The anti-collision wall formwork is used to make cement side walls on the roads of bridges, expressways and provincial roads. The requirements for pressure resistance and heat resistance of the formwork are high. Generally, steel formwork is used. A complete set of steel formwork for anti-collision wall is assembled by two smooth inner wall panels, and the outer wall is provided with stiffening ribs to ensure that the panel does not deform. The front formwork is zigzag bending, and the rear formwork is straight plate. The thickness of the wall can be adjusted by bolts. The general height of the anti-collision wall is 81cm. When using, the floor type support is adopted. After fixing the steel formwork of the anti-collision wall, the inner wall is put into the prefabricated reinforcement and poured into C30 concrete. After 5-7 days of concrete solidification, the formwork can be removed for maintenance.
The anti-collision wall formwork is widely used in the construction of high-speed rail, which is a kind of infrastructure. When we are processing, we should make the design beautiful, have high uniqueness and functionality, and its production technology is constantly improving. The volume of this mold is larger, and the complexity is also increasing. At the same time, the design of flip edge is added, which can effectively make the mold It's more convenient to use. The production of the mold should be based on the needs of customers and the needs of the environment, so that the overall size of the steel mold, stable structure, demoulding method are within the consideration of the manufacturer. From the selection of raw materials, the high-quality steel panel will make the mold more solid and reliable, and it is the part that directly contacts with the concrete, so we should make the mold in the inner cavity It is coated with a layer of release agent to make the demoulding speed faster. Bridge deck cast-in-place concrete guardrail mold should pay attention to its accuracy standardization, the first thing to consider is the processing method, to make it more intelligent, can use numerical control processing, and pay attention to the inspection and acceptance of steel, when checking, the use of high-precision instruments, so that even if the surface of the mold is complex, the measurement data can be accurate.
