Description

Technical Field

[0001] The present disclosure relates to a clip-on roof system and a method for assembling the clip-on roof system. The clip-on roof system is suitable, for example, for temporary installations, but may alternatively be used for more permanent buildings. The clip-on roof system is suitable, for example, as a weatherproofing member.

[0002] Furthermore, even though the card-slat roof system according to the present disclosure will be described primarily with respect to a roof, the card-slat roof system is not limited to this use, but may also be used for other purposes, such as side walls, privacy protection, etc. Background Art

[0003] The clips are attached to the fabric to form a continuous sealed connection between the fabric and the frame. The clips are used in a variety of applications including permanent tents and structures and semi-permanent tents and structures.

[0004] Clip-strip roof systems are known in the prior art. These known clip-strip roof systems usually have specially designed roof support beams with integrated clip grooves for installing a tarpaulin extending between two adjacent support beams.

[0005] The slat roof system includes a sheet of fabric or tarpaulin having a slat chord attached to the side edges of the fabric, and a slat groove may be provided in the support beam. After the slat chord is inserted into the slat groove, a continuous sealed connection is achieved between the fabric and the support beam. Slats are used in a variety of applications, including permanent tents and structures and semi-permanent tents and structures.

[0006] In known slat roof systems, the tarpaulin generally comprises a cavity into which a laterally extending elongated rod or a similar type of elongated rigid member can be inserted before the tarpaulin is installed. A traction rope is then fastened to the rod, which serves as a force transmission member between the traction rope and the tarpaulin during installation of the tarpaulin on the roof support beams. After assembly is complete, a slat roof assembler generally climbs onto the slat roof to remove the rod from the slat roof, thereby ensuring that the rod does not accidentally fall off during subsequent use of the slat roof.

[0007] These prior art clip-on roof designs generally work well, but there remains a continuing need for further improvements in performance, particularly in terms of cost-effectiveness and safety. Summary of the invention

[0008] A particular problem with the prior art clip-on roof system is that a special roof support beam with the required clip-on groove is required. Therefore, even if the user has obtained a conventional roof support beam without a clip-on groove, such as a lattice beam, the user must nevertheless obtain another roof support beam with the clip-on groove.

[0009] Furthermore, climbing onto an installed slatted roof to remove the poles may involve the risk of accidents such as falling persons or falling objects.

[0010] Therefore, there is a need to further improve the performance, in particular to further improve the performance in terms of cost efficiency and safety.

[0011] The object of the present disclosure is to provide a strip-type roof system that avoids the aforementioned problems. This object is achieved at least in part by the features of the independent claim. The dependent claims contain further improvements to the strip-type roof system.

[0012] According to a first aspect of the present disclosure, a card-strip roof system is provided, which includes: a first elongated track structure having a first card-strip groove; a first tarpaulin, the first tarpaulin being in a rectangular form with opposite first and second side edges, wherein the first tarpaulin has a first card-strip chord located along the first side edge and a second card-strip chord located along the second side edge, and wherein the first card-strip chord is configured to be inserted into the first card-strip groove of the first elongated track structure and can be slidably moved in the first card-strip groove of the first elongated track structure; a first shuttle device, the first A shuttle device is fastened to a first tarpaulin, wherein the first shuttle device has a rope attachment structure; a traction rope, which is configured to be attached to the rope attachment structure of the first shuttle device; wherein the first elongated track structure includes a rope guide structure, which is configured to hold and guide the traction rope along the first elongated track structure at a position outside the first clamping strip groove; and wherein the traction rope and a portion of the first shuttle device are configured to pass through the rope guide structure of the first elongated track structure when the first tarpaulin is being installed on the first elongated track structure.

[0013] According to a second aspect of the present disclosure, a method for assembling a clip-type roof system is provided, the method comprising providing the following: a first elongated track structure having a first clip groove and a rope guide structure; a first tarpaulin, the first tarpaulin being in a rectangular form with opposite first and second side edges, wherein the first tarpaulin has a first clip chord located along the first side edge and a second clip chord located along the second side edge; and a first shuttle device fastened to the first tarpaulin. The method further comprises: installing a traction rope in the traction rope guide structure of the first elongated track structure, and attaching the traction rope to the traction rope attachment structure of the first shuttle device; and assembling the first tarpaulin on the first elongated track structure by pulling the traction rope for slidingly installing the first clip chord in the first clip groove, while holding and guiding the traction rope along the first elongated track structure at a position outside the first clip groove by means of the rope guide structure, and simultaneously passing a portion of the first shuttle device through the rope guide structure of the first elongated track structure.

[0014] In this way, due to the fact that the first shuttle device is fastened to the first tarpaulin, the risk that the first shuttle device may accidentally fall off during use of the clip-on roof is eliminated, thereby also eliminating the need to climb onto the clip-on roof to remove the first shuttle device. Therefore, when the clip-on roof is removed, there is no need to climb onto the clip-on roof to reinstall the first shuttle device.

[0015] Furthermore, the traction rope guide structure of the first elongated track structure ensures that the traction rope is securely held in the correct position during the assembly of the roof support beams and during the subsequent installation of the awning on the support beams. Without such a traction rope guide structure of the first elongated track structure, the traction rope could easily be displaced from its proper position, thereby making the subsequent installation of the awning on the support beams more difficult or even impossible.

[0016] For example, the direction of the tension applied by the traction rope on the tarpaulin should preferably be more or less parallel to the direction of elongation of the clip groove at the position of the first shuttle device to ensure smooth and low-resistance sliding of the first clip chord in the first clip groove, and the traction rope guide structure of the first elongated track structure can be positioned to improve the said level of parallelism.

[0017] This is particularly relevant in the case where the tarpaulin is mounted on the underside of the roof support beams, since such mounting would prevent the use of the laterally extending roof ridge beams for guiding the traction ropes. Therefore, in such a case, the direction of the pulling force exerted by the traction ropes on the tarpaulin may deviate significantly from the direction of elongation of the clip grooves at the location of the first shuttle device, thereby making the installation of the tarpaulin difficult and time-consuming, and may even cause damage to the tarpaulin, the traction ropes and / or the first elongated rail structure.

[0018] Further advantages are achieved by implementing one or several of the features of the dependent claims. For example, the clip-on roof system may further include: a second elongated rail structure having a first clip-on groove, wherein the second elongated rail structure is configured to be positioned adjacent to the first elongated rail structure for defining a roof bay area, and wherein the second clip-on chord is configured to be inserted into and slidably move within the first clip-on groove of the second elongated rail structure; a second shuttle device, which is fastened to the first tarpaulin, wherein the second shuttle device has a rope attachment structure; a traction rope, which is configured to be attached to the rope attachment structure of the second shuttle device; wherein the second The elongated track structure includes a rope guiding structure configured to hold and guide a traction rope along the second elongated track structure at a position outside the first clip groove; wherein the traction rope and a portion of the second shuttle device are configured to pass through the rope guiding structure of the second elongated track structure when the first tarpaulin is being installed on the first elongated track structure and the second elongated track structure; and wherein the clip-type roof system is configured to simultaneously pull the traction rope of the first shuttle device and the traction rope of the second shuttle device to slide the first tarpaulin on the first elongated track structure and the second elongated track structure.

[0019] In some example embodiments that may be combined with any one or more of the above embodiments, the first elongated track structure is composed of a plurality of elongated track segments connected end to end to form the first elongated track structure together. This enables modular and flexible design of the elongated track structure.

[0020] Similarly, when the clip-on roof system further includes a second elongated rail structure, the second elongated rail structure is composed of a plurality of elongated rail sections connected end to end to collectively form the second elongated rail structure.

[0021] In some example embodiments that can be combined with any one or more of the above embodiments, at least one elongated rail section of the first elongated rail structure comprises a rail holder, in particular two, three or four rail holders, for detachably fastening the elongated rail section to the first roof supporting beam, in particular to the vertical upper side or the vertical lower side of the first roof supporting beam. Thereby, the need for expensive special roof supporting beams with the required clip grooves is eliminated, and when building a clip-type roof system, the user can rely on conventional roof supporting beams without clip grooves, such as lattice girders.

[0022] Similarly, when the clip-on roof system also includes a second elongated rail structure, at least one elongated rail segment of the second elongated rail structure includes a rail retainer, in particular two, three or four rail retainers, which are used to fasten the elongated rail segment to the second roof supporting beam in a detachable manner, in particular to the vertical upper side or the vertical lower side of the second roof supporting beam.

[0023] In some example embodiments that can be combined with any one or more of the above embodiments, the rail holder has a foot for detachably fastening the elongated rail section to the first roof support beam and / or the second roof support beam, and wherein the contact surface of the foot is positioned at a distance of at least 10 cm, particularly at least 25 cm, and more particularly in the range of 10 cm to 150 cm from the first clip groove. Thereby, the risk of the tarpaulin coming into contact with the laterally extending brazing elements of the roof support structure is reduced, and damage and wear associated with such contact are eliminated.

[0024] In some example embodiments that may be combined with any one or more of the above embodiments, the foot of the track holder comprises: a clamping mechanism for attaching the foot to the first roof support beam and / or the second roof support beam in a clamping manner; or at least two spring-loaded pins for removably engaging with corresponding holes in the first roof support beam and / or the second roof support beam. The clamping mechanism provides a universal solution compatible with a large number of different roof support beams, and the clamping mechanism with spring-loaded pins has the following advantages: provides very precise and reliable angular positioning of the elongated track, making the tarpaulin easier to install and remove.

[0025] In some example embodiments, which may be combined with any one or more of the above embodiments, the first elongated track structure is integrally formed in the first roof support beam. This provides for a more compact design.

[0026] Similarly, when the clip-type roof system further includes a second elongated rail structure, the second elongated rail structure is integrally formed in the second roof supporting beam.

[0027] In some example embodiments that can be combined with any one or more of the above embodiments, the rope guide structure of the first elongated track structure and / or the second elongated track structure comprises at least one separate rope guide member positioned on the elongated track segment, in particular two, three, four or five separate rope guide members positioned on the elongated track segment spaced apart longitudinally. Thereby, material, weight and cost can be reduced, because separate rope guide members can be positioned only where needed.

[0028] In some example embodiments, which may be combined with any one or more of the above embodiments, the first elongated track structure and / or the second elongated track structure is composed of at least one curved elongated track section and at least one straight elongated track section, wherein at least one separate rope guide member is positioned on at least one curved elongated track section, and wherein at least one, in particular all, straight elongated track sections are free of the rope guide structure. Thereby, material, weight and cost may be reduced, since separate rope guide members may be positioned only where needed.

[0029] In some example embodiments that may be combined with any one or more of the above embodiments, the first elongated rail structure has an extension at each point along its length in the elongated direction, in a lateral direction located in the plane of the intended roof and perpendicular to the elongated direction, and in a height direction perpendicular to both the elongated direction and the lateral direction, wherein the first elongated rail structure has a first clip groove and a second clip groove, the first clip groove and the second clip groove are positioned on a first lateral side of the first elongated rail structure and are offset from each other in the height direction, and wherein the first elongated rail structure also has a third clip groove and a fourth clip groove, the third clip groove and the fourth clip groove are positioned on a second lateral side of the first elongated rail structure opposite to the first lateral side and are offset from each other in the height direction, so that two separate tarpaulins can be installed in an overlapping arrangement on each lateral side of the first elongated rail structure. Therefore, the clip-type roof system can be designed based on various different combinations of tarpaulins, thereby providing increased flexibility in the size of the clip-type roof and in the size of the tarpaulins used.

[0030] Similarly, when the clip-on roof system also includes a second elongated rail structure, the second elongated rail structure has a first clip-on groove and a second clip-on groove, which are positioned on a first lateral side of the first elongated rail structure and are offset from each other in the height direction, and wherein the second elongated rail structure also has a third clip-on groove and a fourth clip-on groove, which are positioned on a second lateral side of the second elongated rail structure opposite to the first lateral side and are offset from each other in the height direction, so that two separate tarpaulins can be installed in an overlapping arrangement on each lateral side of the second elongated rail structure.

[0031] In some example embodiments that may be combined with any one or more of the above embodiments, the rope guide structure of the first elongated track structure includes: a first rope guide portion, the first rope guide portion is positioned adjacent to the first clip groove and is configured to guide a traction rope connected to a first tarpaulin installed in the first clip groove; a second rope guide portion, the second rope guide portion is positioned adjacent to the second clip groove and is configured to guide a traction rope connected to a second tarpaulin installed in the second clip groove; a third rope guide portion, the third rope guide portion is positioned adjacent to the third clip groove and is configured to guide a traction rope connected to a third tarpaulin installed in the third clip groove; and a fourth rope guide portion, the fourth rope guide portion is positioned adjacent to the fourth clip groove and is configured to guide a traction rope connected to a fourth tarpaulin installed in the fourth clip groove. Having a separate rope guide portion for each clip groove reduces the risk of interference between different traction ropes.

[0032] Similarly, when the clip-strip roof system also includes a second elongated track structure, the rope guiding structure of the second elongated track structure includes: a first rope guiding portion, which is positioned adjacent to the first clip-strip groove and is configured to guide the traction rope connected to the first tarpaulin installed in the first clip-strip groove; a second rope guiding portion, which is positioned adjacent to the second clip-strip groove and is configured to guide the traction rope connected to the second tarpaulin installed in the second clip-strip groove; a third rope guiding portion, which is positioned adjacent to the third clip-strip groove and is configured to guide the traction rope connected to the fifth tarpaulin installed in the third clip-strip groove; and a fourth rope guiding portion, which is positioned adjacent to the fourth clip-strip groove and is configured to guide the traction rope connected to the sixth tarpaulin installed in the fourth clip-strip groove.

[0033] In some example embodiments that may be combined with any one or more of the above embodiments, the first elongated track structure includes: a plurality of separate cord guide members spaced apart and positioned on the outer side of the first elongated track structure; and a plurality of separate cord guide members spaced apart and positioned on the inner side of the first elongated track structure. Positioning the cord guide members on both the inner side and the outer side of the roof support beam provides improved flexibility in the design and implementation of the clip-on roof system. For example, mounting a tarp on both the inner side and the outer side of the roof support beam enables improved insulation.

[0034] Similarly, when the clip-on roof system also includes a second elongated track structure, the second elongated track structure includes: a plurality of separate cord guide members spaced apart and positioned on the outer side of the second elongated track structure; and a plurality of separate cord guide members spaced apart and positioned on the inner side of the second elongated track structure.

[0035] In some example embodiments that may be combined with any one or more of the above embodiments, the rope guide structure of the first elongated track structure and / or the second elongated track structure comprises a separate rope guide channel for each clamping groove of the first elongated track structure and / or the second elongated track structure, thereby reducing the risk of interference between different traction ropes.

[0036] In some example embodiments that can be combined with any one or more of the above embodiments, the rope guide structure of the first elongated track structure and / or the second elongated track structure includes a separate rope guide channel for each clip groove of the first elongated track structure and / or the second elongated track structure, and at least one rope guide channel is sized to be able to hold and guide two traction ropes at the same time. Therefore, two tarpaulins can be installed in the same clip groove, thereby further increasing the flexibility and design options of the clip-type roof system.

[0037] In some example embodiments that may be combined with any one or more of the above embodiments, the first shuttle device and / or the second shuttle device comprises a first part and a second part, wherein the first part is fastened to the first tarpaulin and the second part comprising the rope attachment structure can be fastened to the first part in a detachable manner. This provides improved flexibility for maintenance and repair of the second part, for example, and avoids the need to replace the entire tarpaulin.

[0038] In some example embodiments that may be combined with any one or more of the above embodiments, the first shuttle device and / or the first part of the second shuttle device comprises two plate-like members fastened to each other, and the two plate-like members jointly clamp the first tarpaulin between the two plate-like members. This provides a strong and reliable permanent connection between the plate-like members and the tarpaulin, thereby eliminating the need to remove the shuttle device after installation, as the shuttle device cannot fall off.

[0039] In some example embodiments, which may be combined with any one or more of the above embodiments, at least one of the plate-like elements, in particular both plate-like elements, has a textured inner contact surface, in particular a wavy inner contact surface, facing the first tarpaulin. The textured, in particular wavy inner contact surface provides an improved clamping effect of the plate-like elements.

[0040] In some example embodiments that may be combined with any one or more of the above embodiments, the two plate-like elements of the first part of the first shuttle device and / or the second shuttle device are fastened to each other via rivets or threaded members extending through the first tarpaulin, thereby providing a reliable permanent connection between the plate-like elements and the tarpaulin.

[0041] In some example embodiments, which may be combined with any one or more of the above embodiments, the rope attachment structure of the first shuttle device comprises a protrusion configured to engage in a hole of an end piece of the traction rope. This provides a simple and secure connection of the traction rope to the shuttle device.

[0042] Similarly, when the clip-on roof system further comprises a second elongated track structure, the rope attachment structure of the second shuttle device comprises a protrusion configured to engage in a hole of an end member of the traction rope.

[0043] In some example embodiments, which may be combined with any one or more of the above embodiments, the second part of the first shuttle device and / or the second shuttle device is made of a flat material, in particular a metal sheet such as an aluminum sheet or a steel sheet. This enables the use of a smaller entry opening to the rope guide channel of the rope guide structure, so that the risk of the traction rope being stuck or blocked in the entry opening is reduced.

[0044] In some example embodiments, which may be combined with any one or more of the above embodiments, the second part of the first shuttle device is attached to the first part of the first shuttle device by means of a threaded member.

[0045] Similarly, when the clip-type roof system further comprises a second elongated rail structure, the second part of the second shuttle device is attached to the first part of the second shuttle device by means of a threaded member.

[0046] In some example embodiments, which may be combined with any one or more of the above embodiments, the second portion of the first shuttle device can be selectively attached to either of the two plate-like members of the first portion of the first shuttle device. Thus, the roofer does not have to reposition the tarpaulin in the ground prior to installation, as the roofer can simply attach the shuttle device where needed.

[0047] Similarly, when the clip-type roof system further includes a second elongated rail structure, the second portion of the second shuttle device can be selectively attached to any one of the two plate-like members of the first portion of the second shuttle device.

[0048] In some example embodiments that can be combined with any one or more of the above embodiments, at least one rope guide member of the first elongated track structure has the shape of a closed holder to define a rope guide channel through the at least one rope guide member, wherein the closed holder has an access opening along its periphery for allowing a portion of the first shuttle device, in particular a portion of the second portion of the shuttle device, to extend into the rope guide channel and pass through the rope guide structure. Thereby, the risk of the traction rope being stuck or blocked in the rope guide structure is reduced.

[0049] Similarly, when the clip-type roof system also includes a second elongated track structure, at least one rope guide member of the second elongated track structure has the shape of a closed retainer to define a rope guide channel passing through the at least one rope guide member, wherein the closed retainer has an access opening along its periphery, which is used to enable a portion of the second shuttle device, in particular a portion of the second part of the second shuttle device, to extend into the rope guide channel and pass through the rope guide structure.

[0050] In some example embodiments that can be combined with any one or more of the above embodiments, the entry opening of the closure retainer is sized to be small enough to prevent the traction rope from escaping from the rope guide channel via the entry opening, thereby reducing the risk of the traction rope being stuck or blocked in the entry opening.

[0051] In some example embodiments, which may be combined with any one or more of the above embodiments, the first shuttle device is fastened in a corner region of the first tarpaulin. This enables the transfer of tension from the traction rope to the clip chord.

[0052] Similarly, when the card strip roof system further includes a second elongated track structure, the second shuttle device is fastened in the corner area of ​​the first tarpaulin. Specifically, each of the first shuttle device and the second shuttle device is fastened in a separate corner area of ​​the first tarpaulin.

[0053] In some example embodiments that may be combined with any one or more of the above embodiments, the method may further include: providing a second elongated track structure having a first clip groove and a rope guide structure, and providing a second shuttle device fastened to the first tarpaulin for the first tarpaulin; arranging the first elongated track structure and the second elongated track structure to be spaced side by side, and connecting the first elongated track structure and the second elongated track structure to each other using brazing elements and / or cross bars to define a rigid roof bay; installing a traction rope in the traction rope guide structure of the second elongated track structure, and attaching the traction rope to the traction rope attachment structure of the second shuttle device; wherein the step of assembling the first tarpaulin includes installing the first tarpaulin on the first elongated track and the second elongated track in the following manner On the road: pull the traction rope of the first shuttle device and the traction rope of the second shuttle device at the same time, so as to slide the first clamping strip chord rod in the first clamping strip groove of the first elongated track structure and slide the second clamping strip chord rod in the first clamping strip groove of the second elongated track structure, and at the same time, hold and guide the traction rope of the first shuttle device at the external position outside the first clamping strip groove along the first elongated track structure with the help of the rope guiding structure, and hold and guide the traction rope of the second shuttle device at the position outside the first clamping strip groove along the second elongated track structure with the help of the rope guiding structure, and at the same time, make a part of the first shuttle device pass through the rope guiding structure of the first elongated track structure and make a part of the second shuttle device pass through the rope guiding structure of the second elongated track structure.

[0089] Various aspects of the disclosure will be described below in conjunction with the accompanying drawings that are used to illustrate rather than limit the disclosure, in which like reference numerals represent like elements, and variations of the described aspects are not limited to the specific illustrated embodiments, but are applicable to other variations of the disclosure.

[0090] Figure 1A and Figure 2 The perspective view of the card strip type roof system according to the present disclosure is schematically shown, wherein: Figure 1A shows the assembled roof support structure 1 before a set of tarpaulins are installed, and Figure 2The assembled roof support structure 1 is shown after the set of tarpaulins is installed. The assembled and installed card-strip roof system can be considered to have extensions in the roof width direction 25, in the roof length direction 26 perpendicular to the roof width direction 25, and in the roof height direction 27 perpendicular to both the roof width direction 25 and the roof length direction 26.

[0091] exist Figure 1A , Figure 2 In an example implementation, Figure 1A The assembled roof supporting structure 1 includes four roof supporting beams 2 to 5, namely a first roof supporting beam 2, a second roof supporting beam 3, a third roof supporting beam 4 and a fourth roof supporting beam 5, which are spaced side by side along the roof length direction 26, wherein adjacent roof supporting beams 2 to 5 are structurally connected to each other via brazing elements and / or cross bars 6 to define a rigid frame forming the roof supporting structure 1. Figure 1B An enlarged view of a section of the roof supporting structure 1 in the region of the fourth roof supporting beam 5 is shown.

[0092] One of the main purposes of the roof support structure 1 is to carry and hold the tarpaulin in a desired position and to be able to withstand loads transferred from the tarpaulin to the roof support structure 1 and caused by, for example, wind, snow loads and the like.

[0093] Figure 2 The completed card strip type roof system includes the roof ridge area 13 and the first eave area 18 and the second eave area 19. The portion of the roof located between the roof ridge area 13 and the first eave area 18 or the second eave area 19 can be referred to as the middle area 20.

[0094] Adjacent roof support beams 2 to 5, for example, the first roof support beam 2 and the second roof support beam 3, together define a roof bay 10. Therefore, Figure 2 The roof structure comprises three roof bay areas 10 , 11 , 12 .

[0095] exist Figure 2 In the exemplary embodiment, the first tarpaulin 15 is installed to cover the first roof bay area 10 by the first roof builder 23 and the second roof builder 24, and the first roof builder 23 and the second roof builder 24 cooperate to use two traction ropes 14 to jointly pull the first tarpaulin 15 and install the first tarpaulin 15 on the roof support structure. The second tarpaulin 16 has been installed to cover the second roof bay area 11, and the third tarpaulin 17 has been installed to cover the third roof bay area 12.

[0096] exist Figure 2In the example embodiment of the present invention, the roof is a gambrel roof, but the card strip roof system is also applicable to other types of roof designs, such as flat roofs, pitched roofs, gable roofs, etc.

[0097] The roof has a modular structure, since the roof support structure 1 is composed of a plurality of parts that are temporarily connected. For example, each of the roof support beams 2 to 5 can be composed of a set of straight beam segments and a set of curved beam segments that are connected to each other using, for example, a clamping connection or a form-fitting locking. Similarly, the brazing elements and / or crossbars 6 are also separate parts that are temporarily connected to the roof support beams.

[0098] Therefore, depending on the construction of the modular frame, the roof free span width 7 and the roof height 8 of the final roof may vary greatly. For example, the roof free span width 7 may be in the range of 5 meters to 50 meters or more, and the roof height measured from the vertical support surface at the first eave or the second eave to the roof ridge may be in the range of 0 meters to 30 meters or more.

[0099] Figure 3A Schematically shows Figure 1A A side view of, for example, a first roof support beam 2, wherein Figure 3B shows an enlarged side view of the curved portion of the first roof support beam 2, and Figure 3C An enlarged side view of the straight portion of the first roof supporting beam 2 is shown. Figure 3A The roof support beams 2 stand upright on the support surface 47.

[0100] Figure 4 A perspective view of, for example, a first roof supporting beam 2 is shown in its curved section.

[0101] The roof support beams 2-5 can have a variety of structures, compositions and designs. A particularly attractive design for the roof support beams 2-5 is in the form of a lattice beam, lattice girder or truss beam, due to their high structural strength combined with low weight. Such lattice beams or truss beams can be made using steel, aluminum or other types of metal. The lattice beam or truss beam, sometimes also referred to as a hollow beam, typically includes a top chord 59, a bottom chord 60 and a plurality of relatively straight structural elements 61 that interconnect the top and bottom chords and form a substantially triangular system.

[0102] In particular, by providing the roof support beam 2 in the form of a lattice beam having a top chord 59 and a bottom chord 60 made of a steel tube having an outer diameter of 48.3 mm, the lattice beam is suitable for use as a scaffolding part, i.e. for building a facade scaffolding etc., according to the European standard EN 12810-1 for scaffolding products. The center-to-center distance of the top chord 59 and the bottom chord 60 of the lattice beam may be, for example, 500 mm to further improve compatibility with other parts of the scaffolding system.

[0103] However, the roof support beams are not limited to these types of support beams and may alternatively be of a more robust design and made of fiber reinforced polymer materials and / or concrete materials or the like.

[0104] Reference FIG. 3A to FIG. 3C as well as Figure 4 According to some example embodiments, the first roof support beam 2 carries a removable first elongated rail structure 30, and the first elongated rail structure 30 has a first clip groove 31. This design further increases the modular design of the clip-type roof system, because the roof support beam 2 can be any type of roof support beam, and not necessarily a dedicated clip-type roof support beam with an integrated clip groove. Therefore, scaffolding and / or clip-type roof suppliers can use already available roof support beams as load-bearing members, or nearly any type of roof support beam, thereby reducing costs and complexity to expand the scope of services including the clip-type roof system.

[0105] In addition, in the event that, for example, the first clip groove of the first elongated rail structure 30 is damaged, it is not necessary to replace the entire roof supporting beam, but it is sufficient to replace the first elongated rail structure 30 .

[0106] Since the detachable first elongated track structure 30 is carried by the rigid and load-bearing first roof support beam 2, the first elongated track structure 30 can be designed without any substantial requirements in terms of load capacity. In other words, the first elongated track structure 30 can be designed with relatively low rigidity to save weight and cost.

[0107] The first clip groove 31 may be integrally formed in the first elongated rail structure 30 , for example, by manufacturing the first elongated rail structure 30 as a cost-effective aluminum profile in an aluminum extrusion process or as a cost-effective polymer material profile in a polymer material extrusion process.

[0108] The first elongated rail structure 30 may be manufactured in one piece or may be constructed from multiple parts and / or multiple materials.

[0109] The first clamping groove 31 obviously extends parallel to the elongation direction of the first track structure 30 .

[0110] According to some example embodiments, the first elongated rail structure 30 comprises a plurality of rail retainers 35 for removably fastening the first elongated rail structure 30 to the first roof support beam 2. The rail retainers 35 may, for example, be fastened to the first elongated rail structure 30 or may be integrally formed within the first elongated rail structure 30 and may be configured to enable quick and secure temporary attachment of the first elongated rail structure 30 to the first roof support beam 2 by the roof builders 23, 24. The quick and secure temporary attachment may, for example, be achieved by means of rail retainer feet 9 comprising clamping members or using a form-fitting locking device such as a pin and hole attachment.

[0111] However, the clip-type roof system according to the present disclosure is not limited to a separate or detachable first elongated rail structure 30. In other words, in some example embodiments (not shown), the first elongated rail structure 30 may be incorporated into the first roof supporting beam 2 or permanently attached to the first roof supporting beam 2. For example, the first roof supporting beam 2 may include an integrally formed first clip groove 31, or the first elongated rail structure 30 having the first clip groove 31 may be permanently attached to the first roof supporting beam 2, for example, by welding or the like.

[0112] Fig.13A A top view of a tarpaulin, such as the first tarpaulin 15, is schematically shown, and Fig. 13B The same view is schematically shown, but here also includes a first shuttle 40 , a second shuttle 41 , a third shuttle 42 and a fourth shuttle 43 , each of which is installed in a separate corner portion of the first tarpaulin 15 . Fig. 13B Also shown are four traction ropes 14 , each connected to each of the first to fourth shuttle devices 40 , 43 .

[0113] Reference Figure 2 , Fig.13A and Fig. 13B The first tarpaulin 15 can be in the form of a rectangle having opposite first and second side edges 28 and 29 and opposite third and fourth side edges 36 and 37, wherein the first tarpaulin has a first clip chord 38 positioned along the first side edge 28 and a second clip chord 39 positioned along the second side edge 29.

[0114] Therefore, the first side edge 28 and the third side edge 36 are connected at the first corner area 48 of the first tarpaulin 15, the second side edge 29 and the third side edge 36 are connected at the second corner area 49 of the first tarpaulin 15, the first side edge 28 and the fourth side edge 37 are connected at the third corner area 50 of the first tarpaulin 15, and the second side edge 29 and the fourth side edge 37 are connected at the fourth corner area 51 of the first tarpaulin 15.

[0115] In other words, the rectangular periphery of the first tarpaulin 15 is thus defined in sequence by the first side edge 28 , the third side edge 36 , the second side edge 29 and the fourth side edge 37 .

[0116] The traction rope 14 can be made of various materials, such as jute rope or polypropylene rope or other types of plastic ropes. The traction rope 14 can have a diameter of about 10mm to 30mm to be able to be well gripped by the roof builder. Alternatively, a wire rope, such as a wire rope used with a certain type of wire rope winding machine, can be used to achieve electric traction of the traction rope 14.

[0117] Figure 5 A stereoscopic view of a first tarpaulin 15 and a second tarpaulin 16 in an assembled state together with a first elongated rail structure 30 is schematically shown, wherein a first shuttle device 40 is attached to the first tarpaulin 15 and connected to a traction rope 14, and wherein a second shuttle device 41 is attached to an adjacent second tarpaulin 16 and connected to a traction rope 14. Figure 5 Also shown is a rail holder 35 with an associated rail holder foot 9 , which is designed for detachable fastening on the first roof support beam 2 .

[0118] Figure 6 A cross-sectional view of the first tarpaulin 15 in an assembled state with the first elongated track structure 30 is shown. Specifically, the first clip chord 38 of the first tarpaulin 15 is installed in the first clip groove 31 of the first elongated track structure 30. Figure 6 Also shown is a first shuttle device 40 connected to the first tarpaulin 15 and attached to the traction rope 14 .

[0119] Reference Figure 5 and Figure 6 When the first tarpaulin 15 is installed on the first elongated track structure 30, the first clip chord 38 of the first tarpaulin should be more or less completely slidably inserted into the first clip groove 31 of the first elongated track structure 30 to provide a firm and sealed connection between the first side edge 28 of the first tarpaulin and the first elongated track structure 30.

[0120] The installation of the first tarpaulin 15 on the first elongated rail structure 30 is performed, for example, by the roof builder inserting the end of the first clip chord 38 of the first tarpaulin 15 into the end of the first clip groove 31 of the first elongated rail structure 30. This can be performed manually, for example. Thereafter, a traction force is applied to the first tarpaulin 15 for sliding the first clip chord 38 into the first clip groove 31 until the desired position is reached. The traction force is applied to the first tarpaulin 15, for example, via the traction rope 14 of the first shuttle device 40.

[0121] FIG. 10 schematically shows a Fig. 20A FIG. 2 is a cross-sectional view of an exemplary embodiment of a first elongated rail structure 30 at the cross-sectional cutting line AA in FIG. Figure 6 , but additionally a second tarpaulin 16 and a rope guide structure 52 are shown.

[0122] Specifically, the first clip chord 38 of the first tarpaulin 15 is installed in the first clip groove 31 of the first elongated track structure 30, and the first clip chord 38 of the second tarpaulin 16 is installed in the second clip groove 32 of the first elongated track structure 30. In addition, the first shuttle device 40 is attached to the first tarpaulin 15, and the traction rope 14 attached to the first tarpaulin 15 via the first shuttle device 40 is guided along the first elongated track structure 30 by means of the inner portion 21 of the rope guide structure 52. In addition, the first shuttle device 40 is attached to the second tarpaulin 16, and the traction rope 14 attached to the second tarpaulin 16 via the first shuttle device 40 is guided along the first elongated track structure 30 by means of the outer portion 22 of the rope guide structure 52.

[0123] FIG. 12A to FIG. 12C Three different installation stages of an example embodiment of the first elongated track structure 30 with the rope guide structure 52 and the first tarpaulin 15 installed in the first clip groove 31 of the first elongated track structure 30 are shown.

[0124] In the example embodiment of the card-strip roof system having a first elongated rail structure 30 with four card-strip grooves, the card-strip roof system according to the present disclosure provides greater flexibility in roof size because one, two or three separate tarpaulins can be combined to cover a single roof bay area. For example, Fig.14A , Fig.15A and Fig.16A Three different roof designs are shown that can be built using the same type of track structure.

[0125] Fig.14A A slat roof system with a single tarpaulin mounting is schematically shown, and Fig. 14BAn example of a cross-sectional view through a first elongated rail structure 30 of said single tarpaulin mounting is shown. A single tarpaulin mounting in this context refers to a mounting in which a single tarpaulin 15 extends over the entire length of the roof bay area, i.e. in the roof width direction, and in which the size of the roof in the roof length direction 26 is determined by the number of tarpaulins mounted side by side. Thus, in this type of mounting, the size of the roof in the roof width direction 25 is limited to the length of the single tarpaulin 15. Obviously, however, a single tarpaulin mounting may comprise a double layer of tarpaulins, i.e. a first tarpaulin 15 mounted in a first clip groove 31 and a second tarpaulin 16 mounted in a second clip groove 32, such that the two tarpaulins overlap.

[0126] In more detail, Fig. 14B A single-layer mounting piece is shown, which has a first tarpaulin 15 installed in a first clip groove 31 of a first elongated rail structure 30 and a second tarpaulin 16 installed in a third clip groove 33 of the first elongated rail structure 30, wherein the traction rope of the first tarpaulin 15 is guided by a first rope guide portion 53 located near the first clip groove 31, and wherein the traction rope of the second tarpaulin 16 is guided by a third rope guide portion 55 located near the third clip groove 33.

[0127] FIG. 8A to FIG. 8D The basic steps for installing a single tarpaulin mounting are schematically illustrated in FIG. Fig. 8A , before starting to install the first tarpaulin 15, the roof support structure 1 and its roof support beams 2 to 5 and the brazing elements 6 are installed. This can be performed, for example, by first building the roof bay at a convenient location, such as on the ground close to the desired final location, and then lifting the completed roof bay to the desired final location using a crane or the like, and finally connecting the roof bays using brazing elements. A roof bay refers to two roof support beams connected to each other by brazing elements to form a rigid entity. Alternatively, a single roof support beam can be assembled and then lifted to the desired final location and then connected to an adjacent roof support beam using brazing elements 6.

[0128] With regard to the construction of the roof segment on the ground and before the lifting takes place, all necessary traction ropes are installed in the rope guide structure 52 , since the pre-installed traction ropes 14 make it possible to avoid unnecessary climbing on the assembled roof support structure 1 .

[0129] When the tarpaulin has not yet been installed, the assembly, lifting and installation of the roof support structure 1 and its roof support beams 2 to 5 and the brazing elements 6 are simplified because the wind sensitivity is reduced and it is simpler to climb up the roof support structure to connect adjacent roof support beams before installing the tarpaulin 15, 16.

[0130] Reference Figure 8B When the roof support structure 1 and its roof support beams 2 to 5 and the brazing elements 6 are completed, the installation of the first tarpaulin 15 can begin. This can be performed in the following way: firstly, the first tarpaulin 15 is placed at a position close to, for example, the first eaves area 18, and the ends of the first clip chord rods 38 and the second clip chord rods 39 of the first tarpaulin 15 are inserted into the appropriate clip grooves 31 to 34 of the first elongated rail structure 30 and the second elongated rail structure 62, and the pre-installed traction rope 14 is connected to the first shuttle device 40 and the second shuttle device 41. It should be noted that the second shuttle device 41 is in Figure 8B It is not visible in the figure because it is located on the back of the first tarpaulin 15.

[0131] Afterwards, refer to Figure 8C and Fig.8D The roof builders 23 and 24 located at the second eaves area 19 can manually pull the traction rope 14 connected to the first shuttle device 40 and the second shuttle device 41 to install the first tarpaulin 15 until the first tarpaulin 15 covers the entire first roof bay area 10. Fig.8D As shown in .

[0132] Fig.15A A slatted roof system with dual tarpaulin mountings is schematically shown, and Fig. 15B An example of a cross-sectional view through the first elongated rail structure 30 of the double tarpaulin mounting is shown. A double tarpaulin mounting herein refers to a mounting in which the two tarpaulins partially overlap each other so that no tarpaulin extends over the entire length of the roof bay area, i.e., in the roof width direction. In other words, the first tarpaulin 15 covers a first portion of the roof bay area and the second tarpaulin 16 covers a second portion of the roof bay area, wherein the first and second tarpaulins. Therefore, in this type of mounting, the size of the roof in the roof width direction 25 is not limited to the length of a single tarpaulin 15, but rather the combined length of the first tarpaulin 15 and the second tarpaulin 16 after deducting the overlapping portion of one of the first tarpaulin 15 and the second tarpaulin 16.

[0133] In more detail, Fig. 15B Shown are a first tarpaulin 15 installed in a first clip groove 31 of a first elongated rail structure 30, a second tarpaulin 16 installed in a second clip groove 32 of the first elongated rail structure 30, a third tarpaulin 17 installed in a third clip groove 33 of the first elongated rail structure 30, and a fourth tarpaulin 57 installed in a fourth clip groove 34 of the first elongated rail structure 30.

[0134] Therefore, the first elongated rail structure 30 has an extension at each point along its length in the elongation direction 76, in the lateral direction 77 located in the plane of the intended roof and perpendicular to the elongation direction, and in the height direction 78 perpendicular to both the elongation direction 76 and the lateral direction 77, wherein the first elongated rail structure 30 has a first clip groove 31 and a second clip groove 32, the first clip groove 31 and the second clip groove 32 are located on a first lateral side of the first elongated rail structure 30 and are offset from each other in the height direction 78, and wherein the first elongated rail structure 30 also has a third clip groove 33 and a fourth clip groove 34, the third clip groove 33 and the fourth clip groove 34 are located on a second lateral side of the first elongated rail structure 30 opposite to the first lateral side and are offset from each other in the height direction 78, so that two separate tarpaulins 15, 16 can be installed on each lateral side of the first elongated rail structure 30 in an arrangement that overlaps each other.

[0135] In addition, the traction rope 14 of the first tarpaulin 15 is guided by the first rope guide portion 53 located near the first clamping strip groove 31, the traction rope 14 of the second tarpaulin 16 is guided by the second rope guide portion 54 located near the second clamping strip groove 32, the traction rope 14 of the third tarpaulin 17 is guided by the third rope guide portion 55 located near the third clamping strip groove 33, and the traction rope 14 of the fourth tarpaulin 57 is guided by the fourth rope guide portion 56 located near the fourth clamping strip groove 34.

[0136] 9A to 9C The basic steps for installing a double tarp mounting are schematically illustrated in FIG. Fig.9A First, the roof support structure 1 and its roof support beams 2 to 5 and the brazing element 6 are installed, and the required traction ropes 14 are pre-installed in the rope guide structure 52, the first tarpaulin 15 and the second tarpaulin 16 are positioned near, for example, the first eaves area 18 and the second eaves area 19, respectively, and the pre-installed traction ropes 14 are connected to the first shuttle device 40 and the second shuttle device 41 of the first tarpaulin 15 and the second tarpaulin 16. This basically corresponds to the above reference Fig. 8A The activities described.

[0137] Afterwards, refer to Fig. 9B , the ends of the first clip chord 38 and the second clip chord 39 of the first tarpaulin 15 are inserted into the appropriate clip grooves 31-34 of the first elongated track structure 30 and the second elongated track structure 62, and the roof builders 23, 24 located at the second eaves area 19 can manually pull the traction rope 14 connected to the first shuttle device 40 and the second shuttle device 41 to install the first tarpaulin 15 until the first tarpaulin 15 covers a portion of the first roof bay area 10.

[0138] Afterwards, refer to Fig. 9C , insert the ends of the first clip chord 38 and the second clip chord 39 of the second tarpaulin 16 into the appropriate clip grooves 31-34 of the first elongated track structure 30 and the second elongated track structure 62, and the roof builders 23, 24 located at the first eaves area 18 can manually pull the traction rope 14 connected to the first shuttle device 40 and the second shuttle device 41 to install the second tarpaulin 15 until the second tarpaulin partially overlaps the first tarpaulin 15 and thus covers the rest of the first roof bay area 10. Fig. 9C , the third side edge 36 of the second tarpaulin 16 is positioned to overlap with the first tarpaulin 15. This corresponds to the final position of the first tarpaulin 15 and the second tarpaulin 16.

[0139] Fig.16A A card-slat roof system with three tarpaulin mountings is schematically shown, and Fig. 16B An example of a cross-sectional view through the first elongated rail structure 30 of the three-tarp mounting is shown. A three-tarp mounting herein refers to a mounting in which two separate tarps are positioned to be spaced apart and non-overlapping, and in which another tarp is arranged to partially overlap each of the two spaced apart tarps. In other words, a first tarp 15 covers a first portion of the roof bay area, another tarp 58 is arranged in the same clip groove as the first tarp 15, but is spaced apart and non-overlapping from the first tarp 15, and a second tarp 16 is arranged in another clip groove and partially overlaps both the first tarp 15 and the another tarp 58. In this type of mounting, the size of the roof in the roof width direction 25 corresponds to the total length of each of the first tarp 15 and the another tarp 58 plus the portion of the second tarp 16 that does not overlap with any portion of the first tarp 15 and the another tarp 58.

[0140] In more detail, Fig. 15B Shown are a first tarpaulin 15 installed in a first clip groove 31 of a first elongated rail structure 30, a second tarpaulin 16 installed in a second clip groove 32 of the first elongated rail structure 30, a third tarpaulin 17 installed in a third clip groove 33 of the first elongated rail structure 30, and a fourth tarpaulin 57 installed in a fourth clip groove 34 of the first elongated rail structure 30.

[0141] The traction rope 14 of the first tarpaulin 15 is guided by the first rope guide part 53 located near the first clamping strip groove 31, the traction rope 14 of the second tarpaulin 16 is guided by the second rope guide part 54 located near the second clamping strip groove 32, the traction rope 14 of the third tarpaulin 17 is guided by the third rope guide part 55 located near the third clamping strip groove 33, and the traction rope 14 of the fourth tarpaulin 57 is guided by the fourth rope guide part 56 located near the fourth clamping strip groove 34.

[0142] The other tarpaulin 58 is Fig. 16B However, the traction rope 59 attached to the other tarpaulin 58 is included in the Fig. 16B The traction rope 59 attached to the other tarpaulin 58 is positioned here together with the traction rope of the first tarpaulin 15 in the first rope guide part 53, because such sharing of the first rope guide part 53 enables the first tarpaulin 15 and the other tarpaulin 58 to be installed in the same clip groove 31.

[0143] exist FIG. 11A to FIG. 11D The basic steps for installing a triple tarp mounting are schematically illustrated in FIG. Fig.11A First, the roof supporting structure 1 and its roof supporting beams 2 to 5 and the brazing element 6 are installed, and the required traction ropes 14 are pre-installed in the rope guide structure 52, and the first tarpaulin 15 and the second tarpaulin 16 are positioned near, for example, the first eaves area 18 and the second eaves area 19, respectively, and the pre-installed traction ropes 14 are connected to the first shuttle devices 40 and the second shuttle devices 41 of the first tarpaulin 15 and the second tarpaulin 16.

[0144] Thereafter, the ends of the first clip chord bar 38 and the second clip chord bar 39 of the first tarpaulin 15 are inserted into the appropriate clip grooves 31-34 of the first elongated track structure 30 and the second elongated track structure 62, and the roof builders 23, 24 located at the second eaves area 19 can manually pull the traction rope 14 connected to the first shuttle device 40 and the second shuttle device 41 to install the first tarpaulin 15 until the first tarpaulin 15 covers a portion of the first roof bay area 10. Fig.11A In the embodiment, the fourth side edge 37 of the first tarpaulin 15 has not yet reached the roof ridge at the final position.

[0145] Afterwards, refer to Fig. 11B, insert the ends of the first clip chord rod 38 and the second clip chord rod 39 of the second tarpaulin 16 into the appropriate clip grooves 31-34 of the first elongated track structure 30 and the second elongated track structure 62, especially the clip grooves that are the same as the clip grooves used for the first tarpaulin 15, and the roof builders 23, 24 located at the first eaves area 18 can manually pull the traction rope 14 connected to the first shuttle device 40 and the second shuttle device 41 to install the second tarpaulin 16. Fig. 11B In the embodiment, the third side edge 36 of the second tarpaulin 16 has not yet reached the fourth side edge 37 of the first tarpaulin 15 at the final position, thereby leaving a residual gap between the first tarpaulin 15 and the second tarpaulin 16 .

[0146] Afterwards, refer to Fig. 11C , insert the ends of the first clip chord 38 and the second clip chord 39 of the other tarpaulin 58 into the appropriate clip grooves 31-34 of the first elongated rail structure 30 and the second elongated rail structure 62, in particular not into the clip grooves occupied by the first tarpaulin 15 and the second tarpaulin 16, and the roof builders 23, 24 can manually pull the traction rope 14 connected to the first shuttle device 40 and the second shuttle device 41 to install the other tarpaulin 58 to cover the remaining gap. Fig.11D The clip-on roof system is shown when the further tarpaulin 58 has reached a final position and the entire roof bay area 10 is covered.

[0147] The lengths of the first tarpaulin 15, the second tarpaulin 16 and the further tarpaulin 58 can be selected according to the circumstances and can be, for example, equal or different, thereby providing the roofer with great flexibility in roof construction.

[0148] See for example Figure 3A , Figure 3B , Figure 4 Figure 10 FIG. 12A to FIG. 12C , Fig. 14B , Fig. 15B and Fig. 16B The rope guiding structure 52 can be a separate part attached to the first elongated rail structure 30 or integrally formed in the first elongated rail structure 30, and is configured to hold and guide one or more traction ropes 14, 59 along the first elongated rail structure 30 at a position outside the first clamping strip groove 31 to the fourth clamping strip groove 34 of the first elongated rail structure 30.

[0149] Said another way, the rope guide structure 52 is arranged to prevent the traction ropes 14, 59 from escaping from the rope guide structure 52 and thereby preventing the traction ropes 14, 59 from shifting relative to the first elongated track structure 30, as this would potentially hinder smooth and low friction sliding movement of the clip chords in the associated clip grooves.

[0150] Aligning the traction ropes 14, 59 with the first elongated track structure 30 generally results in a smooth and low friction sliding movement of the clip chords in the associated clip grooves, since such an arrangement does not induce any lateral forces in the clip chords and thereby does not induce additional friction between the clip chords in the associated clip grooves.

[0151] Others say that without the rope guide structure 52 arranged on the first elongated track structure 30, there is a great risk that the pulling angle of the traction ropes 14, 59 at the location of the first shuttle device 40 deviates significantly from the elongation direction of the first elongated track structure 30. This problem may also be exacerbated in embodiments in which the first elongated track is vertically displaced from the frame, because the frame supports are located further away from the track.

[0152] Furthermore, in the absence of the rope guide structure 52 arranged on the first elongated rail structure 30, the traction rope may be more easily stuck in the roof supporting beam or the roof supporting structure 1, and during the lifting and installation of the roof supporting beam, the traction rope may be more easily shifted to an inconvenient position, and the traction ropes may be more easily confused with each other due to the lack of any specific position.

[0153] In addition, when relying on the underlying roof support structure, such as a brazing element, to guide the traction rope, it is usually necessary to install / remove the tarpaulin in a certain order, i.e., first install the outer tarpaulin during installation, and first remove the inner tarpaulin during removal, because if the tarpaulin installed first is installed in the inner bar groove, the tarpaulin may form a barrier between the outer bar groove and the traction rope 14.

[0154] In addition, if Fig. 20A The insufficient support of the traction ropes is even greater when, as schematically shown in , the elongated rail structure is mounted on the underside of the roof support beams, since then the brazing elements 6 of the frame structure 1 cannot be used.

[0155] All these problems are solved by providing a rope guide structure 52 arranged on the first elongated track structure 30, because the position of the traction rope is reliably controlled to avoid any problems with the traction rope during installation / removal and to ensure a smooth and low-friction sliding movement of the clip chord in the associated clip groove.

[0156] Since, for example, the first shuttle device is fastened to the traction rope, the traction rope not only passes through the rope guide structure 52 of the first elongated track structure, but also passes through a part of the first shuttle device. Therefore, the rope guide structure 52 cannot have a completely closed periphery, but can have a relatively small passage for enabling a part of the first shuttle device to pass through the almost closed periphery of the rope guide structure 52.

[0157] Therefore, referring to e.g. Figure 1A To Figure 1C, FIG. 3A to FIG. 3C , Figures 4 to 6 Figure 10 FIG. 12A to FIG. 12C , FIG. 13A to FIG. 13B , FIG. 14A to FIG. 14B , FIG. 15A to FIG. 15B as well as FIG. 16A to FIG. 16B The present disclosure relates to a card-strip roof system, which includes: a first elongated track structure, the first elongated track structure having a first card-strip groove; a first tarpaulin, the first tarpaulin is in a rectangular form with opposite first and second side edges, wherein the first tarpaulin has a first card-strip chord located along the first side edge and a second card-strip chord located along the second side edge, and wherein the first card-strip chord is configured to be inserted into the first card-strip groove of the first elongated track structure and can be slidably moved in the first card-strip groove of the first elongated track structure; a first shuttle device, the first shuttle device A shuttle device is fastened to a first tarpaulin, wherein the first shuttle device has a rope attachment structure 83; a traction rope 14, the traction rope 14 is configured to be attached to the rope attachment structure 83 of the first shuttle device 40; wherein the first elongated track structure includes a rope guide structure, which is configured to hold and guide the traction rope along the first elongated track structure at a position outside the first clamping strip groove; and wherein the traction rope and a portion of the first shuttle device are configured to pass through the rope guide structure of the first elongated track structure when the first tarpaulin is installed on the first elongated track structure.

[0158] In addition, referring to e.g. Figure 1A To Figure 1C, FIG. 3A to FIG. 3C , Figures 4 to 6 Figure 10 FIG. 12A to FIG. 12C , FIG. 13A to FIG. 13B , FIG. 14A to FIG. 14B , FIG. 15A to FIG. 15B and FIG. 16A to FIG. 16B ,as well as FIG. 8A to FIG. 8D , 9A to 9C as well as FIG. 11A to FIG. 11DThe card-strip roof system also includes: a second elongated track structure 62, the second elongated track structure 62 having a first card-strip groove 31, wherein the second elongated track structure is configured to be positioned close to the first elongated track structure to define a roof bay area, and wherein the second card-strip chord is configured to be inserted into the first card-strip groove of the second elongated track structure and can be slidably moved in the first card-strip groove of the second elongated track structure; a second shuttle device, which is fastened to the first tarpaulin, wherein the second shuttle device 41 has a rope attachment structure 83; a traction rope 14, which is configured to be attached to the second shuttle device 41 a rope attachment structure 83; wherein the second elongated track structure includes a rope guiding structure, which is configured to hold and guide the traction rope along the second elongated track structure at a position outside the first clip groove; wherein the traction rope and a portion of the second shuttle device are configured to pass through the rope guiding structure of the second elongated track structure when the first tarpaulin is installed on the first elongated track structure and the second elongated track structure; and wherein the clip-type roof system is configured to simultaneously pull the traction ropes of the first shuttle device and the second shuttle device to slide the first tarpaulin on the first elongated track structure and the second elongated track structure.

[0159] Fig. 20A A side view of an assembled first roof supporting beam 2 is schematically shown, with a first elongated rail structure 30 temporarily fastened on the upper side of the first roof supporting beam 2 and a second elongated rail structure 62 temporarily fastened on the lower side of the first roof supporting beam 2 .

[0160] The first elongated rail structure 30 and the second elongated rail structure 62 can have similar or identical designs, i.e., similar or identical types and numbers of strip grooves 31 to 34 and similar or identical types of rope guide structures 52, so that the same type of tarpaulin can be selectively installed in the first elongated rail structure 30 or the second elongated rail structure 62.

[0161] This dual installation type of the tarpaulin both above and below the first roof support beam 2 can be used to improve thermal insulation, etc. In addition, if desired, a card-slat roof system can be built using only the second elongated rail structure 62, i.e., the lower rail structure 62.

[0162] Fig. 20B Schematically shows Fig. 20A A side view of an exploded view of the first roof support beam 2. Thus, Fig. 20B An example embodiment of a modular construction of the first roof support beam, the first elongated track structure 30, and the second elongated track structure 62 is shown.

[0163] In other words, the first roof supporting beam 2 can be composed of a plurality of supporting beam elements 63, which can have various forms, such as straight elements and curved elements, and thus the desired first roof supporting beam 2 can be constructed by assembling and fastening appropriate groups of supporting beam elements 63 to each other.

[0164] Similarly, the first elongated rail structure 30 is composed of a plurality of elongated rail segments 64 that are continuously connected end to end to form the first elongated rail structure 30. Likewise, the second elongated rail structure 62 is also composed of a plurality of elongated rail segments 64 that are continuously connected end to end to form the second elongated rail structure 62.

[0165] exist Fig. 20B In the exemplary embodiment of FIG. 5 , each of the first elongated rail structure 30 and the second elongated rail structure 62 is composed of a curved elongated rail segment 64 and a plurality of straight elongated rail segments 64 .

[0166] The straight elongated rail sections 64 of the first elongated rail structure 30 and the second elongated rail structure 62 may be identical so that the straight elongated rail sections 64 may be fastened to both the upper and lower sides of the first roof supporting beam 2 .

[0167] The curved elongated rail sections 64 of the first elongated rail structure 30 and the second elongated rail structure 62 are different in that the rail retainers 35 used to attach the curved elongated rail sections 64 to the first roof supporting beam 2 are located on opposite sides.

[0168] At least one elongated rail segment 64 of the first elongated rail structure 30 and / or the second elongated rail structure 62 includes a rail retainer 35, in particular two, three or four rail retainers 35, which are used to fasten the elongated rail segment 64 to the first roof supporting beam 2 in a detachable manner, in particular to the vertical upper side or lower side of the first roof supporting beam 2.

[0169] Reference Fig. 20A The rail holder 35 has a foot 9 for removably fastening the elongated rail section 64 to the first roof support beam 2, and the contact surface 66 of the foot 9, i.e. the surface of the foot that contacts and bears against the first roof support beam, is spaced from the first clip groove 31 by a distance 65 of at least 10 cm, in particular at least 25 cm, and more particularly in the range of 10 cm to 150 cm, in particular 15 cm to 50 cm, the distance 65 being measured in the direction opposite to the elongation direction of the elongated rail section. This reduces the risk of damage and / or wear of the tarpaulin due to interference with the roof support structure 1.

[0170] Fig.17 and 18A to Fig.18C An exemplary embodiment of a foot 9 of a rail holder 35 is schematically shown, wherein: Fig.17 A perspective view of the rail holder 35 with the foot 9 is shown approaching the first roof support beam 2 with the locking hole 67 or recess, Fig.18A shows a side view of the same location, Fig.18B The foot 9 is shown after its contact surface 66 is in contact with the first roof support beam 2, but before the two locking pins 68 of the foot 9 are inserted into the associated locking holes 67 or recesses of the first roof support beam 2, and Fig.18C The foot 9 is shown after its locking pin 68 has been inserted into the associated locking hole 67 or recess of the first roof supporting beam 2 .

[0171] exist Fig.17 as well as 18A to 18C In the exemplary embodiment of FIG. Fig.18C The locking position shown in FIG. 6 is spring loaded, but the locking pin 68 can be selectively set in the open state and the closed state by the rotational movement of the two control arms 69.

[0172] The locking pin 68 may, for example, have a slightly tapered shape at least over a certain length of the locking pin, so that the tapered portion of the locking pin may interact with the locking hole or recess 67 to ensure increased stability and eliminate play.

[0173] The reliable and precise angular positioning of the foot 9 on the first roof support beam 2 provided by the locking pin 68 when the locking pin 68 is engaged in the locking hole 67 is advantageous because it ensures that adjacent rail holders 35 are mounted parallel to each other. Therefore, the distance between the clip grooves of the adjacent first elongated rail structures 30 and the second elongated rail structures 62 is constant and within a relatively tight tolerance over the length of the first elongated rail structures 30 and the second elongated rail structures 62, making it easier to install and remove the tarpaulin in the clip grooves. Other statements are that when adjacent rail holders 35 are not mounted parallel to each other, i.e. slightly tilted relative to each other, the distance between the clip grooves of the adjacent first elongated rail structures 30 and the second elongated rail structures 62 is too small or too large, making the installation / removal of the tarpaulin more difficult.

[0174] Referring to the schematic diagram below FIG. 19A to FIG. 19C Another example embodiment of a foot 9 is described, which shows a foot 9 with two spring-loaded pins 68 arranged to have a snap-fit ​​function. In other words, by default, the locking pins 68 are always pushed forward towards the protruding position by means of the mechanical spring means 70, as shown in FIG. Fig.19A shown.

[0175] When the foot is pushed toward the roof support beam 2 as depicted by the foot movement arrow 73, the locking pin 68 is temporarily and automatically retracted to the retracted position. Specifically, the pushing causes the locking pin 68 to automatically and temporarily retract due to contact with the outer rounded surface of the roof support beam 2, as shown in FIG. Fig.19B as shown in .

[0176] When the support foot 9 moves further toward the roof support beam 2, the contact surface 66 of the support foot 9 contacts the roof support beam 2, and the locking pin 68 can be pushed into the locking hole 67 by the mechanical spring device 70, so that the support foot 9 and the track holder 35 are firmly and reliably connected to the roof support beam 2, as shown in FIG. Fig.19C as shown in .

[0177] The front end 71 of the locking pin 68 may have a slightly tapered shape to ensure increased stability and eliminate play.

[0178] In other words, in some example embodiments, the foot 9 of the track retainer 35 may include at least two spring-loaded pins 68, which are used to engage with corresponding holes 67 located in the first roof support beam 2 in a detachable manner to safely and securely connect the track retainer 35 and the associated first elongated track structure 30 to the first roof support beam 2.

[0179] The rail holder is then removed by, for example, manually pushing the two spring-loaded pins 68 backwards and simultaneously lifting the foot and rail holder off the support beam 2. FIG. 19A to FIG. 19C Snap-fit ​​feet 9.

[0180] According to an alternative exemplary embodiment (not shown), the foot 9 of the rail holder 35 may include at least one clamping mechanism for clamping and attaching the foot 9 to the first roof supporting beam 2. The clamping mechanism may be implemented using, for example, screw members or the like.

[0181] The rail retainer 35 may include an elongated beam having a first end and a second end, wherein the first end of the beam is provided with a rail attachment interface, which is configured to enable a permanent or detachable rigid connection with the first elongated rail structure 30, and wherein the second end 46 of the beam is provided with a support foot 9 for enabling a detachable connection with the first roof supporting beam 2.

Thus, two tarpaulins can be installed in the same clip groove from opposite directions, and the traction ropes 14 attached to the first tarpaulin and the second tarpaulin therefore share the rope guide channel 79.

Thus, in the event of damage or the like, the second portion 82 of the first shuttle device 40 can be replaced separately, and the first portion 81 of the first shuttle device 40 can be reused together with the first tarpaulin 15.

[0189] In more detail, the first portion 81 may be permanently fastened to the first tarpaulin 15 and to the second portion 82 , for example by means of one or more rivets extending through the first tarpaulin 15 or by gluing.

In other words, the rope attachment structure 83 may include a hole 87, and the end piece 86 of the traction rope 14 may include a protrusion 86, such as a pin, which is configured to engage in the hole 87.

Disconnection of the end piece 88 is achieved by turning the end piece 88 90 degrees so that the elongated hole 87 of the end piece 88 is aligned with the elongated top plate 46 of the protrusion 86, as the parts can be disconnected thereby. Before turning the end piece 88, disconnection is not possible due to the obstruction caused by the misalignment between the elongated hole 87 of the end piece 88 and the elongated top plate 46 of the protrusion 86. This arrangement achieves a quick and user-friendly connection / disconnection of the traction rope 14 to the first shuttle device 40, while also providing a relatively reliable connection during normal use of the shuttle device 40 and the traction rope 14.

Therefore, the traction force transmitted from the traction rope 14 to the tarpaulin is mainly applied to the corner regions 48-51, which enables the traction force to be effectively transmitted to the adjacent first and second clip chords 38 and 39.

Thus, the grid guard rail 6 is arranged to be located between the adjacent first roof support beam 2 and the second roof support beam 3, as also shown in FIG. Figure 1A As shown in .

[0205] The attachment interface 93 of each foot 9 may be provided in the form of a bracket 95 provided on each side of the foot 9 for enabling the grid guard rail 6 to be attached to adjacent roof support beams on both sides. In addition, the attachment interface 93 of each foot 9 may be provided with a flat support surface 94 located on each side of the foot 9 for engaging with four hook-shaped attachments 92, thereby further providing improved stability of the completed roof support structure 1. The bracket 95 and flat support surface 94 of the foot 9 are also provided on the side of the foot 9. Figure 2 and Fig.18B Shown in.

[0206] In some example embodiments, the track holder 35 may be made of a separate leg 9 that is detachably connected to a separate elongated beam to form the track holder 35. This design enables the use of the separate leg as a coupling member for connecting a brazing element or scaffolding portion to a roof support beam by means of the attachment interface 93 of the leg 9.
