Description

Technical Field

[0001] This invention relates to the field of bridge seismic protection technology, specifically to a steel cable-connected bridge seismic protection structure and its construction method. Background Technology

[0002] Currently, it is relatively rare for bridge superstructures to be destroyed directly due to seismic dynamics, but beam collapse caused by the failure of support connectors is more common. Generally, solutions include installing suitable seismic blocks on the cap beams, or installing tie rods or other connecting devices between main beams or between main beams and piers (abutments) to prevent beam collapse and limit excessive displacement of the main beams under strong earthquakes.

[0003] However, all of the above-mentioned seismic isolation structures are rigid structures. The impact force between the main beam and the seismic isolation structure will directly act on the pier structure, which may cause shear failure of the pier and reduce the safety of the bridge. Summary of the Invention

[0004] This application provides a bridge seismic-resistant structure with steel cable connection and its construction method, which can reduce shear damage to bridge piers and improve bridge safety.

[0005] On one hand, this application provides a steel cable-connected bridge seismic isolation structure, which includes a corbel cast at the bottom of a diaphragm; two cables, one end of each cable embedded in a cap beam, and the other ends of the two cables connected to a connecting cable to prevent detachment. The connecting cable passes through the corbel, and an energy-dissipating component is provided at the connection between the cables and the connecting cable. In the initial stage of main beam movement, both the cables and the connecting cable can move relative to the energy-dissipating component, and the energy-dissipating component dissipates energy from the movement of the cables and the connecting cable. When the movement of the main beam causes the energy-dissipating component to fail, the cables tighten the connecting cable.

[0006] In one embodiment, the energy-consuming component includes: a housing with an open end, two friction elements disposed within the housing, the ends of the cable and the connecting cable passing through the side wall of the housing and located between the two friction elements; and a pressing element connected to the open end of the housing for pressing the two friction elements, thereby causing the two friction elements to generate resistance to the movement of the cable and the connecting cable relative to the housing.

[0007] In one embodiment, two resistance parts are disposed opposite to each other at the open end of the housing, the extruder is connected to the two resistance parts, one of which is used to prevent the cable from detaching from the housing, and the other resistance part is used to prevent the connecting cable from detaching from the housing.

[0008] In one embodiment, the cable is folded in half, with the two ends of the folded cable embedded in the cap beam, and one of the resistance parts is fitted onto the folded portion; the connecting cable is arranged in a loop, with its end connected to the end of the cable in a chain-like manner, and another resistance part is fitted onto it.

[0009] In one embodiment, the open end of the housing is fitted with a collar that prevents the resistance part from opening outward from the housing.

[0010] In one embodiment, a through-tube is embedded in the cow leg, and the connecting cable passes through the through-tube through the cow leg.

[0011] In one embodiment, a partition is fixed inside the tube, and the partition is located within the annular space of the connecting cable.

[0012] In one embodiment, the corbel includes a concrete block and reinforcing bars. The concrete block and the diaphragm are cast integrally. The two ends of the reinforcing bars are embedded in the diaphragm and connected to the reinforcing bars in the diaphragm. The middle part of the reinforcing bars is bent and embedded in the concrete block. The connecting cable passes through the space of the middle bend of the reinforcing bars.

[0013] On the other hand, this application also provides a construction method for an earthquake-resistant structure, which includes the following steps: positioning two cables, extending one end of the cables into the cap beam formwork, and casting the cap beam concrete in place; setting the formwork for the corbel and diaphragm, and removing the formwork for the corbel and diaphragm after the diaphragm and corbel are cast; connecting the connecting cable and the two cables to prevent detachment, so that the connecting cable passes through the corbel and ensures that the connecting cable and the cables have a certain relative displacement; and installing energy dissipation components at the connection point of the connecting cable and the cables.

[0014] In one embodiment, before positioning the two cables, the method further includes: folding each cable in half, with the two ends of the folded cable placed inside the cap beam and the bent portion extending out of the cap beam; and connecting the connecting cable and the cable to prevent detachment, with the connecting cable passing through the corbel. The specific steps are as follows: one end of a steel cable is first passed through the bent portion of the steel cable of the corbel and one side of the cap beam, then it is passed through the steel cable of the corbel and the other side of the cap beam, and the two ends of the steel cable are fixed to form a connecting cable.

[0015] The beneficial effects of the technical solutions provided in this application include at least the following:

[0016] During an earthquake, in the initial stage of main girder movement, both the cables and connecting cables move relative to the energy-dissipating components, which absorb energy from this movement. When the main girder displacement becomes larger, the cables and connecting cables are connected to prevent detachment; the cables tighten the connecting cables, which in turn tighten the main girder via corbels, effectively limiting the main girder's displacement. Therefore, during an earthquake, the energy-dissipating components absorb the impact force between the main girder and the seismic-resistant structure, reducing shear damage to the piers and improving bridge safety.

[0030] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present application.

[0031] This application provides an embodiment of a bridge seismic-resistant structure with steel cable connection and its construction method, which can absorb the impact force between the main beam and the seismic-resistant structure during an earthquake, reduce the shear damage of the bridge piers, and improve the safety of the bridge.

[0032] Reference Figure 1 This application provides an embodiment of a bridge seismic isolation structure with steel cable connection, comprising a corbel 1, two cables 2, a connecting cable 3, and an energy dissipation component 4. The corbel 1 is cast into the bottom of a diaphragm 61 and integrally formed with the diaphragm 61. One end of each cable 2 is embedded in a cap beam 5, and the other ends of the two cables 2 are connected by the connecting cable 3 to prevent detachment. The connecting cable 3 passes through the corbel 1, and the energy dissipation component 4 is located at the connection between the cables 2 and the connecting cable 3. In the initial stage of movement of the main beam 6, both the cables 2 and the connecting cable 3 can move relative to the energy dissipation component 4, and the energy dissipation component 4 dissipates energy from the movement of the cables 2 and the connecting cable 3. When the movement of the main beam 6 causes the energy dissipation function of the energy dissipation component 4 to fail, the cables 2 tighten the connecting cable 3.

[0033] Furthermore, in combination Figure 2 and Figure 3 The energy-consuming component 4 includes a housing 41 and a pressing member 43. Specifically, the housing 41 has an open end, and two friction members 42 are disposed inside the housing 41. The ends of the cable 2 and the connecting cable 3 pass through the side wall of the housing 41 and are located between the two friction members 42. The pressing member 43 is connected to the open end of the housing 41 and is used to press the two friction members 42, thereby causing the two friction members 42 to create resistance to the movement of the cable 2 and the connecting cable 3 relative to the housing 41.

[0034] When construction workers install the energy-dissipating component 4 at the connection point of the cable 2 and the connecting cable 3, they first disconnect the clamping member 43 from the shell 41, insert one of the friction members 42 into the shell 41, then pass the ends of the cable 2 and the connecting cable 3 through the side wall of the shell 41, place the other friction member 42 inside the shell 41, and finally connect the clamping member 43 to the open end of the shell 41. The clamping member 43 compresses the friction member 42, and the two friction members 42 clamp the cable 2 and the connecting cable 3. When an earthquake occurs, in the initial stage of the main beam 6 moving, the cable 2 and the connecting cable 3 will move relative to the shell 41. The two friction members 42 resist the movement of the cable 2 and the connecting cable 3, thereby dissipating the energy of the impact force generated by the movement of the main beam 6. When the displacement of the main beam 6 is large, after the resistance of the two friction members 42 to the cable 2 and the connecting cable 3 fails, the cable 2 tightens the connecting cable 3.

[0035] Reference Figure 2 In a preferred embodiment of this application, the inner wall of the housing 41 is provided with internal threads, the outer wall of the extrusion member 43 is provided with external threads, and the top of the extrusion member 43 is provided with an internal hexagonal groove. When the construction worker connects the extrusion member 43 to the housing 41, an external hexagonal wrench is inserted into the internal hexagonal groove, and then the extrusion member 43 is screwed in, gradually screwing the extrusion member 43 into the housing 41, thereby compressing the two friction members 42. In this embodiment of the application, the friction members 42 can be made of rubber or other materials.

[0036] Furthermore, in combination Figure 2 and Figure 4 Two resistance sections 411 are arranged opposite each other at the open end of the housing 41. The pressing member 43 is connected to the two resistance sections 411. One of the resistance sections 411 is used to prevent the cable 2 from detaching from the housing 41, and the other resistance section 411 is used to prevent the connecting cable 3 from detaching from the housing 41. When the displacement of the main beam 6 causes the friction member 42 to fail in its obstruction of the cable 2 and the connecting cable 3, one of the resistance sections 411 comes into contact with the cable 2, and the other resistance section 411 comes into contact with the connecting cable 3. On the one hand, the resistance section 411 can, to a certain extent, hinder the continued movement of the cable 2 and the connecting cable 3; on the other hand, when the tension of the cable 2 and the connecting cable 3 is strong, the two resistance sections 411 are broken, thereby further dissipating the energy of the impact on the main beam 6.

[0037] Combination Figure 2 and Figure 4The cable 2 is folded in half to form two strands, and the two ends of the folded cable 2 are embedded in the cap beam 5. One of the resistance parts 411 is fitted onto the folded portion. The connecting cable 3 is formed by a steel cable looping around the cable, and the two ends of the steel cable can be fixed using conventional wire rope connectors. The end of the connecting cable 3 is chain-connected to the end of the cable 2 and fitted with another resistance part 411. Specifically, the open end of the housing 41 has four locking grooves 412 spaced apart along its circumference. The four locking grooves 412 are arranged in a cross shape, and the housing 41 between every two adjacent locking grooves 412 forms a resistance part 411, thus forming four resistance parts 411. Two opposing resistance parts 411 are selected to impede the movement of the cable 2 and the connecting cable 3.

[0038] When the construction workers connect the shell 41 and the cable 2, they select a resistance section 411 and press one strand of the cable 2 into the two locking grooves 412 on one side of the resistance section 411, and press the other strand of the cable 2 into the two locking grooves 412 on the other side of the resistance section 411. The bent part of the cable 2 is sleeved onto the resistance section 411. Using the same operation method, the end of the connecting cable 3 is sleeved onto the corresponding resistance section 411. In the initial stage of the main beam 6 movement, the two resistance sections 411 on both sides of the cable 2 and the connecting cable 3 can limit the movement of the cable 2 and the connecting cable 3, so that the cable 2 and the connecting cable 3 are always clamped by the two friction elements 42, thereby ensuring the good energy dissipation effect of the energy dissipation component 4. When the ends of cable 2 and connecting cable 3 come into contact with their corresponding resistance parts 411, as the main beam 6 moves, the ends of cable 2 and connecting cable 3 continuously squeeze the resistance parts 411 until the resistance parts 411 are crushed, thereby further consuming energy for the movement of the main beam 6.

[0039] In other embodiments, the connecting cable 3 can also be formed from a single steel cable. The difference is that after the steel cable passes through the corbel 1, both ends of the cable are passed through the bent portions of the two tension cables 2. Then, the two ends of the cable are bent, and a wire rope connector is used to fix the ends of the cable to the main body of the cable, forming a loop at both ends to form the connecting cable 3. The ends of the connecting cable 3 are also chain-connected to the ends of the tension cables 2, and a resistance part 411 can also be fitted onto the ends of the connecting cable 3.

[0040] Furthermore, refer to Figure 2 The open end of the housing 41 is fitted with a collar 44 to prevent the resistance parts 411 from opening outwards. Specifically, the outer wall of the resistance parts 411 has external threads, and the inner wall of the collar 44 has internal threads. The collar 44 is threadedly connected to the outer walls of the four resistance parts 411. With this arrangement, the collar 44 can prevent the resistance parts 411 from opening outwards, making the connection between the extruder 43 and the resistance parts 411 more reliable.

[0041] Furthermore, refer to Figure 5 A through-tube 13 is embedded inside the bracket 1, and the connecting cable 3 passes through the through-tube 13 to the bracket 1. With this setting, the resistance is small when the construction workers thread the connecting cable 3, making the threading of the connecting cable 3 more convenient.

[0042] Furthermore, refer to Figure 5 A partition 14 is fixed inside the conduit 13. After the connecting cable 3 is threaded through the bracket 1, the partition 14 is located within the annular space of the connecting cable 3. With this arrangement, when workers thread the connecting cable 3, one end of a steel cable first passes through the conduit 13 from the upper layer of the partition 14, then through the bent portion of one side of the tension cable 2, then through the conduit 13 from the lower layer of the partition 14, through the bent portion of the other side of the tension cable 2, and finally the two ends of the steel cable are fixed to form the connecting cable 3. During the threading process, the steel cables on the upper and lower layers of the partition 14 do not contact each other, thus reducing the resistance during the threading of the connecting cable 3.

[0043] Furthermore, refer to Figure 5 and Figure 6 The corbel 1 comprises a concrete block 11 and reinforcing bars 12. The concrete block 11 and the transverse diaphragm 61 are cast integrally. The two ends of the reinforcing bars 12 are embedded in the transverse diaphragm 61 and connected to the reinforcing bars within the transverse diaphragm 61. The middle part of the reinforcing bars 12 is bent and embedded in the concrete block 11. A conduit 13 passes through the middle bend of the reinforcing bars 12, and a connecting cable 3 passes through the conduit 13 and through the concrete block 11. When the main beam 6 moves and the resistance section 411 is broken, the cable 2 tightens the connecting cable 3. The connecting cable 3 will cause some damage to the concrete block 11, thereby further dissipating seismic energy. After the concrete block 11 is damaged, because the connecting cable 3 passes through the middle bend of the reinforcing bars 12 and is connected to the reinforcing bars within the transverse diaphragm 61, the connecting cable 3 can still continue to tighten the main beam 6 through the reinforcing bars 12, preventing beam collapse.

[0044] To ensure the stability of the corbel 1, in a preferred embodiment of this application, multiple reinforcing ribs 12 are spaced apart along the transverse direction of the bridge. In addition, multiple transverse reinforcing ribs 15 are embedded at intervals within the concrete block 11, and each transverse reinforcing rib 15 is connected to multiple reinforcing ribs 12, thereby ensuring the lateral stability of the multiple reinforcing ribs 12.

[0045] It should be noted that the earthquake-resistant structure, through the above-described configuration, can correspond to the three levels of bridge seismic design: "no damage in minor earthquakes, repairable in moderate earthquakes, and no collapse in major earthquakes." In the event of a minor earthquake, the main beam 6 begins to move, and both the cables 2 and 3 move relative to the energy-dissipating component 4. The energy-dissipating component 4 dissipates the energy from the movement of the cables 2 and 3. At this time, the energy-dissipating component 4 is undamaged, and can continue to be used after readjusting the positions of the cables 2 and 3 relative to the energy-dissipating component 4. In the event of a moderate earthquake, the damage to the resistance section 411 consumes some seismic energy, and the damage to the concrete block 11 further consumes seismic energy. Depending on the damage to the resistance section 411 and the concrete block 11, the energy-dissipating component 4 can be replaced, or the concrete block 11 can be recast and the structure can continue to be used. During a major earthquake, the displacement of the main girder 6 is substantial. Because the cable 2 and connecting cable 3 are connected to prevent detachment, and the connecting cable 3 passes through the middle bend of the reinforcing rib 12, the cable 2 tightens the connecting cable 3, which in turn tightens the main girder 6 via the corbel 1, effectively limiting the displacement of the main girder 6. Therefore, during an earthquake, the energy-dissipating components and concrete blocks absorb the impact force between the main girder and the seismic-resistant structure, reducing shear failure of the piers, improving bridge safety, and demonstrating good economic efficiency.

[0046] To improve the seismic resistance of the main beam 6, multiple sets of seismic-resistant structures can be installed along the transverse direction of the bridge during actual construction, thereby ensuring a better seismic resistance effect.

[0047] This application also discloses an embodiment of a construction method for a seismic-resistant structure, which includes the following steps:

[0048] S1. Position the two cables 2, insert one end of the cable 2 into the formwork of the cap beam 5, and pour the concrete of the pier cap beam 5 in place.

[0049] S2. Set up the templates for corbel 1 and diaphragm 61. After the diaphragm 61 and corbel 1 are poured, remove the templates for corbel 1 and diaphragm 61.

[0050] S3. Connect the connecting cable 3 and the two tension cables 2 to prevent them from detaching, so that the connecting cable 3 passes through the bracket 1 and ensures that the connecting cable 3 and the tension cables 2 have a certain amount of relative displacement.

[0051] S4. Install energy dissipation component 4 at the connection point of connecting cable 3 and cable 2.

[0052] Furthermore, before positioning the two cables 2 in step S1, the procedure includes folding each cable 2 in half, placing the two ends formed by the fold inside the cap beam 5, and allowing the bent portion to extend out of the cap beam 5. In step S3, the connecting cable 3 and the cables 2 are connected to prevent detachment. The specific steps for the connecting cable 3 to pass through the corbel 1 are as follows: one end of a steel cable is first passed through the bent portion of the steel cable between the corbel 1 and one side of the cap beam 5, then it meanders through the steel cable between the corbel 1 and the other side of the cap beam 5, and finally, both ends of the steel cable are fixed to form the connecting cable 3.

[0053] For step S2, before setting the formwork for the corbel 1 and the transverse diaphragm 61, the following steps are included: binding the reinforcing bars 12 and the reinforcing bars of the transverse diaphragm 61, positioning the conduit 13, and preparing for setting the formwork. Therefore, in step S3, the steel cables all pass through the corbel 1 via the conduit 13.

[0054] For step S4, the specific steps are as follows: First, place a friction element 42 inside the housing 41. Select a resistance section 411, press one strand of the cable 2 into the two locking grooves 412 on one side of the resistance section 411, and press the other strand of the cable 2 into the two locking grooves 412 on the other side of the resistance section 411, so that the bent part of the cable 2 fits against the resistance section 411. Using the same operation method, fit the end of the connecting cable 3 onto the opposite resistance section 411. Then, place another friction element 42 inside the housing 41, screw the pressing element 43 into the housing 41, so that the two friction elements 42 press against the cable 2 and the connecting cable 3, and finally screw the collar 44 into the open end of the housing 41.
