The main components of the steel structure pontoon bridge

Steel structure pontoon bridge usually consist of the following main components:

1. Pontoon: The pontoon is the basic buoyancy unit of the pontoon and is responsible for providing buoyancy to support the entire pontoon structure. Floating tanks can be made of steel, concrete or plastic and have sufficient load-bearing capacity. They are usually closed structures with air or foam inside to increase buoyancy.

2. Main Beams: The main beam is the key component connecting the pontoon and the bridge deck. It is usually made of steel. The main beam is responsible for transferring loads to the pontoon, supporting the bridge deck structure, and ensuring the overall stability and strength of the pontoon.

3. Bridge deck (Deck): The bridge deck is a platform for people and vehicles to pass, covering the main beam. Bridge decks can be constructed of steel plates, concrete, wood and other materials with load-bearing capacity and durability, and are usually designed with a non-slip surface to ensure safe passage.

4. Connections: Connections are used to connect and fix various components of the steel structure pontoon bridge, including connectors connecting the pontoon tank and the main beam, connectors between the main beam and the bridge deck, etc. The design and installation of connectors are critical to the overall performance of the pontoon and need to ensure that the connections are strong and stable.

5. Guardrails and Accessories: In order to increase the safety of pontoons, guardrails are usually set up along the bridge to prevent pedestrians or vehicles from accidentally falling. In addition, supporting facilities such as lighting facilities and signage may also be included to improve the visibility and convenience of the pontoon.

These components together form the basic framework of the steel structure pontoon bridge, which has load-bearing capacity, stability and safety, and is suitable for bridges that temporarily span water bodies.
