Abstract
Description
Technical Field
[0001] This invention relates to the field of roof panel technology, and in particular to a prefabricated roof panel system. Background Technology
[0002] With the continuous development of society, the construction industry has also been booming. In order to meet different needs, various new building materials have emerged. Prefabricated roof panels are a typical example. They are connected and fixed by combination and assembly, making them more convenient and faster to manufacture, transport and use.
[0003] Reference Figure 1 The existing prefabricated roof panel system has the following construction methods:
[0004] First, install the support 2 on the main steel structure 1 of the roof, and then install the main purlin 3 on the support 2 with screws. The support 2 has a vertical slotted hole, and the screw is confined in the slotted hole. Under this confining condition, the main purlin 3 can move a certain distance in the vertical direction relative to the main steel structure 1.
[0005] Next, an L-shaped connecting seat 5 is installed on the top of the main purlin 3, and a secondary purlin 4 is then installed on the connecting seat 5. The connecting seat 5 has two mutually perpendicular oblong holes, and the limiting screws in the two oblong holes are respectively fixed to the top of the main purlin 3 and the side of the secondary purlin 4. Under the action of the connecting seat 5, the secondary purlin 4 can not only move a certain distance along the length of the main purlin 3, but also move a certain distance in the vertical direction relative to the main purlin 3.
[0006] Finally, the roof panel 6 is fixed on the secondary purlin 4.
[0007] In high-wind-pressure environments, strong winds blowing against the roof panels cause the main and secondary purlins to move, resulting in noise from the relative sliding of screws and slotted holes. Additionally, the thermal expansion and contraction of the metal components also causes movement of the purlins, generating noise. Therefore, venues with high noise reduction requirements need a prefabricated roofing system that produces almost no noise under high wind pressure and during seasons when metal components expand and contract. Summary of the Invention
[0008] The purpose of this invention is to provide a prefabricated roof panel system that aims to solve the problem of noise generated by existing prefabricated roof panel systems under high wind pressure and during seasons when metal products expand and contract with temperature.
[0009] This invention provides a prefabricated roof panel system, including horizontal and vertical purlins fixed to the same plane on the main steel structure, and multiple layers of support mesh distributed vertically. Sound-absorbing material layers and / or sound-insulating material layers are disposed between adjacent layers of the support mesh, and the top layer of the support mesh supports the roof panel; multiple connectors adapted to connect the top layer of the support mesh to the roof panel; and a support mesh tensioning structure located on the horizontal and vertical purlins, the tensioning structure connecting the edges of the support mesh around its perimeter.
[0010] By adopting the above technical solution, since the four edges of the sound-absorbing material layer and the sound-insulating material layer are blocked and limited by the tensioning structure of the supporting net, the sound-absorbing material layer and the sound-insulating material layer will not move relative to the supporting net and generate friction noise under strong wind. Moreover, multiple connectors bind the roof panel to the supporting net. Under strong wind, the movement range of the roof panel is less than the width of one grid of the supporting net. Therefore, the friction noise between the roof panel and the supporting net is very small. Under the action of the sound-absorbing material layer and the sound-insulating material layer, and with the use of smooth silk threads to form the supporting net, the friction noise is almost negligible.
[0011] In summary, this roof panel system innovatively adopts a multi-layer support net to achieve stable arrangement of various functional modules under the roof panel and a firm connection to the roof panel. At the same time, it has the excellent effect of producing almost no noise under high wind pressure and in seasons when metal products will expand and contract with temperature.
[0012] Optionally, the supporting net tensioning structure includes a plurality of winding posts, which are equidistantly distributed along the length direction of the transverse purlins and the longitudinal purlins.
[0013] By adopting the above technical solution, the ends of the threads at the edge of the support net are tied to the winding post. Rotating the winding post tightens the threads, and fixing the winding post keeps the threads taut. After tightening all the threads, the support net is in a taut state.
[0014] Optionally, the supporting mesh tensioning structure further includes collars corresponding to the winding posts, the collars being fixed to the cross purlins and the longitudinal purlins, and the winding posts being fixed inside the collars.
[0015] By adopting the above technical solution, the winding post will not shift its position when rotating inside the collar, and it is also convenient to fix the winding post and collar by means of adhesive or welding.
[0016] Optionally, multiple annular grooves are spaced apart along the axial direction on the winding post, and the threads at the edge of the supporting mesh are wound in the annular grooves.
[0017] By adopting the above technical solution, the wires wound in the annular groove will not slip off along the axial direction of the winding column, and the annular groove defines the position of the wires, so that all the wires woven into a layer of support net can be located in the same plane.
[0018] Optionally, the connector includes an annular buckle and an internally threaded cylinder, the threads of the supporting mesh are threaded through the annular buckle, the bottom end of the internally threaded cylinder is connected to the top of the annular buckle, and the top end is connected to the top of the roof panel.
[0019] By adopting the above technical solution, the ring buckle and the internal threaded cylinder are detachably connected, which facilitates the installation of the connecting body.
[0020] Optionally, the top of the annular buckle is provided with a wire inlet, and threaded bars that are integrally connected to the annular buckle are provided on both sides of the wire inlet. The two threaded bars are threadedly engaged with the bottom end of the internal threaded cylinder.
[0021] By adopting the above technical solution, it is convenient for the wires of the support net to enter the ring buckle from the inlet, and then the inlet is closed when the threaded bar is connected to the ring buckle.
[0022] Optionally, the roof panel includes two edge panels and multiple intermediate panels, with all intermediate panels spliced between the two edge panels; both the edge panels and the intermediate panels include a top panel; one side of the top panel of the intermediate panel is provided with a female assembly end, and the other side is provided with a male assembly end; one side of the top panel of the edge panel is provided with either a female assembly end or a male assembly end, and the other side is provided with an edge seal; the male assembly end of one roof panel can be slidably inserted into the female assembly end of the adjacent roof panel.
[0023] By adopting the above technical solution, the female and male assembly ends are connected by a sliding plug-in joint, which can reduce the width requirement of each roof panel when assembling the roof panels; and after the assembly is completed, by sealing the assembly gaps of most roof panels with glue, a small number of designated roof panels can be moved under strong winds, thereby avoiding the generation of large noise caused by the simultaneous movement of a large number of roof panels under strong winds.
[0024] Optionally, the female assembly end includes a first vertical plate and a C-shaped plate, the top end of the first vertical plate is connected to the top plate, and the bottom end is connected to the C-shaped plate, the opening of the C-shaped plate faces the adjacent roof panel; the male assembly end includes a second vertical plate and a J-shaped plate, the top end of the second vertical plate is connected to the top plate, and the bottom end is connected to the J-shaped plate, the J-shaped plate is inserted into the C-shaped plate of the adjacent roof panel.
[0025] By adopting the above technical solution, a lateral sliding plug-in connection between the female and male assembly terminals is achieved.
[0026] Optionally, the roof panel further includes a side sealing plate, which is located on an adjacent side of the roof panel, and the side sealing plate is provided with a protrusion, which is fixedly connected to the lower surface of the roof panel; a joint sealing plate is provided between adjacent side sealing plates, one side of the joint sealing plate is fixedly connected to one of the side sealing plates, and the other side is inserted into the mating gap between another side sealing plate and the roof panel.
[0027] By adopting the above technical solution, the gaps between the two ends of the roof panel and the main steel structure in the length direction are sealed by side sealing plates and joint sealing plates, thereby providing better sound insulation, noise reduction, waterproofing and heat preservation effects.
[0028] Optionally, the supporting net includes multiple warp threads and multiple weft threads, with adjacent warp threads located on the upper and lower sides of the same weft thread, and adjacent weft threads located on the upper and lower sides of the same warp thread; the threads of the supporting net pass through the bottom end of the connecting body, and the threads passing through the bottom end of all the connecting bodies are parallel to each other.
[0029] By adopting the above technical solution, the roof panels connected by the connector can only move within the width of a grid along the length of the thread. Attached Figure Description

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0041] It should be noted that in this article, relational terms such as “first” and “second” are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Example
[0042] This invention provides a prefabricated roof panel system, referring to... Figure 2 and Figure 3 The system includes multiple horizontal purlins 71 and multiple vertical purlins 72 fixed to the main steel structure 1. Two horizontal purlins 71 and two vertical purlins 72 in the same plane form a rectangle, constituting a frame. At least three roof panels 6 are installed on each frame. The roof panels 6 on each frame are of two types: edge panels 6a and middle panels 6b. Each set of roof panels 6 has two edge panels 6a and multiple middle panels 6b. The two edge panels 6a are located on both sides of the frame, and all the middle panels 6b are assembled between the two edge panels 6a. All roof panels 6 have a top plate 60. The difference between the edge panels 6a and the middle panels 6b is that one side of the top plate 60 of the edge panel 6a is a sealing edge 63, and the other side is an assembled structure, while both sides of the middle panel 6b are assembled structures.
[0043] Reference Figure 4 and Figure 5The assembly structure includes an assembly male end 62 and an assembly female end 61. The assembly structure on one side of the edge plate 6a is either an assembly female end 61 or an assembly male end 62. The assembly structure on one side of the middle plate 6b is an assembly female end 61, and the assembly structure on the other side is an assembly male end 62.
[0044] Reference Figure 5 The female assembly end 61 is composed of a first vertical plate 611 and a C-shaped plate 612. The first vertical plate 611 is perpendicular to the top plate 60, and its top end is integrated with the top plate 60, while its bottom end is integrated with the C-shaped plate 612. The male assembly end 62 is composed of a second vertical plate 621 and a J-shaped plate 622. The second vertical plate 621 is perpendicular to the top plate 60, and its top end is integrated with the top plate 60, while its bottom end is integrated with the J-shaped plate 622. The opening on the side of the C-shaped plate 612 faces the adjacent roof panel 6, and the J-shaped plate 622 is inserted laterally into the opening of the C-shaped plate 612 on the adjacent roof panel 6. The upper and lower surfaces of the J-shaped panel 622 fit seamlessly with the inner wall of the C-shaped panel 612. When the adjacent roof panels 6 are assembled, the J-shaped panel 622 is not inserted to the deepest position of the C-shaped panel 612 in the interlocking J-shaped panel 622 and C-shaped panel 612, but a gap is left for the roof panels 6 to be passively moved during future use.
[0045] Reference Figure 6 and Figure 7 The roof panel 6 also includes side sealing plates 64, which, along with the edge sealing 63, are located on adjacent sides of the roof panel 6. Each side sealing plate 64 has a protrusion 641, which is fixedly connected to the lower surface of the roof panel 60 by adhesive or nails. A joint patch 65 is provided between adjacent side sealing plates 64; one side of the joint patch 65 is fixedly connected to one side sealing plate 64, and the other side is inserted into the mating gap between the other side sealing plate 64 and the end of the roof panel.
[0046] Reference Figure 3 A row of collars 92 is fixed to the upper surface of both the transverse purlin 71 and the longitudinal purlin 72. All collars 92 in a row are equidistant and arranged along the length of the purlin. A winding post 91 is welded or glued to each collar 92.
[0047] Reference Figure 5 Multiple annular grooves 911 are spaced along the axial direction on the winding post 91, and the corresponding annular grooves 911 of all winding posts 91 on each purlin are located in the same plane. The annular grooves 911 are used to bind the wires, which can be steel wire or carbon fiber wire. The wires are divided into warp and weft, and the warp and weft are woven into the support net 8 in the same plane. The collar 92 and the winding post 91 constitute the support net tensioning structure 9, which connects all the wires around the edge of the support net 8. When all the wires are tightened by the winding post 91, the support net 8 is in a taut state.
[0048] During installation, first weave the silk threads into a net according to the principle that "adjacent warp threads are located on the upper and lower sides of the same weft thread, and adjacent weft threads are located on the upper and lower sides of the same warp thread." Then, tie knots at both ends of all the silk threads and loop them onto the winding posts 91 at two corresponding positions on the two purlins, ensuring that the knots at both ends of the silk threads are located in the annular grooves 911 at the same height on the two winding posts 91. Then, rotate the two winding posts 91 to tighten the silk threads. Finally, fix the winding posts 91 to the collar 92 by gluing or welding to maintain the tension of the silk threads.
[0049] Reference Figure 5 When this roof panel system is in use, the supporting net 8 is taut and has three layers of parallel supporting nets 8. The top surface of the bottom supporting net 8 is covered with a perforated steel plate 13 in a zigzag shape. A layer of dustproof and insect-proof non-woven fabric 14 is laid on top of the perforated steel plate 13. A sound-absorbing material layer 11 is laid on top of the non-woven fabric layer 14, and the upper surface of the sound-absorbing material layer 11 is exactly pressed down by the second supporting net 8. A sound-insulating material layer 12 is laid between the upper surface of the second supporting net 8 and the lower surface of the third supporting net 8. The edges of both the sound-insulating material layer 12 and the sound-absorbing material layer 11 abut against the four rows of winding posts 91 on the four purlins. The third supporting net 8 supports the roof panel 6, and the lower surface of the C-shaped panel 612 of the roof panel 6 is in contact with the third supporting net 8.
[0050] Reference Figure 8 and Figure 9 Multiple connectors 10 are fixed to the lower surface of the roof panel 60. Each connector 10 consists of an annular buckle 101 and an internally threaded cylinder 102. The wires of the supporting mesh 8 pass through the annular buckle 101. The bottom end of the internally threaded cylinder 102 is connected to the top of the annular buckle 101, and the top end is fixed to the lower surface of the roof panel 60. The annular buckle 101 is not a complete circle and has a notch. When the connector 10 is installed, the supporting mesh 8 is in a taut state, and the notch serves as the inlet 1011 for the wires of the supporting mesh 8. Threaded rods 1012, which are integrally connected to the annular buckle 101, are located on both sides of the inlet 101. The two threaded rods 1012 are threadedly engaged with the bottom end of the internally threaded cylinder 102. The wires passing through the annular buckles 101 of all connectors 10 are parallel to each other. Under the limiting effect of the wires, the roof panel 6 connected to the connector 10 can only move within the width of one grid along the length of the wires.
[0051] In summary, the prefabricated roof panel system provided in this embodiment, due to the blocking and limiting effect of the four edges of the sound-absorbing material layer 11 and the sound-insulating material layer 12 by the winding posts 91, will not move relative to the supporting net 8 and generate friction noise under strong winds. Furthermore, the multiple connectors 10 bind the roof panel 6 to the supporting net 8, and under strong winds, the movement range of the roof panel 6 is less than the width of one grid of the supporting net 8. Therefore, the friction noise between the roof panel 6 and the supporting net 8 is very small. With the action of the sound-absorbing material layer 11 and the sound-insulating material layer 12, and with the supporting net 8 constructed of smooth threads, this friction noise is almost negligible. In addition, since only the lower surface of the C-shaped panel 612 of the roof panel 6 contacts the top supporting net 8, the contact area is extremely small, and therefore the friction noise when the roof panel 6 moves relative to the supporting net 8 is also extremely small.
[0052] In this embodiment, the female assembly end 61 and the male assembly end 62 adopt a sliding plug-in fit, which can reduce the width dimension requirement of each roof panel 6 when assembling the roof panel 6; and after the assembly is completed, by sealing the assembly gaps of most of the roof panels 6 with glue, a few designated roof panels 6 can be moved under the action of strong wind, thereby avoiding the generation of large noise caused by a large number of roof panels 6 moving at the same time under the action of strong wind.
[0053] This roof panel system innovatively adopts a multi-layer support net 8 to achieve a stable arrangement of various functional modules (such as sound insulation, sound absorption, waterproofing, insect prevention, dust prevention, and heat insulation modules) under the roof panel 6, as well as a firm connection to the roof panel 6. At the same time, it has the excellent effect of almost no noise under high wind pressure and in seasons when metal products will expand and contract with temperature.
[0054] Because insulation modules can be installed between the multiple layers of support netting 8, the energy consumption for indoor heating and cooling in winter and summer can be reduced; because dustproof modules can be installed between the multiple layers of support netting 8, the frequency of using vacuum cleaners indoors can be reduced, thereby reducing energy consumption; because insectproof modules can be installed between the multiple layers of support netting 8, the amount of pesticides used can be reduced, thereby reducing pollutant emissions and protecting the environment.
[0055] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
