Anti-corrosion anti-seismic combined column component and construction method thereof

Abstract

The invention provides an anti-corrosion anti-seismic combined column component and a construction method thereof, and belongs to the technical field of constructional engineering and bridge engineering. The problems that in the prior art, a column is poor in corrosion resistance and seismic resistance are solved, and meanwhile the problem that existing solid waste cannot be easily utilized so asto cause environmental pollution is solved. The component comprises a longitudinal bar, a grouting material, a composite material sleeve, a sizing material layer and a grid layer, wherein the longitudinal bar is located in a plastic hinge area, the longitudinal bar is sleeved with the composite material sleeve, the space between the longitudinal bar and the composite material sleeve is filled withthe grouting material, the sizing material layer is arranged on the outer side of the composite material sleeve, the grid layer is arranged on the outer side of the sizing material layer, and the composite material sleeve is a polyvinyl alcohol cement composite material doped with solid waste powder. The component is mainly used for column components of constructional engineering and bridge engineering technologies.

Description

technical field [0001] The invention belongs to the technical field of construction engineering and bridge engineering, and in particular relates to an anti-corrosion and anti-seismic composite column member and a construction method thereof. Background technique [0002] Columns are the main supports of buildings and bridges. In an earthquake, due to the serious damage of the columns, the whole collapsed and had to be stopped. Therefore, great attention should be paid to the design of the column. [0003] Judging from the existing development, many buildings and large bridges are being used in Northwest China and coastal areas. However, saline soil is widely distributed in Northwest my country. Engineering characteristics such as corrosion will have a serious impact on buildings and bridges. Saline soils contain high concentrations of corrosive chemical constituents compared to marine environments. According to seismic records, these areas are also earthquake-prone areas....

AI Technical Summary

Problems solved by technology

Among them, ceramics and glass, as one of the non-degradable solid wastes, not only occupy a large amount of land use area, but also cost expensive disposal fees, seriously polluting air and water quality

[0005] In the prior art, reinforced concrete materials are mostly used for on-site pouring in the construction of columns, but due to the high brittleness of concrete itself, poor bending resistance and poor corrosion resistance, it seriously affects the service life of the entire bridge

Under the earthquake, due to the corrosion of the internal steel bars, the seismic capacity of the bridge is greatly reduced
