Description

Technical Field

[0001] This utility model relates to the field of building structure technology, specifically to a cantilever beam rigid connection structure that can improve the safety performance of buildings. Background Technology

[0002] A cantilever beam is a beam that extends beyond a wall or supporting structure. The characteristic of a cantilever beam is that its ends are not directly supported by a wall or column, but rather cantilevered over a certain length. It is typically used to provide more space or support structures above. A rigid connection refers to a joint formed by a rigid connection between structural members. In construction, a rigid connection usually means that two members are connected together by welding, bolts (212), or other fixing methods, and relative rotation or displacement is not allowed at the connection point. Therefore, a rigid cantilever beam structure refers to a design where the cantilever beam and the supporting structure are rigidly connected.

[0003] Chinese Patent Publication No. CN219586929U discloses a rigid joint of a cantilever steel beam in a concrete structure, comprising a concrete beam and a cantilever beam. One end of the cantilever beam is cast inside the concrete beam. A reinforcing plate is fitted and fixed on the cantilever beam, located at the end of the cantilever beam or the end of the concrete beam. The concrete beam includes beam tie bars and stirrups. The beam tie bars are distributed on the outside of the cantilever beam, and the stirrups surround the beam tie bars. The reinforcing plate is welded to the beam tie bars. Stiffening ribs are welded to both sides of the reinforcing plate and are welded to the cantilever beam. This utility model improves the shear strength between the concrete beam and the cantilever beam by casting a cantilever beam inside the concrete beam and setting a reinforcing plate that is welded to both the concrete beam and the cantilever beam. At the same time, the welded stiffening ribs ensure the load-bearing capacity and stability of the cantilever beam.

[0004] The aforementioned patent mentions that this utility model improves the shear strength between the concrete beam and the cantilever beam by casting a cantilever beam inside the concrete beam and setting a reinforcing plate on the cantilever beam. However, since the reinforcement of the connection between the cantilever beam and the concrete beam mainly relies on components such as reinforcing plates and stiffening ribs, in terms of stress distribution, these components are difficult to distribute the stress more evenly, resulting in unclear stress concentration points and stress transmission paths. Under large loads, the structure is prone to damage due to excessive local stress. Therefore, we propose a cantilever beam rigid connection structure that can improve the building safety performance. Utility Model Content

[0005] To address the aforementioned issues, a cantilever rigid connection structure that improves building safety is provided. This structure utilizes a combined reinforcement mechanism in conjunction with a slotted hole mechanism to install with horizontal and vertical beams. This allows the entire combined reinforcement mechanism to work collaboratively as a whole when resisting shear forces, avoiding stress concentration. This solves the technical problem of structural damage caused by excessive local stress in cantilever rigid connection structures under large loads.

[0006] To address the problems of existing technologies, this utility model provides a cantilever beam rigid connection structure that can improve the safety performance of buildings. The structure includes a horizontal beam with a vertical beam positioned below it. The cantilever beam rigid connection structure also includes a composite reinforcement mechanism, a slotted mechanism, and a guide mechanism.

[0014] The advantages of this utility model compared to the prior art are:

[0015] 1.

[0025] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0026] See Figures 1-2 As shown, a cantilever beam rigid connection structure that can improve the safety performance of a building includes a horizontal beam 1, with a vertical beam 11 disposed on the lower side of the horizontal beam 1. The cantilever beam rigid connection structure also includes a composite reinforcement mechanism, a slotted mechanism, and a guiding mechanism. The horizontal beam 1 and the vertical beam 11 are provided with a composite reinforcement mechanism to enhance structural strength and optimize mechanical properties. The side of the horizontal beam 1 and the vertical beam 11 near the composite reinforcement mechanism is provided with a slotted mechanism to enhance the connection strength between the composite reinforcement mechanism and the horizontal beam 1, as well as between the composite reinforcement mechanism and the vertical beam 11. The composite reinforcement mechanism is provided with a guiding mechanism to assist in the positioning and welding of the composite reinforcement mechanism. The composite reinforcement mechanism includes a U-shaped reinforcement mechanism, a connecting mechanism, and a shear-resistant mechanism. The horizontal beam 1 is provided with a U-shaped reinforcement mechanism to constrain the concrete and enhance its shear resistance. The U-shaped reinforcement mechanism is provided with a connecting mechanism to enhance the connection stability of the U-shaped reinforcement mechanism. The vertical beam 11 is provided with a shear-resistant mechanism to improve the shear bearing capacity of the vertical beam 11 and enhance the overall structural integrity of the U-shaped reinforcement mechanism.

[0027] Specifically, the rigid cantilever beam structure mainly consists of horizontal beam 1, vertical beam 11, as well as a composite reinforcement mechanism, a slotted hole mechanism, and a guiding mechanism. The composite reinforcement mechanism, as a key component for enhancing structural strength and optimizing mechanical properties, is composed of a U-shaped reinforcement mechanism, a connecting mechanism, and a shear-resistant mechanism working in concert.

[0028] The U-shaped reinforcement structure is arranged inside the crossbeam 1 to effectively improve the shear resistance of the structure by confining the concrete. Under stress, concrete is prone to shear deformation, and the U-shaped reinforcement structure can limit the lateral deformation of the concrete, allowing the concrete to withstand shear forces more effectively.

[0029] The connecting mechanism is connected to the U-shaped rib mechanism, which enhances the connection stability of the U-shaped rib mechanism and ensures that the U-shaped rib mechanism will not shift or loosen during operation, thereby ensuring the stability of shear resistance.

[0030] The shear-resistant mechanism is set in the vertical beam 11, which can improve the shear bearing capacity of the vertical beam 11 itself, and enhance the structural integrity of the U-shaped reinforcement mechanism, so that the entire composite reinforcement mechanism forms a coordinated organic whole when resisting shear force.

[0031] The slotted mechanism is located on the side of the crossbeam 1 and the vertical beam 11 near the composite reinforcement mechanism. Its function is to enhance the connection between the composite reinforcement mechanism and the beam body and to optimize the stress distribution.

[0032] See Figures 1-4 , Figure 6 and Figure 7 As shown, the U-shaped reinforcement mechanism includes a first U-shaped stirrup 2, a second U-shaped stirrup 21, and a connecting ring 22; the first U-shaped stirrup 2 is disposed within the crossbeam 1; the second U-shaped stirrup 21 is disposed on the side of the vertical beam 11 away from the crossbeam 1; the connecting ring 22 is connected to the second U-shaped stirrup 21; the connecting mechanism includes a main reinforcement 23 and a secondary reinforcement 24; the main reinforcement 23 is disposed above the first U-shaped stirrup 2 and the second U-shaped stirrup 21; one end of the secondary reinforcement 24 is welded to the main reinforcement 23, and the other end of the secondary reinforcement 24 is disposed within the crossbeam 1; the shear-resistant mechanism includes a first shear-resistant reinforcement 25 and a second shear-resistant reinforcement 26; the first shear-resistant reinforcement 25 is disposed within the crossbeam 1; the second shear-resistant reinforcement 26 is disposed on the crossbeam 1 near the first shear-resistant reinforcement 25. On one side, the second shear reinforcement 26 is inserted into the connecting ring 22; the first shear reinforcement 25 is also provided with a transverse reinforcement 27 and a fixing ring 28; one end of the first shear reinforcement 25 is welded to the middle of the transverse reinforcement 27; the fixing ring 28 is welded to both ends of the transverse reinforcement 27 respectively, and the fixing ring 28 is sleeved with both ends of the second U-shaped stirrup 21; the slot mechanism includes a first reinforcement slot 29 and a second reinforcement slot 210; the first reinforcement slot 29 is opened on the side of the crossbeam 1 near the secondary reinforcement 24, and the first reinforcement slot 29 is used to cooperate with the secondary reinforcement 24 to be vertically inserted into the interior of the crossbeam 1; the second reinforcement slot 210 is opened on the side of the crossbeam 1 near the first U-shaped stirrup 2, and the second reinforcement slot 210 is used to cooperate with the first U-shaped stirrup 2 to be vertically inserted into the interior of the crossbeam 1.

[0033] Specifically, during the installation of the first U-shaped stirrup 2 and the second U-shaped stirrup 21, a first reinforcement groove 29 and a second reinforcement groove 210 are first opened on the crossbeam 1. The secondary reinforcement 24 is vertically inserted into the first reinforcement groove 29 and fixed. Then, the first U-shaped stirrup 2 is inserted into the second reinforcement groove 210 and fixed. After this, a guide mechanism is installed on the upper side of the first U-shaped stirrup 2 and the second U-shaped stirrup 21.

[0034] Next, the first shear reinforcement 25 is fixedly connected to the vertical beam 11. A second U-shaped stirrup 21 is selected, and it is welded through the fixing ring 28. Then, the main reinforcement 23 is passed through the guide mechanism, and the guide mechanisms of the remaining second U-shaped stirrups 21 are sequentially fitted onto the end of the main reinforcement 23 furthest from the horizontal beam 1. The guide mechanisms of the second U-shaped stirrups 21 are welded to the main reinforcement 23 at equal intervals. During this process, it is ensured that one end of the main reinforcement 23 is close to the secondary reinforcement 24. Then, the guide mechanisms of the main reinforcement 23 and the secondary reinforcement 24, and the main reinforcement 23 and the first U-shaped stirrup 2 are welded respectively.

[0035] After completing the above operations, the second shear reinforcement 26 is passed through the connecting ring 22 and fixed to the vertical beam 11. Then, the second shear reinforcement 26 is welded to the connecting ring 22.

[0036] When the structure is under load, the concrete undergoes lateral deformation. The first U-shaped stirrup 2 effectively restricts this deformation, thereby enhancing the shear resistance of the beam 1. The main reinforcement 23 connects the U-shaped reinforcement mechanism into a whole, improving the collaborative working ability between the components and enhancing the restraint effect on the concrete, thus increasing the shear strength of the entire structure and enabling more efficient force transmission between the U-shaped stirrups. The secondary reinforcement 24 can transfer the force borne by the main reinforcement 23 to the beam 1, enhancing the connection stability between the U-shaped reinforcement mechanism and the beam 1, ensuring that the U-shaped reinforcement mechanism can work collaboratively with the beam 1 during the stress process, avoiding displacement or detachment, and ensuring the reliability of the structure.

[0037] When the structure is subjected to shear force, the first shear reinforcement 25 can effectively share the shear force and enhance the shear resistance of the beam 1. The second shear reinforcement 26 is welded to the connecting ring 22, which further enhances and strengthens the shear resistance of the structure, while also enhancing the overall structural integrity of the U-shaped reinforcement mechanism, making the entire structure more stable when subjected to shear force.

[0038] The first reinforcing groove 29, in conjunction with the secondary reinforcing bar 24, is vertically inserted into the crossbeam 1, enhancing the anchorage force between the secondary reinforcing bar 24 and the crossbeam 1. This ensures that the secondary reinforcing bar 24 will not slip during force transmission, effectively improving the connection strength between the connecting mechanism and the crossbeam 1. The second reinforcing groove 210, in conjunction with the first U-shaped stirrup 2, is inserted into the crossbeam 1, making the connection between the first U-shaped stirrup 2 and the crossbeam 1 more stable. This optimizes the stress transmission path between the U-shaped reinforcing bar mechanism and the crossbeam 1, resulting in a more uniform stress distribution when the structure is under load, thereby improving the structure's load-bearing capacity and durability.

[0039] See Figure 5 As shown, the guiding mechanism includes a threaded groove 211, a bolt 212, and a collar 213; the threaded groove 211 is formed on the first U-shaped stirrup 2 and the second U-shaped stirrup 21; the bolt 212 is threadedly connected to the threaded groove 211; the collar 213 is rotatably mounted on the bolt 212 and is sleeved with the main reinforcement 23.

[0040] Specifically, when the guide mechanism is installed with the first U-shaped stirrup 2 and the second U-shaped stirrup 21, the bolt 212 is rotated and connected to the threaded groove 211. The bolt 212 and the threaded groove 211 are then threaded together, so that the bolts 212 of each guide mechanism are respectively bound together with the first U-shaped stirrup 2 and the second U-shaped stirrup 21 and welded together. When the main rib 23 is welded to the collar 213, the worker can rotate the collar 213 to facilitate the insertion of the main rib 23 and the collar 213, thus facilitating the welding of the main rib 23 and the collar 213, so that the first U-shaped stirrup 2 and the second U-shaped stirrup 21 can form a whole.

[0041] Working principle: When the combined reinforcement mechanism is installed with the horizontal beam 1 and the vertical beam 11, the combined reinforcement mechanism is installed together with the horizontal beam 1 and the vertical beam 11 through the slot mechanism, so that the stress can be more evenly distributed between the beam body and the combined reinforcement mechanism, avoiding stress concentration, improving the load-bearing capacity and durability of the structure, and the combined reinforcement mechanism can improve the welding accuracy through the guide mechanism, ensuring the overall performance of the combined reinforcement mechanism, thereby improving the quality and safety of the entire cantilever beam rigid connection structure.

[0042] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
