Description

Technical Field

[0001] The present invention relates to the technical field of building beams and columns, and particularly relates to an anti-seismic connection structure for steel structure beam-column joints. Background Art

[0002] For example, a building beam-column connection structure for seismic reinforcement with the Chinese patent publication number: CN116446541B. During the installation of the side building beam, air is inflated into the airbag by moving a distance to increase the friction between the splicing plate and the main building column, thereby achieving the anti-seismic effect.

[0003] However, the problems existing in the above method are as follows: Vibration is multi-directional and uncontrollable. If vibration occurs in the up and down direction, the support rod may move upward. If the upward movement is relatively large, the extrusion and locking of the side building beam may be released, thus failing to achieve the anti-seismic effect.

[0004] In the conventional technology, the main building column is usually locked by single-direction extrusion, and this method is also prone to instability of the connection structure due to vibrations in different directions, unable to achieve the firmness between the main building beam and the side building beam, and naturally unable to achieve a good anti-seismic effect. In view of the problem that the existing beam-column joint connection structure cannot achieve a good anti-seismic effect, a steel structure beam-column joint anti-seismic connection structure is proposed. Summary of the Invention

[0005] In order to solve the above problems, the embodiment of the present invention provides a steel structure beam-column joint anti-seismic connection structure, which solves the problem that the beam-column joint connection structure in the background art cannot achieve a good anti-seismic effect.

[0006] The embodiment of the present invention specifically adopts the following technical solutions to achieve the above purpose: A steel structure beam-column joint anti-seismic connection structure includes a main building column and a side building beam. A connecting piece is provided on the outer side of the main building column, and the connecting piece is used to enhance the anti-seismic performance between the side building beam and the main building column. The connecting piece is connected to the outer side of the main building column by bolts. A reinforcing disc is provided on the outer side of the connecting piece by a fixing method. An insertion opening for installing the side building beam is formed on the connecting piece below the reinforcing disc. A reinforcing mechanism is provided below the reinforcing disc. A plurality of reinforcing arc plates are provided on the inner side of the connecting piece. When the side building beam is connected to the main building column, the reinforcing arc plates are made to closely adhere to the outer surface of the main building column through the reinforcing mechanism. A fastening plate is inserted into the side wall of the connecting piece near the insertion opening, and the fastening plate is used to enhance the fastening between the side building beam and the main building column when the side building beam enters the insertion opening.

[0007] Preferably, the connecting member is composed of two connecting arc plates, the connecting arc plates are arranged in a semi-circular manner, the radian of the connecting arc plates fits the radian of the main building column, and a plurality of bolt holes with apertures corresponding to the bolts are formed in the connecting member. The connecting member can be initially installed on the outer side of the main building column through the bolts.

[0008] Preferably, the reinforcing mechanism includes a sliding frame slidably connected below the reinforcing disc. A main driving block is slidably connected in the sliding frame. A fixing spring is provided between the main driving block and the sliding frame. The main driving block is arranged in a right trapezoidal manner, and its inclined surface faces the moving direction when the side building beam is installed. An active rack is provided on the sliding frame. A driving shaft is rotatably connected to the reinforcing disc. A first gear and a second gear are respectively fixedly connected to the top end and the bottom end of the driving shaft. The active rack and the first gear are mutually adapted.

[0009] Preferably, a reinforcing ring is rotatably connected to the upper end surface of the reinforcing disc. A transmission tooth ring is provided inside the reinforcing ring. The transmission tooth ring and the second gear are mutually adapted.

[0010] Preferably, a plurality of storage grooves are provided inside the connecting member. The storage grooves are connected to the reinforcing arc plates through telescopic rods. The moving direction of the reinforcing arc plates faces the center of the connecting member. The radian of the reinforcing arc plates corresponds to the radian of the main building column. A moving shaft is rotatably connected to the connecting member. A moving cylinder is provided on the side of the reinforcing arc plate opposite to the main building column. Internal threads are provided inside the moving cylinder. External threads are provided on the outer side of the moving shaft. The external threads and the internal threads are threadedly connected. One end of the moving shaft away from the reinforcing arc plate is fixedly connected with a transmission gear. A fixed tooth ring is provided on the top of the reinforcing ring. The transmission gear and the fixed tooth ring are meshed and connected.

[0011] Preferably, friction lines are provided on the side of the reinforcing arc plate opposite to the main building column.

[0012] Preferably, an installation frame body is provided outside the insertion port. The installation frame body plays a guiding role when the side building beam is installed.

[0013] The beneficial effects of the embodiments of the present invention are as follows: 1. Through the provided reinforcing arc plates in this solution, when the side building beam is connected to the main building column through the insertion opening, under the pushing action of the side building beam, the sliding frame can move a certain distance. This distance of movement will cause the second gear to rotate, and then drive the reinforcing ring to rotate. Thus, under the action of the transmission gear, the moving shaft rotates, and under the drive of the thread, the reinforcing arc plate is pressed against the main building column. In this method, the connection between the connecting piece and the main building column has fixing methods such as rotation and threads, and vibrations in one direction or multiple directions will not cause the reinforcing arc plate to move, thus playing a good anti-seismic role.

[0014] 2. Through the provided fastening plates in this solution, when the side building beam extends into the installation frame body, under the pushing force of its side wall, the fastening plates can move simultaneously towards the main building column. And the fastening plates are connected to the connecting piece through the installation frame body, which can also increase the stability between the connecting piece and the main building column.

[0015] 3. Through the provided installation frame body in this solution, when installing the side building beam, it can play a guiding role and can adjust the installation angle between the side building beam and the main building column, facilitating the determination of the installation angles of the main building column and the side building beam by workers during installation.

[0018] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0019] Embodiment 1 See the attached Figure 1 - attached Figure 8 A seismic connection structure for steel structure beam-column joints, including a main building column 1 and a side building beam 7. A connector 3 is provided outside the main building column 1, and the connector 3 is used to enhance the seismic resistance between the side building beam 7 and the main building column 1; Refer to the attached Figure 2 The connector 3 is composed of two connecting arc plates. The connecting arc plates are arranged in a semi-circular manner. The joints of the two connecting arc plates are connected by buckles. The radian of the connecting arc plate fits the radian of the main building column 1. By setting it in this way, the connector 3 can wrap the whole at the same height of the main building column 1, increasing the contact area between the two, and can increase the friction between the two to a certain extent, thereby improving the stability between the two.

[0020] A plurality of bolt holes 2 corresponding to the bolts 5 are provided on the connector 3. The connector 3 can be initially installed outside the main building column 1 through the bolts 5. When installing the connector 3 outside the main building column 1, the bolts 5 can initially relatively fix the connector 3 and the main building column 1, facilitating the subsequent connection between the side building beam 7 and the main building column 1. This method is a common existing means, and no excessive description will be made for the specific implementation.

[0021] Embodiment 2 In this embodiment, when the side building beam 7 is installed between the main building column 1, a plurality of reinforcement arc plates 8 can be relatively fixed to the main building column 1.

[0022] Specifically: The connecting member 3 is connected to the outside of the main building column 1 by bolts 5. A reinforcing disc 4 is provided on the outside of the connecting member 3 in a fixed manner. An insertion opening 15 for installing the side building beam 7 is formed in the connecting member 3 below the reinforcing disc 4. A reinforcing mechanism is provided below the reinforcing disc 4. A plurality of reinforcing arc plates 8 are provided inside the connecting member 3. When the side building beam 7 is connected to the main building column 1, the reinforcing arc plates 8 are in close contact with the outer surface of the main building column 1 through the reinforcing mechanism. Refer to the appendix Figure 5 and the appendix Figure 6 As shown, the reinforcing mechanism includes a sliding frame 17 slidably connected below the reinforcing disc 4. A main driving block 18 is slidably connected inside the sliding frame 17. A fixing spring 19 is provided between the main driving block 18 and the sliding frame 17. The main driving block 18 is arranged in a right trapezoid manner, and its inclined surface faces the moving direction when the side building beam 7 is installed. When the side building beam 7 moves into the insertion opening 15, the side building beam 7 will contact the inclined surface of the main driving block 18. At this time, the fixing spring 19 will not be compressed yet. When the sliding frame 17 moves to the maximum position, the fixing spring 19 will be compressed.

[0023] A driving rack 20 is provided on the sliding frame 17. A driving shaft 23 is rotatably connected to the reinforcing disc 4. A first gear 21 and a second gear 22 are respectively fixedly connected to the top and bottom ends of the driving shaft 23. Among them, the driving rack 20 and the first gear 21 are mutually adapted.

[0024] When the above-mentioned sliding frame 17 moves, the first gear 21 is rotated under the action of the driving rack 20. It should be noted that when the sliding frame 17 moves to the maximum distance, the driving rack 20 will be disengaged from the first gear 21 at this time. This is to ensure that when other side building beams 7 are installed subsequently, the first gear 21 is prevented from driving the sliding frame 17 to move, thus avoiding the situation of movement interference. And the driving rack 20 is not engaged with the first gear 21 in the initial state either. This setting is also to avoid affecting the initial position of other sliding frames 17 when other side building beams 7 are installed. Only when the sliding frame 17 moves, the driving rack 20 plays a role in driving the rotation of the first gear 21.

[0025] A reinforcing ring 13 is rotatably connected to the upper end surface of the reinforcing disc 4. A transmission gear ring 24 is provided inside the reinforcing ring 13. The transmission gear ring 24 and the second gear 22 are mutually adapted.

[0026] When the first gear 21 rotates as described above, the second gear 22 will be driven to rotate through the driving shaft 23. When the second gear 22 rotates, it will be engaged with the transmission gear ring 24 for transmission, thereby driving the entire reinforcing ring 13 to rotate.

[0027] One end of the moving shaft 9 away from the reinforcement arc plate 8 is fixedly connected with a transmission gear 11. A fixed gear ring 14 is provided at the top of the reinforcement ring 13. The transmission gear 11 is meshed with the fixed gear ring 14.

[0028] When the reinforcement ring 13 rotates, it will drive the transmission gear 11 to rotate through the fixed gear ring 14.

[0029] A moving shaft 9 is rotatably connected to the connecting member 3. A moving cylinder 10 is provided on the side of the reinforcement arc plate 8 opposite to the main building column 1. Internal threads are provided inside the moving cylinder 10, and external threads 12 are provided on the outside of the moving shaft 9. The external threads 12 are in threaded connection with the internal threads.

[0030] When the transmission gear 11 rotates as described above, it will cause the moving shaft 9 to rotate, and then under the cooperation of the internal threads and the external threads 12, the reinforcement arc plate 8 will move towards the main building column 1. After the installation of multiple side building beams 7 is completed, the moving distances of multiple reinforcement arc plates 8 reach the maximum. At this time, the degree of tightness between the reinforcement arc plate 8 and the main building column 1 reaches the maximum.

[0031] And this connection method is driven by threads. This transmission method will not cause the reinforcement arc plate 8 to move due to shaking in the up, down, left, or right directions. It ensures the relative stability of the whole.

[0032] A plurality of storage grooves 6 are provided inside the connecting member 3. The storage grooves 6 are provided to make the contact area between the inner wall of the connecting member 3 and the inner wall of the main building column 1 as large as possible. The reinforcement arc plate 8 is connected to the inside of the storage groove 6 through a telescopic rod. The moving direction of the reinforcement arc plate 8 is directly opposite to the center of the connecting member 3. The arc of the reinforcement arc plate 8 corresponds to the arc of the main building column 1; A friction pattern is provided on the side of the reinforcement arc plate 8 opposite to the main building column 1. Through the corresponding arcs and the friction patterns provided on the reinforcement arc plate 8, the contact between the reinforcement arc plate 8 and the main building column 1 is closer, the stability is stronger, and its seismic resistance ability is also stronger.

[0033] Embodiment 3 This embodiment is a preferred solution, and its function is the same as that of the above embodiment, which can increase the stability between the connecting member 3 and the main building column 1 when the side building beam 7 is installed.

[0034] Specifically, referring to the attached Figure 8 , A fastening plate 27 is inserted on the side wall of the connecting member 3 close to the insertion port 15. The fastening plate 27 is used to strengthen the fastening between the side building beam 7 and the main building column 1 when the side building beam 7 enters the insertion port 15.

[0035] An installation frame 16 is provided on the outer side of the insertion port 15. The installation frame 16 is used to play a guiding role when the side building beam 7 is installed. Since the side building beam 7 needs to be lifted by various devices during installation, when the length of the set insertion port 15 is short, there may be a certain gap between the installation of the side building beam 7 and the main building column 1 and the established angle. The provided installation frame 16 can make the side building beam 7 slide a certain distance in the installation frame 16 first when the side building beam 7 is installed. The sliding distance can correspond to the established installation angle. Through this section of the sliding distance, it is convenient to stabilize the angle when the side building beam 7 is installed.

[0036] On the opposite side walls of the installation frame 16, there are push blocks 25 connected by telescopic rods. The inclined surface of the push block 25 faces the moving direction of the side building beam 7. There is also a return spring between the push block 25 and the installation frame 16. The initial position of the push block 25 will block a small part of the installation frame 16. When the side building beam 7 is installed, the push block 25 will be pushed.

[0037] The installation frame 16 is slidably connected with a fastening plate 27. At one end of the fastening plate 27 located inside the installation frame 16, there is a triangular block 26 fixedly connected. The inclined surface of the triangular block 26 faces the right-angle side of the push block 25. The movement of the push block 25 can drive the triangular block 26 to move towards the main building column 1.

[0038] When the side building beam 7 moves into the installation frame 16, by contacting the inclined surface of the push block 25 through the side building beam 7 itself, the push block 25 is driven to move towards the side wall of the installation frame 16. When the push block 25 moves, under the action of the inclined surface of the triangular block 26, the fastening plate 27 is driven to move towards the main building column 1, and the connection between the fastening plate 27 and the main building column 1 will be closer. This can also play a role in stabilizing the connecting piece 3 to a certain extent.

[0039] In summary, this method can increase the stability between the connecting piece 3 and the main building column 1, thereby increasing the seismic resistance between the side building beam 7 and the main building column 1.
