[0017] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.
[0018] Ancient wooden buildings mostly use traditional building materials and construction methods, resulting in poor thermal insulation performance and high energy consumption. Traditional insulation methods not only have limited insulation effects, but may also cause irreversible damage to ancient buildings, such as insecure installation, damage to the wooden structure, and lack of aesthetics, such as excessively thick protective layers and large overall thickness, making it difficult to meet modern protection and aesthetic needs.
[0019] In this embodiment, an energy-saving and thermal insulation protection system for ancient wooden structures is provided to protect the wooden columns of ancient buildings, such as... Figure 1 As shown, a new external envelope structure for ancient wooden pillars was constructed by combining traditional building materials such as polymer cement mortar, thin-walled steel wire mesh, and alkali-resistant fiberglass mesh. This structure enhances the thermal insulation performance of the ancient wooden structure, effectively prevents moisture erosion, protects the structure from dampness damage, and significantly reduces damage during renovation, preserving its original appearance and structural safety. More importantly, this external envelope structure blends seamlessly with the ancient building and its surrounding environment. It is lightweight, has good thermal conductivity, and is thinner, enhancing practicality while giving the ancient building new vitality and aesthetic appeal, successfully achieving the dual goals of protection and inheritance.
[0020] In this embodiment, an energy-saving and heat-insulating protection system for ancient wooden structures is provided for the protection of ancient wooden columns. The system includes: an ancient wooden column 1, a waterproof and breathable membrane 2, galvanized cement nails 3, a polymer cement mortar 4 with an embedded thin-walled steel wire mesh layer, a first vacuum insulation board 5, a polymer cement mortar bonding layer 6, a second vacuum insulation board 7, a thin plaster mortar with an embedded alkali-resistant fiberglass mesh 8, and a wood-look coating 9. The waterproof and breathable membrane 2 wraps around the ancient wooden column 1, the polymer cement mortar 4 with an embedded thin-walled steel wire mesh layer wraps around the waterproof and breathable membrane 2, and the galvanized cement nails 3 fix the polymer cement mortar 4 with the embedded thin-walled steel wire mesh layer to the waterproof and breathable membrane 2. On the ancient building's wooden pillar 1, a waterproof and breathable layer is formed to create a "pillar wrapping" structure; a first vacuum insulation board 5 is covered with a polymer cement mortar 4 with an embedded thin-walled steel wire mesh layer, a polymer cement mortar bonding layer 6 covers the first vacuum insulation board 5, and a second vacuum insulation board 7 is covered with a polymer cement mortar bonding layer 6. The first vacuum insulation board 5 and the second vacuum insulation board 7 are finely bonded using the polymer cement mortar bonding layer 6 to form a vacuum insulation layer with a double-layer insulation structure; a thin plaster mortar 8 with an embedded alkali-resistant fiberglass mesh is covered with the second vacuum insulation board 7, and a wood-look coating 9 is covered with the thin plaster mortar 8 with an embedded alkali-resistant fiberglass mesh to form a reinforcement layer.
[0021] In this embodiment, the ancient building wooden pillar is an ancient building wooden cylindrical structure, such as... Figure 2As shown, wrapping the wooden column 1 of the ancient building with a waterproof and breathable membrane 2 can effectively isolate the intrusion of external moisture, thereby preventing the wooden components from becoming moldy and condensing due to dampness, avoiding the decline in thermal insulation performance caused by moisture penetration. Moreover, through the special design of the waterproof and breathable membrane, it can also promote the smooth discharge of moisture accumulated inside the column, avoiding the decay problem caused by internal moisture retention. In addition, this wrapping method can also significantly reduce the chemical corrosion of the wooden components caused by cement mortar efflorescence, further extending the service life of the wooden components.
[0022] In this embodiment, the galvanized cement nails 3 are 1.8mm galvanized cement nails. The polymer cement mortar 4 with an embedded thin-walled steel wire mesh layer is firmly nailed to the 1 square meter ancient building wooden column 1 that has been wrapped with a waterproof and vapor barrier membrane 2 at intervals of 200mm. The nailing depth is 20mm. Then, polymer cement mortar is covered to form a waterproof and breathable layer of "column wrapping" structure. This waterproof and breathable layer ensures the structural strength while also meeting the requirements of safety and economy.
[0023] In this embodiment, both the first vacuum insulation panel 5 and the second vacuum insulation panel 7 are Class A arc-shaped 15mm vacuum insulation panels. High-polymer cement mortar 6 is used for fine bonding between the first vacuum insulation panel 5 and the second vacuum insulation panel 7, forming a double-layer vacuum insulation layer. Figure 3 As shown, to ensure a tight fit and seamless connection between the vacuum insulation panel and the base layer, a double-layer insulation structure is formed, which can improve the insulation effect and reduce the thermal bridging effect, thus reducing energy loss. In this embodiment, a polymer cement mortar 6 with an embedded thin-walled steel wire mesh layer is used as the base layer bonding material. This material not only provides good adhesion, but also enhances the overall structural strength through the embedded thin-walled steel wire mesh layer, enabling the ancient building wooden column 1 to withstand the challenges of various external environments.
[0024] In this embodiment, Class A curved vacuum insulation panels are selected, meaning that while providing the aforementioned multiple layers of protection, they also possess excellent fire resistance. Class A fire-resistant materials are virtually non-combustible, effectively resisting fire threats and providing another solid barrier for the safety of the ancient building's wooden components. This enhanced fire resistance not only strengthens the overall safety of the ancient building but also further consolidates the corrosion resistance of the wooden components, allowing the ancient building to maintain its original appearance and charm even after enduring the test of time.
[0025] In this embodiment, a thin layer of plaster mortar 8 with an embedded alkali-resistant fiberglass mesh is applied to the outside of the second vacuum insulation board 7 to ensure thermal insulation while improving the overall stability and durability of the wall. Finally, a wood-look coating 9 is applied to the outside of the thin plaster mortar 8 with the embedded alkali-resistant fiberglass mesh to form a reinforcement layer. Figure 4As shown, the thin plastering mortar 8 with embedded alkali-resistant fiberglass mesh and the wood-look coating 9 each have their own characteristics in building decoration. The former enhances the strength and durability of the wall, while the latter simulates the texture of wood to improve the aesthetics. The combined application of the two can give full play to their respective advantages, achieving a dual improvement in both durability and aesthetics, while reducing costs and increasing construction efficiency.
[0026] This embodiment involves ultra-low energy consumption modification of the existing wooden pillars of the ancient building, strengthening the original structure while also protecting it. A waterproof and breathable membrane is used to wrap the wooden pillars, reinforced with a thin-walled steel wire mesh embedded in polymer cement mortar and galvanized cement nails, forming a robust and reliable "pillar-wrapping" structure that provides strong support and protection for the wooden pillars. On this basis, two layers of curved vacuum insulation panels are bonded together, forming a highly efficient and durable double-layer vacuum insulation layer, effectively improving the thermal insulation performance of the ancient building. To further enhance the overall structural stability and durability, a thin layer of plaster mortar is applied over the second layer of insulation panels, with alkali-resistant fiberglass mesh embedded within. This design not only enhances the overall structural integrity but also provides a solid guarantee for the long-term use of the ancient building's wooden pillars. Using wood-look paint as the outermost layer not only enhances the overall decorative effect but also gives the wooden pillars excellent stain resistance, allowing the ancient building to retain its original rustic charm while radiating new vitality. Through this series of renovation measures, ultra-low energy consumption transformation of the ancient building's wooden pillars has been successfully achieved, giving them multiple functions such as heat preservation, insulation, waterproofing, and decoration, injecting new vitality and hope into the protection and inheritance of ancient buildings.
