Description

Technical Field

[0001] This utility model relates to the field of BRB buckling restraint brace technology, specifically to a convenient BRB buckling restraint brace connection node connection device. Background Technology

[0002] The buckling-restrained brace (BRB) connection node is a key force-transfer component connecting the buckling-restrained brace (BRB) to the main structure (such as steel beams and columns, or concrete frames). It is the core connection point that ensures the BRB can bear forces normally in the structure and play its role in seismic energy dissipation. Through specific mechanical design, it achieves reliable force transfer between the BRB and the main structure, adapts to structural deformation requirements, and provides a convenient interface for construction and installation.

[0003] In the existing technology, when installing the BRB buckling restraint brace and the connection node, the column is only lifted by the gantry wheel to tilt and align. Because the gantry wheel lacks a rigid support positioning structure, the column is easily shaken by external forces (such as wind force and operation collisions), resulting in large node alignment deviations, repeated adjustments that are time-consuming, and the column is prone to collision with the main structure or other components during the shaking process, posing safety hazards of component damage and personnel injury. Utility Model Content

[0004] The purpose of this utility model is to provide a convenient BRB buckling restraint brace connection node connection device to solve the problems mentioned in the background art, where the BRB buckling restraint brace and connection node are installed by relying solely on the lifting wheel to tilt and align the column. Due to the lack of rigid support positioning of the lifting wheel, the column is easily shaken by external forces, resulting in large node alignment deviations, time-consuming repeated adjustments, and the column is prone to collision with other components during shaking, posing safety hazards such as component damage and personnel injury.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a convenient BRB buckling restraint support connection node connection device, including a base plate and a fixed plate connected to the top of the base plate, a fixed block connected to the front side of the top of the fixed plate, a lead screw rotatably connected to the rear end of the fixed block, a motor connected to the rear end of the fixed plate, the output end of the motor connected to the lead screw, a movable block threadedly connected to the outer end of the lead screw, the movable block slidably connected to the fixed plate, connecting plates connected to the front sides of the left and right ends of the fixed plate, an inclined plate connected between the two connecting plates, auxiliary blocks connected to the top left and right sides of the inclined plate, multiple anti-slip plates connected to the top of the inclined plate, a connecting block connected to the bottom of the inclined plate, a rotating plate rotatably connected between the connecting block and the movable block, a support assembly connected to the rear end of the base plate, the motor drives the lead screw to rotate on the fixed block, causing the movable block to slide on the fixed plate, pushing the rotating plate to rotate on the connecting block and the movable block, causing the inclined plate to rotate on the connecting plate, fitting against the external support column for support, and installing the support column and the connection node.

[0006] According to the preferred embodiment of this technical solution, the support component includes four movable wheels that are rotatably installed on the left and right sides of the base plate. A support plate is connected to the rear end of the base plate, and expansion blocks are connected to the top left and right sides of the support plate.

[0007] In a preferred embodiment of this technical solution, the outer end of the expansion block is rotatably connected to a rotating block, and the rotating block has an internal movable groove.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5This utility model provides an embodiment of a convenient BRB buckling restraint support connection node connection device, including a base plate 1 and a fixed plate 21 connected to the top of the base plate 1. A fixed block 22 is connected to the front side of the top of the fixed plate 21. A lead screw 23 is rotatably connected to the rear end of the fixed block 22. A motor 24 is connected to the rear end of the fixed plate 21. The output end of the motor 24 is connected to the lead screw 23. A moving block 25 is threadedly connected to the outer end of the lead screw 23. The moving block 25 is slidably connected to the fixed plate 21. Connecting plates 26 are connected to the front sides of the left and right ends of the fixed plate 21. An inclined plate 27 is connected between the two connecting plates 26. Auxiliary blocks 28 are connected to the left and right sides of the top of the inclined plate 27. Multiple anti-slip plates 29 are connected to the top of the inclined plate 27. A connecting block 211 is connected to the bottom of the inclined plate 27. A rotating plate 210 is rotatably connected between the connecting block 211 and the moving block 25. A support assembly is connected to the rear end of the base plate 1. The motor 24 drives the lead screw 23 on the fixed block 22. The rotation causes the movable block 25 to slide on the fixed plate 21, pushing the rotating plate 210 to rotate on the connecting block 211 and the movable block 25, causing the inclined plate 27 to rotate on the connecting plate 26 and fit against the external support column for support. This allows the support column and the connecting node to be installed. By setting up the fixed plate 21, fixed block 22, lead screw 23, motor 24, anti-slip plate 29, connecting block 211, rotating plate 210 and other components in coordination, the auxiliary installation effect of the support column and the connecting node is achieved. The motor 24 drives the lead screw 23 to rotate and drive the movable block 25 to slide. The rotating plate 210 pushes the inclined plate 27 to rotate around the connecting plate 26, accurately adjusting the tilt angle to adapt to the installation requirements of the support column. The anti-slip plate 29 on the top of the inclined plate 27 increases the friction, and the auxiliary block 28 limits the offset to prevent deviation, stably supporting the support column and preventing shaking. The support components enhance the overall stability of the device, and work together to achieve safe lifting of the support column, precise angle control and node alignment assistance, improving the convenience and safety of installation.

[0022] Please see Figure 2-5 A further solution based on this embodiment is as follows: the support component includes four movable wheels 31 rotatably mounted on the left and right sides of the base plate 1. The rear end of the base plate 1 is connected to a support plate 32, and the top left and right sides of the support plate 32 are connected to extension blocks 33. The four movable wheels 31 enable the flexible movement of the entire device, which facilitates the quick adjustment of the device's working position according to the location of the connection nodes. The support plate 32 and the extension blocks 33 provide an installation foundation for the subsequent support structure, thus expanding the support adjustment range of the device.

[0023] Please see Figure 1-5 A further solution based on this embodiment is as follows: the outer end of the expansion block 33 is rotatably connected to a rotating block 34, and the interior of the rotating block 34 is provided with a movable groove 35. The rotating block 34 can rotate around the expansion block 33 to flexibly adjust the support angle to adapt to different installation scenarios. The movable groove 35 provides sliding space for the movable block 36 and reserves a structural foundation for fine adjustment of the support position.

[0024] Please see Figure 1-5 A further solution based on this embodiment is as follows: a movable block 36 is slidably connected inside the movable groove 35, a threaded rod 37 is rotatably connected to the rear end of the movable block 36, a rotating ring 38 is rotatably connected to the end of the rotating block 34 away from the expansion block 33, the rotating ring 38 is threadedly connected to the threaded rod 37, and a connecting buckle 39 is rotatably connected to the end of the threaded rod 37 away from the rotating ring 38. Rotating the rotating ring 38 drives the threaded rod 37 to extend and retract through the threaded transmission, so that the movable block 36 slides in the movable groove 35, realizing linear adjustment of the support position of the connecting buckle 39, accurately adapting to the installation requirements of nodes at different distances, and improving support flexibility.

[0025] Please see Figure 1-5 A further solution based on this embodiment is as follows: the internal thread of the connecting buckle 39 is connected to a screw 310, and the internal part of the connecting buckle 39 is provided with a pre-embedded component. The pre-embedded component includes a support rod 311 movably connected inside the connecting buckle 39. The bottom of the support rod 311 is connected to a mounting plate 312. The screw 310 can fasten the connecting buckle 39 and the support rod 311 to ensure a stable connection of the support structure. The pre-embedded component is fixed near the node by the mounting plate 312 to provide a reliable fixed support point for the device and enhance the overall support rigidity.

[0026] Please see Figure 1-5 A further solution based on this embodiment is as follows: mounting holes 313 are provided on the top left and right sides of the mounting plate 312. The mounting plate 312 is pre-embedded in the position close to the connection node. The mounting holes 313 facilitate the secure pre-embedding and fixing of the mounting plate 312 with bolts, so that the support rod 311 forms a stable connection with the foundation structure, providing solid force support for the device and preventing the device from shifting during operation.

[0027] Please see Figure 1-5 A further solution based on this embodiment is as follows: the base plate 1 is pushed to the connection node position by the moving wheel 31, and the connecting buckle 39 is attached to the support rod 311. The screw 310 is rotated to limit the support rod 311. The rotating ring 38 drives the threaded rod 37 to rotate so that the movable block 36 slides in the movable groove 35. The support position is adjusted according to the specific situation. The whole operation process realizes the complete operation closed loop of the device from moving and positioning to precise fixing. The moving wheel 31 quickly puts the device into position, the screw 310 limits the connection to ensure stability, and the rotating ring 38 adjusts the support position to adapt to the device, which greatly improves the installation adaptability and support reliability of the device in different scenarios.

[0028] Working principle: First, the mounting plate 312 of the pre-embedded component is fixed to a preset position near the connection node using bolts through the mounting holes 313. Alternatively, the mounting plate 312 can be pre-embedded to ensure a stable support point between the support rod 311 and the foundation structure. The entire device is pushed to the connection node using the four movable wheels 31 at the bottom of the base plate 1. During this process, the flexibility of the movable wheels 31 allows for quick adjustment of the working position. Then, the connecting buckle 39 is attached to the support rod 311, and the screw 310 is turned to tighten the connecting buckle 39, achieving rigid fixation between the device and the pre-embedded component. The support angle is adjusted by rotating the rotating block 34 according to the site space. Then, the rotating ring 38 is rotated to drive the threaded rod 37 to extend and retract via threaded transmission, causing the movable block 36 to slide within the movable groove 35, precisely adjusting the support position of the connecting buckle 39 to ensure the overall device is compatible with the working environment. Blocks 32 and 33 provide structural support for the aforementioned adjustments. The motor 24 drives the lead screw 23 to rotate on the fixed block 22, causing the moving block 25 to slide along the fixed plate 21. The moving block 25 pushes the inclined plate 27 to rotate around the connecting plate 26 through the rotating plate 210 until the inclined plate 27 is in contact with the support column. The anti-slip plate 29 on the top of the inclined plate 27 increases the friction, and the auxiliary block 28 restricts the lateral displacement of the support column. The two work together to stably support the support column and prevent shaking during installation. Under the stable support of the inclined plate 27, the support column maintains the preset tilt angle. At this time, the support column can be safely and conveniently connected to the connecting node for installation. The entire device achieves precise angle control through mechanical transmission and ensures support stability through multiple fixing structures. The entire process does not require manual hoisting and alignment, greatly improving installation efficiency and safety.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
