Description

Technical Field

[0001] The invention relates to the technical field of shock absorption in construction engineering, and in particular to a buckling restrained brace with a temperature internal force release function. Background Art

[0002] Earthquake is a common natural disaster, which is characterized by strong suddenness and great destructive power. For a long time, in order to reduce the damage of earthquake disasters to houses and buildings, experts in the field of construction at home and abroad have explored and practiced various shock reduction methods. Practice has proved that energy dissipation and shock reduction technology is one of the effective means to reduce the seismic response of building structures. Its working principle is to attach shock-absorbing devices to the building structure. These shock-absorbing devices can absorb and dissipate the energy input into the building structure when an earthquake occurs, thereby reducing the seismic response of the building structure and achieving the purpose of protecting buildings and reducing disaster losses.

[0003] Buckling restrained brace (BRB) is an energy dissipation and shock absorption product proposed by Japanese scholars in the 1970s. It has the advantages of simple structure, low price and stable performance, and is widely used in earthquake-resistant design of houses. It exhibits good energy dissipation capacity when subjected to pressure and tension. This mechanical property enables it to provide the necessary stiffness and damping for the building structure, and reduce the seismic response of the structure when an earthquake occurs, thereby reducing the damage to the building structure caused by the earthquake.

[0004] The existing technology still has the following areas for improvement: the current buckling restrained supports can effectively improve the lateral stiffness when applied to large-span factories, but for extra-long buildings, the longer the length, the greater the structural internal forces and deformations caused by temperature effects. The induced temperature internal forces will cause long-term excessive stress in the main structure, affecting the life of the main structure. When setting up shock-absorbing devices, if buckling restrained supports are used alone, they can only resist earthquakes from the setting direction. If the force direction changes, the device's response ability is weak. Summary of the invention

[0005] In order to solve the above-mentioned problems existing in the prior art, the present invention provides a buckling restrained support with a temperature internal force release function, which can avoid long-term excessive stress of the main structure caused by temperature effects, ensure the service life of the main structure, and the device as a whole can cope with forces generated in multiple directions, thereby improving the overall seismic resistance of the device.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] A buckling restraint support with a temperature internal force release function, comprising a support assembly and a shock absorbing assembly, wherein the shock absorbing assembly is fixedly connected to the support assembly;

[0008] The support assembly includes a structural beam, a structural column, a node plate, an embedded part, a guide frame, a connecting block, a supporting column, a first mounting block and a second mounting block.

The second mounting blocks are provided in plurality, and the plurality of second mounting blocks are respectively fixedly connected to the vertices of both ends of another diagonal line of the mounting frame.

The buckling restraint support is fixedly connected to the adjacent node plate, the velocity locker is fixedly connected to the adjacent node plate, and the velocity locker is fixedly connected to the buckling restraint support through the connecting plate.

[0010] Preferably, the guide frame is provided in plurality, and the plurality of guide frames are respectively fixedly connected to both sides of the second mounting block, the guide frame is provided in a double V-shape, a plurality of through holes are provided on one V-shaped segment of the guide frame, the plurality of through holes on the guide frame are evenly distributed along the V-shaped segment of the guide frame, a fixing block is fixedly connected to the other V-shaped segment of the guide frame, and the support column is provided in plurality, and the plurality of support columns are respectively fixedly connected between the guide frame and the structural beam and between the guide frame and the structural column.

[0011] Preferably, a plurality of the first mounting blocks are provided, and the plurality of the first mounting blocks are fixedly connected between the guide frame and the node plate.

[0012] Preferably, the buckling restraining support comprises a core material and a restraining sleeve, the core material is located inside the restraining sleeve, and a non-adhesive material is used to fill the space between the core material and the restraining sleeve.

[0013] Preferably, the size of the connecting plate matches the size of the constraint sleeve hole, and a piston and a high-viscosity fluid are arranged inside the speed locker. The high-viscosity fluid is provided in multiple groups, and the multiple groups of high-viscosity fluid are respectively located on both sides of the piston.

[0014] Preferably, the friction damping assembly includes a first steel plate, a second steel plate, a third steel plate and a connecting piece, wherein two first steel plates are provided, and the two first steel plates are arranged horizontally, and a plurality of connecting pieces are provided, and the second steel plate and the third steel plate are respectively arranged on the upper and lower sides of the two first steel plates through a plurality of connecting pieces, and one first steel plate is rotatably connected to the second mounting block, and the other first steel plate is rotatably connected to the connecting block.

[0015] Preferably, the connecting member includes a bolt, a nut and a bearing.

[0016] Preferably, one end of the viscous damper is rotatably connected to the fixing block, and the other end of the viscous damper is rotatably connected to the connecting block.

[0017] Preferably, the connecting block is convexly arranged, and the connecting block is located at the intersection of the friction damping assembly and the adjacent sides of the viscous damper.

[0018] Preferably, the prestressed component is arranged parallel to the buckling restraint support, and the prestressed component includes a prestressed steel cable, an anchor plate and spiral reinforcement, the anchor plate is fixedly connected to the first mounting block, the spiral reinforcement is fixedly connected to the anchor plate, and the prestressed steel cable is fixedly connected to the anchor plate.

[0019] The beneficial effects of the present invention are:

[0020] (1) By setting the support assembly, the technical effect that can be achieved is that the through holes set on the guide frame can reduce the weight of the guide frame and reduce the production cost. The guide frame is located on both sides of the second mounting block, which is convenient for positioning and adjusting the installation direction of the friction damping assembly when the friction damping assembly is subsequently installed. The connecting block is located at the intersection of the adjacent sides of the friction damping assembly and the viscous damper, which is convenient for supporting the friction damping assembly and the viscous damper at the same time, so that the friction damping assembly and the viscous damper can cooperate with each other to cope with forces in multiple directions at the same time, and can provide more energy dissipation and damping effects.

[0021] (2) By setting up a shock-absorbing component, the technical effect that can be achieved is that the buckling restraint support and the velocity locker are connected in series. During the slow deformation of the components of the entire series system caused by changes in ambient temperature, the high-viscosity fluid on both sides of the piston inside the velocity locker can flow slowly without generating large internal forces, so as to adapt to the structural deformation caused by temperature changes, eliminate temperature internal forces, avoid long-term excessive stress of the main structure caused by temperature effects, and ensure the service life of the main structure. At the same time, under the action of wind loads, earthquake vibrations and other dynamic forces, the high-viscosity fluid on both sides of the piston inside the velocity locker cannot flow rapidly, showing high stiffness characteristics. The velocity locker is almost locked and motionless, forcing the core material inside the buckling restraint support to undergo plastic deformation, thereby retaining the stiffness properties of the buckling restraint support under dynamic action, allowing normal hysteresis energy dissipation or providing recovery stiffness for the structure.

[0022] (3) By setting up a shock-absorbing component, another technical effect that can be achieved is that the buckling restrained support dissipates seismic energy through internal elastic-plastic deformation during an earthquake. When the accumulated damage is large, it is inevitable to replace it. Since the velocity locker is connected in series, the entire series system has no residual internal force after the external load is removed, which facilitates the removal and replacement of the buckling restrained support.

[0023] (4) Through the coordination of the support assembly and the shock-absorbing assembly, the technical effect that can be achieved is that the prestressed steel cable applies prestress to the device, so that the structural beams and structural columns are subjected to pre-tension. The pre-tensioning force has a pre-compression effect on the buckling restrained support, so that the buckling restrained support can enter the working state under the action of a relatively small force, and can adapt to different earthquake magnitudes and dissipate earthquake energy. By simultaneously arranging the buckling restrained support, the friction damping assembly, the viscous damper, and the prestressed assembly, the various components can cooperate with each other to cope with the forces generated from all directions under the dynamic action of earthquake motion, and adapt to different earthquake magnitudes, so that the device as a whole can absorb and dissipate shock more effectively.

The node plates 6 are fixedly connected to the plurality of embedded parts 7. A plurality of second mounting blocks 15 are provided, and the plurality of second mounting blocks 15 are respectively fixedly connected to the vertices of both ends of another diagonal line of the mounting frame.

[0040] The shock absorbing assembly includes a buckling restraint support 1, a velocity locker 2, a connecting plate 3, a friction damping assembly 8, a viscous damper 9, a prestressed assembly 10 and a connecting block 12. The buckling restraint support 1 is fixedly connected to the adjacent node plate 6, the velocity locker 2 is fixedly connected to the adjacent node plate 6, and the velocity locker 2 is fixedly connected to the buckling restraint support 1 through the connecting plate 3.

[0041] Reference Figure 1 and Figure 2 , a plurality of guide frames 11 are provided, and the plurality of guide frames 11 are respectively fixedly connected to both sides of the second mounting block 15, and the guide frame 11 is arranged in a double V-shape, and a plurality of through holes are opened on a V-shaped section of the guide frame 11, and the plurality of through holes on the guide frame 11 are evenly distributed along the V-shaped section of the guide frame 11. The through holes provided on the guide frame 11 can reduce the weight of the guide frame 11 and reduce the production cost. A fixed block 901 is fixedly connected to the other V-shaped section of the guide frame 11, and a plurality of support columns 13 are provided, and the plurality of support columns 13 are respectively fixedly connected between the guide frame 11 and the structural beam 4 and between the guide frame 11 and the structural column 5; a plurality of first mounting blocks 14 are provided, and the plurality of first mounting blocks 14 are fixedly connected between the guide frame 11 and the node plate 6.

[0042] Reference Figures 7 to 9 The buckling restraint support 1 includes a core material 101 and a restraint sleeve 102, the core material 101 is located inside the restraint sleeve 102, and the core material 101 and the restraint sleeve 102 are filled with non-stick material; the size of the connecting plate 3 matches the size of the hole of the restraint sleeve 102, and a piston 103 and a high-viscosity fluid 104 are arranged inside the speed locker 2, and the high-viscosity fluid 104 is arranged in multiple groups, and the multiple groups of high-viscosity fluids 104 are located on both sides of the piston 103.

[0043] The buckling restraint support 1 is connected in series with the speed locker 2. During the slow deformation of the components of the entire series system caused by changes in ambient temperature, the high-viscosity fluid 104 on both sides of the piston 103 inside the speed locker 2 can flow slowly without generating large internal forces, so as to adapt to the structural deformation caused by temperature changes, eliminate temperature internal forces, avoid long-term excessive stress of the main structure caused by temperature effects, and ensure the service life of the main structure. At the same time, under the action of wind loads, earthquake vibrations and other dynamic forces, the high-viscosity fluid 104 on both sides of the piston 103 inside the speed locker 2 cannot flow rapidly, showing a high stiffness characteristic. The speed locker 2 is almost locked and motionless, forcing the core material 101 inside the buckling restraint support 1 to undergo plastic deformation, thereby retaining the stiffness properties of the buckling restraint support 1 under dynamic action, so as to achieve normal hysteresis energy dissipation or provide recovery stiffness for the structure.

[0044] The buckling restrained brace 1 dissipates seismic energy through internal elastic-plastic deformation during an earthquake, and inevitably needs to be replaced when the accumulated damage is large. Since the velocity locker 2 is connected in series, the entire series system has no residual internal force after the external load is removed, which facilitates the removal and replacement of the buckling restrained brace 1.

[0045] Reference Figures 1 to 4 The friction damping assembly 8 includes a first steel plate 801, a second steel plate 802, a third steel plate 803 and a connecting piece 804. Two first steel plates 801 are provided, and the two first steel plates 801 are arranged horizontally. There are multiple connecting pieces 804. The second steel plate 802 and the third steel plate 803 are respectively arranged on the upper and lower sides of the two first steel plates 801 through multiple connecting pieces 804. One first steel plate 801 is rotatably connected to the second mounting block 15, and the other first steel plate 801 is rotatably connected to the connecting block 12; the connecting piece 804 includes bolts, nuts and bearings.

[0046] The guide frames 11 are located on both sides of the second mounting block 15 , so as to facilitate the positioning and adjustment of the mounting direction of the friction damping assembly 8 when the friction damping assembly 8 is subsequently installed.

[0047] Reference Figures 1 to 4 One end of the viscous damper 9 is rotatably connected to the fixed block 901, and the other end of the viscous damper 9 is rotatably connected to the connecting block 12; the connecting block 12 is convexly arranged, and the connecting block 12 is located at the intersection of the adjacent sides of the friction damping component 8 and the viscous damper 9, so as to simultaneously support the friction damping component 8 and the viscous damper 9, so that the friction damping component 8 and the viscous damper 9 can cooperate with each other to cope with forces in multiple directions at the same time, and can provide more energy dissipation and damping effects.

[0048] Reference Figure 1 , Figure 2 and Figure 5 The prestressed component 10 is arranged parallel to the buckling restrained support 1. The prestressed component 10 includes a prestressed steel cable 1001, an anchor plate 1002 and a spiral rib 1003. The anchor plate 1002 is fixedly connected to the first mounting block 14, the spiral rib 1003 is fixedly connected to the anchor plate 1002, and the prestressed steel cable 1001 is fixedly connected to the anchor plate 1002. By setting the prestressed component 10, the prestressed steel cable 1001 applies prestress to the device, so that the structural beam 4 and the structural column 5 are subjected to pre-tensioning force, and the pre-tightening force pre-compresses the buckling restrained support 1, so that the buckling restrained support 1 can enter the working state under the action of a relatively small force, can adapt to different earthquake magnitudes, and dissipate earthquake energy.

[0049] The parameter setting process of buckling restraint support 1 and speed lock 2 is as follows:

[0050] The locking speed of the designed speed locker 2 is v 0, the design stroke iss 1, s 1 Adjust according to the temperature deformation amplitude of the structural components, s 1 should be greater than the maximum temperature deformation amplitude, and the design locking force is F 1. The locking displacement required to achieve the designed locking force is s 2. For the buckling restraint support 1 in series, it has an initial stiffness k 2 and ultimate load F 2.

[0051] In order to ensure that the speed lock 2 can be locked and force the buckling restraint support 1 to dissipate energy normally when locked under the action of power, the locking force is designed to be F 1 should be greater than the ultimate load of the buckling restrained support 1 F 2.

[0052] The overall initial stiffness is considered according to the stiffness of the series system, where the initial stiffness of the speed lock 2 is k 1 can be considered as: k 1= F 1 / S 2;

[0053] Then the initial stiffness of the overall series system is: k = k 1* k 2 / ( k 1+ k 2).

[0054] By simultaneously providing the buckling restraint support 1, the friction damping assembly 8, the viscous damper 9, and the prestressed assembly 10, the components can cooperate with each other to cope with the forces generated from all directions under the dynamic action of earthquake motion and other dynamic forces, and adapt to different earthquake magnitudes, so that the device as a whole can absorb and dissipate shock more effectively.

[0055] The working principle and use process of the present invention are as follows: when the device is in a stable state, the prestressed steel cable 1001 applies prestress to the device, so that the structural beam 4 and the structural column 5 are subjected to pre-tensioning force, and the pre-tensioning force has a pre-extrusion effect on the buckling restraint support 1, so that the buckling restraint support 1 can enter the working state under the action of a relatively small force, can adapt to different earthquake magnitudes, and dissipate earthquake energy.

[0056] When slow deformation occurs under the action of ambient temperature changes, the high-viscosity fluid 104 on both sides of the piston 103 inside the speed lock 2 can flow slowly without generating large internal forces, so as to adapt to the structural deformation caused by temperature changes and eliminate temperature internal forces.

[0057] Under the action of dynamic forces such as earthquakes, the high-viscosity fluid 104 on both sides of the piston 103 inside the speed locker 2 cannot flow quickly and smoothly, showing a high stiffness characteristic. The speed locker 2 is almost locked and motionless, which can force the core material 101 inside the buckling restraint support 1 to undergo plastic deformation to dissipate seismic energy. When dynamic forces such as earthquakes are generated from multiple directions, the friction damping component 8, the viscous damper 9 and the buckling restraint support 1 can cooperate with each other to provide more energy dissipation and damping effects.

[0058] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
