Abstract
Description
Technical Field
[0001] This invention relates to the field of prefabricated building component technology, specifically a waterproof and soundproof integrated steel-wood modular roof panel. Background Technology
[0002] As the core protective structure at the top of a building, the roofing system occupies an indispensable position in the overall building structure. Roof panels, as the basic building blocks of the roofing system, must simultaneously meet multiple core performance requirements, including waterproofing, thermal insulation, sound insulation, and load-bearing capacity. With the rapid development of prefabricated buildings, higher standards have been set for the modularity, ease of assembly, and multi-functional integration capabilities of roof panels.
[0003] Currently, the roofing panels commonly used in building roofing projects mainly include the following categories: Metal roofing panels, represented by profiled steel sheets and aluminum-magnesium-manganese panels, have advantages such as lightweight, high strength, corrosion resistance, diverse shapes, and convenient installation, and are widely used in industrial buildings and large public buildings. However, metal materials have a high thermal conductivity, resulting in inherently insufficient thermal insulation performance. At the same time, metal panels are prone to generating significant impact noise in windy and rainy weather, leading to poor sound insulation and requiring additional sound insulation layers. Existing metal roofing systems mostly adopt a construction method of directly installing insulation cotton and metal panels on a steel structure, with only one insulation and waterproof layer, and both insulation and waterproof performance need to be improved.
[0004] Wooden roofing panels, represented by solid wood boards and plywood, have advantages such as being environmentally friendly and aesthetically pleasing, having excellent sound insulation properties, and a warm texture. However, wood itself has significant performance shortcomings: wood is prone to decay when exposed to water, and changes in moisture content can easily lead to defects such as cracking and warping, which alters the material's strength properties. In outdoor environments, in addition to dimensional changes, deformation, and light degradation, biological degradation is also a major cause of appearance damage, service life, and strength reduction. Wooden roofing panels have poor waterproof and moisture-proof performance, and are extremely susceptible to moisture, deformation, rot, and mold when exposed to humid environments for extended periods, resulting in severely insufficient durability and requiring frequent maintenance and repair.
[0005] Traditional composite roofing panels, while some existing technologies attempt to combine multiple materials to achieve various performance characteristics, mostly employ simple layered composite structures. These structures lack reasonable spatial zoning and collaborative design between functional layers, resulting in unclear functional division and unbalanced performance. On one hand, the functional layers compress and influence each other, making it difficult to fully utilize their optimal performance. On the other hand, a single composite structure struggles to simultaneously address multiple performance indicators such as waterproofing, thermal insulation, sound insulation, and load-bearing capacity, often resulting in compromises. Furthermore, existing roofing panels are mostly one-piece structures, making partial replacement impossible after internal structural damage, leading to high maintenance costs.
[0006] With the promotion of prefabricated buildings, some roof panel products have begun to develop towards modularization. However, the existing prefabricated roof structure is relatively simple overall, the connection between various splicing components is poor, and the overall stability and safety are not high. There are still problems in the installation and production of prefabricated components, making it difficult to guarantee the overall quality and construction safety.
[0007] In conclusion, there is an urgent need to develop an integrated roofing panel that can simultaneously achieve multiple properties such as waterproofing, thermal insulation, sound insulation, and load-bearing capacity, while also possessing good modular assembly performance. Summary of the Invention
[0008] To address the shortcomings of existing technologies, this invention proposes a waterproof and soundproof integrated steel-wood modular roof panel. Through a reasonable spatial layering and functional integration design, the roof panel simultaneously possesses excellent waterproof, heat insulation, sound insulation, and load-bearing performance, and also has good modular assembly performance.
[0009] The technical solution adopted by this invention to solve its technical problem is: A waterproof and soundproof integrated steel-wood modular roof panel includes a rectangular frame, a color steel mounting base plate, an outer waterproof steel plate, an internal bracket, a composite functional layer, and a bottom decorative panel. The color steel mounting base plate is sealed and closed at the opening at the top of the rectangular frame. The outer waterproof steel plate is fixed above the color steel mounting base plate. The internal bracket is placed on the inner side wall of the rectangular frame. The internal bracket is adapted to the color steel mounting base plate. Inside the rectangular frame, in the area above the internal bracket, an upper air insulation cavity and a lower functional installation cavity are arranged sequentially from top to bottom. The composite functional layer is embedded in the lower functional installation cavity. The bottom decorative panel is placed at the opening at the bottom of the rectangular frame and covers the composite functional layer. The composite functional layer consists of a waterproof membrane layer, a wooden load-bearing board layer, a thermal insulation and sound insulation cotton layer, and a bottom lining layer from top to bottom. The bottom lining layer is attached and fixed to the upper surface of the internal bracket.
[0010] Compared with the prior art, the beneficial effects of the present invention are: This invention utilizes a three-tiered waterproof defense system—an outer waterproof steel plate, a color steel mounting base, and a waterproof membrane layer—to effectively protect the wooden load-bearing panel from moisture erosion, completely solving the problems of traditional wooden roof panels being susceptible to moisture damage, deformation, rot, mold, and insufficient durability. Simultaneously, the enclosed air layer in the upper air insulation cavity, along with the thermal and sound insulation cotton layer and the wooden load-bearing panel layer, works synergistically to form a highly efficient thermal and sound insulation system, significantly reducing building energy consumption and effectively blocking external noise, thus compensating for the poor thermal and sound insulation performance of metal roof panels. Furthermore, the steel structure support system composed of the rectangular frame and internal brackets is integrated with the wooden load-bearing panel layer. Rigid connections enable coordinated load-bearing of steel and wood, significantly improving the overall load-bearing capacity and deformation resistance of the roof panels while maintaining lightweight construction, overcoming the shortcomings of insufficient strength of single wooden roof panels. The layered structure of the composite functional layers arranged sequentially from top to bottom ensures clear division of labor and non-interference among waterproofing, thermal insulation, sound insulation, and load-bearing functions. All components are prefabricated in a modular manner, making on-site assembly convenient and efficient, and allowing for partial replacement and maintenance later. This comprehensively improves the durability, reliability, and construction efficiency of the roofing system, ensuring long-term stable fulfillment of the core requirements for waterproofing, thermal insulation, sound insulation, and load-bearing capacity of building roofs.
[0011] As a preferred embodiment, a further technical solution of the present invention is: Preferably, the upper air insulation cavity is a closed cavity.
[0012] Preferably, the internal bracket is a crisscrossing light steel keel structure, and the internal bracket is welded and fixed to the inner wall of the rectangular frame.
[0013] Preferably, the outer waterproof steel plate is a profiled color steel plate, and the crest direction of the outer waterproof steel plate is consistent with the length direction of the rectangular frame.
[0014] Preferably, the waterproof membrane layer is an SBS modified bitumen waterproof membrane, and the waterproof membrane layer is fully bonded to the wood load-bearing board layer with adhesive.
[0015] Preferably, the wooden load-bearing board layer is made of solid wood, and the wooden load-bearing board layer is fixed to the rectangular frame with self-tapping screws.
[0016] Preferably, the thermal insulation and sound insulation layer is made of rock wool board.
[0017] Preferably, the bottom decorative panel is mounted on the internal bracket and rectangular frame using self-tapping screws. Attached Figure Description

[0024] The present invention will be further illustrated below with reference to specific embodiments. The purpose of this illustration is solely to provide a better understanding of the invention. Therefore, the examples given do not limit the scope of protection of the present invention.
[0025] like Figures 1 to 5 As shown, a waterproof and soundproof integrated steel-wood modular roof panel is composed of a rectangular frame 1, a color steel mounting base plate 2, an outer waterproof steel plate 3, an internal bracket 4, a composite functional panel 5, and a bottom decorative panel 6.
[0026] The color steel mounting base plate 2 is sealed and fitted to the top opening of the rectangular frame 1. During installation, it is tightly fitted to the top edge of the rectangular frame 1 with sealant to achieve a top seal and prevent rainwater from seeping in from the top gaps.
[0027] The outer waterproof steel plate 3 is fixed above the color steel mounting base plate 2. The outer waterproof steel plate 3 is a profiled color steel plate, and the crest direction of the outer waterproof steel plate 3 is consistent with the length direction of the rectangular frame 1. The surface of the outer waterproof steel plate 3 is treated with a waterproof coating, which can directly resist external wind and rain erosion, forming the first waterproof barrier of the roof. After the outer waterproof steel plate 3 is installed, rainwater can be quickly discharged along the crest direction to prevent water seepage on the roof. At the same time, the profiled structure can improve the rigidity of the outer waterproof steel plate 3, reduce the deformation range under external forces, and improve the overall structural stability of the roof.
[0028] The internal bracket 4 is a crisscrossing light steel keel structure. The internal bracket 4 is welded and fixed to the inner wall of the rectangular frame 1 to form a continuous and stable mesh support system. This structure greatly improves the overall rigidity of the rectangular frame 1 and effectively resists deformation and vibration under load. The internal bracket 4 cooperates with the color steel mounting base plate 2 to form an upper air insulation cavity and a lower functional mounting cavity arranged sequentially from top to bottom in the area inside the rectangular frame 1 and above the internal bracket 4.
[0029] After the roof is assembled, the upper air insulation cavity is a closed and sealed cavity. It utilizes the low thermal conductivity of air, and the still air inside can effectively block heat conduction, thus playing a preliminary role in heat insulation.
[0030] The lower functional installation cavity is fitted with a composite functional layer 5, which consists of a waterproof membrane layer 501, a wooden load-bearing board layer 502, a thermal insulation and sound insulation cotton layer 503, and a bottom lining layer 504 from top to bottom.
[0031] The waterproof membrane layer 501 is an SBS modified bitumen waterproof membrane. The waterproof membrane layer 501 and the wooden load-bearing board layer 502 are fully bonded together with adhesive to form a complete and continuous waterproof barrier, eliminating rainwater penetration paths and effectively protecting the wooden load-bearing board layer 502 from moisture erosion, preventing the wooden load-bearing board layer 502 from deformation, rot and mildew due to moisture. At the same time, the fully bonded structure can enhance the integrity between layers and improve the overall structural stability of the roof panel.
[0032] The wooden load-bearing board layer 502 is made of solid wood. The wooden load-bearing board layer 502 is fixed to the rectangular frame 1 with self-tapping screws. The solid wood board has good structural strength and sound insulation performance. During use, it can effectively bear vertical loads, ensure the overall load-bearing capacity of the roof panel, block air transmission of sound, improve the sound insulation effect, and the rigid connection with the rectangular frame 1 can enhance the integrity of the composite functional layer 5.
[0033] The thermal insulation and sound insulation cotton layer 503 is a rock wool board. The rock wool board is embedded between the wooden load-bearing board layer 502 and the bottom lining layer 504. During use, it effectively blocks heat conduction and airborne sound transmission by relying on its own porous structure, which significantly improves the thermal insulation and sound insulation effect of the roof panel.
[0034] The bottom lining layer 504 is attached and fixed to the upper surface of the internal bracket 4, and the bottom lining layer 504 supports and protects the thermal insulation and sound insulation cotton layer 503.
[0035] The bottom decorative panel 6 is installed on the internal bracket 4 and the rectangular frame 1 with self-tapping screws. After installation, it forms a closed protection for the composite functional layer 5, preventing external moisture, dust and debris from entering.
[0036] This invention utilizes a three-tiered waterproof defense system—an outer waterproof steel plate, a color steel mounting base, and a waterproof membrane layer—to effectively protect the wooden load-bearing panel from moisture erosion, completely solving the problems of traditional wooden roof panels being susceptible to moisture damage, deformation, rot, mold, and insufficient durability. Simultaneously, the enclosed air layer in the upper air insulation cavity, along with the thermal and sound insulation cotton layer and the wooden load-bearing panel layer, works synergistically to form a highly efficient thermal and sound insulation system, significantly reducing building energy consumption and effectively blocking external noise, thus compensating for the poor thermal and sound insulation performance of metal roof panels. Furthermore, the steel structure support system composed of the rectangular frame and internal brackets is integrated with the wooden load-bearing panel layer. Rigid connections enable coordinated load-bearing of steel and wood, significantly improving the overall load-bearing capacity and deformation resistance of the roof panels while maintaining lightweight construction, overcoming the shortcomings of insufficient strength of single wooden roof panels. The layered structure of the composite functional layers arranged sequentially from top to bottom ensures clear division of labor and non-interference among waterproofing, thermal insulation, sound insulation, and load-bearing functions. All components are prefabricated in a modular manner, making on-site assembly convenient and efficient, and allowing for partial replacement and maintenance later. This comprehensively improves the durability, reliability, and construction efficiency of the roofing system, ensuring long-term stable fulfillment of the core requirements for waterproofing, thermal insulation, sound insulation, and load-bearing capacity of building roofs.
