[0002] During the construction of highways, especially expressways, more and more viaducts are being built. During the construction of viaducts or elevated works, bridge piers are needed, and cap beams are arranged on the bridge piers. Bridge piers include double cylindrical piers, single cylindrical piers and hollow thin-walled piers. When building cap beams for double cylindrical piers or hollow thin-walled piers, it is necessary to set up formwork on two adjacent piers. The existing support method is to use a tower crane or a crane or a large crane to lift the cap beam formwork to the upper end of the pier, and then install the scaffolding and cap beam formwork.
