Seismic Isolation Method for Prefabricated Concrete Structure Floors

Abstract

The invention relates to a seismic isolation method for prefabricated concrete structures. In the first step, an upper connection hole is provided on the upper concrete column, and a lower connection hole is provided on the lower concrete column to make a rubber vibration isolation column; the second step is to install the rubber vibration isolation column. The lower end of the column is pierced into the connecting hole; the third step is to fix the upper concrete column liftably above the lower concrete column; the fourth step is to thread the upper end of the rubber vibration isolation column into the upper connecting hole; the fifth step Make the lower fixing claw overlap the inner flange of the lower hole and the upper fixing claw overlap the inner flange of the upper hole; step 6, pour concrete in the upper connection hole, and pour concrete in the lower connection hole; step 7, When the concrete in the upper connection hole and the concrete in the lower connection hole are solidified, the support structure is removed. The invention provides a prefabricated concrete structure layer vibration isolation method, which solves the problem of poor vibration isolation effect between the prefabricated concrete structure layers.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a method for floor vibration isolation of a prefabricated concrete structure. Background technique [0002] As the most important system of industrial buildings, prefabricated concrete structures have the advantages of high quality, short construction period, low energy consumption and green construction. my country has promulgated a series of policies to actively promote the development and promotion of prefabricated concrete structures (including structural components). The "Outline of the Thirteenth Five-Year Plan for National Economic and Social Development" and the State Council's "Several Opinions on Further Strengthening the Management of Urban Planning and Construction" proposed "to promote prefabricated buildings and strive to make prefabricated buildings account for new construction in about 10 years." The proportion of buildings reaches 30%" development goals a...
