Description

Technical Field

[0001] This invention relates to a connection structure, specifically a high-load-bearing steel beam diagonal brace connection structure and its connection method, belonging to the field of support connection technology. Background Technology

[0002] With the increasing prevalence of high-rise buildings, modular prefabricated building technology has been vigorously promoted, and steel structure buildings, which combine the characteristics of green buildings and prefabricated buildings, have also developed rapidly. Currently, many high-rise buildings, especially super high-rise buildings, use steel structures for their main structure.

[0003] Most high-rise projects are characterized by high ceilings, short construction periods, large workloads, and numerous overlapping operations by various trades, resulting in significant safety hazards in the vertical space during construction. Traditionally, safety netting during the construction of high-rise steel structure main frames is primarily installed within the building's floors, neglecting the structural support and protection of the entire structure. Many safety accidents during the installation and construction of steel structure buildings are caused by the uncontrolled collapse of steel components. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: a high-load-bearing steel beam diagonal brace connection structure and its connection method, comprising a steel beam, two support frames fitted on the outer side of the steel beam, and mounting frames fixedly connected to the bottom of each of the two support frames. The support frames and mounting frames support the steel beam, preventing it from falling directly and ensuring the stability of the steel beam during construction. The steel beam has slots on both sides, and a locking box is provided on one side of each slot. The locking box installs the steel beam, preventing the tilted load-bearing steel beam from sliding, completely supporting and limiting the position of the steel beam, and fixing its position. A push rod is provided between the locking box and the support frame. The steel beam has a grouting groove and a drainage groove. Self-locking boxes are fixedly connected to both sides of the support frame. Each self-locking box contains a limit rod, a spring, and a sliding lock block. The self-locking structure, composed of the self-locking box, spring, and sliding lock block, cooperates with the self-locking slots on the steel beam. When the locking boxes fail to function, the steel beam is automatically limited and supported. Each support frame has two self-locking slots on both sides.

[0005] Preferably, the support frame has an installation groove, and one end of the snap-fit ​​box extends into the installation groove. Concrete is poured into the snap-fit ​​box through a grouting groove and a drainage groove. After the concrete solidifies, the snap-fit ​​box is completely fixed to the steel beam. The drainage groove is located between two snap-fit ​​boxes, and the grouting groove is located at the top of the steel beam. The bottom end of the grouting groove extends into the drainage groove, which improves the stability of the steel beam in the building.

[0006] Preferably, the snap-fit ​​box has multiple filling vertical rods fixedly connected inside, which increases the contact area between the concrete and the snap-fit ​​box. One end of the push rod is fixedly connected to the snap-fit ​​box, and the other end of the push rod passes through the snap-fit ​​box to completely fix the steel beam, the mounting frame and the steel beam together, ensuring the stability of the steel beam in the building. One end of the push rod is fixedly connected to a boss.

[0007] Preferably, one of the support frames has multiple circular slots, and each of the multiple circular slots is provided with a rod. One end of the rod is fixedly connected to another support frame, and the other end of the rod is fixedly connected to a transverse bolt. A mounting nut is threaded on the outside of the transverse bolt. After the rod passes through the circular slot, the mounting nut is rotated and fitted on the outside of the transverse bolt to install and fix the two support frames together.

[0008] Preferably, the mounting frame includes two supporting inclined plates, two connecting plates, and two reinforcing rods. The two connecting plates are fixedly connected between the two supporting inclined plates to form a triangular mounting frame with high stability. The two reinforcing rods are fixedly connected between the two mounting frames and one of the connecting plates. The mounting frame supports the support frame and ensures the stability of the support frame in supporting and limiting the steel beam.

[0009] Preferably, four connecting rods are provided between the two mounting brackets. One of the mounting brackets has four T-slots on one side, and the other mounting bracket has four through holes on one side. Pulling the connecting rods away from the T-slots and through holes removes the fixing between the two mounting brackets. One end of each of the four connecting rods is fixedly connected to a short bolt. The short bolts are threaded with a first nut on the outside to facilitate the recycling of the support frame and the mounting bracket.

[0010] Preferably, the spring is fixedly connected between the sliding lock block and the self-locking box. There are two springs. The sliding lock block pushed by the spring enters the self-locking groove. The sliding lock block is locked between the steel beam and the self-locking box, limiting the movement of the steel beam and locking the position of the steel beam.

[0011] Preferably, the limiting rod is rotatably connected to one side of the sliding lock block, and a threaded tube is fixedly sleeved on the outside of the limiting rod. Rotating the limiting rod causes the threaded tube to rotate and connect with the self-locking box. The threaded tube is threaded to the self-locking box. A hexagonal groove is opened on one side of the limiting rod to thread the limiting rod and the self-locking box together, thereby limiting the sliding lock block and preventing the sliding lock block from affecting the transportation of the support frame.

[0012] Preferably, the two self-locking boxes are distributed one above the other on both sides of the support frame, and the self-locking grooves are opened one above the other inside the steel beam. The self-locking grooves are aligned with the self-locking boxes. At this time, the sliding lock block pushed by the spring enters the self-locking groove and limits the movement of the steel beam.

[0013] A method for connecting a high-load-bearing steel beam diagonal brace includes the following steps:

[0014] Step 1: After placing the two support frames on the outside of the steel beam, support the steel beam to prevent it from falling directly.

[0015] Step 2: Control the push rod to move the clamping box. The clamping box is locked between the steel beam and the support frame to limit the steel beam and prevent the load-bearing steel beam from tilting and sliding.

[0016] Step 3: When the steel beam slides accidentally, the spring pushes the sliding lock block into the self-locking groove when the self-locking box aligns with the self-locking groove, thus limiting the movement of the steel beam.

[0017] Step 4: Rotate the first nut to remove the fixing between the two mounting brackets; use a tool to pull the boss and pull the snap-fit ​​box out of the slot opened in the steel beam to complete the disassembly and recycling of the support frame;

[0018] Step 5: Pour concrete into the clamp box through the grouting tank and the diversion tank. After the concrete solidifies, it will completely fix the clamp box to the steel beam, thereby improving the stability of the steel beam in the building.

[0019] This invention provides a high-load-bearing steel beam diagonal brace support connection structure and its connection method, which has the following beneficial effects:

[0020] 1. The connection structure and method of the high-load-bearing steel beam diagonal brace support: the push rod pushes the snap-fit ​​box to move, and one end of the moving snap-fit ​​box is inserted into the snap-fit ​​groove. At this time, the snap-fit ​​box is stuck between the steel beam and the support frame. The snap-fit ​​box supports the steel beam to prevent the tilted load-bearing steel beam from sliding, completely supporting and limiting the position of the steel beam, fixing the position of the steel beam, avoiding accidents caused by the steel beam falling and sliding, and ensuring the safety of the staff.

[0021] 2. The high-load-bearing steel beam diagonal brace connection structure and its connection method are as follows: After the steel beam is installed in the preset position, two support frames are placed on the outside of the steel beam and then fixed together. Finally, the mounting frame is fixed to the building ground so that the support frames and mounting frame support the steel beam, preventing the steel beam from falling directly and ensuring the stability of the steel beam construction.

[0022] 3. The connection structure and method of this high-load-bearing steel beam diagonal brace support: When the steel beam slides unexpectedly despite being supported by two support frames, the spring pushes the sliding locking block into the self-locking groove after the self-locking box aligns with the self-locking groove on the steel beam. This locks the sliding locking block between the steel beam and the self-locking box, limiting the steel beam and preventing it from falling and causing an accident. The self-locking structure, composed of the self-locking box, spring, and sliding locking block, works in conjunction with the self-locking groove on the steel beam to automatically limit and support the steel beam when the locking box fails to function, ensuring safety during steel beam installation.

[0023] 4. The high-load-bearing steel beam diagonal brace connection structure and its connection method involve injecting concrete into the clamping box through grouting grooves and drainage grooves. After the concrete solidifies, it completely fixes the clamping box to the steel beam. The clamping box is also fixedly connected with multiple filling vertical rods, which increase the contact area between the concrete and the clamping box, ensuring the firmness of the clamping box and the steel beam. This completely fixes the steel beam, the mounting frame, and the steel beam together, ensuring the stability of the steel beam in the building.

[0024] 5. The connection structure and method of this high-load-bearing steel beam diagonal brace support: By rotating the first nut away from the outside of the short bolt, the fixing between the connecting rod and the support frame can be removed. At this time, the connecting rod can be pulled away from the T-slot and through hole, thus removing the fixing between the two mounting brackets. This allows for quick removal of the fixing between the two mounting brackets, completing the disassembly of the mounting brackets and facilitating the recycling of the support frame and mounting brackets. Rotating the limiting rod causes the threaded tube to rotate and connect with the self-locking box. By fixing the limiting rod to the self-locking box threadedly, the sliding locking block is limited, keeping it inside the self-locking box. This prevents the sliding locking block from affecting the transportation of the support frame and ensures the convenience of reusing the support frame. Attached Figure Description

[0035] This invention provides a high-load steel beam diagonal brace connection structure and its connection method.

[0036] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 The system includes a steel beam 1, with two support frames 2 fitted on the outer side of the steel beam 1. Each support frame 2 has a mounting bracket 3 fixedly connected to its bottom. The steel beam 1 has slots 12 on both sides, and a snap-fit ​​box 15 is provided on one side of each slot 12. A push rod 17 is provided between the snap-fit ​​box 15 and the support frame 2. The steel beam 1 has a grouting groove 13 and a drainage groove 29. Each support frame 2 has a self-locking box 19 fixedly connected to both sides. The self-locking box 19 has a limit rod 22, a spring 21 and a sliding lock block 20 inside. Each support frame 2 has two self-locking grooves 14 on both sides.

[0037] Specifically, after the steel beam 1 is installed in the preset position, two support frames 2 are placed on the outside of the steel beam 1 and then fixed together. Finally, the mounting frame 3 is fixed to the building ground so that the support frames 2 and the mounting frame 3 support the steel beam 1, preventing the steel beam 1 from falling directly and ensuring the stability of the construction of the steel beam 1.

[0038] Then, force is applied to the push rod 17, causing the push rod 17 to push the snap-fit ​​box 15 to move. One end of the moving snap-fit ​​box 15 is inserted into the snap-fit ​​slot 12. At this time, the snap-fit ​​box 15 is stuck between the steel beam 1 and the support frame 2. The steel beam 1 is installed through the snap-fit ​​box 15 to prevent the load-bearing steel beam 1 from tilting and sliding. The steel beam 1 is completely supported and limited, and the position of the steel beam 1 is fixed to prevent the steel beam 1 from falling and sliding, thus ensuring the safety of the staff.

[0039] Furthermore, self-locking boxes 19 are fixedly connected to both sides of the support frame 2. Inside the self-locking boxes 19, a sliding locking block 20 is installed via a spring 21. When the steel beam 1, supported by the two support frames 2, still slides accidentally, the spring 21 pushes the sliding locking block 20 into the self-locking groove 14 on the steel beam 1 after the self-locking box 19 aligns with it. This locks the steel beam 1 between the steel beam 1 and the self-locking box 19, limiting its movement and preventing it from falling and causing an accident. The self-locking structure, composed of the self-locking box 19, spring 21, and sliding locking block 20, works in conjunction with the self-locking groove 14 on the steel beam 1. When the locking box 15 fails to function, it automatically limits and supports the steel beam 1, ensuring safety during installation.

[0040] Additionally, to enhance the stability of the steel beam 1, a grouting groove 13 is provided at the top of the steel beam 1, and a drainage channel 29 is positioned between the two clamping boxes 15. Concrete can be poured into the clamping boxes 15 through the grouting groove 13 and the drainage channel 29. After the concrete solidifies, the clamping boxes 15 are completely fixed to the steel beam 1, thus permanently securing the steel beam 1, the mounting frame 3, and the steel beam 1 together, ensuring the stability of the steel beam 1 in the building.

[0041] Please refer to it again. Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 8 The support frame 2 has an installation groove 26. One end of the snap-fit ​​box 15 extends into the installation groove 26. The drainage channel 29 is set between two snap-fit ​​boxes 15. The grouting channel 13 is opened at the top of the steel beam 1. The bottom end of the grouting channel 13 extends into the drainage channel 29. Multiple filling vertical rods 16 are fixedly connected inside the snap-fit ​​box 15. One end of the push rod 17 is fixedly connected to the snap-fit ​​box 15. The other end of the push rod 17 passes through the snap-fit ​​box 15. A boss 18 is fixedly connected to one end of the push rod 17. One of the support frames 2 has multiple circular grooves 27. Each of the multiple circular grooves 27 is provided with a plug rod 24. One end of the plug rod 24 is fixedly connected to another support frame 2. The other end of the plug rod 24 is fixedly connected to a transverse bolt 25. An installation nut is threaded on the outside of the transverse bolt 25.

[0042] Specifically, a boss 18 is fixedly connected to one end of the push rod 17 that passes through the support frame 2. By applying force to the boss 18, the boss 18 exerts a moving force on the push rod 17. The moving push rod 17 pushes the snap-fit ​​box 15 into the slot 12. At this time, an interference fit structure is formed between the snap-fit ​​box 15 and the steel beam 1. A relatively large force needs to be applied to the snap-fit ​​box 15 to pull it out of the slot 12. Furthermore, there is a large space between the boss 18 and the support frame 2. Workers can use tools to pull the boss 18 and pull the snap-fit ​​box 15 out of the slot 12 opened in the steel beam 1, allowing the support frame 2 to be recycled and reused.

[0043] After rotating and removing the mounting nut on the outer thread of the transverse bolt 25, pull the two support frames 2 in opposite directions to make the multiple inserts 24 leave the multiple circular grooves 27. The fixation between the two support frames 2 is removed, and the two support frames 2 can be disassembled to complete the recycling of the support frames 2 and ensure the convenience of reusing the support frames 2.

[0044] Similarly, after inserting the rod 24 through the circular groove 27, the mounting nut is rotated and fitted on the outside of the transverse bolt 25 to fix the two support frames 2 together.

[0045] Concrete can be poured into the snap-fit ​​box 15 through the grouting tank 13 and the diversion tank 29. After the concrete solidifies, the snap-fit ​​box 15 is completely fixed to the steel beam 1. The snap-fit ​​box 15 is also fixedly connected with multiple filling vertical rods 16. The multiple filling vertical rods 16 increase the contact area between the concrete and the snap-fit ​​box 15, ensuring the firmness of the snap-fit ​​box 15 and the steel beam 1. Thus, the steel beam 1, the mounting frame 3 and the steel beam 1 are completely fixed together, ensuring the firmness of the steel beam 1 in the building.

[0046] Please refer to it again. Figure 1 and Figure 3 The mounting bracket 3 includes two supporting inclined plates 4, two connecting plates 5, and two reinforcing rods 6. The two connecting plates 5 are fixedly connected between the two supporting inclined plates 4, and the two reinforcing rods 6 are fixedly connected between the two mounting brackets 3 and one of the connecting plates 5. Four connecting rods 7 are provided between the two mounting brackets 3. One side of one mounting bracket 3 has four T-shaped grooves 8, and the other side of the mounting bracket 3 has four through holes 11. One end of each of the four connecting rods 7 is fixedly connected to a short bolt 9, and a first nut 10 is threaded on the outside of the short bolt 9.

[0047] Specifically, a triangular mounting frame 3 with high stability is formed by two supporting inclined plates 4, two connecting plates 5, and two reinforcing rods 6. The mounting frame 3 supports the support frame 2, ensuring the stability of the support frame 2 in supporting and limiting the steel beam 1.

[0048] Rotate the first nut 10 away from the outside of the short bolt 9 to remove the fixation between the connecting rod 7 and the support frame 2. At this time, the connecting rod 7 can be pulled away from the T-slot 8 and the through hole 11 to remove the fixation between the two mounting brackets 3. The fixation between the two mounting brackets 3 can be removed quickly, and the mounting brackets 3 can be disassembled, making it convenient to recycle the support frame 2 and the mounting brackets 3.

[0049] Please refer to it again. Figure 1 , Figure 2 , Figure 5 , Figure 7 and Figure 9 Spring 21 is fixedly connected between sliding lock block 20 and self-locking box 19. There are two springs 21. Limiting rod 22 is rotatably connected to one side of sliding lock block 20. Threaded tube 30 is fixedly sleeved on the outside of limiting rod 22. Threaded tube 30 is threadedly connected to self-locking box 19. Hexagonal groove 23 is opened on one side of limiting rod 22. Two self-locking boxes 19 are distributed on both sides of support frame 2, one above the other. Self-locking groove 14 is opened inside steel beam 1, one above the other.

[0050] Specifically, when the steel beam 1 slides between the two support frames 2, the self-locking groove 14 on the steel beam 1 slides towards the self-locking box 19, and the two self-locking grooves 14 are staggered, one above the other. Therefore, when the upper self-locking groove 14 aligns with the upper self-locking box 19, the lower self-locking groove 14 aligns with the lower self-locking box 19. At this time, the sliding locking block 20 pushed by the spring 21 enters the self-locking groove 14. At this time, part of the sliding locking block 20 is located inside the self-locking box 19, and the other part of the sliding locking block 20 is located in the self-locking groove 14 on the steel beam 1. The sliding locking block 20 is locked between the steel beam 1 and the self-locking box 19, limiting the movement of the steel beam 1 and locking its position, ensuring that the steel beam 1 is stably supported and limited.

[0051] After the support frame 2 is separated from the steel beam 1 and disassembled, the sliding locking block 20 is pushed back into the self-locking box 19. Then, an operator uses an external hex wrench to insert into the hexagonal slot 23 of the limiting rod 22, rotating the limiting rod 22 to rotate the threaded tube 30 and thread it into the self-locking box 19. By fixing the limiting rod 22 to the self-locking box 19, the sliding locking block 20 is limited, ensuring it is contained within the self-locking box 19. This prevents the sliding locking block 20 from interfering with the transportation of the support frame 2 and ensures the ease of reuse of the support frame 2.

[0052] A method for connecting a high-load-bearing steel beam diagonal brace includes the following steps:

[0053] Step 1: After installing the two support frames 2 on the outside of the steel beam 1, support the steel beam 1 to prevent it from falling directly; support and limit the steel beam 1 to reduce accidents during construction and reduce the danger to workers.

[0054] Step 2: Control the push rod 17 to move the clamping box 15. The clamping box 15 is clamped between the steel beam 1 and the support frame 2 to limit the steel beam 1 and prevent the load-bearing steel beam 1 from tilting and sliding. By limiting the support on both sides of the steel beam 1 through the two clamping boxes 15, the support of the steel beam 1 is completed, which facilitates the construction of the steel beam 1 and improves the safety of the workers around the steel beam 1.

[0055] Step 3: When steel beam 1 slides accidentally, when the self-locking box 19 aligns with the self-locking groove 14, the spring 21 pushes the sliding locking block 20 into the self-locking groove 14 to limit the steel beam 1. The self-locking box 19, spring 21 and sliding locking block 20 form a self-locking structure to ensure the stability of the steel beam 1 during installation. When the locking box 15 fails to function, it automatically limits and supports the steel beam 1, improving the safety of steel beam 1 during installation.

[0056] Step 4: Rotate the first nut 10 to remove the fixing between the two mounting brackets 3; use a tool to pull the boss 18 to pull the snap-fit ​​box 15 out of the slot 12 opened in the steel beam 1, and complete the disassembly and recycling of the support frame 2; the detachable design of the support frame 2 makes it easy to reuse the support frame 2, reducing the cost input in the construction process of the steel beam 1.

[0057] Step 5: Concrete is poured into the clamping box 15 through the grouting tank 13 and the drainage tank 29. After the concrete solidifies, the clamping box 15 is completely fixed to the steel beam 1, improving the stability of the steel beam 1 in the building. By replacing Step 4 with Step 5, the usage method of the support frame 2 can be selected according to the specific location of the steel beam 1, ensuring the function of the steel beam 1 in the building.
