Description
Technical Field

[0002] With rising cultural confidence and the diversification of architectural aesthetics, new Chinese-style antique buildings, primarily constructed of concrete, have found widespread application in cultural venues, tourism towns, and commercial districts, merging traditional features with modern engineering performance. As a signature component of antique roofs, eaves not only support the roof and guide water, but also convey the aesthetic value of traditional architecture through their flowing curves and ingenious shapes, becoming one of the core vehicles for expressing the style of antique architecture.
[0003] At present, the roofs of antique buildings often adopt a large slope design of five points or more. In the snowy areas in the north, the snow on the roof is easy to slide down the slope due to gravity in winter, which may not only cause the roof tiles to loosen, but also pose a safety risk of falling snow and injuring people. Most of the existing snow-blocking facilities are installed later and lack integrated fixation with the roof structure. They are easy to deform or fall off due to the pressure of snow, making it difficult to effectively prevent risks. In addition, the roofs of existing antique buildings are prone to leakage and eaves problems. There are common problems such as insufficient laying range of waterproof membranes, unreasonable control of the length of drip tiles, and loose connection between the waterproof layer and tiles. As a result, rainwater penetrates into the structure along the eaves gaps, causing quality problems such as decay of wooden components and moisture on the walls, affecting the service life of the building.

The slider lining 2 is constructed of fine stone concrete, and the waterproof layer 2-1 utilizes polypropylene or TS waterproof membrane. The height of the structural anti-slip assembly 1-1 is the same as the finished surface of the insulation layer 2-2 on the roof main body 1. The structural anti-slip assembly 1-1 and the reinforced concrete structure of the roof main body 1 are cast in situ. The eaves rafter assembly 4 and the facade decorative assembly 6 are constructed of extruded board.
[0031] First, the structural anti-slip component 1-1 and the roof main body 1 are cast in one step using reinforced concrete, which avoids the splicing gaps required for secondary construction in the later stage, strengthens the structural integrity of the roof eaves edge, and can effectively resist slippage or settlement caused by roof loads and external stress, providing a solid foundation for the subsequent installation of waterproofing, thermal insulation and the interior decoration kit 6. Secondly, the slider lining 2 is applied, and the waterproof layer 2-1, the thermal insulation layer 2-2 and the fine stone concrete nail holding layer 2-3 are laid in sequence, so that the waterproof layer 2-1 is reversed to the air-facing facade of the structural anti-slip component 1-1; a fine stone concrete base layer is formed by applying the slider lining 2, which provides a pre-embedded carrier for the steel embedded parts of the snow fence component 3, thereby ensuring the fixing strength of the snow-blocking structure; the waterproof layer 2-1 is reversed to the air-facing facade of the structural anti-slip component 1-1, and combined with the full covering treatment of the exposed part of the slider lining 2, a three-dimensional waterproof barrier is formed, which greatly reduces the risk of rainwater leakage; the thermal insulation layer 2-2 and the fine stone concrete nail holding layer 2-3 laid in sequence not only meet the roof insulation requirements, but also provide a solid load-bearing base for the dry hanging of tiles.

The surface of the extruded board of the eaves flying rafter assembly 4 is provided with an anti-cracking mortar plaster layer, and an alkali-resistant mesh cloth is pressed into the plaster layer. The length of a single extruded board in non-corner areas is not less than 1m. The surface of the extruded board of the eaves flying rafter assembly 4 is provided with an anti-cracking mortar plaster layer, and an alkali-resistant mesh cloth is pressed into the plaster layer. The length of a single extruded board in non-corner areas is not less than 1m. The facade decoration kit 6 includes a facade decoration board 6-1, which is made of extruded board material and also serves as exterior wall insulation. The upper part of the facade decoration board 6-1 is glued to the end of the eaves rafter assembly 4, and the lower part is anchored into the exterior wall through expansion rivets 6-2.
[0033] Prepare the eaves flying rafter assembly 4 and the facade decoration kit 6, and fix them to the corresponding nodes of the plaster base 4-4 and the exterior wall by gluing, expansion rivet 1 4-3 and expansion rivet 2 6-2 respectively; the eaves flying rafter assembly 4 and the facade decoration kit 6 are centrally processed in the extruded board factory, which can accurately match the design shape and reduce on-site cutting losses; the dual fixing method of full gluing and expansion rivets ensures the firm connection between the assembly and the plaster base 4-4 and the exterior wall, and the subsequent anti-cracking mortar finishing and mesh cloth reinforcement treatment can effectively prevent the assembly from deformation and falling off. At the same time, the extruded board material significantly reduces material costs and improves construction efficiency. After the snow fence assembly 3 is installed, the eaves flying rafter assembly 4 and the facade decoration kit 6 are subjected to exterior painting construction, which can unify the appearance style of the antique building eaves and facade, and enhance the flatness and color consistency of the decorative surface; the coating layer can isolate the erosion of external water vapor, ultraviolet rays, etc., protect the extruded board assembly and the base structure, extend the service life of the decorative components, and improve the beauty and durability of the overall building;
[0034] Example 3: The snow fence assembly 3 includes a steel embedded part 3-1 and an electric heating structure. The steel embedded part 3-1 is pre-embedded in the slider lining angle 2 at intervals. A fence bracket 3-2 is fixed to the steel embedded part 3-1. A snow fence 3-3 is installed on the top of the fence bracket 3-2. The snow fence 3-3 is a metal component. An electric heating wire is installed along its entire longitudinal length. The electric heating wire is connected to a safe voltage power supply, a transformer and a microcomputer time-controlled switch; the tile block 7 is installed on the fine stone concrete nail holding layer 2-3 by a dry hanging method, and each tile block 7 is provided with a windproof buckle; the corner 8 is a finished component spliced and shaped by wet mortar, and the length of the drip tile 5 protruding from the eaves board 4-1 is 5 to 7 cm.
[0035] The tile blocks 7 are installed using the dry hanging method and windproof buckles are installed, the corners 8 are wet-mounted in place, and the snow fence components 3 and electric heating wires are installed at the same time; the tile blocks 7 are installed using the dry hanging method and are equipped with windproof buckles, which can resist the tiles from falling off due to external forces such as strong winds, thereby improving the stability of the roof tile system; the corners 8 are shaped by splicing with wet mortar, which can accurately fit the curvature of the roof corners, ensuring the coordination and aesthetics of the traditional eaves shape; the simultaneous installation of the snow fence components 3 can be firmly fixed by relying on pre-buried steel embedded parts, and the laying of electric heating wires provides a guarantee for the rapid melting of snow in winter, effectively preventing the risk of snow sliding and injuring people.
[0036] Working Principle: Based on the main roof body 1, the structural anti-slip component 1-1 and the main roof body are cast in one piece using reinforced concrete, forming an integrated load-bearing frame. The rigidity of concrete is used to resist roof loads and external stresses, preventing the eaves edge from slipping or settling due to uneven stress, and providing a stable installation foundation for all subsequent functional components and decorative elements. The slider lining 2 is cast with fine stone concrete on the inside of the structural anti-slip component, which not only strengthens the structural transition of the roof edge, but also provides a pre-embedded carrier for the steel embedded parts 3-1 of the snow fence component 3. The bond between the embedded parts and the concrete ensures the fixed strength of the snow-blocking structure. The snow fence component 3 relies on the steel embedded parts 3-1 embedded in the slider lining to achieve a rigid connection with the roof structure. The fence bracket 3-2 supports the snow fence 3-3 to form a horizontal barrier that can directly prevent accumulated snow from sliding down the slope. At the same time, the electric heating conductors laid along the entire longitudinal length of the fence are activated in low winter temperatures through the 24V safety Voltage power supply and microcomputer time-controlled switch control are used to utilize the heat energy converted from electrical energy to accelerate the melting of snow near the fence, so that the snow is discharged in the form of liquid water along the roof drainage system, avoiding safety accidents caused by excessive snow accumulation or sudden sliding; the waterproof layer 2-1 wraps the exposed part of the slider lining 2 and is reversed to the air-facing facade of the structural anti-slip component 1-1, forming a three-dimensional waterproof barrier with full bottom coverage and reversed facade, blocking the path of rainwater seeping in from the gaps at the edge of the eaves; the insulation layer 2-2 and the fine stone concrete nail-holding layer 2-3 are sequentially covered with the waterproof layer, which not only realizes the roof insulation function, but also provides a solid base for the dry hanging of the tiles 7. At the same time, the precise design of the drip tile 5 protruding from the eaves board 4-1 by a distance of 5 to 7 cm can guide rainwater to drip along the end of the tile body, avoiding rainwater from flowing back to the base layer along the eaves, and cooperating with the windproof buckle of the dry-hanging tile 7 to form a double waterproof protection against leakage and backflow; the eaves flying rafter assembly 4 and the facade decoration kit 6 are made of extruded board material, and their light weight and easy processing characteristics are used to accurately restore the traditional flying rafter shape; through the dual fixing method of full gluing and expansion rivet 1 4-3 and expansion rivet 2 6-2 anchored into the base layer with an anchor depth of not less than 5 cm, the extruded board assembly is tightly combined with the plaster base layer 4-4 and the exterior wall, and combined with anti-cracking mortar finishing and alkali-resistant mesh cloth reinforcement treatment, it can effectively resist deformation or falling off caused by external temperature difference and wind pressure. At the same time, the extruded board replaces solid wood or aluminum instead of wood to greatly reduce material costs. Corner angles 8 are shaped using wet mortar splicing, leveraging the mortar's plasticity to precisely conform to the roof's corner arc, ensuring harmony with the overall eaves curve. Tiles 7 are dry-hung on a nailing layer and equipped with windproof clips, ensuring both the stability of the tile system and the layered texture of a traditional tiled roof. Exterior coating creates a protective layer, shielding the extruded board components from moisture and UV rays, while unifying the eaves and facade, achieving both functional protection and aesthetic appeal.
