AI Technical Summary
In existing technologies, common methods for splicing wooden and steel formwork include bolt connection, which requires a large number of holes and is time-consuming and labor-intensive, and binding and fixing, which is only suitable for formwork with low strength requirements and is difficult to achieve fast and firm splicing.
A splicing fastener for bridge wooden formwork and steel formwork is adopted, including a back plate and a buckle plate, which are connected by bolts. The bolts pass through the buckle plate and the back plate and hook onto the flange of the I-beam. The back plate abuts against the top surface of the I-beam and the wooden formwork. The distance is adjusted by using nuts to achieve clamping, simplifying the splicing process.
This achieved a tight splicing of steel and wooden formwork, avoiding the safety hazards of loosening during construction and ensuring construction safety and efficiency.
