A buckling-restrained brace device

Abstract

This utility model provides a buckling restraint support device, including a buckling restraint main body and further comprising: an adjustment structure disposed at both ends of the buckling restraint main body; and a pushing structure disposed within the adjustment structure. By rotating the handle block, the second fixed plate and the square connecting frame are moved, increasing the distance between the first fixed plate and the second fixed plate. This facilitates better adjustment of the length of the buckling restraint support device according to the support requirements, making the buckling restraint support device flexible in use. By tightening the fixing bolts, the fixing bolts are threaded into the corresponding thread grooves, fixing the fixing blocks in place. This prevents the rotating block from rotating, which could cause the threaded rod to rotate, loosening the adjustment structure and affecting the support effect of the buckling restraint support device.

Description

Technical Field

[0001] This utility model relates to the field of buckling-restrained bracing technology, and in particular to a buckling-restrained bracing device. Background Technology

[0002] Buckling-restrained bracing is a novel type of bracing consisting of a core steel core, an outer restraint sleeve, and an unbonded insulating material. The core steel core, as the primary load-bearing component, provides lateral stiffness during the elastic phase and dissipates seismic energy through hysteretic deformation after yielding. The outer restraint sleeve prevents buckling of the steel core through a composite structure of reinforced concrete or square steel tubing. The unbonded insulating material uses materials such as rubber, polyethylene, and silicone to eliminate friction, with silicone offering the most ideal insulating effect.

[0003] However, the length of typical buckling-restrained braces is not adjustable, limiting their overall usability and making it difficult to adapt their length to different support ranges. This results in a lack of flexibility in their use. Therefore, how to effectively adjust the length of buckling-restrained braces according to the specific support requirements is a crucial issue that needs to be addressed in the design of buckling-restrained braces. Utility Model Content

[0004] This invention provides a buckling restraint support device to solve the problem that the length of the buckling restraint support device cannot be adjusted.

[0005] This utility model solves the above-mentioned technical problems through the following technical solutions:

[0006] This utility model provides a buckling restraint support device, including a buckling restraint support body, and further comprising:

[0007] An adjustment structure is provided at both ends of the anti-buckling support body;

[0008] A pushing structure is provided, which is disposed within an adjusting structure. The pushing structure rotates to drive the adjusting structure to move and adjust.

[0009] Preferably, the adjustment structure includes a first fixed plate, a square connecting frame, a second fixed plate, a first sliding frame, and a second sliding frame. The first fixed plate is fixedly connected to the side walls at both ends of the anti-buckling support body. The first sliding frame is fixedly connected to the side wall on the other side of the first fixed plate. The square connecting frame is slidably connected to the first sliding frame. The second sliding frame is slidably connected to the other end of the square connecting frame. The second fixed plate is fixedly connected to the other end of the second sliding frame.

[0010] In this technical solution, the connecting plate rotates to push the fixed plate two and the square connecting frame to move. The fixed plate two drives the sliding frame two to slide out from the square connecting frame. The square connecting frame moves, causing the sliding frame one to slide out from the square connecting frame, and the distance between the fixed plate one and the fixed plate two increases.

[0011] Preferably, two mounting plates are fixedly connected to the side wall of the second fixing plate, and circular mounting holes are provided on the side walls of the two mounting plates.

[0012] In this technical solution, the buckling brace body can be installed through the mounting plate and the mounting holes on the mounting plate.

[0013] Preferably, threaded grooves are provided at equal intervals in the center of one side wall of the square connecting frame, and the threaded grooves are distributed in a ring.

[0014] Preferably, the length and width of the first fixing plate and the second fixing plate are consistent with the length and width of the square connecting frame.

[0015] Preferably, the pushing structure includes a handle block, a rotating block, threaded rods, a connecting block, a first fixing block, and a fixing bolt. The rotating block is rotatably connected to the side walls on opposite sides of the square connecting frame. Two threaded rods are fixedly connected to the side walls on opposite sides of the rotating block. A connecting block is fixedly connected between the two threaded rods. A first fixing block and a handle block are fixedly connected to the side wall of the rotating block. A fixing bolt is threadedly connected to the side wall of the first fixing block.

[0016] In this technical solution, rotating the handle block causes the rotating block to rotate, which in turn causes the threaded rod to rotate, which in turn causes the connecting block to rotate, and the connecting block causes the threaded rod on the other side to rotate, so that the two threaded rods rotate synchronously.

[0017] Preferably, the rotating block is positioned at the exact center of the annularly distributed threaded grooves.

[0018] Preferably, the size of the fixing bolt is configured to match the threaded groove.

[0019] In this technical solution, the fixing bolt is threaded into the corresponding thread groove. The fixing block is fixed by the fixing bolt. After the fixing block is fixed, the rotation of the rotating block is fixed and restricted, thereby preventing the rotating block from rotating and causing the threaded rod to rotate, which would loosen the adjustment structure and affect the support effect of the buckling brace.

[0020] Preferably, the threads on the two threaded rods on both sides of the connecting block are opposite to each other.

[0021] In this technical solution, the two threaded rods rotate synchronously, driving the two moving frames to move, so that the two moving frames can move closer to each other or further away from each other.

[0022] Preferably, the pushing structure includes a movable frame, a connecting plate, and a second fixed block. The movable frame is threadedly connected to a threaded rod. One end of the connecting plate is rotatably connected to the sidewalls at both ends of the movable frame. The other end of the connecting plate is rotatably connected to the second fixed block. The second fixed block is fixedly connected to the sidewalls of the first fixed plate and the first fixed plate, respectively.

[0023] In this technical solution, the two threaded rods rotate synchronously, driving the two movable frames to move. The two movable frames move closer to each other, causing the connecting plates on both sides to rotate. The connecting plates then push the fixed plate and the square connecting frame to move.

[0024] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0025] The positive and progressive effects of this utility model are as follows:

[0026] 1. By rotating the handle block, the two threaded rods rotate synchronously. The threaded rods drive the two movable frames to move. The two movable frames move closer to each other, causing the connecting plates on both sides to rotate. The connecting plates then push the second fixed plate and the square connecting frame to move. The distance between the first fixed plate and the second fixed plate increases, thereby increasing the overall length of the buckling brace. This makes it easier to adjust the length of the buckling brace according to the support needs, thus making the buckling brace flexible in use.

[0027] 2. By tightening the fixing bolts, the fixing bolt threads are connected into the corresponding thread grooves, and the fixing block is fixed in place by the fixing bolts. After the fixing block is fixed, the rotation of the rotating block is fixed and restricted, which helps to prevent the rotating block from rotating and causing the threaded rod to rotate, which would loosen the adjustment structure and affect the support effect of the buckling brace.

[0034] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments described herein.

[0035] like Figures 1-4 As shown, a buckling restraint brace includes a buckling restraint brace body 1, and further includes:

[0036] Adjustment structure 2, wherein the adjustment structure 2 is disposed at both ends of the anti-buckling support body 1;

[0037] A pushing structure 5 is disposed within an adjusting structure 2. The pushing structure 5 rotates to push the adjusting structure 2 to move and adjust.

[0038] The adjustment structure 2 includes a first fixed plate 201, a square connecting frame 202, a second fixed plate 203, a first sliding frame 204, and a second sliding frame 205. The first fixed plate 201 is fixedly connected to the side walls at both ends of the anti-buckling support body 1. The first sliding frame 204 is fixedly connected to the side wall on the other side of the first fixed plate 201. The square connecting frame 202 is slidably connected to the first sliding frame 204. The second sliding frame 205 is slidably connected to the other end of the square connecting frame 202. The second fixed plate 203 is fixedly connected to the other end of the second sliding frame 205.

[0039] The connecting plate 512 rotates and pushes the fixed plate 203 and the square connecting frame 202 to move. The fixed plate 203 drives the sliding frame 205 to slide out from the square connecting frame 202. The square connecting frame 202 moves, so that the sliding frame 204 slides out from the square connecting frame 202, and the distance between the fixed plate 201 and the fixed plate 203 increases.

[0040] Two mounting plates 3 are fixedly connected to the side wall of the fixing plate 203, and circular mounting holes are provided on the side wall of the two mounting plates 3.

[0041] The buckling brace body 1 can be installed through the mounting plate 3 and the mounting holes on the mounting plate 3.

[0042] The square connecting frame 202 has threaded grooves 4 evenly spaced in the middle of one side wall, and the threaded grooves 4 are distributed in a ring.

[0043] The length and width of the fixing plate 1 201 and fixing plate 203 are consistent with the length and width of the square connecting frame 202.

[0044] The pushing structure 5 includes a handle block 501, a rotating block 502, a threaded rod 503, a connecting block 504, a fixing block 505, and a fixing bolt 506. The rotating block 502 is rotatably connected to the side walls on opposite sides of the square connecting frame 202. Two threaded rods 503 are fixedly connected to the side walls on opposite sides of the rotating block 502. A connecting block 504 is fixedly connected between the two threaded rods 503. A fixing block 505 and a handle block 501 are fixedly connected to the side wall of the rotating block 502. A fixing bolt 506 is threadedly connected to the side wall of the fixing block 505.

[0045] Rotate handle block 501, which drives rotating block 502 to rotate. Rotating block 502 drives threaded rod 503 to rotate. Threaded rod 503 drives connecting block 504 to rotate. Connecting block 504 drives threaded rod 503 on the other side to rotate, so that the two threaded rods 503 rotate synchronously.

[0046] The rotating block 502 is located at the very center of the annularly distributed threaded grooves 4.

[0047] The size of the fixing bolt 506 is set to match the threaded groove 4.

[0048] The fixing bolt 506 is threaded into the corresponding threaded groove 4. The fixing block 505 is fixed by the fixing bolt 506. After the fixing block 505 is fixed, the rotation of the rotating block 502 is fixed and restricted, thereby preventing the rotating block 502 from rotating and causing the threaded rod 503 to rotate, which would cause the adjusting structure 2 to loosen and affect the support effect of the buckling brace.

[0049] The threads on the two threaded rods 503 on both sides of the connecting block 504 are opposite to each other.

[0050] The two threaded rods 503 rotate synchronously, driving the two movable frames 511 to move, so that the two movable frames 511 can move closer to each other or further away from each other.

[0051] The pushing structure 5 includes a movable frame 511, a connecting plate 512, and a second fixing block 513. The movable frame 511 is threadedly connected to the threaded rod 503. One end of the connecting plate 512 is rotatably connected to the side walls at both ends of the movable frame 511. The other end of the connecting plate 512 is rotatably connected to the second fixing block 513. The second fixing block 513 is fixedly connected to the first fixing plate 201 and the side wall of the fixing plate, respectively.

[0052] The two threaded rods 503 rotate synchronously, driving the two movable frames 511 to move. The two movable frames 511 move closer to each other, driving the connecting plates 512 on both sides to rotate. The connecting plates 512 then push the fixed plate 203 and the square connecting frame 202 to move.

[0053] In use, the buckling brace main body 1 can be installed through the mounting plate 3 and the mounting holes on the mounting plate 3. When adjusting the overall length of the buckling brace device, the handle block 501 can be rotated. The handle block 501 drives the rotating block 502 to rotate, the rotating block 502 drives the threaded rod 503 to rotate, the threaded rod 503 drives the connecting block 504 to rotate, and the connecting block 504 drives the threaded rod 503 on the other side to rotate. The two threaded rods 503 rotate synchronously, driving the two moving frames 511 to move. The two moving frames 511 move closer to each other, driving the connecting blocks on both sides... When the connecting plate 512 rotates, it pushes the second fixed plate 203 and the square connecting frame 202 to move. The second fixed plate 203 drives the second sliding frame 205 to slide out from the square connecting frame 202. The square connecting frame 202 moves, causing the first sliding frame 204 to slide out from the square connecting frame 202. The distance between the first fixed plate 201 and the second fixed plate 203 increases, thereby increasing the overall length of the buckling brace. This makes it easier to adjust the length of the buckling brace according to the support needs, thus making the buckling brace flexible in use.

[0054] After the buckling brace is adjusted, tighten the fixing bolt 506 to thread the fixing bolt 506 into the corresponding threaded groove 4. Fixing block 505 is fixed by fixing bolt 506. After fixing block 505 is fixed, the rotation of rotating block 502 is fixed and restricted, thereby preventing rotating block 502 from rotating and causing threaded rod 503 to rotate, causing adjustment structure 2 to loosen and affecting the support effect of buckling brace.

The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
