Support and fix the concrete structure: Bridge steel formwork is used to ensure the concrete can keep required shape and position during the construction process by providing necessary support and fixation. The steel formwork system can undertake the concrete weight and construction load, avoid the sinking and deformation, to ensure the accuracy and stability of bridge structure.
2. Formwork:Bridge steel formwork confirms the concrete pouring shape, dimension, curve and other parameters according to the design requirements and the complexity of building structure. By using bridge steel formwork, can ensure the accuracy and consistency of concrete structure.
3. Improve safety: Bridge steel formwork plays an important role in security during the bridge construction process. It can protect workers from falling from the high places or other construction hazards hurts, provide reliable work platform and supporting structure. In addition, bridge steel formwork can reduce the accident during the construction and ensure the safety of construction site.
4. Improve the construction efficiency: Using bridge steel formwork for column can greatly improve bridge construction efficiency. Compare to traditional wooden formwork, steel formwork is more stable and durable, and can be disassembled and moved fast. This can short the construction period, improve construction efficiency, and mostly reduce the project delay.
5. Reusability: Steel formwork for concrete is a reusable construction mode with long service life. Once one bridge construction is finished, steel formwork for concrete can be disassembled and reuse into other projects. This not only save resource and cost, but also reduce the impact on the environment.
● Steel formwork vs timber formwork
Steel formwork and wooden formworks are two commonly used formwork materials in the building construction. They have their own advantages and disadvantages.
The advantages of steel formwork:
1. High strength: Steel formwork is made of high strength steel, has good resistance to compression and bending, can bear large construction load.
2, Strong durability: Steel formwork has long service life, can be reused for many times. It is not easy to broken in use, saves the formwork investment and maintenance cost.
3 High construction efficiency: Steel formwork can achieve overall assemble and disassemble, easy to install, can greatly short the construction period, improve construction efficiency.
4. Flat formwork surface: Steel formwork has excellent manufacture process, the formwork surface is very smooth and flat, can meet the requirements of high demand building construction.
5. Good environmental performance: Steel formwork can reuse for many times, which can ease the shortage of forest resources to a certain extent.
Steel formwork disadvantages:
There are two disadvantage of steel formwork:
1, Has high requirement on building standardization: Steel frame formwork usually be designed at advance and carry out standardized production, this means, if the building structure is not standard enough, for example, if it has too many components, it has to modify the steel frame formwork, this will take more time and cost.
2, High requirement on management: Steel formwork is very heavy, need to be installed with a crane, so has high requirements on worker’s operation and construction skill. If the mangers are not skilled enough, the construction efficiency may lower than wooden formwork.
The advantages of wooden formwork:
High usage efficiency: The manufacture of wooden formwork is simple, it is easy disassembled, has high construction speed.
Good environmental performance: Wooden formwork mainly made of natural wooden and environmental coating, etc. it has few pollution to the environment during the construction.
Wide application range: Wooden formwork can be used to various parts of concrete structure construction, and has high customization degree.
Relatively low cost: Compare with other material formwork, such as steel formwork, aluminum formwork, the cost of wooden formwork is relatively lower.
The disadvantages of wooden formwork:
Easy to moisture and deformation: Wooden formwork is easy to be affected by humid environment, if not store correctly, it will suck the water and cause deformation, finally reduce its service life.
Easy to cause fire: The wooden formwork is easy to be fired, has bad anti-fire performance, and also easy to affect the surrounding environment.
Weak tightness: The interface of wooden formwork has weak tightness, which is easy to cause the concrete leakage, lower the project quality.
In general, both steel formwork and wooden formwork has their own advantages and disadvantages, users can make choice according to the special project situation, such as the standardization degree of building structure, construction period, environmental requirements, etc.
