Description

Technical Field

[0001] The present application belongs to the field of architectural design and construction technology, and specifically relates to a self-flowing reinforced concrete cantilevered canopy structure. Background Art

[0002] Awnings, as part of a building, are not only for sheltering from wind and rain, but also an important part of the building's shape. In the design of awnings, it is often necessary to use various techniques and skills to achieve the function of the awning while meeting the needs of the architectural style.

[0003] The structural design of a canopy must not only fit in with the overall style of the building but also be stable and safe. Designers can achieve complex shapes through innovative structural design and engineering techniques. Such designs not only meet functional requirements but also showcase the artistic beauty of structural design.

[0004] Awnings are cantilever structures. When subjected to external forces, the force is typically perpendicular to their length, as one end is fixed and the other is free. The force acting on the end of the awning is greater, and the other end is unsupported, so it must rely on its own strength to withstand external forces. Furthermore, the forces acting on the awning are complex, often exhibiting bending, shearing, or torsion. Because one end is fixed and the other is free, the awning may experience uneven stress distribution when subjected to external forces, resulting in significant deformation and displacement. Furthermore, since the awning is a statically determinate structure with no excess redundancy, if the fixed end is damaged by force, it can easily fall, causing a safety accident. Utility Model Content

[0005] The embodiment of the present application provides a self-flowing reinforced concrete cantilever canopy structure, which solves the problem in the prior art that the canopy structure is heavy and requires surface slope, resulting in heavy load and material waste.

[0006] In order to achieve the above-mentioned object, the embodiment of the present invention provides a self-flowing reinforced concrete cantilevered canopy structure, wherein the upper end of the reinforced concrete beam is connected to the fixed end of the canopy, the cantilevered end of the canopy extends outward, a parapet is provided on the upper part of the canopy, and the lower end of the parapet is connected to the cantilevered end of the canopy;

[0007] The bottom surface of the awning is set horizontally, the top surface of the awning is set inclinedly, the width of the cantilevered section of the awning is L, the thickness of the fixed end of the awning is S=(1 / 10~1 / 15)×L, and the thickness of the cantilevered end of the awning is D=S-(20~50mm).

[0008] In a possible implementation, the thickness of the parapet is 80-150 mm.

[0009] In a possible implementation, the canopy is a reinforced concrete structure, and steel bars are provided in the bottom and surface of the canopy. The steel bars of the bottom and surface are connected to the steel bars of the reinforced concrete beam.

[0010] In a possible implementation, the steel bars of the bottom and top of the slab include width-direction steel bars and length-direction steel bars, the width-direction steel bars are parallel to the width direction of the awning, and the length-direction steel bars are parallel to the length direction of the awning;

[0011] The width direction steel bars are connected to the length direction steel bars, and the width direction steel bars are connected to the steel bars of the reinforced concrete beam.

[0012] In a possible implementation, ends of the width-direction steel bars of the slab bottom and the slab surface are both provided with bent sections.

[0013] In one possible implementation, vertical steel bars and horizontal steel bars are provided in the parapet, the vertical steel bars are connected to the horizontal steel bars, the bent section at the lower end of the vertical steel bars is located in the cantilevered end of the canopy, and the upper end of the vertical steel bars is provided with a bent section.

[0015] The present invention provides a self-flowing reinforced concrete cantilever canopy structure. The canopy's structure is determined by the width of the canopy's cantilever section, and the canopy's panels are designed as variable-thickness panels. This design eliminates the need for drainage and slope adjustment, thereby reducing the load on the surface layer and lowering the structure's deadweight. Furthermore, this design conforms to structural stresses, effectively increasing the cross-sectional area of ​​the canopy's fixed end, thereby enhancing structural safety. While meeting relevant building dimensional requirements, this optimized joint structure not only simplifies the canopy structure but also ensures high waterproof reliability, facilitates construction, and maintains cost control.

Furthermore, it avoids the problem of increased internal forces at the cantilever end caused by increased canopy load, which reduces structural safety. The present invention achieves high waterproof reliability and eliminates the need for surface slope adjustment. The use of variable-thickness panels for waterproofing the canopy allows for self-flowing drainage, while also reducing structural loads, making the structure more compatible with structural stresses, enhancing structural safety, saving building materials, and simplifying construction.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

The terms "first", "second" and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. In addition, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be a communication between the internal parts of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present invention can be understood according to the specific circumstances.

[0021] like Figure 1 As shown, the self-flowing reinforced concrete cantilevered canopy structure provided by the embodiment of the utility model has the upper end of the reinforced concrete beam 1 connected to the fixed end 3 of the canopy 2, the cantilevered end 4 of the canopy 2 extends outward, the parapet 5 is arranged on the upper part of the canopy 2, and the lower end of the parapet 5 is connected to the cantilevered end 4 of the canopy 2.

[0023] It should be noted that the structure of the canopy 2 of the present invention is determined by the width of its cantilevered section. The canopy 2 panel is designed as a variable-thickness panel. This eliminates the need for drainage and sloping, thereby reducing the load on the surface layer and lowering the deadweight of the structure. Furthermore, this design complies with structural stresses, indirectly increasing the cross-sectional area of ​​the canopy's fixed end 3 and enhancing structural safety. While meeting relevant building dimensional requirements, this optimized joint structure not only simplifies the canopy structure but also ensures high waterproof reliability, facilitates construction, and maintains cost control. This avoids the problems of existing canopies with waterproofing and drainage functions, which result in a heavy structure and the need for surface sloping, resulting in high loads and material waste. It also avoids the problem of increased internal forces at the cantilevered end 4 caused by increased canopy load, which reduces structural safety. The present invention achieves high waterproof reliability and reduces surface sloping. The use of variable-thickness panels for waterproofing the canopy allows for self-draining, while also reducing structural loads, making the structure more compatible with structural stresses, increasing structural safety, saving building materials, and simplifying construction.

[0027] It should be noted that the steel bars of the slab bottom 6 and the slab surface 7 are connected to the steel bars of the reinforced concrete beam 1 , thereby improving the structural stability of the canopy 2 .

[0028] In this embodiment, the steel bars of the slab bottom 6 and the slab surface 7 include width-direction steel bars 8 and length-direction steel bars 9 . The width-direction steel bars 8 are parallel to the width direction of the canopy 2 , and the length-direction steel bars 9 are parallel to the length direction of the canopy 2 .

[0029] The width direction steel bars 8 are connected to the length direction steel bars 9 , and the width direction steel bars 8 are connected to the steel bars of the reinforced concrete beam 1 .

[0030] It should be noted that the width direction steel bars 8 and the length direction steel bars 9 can ensure the structural strength of the canopy 2 while minimizing the amount of steel bars used.

[0031] In this embodiment, the ends of the widthwise reinforcements 8 of the slab bottom 6 and the slab surface 7 are both provided with bent sections.

[0032] It should be noted that the bent section is used to increase the contact area and further improve the structural strength of the canopy 2.

The bent section of the vertical steel bar 10 is used to increase the contact area and further improve the structural strength of the parapet 5.
