Description

Technical Field

[0001] This invention relates to the field of roof construction technology, and in particular to a walkway system for a metal composite sandwich panel roof and a construction method for the walkway system. Background Technology

[0002] With the development of the construction industry, metal roofing is widely used in industrial plants, logistics warehouses, stadiums, and other buildings. To ensure the convenience of operation and maintenance after project implementation and to protect the roofing system, it is necessary to design walkways on the metal roof for regular use by maintenance or other personnel, i.e., walkway systems.

[0003] For the metal composite sandwich panel roofing that has emerged in recent years: the surface layer is a metal composite profiled sheet, the middle layer is an insulation layer, and the bottom layer is a profiled steel sheet. Currently, walkway panel systems typically use screws to fix them to the metal composite sandwich panel roof. However, these screws can penetrate directly into the metal composite sandwich panel roof, affecting the waterproofing, sealing, and reliability of the roof at the holes in the roof panel. Summary of the Invention

[0004] The main objective of this invention is to propose a walkway system for metal composite sandwich panel roofs and a construction method for the walkway system, aiming to solve the problem that existing walkway panel systems fixed with screws easily reduce the waterproof sealing and reliability of metal composite sandwich panel roofs.

[0005] To achieve the above objectives, the walkway system for metal composite sandwich panel roofs proposed in this invention includes: Multiple walkway panels are arranged sequentially end-to-end, extending along a first horizontal direction. The bottom of each walkway panel protrudes downwards to form multiple first mounting protrusions, and the top of each walkway panel protrudes upwards to form multiple second mounting protrusions. The multiple first mounting protrusions and multiple second mounting protrusions are staggered along a second horizontal direction, which is perpendicular to the first horizontal direction. The top of each walkway panel is recessed downwards corresponding to the position of each first mounting protrusion to form multiple first mounting grooves. The bottom wall of at least one first mounting groove is spaced apart along the extending direction of the walkway panel. The walkway is provided with multiple drainage holes. The bottom of each walkway panel is recessed upward to form multiple second mounting grooves corresponding to the positions of the second mounting protrusions. Each walkway panel has two connecting parts at both ends along its extension direction. In any two adjacent walkway panels, the first mounting protrusion of one walkway panel is engaged with the first mounting groove of the other walkway panel, and the second mounting protrusion of one walkway panel is engaged with the second mounting groove of the other walkway panel. The two adjacent connecting parts on the two walkway panels are connected to each other so that the two adjacent walkway panels overlap. A support assembly, the support assembly including support structures, a plurality of support structures are spaced apart at the bottom of each walkway panel along the first horizontal direction, the bottom of each support structure is welded to the roof, and the first mounting protrusion of each walkway panel is supported on the top of the plurality of support structures at its bottom and is detachably connected to the top of the plurality of support structures at its bottom.

[0006] In one embodiment, each of the connecting portions is provided with a connecting hole, which is disposed on the bottom wall of the first mounting groove and extends vertically through the bottom wall of the groove. In any two adjacent walkway plates, the connecting holes of two adjacent connecting portions on the two walkway plates are connected by bolts.

[0007] In one embodiment, each of the connecting portions has a plurality of connecting holes, which are distributed along the second horizontal direction on the bottom wall of different first mounting slots.

[0008] In one embodiment, the support structure includes a support base and a support beam, the support beam extending along the second horizontal direction, the bottom of the support base being welded to the roof, the bottom of the support beam being mounted on the top of the support base, the top of the support beam being used to support a plurality of first mounting protrusions of the corresponding walkway slab, and the top of the support beam being detachably connected to at least one of the first mounting protrusions it supports.

[0009] In one embodiment, the support beam has mounting holes that can be connected to the connecting holes or at least one drainage hole of the walkway slab it supports via bolts.

[0010] In one embodiment, the support beam is provided with a plurality of mounting holes spaced apart along the second horizontal direction.

[0011] In one embodiment, a polymer waterproof membrane is provided around the outer periphery of the support base, and the polymer waterproof membrane is attached to the roof.

[0012] In one embodiment, a plurality of support seats are provided at intervals along the second horizontal direction at the bottom of the support beam, and each support seat and the support beam it supports are detachably connected.

[0013] In one embodiment, the walkway slab is a zinc-aluminum-magnesium profiled steel sheet.

[0014] This invention also proposes a construction method for a walkway system, which is used to construct a walkway system for a metal composite sandwich panel roof, the construction method comprising: Install the plurality of the supporting structures on the roof at preset locations; Multiple walkway panels are installed on top of the multiple supporting structures; The adjacent connecting parts of two adjacent walkway panels are connected, and the first mounting groove and the second mounting protrusion of each walkway panel are respectively engaged with the second mounting protrusion and the second mounting groove of the other adjacent walkway panel to overlap the multiple walkway panels to form the walkway system.

[0015] The technical solution of this invention employs a first mounting protrusion at the bottom of the walkway panel and a second mounting protrusion at the top of the walkway panel, with the two rows of protrusions staggered along a second horizontal direction. Simultaneously, a first mounting groove is formed by a downward indentation at the top of the walkway panel corresponding to the position of the first mounting protrusion, and a second mounting groove is formed by an upward indentation at the bottom of the walkway panel corresponding to the position of the second mounting protrusion. Furthermore, at least one first mounting groove has drainage holes spaced apart on its bottom wall along the extension direction of the walkway panel. This allows adjacent walkway panels to overlap through the interlocking of the first mounting protrusion and the first mounting groove, and the second mounting protrusion and the second mounting groove, and is connected by a connecting part. The walkway panels are mutually fixed to form a continuous walkway. Furthermore, by arranging multiple support structures at intervals along the first horizontal direction, the bottom of each support structure is welded to the metal composite sandwich panel roof. The first mounting protrusion of the walkway panel rests on the top of the support structure and forms a detachable connection with it. This enables rapid installation and disassembly of the walkway system, eliminating the need for screws to penetrate the metal composite sandwich panel roof. This avoids the reduced waterproofing, sealing, and reliability issues associated with traditional screw-penetrating metal composite sandwich panel roofs, while simultaneously improving the load-bearing capacity and stability of the walkway system, extending its service life, and reducing maintenance costs. Additionally, the mounting holes on the bottom wall of the first mounting groove allow for rapid drainage of accumulated water from the walkway panel, preventing water accumulation from affecting pedestrian passage.

[0023] With the development of the construction industry, metal roofing is widely used in industrial plants, logistics warehouses, stadiums, and other buildings. To ensure the convenience of operation and maintenance after project implementation and to protect the roofing system, it is necessary to design walkways on the metal roof for regular use by maintenance or other personnel, i.e., walkway systems.

[0024] For the metal composite sandwich panel roofing that has emerged in recent years: the surface layer is a metal composite profiled sheet, the middle layer is an insulation layer, and the bottom layer is a profiled steel sheet. Currently, walkway panel systems typically use screws to fix them to the metal composite sandwich panel roof. However, these screws can penetrate directly into the metal composite sandwich panel roof, affecting the waterproofing, sealing, and reliability of the roof at the holes in the roof panel.

[0025] This invention proposes a walkway system 100 for a metal composite sandwich panel roof.

[0026] Please see Figures 1 to 4 In one embodiment of the present invention, the walkway system 100 of the metal composite sandwich panel roof includes a support assembly 20 and a plurality of walkway panels 10; wherein, the plurality of walkway panels 10 are arranged end to end, the walkway panels 10 extend along a first horizontal direction, the bottom of each walkway panel 10 protrudes downward to form a plurality of first mounting protrusions 11, the top of each walkway panel 10 protrudes upward to form a plurality of second mounting protrusions 12, the plurality of first mounting protrusions 11 and the plurality of second mounting protrusions 12 are staggered along a second horizontal direction, the first horizontal direction is perpendicular to the second horizontal direction, the top of each walkway panel 10 is recessed downward to form a plurality of first mounting grooves 13 corresponding to the positions of each first mounting protrusion 11, at least one first mounting groove 13 has a plurality of drainage holes 15 spaced apart along the extension direction of the walkway panel 10, and the bottom of each walkway panel 10 is recessed upward to form a plurality of first mounting grooves 13 corresponding to the positions of each second mounting protrusion 12. The system comprises multiple second mounting slots 14, and each walkway 10 has two connecting portions 16 at both ends along its extension direction. In any two adjacent walkway 10s, the first mounting protrusion 11 of one walkway 10 engages with the first mounting slot 13 of the other walkway 10, and the second mounting protrusion 12 of one walkway 10 engages with the second mounting slot 14 of the other walkway 10. The two adjacent connecting portions 16 on the two walkway 10s are connected to each other so that the two adjacent walkway 10s overlap. The support assembly 20 includes support structures 21. Multiple support structures 21 are spaced apart along the first horizontal direction at the bottom of each walkway 10. The bottom of each support structure 21 is welded to the roof. The first mounting protrusion 11 of each walkway 10 is supported on the top of the multiple support structures 21 at its bottom and is detachably connected to the top of the multiple support structures 21 at its bottom.

[0027] The first horizontal direction is Figure 1 The front-back direction, the second horizontal direction is Figure 2The left and right directions in the middle.

[0028] The technical solution of the present invention employs a first mounting protrusion 11 at the bottom of the walkway slab 10 and a second mounting protrusion 12 at the top of the walkway slab 10, with the two rows of protrusions staggered along a second horizontal direction. Simultaneously, a first mounting groove 13 is formed by a downward indentation at the top of the walkway slab 10 corresponding to the position of the first mounting protrusion 11, and a second mounting groove 14 is formed by an upward indentation at the bottom of the walkway slab 10 corresponding to the position of the second mounting protrusion 12. Furthermore, at least one first mounting groove 13 has drainage holes 15 spaced apart on its bottom wall along the extending direction of the walkway slab 10. This allows adjacent walkway slabs 10 to interlock through the mutual engagement of the first mounting protrusion 11 and the first mounting groove 13, and the second mounting protrusion 12 and the second mounting groove 14. The walkway 100 is connected and fixed together by the connecting part 16 to form a continuous walkway. Furthermore, by arranging multiple support structures 21 at intervals along the first horizontal direction, the bottom of the support structures 21 is welded to the metal composite sandwich panel roof, and the first mounting protrusion 11 of the walkway panel 10 is supported on the top of the support structures 21 and forms a detachable connection with the top of the support structures 21. This achieves rapid installation and disassembly of the walkway system 100 without the need for screws to penetrate the metal composite sandwich panel roof, avoiding the problems of reduced waterproofing, sealing, and reliability caused by traditional screw penetration of the metal composite sandwich panel roof. It also improves the load-bearing capacity and stability of the walkway system 100, extends its service life, and reduces maintenance costs. Moreover, the mounting holes on the bottom wall of the first mounting groove 13 allow for rapid drainage of accumulated water from the walkway panel 10, preventing water accumulation from affecting pedestrian passage.

[0029] In one embodiment of the present invention, each connecting part 16 is provided with a connecting hole 161. The connecting hole 161 is disposed on the bottom wall of the first mounting groove 13 and penetrates the bottom wall of the groove vertically. In any two adjacent walkway plates 10, the connecting holes 161 of two adjacent connecting parts 16 on the two walkway plates 10 are connected by bolts.

[0030] Specifically, a connecting hole 161 is provided in the connecting part 16, and the connecting hole 161 is set in the bottom wall of the first mounting groove 13 and penetrates the bottom wall of the groove vertically. When two adjacent walkway panels 10 overlap, the connecting holes 161 of the adjacent connecting parts 16 can be vertically connected by bolts. The connection is simple and convenient, which further enhances the connection strength and stability between adjacent walkway panels 10, ensures that the walkway system 100 will not loosen or shift during use, and improves the safety and reliability of the overall structure.

[0031] In one embodiment of the present invention, each connecting part 16 is provided with a plurality of connecting holes 161, and the plurality of connecting holes 161 are distributed along the second horizontal direction on the bottom wall of different first mounting grooves 13.

[0032] Furthermore, by opening multiple connection holes 161 in each connection part 16 and distributing the multiple connection holes 161 along the second horizontal direction on the bottom wall of different first mounting grooves 13, adjacent walkway panels 10 can be connected simultaneously at different positions by multiple bolts when overlapping, thereby further improving the connection strength and stability between adjacent walkway panels 10, ensuring that the walkway system 100 can withstand greater loads and impacts during use. At the same time, since the connection holes 161 are distributed in different first mounting grooves 13, the force is more even after the bolts are connected, effectively avoiding the connection failure problem caused by excessive force at a single point, and further improving the overall safety and reliability of the walkway system 100.

[0033] In one embodiment of the present invention, the support structure 21 includes a support base 211 and a support beam 212. The support beam 212 extends along a second horizontal direction. The bottom of the support base is welded to the roof. The bottom of the support beam 212 is installed on the top of the support base 211. The top of the support beam 212 is used to support a plurality of first mounting protrusions 11 of the corresponding walkway slab 10. The top of the support beam 212 is detachably connected to at least one of the first mounting protrusions 11 it supports.

[0034] Specifically, the bottom of the support base 211 is welded to the metal composite sandwich panel roof, and the support beam 212 extends along the second horizontal direction and is fixed to the top of the support base 211. The top of the support beam 212 simultaneously supports multiple first mounting protrusions 11 of the same walkway panel 10 and forms a detachable connection with at least one of the first mounting protrusions 11. This integrates the originally dispersed multiple stress points into a continuous support beam 212, so that the load of the walkway panel 10 is evenly distributed along the second horizontal direction. The detachable connection between the support beam 212 and the individual first mounting protrusion 11 retains the function of quick assembly and disassembly, reduces the number of connecting parts, simplifies on-site operation, and improves assembly efficiency. The continuous support beam 212 significantly reduces the arrangement density of the support structure 21 along the first horizontal direction, reduces the heat-affected zone of the roof welding, and further ensures the waterproof sealing and long-term reliability of the metal composite sandwich panel roof.

[0035] In one embodiment of the present invention, the support beam 212 is provided with mounting holes, which can be connected to the connecting holes 161 of the walkway 10 it supports or at least one drainage hole 15 by bolts.

[0036] Furthermore, mounting holes are made on the support beam 212, and these mounting holes can be detachably connected to the connection holes 161 or at least one drainage hole 15 of the walkway 10 via bolts. This allows for quick fixing of the support beam 212 to the walkway 10 using the existing drainage holes 15 or connection holes 161 of the walkway 10, without the need for additional holes or accessories. This simplifies the installation process, improves construction efficiency, enables multi-functional application of the existing holes on the walkway 10, optimizes the structural layout, and reduces manufacturing costs.

[0037] In one embodiment of the present invention, the support beam 212 is provided with a plurality of mounting holes spaced apart along its second horizontal direction.

[0038] Furthermore, multiple mounting holes are spaced apart in the extension direction of the support beam 212, so that the support beam 212 can form multi-point bolt connections with the connection holes 161 or drainage holes 15 at different positions on the walkway 10, thereby achieving a more uniform and stable fixation between the walkway 10 and the support beam 212.

[0039] In one embodiment of the present invention, a polymer waterproof membrane 213 is provided around the outer periphery of the support base 211, and the polymer waterproof membrane 213 is attached to the roof.

[0040] Specifically, a polymer waterproof membrane 213 is pre-laid around the weld area between the support 211 and the metal composite sandwich panel roof. This polymer waterproof membrane 213 is made of TPO or PVC material, which can provide an additional layer of polymer membrane coverage for the installation location of the support 211, thereby more effectively blocking rainwater infiltration and ensuring waterproof reliability.

[0041] In one embodiment of the present invention, a plurality of support seats 211 are provided at intervals along the second horizontal direction at the bottom of the support beam 212, and each support seat 211 is detachably connected to the support beam 212 it supports.

[0042] Specifically, by using multiple support seats 211, the load acting on the support beam 212 can be evenly distributed, which can avoid the support beam 212 being subjected to single-point force and effectively improve the structural reliability of the support structure formed by the combination of support beam 212 and support seats 211.

[0043] In one embodiment of the present invention, the walkway slab 10 is a zinc-aluminum-magnesium profiled steel sheet. Zinc-aluminum-magnesium profiled steel sheets are characterized by high hardness and wear resistance, allowing the walkway slab 10 to withstand frequent walking by maintenance personnel and tool dragging, while preventing scratches and corrosion on the surface, thus maintaining the integrity of the walkway's function and its clean appearance.

[0044] The present invention also proposes a construction method for a walkway system 100, which is used to construct a walkway system 100 forming a metal composite sandwich panel roof. The construction method includes: Step S100: Install the plurality of support structures on the roof at preset locations; Step S200: Install multiple walkway panels on top of the multiple support structures; In step S300, the adjacent connecting portions of two adjacent walkway panels are connected, and the first mounting groove and the second mounting protrusion of each walkway panel are respectively engaged with the second mounting protrusion and the second mounting groove of the other adjacent walkway panel to overlap the multiple walkway panels to form the walkway system. The specific structure of the walkway system 100 of the metal composite sandwich panel roof refers to the above embodiment. Since the construction method of this walkway system 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, and will not be described in detail here.

[0045] Specifically, when overlapping two walkway panels 10, the first mounting protrusion 11 of one walkway panel 10 is engaged with the first mounting groove 13 of the other walkway panel 10, and the second mounting protrusion 12 of the other walkway panel 10 is engaged with the second mounting groove 14 of the walkway panel 10. Then, the two connecting parts 16 on the two walkway panels 10 that are close to each other are connected to complete the overlap of the two walkway panels 10.

[0046] The above description is merely an exemplary embodiment of the present invention and does not limit the scope of the present invention. Any equivalent structural transformations made based on the technical concept of the present invention and the contents of the specification and drawings of the present invention, or direct / indirect applications in other related technical fields, are included within the protection scope of the present invention.
