Abstract

To address the problems of severe damage to the pier concrete caused by wall attachments of components such as guide rails and low climbing efficiency in traditional hydraulic climbing formwork construction, a new type of hydraulic climbing formwork structure suitable for the construction of variable cross-section hollow thin-walled high piers was designed based on the Miaolu River Bridge project of the Zhengzhou ‒ Luoyang Expressway in this paper. To ensure the safety of the structure during construction, a finite element model of the climbing formwork structure was established using Midas Civil;the stress and deformation of components such as formwork, climbing formwork frame, operation platform, and support bracket were analyzed, and the stability of the structure was checked. The results show that the maximum combined stress of the formwork panel is 16. 85 MPa;the maximum combined stresses of the transverse and vertical ribs are 89. 18 MPa and 153. 52 MPa, respectively;the maximum deformations of the formwork structure are 4. 60 mm and 3. 68 mm;both the stress and deformation meet the requirements. The maximum stresses of the climbing formwork frame and the operation platform are 162. 16 MPa and 122. 97 MPa, respectively, which are both less than the yield strength of Q 235B steel;the maximum deformations are 7. 63 mm and 7. 98 mm, meeting the requirements. The support brackets are anchored to the pier body through bolts. The stability and safety factor are checked according to the maximum reaction force values at the connection points between the brackets and the pier body when the climbing of the climbing formwork structure is completed, and the results all meet the specification requirements. In the actual construction process, the climbing of the new hydraulic climbing formwork structure is completed by four vertical hydraulic jacks set on the support brackets, which is simpler and easier to operate and improves the construction efficiency.
