Bridge Formwork System
Box girder formwork is a type of building that uses box girders as the main structural component. A box girder is a hollow beam with rectangular and box shaped cross-sections. It is usually used for bridge construction.

Box girder formwork
1. Introduction
Box girder formwork is a type of building that uses box girders as the main structural component. A box girder is a hollow beam with rectangular and box shaped cross-sections. It is usually used for bridge construction.The box girder formwork is used to support temporary structures of concrete during the construction process. It is usually made of steel and assembled on site.The box girder formwork is designed to give concrete the required shape and size, as well as support the weight of the concrete until it hardens and achieves structural strength.
2. Product Features
1. Widely used in all kinds of tunnel concrete construction.
2. Easy to use and flexible to disassemble.
3. Many turnover times, low cost amortization.
4. Concrete appearance quality is good.
5. Save labor costs, reduce engineering costs.
3. Product Advantages
1. light weight
2. The structure is simple, strong and stable
3. Easy to move, install and disassemble
4. Strong re-usability
5. Small stress and deformation
6. There is enough space under the hanging basket to provide large space for rod and formwork construction operations.
Segment formwork system
1. Introduction
The segment formwork is mainly used in the construction of cast-in-place concrete structures, especially in precast segmental bridge is very common, this technology allows different parts of the bridge to be poured concrete in the factory in advance and then transported to the site for installation.For pouring structures on construction sites, using segmental formwork can be poured in the site and ensure the consistency and strength of the structure.
2. Technical principle
The main beam is divided into appropriate lengths along the bridge and prefabricated into blocks, which are then transported to the construction site for installation, and the blocks become the whole bridge construction method after applying prestress.
3. Main feature
1) No brackets are required between the spans
2) During the construction process, the weight of the construction machinery and personnel is borne by the pier and the built beam segment, with the progress of the construction, the cantilever gradually extends, and the machinery and equipment are gradually moved to the beam end, and there is no need to support the beam from below.
3) Reduce the construction equipment, simplify the construction process
4) The porous structure can be constructed simultaneously to speed up construction.
5) The suspension assembly construction method makes full use of the strong negative moment bearing capacity of the pre-erected concrete structure, and transfers the positive curved rectangle in the span to the negative moment of the fulcrum, so as to improve the span capacity of the bridge.
6) Cantilever assembly construction can save construction cost and reduce the cost of T process.
