Description

Technical Field

[0001] The present application relates to the field of construction, and in particular to a steel structure corridor bridge structure. Background Art

[0002] A covered bridge generally refers to a historical bridge with a corridor. It is an important type of bridge in China. It has a unique structure and beautiful shape. Its load-bearing structure is mostly wooden or stone beam bridges and arch bridges. Among them, the more Chinese-style subtypes include woven wooden arch bridges, braced arch bridges, and cantilevered wooden beam bridges.

[0003] The basic unit is six rods, four in the longitudinal direction and two in the transverse direction, with a "well" shape in the plane. The friction generated by the pressure makes the components tighter and tighter. This structure does not require nails or rivets, but only requires rods of the same specifications to be inserted and overlapped. Therefore, when building traditional covered bridges, felled trees are often used to make qualified components. However, with the development of the times, most people are no longer satisfied with the simple covered bridges built with trees, and have begun to use concrete and bricks to build more prosperous covered bridge structures, but this type of construction is more cumbersome and takes a long time. Therefore, it is urgent to provide a modern covered bridge structure with a short construction period and stable structure. Utility Model Content
