Precast mould for segmental box girder

The prefabricated segment assembly process is to divide the beam into several segments and make the beam near the factory or construction site After prefabrication, it is transported to the bridge site, then hoisted and prestressed to assemble the segments as a whole into a construction technology of the bridge. The segmental box girder prefabricated formwork is a very important equipment in the process.

Segment box beam prefabricated template prefabrication process:

Features of segment box beam prefabricated formwork:

A set of segment box girder prefabricated formwork is mainly divided into the following parts: bottom mold, bottom mold trolley, Side mold and support, inner mold, inner mold trolley, fixed end mold and support, floating end mold and support, traveling mechanism, etc.

The mold clamping, demolding, and running functions of the template system are all realized by hydraulic or electric systems. The template and its support should not only meet the requirements of strength, rigidity and stability, but also meet the requirements of repeated use without deformation and ensuring the accuracy of segment prefabrication. The connection between the template and the matching section should be tight and not leaking.
