Description

Technical Field

[0001] The present invention relates to a temporary protective roofing system, in particular a card strip roofing system, and a method for assembling such a roofing system. The temporary protective roofing system is suitable, for example, for temporary facilities, but can alternatively be used for more permanent buildings. The temporary protective roofing system is suitable, for example, as a weather protection device.

[0002] Furthermore, even though the temporary protection roof system according to the present disclosure will be mainly described with respect to a roof, the temporary protection 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] Temporary protective roof systems, such as clip-slat roof systems, are known in the prior art. These known clip-slat roof systems usually have specially designed roof support beams with integrated clip-slat grooves for enabling the installation of a awning cloth extending between two adjacent support beams.

[0004] The card bar roof system includes a sheet of fabric or awning cloth with a card bar chord attached to the side edges of the fabric, and a card bar groove may be provided in the support beam. When the card bar chord is inserted into the card bar groove, a continuous sealed connection between the fabric and the support beam is completed. Card bars are used in a variety of applications including permanent and semi-permanent tents and structures.

[0005] It is known from patent publication US2005139423 for example to incorporate clip grooves in a dedicated rail structure which is attached to the scaffold using a rail holder with clamping members.

[0006] This prior art card slat roof design generally works well, but there is a continuing need for further improved performance, particularly in terms of cost effectiveness and simplified operation. Summary of the invention

[0007] It would be highly desirable to reduce assembly and disassembly time of temporary protective roofing systems, as well as to improve user-friendliness for roof builders.

[0008] In addition, a particular problem of the prior art temporary protection shed roof system is that it is difficult to achieve the correct angular positioning of the rail holder and the clamp when the rail holder and the clamp are installed on the cylindrical support structure. If the rail holder is not installed correctly, the entire rail structure carrying the shed cloth will be slightly offset and / or tilted relative to the scaffolding, resulting in potential problems with the subsequent installation of the shed cloth in the associated card bar groove. The problem with offset and / or tilted card bar rails is that the lateral distance between adjacent card bar grooves may be too large or too small. Too large a distance between adjacent card bar grooves makes the installation of the shed cloth problematic or even impossible, and too small a distance between adjacent card bar grooves leads to undesirable recesses in the shed cloth. Recesses are generally undesirable due to the problem that water / ice / snow may be collected and suddenly released, or due to the noise generated by flapping the shed cloth. The problem is further increased when the card bar rail deviates from the supporting structure below, because even a small angular error can cause a large lateral offset of the card bar rail.

[0009] The problem is further exacerbated by unwanted movement of the clamps caused by the roofer when the roofer applies torque to the clamping means, such as threaded members.

[0010] In other words, incorrect angular assembly position of the guide rail holder is prone to occur and usually results in less than smooth installation of the shed cloth, and correction of the angular assembly position of the guide rail holder after final installation of the scaffolding or shed roof beams takes time and is potentially dangerous for shed roof builders to climb.

[0011] Therefore, there is a need for a temporary protective roof system with further improved properties, in particular with regard to cost-effective installation and removal and simplified handling. The object of the present disclosure is to provide a temporary protective roof system in which the aforementioned problems are avoided. This object is achieved at least in part by the features of the independent claim. The dependent claims contain further improvements to the temporary protective roof system.

[0012] According to a first aspect of the present disclosure, a temporary protective roof system is provided, which includes: a first roof supporting beam, which is configured to provide primary support and strength to the roof; a first shed cloth; a first elongated guide rail structure, which has a shed cloth attachment joint for attaching the first shed cloth to the first elongated guide rail structure, and a guide rail retainer for detachably fastening the first elongated guide rail structure to the first roof supporting beam; wherein the guide rail retainer of the first elongated guide rail structure includes at least two movable locking pins for disconnectably engaging with the first roof supporting beam.

[0013] According to a second aspect of the present disclosure, a method for assembling a temporary protective roof system is provided, the method comprising: providing a first roof supporting beam; providing a first elongated guide rail structure having a shed cloth attachment joint and a guide rail retainer; fastening the first elongated guide rail structure to the first roof supporting beam in a detachable manner by engaging at least two movable locking pins of the guide rail retainer with the first roof supporting beam; and assembling the first shed cloth on the first elongated guide rail structure by attaching the first shed cloth to the shed cloth attachment joint of the first elongated guide rail structure.

[0014] According to a third aspect of the present disclosure, a method for assembling a temporary protection roof system is provided, the method comprising: providing a first roof support beam and a second roof support beam; providing a first elongated guide rail structure and a second elongated guide rail structure, each having a shed cloth attachment joint and a guide rail retainer; fastening the first elongated guide rail structure to the first roof support beam in a detachable manner by engaging at least two movable locking pins of the guide rail retainer with the first roof support beam, and fastening the second elongated guide rail structure to the second roof support beam by engaging at least two movable locking pins of the guide rail retainer with the second roof support beam. The rail structure is fastened to the second roof support beam in a detachable manner; the first roof support beam and the second roof support beam are arranged to be spaced side by side, and the first roof support beam and the second roof support beam and / or the first elongated guide rail structure and the second elongated guide rail structure are interconnected using brazing elements and / or cross bars to define a rigid roof grid; and the first shed cloth is assembled on the first elongated guide rail structure and the second elongated guide rail structure by attaching the first shed cloth to the shed cloth attachment joint of the first elongated guide rail structure and attaching the first shed cloth to the shed cloth attachment joint of the second elongated guide rail structure.

[0015] In this way, due to the presence of at least two movable locking pins in the guide rail holder configured for engagement with the first roof support beam, the correct angular position of the guide rail holder can be easily, quickly and reliably obtained. Furthermore, the form-fitting locking caused by the locking pins and the corresponding locking structures in the roof support beam also ensures that the guide rail holder does not move or become tilted over time, for example due to large loads, thereby ensuring a reliable assembly position over time.

[0016] Additionally, the removable locking pin design also enables simplified installation of the rail holder on the roof support beam, as operation of the locking pin can be performed manually, thereby making the use of tools such as wrenches to tighten prior art threaded clamps obsolete. Tool-free assembly of the elongated rail is highly advantageous as it makes installation and removal faster and easier, as well as eliminating the risk of the roofer dropping tools in potentially problematic locations.

[0017] Other advantages are achieved by implementing one or several of the features of the dependent claims. For example, in some example embodiments, the shed cloth attachment joint of the first elongated guide rail structure includes a first clip groove, and the first shed cloth has a rectangular form with opposite first and second side edges, the first shed cloth has a first clip chord positioned along the first side edge and a second clip chord positioned along the second side edge, and the first clip chord is configured to be inserted into the first clip groove of the first elongated guide rail structure and can be slidably moved in the first clip groove. The clip design is attractive because it enables the shed cloth to be quickly and flexibly installed and removed from the shed roof support beam, and the shed cloth can be reused multiple times before being discarded.

[0018] However, in some example embodiments, the shed cloth attachment interface of the first elongated rail structure comprises an elongated nail strip fastened to the top side of the first elongated rail structure, wherein the first shed cloth has a rectangular form with opposite first and second side edges, and wherein the first shed cloth is configured to be nailed to the nail strip. This type of shed cloth attachment can be used with almost all types of shed cloths, thereby allowing design flexibility, but the shed cloth is penetrated by nails or staples during assembly, thereby reducing the service life of the shed cloth. On the other hand, shed cloths with less density and lower material thickness can be used.

[0019] In some example embodiments, which may be combined with any one or more of the above embodiments, at least two movable locking pins of the guide rail holder are arranged for disconnectably engaging with corresponding holes or recesses in the first roof support beam. The holes, and sometimes also the recesses, typically provide support for the locking pins in more directions, thereby providing a more clearly defined and reliable locking position.

[0020] In some example embodiments that may be combined with any one or more of the above embodiments, at least two movable locking pins are capable of moving between an engaged position and a disengaged position, wherein the locking pins engage with the first roof support beam for securing the guide rail retainer to the first roof support beam, and wherein the locking pins do not engage with the first roof support beam and the guide rail retainer is capable of being removed from the first roof support beam.

[0021] In some example embodiments, which may be combined with any one or more of the above embodiments, at least two movable locking pins are spring-loaded toward the engaged position.This simplifies the installation of the guide rail holder on the roof support beam.

[0022] In some example embodiments, which may be combined with any one or more of the above embodiments, at least two movable locking pins are configured to engage opposite sides of the first roof support beam. This provides a secure and reliable connection for the roof support beam.

[0023] In some example embodiments that may be combined with any one or more of the above embodiments, the guide rail holder has a foot configured to contact the first roof support beam, and wherein at least two movable locking pins are located in the foot. The foot can increase the stability of the connection between the guide rail holder and the roof support beam.

[0024] In some example embodiments that may be combined with any one or more of the above embodiments, at least one movable locking pin, in particular each of the at least two movable locking pins, is coupled to a common or separate control arm for enabling movement control of the movable locking pin between an engaged position and a disengaged position by manually operating the control arm. The control arm enables, for example, manual operation of the locking pin, thereby providing simplified and more user-friendly manipulation during installation and removal.

[0025] In some example embodiments that can be combined with any one or more of the above embodiments, at least one movable locking pin, in particular each of the at least two movable locking pins, can be selectively set and / or locked in the engaged position and the disengaged position by manually rotating a control arm. The rotation of the control arm is generally associated with user-friendly and safe manipulation of the locking pin.

[0026] In some example embodiments that may be combined with any one or more of the above embodiments, the rail holder and the first roof support beam are configured to provide automatic attachment of the rail holder to the first roof support beam when the rail holder is pushed toward the first roof support beam. This provides further improved user-friendliness for the installation of the temporary protective roof.

[0027] In some example embodiments that may be combined with any one or more of the above embodiments, at least a front region of the at least two locking pins has a tapered or tapered shape over a portion of the total length of the locking pins, such that the tapered or tapered front region of the locking pins is configured to interact with the first roof support beam in the engaged position of the movable locking pin. The tapered locking pins can eliminate play, thereby further improving the connection between the guide rail holder and the roof support beam.

[0028] In some example embodiments that may be combined with any one or more of the above embodiments, at least a portion of at least two locking pins has a cylindrical shape with a diameter in the range of 4 mm to 25 mm. Too small a locking pin may not provide sufficient security, while too large a locking pin may result in increased costs and reduced load capacity of the roof support beam due to the large locking hole.

[0029] In some example embodiments that may be combined with any one or more of the above embodiments, the contact surface of the foot of the first roof support beam configured to receive the guide rail holder is rounded or inclined, so that the locking pin is configured to be automatically pushed back against the force of the spring device when the foot is pushed toward the first roof support beam and the locking pin begins to engage the outer surface of the first roof support beam, and the locking pin is configured to automatically move forward toward the first roof support beam when the foot with the locking pin reaches the final position. This provides further improved user-friendliness for the installation of the temporary protective roof.

[0030] In some example embodiments that can be combined with any one or more of the above embodiments, the foot has a contact surface configured to contact the first roof support beam when the foot reaches the final position, and wherein the contact surface of the foot is positioned at a distance of at least 10 cm, in particular at least 25 cm, and more in particular in the range of 10 cm to 150 cm from the clip groove. This reduces the risk of damage and wear caused by contact between the awning cloth and the brazing elements of the finished clip roof.

[0031] In some example embodiments, which may be combined with any one or more of the above embodiments, the guide rail holder having at least two spring-loaded locking pins is arranged to have a snap-fit ​​function. This provides further improved user-friendliness for the installation of the temporary protective shed roof.

[0032] In some example embodiments that may be combined with any one or more of the above embodiments, the first roof support beam is a lattice girder having a top chord, a bottom chord, and a plurality of interconnecting elements fastened to the top chord and the bottom chord and arranged to transfer loads between the top chord and the bottom chord. The lattice girder is a cost-effective and light-weight design for the roof support beam, and the top chord and the bottom chord provide a good joint for connection with the rail holder.

[0033] In some example embodiments that may be combined with any one or more of the above embodiments, the first roof support beam is a lattice girder having a top chord, a bottom chord, and a plurality of interconnecting elements fastened to the top chord and the bottom chord and arranged for transferring loads between the top chord and the bottom chord, and wherein a central axis of each locking hole is oriented substantially perpendicular to a plane defined by the interconnecting elements. This provides a good distribution of contact points of the guide rail retainer on the top / bottom chord.

[0034] In some example embodiments that may be combined with any one or more of the above embodiments, each of the top chord and the bottom chord is made of a hollow cylindrical tube.Lattice girders are a cost-effective and lightweight design for roof support beams.

[0035] In some example embodiments that may be combined with any one or more of the above embodiments, the rail retainer comprises 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 configured for rigid connection with a first elongated rail structure, and wherein the second end of the beam is provided with a foot for detachably connecting with a first shed roof support beam. The elongated beam is a cost-effective design for achieving a desired vertical distance between the shed cloth and the brazing element.

[0036] In some example embodiments that may be combined with any one or more of the above embodiments, the foot has a load bearing portion with a contact surface configured to abut and transfer loads to an upper chord of a first roof support beam when the foot is mounted on the first roof support beam, and wherein the foot also has a first rigid side portion and a second rigid side portion configured to extend partially over the sides of the upper chord and to hold a locking pin. This provides a good distribution of contact points of the rail retainer on the top / bottom chords.

[0037] In some example embodiments that may be combined with any one or more of the above embodiments, the load bearing portion of the foot is made of a sheet metal that has been bent to have a U-shape, wherein the elongated beam of the rail holder is attached to the outer side of the bottom portion of the U-shaped sheet metal part, and the contact surface is defined by the end edges of the lateral sides of the U-shaped sheet metal part, and wherein the lateral sides are offset from each other by a distance of 40 mm to 250 mm. This enables a cost-effective, stable and rigid connection between the rail holder and the roof support structure.

[0038] In some example embodiments, which may be combined with any one or more of the above-mentioned embodiments, the first elongated guide rail structure is removably fastened to the first roof support beam by means of a plurality of individual guide rail retainers, in particular at least six individual guide rail retainers, which are positioned to be spaced apart along the length of the first elongated guide rail structure.

[0039] In some example embodiments that may be combined with any one or more of the above embodiments, the foot includes a brazing element attachment joint on each side of the foot for enabling the structural brazing element to be attached to the foot. This further increases the modularity of the temporary protective roof system and allows the roof builder to adjust the roof strength according to size and other conditions.

[0040] In some example embodiments that may be combined with any one or more of the above-described embodiments, the brazing element attachment joint of each foot also includes a flat support surface located on each side of the foot for engaging the brazing element, thereby providing increased stability and improved steering for the brazing element of the finished shed roof support structure when the brazing element is assembled on the foot.

[0041] In some example embodiments that may be combined with any one or more of the above embodiments, the first elongated rail structure comprises a plurality of elongated rail sections connected end to end to form the first elongated rail structure, and wherein 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 support beam, in particular to the vertical upper side or lower side of the first roof support beam.

[0068] 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 various aspects described are not limited to the specific illustrated embodiments, but are applicable to other variations of the disclosure.

[0069] Figure 1A and Figure 2 A perspective view of a temporary protection roof system in the form of a card strip roof system according to the present disclosure is schematically shown, wherein: Figure 1Ashows the assembled roof support structure 1 before a set of shed fabrics are installed, and Figure 2 The assembled roof support structure 1 after the set of awning fabrics is installed is shown. The assembled and installed card strip roof system can be considered to have extensions in the roof width direction 25, the roof length direction 26 perpendicular to the roof width direction 25, and the roof height direction 27 perpendicular to both the roof width direction 25 and the roof length direction 26.

[0070] exist Figure 1A and Figure 2 In an example implementation, Figure 1A The assembled roof supporting structure 1 includes four roof supporting beams 2 to 5 arranged side by side and spaced apart along the length direction 26 of the roof, namely the first roof supporting beam 2, the second roof supporting beam 3, the third roof supporting beam 4 and the fourth roof supporting beam 5, 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 A close-up view of a part of the roof supporting structure 1 in the region of the fourth roof supporting beam 5 is shown.

[0071] One of the main purposes of the roof support structure 1 is to span the space above the room and carry and hold the shed cloth in a desired position and to be able to withstand loads transferred from the shed cloth to the roof support structure 1 and caused by, for example, wind, snow loads, etc.

[0072] Figure 2 The finished temporary protection roof system comprises a roof ridge region 13, a first eaves region 18 and a second eaves region 19. The portion of the roof between the roof ridge region 13 and the first eaves region 18 or the second eaves region 19 can be referred to as an intermediate region 20.

[0073] Adjacent roof support beams 2 to 5, such as 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 compartment areas 10 , 11 , 12 .

[0074] exist Figure 2 In the exemplary embodiment, the first shed cloth 15 is installed by the first shed roof builder 23 and the second shed roof builder 24 to cover the first shed roof bay area 10, and the first shed roof builder 23 and the second shed roof builder 24 cooperate to use two pull ropes 14 to jointly pull and install the first shed cloth 15 on the shed support structure. The second shed cloth 16 has been installed to cover the second shed roof bay area 11, and the third shed cloth 17 has been installed to cover the third shed roof bay area 12.

[0075] exist Figure 2In the example implementation mode, the roof is a mansard roof, but the card strip roof system is also applicable to other types of roof designs, such as a flat roof, a sloping roof, a gable roof, etc.

[0076] The roof has a modular structure, since the roof support structure 1 is made of a plurality of parts that are temporarily connected. For example, each of the roof support beams 2 to 5 may comprise a plurality of straight and / or curved roof support beam units that are connected to one another using, for example, a clamp 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.

[0077] Therefore, depending on the construction of the modular frame, the free span width 7 and the roof height 8 of the final roof can vary greatly. For example, the free span width 7 of the roof can be in the range of 5 meters to 50 meters or more, and the roof height as measured from the vertical support surface at the first or second eaves to the roof ridge can be in the range of 0 meters to 30 meters or more.

[0078] Figure 3A Schematically showing, for example Figure 1A A side view of the first roof support beam 2, wherein: Figure 3B A close-up side view of the curved portion of the first roof support beam 2 is shown, and Figure 3C A close-up side view of a straight portion of a first roof supporting beam 2 is shown. Figure 3A The roof support beams 2 stand upright on the support surface 47.

[0079] Figure 4 For example, a perspective view of a first roof support beam 2 is shown with its bent section.

[0080] The roof support beams 2 to 5 can have different structures, compositions and designs. A particularly attractive design of the roof support beams 2 to 5 is in the form of lattice beams, lattice girders or truss girders because of their high structural strength combined with low weight. Such lattice girders or truss girders can be made using steel, aluminum or other types of metal. The lattice girder or truss girder - sometimes also called a venter girder - typically includes a top chord 59, a bottom chord 60 and a plurality of relatively straight structural elements 61, which interconnect the top and bottom chords and form a generally triangular system.

[0081] Reference FIG. 3A to FIG. 3C and Figure 4According to some example embodiments, the first roof support beam 2 carries a removable first elongated rail structure 30 having a shed cloth attachment joint 96 for attaching the first shed cloth 15 to the first elongated rail structure 30. This design further increases the modularity of the temporary protective roof system, because the roof support beam 2 can be any type of roof support beam, and not necessarily a dedicated roof support beam with an integrated shed cloth attachment joint. Therefore, scaffolding and / or protective roof system suppliers can use already available roof support beams as load carrying members, or can use almost any type of roof support beam, thereby reducing the cost and complexity of increasing the scope of services to include a temporary protective roof system.

[0082] 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 component according to the European standard EN 12810-1 for scaffolding products, i.e. for building facade scaffolding etc. In order to further improve the compatibility with other components of the scaffolding system, 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.

[0083] Furthermore, in the event that, for example, the shed cloth attachment joint 96 of the first elongated rail structure 30 is damaged, it is not necessary to replace the entire shed roof support beam, but it is sufficient to replace the first elongated rail structure 30 .

[0084] Since the detachable first elongated guide rail structure 30 is carried by the rigid and load-bearing first roof support beam 2, the first elongated guide rail structure 30 can be designed without any substantial requirements in terms of load capacity. In other words, the first elongated guide rail structure 30 can be designed to have relatively low rigidity to reduce weight and save costs.

[0085] According to at least FIG. 3A to FIG. 8D In the exemplary embodiment of the present invention, the shed cloth attachment joint 96 for attaching the first shed cloth 15 to the first elongated guide rail structure 30 may be realized in the form of at least the first clip groove 31 .

[0086] 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 profile in a polymer extrusion process.

[0087] The first elongated rail structure 30 may be manufactured in one piece or comprise multiple components and / or pieces of material.

[0088] The first clamping groove 31 obviously extends parallel to the extension direction of the first guide rail structure 30 .

[0089] According to some example embodiments, the first elongated rail structure 30 includes a plurality of separate and distributed 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 integrally formed within the first elongated rail structure 30, and are configured to enable the first elongated rail structure 30 to be quickly and securely temporarily attached to the first roof support beam 2 by the roof builders 23, 24.

[0090] Reference Figure 4 , a quick and secure temporary attachment of the first elongated guide rail structure 30 to the first roof supporting beam 2 can be achieved by providing two movable locking pins for each of the guide rail retainers 35 of the first elongated guide rail structure 30 to engage with corresponding holes in the top chord 59 of the first roof supporting beam 2 in a disconnectable manner.

[0091] Figure 7 A awning cloth, for example the first awning cloth 15 , is schematically shown in a top view. The first awning cloth 15 comprises a first shuttle device 40 , a second shuttle device 41 , a third shuttle device 42 and a fourth shuttle device 43 , each of which is arranged in a separate corner of the first awning cloth 15 . Figure 7 Also shown are four pull ropes 14 connected to each of the first to fourth shuttle devices 40 to 43 .

[0092] Reference Figure 2 and Figure 7 The first awning cloth 15 may be in the form of a rectangle having opposite first and second side edges 28, 29 and opposite third and fourth side edges 36, 37, wherein the first awning cloth 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.

[0093] Figure 5 A perspective view schematically shows a first shed cloth 15 and a second shed cloth 16 in an assembled state together with a first elongated guide rail structure 30, wherein a first shuttle device 40 is attached to the first shed cloth 15 and connected to the pull rope 14, and wherein a second shuttle device 41 is attached to an adjacent second shed cloth 16 and connected to the pull rope 14. Figure 5 Also shown is a rail holder 35 with an associated rail holder foot 9 which is designed for detachable fastening to the first roof support beam 2 .

[0094] Reference Figure 5When the first shed cloth 15 is mounted on the first elongated guide rail structure 30, the first clip chord 38 of the first shed cloth should be more or less completely slidably inserted into the first clip groove 31 of the first elongated guide rail structure 30 to provide a firm and sealed connection between the first side edge 28 of the first shed cloth and the first elongated guide rail structure 30.

[0095] The installation of the first awning cloth 15 on the first elongated guide rail structure 30 is performed, for example, by the shed builder inserting the end of the first clip chord 38 of the first awning cloth 15 into the end of the first clip groove 31 of the first elongated guide rail structure 30. This can be performed manually, for example. Thereafter, a pulling force is applied to the first awning cloth 15 to slide the first clip chord 38 into the first clip groove 31 until the desired position is reached. The pulling force is applied to the first awning cloth 15, for example, via the pull rope 14 of the first shuttle device 40.

[0096] Figure 6 An example of a cross-sectional view of an example embodiment of a first elongated rail structure 30 is shown, which has a first shed cloth 15 installed in a first clip groove 31 of the first elongated rail structure 30 and a second shed cloth 16 installed in a third clip groove 33 of the first elongated rail structure 30.

[0097] The first elongated guide rail structure 30 is not limited to this specific design, and may alternatively have two clip grooves or six clip grooves, etc.

[0098] exist FIG. 8A to FIG. 8D The basic steps for installing a single awning unit are schematically illustrated in FIG. Fig. 8A Before starting to install the first awning cloth 15, the roof support structure 1 with its roof support beams 2 to 5 and the brazing elements 6 is installed. This can be performed, for example, by first building the roof compartments in a convenient location, such as on the ground close to the desired final location, then lifting the finished roof compartments to the desired final location using a crane or the like, and finally connecting the roof compartments using brazing elements. A roof compartment refers to two roof support beams connected to each other by a brazing element to form a rigid entity. Alternatively, a single roof support beam can be assembled, then lifted to the desired final location, and then connected to adjacent roof support beams using brazing elements 6.

[0099] All necessary guy ropes are fixed in the rope guide structure 52 when the roof sections are erected on the ground and before lifting, because the pre-placed guy ropes 14 avoid unnecessary climbing on the assembled roof support structure 1.

[0100] When the awning cloth has not yet been placed, the installation, lifting and fixing of the roof support structure 1 with its roof support beams 2 to 5 and the brazing elements 6 are simplified due to the reduced sensitivity to wind, and it is easier to climb up the roof support structure to connect adjacent roof support beams before installing the awning cloth 15, 16.

[0101] Reference Figure 8B When the roof support structure 1 with its roof support beams 2 to 5 and brazing elements 6 is completed, the installation of the first shed cloth 15 can begin. This can be performed by first placing the first shed cloth 15 at a position close to, for example, the first eaves area 18, then inserting the ends of the first clip chord rods 38 and the second clip chord rods 39 of the first shed cloth 15 into the appropriate clip grooves 31 to 34 of the first elongated guide rail structure 30 and the second elongated guide rail structure 62, and connecting the pre-placed pull rope 14 with the first shuttle device 40 and the second shuttle device 41. Note 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 awning cloth 15.

[0102] Afterwards, refer to Figure 8C and Fig.8D The shed builders 23 and 24 located in the second shed eaves area 19 can manually pull the pull rope 14 connected to the first shuttle device 40 and the second shuttle device 41 to install the first shed cloth 15 until the first shed cloth 15 covers the entire first shed roof space area 10. Fig.8D as shown in .

[0103] Fig. 9 and 10A to Fig. 10C An exemplary embodiment of the foot 9 of the guide rail holder 35 is schematically shown, wherein: Fig. 9 A perspective view of the guide rail holder 35 with the foot 9 is shown when approaching the first roof support beam 2 having two locking holes 67 or recesses, Fig. 10A shows a side view of the same location, Fig. 10B The foot 9 is shown after its contact surface 66 has come into contact with the outer surface of the first roof support beam 2, but before its two locking pins 68 are inserted into the associated locking holes 67 or recesses of the first roof support beam 2, and Fig. 10C 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 .

[0104] Therefore, in some example embodiments, the first roof support beam 2 is a lattice beam having a top chord 59, a bottom chord 60 and a plurality of interconnecting elements 61, which are fastened to the top chord and the bottom chord and are arranged to transfer loads between the top chord and the bottom chord, and wherein locking holes 67 are provided in the top chord 59 and / or the bottom chord 60.

[0105] Furthermore, in some example embodiments, the central axis of each locking hole 67 is oriented substantially perpendicular to a plane defined by the interconnecting element 61 , ie, does not deviate by more than 25 degrees from a plane perpendicular to the plane defined by the interconnecting element 61 .

[0106] Each of the top and bottom chords may be made, for example, from a hollow cylindrical tube, from which a highly accurate locking hole 67 can be drilled or punched with a low level of tolerance.

[0107] The guide rail holder 35 therefore has a foot 9 which is configured for contact with the first roof support beam 2 and in which two movable locking pins 68 are located.

[0108] exist Fig. 9 and FIG. 10A to FIG. 10C In the exemplary embodiment of FIG. Fig. 10C The locked and engaged positions shown in FIG. 6 are spring loaded, but the locking pin 68 can be selectively set in a stable open state and closed state by pulling the control arm 69 outward to remove the locking pin 68 from the locking hole 67 and then rotating the two control arms 69 to set the locking pin 68 in a stable disengaged position.

[0109] Alternatively, for additional safety, the locking pin 68 can be fixed in the engaged position by finally rotating the control arm into the engaged position. In this case, the locking pin 68 can be converted from the engaged state to the stable disengaged state by first rotating the two control arms 69, for example, 90 degrees, pulling the control arms 69 outward against the spring force of the spring-loaded spring to pull the locking pin 68 out of the locking hole 67, and then rotating the two control arms 69, for example, 90 degrees to set the locking pin 68 in the stable disengaged position.

[0110] Each of the two movable locking pins 68 is therefore coupled to a common or separate control arm 69 for enabling movement control of the movable locking pin between the engaged position and the disengaged position by manual operation of said control arm 69 .

[0111] Furthermore, each of the at least two movable locking pins 68 may be selectively set and / or locked in an engaged position and a disengaged position by manually rotating a control arm 69 .

[0112] The two movable locking pins 68 are thus able to move between an engaged position and a disengaged position, in which the locking pins engage in holes 67 in the first roof support beam 2 to fix the guide rail retainer to the first roof support beam 2, and in the disengaged position, the locking pins are not engaged in holes 67 and the guide rail retainer can be removed from the first roof support beam 2.

[0113] When moving between the disengaged position and the engaged position, the movable locking pin 68 is able to move in a direction toward the first roof support beam 2 and in a direction away from the first roof support beam 2. In particular, the movable locking pin 68 can be linearly moved within a plane located within a range of + / -30 degrees from a direction perpendicular to the first roof support beam 2. When the locking pins have an elongated or cylindrical shape, each movable locking pin can be moved along the extension direction or axial direction of the locking pin 68.

[0114] The two movable locking pins 68 are configured to engage opposite sides of the first roof support beam 2. Furthermore, the two movable locking pins 68 may be arranged to be substantially aligned with each other, or at least offset from each other by no more than 30 degrees.

[0115] exist Fig. 10B In an example embodiment, the guide rail retainer 35 includes an elongated beam having a first end 44 and a second end 46, wherein the first end 44 of the beam is provided with a guide rail attachment joint 45 configured to be rigidly connected to the first elongated guide rail structure 30, and wherein the second end 46 of the beam is provided with a foot 9 for being detachably connected to the first roof support beam 2.

[0116] The foot 9 has a load-bearing portion 20, which has a contact surface 66 configured to abut the top chord 59 of the first roof support beam 2 and transfer the load to the top chord 59 when the foot 9 is fixed on the first roof support beam 2, and wherein the foot 9 also has a first rigid side portion 76 and a second rigid side portion 77, which are configured to extend partially above the sides of the top chord 59 and are used to hold the locking pin 68.

[0117] For example, refer to Figure 5 , the load-bearing part of the foot 9 is made of a metal sheet 78 that has been bent into a U-shape, wherein the elongated beam of the guide rail retainer 35 is attached to the outer side of the bottom part of the U-shaped metal sheet part 78, and the contact surface is defined by the end edges of the lateral sides of the U-shaped metal sheet part 78, and wherein the lateral sides are offset from each other by a distance 79 of 40 mm to 250 mm.

[0118] The locking pins 68 may have a slightly tapered shape so that at least the tapered portion of each locking pin 68 may interact with the locking hole or recess 67 for ensuring increased stability and eliminating play.

[0119] The reliable and accurate angular positioning of the foot 9 on the first roof support beam 2 provided by the play-free engagement of the locking pin 68 with the locking hole 67 ensures that adjacent rail retainers 35 are mounted parallel to each other in the roof length direction 26. Therefore, the distance between the clip grooves of the adjacent first and second elongated rail structures 30 and 62 can be almost constant or at least within a relatively tight tolerance range over the length of the first and second elongated rail structures 30 and 62, making it easier to install and remove the shed cloths 15 to 17 in the clip grooves.

[0120] As described in other aspects, when adjacent guide rail retainers 35 are not installed parallel to each other, that is, slightly inclined relative to each other, the distance between the clamping grooves of the adjacent first elongated guide rail structures 30 and the second elongated guide rail structures 62 is too small or too large, thereby making the installation / disassembly of the awning cloth more difficult.

[0121] Referring to the schematic diagram below FIG. 11A to FIG. 11C Describing another example embodiment of the foot 9, FIG. 11A to FIG. 11C A foot 9 is shown with a double spring-loaded locking pin 68 provided with a snap-fit ​​function. In other words, the locking pin 68 is always pushed forward to an inwardly protruding position by default with the aid of a mechanical spring device 70, such as Fig.11A as shown in .

[0122] As depicted by the foot movement arrow 73, when the foot is pushed toward the roof support beam 2, the locking pin 68 is temporarily automatically retracted to the retracted position. Specifically, due to contact with the outer rounded surface 80 of the roof support beam 2, the push causes the locking pin 68 to be automatically temporarily retracted, as shown in FIG. Fig. 11B as shown in .

[0123] When the foot 9 moves further toward the roof support beam 2, the contact surface 66 of the 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 foot 9 and the guide rail holder 35 are firmly and reliably connected to the roof support beam 2, as shown in FIG. Fig. 11C as shown in .

[0124] In other words, in some example embodiments, the rail holder 35 and the first roof supporting beam 2 are configured to provide automatic attachment of the rail holder 35 to the first roof supporting beam 2 when the foot 9 of the rail holder 35 is pushed toward the first roof supporting beam 2 .

[0125] In addition, the contact surface 80 of the first roof support beam 2 configured to receive the foot of the guide rail retaining member 35 is rounded or inclined, so that the locking pin 68 is configured to be automatically pushed back against the force of the spring device when the foot 9 is pushed toward the first roof support beam 2 and the locking pin 68 begins to engage the outer surface 80 of the first roof support beam 2, and so that the locking pin 68 is configured to automatically move forward into the locking hole 67 of the first roof support beam 2 when the foot with the locking pin 68 reaches the final position.

[0126] In particular, refer to FIG. 11A to FIG. 11C , the front end 71 of the locking pin 68 may have a slightly tapered shape to ensure increased stability and eliminate play.

[0127] Fig. 12A A perspective view of an example embodiment of a locking pin 68 is schematically shown, and Fig. 12B A side view of the locking pin 68 is schematically shown.

[0128] The front region 81 of the two locking pins 68 may have a conical or tapered shape over a portion 82 of the total length 83 of the locking pin 68 , for example at least 3 mm, so that the conical or tapered front region 81 of the locking pin 68 is configured to interact with the locking hole or recess 67 .

[0129] Additionally, the cylindrical portion 84 of the locking pin 68 may have a diameter within a range of 4 mm to 25 mm.

[0130] The locking pin is initially described herein as being primarily cylindrical, but the locking pin 68 may have other cross-sectional shapes.

[0131] In some example embodiments, the foot 9 of the guide rail retainer 35 may include at least two spring-loaded locking pins 68 for removably engaging with corresponding holes 67 located in the first roof support beam 2 to safely and securely connect the guide rail retainer 35 and the associated first elongated guide rail structure 30 to the first roof support beam 2.

[0132] The guide rail holder is then removed by, for example, manually pushing the two spring-loaded locking pins 68 backwards and simultaneously lifting the foot and rail holder away from the support beam 2. FIG. 11A to FIG. 11C The snap-fit ​​foot 9.

[0133] Therefore, refer to Figures 1A to 12BThe present disclosure relates to a card-strip roof system, which includes: a first roof support beam 2, the first roof support beam 2 is configured to provide primary support and strength for the roof; a first elongated guide rail structure 30, the first elongated guide rail structure 30 having a first card-strip groove 31 and a guide rail retainer 35 for removably fastening the first elongated guide rail structure 30 to the first roof support beam 2; a first shed cloth 15, the first shed cloth 15 is in the form of a rectangle with opposite first and second side edges, wherein the first shed cloth 15 has a first card-strip chord 38 positioned along the first side edge and a second card-strip chord 39 positioned along the second side edge, and wherein the first card-strip chord 38 is configured to be inserted into the first card-strip groove 31 of the first elongated guide rail structure 30 and be able to slide therein, wherein the guide rail retainer 35 of the first elongated guide rail structure 30 includes at least two movable locking pins 68 for disconnectable engagement with corresponding holes 67 in the first roof support beam 2.

[0134] Refer again Figures 1A to 12B The card-strip roof system also includes: a second roof supporting beam 3, the second roof supporting beam 3 is configured to provide primary support and strength for the roof; a second elongated guide rail structure 62, the second elongated guide rail structure 62 having a first card-strip groove 31 and a guide rail retainer 35 for removably fastening the second elongated guide rail structure 62 to the second roof supporting beam 3; wherein the first roof supporting beam 2 and the second roof supporting beam 3 are configured to be positioned side by side and spaced apart and connected to each other by means of brazing elements and / or cross bars 6 to define a rigid roof grid; wherein the second card-strip chord 39 of the first shed cloth 15 is configured to be inserted into the first card-strip groove 31 of the second elongated guide rail structure 62 and to be able to slide therein; and wherein the guide rail retainer 35 of the second elongated guide rail structure 62 includes at least two movable locking pins 68 for disconnectably engaging with corresponding holes 67 in the second roof supporting beam 2.

[0135] The above-described embodiment includes two movable locking pins 68 of the guide rail holder 35 that engage within corresponding locking holes 67 of the top chord 59 or the bottom chord 60. However, the two movable locking pins 68 may alternatively engage other portions of the first roof support beam 2 while still providing acceptable connection strength and stability between the guide rail holder 35 and the first roof support beam 2.

[0136] For example, refer to Fig.13A and Fig. 13B The top chord 59 and / or the bottom chord 60 may have at least two elongated recesses 67 extending over the entire length of the chords 59, 60, or over a portion of the length of the chords. The recesses 67 may be arranged, for example, on substantially opposite sides of the top chord 59 and / or the bottom chord 60. Fig.13A A perspective view of the top chord 59 is shown, and Fig. 13B A cross-sectional view is shown showing the foot 9 in engagement with the top chord 59 .

[0137] Specifically, Fig. 13B At least two movable spring-loaded locking pins 68 are shown engaging in two elongated recesses 67 of the first roof support beam 2 .

[0138] In those embodiments where the location of attachment of the guide rail retainer 35 to the roof support beam 2 is not important, FIG. 13A to FIG. 13B The embodiment provides increased flexibility because the rail retainer 35 can be disconnectably engaged at any position along the length of the roof support beam 2.

[0139] However, in those embodiments where the attachment position of the guide rail holder 35 on the roof support beam 2 needs to be predefined or even locked in the length direction of the roof support beam, some type of longitudinal locking structure may be required. For example, the foot 9 can be provided with a protrusion 99 or the like, which is configured to be engaged in a corresponding hole or recess 100 in the top chord 59 and / or the bottom chord 60 to provide the desired locked position of the guide rail holder 35 in the length direction of the roof support beam 2.

[0140] exist Fig.14 , in which the top chord 59 and / or the bottom chord 60 have a form that enables two movable locking pins 68 of the guide rail holder 35 to reliably engage on the back of the top chord 59 and / or the bottom chord 60. In other words, the cross-section of the top chord 59 and / or the bottom chord 60 is selected to provide an abutment surface against which the two movable locking pins 68 can apply pressure to clamp the foot 9 on the top chord 59 and / or the bottom chord 60.

[0141] Fig.14 A cross-sectional view is shown showing the foot 9 in engagement with the top chord 59, which in this example embodiment is D-shaped with a rounded outer surface 101 facing the first elongated rail structure 30 and an at least partially substantially flat outer surface 102 facing the interconnecting element 61 of the roof support beam 2. Thus, the two movable locking pins 68 of the rail retainer 35 can be reliably engaged at the back of the top chord 59 without the need to drill potentially weakened locking holes in the upper chord. Other forms and shapes of the top chord 59 and / or the bottom chord 60 are of course possible.

[0142] As mentioned above FIG. 13A to FIG. 13BThe same issues discussed above regarding positioning and / or locking of the rail retainer 35 in the lengthwise direction of the roof support beam 2 also apply here. Therefore, if it is desired to lock the foot 9 in the lengthwise direction, the foot 9 may be provided with a protrusion 99 (not shown) or the like configured to engage in a corresponding hole or recess 100 (not shown) in the top chord 59 and / or the bottom chord 60.

[0143] exist FIG. 15A to FIG. 15B Another example of the attachment of two movable locking pins 68 to the top chord 59 or the bottom chord 60 is schematically illustrated in FIG. Fig.15A A perspective view of the top chord 59 is shown, and Fig. 15B A cross-sectional view is shown showing the foot 9 in engagement with the top chord 59 .

[0144] In this example embodiment, the top chord 59 of the roof support beam 2 is provided with a dedicated locking pin receiving structure 103. The locking pin receiving structure 103 can be, for example, welded or otherwise fixed to the roof support beam 2, and the locking pin receiving structure 103 can be arranged so that the two movable locking pins 68 of the guide rail holder 35 can engage with the holes or recesses 67 of the locking pin receiving structure 103 for disconnectable attachment of the guide rail holder 35 to the roof support beam 2.

[0145] exist FIG. 15A to FIG. 15B In the exemplary embodiment of FIG. 5 , the locking pin receiving structure 103 corresponds to two plates welded to the top chord 59 and provided with the locking holes 67. Other forms and shapes of the locking pin receiving structure 103 are of course possible.

[0146] The shed fabric attachment joint 96 of the first elongated rail structure 30 is initially disclosed herein in the form of the clip grooves 31 to 34. However, the benefits of providing the rail retainer 35 with at least two movable locking pins for releasably engaging with the first roof support beam 2 are not limited to the clip groove / chord roof connection. Fig.16 In some example embodiments, the shed cloth attachment joint 96 of the first elongated guide rail structure 30 may include an elongated nail strip 97 fastened to the top side of the first elongated guide rail structure 30, wherein the first shed cloth 15 is in the form of a rectangle having opposite first and second side edges, and wherein the first shed cloth 15 is configured to be nailed to the nail strip 97.

[0147] The elongate spike strip 97 typically extends over the entire length of the first elongate rail structure 30 for providing good flexibility in the attachment locations of the first shed cloth 15 and the second shed cloth 16 .

[0148] Specifically, two adjacent shed cloths, each covering a separate portion of the shed roof in the length direction 26 of the shed roof, may first be spread over the shed roof support structure 1, wherein the respective first side edge 28 and second side edge 29 of the shed cloths overlap at the region of the elongated nail strips 97. Thereafter, the shed roof builder may fasten the first shed cloth 15 and the second shed cloth 16 to the elongated nail strips 97 at a plurality of locations along the length of the first elongated guide rail structure 30 using suitable fasteners 104, such as nails or staples.

[0149] When the temporary protective roof system is subsequently disassembled, the roof builder removes the plurality of fasteners 104, thereby removing the first shed cloth 15 and the second shed cloth 16. Alternatively, in the case where the first shed cloth 15 and the second shed cloth 16 are disposable items, the roof builder can, for example, simply tear off the first shed cloth 15 and the second shed cloth 16 from the elongated nail strips 97.

[0150] Fig.17A A side view of an assembled first roof support beam 2 is schematically shown, wherein the first roof support beam 2 has a first elongated guide rail structure 30 temporarily fastened to the upper side of the first roof support beam 2, and a second elongated guide rail structure 62 temporarily fastened to the lower side of the first roof support beam 2.

[0151] Fig. 17B Schematically shows Fig.17A A side view of an exploded view of the first roof support beam 2. Fig. 17B Thus, an example embodiment of a modular composition consisting of a first roof support beam, a first elongated rail structure 30 and a second elongated rail structure 62 is shown.

[0152] In this example embodiment, the first elongated guide rail structure 30 and the second elongated guide rail structure 62 are of the card bar type, i.e. include card bar grooves, but the modular design described herein is not limited to the card bar type shed cloth attachment joint, and the shed cloth attachment joint can be changed to the nail bar type or any other type.

[0153] The first elongated guide rail structure 30 and the second elongated guide rail structure 62 can have similar or identical designs, that is, similar or identical types and numbers of clip grooves, similar or identical types of rope guide structures 52, so that the same type of shed cloth can be selectively placed in the first elongated guide rail structure 30 or the second elongated guide rail structure 62.

[0154] This type of double placement of the awning cloth above and below the first roof support beam 2 is useful for improving thermal insulation, etc. In addition, if necessary, the card strip roof system can be built with only the second elongated guide rail structure 62, that is, only the lower guide rail structure 62.

[0155] In other words, the first roof support beam 2 may include a plurality of support beam elements 63, which may have various forms, such as straight elements and curved elements, and the desired first roof support beam 2 may therefore be constructed by assembling and fastening a set of appropriate support beam elements 63 to each other.

[0156] Similarly, the first elongated guide rail structure 30 includes a plurality of elongated guide rail segments 64, which are connected end to end and continuous with each other to form the first elongated guide rail structure 30. Similarly, the second elongated guide rail structure 62 also includes a plurality of elongated guide rail segments 64, which are connected end to end and continuous with each other to form the second elongated guide rail structure 62.

[0157] exist Fig. 17B In the example embodiment of FIG. 5 , each of the first elongated rail structure 30 and the second elongated rail structure 62 includes a curved elongated rail segment 64 and a plurality of straight elongated rail segments 64 .

[0158] The straight elongated rail sections 64 of the first elongated rail structure 30 and the second elongated rail structure 62 may be identical, such that the straight elongated rail sections 64 may be fastened to both the upper and lower sides of the first roof supporting beam 2 .

[0159] The curved elongated rail sections 64 of the first and second elongated rail structures 30, 62 are different in that the rail holders 35 used to attach the curved elongated rail sections 64 to the first roof supporting beam 2 are positioned on opposite sides.

[0160] Therefore, in some example embodiments, the first elongated guide rail structure 30 includes a plurality of elongated guide rail segments 64 connected end to end to together form the first elongated guide rail structure 30, and wherein at least one elongated guide rail segment 64 of the first elongated guide rail structure 30 and / or the second elongated guide rail structure 62 includes a guide rail retainer 35, in particular two, three or four guide rail retainers 35, for removably fastening the elongated guide rail segment 64 to the first roof supporting beam, in particular to the vertical upper side or lower side of the first roof supporting beam 2.

[0161] The first elongate rail structure 30 is removably secured to the first roof supporting beam 2 by means of a plurality of individual rail retainers 35 located at intervals along the length of the first elongate rail structure 30 .

[0162] Reference Fig.17AThe guide rail holder 35 has a foot 9 for removably fastening the elongated guide 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 the first roof support beam and bears load relative to the first roof support beam, is positioned to be spaced from the first clip groove 31 by a distance 65 measured in the direction opposite to the extension direction of the elongated guide rail section, the distance 65 being at least 10 cm, specifically at least 25 cm, and more specifically in the range of 10 cm to 150 cm, specifically in the range of 15 cm to 50 cm. This reduces the risk of damage and / or wear of the shed cloth due to interference with the roof support structure 1.

[0163] Reference FIG. 3A to FIG. 3B , Figure 4 and FIG. 17A to FIG. 17B In some example embodiments, the rope guide structure 52 of the first elongated guide rail structure 30 may include at least one independent rope guide member 74, 75 positioned on the elongated guide rail segment 64 or along the first elongated guide rail structure 30, and in particular, two, three, four or five independent rope guide members 74, 75 positioned on the elongated guide rail segment 64 or along the first elongated guide rail structure 30 at longitudinal intervals.

[0164] Reference FIG. 3A to FIG. 3B , Figure 4 and FIG. 17A to FIG. 17B , at least one independent rope guiding member 74 , 75 is positioned on at least one curved elongated guide rail section 64 , and wherein at least one, in particular all, straight elongated guide rail sections 64 are free of the rope guiding structure 52 .

[0165] Reference Figure 4 and FIG. 17A to FIG. 17B The first elongated guide rail structure 30 includes a plurality of independent rope guide members 74, 75 positioned at intervals on the outer side along the height direction of the first elongated guide rail structure 30, and the first elongated guide rail structure 30 includes a plurality of independent rope guide members 74, 75 positioned at intervals on the inner side along the height direction of the first elongated guide rail structure.

[0166] Fig.18A A top view of the first roof support beam 2 and the second roof support beam 3 is shown in the installed state, and two rail holders 35 of the first elongated rail section 30 are installed on each of the first roof support beam 2 and the second roof support beam 3.
