What are the advantages of road bridge steel mold

Road and bridge steel formwork can replace wood formwork, which significantly reduces the elimination of pore water pressure and bubbles in the concrete pressure caused by traditional sealed formwork such as wood, plywood or steel plate; after the road and bridge steel formwork structure is poured concrete, an ideal roughness interface is formed. Rough machining is not required to proceed to the next process. It can be placed before or after the reinforcement is installed. If it is placed before installing the steel bars, it is convenient and easy to place and install; the concrete pouring process can be visually monitored, thereby reducing the risk of porosity and honeycomb structure.

If large concrete pouring is interrupted or delayed for some reason, quick and easy road and bridge steel forms are ideal materials. As a spare part, it can be formed into the shape required for the emergency seal. Quickly resume construction without removing temporary end caps. Because the use of road and bridge steel formwork can quickly build unplanned plots as emergency measures.

Road and bridge steel mold is also called combined steel mold, which is composed of special-shaped plate, connecting piece and fulcrum. Let's take a brief look at the advantages of road and bridge steel molds.

1. Road and bridge steel formwork is more widely used than wood formwork

According to the operation scale, structure and construction technology of the project, the assembly, skidding and integral hoisting of road and bridge steel molds can be carried out. However, due to the single assembly structure of wood formwork, construction specifications cannot be reasonably considered.

2. Compared with wood formwork, road and bridge steel formwork has high precision and high bending rigidity.

The joints of the road and bridge steel molds are relatively tight, with high bending rigidity and not easy to deform at will. In general, the structural specifications of the formed concrete are relatively large to ensure greater flatness and compactness. The steel formwork section of road and bridge adopts through-seam arrangement and consists of decorative design control panel, which can ensure the overall bending rigidity of the plane.

3. The service life of road and bridge steel formwork is longer than that of wood formwork

Due to factors such as perishability and external damage, the service life of the wooden template is relatively short. However, due to its high structural rigidity and bending rigidity, the road and bridge steel mold cannot be deformed. It has a great advantage over wood templates in terms of service life.
