Description

Technical Field

[0001] The present invention relates to the field of building steel structures, and specifically relates to a seismic reinforcement connection system and connection method for building structures. Background Art

[0002] A steel structure is a structure composed of steel materials and is one of the main types of building structures. The structure is mainly composed of components such as steel beams, steel columns, and steel trusses made of section steel and steel plates. When connecting steel structures, welding is usually used for fixation. Therefore, once the building shakes due to strong vibrations, the steel will bend or even break, causing serious damage to the building.

[0003] For this reason, Chinese Patent Application CN114482275A discloses a building seismic building steel structure and its connection method. After installing the vertical plate on the support column through fixing bolts, the I-beam is placed on the cross plate, and the movable plate descends under the pressure of the I-beam to bear the load. Subsequently, the automatic fixing mechanism is rotated through the screw rod to make it close to the cross plate and clamp the I-beam at the same time, so that the I-beam is fixed on the support column. On the one hand, the cross plate and the automatic fixing mechanism form a clamping force to clamp and fix the I-beam, making the connection method of the I-beam and the support column different from the welding connection method, and relatively more convenient and efficient than the welding method, and more labor-saving. On the other hand, the components on the cross plate are used to relieve the I-beam to the greatest extent when it is shaken, and enhance the seismic effect of the I-beam, making the I-beam more stable after connection. And after the I-beam is placed on the movable plate, the seismic pad will be in direct contact with the I-beam. When the seismic pad contacts the I-beam, the shock-absorbing balls and balloons in the fixing sleeve will enhance the friction between the I-beam and the cross plate fixation, and at the same time, it can be relieved to a certain extent through the shock-absorbing balls and balloons when vibrations occur. The aerated concrete block improves the load-bearing effect of the cross plate on the I-beam through the characteristics of its own materials, and at the same time can effectively enhance the seismic resistance of the I-beam.

[0004] However, the building steel structures disclosed in the prior art use air pressure to form a buffer structure and cooperate with shock-absorbing balls and balloons for support and shock absorption, which has certain requirements for the airtightness of the structure, resulting in a significant increase in its cost, and can only buffer and shock absorb within a certain range. Once the building shakes due to strong vibrations, its airtightness will be affected, losing most of its buffer and shock absorption capabilities, and once it exceeds its buffer range, the steel will still bend and break.

[0047] To further understand the features, technical means, specific purposes, and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0048] Refer to Figures 1 - 3 : An anti-seismic reinforcement connection system for a building structure, comprising a cross beam 1, a vertical support structure 2, a hinge structure 3, and a locking structure 4; the vertical support structure 2 includes a vertical rod 21 and a telescopic rod 22, the vertical rod 21 is slidably engaged with the telescopic rod 22, and the vertical rod 21 and the telescopic rod 22 are connected by the locking structure 4; the hinge structure 3 includes a hinge shaft 31 and a hinge portion, the hinge shaft 31 is installed on the cross beam 1, the hinge portion is installed at the top end of the vertical rod 21, and the hinge portion is rotatably connected to the hinge shaft 31.

[0049] The present invention realizes the function of greatly improving the toughness of the building structure through the cross beam 1, the vertical support structure 2, and the hinge structure 3, achieving the effect of automatic expansion and contraction and sliding when shaken by a strong earthquake, greatly avoiding the bending and fracture of the steel structure, and solving the problem of structural damage of traditional building structures when shaken by a strong earthquake. In order to ensure its stability, traditional building structures usually adopt a rigid connection method, but this method is extremely prone to bending and cracking of steel when encountering a strong earthquake. Once the steel structure is damaged, it will cause irreversible damage to the building; therefore, the vertical support structure 2 and the hinge structure 3 are designed. When the building structure is shaken by a strong earthquake, the cross beam 1, the vertical rod 21, and the telescopic rod 22 used for support will be shaken under the influence of the earthquake. At this time, the vertical support structure 2 will produce relative sliding under the action of tension and be connected and fixed by the locking structure 4 to maintain the support capacity of the vertical support structure 2. At the same time, due to the shaking of the cross beam 1 at the top, the vertical rod 21 and the cross beam 1 rotate reciprocally along the hinge shaft 31, avoiding the twisting and cracking of the connection point between the vertical rod 21 and the cross beam 1. Through the telescopic ability of the vertical support structure 2 and the rotation ability of the hinge structure 3, the toughness of the building structure connection system is greatly improved, avoiding irreversible damage to the steel, enabling it to still have support capacity after shaking, preventing the building structure from being severely damaged, and greatly improving the safety performance of the building structure.

[0050] Refer to Figure 1 、 Figure 4 、 Figure 5 and Figure 6: The locking structure 4 includes a one-way locking block 41 and a first elastic member 42; the one-way locking block 41 is slidably mounted on the telescopic rod 22, and the two ends of the first elastic member 42 are respectively connected to the one-way locking block 41 and the telescopic rod 22. Locking grooves 211 that cooperate with the locking block are provided on the vertical rod 21, and at least two locking grooves 211 are provided.

[0051] The one-way locking block 41 has an inclined surface, and the inclined surface of the one-way locking block 41 faces downward.

[0052] The present invention realizes the function of connecting the vertical rod 21 and the telescopic rod 22 through the one-way locking block 41, the locking groove 211 and the first elastic member 42, and achieves the effect of one-way locking the vertical rod 21 and preventing the vertical rod 21 from sliding down after extending. When the building structure is strongly shaken, the cross beam 1, the vertical rod 21 and the telescopic rod 22 for support will be shaken and sway. At this time, the vertical support structure 2 will relatively slide and elongate under the action of tension. The vertical rod 21 presses the inclined surface of the one-way locking block 41, thereby overcoming the elastic force of the first elastic member 42 and making it slide towards the telescopic rod 22. The vertical rod 21 elongates. As the vertical rod 21 slides, when the one-way locking block 41 slides to the next locking groove 211, it slides into the locking groove 211 under the elastic force of the first elastic member 42, thereby maintaining the support capacity of the vertical support structure 2. At the same time, due to the sway of the cross beam 1 at the top, the vertical rod 21 and the cross beam 1 rotate reciprocally along the hinge axis 31, avoiding distortion and cracking at the connection point between the vertical rod 21 and the cross beam 1.

[0053] Refer to Figure 1 、 Figure 4 and Figure 5 : The locking structure 4 further includes a longitudinal buffer assembly 43. The longitudinal buffer assembly 43 includes a buffer seat 431, a top plate 432 and a second elastic member 432; the buffer seat 431 is slidably mounted on the telescopic rod 22, the one-way locking block 41 is slidably mounted on the buffer seat 431, and the two ends of the first elastic member 42 are respectively connected to the buffer seat 431 and the one-way locking block 41. The top plate 432 is mounted on the telescopic rod 22 and is located at the top end of the telescopic rod 22, and the two ends of the second elastic member 432 are respectively connected to the buffer seat 431 and the top plate 432.

[0054] A first damping rod 4321 is further provided between the top plate 432 and the buffer seat 431, and the two ends of the first damping rod 4321 are respectively connected to the top plate 432 and the buffer seat 431.

[0055] The present invention realizes the function that the vertical rod 21 can still perform relative sliding within a certain range relative to the telescopic rod 22 after being locked by the one-way locking block 41 through the buffer seat 431, the top plate 432 and the first elastic member 42, and cooperates with the first damping rod 4321 to achieve a damping effect. The first damping rod 4321 is preferably a hydraulic damping rod; when the building structure is subjected to strong vibrations, the vertical support structure 2 shakes. As the amplitude of the shaking changes, the vertical rod 21 slides along the telescopic rod 22 and elongates, and the hinge structure 3 rotates. As the shaking continues, the vertical rod 21 slides reciprocally along the telescopic rod 22 under the action of the tensile force, and the one-way locking block 41 cooperates with the locking groove 211 on the vertical rod 21. Therefore, the buffer seat 431 slides relative to the telescopic rod 22, thereby pulling the second elastic member 432 and the first damping rod 4321. The second elastic member 432 expands and contracts repeatedly, and the first damping rod 4321 releases the mechanical energy as heat during the expansion and contraction process, thereby absorbing the energy of the vibration and achieving an obvious damping effect.

[0056] Refer to Figure 1 , Figure 4 , Figure 5 and Figure 6 : The locking structure 4 further includes a control component 44, and the control component 44 includes a control piece 441 and an inclined wedge block 442; the control piece 441 is slidably mounted on the buffer seat 431, the control piece 441 is connected to the one-way locking block 41, and both ends of the first elastic member 42 are respectively connected to the control piece 441 and the buffer seat 431. The inclined wedge block 442 is in abutting fit with the control piece 441 and is connected to the top plate 432.

[0057] The inclined wedge block 442 has two inclined surfaces, and the control piece 441 has two inclined surfaces that cooperate with the inclined wedge block 442. When the inclined wedge block 442 slides along the telescopic rod 22, it will squeeze the inclined surface of the control piece 441, thereby driving the control piece 441 to slide along the buffer seat 431.

[0058] The present invention realizes the function of controlling the sliding of the one-way locking block 41 through the control piece 441 and the inclined wedge block 442, achieving the effect that when the second elastic member 432 expands and contracts to a certain value, the locking of the one-way locking block 41 is automatically released. When the building structure is subjected to strong vibrations, the vertical support structure 2 shakes. As the amplitude of the shaking changes, the vertical rod 21 slides along the telescopic rod 22 and elongates, and the hinge structure 3 rotates. As the shaking continues, the vertical rod 21 slides reciprocally along the telescopic rod 22 under the action of the pulling force, thereby causing the second elastic member 432 and the first damping rod 4321 to expand and contract. When the amplitude of the shaking increases, the expansion and contraction amplitudes of the second elastic member 432 and the first damping rod 4321 increase accordingly. The buffer seat 431 drives the inclined wedge block 442 to slide, and the inclined wedge block 442 presses the control piece 441, thereby pushing the control piece 441 to slide, overcoming the elastic force of the first elastic member 42 and driving the one-way locking block 41 to slide towards the telescopic rod 22, releasing the locking of the vertical rod 21, enabling it to freely expand and contract under the action of the pulling force. The buffer seat 431 loses the restriction of the one-way locking block 41 and slides under the elastic force of the second elastic member 432, releasing the elastic force of the second elastic member 432, reducing its elastic force, thereby causing the inclined wedge block 442 to reset, and the control piece 441 to reset under the elastic force of the first elastic member 42, and again having the one-way locking ability until the amplitude of the shaking increases again.

[0059] Refer to Figure 1 , Figure 2 , Figure 7 , Figure 8 and Figure 9 : The hinge structure 3 further includes a lateral buffer assembly 33. The lateral buffer assembly 33 includes a guide rail 331 and a support wheel 332; the guide rail 331 is installed on the cross beam 1, and the support wheel 332 is rotatably installed in the guide rail 331, and the hinge shaft 31 is inserted on the support wheel 332.

[0060] The present invention realizes the function of lateral buffering of the hinge structure 3 along the cross beam 1 through the guide rail 331, the support wheel 332, the abutting block 341 and the guide rod 343, achieving the effect of further improving the structural stability of the connection system. When the building structure is subjected to strong vibrations, especially in multi-story buildings, the lower cross beam 1 will have a relative displacement with the upper cross beam 1. Although the vertical support structure 2 can expand and contract to adapt to the shaking, when the offset of the cross beam 1 is relatively large, the inclination of the vertical support structure 2 will be relatively serious, thereby causing its supporting ability to decline and the steel to be easily bent; for this reason, a lateral buffer assembly 33 is provided. When the offset of the cross beam 1 is relatively large, the vertical rod 21 will pull the hinge end 32, and the hinge end 32 drives the hinge shaft 31 and the support wheel 332, thereby causing the support wheel 332 to roll along the guide rail 331, thereby reducing the inclination of the vertical support structure 2, maintaining the supporting ability of the vertical support structure 2, and greatly improving the seismic resistance of the building structure.

[0061] Refer toFigure 1 , Figure 2 , Figure 7 and Figure 8 : The hinge structure 3 also includes an abutment block 341, a third elastic member 342 and a guide rod 343. The abutment block 341 is slidably installed in the guide rail 331 and is rotatably connected to the hinge shaft 31. The two ends of the third elastic member 342 are respectively connected to the abutment block 341 and the guide rail 331. The guide rod 343 is connected to the abutment block 341 and is slidably matched with the guide rail 331.

[0062] End covers 344 are installed at both ends of the guide rail 331 . The end covers 344 are connected to the guide rail 331 through bolts 345 . The guide rod 343 and the end covers 344 are slidably matched.

[0063] The present invention realizes the function of automatic reset of the hinge shaft 31 through the abutment block 341, the third elastic member 342 and the guide rod 343, so as to achieve the effect of automatic reset of the hinge shaft 31 when the shaking of the building structure is reduced, so that the building structure can automatically recover when the vibration is reduced. When the vibration is large, the offset of the beam 1 will also increase accordingly. At this time, the hinge shaft 31 will drive the support wheel 332 to move along the guide rail 331, thereby avoiding the vertical support structure 2 from tilting too much, and retaining the supporting capacity of the vertical support structure 2 as much as possible. When the vibration is reduced or stopped, the offset of the beam 1 gradually decreases, and the abutment block 341 moves under the elastic force of the third elastic member 342. At the same time, the abutment block 341 drives the hinge shaft 31, so that the hinge shaft 31 returns to the middle position of the guide rail 331, and the building structure is reset as a whole.

[0064] Reference Figure 1 , Figure 2 , Figures 7 - 10 : The vertical support structure 2 also includes a second reset assembly 23, which includes a sliding seat 231, a mounting seat 232, an articulated seat 233 and a fourth elastic member 234; the sliding seat 231 is connected to one end of the guide rod 343 away from the abutment block 341, and a first fixed shaft 2311 is installed on the sliding seat 231; the mounting seat 232 is installed on the telescopic rod 22, and a second fixed shaft 2221 is installed on the mounting seat; two articulated seats 233 are provided, and the two first articulated seats 233 are respectively rotatably installed on the first fixed shaft 2311 and the second fixed shaft 2221; the two ends of the fourth elastic member 234 are respectively connected to the two articulated seats 233.

[0065] The present invention realizes the function of automatic reset of the vertical support structure 2 through the sliding seat 231, the mounting seat 232, the hinge seat 233 and the fourth elastic member 234, achieving the effect that the vertical support structure 2 automatically returns to the vertical state when the external force is removed. A second damping rod 2341 is further arranged between the two hinge seats 233, and both ends of the second damping rod 2341 are respectively connected to the two hinge seats 233. The second damping rod 2341 is preferably a hydraulic damping rod; when the vibration decreases or stops, the hinge structure 3 is reset under the action of the first reset assembly 34, while the vertical support structure 2 has not yet returned to the vertical state. As the offset of the cross beam 1 gradually decreases, under the action of the third elastic member 342 and the fourth elastic member 234, the vertical rod 21 is subjected to a downward pressure, the buffer seat 431 pulls the second elastic member 432, and then drives the inclined wedge block 442 to slide. The inclined wedge block 442 pushes the control piece 441, and further releases the restriction of the one-way locking block 41 on the vertical rod 21, so that the vertical rod 21 contracts to complete the reset; and during the shaking of the building structure, the cross beam 1 may shake left and right. At this time, the fourth elastic member 234 continuously undergoes contraction deformation, driving the second damping rod 2341 to contract accordingly, and further continuously absorbing vibrations and reducing the shaking amplitude of the building structure, further improving the seismic resistance of the building structure.

[0066] Refer to Figure 1 and Figure 2 : There are two cross beams 1 and two hinge structures 3. The two cross beams 1 are respectively connected to the vertical rod 21 and the telescopic rod 22 through the two hinge structures 3, and the two cross beams 1 are distributed vertically up and down.

[0067] The present invention realizes the improvement of the overall seismic resistance of the building structure through the two cross beams 1 and the two hinge structures 3, achieving the effect of improving the overall toughness. The hinge structure 3 completely replaces the traditional rigid connection, and through the locking structure 4, the vertical support structure 2 can flexibly switch between the two states of free expansion and contraction and rigid connection. Therefore, when a strong earthquake occurs, it can not only adapt to the vibration but also retain the support ability, so that the building structure will not be damaged destructively during the vibration process, and continuously absorb vibrations under the action of the first reset assembly 34 and the second reset assembly 23, reduce the shaking amplitude of the building structure, and return to the initial state after the vibration decreases or stops, retaining the original performance of the building structure.

[0068] Refer to Figure 7 and Figure 8 : Reinforcing ribs 2312 are arranged on the sliding seat 231, and the sliding seat 231 is in sliding fit with the guide rail 331.

[0069] The present invention realizes the function of strengthening the structural strength of the strengthening crossbeam 1 through the sliding seat 231, the reinforcing rib 2312, the guide rod 343, the abutting block 341 and the guide rail 331. When the crossbeam 1 deflects, the supporting wheel 332 rolls along the guide rail 331, thereby causing the guide rod 343 and the sliding seat 231 to slide. The guide rail 331 is fixedly installed on the crossbeam 1, and the strength of the crossbeam 1 is improved under the supporting action of the sliding seat 231 and the guide rail 331, and it can further prevent it from bending under the action of vibration, thereby improving its overall structural strength.
