Description

  TECHNICAL FIELD The present invention relates to a profile rail, a fixing system for mounting a solar module on a trapezoidal thin plate, an assembly for fixing the solar module on a trapezoidal thin plate, and a method for mounting the fixing system according to the present invention on a trapezoidal thin plate. .

  A solar module, for example, a solar power generation module that generates electric energy or a heat collection module that heats a heat transfer medium, is generally fixed on deformed material rails arranged in parallel to each other when installed on a rooftop or outdoors.

  For roofs of industrial buildings and enterprise buildings, a trapezoidal thin plate or a folded plate is often used. This is because the trapezoidal thin plate has a considerably higher strength than a flat roof based on the given shape. As is well known, the trapezoidal thin plate has a peak portion and a side surface adjacent to the continuous metal thin plate. The side surface protrudes from a trough of a thin plate having a trapezoidal cross section.

  Known fixing systems are adapted to fix the profile rails on the ridges of a thin plate with a trapezoidal cross section. With this known fixed configuration, based on typical material thicknesses from about 0.5 mm, if the air suction load is too strong, the screws or rivets can be pulled out.

  A known fastening system for mounting a solar module on a thin plate with a trapezoidal cross section is provided by Schletter GmbH under the name VarioFix-V-System. This known fastening system uses a profile rail with a C-shaped inner profile on the underside. For attachment, a holder having a rectangular body and a T-shaped part is used. The T-shaped portion protrudes in the same plane at the center of the long side of the rectangle. The holder is inserted into the C-shaped inner contour at each T-shaped portion, and is fixed to the side surface of the thin plate having a trapezoidal cross section by fixing means such as screws or rivets inserted through the two through holes. In that case, the holder is completely under the profile rail. Mounting such a system is cumbersome because the holder must be inserted from below into the already mounted profile rail.

  It is demanded that a solar module can be mounted on a thin plate having a trapezoidal cross section more easily.

A first aspect of the present invention is a profile rail, which is seen in a cross-sectional view,
A bottom plate forming a partially or totally flat bottom surface of the profile rail;
First and second storage chambers for the rail holder, both of which are partially closed outwardly toward the sides, each having one lateral opening accordingly, The openings on both sides are first and second storage chambers oriented in opposite directions, and
A third storage chamber having an opening opposite to the lower surface of the profile rail, the opening having an inner contour for fixing the module fixing element;
It relates to a profile rail provided with.

  The profile rail according to the invention enables a particularly simple installation of a fixing system for solar modules on a thin plate of trapezoidal cross section. The rail holder is attached to the side surface of the peak portion of the thin plate at the side of the profile rail, and can be coupled to the profile rail in both storage chambers provided for the installation. In addition, the profile rails can be fixed on a sheet that allows expansion or contraction during temperature fluctuations.

  Based on the above-mentioned characteristics, the profile rail is simply mounted on the side surface of the ridge of the thin plate with a rail holder that can be engaged from the side in a storage chamber provided for mounting, and screws, rivets, etc. The fixing means can be attached so as to be coupled to the respective side surfaces. Thereby, the thin plate is loaded by shearing. Thus, compared to the case where the profile rail is screwed only from above and only a tensile load is applied to the thin plate, a much larger force can be applied to the thin plate, thereby withstanding a higher load. be able to.

  The holder is preferably fixed to the side surface so as to be located only in the upper third of the side surface of the peak when, for example, a thin plate having a general trapezoidal cross section is used. Thereby, it is not necessary to make a hole directly in the valley part which guides water.

  The profile rail according to the present invention enables use in different cross-sectional geometries of thin sheets. This is important for the variable use of profile rails based on the diversity of the thin plates.

  Both the first and second storage chambers for the rail holder are each partially closed outwardly toward the side. Accordingly, the storage chamber has one lateral opening that is open to the periphery of the profile rail. In this case, the term “side” should be understood as a direction that is transverse to the longitudinal direction of the rail and is not perpendicular to the bottom plate within the scope of the present invention.

  Below, the aspect of a deformed material rail is demonstrated.

  The bottom plate of the profile rail preferably has a generally flat lower surface. This allows for even placement on the ridges of the thin plate. However, the bottom plate is only partially if, for example, it is desirable that the recess is formed in the bottom plate for manufacturing and transport reasons, or if the recess is desired to be used to secure the profile rail. It may be flat. The bottom surface of the bottom plate also defines the bottom surface of the profile rail.

  In one aspect, the inside of the storage chamber for the rail holder is defined in a C shape. In other words, as viewed in the cross-sectional view, the sides defining the inner surface form a C-shape. Such a C-shaped definition can suitably be achieved by three sides. Of the three sides, relative to the bottom plate extending in the horizontal direction, two sides are also arranged in the horizontal direction, and one side is arranged in the vertical direction. When these sides meet at right angles to each other, a particularly simple, compact and stable embodiment results.

  The C-shape, partially closed towards the outside, makes it possible to use a rail holder having a T-shaped profile that complementarily engages. Such a rail holder enables a particularly stable and well adjustable adjustment by engaging from the side in the opening of the receiving chamber. This will be described in further detail below.

  However, alternatively, the C-shaped definition of the first or second storage chamber may be formed by sides intersecting at an angle different from a right angle or may be formed in an arc shape. Again, at least a portion of the C-shaped definition is at least virtually assigned to the typical stroke of the alphabet “C” described in its simplest form. The form in which the alphabet “C” is described in the simplest form has two horizontal bars and one vertical bar. In different aspects of the C-shaped definition, the transition between each section corresponding to each bar of the alphabet “C” may not be obvious.

  The opening of the storage chamber for the rail holder can be defined, for example, by a side protrusion.

  In one of the two alternative embodiments, only one side protrusion is used. A particularly simple embodiment is realized when such side protrusions are arranged on the bottom plate perpendicular to the bottom plate. Such side protrusions are formed, for example, by U-shaped coupling means forming a shape connection with the side protrusions, and the lower surface of the profile rail is formed by a thin plate. It makes it possible to apply a pressing force to the substrate. Such a force can hold the profile rail on the substrate. Furthermore, it is possible to prevent the profile rail from sliding sideways due to the shape coupling.

  In a variation of this first alternative aspect, only the upper side projections serve to partially close the receiving chamber for the rail holder outwards laterally. The storage chamber formed in this way can form a shape connection together with, for example, an S-shaped connection means of a rail holder, thus holding the deformed material rail on the base material and preventing sliding and tilting. At this time, preferably, the upper side protrusions are also arranged perpendicular to the bottom plate.

  Preferably, in the other of the two alternative aspects, the opening of the storage chamber for the rail holder includes a lower side protrusion, a variation of the first alternative aspect, and And the upper side protrusion as described above. The side protrusions of the respective storage chambers are preferably positioned perpendicular to the bottom plate, and are arranged on an extension line. This produces a particularly simple embodiment in terms of structure. This aspect is particularly compact with respect to its outer dimensions. Furthermore, stabilization in the longitudinal direction is achieved by the combination of the elements of the profile rails situated perpendicular to each other. The configuration of the upper and lower side protrusions at the opening of the storage chamber for the rail holder is also particularly suitable for receiving the T-shaped coupling means of the rail holder and forming the shape coupling portion. Has the advantage. At that time, the T-shaped horizontal bar portion of the T-shaped coupling means engages with the lower side protrusion piece and the upper side protrusion piece. Thereby, the profile rail is additionally stabilized, in particular against tilting.

  Each side opening of the storage chamber of the profile rail according to the first aspect of the present invention is directed in the opposite direction. Here, the reverse direction is understood to be a direction different from 90 °. Particularly preferably, the directions are greater than 120 °, more preferably approximately 180 ° or just 180 ° different. This ensures that the openings are suitable for allowing the T-shaped part of the rail holder to be introduced into the profile rail from the sides respectively. The direction in which the opening of the containment chamber is oriented is perpendicular to the surface between the elements defining the opening, for example, the ends of the side projections, in accordance with common language conventions. Pointing away from the chamber.

  According to a particularly preferable aspect, the second storage chamber is formed mirror-symmetrically with respect to the first storage chamber with respect to a virtual central plane positioned perpendicular to the bottom plate. This allows a particularly simple and compact construction of the profile rail.

  By the way, the side openings of the first and second storage chambers need not be the only openings of these storage chambers. Rather, another opening may be provided, for example, an opening for leading rainwater.

  Depending on the arrangement of the third storage chamber, the structural form of the profile rail can be formed so that the lateral width is narrowed or widened.

  The third storage chamber may be formed between the first storage chamber and the second storage chamber for the rail holder. This allows for a wider structural form of the profile rail. Alternatively, however, the third storage chamber may be formed above the first and second storage chambers. This allows a relatively narrow structural form of the profile rail. In this configuration, the first and second storage chambers can be arranged close to each other. However, the third storage chamber may be formed only partially above the first and second storage chambers and only partially between the first storage chamber and the second storage chamber. Is possible. This makes it possible, for example, to provide a stabilizing structure below the third storage chamber.

  The third storage chamber has an inner contour that serves to fix the module fixing element. In this case, the module fixing element is generally understood to be an element that serves to achieve a stationary or strong connection between the profile rail and the solar module.

  The inner contour may be formed in different forms. For example, two opposing protruding pieces may be disposed on the side of the third storage chamber opposite to the bottom plate. Two opposing protrusions allow the T-shaped part or groove block to form a shape bond with it. Such a configuration corresponds to a configuration in which the orientation of the configuration of the first or second storage chamber provided with the upper and lower side protrusions as described above is changed by 90 °. However, the present invention is not limited to this configuration, but rather any inner contour that allows the fixing of a component, for example a solar module, to the profile rail can be used. Another preferred embodiment is described further below.

  In a preferred aspect, the inner contour has a bent portion that extends substantially in parallel with the bottom plate on each of different walls or protrusions, and the first bent portion of the bent portions is a second bent portion. In comparison, it has a greater spacing from the bottom plate and the inner contour has first and second mounting surfaces for the fixing element, and the first and second mounting surfaces and The distance from the bottom plate is smaller than the distance between the first bent portion and the bottom plate. In such an aspect, by arranging the two bent portions at different distances from the bottom plate, the first assembly in the assembled state is used in the coupling block (Verbinungstain) used for fixing the solar module on the deformed material rail. Or the 1st and 2nd engagement surface engaged with a 2nd bending part does not need to be located in one plane. This allows a particularly simple loading of the connecting block into the profile rail by light tilting. The first and second mounting surfaces remain in a state where the coupling block is first positioned on both of the mounting surfaces after insertion, and can prevent dropping, tilting and rotation. In this way, at the time of assembly, a series of connecting blocks can first be inserted into the respective profile rails before being used for fixing the solar module. Since it is desirable that the coupling block is first mounted on the first and second mounting surfaces and then crimped to both bent portions by an upward force, the first and second mounting surfaces and the bottom plate The distance needs to be smaller than at least the distance between the first bent portion and the bottom plate of both bent portions.

  Particularly preferably, the first placement surface and the second placement surface are parallel to the bottom plate. Furthermore, the first placement surface and the second placement surface are preferably arranged at equal intervals from the bottom plate. This facilitates the placement of the connecting block having a flat lower surface.

  In one aspect, the first bent portion and the first placement surface at least partially overlap. In another aspect, the second bent portion and the second placement surface at least partially overlap. Both of these aspects may of course be combined with each other.

  In a particularly preferred embodiment, the inner contour has a projecting piece protruding from the plane of the bottom plate, the projecting piece being arranged between the two inner walls of the profile rail located opposite each other, from the bottom plate A second bend is provided at the distal end. Further, the first bent portion is disposed on one first inner wall of the inner walls, and is oriented in the same direction as the second bent portion. Such a configuration of the inner contour allows the use of a U-shaped connecting block. In this case, the coupling block may have a first engagement surface that engages with the first bent portion under the action of an upward force. Furthermore, the coupling block may have a second engagement surface that engages with the second bent portion under the action of an upward force. The second engagement surface of the coupling block exists on the upper surface of a side different from the side where the first engagement surface exists.

  Preferably, the protruding piece is erected vertically to the bottom plate. This allows for a particularly simple longitudinal stabilization.

  In a preferred embodiment, the first placement surface protrudes from the first inner wall. Thereby, the 1st bending part and the 1st mounting surface at least partially overlap. As a result, the clearance of the connecting block after charging and before fixing is limited on both sides along the first inner wall.

  In another preferred embodiment, the second mounting surface is disposed at an end of the protruding piece that is distal from the bottom plate. Thereby, the projecting piece not only has a role of holding the second bent portion at a desired position, but also forms a second mounting surface at the same time. Thereby, another element which provides a 2nd mounting surface is omissible. In exactly this manner, it is particularly advantageous if the first mounting surface and the second mounting surface have the same spacing from the bottom plate. That is, a flat and flat mounting of a connecting block having a flat mounting surface is possible.

  In an alternative embodiment, the inner contour is formed such that a simple groove block can be inserted and fixed. In another alternative aspect, the inner contour is formed such that a hex nut can be inserted and secured from the side.

A second aspect of the present invention is a fixing system for mounting a solar module on a thin plate having a trapezoidal cross section having a peak and a side surface corresponding to the peak.
At least one profile rail according to the first aspect of the invention;
A plurality of rail holders;
Each of the rail holders,
The body,
A first through hole penetrating the body;
A T-shaped part protruding from the body;
The deformed material rail is fixed by the rail holder so that the T-shaped portion is engaged with the side opening provided in the first storage chamber or the second storage chamber, and the through-hole is penetrated. By fixing the rail holder to the side surface by means, it can be fixed on the peak part,
The upper surface of the main body of the rail holder does not protrude from the upper surface of the deformed material rail in the assembled state.
Regarding the fixing system.

  Such a fixing system comprises a combination according to the invention of a profile rail and a rail holder corresponding to the profile rail. The holder can be easily connected to the profile rail by means of a T-shaped part protruding from the body. For this purpose, the T-shaped part is inserted into the first storage chamber or the second storage chamber for the rail holder of the profile rail and is rotated appropriately. Furthermore, the rail holder can be fixed to one side surface of each of the thin plates having a trapezoidal cross section by the respective through holes of the rail holder. For this purpose, the body inserts a T-shaped part into one of the openings on both sides of the profile rail and rotates the T-shaped part in the respective first or second storage chamber for the rail holder. Even after it is moved, it can continue to move freely in the longitudinal direction, and can continue to rotate, and is preferably brought into surface contact with the side surface of the thin plate. For fixing, typical elements such as screws or rivets are suitable. These elements are inserted into the through holes and pushed into the material of the sheet. As a result, a strong and unbonded bond can be formed between the rail holder and the thin plate. As already described above, by such a strong coupling using the shape coupling of the profile rail and the rail holder, the profile rail is also firmly held on the thin plate, and sliding and tilting can be prevented.

  It should be noted that the upper surface of the rail holder of the fixing system does not protrude from the upper surface of the profile rail in the assembled state in the present invention. This makes it possible to attach the rail holder to the profile rail from the side and to place the solar module flat on the profile rail.

A third aspect of the present invention is an assembly for fixing a solar module,
A fixing system according to a second aspect;
A thin plate with a trapezoidal cross section having a peak and a side surface corresponding to the peak,
The profile rail is mounted on the mountain,
The rail holder is fixed to the side surface of the peak portion of the thin plate by fixing means penetrating the through hole of the rail holder, and the T-shaped portion of the rail holder is provided in the first accommodating chamber of the deformed material rail, respectively. Engaged in a lateral opening provided or in a lateral opening provided in the second storage chamber,
The present invention relates to an assembly for fixing a solar module.

  Thereby, the assembly which concerns on the 3rd viewpoint of this invention is related with the combination of the fixing system which concerns on the 2nd viewpoint of the assembled state, and the cross-sectional trapezoid thin plate. In doing so, as already explained in connection with the fastening system, the body of the rail holder is preferably in surface contact with the respective side of the sheet and is connected to the profile rail via the T-shaped part of the rail holder. Form. In that case, the rail holder is located on the side of the profile rail. The profile rail is thus firmly held on the peak of the thin plate. Thereby, the thin plate and the profile rail form a tightly coupled unit.

  Preferably, a planar spacer is assembled between the thin plate and the profile rail. The spacer can be made, for example, from ethylene-propylene-diene-rubber (EPDM). Ethylene-propylene-diene-rubber has advantageous properties for this type of use. Contact corrosion between materials can be prevented by the spacer.

  As already implied in connection with the profile rail according to the present invention, the assembly according to the third aspect of the present invention is such that a relatively large force is applied to the thin plate, so that it can withstand higher loads. Excellent (shear load). The holding according to the invention of the profile rail makes it possible to tolerate length changes due to the temperature of the material.

  When assembling the rail holder, the assembly according to the invention allows a particularly high flexibility. Based on static loads, the number of rail holders can be significantly reduced. The rail holder can be attached to the side surfaces of all the valleys, but may be attached to every other valley or every other valley, for example. This not only optimizes the load on the sheet, as already mentioned.

  In one aspect of the assembly, the rail holder for each profile rail is accordingly attached only to one side of the profile rail. This means that the rail holder is not attached to one of the first and second storage chambers for the rail holder. Based on the structure of the storage chamber and the rail holder, this can in principle also be sufficient for secure mounting of the profile rail.

  Preferably, however, the rail holders are attached to both sides of the profile rail. As a result, a corresponding holding action occurs on both sides of the profile rail. This achieves a particularly favorable distribution of the forces acting on the sheet.

  The rail holder may be attached so that a compressive load and a tensile load are alternately exerted on the thin plate. For this purpose, when the rail holder is mounted, the upper portion of the storage chamber is defined before being fixed to the respective side surface by the fixing means as long as each T-shaped portion has a clearance in the respective storage chamber. It must be held against the surface or the lower defining surface. If the sheet has height irregularities, one rail holder may nevertheless be attached to each side.

  In principle, it is not necessary to install rail holders on all sides. For example, the rail holders may be attached to the side surfaces of every other, every second, every third, and so on. Moreover, the rail holder may be arrange | positioned at each side of the deformed material rail alternately, for example.

  In addition to the rail holder, an upper trapezoidal holder may be mounted on the peak portion. The trapezoidal holder additionally holds the profile rail. The trapezoidal holder can be suitably used, for example, when the suction load is strong or when the valley depth of the trapezoidal thin plate is not sufficient. This type of upper trapezoidal holder has, for example, a mounting plate having a through hole, and can be fixed on the mountain portion. Further, the upper trapezoidal holder has a C-shaped holding portion, for example. The C-shaped holding portion engages in the storage chamber of the profile rail. This can achieve additional holding of the profile rail.

A fourth aspect of the present invention is a method of attaching a fixing system according to the second aspect on a thin plate having a trapezoidal cross section having a ridge and a side surface corresponding to the ridge,
a) placing the profile rail on the bottom of the thin plate on the bottom surface of the profile rail;
b) inserting the T-shaped part of one rail holder into one of the storage chambers for the profile rail;
c) fixing the rail holder to one of the side surfaces by a fixing means inserted through the through hole of the rail holder;
d) a step of repeating steps b) and c) at least once each time in another rail holder;
To a fixing system on a thin plate with a trapezoidal section.

  The method according to the fourth aspect of the present invention allows easy attachment of the profile rails belonging to the fastening system according to the second aspect with the corresponding rail holder. In that case, the rail holder can be mounted on one side or preferably on both sides of the profile rail.

  By the method according to the fourth aspect of the present invention, the fixing system and the trapezoidal thin plate according to the second aspect are transferred to the assembly according to the third aspect of the present invention. At that time, the already described change modes and advantages are also realized in the method according to the fourth aspect of the present invention.

  By placing the profile rails loosely on the flat roof at the start of the method and then fixing each rail holder to the appropriate side for the first time, the method according to the fourth aspect provides the maximum flexibility. Have the ability. As many rail holders as needed for a profile rail can be mounted, and their position is almost freely selectable. Since the rail holder is attached from the side, the place where the work process must be performed is easily accessible.

  In order to fix the position of the holder, i.e. to avoid sliding down of the rail holder, a screw may be fixed at the end of the rail, in the immediate vicinity of the last rail holder, by a nut fitted in the receiving chamber. This allows the rail to move freely during thermal expansion but does not slide down.

  By means of the profile rail, the fixing system, the assembly and the method according to the invention, the solar module can be fixed to a continuously extending rail both in the form of dots and rows.

  FIG. 1 is a cross-sectional view of a first embodiment of a profile rail 1000 according to the first aspect of the present invention. The profile rail 1000 has a bottom plate 1100. The lower surface of the bottom plate 1100 forms a lower surface 1110 of the profile rail 1000. Since the lower surface 1110 has the recess 1120, it is only partially flat. The lower surface 1110 forms a mounting surface for the deformed material rail 1000 within a flat range. The deformed material rail 1000 is placed through this placement surface in the assembled state.

  The profile rail 1000 has a first storage chamber 1200 for the rail holder above the bottom plate 1100. The first storage chamber 1200 is partially closed toward the left side as viewed in FIG. For this purpose, the side protrusions 1220, 1230 are useful. A side opening 1210 is formed between the side protrusions 1220 and 1230. Aside from the opening 1210 and the side protrusions 1220 and 1230, the first storage chamber 1200 is defined in a C shape. This definition is made up of two horizontal pieces or horizontal pieces 1240 and 1260 and one vertical piece or vertical piece 1250, which corresponds to a C-shaped horizontal bar. The direction piece 1250 corresponds to a C-shaped vertical bar.

  There is a second storage chamber 1300 for the rail holder that is mirror-symmetric with respect to the first storage chamber 1200 for the rail holder. The second storage chamber 1300 is partially closed by two side protrusions 1320 and 1330 toward the right side as viewed in FIG. Similar to the first storage chamber 1200, a side opening 1310 is formed between the side protrusions 1320 and 1330 of the second storage chamber 1300. The second storage chamber 1300 is also defined in a C shape by two horizontal pieces or horizontal pieces 1340 and 1360 and one vertical piece or vertical piece 1350.

  Further, the profile rail 1000 has a third storage chamber 1400. The third storage chamber 1400 also exists above the bottom plate 1100, and further exists above the first and second storage chambers 1200 and 1300. The third storage chamber 1400 has an inner contour 1500. The inner contour 1500 is formed from two lateral protrusions 1510 and 1520. An opening 1410 opposite to the lower surface 1110 of the deformed material rail 1000 is formed between the lateral protrusions 1510 and 1520 arranged at equal intervals from the bottom plate 1100. As can be seen in FIG. 1, the opening 1410 faces upward when the profile rail 1000 is mounted with its lower surface 1110 down.

  The first and second receiving chambers 1200 and 1300 for the rail holder serve to receive an appropriate coupling means for the rail holder when the profile rail 1000 is mounted on a thin plate or a folded plate having a trapezoidal cross section. In particular, the use of T-shaped and U-shaped coupling means is conceivable. Thereby, shape coupling | bonding can be formed between the deformed material rail 1000 and each rail holder. Next, when the rail holder is coupled to the above-described thin plate, a shape coupling is also formed between the profile rail 1000 and the thin plate. Due to the shape connection, the profile rail 1000 is held on a thin plate.

  In the third storage chamber 1400, a suitable coupling means for module fixing elements or the entire module fixing element can be stored. As described above, since the third storage chamber 1400 is defined by the lateral protrusions 1510 and 1520, if the coupling means is appropriately formed, a shape coupling is formed between the module fixing element and the profile rail 1000. Is done. On the other hand, a solar module such as a solar power generation module or a solar heat collection module can be fixed to the module fixing element. The solar module is thus mounted on a thin plate.

  FIG. 2 shows a second embodiment of the profile rail 2000 according to the first aspect of the present invention. The profile rail 2000 has a bottom plate 2100. The bottom plate 2100 forms a generally flat lower surface 2110 of the profile rail 2000. First and second storage chambers 2200 and 2300 for the rail holder are formed on the side of the deformed material rail 2000, similarly to the deformed material rail 1000 shown in FIG. The first and second storage chambers 2200 and 2300 are defined by side protrusions 2220 and 2230 and 2320 and 2330, respectively, toward the outside. Side openings 2210 and 2310 are formed between the side protrusions 2220 and 2230 and 2320 and 2330, respectively. The first and second storage chambers 2200, 2300 for the rail holder are also defined in a C shape, apart from the side protrusions 2220, 2230, 2320, 2330 and the openings 2200, 2300.

  Further, the profile rail 2000 has a third storage chamber 2400. The third storage chamber 2400 forms an opening 2410 opposite to the lower surface 2110 of the profile rail 2000. The third storage chamber 2400 is defined by a first inner wall 2420 and a second inner wall 2430 on the side, and is defined by a bottom plate 2100 on the lower side.

  An inner contour 2500 is formed in the third storage chamber 2400. The inner contour 2500 includes a first bent portion 2510, a first placement surface 2530, and a projecting piece 2550 having a second bent portion 2520 and a second placement surface 2540. Both the first bent portion 2510 and the first placement surface 2530 protrude from the first inner wall 2420. At that time, the first bent portion 2510 is located more distally from the bottom plate 2100 than the first placement surface 2530. Furthermore, the first placement surface 2530 protrudes into the third storage chamber 2400 larger than the first bent portion 2510. A second bent portion 2520 and a second placement surface 2540 are disposed at the end of the protruding piece 2550 distal to the bottom plate 2100. At that time, the second bent portion 2520 protrudes in a direction away from the first inner wall 2420, similarly to the first bent portion 2510. The second placement surface 2540 is spaced from the bottom plate 2100 by the same distance as the first placement surface 2530. The web 2550 is erected vertically on the bottom plate 2100.

  The functions of the first and second receiving chambers 2200 and 2300 for the lower surface 2110 and the rail holder are the same as those of the lower surface 1110 of the profile rail 1000 shown in FIG. 1 and the first and second receiving chambers 1200 for the rail holder. , 1300. Therefore, the re-explanation here is abbreviate | omitted.

  The inner contour 2500 makes it possible to form a shape connection with a suitable connection block. Details of this will be described below with reference to FIG.

  FIG. 3 shows the profile rail 2000 shown in FIG. 2 with the coupling block 3000 inserted. The coupling block 3000 has a placement surface 3100 and is formed in a U-shape on one side. Thus, the coupling block 3000 has the first engagement surface 3300 on the upper surface thereof and the engagement surface 3400 on the upper surface of the lower side of the U shape. A hole 3200 extends through the coupling block 3000. Through the hole 3200, the coupling block 3000 can be coupled to an element disposed above the profile rail 2000 by screws. Examples of such elements are other profile rails, solar modules such as photovoltaic modules or solar heat collection modules, or spacers.

  In order to attach the coupling block 3000, the coupling block 3000 is first mounted on the first mounting surface 2530 and the second mounting surface 2540 of the deformed material rail 2000 with the mounting surface 3100. This makes it possible to load a plurality of connecting blocks after mounting the profile rail on a thin plate with a trapezoidal cross section. The possibility of tilting, turning or dropping the coupling block is eliminated. When an upward force is exerted on the coupling block 3000 via a screw inserted into the hole 3200, the coupling block 3000 is pulled upward away from the bottom plate 2100. Thereby, the first engagement surface 3300 is engaged with the first bent portion 2510, and the second engagement surface 3400 is also engaged with the second bent portion 2520. As a result, since the coupling block 3000 is hooked on the deformed material rail 2000, it is possible to fix the elements arranged above the deformed material rail 2000 by the bonding across the space (raumschurge Verbundung). Overall, the combination of the profile rail 2000 and the coupling block 3000 achieves a particularly simple assembly of the elements arranged above the profile rail 2000.

  FIG. 4 shows a rail holder 4000 for a fastening system according to the second aspect of the present invention. The rail holder 4000 has a main body 4100. The main body 4100 has a vertically long shape. A T-shaped portion 4200 is provided in the vicinity of one end. The T-shaped portion 4200 has a T-shaped horizontal bar portion 4220 and an attachment portion 4210. At this time, the horizontal bar portion 4220 is formed in parallel to the main body 4100 and is coupled to the main body 4100 via the attachment portion 4210. Further, the main body 4100 has a protruding portion 4300. Two through holes 4310 and 4320 are formed in the protruding portion 4300. The rail holder 4000 has a constant thickness in a direction perpendicular to the plane shown in FIG.

  The T-shaped portion 4200 is shape-coupled to one of the accommodating chambers 1200, 1300, 2200, 2300 of the respective profile rails 1000, 2000 when the profile rails 1000, 2000 according to the first aspect of the present invention are attached. Help to form. To do this, first, the horizontal bar portion 4220 of the T-shaped portion 4200 must be arranged substantially parallel to the longitudinal extension of the respective side openings 1210, 1310, 2210, 2310. Next, the horizontal bar portion 4220 is introduced into the respective storage chambers through the openings. After the introduction, the rail holder 4000 is rotated around the attached portion 4210. As a result, a shape connection is formed between the rail holder 4000 and the deformed material rails 1000 and 2000, so that the rail holder 4000 is no longer removed unless the deformed material rail is rotated in the reverse direction. The pivoting is advantageously performed so that the body 4100 is mounted substantially flat on the side of the ridge in order to mount the respective profile rails on the trapezoidal section. Next, a suitable fixing means, for example, a screw or a rivet is inserted into one or both of the through holes 4310 and 4320 and pushed into the material of the thin plate. When the pressing is performed until the strong and non-sticky bond is formed between the rail holder 4000 and the thin plate, the profile rails 1000 and 2000 are also held on the thin plate by the rail holder 4000.

  FIG. 5 shows the deformed material rail 1000 according to the first embodiment as shown in FIG. 1 in a state where the rail holder 4000 is inserted and rotated. The horizontal bar portion 4220 of the T-shaped portion 4200 of the rail holder 4000 fitted in the second storage chamber 1300 of the profile rail 1000 forms a shape connection with the longitudinal piece 1350 and the side protrusions 1320 and 1330. You can clearly see what you are doing. Further, it can be seen that the horizontal bar portion 4220 has a clearance in the second storage chamber 1300 upward. This achieves compensation for unevenness of the constituent members used and tolerance for changes in length due to temperature. From the above-described shape coupling, it can be seen that the deformed material rail 1000 is finally fixed by fixing the rail holder 4000 to the side surface of the thin plate having a trapezoidal cross section.

  FIG. 6 shows an embodiment of a fixing system according to the third embodiment of the present invention. This fixing system has two profile rails 2000 and 12 rail holders 4000 according to the second embodiment. At that time, refer to FIG. 2 for the configuration of the profile rail 2000. For the configuration of the rail holder 4000, see FIG.

  The fastening system shown in FIG. 6 allows for the parallel mounting of two profile rails 2000 on a trapezoidal cross section. At this time, each of the two profile rails 2000 can be fixed to the thin plate by the six rail holders 4000. Such parallel mounting of two profile rails 2000 is typically used to mount a series of solar modules. At that time, each solar module is placed on each of the two profile rails. In so doing, the solar module is secured to the profile rail by means of suitable module securing elements that engage the profiled rail inner contours 1500, 2500.

  It should be noted that the fixing system according to the present invention is not limited to two profile rails and 12 rail holders. Rather, any other meaningful combination of profile rails and rail holders can also be used, which can be considered as a kit for mounting solar modules, for example.

  FIG. 7 shows an assembly 7000 for fixing a solar module comprising a fixing system according to a second aspect of the invention and a thin plate 7500 having a trapezoidal cross section.

  The thin plate 7500 has a trough 7510 and a crest 7540 positioned between two troughs 7510. Each mountain portion 7540 is provided with two side surfaces 7520 and 7530. Side surfaces 7520 and 7530 respectively connect adjacent valley portions 7510 and peak portions 7540. The valley portions 7510, the side surfaces 7520 and 7530, and the peak portions 7540 are formed by bending a single continuous metal thin plate.

  The deformed material rail 2000 is placed on the peak portion 7540 of the thin plate 7500 at the lower surface 2110 thereof. On both sides of the profile rail 2000, each rail holder 4000 is mounted such that the T-shaped portion of the respective rail holder 4000 forms a shape connection with the defined portion of the first or second storage chamber 2200, 2300. It has been. Furthermore, the rail holder 4000 is fixed to the respective side surfaces 7520 and 7530 by screws 7100. As a result, the deformed material rail 2000 is also held immovably on the thin plate 7500 by the medium of fixing to the deformed material rail 2000 already described with reference to FIG. By attaching the rail holders 4000 on both sides, additional stabilization of the profile rail on the peak is achieved.

  FIG. 8 shows a method of attaching a fixing system according to the second aspect of the present invention on a thin plate having a trapezoidal cross section. As shown in FIG. 7, the thin plate has a crest and a side surface corresponding to the crest.

  First, in step S81, the first profile rail belonging to the fixing system is placed on the peak portion of the thin plate with the lower surface thereof. Next, in step S82, the T-shaped portion of one rail holder belonging to the fixing system is inserted into one accommodating chamber of the deformed material rail. Next, in step S83, the rail holder is rotated so that the main body of the rail holder is placed on one of the side surfaces, and is fixed to the side surface with screws. In step S84, the rail holder insertion step S82 and the fixing step S83 are repeated many times until a sufficient number of rail holders are attached to hold the deformed rail on the peak portion.

  Next, in step S85, the second deformed material rail belonging to the fixing system is placed in parallel to the first deformed material rail. The second profile rail must be spaced from the first profile rail so that the desired module can be mounted and secured.

  Next, steps S82 to S84 are repeated for the second profile rail until the second profile rail is mounted on the thin plate with sufficient strength.

  In that case, it is not necessary to fix the second profile rail on the same side as the first profile rail. Rather, both profiles rails can be fixed independently of one another, depending on the requirements of the surrounding conditions, for example, compensation of irregularities, setting of expansion tolerances or the presence of obstacles on the sheet.
