Overview
Principles of Construction
Rubber plate expansion device is a device that uses the elasticity of rubber material to adapt to the expansion and contraction deformation of bridges or buildings caused by temperature changes, load effects, and other factors.
The rubber plate expansion device is mainly composed of rubber, steel plate or angle steel vulcanized into one structure, and its expansion body is equipped with upper and lower grooves. The rubber body is embedded with load-bearing steel plates and anchoring steel plates, which are connected to the beam end as a whole through bolts. When a bridge or building undergoes expansion and contraction deformation, the rubber body will undergo shear deformation to meet the relative displacement requirements of the beam structure.
This device has the following characteristics:
Good elasticity: Rubber materials have strong elasticity and can adapt well to the deformation of bridges, ensuring the smoothness of vehicle travel.
Superior waterproof performance: Adhesive is poured into the bolt holes at the bottom of the expansion joint and every meter of assembly, effectively preventing rainwater, garbage, soil, and other debris from infiltrating and blocking the expansion device, ensuring the durability of the bridge.
Outstanding wear resistance and aging resistance: able to withstand the repeated loads of vehicles, it remains as tough as ever after the test of time, improving the service life of expansion joints.
Economical and easy to install: segmented assembly, bolt connection, simple and fast installation process, reducing construction difficulty and cost.
In addition, rubber plate expansion devices have been widely used in bridge engineering due to their advantages of low noise and multiple model choices, especially suitable for the renovation of old bridges, small bridges, and some bridges with low load capacity
Product advantages
The product advantages of rubber plate expansion devices mainly lie in good elasticity, excellent expansion performance, waterproof, dustproof and noise reduction, wear and aging resistance, affordability, and easy installation.
1. Good elasticity: The rubber plate expansion device adopts high-quality rubber materials with good elasticity, which can effectively absorb the vibration and deformation of the building structure, ensuring the stability and safety of the structure.
2. Excellent scalability: able to adapt to deformation caused by temperature changes or vibrations in buildings or roads, ensuring the stability and safety of the structure.
3. Waterproof, dustproof, and noise reducing: The rubber plate expansion device is coated with adhesive in the bolt holes at the bottom of the expansion joint and every meter of assembly, effectively preventing the intrusion of water, dust, and noise, protecting the interior of the structure from external environmental influences, extending its service life, and improving user comfort.
4. Wear resistant and aging resistant: The structure of rubber and steel plate or angle steel vulcanized into one allows the expansion joint to withstand the repeated loads of vehicles, and remains as tough as ever after the baptism of time, improving the service life of the expansion joint.
5. Economical: The rubber plate expansion device is affordable and can save users a lot of investment costs compared to other expansion joints. At the same time, its excellent expansion performance and medium resistance can also save users a lot of maintenance and replacement costs.
6. Easy installation: The rubber plate expansion device is assembled in sections and connected with bolts. The installation process is simple and fast, reducing construction difficulty and cost. At the same time, the joints are smooth, and the driving is smooth and comfortable.
These advantages have made rubber plate expansion devices widely used in bridges, buildings, and other engineering projects, becoming an indispensable part.

|
The working principle of the rubber plate expansion device is mainly to use the shear deformation of rubber material to adapt to the expansion and contraction displacement of the structure.
The expansion body in the rubber plate expansion device is made of rubber, steel plate or angle steel vulcanized into one. When external factors (such as temperature changes, load effects, etc.) cause the structure to undergo expansion deformation, the rubber body will undergo shear deformation, thereby absorbing and relieving the stress caused by these deformations. This shear deformation is achieved in the structural structure formed by connecting the load-bearing steel plate and anchor steel plate embedded in the rubber body with the beam end through bolts. It enables the rubber plate expansion device to freely expand and contract within a certain range, adapting to various deformation requirements of the structure. At the same time, rubber materials have good elasticity and resilience. When external factors disappear, the rubber body can automatically recover to its original state, achieving automatic expansion and contraction of the device. |

Product Structure
|
The rubber plate expansion device is mainly composed of a rubber, steel plate or angle steel vulcanized into one expansion body. The expansion body is equipped with upper and lower grooves, and load-bearing steel plates and anchoring steel plates are embedded, connected to the beam end through bolts.
Specifically, the expansion body of the rubber plate type expansion device is its core component, which is vulcanized from rubber and steel plates or angle steels. This structure gives the expansion body good elasticity and shear deformation ability. The upper and lower grooves set inside the telescopic body, as well as the embedded load-bearing steel plates and anchoring steel plates, are designed to adapt to the relative displacement of the beam structure. When bridges or buildings undergo expansion and contraction deformation due to temperature changes, load effects, and other factors, the rubber inside the expansion body will undergo shear deformation, thereby meeting the displacement requirements of the beam structure. At the same time, the expansion body is connected to the beam end through bolts, ensuring the stability and reliability of the entire device. |
