Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, specifically to a bridge steel formwork that is easy to assemble quickly. Background Technology

[0002] Steel formwork is widely used in the construction industry. It is a steel formwork used for concrete pouring and shaping. Steel formwork can be reused multiple times, and the poured concrete is aesthetically pleasing, making it a new type of formwork that "replaces wood with steel." The formwork must withstand the loads during the construction of concrete structures and is an important tool in concrete structure engineering.

[0003] Bridge steel formwork is generally fixed by bolts and has a support platform on the outside for easy construction. However, due to the large size of the bridge steel formwork, a large number of bolts are required for installation. At the same time, the installation of the support platform also requires a large number of bolts. Moreover, the space of the support platform is limited, and tightening the bolts requires repeated bending or standing. The labor intensity of assembling bridge steel formwork is high. Therefore, we propose a bridge steel formwork that is easy to assemble quickly. Utility Model Content
