Steel structure connecting device of wood-stone composite bridge

Abstract

The invention discloses a steel structure connecting device of a wood-stone composite bridge. The steel structure connecting device of the wood-stone composite bridge comprises a cover nut (1), a lower semi-circular arc-shaped steel plate strip (2), a baffle plate (3), an upper semi-circular arc-shaped steel plate strip (4), a bolt hole (5), first end plates (61) and second end plates (62). The cover nut (1) is sleeved on a bridge pier, the lower semi-semicircular arc-shaped steel plate strip (2) is welded to the center of the top portion of the cover nut (1), the upper semi-circular arc-shaped steel plate strip (4) is arranged above the lower semi-circular arc-shaped steel plate strip (2), the first end plates (61) are arranged on two end portions of the upper semi-circular arc-shaped steel plate strip (4) along the radial direction far away from the center of a circle formed by the upper semi-circular arc-shaped steel plate strip (4) and the lower semi-circular arc-shaped steel plate strip (2), and second end plates (62) are arranged on two end portions of the lower semi-circular arc-shaped steel plate strip (2) along the radial direction far away from the center of the circle formed by the upper semi-circular arc-shaped steel plate strip (4) and the lower semi-circular arc-shaped steel plate strip (2). By means of the steel structure connecting device of the wood-stone composite bridge, the bridge pier built by laying stones and a longitudinal round-log beam are fixedly connected together, and the deformation requirement of the longitudinal round-log beam can be met.

Description

technical field [0001] The invention relates to a steel structure connection device for a wood-stone composite bridge, which is especially suitable for small-span simple bridges built in order to facilitate rural traffic in the construction of new rural areas in my country, especially in water towns in the south of the Yangtze River. It can be quickly spliced ​​with round wood stringers. Background technique [0002] The development of bridges can be roughly divided into three periods: ancient, modern and modern. [0003] In ancient times, people crossed waterways and canyons by using fallen trees, naturally formed stone beams and arches, protruding stones from streams, and vines growing on valley banks. Ancient bridges were generally constructed of wood and stone. According to research, as early as the Qin Dynasty, multi-span wooden bridges appeared in my country, such as the Wei Bridge built on the Wei River, and many cantilever wooden bridges and outrigger wooden bridges...

Problems solved by technology

However, due to long-term disrepair, long-term overloading and other reasons, many rural ancient bridges have suffered from surface peeling, structural damage, or even collapse.
