Description

Technical Field

[0001] This utility model relates to the field of bridge bearing technology, specifically an integral adjustable height seismic isolation rubber bearing and its installation and replacement structure. Background Technology

[0002] Plate rubber bearings are the most widely used type of bridge bearing, but they also suffer from the most defects. Seismic isolation rubber bearings have solved problems such as voids and excessive shear instability associated with plate bearings. However, natural rubber bearings, high-damping rubber bearings, and lead-core rubber bearings generally require sealing and grouting of the bottom surface during installation. Before replacing the original bearing, part of the mortar layer needs to be removed, and a second grouting is required after the new bearing is installed, which is labor-intensive and time-consuming. Adjusting or replacing the bearing requires removing all bolts, but due to space constraints, the bolts on the inside of the bearing are difficult to remove, necessitating permanent damage such as cutting the original structure, making replacement difficult. Therefore, traditional seismic isolation rubber bearings present challenges such as difficulty in adjusting and replacing them.

[0003] In the existing technology, the problem of difficulty in adjusting the bearing height and replacing the seismic isolation rubber is solved by using a segmented enclosure composed of multiple enclosure connectors. However, this brings new technical problems: the segmented enclosure has many connectors and its overall mechanical performance is somewhat lacking. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an integral height-adjustable vibration-damping rubber bearing for enclosures and its installation and replacement structure.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] like Figures 1 to 3 As shown, an integral adjustable height vibration isolation rubber bearing for fencing is characterized by comprising: an upper fencing assembly, a lower fencing assembly, a bearing body, and an adjustable height pad, wherein the bearing body is composed of stiffening steel plates and rubber, and is used for vibration isolation;

[0007] The upper enclosure assembly consists of an upper enclosure, an upper anchor steel bar, and an upper anchor bolt. The upper anchor bolt passes upward through the upper enclosure and is threadedly connected to the upper anchor steel bar. The lower enclosure assembly consists of a lower enclosure, a lower anchor steel bar, and a lower anchor bolt. The lower anchor bolt passes downward through the lower enclosure and is threadedly connected to the lower anchor steel bar.

[0008] Both the upper and lower enclosures are integral enclosures, with the top and bottom of the support body respectively embedded in the limiting through holes of the upper enclosure and the lower enclosure; thus, the upper and lower enclosures restrict the horizontal movement of the support body.

[0009] At least one of the limiting through holes of the upper and lower enclosures is embedded with the height adjustment pad, and the height adjustment pad is in close contact with the support body. Thus, the height can be adjusted by the height adjustment pad, and the horizontal movement of the height adjustment pad can be restricted by the upper or lower enclosure.

[0010] The cross-sections of the support body, the height adjustment pad, the limiting through holes of the upper enclosure, and the lower enclosure are preferably matched in shape and size so that their sidewalls can fully abut; however, only abutment at a few points is also acceptable, as long as it is ensured that the horizontal movement of the support body and the height adjustment pad can be restricted.

[0011] Preferably, the upper anchor steel bar is composed of an upper sleeve and an upper anchor rod connected together, and the upper anchor bolt passes upward through the upper enclosure and is threadedly connected to the upper sleeve; the lower anchor steel bar is composed of a lower sleeve and a lower anchor rod connected together, and the lower anchor bolt passes downward through the lower enclosure and is threadedly connected to the lower sleeve.

[0012] This enhances the anchoring capacity of both the upper and lower anchor bars.

[0013] Preferably, the height adjustment pad is composed of one or more pads stacked together, so that the required thickness of the height adjustment pad can be easily obtained by adjusting the number of pads; however, a single pad of the required thickness can also be directly selected.

[0014] Preferably, when the limiting through hole of the upper enclosure is embedded with an adjusting pad, an adjusting plate is fixed on the top surface of the upper enclosure to provide a horizontal surface during installation.

[0015] Preferably, both the upper and lower enclosures are rectangular frames. The upper enclosure assembly has four sets of upper anchor steel bars and upper anchor bolts distributed at the four corners of the rectangular frame, and the lower enclosure assembly has four sets of lower anchor steel bars and lower anchor bolts distributed at the four corners of the rectangular frame.

[0016] In addition, the shape of the upper and lower enclosures and the shape of their limiting through holes, as well as the number of upper anchor steel bars and upper anchor bolts, lower anchor steel bars and lower anchor bolts, can all be set as needed. For example, the upper and lower enclosures and their limiting through holes can be set to shapes such as outer circle inside square, outer square inside circle, outer circle inside circle, and outer square inside square.

[0017] like Figure 6 As shown, an installation structure for an adjustable height seismic isolation rubber bearing for an integral enclosure is characterized by comprising: the adjustable height seismic isolation rubber bearing for the integral enclosure and a pad stone, used to install the adjustable height seismic isolation rubber bearing for the integral enclosure between the base and the beam.

[0018] The pad stones are fixedly installed on the top surface of the base, and a reserved hole is reserved for each lower anchor steel bar, which consists of a through hole on the pad stone and a blind hole on the top surface of the base.

[0019] The lower anchor steel bar is placed in the corresponding reserved hole and anchored in the reserved hole by the high-strength mortar poured in. The lower retaining wall is placed on the top surface of the pad stone, and the lower anchor bolt passes downward through the lower retaining wall and is threadedly connected to the lower anchor steel bar to form the lower retaining wall assembly. Furthermore, the bottom of the support body is embedded in the limiting through hole of the lower retaining wall.

[0020] The upper enclosure, upper anchor steel bar, and upper anchor bolts are connected to form the upper enclosure assembly. The top of the support body is embedded in the limiting through hole of the upper enclosure, and the upper anchor steel bar is anchored in the beam.

[0021] At least one of the limiting through holes of the upper enclosure and the lower enclosure is embedded with the height adjustment pad to achieve height adjustment, so that the height adjustment pad is tightly abutted against the support body and clamped between the base and the beam, ensuring that the base supports the beam through the integral enclosure adjustable vibration isolation rubber bearing.

[0022] Therefore, this utility model adopts an integral enclosure as the upper and lower enclosures. Compared with the segmented enclosures used in the prior art, on the one hand, it improves the horizontal stress performance of the support, so that all the anchoring connectors of the support generate resistance at the same time, thereby reducing the possibility of node cracking and improving the safety and reliability of the structure. On the other hand, it reduces the number of connectors used, which can save material usage and reduce production costs.

[0023] Furthermore, the installation structure adopted by this utility model allows the integral fence to still be disassembled and adjusted in height using height adjustment pads, without reducing the convenience of height adjustment and pad replacement.

[0024] The installation structure of the integrated adjustable height seismic isolation rubber bearing for the enclosure described in this utility model has the following construction steps:

[0025] Step S1, see Figure 4 The pad stone is fixed on the top surface of the base, and a reserved hole is reserved for each lower anchor steel bar, which is composed of a through hole on the pad stone and a blind hole on the top surface of the base; wherein, the outer diameter of the reserved hole is preferably the outer diameter of the lower anchor steel bar plus 60mm, and the depth of the reserved hole is preferably the length of the lower anchor steel bar plus 50mm.

[0026] Step S2, see Figure 5The lower anchor steel bar is placed in the corresponding reserved hole, and high-strength mortar is injected into the reserved hole using gravity grouting or pressure grouting to anchor the lower anchor steel bar in the reserved hole; after the mortar reaches the design strength, the center position and elevation of the support are checked again, and then the lower retaining wall is placed on the top surface of the pad stone, and the lower anchor bolts are threaded down through the lower retaining wall and connected to the lower anchor steel bar to form the lower retaining wall assembly, thereby fixing it on the base; the pad stone is used to increase the stability of the lower retaining wall assembly on the base;

[0027] Furthermore, the bottom of the support body is embedded in the limiting through hole of the lower enclosure.

[0028] Step S3, see Figure 6 First, the upper enclosure, the upper anchor steel bar, and the upper anchor bolt are connected to form the upper enclosure assembly. Then, the top of the support body is embedded into the limiting through hole of the upper enclosure. Finally, the upper anchor steel bar is anchored in the beam to fix the upper enclosure assembly to the beam.

[0029] In cases where the adjustable height isolation rubber bearing of the integral enclosure is equipped with an adjustable plate, a pad can be used to temporarily support the beam at the center below to prevent the adjustable plate from bending and deforming downwards due to its low bending stiffness.

[0030] Step S4: At least one of the limiting through holes of the upper enclosure and the lower enclosure is embedded with the height adjustment pad to achieve height adjustment, so that the height adjustment pad is tightly abutted against the support body and clamped between the base and the beam, ensuring that the base supports the beam through the integral enclosure adjustable vibration isolation rubber support.

[0031] Taking the installation of the height adjustment shim in the limiting through hole of the upper enclosure as an example, the specific height adjustment steps are as follows:

[0032] Step S4-1, see Figure 7 First, use jacks and other auxiliary components to support the beam; then unscrew the upper anchor bolts to remove the upper enclosure from the upper anchor steel bar and the beam, and move it downward along the support body through the limiting through hole of the upper enclosure to expose the gap between the support body and the beam.

[0033] Step S4-2, see Figure 8 First, use jacks to lift the beam to the required height; then, according to the gap between the support body and the beam, insert an adjustable shim of the required thickness between the support body and the beam to adjust the support height, so that the adjustable shim is tightly against the support body and clamped between the base and the beam, ensuring that the base supports the beam through the integral adjustable vibration isolation rubber bearing.

[0034] Step S4-3, see Figure 9Reset the upper enclosure and retighten the upper anchor bolts. Apply sealant while screwing in the bolts, and after tightening, apply a coat of epoxy zinc-rich primer to the bolt heads. Then, unload the jacks and lower the beam.

[0035] The beam is a cast-in-place concrete beam, and the upper anchor steel bar is embedded in the cast-in-place concrete beam during the pouring process.

[0036] The beam is a precast concrete beam, and the upper anchor steel bar is embedded in the precast concrete beam.

[0037] The beam is a steel beam or a steel-concrete composite beam, and the upper anchor bolts are connected to the reserved threaded holes on the bottom surface of the beam, without the need for the upper anchor steel bars.

[0038] like Figure 10 As shown, a replacement structure for an adjustable height seismic isolation rubber bearing for an integral enclosure is characterized by comprising: an installation structure for the adjustable height seismic isolation rubber bearing for the integral enclosure, a hand-operated hoist, a thin support plate, and an installation platform.

[0039] The hand-operated hoist and the mounting platform are respectively installed on both sides of the pad stone, with the top surface of the mounting platform flush with the top surface of the pad stone, allowing the thin support plate to slide horizontally on the top surfaces of the mounting platform and the pad stone. The mounting platform should be strong enough to support the weight of the support body.

[0040] Using the aforementioned replacement structure, this utility model can replace the adjustable height vibration isolation rubber support of the integral enclosure through the following steps:

[0041] First, use jacks to support beam 19;

[0042] Then, the old integrated fence adjustable height vibration isolation rubber bearings are disassembled. Among them, the old bearing body and the upper and lower fence components can be easily and effortlessly pulled by a hand chain hoist with a soft rope, and pulled outward until the crane can lift the bearing body.

[0043] Finally, install and replace the new integrated adjustable height seismic isolation rubber bearing for the enclosure. The process involves placing the new bearing body on a thin support plate and using a hand chain hoist with a soft rope to easily and effortlessly pull the thin support plate, preventing excessive friction between the installation platform and the pad stone. This moves the new bearing body to the predetermined installation position. Then, block the bearing body and remove the thin support plate, making slight adjustments to the bearing body to the precise position. The installation of the new integrated adjustable height seismic isolation rubber bearing for the enclosure is then completed according to the above description.

[0044] Therefore, the replacement structure of this utility model can conveniently and effortlessly replace the adjustable height vibration isolation rubber bearing of the integral enclosure.

[0045] Compared with the prior art, the present invention has the following beneficial effects:

[0046] First, this utility model adopts an integral enclosure as the upper enclosure 111 and the lower enclosure 121. Compared with the segmented enclosure used in the prior art, on the one hand, it improves the horizontal force performance of the support, so that all the anchoring connectors of the support generate resistance at the same time, thereby reducing the possibility of node cracking and improving the safety and reliability of the structure. On the other hand, it reduces the number of connectors used, which can save material usage and reduce production costs.

[0047] Furthermore, the installation structure adopted by this utility model allows the integral fence to still be disassembled and adjusted in height using the height adjustment pad 14, without reducing the convenience of height adjustment and pad replacement.

[0048] Secondly, the replacement structure of this utility model can conveniently and effortlessly replace the adjustable height vibration isolation rubber support 10 of the integral enclosure. Attached Figure Description

[0064] Both the upper enclosure 111 and the lower enclosure 121 are integral enclosures. The top and bottom of the support body 13 are respectively embedded in the limiting through hole 111a of the upper enclosure 111 and the limiting through hole 121a of the lower enclosure 121. Thus, the upper enclosure 111 and the lower enclosure 121 restrict the horizontal movement of the support body 13.

Thus, the height can be adjusted by the height adjustment pad 14, and the horizontal movement of the height adjustment pad 14 can be restricted by the upper enclosure 111 or the lower enclosure 121.

[0066] The cross-sections of the support body 13, the height adjustment pad 14, the limiting through hole 111a of the upper enclosure 111, and the limiting through hole 121a of the lower enclosure 121 are preferably matched in shape and size so that their sidewalls can fully abut; however, only abutment at a few points is also possible, as long as it is ensured that the horizontal movement of the support body 13 and the height adjustment pad 14 can be restricted.

[0067] The above is the basic implementation method of this embodiment one, and further optimizations, improvements and limitations can be made based on this basic implementation method:

[0069] This enhances the anchoring capability of the upper anchor steel bar 112 and the lower anchor steel bar 122.

[0070] Preferably, the height adjustment pad 14 is composed of one or more pads stacked together, so that the required thickness of the height adjustment pad 14 can be easily obtained by adjusting the number of pads; however, a single pad of the required thickness can also be directly selected.

[0071] Preferably, when the limiting through hole 111a of the upper enclosure 111 is embedded with the height adjustment pad 14, the top surface of the upper enclosure 111 is fixed with an adjustment plate 15 to provide a horizontal surface during installation.

[0072] Preferably, both the upper enclosure 111 and the lower enclosure 121 are rectangular frames.

For example, the upper enclosure 111 and the lower enclosure 121 and their limiting through holes can be set to shapes such as outer circle inside square, outer square inside circle, outer circle inside circle, and outer square inside square.

[0074] Example 2

[0075] like Figure 6 As shown, Embodiment 2 of this utility model discloses an installation structure for an integral adjustable height seismic isolation rubber bearing, including: the integral adjustable height seismic isolation rubber bearing 10 described in Embodiment 1 and a pad stone 40, used to install the integral adjustable height seismic isolation rubber bearing 10 between the base 20 and the beam 30.

[0076] The pad stone 40 is fixedly installed on the top surface of the base 20, and a reserved hole 40a is reserved for each lower anchor steel bar 122, which is composed of a through hole on the pad stone 40 and a blind hole on the top surface of the base 20.

[0077] The lower anchor steel bar 122 is placed in the corresponding reserved hole 40a and anchored in the reserved hole 40a by the high-strength mortar 50 poured in. The lower enclosure 121 is placed on the top surface of the pad stone 40, and the lower anchor bolt 123 passes downward through the lower enclosure 121 and is threadedly connected to the lower anchor steel bar 122 to form the lower enclosure assembly 12. Furthermore, the bottom of the support body 13 is embedded in the limiting through hole 121a of the lower enclosure 121.

[0078] The upper enclosure 111, the upper anchor steel bar 112 and the upper anchor bolt 113 are connected to form the upper enclosure assembly 11. The top of the support body 13 is embedded in the limiting through hole 111a of the upper enclosure 111, and the upper anchor steel bar 112 is anchored in the beam 30.

[0079] At least one of the limiting through hole 111a of the upper enclosure 111 and the limiting through hole 121a of the lower enclosure 121 is embedded with the height adjustment pad 14 to achieve height adjustment, so that the height adjustment pad 14 is tightly abutted against the support body 13 and clamped between the base 20 and the beam 30, ensuring that the base 20 supports the beam 30 through the integral enclosure adjustable height isolation rubber support 10.

[0080] Therefore, this utility model adopts an integral enclosure as the upper enclosure 111 and the lower enclosure 121. Compared with the segmented enclosure used in the prior art, on the one hand, it improves the horizontal stress performance of the support, so that all the anchoring connectors of the support generate resistance at the same time, thereby reducing the possibility of node cracking and improving the safety and reliability of the structure. On the other hand, it reduces the number of connectors used, which can save material usage and reduce production costs.

[0081] Furthermore, the installation structure adopted by this utility model allows the integral fence to still be disassembled and adjusted in height using the height adjustment pad 14, without reducing the convenience of height adjustment and pad replacement.

[0082] The installation structure of the integrated adjustable height seismic isolation rubber bearing for the enclosure described in this utility model has the following construction steps:

[0083] Step S1, see Figure 4 The pad stone 40 is fixedly set on the top surface of the base 20, and a reserved hole 40a is reserved for each lower anchor steel bar 122, which is composed of a through hole on the pad stone 40 and a blind hole on the top surface of the base 20; wherein, the outer diameter of the reserved hole 40a is preferably the outer diameter of the lower anchor steel bar 122 plus 60mm, and the depth of the reserved hole 40a is preferably the length of the lower anchor steel bar 122 plus 50mm.

[0084] Step S2, see Figure 5 The lower anchor steel bar 122 is placed in the corresponding reserved hole 40a, and high-strength mortar 50 is injected into the reserved hole 40a by gravity grouting or pressure grouting, so that the lower anchor steel bar 122 is anchored in the reserved hole 40a; after the mortar reaches the design strength, the center position and elevation of the support are checked again, and then the lower enclosure 121 is placed on the top surface of the pad stone 40, and the lower anchor bolt 123 is threaded through the lower enclosure 121 and threaded to the lower anchor steel bar 122 to form the lower enclosure assembly 12, so as to realize its fixation on the base 20; wherein, the pad stone 40 is used to increase the stability of the lower enclosure assembly 12 on the base 20;

[0086] Step S3, see Figure 6 First, the upper enclosure 111, the upper anchor steel bar 112, and the upper anchor bolt 113 are connected to form the upper enclosure assembly 11. The top of the support body 13 is then embedded into the limiting through hole 111a of the upper enclosure 111. The upper anchor steel bar 112 is then anchored in the beam 30 to fix the upper enclosure assembly 11 to the beam 30.

[0087] In cases where the adjustable height isolation rubber bearing 10 of the integral enclosure is equipped with an adjustable plate 15, a pad can be used to temporarily support the beam 30 at the center below to prevent the adjustable plate 15 from bending and deforming downwards due to its low bending stiffness.

[0088] Step S4: At least one of the limiting through holes 111a of the upper enclosure 111 and the limiting through holes 121a of the lower enclosure 121 is embedded with the height adjustment pad 14 to achieve height adjustment, so that the height adjustment pad 14 is tightly abutted against the support body 13 and clamped between the base 20 and the beam 30, ensuring that the base 20 supports the beam 30 through the integral enclosure adjustable height isolation rubber support 10.

[0089] Taking the setting of the height adjustment plate 14 in the limiting through hole 111a of the upper enclosure 111 as an example, the specific height adjustment steps are as follows:

[0090] Step S4-1, see Figure 7 First, use jacks and other auxiliary components to support the beam 30; then unscrew the upper anchor bolts 113 to remove the upper enclosure 111 from the upper anchor steel bar 112 and the beam 30, and move it downward along the support body 13 through the limiting through hole 111a of the upper enclosure 111 to expose the gap between the support body 13 and the beam 30.

[0091] Step S4-2, see Figure 8First, use a jack to lift the beam 30 to the required height; then, according to the gap height between the support body 13 and the beam 30, insert an adjustable shim 14 of the required thickness between the support body 13 and the beam 30 to adjust the support height, so that the adjustable shim 14 and the support body 13 are tightly abutted and clamped between the base 20 and the beam 30, ensuring that the base 20 supports the beam 30 through the integral adjustable height isolation rubber bearing 10.

[0092] Step S4-3, see Figure 9 Reset the upper enclosure 111 and retighten the upper anchor bolts 113. Apply sealant when screwing in the bolts, and after tightening, apply a coat of epoxy zinc-rich primer to the bolt heads. Then, unload the jacks and lower the beam 30.

[0093] The above is the basic implementation method of this embodiment two, and further optimizations, improvements and limitations can be made based on this basic implementation method:

[0094] The beam 30 is a cast-in-place concrete beam, and the upper anchor steel bar 112 is embedded in it during the casting of the cast-in-place concrete beam.

[0095] The beam 30 is a precast concrete beam, and the upper anchor steel bar 112 is embedded in the precast concrete beam.

[0096] The beam 30 is a steel beam or a steel-concrete composite beam. The upper anchor bolt 113 is connected to the reserved threaded hole on the bottom surface of the beam 30, and there is no need to install the upper anchor steel bar 112.

The mounting platform 80 should be strong enough to support the weight of the support body 13.

[0100] Using the aforementioned replacement structure, this utility model can replace the adjustable height vibration isolation rubber support 10 of the integral enclosure through the following steps:

[0101] First, use jacks to support beam 19;

[0102] Then, the old integrated fence adjustable height vibration isolation rubber bearing 10 is disassembled.

This moves the new bearing body 13 to the predetermined installation position. Then, the bearing body 13 is blocked and the thin support plate 70 is pulled out. The bearing body 13 is slightly adjusted to the precise position. The installation of the new integrated adjustable height seismic isolation rubber bearing 10 is completed as described above.

[0104] Therefore, the replacement structure of this utility model can conveniently and effortlessly replace the adjustable height vibration isolation rubber support 10 of the integral enclosure.
