Description

Technical Field

[0001] This invention relates to the field of bridge structure technology, and more specifically, to a steel bridge pier and its manufacturing method. Background Technology

[0002] Reinforced concrete structures are widely used in bridge engineering, especially reinforced concrete piers, due to their high compressive strength and good plasticity. However, investigations have revealed significant drawbacks of reinforced concrete piers, such as their heavy weight, poor ductility, and susceptibility to damage in the plastic hinge region during earthquakes, leading to significant challenges in subsequent repairs. Currently, a new type of box-shaped steel pier is also being developed. For example, application number 201510357180.3 describes a novel steel pier that is increasingly being used due to its lightweight, ease of processing, high strength, and good ductility. However, box-shaped steel piers are prone to local buckling and ultra-low cycle fatigue failure during earthquakes, leading to pier failure, and repairs are cumbersome, requiring the replacement of the entire pier. Furthermore, the environments faced by bridge engineering today are more complex, necessitating the development of a new pier structure to effectively address the problems of local buckling and ultra-low cycle fatigue failure in box-shaped piers, thereby extending the service life of steel piers. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a steel bridge pier to solve the above problems.

[0004] The present invention adopts the following solution:

[0005] This application provides a steel bridge pier, comprising a pier cap, an energy dissipation section, and at least one standard section that are assembled and connected from bottom to top;

[0006] The energy-consuming section includes a first box-shaped steel pier body and a first steel pier inner body that conforms to the shape of the first box-shaped steel pier body; the standard section includes a second box-shaped steel pier body and a second steel pier inner body that conforms to the shape of the second box-shaped steel pier body; each steel pier inner body includes multiple steel pipe columns, multiple transverse diaphragms, and multiple partitions; each transverse diaphragm is connected between the multiple steel pipe columns to form a hollow structure; each partition is connected between the box-shaped steel pier body and the steel pier inner body; rubber concrete is poured between the box-shaped steel pier body and the steel pier inner body, and inside the steel pipe columns;

[0007] The energy-consuming section further includes an energy-consuming plate, which is connected to the transverse diaphragm of the energy-consuming section by a first bolt and to the first box-shaped steel pier body by a second bolt.

[0008] Furthermore, steel pipe shear keys are provided on the top of the pier cap and the top of the steel pipe columns of the energy dissipation section and the standard section; connection holes for connecting the steel pipe shear keys are reserved at the bottom of the steel pipe columns of the energy dissipation section and the standard section.

[0009] Furthermore, the energy-dissipating section also includes multiple energy-dissipating rods, one end of which is connected to the outer perimeter of the first box-shaped steel pier body, and the other end of which is connected to the pier cap.

[0010] Furthermore, the energy dissipation rod includes a first energy dissipation rod connected to the outer perimeter of the first box-shaped steel pier body, a second energy dissipation rod connected to the pier platform corresponding to the first energy dissipation rod, and a steel sleeve for connecting the first energy dissipation rod and the second energy dissipation rod.

[0011] Furthermore, the upper and lower ends of the box-type steel pier body have outwardly extending fixing plates; the fixing plates are provided with multiple bolt holes; the pier cap is provided with connecting holes; the bolt holes facilitate the connection between two box-type steel pier bodies; the connecting holes and the bolt holes facilitate the connection between the box-type steel pier body and the pier cap by bolts.

[0012] Furthermore, stiffening ribs that connect to the fixing plate are also provided on the bottom and top sides of the box-shaped steel pier body.

[0013] Furthermore, it also includes a cap beam, the bottom of which is provided with a connection hole for connecting the steel pipe shear key.

[0014] Furthermore, the partition plate is provided with multiple connecting holes.

[0015] Furthermore, the shear key of the steel pipe is filled with rubber concrete.

[0016] This invention provides a steel bridge pier, comprising a pier cap, an energy-dissipating section, and at least one standard section connected sequentially from bottom to top. The energy-dissipating section and the standard section include an outer box-shaped steel pier body and an inner steel pier body connected to the inner side of the box-shaped steel pier body. By pouring rubber concrete between the box-shaped steel pier body and the inner steel pier body, as well as inside the steel pipe column, problems such as durability, local buckling, and ultra-low cycle fatigue failure of the steel bridge pier are effectively solved. Simultaneously, an energy-dissipating plate is also installed within the energy-dissipating section, which can improve the overall energy dissipation capacity of the pier, extend its service life, and facilitate rapid replacement of the pier in the event of earthquake damage through segmental assembly.

[0017] The present invention also provides a method for manufacturing steel bridge piers, comprising the following steps:

[0018] S1: Construct a foundation at a designated location on the construction site, pour rubber concrete into the foundation, weld steel pipe shear keys onto the foundation, and reserve bolt holes on the foundation.

[0019] The energy-consuming section is processed by sequentially welding multiple steel pipe columns and multiple transverse diaphragms to form the inner body of the first steel pier; fixing the energy-consuming plate to both sides of the transverse diaphragm with studs; welding multiple diaphragms between the first box-shaped steel pier body and the inner body of the first steel pier; connecting the energy-consuming plate to the first box-shaped steel pier body with bolts; welding the energy-consuming rod to the outer side of the first box-shaped steel pier body; pouring rubber concrete between the first box-shaped steel pier body and the inner body of the first steel pier and inside the steel pipe columns, and connecting steel pipe shear keys to the upper end of the steel pipe columns, and reserving connection holes at the lower end of the steel pipe columns for connecting steel pipe shear keys;

[0020] The standard section is fabricated by sequentially welding multiple steel pipe columns and multiple transverse diaphragms to form the inner body of the second steel pier; welding multiple diaphragms between the second box-shaped steel pier body and the inner body of the second steel pier; pouring rubber concrete between the second box-shaped steel pier body and the inner body of the second steel pier and inside the steel pipe columns, and connecting steel pipe shear keys at the upper end of the steel pipe columns, and reserving connection holes at the lower end of the steel pipe columns for connecting the steel pipe shear keys; fabricating the cap beam at the prefabrication plant, and reserving bolt holes and connection holes for connecting steel pipe shear keys at the bottom of the cap beam;

[0021] S2: Connect the energy-dissipating section to the steel pipe shear key on the bearing platform through the connection hole of the steel pipe shear key and fix it with bolts. At the same time, connect and fix the energy-dissipating rod to the bearing platform. Then connect the standard section to the steel pipe shear key of the energy-dissipating section through the connection hole of the steel pipe shear key and fix it with bolts.

[0022] S3: If there is only one standard section, the pier assembly is complete; if there are multiple standard sections, based on S2, the next standard section is connected to the steel pipe shear key of the previous standard section through the connection hole of the steel pipe shear key and fixed with bolts.

[0023] S4: Repeat steps S2 or S3 to assemble the two piers, place the cap beam on the two piers, connect the cap beam to the steel pipe shear key on the standard section through the connection hole of the steel pipe shear key at the bottom of the cap beam, and fix it with bolts.

[0024] This invention provides a method for manufacturing steel bridge piers. Compared with traditional reinforced concrete bridge piers, the method combines steel bridge piers with rubber concrete, which greatly reduces the self-weight of the bridge pier, improves its ductility, and significantly enhances the energy dissipation capacity of the bridge pier by setting energy-dissipating plates and energy-dissipating rods, thereby increasing the service life of the bridge pier. At the same time, the abutment, energy-dissipating section, standard section and cap beam can all be prefabricated independently and then assembled and fixed by steel pipe shear keys and bolts, which greatly shortens the construction period of the entire bridge pier. In the event of damage or failure of the bridge pier due to an earthquake, the bridge pier can be quickly repaired or replaced. Attached Figure Description

[0037] Example

[0038] Combination Figures 1 to 9 As shown, this embodiment provides a steel bridge pier, including a pier cap 13, an energy-dissipating section, and at least one standard section that are assembled and connected sequentially from bottom to top;

[0039] The energy-consuming section includes a first box-shaped steel pier body 4, and a first steel pier inner body that is placed inside the first box-shaped steel pier body 4 and conforms to the shape of the first box-shaped steel pier body 4; the standard section includes a second box-shaped steel pier body 5, and a second steel pier inner body that is placed inside the second box-shaped steel pier body 5 and conforms to the shape of the second box-shaped steel pier body 5; each steel pier inner body includes multiple steel pipe columns 16, multiple transverse diaphragms 157, and multiple partitions 15; each transverse diaphragm 157 is connected between multiple steel pipe columns 16 to form a hollow structure; each partition 15 is connected between the box-shaped steel pier body and the steel pier inner body; rubber concrete 2 is poured between the box-shaped steel pier body and the steel pier inner body, and inside the steel pipe columns 16.

[0040] The energy-consuming section further includes an energy-consuming plate 9, which is connected to the transverse diaphragm 157 of the energy-consuming section by a first bolt 17 and to the first box-type steel pier body 4 by a second bolt 18.

[0041] In this embodiment, the pier cap 13 serves as the foundation of the entire pier and needs to be poured at a designated location on the construction site. Bolt holes and steel pipe shear keys 3 for connection are pre-reserved on the pier cap 13, and rubber concrete 2 is poured inside the steel pipe shear keys 3. Both the energy-dissipating section and the standard section can be prefabricated in a prefabrication plant and then transported to the construction site for assembly and connection with the pier cap 13. The first box-shaped steel pier body 4 of the energy-dissipating section and the second box-shaped steel pier body 5 of the standard section have the same structure, both being square steel piers. The inner body structure of the first steel pier and the inner body structure of the second steel pier are also the same, both including four evenly distributed circular steel pipe columns 16. Four transverse diaphragms 157 are welded between the four steel pipe columns 16, forming a shape similar to the box-shaped steel pier body, and are welded inside the box-shaped steel pier body through the diaphragms 15.

[0042] like Figure 4 and Figure 5 As shown, the energy-consuming section includes four partitions 15, which are respectively connected by welding between the steel pipe column 16 and the corner of the first box-shaped steel pier body 4; Figure 2 and Figure 3 As shown, the standard section includes eight partitions 15, four of which are connected between the steel pipe column 16 and the corner of the second box-shaped steel pier body 5, and the other four are connected between the transverse partition 157 and the second box-shaped steel pier body 5. The energy-dissipating section is also equipped with four energy-dissipating plates 9, which are energy-dissipating steel plates. They are connected to the transverse partition 157 of the energy-dissipating section by first bolts 17 and to the first box-shaped steel pier body 4 by second bolts 18. The energy-dissipating plates 9 can improve the energy dissipation capacity of the pier.

[0043] Rubber concrete 2 is poured between the box-type steel pier body and the inner body of the steel pier, and inside the steel pipe column 16. This effectively solves problems such as the durability, local buckling, and ultra-low cycle fatigue failure of the steel pier, improves the deformation capacity of the steel pier, and utilizes waste rubber, which is in line with the national concept of sustainable development. Steel pipe shear keys 3 are welded to the top of the steel pipe columns 16 in the energy-dissipating section and the standard section. When pouring rubber concrete 2 in the energy-dissipating section and the standard section, connection holes 19 are pre-drilled at the bottom of the steel pipe columns 16 to connect the steel pipe shear keys 3. The connection holes 19 at the bottom of the energy-dissipating section are used to connect the steel pipe shear keys 3 on the pier cap 13, and the connection holes 19 at the bottom of the standard section are used to connect the steel pipe shear keys 3 on the energy-dissipating section. The steel pipe shear key 3 is filled with rubber concrete 2 inside. The use of steel pipe shear key 3 for connection can effectively improve the strength and shear capacity of the joint, ensuring that the structure meets the seismic requirements of "strong node and weak member". On the other hand, it can avoid the problem of the upper structure collapsing when the upper and lower segments are spliced.

[0044] In this embodiment, as Figure 1 As shown, the upper and lower ends of the box-type steel pier body extend outwards with fixing plates 8. The fixing plates 8 have multiple bolt holes, and the upper and lower segments are connected by steel pipe shear keys 3 and fixed with bolts through the bolt holes on the fixing plates 8. The pier cap 13 has connecting holes 19. The energy-dissipating section of the box-type steel pier body is bolted to the connecting holes 19 on the pier cap 13 through the bolt holes on the fixing plates 8. The bottom and top sides of the box-type steel pier body are also provided with stiffening ribs 6 connected to the fixing plates 8. These stiffening ribs 6 strengthen the connection between the box-type steel pier body and the fixing plates 8, better ensuring the connection stability between the upper and lower segments. In this embodiment, the steel pipe shear key 3 is cylindrical, with a diameter not greater than the inner diameter of the steel pipe column 16, and can be fitted inside the steel pipe column 16.

[0045] In this embodiment, as Figure 7 As shown, the energy-dissipating section also includes multiple energy-dissipating rods connected between the outer side of the first box-shaped steel pier body 4 and the abutment 13. Each energy-dissipating rod includes a first energy-dissipating rod 10, a second energy-dissipating rod 11, and a steel sleeve 12. The first energy-dissipating rod 10 is L-shaped, with one end welded to the outer perimeter of the first box-shaped steel pier body 4 and the other end facing the abutment 13. One end of the second energy-dissipating rod 11 is connected to the abutment 13 via a nut, and the other end is connected to the other end of the first energy-dissipating rod 10 via the steel sleeve 12. This divides the energy-dissipating rod into two parts and connects them using the steel sleeve 12, facilitating the connection between the energy-dissipating section and the abutment 13. Of course, the number of energy-dissipating rods can be adjusted according to the size of the pier and the surrounding environment.

[0046] Furthermore, such as Figure 1 and Figure 9 As shown, it also includes a cap beam 1, which can also be prefabricated in a prefabrication plant. It only needs to have a connection hole 19 for connecting the steel pipe shear key 3 and a bolt hole pre-drilled at its bottom to facilitate installation and connection with the standard section.

[0047] Furthermore, the partition 15 is provided with multiple connecting holes, which facilitate the flow of rubber concrete 2 and enable faster filling of the multiple pouring spaces separated by the partition 15 in the energy-consuming section and the standard section. At the same time, the multiple separated spaces are connected by the connecting holes to realize the transmission of vibration and quickly achieve the effect of vibration reduction.

[0048] This invention provides a steel bridge pier, comprising a pier cap 13, an energy-dissipating section, and at least one standard section connected sequentially from bottom to top. The energy-dissipating section and the standard section include an outer box-shaped steel pier body and an inner steel pier body connected to the inner side of the box-shaped steel pier body. By pouring rubber concrete 2 between the box-shaped steel pier body and the inner steel pier body, and inside the steel pipe column 16, the problems of durability, local buckling, and ultra-low cycle fatigue failure of the steel bridge pier are effectively solved. At the same time, an energy-dissipating plate 9 is also provided in the energy-dissipating section, which can improve the overall energy dissipation capacity of the bridge pier, extend the service life of the bridge pier, and facilitate rapid replacement of the bridge pier in the event of earthquake damage by adopting segmental assembly connection.

[0049] The present invention also provides a method for manufacturing steel bridge piers, comprising the following steps:

[0050] S1: Cast the foundation 13 at the designated location on the construction site, pour rubber concrete 2 into the foundation 13, weld steel pipe shear keys 3 onto the foundation 13, and reserve bolt holes on the foundation 13.

[0051] The energy-consuming section is processed by sequentially welding multiple steel pipe columns 16 and multiple transverse diaphragms 157 to form the inner body of the first steel pier; fixing the energy-consuming plate 9 to both sides of the transverse diaphragm 157 with studs; welding multiple diaphragms 15 between the first box-shaped steel pier body 4 and the inner body of the first steel pier; connecting the energy-consuming plate 9 to the first box-shaped steel pier body 4 with bolts; welding the energy-consuming rod to the outer side of the first box-shaped steel pier body 4; pouring rubber concrete 2 between the first box-shaped steel pier body 4 and the inner body of the first steel pier and inside the steel pipe columns 16, and connecting steel pipe shear keys 3 to the upper end of the steel pipe columns 16, and reserving connection holes 19 at the lower end of the steel pipe columns 16 for connecting the steel pipe shear keys 3.

[0052] The standard section is processed by sequentially welding multiple steel pipe columns 16 and multiple transverse diaphragms 157 to form the inner body of the second steel pier; welding multiple diaphragms 15 between the second box-shaped steel pier body 5 and the inner body of the second steel pier; pouring rubber concrete 2 between the second box-shaped steel pier body 5 and the inner body of the second steel pier and inside the steel pipe columns 16, and connecting steel pipe shear keys 3 at the upper end of the steel pipe columns 16, and reserving connecting holes 19 at the lower end of the steel pipe columns 16 for connecting steel pipe shear keys 3.

[0053] The cap beam 1 is fabricated in the prefabrication plant, and bolt holes and connection holes 19 for connecting steel pipe shear keys 3 are reserved at the bottom of the cap beam 1.

[0054] S2: Connect the energy-consuming section to the steel pipe shear key 3 on the bearing platform 13 through the connecting hole 19 of the steel pipe shear key 3 and fix it with bolts. At the same time, connect and fix the energy-consuming rod to the bearing platform 13. Then connect the standard section to the steel pipe shear key 3 of the energy-consuming section through the connecting hole 19 of the steel pipe shear key 3 and fix it with bolts.

[0055] S3: If there is only one standard section, the assembly of a single pier is completed; if there are multiple standard sections, based on S2, the next standard section is connected to the steel pipe shear key 3 of the previous standard section through the connecting hole 19 of the steel pipe shear key 3 and fixed with bolts.

[0056] S4: Repeat steps S2 or S3 to assemble the two piers, and place the cap beam 1 on the two piers. Connect the cap beam 1 to the steel pipe shear key 3 on the standard section through the connection hole 19 of the steel pipe shear key 3 at the bottom of the cap beam 1, and fix it with bolts.

[0057] This invention provides a method for manufacturing steel bridge piers. Compared with traditional reinforced concrete bridge piers, the method combines steel bridge piers with rubber concrete 2, which greatly reduces the self-weight of the bridge pier and improves its ductility. Furthermore, the energy dissipation capacity of the bridge pier is greatly improved by setting up energy dissipation plates 9 and energy dissipation rods, thus extending the service life of the bridge pier. At the same time, the pier cap 13, energy dissipation section, standard section and cap beam 1 can all be independently prefabricated and then assembled and fixed by steel pipe shear keys 3 and bolts, which greatly shortens the construction period of the entire bridge pier. In the event of damage or failure of the bridge pier due to an earthquake, the bridge pier can be quickly repaired or replaced.
