Description

Technical Field

[0001] The utility model relates to the technical field of energy-saving roof structures, in particular to a heat-insulating and heat-insulating antique building energy-saving roof structure. Background Art

[0002] With the intensification of the global energy crisis and growing environmental awareness, the construction industry is increasingly demanding energy conservation and emission reduction. Especially with the advancement of national energy conservation policies, building energy-saving technology has become a key element in architectural design. Among the many aspects of building energy conservation, roof thermal insulation is particularly important, as the roof is one of the main parts of a building exposed to the external environment, directly bearing the effects of solar radiation, wind and rain, and temperature fluctuations. If the roof structure's thermal insulation is insufficient, heat will easily escape in winter and indoor temperatures will easily rise in summer, resulting in significant energy consumption for heating and cooling. Therefore, optimizing the roof's thermal insulation and reducing energy consumption have become core tasks in modern architectural design.

[0003] In modern architecture, the application of energy-saving technologies is relatively mature. Through multi-layered roof structures, ventilation systems, and the rational use of insulation materials, the thermal insulation of buildings has been greatly improved. However, for period buildings, energy-saving design is much more challenging. Period buildings must not only inherit the cultural and aesthetic characteristics of traditional architecture but also adapt to modern functional requirements, which makes the application of energy-saving technologies even more challenging. Traditional period buildings often use tiles as roofing materials. While these tiles are highly aesthetic and have historical significance, they have significant shortcomings in thermal insulation and waterproofing. Traditional tiled roofs cause indoor heat to dissipate rapidly in cold winters, increasing heating energy consumption. In hot summers, the roof's insufficient insulation leads to excessively high indoor temperatures, requiring extensive use of air conditioning for cooling, which in turn increases energy consumption.

[0006] Preferably, the waterproof layer is a waterproof membrane, which is fixedly connected to the bottom surface of the tile layer by hot-melt. The hot-melt method provides a more secure connection between the waterproof layer and the tile layer, ensuring a long-lasting and stable waterproof effect, effectively preventing rainwater penetration, and extending the service life of the roof. Furthermore, the waterproof membrane has good flexibility and weather resistance, can adapt to different climate conditions, and enhance the overall durability of the roof.

[0008] Preferably, dust screens are fixedly mounted on the surfaces of the air inlet and outlet, and are made of stainless steel. These screens effectively prevent dust and debris from entering the ventilation layer, ensuring smooth operation of the ventilation system and preventing clogging of the vents. Stainless steel is corrosion-resistant and will not easily rust or age over long-term use, ensuring the durability and ease of maintenance of the ventilation system.

The surfaces of the air inlet 312 and the air outlet 322 are fixedly installed with a dustproof net 6, and the dustproof net 6 is made of stainless steel. The stainless steel dustproof net 6 can effectively prevent dust and debris from entering the ventilation layer 3, ensuring the smooth operation of the ventilation system and avoiding the problem of clogging of the air outlet 311. The stainless steel material has good corrosion resistance and will not easily rust or age in long-term use, ensuring the durability of the ventilation system and the convenience of maintenance. The air inlet 312 is located below the eaves 11, and the air outlet 322 is located at the ridge of the roof structure, which optimizes the natural ventilation effect of the roof and utilizes the principle of air convection to effectively remove hot air and moisture inside the roof structure, thereby improving thermal insulation performance.

[0023] Working principle: Tile layer 1 is located at the outermost layer of the roof structure, and is made of traditional antique tile materials. It is mainly used to maintain the beautiful appearance of antique buildings and continue the historical and cultural characteristics of traditional buildings. In addition, tile layer 1 also has an important protective function and can effectively block the invasion of external environmental factors such as rainwater and wind and sand. Tile layer 1 also has a good drainage function. Rainwater will naturally flow along the tiles to the eaves 11, reducing the erosion of the lower structure by water retained on the roof, and further enhancing the protective effect of the roof. The waterproof layer 2 is tightly attached to the bottom of the tile layer 1 and is made of waterproof membrane. It is fixedly connected to the bottom surface of the tile layer 1 by hot melting. Through hot melting, the connection between the waterproof layer 2 and the tile layer 1 is more firm, forming a tight waterproof barrier, which can effectively block rainwater penetration and prevent rainwater from entering the lower structure, thereby avoiding the problem of moisture, mildew and even structural damage inside the building. The waterproof membrane itself has good flexibility and weather resistance, and can adapt to changes in various climatic conditions to maintain long-term waterproofing. The water effect greatly extends the service life of the roof structure and reduces the need for subsequent maintenance. The ventilation layer 3 optimizes the air flow on the roof, removes heat and moisture, and keeps the inside of the roof dry and cool. The ventilation layer 3 includes a frame 31 and a connecting block 32. An air inlet 312 is provided on the side of the frame 31, which is located below the eaves 11 to allow outside air to enter the inside of the roof. A vent 311 is provided on the other side of the frame 31, away from the air inlet 312 and connected to the connecting block 32. An exhaust vent 322 is provided on the connecting block 32, and the exhaust vent 322 is located at the ridge. With the help of the natural convection principle of air, hot air and moisture are discharged from the exhaust vent 322, thereby realizing self-convection in the house. Natural ventilation. Through this design, external cold air enters the roof ventilation layer 3 from the air inlet 312, takes away the hot air and is discharged through the exhaust vent 322. Natural convection allows the roof to maintain a lower temperature in summer, reducing the use load of air conditioning in the building. In winter, the ventilation system can effectively remove moisture, avoid condensation or mildew problems caused by moisture, and ensure the stability of the ventilation system. The air inlet 312 and the exhaust vent 322 are both equipped with a stainless steel dustproof net 6, which can effectively block dust, leaves and other debris from entering, keeping the ventilation passage unobstructed. The stainless steel dustproof net 6 has good corrosion resistance, can be used for a long time and is not easy to rust, reducing maintenance work and ensuring ventilation. The wind system is long-lasting and effective. The thermal insulation layer 4 is made of polyurethane foam and silica aerogel 42 materials. Polyurethane foam is a lightweight material with excellent thermal insulation performance. It can effectively prevent external heat from being transferred to the room through the roof, lowering the indoor temperature in summer and reducing the air conditioning load, thereby achieving energy saving effects. Silica aerogel 42 is an advanced nanomaterial known for its extremely low thermal conductivity. It can further enhance the thermal insulation performance of the roof and fill it in the polyurethane foam to form a multi-layered thermal barrier in the thermal insulation layer. Silica aerogel 42 not only has excellent thermal insulation performance, but can also absorb some moisture through its porous structure to prevent moisture accumulation.This improves the overall performance of the thermal insulation layer 4. In winter, the thermal insulation layer 4 also plays an important role by reducing indoor heat loss, maintaining indoor warmth, and thus reducing the energy consumption of the heating system, allowing the building to maintain a suitable temperature in both winter and summer, significantly improving living comfort while reducing the building's energy consumption. The support layer 5 is located at the bottom layer of the entire roof structure and is made of reinforced concrete, providing strong structural support. Reinforced concrete materials have excellent strength and durability and can withstand various loads on the roof, including its own weight, the weight of the tile layer 1, snow accumulation, wind pressure and other external forces, ensuring the stability and safety of the roof structure. In addition, reinforced concrete materials have good seismic resistance. For antique buildings, the seismic resistance of the support layer 5 can effectively protect the safety of the building during natural disasters such as earthquakes, avoid damage to the roof structure, and ensure the overall stability and long-term use of the antique building.
