[0005] This utility model embodiment provides a prefabricated balcony, which includes a prefabricated balcony slab and steel beams. The prefabricated balcony slab is a prefabricated, integrated structure and is connected to the steel beams. The steel beams are connected to the prefabricated floor slabs of the building to be constructed. The prefabricated balcony slab is provided with several reinforcing bars to improve overall strength. It can be seen that by implementing this utility model embodiment, on-site wet work and cross-operations are reduced, installation efficiency is improved, steel consumption costs are reduced, project quality and construction efficiency are enhanced, and the industrialization level of the steel structure prefabricated system is further improved, thereby achieving structural greening.

[0015] Please refer to Figures 1-2. Figure 1 is a cross-sectional structural diagram of the prefabricated balcony provided in the embodiment of the present invention; Figure 2 is a partial structural diagram of the side connection section of the prefabricated balcony provided in the embodiment of the present invention.

[0016] As shown in Figures 1 and 2, this utility model embodiment provides a prefabricated balcony 100, which includes a prefabricated balcony slab 1 and a steel beam; the prefabricated balcony slab 1 is a prefabricated integral structure and is connected to the steel beam; the steel beam is connected to the prefabricated floor slab 10 of the building to be constructed; wherein, the prefabricated balcony slab 1 is provided with a number of steel bars 2 to improve the overall strength.

[0017] In this embodiment, as shown in Figures 1-2, the precast balcony slab 1 is integrally cast with concrete in the factory, and the several steel bars 2 are embedded inside the concrete structure of the precast balcony slab 1. Therefore, the precast balcony slab 1 is a precast integrated concrete component in the factory, forming a steel-concrete composite load-bearing system, ensuring the rigidity and durability of the floor slab and improving safety.

[0018] Furthermore, before concrete pouring, integrated pipelines can be pre-embedded in the precast balcony slab 1, and terminal interfaces of equipment such as water supply and drainage, electrical, gas, heating, and ventilation pipes can be integrated simultaneously. That is, the integrated pipelines should be integrated in the factory and can be directly connected on the construction site, improving applicability and efficiency.

[0019] The prefabricated balcony 100 provided by this utility model is applied in the field of building engineering, specifically adapted to steel structure buildings. The prefabricated balcony slab 1 replaces the current construction method. Its floor slab reinforcement is similar to that of traditional cast-in-place concrete structures, saving the amount of structural steel bars in the truss floor slab. It is estimated that the amount of steel used will be saved by about 10%-15%, achieving material and energy conservation, and thus achieving green structure.

[0020] In one embodiment, as shown in Figures 1-2, the prefabricated balcony slab 1 includes a horizontal portion and a vertical portion, with one side of the horizontal portion connected to one end of the vertical portion.

[0022] In one embodiment, as shown in Figures 1-2, the edges of the horizontal portion, except for the side connected to the vertical portion, are stepped.

[0023] In this embodiment, as shown in Figures 1-2, the other sides are the three other sides on the horizontal part that are not connected to the vertical part; the edges of the other sides are set in a stepped shape to provide a foundation for subsequent connection with the precast floor slab 10 of the building to be constructed, thereby improving efficiency and the stability of the connection.

[0024] In one embodiment, as shown in Figures 1-2, the edges of the other sides expose the plurality of reinforcing bars 2.

[0025] In this embodiment, as shown in Figures 1-2, the plurality of reinforcing bars 2 are arranged in a cross pattern, and some of the plurality of reinforcing bars 2 are located inside the precast balcony slab 1, while others are exposed outside the precast balcony slab 1, i.e., the edges of the other sides expose the plurality of reinforcing bars 2. Therefore, the reinforcing bars on the precast balcony slab can be connected to the precast floor slab 10 of the building to be constructed through subsequent concrete pouring, thereby improving the overall stability and strength of the connection.

[0026] In one embodiment, as shown in Figures 1-2, a connecting bolt 3 is provided on the side of the vertical part away from the horizontal part, and one end of the connecting bolt 3 is embedded in the vertical part.

[0029] In this embodiment, as shown in Figures 1-2, the post-pouring strip 4 is used to achieve a stable connection between the precast balcony slab 1 and the precast floor slab 10 of the building to be constructed using concrete during on-site operations, ensuring safety and improving efficiency.

[0030] The stirrups 5 are manufactured in the factory and then transported to the construction site to be welded onto the steel beams, thereby further improving the overall safety and efficiency; and reducing the amount of wet work and cross-construction procedures on site, reducing labor costs and achieving better economic benefits.

[0031] In one embodiment, as shown in Figures 1-2, the precast balcony 100 further includes studs 6; the studs 6 are disposed inside the post-cast strip 4 and are used to connect with the steel beam.

[0032] In this embodiment, as shown in Figures 1-2, during on-site construction, before pouring concrete for the post-pouring strip 4, the studs 6 are placed in a preset position, and then the concrete for the post-pouring strip 4 is poured. Subsequently, the studs 6 are used to connect with the steel beam to improve stability and efficiency.

[0033] In one embodiment, as shown in Figures 1-2, the steel beam includes a first steel beam 7, a second steel beam 8, and a steel plate 9, wherein the first steel beam 7 is connected to the second steel beam 8 through the steel plate 9.

[0034] In this embodiment, as shown in Figures 1-2, the first steel beam 7, the steel plate 9, and the second steel beam 8 are combined to form the steel beam.

[0038] In one embodiment, as shown in Figures 1-2, the top of the second steel beam 8 is connected to the precast balcony slab 1, the studs 6, and the precast floor slab 10 of the building to be constructed.

[0039] In this embodiment, as shown in Figures 1-2, the second steel beam 8 is connected to the steel plate 9; the top of the second steel beam 8 is connected to the precast balcony slab 1, the studs 6 and the precast floor slab 10 of the building to be constructed, thereby improving stability and efficiency; the second end of the first steel beam 7 is connected to the steel plate 9.
