[0025] The utility model provides a cantilever beam and a structural column connection fixing structure. Figures 1 to 3 The utility model provides a specific embodiment of a cantilever beam and a structural column connection fixing structure.

[0026] like Figure 1 As shown, an embodiment of the utility model provides a cantilever beam and structural column connection fixing structure 100, including a cantilever beam 1, a structural column 2 and a connection assembly 3, the connection assembly 3 includes a first connection member 31 and a second connection member 32, the first connection member 31 and the second connection member 32 are arranged along the circumference of the structural column 2, the cantilever beam 1 is connected to the structural column 2 through the first connection member 31, and the second connection member 32 is connected to the cantilever beam 1 through the first connection member 31.

[0027] In the utility model, the connection assembly 3 includes a first connection member 31 and a second connection member 32, and the first connection member 31 and the second connection member 32 are arranged along the circumference of the structural column 2. The cantilever beam 1 is connected to the structural column 2 through the first connection member 31, and the second connection member 32 is connected to the cantilever beam 1 through the first connection member 31. The existing connection structure only fixes the cantilever beam 1 to the structural column 2 through a connection member arranged on one side of the structural column 2, resulting in the shear force generated by the gravity of the cantilever beam 2 being borne entirely by the connection member, and the bending moment and shear force resistance performance of the entire connection structure cannot meet the design requirements. The cantilever beam and structural column connection fixing structure 100 in the present application is additionally provided with a second connection member 32 on the circumferential side of the structural column 2, and the second connection member 32 is connected to the cantilever beam 1 through the first connection member 31, which can help share the gravity of the cantilever beam 1, thereby reducing the shear force applied to the first connection member 31, so that the connection assembly 3 can meet the bending moment and shear force resistance performance. The cantilever beam and structural column connection fixing structure 100 provided by the utility model solves the problem that the existing cantilever beam and structural column connection structure is difficult to meet the bending moment and shear force resistance performance.

[0028] It should be noted that the construction method of the cantilever beam and the structural column connecting the fixed structure 100 includes the following steps:

[0029] S10: prefabricate the connection assembly 3.

[0030] S20: Complete the vertical reinforcement construction of the structural column 2 and tie the stirrups below the installation position of the connection component 3.

[0031] S30: installing the first connecting member 31.

[0032] S40: Install the second connecting member 32.

[0033] S50: The template is supported from bottom to top along the structural column 2 until it is connected to the connecting component 3 to form a structural column mold.

[0034] S60: The cantilever beam 1 is fixedly connected to the first connecting member 31 .

[0035] S70: pouring concrete into the structural column mold from the top of the connecting component 3, and after the concrete strength reaches the standard, removing the template to complete the connection between the cantilever beam 1 and the structural column 2.

[0036] The specific structure of the first connecting member 31 is not limited, as long as the first connecting member 31 can connect the cantilever beam 1 and the structural column 2. For example, in some embodiments, Figure 2 and Figure 3As shown, the first connecting member 31 includes a structural column connecting section 311 and a cantilever beam connecting section 312. The structural column connecting section 311 is arranged on the circumferential side of the structural column 2, and the cantilever beam connecting section 312 is arranged at one end of the structural column connecting section 311 facing away from the structural column 2, and is connected to the cantilever beam 1. In this way, the structural column connecting section 311 and the cantilever beam connecting section 312 are connected to the structural column 2 and the cantilever beam 1 respectively. Since the structural column connecting section 311 and the cantilever beam connecting section 312 are connected to each other, the structural column 2 and the cantilever beam 1 are fixedly connected.

[0037] Furthermore, there is no restriction on the connection method between the cantilever beam connection section 312 and the structural column connection section 311, as long as the structural column 2 is fixedly connected to the cantilever beam 1. For example, in some embodiments, the cantilever beam connection section 312 and the structural column connection section 311 are integrally formed. Compared with the welding connection method, the integral forming makes the connection between the cantilever beam connection section 312 and the structural column connection section 311 more secure, and due to the influence of the gravity of the cantilever beam 1, the connection between the cantilever beam connection section 312 and the structural column connection section 311 will be subject to a large shear force. Compared with welding, the integral forming method can transfer more shear force to the structural column connection section 311.

[0038] Since the first connecting member 31 and the second connecting member 32 are connected only by welding and the connection area is small, the second connecting member 32 cannot share too much force on the first connecting member 31. Therefore, in some embodiments, Figure 2 As shown, the connection assembly 3 further includes a first reinforcement portion 33, which is disposed on the structural column connection section 311, and the first reinforcement portion 33 is respectively connected to the cantilever beam connection section 312 and the second connection member 32. In this way, the structural column connection section 311, the cantilever beam connection section 312 and the second connection member 32 are connected by the first reinforcement portion 33, so that the first connection member 31 and the second connection member 32 are more firmly connected, and the force received by the first connection member 31 can also be transmitted to the second connection member 32 through the first reinforcement portion 33, so that the second connection member 32 can share more force.

[0039] Furthermore, in some embodiments, Figure 1 and Figure 2As shown, a welding anchor bar 35 pre-embedded and extended into the structural column 2 is welded on the side of the structural column connection section 311 facing the structural column 2. Specifically, before pouring concrete into the structural column mold, the welding anchor bar 35 is welded to the structural column connection section 311 and pre-embedded and extended into the structural column 2 to avoid extending into the structural column 2 after the structural column 2 is cast and formed, thereby damaging the concrete and affecting the structural strength of the structural column 2.

[0040] In order to share more of the gravity on the cantilever beam 1, in some embodiments, as Figure 1 As shown, two second connectors 32 are provided, and the two second connectors 32 are arranged along the circumference of the structural column 2, and the two second connectors 32 are connected to the cantilever beam 1 through the first connector 31. In this way, two second connectors 32 are arranged on the circumferential side of the structural column 2, and the two second connectors 32 are respectively connected to the two sides of the first connector 31, which can avoid uneven force on the two sides of the first connector 31 on the one hand, and can further help share the gravity of the cantilever beam 1 on the other hand, thereby reducing the shear force on the first connector 31.

[0041] Furthermore, in order to make the connection between the first connecting member 31 and the two second connecting members 32 more stable, in some embodiments, as Figure 1 As shown, the connection assembly 3 further includes a second reinforcement portion 34 provided on the first connection member 31, the second reinforcement portion 34 is connected to the cantilever beam 1, and the second reinforcement portion 34 is respectively connected to the two second connection members 32. In this way, the cantilever beam 1, the first connection member 31 and the two second connection members 32 are connected by the second reinforcement portion 34, so that the gravity received by the cantilever beam 1 can be distributed to the first connection member 31 and the two second connection members 32, so as to reduce the shear force received by the first connection member 31.

[0042] Furthermore, in some embodiments, Figure 2 As shown, two second reinforcing parts 34 are provided, and the two second reinforcing parts 34 are arranged at intervals on the first connecting member 31, and each second reinforcing part 34 is connected to the cantilever beam 1 and the two second connecting members 32. The two second reinforcing parts 34 are provided to make the connection between the first connecting member 31 and the two second connecting members 32 more stable, and the second reinforcing part 34 connected to the bottom of the cantilever beam 1 can share more of the gravity on the cantilever beam 1.

[0043] In some embodiments, one of the second reinforcing parts 34 is tilted toward the direction close to the cantilever beam 1. Preferably, the second reinforcing part 34 connected to the bottom of the cantilever beam 1 is tilted, which can transfer the gravity exerted on the cantilever beam 1 to the structural column 2, thereby reducing the shear force exerted on the first connecting member 31.

[0044] There is no limitation on the connection method between the second connecting member 32 and the structural column 2, as long as the second connecting member 32 can share the force received by the first connecting member 31 and transfer it to the structural column 2. For example, in some embodiments, Figure 3 As shown, a welding stud 36 pre-embedded and extending into the structural column 2 is welded on the side of the second connecting member 32 facing the structural column 2. Compared with connecting the second connecting member 32 and the structural column 2 by inserting steel bars, the use of the welding stud 36 to connect avoids damage to the steel bars extending along the z direction in the structural column 2, thereby avoiding affecting the overall structural performance of the structural column 2.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
