BOX GIRDER FORMWORK

详情

External formwork of *2/*4 meters post-tensioning concrete pre-fabricated box girder is divided into sliding mode and rolling mode; the side form of the first mode can move from one bottom form to the other one which increases the utilization rate, and decrease the investment for the formwork during construction; the side form of the second mode is relatively fixed according to the bottom form, and could be dismantled by revolving, which improve the efficiency of formwork closure. All the edges of external formwork panels for the box girder have been milled, which ensure the assembly precision to avoid the leakage of the concrete. The bottom formwork unit is 3 meters to facilitate the installation and anti-arch adjustment; the side formwork unit is mainly 6 meters, the design of the structure is compact and reasonable with beautiful and smooth appearance.  The bulkhead is designed to envelop the sideform, which can be wholly assembled, making the removal, installation and adjustment much easier.
