Description

Technical Field

[0001] The present application relates to the field of earthquake-resistant building structures, and in particular to an earthquake-resistant building structure system and a column and support beam connection structure thereof. Background Art

[0002] Prefabricated buildings are a type of building that transports various building components to the construction site and then assembles the various building components into the main building body. It has the advantage of fast construction speed.

[0003] In the existing related technologies, the column and supporting beam connection structure of the prefabricated building structure, that is, the beam-column connection node, is generally rigidly connected by bolts to ensure the connection strength of the beam-column connection node of the prefabricated building, thereby ensuring the structural safety of the prefabricated building.

[0004] With regard to the above-mentioned related technologies, the beam-column joints rigidly connected by bolts are difficult to absorb the impact force generated by earthquakes, resulting in poor stability of the beam-column joints during earthquakes, which is not conducive to ensuring the structural safety of prefabricated buildings. Summary of the invention

[0005] In order to ensure the stability of the beam-column joints during an earthquake, thereby ensuring the structural safety of prefabricated buildings, the present application provides a column and support beam connection structure.

[0006] The present application provides a column and support beam connection structure adopting the following technical solution: A column and supporting beam connection structure, comprising a column, a crossbeam and a shock absorbing assembly, wherein the column is fixedly installed on the ground, and the crossbeam is located on the top of the column; The shock absorbing assembly comprises a housing, an energy storage flywheel, a transmission wheel, a transmission outer gear ring and a transmission rack, wherein the energy storage flywheel is rotationally matched with the housing, the transmission wheel is coaxially mounted on the energy storage flywheel, and the transmission wheel is mounted on the transmission outer gear ring through an elastic energy storage member, and the transmission rack is slidingly matched with the housing and meshed with the transmission outer gear ring; The crossbeam is slidably matched with the housing, and the crossbeam is connected to the transmission rack.

[0007] By adopting the above technical solution, when the crossbeam shakes or deforms under the action of an earthquake, it drives the transmission rack to slide, and then drives the transmission outer ring gear to rotate. The transmission outer ring gear drives the transmission wheel to rotate through the elastic energy storage component, and then drives the energy storage flywheel to rotate. When the transmission outer ring gear drives the transmission wheel to rotate through the elastic energy storage component, the energy of the crossbeam shaking or deformation is stored in the elastic energy storage component. When the elastic energy storage component restores its own deformation during an earthquake, the energy storage flywheel accelerates the rotation, and the elastic potential energy stored in itself is transferred to the kinetic energy of the energy storage flywheel, and then the energy generated by the shaking or deformation of the crossbeam is transferred to the energy storage flywheel, thereby ensuring the stability of the beam-column node during an earthquake and ensuring the structural safety of the prefabricated building.

[0008] Optionally, the transmission wheels are provided in plurality, and the plurality of transmission wheels are divided into two groups, and the two groups of energy storage flywheels are respectively located on both sides of the transmission outer gear ring; There are a plurality of energy storage flywheels, and the plurality of energy storage flywheels are respectively arranged in one-to-one correspondence with each transmission wheel; The two groups of transmission wheels are connected to the energy storage flywheel through a one-way transmission member; The one-way transmission member comprises an inner ratchet, a driving rotating wheel and an inner pawl, wherein the inner ratchet is coaxially fixedly mounted on the energy storage flywheel, the driving rotating wheel is coaxially fixedly mounted on the transmission rotating wheel, and the inner pawl is rotatably matched with the driving rotating wheel through a pawl elastic member and meshes with the ratchet teeth of the inner ratchet; The ratchet teeth of the inner ratchet wheels corresponding to the two groups of transmission wheels face in opposite directions.

[0009] By adopting the above technical solution, when the crossbeam drives the transmission rack to slide in one direction under the action of an earthquake, the transmission wheel drives the active wheel to rotate, so that the inner pawl is tightly fitted with the ratchet teeth on the inner side of the inner ratchet wheel, thereby driving one group of energy storage flywheels to rotate through the inner ratchet wheel.

[0010] When the beam drives the transmission rack to slide in another opposite direction under the action of an earthquake, the transmission rotating wheel rotates in the opposite direction, driving the previous active rotating wheel to rotate in the opposite direction, and the inner pawl does not mesh with the ratchet teeth of the inner ratchet wheel, so that the previous energy storage flywheel continues to rotate in the previous direction; At the same time, the transmission rack drives another set of energy storage flywheels to rotate in the opposite direction through another set of transmission wheels, so that the energy of the reciprocating swing of the beam under the action of the earthquake is absorbed by the two sets of energy storage flywheels rotating in opposite directions, thereby ensuring the stability of the beam-column node during an earthquake and ensuring the structural safety of the prefabricated building.

[0011] Optionally, the elastic energy storage component is a spring, one end of the elastic energy storage component is mounted on the transmission wheel, and the other end of the elastic energy storage component is mounted on the transmission outer gear ring.

[0012] By adopting the above technical solution, when the transmission outer gear ring drives the transmission wheel to rotate through the elastic energy storage component, the two ends of the elastic energy storage component rotate while the elastic energy storage component itself stretches or compresses, thereby storing the energy of the shaking or deformation of the beam in the elastic energy storage component, so that at the early stage of an earthquake, the elastic energy storage component can be used to drive the energy storage flywheel with a larger mass to overcome its own inertia to start rotating, thereby reducing the situation where the transmission rack directly hits the transmission outer gear ring to consume the energy of the shaking or deformation of the beam due to the energy storage flywheel not rotating in time, thereby reducing the occurrence of damage to the transmission outer gear ring or the transmission rack.

[0013] Optionally, the shell is provided with a shell chamber and a shell slide groove, the shell chamber is provided inside the shell, and the energy storage flywheel, the transmission wheel and the transmission outer gear ring; The housing slide groove is communicated with the housing chamber, and the housing slide groove extends along the length direction of the crossbeam. The crossbeam is installed on the transmission rack through a rubber block, and the rubber block is slidably matched with the housing slide groove.

[0014] By adopting the above technical solution, when the crossbeam shakes or deforms under the action of an earthquake, the transmission rack is driven to slide through the rubber block, so that at the beginning of the earthquake, the large-mass energy storage flywheel that overcomes its own inertia is driven to start rotating through the transmission outer gear ring, thereby reducing the occurrence of fractures caused by the connection between the crossbeam and the transmission rack being subjected to large stress due to the energy storage flywheel not rotating in time.

[0015] Optionally, the housing is fixedly mounted with a slide rail, the slide rail extends along the length direction of the crossbeam, the slide rail is slidably matched with a slider, and the crossbeam is fixedly mounted on the slider.

[0016] By adopting the above technical solution, the outer shell is slidably matched with the outer shell through sliders and slide rails. On the premise of ensuring stability under normal circumstances, it is ensured that the connection structure between the column and the supporting beam has sufficient freedom to absorb or transfer the energy of the earthquake when an earthquake occurs, thereby ensuring the stability of the beam-column node when an earthquake occurs and ensuring the structural safety of the prefabricated building.

[0017] Optionally, an auxiliary damper is provided between the shell and the cross beam, one end of the auxiliary damper is rotationally engaged with the shell, and the other end of the auxiliary damper is rotationally engaged with the cross beam.

[0018] By adopting the above technical solution, on the one hand, the auxiliary damper ensures the stability under normal circumstances, and on the other hand, provides damping when the beam shakes or deforms under the action of an earthquake, so as to reduce the impact of the earthquake on the connection structure between the column and the supporting beam.

[0019] Optionally, the outer shell is provided with a rack groove, the cross-section of the rack groove is "T"-shaped, the rack groove extends along the length direction of the crossbeam, the transmission rack is integrally connected with a rack protrusion, the rack protrusion slides and fits in the rack groove, and the rack protrusion is close to the inner wall of the rack groove.

[0020] By adopting the above technical solution, the rack protrusion slides and cooperates with the rack groove, which is beneficial to ensure the sliding stability of the transmission rack.

[0021] Optionally, the type of the column is a steel column, and the type of the beam is a steel beam.

[0022] By adopting the above technical solution, the unit weight of the columns and beams is small, which reduces the inertial effect of the columns and beams under earthquake action, helps to ensure the stability of the column and supporting beam connection structure during an earthquake, and ensures the structural safety of the prefabricated building.

[0023] The present application also provides an earthquake-resistant building structure system, which adopts the following technical solution: An earthquake-resistant building structure system comprises the above-mentioned column and supporting beam connection structure.

[0024] Optionally, it also includes a steel frame and a connecting damper, one end of the connecting damper is rotationally matched with the steel frame, and the other end of the connecting damper is rotationally matched with the crossbeam.

[0025] By adopting the above technical solution, the steel frame supports the building load under normal circumstances, thereby ensuring the structural stability of the prefabricated building; when an earthquake occurs, the deformation and displacement of the steel frame act on the beam through the connecting damper, and then shock absorption is achieved through the shock-absorbing assembly.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. When the crossbeam shakes or deforms under the action of an earthquake, it drives the transmission rack to slide, and then drives the transmission outer ring gear to rotate. The transmission outer ring gear drives the transmission wheel to rotate through the elastic energy storage component, and then drives the energy storage flywheel to rotate. When the transmission outer ring gear drives the transmission wheel to rotate through the elastic energy storage component, the energy from the shaking or deformation of the crossbeam is stored in the elastic energy storage component. When the elastic energy storage component restores its own deformation during an earthquake, the energy storage flywheel accelerates its rotation, and transfers its own stored elastic potential energy into the kinetic energy of the energy storage flywheel, and then transfers the energy generated by the shaking or deformation of the crossbeam to the energy storage flywheel, thereby ensuring the stability of the beam-column node during an earthquake and ensuring the structural safety of the prefabricated building.

[0027] 2. When the crossbeam drives the transmission rack to slide in one direction under the action of an earthquake, the transmission wheel drives the active wheel to rotate, so that the inner pawl fits tightly against the ratchet teeth on the inner side of the inner ratchet wheel, thereby driving one set of energy storage flywheels to rotate through the inner ratchet wheel.

[0028] When the beam drives the transmission rack to slide in another opposite direction under the action of an earthquake, the transmission rotating wheel rotates in the opposite direction, driving the previous active rotating wheel to rotate in the opposite direction, and the inner pawl does not mesh with the ratchet teeth of the inner ratchet wheel, so that the previous energy storage flywheel continues to rotate in the previous direction; At the same time, the transmission rack drives another set of energy storage flywheels to rotate in the opposite direction through another set of transmission wheels, so that the energy of the reciprocating swing of the beam under the action of the earthquake is absorbed by the two sets of energy storage flywheels rotating in opposite directions, thereby ensuring the stability of the beam-column node during an earthquake and ensuring the structural safety of the prefabricated building.

[0029] 3. When the transmission outer gear ring drives the transmission wheel to rotate through the elastic energy storage component, the two ends of the elastic energy storage component rotate while the elastic energy storage component itself stretches or compresses, thereby storing the energy of the beam shaking or deformation in the elastic energy storage component, so that in the early stage of an earthquake, the elastic energy storage component can be used to drive the larger mass energy storage flywheel that overcomes its own inertia to start rotating, thereby reducing the situation where the energy storage flywheel fails to rotate in time, causing the transmission rack to directly hit the transmission outer gear ring to consume the energy of the beam shaking or deformation, thereby causing the transmission outer gear ring or transmission rack to be damaged.

[0052] The implementation principle of the column and support beam connection structure of the embodiment of the present application is as follows: when the cross beam 2 slides toward one end of the slide rail 311 under the action of an earthquake, the piston rods of the two auxiliary dampers 4 extend or shorten, producing a damping effect on the cross beam 2.

One end of the connecting damper 7, that is, the piston rod, is hinged to the column 1 of the steel frame 6, and the other end of the connecting damper 7, that is, the cylinder block, is hinged to the top of the cross beam 2, so that when the steel frame 6 shakes or deforms under the action of an earthquake, the energy of the shaking or deformation is transferred to the cross beam 2 through the connecting damper 7, and further transferred to the two energy storage flywheels 32 by the cross beam 2.
