Description

Technical Field

[0001] This utility model belongs to the field of architectural engineering technology. Specifically, it is an antique-style building eaves structure that combines a wooden structure and a concrete structure. Background Technology

[0002] With the revival of traditional Chinese culture and the advancement of urban landscape construction, antique-style buildings are playing an increasingly important role in modern urban public spaces. Especially in places such as temples, gardens, and cultural districts, the exterior of buildings needs to reflect traditional style while also meeting the safety, fire resistance, and energy-saving requirements of modern buildings.

[0003] Traditional wooden structures are widely used in historical buildings, with their eaves structures often composed of wooden rafters, brackets, and flying eaves, possessing excellent decorative and structural expressiveness. However, wood is flammable, has poor durability, and is prone to deformation and decay in environments with high humidity and large temperature differences. Therefore, in modern antique-style buildings, concrete structures are generally used as the main body to improve the overall fire resistance and structural safety.

[0004] However, traditional concrete eaves structures often lack the charm of ancient architecture and fail to meet people's aesthetic demands for cultural buildings. Existing technologies also include some eaves construction methods that combine wooden components with concrete structures, such as fixing wooden components with embedded parts or covering the concrete structure with decorative wooden panels. However, these methods mostly suffer from problems such as complex construction, weak connections, poor thermal insulation and waterproofing, and insufficient weather resistance, making them difficult to widely apply in practical engineering projects.

[0005] Therefore, there is an urgent need in the existing technology for a new type of eaves structure system that can both preserve the aesthetic beauty of the eaves of ancient buildings and improve structural safety, fire resistance, thermal insulation and construction convenience. Utility Model Content

[0006] The purpose of this utility model is to propose an antique-style building eaves structure that combines wood and concrete structures, which is easy to construct and has significant effects.

[0007] To achieve the above objectives, the technical solution of this utility model is: An antique-style building eaves structure combining wood and concrete structures includes a concrete eaves base, a wooden rafter installation structure, an insulation filling layer, a waterproof layer, a concrete protective layer, and roof tiles. The concrete eaves base layer: Anchor points for installing wooden rafters are pre-set at the eaves of the cast-in-place or precast concrete structure to ensure the structural bearing capacity and stability; The rafter installation structure consists of rafter strips evenly arranged along the eaves and anchored to the concrete structure by expansion bolts penetrating the bottom of the rafters. The insulation filling layer: Insulation boards are installed in the gaps between adjacent wooden rafters to effectively improve the thermal insulation performance of the eaves area, while also serving as structural filling and sound insulation. The waterproof layer: A waterproof membrane is installed on the top of the rafters and the surface of the insulation board to form a continuous waterproof surface layer to prevent rainwater leakage from affecting the durability of the wood structure; The concrete protective layer: A fine stone concrete protective layer is set on top of the waterproof layer. The protective layer is equipped with a steel mesh to enhance crack resistance and also serves as the base layer for the roof tiles. The roof tiles are laid on the concrete protective layer. The roof tiles are traditional roof tiles, such as blue tiles or glazed tiles, to restore the architectural style of traditional eaves.

[0008] The antique-style building eaves structure combining wood and concrete structures of this utility model can be further realized by the following technical measures.

[0009] The aforementioned antique-style building eaves structure combining wood and concrete structures, wherein the cross-sectional dimensions of the wooden rafters are ≥100mm×100mm.

[0016] (2) Inheriting traditional architectural aesthetics and enhancing cultural expression: The arrangement of the wooden rafters and the laying of the roof tiles continue the architectural language of the traditional eaves, making the antique buildings more historical and cultural in appearance, and suitable for temples, cultural blocks and other scenes with special requirements for architectural style.

[0017] (3) Excellent thermal insulation and energy-saving performance: The 100mm thick XPS insulation board filling the middle not only improves the thermal insulation performance of the eaves, but also effectively isolates the transmission of indoor and outdoor temperature differences, reduces energy consumption, and meets the green building energy-saving standards.

[0018] (4) Excellent waterproof performance, extending the service life of the structure. The 3+4mm SBS waterproof layer has good flexibility and crack resistance, which can effectively prevent the corrosion of wood structures and the deterioration of concrete caused by rainwater penetration, and greatly extend the service life of the eaves structure.
