Description

Technical Field

[0001] The present application relates to the technical field of earthquake resistance of assembled frame structures in civil engineering, and more specifically, to a composite energy-absorbing replaceable support device. Background Art

[0002] Prefabricated buildings are an inevitable way to achieve the industrialization of construction. As the country's requirements for the construction industry become higher and higher, prefabricated building technology has been widely used. However, the various performances of prefabricated buildings during the construction process, operation process and after the earthquake also show some problems with prefabricated buildings. For example, the energy consumption level is low, and the energy-consuming support structure is easily damaged and difficult to repair.

[0003] The energy dissipation support device is a device used for shock absorption of building structures. It absorbs external forces such as earthquakes through the plastic deformation of metal materials, reduces the vibration amplitude of the building structure, and achieves the shock absorption effect. Its main working principle is to utilize the plastic deformation characteristics of metal materials. When the building structure is affected by external forces such as earthquakes, the metal material inside the metal energy dissipation device will undergo plastic deformation, absorb part of the earthquake input energy and convert it into heat energy, thereby reducing the vibration amplitude of the structure. The performance of the metal energy dissipation device is stable and is not affected by factors such as temperature, humidity, and frequency. It has good durability and fatigue resistance. It can be applied to various types of buildings and earthquake intensity areas. It can be designed and manufactured according to different building structures and environmental conditions, and has strong adaptability.

[0004] At present, there are two main types of energy dissipation support devices in China: metal dampers and buckling restraint supports. Among them, metal dampers use the shear deformation or bending deformation of metal energy dissipation plates to dissipate seismic energy. They are generally installed through herringbone braces or concrete piers, which consumes a lot of additional steel and concrete. Buckling restraint supports use the tensile and compressive deformation of metal core plates to dissipate seismic energy. The purpose of setting the outer sleeve is to prevent the core plate from buckling. Under the same tensile and compressive deformation, the longer the support, the smaller the strain, and the smaller its energy dissipation density. The utility model invention adds constraint strips at the upper and lower cover plates, which can effectively limit the deformation of the structure, and sets bolt holes and oblong bolt holes on the upper and lower cover plates. The high-strength bolts are first stressed in the standard holes, which can make the structure plastically deformed when resisting deformation. After the bolt holes are damaged by force, the high-strength bolts at the oblong bolt holes are displaced to replace the damaged high-strength bolts and start working without reducing the bearing capacity of the device. The device is also provided with a replaceable metal belt. After the structure is damaged by force, the replaceable metal belt can be directly replaced, which can save steel and raw materials. Rubber is used as a filler between the replaceable metal belts, which can undergo plastic deformation when subjected to force and has a rebound force on the device, thereby increasing the stability of the device.

[0005] In order to solve the above problems, the present application provides a composite energy-consuming replaceable support device. Utility Model Content

[0008] Furthermore, the high-strength bolts located in the oblong bolt holes cooperate with the restraint strips to limit the core column.

[0009] Furthermore, the bolt holes on the inner side of the replaceable metal belt located in the core column are fixed by pins.

[0010] Furthermore, restraint strips are provided between the upper cover plate and the lower cover plate, and the restraint strips limit the core column.

[0011] Furthermore, the metal plates of the replaceable metal belt are filled with high-damping rubber blocks.

[0012] Furthermore, the upper cover plate and the lower cover plate are connected by high-strength bolts to connect the outer upper cover plate connecting bolt holes and the lower cover plate connecting threaded bolt holes.

[0013] Furthermore, the high-strength bolts connect the upper cover plate, the lower cover plate and the replaceable metal belt through the bolt holes and oblong bolt holes of the anchor steel pipe, the upper cover plate and the lower cover plate on the outside of the replaceable metal belt.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] The utility model increases the rigidity and strength of the steel plate, adds two ribs on the upper cover plate and the lower cover plate, adds an oblong hole on the upper cover plate, adds rubber between the replaceable support and the replaceable metal belt, and replaces the metal belt with a replaceable metal belt. Compared with traditional prefabricated nodes, the rigidity and strength of the steel plate are enhanced, and the device's ability to resist damage is increased. The ribs on the upper and lower cover plates effectively limit the deformation of the device and enhance the device's ability to resist earthquake deformation. The structure is simple, and no repair is required after the earthquake, or only some components need to be replaced to achieve post-earthquake repair of the structure. It is suitable for use in areas with frequent earthquakes. The added oblong holes cause the metal belt to undergo plastic deformation. After the standard holes are damaged by force, the oblong holes can continue to overcome the friction force, increasing the stability of the device without reducing the stability of the damper. Rubber is added between the metal belts to protect the metal belts from plastic deformation, and it also has partial resilience after the device is deformed, which has the function of protecting the device. According to the actual stress characteristics and energy consumption needs of the structure, by adjusting the performance of the bolts and metal plates, the preload of the high-strength bolts and other parameters, the seismic strength and energy consumption capacity of the support can be flexibly adjusted, and it can be more widely used in various types of buildings.

[0026] Example:

[0027] The present application embodiment discloses a composite energy-consuming replaceable support device, see Figure 1-Figure 5 , including a core column 2, an upper cover plate 1 and a lower cover plate 3, and a replaceable metal belt 12; the main body of the core column 2 is an I-beam structure with a bolt hole 6, the upper cover plate 1 includes a constraint strip 4, an oblong bolt hole 5, a bolt hole 6 and an upper cover plate connecting bolt hole 7, the lower cover plate 3 includes a constraint strip 4, an oblong bolt hole 5, a bolt hole 6 and a lower cover plate connecting wire bolt hole 8, the replaceable metal belt 12 includes a metal plate 13 and an anchoring steel pipe 14, the replaceable metal belt includes a metal plate 13 and an anchoring steel pipe 14, the middle of the replaceable metal belt 12 is filled with a high-damping rubber block 11, the core column 2 is placed in the constraint strip of the lower cover plate 3, the core column 2 and the replaceable metal belt 12 are fixed with a pin 9, the high-damping rubber block 11 is filled in the middle of the replaceable metal belt 12, and finally the upper cover plate 1, the lower cover plate 3 and the replaceable metal belt 12 are connected and fixed by high-strength bolts 10.

[0028] The upper cover plate 1 , the lower cover plate 3 and the core column 2 described above are integrally formed, and the replaceable metal belt 12 is formed by welding a metal plate 13 and an anchoring steel pipe 14 .

[0029] The upper cover plate 1 described above has no side walls, and the lower cover plate 3 has side walls. The upper cover plate 1 and the lower cover plate 3 are alternately provided with oblong bolt holes 5 and bolt holes 6, and the bolt holes between the upper and lower cover plates correspond to each other one by one, and the spacing between two adjacent bolt holes on the left and right is the same. The upper cover plate connection bolt holes 7 provided on the upper cover plate 1 correspond to the lower cover plate connection threaded bolt holes 8 provided on the lower cover plate 3, and the spacing between every two adjacent upper cover plate connection bolt holes 7 or lower cover plate connection threaded bolt holes 8 on the left and right is the same. The restraint strips 4 of the upper cover plate 1 and the lower cover plate 3 correspond to each other, and the net distance between the restraint strips 4 should be slightly larger than the width of the core column 2.

[0030] The core column 2 described above is similar to an I-shaped steel, with a hollow center. The bolt holes 6 opened on both sides correspond to the oblong bolt holes 5 or bolt holes 6 on the same side.

[0031] When the width or length of the high damping rubber block 11 is perpendicular to the replaceable metal belt 12 and the side wall of the lower cover plate 3, Figure 3 In the internal structure diagram, the clearance between two adjacent replaceable metal belts 12 is the same.

[0032] The high-strength bolts 10 mentioned above pass through the upper cover plate connection bolt holes 7 and are connected to the lower cover plate connection threaded bolt holes 8. The high-strength bolts 10 pass through the oblong bolt holes 5 or bolt holes 6 of the upper cover plate 1, the anchor steel pipe 14 and the oblong bolt holes 5 or bolt holes 6 of the lower cover plate 3 and are connected to the nuts. The pins 9 pass through the bolt holes 6, the anchor steel pipe 14 and the bolt holes 6 and are fixed.

[0033] The upper cover plate 1 and the lower cover plate 3 described above are connected by high-strength bolts 10. The replaceable metal belt 12 is connected to the upper cover plate 1 and the lower cover plate 3 by high-strength bolts 10, and is connected to the core column 2 by the pin 9. The high-damping rubber block 11 is filled into the gap between two adjacent replaceable metal belts 12, and is not connected to any components. For the convenience of construction, the core column 2 and the replaceable metal belt 12 can be temporarily connected to the lower cover plate 3 with industrial glue during installation, which facilitates the filling of the high-damping rubber block 11 and the insertion of the bolts after the upper cover plate 1 and the lower cover plate 3 are closed.

[0034] The bolt hole 6 described above does not allow the high-strength bolt 10 to move in translation, while the oblong bolt hole 5 allows the high-strength bolt 10 to move in translation. The high-strength bolt 10 passing through the oblong bolt hole 5 applies a pre-tightening force to provide a frictional resistance to the high-strength bolt 10 moving in translation in the oblong bolt hole 5. Appropriate pre-tightening force is applied so that the high-strength bolt 10 passing through the oblong bolt hole 5 does not move in translation when the metal plate 13 is in the elastic deformation stage, and the high-strength bolt 10 passing through the oblong bolt hole 5 moves in translation when the metal plate 13 in the replaceable metal belt 12 connected to the bolt hole 6 is in the plastic deformation stage. This ensures that when the replaceable metal belt 12 connected to the bolt hole 6 exits work due to excessive deformation of the metal plate 13, the replaceable metal belt 12 connected to the oblong bolt hole 5 can still work normally. This achieves the purpose of exiting work in stages, increasing the support strength reserve, increasing the allowable deformation of the support during normal operation, and meeting the principle of "no damage in small earthquakes, repairable in medium earthquakes, and no collapse in large earthquakes".

[0035] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
