Description

Technical Field

[0001] The present invention belongs to the technical field of roof deformation joint cover plates, and in particular, relates to an integrated roof deformation joint cover plate. Background Art

[0002] Deformation joint is an important concept in construction engineering. It refers to the fact that buildings may deform, crack or even break under the influence of external factors such as temperature, humidity, earthquake and other natural conditions. In order to prevent this from happening, architects will reserve some gaps in the design, which are called deformation joints. There are types of deformation joints, including expansion joints, settlement joints and seismic joints. Their purpose is to prevent building deformation, and they can be collectively referred to as deformation joints.

[0003] It is a common practice to add a cover plate on the roof expansion joint. Such a cover plate is usually called a roof expansion joint cover plate. The function of this cover plate is to protect the expansion joint and prevent rainwater, debris, etc. from entering the expansion joint. It also plays a certain decorative role. The design and installation of the cover plate need to take into account the width, length and environment of the expansion joint to ensure that it can adapt to the changes of the expansion joint and meet the requirements of waterproofing and fire prevention.

[0004] Regarding the safety and convenience of construction workers passing through the roof expansion joints, traditional roof expansion joint covers may only cover the roof expansion joints and cannot provide sufficient safety and convenience. After the construction is completed, personnel often need to set up walking steps on both sides of the expansion joints, which not only causes significant damage to the roof finishing layer, but also affects the overall appearance of the roof, which is not conducive to project excellence and observation.

[0058] The present invention provides a second embodiment of an integrated roof expansion joint cover plate. In this embodiment, some design details are changed to adapt to different application scenarios or improve performance.

[0059] The frame structure can effectively disperse the load applied to the cover plate through the support points evenly distributed on the four sides. This design reduces local stress concentration, thereby reducing the risk of structural deformation and damage. Due to the design of the frame, the cover plate body can withstand greater weight and external impact. This allows it to maintain good stability during construction even when heavy equipment or materials pass by, ensuring the safety of construction workers. The flexibility of the frame structure enables it to adapt to roof deformation joints of different sizes and shapes. The size and shape of the frame can be adjusted according to specific building needs to meet different engineering requirements. The prefabricated components of the frame can be manufactured in the factory and only need to be assembled on site, reducing construction time and labor costs. The modular design of the frame structure makes it easy to disassemble and replace a part when maintenance or replacement is required without dismantling the whole. Reduces the complexity and cost of later maintenance. The top design of the frame structure can better combine with the waterproof layer to reduce the risk of rainwater leakage. Through reasonable drainage design, ensure that the water flow can be discharged smoothly to avoid water accumulation.

[0060] The tread 20 is designed to be adjustable, and the length of the tread can be flexibly adjusted according to the specific width of the roof deformation joint to adapt to deformation joints of different sizes. This design not only improves the convenience of construction, but also ensures the safety and stability of the tread. The tread uses a material with good anti-slip performance, such as a stainless steel plate with an anti-slip texture. 304 stainless steel plate is widely used in various construction sites, such as hospitals, schools and factories, due to its excellent corrosion resistance and wear resistance. This material can effectively resist the erosion of chemical substances such as acids and alkalis and maintain a long service life. In addition, the surface treatment of the tread can also adopt anti-slip patterns and other methods to increase the friction of the steps and improve the safety of use. This anti-slip design is particularly suitable for wet or slippery environments to ensure the safety of construction workers when passing. Through this adjustable tread design, construction workers can flexibly pass between different roof deformation joints, avoiding the trouble of setting up temporary steps in traditional methods, while reducing damage to the roof finishing layer, improving the overall aesthetics and the project's excellent viewing effect.

[0061] The sealing layer 30 adopts a double-layer sealing design, which not only provides a better sealing effect, but also significantly improves weather resistance, making it adaptable to various harsh environmental conditions. The inner layer is made of soft rubber material, which has good elasticity and compressibility, and can fit tightly to the irregular surface of the roof anti-ridge to ensure the reliability of the seal. The outer layer is made of wear-resistant silicone material, which has excellent weather resistance and can resist the influence of ultraviolet rays, ozone, rain and temperature changes, thereby extending the service life of the sealing layer. The rubber material of the inner layer provides excellent air tightness and water tightness, while the silicone material of the outer layer provides strong weather protection. This combination ensures the stability and durability of the sealing layer in the face of extreme weather conditions. The double-layer sealing design can effectively prevent the penetration of moisture and gas by forming a sealed space between the inner layer and the outer layer. This design also allows the outer layer to provide additional protection when the inner layer is worn or aged, ensuring that the overall sealing performance is not affected. Due to the weather resistance of the outer silicone material, the sealing layer 30 can withstand long-term sunlight exposure, temperature changes and rain erosion, thereby reducing the frequency of maintenance and replacement and reducing long-term operating costs. This double-layer sealing design enables the sealing layer 30 to maintain stable performance under various environmental conditions, whether it is high temperature, low temperature, dry or humid environment, it can provide a long-lasting sealing effect. The design of the double-layer sealing structure also takes into account the convenience of installation and maintenance. The softness of the inner rubber material makes installation easier, while the wear resistance of the outer silicone material simplifies maintenance work because they can resist wear caused by environmental factors. In summary, the double-layer sealing design of the sealing layer 30 provides an efficient, durable and adaptable sealing solution for various environmental conditions, providing a strong guarantee for the long-term stability and reliability of the roof expansion joint cover.

[0062] The integrated drainage system eliminates the problem of connecting multiple components in traditional drainage systems, reducing installation time and potential leakage risks. This design simplifies the construction process, reduces maintenance costs, and improves the overall efficiency of the system. The direct connection of the drainage piece 40 to the roof drainage pipe ensures that rainwater can be discharged from the cover system to the roof drainage system without obstruction. This direct connection method reduces the residence time of rainwater in the cover system, thereby reducing structural loads and potential corrosion problems caused by water accumulation. When designing the drainage piece 40, it is necessary to consider the design recurrence period and flow requirements of the roof drainage system. Calculations are made based on the maximum drainage capacity of the rainwater suspension pipe and the horizontal pipe to ensure that the system can operate effectively at the design flow rate. The material selection of the drainage piece 40 considers weather resistance, chemical resistance and wear resistance. The drainage pipe material selects appropriate materials according to temperature and pressure requirements, such as pressure-resistant plastic pipes, metal pipes or steel-plastic composite pipes. The design of the integrated drainage system is easy to maintain and clean. Regularly check whether the drainage piece 40 is blocked or damaged, and clean or replace it as necessary to ensure that the drainage system is unobstructed. When designing the drain 40, overflow protection measures are also considered to prevent the roof drainage system from exceeding its design capacity under extreme weather conditions. This can be achieved by setting up an overflow port or overflow pipe system to ensure that excess rainwater can be safely discharged during heavy rain. The design of the drain 40 also takes into account environmental factors such as temperature changes, ultraviolet radiation and chemical corrosion. The selected materials and designs can adapt to these environmental factors to ensure long-term stable operation of the system.

[0063] Through the above design, the drainage member 40 not only improves the functionality and safety of the roof expansion joint cover plate, but also helps to improve the aesthetics and practicality of the entire roof system.

[0064] The design of the fixing 50 adopts the concept of quick installation. Through the preset card slot and locking mechanism, the efficiency of fixing the cover plate body 10 and the step plate 20 on the roof countersill can be significantly improved. The quick installation design allows installation without traditional tools, for example, using quick locking components instead of bolts, which can save installation time and reduce the complexity of operation. This locking mechanism provides a constant clamping force to ensure the consistency and reliability of installation. The quick installation design is particularly suitable for occasions where frequent installation and disassembly are required, thereby improving the overall installation and disassembly efficiency. This design reduces the time and labor required for installation and disassembly, especially in occasions where construction or maintenance work needs to be completed quickly. The design of the quick installation fixing is simple and intuitive, allowing operators to quickly master installation skills. The simplicity of this design reduces the reliance on professional skills, thereby reducing the risk of errors and accidents during installation. The quick installation fixing can be designed to adapt to different roofing materials and structures, providing a flexible solution. Whether it is a roof made of metal, concrete or other materials, it can be quickly installed with this fixing. When the cover plate body or the step plate needs to be maintained or replaced, the quick-install fixtures can be easily removed, thereby reducing the time and difficulty of maintenance work. Since the quick-install fixtures reduce the operating time required on the roof, this helps reduce the risk of construction workers working at heights and improves overall construction safety. The design of the quick-install fixtures takes into account various environmental conditions, such as temperature changes, humidity, and ultraviolet radiation, ensuring reliability and durability under different climatic conditions. Through the above design, the fixture 50 not only improves the installation efficiency, but also enhances the safety, reliability and ease of maintenance of the roof expansion joint cover system.

[0065] The design of the telescopic layer 113 adopts a structure in which multiple layers of rubber and steel plates are alternately stacked, which not only provides superior telescopic performance but also significantly enhances durability. The telescopic layer 113 is composed of multiple layers of rubber and steel plates alternately stacked to form a composite structure that can effectively absorb and disperse the thermal expansion and contraction stress caused by temperature changes, thereby protecting the main structure from damage. The design of the multi-layer structure can adapt to larger building displacements, including displacements caused by temperature changes, foundation settlement, seismic activities, etc. The telescopic layer 113 can maintain good performance and stability under various environmental conditions. The rubber material has good elasticity and anti-aging properties, while the steel plate provides the necessary strength and rigidity. This combination allows the telescopic layer 113 to maintain stable performance even when subjected to dynamic loads for a long time, extending the maintenance cycle and service life. When designing the telescopic layer 113, by adjusting the number and thickness of the rubber layer and steel plate, its telescopic performance and load-bearing capacity can be optimized to adapt to different engineering requirements and environmental conditions. The telescopic layer 113 makes it more convenient to carry out maintenance or replacement when it is needed. If a layer of the structure is damaged, it can be replaced separately without replacing the entire expansion layer, thereby reducing maintenance costs and workload. In some designs, the expansion layer may be combined with high-damping vibration-reducing rubber bearings to reduce the noise and vibration generated by vehicles passing through the expansion joint, thereby improving the overall performance and driving comfort of the bridge. In summary, the multi-layer rubber and steel plate alternating stacking structure of the expansion layer 113 provides a high-performance, high-durability solution suitable for building expansion joint applications that need to frequently withstand dynamic loads and environmental changes.

[0066] The surface of the friction pad is designed with a honeycomb structure, which not only increases the friction coefficient and provides better cushioning performance, but also reduces the pressure on the roof structure. The honeycomb structure increases the friction coefficient between the friction pad and the contact surface by increasing the texture of the contact surface. The friction is improved by increasing the contact points and friction area, so that it is more firmly fixed on the roof structure and prevents sliding caused by wind load or thermal expansion. The honeycomb structure can effectively absorb the pressure generated by temperature changes or mechanical vibrations. It can disperse and absorb pressure and provide excellent cushioning performance. Due to the cushioning properties of the honeycomb structure, the friction pad is able to reduce the pressure directly acting on the roof structure, thereby protecting the roofing material and extending its service life. Honeycomb structures are widely used in various fields, including aerospace, due to their high strength and lightweight characteristics. In the friction pad design, the honeycomb structure provides optimized mechanical properties, which allows the material to reduce its own weight while maintaining strength, thereby reducing the pressure on the roof structure. Honeycomb structure friction pads are also widely used in the automotive industry, where they provide additional grip and wear resistance. The honeycomb structure of the friction pad is able to adapt to various environmental conditions, such as temperature changes, humidity and UV exposure, maintaining its performance. Due to the openness of the honeycomb structure, the friction pad is easier to inspect and maintain. Any damage or wear can be quickly identified and replaced, ensuring the integrity and functionality of the roof system. In summary, the honeycomb structure design of the friction pad provides an efficient, durable and adaptable solution for various environmental conditions, suitable for roof structures that need to withstand frequent dynamic loads and environmental changes.

[0067] The bottom of the tread 20 is designed with a lighting system to meet the work needs of construction workers at night or in low-light environments, greatly increasing the safety of construction. The lighting system can use motion sensing technology. When the construction workers approach the tread, the lighting automatically turns on and automatically turns off when the people leave. This not only saves energy but also ensures the safety of the construction workers. This sensing distance is adjustable and has a wide sensing range. It can intelligently identify the brightness of the environment to ensure that it is not mistakenly bright during the day and provide sufficient lighting at night. Embedding an LED light strip at the bottom of the tread can provide continuous and uniform lighting. This design is not only beautiful but also practical. The LED light strip can provide enough light to ensure that the construction workers can clearly see each step at night or in low-light environments, reducing the risk of falling or slipping. Since the construction environment may be exposed to various weather conditions, the design of the lighting system must have good waterproof and weather resistance. The selected lamps and electrical components can resist rain, dust and corrosion to ensure long-term stable operation. In order to ensure the safety of construction workers, the lighting system uses a low voltage power supply, such as a 12V or 24V transformer to reduce the risk of electric shock. The lighting system can be designed to automatically switch to emergency mode when the main power supply is cut off, ensuring that the lighting will not be interrupted in an emergency, thereby ensuring the safe evacuation of construction workers. The lighting system is easy and quick to install, does not require complicated wiring, and can be fixed to the bottom of the tread by embedded parts or adhesives. At the same time, the design of the lamps is easy to maintain and replace to ensure the long-term effectiveness of the lighting system. The lighting system uses high-efficiency and energy-saving LED lamps to reduce energy consumption and construction costs, while also complying with the concept of green and environmentally friendly architecture. Through the above design, the lighting system of the tread 20 not only improves the safety of night construction, but also increases construction efficiency and reduces the cost of long-term operation and maintenance.

[0068] Specifically, the principle of the present invention is that the integrated roof deformation joint cover plate provided by the present invention can be flexibly adjusted in size to meet the roof deformation joint requirements of different buildings through factory-customized production. The cover plate is fixed to the anti-sills on both sides of the deformation joint using expansion bolts. This installation method is not only easy to operate, but also can ensure the stability and safety of the cover plate.

[0069] The design of the cover plate takes into account the safe passage of construction workers. The setting of the step plate 20 provides a stable and safe passage for construction workers. The step plate has a stepped structure design with an inclination angle of 10-15°, which effectively prevents water accumulation. At the same time, the convex structure connection between the steps reduces the residence time of water on the step plate, thereby avoiding the influence of solar refraction on the cover plate.

[0070] In addition, the top of the top plate 111 of the integrated roof expansion joint cover is designed to be inclined from the center position to both sides, and the inclination angle is also between 10-15 degrees, which helps to prevent rainwater accumulation and enhances the drainage performance of the roof.

[0071] In terms of protecting the roofing finishing layer, the cover plate body 10 and the tread plate 20 of the present invention are provided with a sealing layer 30 at the edge where they contact the roofing, and the sealing layer 30 not only plays a waterproof role, but also protects the roofing facing bricks from damage. The design of the fixings also takes into account the protection of the roofing bricks, and the tread plate 20 is fixed to the roofing through the bottom plate fixings 52, which reduces direct contact and damage to the roofing bricks.

[0072] In summary, the integrated roof deformation joint cover plate of the present invention not only provides a convenient and safe roof deformation joint channel, but also avoids damage to the roof finishing layer.
