due to the reduction of the cross-section of the body, through perforation 6. Further, the thermal insulating effect can be additionally enhanced using linear stainless-steel details which are fastened to the flanges as extension details.
Preferably, one of the hollow flanges, or alternatively both hollow flanges 2, 3, are internally threaded. This allows different fastening means 5 with outer thread to be engaged in the hollow flanges 2, 3, as shown on figures 6a, 6b, 6c, 6d and 7. If the internal surface of the flanges 2, 3 is not circular, but another closed curve, then the fastening means 5 engage partly with the thread of the closed curve, still providing fastening in the stick system profiles 1. For example, a bolt or a screw or a stud can be engaged in the internal thread of the flanges 2, 3. In this case, the internal thread of the flanges 2, 3 can be made either in the entire channel, or alternatively in the parts of the internal wall of the channel, which contact the fastening means 5.
It is also possible none of the flanges 2, 3 to be made with a thread, in which case the distance and position of the stick system profile 1 according to the other construction structure is determined, and then fixed using a screw penetrating transversally through the flanges 2, 3, or flattening, or by another suitable manner known in the state of the art.
In one embodiment of the invention, the web 4 has a trapezoidal shape, and one of the flanges is reduced to a sleeve, as shown on figures 6a, 6b, 6c and 6d. Such reduction of material provides weight lightening of the stick system profile, and is suitable for unloaded constructions. Fig. 6a shows a stick system profile 1 with trapezoidal web 4, wherein the upper flange 2 is reduced to a sleeve, and a fixing means 5 can be arranged in it, in order to fasten the stick system profile 1 to other construction structure. Adjusting bolt 8 is placed in the bottom flange 3 passing through the entire channel of the flange 3, wherein the head of the bolt 8 is arranged at the first end of the stick system profile 1, and the threaded body of the bolt 8 extends from the second end of the stick system profile 1. This way the stick system profile 1 can be fastened to another body, such as a supporting profile. Fig. 6b shows a stick system profile 1 with trapezoidal web 4, wherein the upper flange 2 is reduced to a sleeve, and a fixing means 5 can be arranged in it, in order to fasten the stick system profile 1 to other construction structure. The fixing means 5 protrudes through respective opening of a supporting plank, arranged on the first end of the stick system profile 1, wherein, after passing said opening, the fixing means 5 enters the other construction structure in a way to be fastened to it. Adjusting bolt 8 is placed in the bottom flange 3 as in the variant on fig. 6a. The protrusion of the bolt 8 extending from the second part of the stick system profile 1 is fastened to a holder for a supporting profile. The holder can be a plank, or a U-shaped holder, or with another suitable shape. Fig. 6c shows a stick system profile 1 such as on the fig. 6a, wherein the protrusion of the bolt 8 extending from the second part of the stick system profile 1 is fastened to another body, such as a flat holder for a supporting profile. Fig. 6d shows a stick system profile 1 such as on the fig. 6a and 6c, wherein the protrusion of the bolt 8 extending from the second part of the stick system profile 1 is fastened to another body, such as a U-shaped holder for a supporting profile.
In one embodiment of the invention, the integral construction stick system profile 1 is a cantilever beam for supporting substructure, as shown on figures 8 and 9, wherein at least one of the hollow flanges 2, 3 is configured to receive fastening means 5 for connecting to an element of the supporting substructure, such as a holder for horizontal or vertical supporting profiles of supporting substructure, or directly to supporting profiles of supporting substructure.
All parts of the integral construction stick system profile 1 - the flanges 2, 3 and the web 4, can be made in different sizes according to the target use purpose, for example the channel of the flanges 2, 3, the size of the flanges 2, 3 (length and width), the size of the web 4 (length and width), and thickness of the web 4 can vary.
The flanges 2, 3 and the web 4 can be made of different materials, such as aluminium, stainless steel or another suitable metal. Also, plastic or ceramics can be used as material to make the flanges 2, 3 and the web 4.
Additional task of the invention is to create a stick system profile assembly kit with enhanced multifunctionality in its use, which is not limited to only supporting the element, it is attached to.
This task is solved by the stick system profile assembly kit, according to the invention, which comprises fixing means 5 and an integral construction stick system profile 1 according to the invention.
The fixing means 5 are placed in one of the flanges of the integral construction stick system profile 1, thus to allow attaching the integral construction stick system profile directly or indirectly to the other construction structure. Alternatively, second fixing means can be inserted in the second flange to additionally attach the integral construction stick system profile 1 directly or indirectly to the other construction structure.
In a preferred embodiment of the invention, which is not shown on the figures, a steel element, reducing the thermal bridge between the integral construction stick system profile and the other construction structure, is arranged in one of the flanges 2, 3. Alternatively, two steel elements can be arranged in the two flanges 2, 3, one steel element in each of them. Examples of such steel elements are tubes, dense cylinders, screws, dense rods with different shapes, or other suitable elements known in the state of the art.
In one embodiment of the kit according to the invention, at least one strengthening or elongating profile 7 is connected to one of the flanges 2, 3, which flange is configured to be fixed to the other construction structure. Said profile 7 can be attached longitudinally or transversely to the elongation of the flanges 2, 3. It is also possible to connect strengthening or elongating profiles 7 to the second flange too.
In one embodiment of the invention, fixing means 5 for attaching the integral construction stick system profile 1 directly or indirectly to other construction structures is positioned in the opening of one of the flanges at the first end and in the second flange is positioned adjusting means 8 for adjusting the distance between two other construction structures between which the integral construction stick system profile 1 is to be arranged. Such embodiments are shown on figures 6a, 6b, 6c and 6d, wherein the upper flange 2 is shortened to a sleeve in which the fixing means 5 will be inserted, and the bottom flange 3 are inserted adjusting means 8. Described construction allows adjusting the distance up to 80 mm. Said adjusting can be achieved by coiling and uncoiling the adjusting means 8 in the channel of the respective flange it is inserted in. Adjusting means 8 can be a bolt or a screw or a solid stud, or a tubular stud, or another suitable means.
In one embodiment of the invention, the stick system profile assembly kit further includes a supporting detail 9 configured to be positioned between the integral construction stick system profile 1 and the other construction structure, as shown on figures 5a, 5b, 6b, 8 and 9. Said supporting detail 9 has a through opening for receiving the fixing means 5 from the integral construction stick system profile 1 and at least one through opening for fixing the supporting detail 9 to the other construction structure by fastening means 5. An example of the supporting detail 1, as shown on figures 5a, 5b, 8 and 9, is a plank, which can be with trapezoidal or rectangular shape in cross section.
In another embodiment of the kit according to the invention, the stick system profile 1 includes fixing means 5 which is a chemical anchor. Said chemical anchor is coiled in one of the flanges 2, 3 and fixed by a suitable chemical compound, known in the state of the art, to a hole of the other construction structure.
For infilled building walls the stick system profile 1 is used as a beam detail can be attached to a wall using a channel rail as shown on figure 11, i.e., the fixing means 5 fasten the flanges 2, 3 to the channel rail. The channel rail is formed in horizontal direction in the surface of a supporting profile or another suitable object, known in the state of the art. The fastening means 5 engage in the channel of one of the flanges 2, 3 and enters into said channel rail, in which channel rail the fastening means 5 is fixed by means known in the state of the art, in a way to allow horizontal movement of the beam detail along the length of the channel rail.
In a preferred embodiment of the invention, the stick system profile assembly kit further includes a thermal insulation detail configured to be arranged on the side of the integral construction stick system profile 1 facing the other construction structure. Such thermal insulation detail can be, for example, an insulating washer, made of insulating material such as polymer, or made of reducing the thermal conductivity material, such as stainless steel, when the stick system profiles 1 is made of aluminium. This improves the thermal isolation properties of the stick system profile 1. It is also possible to use insulation plank as thermal insulation detail. Said insulation planks can be made of elastic or rigid material. If used rigid material, additional circumferential grooves can be made around through holes for receiving fixing means, such as bolts, anchors, studs.
In one embodiment of the invention, fixing means 5 for attaching the integral construction stick system profile 1 directly or indirectly to other construction structure is positioned in the opening of one of the flanges at the first end, and a levelling bolt 10 is arranged in the second flange at the same first end, as shown on figures 6a, 6c, 6d and 7. Fig. 7 discloses flanges 2, 3 with equal length, wherein the upper flange 2 receives fixing means 5, particularly a chemical anchor, and the bottom flange 3 receives a levelling bolt 10.
On the fixing means 5, outside the flanges 2, 3, a compensating washer 11 (not shown on the figures) may be arranged which thickness is proportional to the height of the head of the levelling bolt 10. The compensating washer 11 is inserted between the flange with the fixing means 5 and the other construction structure. It is also possible the compensating washer 11 to be missing, in which case the head of the levelling bolt 10 is dug into the flange. For levelling the integral construction stick system profile 1, the levelling bolt 10 is coiled or uncoiled, in order to compensate the unequal surface of the other construction structure, for example a wall. For example, levelling can be used if there is a protrusion on a wall with a hole for inserting an anchor. In this case, the compensating washer 11 of the anchor between the upper flange 2 (the flange with the anchor) and the wall compensates only the height of the head of the levelling bolt 10 inserted in the bottom flange 3. Since, in this case a cavity is formed between the bottom flange 3 and the wall, the levelling bolt 10 is uncoiled to compensate said cavity, when the stick system profile 1 is in horizontal position. Said construction enhances the levelling process, compared to the existing constructions, wherein additional inserts are fastened to the wall, which must be with different thickness and have openings for fastening by fastening means 5 to the wall, which required additional perforation of the wall for said fastening means 5. In a second example, when the hole for the anchor in the wall is located in a recess of the wall, the compensating washer 11 must be with height equal to the head of the levelling bolt 10 and the depth of the recess. Several washers 11, placed one on another, can also be used.
As shown on figure 10, the flanges 2, 3 of the stick system profile 1 can be subsequently flattened from one side of the stick system profile 1, or from the two sides of the stick system profile 1, to provide alternative possibilities for fixation to other construction structure, for example by inserting the flattened flanges 2, 3 in a holder and fixed by a screw or another suitable fastening means.
As shown on figures 12 - 23, the stick system profile 1 of the present invention can be used as beam details to build truss systems.
In case presented on figures 24 and 25, truss systems of the type of vierendeel truss systems can be assembled. These are beam (truss type) structures, which are mechanically assembled, without welding, and can be flat or spatial. Basically, they are made by a blank workpiece, which is cut lengthwise. The axis of the beam detail (stick system profile 1) is located between the two flanges along the length of the beam. The cut beams represent the ribs of a vierendeel truss system, which is installed as the ribs are fixed mechanically perpendicular to two parallel profiles. Fastening can be by rolling studs in the flanges 1, 2 of the beam details and in drilled holes in the parallel profiles 15, which are then tightened with nuts. Parallel profiles 15 can have different standard sections - square, rectangle, etc. In the case, shown on fig. 24 the axis of the beam details (ribs) are transverse to the axis of the truss system. In the case, shown on fig. 25 the axis of the beam details (ribs) are inclined to the axis of the truss system.
In case presented on figures 15-22, narrow pieces, shown on figures 12-14, of the hollow flanges 2, 3 are used as building blocks or braces to create the web of the assembled beam. Said narrow pieces are made by oblique or transverse cutting from a workpiece. Flat or volumetric trusses are obtained by assembling the cut elements on steel rods 14. It is possible flanges 2, 3 with parallel webs 4, shown for example on figure 14, to be assembled for creating a truss system. Also, it is possible the web 4 to be inclined to the flanges 2, 3 as shown on figures 12 and 13, thus forming a parallelogram-shaped web with angles other than 90 degrees, and with two bevelled angles. This can be manufactured, for example, by cutting an integral construction beam detail (stick system profile 1) with a wide web to slices, which are then strung on two steel rods 14 with their flanges 2,3.
In assembled truss system, end beam details (stick system profiles 1) always have webs 4 which are perpendicular to the steel rods 14.
The number of steel rods 14 is two if a flat truss system will be assembled, or three if a triangular truss system will be assembled, or four if quadrangular truss system will be assembled, etc.
Thus, flat beam details (stick system profiles 1) can be assembled in a long chain as shown on figure 23, wherein the steel rods 14 are axis of the chain, and the beam details are the chain links. Also, flat beam details can be assembled in a fence, wherein the steel 14 rods are poles of the fence, and the beam details are the net.
Also, it is possible the flanges to be offset from each other, wherein there are three interconnected beam details (stick system profiles 1), according to the invention. Such offset means that in cross section, flanges don't lie in the same longitudinal axis. Respectively one of the flanges 2, 3 is placed in one of the halves of the beam detail - left or right, and the second flange is placed on the other half of the beam detail. The flanges 2, 3 of the beam details are not closely spaced, but meet on the steel bar only where the beams touch each other.
In further embodiment of the invention, separate beam details (stick system profiles 1) are cut from a blank workpiece, and said pieces can be used as building blocks having flat or special beams and web, wherein the building blocks can be placed transversally, diagonally or longitudinally with respect to the chords/axis of the assembled beam/truss system.
For all embodiments of truss systems, after assembling the beam details (stick system profiles 1) on a steel rod 14, an external profile 13, for example a slitted pipe, is fitted around the flanges. Said slitted pipe 13 provides additional enforcement of the system, and protects the connections of the flanges 2, 3 and the steel rods 14.
Besides installed truss systems on steel rods, there are options to use structural beam details (stick system profiles 1), according to present invention, with grooved flanges, shown on figures 26 and 27. The installation of such truss systems are carried out by inserting external profiles 13 into the channels of the flanges. Grooved flanges can be used for assembly of flat truss systems. For volumetric truss system are used internal steel rods 14 or external profiles 13 with inclined feathers that enter into grooves of the flanges 2, 3.
Stick system profiles 1 can be used to form spatial structures, as shown on figures 28 and 29. To build such structures, a stick system profile 1 can be cut in a way that allows the assembly of the stick system profiles 1 to be carried out with the help of rods 14 or external profiles 13 that go inside or cover the configuration of the flanges 2, 3 themselves. The assembly of spatial structures can be done with the help of internal rods 14 in the flanges of the stick system profiles 1 or with the help of external profiles (slitted pipe or profile with inclined feathers that enter into grooves in the flanges 2, 3, as shown on figure 28). External profiles can also be used as reinforcing profiles if necessary. Spatial structures with a stick system profile 1 can use a combination of both internal rods 14 and external assembly profiles. The very configuration of the flanges 2, 3 of the stick system profile 1 has a sign of systematicity, i.e., the stick system profile 1 is assembled using a rod 14 or other external profile 13, but not a connecting piece or node.
Example for external profiles 13 are slitted pipes with different shapes in cross section, for example a square as shown on figure 28, or a circle as shown on figures 21 and 22, or another suitable shape.
