SEALING AND VENTILATION DEVICEREFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit under 35 U.S. C. § 119(e) of U.S. Provisional Patent Application No. 63 / 530,074 filed on August 1, 2023, which is incorporated herein by reference.FIELD OF THE INVENTION
[0002] The invention relates to the field of building construction materials, specifically focusing on a sealing device designed to ensure the integrity and functionality of joints between air pipes and concrete structures in vertical castings. Such devices play a crucial role in maintaining the structural integrity of buildings by protecting these joints from environmental damage and ensuring proper airflow within the structural elements.BACKGROUND OF THE INVENTION
[0003] The use of sealing devices in construction dates back to the early days of modern building techniques, where the integrity of joints between differing materials like metal pipes and concrete structures was crucial for ensuring overall structural durability and functionality. Initially, materials such as tar, wax, and later, various caulking compounds were used. However, these materials often lacked long-term resilience and adaptability to diverse environmental conditions. As buildings became taller and architectural designs more complex, the need for more sophisticated and reliable sealing solutions became evident.
[0004] Traditional sealing methods frequently encountered several significant issues. First, the fit of the seal was often imprecise due to the rigid materials used, which did not accommodate the slight variations in pipe and joint sizes found in actual construction environments. This misfit could lead to gaps or over-compression, both of which compromise the seal. Leaks were a common consequence, leading to water damage, corrosion, and mold growth within structural elements. Additionally, many older sealingsolutions were not designed to withstand long-term exposure to UV light and temperature fluctuations, resulting in material degradation, loss of elasticity, and eventual failure of the seal. These problems necessitated frequent inspections and costly maintenance or replacement work, adding to the lifecycle cost of building projects.
[0005] Another critical shortfall of conventional seals was their inability to manage airflow and prevent debris ingress effectively. In many cases, seals that were sufficiently airtight to prevent leaks also restricted necessary air circulation, leading to poor indoor air quality and potential violations of building health codes. Conversely, more porous sealing solutions, while better for air exchange, allowed dust, pests, and other debris to enter through the joints, clogging air systems, and compromising the clean environment required, particularly in specialized settings like hospitals or laboratories. There exists a need for a sealing device that solves these issues.
[0006] The novel sealing device represents a significant advancement in the technology of construction seals. It is designed specifically for the challenges at the intersections of air pipes and vertical concrete castings. By integrating a peripheral gap that precisely conforms to the outer dimensions of the air pipe, the device ensures a snug fit that eliminates the common issue of misfit. This design not only prevents debris ingress but also maintains optimal airflow, striking a crucial balance that previous solutions lacked. These enhancements and the strategic design improvements make the new sealing device a revolutionary step forward in construction technology, promising to set new standards in building integrity, safety, and efficiency.SUMMARY OF THE INVENTION

[0017] The present invention relates to a sealing device 100 for air pipes in vertical concrete castings (beam, column, etc.). Referring to FIGS. 1-10, the sealing device 100 includes a frame 120 having elongated slits that are sized to allow air to flow through but block the passage of debris into a pipe. The frame 120 is substantially circular and includes a top portion and a middle portion.
[0018] In some embodiments, the frame 120 is constructed from a sophisticated UV- resistant polymer composite, which includes a blend of high-performance plastics and UV stabilizers. This composite material is selected for its exceptional durability and resistance to environmental degradation, particularly ultraviolet light which can cause many materials to become brittle and lose strength over time. The material’s inherent flexibility andstrength ensure that it can withstand not only UV exposure but also significant temperature variations without deforming or cracking. The single-piece construction eliminates joints or seams that could potentially weaken the structural integrity of the device, enhancing its overall durability and reliability.
[0019] The frame 120 of the sealing device 100 may also be made of a high-grade plastic that is reinforced with special materials against UV radiation and is particularly resistant to the high temperature environments.
[0020] In some embodiments, the frame 120 of the sealing device 100 may be made of silicone-based materials. This may be ideal for use in high-thermal environments. Silicone- based materials are particularly valuable in environments subject to significant thermal fluctuations. This material is renowned for its ability to withstand both high and low temperatures without losing its elastic properties. In settings like industrial exhaust systems or outdoor installations where temperatures may vary widely and frequently, silicone ensures that the seal expands and contracts in sync with the pipe it encases. This adaptive flexibility prevents the formation of gaps or cracks that could compromise the seal’s integrity. Moreover, silicone is resistant to ozone and ultraviolet light, adding to its suitability for outdoor applications where exposure to sunlight is continuous.
[0021] In some embodiments, the frame 120 of the sealing device 100 may be made of high-density polyethylene, which is useful for protecting the sealing device from exposure to high mechanical stress. HDPE is chosen for its robustness and impact resistance, making it ideal for industrial settings or construction areas prone to mechanical stresses. Its high tensile strength ensures that it can absorb shocks and impacts without cracking or shattering, which is critical in environments with heavy machinery or high foot traffic. Additionally, HDPE's resistance to chemicals and moisture makes it suitable for use in chemical plants or areas where the seal might be exposed to corrosive substances. The material's durability under such harsh conditions helps in reducing maintenance costs and extending the lifespan of the seal.
[0022] In other embodiments, the frame 120 of the sealing device 100 may be made of composite materials. Advanced composite materials, which combine fibers or fillers with a polymer matrix, offer tailored properties that can address specific needs. For example, carbon fiber-reinforced polymers (CFRP) provide exceptional strength-to-weight ratiosand stiffness, desirable in high-performance applications where minimal deformation is critical. Glass fiber-reinforced polymers (GFRP) are used for their dimensional stability and thermal endurance, beneficial in environments that require a durable seal under constant thermal cycling. These composites can be engineered to provide enhanced properties such as fire resistance or electrical conductivity, broadening the range of applications for the sealing device.
[0023] Referring again to FIGS. 1-10, the sealing device 100 further includes a snug-fit slot 140. The snug-fit slot 140 is an outward extension from the middle portion of the frame 120 and is designed to accommodate an outer diameter of air pipes with high precision. The slot 140 is engineered with an internal geometry that slightly tapers towards the inside, creating a pressure seal against the pipe as it is inserted. A tight fit is crucial for maintaining the seal under dynamic loads, including those caused by building settlement, vibrations from heavy traffic, or mechanical systems within the structure. The design also includes a small degree of flexibility to accommodate pipe thermal expansion and contraction, thus maintaining a constant force on the pipe and ensuring the integrity of the seal over the lifetime of the building.
[0024] The snug-fit slot 140 further includes an external notch 160 for adhesive application of the sealing device 100 on the concrete casting. The point is to close a vertical expansion joint between the concrete and the pipe, which includes a peripheral gap into which the pipe enters. The external notch 160 thereby seals a seam between the concrete and the pipe. The external notch 160 is shaped to maximize the contact area between the sealing device 100 and a concrete surface. This notch 160 runs around the periphery of the device and is designed to be filled with an industrial-grade adhesive. The choice of adhesive can be tailored to specific environmental conditions and concrete types, allowing for a versatile and secure installation. The notch’s 160 design ensures a deep penetration of the adhesive, creating a capillary action that helps to lock the seal into place. This robust bonding is crucial for areas exposed to high moisture or chemical substances, as it prevents the ingress of such materials which could undermine the seal.
[0025] The integration of these technical features allows the sealing device 100 to perform reliably in a wide range of environmental conditions. By addressing the common failures associated with traditional sealing methods, such as cracking, adhesive failure, and loss ofelastic recovery, the new device offers a significantly improved solution. The use of UV- resistant polymers ensures that the device’s performance will not degrade even in sun- exposed applications, while the snug-fit slot 140 and adhesive notch 160 provide a dual mechanism to combat moisture ingress and mechanical dislodging.
[0026] The selection of material variants based on environmental conditions and functional requirements is fundamental to the sealing device's performance. Each material brings specific advantages that enhance the device’s effectiveness and reliability. By matching material properties with environmental challenges and operational demands, the device can provide a reliable, long-lasting seal that minimizes the need for maintenance and replacement. This tailored approach ensures that the sealing device 100 can perform optimally across a broad spectrum of applications, from residential plumbing to high-stress industrial settings, thereby safeguarding the integrity of the structures it is used in.
[0027] By leveraging the unique properties of each material variant, the sealing device 100 not only meets but exceeds the traditional performance standards of construction seals, offering customizable solutions that are both innovative and practical for modern construction challenges.
[0028] The dimensional versatility of the sealing device 100 is critical to its application in diverse construction environments. By offering multiple size variants, the device ensures compatibility with a broad spectrum of pipe diameters, which is essential for maintaining the adaptability and utility of the sealing solution in various contexts.
[0029] The scaling of the sealing device 100 across different pipe diameters is designed to preserve the functional integrity of its features. Each size variant is engineered to ensure that the critical aspects — such as the snug-fit slot 140 and the adhesive notch 160 — remain proportionally effective regardless of size. This scalability allows for the device to be customized for specific pipe diameters, ensuring a perfect fit and optimal sealing performance. The ability to customize the device per installation need is particularly advantageous in construction projects where standard sizes do not suffice or where pipes with non-standard diameters are employed.
[0030] By accommodating a wide range of pipe diameters, from the smaller pipes typically found in residential plumbing to the much larger conduits used in industrial and commercial infrastructure, the sealing device 100 becomes a versatile tool in theconstruction industry’s arsenal. This broad range of applications increases the product's marketability and utility, allowing it to serve not just a niche market but a substantial segment of the construction sector. For instance, in large-scale commercial projects like shopping centers or office complexes, where air handling systems involve extensive piping networks of varying diameters, having a sealing device 100 that can adapt to these variations is crucial for project efficiency and effectiveness.
[0031] The dimensional variants of the sealing device 100 also play a critical role in ensuring that it performs optimally across different environmental conditions and operational demands. In residential settings, the device might need to accommodate minor thermal expansions and contractions typical of household heating and cooling cycles. In contrast, industrial settings might require the device to withstand more significant mechanical stresses and extreme environmental conditions. Each size variant is therefore not only about fitting different diameters but also about tailoring the device’s performance characteristics to meet the specific demands of the environment in which it is used.
[0032] The availability of multiple dimensional variants of the sealing device 100 ensures that construction projects can proceed without delays associated with incompatible or inadequate sealing solutions. It allows engineers and architects to specify the most suitable version of the device based on exacting project requirements, enhancing overall construction quality. Moreover, by providing a precise fit for a wide range of pipe sizes, the sealing device 100 minimizes the risk of leaks, increases the longevity of the seal, and reduces maintenance and repair costs over the building's life span.
[0033] These expanded capabilities highlight the sealing device 100's role as a critical component in modern construction, where its ability to adapt to various scales and complexities of installations is as important as its primary function of sealing and protecting building infrastructure.
[0034] Here is a revised and expanded version of the disclosure, edited for clarity and accuracy, with additional details to emphasize the functionality and applicability of the sealing device 100.
[0035] Traditional adhesive, for example industrial glue, is utilized to secure the sealing device 100 to the pipe. In addition to the traditional adhesive notch, alternative embodiments of the sealing device 100 feature options for tool-free installation to enhanceusability and versatility in diverse construction environments. Mechanical fastening elements, such as snap-fit clips or magnetic strips, are integrated into the design specifically for scenarios where speed and the ability to reverse the installation are paramount. These features facilitate rapid deployment and straightforward removal without compromising the integrity of the seal. This adaptability proves invaluable during the building lifecycle, enabling easy adjustments and maintenance.
[0036] The snap-fit clips are designed with resilient, high-performance plastic that allows them to lock securely into place while providing enough flexibility to be disengaged without special tools or significant force. This design is particularly beneficial in temporary installations or in situations where frequent modifications to the piping or structural elements are anticipated. It also reduces the time and labor costs associated with traditional sealing methods that often require caulking or welding.
[0037] Magnetic strips, on the other hand, offer a unique advantage in metal-rich environments where they can be quickly attached to iron- containing surfaces without any physical alteration to the structural components. This feature is especially useful in modular construction settings, where it allows for prefabricated parts to be assembled with precision and efficiency. The magnets are selected for their strength and durability, ensuring that they provide a reliable seal even in the presence of vibration or thermal expansion and contraction.
[0038] Furthermore, the inclusion of these tool-free fastening options does not detract from the sealing device’s performance in harsh conditions. Both the snap-fit clips and magnetic strips are designed to maintain their functional integrity under a wide range of environmental stressors, including UV exposure, moisture, and temperature fluctuations. This robustness ensures that the sealing device 100 remains a reliable component of the construction, capable of adapting to both standard and demanding applications without the need for frequent replacements or repairs.
[0039] By integrating these advanced mechanical fastening technologies, the sealing device 100 not only meets the traditional needs of air-tight and secure seals but also addresses the modern construction industry's demands for flexibility, efficiency, and costeffectiveness. This expanded functionality highlights the device's role as a critical tool in the evolving landscape of building technology, where the ability to adapt quickly andeffectively to changing requirements is as essential as the foundational sealing purpose it serves.
[0040] The sealing device 100 may be manufactured using a sophisticated UV-resistant polymer composite that includes a blend of high-performance plastics and UV stabilizers. The manufacturing process begins with the selection of material variants based on the specific environmental conditions and operational demands they will face. These materials are processed and molded to form the main body of the sealing device 100, which includes a snug-fit slot 140 and an external notch 160 designed for adhesive application.
[0041] The snug-fit slot 140 is engineered with precision to accommodate the outer diameter of air pipes, featuring an internal geometry that slightly tapers towards the inside. This taper is critical as it creates a pressure seal against the pipe when inserted, ensuring a tight fit that maintains the seal under dynamic loads. The external notch 160 around the periphery of the device is strategically shaped to maximize the contact area between the device and a concrete surface, facilitating a deep penetration of adhesive for a robust bond.
[0042] Prior to installation, the air pipe must be prepared by cutting it to extend about 1.9 cm above the upper surface of the concrete casting. This precise measurement ensures that the sealing device 100 can be properly positioned and the snug-fit slot 140 effectively encases the pipe.
[0043] The next step involves applying an industrial-grade adhesive into the external notch of the sealing device 100. The choice of adhesive can be tailored to the specific types of concrete and environmental conditions at the installation site, enhancing the durability and effectiveness of the seal. These materials may include silicone, acrylic gum, etc. After filling the notch with adhesive, the sealing device 100 is dressed onto the air pipe. The adhesive should be allowed to cure as per the manufacturer's recommendations, securing the sealing device 100 firmly to both the pipe and the concrete structure.
[0044] In embodiments where speed and reversibility are paramount, alternative embodiments of the sealing device 100 include mechanical fastening elements like snap- fit clips or magnetic strips. These elements are integrated during the manufacturing process and allow for tool-free installation. Snap-fit clips provide a secure lock that can be easily engaged and disengaged, ideal for temporary installations or where frequent adjustmentsare required. Magnetic strips offer a rapid attachment method in metal-rich environments, allowing the sealing device 100 to be affixed without altering the structural components.
[0045] These tool-free options do not compromise the sealing integrity but instead offer enhanced flexibility for maintenance and adjustments throughout the building's lifecycle. Their inclusion in the design addresses the construction industry's need for efficient, adaptable solutions that can be quickly implemented in a variety of construction scenarios.
