BRIEF DESCRIPTION OF DRAWINGS
[0014] Figure 1This is a schematic diagram of the secondary cantilever structure of the frame building provided in this embodiment of the utility model.
[0015] Figure 2 This is a schematic diagram of a secondary cantilever structure of a frame building provided in another embodiment of the present invention. Detailed Implementation
[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0017] like Figure 1 The diagram shown is a schematic of a secondary cantilever structure for a frame building according to an embodiment of the present invention. This structure can be applied to frame buildings, such as residences and hotels, which include a main frame 10. The secondary cantilever structure of the frame building in this embodiment includes a primary cantilever component and a secondary cantilever component. Both the primary and secondary cantilever components are reinforced concrete structures, and are integrally cast with the main frame 10 of the frame building (the reinforcing bars in the primary and secondary cantilever components are connected to the reinforcing bars in the main frame 10).
[0018] The aforementioned primary cantilever assembly includes a primary edge sealing beam 22 and two primary cantilever beams 21, and the secondary cantilever assembly includes a secondary edge sealing beam 32 and two secondary cantilever beams 31. The primary edge sealing beam 22, primary cantilever beam 21, secondary edge sealing beam 32, and secondary cantilever beam 31 are located on the same side of the main frame 10 and at the same elevation as one of the nearest side frame beams 12. That is, the primary edge sealing beam 22, primary cantilever beam 21, secondary edge sealing beam 32, secondary cantilever beam 31, and one of the nearest side frame beams 12 of the main frame 10 are at the same horizontal height.
[0019] The first ends of the two primary cantilever beams 21 are respectively connected to two adjacent side frame columns 11 of the main frame 10 (the main reinforcement of the primary cantilever beam 21 is fixed to the main reinforcement of the side frame column 11 or to the main reinforcement of the internal frame beam of the coaxial column of the primary cantilever beam 21), and the two primary cantilever beams 21 are perpendicular to the side frame beam 12 between the two side frame columns 11, that is, the two primary cantilever beams 21 are perpendicularly connected to the two side frame columns 11. The two ends of the primary edge sealing beam 22 are respectively connected to the tail ends of the two primary cantilever beams 21 (the main reinforcement of the primary edge sealing beam 22 is fixed to the main reinforcement of the primary cantilever beam 21) and are parallel to the side frame beam 12 of the main frame 10, that is, the primary edge sealing beam 22 is perpendicularly connected to the two primary cantilever beams 21, and the length of the primary edge sealing beam 22 is equal to the length of the side frame beam 12 between the two adjacent side frame columns 11.
[0020] Two secondary cantilever beams 31 intersect with the primary edge sealing beam 22. When the ratio of the length of the primary cantilever beam 21 to the length of the primary edge sealing beam 22 is less than or equal to 0.5, the first ends of the two secondary cantilever beams 31 are connected to the edge frame beam 12 between two adjacent edge frame columns 11 of the main frame 10 (the main reinforcement of the two secondary cantilever beams 31 is fixed to the main reinforcement of the edge frame beam 12). For example, the two secondary cantilever beams 31 intersect the primary edge sealing beam 22 perpendicularly, and the first ends of the two secondary cantilever beams 31 are vertically connected to the edge frame beam 12 between the two edge frame columns 11. The two ends of the secondary edge sealing beam 32 are connected to the tail ends of the two secondary cantilever beams 31, and are parallel to the primary edge sealing beam 22. The vertical projection of the secondary edge sealing beam 32 onto the primary edge sealing beam 22 is located between the two ends of the primary edge sealing beam 22, that is, the length of the secondary edge sealing beam 32 is less than the length of the primary edge sealing beam 22. Furthermore, the distance between the two ends of the vertical projection of the secondary edge sealing beam 32 onto the primary edge sealing beam 22 and the two ends of the primary edge sealing beam 22 on the same side is equal, that is, the distance between the two ends of the secondary edge sealing beam 32 and the two corresponding ends (i.e. the ends on the same side) of the primary edge sealing beam 22 is equal.
[0021] Two secondary cantilever beams 31 intersect with the primary edge sealing beam 22 respectively. When the distance between the secondary edge sealing beam 32 and the primary edge sealing beam 22 is greater than half the length of the primary cantilever beam 21, the two secondary cantilever beams 31 are perpendicular to the primary edge sealing beam 22 respectively. The first ends of the two secondary cantilever beams 31 are connected to the edge frame beam 12 between two adjacent edge frame columns 11 of the main frame 10 respectively. The two ends of the secondary edge sealing beam 32 are connected to the tail ends of the two secondary cantilever beams 31 respectively.
[0022] Similarly, when the two ends of the vertical projection of the secondary edge sealing beam 32 onto the primary edge sealing beam 22 are equidistant from the two ends of the primary edge sealing beam 22 on the same side, and the ratio of the distance between the primary edge sealing beam 22 and the secondary edge sealing beam 32 to the difference in length between the primary edge sealing beam 22 and the secondary edge sealing beam 32 is less than or equal to 0.4, the first ends of the two secondary cantilever beams 31 are perpendicularly connected to the side frame beams 12 between the two adjacent side frame columns 11 of the main frame 10, and the two ends of the secondary edge sealing beam 32 are connected to the tail ends of the two secondary cantilever beams 31, and are parallel to the primary edge sealing beam 22.
[0023] The secondary cantilever structure of the aforementioned frame building is supported by two primary cantilever beams 21 connected to the two side frame columns 11 of the main frame 10, and primary edge sealing beams 22 connected to the ends of the two primary cantilever beams 21. The secondary cantilever structure is also supported by two secondary cantilever beams 31 that intersect with the primary edge sealing beams 22 and the secondary edge sealing beams 32 connected to the ends of the two secondary cantilever beams 31. The force of the secondary cantilever beams 31 can be distributed to the primary edge sealing beams 22 and the main frame 10. While ensuring the strength of the secondary cantilever structure, the safety, applicability, economy and aesthetics of the overall cantilever structure are improved.
[0024] like Figure 2 As shown, in one embodiment of this utility model, the secondary cantilever structure of the frame building also includes a primary cantilever component and a secondary cantilever component that are integrally cast with the main frame of the frame building. Figure 1 The difference in the Chinese embodiment is that the ratio of the length of the primary cantilever beam 21 to the length of the primary edge sealing beam 22 is greater than 0.5, and the ratio of the distance between the primary edge sealing beam 22 and the secondary edge sealing beam 32 to the difference in length between the primary edge sealing beam and the secondary edge sealing beam is greater than 0.4. In this case, the first ends of the two secondary cantilever beams 31 are respectively connected to the primary cantilever beam 21 on the same side (the main reinforcement of the two secondary cantilever beams 31 is fixed to the main reinforcement of the two primary cantilever beams 21 respectively), that is, the two secondary cantilever beams 31 are not perpendicularly connected to the primary edge sealing beam 22 and the primary cantilever beam 21.
[0025] Specifically, to ensure structural stability, the angle between the two secondary cantilever beams 31 and the primary edge sealing beam 22 is between 40° and 50°.
[0026] Through the above structure, the stress on the secondary cantilever beam 31 can be distributed to the primary edge-sealing beam 22 and the primary cantilever beam 21, thus ensuring structural strength. Furthermore, compared to... Figure 1 In this embodiment, the above structure allows for a relatively short length of the secondary cantilever beam 31, thereby saving building materials.
[0027] Specifically, the tail ends of the aforementioned secondary cantilever beams 31 are respectively connected between the two ends of the secondary edge sealing beams 32 (the main reinforcement bars of the two secondary cantilever beams 31 are respectively fixed to the main reinforcement bars of the secondary edge sealing beams 32), and the two ends of the secondary edge sealing beams 32 are respectively connected to the primary edge sealing beams 22 through small edge beams 33 or floor slabs. Through the above structure, the integrity and structural strength of the secondary edge sealing beams 32 can be improved.
[0028] The cross-sectional dimensions and internal reinforcement of the aforementioned primary edge sealing beam 22, primary cantilever beam 21, secondary edge sealing beam 32, and secondary cantilever beam 31 can be calculated according to building codes and will not be elaborated here.
[0029] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
