Description

Technical Field

[0001] The present invention relates to the technical field of structural engineering, and in particular to an assembled beam-column node connection device. Background Art

[0002] Traditional construction methods usually involve pouring concrete and tying steel bars on site, which is not only time-consuming and labor-intensive, but also has a significant impact on the environment. In contrast, prefabricated buildings can effectively improve construction efficiency, reduce wet work on site, and reduce environmental pollution by prefabricating components in factories and assembling them quickly on site. However, the development of prefabricated buildings also faces some challenges, one of which is how to ensure the effective connection of beam-column nodes to meet structural safety and performance requirements.

[0003] According to the patent with authorization announcement number CN112095790B, an assembled steel structure beam-column node connection device is disclosed, including an upper round steel tube column, a lower round steel tube column and a crossbeam, the upper round steel tube column is fixedly connected to a first columnar sleeve, the first columnar sleeve is fixedly connected to a first connecting plate, the first connecting plate is fixedly connected to a first fixed plate, the lower round steel tube column is fixedly connected to a second columnar sleeve, and the second columnar sleeve is fixedly connected to four second connecting plates; the above-mentioned connection device realizes rapid connection of the beam-column node through bolts, but there are still some shortcomings in practical applications. Specifically, since the connection stress between the crossbeam and the beam-column node mainly depends on the fixed bolts for bearing, and the thread bearing capacity of the bolts is limited, when the crossbeam is subjected to lateral force or eccentric load, the connection node may produce large torsional or bending deformation, further aggravating the force load of the bolts, easily causing the bolts to slip or break, and increasing the risk of structural failure. Summary of the invention

[0004] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides a prefabricated beam-column node connection device to improve the seismic resistance of the prefabricated beam-column connection node.

[0013] The beneficial effects of the present invention are: 1.

[0028] Embodiment 1: A prefabricated beam-column node connection device, such as Figure 1-Figure 5As shown, it includes an installation frame 3 and a docking frame 4. The installation frame 3 is fixedly installed on the top of the beam column 1. The installation frame 3 serves as the assembly body of the present connection device. The installation frame 3 is a cross frame. The four sides of the installation frame 3 are all set as "I"-shaped frames. The four sides of the installation frame 3 are respectively slidably docked with the docking frames 4. The frame ends of the docking frame 4 are used to fix the cross beam 2. The cross beam 2 is connected to the four corners of the installation frame 3 on the top of the beam column 1 through the docking frame 4; it also includes a buffer ring 32, a buffer pad 33, a card block 5 and a reinforcement component 6. Locking grooves 31 are opened in the four frames of the installation frame 3, and the inner sides of the locking grooves 31 of the installation frame 3 are provided with buffers. A punch ring 32, a buffer pad 33 is provided between the four frame bodies of the installation frame 3 and the docking gap of the docking frame 4, a card slot adapted to the locking slot 31 is opened at the docking frame 4 of the installation frame 3, a card block 5 is clamped between the installation frame 3 and the docking frame 4, and the card block 5 is used to firmly connect the docking frame 4 to the "I"-shaped frame on the four sides of the installation frame 3, and a reinforcement component 6 is provided between the docking frame 4 and the side wall of the beam column 1; the reinforcement component 6 includes a mounting plate 61, a fixing plate 62, a sliding plate 63, a connecting plate 64 and a fastening bolt 65, the mounting plate 61 is fixedly installed on the top of the beam column 1, and the mounting plate 61 is distributed at the bottom of the four corners of the mounting frame 3, and fixed The plate 62 is fixedly connected to the side wall at the top of the beam column 1, and the fixed plate 62 is slidably connected with a sliding plate 63. The sliding plate 63 and the mounting plate 61 are connected by a connecting plate 64. A plurality of bolt holes 41 are provided at the joint of the sliding plate 63 and the frame body of the docking frame 4. The fastening bolts 65 pass through the bolt holes 41 on the sliding plate 63 and the docking frame 4 on the same side in sequence and are fixed by nuts. When the crossbeam 2 is docked and installed on the beam column 1, the docking frame 4 fixedly connected on the crossbeam 2 is slidably docked to the "I"-shaped frame on the four sides of the mounting frame 3 in sequence, and the card slot on the docking frame 4 is aligned with the locking slot 31 on the mounting frame 3, and the card block 5 is inserted and inserted. , so that the docking frame 4 on the four-way crossbeam 2 is spliced ​​and installed on the installation frame 3 of the beam column 1, and at the same time, the sliding plate 63 and the docking frame 4 are bolted together by the fastening bolts 65, and then the connecting plate 64 on the sliding plate 63 is connected to the installation plate 61, so that the installation frame 3 and the docking frame 4 are non-rigidly connected. Under the action of the buffer ring 32 and the buffer pad 33, the sliding plate 63 that can slide on the fixed plate 62 is cooperated to provide a certain activity and buffer distance when vibration occurs, reduce the impact of direct impact force on the node, avoid excessive stress causing the fastening bolts 65 to be easily deformed and broken, and enhance the seismic resistance of the connection on the beam column 1.

[0029] like Figure 3 and Figure 4 As shown, the buffer ring 32 and the buffer pad 33 are specifically rubber blocks, and the buffer ring 32 and the buffer pad 33 are used to absorb vibrations between the beam column 1 and the cross beam 2, protect key connection parts such as the fastening bolts 65 from direct impact of dynamic loads, and reduce the risk of fatigue damage caused by repeated vibrations.

[0030] like Figure 4 and Figure 5 As shown, there is a certain distance between the joint of the mounting frame 3 and the docking frame 4, and the distance is used to provide necessary expansion and contraction room. A screw groove for connecting the mounting plate 61 and the sliding plate 63 is opened on the connecting plate 64, and the connecting plate 64 is provided with a movable distance on the sliding plate 63. When vibrating, the sliding plate 63 will vibrate in the mounting frame 3 following the docking frame 4 connected by the bolts, and cooperate with the buffer ring 32 and the buffer pad 33 to consume the vibration energy, thereby ensuring the safety of the connection of the fastening bolt 65.

[0031] like Figure 3 and Figure 4 As shown, the card block 5 is specifically a "Z"-shaped block, and the locking groove 31 of the installation frame 3 and the card groove of the docking frame 4 are both "Z"-shaped grooves adapted to the card block 5. The "Z"-shaped card block 5 can provide a limiting effect in multiple directions between the installation frame 3 and the docking frame 4, effectively dispersing stress and reducing local stress concentration, thereby improving the connection stiffness of the entire node.

[0032] When the present connection device is used on the beam column, the cross-shaped mounting frame 3 is fixed to the top of the beam column 1 by welding or bolts. The four sides of the mounting frame 3 adopt an "I"-shaped cross-section design, and a longitudinally extending locking groove 31 is provided inside the mounting frame 3. The buffer ring 32 and the buffer pad 33 on the mounting frame 3 are used to absorb vibration energy. When the docking frame 4 at the end of the crossbeam 2 is slid and inserted along the "I"-shaped track of the mounting frame 3, the gap between the two is filled with the elastic buffer pad 33 to form the first shock-absorbing barrier. After the slots on the side walls of the docking frame 4 are aligned with the locking slots 31 of the mounting frame 3, the "Z"-shaped clamping block 5 is inserted. The folded line structure of the clamping block 5 simultaneously limits the horizontal and vertical displacements, and converts the rigid connection between the docking frame 4 and the mounting frame 3 into a multi-directional limit to avoid stress concentration. After the clamping block 5 is fixed, the reinforcement component 6 is intervened to enhance the stability of the node. The mounting plates 61 located at the four corners of the top of the beam column 1 and The fixed plate 62 of the side wall constitutes a basic support frame, and the sliding plate 63 that can slide laterally is flexibly connected to the mounting plate 61 through screws between the connecting plate 64. The operator sequentially passes the fastening bolts 65 through the sliding plate 63 and the bolt holes 41 of the docking frame 4 and locks them, so that the beam 2 and the beam column 1 form a non-rigid connection. When the building vibrates due to an earthquake or wind load, the vibration energy of the beam 2 is transmitted to the mounting frame 3 through the docking frame 4. At this time, the buffer ring 32 compresses and deforms to absorb high-frequency impacts, and the buffer pad 33 dissipates low-frequency vibrations through shear deformation. At the same time, the sliding plate 63 moves slightly laterally along the fixed plate 62, and the connecting plate 64 expands and contracts with the sliding plate 63, forcing the vibration energy to be released through the flexible hinge point, greatly reducing the shear force borne by the fastening bolts 65. Therefore, the balance between node strength and seismic performance is achieved through the three-level coordinated mechanism of the block 5 limiting, buffering energy absorption and flexible energy consumption.

[0033] like Figure 1 , Figure 6 and Figure 7As shown, the side walls of the docking frame 4 are fixedly provided with slide rails 71, and the docking frame 4 is slidably installed with a protective frame 7 through the slide rails 71. The protective frame 7 is an aerial frame with an opening on one side. The protective frame 7 is used to limit and protect the card block 5. The protective frame 7 can completely cover the periphery of the card block 5 to prevent the card block 5 stuck between the installation frame 3 and the docking frame 4 from loosening, thereby extending the service life of the card block 5.

[0034] like Figure 6 and Figure 7 As shown, a first magnet 8 is fixedly installed on the side of a protective frame 7 on one side that is perpendicular to each other at the four top corners of the installation frame 3, and a second magnet 81 is embedded and fixed on the end face of the protective frame 7 on the other side that is perpendicular to each other. The first magnet 8 and the second magnet 81 have different magnetic poles and are adapted to each other. When the protective frame 7 blocks and limits the corresponding block 5 on the same side, the first magnet 8 and the second magnet 81 are attracted to each other, so that the two protective frames 7 at the top corners of the installation frame 3 can be attracted together, and the block 5 can be limited and protected, so that the maintenance personnel can open the protective frame 7 to perform maintenance operations on the block 5.

[0035] After completing the node connection between the installation frame 3 and the docking frame 4, in order to protect the key card block 5 and enhance the durability of the node, the slide rail 71 on the side wall of the docking frame 4 is first used as a guide base, and the operator pushes the protective frame 7 horizontally along the slide rail 71 to make the protective frame 7 completely cover the card block 5 and the joint area between the installation frame 3 and the docking frame 4. At this time, the card block 5 will be blocked and limited by the protective frames 7 on both sides. When the protective frame 7 slides to the limited protection position, the first magnet 8 and the second magnet 81 are attracted to each other by opposite poles, so that the two adjacent protective frames 7 are tightly fitted to form a stable protective layer, and at the same time, the axial displacement of the card block 5 is constrained. In daily use, the magnetic attraction ensures that the protective frame 7 is firmly covered to avoid vibration that causes the card block 5 to loosen; when maintenance is required, the maintenance personnel only need to gently push the protective frame 7 in the opposite direction along the slide rail 71. After the magnetic attraction is overcome, it can be separated, and the card block 5 is directly exposed for replacement or reinforcement.

[0036] Embodiment 2: Based on embodiment 1, Figure 8 and Fig. 9 As shown, a buffer member 9 is provided between the mounting plate 61 and the corresponding sliding plate 63 on the same side, and the buffer member 9 includes a mounting block 91, a damper 92 and a fixed block 93. A mounting block 91 is fixedly installed on each mounting plate 61, and a fixed block 93 is fixedly connected to the top surface of the sliding plate 63. A damper 92 is connected between the fixed block 93 and the adjacent mounting block 91, and one end of the damper 92 is hinged to the fixed block 93, and the other end of the damper 92 is hinged to the mounting block 91. The damper 92 is used to absorb and dissipate vibration energy between the mounting plate 61 and the sliding plate 63 to reduce the wear caused by vibration on the connection between the mounting frame 3 and the docking frame 4.

[0037] like Figure 8 and Fig. 9As shown, a trigger member 10 for triggering an external alarm is provided on the mounting plate 61, and the trigger member 10 includes a mounting sleeve 101, a contact sensor 102 and a striker rod 103. The mounting sleeve 101 is fixedly installed on the top surface of the mounting plate 61, and a slide groove is provided on the sleeve of the mounting sleeve 101. Contact sensors 102 are symmetrically mounted on both ends of the sleeve of the mounting sleeve 101. The contact sensor 102 has a built-in controller for controlling an external alarm. A striker rod 103 is fixedly connected to the outer shell of the damper 92, and the rod end of the striker rod 103 is located in the sleeve slide groove of the mounting sleeve 101. The striker rod 103 is used to trigger the contact sensor 102. When the connecting structure of the beam column 1 and the cross beam 2 vibrates and pulls the damper 92, the damper 92 drives the striker rod 103 to hit any contact sensor 102, and the contact sensor 102 controls the external alarm through the controller to alarm, thereby warning personnel that the building is vibrating and they need to evacuate as soon as possible.

[0038] In terms of vibration control and safety warning, when the vibration of the beam 2 is transmitted to the sliding plate 63, the lateral displacement of the sliding plate 63 drives the piston rod of the damper 92 to expand and contract, and the kinetic energy is converted into heat energy through the internal friction of the hydraulic oil, which significantly attenuates the vibration amplitude and reduces the structural wear between the docking frame 4 and the mounting frame 3. When the vibration intensity of the damper 92 exceeds the limit, the violent expansion and contraction of the damper 92 pushes the impact rod 103 to move at high speed in the slide groove. If the impact rod 103 hits any sensor, the sensor immediately activates the external sound and light alarm through the built-in circuit, and sends a warning signal to the building management system, thereby buying critical time for personnel evacuation and emergency intervention, thereby improving the safety level of the building node.

[0039] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
