Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a prefabricated inclined support node steel frame structure. Background Technology

[0002] A steel frame with diagonal bracing is a lateral force resisting structure that forms a geometrically invariant system by setting diagonal bracing members at column nodes. Its core feature is that the rigid connection nodes and diagonal bracing work together to significantly improve the structural stiffness and stability, effectively resist horizontal loads, and control lateral displacement. This structure combines the advantages of steel frames and bracing systems and is widely used in large-span or high-rise buildings.

[0003] In the existing inclined support steel frame structure, the columns and beams are mainly installed using I-beams. After the columns and beams of the main building are installed, inclined support columns are installed between the columns and beams on both sides. The inclined support columns, columns and beams form a fixed frame, thereby realizing the installation of the inclined support steel frame.

[0004] When installing existing inclined steel frame structures, the columns, beams, and inclined support columns are mostly rigidly connected. This not only results in insufficient installation and docking accuracy and inaccurate node positioning, but also means that when subjected to wind loads, earthquakes, or equipment vibrations, the vibration energy is directly transmitted to the main structure without an effective buffering and dissipation mechanism. After long-term use, the connection nodes are prone to stress concentration, leading to problems such as bolt loosening and weld fatigue. The ease of use and installation needs to be improved.

[0008] As a preferred embodiment of the prefabricated inclined support node steel frame structure of the present invention, the rotating support has a limiting groove inside, and the limiting groove inside the rotating support can cooperate with the bottom of the inclined support column.

[0009] As a preferred embodiment of the prefabricated inclined support node steel frame structure of the present invention, there are two fixing components, which are respectively arranged on both sides of the column. The outer surface of the rotating block is provided with a U-shaped locking plate. The two ends of the two adjacent U-shaped locking plates are inserted with fixing bolts. The fixing bolts pass through the inside of the U-shaped locking plates and are engaged with locking nuts. The outer surface of the rotating block is provided with a groove that cooperates with the U-shaped locking plate.

[0010] As a preferred embodiment of the prefabricated inclined support node steel frame structure of the present invention, the fixing block has a through hole inside that matches the fixing rod. The fixing rod passes through the inside of the fixing block and is fixedly connected to the L-shaped rotating plate. The bottom of the L-shaped rotating plate has a groove. The fixing rod is fixedly installed inside the bottom groove of the L-shaped rotating plate. The fixing block abuts against the inner wall of the bottom groove of the L-shaped rotating plate.

[0011] As a preferred embodiment of the prefabricated inclined support node steel frame structure of the present invention, both ends of the curved plate are straight segments, the middle part of the curved plate is an arc segment, and the interior of the movable socket and the interior of the plug-in seat are provided with slots that cooperate with the straight segments of the curved plate.

[0016] This invention provides a prefabricated inclined bracing node steel frame structure. It has the following advantages: 1. The curved plate and the buffer components work together. When the beam vibrates, the curved plate can elastically deform to absorb and dissipate energy, reducing the direct impact on the inclined support column and the main structure, and improving the structural durability and safety. Under extreme conditions, the curved plate bends to dissipate energy, and the buffer cylinders on both sides expand outward to form an arch support, ensuring structural stability. At the same time, the limiting groove of the fixing component, the T-shaped sliding block and limiting strip of the installation component and other structures realize the precise docking of each component and improve the installation accuracy.

[0017] 2. The curved plate is installed by inserting its bottom into the plug socket and its top into the movable socket. This allows the curved plate to be installed without locking it, ensuring that it can effectively absorb vibration. The fixing component provides support for the bottom of the curved plate and also provides auxiliary positioning support for the bottom of the inclined support column, ensuring installation accuracy and structural stability.

[0018] 3. By installing the curved plate through the plug-in socket and the movable socket, the inclined support and the curved plate work together to provide stiffness during mild vibration. Furthermore, neither the plug-in socket nor the movable socket locks the curved plate, allowing the curved plate to act as an energy-dissipating element to reduce vibration transmission. At the same time, the prefabricated design facilitates the inspection and replacement of the curved plate, enabling convenient and quick replacement of the curved plate to restore structural function and facilitate maintenance.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Example

[0033] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the first embodiment of the present invention, which provides a prefabricated inclined bracing node steel frame structure, including: Column 1, with a crossbeam 2 fixedly connected to the top of column 1, and inclined support columns 3 fixedly connected between both sides of column 1 and the lower surface of crossbeam 2. Fixing component 4 is disposed on the side of column 1. Fixing component 4 includes an abutting plate 401 that abuts against the outer surface of column 1. A plug-in seat 404 is fixedly installed on the side of abutting plate 401 away from column 1. Mounting component 6 is disposed on the outer surface of crossbeam 2. Mounting component 6 includes a fixing plate 606 abutting against the lower surface of crossbeam 2. Two fixing blocks 607 are fixedly installed on both sides of fixing plate 606. Fixing rods 602 are interspersed inside the two fixing blocks 607 on the same side. L-shaped rotating plates 601 are fixedly connected to both ends of fixing rods 602. A movable socket 603 is provided on the lower surface of fixing plate 606. A curved plate 7 is inserted between the plug socket 404 and the mobile socket 603.

[0034] like Figure 5 and Figure 6 In this embodiment, both ends of the curved plate 7 are straight segments, the middle part of the curved plate 7 is an arc segment, and the interior of the movable socket 603 and the interior of the plug-in base 404 are provided with slots that cooperate with the straight segments of the curved plate 7. The bottom straight section of the curved plate 7 is inserted into the inside of the plug-in seat 404, so that the bottom of the curved plate 7 is fixedly supported by the plug-in seat 404. The top straight section of the curved plate 7 is inserted into the inside of the movable socket 603. The movable socket 603 is set so that the crossbeam 2 can drive the curved plate 7 to bend when it vibrates, thereby absorbing and dissipating vibration energy. Both ends of the curved plate 7 are plug-in installed, which ensures that the curved plate 7 can deform elastically and absorb the vibration of the beam 2 caused by external factors.

[0035] like Figure 5 , Figure 6 , Figure 7 , Figure 8 as well as Figure 9 In this embodiment, a T-shaped sliding block 604 is fixedly connected to the upper surface of the movable socket 603, and a limiting groove that cooperates with the T-shaped sliding block 604 is opened on the lower surface of the fixing plate 606. A limiting strip 609 is fixedly connected to the top of the inner wall of the bottom groove of the L-shaped rotating plate 601 away from the column 1. Movable blocks 608 are fixedly connected to both sides of the upper surface of the movable socket 603. A through hole that cooperates with the fixing rod 602 is opened inside the movable block 608. The movable block 608 moves on the outer surface of the fixing rod 602 through the through hole. A limiting groove that cooperates with the limiting strip 609 is opened on the top side of the movable block 608 away from the column 1. After the top straight section of the curved plate 7 is engaged with the movable socket 603, the movable socket 603 is moved toward the side away from the column 1 by the elasticity of the curved plate 7 itself. The linear movement of the movable socket 603 is limited by the cooperation of the T-shaped sliding block 604 and the limiting slide groove. When the movable socket 603 moves, it causes the movable block 608 to move on the outer surface of the fixed rod 602, so that the limiting groove on the outer surface of the movable block 608 cooperates with the limiting strip 609 on the inner wall of the groove at the bottom of the L-shaped rotating plate 601, thereby locking the L-shaped rotating plate 601 so that it cannot be rotated and opened, thus ensuring that the L-shaped rotating plates 601 on both sides can be locked with the crossbeam 2.

[0036] like Figure 5 , Figure 6 as well as Figure 7 In this embodiment, a fixing baffle 605 is fixedly installed on the lower surface of the crossbeam 2 on the side of the fixing plate 606 away from the column 1; By setting the fixed baffle 605, support is provided for the fixed plate 606, preventing the fixed plate 606 from moving excessively on the outer surface of the crossbeam under the elastic force of the curved plate 7, ensuring that the curved plate 7 maintains a bent state. Through the elastic force provided by the curved plate 7 in the bent state, the crossbeam 2 is supported. Thus, under slight vibration, the crossbeam 2 is supported by the curved plate 7 and the inclined support column 3.

[0037] Furthermore, the bottom end of the curved plate 7 is inserted into the interior of the plug-in seat 404, and the top end of the curved plate 7 is inserted into the interior of the movable socket 603. The plug-in seat 404 provides support for the bottom of the curved plate 7. The movable socket 603 drives the fixed plate 606 to abut against the lower surface of the crossbeam 2. Then, the L-shaped rotating plate 601 is rotated to a vertical state, so that the fixed plate 606 is installed on the lower surface of the crossbeam 2. Under the elastic force of the curved plate 7 itself, the movable socket 603 drives the moving block 608 to cooperate with the limiting strip 609, thereby locking the L-shaped rotating plate 601 so that it cannot rotate, ensuring that the top of the curved plate 7 is locked and cannot be opened. Neither the movable socket 603 nor the plug-in seat 404 fixes the curved plate, thereby ensuring that the curved plate can deform freely and absorb vibration. At the same time, through the setting of the installation component 6, the curved plate 7 can be easily and quickly disassembled. Thus, the curved plate 7, as an energy-dissipating element, reduces vibration transmission, and the curved plate can be easily and quickly replaced, thereby restoring the structural function and facilitating maintenance. Example

[0038] Reference Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. Rotating blocks 402 are hinged to both sides of the top and bottom of the abutment plate 401. Rotating supports 403 are fixedly installed on the top of the two upper rotating blocks 402.

[0039] like Figure 1 as well as Figure 2 In this embodiment, the rotating block 402 has a slot on the side near the column 1, and a through hole is provided inside the rotating block 402. After the rotating block 402 rotates to the vertical position, it is fixedly connected to the column 1 by high-strength bolts. The rotating block 402 is fixed to the outer surface of the column 1 by high-strength bolts to achieve the fixed abutment plate 401.

[0040] like Figure 5 , Figure 6 , Figure 7 , Figure 8 as well as Figure 9 In this embodiment, a limiting groove is provided inside the rotating support 403. The limiting groove inside the rotating support 403 can cooperate with the bottom of the inclined support column 3. Mounting plates are provided at the bottom and top of the inclined support column 3. The mounting plates are fixedly connected to the outer surface of the column 1 and the outer surface of the beam 2 by high-strength bolts. The limiting groove inside the rotating support 403 can provide auxiliary support for the mounting plate at the bottom of the inclined support column 3.

[0041] like Figure 5 , Figure 6 as well as Figure 7In this embodiment, there are two fixing components 4. The two fixing components 4 are respectively set on both sides of the column 1. The outer surface of the rotating block 402 is provided with a U-shaped locking plate 406. The two ends of the two adjacent U-shaped locking plates 406 are provided with fixing bolts 405. The fixing bolts 405 pass through the inside of the U-shaped locking plate 406 and are engaged with locking nuts 407. The outer surface of the rotating block 402 is provided with a groove that cooperates with the U-shaped locking plate 406. There are two fixing components 4 in total. Both sides of the column 1 are provided with abutment plates 401. The top and bottom of the two abutment plates 401 are hinged with two rotating blocks 402. The outer surfaces of the four upper rotating blocks 402 and the four lower rotating blocks 402 are provided with two U-shaped locking plates 406. The two adjacent U-shaped locking plates 406 are further locked by fixing bolts 405 and locking nuts 407 engaging with the grooves on the outer surface of the rotating blocks 402, thereby ensuring stable installation.

[0042] Furthermore, the abutment plate 401 is abutted against the outer surface of the column 1. At this time, the rotating block 402 is in a horizontal state. After the abutment plate 401 is abutted, the rotating block 402 is rotated to a vertical state, which in turn drives the rotating support 403 to a vertical state. This allows the limiting groove inside the rotating support 403 to engage with the bottom of the inclined support column 3. Then, the rotating block 402 and the column 1 are fixed with high-strength bolts, thereby fixing the rotating block 402. By fixing the abutment plate 401, the insertion seat 404 can stably support the bottom of the curved plate 7, while the rotating support 403 provides auxiliary support to the bottom of the inclined support column 3, ensuring the stability of the inclined support column 3. Example

[0043] Reference Figure 1 , Figure 10 and Figure 11 This is the third embodiment of the present invention, which is based on the previous embodiment. The buffer component 5 is disposed on the outer surface of the inclined support column 3. The buffer component 5 includes a U-shaped insert plate 501 inserted into the outer surface of the inclined support column 3. Insertion discs 508 are fixedly installed on both sides of the U-shaped insert plate 501. A connecting block 506 is inserted into the inside of the insertion disc 508. A connecting plate 502 is fixedly connected to the end of the connecting block 506 away from the insertion disc 508. A buffer cylinder 509 is movably installed on the end of the connecting plate 502 away from the U-shaped insert plate 501 through a bearing.

[0044] like Figure 1 , Figure 10 and Figure 11In this embodiment, the outer surface of the inclined support column 3 is provided with a slot that matches the U-shaped insert plate 501, the outer surface of the insert disc 508 is provided with an insertion port that matches the connecting block 506, the insertion port is inserted with an insertion block 503, the top of the insertion block 503 is fixedly connected with an arc plate 505, both ends of the arc plate 505 are movably installed with threaded rods 504, the inside of the insert disc 508 is fixedly connected with an internal threaded cylinder 507, and the threaded rods 504 are threadedly connected to the internal threaded cylinder 507. The slot and the U-shaped insert 501 are engaged to ensure that the U-shaped insert 501 will not slip off the outer surface of the inclined support column 3, and the slot and the U-shaped insert 501 are interference fit to ensure the stability of the U-shaped insert 501. The top outer surface of the threaded rod 504 is threaded with a hexagonal nut. By rotating the hexagonal nut, the hexagonal nut presses against the outer surface of the arc plate 505, thereby locking the threaded rod 504 so that it cannot rotate, ensuring a stable fit between the threaded rod 504 and the inner threaded cylinder 507.

[0045] like Figure 1 , Figure 10 and Figure 11 In this embodiment, the outer surface of the connecting block 506 is provided with an annular groove, and the inner wall of the insertion port on the outer surface of the insertion disc 508 is provided with a limiting protrusion that cooperates with the annular groove. The engagement of the annular groove and the limiting protrusion allows the connecting plate 502 to be inserted into the insertion disc 508, enabling the limiting connecting block 506 to rotate stably. The bottom of the plug-in block 503 has an arc-shaped groove that matches the connecting block 506, ensuring that the plug-in block 503 can stably lock the connecting block 506 so as not to detach from the plug-in disc 508, and does not affect the rotation of the connecting block 506.

[0046] Furthermore, by inserting the U-shaped insert plate 501 into the groove on the outer surface of the inclined support column 3, and then placing the buffer cylinder 509 below the inclined support column 3, the connecting plate 502 drives the connecting block 506 to rotate above the inclined support column 3, thereby inserting it into the insert disc 508. Then, the insert block 503 is inserted into the insert disc 508. Then, by rotating the threaded rod 504, the threaded rod 504 is driven to rotate and engage with the inner threaded cylinder 507, thereby locking the arc plate 505. Then, the hexagonal nut on the top outer surface of the threaded rod 504 is rotated to lock the threaded rod 504. Finally, the installation of the buffer assembly 5 is completed. Through the setting of the buffer assembly 5, the curved plate can bend significantly under extreme conditions to dissipate energy, causing the buffer cylinders on both sides to expand outward. The curved plate abuts against the outer surface of the inclined support column through the buffer cylinder, forming an arched support, further ensuring structural stability.

[0047] Working Principle: During the installation of the inclined support node steel frame structure, the existing engineering installation steps are followed to install the column 1 and beam 2, as well as the inclined support column 3. At this point, the existing inclined support column 3 frame structure is installed. Then, the abutment plate 401 is abutted against the outer surface of the column 1. At this time, the rotating block 402 is in a horizontal state. After the abutment plate 401 is in contact with the column 1, the rotating block 402 is rotated, causing it to rotate to a vertical state. This, in turn, causes the rotating support 403 to rotate to a vertical state, allowing the limiting groove inside the rotating support 403 to engage with the bottom of the inclined support column 3. Then, high-strength bolts are used to fix the rotating block 402 to the column 1, thus fixing the rotating block 402 and the rotating support 403. 3. Auxiliary support is provided at the bottom of the inclined support column 3. Then, the buffer assembly 5 is installed on the outer surface of the inclined support column 3. The U-shaped insert plate 501 is inserted into the groove on the outer surface of the inclined support column 3. Then, the buffer cylinder 509 is placed below the inclined support column 3. The connecting plate 502 drives the connecting block 506 to rotate above the inclined support column 3, thereby inserting it into the insertion disc 508. Then, the insertion block 503 is inserted into the insertion disc 508. Then, by rotating the threaded rod 504, the threaded rod 504 is driven to rotate and engage with the inner threaded cylinder 507, thereby locking the arc plate 505. Then, the hexagonal nut on the top outer surface of the threaded rod 504 is rotated to lock the threaded rod 504. Finally, the installation of the buffer assembly 5 is completed. 5. After installation, begin installing component 6. During installation, insert the bottom of the curved plate 7 into the insertion socket 404 on the outer surface of the abutment plate 401. Then, insert the straight part at the top of the curved plate 7 into the movable socket 603. Next, lift the movable socket 603 upwards, causing the upper surface of the fixed plate 606 to abut against the lower surface of the crossbeam 2. As the movable socket 603 moves upwards, it causes the curved plate 7 to bend, thus abutting against the two buffer cylinders 509 below the inclined support column 3. The two buffer cylinders 509 rotate through the cooperation of the connecting plate 502 and the connecting block 506, rotating to both sides. After the fixed plate 606 abuts against the lower surface of the crossbeam 2, rotate the L-shaped rotating plates 601 on both sides to a vertical state, thereby achieving passage. The L-shaped rotating plate 601 is locked in place, and then the movable socket 603 is released. Under its own elastic force, the curved plate 7 moves the movable socket 603 and the fixed plate 606, causing the fixed plate 606 to abut against the outer surface of the fixed baffle 605, preventing it from moving further. Meanwhile, under the elastic force of the curved plate 7, and through the cooperation of the T-shaped sliding block 604 and the limiting groove on the lower surface of the fixed plate 606, the movable block 603 moves on the outer surface of the fixed rod 602. The groove on the outer surface of the movable block 608 cooperates with the limiting strip 609, thereby locking the L-shaped rotating plate 601 and preventing it from rotating open, ensuring that the fixed plate 606 is locked onto the crossbeam 2.Finally, the installation of the steel frame structure for the overall diagonal support stage is completed. The rotating support 403 of the fixing component 4 provides support and fixation for the bottom of the diagonal support column 3 and the bottom of the curved plate 7. The installation component 6 provides installation and fixation for the top of the curved plate 7, and the elasticity of the curved plate 7 itself ensures that the installation component 6 will not detach. The buffer component 5 provides a buffer between the curved plate 7 and the diagonal support column 3, preventing the protrusion of the curved plate 7 from directly contacting the outer surface of the diagonal support column 3, thus affecting the elastic deformation of the curved plate 7. When the beam 2 is subjected to lateral load, the load is transferred to the curved plate 7 through the installation component 6, forcing the pre-bent curved plate 7 to undergo further elastic or elastoplastic deformation. This process absorbs energy through the deformation of the curved plate 7 itself and provides auxiliary energy dissipation through the buffer cylinder 509 of the buffer component 5. The deformation of the curved plate 7 diverts some of the force to the fixing component 4 and then to the column 1, thereby reducing stress concentration in the diagonal support column 3 and its connecting nodes. If the load is extremely high, the middle part of the curved plate 7 will make full contact with the buffer cylinder 509, further optimizing the force flow path. The overall structure will then enter a state of high-intensity energy dissipation and enhanced load-bearing capacity, ultimately completing the use of the inclined support node steel frame structure.
