[0019] Secondly, this utility model also discloses a steel structure, wherein the steel structure is provided with a cantilevered canopy as described in the first aspect above.

[0020] Compared with the prior art, the beneficial effects of this application are as follows:

[0021] This application discloses a cantilevered canopy applied to a steel structure and the steel structure itself. The steel structure includes frame columns, main floor beams, and secondary floor beams. The main floor beams are connected to the frame columns, and multiple secondary floor beams are spaced apart along the length of the main floor beams. The cantilevered canopy applied to the steel structure includes two hanging columns, a cantilever beam, and a force-transferring structure.

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] It should be noted that the terms "comprising" and "having," and any variations thereof, in the embodiments and accompanying drawings of this application are intended to cover non-exclusive inclusion.

[0029] To provide shelter from wind and rain, canopies are typically installed at building entrances. In related technologies, canopies are usually constructed in the following ways: First, the cantilever beams are placed at the locations of the main frame columns, with the cantilever beams extending directly from the columns. Second, a column is added directly from the ground floor to the second floor, from which the cantilever beams extend. However, placing the cantilever beams at the locations of the main frame columns restricts the canopy's placement, limiting flexibility. Adding columns, which form the main structure of the cantilever beams, often impacts floor functionality and hinders the layout of floor space and functions.

[0030] Based on this, this application discloses a cantilevered canopy for steel structures and the steel structure itself. The cantilevered canopy for steel structures disclosed in this application uses two suspended columns mounted on the main floor beam, with the cantilever beam mounted on these two columns. This allows the canopy's location to be flexible, not restricted by the position of the main frame columns, enabling flexible placement of the canopy without affecting floor functionality, thus benefiting the layout of floor space and functions. Furthermore, the cantilevered canopy for steel structures disclosed in this application incorporates a force-transfer structure. The two ends of this force-transfer structure are fixed to the suspended columns and the secondary floor beams, respectively, achieving force transfer between the suspended columns and the secondary floor beams. This avoids torque problems in the main floor beams caused by the bending moment of the cantilever beams, and the force transfer structure is simple.

[0031] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0032] Firstly, please refer to the following: Figure 1 , Figure 2 and Figure 3This application discloses a cantilevered canopy applied to a steel structure. The steel structure includes frame columns 3, a main floor beam 1, and multiple secondary floor beams 2. The main floor beam 1 is connected to the frame columns 3, and the multiple secondary floor beams 2 are spaced apart along the length of the main floor beam 1. The cantilevered canopy includes two hanging columns 4, a cantilever beam 5, and a force transmission structure 6. The two hanging columns 4 are spaced apart along the length of the main floor beam 1, and the cantilever beam 5 is disposed on the two hanging columns 4 and extends along the main floor beam 1 away from the secondary floor beams 2. The two ends of the force transmission structure 6 are fixed to the hanging columns 4 and the secondary floor beams 2, respectively, and the force transmission structure 6 is configured to transmit force between the hanging columns 4 and the secondary floor beams 2.

[0033] It is understandable that, in order to improve the stability of the cantilevered canopy, in addition to setting two hanging columns 4, more hanging columns 4 can be set. For example, there can be three, four, or five, etc., and this application does not make a specific limitation here.

[0034] Considering that the placement of the canopy would affect the floor space and functional layout, this application addresses this issue by installing two hanging columns 4 on the main floor beam 1 and placing the cantilever beam 5 on the two hanging columns 4. This allows the canopy placement to be flexible, not restricted by the position of the main frame columns, without affecting floor functionality, thus facilitating better floor space and functional layout. Furthermore, by installing a force-transfer structure 6 fixed to the hanging columns 4 and the secondary floor beam 2, force transfer between the hanging columns and the secondary floor beam is achieved. This avoids torque problems in the main floor beam caused by the bending moment of the cantilever beam 5, and the force transfer structure is simple.

[0035] In some embodiments, two hanging columns 4 are respectively connected to the two ends of the cantilever beam 5 along its length. The hanging columns 4 are used to suspend the cantilever beam. It is understood that, compared to connecting the two hanging columns 4 to the middle of the two ends of the cantilever beam 5 along its length, connecting the two hanging columns 4 to the two ends of the cantilever beam 5 along its length provides higher structural stability and makes the entire cantilever canopy structure more stable.

[0036] Optionally, the hanging column 4 can be made of any steel conforming to national standards, such as Q235, Q345, Q390, Q420, Q460, and Q345GJ steel, etc. It is understood that the type of steel used for the hanging column 4 can be selected according to actual needs due to different strength requirements, and this embodiment does not impose specific limitations on this.

[0037] In some embodiments, along the length of the main floor beam 1, two hanging columns 4 are respectively positioned corresponding to two secondary floor beams 2. It is understood that, compared to setting the two hanging columns 4 offset from the secondary floor beams 2, positioning them corresponding to the two secondary floor beams 2 simplifies the construction process and improves the structural stability of the canopy. Of course, in other embodiments, considering the floor space and functional layout, the hanging columns may not necessarily correspond to the secondary floor beams.

[0038] In some embodiments, there are two force transmission structures 6, each corresponding to a hanging column 4 and a secondary floor beam 2. It is understood that the force transmission structure 6 is used to fix the hanging column 4 and the secondary floor beam 2, therefore the number of force transmission structures 6 corresponds to the number of hanging columns 4 and secondary floor beams 2. Since there are two hanging columns 4 and two secondary floor beams 2, there are also two force transmission structures 6.

[0039] In other embodiments, in order to better balance the force and improve the force transmission efficiency, there may be multiple force transmission structures 6. For example, the number of force transmission structures 6 may be 3, 4 or 5, etc., and this application does not make a specific limitation.

[0040] In some embodiments, the force transmission structure 6 includes a first connecting plate 61, a second connecting plate 62, and a connecting rod 63. The first connecting plate 61 is fixed to the hanging column 4, the second connecting plate 62 is fixed to the secondary floor beam 2, and the two ends of the connecting rod 63 are respectively connected to the first connecting plate 61 and the second connecting plate 62. By configuring the force transmission structure to include the first connecting plate, the second connecting plate, and the connecting rod, the first connecting plate and the second connecting plate can be connected to the hanging column and the secondary floor beam respectively. Compared to the method where the connecting rod is directly connected to the hanging column and the secondary floor beam, the connecting plate has a larger connection area, thus increasing the connection area with the hanging column and the secondary floor beam, which is beneficial to improving the reliability and stability of the connection.

[0041] In other embodiments, the force transmission structure 6 may also be other structures capable of fixing the hanging column and the secondary beam of the floor, such as cables or tie rods.

[0042] Optionally, the first connecting plate 61 and the second connecting plate 62 can be circular, triangular, or rectangular, and this application does not limit the shape of them. It is understood that the first connecting plate 61 and the second connecting plate 62 only need to be able to be fixed to the hanging column and the secondary beam of the floor and meet the force transmission requirements, so there is no need to specifically limit the shape of the first connecting plate 61 and the second connecting plate 62.

[0043] Optionally, the first connecting plate 61, the second connecting plate 62, and the connecting rod 63 can be made of any steel conforming to national standards. For example, the materials of the first connecting plate 61, the second connecting plate 62, and the connecting rod 63 can be Q235, Q345, Q390, Q420, Q460, and Q345GJ steel, etc. It is understood that, due to different strength requirements, the specific type of steel used for the first connecting plate 61, the second connecting plate 62, and the connecting rod 63 can be selected according to actual needs.

[0044] Optionally, the connecting rod 63 can be fixedly connected to the first connecting plate 61 and the second connecting plate 62 respectively by bolts, so that the connecting rod is fixed to the first connecting plate and the second connecting plate. As another example, the connecting rod 63 can also be fixed to the first connecting plate 61 and the second connecting plate 62 by rivets. In addition, the connecting rod 63 can also be fixed to the first connecting plate 61 and the second connecting plate 62 by, for example, adhesive. Alternatively, both ends of the connecting rod can be welded to the first connecting plate and the second connecting plate.

[0045] In some embodiments, the connection position of the first connecting plate 61 and the hanging column 4 corresponds to the connection position of the cantilever beam 5 and the hanging column 4, so that the overall force of the canopy is more uniform and it is beneficial to the force transmission of the cantilever beam.

[0046] In some embodiments, the connecting rod 63 is inclined relative to the hanging column 4, and the included angle between the connecting rod 63 and the hanging column 4 is 45°-60°. This prevents instability of the canopy structure due to excessively large or small angles, and optimizes the efficiency of force transmission. For example, the included angle between the connecting rod 63 and the hanging column 4 may be 50°, 55°, etc.

[0047] In some embodiments, the secondary floor beam 2 includes an upper flange plate 21, a lower flange plate 22, and a stiffening plate 23, which connects the upper flange plate 21 and the lower flange plate 22. Along the length of the connecting rod 63, the axis of the connecting rod 63 intersects the centerline 41 of the hanging column 4, and the extended line of the axis of the connecting rod 63 is located at the connection point 24 between the lower flange plate 22 and the stiffening plate 23 of the secondary floor beam 2. This structural arrangement improves the overall stability of the canopy structure. Simultaneously, by providing the stiffening plate 23 in the secondary floor beam 2, the structural strength of the secondary floor beam can be enhanced, thereby increasing its load-bearing capacity.

[0048] In some embodiments, the distance between the top of the cantilever beam 5 and the top of the main floor beam 1 along the height direction of the frame column ranges from 1.5m to 3m. For example, it can be 1.6m, 2m, or 2.5m, etc.

[0049] Optionally, the cantilever beam 5 can be made of any steel conforming to national standards, such as Q235, Q345, Q390, Q420, Q460, and Q345GJ steel, etc. It is understood that the type of steel used for the cantilever beam 5 can be selected according to actual needs due to different strength requirements, and this embodiment does not impose specific limitations on this.

[0050] In some embodiments, in order to improve the rain shelter's resistance to wind and rain and its structural stability, the ratio of the length to the height of the cantilever beam 5 is less than or equal to 20.

[0051] This utility model embodiment is applied to a cantilevered canopy in a steel structure. Two hanging columns are installed on the main floor beam, and the cantilever beam is mounted on these two columns. Therefore, the canopy's location is not limited by the position of the main frame columns. Furthermore, this cantilevered canopy in the steel structure also incorporates a force-transfer structure. The two ends of this force-transfer structure are fixed to the hanging columns and the secondary floor beam, respectively, thereby enabling force transfer between the hanging columns and the secondary floor beam. This avoids the problem of torque on the main floor beam caused by the bending moment of the cantilever beam. Moreover, the force transfer structure is simple, allowing for the canopy installation without excessively affecting the stress analysis of the main floor beam, making the stress analysis of the main floor beam simple and controllable.

[0052] Secondly, please refer to the following: Figure 2 and Figure 4 , Figure 2 This is a schematic diagram of the overall structure of a cantilevered canopy applied to a steel structure, as disclosed in an embodiment of this utility model. Figure 4 This is a schematic diagram of the steel structure disclosed in an embodiment of the present invention. The steel structure includes a main floor beam 1, multiple secondary floor beams 2, and frame columns 3. The main floor beam 1 is connected to the frame columns 3. The multiple secondary floor beams 2 are spaced apart along the length of the main floor beam 1. The steel structure is equipped with a cantilevered canopy as described above. This steel structure allows for flexible placement of the cantilevered canopy, and has a clear force transmission path and a simple structure.

[0053] For example, the steel structure may include multiple frame columns arranged in two rows, with adjacent frame columns in the same row spaced apart. The floor slab may also consist of two main beams, one connected to one row of frame columns and the other connected to the other row. Multiple secondary floor beams connect the two main floor beams and are spaced apart sequentially along the length of the main floor beams.

[0054] The cantilevered canopy is located between two adjacent frame columns in the same row, and the cantilevered canopy has a certain height from the ground, which can be 3m-4.2m, for example, 3.2m, 3.5m, 4m or 4.8m, etc. Therefore, the cantilevered canopy is suspended in the air, which can reduce the impact on the floor space or functional layout.

[0055] The above provides a detailed description of the cantilevered canopy and steel structure applied to steel structures disclosed in the embodiments of this utility model. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the cantilevered canopy and steel structure applied to steel structures and its core ideas. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
