Steel sleeve prefabricated assembly type pier with shear nails

Abstract

The invention discloses a steel sleeve prefabricated assembly type pier with shear nails. The pier comprises a pier column 1 and a bearing platform 2. A steel sleeve 3 with the shear nails is connected with the bearing platform 2 and the pier column 1. The shear nails 4 on the part, connected with the pier column 1, of the steel sleeve are arranged on the inner side of the steel sleeve, and the shear nails 5 on the part, located in the bearing platform, of the steel sleeve are arranged on the outer side of the steel sleeve. Longitudinal ribs 6 embedded in a pier body are inserted into the part, located in the bearing platform 2, of the steel sleeve. The longitudinal ribs 6 and L-shaped rebars 8 are poured together, and an upsetting head 7 is reserved at the end, located in the bearing platform 2, of each L-shaped rebar 8. The steel sleeve with the shear nails is adopted for connecting the pier column and the bearing platform, a plastic hinge zone is wrapped with the steel sleeve in advance, the earthquake damage that a large amount of surface layer concrete peels off can be avoided, and the normal using performance can be restored through a little restoration work after earthquakes.

Description

technical field [0001] The invention relates to the technical field of road and bridge construction, in particular to a steel sleeve prefabricated assembled bridge pier with shear nails. Background technique [0002] At present, the substructure of urban bridges in my country usually adopts the method of cast-in-place construction. The disadvantage of this traditional construction process is that the construction period is long, which will bring many adverse effects on the urban environment and traffic. As my country's urban construction continues to advance, energy conservation, low-carbon, and environmental protection have gradually become the theme of my country's economic development. One of the main challenges facing the design of urban bridge structures is that urban residents and governments not only require the safety and durability of the structure, but also hope to reduce the interference to urban traffic and reduce various noises during the construction process th...

Problems solved by technology

The formation of plastic hinges is conducive to energy dissipation, but the plastic hinge area is also the area with relatively serious damage. When the vibration occurs, the concrete on the surface layer peels off a lot, and special measures need to be taken to repair it after the earthquake
