Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and specifically discloses a parapet wall with a large span and beamless cantilevered eaves. Background Art

[0002] Parapet wall long span beamless eaves refers to the parapet wall (i.e. the low wall at the edge of the roof) in architectural design, which adopts a long span eaves structure without the support of beams and columns. This design can provide a larger indoor space, while reducing the structural occupancy, increasing the aesthetics and practicality. In the specific implementation, parapet wall long span beamless eaves may involve the following aspects:

[0003] Structural design: The load-bearing and stability of the cantilevered eaves structure are the key to the design. It is necessary to ensure that the cantilevered eaves can withstand various natural forces (such as wind and snow loads) and human loads without the need for beams and columns;

[0004] Material selection: Materials with high strength, light weight and good durability should be selected, such as reinforced concrete, steel structure or new composite materials;

[0005] Construction technology: The construction technology requirements for large-span beamless cantilevered eaves are high, requiring precise construction control and quality inspection to ensure the reliability of the structure;

[0006] Aesthetic requirements: The design of the eaves should not only consider practicality, but also the aesthetic coordination with the overall style of the building;
