Description

Technical Field

[0001] This utility model relates to the field of laminated rubber bearing technology, and in particular to a laminated rubber bearing that is easy to install and fix. Background Technology

[0002] Laminated rubber bearings are a type of seismic isolation and damping device widely used in building structures, bridge engineering, and other fields. Their core structure consists of multiple layers of rubber material and steel plates alternately laminated and vulcanized. The rubber layers, with their excellent elastic deformation capacity, effectively absorb and dissipate external vibration energy; the steel plate layers provide horizontal stiffness and vertical bearing capacity, ensuring stable mechanical properties of the bearing under load. This composite structural design gives laminated rubber bearings both flexible deformation characteristics and sufficient load-bearing capacity. Under dynamic loads such as earthquakes, they can extend the natural period of the structure through their own horizontal shear deformation, reducing the transmission of seismic energy to the upper structure, thereby reducing the risk of seismic damage to buildings. They are a key component in modern engineering structures for achieving seismic isolation and damping functions.

[0003] However, existing methods for installing and fixing laminated rubber bearings generally suffer from insufficient convenience. Traditional bearings are mostly connected to the upper and lower structures by pre-embedded bolts or welding, requiring precise alignment and heavy equipment assistance during installation, which is extremely inconvenient, especially in confined spaces or at heights. Replacement requires damage to the original structure, leading to extended construction periods and increased maintenance costs. The overall positioning and fixing capabilities are relatively poor, affecting installation convenience in the event of vibration accidents and increasing the overall operational difficulty. Furthermore, the overall device lacks precise positioning and anti-tilting capabilities, which may cause loosening and tilting at the installation end due to vibration or other unexpected situations. The anti-tilting reinforcement capability is also generally limited. Therefore, we propose a laminated rubber bearing that is easy to install and fix to solve the above problems.

Two annular fixing gaskets are correspondingly bolted and fixed to the upper and lower ends of the multiple bolted fixing members.

[0009] Preferably, the plurality of U-shaped fixing seats and anti-slip fixing pads are evenly distributed in a ring shape with the center of the laminated rubber support body as the axis, and the ring fixing pads are on the same axis as the laminated rubber support body.

[0010] Preferably, the auxiliary fixing component includes a cross mounting bracket, a cross mounting opening, riveting reinforcement holes, and riveting fasteners.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Please see Figures 1-6 A composite rubber support that is easy to install and fix includes a composite rubber support body 1, and pre-embedded installation components 2 are fixedly installed on both the upper and lower sides of the composite rubber support body 1. Two pre-embedded installation components 2 are provided with installation limit ports 3 on opposite sides. Limiting and fixing seats 4 that are engaged and fixed to the installation limit ports 3 are installed on the flanges on the upper and lower sides of the laminated rubber support body 1. Assembling and fixing components 5 that are fixed to the upper and lower flanges of the laminated rubber support body 1 are installed on the edges of the two pre-embedded installation components 2. Among them, an auxiliary fixing part 6 that engages with the limiting fixing seat 4 is installed in the installation limiting port 3; The beneficial effects of this solution are as follows: By pre-embedding the installation components 2 on the upper and lower sides of the part to be assembled, the main body 1 of the laminated rubber bearing can be installed between the two pre-embedding installation components 2. When the main body 1 of the laminated rubber bearing is installed and fixed, it can be positioned in the installation limit port 3 by the insertion of the limit fixing seat 4 to complete the anti-displacement fixing operation. The auxiliary fixing component 6 assists in the anti-displacement fixing bolt connection of the installation limit port 3 and the limit fixing seat 4. The installation is tight and the precise alignment after installation facilitates the installation and fixing of the assembly fixing component 5. The assembly fixing component 5 is a multi-bolt integrated installation on the main body 1 of the laminated rubber bearing and the pre-embedding installation components 2, so that the bolting fixing method is changed from single-point fixing to overall fixing. The installation tightness is high, the overall seismic and anti-tilting ability is strong, the device has a good anti-displacement positioning and fixing effect, facilitates the later installation and disassembly, and has excellent precise positioning and anti-tilting ability and high shock absorption resistance.

[0019] Furthermore, both pre-embedded installation components 2 include a disassembly flange plate 21, a pre-embedded fixing bracket 22, and a support fixing seat 23. The two support fixing seats 23 are fixedly installed on opposite sides of the two disassembly flange plates 21, and multiple pre-embedded fixing brackets 22 are correspondingly installed on opposite sides of the two support fixing seats 23. The support fixing seats 23 are located between adjacent disassembly flange plates 21 and pre-embedded fixing brackets 22. The disassembly flange plates 21, pre-embedded fixing brackets 22, and support fixing seats 23 are welded and assembled into one piece. The installation limiting port 3 is correspondingly opened on the disassembly flange plates 21 and the support fixing seats 23. Specifically, the pre-embedded installation components 2 all include a detachable flange plate 21, a pre-embedded fixing bracket 22, and a support fixing seat 23. The detachable flange plate 21 and the support fixing seat 23 can be formed as a whole, which facilitates the opening of the installation limit port 3. The other end can be pre-embedded and fixed by the pre-embedded fixing bracket 22. The fixing is stable, and the pre-embedded tightness and strength are high. The detachable flange plate 21 can be installed and fixed with the flange of the laminated rubber support body 1, and the installation adaptability is good.

[0020] Furthermore, both the installation limiting port 3 and the limiting fixing seat 4 are rectangular in shape. The limiting fixing seat 4 is fitted and inserted into the inner side of the installation limiting port 3. The gap between the pre-embedded installation component 2 and the laminated rubber support body 1 is filled and fixed with anti-slip pads 41. Specifically, both the installation limiting port 3 and the limiting fixing seat 4 are rectangular. When the laminated rubber support body 1 is installed and fixed, it can be inserted and positioned in the installation limiting port 3 by the limiting fixing seat 4 to complete the anti-displacement fixing operation. The anti-displacement tightness is good. The setting of the anti-slip pad 41 makes the pre-embedded installation component 2 and the laminated rubber support body 1 fit stably when tightly installed as one, with excellent installation tightness and good anti-slip, anti-vibration and anti-loosening capabilities.

[0021] Furthermore, the assembly and fixing component 5 includes a U-shaped fixing seat 51, a bolted fixing component 52, and an annular fixing gasket 53. Multiple U-shaped fixing seats 51 are annularly clamped between the pre-embedded installation component 2 and the laminated rubber support body 1. The bolted fixing component 52 is inserted into the middle of the U-shaped fixing seat 51. The upper and lower sides of the bolted fixing component 52 are bolted and fixed to the pre-embedded installation component 2 and the laminated rubber support body 1, respectively. Anti-slip fixing gaskets 54 are provided at both the upper and lower ends of the bolted fixing component 52. The anti-slip fixing gaskets 54 are located on the side of the pre-embedded installation component 2 and the laminated rubber support body 1 that are far away from each other. Two annular fixing gaskets 53 are bolted and fixed to the upper and lower ends of the multiple bolted fixing components 52, respectively. Specifically, the bolted fastener 52 can bolt the flange plate of the pre-embedded installation component 2 and the laminated rubber support body 1 together. The U-shaped fixing seat 51 plays a role in padding and fixing. Multiple U-shaped fixing seats 51 and bolted fasteners 52 are distributed in a ring, resulting in high installation tightness. The annular fixing gasket 53 is bolted to the upper and lower sides of multiple bolted fasteners 52, which strengthens the fixing and prevents displacement and loosening of multiple U-shaped fixing seats 51 and bolted fasteners 52. This changes the bolted fixing method from single-point fixing to overall fixing, increasing the installation tightness, strengthening the overall seismic and anti-tilting ability, and making it less prone to loosening. The anti-slip fixing gasket 54 is installed between the annular fixing gasket 53 and the bolted fastener 52, further playing a role in preventing loosening and fixing. The integrated installation has high strength.

[0022] Furthermore, multiple U-shaped fixing seats 51 and anti-slip fixing pads 54 are evenly distributed in a ring shape with the center of the laminated rubber support body 1 as the axis, and the ring fixing pads 53 are on the same axis as the laminated rubber support body 1. Specifically, multiple U-shaped fixing seats 51 and anti-slip fixing pads 54 are evenly distributed in a ring shape with the center of the laminated rubber support body 1 as the axis. They are tightly installed and have excellent adaptability. The U-shaped fixing seats 51, bolt fasteners 52 and anti-slip fixing pads 54 are fixed as a whole by two ring fixing pads 53, and the overall tightness is excellent.

[0023] Furthermore, the auxiliary fastener 6 includes a cross mounting bracket 61, a cross mounting opening 62, a riveting reinforcement hole 63, and a riveting fastener 64. The cross mounting bracket 61 is installed inside the mounting limit opening 3.

The cross mounting bracket 61 is inserted and fixed inside the cross mounting opening 62. The riveting reinforcement hole 63 is correspondingly opened on the outside of the limit fixing seat 4 and the pre-embedded mounting component 2. The riveting fastener 64 is riveted into the two opposite riveting reinforcement holes 63. The riveting fastener 64 is bolted and fixed to the limit fixing seat 4 and the pre-embedded mounting component 2. Specifically, the auxiliary fixing component 6 includes a cross mounting bracket 61, a cross mounting port 62, a riveting reinforcement hole 63, and a riveting fixing component 64. When the limiting fixing seat 4 is inserted and positioned within the installation limiting port 3, it can be correspondingly sleeved and engaged with the cross mounting bracket 61 by the cross mounting port 62, further improving the anti-offset adaptability of the device installation and ensuring high anti-offset accuracy. The riveting reinforcement hole 63 is correspondingly opened on the outside of the limiting fixing seat 4 and the pre-embedded mounting component 2. When the limiting fixing seat 4 is inserted and positioned within the installation limiting port 3, adjacent riveting reinforcement holes 63 are aligned with each other and can be riveted and fixed by the riveting fixing component 64. Multiple riveting fixing components 64 can be evenly installed on the outside of the pre-embedded mounting component 2 and the limiting fixing seat 4, making riveting installation convenient, improving the installation tightness and anti-offset capability, and fixing the whole into a whole, making it difficult to tilt or fall off, and providing a good anti-offset fixing effect.

[0024] Furthermore, the riveting reinforcement holes 63 and the riveting fasteners 64 are evenly distributed in a ring shape on the outer side of the limiting fixing seat 4 and the pre-embedded mounting component 2, and the riveting fasteners 64 are made of galvanized material. Specifically, the riveting reinforcement holes 63 and the riveting fasteners 64 are evenly distributed in a ring shape on the outer side of the limiting fixing seat 4 and the pre-embedded installation component 2. The overall installation is evenly stressed and has excellent adaptability. The riveting fasteners 64 are made of galvanized material, which has good corrosion resistance and durability.

[0025] How to use and how to work this device: By setting up the laminated rubber bearing body 1, it can be installed and supported in the shock-absorbing support part of the bridge and building structure. It plays a shock-absorbing and protective role through its own horizontal shear deformation. The upper and lower sides of the laminated rubber bearing body 1 are respectively installed with pre-embedded installation components 2. The pre-embedded installation components 2 are pre-embedded and installed on the upper and lower sides of the part to be assembled, so that the laminated rubber bearing body 1 can be installed between the two pre-embedded installation components 2 for fixed installation. Two pre-embedded installation components 2 are provided with installation limit ports 3 on opposite sides, and two laminated rubber support bodies 1 are provided with limit fixing seats 4 on their upper and lower sides. When the laminated rubber support body 1 is installed and fixed, it can be positioned in the installation limit port 3 by the limit fixing seat 4 to complete the anti-displacement fixing operation. After the assembly is completed, the auxiliary fixing parts 6 can be used to help to fix the installation limit port 3 and the limit fixing seat 4 to prevent displacement. The installation is tight and it is not easy to tilt or shift due to vibration and torsion. After precise alignment and installation, it is convenient to install and fix the assembly and fixing components 5. The assembly and fixing component 5 includes a U-shaped fixing seat 51, a bolted fixing component 52, and an annular fixing gasket 53.
